Spiral vibration cake unloading filter press by pulling filter plates twice

Abstract

The invention provides a spiral vibration cake unloading filter press by pulling filter plates twice. An oil cylinder body is set to be lengthened, that is, the multiple filter plates can be pulled for the first time to reach the spacing of cake unloading, spacing chains are arranged among the filer plates, an oil cylinder bracket is installed at the lower end of the oil cylinder body, an active chain wheel is installed on a pull plate gear motor, a passive chain wheel is installed on an active shaft, driving chain wheels are installed at the two ends of the active shaft and are connected withpassive chains, driven chain wheels are installed at the two ends of a passive shaft, a middle clapboard is installed at the front end of a filter plate pulled for the second time, spiral vibration cake unloading devices comprise vibration gear motors and couplers, bearing bases are arranged at the two ends of each vibration shaft, one end of each vibration shaft is connected with the corresponding coupler through the bearing bases, spirally arranged vibration blocks are arranged above the vibration shaft, each vibration block corresponds to a handle of one filter plate, and the spiral vibration cake unloading devices are installed at the tail end of a main beam at the left side and the head end of a main beam at the right side respectively. The filter plate spiral vibration cake unloading filter press by pulling twice is simple in structure, free of fault rate, low in cost and high in efficiency, reaches the filter cake total recycling rate and increases economic benefit.

Description

technical field [0001] The invention belongs to the field of filter presses in the solid-liquid separation industry, and more specifically relates to a filter press for cake unloading with spiral vibration of a filter plate pulled twice. Background technique [0002] The filter press is the main filtering equipment in the solid-liquid separation industry. After the material is filtered, the plate puller pulls the filter plate to remove the filter cake. There are two types of filter press pull plate unloading cake. The second method is to pull apart the filter plates in groups to remove the filter cake. These two cake unloading methods are to pull the filter plate and then the filter cake will fall freely. The filter machine is equipped with a complete set of special pneumatic vibration device above the filter plate to drop the filter cake to realize the purpose of unloading the filter cake after the filtration is completed. [0003] In the field use of the filter press, it ...

AI Technical Summary

Problems solved by technology

[0003] In the field use of the filter press, it is found that the filter cake does not fall completely after the plate puller pulls the filter plate. Due to the complex composition of the filtered material, the filter cake in some materials contains stickiness and often hangs on the filter cloth in a large area. Difficult to fall, although some filter presses are equipped with a complete set of pneumatic rapping device to drop the filter cake, but because the components of the pneumatic rapping device are complex in structure, the failure rate is high during use, and maintenance is very inconvenient. Besides, the equipment components of the pneumatic rapping device The cumbersome investment costs are high, so it is not practical to use the filter plate to drop and unload the cake, which directly leads to low filtration efficiency and loss of economic benefits.
