Description

Technical Field

[0001] The present application relates to the technical field of plate filters, and in particular to a plate filter. Background Art

[0002] The plate filter is a highly efficient filtration device, primarily used for filtering liquids and separating solid particles. It uses filter cloth to intercept solid particles in the liquid, separating them from the liquid and achieving a filtering effect. When the pores in the filter cloth become clogged, the feed needs to be stopped and cleaned. After cleaning, the feed can be resumed and the filtration operation can continue.

[0003] After searching, the announcement number: CN219091211U announced a plate filter, in which the raw liquid enters the filter cloth in the filter frame through the first oblique mouth for filtration, and the filtered raw liquid is discharged into the liquid outlet pipe through the second oblique mouth and the liquid outlet for reflux. During cleaning, the first electric push rod is energized and the output end of the first electric push rod drives the square plate to move outward, and the square plate drives the outer filter frame to move outward, then the slider slides outward in the slide groove, and through the rope, the filter frame produces a linkage reaction, and the filter frames are separated one by one. The servo motor is energized and the output shaft of the servo motor drives the threaded rod to rotate forward and backward through the bearing in the U-shaped plate, and the threaded rod rotates forward and backward in the threaded hole on the U-shaped frame, so that the U-shaped frame moves back and forth, and the U-shaped frame moves between the two filter frames. At this time, the second electric push rod is energized and the output end of the second electric push rod drives the L-shaped scraper to move downward to clean the filter cloth on the filter frame.

[0004] Regarding the above-mentioned related technologies, the inventors believe that there are the following technical defects that need to be improved:

[0005] When the traditional device is in use, fixed particulate matter will accumulate around the filter cloth to form a filter cake. This device is not equipped with a relevant collection structure. If the filter cake is not utilized and is directly discharged, the risk of environmental pollution will increase. Utility Model Content
