[0002] Chemical industry is the abbreviation of "chemical process", "chemical industry" and "chemical engineering". Any technology that uses chemical methods to change the composition and structure of substances or synthesize new substances belongs to chemical production technology, that is, chemical process. The resulting products are called chemicals or chemical products. In the chemical industry, materials need to be mixed in a certain proportion to achieve chemical reactions to obtain corresponding products. In the process of feeding materials, material feeding machinery is generally used to feed materials in a certain amount;

[0003] When the existing chemical feeding device feeds powdered materials, since the powdered materials are light, it is easy for the materials to leak and generate dust due to environmental and feeding factors. This not only wastes resources, but also feeds in a high-density dust environment, which is very harmful to the health of the workers. Therefore, we propose a chemical feeding device. Utility Model Content

[0029] Example 1

[0030] like Figure 1-3 As shown, the utility model provides a technical solution: a chemical feeding device, including an equipment box 1, a box cover 2 is arranged at the top of the equipment box 1, a recovery area 3 is formed between the equipment box 1 and the box cover 2, and the recovery area 3 can recover dust, and an exhaust fan 4 and a servo motor 5 are respectively arranged at the top of the box cover 2 near the front and back sides, and the exhaust fan 4 extracts the air inside the recovery area 3 through the exhaust port 401, and the servo motor 5 can drive the stirring rod 501 to rotate, and the exhaust port 401 is extended to the recovery area 3 from the output end of the exhaust fan 4. A feeding area 6 is provided inside the equipment box 1 and below the recovery area 3. The feeding area 6 is responsible for storing materials, and a first filter screen 101 is arranged at the top of the feeding area 6. The first filter screen 101 can prevent large or agglomerated materials from entering the feeding area 6 for feeding, and the servo motor 5 The output end of the box passes through the first filter screen 101 and extends to the feeding area 6, where a stirring rod 501 is provided. The stirring rod 501 can ensure the uniformity of feeding. A feeding pipe 7 is provided just below the feeding area 6 and inside the equipment box 1. The feeding pipe 7 is responsible for feeding. The feeding pipe 7 extends out of the periphery of the equipment box 1 and is provided with a valve 8. The valve 8 can be closed when the feeding is finished or interrupted. A plurality of recovery holes 201 are equidistantly penetrated on the outer wall of the box cover 2, where air and material powder can enter. A second filter screen 202 is provided on the inner wall of the box cover 2 corresponding to the plurality of recovery holes 201, where the second filter screen 202 can filter impurities in the air. A third filter screen 402 is provided at the bottom of the exhaust port 401, where the third filter screen 402 can prevent the material powder from being sucked away by the exhaust fan 4.

[0031] Example 2

[0032] like Figure 1-3As shown, a box door 102 is provided on the front of the equipment box 1, and an observation window 103 and a handle 104 are respectively provided near the top and the bottom of the box door 102. The box door 102 is hingedly connected to the equipment box 1. When feeding is needed, the box door 102 can be opened by the handle 103 to put in the material. The observation window 104 can be used to observe the internal working conditions of the equipment during operation. The exhaust fan 4 and the servo motor 5 are fixed to the box cover 2 by bolts. When the device is feeding, the equipment box 1 will inevitably have a slight shake accompanied by the operation of the servo motor 5. The bolt fixing method can increase the overall stability of the equipment. The feeding area 6 is a funnel-shaped structure design. When the material enters the feeding area 6 to be fed, the feeding area 6 with a funnel-shaped structure design can feed the material more quickly and conveniently. The mesh numbers of the first filter 101, the second filter 202 and the third filter 402 are 150, 100 and 50 respectively. When the device is working, the first filter 101 can separate larger or agglomerated materials in the material to prevent them from affecting the chemical reaction. The second filter 202 can filter out impurities entering through the recovery hole 201 when the exhaust fan 4 draws away the air in the recovery area 3, and only passes the material powder. The third filter 402 can prevent the material powder from being drawn away by the exhaust fan 4 through the exhaust port 401. A controller 9 is provided on the right side of the equipment box 1 near the top. The controller 9 is electrically connected to the exhaust fan 4 and the servo motor 5. The feeding pipe 7 is facing near the bottom. When feeding, the feeding pipe 7 facing the bottom can output the material more conveniently.

[0033] The working process of the utility model is as follows: when using a chemical feeding device, firstly, when feeding materials, the box door 102 is opened to put the materials to be fed, the materials pass through the first filter screen 101, the controller 9 turns on the servo motor 5, the servo motor 5 drives the stirring rod 501 to rotate, and the materials enter the feeding pipe 7 at a uniform speed under the stirring of the stirring rod 501. In this process, it is inevitable that powder leakage will cause dust. At this time, the exhaust fan 4 is turned on by the controller 9, and the exhaust fan 4 draws away the air inside the recovery area 3 through the exhaust port 401, and the external air and The material powder enters the recovery area 3 through the recovery hole 201, and the second filter screen 202 filters out the impurities entering through the recovery hole 201 and only passes the material powder. The third filter screen 402 can prevent the material powder from being sucked away by the exhaust fan 4 through the exhaust port 401. After the exhaust fan 4 has worked for a period of time, the controller 9 turns off the exhaust fan 4, and the material powder falls into the first filter screen 101 for feeding, which is convenient for recycling. Compared with the existing chemical feeding device, it reduces the waste of materials, ensures the safety of the staff, and improves the safety and convenience of the chemical feeding device.
