Description

Technical Field

[0001] The utility model relates to the technical field of acrylic emulsion filtration, in particular to an acrylic emulsion filtration device with a self-cleaning function. Background Art

[0002] Acrylic emulsion is a milky white or nearly transparent viscous liquid. Acrylic emulsion is an emulsion made by copolymerization of pure acrylic ester monomers. It is a small-particle, multi-purpose, high-performance emulsion suitable for a variety of paint formulations. It has outstanding water resistance and weather resistance, especially in high-gloss and semi-gloss paints. Acrylic emulsion often contains powdery particles, which need to be filtered out using a filter device.

[0003] The existing acrylic emulsion filtering device generally passes through the filter bag under the action of high-pressure gas, and the powder particles adhere to the filter bag, and the acrylic emulsion flows out from the discharge port. This method has the disadvantage of being inconvenient to clean. When there are many powder particles in the acrylic emulsion, the powder particles quickly block the filter bag, making the liquid unable to flow, and the permeability is poor, which affects the filtration efficiency of the acrylic emulsion filtration. To address this problem, an acrylic emulsion filtering device with a self-cleaning function is now provided. Summary of the invention

DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] The utility model provides the following preferred embodiments:

[0025] Embodiment 1, as Figure 1-Figure 4 As shown, an acrylic emulsion filtering device with a self-cleaning function includes a filtering tank 11, a tank cover 25 is installed on the top of the filtering tank 11, and also includes a filtering mechanism and a cleaning mechanism;

[0026] The filter mechanism includes a filter bag 13 and a mounting assembly. The filter bag 13 is located inside the filter tank 11. The mounting assembly is located between the filter tank 11 and the filter bag 13. The mounting assembly is used to install the filter bag 13, which is convenient for disassembly of the filter bag 13, and further for replacement and maintenance of the filter bag 13.

[0027] The cleaning mechanism includes an L-shaped scraper 14, a guide assembly and a rotating assembly. The L-shaped scraper 14 is located on one side of the filter bag 13, the inner side of the L-shaped scraper 14 is in contact with the outer wall of the filter bag 13, and the rotating assembly is located between the L-shaped scraper 14 and the filter tank 11;

[0028] The rotating component can drive the L-shaped scraper 14 to rotate, so that the L-shaped scraper 14 can rotate on the surface of the filter bag 13. When the L-shaped scraper 14 rotates, the powder particles attached to the surface of the filter bag 13 can be scraped off to avoid the powder particles clogging the filter bag 13 and reducing the permeability of the filter bag 13, thereby helping to improve the filtration efficiency of the filter bag 13. The guide component is used to play a guiding role when the L-shaped scraper 14 rotates, thereby increasing the stability of the L-shaped scraper 14.

[0029] like Figure 1-Figure 4As shown, the rotating assembly includes a ring gear 15, a gear 16 and a motor 17, the ring gear 15 is rotatably arranged inside the filter tank 11, the L-shaped scraper 14 is fixed inside the ring gear 15, the gear 16 is rotatably arranged on the filter tank 11, the gear 16 and the ring gear 15 are meshed, the motor 17 is fixedly installed at the bottom end of the filter tank 11, and the output end of the motor 17 is fixedly connected to the bottom end of the gear 16;

[0030] When the surface of the filter bag 13 needs to be cleaned, the motor 17 is controlled to work, and the motor 17 can drive the gear 16 to rotate. Since the gear 16 and the ring gear 15 are meshingly connected, when the gear 16 rotates, it can drive the ring gear 15 to rotate, so that the L-shaped scraper 14 can rotate on the outside of the filter bag 13. When rotating, the L-shaped scraper 14 can scrape off the powder particles on the outer surface of the filter bag 13, thereby achieving a cleaning effect on the filter bag 13, avoiding the powder particles from clogging the filter bag 13, and reducing the passability of the filter bag 13.

[0031] like Figure 1-Figure 4 As shown, the guide assembly includes two annular guide rails 18, two rotating rings 19 and two connecting rods 20. The two annular guide rails 18 are arranged up and down and are fixed to the inner wall of the filter tank 11. Each rotating ring 19 is rotatably arranged inside an annular guide rail 18. One end of each rotating ring 19 is fixedly connected to one end of a connecting rod 20, and the other end of each connecting rod 20 is fixedly connected to the L-shaped scraper 14.

[0032] When the L-shaped scraper 14 rotates, the connecting rod 20 can drive the rotating ring 19 to rotate inside the annular guide rail 18, thereby guiding the rotation of the L-shaped scraper 14 and facilitating stability.

[0033] like Figure 1-Figure 4 As shown, the mounting assembly includes a mounting platform 12 and bolts 26. The mounting platform 12 is fixedly mounted on the inner wall of the filter tank 11. The top of the filter bag 13 is overlapped above the mounting platform 12. The mounting platform 12 and the filter bag 13 are connected by a plurality of bolts 26.

[0034] The filter bag 13 can be mounted on the mounting platform 12 by using a plurality of bolts 26, thereby enabling the installation of the filter bag 13, making installation and removal more convenient.

[0035] like Figure 1-Figure 4 As shown, a feed pipe 21 is installed on one side of the filter tank 11, a discharge pipe 22 is installed on the side of the filter tank 11 away from the feed pipe 21, one end of the discharge pipe 22 extends into the interior of the filter bag 13, and a vent pipe 24 is installed on one side above the tank cover 25;

[0036] It should be noted that a pump body is provided at one end of the discharge pipe 22 away from the filter bag 13, and the acrylic emulsion containing powdered particles can enter the interior of the filter tank 11 through the feed pipe 21. Under the action of the filter bag 13, the acrylic emulsion can enter the interior of the filter bag 13 and be output through the discharge pipe 22 under the action of the pump body, while the powdered particles are blocked outside the filter bag 13, thereby achieving a filtering effect on the acrylic emulsion.

[0037] like Figure 1-Figure 4 As shown, the bottom end of the filter tank 11 is conical, and a discharge pipe 23 is installed at the bottom end of the filter tank 11. It should be noted that a valve is provided on the discharge pipe 23. The setting of the discharge pipe 23 facilitates the discharge of powder particles and the cleaning of powder particles.
