Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to a filter plate lifting device. Background Art

[0002] The filter press uses a special filter medium to apply a certain pressure to the object, so that the liquid can be dialyzed out. It is a mechanical device that is commonly used for solid-liquid separation. The filter press consists of a frame, filter plates, filter cloth, a clamping mechanism, a hydraulic system and an electronic control system. When working, the clamping device pushes the push plate to press the filter plate and filter cloth between the head and tail plates, so that a filter chamber is formed between the pressed filter plate and the filter cloth. The material pressed by the material pump enters each filter chamber from the feed hole of the tail plate. The solid particles are trapped in the filter chamber and form a filter cake. The liquid passes through the filter cake and the filter cloth and is discharged from the machine through the liquid outlet.

[0003] Most coal preparation plant filter presses can be installed with about 80 filter plates. The filter plates need to be replaced and maintained regularly, and they are installed and removed by lifting with a workshop crane. The replacement and installation of filter plates is an important lifting operation process. The filter plates of new coal mine filter presses are large in size, with a size of 2000×2000mm. During the replacement process, the traditional process often uses lifting belts for lifting. This lifting method is prone to slipping, causing personal injury and filter plate slippage, damaging the filter plate and filter press. During the lifting process, the lifting operator is prone to shaking and slipping due to the lack of a special filter plate replacement device, which poses a relatively large risk to personal safety. At the same time, during the installation of the filter plate, it is difficult to control the landing point and the installation quality is poor. In addition, the existing filter plate replacement device can only lift one filter plate at a time, and the work efficiency is low.

[0004] Therefore, the prior art needs to be further developed. Utility Model Content
