Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to an automatic feeding device for a glass kiln. Background Art

[0002] Glass kiln is a key equipment in the glass manufacturing process. The main structure of glass kiln includes furnace body, heat insulation layer, burner, spray device, etc. The furnace body is made of high temperature resistant materials such as refractory bricks and metal structure to contain the molten material; the heat insulation layer is composed of refractory bricks, fused asbestos, ceramic fiber, etc., which is used to isolate the high temperature zone and the low temperature zone; the burner is responsible for burning fuel and oxygen in the combustion zone to generate high temperature; the spray device is used to spray coolant into the molten pool to adjust the temperature and control the depth of the molten pool.

[0003] The working principle of the glass kiln involves the combustion of fuel, melting, forming and cooling of glass. First, the fuel (such as heavy oil, natural gas, coal gas) reacts with the oxidant (air or oxygen) in the combustion zone to generate high temperature, so that the temperature in the kiln reaches about 1500℃, which is enough to melt the glass raw materials; during the melting process, the raw materials form uniform glass materials at high temperatures; the molten glass liquid flows out of the kiln and is blown and formed into a glass bottle liner; the formed glass is quenched and further processed into the required thermos bottle liner.

[0004] In the production process of glass bottle, the requirements for the control accuracy of raw material feeding are getting higher and higher. Feeding control includes feeding device, feeding method, etc. Feeding control directly affects the quality of glass melting. High feeding accuracy can ensure the stability of the liquid level in the kiln, uniform distribution of material mountain, easy control of hot spot temperature and other conditions that are conducive to improving glass quality. In addition, the thickness of the batch material layer added to the kiln greatly affects the melting speed of the batch material and the production capacity of the kiln. When the batch material is fed in a thin layer, the upper layer is easy to obtain heat by radiation and convection, and the lower layer obtains heat by heat conduction of the glass liquid. The components in the batch material are easy to maintain uniform distribution, which increases the speed of glass formation. However, the traditional screw machine feeding is easy to form a thick material mountain in the feeding port area, which is not conducive to the melting of glass powder. Due to the continuous increase of the material mountain, the screw machine thrust is also required to increase, and the wear of the screw shaft increases. Not only does it need to replace the screw shaft regularly, but the excessively thick material mountain will not only affect the melting effect, but also the wear of the screw shaft will affect the product quality. Therefore, an automatic feeding device for a glass kiln is urgently needed to solve the above technical problems. Utility Model Content
