Description

Technical Field

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

[0002] The double-membrane process is a relatively common and mature process in coal chemical production. In the double-membrane process, the influent water at the front end of ultrafiltration needs to control suspended solids and colloids, and other indicators need to be controlled. Generally, the influent water quality is poor, making it difficult to self-clean during the self-cleaning stage. This requires the assistance of pressurized spraying of reagents to improve the cleaning effect. After the spraying is completed, a scraper is needed to scrape away impurities for higher cleanliness. The existing scraper is composed of a connecting rod and a plate. During scraping, the connecting rod is rotated to drive the plate to rotate, thereby scraping away impurities. Although it can complete the above functions, there are also problems with the scraper's overly simple function, which makes it impossible to collect impurities after scraping. At the same time, after long-term use, the scraper's adhesion to the wall is reduced, resulting in poor scraping effect.

[0003] A search revealed patent document CN218873135U, which discloses a self-cleaning filter scraper. The scraper comprises a support shaft, a spring-loaded telescopic rod, a scraper, a pressure pipe, a nozzle, a bearing, a collection tank, a water inlet, and a filter screen. This utility model addresses the problem of existing scrapers being too limited in functionality by providing a self-cleaning filter scraper.

[0004] The scraper of the self-cleaning filter device of the utility model is adjusted by the deformation of the spring telescopic rod. However, the pressure of the spring in the spring telescopic rod cannot be adjusted, resulting in the elastic force provided by the spring being insufficient to keep the scraper in close and continuous contact with the scraping surface. This is especially true when there are stubborn attachments on the scraping surface or when the surface is tilted or irregular. This will greatly reduce the cleaning effect, or even completely prevent effective cleaning in some areas. Moreover, in the face of different scraping surfaces and different cleaning tasks, the elastic telescopic rod without a pressurization function may have difficulty adjusting its force to adapt to different situations. For example, when a stronger cleaning force is needed, the demand may not be met due to the fixed spring force; and when a smaller force is needed to avoid damaging the scraping surface, damage may be caused by excessive elastic force. Therefore, a high-precision self-cleaning filter device is proposed to solve the above-mentioned problems. Utility Model Content
