Description

Technical Field

[0001] The utility model belongs to the technical field of equipment for manufacturing redispersible latex powder, and specifically relates to a mixing device for manufacturing redispersible latex powder. Background Art

[0002] Redispersible latex powder products are water-soluble redispersible powders, which are divided into ethylene / vinyl acetate copolymers, vinyl acetate / versatate copolymers, acrylic acid copolymers, etc. The powder adhesive is made after spray drying, and polyvinyl alcohol is used as a protective colloid. This powder can be quickly redispersed into an emulsion after contact with water. Since redispersible latex powders have high bonding ability and unique properties, such as water resistance, construction performance and thermal insulation, their application range is extremely wide.

[0003] The prior art discloses a stirring and dissolving tank for producing redispersible latex powder with patent announcement number CN216704180U. When the above patent is in use, a motor drives a first conduit to rotate and stir the material in the tank body. While stirring, a fan conveys airflow to the stirring tube through the first conduit, the second conduit and the third conduit, and then blows air into the tank body through the small holes thereon, so that the stirring effect is good. However, in actual use, the following deficiencies still exist: from a practical point of view, the device only stirs and mixes the internal materials through the stirring tube at the bottom, so that the materials cannot be fully dissolved, and there will be bubbles containing dry powder in the discharged mixed liquid, which affects the mixing effect. Moreover, the device is not convenient to clean after the mixing of the materials is completed, which affects the next use.

[0004] Therefore, a mixing device for producing redispersible latex powder is needed to solve the problems in the prior art that the materials cannot be fully dissolved and are inconvenient to clean up. Utility Model Content

[0023] See also Figure 1-4 The utility model provides a mixing device for manufacturing redispersible latex powder, including a tank body 1, a mixing mechanism 2, a connecting mechanism 3, a feed pipe 4 and a discharge pipe 5. The mixing mechanism 2 is installed inside the tank body 1 through the connecting mechanism 3, the feed pipe 4 is fixedly connected to the upper back side of the tank body 1, and the discharge pipe 5 is fixedly connected to the lower front side of the tank body 1.

[0024] The mixing mechanism 2 is composed of a top plate 201, a sealing ring 202, a motor 203, a vertical shaft 204, a stirring rod 205, a stirring blade 206, a scraper 207 and a bottom plate 208. The sealing ring 202 is fixedly connected to the outside of the top plate 201, the motor 203 is fixedly connected to the top of the top plate 201, and handles are symmetrically arranged above the top plate 201. The vertical shaft 204 is connected to the output end of the motor 203, and the stirring rod 205 is symmetrically fixedly connected to the outside of the vertical shaft 204.

[0025] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth specifically explaining that the stirring blades 206 are arranged on the upper and lower sides of the stirring rod 205, and the stirring blades 206 include a rotating shaft and a fan blade, which is fixedly connected to the stirring rod 205 through the rotating shaft, and the fan blade is rotatably connected to the outside of the stirring rod 205.

[0026] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth to explain in detail that the scraper 207 is fixedly connected to the end of the stirring rod 205, and the side of the scraper 207 close to the inner wall of the tank body 1 is set as an arc surface, and the arc surface is in contact with the inner wall of the tank body 1;

[0027] By rotating the scraper 207, the materials adhering to the inner wall of the tank body 1 can be scraped off, thereby improving the mixing effect.

[0028] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth to explain in detail that the bottom plate 208 is fixedly connected to the bottom end of the vertical shaft 204, and a through hole 209 is opened on the bottom plate 208;

[0029] The material at the bottom of the tank body 1 is stirred through the bottom plate 208, and the provision of the through hole 209 can reduce the resistance during stirring and improve the stirring efficiency.

[0030] According to the above working process, it can be known that: through the setting of the mixing mechanism 2, the material inside the tank body 1 can be fully stirred and mixed, and the material adhering to the inner wall of the tank body 1 can be scraped off, and the stirring and mixing can be continued to improve the uniformity of the material mixing and the quality of the output material.

[0031] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the connecting mechanism 3 is composed of a positioning block 301, a slide plate 303, a protrusion 304, a spring 305, a push plate 306 and a limit block 307. A groove is symmetrically opened on the top surface of the tank body 1, the positioning block 301 is arranged inside the groove, and mounting grooves 302 are symmetrically opened on both sides of the groove. The protrusion 304 is symmetrically fixedly connected to both sides of the slide plate 303, and the slide plate 303 is slidably connected to the inside of the mounting groove 302 through the protrusion 304. The spring 305 is fixedly connected between the slide plate 303 and the mounting groove 302;

[0032] Under the elastic action of the spring 305 , the slide plate 303 is kept in the original state, and at the same time, the limit block 307 is driven to be stuck above the positioning block 301 to fix the position of the positioning block 301 .

[0033] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the push plate 306 is fixedly connected to the upper part of the slide plate 303, and the two sides of the push plate 306 are symmetrically provided with anti-slip grooves;

[0036] By receiving the limit block 307 into the interior of the slide slot, the fixation of the limit block 307 on the positioning block 301 can be released, so that the positioning block 301 can be easily pulled out.

[0037] This scheme has the following working process: when in use, the material is input into the tank body 1 through the feed pipe 4, and then the vertical shaft 204 is driven to rotate by the control motor 203, and the stirring blade 206 is driven to rotate by the stirring rod 205. The uniformity of material mixing is improved by the rotation of the fan blade. At the same time, the material adhering to the inner wall of the tank body 1 is scraped off by the scraper 207 at the end, so that the material is stirred and mixed again. At the same time, the bottom plate 208 at the bottom is rotated to stir the material below. The material can reduce the stirring resistance through the through hole 209, further improving the mixing effect. The mixed material is output through the discharge pipe 5. When the mixing mechanism 2 needs to be disassembled and cleaned, the push plate 306 is pushed outward, and the limit block 307 is driven to move by the slide plate 303 until the limit block 307 is retracted into the inside of the slide slot, and the positioning block 301 is released. Then, the top plate 201 is driven upward by the handle, and the mixing mechanism 2 can be disassembled for easy cleaning.

[0038] In summary: through the setting of the mixing mechanism 2, the material inside the tank body 1 can be fully stirred and mixed, and the material adhering to the inner wall of the tank body 1 can be scraped off, and the stirring and mixing can continue, thereby improving the uniformity of the material mixing and improving the quality of the output material; through the setting of the connecting mechanism 3, the mixing mechanism 2 and the tank body 1 can be disassembled and assembled without the aid of external tools, so that the mixing mechanism 2 can be dismantled and cleaned, thereby ensuring the cleanliness of the mixing mechanism 2, facilitating the next use of the device, and improving the practicality of the device.
