A compression mechanism for a filter press

Abstract

The invention discloses a compression mechanism of a filter press, which comprises a fixed plate assembled on a frame of a filter press, an abutment plate abutted against a filter plate frame assembly and parallel to the fixed plate, and an abutment plate arranged on the abutment plate The hydraulic cylinder between the frame of the filter press is characterized in that: the abutment plate is fixedly connected with a fixed column for pressing the edge of the filter plate, and a push plate is fixedly connected with the fixed column, and the The push plate is fixedly connected with the hydraulic cylinder. The filter press presses the mechanism so that the hydraulic cylinder can exert a uniform force on the abutment plate. The function of detecting the force of the abutment plate, if the local uneven force of the abutment plate is detected, the abutment plate can be quickly detected and the force of the abutment plate can be adjusted, so as to realize the abutment plate. The filter press plate performs the function of stable and uniform pressure and compaction, further improving the filtration efficiency of waste water and waste residue in the filter press plate frame assembly.

Description

technical field [0001] The invention relates to the technical field of filter presses, in particular to a pressing mechanism of a filter press. Background technique [0002] A plate filter press is also a plate and frame filter press. The plate filter press has a large filtration area, a large flow rate, and a wide range of applications, so it is widely used in chemical and other industries. The plate filter press is made up of plates and frames arranged alternately. The two sides of the filter plate are covered with filter cloth, and the plate and frame are compressed with a pressing device, that is, a filter press chamber is formed between the plate and the frame. There is a small hole in the same part of the upper end of the plate and the frame. After being compressed, it becomes a channel. The sludge pressurized to 0.2-0.4MPa enters the filter chamber through this channel. The surface of the filter plate is engraved with grooves. There are holes for the filtrate to be ...

Problems solved by technology

[0003] At present, when the compression mechanism in the existing filter press is in operation, the compression mechanism needs to be used to compress a plurality of filter plates, and in the process of compression, the area of ​​the abutting plate is relatively large, The attachment area between the output end of a hydraulic cylinder and the abutment plate is small, which leads to a large pressing force at the contact part of the abutment plate, and at the same time, the pressing force at other positions is small. Long-term use may easily lead to abutment The plate is deformed, and at the same time, it causes uneven force between the filter plate and the abutment plate, which leads to the weakening of the filtration effect of the wastewater and waste residue in the filter plate frame assembly. For this reason, we propose a filter press compression mechanism
