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.
