Description

Technical Field

[0001] This utility model relates to the technical field of anti-corrosion and beautification composite coating materials, specifically to a mixing device for anti-corrosion and beautification composite coating materials for cement concrete. Background Technology

[0002] Anti-corrosion and aesthetic composite coatings are coatings that combine corrosion protection and aesthetic appeal, typically used to protect and decorate cement concrete structures. The design goal of these materials is to extend the lifespan of buildings while enhancing their visual appeal. A common type of anti-corrosion and aesthetic composite coating is epoxy anti-corrosion coating, which is mostly used on cement concrete floors.

[0003] According to patent publication number CN211274360U, published on August 18, 2020, a premixing device for producing epoxy anti-corrosion coatings is disclosed, including a preparation box, a mixing box, and a drive motor. A separation plate is welded and fixed to the middle of the preparation box, and the outer ends of a first bearing plate are rotatably mounted on the left and right inner walls of the preparation box. Second bearing plates are mounted on both the front and rear sides of the first bearing plate, and the lower ends of a measuring plate are attached to the upper front and rear ends of the first bearing plate and the upper inner ends of the second bearing plate. A device fixed to the inner wall of the preparation box is provided below both the first and second bearing plates. An electric telescopic rod is mounted on the mixing box, and a connecting rod is rotatably connected to the upper end of the electric telescopic rod. The mixing box is located below the preparation box, and a baffle is welded to the middle of the lower end of the preparation box. The drive motor is located at the lower end of the preparation box, and a mixing shaft is installed at the output end of the drive motor. A first mixing rod is welded to the lower end of the mixing shaft, and second mixing rods are evenly distributed above the first mixing rods and welded to the mixing shaft. The lower surface of the first mixing rods is in contact with the bottom of the mixing box. A control board is snapped onto the bottom right end of the mixing box, and a pouring plate fixed to the bottom of the mixing box is provided below the control board.

[0004] In the existing technology, including the aforementioned patents, the production process of epoxy anti-corrosion coatings currently requires the formulation of multiple raw materials, which are then mixed and stirred to form a corresponding mixture to facilitate further production. Currently, commercially available epoxy resin anti-corrosion coatings are produced by directly adding large blocks of epoxy resin material into a mixing drum. The mixture, along with the heating of the internal solution and the mixing drum, melts the epoxy resin material. However, in actual operation, large blocks of epoxy resin melt slowly, affecting the overall mixing and production efficiency. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-6 As shown, a mixing device for a cement concrete anti-corrosion and beautification composite coating material includes a mixing drum 1 and a mixing rod 41 rotatably disposed therein, as well as a plurality of crushing rods 43 fixedly installed on the mixing rod 41 and a grinding table 5 fixedly installed at the bottom of the crushing rods 43. A material dropping table 6 is fixedly installed inside the mixing drum 1. The crushing rods 43 are movably disposed in the through grooves 61 opened on the material dropping table 6, and a gradually narrowing channel 63 is provided between the inclined bottom 62 provided at the bottom of the material dropping table 6 and the top of the grinding table 5. Large pieces of epoxy resin material are placed into the mixing drum 1, and then slide down the discharge platform 6 into the through groove 61. At this time, the stirring rod 41 rotates to drive the crushing rod 43 to rotate in the through groove 61, thereby initially crushing the large pieces of epoxy resin material in the through groove 61. The material that is partially crushed into smaller pieces slides into the gradually narrowing channel 63. At this time, the small pieces of material are squeezed by the grinding table 5 and the inclined bottom 62 to perform a certain degree of grinding and crushing. Then the ground material slides into the mixing drum 1 for mixing and stirring, thereby improving the mixing efficiency of the material.

[0028] Specifically, a main motor 4 is fixedly installed on the top of the mixing drum 1, and the top end of the stirring rod 41 is fixedly installed at the output end of the main motor 4. A feed inlet 11 is opened on the top of the mixing drum 1.

[0029] As a further technical solution provided by this utility model, the top surface of the grinding table 5 is provided with first grinding protrusions 52 arranged in a circular array.

[0030] Specifically, the first grinding protrusion 52 can enhance the grinding efficiency of the grinding table 5 on the material.

[0031] Furthermore, a narrow-diameter side plate 53 is fixedly installed on the side of the grinding table 5, and the outer wall of the narrow-diameter side plate 53 is provided with a second grinding protrusion 54 arranged in a circular array.

[0032] Specifically, the material can be further ground using the narrow-diameter side plate 53 on the grinding table 5 and the second grinding protrusion 54 on the narrow-diameter side plate 53.

[0033] Furthermore, a wide-diameter side plate 55 is fixedly installed at the bottom of the narrow-diameter side plate 53, and the outer wall of the wide-diameter side plate 55 is provided with a third grinding protrusion 56 arranged in a circular array.

[0034] Specifically, the material ground by the second grinding protrusion 54 can be ground again by the third grinding protrusion 56 to improve the grinding effect.

[0035] Furthermore, an annular plate 7 is fixedly installed on the inner wall of the mixing drum 1, and an upper grinding protrusion 71 and a lower grinding protrusion 72 arranged in a circular array are fixedly installed on the inner wall of the annular plate 7.

[0036] Specifically, such as Figure 4 As shown, when the material being ground in the gradually narrow channel 63 slides down between the second grinding protrusion 54 and the upper grinding protrusion 71, the material is ground to a certain extent by the second grinding protrusion 54 and the upper grinding protrusion 71, and then the material ground into small pieces falls between the third grinding protrusion 56 and the lower grinding protrusion 72, and is further ground and crushed by the third grinding protrusion 56 and the lower grinding protrusion 72.

[0037] Furthermore, an inner ring groove 51 is provided on the grinding table 5, and the sleeve 3 fixedly installed at the bottom of the stirring cylinder 1 extends into the inner ring groove 51. The sealing block 42 fixedly installed on the stirring rod 41 is movably set at the top of the sleeve 3, and a return port 34 is provided on the outer wall of the sleeve 3 at the top.

[0038] Specifically, the top of the sleeve 3 is sealed by the sealing block 42, and then the mixture inside the sleeve 3 flows along the return port 34 to the top of the grinding table 5, thereby accelerating the sliding of the material on the top of the grinding table 5 and carrying away some of the material attached to the top of the grinding table 5 and the bottom of the inclined surface 62. Furthermore, the contact between the mixture and the material can melt the material to a certain extent in advance.

[0039] Furthermore, the spiral plate 44, which is fixedly installed on the outer wall of the stirring rod 41, is movably disposed inside the sleeve 3, and the outer wall of the sleeve 3 at the bottom end is provided with a liquid inlet 32.

[0040] Specifically, the rotation of the stirring rod 41 drives the spiral plate 44 to rotate inside the sleeve 3, so that the mixture in the stirring drum 1 enters the sleeve 3 along the liquid inlet 32. As the spiral plate 44 rotates, it drives the mixture to move upward, and then flows out along the return port 34 to the top of the grinding table 5.

[0041] Furthermore, a hollow cavity 31 is provided inside the sleeve 3, and a heating wire 33 is spirally wound inside the hollow cavity 31.

[0042] Specifically, the heating wire 33 heats the sleeve 3, thereby heating the mixture in the mixing drum 1 and the mixture in the sleeve 3. When the heated mixture flows to the top of the grinding table 5, the melting speed of the material can be increased.

[0043] Furthermore, a first stirring rack 57 is fixedly installed on the bottom of the wide-diameter side plate 55, and a second stirring rack 58 is fixedly installed on the first stirring rack 57.

[0044] Specifically, the first stirring rack 57 and the second stirring rack 58 can be used to mix and stir the ground and pulverized materials, thereby improving the mixing effect of the materials.

[0045] Furthermore, the bottom of the mixing drum 1 is fixedly connected to the liquid outlet pipe 2, a piston block 23 is slidably installed inside the liquid outlet pipe 2, a drain port 22 is opened on the outer wall of the liquid outlet pipe 2, and an electric push rod 21 is fixedly installed inside the liquid outlet pipe 2.

[0046] Specifically, piston block 23 is fixedly installed at the output end of electric push rod 21. The electric push rod 21 drives piston block 23 to move down, so that the mixed liquid in the mixing drum 1 flows along the liquid outlet pipe 2 and is finally discharged from the mixing drum 1 along the liquid outlet 22.

[0047] Working principle: The main motor 4 drives the stirring rod 41 to rotate, and then the stirring rod 41 drives the grinding table 5 to rotate. At this time, large pieces of epoxy resin material slide down the feeding table 6 into the through groove 61. The rotation of the stirring rod 41 drives the crushing rod 43 to rotate in the through groove 61, thereby initially crushing the large pieces of epoxy resin material in the through groove 61. Some of the crushed material slides into the gradually narrowing channel 63. At this time, the small pieces of material are squeezed by the grinding table 5 and the inclined bottom 62 to perform a certain degree of grinding and crushing. Then the ground material slides between the second grinding protrusion 54 and the upper grinding protrusion 71. The material is ground to a certain extent by the second grinding protrusion 54 and the upper grinding protrusion 71. Then the ground material falls between the third grinding protrusion 56 and the lower grinding protrusion 72, and is further ground and crushed by the third grinding protrusion 56 and the lower grinding protrusion 72. The rotation of the stirring rod 41 drives the spiral plate 44 to rotate within the sleeve 3, causing the mixture in the stirring drum 1 to enter the sleeve 3 through the inlet 32. As the spiral plate 44 rotates, it causes the mixture to move upwards and then flow out through the return port 34 to the top of the grinding table 5, thereby accelerating the sliding of material on the top of the grinding table 5 and carrying away some of the material adhering to the top of the grinding table 5 and the bottom of the inclined surface 62. Furthermore, the contact between the mixture and the material allows for some pre-melting of the material, thus improving the mixing efficiency.

[0048] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
