High-pressure filter structure

Abstract

The utility model discloses a high-pressure filter structure, which relates to the technical field of high-pressure filters and comprises a filter cylinder, and a positioning plate is fixedly mounted in the filter cylinder. The filter disclosed by the utility model has the beneficial effects that when water flow is filtered, the valve on the outer side of the blow-off pipe can be opened, and then the water flow in the filter cylinder body can pass through the outer side to carry out back washing on the filter cylinder body, so that impurities filtered in the filter cylinder body enter the connecting pipe and the rotating pipe through the blow-off connector and are finally discharged through the blow-off pipe; in addition, after sewage discharge in one filter cylinder is completed, a servo motor is started to drive a transmission shaft and a driving bevel gear to rotate, the driving bevel gear is meshed with a driven bevel gear to drive a rotating pipe and a connecting pipe, and a sewage discharge connector rotates, so that the sewage discharge connector rotates to the position below a flow guide hole below the other filter cylinder to be in butt joint with the flow guide hole. Therefore, impurities filtered by the filter cartridge can be discharged from the filter cartridge body, and shutdown for pollution discharge after filtration is completed is not needed.

Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure filters, in particular to a high-pressure filter structure. Background Art

[0002] When the filter filters water, in order to increase the filtration speed, high-pressure water is often used. The high-pressure water to be filtered enters from the water inlet and flows through the filter, and then enters the pipeline required by the user through the water outlet for process circulation. The particulate impurities in the water are trapped inside the filter.

[0003] According to a high-pressure filter structure with application number 201620930708.1, the high-pressure filter structure, the supporting structure and the annular pressure plate firmly fix the filter screen in the cylinder body, can withstand the impact of high-pressure water flow, the structure is more stable, and the high-pressure water flow can be efficiently filtered; the annular pressure plate used to support the filter screen and the supporting structure used to support the annular pressure plate are both detachable, which is convenient for loading and unloading and improves the cleaning efficiency; the height of the water inlet on the cylinder body is lower than the height of the water outlet, which reduces the impact of the high-pressure water flow on the cylinder body and can efficiently filter the high-pressure water flow.

[0004] However, the above-mentioned high-pressure filter structure has certain shortcomings. This structure can only discharge the impurities remaining in the filtration after the water flow is filtered and the machine is shut down. During the filtration process, the impurities in the water will remain in the filter. When there are too many filtered impurities, the filter will be blocked, which will affect the filtration efficiency of the water flow and cause impurities to pass through the filter, affecting the filtration effect. For this reason, we propose a high-pressure filter structure. Utility Model Content
