[0024] 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.
[0025] This utility model provides, for example Figure 1-4 The solid acetylene generator shown includes an acetylene generator 1 and a feeding hopper 3 installed at the right end of the acetylene generator 1.
[0026] An exhaust pipe 4 is fixedly connected to the upper inner wall of the acetylene generator 1 to guide the generated acetylene gas outward.
[0027] An overflow pipe 7 is fixedly connected to the outer wall of the left end of the acetylene generator 1 to guide the excessive liquid to be discharged.
[0028] An inlet pipe 10 is installed on the outer wall of the right end of the acetylene generator 1. The operator adds solid raw materials, such as calcium carbide or other metal hydrides, into the acetylene generator 1 through the feeding hopper 3 and adds an appropriate amount of water through the inlet pipe 10 so that the reaction materials react with the water. Inside the acetylene generator 1, the solid raw materials react with the water to generate acetylene gas and by-products. The generated acetylene gas is guided to the outside through the exhaust pipe 4 for further use or treatment. If too much liquid accumulates inside due to the reaction, causing the liquid level to be too high, the overflow pipe 7 will function to automatically guide the excess liquid out.
[0029] A filter screen 12 is fixedly connected to the inner wall of the left end of the acetylene generator 1. A filter cylinder 11 is installed inside the overflow pipe 7. A float ball 13 is installed inside the filter screen 12. When the overflow pipe 7 guides the overflowing liquid outward, large pieces can be intercepted by the filter screen 12. Then, under the influence of the liquid level, the float ball 13 floats up and blocks part of the inlet of the overflow pipe 7. The liquid that then enters the overflow pipe 7 can also be filtered a second time by the filter cylinder 11, reducing the possibility of blockage in the overflow pipe 7.
[0030] like Figure 3 and Figure 4 As shown, the outer circular wall of the float 13 is provided with multiple arc-shaped blocks 14 at equal intervals. The outer circular wall of the filter cylinder 11 is fixedly connected to a threaded ring 15 near the right side to engage with the overflow pipe 7. The inner circular wall of the overflow pipe 7 is provided with threads for the threaded ring 15 to engage. Both the filter screen 12 and the filter cylinder 11 are cylindrical.
[0031] As the float 13 moves up and down, the arc-shaped block 14 can push out the impurities stuck in the mesh of the filter screen 12 and remove them, ensuring that the interception performance of the filter screen 12 is not damaged. When the overflow tube 7 is removed, the filter tube 11 can be removed from the overflow tube 7 by rotating the filter tube 11. After cleaning, the filter tube 11 is reinserted into the overflow tube 7, and the threaded ring 15 is screwed into the inner wall of the overflow tube 7 to complete the fixing of the filter tube 11.
[0032] like Figure 3 and Figure 4 As shown, the diameter of the filter cartridge 11 is smaller than the diameter of the overflow pipe 7, and the multiple arc-shaped blocks 14 and the circular inner wall of the filter screen 12 abut against each other.
[0033] The filter cartridge 11 is smaller than the diameter of the overflow pipe 7. When the filter cartridge 11 filters and intercepts impurities, the liquid can continue to flow outward through the gap between the filter cartridge 11 and the inner wall of the overflow pipe 7, thus avoiding the complete blockage of the overflow pipe 7.
[0034] like Figure 1 and Figure 2 As shown, a vibrating feeder 2 is fixedly connected to the inner wall of the right end of the acetylene generator 1 to control the discharge volume. An exhaust pump 5 is fixedly connected to the outer wall of the upper end of the acetylene generator 1 to guide the gas from the exhaust pipe 4 to be discharged outward. A fixed end 6 is fixedly connected between the overflow pipe 7 and the acetylene generator 1 to limit the position of the overflow pipe 7.
[0035] The vibrating feeder 2 uses a motor or other power source to generate vibration, which allows solid raw materials to be discharged more smoothly under the action of gravity. This ensures that the raw materials are continuously and stably fed into the acetylene generator 1, thereby maintaining the continuity of the reaction. By adjusting the vibration frequency and amplitude, the discharge speed and amount can be precisely controlled to ensure the balance of the raw material supply required inside the generator. The exhaust pump 5 works by periodically extracting gas from the generator, so that the generated acetylene gas can flow continuously and be discharged to the outside, preventing safety hazards caused by excessive pressure inside the generator.
[0036] like Figure 1 and Figure 2 As shown, a U-shaped tube 9 is fixedly connected to the lower circular outer wall of the overflow pipe 7, and a drain pipe 8 is provided at the other end of the U-shaped tube 9. A pressure gauge and a temperature gauge are provided on the front outer wall of the acetylene generator 1.
[0037] When the liquid level inside the acetylene generator 1 is too high, the overflow pipe 7 guides the excess liquid to the U-shaped pipe 9 to prevent the liquid level inside the generator from rising to a level that endangers safety. The design of the U-shaped pipe 9 helps to prevent the mixing of gas and liquid. The liquid level is usually balanced by the height difference of the liquid and gravity. When the liquid level in the U-shaped pipe is higher than a certain threshold, the liquid will flow out through the drain pipe 8 to ensure that the system is kept within the normal liquid limit and to avoid liquid backflow or leakage. The pressure gauge usually displays the current gas pressure by measuring the change in gas pressure. The operator can adjust the water inlet, raw material, or exhaust volume in a timely manner according to the pressure gauge reading to ensure the safety and efficiency of the system.
[0038] The implementation principle of this embodiment is as follows: The operator adds solid raw materials, such as calcium carbide or other metal hydrides, into the acetylene generator 1 through the feeding hopper 3, and adds an appropriate amount of water through the water inlet pipe 10 so that the reaction materials react with the water. Inside the acetylene generator 1, the solid raw materials react with the water to generate acetylene gas and byproducts. The generated acetylene gas is guided to the outside through the exhaust pipe 4 for further use or treatment. If too much liquid accumulates inside due to the reaction, resulting in an excessively high liquid level, the overflow pipe 7 will function to automatically guide the excess liquid out. When the overflow pipe 7 guides the overflowing liquid outward, large pieces can be intercepted by the filter screen 12. Subsequently, under the influence of the liquid level, the float ball 13 floats upward, blocking part of the water inlet of the overflow pipe 7. The liquid that then enters the overflow pipe 7 can also be filtered a second time through the filter cartridge 11 to reduce the clogging of the overflow pipe 7.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
