Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a self-cleaning device for a filter press. Background Art

[0002] A filter press is a mechanical device that uses a special filter medium to exert a certain pressure on an object to allow liquid to seep out. It is a commonly used solid-liquid separation device and is widely used in chemical, pharmaceutical, metallurgical, dye, food, and environmental protection industries.

[0003] In the prior art, for example, a plate filter press disclosed in patent CN215085125U, after the filtration is completed, water is pumped into the water outlet pipe through the water inlet pipe, and then the water is ejected outward in an umbrella-shaped manner along the nozzle, which cleans the filter residue adhering to the filter frame. After the cleaning is completed, the cleaning water mixed with the filter residue will be discharged from the liquid outlet. Although there is no need to disassemble the filter frame, which has the technical effect of convenience and labor saving, this filter press still has the following problems when in use:

[0004] When performing solid-liquid separation, some viscous liquids are prone to sticking to the wall when discharging. The diameter of the bucket-shaped discharge port is small, which makes it inconvenient to clean the inner wall and increases the cleaning pressure of the filter press. Therefore, there is still room for improvement. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-2 As shown, the self-cleaning device of the filter press in this embodiment includes:

[0027] The filter press body 1 has a filter frame 2 inside, and a plurality of nozzles 3 inclined at different angles are provided on the inner wall at the top of the filter frame 2 for flushing the filter frame 2 and the inner wall of the filter press body 1; wherein, the structure and connection method of the filter press body 1 and the filter frame 2 are both existing technologies in the field and will not be repeated here.

[0028] A support rod 4 is horizontally arranged below the discharge port 5 of the filter press body 1, and both ends are fixedly connected to the frame 6; a cleaning mechanism 7 is arranged near the discharge port 5 and connected to the support rod 4, and is used to clean the material near the discharge port 5; a collecting mechanism 8 is arranged below the cleaning mechanism 7, and is used to collect the cleaned material.

[0029] The cleaning mechanism 7 includes a double-headed motor 71, which is longitudinally arranged on the support rod 4; a cleaning rod 72, which is arranged along the inner wall above the discharge port 5 and is transmission-connected to the upper output shaft 73 of the double-headed motor 71; and a scraper 74, which is arranged in the discharge port 5 and is transmission-connected to the upper output shaft 73.
