Technical Field

[0001] The utility model belongs to the technical field of paint filtering, and in particular relates to a water-type filtering structure of a spraying device. Background Art

[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually a viscous liquid based on resin, oil, or emulsion, with or without pigments and fillers, and with corresponding additives, prepared with organic solvents or water. Paints can be divided into solvent-based paints and water-based paints (emulsion paints and water-based paints) according to the dispersion medium used.

[0003] In the prior art, a Chinese patent with a reference publication number of CN 213222914 U discloses a coating mixing device for a spraying device with a filtering structure, comprising a base, a connecting sleeve fixedly connected to the side of the top of the base, an adjusting rod connected to an internal movable sleeve of the connecting sleeve, and a front side of the connecting sleeve fixedly connected to the front side of the adjusting rod by a bolt, a screw hole is provided on the front side of the adjusting rod, and a mixing box is fixedly connected to the top of the adjusting rod. The utility model provides a filter net, which can facilitate filtering of the added water-based coating during the mixing process of the water-based coating, and can effectively remove condensate and other debris in the water-based coating.

[0004] The comparative document provides a spraying equipment that can perform filtering, but the above patent only filters water-based paint. Since the spraying material is composed of refractory aggregate, powder, and binder (or with admixture), the refractory aggregate, powder, and binder need to be stirred and mixed. After mixing, there are some large suspended particles, which are easy to clog the feed point and affect the subsequent spraying.

[0005] Therefore, a water filtering structure of a spraying equipment is proposed. Utility Model Content

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model embodiment provides a water type filtering structure of a spraying device, such as Figure 1-4 As shown, it includes a spray mixing barrel 1, a filter cover 2 is fixedly connected to the central position of the inner bottom of the spray mixing barrel 1 by bolts, a discharge pipe 3 is welded to the central position of the bottom of the filter cover 2, and the bottom end of the discharge pipe 3 is fixedly connected to the paint storage box 4 by bolts. The paint storage box 4 is a hollow rectangular structure, and a discharge pipe 5 is fixedly connected to the outer wall of one side of the paint storage box 4 by bolts. The discharge pipe 5 is an L-shaped pipe, and the discharge pipe 5 and the paint storage box 4 are connected. One end of the discharge pipe 5 is located at the upper position of the outer wall of one side of the paint storage box 4, and a high-pressure pump 61 in the anti-blocking component 6 is fixedly connected to the outer wall of one side of the paint storage box 4 adjacent to the discharge pipe 5 by bolts. A first connecting pipe 62 is fixedly connected between the output end of the high-pressure pump 61 and the discharge pipe 3 by bolts, and a second connecting pipe is fixedly connected between the input end of the high-pressure pump 61 and the paint storage box 4 by bolts. 63, the first connecting pipe 62 and the second connecting pipe 63 are both L-shaped pipes, and the first connecting pipe 62 is connected to the discharge pipe 3, and the second connecting pipe 63 is connected to the paint temporary storage box 4. A first solenoid valve 64 is fixedly connected to the outer wall of one side of the discharge pipe 3 by bolts, and a second solenoid valve 65 is fixedly connected to the outer wall of one side of the discharge pipe 5 by bolts. The high-pressure pump 61, the first solenoid valve 64 and the second solenoid valve 65 are all electrically connected to the timer 66. A timer 66 is embedded in the outer wall of one side of the paint temporary storage box 4 near the discharge pipe 5. A motor 7 is fixedly connected to the central position of the top of the spray mixing barrel 1 by bolts, and a stirring paddle 8 is fixedly connected to the output end of the motor 7. A feed hopper 9 is fixedly connected to the top of the spray mixing barrel 1 near the motor 7 by bolts, and three support legs 10 are fixedly connected to the bottom of the spray mixing barrel 1 by bolts at equal intervals.

[0024] It should be noted that, since the existing spraying equipment only filters water-based paint, and since the spray paint is composed of refractory aggregate, powder, and binder (or with additives), the refractory aggregate, powder, and binder need to be stirred and mixed. After mixing, there are some large suspended particles, which are easy to block the feed point, thereby affecting the subsequent spraying. This embodiment can achieve a reverse impact on the filter holes on the filter cover 2 by regularly pressing the filtered high-pressure and high-flow rate spray paint into the interior of the filter cover 2, thereby flushing away the suspended particles blocked in the filter holes, ensuring smooth subsequent filtration of the filter cover 2, avoiding the problem of gradual decrease in filtration efficiency caused by gradual clogging of the filter cover 2, and maintaining the filtration efficiency of the spray paint. Through the setting of the paint temporary storage box 4, a temporary storage space can be provided for the filtered spray paint, thereby facilitating subsequent flushing use.

[0025] Specifically, in the present embodiment, the present scheme mainly comprises an anti-clogging component 6. When in use, the spray paint is poured into the spray mixing barrel 1 through the feed hopper 9. The motor 7 drives the stirring paddle 8 to rotate at a high speed through its output end. The stirring paddle 8 stirs and mixes the spray paint in the spray mixing barrel 1. The fully mixed spray paint passes through the filter holes on the filter cover 2 and enters the interior of the filter cover 2. It enters the interior of the paint temporary storage box 4 through the diversion of the discharge pipe 3. The paint temporary storage box 4 stores the filtered spray paint. When the spray paint in the paint temporary storage box 4 is filled with the spray paint, the spray paint in the paint temporary storage box 4 is discharged through the discharge pipe 5. The time of the timer 66 is set. When the set time is reached, the first solenoid valve 64 and the second solenoid valve 64 are closed. Valve 65 is started, the first solenoid valve 64 and the second solenoid valve 65 are closed, the feed pipe 3 and the discharge pipe 5 are blocked, at this time, the high-pressure pump 61 works, and after the high-pressure pump 61 works, the spray paint in the paint temporary storage box 4 is quickly drawn into the feed pipe 3 through the second connecting pipe 63 and the first connecting pipe 62. Since the lower end of the feed pipe 3 is blocked, the high-pressure and high-flow rate spray paint flows to the filter cover 2, and the spray paint is sprayed out from the filter holes on the filter cover 2. The suspended particles of the spray paint blocked in the filter holes are washed away, thereby ensuring the smooth subsequent filtration of the filter cover 2 and realizing the regular automatic cleaning of the filter cover 2. After completing one cleaning, the high-pressure pump 61 stops working, the first solenoid valve 64 and the second solenoid valve 65 are opened, and the discharge of the spray paint after filtration is restored.

[0026] In a further preferred embodiment of the present invention, Figure 1 and Figure 4 As shown, the filter cover 2 is a hollow cylindrical structure, and a filter hole is opened on the outer wall of one side of the filter cover 2, and the filter cover 2 is connected to the feed pipe 3.

[0027] In this embodiment, the filter cover 2 can have filtering ability, so as to filter the suspended particles in the spray material, avoid the large particles of the spray material clogging the subsequent spray nozzle, and avoid the problem of many protrusions after spraying.
