Problems solved by technology

[0005] The object of the present invention is to provide drying equipment for metal silicon microwave smelting, which solves the problem that during the feeding process, the product block will continuously hit the nozzle, which will not only damage the connection between the nozzle and the tank wall, but even cause the nozzle to be temporarily damaged by the product block. Coverage is not conducive to the smooth progress of metal silicon smelting

Embodiment 1

[0035] like Figure 1-Figure 8 As shown, the drying equipment for metal silicon microwave smelting of the present invention includes a drying tank 1 and a nozzle assembly connected in sequence, an air supply system and a nozzle 5. The nozzle 5 is located in the inner cavity of the drying tank 1, and the nozzle 5 is connected to the drying tank 1. The feed inlet 3 is opposite, and an anti-collision assembly is sleeved on the side wall of the nozzle 5 close to the nozzle. 10. One end of the connection cylinder 7 is sleeved on the nozzle 5, and the other end of the connection cylinder 7 is connected to the support plate 9 through a spring 8. The telescopic direction of the spring 8 is parallel to the axis of the nozzle 5. The support plate 9 Vertical to the axis of the nozzle 5, and the support plate 9 is provided with a ventilation hole 11 whose axis coincides with the axis of the nozzle 5. The support assembly includes two vertical plates 12 parallel to each other, and the bott...

Embodiment 2

[0038] Spring 8 is a helical cylinder compression spring.

Embodiment 3

[0040] This embodiment is based on Embodiment 1 to describe the air guiding system.

[0041] like Figure 1-Figure 8 As shown, in the drying equipment for metal silicon microwave smelting of the present invention, an air guide system is arranged between the air supply system and the nozzle 5, and the air guide system includes a hollow air guide ring 4 and an air guide pipe 2. In the drying tank 1 A support ring 15 is provided on the inner wall of the support ring 15, the axis of the support ring 15 coincides with the axis of the drying tank 1, the outer wall of the support ring 15 is connected with the inner wall of the drying tank 1, and the outer wall of the air guiding ring 4 is connected with the drying tank 1. The inner wall is in contact, the bottom of the air guide ring 4 is in contact with the top of the support ring 15, and the center line of the air guide ring 4 coincides with the center line of the drying tank 1, and several support cylinders 6 are arranged on the t...

Abstract

The invention discloses drying equipment for metallic silicon microwave metallurgy. The equipment comprises a drying tank, nozzle assemblies, air supply systems and nozzles; the nozzles are sleeved with anti-collision components which comprise connecting cylinders, springs, support plates, support assemblies and slag separation nets, one ends of the connecting cylinders sleeve the nozzles, the other ends of the connecting cylinders are connected with the support plates through springs, air holes are formed in the support plates, each support assembly comprises two vertical plates, the bottomsof the vertical plates are connected with the upper surfaces of the support pates, the slag separation nets and the air holes are located between the support plates, the two ends of each slag separation net are connected with the two vertical plates respectively, the ends, away from the support plates, of the slag separation nets make contact with each other, and the other ends of the slag separation nets are away from each other. When product blocks hit the slag separation nets, the springs are compressed, and then impact of the product blocks to the slag separation nets is relieved; therefore, stress borne by the joint parts between the connecting cylinders and the nozzles is lowered, the service life of the equipment is prolonged, and noise in the drying process is lowered.

Description

technical field [0001] The invention relates to the field of materials, in particular to drying equipment for metal silicon microwave smelting. Background technique [0002] Silicon metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Silicon metal is a product smelted from quartz and coke in an electric furnace. The main component silicon content is about 98%, and the remaining impurities are iron, aluminum, calcium, etc. Silicon is one of the semi-metals, formerly known as "silicon". The melting point is 1420°C and the density is 2.34 grams per cubic centimeter. Hard and brittle. Insoluble in acid at room temperature, easily soluble in alkali. The properties of metallic silicon are similar to those of germanium, lead, and tin, and have semiconductor properties. Silicon is extremely rich in resources in the earth's crust, second only to oxygen, accounting for more than a quarter of the total weight of the...
