DETAILED DESCRIPTION

[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Example

[0027] Figure 1-Figure 6 As an embodiment of the utility model, a grease filtering device is proposed, including a base plate 1, a roller is installed at the bottom of the base plate 1, a storage barrel 2 and a filter tank 3 are installed on the top of the base plate 1, a conveying pipe 4 is connected between the bottom of the storage barrel 2 and the filter tank 3, and a filtering component 5 is installed inside the storage barrel 2 and the filter tank 3. When in use, the grease to be filtered is first poured into the storage barrel 2, and then the grease inside the storage barrel 2 is pushed to move toward the filter tank 3. In this process, the filtering component 5 filters the grease, and finally the filtered grease stays in the filter tank 3. When it needs to be discharged, the filtered grease is discharged from the filter tank 3, which can meet the demand for filtering the grease. When all the grease in the storage barrel 2 enters the filter tank 3 and is filtered, the staff cleans the impurities in the storage barrel 2 and the filter tank 3.

[0028] The filter assembly 5 includes a pressing plate 51 installed inside the storage barrel 2 and a filter screen 52 installed inside the filter tank 3. A sedimentation tank is provided at the bottom of the storage barrel 2. The sedimentation tank includes a spherical protrusion in the middle of the storage barrel 2 and a lower groove on the outer ring of the spherical protrusion. The bottom of the pressing plate 51 is embedded in the sedimentation tank, and the delivery pipe 4 passes through the spherical protrusion. The inner wall of the filter tank 3 is fixedly connected with a plurality of support blocks 55 with curved tops, and an elastic plate 53 is fixedly connected between the support blocks 55 and the filter screen 52. A scraper assembly 54 is installed on the top of the filter screen 52. When in use, the pressing plate 51 is first moved upward to the outside of the storage barrel 2, and then the grease to be filtered is poured into the storage barrel 2. Some impurities in the grease first settle at the bottom of the sedimentation tank, and then the pressing plate 51 is pushed down. After entering the storage barrel 2, the pressing plate 51 continues to descend to press the grease inside the storage barrel 2 into the filter tank 3.

[0029] When the grease is pushed, it flows toward the outer circle along the spherical protrusion in the middle of the sedimentation tank, and pushes the impurities settled at the bottom of the sedimentation tank toward the outer circle of the sedimentation tank, reducing the possibility that the impurities stay in the middle of the sedimentation tank and are brought into the conveying pipe 4 by the grease. After the grease enters the interior of the filter tank 3, it impacts the filter screen 52, and pushes the filter screen 52 downward. The grease passes through the filter screen 52, and the impurities in the grease are blocked by the filter screen 52 and stay on the upper surface of the filter screen 52. When the filter screen 52 descends, it squeezes and bends the elastic plate 53, and controls the intermittent descent of the pressing plate 51. When the pressing plate 51 does not descend, the grease stops entering the interior of the filter tank 3, and the filter screen 52 is no longer squeezed downward by the grease. The plate 53 pushes the filter 52 to rise. During the process of the filter 52 being raised and lowered, the scraper assembly 54 scrapes the upper surface of the filter 52, pushing the impurities attached to the surface of the filter 52 to the edge of the filter 52, and can first use sedimentation to reduce a part of the impurities in the grease, reduce the amount of impurities moved to the filter 52, and at the same time clean the impurities on the surface of the filter 52 during the grease filtering process. Combining sedimentation with cleaning of impurities on the filter 52 can prevent impurities from clogging the filter 52 and reduce the frequency of cleaning the filter 52. At the same time, there is no need to stop the grease filtering process when cleaning the filter 52, thereby improving the grease filtering speed.

[0030] The scraper assembly 54 includes a scraper 541 slidably connected to the top of the filter screen 52. A long rod 542 is rotatably connected between the top of the scraper 541 and the inner wall of the filter tank 3. When the grease pushes the filter screen 52 down, the elastic plate 53 is squeezed and bent by the filter screen 52, and the scraper 541 descends with the filter screen 52 to Figure 4 For example, it is pulled by the long rod 542 to move to the right along the surface of the filter screen 52 until the pressing plate 51 stops pushing the grease in the storage barrel 2 downward, and the grease no longer enters the filter tank 3. After that, the filter screen 52 is no longer squeezed downward, and the elastic plate 53 pushes the filter screen 52 to rise. The scraper 541 is pushed up by the filter screen 52 and is pushed to the left along the filter screen 52 by the long rod 542, pushing the impurities attached to the upper surface of the filter screen 52 to the left side of the filter screen 52 to prevent the impurities from clogging the filter screen 52 and reducing the speed of the grease passing through the filter screen 52. The squeezing force on the filter screen 52 during grease filtering can drive the scraper 541 to automatically clean the filter screen 52, thereby reducing the difficulty of cleaning impurities on the surface of the filter screen 52, and there is no need to stop the grease filtering process to clean the filter screen 52.

[0031] The scraper 541 includes a transverse frame 5411 rotatably connected to the long rod 542, and two sliders 5412 are slidably connected to the inner wall of the transverse frame 5411, and a spring 5413 is fixedly connected between the two sliders 5412. When in use, the spring 5413 pushes the slider 5412 to move in a direction away from the transverse frame 5411 until the end of the slider 5412 away from the transverse frame 5411 is pressed against the inner wall of the filter tank 3. When the transverse frame 5411 moves along the filter screen 52, the transverse frame 5411 and the slider 5412 scrape off the impurities on the filter screen 52. At the same time, the inner wall of the filter tank 3 squeezes the slider 5412 into the interior of the transverse frame 5411, so that the scraper 541 can adjust the length, which is convenient for cleaning positions of different widths of the filter screen 52.

[0032] A bracket 6 is fixedly connected to the top of the bottom plate 1, and a hydraulic cylinder 7 is installed on the top of the bracket 6. The output end of the hydraulic cylinder 7 movably passes through the bracket 6, and a pressing plate 51 is installed at the output end of the hydraulic cylinder 7. When the grease in the storage barrel 2 needs to be pushed into the filter tank 3, the hydraulic cylinder 7 pushes the pressing plate 51 down. When all the grease in the storage barrel 2 is pushed into the filter tank 3 and the filtration is completed, the hydraulic cylinder 7 drives the pressing plate 51 to rise until the pressing plate 51 moves to the outside of the storage barrel 2, and then the staff cleans the impurities in the storage barrel 2 from the opening at the top of the storage barrel 2.

[0033] A storage frame 8 is fixedly connected to one side of the inner wall of the filter tank 3, and the inner wall of the storage frame 8 is provided with a scraper 9 with one end movably extending to the outside thereof, and a through groove is opened on one side of the scraper 9, and a traction rope 10 is fixedly connected between the scraper 9 and the storage frame 8, and a sealing cover 11 is rotatably connected to the top of the filter tank 3, and a handle 12 is fixedly connected to the top of the sealing cover 11. When all the grease has passed through the filter screen 52, the staff holds the handle 12 to open the sealing cover 11, and then takes out the scraper 9 from the inside of the storage frame 8, shovels together the impurities on the surface of the filter screen 52 pushed to the edge by the scraper 541, and then shovels the impurities on the surface of the filter screen 52 to the outside of the filter tank 3, and finally puts the scraper 9 back into the storage frame 8, and covers the sealing cover 11 again, so as to facilitate the collection of impurities on the surface of the filter screen 52 and reduce the difficulty of cleaning impurities attached to the filter screen 52.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
