Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical feeding technology, and in particular to a chemical safety feeding device. Background Technology
[0002] Chemical production is an important part of modern industry. Its core lies in transforming raw materials into chemicals or materials with specific properties through chemical reactions and physical processing to meet the diverse needs of industry and daily life. In the chemical production process, the feeding operation of materials is one of the key links for the smooth progress of chemical reactions. Usually, chemical logistics are put in, including powders that are put into the reaction vessel to carry out chemical reactions.
[0003] Traditionally, when manually feeding materials into a reactor, the material is usually directly poured into the tank through the feed pipe. However, the feed pipe of the reactor has a large gap, which results in fine powder being produced during the feeding process. In addition, the airflow disturbance caused by the falling material easily generates a large amount of dust. This dust is dispersed into the external environment through the feed pipe. If workers inhale it over a long period of time, it may cause respiratory diseases or chronic poisoning, seriously endangering their health and posing potential health risks and harms to surrounding workers. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a chemical safety feeding device to solve the problem that when feeding materials into a reaction vessel manually, the materials are usually directly put into the vessel through the feed pipe. However, the feed pipe of the reaction vessel has a large gap, which results in fine powder during the feeding process. In addition, the airflow disturbance during the falling of the material easily generates a large amount of dust.
[0005] To achieve the above objectives, this utility model provides a chemical safety feeding device, comprising a base plate, a reaction vessel fixedly connected to the top of the base plate, a mounting frame fixedly connected to the top of the base plate near the outer wall of the reaction vessel, a first threaded rod rotatably connected between the side walls of the mounting frame, a rotary motor fixedly connected to the top of the mounting frame, the output end of the rotary motor fixedly connected to the top end of the first threaded rod, a movable plate threadedly connected to the outer wall of the first threaded rod, a feeding storage tank fixedly connected to the middle part of the movable plate, connecting plates fixedly connected to both sides of the mounting frame, a stabilizing column fixedly connected between the opposite surfaces of the connecting plates and the mounting frame, the two sides of the movable plate slidably connected to the outer walls of the stabilizing column, a feeding pipe connected to the top of the reaction vessel, a discharge port connected to the bottom of the feeding storage tank, and a feeding mechanism for discharging materials provided inside the feeding pipe and the discharge port.
[0006] Preferably, the feeding mechanism includes an electric telescopic rod fixedly connected to the inside of the feeding pipe via a support plate. A top block is fixedly connected to the top of the electric telescopic rod. The top block is conical in shape. A sealing rubber ring is fixedly connected to the outer wall of the top of the feeding pipe. A fixing plate is fixedly connected to the inner wall of the feeding storage tank. A spring telescopic rod is fixedly connected to the bottom of the fixing plate. A top plate is fixedly connected to the bottom of the spring telescopic rod. The bottom of the top plate fits against the inner wall of the feeding storage tank. The top plate is conical in shape. An extrusion ring is fixedly connected to the outer edge of the discharge port.
[0007] Preferably, a spiral stirring rod is rotatably connected to the top of the fixed plate, the top end of the spiral stirring rod is rotatably connected to the top of the inner wall of the feeding storage tank, and a second motor is fixedly connected to the top of the feeding storage tank, with the output end of the second motor fixedly connected to the top end of the spiral stirring rod.
[0008] Preferably, a second threaded rod is threadedly connected to the side wall of the connecting plate, and a clamping plate is rotatably connected to the end of the second threaded rod near the reactor. Limiting rods are fixedly connected to both sides of the clamping plate, and the limiting rods slide through the side wall of the connecting plate.
[0009] Preferably, the clamping plate is arc-shaped and in contact with the side wall of the reactor.
[0010] Preferably, the top of the top block and the bottom of the top plate are adapted to each other.
[0011] The beneficial effects of this utility model are:
[0012] 1. A chemical safety feeding device. In this feeding mechanism, a compression ring at the bottom of the feeding storage tank compresses a sealing rubber ring. The sealing rubber ring folds under compression, and then an electric telescopic rod pushes a top block, which in turn pushes a top plate, connecting the feeding storage tank and the feeding pipe. At this point, the powder is fed into the reactor. The feeding process is sealed. After feeding, the compression ring releases its restraint on the sealing rubber ring, and the sealing rubber ring re-attaches to the outer wall of the top block, preventing dust from drifting to the outside through the feeding pipe. This ensures that dust does not drift to the outside during or after feeding, solving the problem of traditional manual feeding which easily generates large amounts of dust, leading to inhalation, respiratory illnesses, or chronic poisoning, seriously endangering health. It significantly improves the safety and environmental friendliness of the feeding process, ensuring sealing during and after feeding, and effectively avoiding the safety hazards and health risks caused by dust spillage during reactor feeding using traditional feeding devices.
[0013] 2. The chemical safety feeding device moves the clamping plate and the limiting rod to one side of the reactor by rotating the second threaded rod. Then the clamping plate will clamp the two sides of the reactor, preventing the reactor from tilting due to external forces during use. This effectively improves the safety of the reactor, avoids equipment damage, material leakage or personnel injury caused by tilting, and enhances the reliability of the entire production process and the safety of operators.

[0024] like Figures 1 to 5 As shown, a chemical safety feeding device includes a base plate 1, a reaction vessel 2 fixedly connected to the top of the base plate 1, a mounting frame 3 fixedly connected to the top of the base plate 1 near the outer wall of the reaction vessel 2, a first threaded rod 4 rotatably connected between the side walls of the mounting frame 3, a rotary motor 5 fixedly connected to the top of the mounting frame 3, the output end of the rotary motor 5 fixedly connected to the top of the first threaded rod 4, a movable plate 6 threadedly connected to the outer wall of the first threaded rod 4, a feeding storage tank 7 fixedly connected to the middle part of the movable plate 6, connecting plates 8 fixedly connected to both sides of the mounting frame 3, a stabilizing column 9 fixedly connected between the opposite surfaces of the connecting plate 8 and the mounting frame 3, the two sides of the movable plate 6 slidably connected to the outer wall of the stabilizing column 9, a feeding pipe 10 connected to the top of the reaction vessel 2, a discharge port 23 connected to the bottom of the feeding storage tank 7, and a feeding mechanism for feeding materials provided inside the feeding pipe 10 and the discharge port 23.
[0025] Further, see attached document. Figures 1 to 5 As shown, the feeding mechanism includes an electric telescopic rod 11 fixedly connected to the inside of the feeding pipe 10 via a support plate. A top block 12 is fixedly connected to the top of the electric telescopic rod 11. The top block 12 is conical in shape. A sealing rubber ring 13 is fixedly connected to the outer wall of the top of the feeding pipe 10. A fixing plate 14 is fixedly connected to the inner wall of the feeding storage tank 7. A spring telescopic rod 15 is fixedly connected to the bottom of the fixing plate 14. A top plate 16 is fixedly connected to the bottom of the spring telescopic rod 15. The bottom of the top plate 16 fits against the inner wall of the feeding storage tank 7. The top plate 16 is conical in shape. The top of the top block 12 and the bottom of the top plate 16 are matched. An extrusion ring 17 is fixedly connected to the outer edge of the discharge port 23.
[0026] During the operation of the feeding mechanism, the material is first conveyed into the feeding storage tank 7. When it is necessary to feed material into the reactor 2, the rotary motor 5 is started. The rotary motor drives the first threaded rod 4 to rotate, which in turn drives the moving plate 6 to move downward. The moving plate 6 drives the feeding storage tank 7 to move downward. At this time, the discharge port 23 is tightly fitted with the top of the feeding pipe 10, and the sealing rubber ring 13 of the discharge port 23 is squeezed and folded inward. Next, the electric telescopic rod 11 is started, which drives the top block 12 to move upward. When the top block 12 moves upward, it will squeeze the top plate 16, which in turn compresses the spring telescopic rod 15. At this time, the top plate 16 will not be completely fitted with the bottom of the feeding storage tank 7, forming a certain gap. With the help of gravity, the material in the feeding storage tank 7 falls through the gap into the feeding pipe 10 and is finally conveyed to the reactor 2.
[0027] After the material is conveyed, the rotary motor 5 and the electric telescopic rod 11 are started again. The electric telescopic rod drives the top block 12 to move downward. The rotary motor drives the moving plate 6 to move the feeding storage tank 7 upward through the first threaded rod 4. At this time, the extrusion ring 17 leaves the top of the feeding pipe 10. The sealing rubber ring 13 returns to its original position because it is no longer under the pressure of the extrusion ring 17 and re-fits with the top block 12, ensuring that the feeding pipe 10 is sealed again.
[0028] In this feeding mechanism, the sealing rubber ring 13 is squeezed by the compression ring 17 at the bottom of the feeding storage tank 7. After being squeezed, the sealing rubber ring 13 folds, and then the top block 12 is pushed by the electric telescopic rod 11. The top block 12 pushes the top plate 16, so that the feeding storage tank 7 and the feeding pipe 10 are connected to each other. At this time, the powder will be fed into the near reactor 2. The feeding process is in a sealed state. After the feeding is completed, the compression ring 17 releases the restriction on the sealing rubber ring 13, and the sealing rubber ring 13 re-attaches to the outer wall of the top block 12 to prevent dust from drifting to the outside through the feeding pipe 10. This ensures that dust will not drift to the outside during or after the feeding process, which significantly improves the safety and environmental protection of the feeding process. Its strong sealing performance and excellent dust control effect can effectively avoid the safety hazards and health risks caused by dust spillage during the feeding of the reactor 2 by traditional feeding devices.
[0029] Further, see attached document. Figure 3 As shown, a spiral stirring rod 18 is rotatably connected to the top of the fixed plate 14. The top end of the spiral stirring rod 18 is rotatably connected to the top of the inner wall of the feeding storage tank 7. A second motor 19 is fixedly connected to the top of the feeding storage tank 7. The output end of the second motor 19 is fixedly connected to the top end of the spiral stirring rod 18. When the material is conveyed into the feeding storage tank 7, the second motor 19 is started, and the second motor 19 drives the spiral stirring rod 18 to rotate. The spiral stirring rod 18 can then stir the material, making the material more evenly mixed.
[0030] Further, see attached document. Figure 2 As shown, a second threaded rod 20 is threadedly connected to the side wall of the connecting plate 8. A clamping plate 21 is rotatably connected to one end of the second threaded rod 20 near the reactor 2. Limiting rods 22 are fixedly connected to both sides of the clamping plate 21. The limiting rods 22 slide through the side wall of the connecting plate 8. The clamping plate 21 is arc-shaped and contacts the side wall of the reactor 2. When the reactor 2 is in use, rotating the second threaded rod 20 moves the clamping plate 21 and the limiting rods 22 to one side of the reactor 2. Then, the clamping plate 21 clamps both sides of the reactor 2, preventing the reactor 2 from tilting due to external forces during use. This effectively improves the safety of the reactor 2, avoids equipment damage, material leakage, or personnel injury caused by tilting, and enhances the reliability of the entire production process and the safety of operators.
