Description

Technical Field

[0001] This application relates to the field of acetylene production technology, and in particular to an acetylene gas production device. Background Technology

[0002] Acetylene, as an important basic organic raw material, occupies an irreplaceable position in the industrial field. Besides its widespread use in fuels, metal welding and cutting, it also plays a crucial role in the production of chemical products such as synthetic rubber, vinylon, acetic acid, and acetaldehyde. With the rapid development of modern industry, the market demand for acetylene gas continues to rise, which places higher demands on the efficiency and quality of acetylene production.

[0003] In the production of acetylene gas, the reaction of electrolytic stone (calcium carbide) with water is the main method of preparation. The pretreatment of the electrolytic stone, especially the crushing process, directly affects the efficiency of subsequent reactions and the quality of the acetylene gas produced. Electrolytic stone typically exists in block form with significant initial volume variations; some large blocks can reach diameters of over one meter. These large blocks of electrolytic stone are hard and have a dense structure, posing a significant challenge to crushing.

[0004] Existing crushing equipment has significant limitations when processing large-diameter electrolytic stones. Most primary crushing equipment has limited feed opening size and insufficient crushing force, making it impossible to effectively crush large electrolytic stones directly. Therefore, in actual production, it is often necessary to manually break up large electrolytic stones using hammers, chisels, and other tools to reduce their particle size to meet the feed requirements of the primary crusher before further fine crushing. This manual pretreatment method is not only extremely labor-intensive and consumes a large amount of manpower, but also has low production efficiency, severely restricting the continuous and large-scale operation of the entire acetylene production line.

[0005] Furthermore, during manual crushing, the particle size of electrolytic stone is difficult to control, easily resulting in uneven particle size. This not only affects the operational stability of subsequent crushing equipment but also leads to inconsistent reaction contact areas between the electrolytic stone and water, resulting in incomplete reactions. This reduces the acetylene gas production rate and may also cause safety hazards due to excessively vigorous local reactions. Simultaneously, manual operation carries a high risk of workplace injury; flying fragments may injure operators, failing to meet modern industrial safety standards.

[0006] With the continuous improvement of industrial automation, traditional crushing methods can no longer meet the needs of efficient, safe and continuous production. Developing equipment that can automatically and efficiently crush large-volume electrolytic stones has become the key to improving acetylene production efficiency, reducing production costs and ensuring production safety. Summary of the Invention

[0007] To address the aforementioned problems, this application provides an acetylene gas production device.

[0008] An acetylene gas production device includes a multi-stage crushing module, a gas catalytic device, and a gas collection tank. The multi-stage crushing module includes a primary crushing device, a screening crushing device, and a secondary crushing device. The outlet of the primary crushing device is connected to the inlet of the screening crushing device via a conveyor belt. The screening crushing device includes a screening shell, a base frame, and a vibration drive mechanism. The screening shell is suspended above the base frame by several shock-absorbing springs. The vibration drive mechanism is fixed to the bottom of the screening shell and its output end abuts against the base frame to drive the screening shell to reciprocate horizontally. The screening shell is spaced vertically. The device is equipped with a coarse screen and a fine screen. The coarse screen is horizontally positioned, and a side outlet is provided on the side of the screening housing facing the secondary crushing device. The side outlet corresponds to the coarse screen and is connected to the inlet of the secondary crushing device via a conveyor belt. A fine crushing roller is provided at the end of the fine screen inside the screening housing. The roller surface of the fine crushing roller is spaced with crushing teeth. The fine screen is inclined toward the fine crushing roller. The fine screen receives the electrolytic stone after screening by the coarse screen and is transported toward the fine crushing roller along the inclined direction by the vibration of the screening housing. The electrolytic stone after being crushed by the fine crushing roller is transported to the gas catalytic device via the main outlet conveyor belt of the screening and crushing device.

[0009] By adopting the above technical solution, multi-stage crushing and grading of electrolytic stone is realized. Large pieces of electrolytic stone do not need to be pre-treated manually. Electrolytic stone of different particle sizes can be automatically separated and crushed in a targeted manner, effectively controlling the particle size of electrolytic stone, improving crushing efficiency and uniformity, and laying the foundation for subsequent reactions.

[0010] Preferably, the device further includes a cleaning device comprising a cleaning tank with an open top, in which horizontal spiral blades are horizontally arranged. The two ends of the rotating shaft of the horizontal spiral blades are rotatably connected to the side wall of the cleaning tank through bearing seats, and one end of the rotating shaft extends out of the cleaning tank and is connected to a drive motor. The cleaning device also includes multiple spray pipes mounted above the cleaning tank. The multiple spray pipes are arranged along the length of the cleaning tank, and spray holes are evenly opened on the pipe body facing the inside of the cleaning tank. The spray pipes circulate and spray inert cleaning liquid into the cleaning tank through a circulating pump. The outlet of the cleaning tank is located below the end of the horizontal spiral blades, and the outlet is connected to the inlet of the primary crushing device through a conveyor belt.

[0011] By adopting the above technical solution, the surface of the electrolytic stone can be cleaned before it enters the crushing stage to remove impurities and dust, thus avoiding the impact of impurities on the operational stability of the crushing equipment and the purity of subsequent reactions. The horizontal spiral blades drive the electrolytic stone to move and achieve continuous cleaning. The inert cleaning fluid is recycled to save resources and improve the pretreatment effect.

[0012] Preferably, the gas catalytic device includes a vertical gas catalytic tank, the top of which has a packing inlet. The feed end of the packing inlet is connected to the main outlet of the screening and crushing device via a conveyor belt. An electrically controlled flap door is installed inside the packing inlet. A spreader is fixedly installed at the packing inlet. The spreader includes a horizontally arranged spreading disc. Several arc-shaped spreading blades are evenly fixed on the spreading disc along the circumference. Electrolytic stones conveyed by the conveyor belt fall to the central area of ​​the spreading disc. The spreading disc rotates and evenly throws the electrolytic stones radially into the gas catalytic tank.

[0013] By adopting the above technical solution, the spreader can evenly spread the electrolytic stone in the gas catalytic tank, avoiding the accumulation of electrolytic stone, increasing its contact area with the reaction medium, making the reaction more uniform and complete, and improving the generation efficiency of acetylene gas.

[0014] Preferably, a vertical spiral blade is vertically arranged inside the gas catalytic tank, and the shaft of the vertical spiral blade passes through the bottom of the gas catalytic tank and is connected to the drive motor for transmission; a pressurized nozzle is fixed at the center of the top of the gas catalytic tank, and the pressurized nozzle is connected to a water source through a pressurized pump, and multiple spray nozzles are evenly distributed around the circumference of the nozzle.

[0015] By adopting the above technical solution, the vertical spiral blades can drive the electrolytic stone to move continuously inside the tank. Combined with the multi-directional uniform water spraying from the pressurized nozzle, this ensures that the electrolytic stone and water are in full contact and react, reducing the possibility of excessively violent local reactions and improving the stability and safety of the reaction process.

[0016] Preferably, the gas catalytic device further includes a purification device fixedly installed outside the gas catalytic tank, and the purification device is connected to the gas catalytic tank through a pipeline.

[0017] By adopting the above technical solution, the purification device can purify the acetylene gas generated by the reaction, remove impurities and moisture, improve the purity of the acetylene gas, and meet the gas quality requirements of industrial production.

[0018] Preferably, the purification device is sealed to a gas collection tank via a pipeline, and the gas collection tank is a sealed steel pressure vessel.

[0019] By adopting the above technical solution, the gas collection tank of the steel sealed pressure vessel can safely store purified acetylene gas, with good pressure resistance and sealing performance, preventing gas leakage, ensuring the safety of the storage process, and avoiding contamination of the gas by external impurities.

[0020] Preferably, the gas catalytic tank has a waste outlet at the center of its bottom, and an electrically controlled gate is installed inside the waste outlet. The electrically controlled gate is linked to the operating cycle of the vertical spiral blades to discharge waste at regular intervals.

[0021] By adopting the above technical solution, the waste generated by the reaction can be automatically discharged at regular intervals, avoiding the accumulation of waste in the tank and affecting the reaction efficiency. The linkage control makes the discharge process match the reaction cycle, ensuring the continuity of production.

[0022] Preferably, it also includes a waste pool for receiving waste, the waste pool being connected to a waste outlet via a conveyor belt.

[0023] By adopting the above technical solutions, the waste pool can centrally collect reaction waste, which is convenient for subsequent unified treatment or recycling. The conveyor belt conveying realizes the automation of waste treatment, reduces manual operation, and reduces labor intensity.

[0024] Preferably, the multi-stage crushing module is covered with a closed dustproof shell, and the dustproof shell is connected to an industrial dust collection device through a metal pipe.

[0025] By adopting the above technical solutions, the dustproof shell and industrial dust collection device can effectively reduce the spread of dust generated during the crushing process, prevent the fine electrolytic stone particles from reacting prematurely with moisture in the air and causing safety hazards, and at the same time improve the working environment and protect the health of operators.

[0026] Preferably, it also includes a sealed housing that covers the cleaning device, the multi-stage crushing module, the gas catalytic device, and the gas collection tank, as well as the area where the conveyor belt connects them.

[0027] By adopting the above technical solutions, the sealed shell forms an overall sealed environment, further preventing acetylene gas leakage and external pollutants from entering the production system, thereby improving the overall safety and stability of equipment operation and ensuring the closed nature of the production process.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. It has achieved full automation of the process of crushing, washing, reacting, purifying and collecting electrolytic stone, replacing the traditional manual pretreatment method, greatly reducing labor intensity, reducing labor costs, significantly improving production efficiency, and meeting the needs of large-scale production; 2. By controlling the uniformity of electrolytic stone particle size through multi-stage crushing and grading screening, combined with uniform spreading and full contact reaction design, the electrolytic stone reacts more fully with water, increasing the acetylene gas production rate, while reducing local violent reactions and lowering safety hazards; 3. Through multiple protections and purification processes, including dustproof shells, sealed shells, and steel pressure vessels, the production process is ensured to be safe, effectively preventing gas leakage and impurity contamination, improving the quality of acetylene gas, and meeting the safety and quality standards of modern industrial production.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] In the description of the invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.

[0033] This application discloses an acetylene gas production device, referring to... Figure 1 , Figure 2 and Figure 3 It mainly consists of a multi-stage crushing module, a gas catalytic device 6, a gas collection tank 7, a cleaning device 11, waste treatment-related components, and sealing and protection components. The various parts are connected by conveyor belts or pipelines to work together to complete the acetylene gas production process. The multi-stage crushing module includes a primary crushing device 21, a screening and crushing device 31, and a secondary crushing device 41. The three are connected by conveyor belts to realize the transfer and processing of electrolytic stones.

[0034] Reference Figure 2 and Figure 3 The cleaning device 11 includes a cleaning tank 113 with an open top. A horizontally arranged helical blade 112 is mounted inside the tank, with its rotating shaft rotatably connected to the side wall of the cleaning tank 113 via bearing seats at both ends. One end of the shaft extends out of the cleaning tank 113 and is connected to a drive motor. Multiple spray pipes 111 are mounted above the cleaning tank 113, arranged along its length. The spray pipes 111 have evenly spaced spray holes facing inwards towards the cleaning tank 113 and form a circuit with the cleaning tank 113 via a circulating pump, allowing for the circulating spraying of inert cleaning fluid into the tank. The outlet of the cleaning tank 113 is located below the end of the horizontal helical blade 112 and is connected to the inlet of the primary crushing device 21 via a conveyor belt. During operation, raw electrolytic stones enter the cleaning tank 113, and the drive motor rotates the horizontal helical blade 112, propelling the electrolytic stones along the length of the cleaning tank 113 towards the outlet. Simultaneously, a circulating pump delivers inert cleaning fluid to spray pipe 111, which is then sprayed onto the moving electrolytic stone surface through spray holes for cleaning. The cleaned electrolytic stone is then conveyed to the primary crushing unit 21 via a conveyor belt from the outlet of cleaning tank 113.

[0035] Reference Figure 3 and Figure 4 The outlet of the primary crushing device 21 is connected to the inlet of the screening and crushing device 31 via a conveyor belt. This connection is used to initially crush the incoming electrolytic stone, breaking it down into smaller pieces with a diameter of 50-100 mm. The pre-crushed electrolytic stone is then conveyed to the screening and crushing device 31 for sieving. The screening housing 314 of the screening and crushing device 31 is suspended above the base frame 317 by several damping springs 318. These springs are connected to the bottom of the screening housing 314 and the top of the base frame 317, providing cushioning for vibrations. The vibration drive mechanism is fixed to the bottom of the screening housing 314, with its output end abutting against the base frame 317. Upon startup, it drives the screening housing 314 to reciprocate horizontally.

[0036] Reference Figure 3 and Figure 4The screening housing 314 contains a coarse screen 311 and a fine screen 312 fixed at intervals. The coarse screen 311 is horizontally positioned, corresponding to the side outlet 315 on the side of the screening housing 314 facing the secondary crushing device 41. The side outlet 315 is connected to the inlet of the secondary crushing device 41 via a conveyor belt. The fine screen 312 is inclined towards the fine crushing roller 313, and the roller surface of the fine crushing roller 313 is spaced with crushing teeth. The end of the fine screen 312 extends to the fine crushing roller 313. During operation, the electrolytic stones after primary crushing enter the screening housing 314 and fall onto the coarse screen 311. Under the horizontal reciprocating vibration of the screening housing 314, the coarse screen 311 filters out electrolytic stones with a diameter greater than 100 mm. Electrolytic stones with a diameter greater than 100 mm move towards the side outlet 315 on the coarse screen 311 and enter the secondary crushing device 41 via the conveyor belt through the side outlet 315. Electrolytic stones meeting the required particle size (diameter less than or equal to 100 mm) pass through the coarse screen 311 and fall into the fine screen 312 below. Under the vibration of the screening housing 314 and its own tilt angle, the electrolytic stones on the fine screen 312 move along the inclined direction towards the fine crushing roller 313. Upon reaching the fine crushing roller 313, they are crushed by the crushing teeth on the roller, producing electrolytic stone particles with a diameter of 1-3 mm. These particles are then discharged through the main outlet of the screening and crushing device 31 and enter subsequent processing stages. The secondary crushing device 41 receives the electrolytic stones conveyed from the side outlet 315 of the screening and crushing device 31, further crushes them to a diameter of less than 50-100 mm, and then re-conveys them to the screening and crushing device 31 for screening, forming a cyclic crushing process until the electrolytic stone particle size meets the screening requirements of the coarse screen 311.

[0037] Reference Figure 5 and Figure 6 The vertical gas catalytic tank 61 of the gas catalytic device 6 has a packing inlet 611 at its top. Its feed end is connected to the main outlet of the screening and crushing device 31 via a conveyor belt. An electrically controlled flap door is installed inside the packing inlet 611 to control the entry of electrolytic stones. A spreader fixed at the packing inlet 611 includes a horizontally arranged spreading disc 63, on which several arc-shaped spreading blades 64 are evenly fixed circumferentially. Electrolytic stones discharged from the main outlet of the screening and crushing device 31 are conveyed to the packing inlet 611 via a conveyor belt. After the electrically controlled flap door opens, the electrolytic stones fall to the central area of ​​the spreading disc 63, which rotates to evenly throw the electrolytic stones radially into the gas catalytic tank 61.

[0038] Reference Figure 7The gas catalytic converter 61 contains vertically mounted vertical spiral blades 612, whose shafts pass through the bottom of the converter and are connected to a drive motor. Upon startup, the spiral blades 612 rotate within the converter. A pressurized nozzle 613 is fixed at the center of the top of the gas catalytic converter 61, connected to a water source via a pressurized pump. Multiple nozzles are evenly distributed around the circumference of the nozzle, spraying water into the converter. When electrolytic stones are thrown into the gas catalytic converter 61, the spiral blades 612 rotate, propelling the electrolytic stones within the converter. Simultaneously, the pressurized nozzle 613 sprays water into the converter through the nozzles, causing the electrolytic stones to react with the water to generate acetylene gas. A waste outlet 614 is located at the center of the bottom of the gas catalytic converter 61, containing an electrically controlled gate. This gate is linked to the operating cycle of the spiral blades 612 and can be opened periodically to discharge the waste generated during the reaction. Waste outlet 614 is connected to waste pool 8 via a conveyor belt, and the discharged waste is transported to waste pool 8 for collection via the conveyor belt.

[0039] Reference Figure 5 A purification device 62 is fixed to the outside of the gas catalytic tank 61 and connected to the gas catalytic tank 61 through a pipeline. It can purify the acetylene gas generated in the reaction. The purification device 62 is sealed to the gas collection tank 7 through a pipeline. The purified acetylene gas enters the gas collection tank 7 for storage. The gas collection tank 7 is a sealed steel pressure vessel.

[0040] Reference Figure 2 During the crushing process, small-diameter electrolytic stone particles are easily generated. These small particles readily disperse in the air and mix with moisture to prematurely produce acetylene gas. To prevent this, the multi-stage crushing module is enclosed in a sealed dustproof shell 100. The dustproof shell 100 is connected to an industrial dust collection device 5 via metal pipes, which reduces the diffusion of dust generated during crushing. Simultaneously, the equipment also includes a sealed shell covering the cleaning device 11, the multi-stage crushing module, the gas catalytic device 6, the gas collection tank 7, and the conveyor belt connection areas between them, forming a completely sealed environment to ensure production safety.

[0041] The implementation principle of this embodiment is as follows: After being cleaned by the cleaning device 11, the raw electrolytic stone enters the multi-stage crushing module for step-by-step crushing and screening to obtain electrolytic stone that meets the particle size requirements. The electrolytic stone then enters the gas catalytic device 6, where it reacts with water to generate acetylene gas. After purification by the purification device 62, the gas is stored in the gas collection tank 7. Waste generated during the reaction is periodically discharged to the waste pool 8. The entire process is carried out under the protection of the dustproof shell 100 and the sealed shell, achieving efficient and safe production of acetylene gas.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
