Description

Technical Field

[0001] This utility model relates to the field of water-based coating processing technology, specifically to a water-based coating filtration device. Background Technology

[0002] All coatings that use water as a solvent or dispersion medium can be called water-based coatings. Based on the type of binder in the coating, water-based coatings are divided into two main categories: natural water-based coatings using natural substances or minerals (such as potassium silicate) and petrochemical water-based coatings using synthetic resins (such as acrylic resins). Water-based coatings include three types: water-soluble coatings, water-dilutable coatings, and water-dispersible coatings (latex coatings). Water-soluble coatings use water-soluble resins as film-forming agents, with polyvinyl alcohol and its various modified forms being representative examples. Other examples include water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins.

[0003] During the processing of water-based coatings, impurities within the coating necessitate filtration. Current filtration methods typically involve pouring the coating into a filter box and filtering it through an internal filter screen. However, the placement of the filter screen inside the box makes it inconvenient for workers to clean the trapped impurities. Therefore, there is an urgent need to design a water-based coating filtration device to address these issues. Utility Model Content

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown in the figure, an embodiment of the present invention provides a water-based coating filtration device, including a filter box 1, a lead screw 7 rotatably installed inside the filter box 1, a filter plate 6 provided at the bottom of the inner wall of the filter box 1, a groove 10 opened in the center of the filter plate 6, the filter plate 6 being sleeved around the lead screw 7 through the groove 10, a threaded sliding plate 11 fixedly installed between the inner walls of the groove 10, the threaded sliding plate 11 being threadedly connected to the lead screw 7, a first drive motor 9 fixedly installed on the lower side of the filter box 1, the output end of the first drive motor 9 being fixedly connected to the lower end of the lead screw 7, a limit plate 8 fixedly installed on the upper end of the lead screw 7, the limit plate 8 corresponding to the groove 10, a valve 13 provided on one side of the filter box 1, a discharge pipe 12 provided on one side of the valve 13, and four support legs 2 provided on the lower side of the filter box 1.

[0023] Specifically, in this embodiment, when filtering water-based coatings, the water-based coating is poured into the filter box 1, and then the first drive motor 9 is started, which drives the lead screw 7 to rotate. The rotation of the lead screw 7 drives the threaded slide plate 11 to move upward. The upward movement of the threaded slide plate 11 drives the filter plate 6 to move upward. Since both the filter plate 6 and the filter box 1 are square, and the filter plate 6 is attached to the inner wall of the filter box 1, the rotation of the lead screw 7 can guide and limit the threaded slide plate 11, thereby enabling the threaded slide plate 11 to move linearly. As the filter plate 6 moves upward from the bottom of the inner wall of the filter box 1, the filter plate 6 can intercept impurities in the water-based coating and cause the filter plate 6 to move the impurities upward. When the filter plate 6 moves to the upper end of the filter box 1, the impurities in the water-based coating can be intercepted and cleaned, and it is convenient for the staff to clean the impurities intercepted on the filter plate 6. After filtration, the water-based coating is discharged through the valve 13 and the discharge pipe 12.

[0024] This utility model provides a water-based coating filtration device. A cleaning mechanism 3 is provided on the upper side of the filter box 1, and a collection box 4 is provided on one side of the filter box 1. The cleaning mechanism 3 cooperates with the filter plate 6 and the collection box 4 respectively. The cleaning mechanism 3 includes a housing 14, a threaded rod 15, a sliding plate 16, and a cleaning scraper 17. There are two housings 14, two threaded rods 15, and two sliding plates 16. The two housings 14 are fixedly installed on the upper two sides of the filter box 1. The threaded rod 15 is rotatably installed between the housings 14. The sliding plate 16 is threadedly installed on the periphery of the threaded rod 15 and is slidably disposed inside the housing 14. The cleaning scraper 17 is fixedly installed on the upper end of the two sliding plates 16. A sprocket 18 is fixedly installed on one end of each of the two threaded rods 15. A chain 19 is sleeved on the periphery of the two sprockets 18. A second drive motor 20 is fixedly installed on one side of one of the housings 14. The output end of the second drive motor 20 is fixedly connected to one of the sprockets 18.

[0025] In another embodiment of this utility model, by starting the second drive motor 20, one of the sprockets 18 is driven to rotate. The rotation of the sprocket 18 can drive the other sprocket 18 to rotate through the chain 19, thereby making the two sprockets 18 rotate synchronously. The synchronous rotation of the two sprockets 18 can drive the two threaded rods 15 to rotate synchronously. The synchronous rotation of the two threaded rods 15 can drive the two sliding plates 16 to move synchronously along the inner wall of the outer shell 14. The synchronous movement of the two sliding plates 16 can drive the cleaning scraper 17 to move stably. The movement of the cleaning scraper 17 can scrape and clean the impurities on the filter plate 6, so that the cleaning scraper 17 scrapes the impurities into the collection box 4. Since the filter plate 6 will be flush with the upper end of the filter box 1 after it moves to the upper end of the filter box 1, and the limiting plate 8 will also be inserted into the slot 10, the cleaning scraper 17 will not cause any interference. In addition, the length of the outer shell 14 is longer than that of the filter box 1, so that the cleaning scraper 17 can move to the upper side of the collection box 4, so that the impurities are scraped into the collection box 4.

[0026] The present invention provides a water-based coating filtration device, wherein a drain outlet 21 is provided on the lower side of the collection box 4, and a slot 22 is provided on one side of the drain outlet 21. A sealing plate 23 is inserted and installed in the slot 22, and the sealing plate 23 corresponds to the drain outlet 21.

[0027] In another embodiment of this utility model, when cleaning the impurities in the collection box 4, one end of the sealing plate 23 is pulled to move the sealing plate 23 along the slot 22. After the sealing plate 23 is pulled out along the slot 22, the impurities are discharged through the drain port 21, thereby completing the cleaning of the impurities in the collection box 4. A snap-fit ​​component is provided between the sealing plate 23 and the slot 22. The snap-fit ​​component is an elastic bead, which can improve the stability of the sealing plate 23 after insertion.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
