Problems solved by technology
[0004] The reason why the belt filter press treats the sludge with a moisture content of 80-85% is that the belt filter press only relies on the tension of the filter belt, and cannot perform high-pressure press filtration like a plate and frame

Embodiment Construction
[0048] The present invention will be further described below in conjunction with specific embodiments. The exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.
[0049] A sludge dewatering filter press for environmental protection, which adopts a cyclical process regionalization design. The entire process is divided into a mud inlet area, an adjustment area, a pressurization and holding area, Opening and closing area, lower mud wash area and upper mud wash area.
[0050] The specific components of the entire filter press include a lower circulation chain 1, an upper circulation chain 2, a driving sprocket 3, a passive sprocket 4 and an auxiliary sprocket 7, wherein a group of driving sprockets 3 and passive sprockets 4 are connected to the lower The endless chain 1 forms the lower endless chain, another set of driving sprockets 3 and passive sprockets 4 and the upper endless...

The invention provides an environmentally-friendly sludge dewatering filter press. The environmentally-friendly sludge dewatering filter press is suitable for the deep dewatering treatment process ofsludge. The sludge dewatering filter press is divided into a sludge inlet area, an adjusting area, a pressurizing and pressure maintaining area, an opening and closing area, a lower sludge scraping and washing area and an upper sludge scraping and washing area according to the operation process by adopting a modular design thought, the whole circulation process is synchronously driven through chains, and water in sludge is filtered out by applying pressure to the sludge in a closed cavity, so the water content of the sludge is reduced. The sludge is sealed by using a reverse sealing sheet, andthe sealing effect is good when the pressurization pressure is high, so that the high-pressure filter pressing of the sludge is realized; and the whole process is continuously circulated, the pressurization process is progressive, and each working area is relatively independent, so the working efficiency of continuous filter pressing effluent is improved.
Description
technical field [0001] The invention provides a sludge dewatering filter press for environmental protection, which belongs to the field of sludge treatment equipment, in particular to the field of deep sludge dehydration treatment. Background technique [0002] As the country's requirements for environmental protection become more and more stringent, environmental protection equipment in various industries is also facing reform and upgrading. At this stage, the sewage treatment of sewage plants is becoming more and more stringent. At the present stage, the way sewage plants treat the generated sludge can't keep up with the requirements of environmental protection. The national standard requires that the sludge landfill standard of the sewage plant is that the moisture content of the sludge is below 60%, while in the existing equipment, the sludge moisture content after treatment by the stack filter press and the belt filter press is generally 80-85% %, unable to meet the la...
