[0002] There are many types of chemical raw materials with a wide range of uses. There are as many as 5 to 7 million kinds of chemical products in the world, and more than 100,000 kinds are sold and circulated on the market. In addition, more than 1,000 new chemical products are launched every year, of which 150 to 200 are considered carcinogens. In the process of chemical production, a variety of chemical raw materials are usually required to react to synthesize the desired products.

[0003] In existing chemical raw material automatic feeding systems, some viscous or easily crystallizing materials tend to adhere to the inner wall of the feeding tank during the feeding process. Over time, these accumulated materials not only reduce the effective volume of the feeding tank and affect the accuracy of feeding, but may also become a breeding ground for bacteria, mold and other microorganisms, which can adversely affect subsequent chemical reactions. Therefore, we propose an automatic feeding device for chemical product production. Utility Model Content

[0025] Please see Figure 1-4 This utility model provides a technical solution: an automatic feeding device for chemical product production, comprising:

[0026] A chemical production mixing tank 1 has a feed pipe 15 fixedly connected to its top, and the feed pipe 15 communicates with the interior of the chemical production mixing tank 1.

[0027] The material tank cleaning structure is located on the chemical production mixing tank 1.

[0028] The material tank cleaning structure includes two auxiliary material storage tanks 2, two solenoid valves 5, two tank covers 16, a drive motor 3, a belt 4, and a rotating shaft 7. The two auxiliary material storage tanks 2 are fixedly installed on the top of the chemical production mixing tank 1, and the two auxiliary material storage tanks 2 are connected to the interior of the chemical production mixing tank 1. The two solenoid valves 5 are fixedly installed on the discharge pipes of the corresponding auxiliary material storage tanks 2. The two tank covers 16 are fixedly installed on the top of the corresponding auxiliary material storage tanks 2. The drive motor 3 is fixedly installed on the top of the chemical production mixing tank 1. The rotating shaft 7 is rotatably connected to the top of the chemical production mixing tank 1. The belt 4 is driven and sleeved on the output end of the drive motor 3 and the outer surface of the rotating shaft 7.

[0029] The material tank cleaning structure also includes two toothed rings 12, two second cleaning scrapers 13, and a gear 6. The inner walls of the two auxiliary material storage tanks 2 are provided with annular grooves 14, and the outer surfaces of the two auxiliary material storage tanks 2 are provided with transmission grooves 8. The two transmission grooves 8 are connected to the interior of the corresponding annular grooves 14. The two toothed rings 12 are slidably connected to the interior of the corresponding annular grooves 14. The two second cleaning scrapers 13 are fixedly connected to the interior of the corresponding toothed rings 12. The gear 6 is fixedly sleeved on the outer surface of the rotating shaft 7. The two toothed rings 12 are meshed with the gear 6 inside the corresponding transmission grooves 8.

[0030] The bottom end of the rotating shaft 7 extends into the interior of the chemical production mixing tank 1. Multiple stirring blades 9 are fixedly connected to the outer surface of the rotating shaft 7. A first cleaning scraper 10 is fixedly connected to the outer surface of the rotating shaft 7. The first cleaning scraper 10 slides in contact with the inner wall of the chemical production mixing tank 1. A discharge screw 11 is fixedly connected to the bottom end of the rotating shaft 7. The discharge screw 11 is located at the discharge port of the chemical production mixing tank 1.

[0031] Furthermore, when using this device, the drive motor 3 is started by connecting an external power source. Since pulleys are fixedly sleeved on both the output end of the drive motor 3 and the outer surface of the rotating shaft 7, the drive motor 3 drives the rotating shaft 7 to rotate via the belt 4. The rotation of the rotating shaft 7 drives the gear 6 to rotate, and the rotation of the gear 6 drives the two gear rings 12 meshing with it to slide in the corresponding annular grooves 14. The movement of the two gear rings 12 drives the corresponding second cleaning scraper 13 to rotate. Since the second cleaning scraper 13 slides in contact with the inner wall of the auxiliary material storage tank 2, the second cleaning scraper 13 can... The chemical raw materials adhering to the inner wall of the auxiliary material storage tank 2 are cleaned so that the second cleaning scraper 13 can agitate the discharge point of the auxiliary material storage tank 2, thereby preventing the powdered chemical raw materials from clogging at the discharge point. The rotation of the rotating shaft 7 will drive multiple stirring blades 9 to agitate the chemical raw materials in the chemical production mixing tank 1. The rotation of the rotating shaft 7 will also drive the first cleaning scraper 10 to rotate, so that the first cleaning scraper 10 can clean the material adhering to the inside of the chemical production mixing tank 1, thereby facilitating the discharge screw 11 to discharge the agitated material. A control valve is provided at the discharge end of the chemical production mixing tank 1.

[0032] With the cooperation of the rotating shaft 7, belt 4, gear 6, two toothed rings 12 and two second cleaning scrapers 13, the gear 6 can drive the two toothed rings 12 to slide synchronously, so that the two toothed rings 12 can drive the corresponding second cleaning scrapers 13 to clean the chemical raw materials attached to the inner wall of the auxiliary material storage tank 2, avoid the chemical raw materials from adhering to the inner wall of the auxiliary material storage tank 2, and further improve the accuracy of chemical raw material feeding.

[0033] Working principle: The drive motor 3 is started by connecting to an external power source. Since the output end of the drive motor 3 and the outer surface of the rotating shaft 7 are both fixedly fitted with pulleys, the drive motor 3 will drive the rotating shaft 7 to rotate via the belt 4. The rotation of the rotating shaft 7 will drive the gear 6 to rotate. The rotation of the gear 6 will drive the two toothed rings 12 meshing with it to slide in the corresponding annular grooves 14. The movement of the two toothed rings 12 will drive the corresponding second cleaning scraper 13 to rotate. Since the second cleaning scraper 13 slides in contact with the inner wall of the auxiliary material storage tank 2, the second cleaning scraper 13 can clean the chemical raw materials attached to the inner wall of the auxiliary material storage tank 2. The second cleaning scraper 13 can agitate the discharge point of the auxiliary material storage tank 2, thereby preventing the powdered chemical raw materials from clogging at the discharge point.
