[0014] This safe feeding equipment for chemical production benefits from the structure of the grinding wheel. The motor drives the lead screw to rotate, which in turn drives the moving block to move within the chute. The moving block then drives the hollow block, which in turn drives the moving plate and connecting column. The connecting column then drives the grinding wheel, which grinds the chemical raw materials on the screening screen. The ground raw materials fall into the buffer hopper. When the grinding wheel moves to the end of the chemical material storage tank, one motor shuts off and the other starts, causing the lead screw to reverse and drive the grinding wheel to reciprocate within the chemical material storage tank. Compared to traditional safe feeding equipment for chemical production, which has weaker crushing capacity, this structure improves crushing capacity. Large pieces of material are less likely to cause blockages in the feeding hopper cone or conveying pipeline, reducing the frequency of downtime for unblocking. It also results in stronger reaction uniformity and reduced equipment wear.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical production equipment, and in particular, it is a safe feeding device for chemical production. Background Technology
[0002] In chemical production processes, material feeding is a crucial initial step, and its safety and accuracy have a profound impact on production efficiency and product quality. Traditional feeding methods often rely on manual operation, forcing operators to directly handle various hazardous chemicals. During the feeding process, powdery or granular raw materials easily generate dust, which not only pollutes the working environment but also, if it reaches a certain concentration in the air, can easily cause an explosion upon contact with a source of ignition, posing a significant safety hazard to production. Traditional chemical production safety feeding equipment can meet basic usage requirements, but its crushing capacity is weak, and large pieces of material easily form blockages in the feeding hopper cone or conveying pipelines, leading to frequent shutdowns for unblocking, poor reaction uniformity, and accelerated equipment wear and tear.
[0003] A search revealed Chinese patent documents (authorization announcement number CN221359773U). This utility model relates to the field of chemical production technology, specifically a safe feeding device for chemical production. It includes a reaction vessel with a sealed top cover. A drive motor rotates the auger blades to transport powder materials. Powder can be fed into the reaction vessel via a steel wire hose and a feeding pipe, achieving automated, fully enclosed feeding and preventing leakage of dust and harmful gases. While this equipment meets basic usage requirements, its crushing capacity is weak. Large pieces of material easily cause blockages in the feeding hopper cone or conveying pipeline, leading to frequent shutdowns for unblocking, poor reaction uniformity, and increased equipment wear.

[0026] like Figures 1 to 5 The diagram shows a safe feeding device for chemical production, including a chemical tank support column 1 for supporting the storage of raw materials for chemical production. A chemical material storage tank 202 is installed on the top of the chemical tank support column 1. Slide grooves 204 are provided on both sides of the chemical material storage tank 202. Two motors 3 are installed on the side of the chemical material storage tank 202. The output shafts of the two motors 3 are connected to lead screws 301 through couplings. A moving block 302 is connected to the outer periphery of the lead screw 301. The moving block 302 is slidably disposed inside the slide grooves 204. A hollow block 303 is welded to the side of the moving block 302.
[0027] A guide groove 305 is provided on the side of the hollow block 303. A spring 304 is connected inside the hollow block 303. Damping is provided between the spring 304 and the hollow block 303. One end of the spring 304 is connected to a moving plate 306. A connecting column 4 is welded to the side of the moving plate 306. A rotating column 401 is rotatably installed inside the connecting column 4. A grinding wheel 402 for grinding large particles of chemical raw materials is installed on the outer periphery of the rotating column 401. When one of the motors 3 is turned on, the motor 3 drives the lead screw 301 to rotate. The lead screw 301 drives the moving block 302 to move in the slide groove 204. The moving block 302 drives the hollow block 303 to move. The hollow block 303 drives the moving plate 306 and the connecting column. 4. The connecting column 4 drives the grinding wheel 402 to move. The grinding wheel 402 grinds the chemical raw materials on the screen 203. The ground chemical raw materials fall into the buffer hopper 205. When the grinding wheel 402 moves to the end of the chemical material storage box 202, one motor 3 is turned off and the other motor 3 is turned on. The lead screw 301 reverses and drives the grinding wheel 402 to reciprocate in the chemical material storage box 202. When it encounters large particles, the large particles squeeze the grinding wheel 402. The spring 304 pulls the moving plate 306. The moving plate 306 drives the connecting column 4 and the grinding wheel 402 to move towards the large particles, which can adapt to the grinding pressure between the grinding wheel 402 and the large particles.
[0028] The top of the chemical material storage tank 202 is equipped with a feeding box 2 for the safe feeding of chemical production raw materials. The top of the feeding box 2 is equipped with a sealing door 201. The vertical inner wall of the chemical material storage tank 202 is equipped with a screening screen 203 for screening chemical production raw materials. When the door 201 is opened, the raw materials for chemical production are added to the screening screen 203 through the feeding box 2. The screening screen 203 screens the incoming raw materials for chemical production. Raw materials that meet the size requirements enter the buffer hopper 205, while large-sized raw materials for chemical production remain on the screening screen 203. The bottom of the chemical material storage tank 202 is connected to the buffer hopper 205 for storing screened raw materials. The bottom of the buffer hopper 205 is connected to a dispersing box 106 for further dispersing chemical raw materials. The bottom of the dispersing box 106 is connected to a feeding pipe 105.
[0029] A conveyor frame 101 is provided on the side of the chemical tank support column 1. A spiral conveyor pipe 103 for conveying raw materials is installed on the top of the conveyor frame 101. The spiral conveyor pipe 103 is a commonly used material conveying equipment in chemical production. Its working principle is based on the rotational motion of the spiral blades and the interaction between the materials. A power unit 102 is installed at one end of the spiral conveyor pipe 103. The outer periphery of the spiral conveyor pipe 103 is connected to a discharge pipe 104 for discharging raw materials used in chemical production. The other end of the spiral conveyor pipe 103 is connected to the bottom of the feed pipe 105. Raw materials of the correct size enter the spiral conveyor pipe 103 through the dispersing box 106 and the feed pipe 105, and are finally discharged through the discharge pipe 104.
[0030] Working principle
[0031] This safe feeding equipment for chemical production operates as follows: First, open the door 201 and add the raw materials for chemical production through the feed box 2 onto the screening screen 203. The screening screen 203 screens the incoming raw materials, and materials that meet the required size enter the buffer hopper 205, while larger materials remain on the screening screen 203. Then, turn on one of the motors 3, which drives the lead screw 301 to rotate. The lead screw 301 moves the moving block 302 within the chute 204, which in turn moves the hollow block 303. The hollow block 303 then moves the moving plate 306 and the connecting column 4, which in turn moves the grinding wheel 402. The grinding wheel 402 grinds the raw materials on the screening screen 203. The material is ground, and the ground chemical raw material falls into the buffer hopper 205. When the grinding wheel 402 moves to the end of the chemical material storage box 202, one motor 3 is turned off and the other motor 3 is turned on. The lead screw 301 reverses, driving the grinding wheel 402 to reciprocate in the chemical material storage box 202. When it encounters large particles, the large particles squeeze the grinding wheel 402. The spring 304 pulls the moving plate 306. The moving plate 306 drives the connecting column 4 and the grinding wheel 402 to move towards the large particles. It can adapt to the grinding pressure between the grinding wheel 402 and the large particles. The material that meets the size requirements enters the spiral conveying pipe 103 through the dispersing box 106 and the feed pipe 105, and is finally discharged through the discharge pipe 104.
