Plate-frame type sludge and slurry filter press

Abstract

The invention relates to the field of sludge treatment equipment, especially to a plate-frame type sludge and slurry filter press. The plate-frame type sludge and slurry filter press comprises a rack,a press filter and a hold-down device. The press filter comprises multiple successively-arranged filter frames, filter cloth and filter boards. A thrust plate is fixedly installed at one end of the rack. A slide rail is arranged below the thrust plate and along the extension direction of the rack. The thrust plate is provided with a feed inlet. Multiple filter frame sliding holders and filter board sliding holders are respectively arranged in a staggered manner on the slide rail. The filter frame sliding holder is provided with a filter frame neck, and the filter board sliding holder is provided with a filter board neck. The filter frames are installed inside the filter frame necks, and the filter boards are installed inside the filter board necks. The filter frames and the filter frame sliding holders are provided with filter board sliding holder abdicators. The hold-down device is arranged at the other end of the rack and comprises a mounting base, a lead screw and a pressure strip,wherein the pressure strip is connected to an end portion of the lead screw through a nut cap; the lead screw passes through the mounting base and is controlled by a handle to rotate; and the lead screw is sleeved with a locknut between the mounting base and the pressure strip. According to the device of the invention, the filter frames and the filter boards are convenient and reliable to installand replace, extrusion is labor-saving, and reliable self-locking can be formed.

Description

technical field [0001] The invention relates to the field of sludge treatment equipment, in particular to a plate and frame sludge sludge filter press. Background technique [0002] Sewage treatment plants will produce sludge during the process of sewage treatment. Since there is still a large amount of water in the sludge, if it is not treated or treated improperly and discharged, it is not conducive to the incineration of sludge, and will give Water and air cause secondary pollution. Nowadays, plate and frame filter presses are often used in sludge dehydration treatment, which squeezes and filters the sludge into cakes and then incinerates them. Some of the existing plate and frame filter presses have filter frames and filter plates directly placed on them. On the frame, some are connected to a connecting pipe, and the filter frame and filter plate are directly placed on the frame. During the extrusion process, it is easy to cause the filter frame and filter plate to shak...

Since there is still a large amount of water in the sludge, if it is not treated or treated improperly and discharged, it is not conducive to the incineration of sludge, and will give Water and air cause secondary pollution

Nowadays, plate and frame filter presses are often used in sludge dehydration treatment, which squeezes and filters the sludge into cakes and then incinerates them. Some of the existing plate and frame filter presses have filter frames and filter plates directly placed on them. On the frame, some are connected to a connecting pipe, and the filter frame and filter plate are directly placed on the frame. During the extrusion process, it is easy to cause the filter frame and filter plate to shake, and the extrusion process is laborious, and the filter frame It is very inconvenient to install and replace the filter frame and filter plate through a connecting pipe with the filter plate, and the current extrusion device cannot form a reliable lock
