Description

Technical Field

[0001] The utility model relates to the field of metallurgical grade silicon, in particular to a stepwise dust removal and collection device for metallurgical grade silicon production. Background Art

[0002] The raw materials for smelting metallurgical grade silicon mainly include silica and carbonaceous reducing agents. Due to strict restrictions on the contents of aluminum, calcium, and iron in metallurgical grade silicon, the requirements for raw materials are also particularly strict.

[0003] In different processes, the production of metallurgical grade silicon requires the mixing of multiple materials; a large number of devices are needed for batching or specifically for mixing.

[0004] The above devices have a very high cost and require a large amount of plant space.

[0005] In the process of metallurgical grade silicon production, if it is possible to feed materials without climbing heights and achieve safe and movable feeding, the industry status quo will be changed.

[0006] Moreover, in industrial control, it is necessary to control soot and dust.

[0007] CN217229536U discloses a new type of automatic batching and feeding device for metallurgical grade silicon smelting. The new type of automatic batching and feeding device for metallurgical grade silicon smelting includes a feeding hopper arranged on a smelting furnace body, a crushing box is arranged on one side of the feeding hopper, and a transition box is arranged above the feeding hopper; its structure is too complex, and it has prominent disadvantages, that is, the feeding is all placed above the smelting furnace, and the material requirements are very high. It should be noted that the smelting furnace has a high temperature, and it is difficult to repair and is not safe to place a funnel above it because the high temperature will damage the material and bolts, etc.

[0008] CN220222105U discloses a feeding mechanism for metallurgical grade silicon. It solves the problem that metallurgical grade silicon in the barrel cannot be discharged smoothly. It cannot feed multiple substances simultaneously.

[0009] CN117065839A discloses a new type of automatic batching and feeding device and method for metallurgical grade silicon smelting, including a mixing box, a crushing box, and a feeding mechanism. The upper end of the mixing box is equipped with a feeding hopper, and a mixer is installed in the inner cavity of the mixing box. The crushing box is installed below the mixing box. The structure is too complex. For example, the hopper and the mixing box actually belong to two parts of the scheme, with too high a cost and not easy to move.

[0010] CN216376247U discloses a batching and feeding device for metallurgical grade silicon smelting, which relates to the technical field of metallurgical grade silicon production equipment, including a workbench surface, four support legs, three batching boxes, three feeding pipes, and three discharging pipes, with too high a cost and not easy to move.

[0011] After careful comparison, the defects of these technologies are as follows:

[0012] 1. Insufficient safety, there is no mechanical equipment that can safely lift heavy-quality basic raw materials; 2. It cannot feed multiple substances simultaneously in a comprehensive manner; 3. It is not safe enough; 4. The cost is too high and it is not easy to move.
