Sludge feeding system for plate-and-frame filter press

Abstract

The invention discloses a sludge feeding system for a plate-and-frame filter press and belongs to the technical field of sewage disposal. The sludge feeding system for the plate-and-frame filter press comprises a sludge tank, a sludge feeding pump, a plate-and-frame filter press and a controller, wherein an input end of the sludge feeding pump is communicated with the sludge tank while an output end is communicated with the plate-and-frame filter press; the controller is connected with the sludge feeding pump and the plate-and-frame filter press; a liquid level meter is arranged in the sludge tank; the controller is used for controlling the sludge feeding pump to open or close according to the liquid level height detected by the liquid level meter; the sludge feeding pump is used for conveying a sludge water mixture in the sludge into the plate-and-frame filter press; the plate-and-frame filter press is used for performing solid-liquid separation. According to the invention, the sludge feeding system for the plate-and-frame filter press can automatically run under the action of the controller, the sludge feeding pump can be protected and prevented from idle running, the workload of the worker can be reduced and the whole service life of the system can be prolonged.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a mud feeding system for a plate and frame filter press. Background technique [0002] Sewage treatment is a process in which sewage is treated for discharge or reuse. Sewage treatment is widely used in construction, agriculture, petrochemical, environmental protection and other industries. [0003] At present, plate and frame filter presses are often used in sewage treatment stations for sewage treatment, and the mud-water mixture needs to be transported to the plate and frame filter press during sewage treatment. There are two commonly used mud feeding methods: screw pump and pneumatic diaphragm pump. When using a screw pump to feed mud, the staff needs to keep checking the pressure gauge on the mud inlet pipe to control the screw pump, and at the same time constantly observe the mud in the sludge tank to prevent the screw pump from running without load. In addition...
