The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] like Figure 1-4As shown, the utility model provides a raw material feeding mechanism for crude magnesium smelting, including a reduction tank 100, a hopper 200 and a feeding assembly 300, the reduction tanks 100 are arranged in a row, and the hopper 200 can slide to the filling port of the reduction tank 100 through a track 210, and the track 210 is arranged in parallel just in front of the filling port of the reduction tank 100, so that it can be translated to the position of any reduction tank 100 to realize the transportation of materials. The feeding assembly 300 includes a feeding trough 310, a pusher 320 and an electric trolley 330. The feeding trough 310 extends into the reduction tank 100, so that one end of the feeding trough 310 can be supported at the filling port of the reduction tank 100, and the hopper 200 is located above the feeding trough 310, so that the raw materials dropped from the discharge port of the hopper 200 just fall into the feeding trough 310. The pusher 320 needs to be detachably installed on the electric trolley 330, and the electric trolley 330 can push the pusher 320 to send the raw materials in the feeding trough 310 to the reduction tank 100. When the electric switch of the electric trolley 330 is controlled to move forward, the pusher 320 is pushed forward in a straight line. 20, so that the pusher 320 can directly push the raw materials on the feeding trough 310 into the reduction tank 100. When the electric trolley 330 is controlled to move backward, the electric trolley 330 is pressed downward so that the electric trolley 330 drives the pusher 320 to tilt slightly, so that the pushing end of the pusher 320 can move backward and open the sealing switch 230 of the hopper 200. When a certain amount of raw materials is dropped, the pusher 320 is restored so that it no longer tilts, and the sealing switch 230 is automatically closed under the influence of its own weight, and the actions of controlling the electric trolley 330 to move forward and backward are repeated in sequence to realize repeated feeding process.

[0031] On the basis of the above technical solution, it should be noted that the present invention is specifically configured as follows.

[0032] like Figure 1-Figure 4 As shown, the hopper 200 is symmetrically provided with a clamp 220 that slides along the length direction of the track 210. The clamp 220 can be set as a block structure or a pulley structure, which can ensure that the clamp 220 can not only lift the hopper 200, but also can easily slide the hopper 200 loaded with raw materials on the track 210, and the movement mode of the hopper 200 on the track 210 can be either manual push or electric control.

[0033] A sealing switch 230 is provided at the discharge port at the bottom end of the hopper 200. When the pushing end of the pusher 320 is raised, the sealing switch 230 can be opened. The sealing switch 230 is an arc structure with one end being heavy and the other end being light. The heavy end is hinged to the hopper 200. The discharge port of the hopper 200 can only be opened by driving the light end of the sealing switch 230 with external force. The pusher 320 does not contact the light end of the sealing switch 230, and the sealing switch 230 is in a locked state.

[0034] The pushing end of the pusher 320 is a semi-arc structure, and the feeding trough 310 has an arc-shaped cavity 311 that is compatible with the pusher 320. The pushing end of the pusher 320 can move smoothly in the arc-shaped cavity 311. At the same time, the setting of this arc-shaped structure can better push the raw materials in the arc-shaped cavity 311 directly and fully into the reduction tank 100, which is more convenient and practical than other structural shapes.

[0035] The pushing end of the pusher 320 has a protrusion 321 that can open the sealing switch 230. The upward height of the protrusion 321 cannot be higher than the height from the pusher 320 to the sealing switch 230, and the protrusion 321 only plays a role in driving the lighter end of the sealing switch 230 to open after the pusher 320 is tilted, so that the raw material falls directly onto the feeding trough 310.

[0036] One end of the feeding trough 310 can be supported on the mouth of the reduction tank 100, and the other end has a detachable supporting leg 312. The upper end of the supporting leg 312 is consistent with the contact surface of the feeding trough 310, and needs to have a certain contact area, so that stable and rapid supporting operations can be performed. At the same time, the height of the supporting leg 312 is basically flush with the bottom end of the inner diameter of the reduction tank 100, so that the stability of the feeding trough 310 can be achieved.

[0037] An opening 313 for the pusher 320 to move is provided at one end of the feeding trough 310 away from the reduction tank 100, and a roller 3131 is provided at the opening 313. The opening 313 can limit the movement direction of the pusher 320 to a certain extent, and the setting of the roller 3131 can enable the pusher 320 to move smoothly back and forth.

[0038] The electric trolley 330 has a lock 331 for positioning the pusher 320. The pusher 320 is a steel bar with an arc-shaped structure at the front end. When fixing the pusher 320, the steel bar portion is passed through the lock 331, and then the bolt on the lock 331 is screwed so that the bolt end entering the lock 331 presses the steel bar portion into position, thereby realizing rapid disassembly and assembly of the lock 331 and the pusher 320.

[0039] The specific working principle and use method of the utility model are as follows:

[0040] The utility model provides a raw material feeding mechanism for crude magnesium smelting. When in use, the raw materials required for smelting crude magnesium are loaded into the hopper 200, and then the hopper 200 is pushed to slide on the track 210, and the hopper 200 is transported to the front of the reduction tank 100, and then one end of the feeding trough 310 is supported at the mouth of the reduction tank 100, and then the other end is balanced and supported by the support leg 312. At this time, the feeding port of the hopper 200 is just above the arc cavity 311 of the feeding trough 310, and then the worker controls the direction of the electric trolley 330 to move forward. It is enough to drive the pusher 320 to drop the hopper 200 to the raw materials in the arc-shaped cavity 311 and directly push them into the reduction tank 100. When the electric trolley 330 moves backward, it is necessary to press the electric trolley 330 downward to drive the pusher 320 to tilt, so that the protrusion 321 on the pushing end can open the sealing switch 230. At this time, the raw materials fall, and then the electric trolley 330 is flattened. The sealing switch 230 will be automatically closed due to its own weight, and then the electric trolley 330 is controlled to repeat the actions of pushing the materials forward in parallel and pulling them backward in an inclined manner.

[0041] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
