A kind of double-pull filter plate spiral vibration cake unloading filter press

Abstract

A spiral vibration cake unloading filter press that pulls the filter plate twice. The oil cylinder body is set as an elongated type, which means that multiple filter plates can be pulled apart for the first time to reach the distance between cake unloading. There are spacing chains between the filter plates. , the oil cylinder bracket is installed at the lower end of the oil cylinder body, the pull plate reduction motor is installed with a driving sprocket, the driving shaft is equipped with a passive sprocket, and a driving sprocket is arranged at both ends of the driving shaft, and the driving sprocket is connected with a passive chain, and the two driven shafts There is a driven sprocket at the end, and the middle partition is installed at the front end of the filter plate that is pulled apart for the second time. The spiral vibration cake unloading device includes a vibration deceleration motor and a coupling. There are bearing seats at both ends of the vibration shaft. One end of the vibrating shaft is connected to the coupling through the bearing seat. There are spirally arranged vibrating blocks on the vibrating shaft. Each vibrating block corresponds to the handle of a filter plate. At the head end of the main beam on the right, the structure is simple and has no failure rate, low cost and high efficiency, achieving the full recovery rate of the filter cake and improving economic benefits.

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.
