Pressing mechanism of filter press

Abstract

The invention discloses a pressing mechanism of a filter press. The pressing mechanism comprises a fixing plate is assembled on a filter press frame, an abutting plate abutting against a filter pressplate and frame assembly and being parallel to the fixing plate, and a hydraulic oil cylinder arranged between the abutting plate and the filter press frame, a fixing column for pressing the edge of afilter pressing plate is fixedly connected to the abutting plate, a pushing plate is fixedly connected to the fixing column, and the pushing plate is fixedly connected with a hydraulic oil cylinder.The pressing mechanism of the filter press realizes uniform stress of the hydraulic oil cylinder on the abutting plate, and can detect the stress of the abutting plate by an inspection and adjustmentdevice arranged between the pushing plate and the abutting plate, and the stress of the abutting agent is rapidly detected and can be adjusted if a detection result shows that the local stress of theabutting plate is uneven, so the abutting plate can stably and evenly apply a force to press the filter pressing plate, thereby the wastewater and waste residue filtering efficiency of the filter pressing plate and frame assembly is further improved.

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] Plate filter press is also plate and frame filter press, 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 hol...

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
