BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in the present application. For ordinary technicians in this field, it is easy to obtain other drawings based on these drawings without creative work.

[0014] Figure 1 Shown is a schematic structural diagram of a self-cleaning filter in a specific embodiment of the present invention. DETAILED DESCRIPTION

[0015] The following will describe the technical solutions in the embodiments of the present invention in detail in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Ginseng Figure 1 As shown, the self-cleaning filter in this embodiment includes a first flow channel 1, a second flow channel 2, a third flow channel 3 and a rotating shaft 4. The inlet and outlet of the first flow channel 1 are both enclosed with a porous plate 5, and the outer end surface of each porous plate 5 is covered with a mesh plate 9. The feed port of the second flow channel 2 covers part of the outer end surface of the mesh plate 9. One end of the rotating shaft 4 is fixedly connected to one of the porous plates 5 and extends into the first flow channel 1. A hollow cavity 401 is provided in the rotating shaft 4. One side of the cavity 401 passes through the rotating shaft 4 and is connected to the first flow channel 1. The third flow channel 3 passes through the rotating shaft 4 and is connected to the cavity 401. The end of the rotating shaft 4 away from the first flow channel 1 is connected to a rotating motor 402, and the outer end surface of the mesh plate 9 not covered by the discharge port of the second flow channel 2 is contacted and connected with a scraper 6.

[0017] Furthermore, one side of the cavity 401 passes through the rotating shaft 4 and extends into the first flow channel 1 to communicate with the first flow channel 1 .

[0018] Furthermore, the rotating shaft 4 is fixedly connected to the center of the porous plate 5 .

[0019] Furthermore, the rotating motor 402 is connected to the rotating shaft 4 via a coupling 403 .

[0020] In this technical solution, when the filter is filtering, impurities will be left on the outer end surface of the porous plate. The porous plate is driven to rotate by the rotating shaft, and the scraper will directly scrape off the impurities on the surface of the porous plate, avoiding the replacement of the filter screen, saving costs, and not affecting the continuous production of granulation, thereby improving efficiency.

[0021] In one embodiment, the unloading end of the scraper 6 is connected to a screw rod 7 , and the screw rod 7 is connected to a driving motor 701 .

[0022] In this technical solution, impurities scraped off by the scraper are effectively discharged in an orderly manner along the threads of the screw through the screw, which is orderly and efficient and convenient for centralized treatment.

[0023] In one embodiment, the scraper 6 is further connected to a telescopic cylinder 8 , and the telescopic cylinder 8 drives the scraper 6 to move away from and closer to the mesh plate 9 .

[0024] In this technical solution, the scraper is displaced and driven by a telescopic oil cylinder, so that the scraper can be cleaned conveniently.

[0025] Specific implementation principle:

[0026] The material flow enters the first flow channel from the second flow channel through the porous plate. The filtered material in the first flow channel is discharged from the third flow channel through the hollow cavity. When impurities remain on the porous plate, the rotation of the shaft drives the first flow channel and the porous plate to rotate as a whole. The scraper scrapes off the impurities on the porous plate and discharges slag along the screw driven by the motor.

[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0028] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
