Sludge treatment filter press with function of easily replacing filter cloth

Abstract

The invention relates to the technical field of replacement of filter cloth of filter press, relates to a sludge treatment filter press with a function of easily replacing filter cloth. The filter press comprises a supporting rack, a press plate is fixedly connected in the supporting rack, the upper portion of the pressure plate is movably connected with a roller, the two sides of the roller are movably connected with a rotary shaft, a flow guide plate is movably connected to the portion, on the lower potion of the press plate, in the supporting rack, the two sides of the flow guide plate aremovably connected with spring blades, and the side, away from the press plate, of the flow guide plate is movably connected with a rolling body. Due to the action of an oblique plate arranged on the bottom, the gravity center of the rolling body is changed, so that the rolling body rotates; due to rotation, the filter cloth can be separated from the surface of the roller, while the filter cloth ispulled, the surface of the filter cloth can be scratched by the spring blades, when the rolling body rolls to the side away from the flow guide plate, water and sludge in a hollow channel can be separated out due to the action of gravity, and therefore, the effects that the using condition of the filter cloth is precisely controlled and the filter cloth is automatically replaced are achieved.

Description

technical field [0001] The invention relates to the technical field of filter cloth replacement for filter presses, in particular to a filter press for sludge treatment which is convenient for replacing filter cloths. Background technique [0002] The filter press is a machine that applies mechanical force on one side of the filter medium to achieve filtration. It is mainly used for solid-liquid separation of sludge. Among them, the plate and frame filter press is a very mature dehydration equipment and has been used in many international dehydration projects. use. [0003] The plate and frame filter press is a kind of intermittent solid-liquid separation equipment. It is composed of filter plates and filter frames to form a filter chamber. Solids and liquids are separated. Although this kind of filter press works efficiently, but because of its too many filter chamber structures, when one of the parts is damaged, it is troublesome to replace, and the filter cloth is an ind...

Problems solved by technology

[0003] The plate and frame filter press is a kind of intermittent solid-liquid separation equipment. It is composed of filter plates and filter frames to form a filter chamber. Solids and liquids are separated. Although this kind of filter press works efficiently, but because of its too many filter chamber structures, when one of the parts is damaged, it is troublesome to replace, and the filter cloth is an indispensable part of a filter press. , and the filter cloth is a consumable, which must be replaced after a period of use, otherwise it will lose its original function

[0004] For the replacement of filter cloth, it is often necessary to disassemble the equipment step by step, and then replace the old and new filter cloth. When installing the new filter cloth, it needs to be positioned, and finally the filter plate is installed between the filter plate and the filter frame. , and then use a special tightening mechanism to tighten it, and the tightening force cannot be too large or too small. In addition, the existing filter press often judges the replacement of filter cloth according to the use time, which cannot be accurately grasped. The use of the filter cloth, and it cannot be replaced automatically. If the time is not well controlled, once the filter cloth is damaged, it will cause immeasurable losses. Therefore, a filter press for sludge treatment that is easy to replace the filter cloth came into being.
