Description

A fully automatic filter press unloading auxiliary device

technical field

The invention relates to the field of filter presses, in particular to a fully automatic filter press unloading auxiliary device.

Background technique

Existing filter presses are mainly used for the separation of solids and liquids. Specific applications include dehydration of clean coal, tailing coal, and primary coal slime, increasing the degree of mud cake, and reducing the moisture content of mud cake. The constituent unit of the filter press is mainly a group of filter chambers composed of alternately arranged filter plates and filter frames (both sides of the filter plates are recessed, and every two filter plates are combined to form a box-shaped filter chamber). Points and bosses are used to support the filter cloth, and there are through holes in the center and corners of the filter plate, which form a complete channel after assembly, which can pass into the suspension, washing water and lead out the filtrate. There are handles on both sides of the filter plate to support the beam, and the filter plate is pressed by the pressing device, and the filter cloth between the filter plates acts as a seal. When the filter press is working, the feeding pump provides pressure, and the material liquid to be filtered is sent into each filter chamber, and the solid and liquid are separated through the filter medium (select the appropriate filter cloth according to different industries). The filtrate passes through the filter cloth and flows along the groove of the filter plate to the channel of the outlet hole below, where it is discharged in a concentrated manner. The filter residue remains on the filter cloth until it fills the filter chamber and forms a filter cake. After the filtration, open the filter press to remove the filter cake (the filter cake is stored between two adjacent filter plates), clean the filter cloth, and re-press the plate filter to start the next working cycle.

Existing filter presses are mainly used for dehydration of clean coal, tailing coal, and primary coal slime. Since the automatic dehydration of the mud cake from the filter cloth after dehydration is mainly dependent on the gravity of the mud cake itself, it is difficult for the mud cake to be removed from the filter press. The filter cloth on the plate falls off naturally or there is incomplete discharge, which requires additional labor. It is necessary to use manual power to make the mud cake sticking to the filter cloth fall off, which greatly reduces the dehydration efficiency of the filter press. At the same time, a large amount of labor costs are also invested to assist the work of the filter press, which is time-consuming and labor-intensive, which seriously affects the working efficiency of the filter press, making it unable to fully play its due role and value in the work. Waste of resources.
