[0001] This utility model relates to a polyurethane processing and mixing device, and more particularly to a polyurethane processing and mixing device applied in the field of polyurethane processing. Background Technology

[0002] Polyurethane is a polymer material with repeating urethane groups in its main chain. It is made by polyol and polyisocyanate through a polycondensation reaction. Its properties are between those of plastics and rubber. It has excellent wear resistance, elasticity, oil resistance and adjustable mechanical properties. By changing the raw material ratio, it can be made into soft or hard products. The diversity of polyurethane makes it the "fifth largest plastic", covering multiple fields such as industry, medical and daily life.

[0003] Isocyanates and polyols are raw materials for the production of polyurethane. The key to polyurethane production lies in the mixing quality of isocyanates and polyols. When the two are not mixed evenly, the hardness, strength, and cell structure of the final polyurethane will be severely reduced. Utility Model Content

[0004] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that the core of polyurethane production and processing lies in the mixing quality of isocyanate and polyol. When the two are not mixed evenly, it will lead to a serious decline in the hardness, strength and cell structure performance of the final polyurethane.

[0005] To solve the above problems, this utility model provides a polyurethane processing and mixing device, including a mixing box, wherein a pair of vertical pipes are fixedly inserted inside the mixing box; Each of the two vertical pipes is fixedly connected to a feed pipe on the side away from each other. The feed pipe is connected to the vertical pipe. Several mixing rods are fixedly connected to the inner wall of the vertical pipe. The bottom ends of the pair of vertical pipes are fixedly connected to the same discharge pipe, the top of the discharge pipe is fixedly connected to a motor, the output end of the motor is fixedly connected to a connecting shaft, and a plurality of mixing rods are fixedly connected to the surface of the connecting shaft. A circular plate is fixedly connected inside the mixing box. A second motor is fixedly connected to the circular plate. A connecting block is fixedly connected to the output end of the second motor. Several stirring rods are fixedly connected to the surface of the connecting block.

[0006] As a further improvement of this application, the bottom of the stirring rod abuts against the top of the circular plate, and the top of the vertical tube extends out from the mixing chamber.

[0007] As a further improvement of this application, a material receiving groove is provided on the surface of the mixing box, and a sealing plate is fixedly connected inside the material receiving groove by bolts.

[0008] As a further improvement of this application, an installation groove is provided on the surface of the sealing plate, and an observation plate is fixedly connected inside the installation groove. The observation plate is made of transparent material.

[0009] As a further improvement of this application, there is a gap between the top of the circular plate and the bottom of the discharge pipe, and the end of the feed pipe away from the vertical pipe is inclined upward.

[0010] As another improvement of this application, an air pump is fixedly connected to the top of the vertical pipe, the air outlet of the air pump is connected to the vertical pipe, and an insertion groove is provided on the surface of the mixing box, and a water receiving box is movably inserted into the insertion groove.

[0011] As a further improvement to this application, a handle is fixedly connected to the surface of the water receiving tank, a water level sensor and a controller are installed inside the water receiving tank, and a light panel is fixedly connected to the surface of the water receiving tank. The light panel, the water level sensor and the controller are all electrically connected to each other by wires.

[0012] This application has the following beneficial effects when used: 1. In use, this application uses a mixing rod to break up the materials to prevent them from clumping, then uses a mixing bar to break up and mix different materials, and finally uses a stirring rod to stir and spread the mixed materials, thereby further improving the uniformity of the material mixture and improving the mixing effect of isocyanate and polyol.

[0013] 2. When cleaning the inside of the mixing tank, water can be injected into the vertical pipe through the feed pipe. At the same time, the air pump is started to blow air into the vertical pipe. This not only speeds up the flow of water in the vertical pipe but also agitates the inside of the pipe, thereby increasing the drying speed inside the device. It also blows away the material adhering to the inner wall of the device, separating it from the inner wall. The mixture of water and material is then filtered through the filter holes for material recovery. The water then passes through the filter holes into the water receiving tank for temporary storage, which facilitates cleaning of the inside of the device and material recovery, and also allows for the recycling of water resources.

Detailed Implementation

[0016] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0017] First implementation method: Figure 1-3 and Figure 5 A polyurethane processing mixing apparatus is shown, including a mixing chamber 1, wherein a pair of vertical pipes 2 are fixedly inserted inside the mixing chamber 1; Each of the two vertical pipes 2 is fixedly connected to a feed pipe 3 on the side away from each other. The feed pipe 3 communicates with the vertical pipe 2. Several mixing rods 4 are fixedly connected to the inner wall of the vertical pipe 2. The bottom ends of the pair of vertical pipes 2 are fixedly connected to the same discharge pipe 5, the top of the discharge pipe 5 is fixedly connected to a motor 6, the output end of the motor 6 is fixedly connected to a connecting shaft 7, and a plurality of mixing rods 8 are fixedly connected to the surface of the connecting shaft 7. A circular plate 9 is fixedly connected inside the mixing box 1. A motor 10 is fixedly connected to the circular plate 9. A connecting block 11 is fixedly connected to the output end of the motor 10. Several stirring rods 12 are fixedly connected to the surface of the connecting block 11.

[0018] The bottom of the stirring rod 12 abuts against the top of the circular plate 9, and the top of the vertical tube 2 extends out from the mixing box 1.

[0019] A material taking groove 13 is provided on the surface of the mixing box 1, and a sealing plate 14 is fixedly connected inside the material taking groove 13 by bolts.

[0020] An installation groove is provided on the surface of the sealing plate 14, and an observation plate 15 is fixedly connected inside the installation groove. The observation plate 15 is made of transparent material, which facilitates personnel to observe the process of mixing isocyanate and polyol.

[0021] There is a gap between the top of the circular plate 9 and the bottom of the discharge pipe 5. The end of the feed pipe 3 away from the vertical pipe 2 is inclined upward so that the material slides from the feed pipe 3 into the vertical pipe 2.

[0022] This solution can be implemented. When using it, motor 6 and motor 10 need to be started so that the connecting shaft 7, mixing rod 8 and stirring rod 12 can rotate. The material is fed into the feed pipe 3 and slid from the feed pipe 3 into the vertical pipe 2. After the material enters the vertical pipe 2, during its downward movement, the mixing rod 4 can break up the clumps of material. When different materials enter the discharge pipe 5 from a pair of vertical pipes 2, the mixing rod 8 is used to mix and stir the materials for the first time. After mixing, the material will fall from the discharge pipe 5 onto the circular plate 9. Then, the material is stirred and pushed apart using the stirring rod 12. This not only prevents the material from piling up and blocking the bottom of the discharge pipe 5, but also allows the material to be stirred again to ensure thorough mixing. In summary, when this application is used, the material is dispersed by the mixing rod 4 to prevent it from clumping, then the different materials are dispersed and mixed by the mixing rod 8, and finally the mixed material is stirred and spread by the stirring rod 12 to further improve the uniformity of the material mixture and improve the mixing effect of isocyanate and polyol.

[0023] Second implementation method: This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below: Figure 3-4 The top of the vertical pipe 2 is fixedly connected to an air pump 16, the air outlet of the air pump 16 is connected to the vertical pipe 2, the surface of the mixing box 1 is provided with an insertion groove 17, the inside of the insertion groove 17 is movably inserted with a water receiving box 18, and the circular plate 9 is provided with filter holes.

[0024] A handle is fixedly connected to the surface of the water receiving tank 18. A water level sensor and a controller are installed inside the water receiving tank 18. A light panel 19 is fixedly connected to the surface of the water receiving tank 18. The light panel 19, the water level sensor, and the controller are all electrically connected by wires. When the water level in the water receiving tank 18 reaches the set value of the water level sensor, the controller activates the light panel 19 to light up, so as to send a warning signal to remind personnel to take out the water in the water receiving tank 18 in time.

[0025] This solution allows water to be injected into the vertical pipe 2 from the feed pipe 3 while cleaning the inside of the mixing tank 1. At the same time, the air pump 16 is started to blow air into the vertical pipe 2, which not only speeds up the flow of water in the vertical pipe 2, but also agitates the inside of the vertical pipe 2. This not only increases the drying speed inside the device, but also agitates the material adhering to the inner wall of the device, separating it from the inner wall. The mixture of water and material is then filtered through the filter holes for material recovery. Subsequently, the water passes through the filter holes into the water receiving tank 18 for temporary storage, which facilitates personnel cleaning the inside of the device and recovering materials, and also allows for the recycling of water resources.
