Description

Technical Field

[0001] The invention belongs to the technical field of glass manufacturing, and in particular relates to an environmentally friendly precise feeding and cooling system in a float glass production process. Background Art

[0002] Feeder is a commonly used mechanical equipment in the glass production process. As a feeding device for glass manufacturers, feeder is a function to achieve continuous feeding to meet the needs of glass production. Since the melting of glass requires the proportion of multiple raw materials, by accurately controlling the components of each raw material, glass with different properties can be obtained. Therefore, in the glass melting production, accurate batching and feeding is a crucial step.

[0003] At present, there are the following problems in the feeding process:

[0004] 1. In the early stage of feeding, the raw materials should be stored for a short time and kept dry during storage, otherwise agglomeration will occur;

[0005] 2. The stored raw materials will generate dust during transportation, which will affect the health of the workers and bring potential safety hazards;

[0006] 3. The unevenness caused by the agglomeration of raw materials will lead to inaccurate weighing;

[0007] 4. The proportions of various raw materials are not accurate and require manual assistance, which increases labor costs;

[0008] 5. A certain amount of glass waste will be generated during the production process, which needs to be recycled;

[0009] 6. The temperature of the connection part between the feeding equipment and the melting furnace is too high. Under the action of high temperature and flame, it often deforms and sags, scratches the pool wall and causes production accidents;

[0010] 7. The burned and deformed lip plate is a spliced ​​connection part, and the bottom support plate is a welded original part, which makes replacement difficult and affects production, causing great losses to the manufacturer.

[0011] In response to the above problems, it is necessary to improve the degree of automation on the basis of existing technology, avoid dust pollution, and solve the problem of melting furnace damaging feeding equipment. Summary of the invention
