Device for automatically detecting tripping of filter plate of filter press

Abstract

The invention discloses a filter press filter plate tripping automatic detection device, which comprises a filter press main body, a conveying mechanism, a PLC controller, a filter plate main body and an electric lifting rod, one end of the filter press main body is provided with the conveying mechanism, the bottom end of the filter press main body is provided with a support frame, the inner part of the filter press main body is provided with a transmission mechanism, and the transmission mechanism is connected with the PLC controller. A transmission mechanism is installed on the side wall of one side of the filter press main body, a chain is arranged in the transmission mechanism, a U-shaped frame is installed on the side wall of one side of the filter press main body, the outer wall of the chain is sleeved with the U-shaped frame, the outer wall of the U-shaped frame is sleeved with plate pulling trolleys, and fixing frames are installed at the top ends of the plate pulling trolleys. According to the filter press filter plate tripping automatic detection device, whether the pull plate trolleys on the two sides of the filter plate main body are provided with the proximity switches or not is judged through the PLC, whether the pull plate is normally suspended or not can be conveniently confirmed, and therefore an operator can be rapidly alarmed, and the phenomenon that the filter plate and a track are obliquely pulled, and equipment and personnel danger is caused is avoided.

Description

technical field [0001] The invention relates to the technical field of filter press processing, in particular to an automatic detection device for filter plate tripping of a filter press. Background technique [0002] With the continuous promotion of China's mechanized coal mining technology and the rapid development of coal preparation technology, the automatic pull plate mechanism of filter press in coal preparation plant includes frequency conversion motor, clutch, sprocket, chain, pull plate trolley, proximity switch, etc. It is a plate frame It is an important part of the filter press. It drives the left and right trolleys to take out the plates through the chain. The plate motor starts to drive the trolley to start to take out the plates. After the inverter sends an overload signal, it automatically reverses to the state of the plate. If the inverter sends out an overload signal, it will switch to the state of plate removal. This is the cycle of plate extraction and pu...

Problems solved by technology

[0004] The purpose of the present invention is to provide an automatic detection device for filter plate tripping of a filter press, so as to solve the problem that if one side of the trolley is hung with a plate and the other side of the trolley is not. The track is inclined, or even derailed and the board is dropped, causing dangerous problems for equipment and personnel
