Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a segmented flush-free bag filter. Background Art

[0002] The bag filter is a novel filtration system which generally adopts the method of feeding liquid into the filter bag from the upper end, and providing a filter basket support outside the filter bag, so that the clear liquid flows out of the filter bag to the outlet at the lower end of the filter, and the filter residue is trapped in the filter bag. After a period of use, a lot of solid filter residue will be trapped in the filter bag. Therefore, the filter needs to be opened manually at regular intervals, and dozens of bolts need to be unscrewed when opening the filter, which not only has low operation efficiency but also increases the labor intensity of workers. After opening the filter, the filter bag needs to be manually taken out for cleaning or replacement, and then the filter bag is put back into the filter, which not only requires regular and regular manual maintenance, but also has troublesome and laborious disassembly and maintenance process. In addition, the existing bag filter has the following disadvantages during use: the filter bag needs to be manually cleaned, which increases the consumption of human resources; manual cleaning can easily cause the filter bag to be damaged, increasing the probability of filter bag damage; frequent disassembly of the filter causes the filter life to be shortened, affecting production capacity; the residue in the filter bag has a large moisture content, which is not only inconvenient to collect, but also leads to waste of water resources and increases production cost.

[0003] The Chinese utility model patent application number: 202323082475.3 discloses a self-cleaning bag filter, comprising a filter body, the bottom of the filter body is fixedly connected to a sewage pipe, the surface of the sewage pipe is provided with an opening and closing mechanism, the interior of the filter body is fixedly connected to a support plate, one side of the filter body is provided with a reciprocating mechanism, the reciprocating mechanism includes a control box installed on one side of the filter body, and the inner wall of the control box is fixedly connected to a control motor. However, the filtering structure of this self-cleaning bag filter is relatively complex, and it realizes the self-cleaning function of the filter by cooperating with multiple groups of components. If a component is damaged, the cleaning structure as a whole will be scrapped, affecting the self-cleaning function of the filter. It has a high rate of wear and tear and a short service life, which is not conducive to its popularization and use. Utility Model Content

[0032] Working principle:

[0033] When the raw water needs to be filtered, the filter body is arranged in the water treatment system through the supporting mechanism. In the initial state, the impurity removal net cylinder 12 is located inside the filter cylinder 10, and the raw water enters the filter body through the water inlet 7. The dry residue and impurities in the raw water remain in the impurity removal net cylinder 12, and the filter cylinder 10 and the filter bag 11 perform double filtration on the raw water. The filtered water is discharged from the filter through the guide shell 6 along the water outlet electric valve 8. After the filtration is completed, the sliding assembly drives the impurity removal net cylinder 12 to rise so that the impurity removal net cylinder 12 is separated from the filter cylinder 10, thereby taking the impurities out of the filter cylinder 10 after the filtration is completed, avoiding impurities remaining in the filter cylinder 10, and then taking out and replacing the impurity removal net cylinder 12 through the filter inspection plate 5 on the side of the filter body. After the replacement is completed, the sliding assembly drives the impurity removal net cylinder 12 to move to the inside of the filter cylinder 10 to wait for the next filtration operation. There is no need to rinse the filter cylinder 10 to meet the filtration needs of the raw water.

[0034] The beneficial effects of the utility model are that the structure is simple. The filter body is composed of a segmented shell structure. The support mechanism can provide stable installation support for the segmented filter structure. The filtering mechanism and the impurity removal mechanism are coordinated to automatically collect slag and remove impurities from the filter cartridge after filtration. There is no need to flush and maintain the filter cartridge, which can ensure the filtering effect of the filter cartridge and the filter bag and extend the service life of the filter.

However, the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
