Description

Technical Field

[0001] The utility model relates to the technical field of water-based functional coating filtration, in particular to a filtering device for water-based functional coating. Background Art

[0002] With the rapid development of the national economy and the continuous improvement of social levels, the development of my country's construction and decoration industry is getting better and better. In order to reflect the beauty of the house, residents now usually paint the walls with different colors of paint. Nowadays, there is a new type of paint in the paint market that is gradually attracting everyone's attention, that is, water-based paint. When processing water-based paint, in order to remove impurities in the paint, a special filter device for water-based paint is used.

[0003] However, when the existing water-based paint filtering device on the market is in use, after the water-based paint is filtered, some water-based paint will remain on the inner wall of the filter box, which is inconvenient to flush the inside of the filter box and may affect the next use of the device.

[0004] For example, a filtering device for water-based paint disclosed in Chinese patent CN213192692U is provided with a flushing mechanism. After the filtering of the water-based paint is completed, a proper amount of water is injected into the water storage tank. The water pump is started through the control panel. The water pump will transport the water in the water storage tank to the inside of the water storage cavity through the water pipe. Due to the effect of water pressure, the water in the water storage cavity will be sprayed out through the nozzle. The sprayed water can clean the inner wall of the filter box, which is convenient for flushing the inside of the filter box, thereby improving the functionality of the device.

[0005] However, during the filtering work, part of the water-based functional coating will adhere to the inner wall of the filter box, and direct flushing after the filtering work is completed will cause waste.

[0006] For this reason, we urgently need to provide a filtering device for water-based functional coatings with a scraping function. Utility Model Content

[0007] The purpose of the utility model is to provide a filtering device for water-based functional coatings, so as to solve the problem in the above-mentioned background technology that during filtering, part of the water-based functional coatings will adhere to the inner wall of the filter box, and direct flushing after the filtering work is completed will cause waste.

The feed pipe is fixedly connected to the middle position of the inner left end of the tank cover, the filter screen is fixedly connected to the inner bottom end of the filter tank, the motor is fixedly connected to the upper middle position of the tank cover, the threaded rod is fixedly connected to the lower end of the output shaft of the motor, the baffle is fixedly connected to the lower end of the threaded rod, the movable plate is connected to the outer end of the threaded rod, the scraper ring is fixedly connected to the outer end of the movable plate, and the slider is fixedly connected to the left and right ends of the outer side of the scraper ring.

[0010] A further improvement is that vertical slide grooves are provided at the left and right ends of the inner side of the filter tank, the outer side of the slider is slidably connected to the inner side of the slide groove, and the outer side of the scraper ring is slidably connected to the inner side of the filter tank. Therefore, when the scraper ring moves, the slider at its outer end will slide along the inner side of the slide groove, thereby limiting the movement of the scraper ring.

[0011] A further improvement is that a threaded hole is provided in the middle of the movable plate, and the outer side of the threaded rod is threadedly connected to the inner side of the threaded hole, so that when the output shaft of the motor is started and the threaded rod is driven to rotate, the outer movable plate and the scraper ring can be driven to slide along the inner side of the filter tank.

[0012] A further improvement is that the upper side of the baffle plate abuts against the lower side of the movable plate, so that when the threaded rod is rotated to drive the movable plate and the scraper ring to move down to the lower end of the threaded rod, they will be blocked by the baffle plate and will not fall from the lower end of the threaded rod.

[0013] A further improvement is that the cleaning unit includes a water tank, a water pump, a connecting pipe, a connecting rod, an annular tube and a nozzle, the water tank is fixedly connected to the upper right end of the base, the water pump is fixedly connected to the left end of the water tank, the connecting pipe is fixedly connected to the left end of the water pump, the connecting rod is fixedly connected to the middle position of the lower left end of the tank cover, the annular tube is fixedly connected to the lower end of the connecting rod, and the nozzle is fixedly connected to the lower end of the annular tube in an equal arc.

[0014] A further improvement is that the end of the connecting pipe away from the water pump is fixedly connected to the upper right end of the inner part of the annular pipe. Therefore, after the filtering work is completed, the cleaning water in the water storage tank is pumped into the connecting pipe by starting the water pump, and then flows into the annular pipe from the other end of the connecting pipe, and then sprayed into the filter tank through the nozzle to wash the residual water-based paint in the filter tank.

[0015] A further improvement is that a through groove is provided at the front end of the filter tank, and an observation window is fixedly connected to the inner side of the through groove, and the observation window is made of transparent glass, so that the filtering situation in the filter tank can be observed at any time through the observation window.

[0016] In summary, the present application discloses a filtering device for water-based functional coatings.

[0017] This technical solution starts the motor and rotates its output shaft to drive the threaded rod to rotate, which can drive the outer movable plate and scraper ring to slide along the inner side of the filter tank, scraping the water-based functional paint attached to the inner wall of the filter tank onto the filter screen for filtering and then discharging it from the lower end, thereby avoiding the waste of water-based functional paint.

[0018] Furthermore, after the filtering work is completed, the cleaning water in the water tank is pumped into the connecting pipe by starting the water pump, and then flows into the annular pipe from the other end of the connecting pipe, and then sprayed into the filter tank through the nozzle to rinse the residual water-based paint in the filter tank.
