Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically a waterproof coating filtration device with a quick-replaceable filter screen. Background Technology

[0002] Waterproof coatings are single-component water-emulsion type waterproof coatings made from pure acrylic polymer emulsion as the base material and with the addition of other additives. After curing, the waterproof film formed by the waterproof coating has certain extensibility, elasticity, crack resistance, impermeability, and weather resistance, and can play a role in waterproofing, seepage prevention, and protection. In addition, waterproof coatings have good temperature adaptability, are easy to operate, and are easy to repair and maintain. During the processing of waterproof coatings, they are filtered to improve the purity of the coating and avoid the presence of particles in the coating that would affect its use.

[0003] However, in existing waterproof coating filtration equipment, the filter screen is usually located inside the filter box. Therefore, replacing the filter box requires opening the box lid and removing the filter screen, which is cumbersome and inconvenient for personnel. Therefore, this invention proposes a waterproof coating filtration device with a quickly replaceable filter screen. Utility Model Content

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0037] This utility model provides a waterproof coating filtration device with a quickly replaceable filter screen. Please refer to [link / reference]. Figures 1-4 The filter box 10 includes a filter box 10, the bottom of which is detachably connected to a circular plate 20 via a connecting assembly. A filter screen 21 is fixedly installed in the middle of the circular plate 20. A sealing ring is provided between the circular plate 20 and the filter box 10. Several brackets 11 are fixedly installed on the outside of the filter box 10. A box cover 12 is threadedly connected to the top of the filter box 10. A feed pipe is provided on the top side wall of the filter box 10.

[0038] The connecting components include: square hole 30, support plate 31, rotating rod 32, and square rod 33;

[0039] The outer side of the circular plate 20 has several square holes 30. A support plate 31 is fixedly installed on the outer side of the filter box 10 above the square holes 30. The bottom of the support plate 31 is rotatably connected to the rotating rod 32 through the bearing. The rotating rod 32 passes through the square holes 30. A square rod 33 is fixedly installed on the bottom of the rotating rod 32 and is in contact with the circular plate 20. The square rod 33 is arranged in a cross shape with the square holes 30 after rotation. The diameter of the rotating rod 32 is the same as the width of the square holes 30 and the square rod 33.

[0040] It also includes a mixing assembly for mixing the waterproof coating, and the mixing assembly is located on the cover 12.

[0041] The stirring assembly includes: a rotating shaft 13, a stirring rod 14, a servo motor 15, a crossbar 16, and brush bristles 17;

[0042] The rotating shaft 13 is rotatably connected to the box cover 12 via bearings. Several stirring rods 14 are fixedly installed on the rotating shaft 13. The servo motor 15 is fixedly installed on the top of the box cover 12, and the output shaft of the servo motor 15 is fixedly connected to the rotating shaft 13. The crossbar 16 is fixedly installed on the bottom of the rotating shaft 13. Several brush filaments 17 are provided at the bottom of the crossbar 16, and the brush filaments 17 are in contact with the filter screen 21.

[0043] It also includes a limiting component for limiting the position of the rotating rod 32, and the limiting component is located on the bottom of the support plate 31.

[0044] The limiting assembly includes: a hollow tube 40, a limiting plate 41, a positioning plate 42, and a rubber strip 43;

[0045] A hollow tube 40 is fixedly installed on the bottom of a support plate 31, and a rotating rod 32 passes through the hollow tube 40. Several sets of limiting plates 41 are fixedly installed at equal intervals inside the hollow tube 40. Positioning plates 42 are fixedly installed at both ends of the rotating rod 32. A rubber strip 43 is fixedly installed on one end of the positioning plate 42, and the rubber strip 43 rotates to be positioned between the two sets of limiting plates 41. When the rubber strip 43 enters or exits between the two sets of limiting plates 41, it generates a resistance force that can be felt by a person, thus limiting the rotation angle of the rotating rod 32. Figure 4 As shown, two sets of limiting plates 41 are provided at each of the four positions of the hollow tube 40. When the rubber strip 43 is located in the two sets of limiting plates 41 on the left and right, its square rod 33 and square hole 30 are arranged in a cross shape. Conversely, when the rubber strip 43 is located in the two sets of limiting plates 41 at the front and rear, its square rod 33 and square hole 30 are aligned.

[0046] In practical use, the operating steps for those skilled in the art are as follows:

[0047] First, place a container directly below the filter box 10. Then, place the waterproof coating into the filter box 10 through the feed pipe. At this time, the waterproof coating will be filtered through the filter screen 21, and the qualified waterproof coating will fall into the container. During this process, the servo motor 15 will rotate the rotating shaft 13. When the rotating shaft 13 rotates, the stirring rod 14 will stir the waterproof coating to prevent the particles in the waterproof coating from remaining on the filter screen 21. At the same time, the rotating crossbar 16 will use the brush 17 to sweep away the particles remaining on the filter screen 21 to prevent the particles from clogging the filter screen 21.

[0048] When installing the filter screen 21, first align the square hole 30 and the square rod 33, then pass the square rod 33 through the square hole 30 until the circular plate 20 and the filter box 10 come into contact. At this time, the square rod 33 will be rotated until the square rod 33 and the square hole 30 are arranged in a cross shape, so that the filter screen 21 can be installed.

[0049] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
