Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a crushing device for calcium carbide, which is a raw material for the production of dissolved acetylene and can be quickly ventilated. Background Art

[0002] The main component of calcium carbide is calcium carbide, also known as acetylene calcium, with the chemical formula CaC2. Calcium carbide is a powder or lumpy solid in green or grayish black, with a garlic smell. Industrially, calcium carbide is commonly used to mix with water to produce acetylene gas, and it is also applied in the smelting industry as a reducing agent and desulfurizing agent.

[0003] Before the use of calcium carbide, it needs to be crushed because the block sizes of calcium carbide are different, and a crushing device is required to crush calcium carbide. However, in the existing crushing devices, calcium carbide is directly poured into the crushing device for processing. During the crushing process, due to the lack of protection at the feeding port, splashing is likely to occur, causing harm to the staff. Moreover, during the crushing process, a large amount of dust is easily generated, seriously polluting the working environment. After being inhaled by the staff, it affects the health of the staff, resulting in poor performance during use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a crushing device for calcium carbide, which is a raw material for the production of dissolved acetylene and can be quickly ventilated. After the feeding through the feeding hopper is completed, with the use of the cover plate, the feeding hopper is protected to prevent splashing. At the same time, during the crushing process, under the action of the exhaust fan, the dust generated by crushing passes through the collection pipe and is transported to the dust collection box. With the filtering and blocking of the filter screen, all of it is collected in the dust collection box, preventing the dust from spreading in the working environment and polluting the working environment, which affects the health of the staff.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A crushing device for calcium carbide, which is a raw material for the production of dissolved acetylene and can be quickly ventilated, includes a crushing box. Two symmetrically arranged crushing rollers are rotatably connected inside the crushing box. The upper end surface of the crushing box is fixedly connected with a feeding hopper. A cover plate is hinged on the feeding hopper. A ventilation plate is fixedly connected to the cover plate. One side of the crushing box is fixedly connected with a collection pipe. The side of the collection pipe away from the crushing box is fixedly connected with a dust collection box. A dust collection box is movably connected to one side of the dust collection box. A pulling knob is fixedly connected to one side of the dust collection box. The upper end surface of the dust collection box is fixedly connected with an exhaust pipe.

[0006] The beneficial effects of the present utility model are as follows: By using the feeding hopper, calcium carbide to be crushed is conveyed, and in cooperation with the use of two crushing rollers, the calcium carbide is crushed. During the crushing process, the cover plate can block the feeding hopper to prevent the calcium carbide from splashing during crushing. At the same time, under the action of the exhaust fan, the dust generated during the crushing process is collected and all collected in the dust collection box, which is convenient for unified collection and treatment in the later stage;

[0007] In order to block the feeding hopper to prevent splashing and collect and process the dust generated by crushing;

[0008] As a further improvement of the above technical solution: Two symmetrically arranged positioning plates are fixedly connected to the other side of the crushing box. The upper end surfaces of the positioning plates are fixedly connected with driving motors. The output ends of the driving motors are connected with rotating rods. The rotating rods are rotatably connected to the crushing box and fixedly connected to the crushing rollers.

[0009] The beneficial effects of this improvement are as follows: By the simultaneous reverse rotation of the two driving motors, the respective corresponding rotating rods can be driven to rotate, so that the two rotating rods drive the respective corresponding crushing rollers to rotate towards the center at the same time, and the falling calcium carbide is quickly crushed;

[0010] In order to drive the crushing rollers and ensure the normal operation of the crushing rollers;

[0011] As a further improvement of the above technical solution: An inclined screen is fixedly connected inside the crushing box. The inclined screen is located below the crushing rollers. An outlet is opened on one side of the crushing box away from the collecting pipe.

[0012] The beneficial effects of this improvement are as follows: By using the inclined screen, the crushed calcium carbide can be screened, and the larger calcium carbide particles can be sorted out, which is convenient for differentiated use and prevents the larger calcium carbide from being mixed with the smaller calcium carbide particles, affecting normal use;

[0013] In order to screen the calcium carbide particles;

[0014] As a further improvement of the above technical solution: A connecting cover is fixedly connected to the lower end surface of the crushing box. A collecting box is fixedly connected to the lower end surface of the connecting cover. A collecting box is movably connected to one side of the collecting box. A handle is fixedly connected to one side of the collecting box.

[0016] In order to centrally collect the crushed electric particles;

[0017] As a further improvement of the above technical solution: a ventilation mesh plate is fixedly connected to the inside of one side of the crushing box.

[0018] The beneficial effect of this improvement is that by using the ventilation mesh plate, the crushed calcium carbide in the crushing box can be blocked, while not affecting the normal collection and treatment of dust by the collection pipe;

[0019] To achieve effective ventilation and facilitate dust collection;

[0020] As a further improvement of the above technical solution: two symmetrically arranged guide plates are fixedly connected inside the crushing box, and the guide plates are located above the crushing rollers.

[0021] The beneficial effect of this improvement is that by using the guide plates, the falling calcium carbide can be fully conveyed to the middle of the two crushing rollers, facilitating the comprehensive crushing treatment of calcium carbide by the two crushing rollers, and preventing calcium carbide from falling from both sides and being unable to be effectively crushed;

[0022] To achieve the guiding and conveying of calcium carbide;

[0023] As a further improvement of the above technical solution: a fixing frame is fixedly connected to the outer wall of the crushing box, and the fixing frame is fixedly connected to the collection box and the dust collection box.

[0024] The beneficial effect of this improvement is that by using the fixing frame, the crushing box can be fixed to ensure its stability, and at the same time, the collection box and the dust collection box can be fixed to ensure the stability during use;

[0025] To achieve the fixation of the crushing box, the collection box and the dust collection box. BRIEF DESCRIPTION OF THE DRAWINGS
