Cloth folding device of filter press

Abstract

The invention discloses a cloth folding device of a filter press. The cloth folding device comprises a machine frame, an upper filter cloth operation assembly, a lower filter cloth operation assembly, a sludge discharging mechanism, a sludge separating and pressing mechanism, a sludge pressing roller and a cloth folding and feeding mechanism, and each of the upper filter cloth operation assembly and the lower filter cloth operation assembly comprises a cloth rolling mechanism, a roll feeding deviation measuring mechanism and a filter cloth deviation correcting mechanism. The cloth rolling mechanism comprises a cloth rolling roller capable of moving in the axial direction of the cloth rolling mechanism and rotating around the axis of the cloth rolling roller, the cloth rolling roller moves in the axial direction of the cloth rolling roller to adjust the position according to the detection result of the roll feeding deviation measuring mechanism, and the filter cloth deviation correcting mechanism rectifies the filter cloth; the sludge separating and pressing mechanism comprises a sludge pressing plate, the sludge pressing plate is provided with a horizontally arranged sludge pressing part, and the length of the sludge pressing plate is at least equal to the width of the lower filter cloth; the arrangement height of the sludge pressing roller is adjustable, the axis of the sludge pressing roller is perpendicular to the moving direction of the lower filter cloth, and the cloth folding and feeding mechanism is located at one end of a rack and used for conveying a sludge bag formed by wrapping sludge with the upper filter cloth and the lower filter cloth. The filter cloth can be automatically rectified, the filter cloth is kept flat, and sludge leakage is prevented.

Description

technical field [0001] The invention belongs to the technical field of filter press equipment, and in particular relates to a layering device for a layered filter press. Background technique [0002] The filter press is a solid-liquid separation device, and its working principle is to use pressure to force out the water in the filter medium. At present, there are mainly two types of equipment for deep dehydration of sludge: horizontal filter press and vertical filter press. The cloth-stacked filter press in the vertical filter press can simultaneously press and filter the multi-layer filter cloths stacked in the filter press frame, which has the characteristics of high efficiency. For example, the Chinese invention patent application with the publication number CN110922018A discloses a laminated filter press equipment, which includes a cloth laying assembly, a mud distribution device and a pressing device. The cloth stacking device on the cloth stacking frame, the cloth st...

AI Technical Summary

Problems solved by technology

However, since this kind of stacked cloth filter press distributes mud on a very long filter cloth and then stacks the filter cloth into the filter press frame for press filtration, the filter cloth is prone to bias when distributing mud or unloading mud. , if the filter cloth is biased, not only is it easy to cause sludge leakage during the filter press process, but it will also cause the filter cloth to wrinkle and become uneven, making it inconvenient to collect the cloth and unload the mud

In addition, the insufficient tension of the filter cloth will cause wrinkling or unevenness, which will affect the length of the cloth, so that the length of the filter cloth when feeding the cloth mud is not equal to the length when the filter cloth is unloaded and collected. The length of the filter cloth recovered by the cloth rolling roller after the second cloth and mud discharge cycle is less than the length of the cloth, which affects the subsequent normal use of the filter press
