Filter cloth desilting and cleaning device of diaphragm plate-and-frame-type filter-press

Abstract

The invention discloses a filter cloth desilting and cleaning device of a diaphragm plate-and-frame-type filter-press. The filter cloth desilting and cleaning device of the diaphragm plate-and-frame-type filter-press comprises a protective cover, wherein draw chains are connected with the outer wall of the top of the protective cover, two cleaning air cylinders are installed on a baseboard of an inner cavity of the protective cover, push rods of the cleaning air cylinders penetrate through the baseboard of the protective cover, and are installed on installation boards, two ends of the top of each installation board are connected with one end of each guiding rail, the guiding rails are sleeved with the baseboard of the protective cover, a plurality of cleaning heads are installed on side walls of the installation boards, the cleaning heads are connected with certain ends of hoses, water source pipes are arranged in the protective cover, the water source pipes are connected with the other ends of the hoses, a desilting air cylinder is installed at one end of the bottom of the protective cover, and a position sensor is installed at one end of the corresponding installation board. Thedraw chains drive the protective cover to slide to make the protective cover located on the upper portion of a to-be-cleaned filter board, the desilting air cylinder repeatedly stretches out and drawsback to make a filter cloth frame on the filter board vibrate so that silt on the filter cloth can be shaken off, the push rods of the cleaning air cylinders drive the installation boards to move vertically on the filter cloth on the two sides of the filter board, and through the hoses and the water source pipes, the cleaning heads on the installation boards spray high-pressure water flows to thefilter cloth to clean the filter cloth.

Description

technical field [0001] The invention relates to the technical field of filter presses, in particular to a filter cloth desliming and cleaning device of a diaphragm plate and frame filter press. Background technique [0002] Diaphragm plate and frame filter presses are in great demand in chemical, petrochemical, food, pharmaceutical, military manufacturing and other fields. Squeeze the sludge through the filter plate and filter the water through the filter cloth. Finally, it is necessary to remove the sludge and clean the filter cloth. The desilting method of the plate and frame filter press on the market is to manually desilt and clean it with a small shovel. This method increases the operating cost of the user and costs A lot of time, there are also personal safety issues. There is also a so-called automatic method, which is to lift up the filter plate armrests on both sides with a cylinder, and then put it down. Great damage shortens the service life of the filter plate. ...

[0002] Diaphragm plate and frame filter presses are in great demand in chemical, petrochemical, food, pharmaceutical, military manufacturing and other fields. Squeeze the sludge through the filter plate and filter the water through the filter cloth. Finally, it is necessary to remove the sludge and clean the filter cloth. The desilting method of the plate and frame filter press on the market is to manually desilt and clean it with a small shovel. This method increases the operating cost of the user and costs A lot of time, there are also personal safety issues. There is also a so-called automatic method, which is to lift up the filter plate armrests on both sides with a cylinder, and then put it down. Great damage shortens the service life of the filter plate, so we propose a filter cloth desliming and cleaning device for the diaphragm plate and frame filter press to solve the above problems
