Description

Technical Field

[0001] The utility model relates to the technical field of oil filter machines, in particular to a feed filtering structure of an oil filter machine. Background Art

[0002] The feed filter structure of the oil filter is a crucial component of the oil filter. Its design is directly related to the working efficiency of the oil filter, the quality of the oil and the operating stability of the equipment. In the oil processing process, the raw oil often contains various impurities, such as particulate matter. If these impurities are not effectively filtered, they will not only affect the normal operation of the oil filter, but also may cause damage to the subsequent equipment using the oil.

[0003] The Chinese patent discloses: a feed filtration structure of an oil filter machine, patent application number: 202123425314.0, which "includes a filter bucket and a filter cartridge, the top of the filter bucket is trumpet-shaped, and the bottom end is connected to the top of the filter cartridge; a cone bucket is installed in the filter bucket, and a filter screen is installed at the bottom of the cone bucket; a progressive filter disc structure is installed in the middle of the filter cartridge; the progressive filter disc structure includes a plurality of filter discs, which are sequentially installed in the filter cartridge, and their diameters gradually increase from top to bottom to form a diffuse filtering structure; when the utility model is working, the oil enters the filter cartridge through the filter bucket, and is first preliminarily filtered through the filter screen. The filtered oil falls into the progressive filter disc structure, and is quickly filtered through a plurality of filter discs before being discharged to realize feed filtration."

[0004] Although the device can achieve rapid flow filtration through the filter rod, diagonal guide rod and filter plate, thereby improving the filtration efficiency and filtration effect; in addition, a dispersion seat is designed in the filter bucket to fix the filter rod and play a role in dispersion and diversion, but the patent does not provide a cleaning structure, resulting in the inability to clean the filter net in time. Therefore, after the filter net filters the impurities, the impurities will adhere to the filter net. After long-term use, it is easy to cause the filter net to be blocked and the filtration efficiency to decrease. Cleaning is inconvenient, time-consuming and labor-intensive, and inconvenient to use. Utility Model Content

[0005] In view of this, the purpose of the utility model is to propose a feed filter structure for an oil filter machine to solve the problem that the filter cannot be cleaned in time. Therefore, the impurities will adhere to the filter after filtering the impurities. After long-term use, it is easy to cause the filter to be blocked and the filtration efficiency to decrease, which is inconvenient to clean.

[0006] Based on the above purpose, the utility model provides a feed filtering structure of an oil filter, including an oil filter body, the top of which is fixedly connected to a feed pipe, an impurity filtering and cleaning component is arranged inside the feed pipe, and the impurity filtering and cleaning component is used to clean impurities after oil filtration.

[0007] Preferably, the impurity filtering and cleaning assembly includes an open fixing plate, which is fixedly connected to the inner wall of the feed pipe, and the bottom of the open fixing plate is fixedly connected to a filter cylinder, and a support plate is fixedly connected between the top of the inner wall of the filter cylinder, the bottom of the support plate is rotatably connected to a rotating rod, and the outer wall of the rotating rod is fixedly connected to a scraper, one end of the rotating rod is rotatably connected to the bottom of the filter cylinder, and the other end of the rotating rod passes through the top of the support plate and is fixedly connected to a first cone wheel, the side wall of the feed pipe is rotatably connected to a rotating rod, and one end of the rotating rod passes through the inner wall of the feed pipe and is fixedly connected to a second cone wheel, and the second cone wheel and the first cone wheel are meshed with each other.

[0008] Preferably, a cleaning hole is opened at the bottom of the filter mesh cylinder, and a support slide is fixedly connected to both sides of the bottom of the filter mesh cylinder near the cleaning hole, one end of the support slide is fixedly connected to the inner wall of the feed pipe, and an impurity collection box is arranged inside the support slide.

[0009] Preferably, a filter screen is fixedly connected to the interior of the impurity collection box.

[0010] Preferably, an oil scraper plate is fixedly connected between the supporting slide plates, and the top of the oil scraper plate fits with the bottom of the impurity collection box.

[0015] Preferably, a side of the scraper close to the inner wall of the filter screen cylinder is in contact with the inner wall of the filter screen cylinder.

[0016] Beneficial effects of the utility model:

[0017] The oil is transported into the oil filter body through the feed pipe, and when the oil passes through the filter cylinder and the filter screen and is filtered through the filter cylinder and the filter screen, impurities are attached to the bottom and inner wall of the filter cylinder after filtering. By rotating the rotating rod, the rotating rod drives the second cone wheel to rotate, and the second cone wheel drives the first cone wheel to rotate, and then the first cone wheel drives the rotating rod and the scraper to rotate. When the scraper rotates, it will scrape off the impurities attached to the inner wall and bottom of the filter cylinder. When the scraper rotates to the top of the cleaning through hole, the impurities will fall into the impurity collection box, and then the impurity collection box can be pulled out of the feed pipe, so that the impurities in the filter cylinder and the filter screen can be easily cleaned in time to avoid clogging of the filter cylinder. At the same time, the filtration efficiency is guaranteed, time and effort are saved, and cleaning is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
