Throwing machine

Abstract

The invention discloses a material throwing machine, comprising: a body, the body is provided with a feeding port and a material throwing port; a material throwing belt located in the body; wheels; and an air curtain device, which is arranged near the ejection port of the machine body to eject gas towards the direction away from the machine body. According to the throwing machine of the present invention, the high-temperature gas and / or flame of the roasting furnace can reduce the damage to the throwing belt, thereby prolonging the service life, reducing maintenance and replacement, and reducing costs.

Description

technical field [0001] The invention relates to non-ferrous metal pyrometallurgical machinery and equipment, more specifically to a throwing machine. Background technique [0002] Throwing machine is a commonly used equipment in the field of non-ferrous metal pyrometallurgy. The throwing machine is installed next to the feed port of the roasting furnace, so that the materials discharged from the material distributor, such as concentrate powder and other similar fine powder and small granular materials, are thrown into the roasting furnace or other equipment at high speed, so that the roasting furnace or Other equipment is better able to roast the material. [0003] The traditional throwing belt has low running speed, short material flying distance, low production efficiency and small production capacity, and the material flying distance cannot be adjusted, making it difficult to meet production needs. [0004] The weight of the throwing machine is very large, and it is tra...

AI Technical Summary

Problems solved by technology

[0003] The traditional throwing belt has low running speed, short material flying distance, low production efficiency and small production capacity, and the material flying distance cannot be adjusted, making it difficult to meet production needs

[0004] The weight of the throwing machine is very large, and it is traditionally moved by manual push and pull, so it is very laborious

[0005] In addition, the high-temperature gas and / or flame of the traditional throwing machine will enter the throwing machine from the feed port of the roasting furnace through the throwing port, which will damage the throwing tape of the throwing machine, so the life of the tape is low and the replacement is frequent. Increased costs and reduced work efficiency

[0006] The throwing angle of the traditional throwing machine is fixed, and usually cannot be adjusted according to the needs, especially the positive angle throwing cannot be achieved, so the throwing distance and effect are insufficient
