[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 5 As shown, a filtration device for water-based coating production includes a filter frame 1, an L-shaped plate 2 fixedly connected to the upper side of the filter frame 1, a drive motor 3 fixedly connected to the upper side of the L-shaped plate 2, a cleaning rod 4 fixedly connected to the output end of the drive motor 3, a scraper 5 fixedly connected to one side of the cleaning rod 4, a filter screen 6 fixedly connected to the inner wall of the filter frame 1, a discharge port 7 opened on the upper side of the filter screen 6, and an outlet hopper 8 that fits against the scraper 5 fixedly connected to the inner wall of the discharge port 7.

[0025] like Figure 2 and Figure 5 As shown, a square insert frame 15 is fixedly connected to one side of the filter frame 1. A collection box 16 is slidably fitted on the inner wall of the square insert frame 15. By inserting the collection box 16 into the inside of the square insert frame 15, one side of the square insert frame 15 fits against the filter frame 1, so that the impurities discharged from the outlet 17 can be received, which is convenient for subsequent unified processing.

[0026] like Figure 1As shown, the filter frame 1 is provided with multiple support legs 21 on its lower side, and each of the multiple support legs 21 is provided with an anti-slip pad 22 on its lower side. The support legs 21 can support the filter frame 1, and the anti-slip pad 22 can contact the ground to reduce damage to the ground and reduce the noise generated by the ground during operation.

[0027] like Figure 1 As shown, two reinforcing ribs 23 are fixedly connected to the upper side of the filter frame 1. One end of the two reinforcing ribs 23 is fixed to both sides of the L-shaped plate 2. The stability of the L-shaped plate 2 can be increased by connecting the reinforcing ribs 23 to the L-shaped plate 2.

[0028] like Figure 2 As shown, a discharge port 17 is provided on one side of the filter frame 1. The discharge port 17 and the outlet 8 are matched. The lower side of the inner wall of the outlet 8 is set in an inclined shape. When the scraper 5 scrapes the impurities on the filter screen 6, they pass through the interior of the outlet 8 and flow from the inclined position. Then, they are introduced into the interior of the collection box 16 through the discharge port 17 to achieve subsequent collection.

[0029] The inner wall of the scraper 5 is provided with a blowing groove 9. An air pump 10 is fixedly connected to the upper side of the scraper 5. The output end of the air pump 10 extends into the interior of the blowing groove 9. A heating box 11 is provided on the upper side of the scraper 5. A heating wire 12 is fixedly connected to the inner wall of the heating box 11. An air inlet 13 is provided on the upper side of the heating box 11. A trigger assembly 14 is provided between the scraper 5 and the L-shaped plate 2.

[0030] like Figure 3 As shown, the trigger assembly 14 includes a push switch 141 fixedly connected to the upper side of the scraper 5, a fixing ring 142 fixedly connected to the upper side of the inner wall of the L-shaped plate 2, and a notch 143 fixedly connected to the fixing ring 142 and cooperating with the push switch 141. The push switch 141, the heating wire 12, and the air pump 10 are electrically connected. When the drive motor 3 drives the scraper 5 to rotate, the push switch 141 will rotate accordingly. Once the push switch 141 is separated from the notch 143, the air pump 10 and the heating wire 12 can be automatically turned on. Thus, when the drive motor 3 is started, the air pump 10 and the heating wire 12 will be automatically turned on, improving the degree of automation in the later stage. There is no need to control the air pump 10 and the heating wire 12 separately, saving manpower. The push switch 141 can be connected to the external power supply by rotating it or assembled with a power supply that rotates with it, without affecting its power supply.

[0031] like Figure 3As shown, a dustproof frame 18 is fixedly connected to the inner wall of the air inlet 13, and a sealing gasket 19 is fixedly connected to the upper side of the dustproof frame 18. The sealing gasket 19 and the L-shaped plate 2 are in contact. When not in use, the dustproof frame 18 can be sealed inside by fitting with the L-shaped plate 2, thus preventing a large amount of dust from entering the dustproof frame 18.

[0032] like Figure 3 As shown, a dustproof net 20 is fixedly connected to the inner wall of the dustproof frame 18. When the dustproof frame 18 is in the process of air intake, the dustproof net 20 can filter the dust inside the air intake and improve the cleanliness of the gas sprayed from the blower slot 9.

[0033] The implementation principle of this application is as follows: When in use, the filter frame 1 is placed in the corresponding position and connected to the corresponding pipe on the lower side. Then, water-based paint is poured into the filter frame 1, and the filter screen 6 can filter the paint, leaving the filtered impurities on the upper side of the filter screen 6. After a certain period of use, the drive motor 3 can drive the scraper 5 to rotate, so that the impurities on the upper side of the filter screen 6 are scraped off by the scraper 5. When the impurities move to the upper side of the discharge port 7 and the discharge hopper 8, the impurities will fall into the inner wall of the discharge hopper 8 for discharge. During filtration, the scraper 5 is located on the upper side of the discharge hopper 8, which can seal the upper side of the discharge hopper 8.

[0034] While the scraper 5 is rotating, the air pump 10 can be activated to draw air into the heating box 11. The air is heated by the heating wire 12, and a certain amount of hot air is discharged into the blowing slot 9. The hot air can quickly transfer heat to the paint, making the molecular chains of the paint active, reducing its hardness and viscosity. The softened paint is then blown down and separated, achieving simultaneous cleaning of the surface and gaps of the filter screen 6, thus improving its cleaning effect.

[0035] When the drive motor 3 drives the scraper 5 to rotate, its push switch 141 will rotate accordingly. Once the push switch 141 is separated from the notch 143, the retaining ring 142 will squeeze the push switch 141, thereby enabling the air pump 10 and heating wire 12 to be automatically turned on when the drive motor 3 is started, improving the degree of automation in the later stage, eliminating the need to control the air pump 10 and heating wire 12 separately, and saving manpower.
