Description

Technical Field

[0001] This application relates to the field of paint recycling technology, and more specifically, to a paint separation and recycling device. Background Technology

[0002] Water-based coatings are coatings that use water as a solvent or dispersion medium. They are a relatively new type of coating on the market. Water-based coatings include water-soluble coatings, water-dilutable coatings, water-dispersible coatings, etc. During the use of water-based coatings, external dust and impurities can easily fall into the coating. In order to avoid wasting unused coatings, coating recycling devices are often used to recycle and reuse the coatings.

[0003] A search revealed a public disclosure (announcement) number: CN217409946U, which discloses a solvent separation and recovery mechanism for water-based coatings. This mechanism includes a base, a filter box fixed to the top of the base, a discharge pipe connected to the bottom of the filter box, two mounting sleeves fixed inside the filter box, each sleeve containing a filter plate, a discharge box fixed to the top of the filter box, and a feeding hopper fixed to the top of the discharge box… This application can perform two-stage filtration of impurities in water-based coatings, effectively improving the purity of the water-based coatings. Simultaneously, the water-based coatings can be evenly sprayed onto the filter plates, resulting in more complete and thorough filtration. However, this application lacks an automatic cleaning mechanism for the filtered impurities, requiring manual cleaning of the top of the filter plates, which is not only time-consuming and labor-intensive but also increases the workload.

[0004] To address the aforementioned problems, this application provides a paint separation and recycling device. Utility Model Content

[0005] This application provides the following technical solution: a paint separation and recycling device, including a support base, a discharge assembly disposed on the top of the support base, and a discharge pipe disposed at the bottom of the housing. The top of the support base is fixedly connected to the housing. A first filter plate and a second filter plate are installed sequentially from top to bottom inside the housing. Two discharge holes are opened on the surface of the housing. A matching sealing plate is disposed inside the discharge holes. Multiple connecting rods are fixedly connected to the inner surface of the sealing plate. A cleaning brush is fixedly connected to the end of the connecting rod away from the sealing plate. A sealing plate is fixedly connected to the surface of the sealing plate. A fixing plate is fixedly connected to the right end face of the sealing plate. An electric push rod is fixedly connected to the right end face of the housing. The output end of the electric push rod is fixedly connected to the fixing plate.

[0006] Through the above technical solution, the electric push rod operates, causing the connecting rod to drive the cleaning brush to move, thereby sweeping and cleaning the impurities on the top of the first and second filter plates from back to front, and then discharging them through the discharge hole to the outside of the housing, thus realizing the automated cleaning of impurities.

[0007] Furthermore, the housing has two sliding holes, and a sliding rod is slidably connected inside the sliding holes.

[0008] Through the above technical solution, when the sealing plate moves, the sealing plate drives the sliding rod to move inside the sliding hole, thereby improving the stability of the sealing plate when it moves.

[0009] Furthermore, one end of the sliding rod is fixedly connected to the inner surface of the sealing plate, and the other end of the sliding rod extends to the rear of the housing.

[0010] Furthermore, a rubber pad is provided on the outer side of the sealing plate, and the rubber pad is fixedly connected to the inner surface of the sealing plate.

[0011] The above technical solution improves the sealing performance between the sealing plate and the housing by using rubber gaskets.

[0012] Furthermore, both the first filter plate and the second filter plate are composed of a filter screen, a first mesh frame, and a second mesh frame. The first mesh frame is fixedly connected between two adjacent filter screens, one side of the second mesh frame is fixedly connected to the inner wall of the housing, and the other side of the second mesh frame is fixedly connected to the filter screen.

[0013] The above technical solution avoids the accumulation of filtered impurities on the top of the filter screen, thus preventing them from affecting the filtration effect.

[0014] Furthermore, the pore size of the first filter plate is larger than that of the second filter plate, and the filter screen is arranged in an inverted "V" shape.

[0015] Through the above technical solution, the impurities filtered out by the filter screen can slide down the inclined surfaces on both sides of the top of the filter screen into the interior of the first or second mesh frame, thereby collecting the impurities using the first or second mesh frame.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] 1. This application controls the operation of an electric push rod to move a fixed plate. The movement of the fixed plate causes the sealing plate, connecting rod, and cleaning brush to move forward. The forward movement of the sealing plate opens the discharge hole. The connecting rod drives the cleaning brush to move, which can sweep and clean the impurities on the top of the first and second filter plates from back to front. Then, the impurities are discharged to the outside of the housing through the discharge hole, thus eliminating the need for manual operation and realizing automatic cleaning of impurities.

[0018] 2. The filter screen with an inverted "V" shape structure facilitates the sliding of filtered impurities through the sloping surfaces on both sides of the top of the filter screen into the interior of the first or second mesh frame, thereby utilizing the first or second mesh frame to collect the impurities and preventing the filtered impurities from accumulating on the top of the filter screen, which would affect the filtration effect.

[0027] Example:

[0028] This application discloses a paint separation and recycling device. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 The device includes a support base 1, a discharge assembly 5 set on the top of the support base 1, and a discharge pipe 10 set on the bottom of the housing 2. The bottom end of the discharge pipe 10 passes through the middle of the support base 1 and extends to the bottom of the support base 1. The discharge assembly 5 is a prior art, and its structure and working principle are based on a water-based coating solvent separation and recovery mechanism with publication (announcement) number CN217409946U. It will not be described in detail here. The top of the support base 1 is fixedly connected to the housing 2. A glass plate is installed on the back side of the housing 2. The glass plate allows for easy observation of the interior of the housing 2. The interior of the housing 2 is installed with a first filter plate 9 and a second filter plate 14 from top to bottom. The cooperation of the first filter plate 9 and the second filter plate 14 achieves two-stage filtration of the water-based coating, which effectively improves the purity of the water-based coating. Two discharge holes 8 are opened on the surface of the housing 2. A matching sealing plate 12 is set inside the discharge hole 8. Multiple connecting rods 11 are fixedly connected to the inner surface of the sealing plate 12.

[0029] A cleaning brush 13 is fixedly connected to the end of the connecting rod 11 away from the sealing plate 12. The height of the cleaning brush 13 is lower than the height of the inner top wall of the discharge hole 8. The cleaning brush 13 is set on the inner wall of the housing 2 on the side surface away from the discharge hole 8. A sealing plate 4 is fixedly connected to the surface of the sealing plate 12. A fixing plate 3 is fixedly connected to the right end face of the sealing plate 4. An electric push rod 15 is fixedly connected to the right end face of the housing 2. The output end of the electric push rod 15 is fixedly connected to the fixing plate 3. When the electric push rod 15 works, it drives the fixing plate 3 to move. The movement of the fixing plate 3 drives the sealing plate 12, the connecting rod 11 and the cleaning brush 13 to move forward. The forward movement of the sealing plate 12 opens the discharge hole 8. The connecting rod 11 drives the cleaning brush 13 to move, which can sweep and clean the impurities on the top of the first filter plate 9 and the second filter plate 14 from back to front, and then discharge them to the outside of the housing 2 through the discharge hole 8.

[0030] Please see Figure 1 The housing 2 has two sliding holes 7. A sliding rod 6 is slidably connected inside the sliding holes 7. One end of the sliding rod 6 is fixedly connected to the inner surface of the sealing plate 4, and the other end of the sliding rod 6 extends to the rear of the housing 2. The cooperation between the sliding rod 6 and the sliding holes 7 limits the sealing plate 4. When the sealing plate 4 moves, the sealing plate 4 drives the sliding rod 6 to move inside the sliding holes 7, thereby improving the stability of the sealing plate 4 when it moves. A rubber pad (not shown in the figure) is provided on the outer side of the sealing plate 12. The rubber pad is fixedly connected to the inner surface of the sealing plate 4. The rubber pad improves the sealing performance between the sealing plate 4 and the housing 2.

[0031] Please see Figure 3The first filter plate 9 and the second filter plate 14 are each composed of five filter screens, four first mesh frames, and two second mesh frames. Multiple cleaning brushes 13 are located inside the first and second mesh frames. The inner bottom walls of the first and second mesh frames are at the same level as the inner bottom wall of the discharge hole 8. The first mesh frame is fixedly connected between two adjacent filter screens. One side of the second mesh frame is fixedly connected to the inner wall of the housing 2, while the other side of the second mesh frame is fixedly connected to the filter screen. The aperture of the first filter plate 9 is larger than that of the second filter plate 14. The filter screen is set in an inverted "V" shape. This design facilitates the impurities filtered by the filter screen to slide down the inclined surfaces on both sides of the top of the filter screen to the inside of the first or second mesh frame, thereby using the first or second mesh frame to collect the impurities and avoid the accumulation of filtered impurities on the top of the filter screen, which would affect the filtration effect.

[0032] The implementation principle of this application embodiment is as follows: the discharge assembly 5 discharges the paint into the interior of the housing 2, and the cooperation of the first filter plate 9 and the second filter plate 14 achieves two-stage filtration of the water-based paint. The impurities filtered down by the filter screen slide down the inclined surfaces on both sides of the top of the filter screen to the interior of the first or second mesh frame, thereby collecting the impurities using the first or second mesh frame and preventing the filtered impurities from accumulating on the top of the filter screen. When it is necessary to clean the impurities;

[0033] The electric push rod 15 is controlled to move the fixed plate 3. The movement of the fixed plate 3 causes the sealing plate 12, the connecting rod 11 and the cleaning brush 13 to move forward. The forward movement of the sealing plate 12 opens the discharge hole 8. The connecting rod 11 drives the cleaning brush 13 to move, which can sweep and clean the impurities on the top of the first filter plate 9 and the second filter plate 14 from back to front, and then discharge them to the outside of the housing 2 through the discharge hole 8.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
