Description

Technical Field

[0001] This utility model relates to the technical field of powder mixing equipment, specifically to a stable mixing device for cyanuric chloride and silica. Background Technology

[0002] Cyanide chloride appears as a white powder, is unstable in air, and is volatile and irritating. It has a melting point of 145.5℃, is slightly soluble in water, and easily decomposes into cyanuric acid upon contact with water and alkalis, releasing hydrogen chloride gas. Fumed silica is a white, fluffy powder, porous, non-toxic, odorless, and pollution-free, and resistant to high temperatures. It is used to regulate free flow and as an anti-caking agent to improve powder properties. Cyanide chloride gas enters the crystallizer and, under the action of cold air, directly sublimates into solid cyanide chloride powder. Simultaneously, an automatic silicon feeder adds powdered silica to the crystallizer. The solid cyanide chloride powder and silica are then mixed in a stirring tank. Existing cyanide chloride and silica mixing equipment cannot stably control the silicon content of the cyanide chloride product to the required production process level (2‰-2.5‰), and the uniformity of the silicon content in the cyanide product is poor, with dead zones and stratification occurring.

[0018] In use, a measured amount of cyanuric chloride is fed into the tank 1 through the cyanuric chloride inlet 9, and a measured amount of silica is fed into the tank 1 through the silica inlet 10. The top of the tank 1 is sealed by a top plate 4, and a mixing motor 5 is mounted on top of the top plate 4. The mixing motor 5 drives the main shaft 6 to rotate, which in turn drives the mixing frame 8 to mix and stir the cyanuric chloride powder and silica powder inside the tank 1. Simultaneously, the main shaft 6 drives the conveying screw 7 to rotate inside the tipping pipe 2, further mixing the cyanuric chloride powder and silica powder. Silica powder is fed into the inside of the tipping pipe 2 through the lower slot 3. The relative rotation of the conveying screw 7 and the tipping pipe 2 lifts the cyanuric chloride powder and silica powder to the upper part of the tipping pipe 2. The powder is then output to the upper part of the tank 1 through the upper slot 3. The cyanuric chloride powder and silica powder are mixed again by the mixing frame 8.

The reinforcing frame 11 is provided at the upper end of the top plate 4 to enhance the support capacity of the top plate 4 for the upper equipment. The reducer 12 is provided on the reinforcing frame 11 to reduce the power of the hybrid motor 5 and convert it into the rotation of the main shaft 6. The sealing bushing 13 is provided on the top plate 4 to ensure the sealing between the main shaft 6 and the top plate 4.
