Description

Technical Field

[0001] The utility model relates to the technical field of plate-frame filter presses, and in particular to a filter residue collecting device for a plate-frame filter press. Background Art

[0002] Plate and frame filter press is the first machine used in chemical dehydration. Although plate and frame filter press is generally intermittent operation, the capital equipment investment is large, and the filtering capacity is also low, it is still widely used in some small sewage treatment plants because of its advantages such as large filtering driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning drugs.

[0003] In the prior art, the utility model with authorization announcement number CN212440214U is named: a plate and frame filter press. The patent drives the mounting rod to rotate through a rotating motor, drives the two second sprockets to rotate through the mounting rod, drives the two first sprockets to rotate through the two second sprockets and two chains, drives the two rotating rods to rotate through the two first sprockets, drives the two gears to rotate through the two rotating rods, drives the two racks to move upward through the two gears, drives the two fixed plates to move through the two racks, and drives the bracket to move upward through the two fixed plates, thereby completing the height adjustment of the filter press body. The utility model is convenient for adjusting the height of the filter press body, convenient for meeting people's usage needs, simple in structure, and easy to use.

[0004] However, after the sewage filtration is completed, this patent still requires manual cleaning of the filter residue inside the plate and frame filter press, which is rather troublesome.

[0005] In the prior art, there is a utility model with the authorization announcement number CN219783929U, named: Plate and frame filter press. This patent installs the filter plate through a fixing mechanism. When the filter plate moves in the frame, the slider slides in the slide groove. At this time, the rotating shaft rotates in the rotating groove, that is, the rotating shaft and the slide groove have rolling friction, which can greatly reduce the sliding friction between the slider and the slide groove, and even eliminate the need for friction between the slider and the slide groove. Only a small amount of lubricating oil needs to be applied in the slide groove, or even no lubricating oil is needed. Therefore, it can achieve the effect of preventing the lubricating oil from dripping through the frame to the ground and causing people to slip.

[0006] However, this patent still requires manual cleaning of the filter residue inside the filter frame, which increases the labor intensity of the staff. Utility Model Content
