Description

A kind of mud scraping device for filter press

Technical field

The utility model relates to the technical field of filter presses, and more specifically, to a mud scraping device for a filter press.

Background technique

The filter press is a machine used to squeeze and filter liquid materials. Its main pressing and filtering component is the filter plate assembly. The filter plate assembly is composed of multiple filter plate units connected. Each filter plate unit includes a water template and a material template. , when working, the liquid material enters the filter cloth between the water template and the material template, and then applies pressure on both sides of the water template and the material template to squeeze the liquid out. The squeezed material becomes a mud cake and sticks to the water. On the template and material template, the mud cake needs to be removed after the pressing is completed. After the mud cake is removed, some sediment will remain on the filter plate. At this time, the sediment needs to be cleaned by a mud scraper device.

After searching, the utility model patent with announcement number CN210635878U discloses a sludge scraping device for a sludge plate and frame filter press, in which a sliding rod is provided between the two support frames, and a slider is slidably connected to the sliding rod. The first driving component drives and connects the slider. The bottom of the slider is provided with a first mechanical arm that can be telescopic in the vertical direction. The bottom end of the first mechanical arm is provided with a connecting portion. The second mechanical arm and the third mechanical arm are respectively provided on both sides of the connecting portion. Three mechanical arms, one end of the second mechanical arm away from the connecting part is rotatably connected to a fourth mechanical arm, one end of the fourth mechanical arm away from the second mechanical arm is provided with a first frame, and one end of the third mechanical arm away from the connecting part is rotatably connected to The fifth robotic arm is provided with a second frame at one end of the fifth robotic arm away from the third robotic arm. The first frame is provided with a first scraper that can move along the first frame, and the second frame is provided with a first scraper that can move along the second frame. The second scraper; this patent can automatically scrape mud from the plate frame to be scraped, reducing manual participation and improving work efficiency and work quality.
