[0002] Dissolved acetylene is a chemical that is widely used in lighting, welding, cutting and various flame processing, and can meet the needs of special users such as scientific research and construction.

[0003] In the production of dissolved acetylene, crude acetylene gas is first produced through the reaction of calcium carbide with water or slaked lime. The crude acetylene gas is then purified and compressed. The acetylene gas is then compressed and filled into a steel cylinder filled with a porous filler solvent, generally acetone solvent, to complete the preparation and production of dissolved acetylene.

[0004] In the process of the reaction of calcium carbide with water or slaked lime, due to the consumption of calcium carbide, new calcium carbide needs to be continuously added to the reaction tank, but the size of calcium carbide itself varies. If it is blindly added to the reaction tank, it is difficult for the larger calcium carbide to fully react in a short time, which leads to a decrease in the reaction rate and affects the production progress of acetylene. To this end, we propose a feeding device for dissolved acetylene production to solve the above problems. Utility Model Content

Therefore, the rotation setting of the cylinder 2 can rotate the cylinder 2 upward first when opening the cover plate to avoid the cylinder 2 hindering the opening of the cover plate;

[0026] Specifically, Figure 2 As shown, the telescopic frame includes a telescopic mechanism 19, the top of the telescopic mechanism 19 is rotatably installed in the first U-shaped seat 21, and the first U-shaped seat 21 is fixedly connected to the cylinder 2, and the bottom of the telescopic mechanism 19 is rotatably installed in the second U-shaped seat 22, and the second U-shaped seat 22 is fixed on the second support plate 20, and the second support plate 20 is fixedly connected to the fixed frame 18.

The wedge block 27 is fixed in the crushing box 6, and the top inclined surface of the wedge block 27 corresponds to the gap between the two crushing rollers 8. At this time, the calcium carbide will fall between the two crushing rollers 8 along the top surface of the wedge block 27, and will be crushed into small pieces through the rotation of the two crushing rollers 8. Subsequently, a guide plate 28 with an inclined setting that concentrates the calcium carbide to the drop port 7 is installed at the bottom of the crushing box 6.
