Automatic sludge dewatering machine
Introduction of Automatic sludge dewatering machine

The main body of Automatic sludge dewatering machine is a filtration device consisting of a fixed ring and a moving ring laminated on top of each other, and a spiral shaft running through it. The front section is the thickening section, and the back section is the dewatering section. The filtration slit formed between the fixed and moving rings and the pitch of the spiral shaft gradually decreases from the thickening section to the dewatering section. The rotation of the spiral shaft drives the sludge from the thickening section to the dewatering section, and at the same time drives the moving ring to clean the filter slit to prevent clogging. After the sludge is thickened by gravity in the thickening section, it is transported to the dewatering section, where the slit and pitch gradually become smaller and the back pressure plate blocks the sludge, resulting in great internal pressure and volume reduction to achieve full dewatering.



Working principle of automatic sludge dewatering machine

1.Concentration: When the spiral pushing shaft is rotating, the multiple solid and live stacks located in the pushing shaft are relative to each other, and under the action of gravity, water is filtered out from the gap of the relative stacks to realize rapid concentration.

2.Dewatering: The concentrated sludge is continuously moved forward with the rotation of the spiral shaft; along the direction of the mud cake outlet, the pitch of the spiral shaft gradually becomes smaller, the gap between the ring and the ring also gradually becomes smaller, and the volume of the spiral cavity continuously shrinks; under the action of the back pressure plate at the outlet, the internal pressure gradually increases, and the water in the sludge is squeezed and discharged under the continuous operation of the spiral pushing shaft in turn, and the solid content of the filter cake continuously increases, which finally realizes Continuous dewatering of sludge is realized.

3.Self-cleaning: The rotation of the spiral shaft pushes the moving ring to rotate continuously, and the equipment relies on the continuous self-cleaning process between the fixed ring and the moving ring, thus cleverly avoiding the clogging problem that commonly exists in traditional dewatering machines.



What do you need to know about the operation, maintenance and management of Sludge treatment equipment?

1.When there are several people performing maintenance on the Sludge treatment equipment, notify them before turning on the power.

2.Avoid operating Sludge treatment equipment with electricity as much as possible, and operate with electricity only after the person in charge of electricity has approved and taken effective measures.

3. Do not blindly trust the switch or control device, only pull the switch, there is an obvious break point is safe. And put up the sign of "No closing, someone is working".

4.Sludge treatment equipment of any electrical device before the confirmation of no electricity, should always be considered to have electricity, do not casually touch the electrical device.

5.The disassembled or broken charged joints must be wrapped with insulating cloth in time and placed in a place not easily accessible to people.

6.Do not damage the wire, do not pull the wire indiscriminately. Electrical equipment such as wires, plugs or sockets are found to be damaged, promptly replaced.

7.Sludge treatment equipment charged devices around the use of steel tape measure or steel tape measure is prohibited for measuring work.



The working principle of Sludge treatment equipment

1. The main body of Sludge treatment equipment is a filtering device formed by the fixed ring and the moving ring stacked on top of each other and the spiral shaft running through it. The front section is the thickening section and the back section is the dewatering section.

2. The filtration slit formed between the fixed ring and the moving ring and the pitch of the spiral shaft gradually decrease from the thickening section to the dewatering section.

3. The rotation of the spiral shaft drives the sludge from the thickening section to the dewatering section while continuously driving the moving ring to clean the filter slit to prevent clogging.

4. After the sludge is concentrated by gravity in the thickening section, it is transported to the dewatering section, and in the process of moving forward, the filter slit and the pitch gradually become smaller, and the back pressure plate blocks the sludge, generating a great internal pressure and reducing the volume continuously to achieve the purpose of full dewatering.

After the sludge is thickened by gravity in the thickening section, it is transported to the dewatering section, and in the process of moving forward, as the filter slit and pitch gradually become smaller and the back pressure plate blocks the sludge, the internal pressure is generated and the volume is continuously reduced to achieve the purpose of full dewatering.



Automatic sludge dewatering machine acceptance criteria

Automatic sludge dewatering machine is a kind of equipment with compact design and small space, low energy consumption and low operating cost, high energy saving and high technical content, easy to maintain and replace, small weight and easy to carry. It is especially suitable for small and medium-sized sewage plants, township sewage plants and sewage treatment stations. So what are the acceptance criteria of Automatic sludge dewatering machine?

1.High sludge pressing force: Automatic sludge dewatering machine final output mud moisture content between 15%-45%, so that the volume of sludge after treatment is very small, more filtrate, get more.

2.High dewatering efficiency: The sludge treatment cycle of Automatic sludge dewatering machine is less than 40 minutes, thus the whole dewatering efficiency is 30% higher than the common filter press.

3.High degree of automation: For large sludge treatment projects, multiple machines can be networked to realize remote control, and several sludge filter presses can be managed by only one staff.

4.Low energy consumption: The energy consumption used by Automatic sludge dewatering machine is 1/3 lower than that of ordinary filter presses for the same sludge treatment, which reduces the sludge disposal cost for sludge treatment enterprises.

For the structure of the filter press, the main filtering effect occurs in the filter chamber, and the filter chamber is composed of a piece of filter plate, the center is mixed with a filter cloth, and the separation of solid and liquid requires a filter chamber. In a closed environment, it has to accept a certain resistance, so an effective force is added longitudinally to the filter plate to form a pressing effect on the filter plate. This effect force is called the pressure of the filter plate. Through this introduction, we understand that the effect of this pressure on the equipment is to make the filtrate form a closed environment. When the pressure changes, it will affect the acceptability of the filter chamber, thereby affecting the working ability of the chamber filter press equipment.

The pressure generated by the chamber filter press hydraulic pressure system can better meet the needs of the equipment. If the chamber filter press is to ensure its normal operation, the filter chamber needs to be kept in a closed and high-pressure environment. The necessary condition for the chamber filter press to produce this is that there must be strong pressure. The two forms of pressure (both human pressure and mechanical pressure) of the chamber filter press can only reach 78 MPa at the highest, while the pressure range of the hydraulic pressure is increased by several tens of MPa, and the chamber filter press is greatly satisfied. The need for filter presses began to develop. It paves the way for large-scale filter presses.

The chamber filter press hydraulic pressure system is easier to control. The hydraulic pressure system adopts the function of monitoring the whole section, and a controller for monitoring and detection is designed in every key part of the hydraulic oil. These controllers of the chamber filter press can very well convert the pressure into electronic signals all the time. In this way, the chamber filter press can imagine the exchange and communication between the computer control system and the hydraulic pressure system on the equipment, so that the chamber filter press can easily control the hydraulic system. This also creates the necessary conditions for the intelligentization of hydraulic filter press and automation of chamber filter press and provides a foothold for the future development of filter press.

When the pressure effect is applied to the filter plate, it must be ensured that the direction of the pressure effect is on the same line as the center point of the filter plate of the filter chamber, so as to keep each point of each filter plate can receive a uniform effect force, so as to avoid The uneven effect force will cause the leakage of the filter chamber, and if the filter plate is subjected to uneven force for a long time, it will cause the deformation of the filter plate part, and in severe cases, the filter plate will burst and cause unforeseen damage. When the pressure on the filter plate is applied, it can also be transmitted to the filtrate through the filter plate, thereby adding kinetic energy to the filtrate, allowing the liquid to pass through the filter cloth faster and increasing the working efficiency of the equipment.

The above is the introduction of how the chamber filter press generates pressure, I hope it will be helpful to everyone.
