Vibration discharging plate frame type slurry press filter

Abstract

The invention relates to the field of sludge treatment equipment, in particular to a vibration discharging plate frame type slurry press filter. The vibration discharging plate frame type slurry pressfilter comprises a machine frame, a press filtering device, a pressing device and a vibration device, wherein the press filtering device comprises a plurality of filtering frames and filtering platesarranged at two sides of the filtering frames; slide rails are arranged at two sides of the machine frame along the extending direction; a slide supporter is arranged on each slide rail; the bottom of each filtering frame is arranged on the slide supporter; each filtering plate is made of elastic materials; the lower part of the filtering plate and the filtering frame are in fixed installation; two connecting rods are hinged to the top of each filtering frame; the upper part of each connecting rod is provided with a bent part; one connecting rod is hinged to one connecting rod of the filtering frame at the front part at the top; the other connecting rod is hinged to one connecting rod of the filtering frame at the rear part at the top; the middle part of each connecting rod is provided with a spring; the bottom of the spring is connected with the top of the filtering plate; one side of the spring is provided with a press rod; the vibration device comprises a vibration air cylinder arranged on the machine frame and a press disc fixedly connected with a vibration air cylinder connecting rod. The press filter provided by the invention has the advantage that the automatic falling of mud cake can be promoted.

Description

technical field [0001] The invention relates to the field of sludge treatment equipment, in particular to a plate-and-frame mud filter press for vibrating discharge. 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, and the sludge is squeezed and filtered into cakes and then incinerated. The mud cake of the existing plate and frame filter presses is in the process of moving the filter frame. Free fall, however, due to the stickiness of the mud cake, it often sticks to the filter plate and cannot fall off. It needs to be shaken off manually, which is troublesome, time-consuming and laborious. Contents ...
