Technical Field

[0001] This application relates to the field of acetylene gas preparation, and particularly to a crushing device for feeding acetylene raw materials. Background Art

[0002] Acetylene, commonly known as wind coal and calcium carbide gas, is the simplest alkyne compound. It is a colorless and extremely flammable gas at room temperature and is mainly used for lighting, welding, rubber synthesis, etc. The raw material for preparing acetylene is calcium carbide, which is commonly known as carbide. When calcium carbide reacts with water, acetylene is generated.

[0003] A Chinese patent with the publication number CN210458067U discloses an acetylene generator that can automatically feed materials, including a reaction cylinder. The reaction cylinder is provided with a cavity communicating with the outside world, and a water inlet pipe is also provided on the cylinder body near the top of the reaction cylinder; a feeding device is also provided on the reaction cylinder. The feeding device includes a feeding hopper, and the end of the feeding hopper is tightly welded with a feeding pipe. A micro motor is provided on the fixing plate, and the end of the output shaft of the micro motor passes through the feeding pipe and is tightly welded with a feeding blade. A residual liquid collecting cylinder is also tightly welded on the surface of the cylinder body near the bottom of the reaction cylinder, and a cooling mechanism is also provided on the reaction cylinder. It saves time and effort, is simple and fast to operate, makes the raw material reaction in the acetylene generator more smooth, and brings convenience to users.

[0004] However, in actual operation, the raw material calcium carbide fed into the reaction cylinder is directly put into the cavity through the feeding hopper for reaction. Before the raw material calcium carbide is fed into the cavity, there may be large pieces of calcium carbide. If it is directly fed into the cavity for the acetylene generation reaction, there may be problems such as incomplete reaction and long reaction time. Summary of the Utility Model

[0005] In order to alleviate the problems of incomplete reaction and long reaction time when large pieces of calcium carbide are directly fed into the cavity for the acetylene generation reaction, this application provides a crushing device for feeding acetylene raw materials.

[0006] The crushing device for feeding acetylene raw materials provided by this application adopts the following technical solutions:

[0007] A crushing device for feeding acetylene raw materials includes a processing box. The top of the processing box is provided with a feeding port. Guide plates are hinged on the opposite side walls of the feeding port through torsion springs. A plurality of crushing rollers are rotatably connected in the processing box, and crushing teeth are provided on the plurality of crushing rollers. A conveying member is provided at the bottom of the processing box.

[0008] By adopting the above technical solution, during use, large pieces of calcium carbide are placed on the material guiding plate. Under the action of gravity, the material guiding plate rotates, thereby opening the feeding port, and the calcium carbide enters the treatment box. The calcium carbide is crushed by multiple crushing rollers, thereby reducing the possibility of large pieces of calcium carbide reacting, and alleviating the problems of incomplete reaction and long reaction time when large pieces of calcium carbide are directly fed into the cavity for the acetylene generation reaction.

The crushing rod is located inside the treatment box, and multiple crushing protrusions are provided on the crushing rod.

[0014] By adopting the above technical solution, during use, the first motor is started. The rotation of the first motor drives the bidirectional threaded rod to rotate, which can realize the movement of the installation plate, thereby playing a role in adjusting the distance between the two crushing rods. The second motor drives the crushing rod to perform primary crushing, reducing the possibility of too large calcium carbide jumping on the crushing rollers.

[0015] Optionally, a stabilizing block is rotatably arranged at one end of the crushing rod away from the mounting plate. A stabilizing groove is formed in the side wall of the treatment box.

The return spring is sleeved outside the power rod. One end of the return spring is connected to the treatment box, and the other end is connected to the circular plate.

[0022] By adopting the above technical solution, during use, the power rod is pulled, the power rod drives the brush on the cleaning plate to move up, and after releasing, it quickly moves down under the action of the return spring. Repeating the above actions can play a role in removing dust.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. In the present application, through the treatment box, the feeding guide plate, the crushing rollers and the conveying member, the feeding guide plate rotates under the action of gravity, so that the feeding port is opened, and the calcium carbide enters the treatment box.
