Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof coating production technology, specifically a waterproof powder mixing device for waterproof coating production. Background Technology
[0002] During the mixing process of waterproof powder used in the production of waterproof coatings, the particles of waterproof powder are usually small, have a large specific surface area, and high surface energy. They easily adsorb the surrounding air to form an air film. This air film acts like an elastic cushion. When the particles approach each other, the air film is compressed, generating a repulsive force that prevents the particles from getting closer and merging. This reduces the chance of direct contact between the waterproof powder particles and other raw materials, making it difficult for them to interpenetrate and merge. Furthermore, the surface properties of the air film are different from those of the waterproof powder particles themselves, affecting the wetting effect of other raw materials on the waterproof powder. As a result, the waterproof powder is difficult to disperse evenly among other raw materials during mixing.
[0003] Therefore, there is an urgent need for a waterproof powder mixing device for the production of waterproof coatings to solve the above problems. Utility Model Content

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1
[0021] Please see Figures 1-5 The figure shows a waterproof powder mixing device for producing waterproof coatings, including a mixing tank 101 and an inlet pipe 102 and an outlet pipe 103 respectively disposed at the top and bottom of the mixing tank 101, and also includes a mixing component disposed in the mixing tank 101 for mixing the waterproof powder.
[0022] The mixing assembly includes a rotating rod 201 rotatably connected to the mixing tank 101. The side wall of the rotating rod 201 is provided with multiple sets of stirring components. Each set of stirring components includes multiple stirring plates 202 fixedly connected to the side wall of the rotating rod 201. The stirring plates 202 are arranged in a ring array. A rotating ring 203 is rotatably connected to the inner wall of the mixing tank 101. Multiple mixing plates 204 are fixedly connected to the inner wall of each rotating ring 203 near the rotating rod 201. The mixing tank 101 is provided with a rotating assembly for driving the stirring plates 202 and mixing plates 204 to rotate in opposite directions.
[0023] It should be noted here that: by setting up the mixing component, under the combined action of the rotating component and the supporting component, the air film formed by the waterproof powder with the air during the mixing process due to its large specific surface area and high surface energy is sheared and broken, thereby increasing the opportunity for direct contact between the waterproof powder particles and other raw materials, facilitating their interpenetration and fusion, and thus improving the uniformity of the dispersion of the waterproof powder in other raw materials during mixing.
[0024] Please see Figures 2-5In the figure, each stirring plate 202 and mixing plate 204 has a serrated plate 205 fixedly connected to its two opposite side walls, and each serrated plate 205 has an inclined surface 206 on its two opposite side walls.
[0025] It should be noted that, with the serrated plate 205 in place and guided by the inclined plane 206, when two adjacent serrated plates 205 rotate in opposite directions, the serrations will cut the agglomerates. This cutting action can effectively destroy the interaction forces between particles in the agglomerates.
[0026] Please see Figures 2-5 In the figure, each stirring plate 202 and mixing plate 204 has multiple conical rods 207 fixedly connected to its two opposite side walls;
[0027] It should be noted here that the various tapered rods 207 can be used to puncture the air film generated on the surface of the waterproof powder.
[0028] Please see Figure 3 The rotating assembly shown in the figure includes an L-shaped plate 301 fixedly connected to the top of the mixing tank 101. A rotating rod 201, with one end away from the discharge pipe 103, passes through the mixing tank 101 and is connected to the L-shaped plate 301. A connecting rod 302 is rotatably connected to the L-shaped plate 301. One end of the connecting rod 302 is located inside the mixing tank 101 and is fixedly connected to a gear 303. Multiple fixing plates 304 are fixedly connected to the inner wall of the rotating ring 203 near the end of the L-shaped plate 301. Each fixing plate 304 is positioned opposite to the other. A sleeve 305 is fixedly connected to the end of the rotating rod 201 and is fitted onto the side wall of the rotating rod 201 and connected to the inner wall of the top of the mixing tank 101. A gear ring 306 is fixedly connected to the side wall of the sleeve 305 and meshes with the gear 303. A motor 307 is fixedly connected to the side of the L-shaped plate 301 away from the mixing tank 101. The output end of the motor 307 is connected to the rotating rod 201. The rotating rod 201 is provided with a power transmission assembly for transmitting the driving force of the motor 307 to the connecting rod 302.
[0029] It should be noted that the rotating component is designed to facilitate the reverse rotation of each stirring plate 202 and mixing plate 204.
[0030] Please see Figure 3 The power transmission assembly shown in the figure includes a transmission disc 401 that is fixedly connected to the side walls of the rotating rod 201 and the connecting rod 302 respectively, and the two transmission discs 401 are connected by a transmission belt 402.
[0031] It should be noted that the power transmission component allows for the rotation of each stirring plate 202 and mixing plate 204 using a single motor 307, thereby saving energy expenditure.
[0032] Working principle: When mixing the waterproof powder used in the production of waterproof coating, the waterproof powder and other raw materials to be mixed are first fed into the mixing tank 101 through the feed pipe 102. Then, the motor 307 (model Y80M1-2, which is existing technology and will not be described in detail here) is started, which drives the rotating rod 201 to rotate. During the rotation of the rotating rod 201, the connecting rod 302 will be driven to rotate through the transmission action of the transmission disc 401 and the transmission belt 402, which in turn drives the gear 303 to rotate. Then, under the meshing transmission action of the gear 303 and the gear ring 306, the sleeve 305 will be driven to rotate.
[0033] During the rotation of the sleeve 305, the rotating ring 203 will be driven to rotate synchronously through the fixed plates 304. Since the gear 303 and the gear ring 306 change the rotation direction of the motor 307, the rotating rod 201 and the rotating ring 203 will rotate in opposite directions. At this time, the stirring plates 202 and the mixing plates 204 will rotate in opposite directions, which will drive the serrated plates 205 on both sides to rotate. During the rotation of the serrated plates 205, the serrated plates 205 can be inserted directly into the interior of the waterproof powder agglomerates like blades. When two adjacent serrated plates 205 rotate in opposite directions, the serrations will cut the agglomerates. This cutting action can effectively destroy the interaction force between the particles in the agglomerates, thereby destroying the air film formed by the waterproof powder particles with air due to their large specific surface area and high surface energy. This increases the chance of direct contact between the waterproof powder particles and other raw materials, making it easier for them to interpenetrate and blend, thereby improving the dispersion uniformity of the waterproof powder in other raw materials during mixing.
[0034] Simultaneously, as the stirring plate 202 and the mixing plate 204 rotate in opposite directions, when two adjacent stirring plates 202 and mixing plates 204 intersect, they will cause two adjacent serrated plates 205 to engage (see reference). Figure 5 This force is then used to generate shear force on the waterproof powder, thereby enhancing the destructive force on the air film on the surface of the waterproof powder.
[0035] Example 2
[0036] Please see Figure 2 This embodiment further illustrates Example 1. The mixing tank 101 shown in the figure is provided with a support assembly for supporting the rotating rod 201. The support assembly includes a support disk 501 rotatably connected to the mixing tank 101. The support disk 501 is connected to the end of the rotating rod 201 near the discharge pipe 103. The side of the support disk 501 away from the rotating rod 201 is provided with a plurality of support wheels 502. The side of the rotating ring 203 near the discharge pipe 103 is also provided with a plurality of support wheels 502. Each support wheel 502 is abutted against the inner wall of the bottom of the mixing tank 101.
[0037] It should be noted that by setting up the support components, the stability of the rotating rod 201 and the rotating ring 203 in the mixing tank 101 is improved by utilizing the rotational support of each support wheel 502.
