[0002] Fine chemicals are a comprehensive and technology-intensive industry, including multi-step synthesis, separation technology, analysis and testing, performance screening, compounding technology, formulation development, commercial processing, application development and technical services. Fine chemical products are characterized by strong specialization, high added value and technology intensity, and are widely used in many fields such as pharmaceuticals, pesticides, dyes, coatings, electronic chemicals, and food additives. In the production process of fine chemicals, it is necessary to compound and mix a variety of raw materials.

[0003] Existing fine chemical material mixers have a simple mixing structure, which makes it difficult to meet the diverse mixing needs of fine chemical materials. In addition, some materials tend to adhere to the inner wall of the mixing tank, affecting the mixing effect. Furthermore, when feeding and pouring powder materials, they are prone to flying, which not only wastes materials but may also have adverse effects on the production environment and the health of operators. Therefore, there is a need to propose a material mixer for the fine chemical industry. Utility Model Content

[0004] The purpose of this invention is to provide a material mixer for the fine chemical industry to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material mixer for the fine chemical industry, comprising a support rod, a support ring fixedly connected to the inner side of the support rod, a mixing tank fixedly installed inside the support ring, a control switch fixedly installed outside the mixing tank, a discharge port provided at the lower end of the mixing tank, a discharge valve fixedly installed at the lower end of the discharge port, a tank cover fixedly installed at the upper end of the mixing tank, a feeding port fixedly installed at the upper end of the tank cover, a stirring mechanism fixedly installed at the upper end of the tank cover, a powder inlet fixedly installed at the upper end of the tank cover, a cylinder-type gate fixedly installed at the upper end of the powder inlet, a powder box fixedly installed at the upper end of the cylinder-type gate, a vacuum pump fixedly installed at the upper end of the tank cover, an air extraction pipe fixedly installed at the upper end of the powder box, and a suction hose fixedly installed outside the powder box;

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This material mixer for the fine chemical industry, through the combined use of a powder inlet, a cylinder-type gate, a powder box, a vacuum pump, an air extraction pipe, and a suction hose, can create negative pressure in the powder box by evacuating air through the vacuum pump and air extraction pipe during powder feeding. Then, the suction hose is used to draw the powder into the powder box. Afterward, the vacuum pump is turned off and the cylinder-type gate is opened to allow the powder to fall into the mixing tank. This reduces the labor intensity of workers during powder feeding, prevents powder from flying during dumping, improves the quality of the working environment, and is beneficial to worker protection, making it safer.

[0015] 2. This material mixer for the fine chemical industry, through the setting of the mixing mechanism, the scrapers on both sides of the frame-type mixing rod can scrape the powder and other materials that are prone to sticking to the inner wall of the mixing tank during mixing, thereby improving the mixing effect and product quality. The frame-type mixing rod can provide sufficient shear force and circulation force during mixing, generating horizontal circulation flow. Through the setting of disc and straight blades, it can generate meridional and axial flow during mixing, which can push the material in the central area to the periphery, and at the same time turn the material at the bottom upward, so that the material is fully mixed in the vertical direction. The combination of the two mixing structures can reduce dead corners during mixing and improve mixing efficiency and mixing quality. Attached Figure Description

A vacuum pump 13 is fixedly installed at the upper end of the tank cover 7. An extraction pipe 14 is fixedly installed at the upper end of the powder box 12. A suction hose 15 is fixedly installed on the outside of the powder box 12. Through the coordinated use of the powder inlet 10, cylinder-type gate 11, powder box 12, vacuum pump 13, extraction pipe 14, and suction hose 15, the system can control the powder feeding process using the vacuum pump 13 and extraction pipe 14. The powder hopper 12 is evacuated to create a negative pressure. The powder is then drawn into the hopper 12 using a suction hose 15. Afterwards, the vacuum pump 13 is turned off and the cylinder-type gate 11 is opened, allowing the powder to fall into the mixing tank 3. This reduces the labor intensity of workers during powder loading, prevents powder from flying during pouring, improves the worker's environment, and enhances worker safety. The mixing mechanism 9 includes a drive motor 901, a mixing shaft 902, a frame-type mixing rod 903, a scraper 904, a disc 905, and... The straight blade 906 and the stirring shaft 902 are fixedly installed at the lower end of the drive motor 901. A frame-type stirring rod 903 is fixedly installed on the outside of the stirring shaft 902. A scraper 904 is fixedly installed on the right side of the frame-type stirring rod 903. A disc 905 is fixedly installed on the outside of the stirring shaft 902. A straight blade 906 is fixedly installed on the outside of the disc 905.

[0025] Please see Figure 2-6In this embodiment, four support rods 1 are fixedly installed on the outer side of the support ring 2 to facilitate the fixation of the mixing tank 3. The feeding port 8 is connected to the mixing tank 3 to facilitate the feeding of liquid materials. The drive motor 901, the cylinder-type gate 11, and the vacuum pump 13 are all electrically connected to the control switch 4. The suction pipe 14 is fixedly installed between the powder box 12 and the vacuum pump 13 to facilitate the formation of negative pressure in the powder box 12.

The stirring shaft 902, the frame-type stirring rod 903, the scraper 904, the disc 905, and the straight blade 906 are all located inside the mixing tank 3 to facilitate the mixing of materials. Scrapers 904 are fixedly installed on both sides of the frame-type stirring rod 903. The frame-type stirring rod 903 has an overall "U"-shaped structure. The scrapers 904 on both sides of the frame-type stirring rod 903 can scrape the powder and other materials that are easy to stick to the inner wall of the mixing tank 3 during stirring, thereby improving the mixing effect and product quality. Two discs 905 are fixedly installed on the outside of the stirring shaft 902, and eight straight blades 906 are fixedly installed on the outside of the discs 905.

Then, through the coordinated use of the powder inlet 10, the cylinder-type gate 11, the powder box 12, the vacuum pump 13, the air extraction pipe 14, and the suction hose 15, the powder box 12 is evacuated by the vacuum pump 13 and the air extraction pipe 14, creating a negative pressure. The suction hose 15 then draws the powder into the powder box 12. Afterward, the vacuum pump 13 is turned off and the cylinder-type gate 11 is opened, allowing the powder to fall into the mixing tank 3. This reduces the labor intensity of workers during powder feeding, prevents powder from flying during pouring, improves the working environment, and is safer for workers. Then, the mixing mechanism 9... The frame-type stirring rod 903 has scrapers 904 on both sides that can scrape the powder and other materials that are prone to sticking to the inner wall of the mixing tank 3 during mixing, thereby improving the mixing effect and product quality. The frame-type stirring rod 903 can provide sufficient shear force and circulation force during mixing, generating a horizontal circulation flow. The disc 905 and straight blades 906 can generate radial and axial flow during mixing, which can push the material in the central area to the periphery and also turn the material at the bottom upward, so that the material is fully mixed in the vertical direction. The combination of the two mixing structures can reduce dead corners during mixing, improve mixing efficiency and mixing quality. After mixing is completed, the discharge valve 6 is opened to discharge the material.
