[0024] The specific configuration and function of this embodiment are described in detail below. When filtering liquid, firstly, a pipe for passing liquid is connected to one side of the filter shell 1, and the liquid outlet pipe 2 is installed at the bottom of the filter shell 1. Then, liquid is introduced from one side of the filter shell 1, and the reduction motor 41 is started to indirectly drive the gear 1 31 and the fixed rod 32 to rotate. The fixed rod 32 rotates inside the filter shell 1, and at the same time drives the rotating cylinder 33 to rotate. The rotating cylinder 33 drives the support plate 35 and the membrane layer 36 to rotate. The liquid contacts one side of the membrane layer 36. After being filtered by the membrane layer 36, the liquid enters the support plate 35. 5, flows from the liquid through hole 34 to the inside of the rotating cylinder 33, the inside of the rotating cylinder 33 is communicated with the inside of the liquid outlet pipe 2, and then the filtered liquid flows from the inside of the rotating cylinder 33 to the inside of the liquid outlet pipe 2, and then flows out from the liquid outlet pipe 2. By setting the filtering mechanism 3, the membrane layer 36 presents a cylindrical shape. During the rolling process of the membrane layer 36, the sewage liquid is filtered, the surface area of the sewage contacting with the filter shell 1 is increased, a larger filtering area is achieved, the filtering efficiency is improved, and impurities such as suspended solids and microorganisms are effectively removed, the processing capacity is improved, and the risk of clogging is reduced. Example
[0025] like Figure 4 and Figure 5 As shown, the cleaning mechanism 4 includes a reduction motor 41, a gear 2 43 and a cleaning cotton roller 45. One side of the reduction motor 41 is fixedly connected to one side of the filter shell 1. The output end of the reduction motor 41 is drivingly connected with a rotating shaft 42. The rotating shaft 42 is installed through the interior of the gear 2 43. The outer wall of the gear 2 43 is meshed with the outer wall of the gear 1 31. One end of the rotating shaft 42 is fixedly installed with a limit disk 44. The rotating shaft 42 passes through the interior of the cleaning cotton roller 45. The outer wall of the cleaning cotton roller 45 is provided with a push-pull box 46. A scraper 47 is fixedly installed on one side of the push-pull box 46. One side of the scraper 47 is in close contact with the outer wall of the cleaning cotton roller 45. A fixing seat 48 is fixedly installed on the bottom of the push-pull box 46.
[0026] The effect achieved by the entire embodiment is that first, the push-pull box 46 is pushed upward, and the fixing seat 48 is fixed to the bottom of the filter shell 1 by means of bolts, and the reduction motor 41 is started to drive the rotating shaft 42 and the gear 2 43 to rotate, so that the gear 2 43 drives the gear 1 31 to rotate, and then drives the membrane layer 36 and the cleaning cotton roller 45 to rotate in opposite directions. Since the outer wall of the cleaning cotton roller 45 is in contact with the outer wall of the membrane layer 36, when the membrane layer 36 rotates and filters, impurities will be attached to the outer wall. When it rotates to one side of the cleaning cotton roller 45, the cleaning cotton roller 45 wipes off the impurities on the surface of the membrane layer 36. From the top perspective, the membrane layer 36 rotates clockwise and the cleaning cotton roller 45 rotates counterclockwise. By setting the cleaning mechanism 4, during the rotation of the cleaning cotton roller 45, the impurities on the outer wall are scraped off by the scraper 47 and fall into the push-pull box 46, and then the cleaning cotton roller 45 is cleaned. When the outer wall of the limit plate 44 contacts one side of the push-pull box 46, impurities will fall on the top of the limit plate 44. When the cleaning cotton roller 45 contacts the membrane layer 36, the impurities on the surface of the membrane layer 36 will adhere. Cleaning the surface of the membrane layer 36 can effectively remove dirt, microorganisms and biofilm attached to the membrane, restore the original water permeability of the membrane layer 36, and improve the filtration efficiency and processing capacity. The outer wall of the membrane layer 36 contacts the inner wall of the filter shell 1, and the rate at which liquid enters one side of the filter shell 1 is slower. The filtered sewage will flow downward from the rotating cylinder 33, and only a very small part of the moisture adhered to one side of the membrane layer 36 adheres to the outer wall of the cleaning cotton roller 45. After use, remove the fixing seat 48 and pull the push-pull box 46 downward. The position of the reduction motor 41 will not interfere with the movement of the push-pull box 46, and then clean the impurities on the outer wall of the limit plate 44 and the inner wall of the push-pull box 46.
[0027] The use method and working principle of the device are as follows: when filtering liquid, firstly, a liquid water pipe is connected to one side of the filter shell 1, and the liquid outlet pipe 2 is installed at the bottom of the filter shell 1, and then liquid is introduced from one side of the filter shell 1, and the push-pull box 46 is pushed upward, and the fixing seat 48 is fixed to the bottom of the filter shell 1 by means of bolts, and the reduction motor 41 is started to drive the rotating shaft 42 and the gear 2 43 to rotate, so that the gear 2 43 drives the gear 1 31 to rotate, and then drives the membrane layer 36 and the cleaning cotton roller 45 to rotate in opposite directions, and the fixing rod 32 rotates inside the filter shell 1, and at the same time drives the rotating cylinder 33 to rotate, and the rotating cylinder 33 drives the support plate 35 and the membrane layer 36 to rotate, and the liquid contacts one side of the membrane layer 36, and after being filtered by the membrane layer 36, the liquid enters between the support plates 35, and flows into the inside of the rotating cylinder 33 from the liquid through hole 34, and the inside of the rotating cylinder 33 is connected with the inside of the liquid outlet pipe 2, and then the filtered liquid flows from the inside of the rotating cylinder 33 to the inside of the liquid outlet pipe 2, and then flows out from the liquid outlet pipe 2, and is filtered by the filter. The outer wall of the cleaning cotton roller 45 is in contact with the outer wall of the film layer 36. When the film layer 36 rotates and filters, impurities will be attached to the outer wall. When it rotates to one side of the cleaning cotton roller 45, the cleaning cotton roller 45 wipes off the impurities on the surface of the film layer 36. From the top perspective, the film layer 36 rotates clockwise and the cleaning cotton roller 45 rotates counterclockwise. During the rotation of the cleaning cotton roller 45, the impurities on the outer wall are scraped off by the scraper 47 and fall into the push-pull box 46. Since the outer wall of the limit plate 44 and one side of the push-pull box 46 are in contact with each other, the outer wall of the limit plate 44 and one side of the push-pull box 46 are in contact with each other. The impurities will fall on the top of the limit plate 44, the outer wall of the membrane layer 36 will contact the inner wall of the filter shell 1, the rate of liquid entering one side of the filter shell 1 is slower, the filtered sewage will flow downward from the rotating cylinder 33, and only a very small part of the moisture adhering to one side of the membrane layer 36 will adhere to the outer wall of the cleaning cotton roller 45. After use, the fixing seat 48 is removed and the push-pull box 46 is pulled downward. The position of the reduction motor 41 will not interfere with the movement of the push-pull box 46, and then the impurities on the outer wall of the limit plate 44 and the inner wall of the push-pull box 46 are cleaned.
