Description
Technical Field
[0001] This utility model relates to the field of acetylene preparation technology, specifically to a storage device for acetylene preparation. Background Technology
[0002] Acetylene, a gas with significant industrial applications, is widely used in metal welding, cutting, and certain chemical synthesis processes. Its preparation involves a chemical reaction between calcium carbide and water to produce acetylene gas. While this process is simple, it places extremely high demands on the storage conditions of calcium carbide. During storage, calcium carbide reacts violently with moisture in the air, releasing large amounts of heat and acetylene gas. Improper storage can easily lead to spontaneous combustion or even explosion. Existing hopper or silo structures cannot effectively isolate moisture from the air and lack necessary safety monitoring and alarm systems. Therefore, I propose a storage device for acetylene preparation to address these issues. Utility Model Content

[0005] Preferably, the outer surface of the cover plate has multiple ventilation holes, and the interior of the storage tank has multiple slots, with a gas sensor installed inside each slot.
[0006] Preferably, the storage tank has a feed inlet on its outer surface, a crushing box is installed on the outer surface of the storage tank, a crushing roller is rotatably installed inside the crushing box, and two motors B are installed on the outer surface of the crushing box. The output end of each motor B passes through the crushing box and is connected to the front end of the crushing roller.
[0007] Preferably, a storage box is installed on the upper surface of the support platform, and two connecting rods are fixed on the outer surface of the storage tank. An installation frame is installed on the outer surface of the two connecting rods and the inside of the storage box. Two rotating rods are rotatably installed inside the installation frame.
[0008] Preferably, the outer surfaces of the two rotating rods are connected to a conveyor belt for transmission, and a motor C is fixed to the outer surface of one of the mounting frames. The output end of the motor C passes through the mounting frame and is connected to the front end of one of the rotating rods.
[0009] Preferably, a water pump is installed on the bottom surface of the support platform, the input end of the water pump is connected to a pumping pipe, the output end of the water pump is connected to a water supply pipe, the end of the water supply pipe away from the water pump is connected to the outer surface of the reaction tank, a pump body is installed on the upper surface of the support platform, the output end of the pump body is connected to an output pipe, the input end of the pump body passes through the support platform and is connected to an input pipe, and the bottom end of the input pipe is connected to the outer surface of the reaction tank.
[0010] Preferably, the bottom surface of the support platform is fixed with four support legs, and the upper surface of the support platform is equipped with a controller.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention uses a motor A to drive a threaded rod to rotate, pushing a storage box to the top of the calcium carbide. This effectively reduces the contact space between the calcium carbide and the air. Since moisture in the air is a major risk factor for calcium carbide reaction, reducing the contact space helps prevent the calcium carbide from absorbing moisture. By using a storage box filled with hygroscopic drying powder, moisture in the air can be absorbed, creating a relatively dry environment inside the storage box. This helps keep the calcium carbide dry, avoiding the risk of spontaneous combustion or explosion due to moisture absorption, reducing waste caused by moisture agglomeration, and improving material utilization efficiency.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution: a storage device for acetylene preparation, including a support platform 1, a reaction tank 4 mounted on the outer surface of the support platform 1, a storage tank 5 mounted on the upper surface of the reaction tank 4, a top cover 6 mounted on the upper surface of the storage tank 5, an installation groove 7 and a fixing groove 10 opened inside the storage tank 5, a threaded rod 9 rotatably mounted inside the fixing groove 10, a motor A8 mounted inside the installation groove 7, the output end of the motor A8 passing through the installation groove 7 and extending into the interior of the fixing groove 10, the output end of the motor A8 being connected to the bottom end of the threaded rod 9, a storage box 11 threadedly connected to the outer surface of the threaded rod 9, a cover plate 12 mounted on the upper surface of the storage box 11, an electrically controlled valve B32 mounted at the bottom of the storage tank 5, and an electrically controlled valve A31 mounted at the bottom of the reaction tank 4.
[0021] The outer surface of the cover plate 12 has multiple ventilation holes, and the inside of the storage tank 5 has multiple slots 13. Each slot 13 is equipped with a gas sensor 14. When the gas sensor 14 detects an abnormal acetylene gas concentration, it indicates that the moisture absorption efficiency of the drying powder may be reduced. At this time, the drying powder can be replaced in time to maintain the dryness of the storage environment.
[0022] The storage tank 5 has a feed inlet 15 on its outer surface and a crushing box 16 installed on its outer surface. A crushing roller 18 is rotatably installed inside the crushing box 16. Two motors B17 are installed on the outer surface of the crushing box 16. The output end of each motor B17 passes through the crushing box 16 and is connected to the front end of the crushing roller 18. The crushing roller 18 is driven by the motor B17 to crush the calcium carbide. The crushed calcium carbide particles are more suitable for subsequent feeding and chemical reactions for acetylene preparation.
[0023] Among them, a storage box 19 is installed on the upper surface of the support platform 1, and two connecting rods 20 are fixed on the outer surface of the storage tank 5. The outer surface of the two connecting rods 20 and the inside of the storage box 19 are jointly installed with a mounting frame 21. Two rotating rods 24 are rotatably installed inside the mounting frame 21.
[0024] The outer surfaces of the two rotating rods 24 are connected to a conveyor belt 23 for transmission. A motor C22 is fixed on the outer surface of one of the mounting frames 21. The output end of the motor C22 passes through the mounting frame 21 and is connected to the front end of one of the rotating rods 24. The conveyor belt 23 is driven by the motor C22 to transport calcium carbide, eliminating the need for manual handling.
[0025] The support platform 1 has a water pump 25 installed on its bottom surface. The input end of the water pump 25 is connected to a water pumping pipe 27, and the output end of the water pump 25 is connected to a water delivery pipe 26. The end of the water delivery pipe 26 away from the water pump 25 is connected to the outer surface of the reaction tank 4. The support platform 1 has a pump body 29 installed on its upper surface. The output end of the pump body 29 is connected to an output pipe 30, and the input end of the pump body 29 passes through the support platform 1 and is connected to an input pipe 28. The bottom end of the input pipe 28 is connected to the outer surface of the reaction tank 4.
[0026] The support platform 1 has four support legs 3 fixed on its bottom surface, and a controller 2 is installed on its upper surface.
[0027] Working principle: In use, calcium carbide is first placed inside the storage box 19. Then, the controller 2 starts the motor C22, which drives the rotating rod 24 to rotate, thereby driving the conveyor belt 23. The conveyor belt 23 transports the calcium carbide inside the storage box 19. When the calcium carbide reaches the top of the conveyor belt 23, it falls into the crushing box 16. The motor B17 is started to drive the crushing roller 18 to rotate, crushing the calcium carbide inside the crushing box 16. The crushed calcium carbide particles are more suitable for subsequent feeding and the chemical reaction for acetylene preparation. The crushed calcium carbide falls into the storage tank 5 through the feed inlet 15 for storage. When the storage tank 5 is full of calcium carbide, the motor A8 is started, which drives the threaded rod 9 to rotate. The rotation then pushes the storage box 11 to the top of the calcium carbide. The storage box 11 is filled with drying powder to absorb moisture from the air, reducing the contact space between the calcium carbide and the air, and preventing the calcium carbide from reacting with the moisture in the air. When acetylene preparation is required, the electrically controlled valve B32 is opened, and the stored calcium carbide falls into the interior of the reaction tank 4. Then, the water pump 25 is started. The water pump 25 draws water through the water pumping pipe 27 and delivers it to the interior of the reaction tank 4 through the water delivery pipe 26. The water comes into contact with the calcium carbide to carry out a chemical reaction and generate acetylene gas. The pump body 29 drives the input pipe 28 to draw out the acetylene gas generated by the reaction and delivers it to the subsequent storage device through the output pipe 30. Finally, the electrically controlled valve A31 is opened to discharge the other materials generated by the reaction.
