Description

Technical Field

[0001] The utility model relates to the technical field of water-based paint filtering, in particular to a water-based paint filtering device that is easy to disassemble, assemble and clean. Background Art

[0002] Water-based paint is a kind of paint. Because water-based paint has little pollution to the environment during production and use, it has a very broad market prospect. Water-based paint is a paint that uses water as a diluent and does not contain organic solvents. Its paint film is plump, crystal clear, flexible, and has the characteristics of water resistance, wear resistance, aging resistance, yellowing resistance, fast drying and easy use. The production process of water-based paint includes mixing its various components by stirring so that the water-based paint can be mixed evenly.

[0003] However, during the stirring process of water-based paint, there may be some raw materials or debris that are difficult to dilute and decompose, which will affect the use of the water-based paint. Therefore, the water-based paint needs to be filtered because water-based paint also has a viscous structure.

[0004] For example, a water-based paint filtering device disclosed in Chinese patent CN217645954U utilizes the internal structure of the filter box. The poured water-based paint will first pass through the filter screen and then through the full filter screen, so that the water-based paint can be filtered in multiple layers. The water-based paint can be reduced and the sticky lumps can be reduced in coordination with the internal temperature, so that the water-based paint can be diluted more evenly. The engine is started to drive the center control rod, and the center control rod drives the filter screen, the full filter screen and the scraper, so that the internal water-based paint is stirred and filtered. At the same time, the scraper can also be used to push the residual water-based paint into the paint leakage hole when releasing the water-based paint, to ensure that no residual paint is left at the bottom of the filter box, and to accelerate the filtration at the same time.

[0005] However, the filter screen in the filter device is fixed to the device, so it is not convenient to repair the filter screen when it is damaged.

[0006] For this reason we urgently need to provide a kind of water-based paint filtering device that is easy to disassemble and clean. Utility Model Content

[0007] The utility model aims to provide a water-based paint filtering device which is easy to disassemble and clean, so as to solve the problem that the filter screen in the filtering device proposed in the above background technology is fixed to the device, so that it is not convenient to replace the filter screen when it is damaged.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water-based paint filtering device that is easy to disassemble and clean, comprising a filter tank and a tank cover, the tank cover is connected to the upper end of the filter tank, a feed pipe is fixedly connected to the middle position of the inner left end of the tank cover, a discharge pipe is fixedly connected to the middle position of the inner bottom end of the filter tank, a filtering mechanism is connected to the inner and outer ends of the filter tank, the filtering mechanism comprises a filtering unit and a heating unit, the filtering unit is arranged inside the filter tank, and the heating unit is arranged at the outer end of the filter tank.

[0009] The filter unit includes a motor, a filter, a connecting rod, an upper scraper, a lower scraper, a threaded rod, a fixing ring and a rotating rod. The motor is fixedly connected to the middle position of the upper side of the tank cover, the rotating rod is fixedly connected to the lower end of the output shaft of the motor, the filter is fixedly connected to the lower end of the outer side of the rotating rod, the connecting rod is fixedly connected to the upper and lower ends of the outer side of the rotating rod, the upper scraper is fixedly connected to the end of the connecting rod at the upper end of the outer side of the rotating rod away from the rotating rod, the lower scraper is fixedly connected to the end of the connecting rod at the lower end of the outer side of the rotating rod away from the rotating rod, the threaded rod is fixedly connected to the left and right ends of the upper side of the filter tank, and the fixing ring is connected to the outer side of the threaded rod.

[0010] A further improvement is that the ends of the upper and lower scrapers away from the connecting rod are slidably connected to the inner side of the filter tank. Thus, by starting the motor, the output shaft of the motor rotates to drive the rotating rod at the lower end to rotate, and at the same time, the upper and lower scrapers at the outer ends are driven to slide along the inner side of the filter tank, so that the water-based paint attached to the inner wall of the filter tank can be scraped off by the upper and lower scrapers, thereby accelerating the filtering efficiency of the water-based paint.

[0011] A further improvement is that the outer edge of the filter screen is slidably connected to the inner side of the filter tank, so that the water-based paint entering the filter tank will be completely filtered by the filter screen in the filter tank.

[0012] A further improvement is that a limiting hole is provided at the middle position of the left and right ends of the tank cover, and the outer side of the threaded rod is slidably connected to the inner side of the limiting hole. Therefore, when the tank cover is placed on the filter tank, the limiting holes at the left and right ends of the tank cover will slide to the outer side of the threaded rod, thereby limiting the movement of the tank cover when it is disassembled.

[0013] A further improvement is that the inner side of the fixing ring is provided with an internal thread, the outer side of the threaded rod is threadedly connected to the inner side of the fixing ring, and the lower side of the fixing ring abuts against the left and right ends of the upper side of the tank cover. Thus, after the tank cover is placed on the filter tank and the limiting hole passes through the threaded rod, the fixing ring is threadedly connected to the outer side of the threaded rod until the lower side of the fixing ring contacts the left and right ends of the upper side of the tank cover, so that the tank cover can be fixed to the upper end of the filter tank.

[0014] A further improvement is that the heating unit includes an outer frame, a water inlet pipe and a water outlet pipe, the outer frame is fixedly connected to the outside of the filter tank, the water inlet pipe is fixedly connected to the lower left end of the inner part of the outer frame, and the water outlet pipe is fixedly connected to the upper right end of the inner part of the outer frame.

[0015] A further improvement is that the upper scraper and the lower scraper are in an arc shape, so that when the upper scraper and the lower scraper are located inside the filter tank and rotate to scrape off the water-based paint, the arc-shaped upper scraper and the lower scraper can make the water-based paint slide down more quickly, thereby improving the filtering efficiency of the water-based paint.

[0016] In summary, the present application discloses a water-based paint filtering device that is easy to disassemble, assemble and clean.

[0017] According to the technical solution, after the fixing ring is removed from the outer side of the threaded rod by rotating it, the tank cover can be removed from the upper end of the filter tank, and the rotating rod and the filter screen can be taken out of the filter tank together, so that the filter screen can be taken out for inspection when it is damaged.

[0018] Furthermore, by injecting hot water into the outer frame from the water inlet pipe and then discharging it from the water outlet pipe, the hot water in the outer frame will heat the water-based glue in the filter tank, so that the water-based paint inside the filter tank will not solidify during filtration.
