Glass kiln raw material feeding system and feeding method thereof

Abstract

The invention belongs to the field of glass manufacturing, and particularly relates to a glass kiln raw material feeding system and a feeding method thereof. The feeding system comprises a multi-station progressive shovel type feeding device, a control detecting unit and a pool furnace, wherein the multi-station progressive shovel type feeding device feeds a raw material with a set weight into theset position in the pool furnace through a feeding port under the control of the control detecting unit. According to the present invention, by using the feeding method of the feeding system, the feeding amount can be precisely controlled, and the multi-position feeding can be achieved, such that the method has advantages of uniform feeding, flat material stacking and high control precision.

Description

technical field [0001] The invention belongs to the field of glass manufacturing, and in particular relates to a glass kiln raw material feeding system and a feeding method. Background technique [0002] In the glass production process, the requirements for the accuracy of raw material feeding control are getting higher and higher. The feeding control mentioned here includes feeding devices, feeding methods, etc. The control of feeding directly affects the quality of glass melting. High feeding accuracy can ensure that the kiln The liquid level in the furnace is stable, the material mountain is evenly distributed, and the temperature in the hot spot area is easy to control, which is conducive to the improvement of glass quality. In addition, the thickness of the batch material layer in the kiln affects the melting speed of the batch material and the production capacity of the kiln to a large extent. When the batch material is fed in a thin layer, the upper layer is easy to o...

Problems solved by technology

In addition, the thickness of the batch material layer in the kiln affects the melting speed of the batch material and the production capacity of the kiln to a large extent. 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 is made of glass. The heat is obtained by liquid heat conduction, and the components in the batch are easy to keep evenly distributed, which increases the glass forming speed, while 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 thrust of the screw machine is also increased, and the wear of the screw shaft increases. Not only does the screw shaft need to be replaced regularly, but the material mountain that is too thick will affect the melting effect, and the wear on the screw shaft will also affect the product quality.
