Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a continuous feeding device for a dry acetylene generator. Background Art

[0002] In the field of chemical production, especially in the production process of acetylene, as a core device, the performance and efficiency of the dry acetylene generator are directly related to the operation stability of the entire production line and the product quality; acetylene, as an important chemical raw material, is widely used in multiple industries such as synthetic rubber, plastics, and metal welding. Therefore, improving the efficiency and quality of acetylene production has significant economic significance.

[0003] Chinese Utility Model Patent CN 220780229 U discloses a processing device for producing acetylene gas based on dry acetylene. By installing a generator body, a raw material cylinder, a protective cover, a support frame, a support rod, and a rotating device, when filtering the calcium carbide powder raw material, it can prevent the accumulation of calcium carbide powder raw material during the feeding process, making the feeding uniform and continuous. At the same time, the feeding flow rate of the calcium carbide powder raw material can be adjusted according to the usage needs, improving the performance of the acetylene generator. However, when the calcium carbide powder raw material with larger particles passes through the rotating device, it cannot be discharged and broken, and there is a problem of caking and blockage before feeding, resulting in unsmooth feeding. When dredging, acetylene gas will leak. Summary of the Invention

[0004] The technical problem to be solved by the utility model is how to solve the problem of caking and blockage before feeding of the dry acetylene generator. The purpose of the utility model is to provide a continuous feeding device for a dry acetylene generator that can pre-treat the raw materials entering the acetylene generator body to prevent the caking and blockage of calcium carbide powder.

[0005] The technical solution adopted by the utility model is: a continuous feeding device for a dry acetylene generator, including an acetylene generator body. A feeding pipe is installed at the top of the acetylene generator body. One end of the feeding pipe is fixedly connected to a conveying pipe. One end of the conveying pipe is fixedly connected to a motor. A screw conveyor is rotatably connected inside the conveying pipe. The output end of the motor is fixedly connected to one end of the screw conveyor. The top of the conveying pipe is fixedly connected to a feeding hopper. A grinding mechanism is installed inside the feeding hopper. The grinding mechanism includes: a fixed grinding disc and a rotating grinding disc. The fixed grinding disc is fixedly connected inside the feeding hopper, and the rotating grinding disc is installed at the bottom of the fixed grinding disc.

[0006] Using the continuous feeding device for a dry acetylene generator provided by the utility model can obtain the following beneficial effects:

[0007] (1) Improve the feeding efficiency and stability: By introducing structures such as conveying pipes and augers, the continuous and stable conveying of raw materials is achieved, avoiding the blockage and material breakage problems that may occur in traditional feeding methods. At the same time, the setting of the grinding mechanism effectively reduces the particle size of the raw materials and improves the efficiency of the acetylene reaction.

[0008] (2) Effectively prevent caking: The combined application of the grinding mechanism and the anti-caking technology can effectively break the caking formed by the raw materials during transportation and prevent the generation of new caking. This not only ensures the smoothness of the feeding process but also improves the quality and stability of acetylene production.

[0009] Preferably, the grinding mechanism further includes: a connecting rod, a driven bevel gear, a transmission shaft, a driving bevel gear, a driven sprocket, a driving sprocket, a feeding hole, a V-shaped rod, and a cross bar. A cross bar is fixedly connected inside the feeding hopper. The middle of the cross bar is rotatably connected with a connecting rod. One end of the connecting rod is fixedly connected to the bottom end of the rotating grinding disc. The bottom end of the connecting rod is fixedly connected with a driven bevel gear. One side of the feeding hopper is rotatably connected with a transmission shaft. One end of the transmission shaft is fixedly connected with a driving bevel gear. The other end of the transmission shaft is fixedly connected with a driven sprocket. The driving bevel gear is meshed with the driven bevel gear. The output end of the motor is fixedly connected with a driving sprocket. The driving sprocket and the driven sprocket are connected by a chain drive. One side of the fixed grinding disc is provided with a feeding hole. The top end of the connecting rod extends out of the fixed grinding disc and is fixedly connected with a V-shaped rod. During the grinding process, the raw materials to be ground fall into the conveying pipe through the feeding hole. At this time, the motor also drives the auger to rotate in the conveying pipe. The rotation of the auger generates a pushing force to continuously and stably convey the raw materials to the feeding pipe of the acetylene generator body. The design of the V-shaped rod helps to dial the raw materials accumulated above the fixed grinding disc into the grinding area to prevent the raw materials from caking or blocking in the feeding hopper. At the same time, the triangular cross-section of the cross bar also helps to reduce the accumulation of raw materials at the top and improve the feeding efficiency.

[0010] Preferably, the mutually approaching sides of the fixed grinding disc and the rotating grinding disc are both provided with grinding lines. The design of the grinding lines helps to achieve the uniform grinding of the raw materials and reduce the particle size difference in the raw materials.

[0011] This helps to ensure the uniformity and stability of the acetylene generation reaction and improve the purity and quality of the acetylene product. At the same time, uniform grinding also helps to reduce the generation of by-products and improve the product yield and economic benefits.

[0012] Preferably, the top end of the cross bar is designed as an equilateral triangle with the vertex protruding upward, which can break the natural accumulation trend of the raw materials above the cross bar.

[0013] When the raw materials fall, due to the guiding effect of the triangle, the raw materials are more likely to slide down along the inclined plane of the triangle rather than accumulate above the cross bar. This can effectively prevent the blockage and accumulation of raw materials during the feeding process and ensure the smoothness of feeding.

[0014] Preferably, the turning point of the V-shaped lever coincides with the center of the feeding hole. The design of the V-shaped cross bar enables the raw materials to slide down more smoothly along the V-shaped channel to the grinding area.

[0015] This design reduces the possibility of raw materials accumulating above the grinding disc, thereby improving the feeding efficiency and ensuring that the raw materials can continuously and stably enter the grinding area for crushing and refining.

[0016] Preferably, a discharge pipe is installed at the bottom end of the acetylene generator body. The design of the discharge pipe enables the carbide slag after the reaction to be quickly and smoothly discharged from the acetylene generator.

[0017] It avoids the long-term residence and accumulation of carbide slag in the generator, provides space for the feeding and reaction of new raw materials, and thus improves the continuity and efficiency of acetylene production.

[0018] Preferably, support columns are equidistantly installed at the bottom end of the acetylene generator body. There are four support columns designed, and the support columns are made of stainless steel.

[0019] It has high strength to support the entire acetylene generator body and also avoids deformation when the support columns are collided.

[0020] Preferably, transfer hoppers are respectively fixedly installed at the top end of the feeding hopper. Solenoid valves are installed between the feeding hopper and the transfer hoppers and between the two transfer hoppers. Inlet pipes are installed at one end of the feeding hopper and the two transfer hoppers, and nitrogen enters through the inlet pipes. Exhaust pipes are installed at the other end of the feeding hopper and the two transfer hoppers. The exhaust pipes are used to displace the acetylene gas inside the feeding hopper and the two transfer hoppers. One feeding hopper and two transfer hoppers are provided, and they feed separately. When the lower feeding hopper conveys materials, the upper transfer hopper is closed and does not feed. When this transfer hopper feeds, the transfer hopper above it is closed to avoid simultaneous feeding and loading, thus preventing the leakage of acetylene gas. In addition, nitrogen inlet pipes are equipped to displace the acetylene gas in the transfer hoppers and the feeding hopper, reducing the risk of acetylene gas contacting oxygen.

[0030] Embodiment 1

[0031] The following is further described in conjunction with specific embodiments. Refer to Figures 1-5 As shown, this embodiment is a continuous feeding device for a dry acetylene generator, including an acetylene generator body 1. A feeding pipe 2 is installed at the top of the acetylene generator body 1. One end of the feeding pipe 2 is fixedly connected to a conveying pipe 3. One end of the conveying pipe 3 is fixedly connected to a motor 4. A screw conveyor 5 is rotatably connected inside the conveying pipe 3. The output end of the motor 4 is fixedly connected to one end of the screw conveyor 5. The top of the conveying pipe 3 is fixedly connected to a feeding hopper 6. A grinding mechanism 7 is installed inside the feeding hopper 6. The grinding mechanism 7 includes: a fixed grinding disc 71 and a rotating grinding disc 72. The fixed grinding disc 71 is fixedly connected inside the feeding hopper 6. The rotating grinding disc 72 is installed at the bottom of the fixed grinding disc 71. Grinding grooves are provided on both sides of the fixed grinding disc 71 and the rotating grinding disc 72 that are close to each other. The bottom end of the acetylene generator body 1 is provided with a discharge pipe 8. Support columns 9 are equidistantly installed at the bottom end of the acetylene generator body 1.

[0032] Refer to Figures 1-3 As shown, in this embodiment, the raw materials are first put into the feeding hopper 6. The design of the feeding hopper 6 enables the raw materials to be concentrated and ready to enter the grinding mechanism 7. After the raw materials enter the acetylene generator body 1, they contact the water or other reactants inside the acetylene generator body 1, and a chemical reaction occurs to generate acetylene gas. The waste materials such as carbide slag generated after the reaction are discharged through the discharge pipe 8 at the bottom end of the acetylene generator body 1. At the same time, the acetylene generator body 1 is stably placed on the ground through four support columns 9 to ensure the stable operation of the entire device.

[0033] Embodiment 2

[0034] Refer to Figures 3-5 As shown, the grinding mechanism 7 further includes: a connecting rod 79, a driven bevel gear 73, a transmission shaft 74, a driving bevel gear 75, a driven sprocket 76, a driving sprocket 77, a feeding hole 78, a V-shaped lever 710 and a cross bar 711. The cross bar 711 is fixedly connected inside the feeding hopper 6. The middle part of the cross bar 71 is rotatably connected with the connecting rod 79. One end of the connecting rod 79 is fixedly connected to the bottom end of the rotating grinding disc 72. The bottom end of the connecting rod 79 is fixedly connected to the driven bevel gear 73. One side of the feeding hopper 6 is rotatably connected with the transmission shaft 74. One end of the transmission shaft 74 is fixedly connected to the driving bevel gear 75. The other end of the transmission shaft 74 is fixedly connected to the driven sprocket 76. The driving bevel gear 75 is meshed with the driven bevel gear 73. The output end of the motor 4 is fixedly connected to the driving sprocket 77. The driving sprocket 77 and the driven sprocket 76 are connected by a chain drive. A feeding hole 78 is provided on one side of the fixed grinding disc 71. The top end of the connecting rod 79 extends out of the fixed grinding disc 71 and is fixedly connected to the V-shaped lever 710. The cross section of the cross bar 711 is triangular. The turning point of the V-shaped lever 710 coincides with the center of the feeding hole 78.

[0035] Refer toFigures 3-5 As shown, in this embodiment, when the motor 4 starts, the output end thereof drives the driving sprocket 77 to rotate. The driving sprocket 77 is connected to the driven sprocket 76 through a chain, thereby driving the transmission shaft 74 to rotate. The driving bevel gear 75 at one end of the transmission shaft 74 meshes with the driven bevel gear 73, thereby driving the connecting rod 79 to rotate. One end of the connecting rod 79 is fixedly connected to the rotating grinding disc 72, so the rotating grinding disc 72 starts to rotate around the fixed grinding disc 71. Since grinding lines are provided on both sides of the fixed grinding disc 71 and the rotating grinding disc 72 that are close to each other, this rotational movement causes relative grinding between the two discs, effectively breaking and grinding the lumps in the raw material, reducing the particle size of the raw material. During the grinding process, the raw material to be ground falls into the conveying pipe 3 through the feeding hole 78. At this time, the motor 4 also drives the auger 5 to rotate in the conveying pipe 3. The rotation of the auger 5 generates a pushing force, continuously and stably conveying the raw material to the feeding pipe 2 of the acetylene generator body 1. The design of the V-shaped lever 710 helps to dial the raw material accumulated above the fixed grinding disc 71 into the grinding area, preventing the raw material from caking or blocking in the feeding hopper 6. At the same time, the equilateral triangle design of the cross bar 711 also helps to reduce the accumulation of raw material at the top, improving the feeding efficiency.
