Description

Technical Field

[0001] The utility model relates to the technical field of overflow method substrate glass manufacturing, in particular to a feeding device for a small material bin of a substrate glass kiln feeder. Background Art

[0002] For a long time, overflow substrate glass furnaces have adopted spiral feeders for continuous feeding, mainly because spiral feeders have the following technical advantages: 1. Simple and compact structure; 2. Stable and reliable operation; 3. Accurate feeding amount; 4. Good airtightness is conducive to the stability of furnace pressure and the environment around the kiln; 5. Due to the stirring effect of the spiral shaft, the mixture is further mixed and homogenized during the feeding process.

[0003] During the use of the screw feeder, its feeding capacity will change with the wear or burning of the screw shaft and water cooling jacket, changes in the characteristics of the mixed material, and changes in its own electromechanical performance. Therefore, it is necessary to conduct daily inspection, maintenance and care for the screw feeder in operation, and formulate a replacement cycle based on the performance of the feeder, and implement replacement and maintenance according to the cycle. This situation belongs to the regular replacement of the feeder.

[0004] In order to ensure the stability of the pool furnace process, the feeder needs to operate continuously and stably for a long time. Even if the feeder is fully maintained, it may suddenly fail due to other factors and need to be replaced urgently. This situation belongs to the emergency replacement of the feeder. Several common sudden failures of the feeder are: 1. The front end of the water cooling jacket is seriously worn, and even penetrated and leaked; 2. The spiral shaft is blocked and stopped, which is manifested as an abnormal increase in the current of the feeder; 3. The spiral shaft is broken or the transmission fails, which is manifested as an abnormal decrease in the current of the feeder.

[0005] After the existing screw feeder is installed, under normal circumstances, the feed pipe is filled with the mixture, so the screw shaft is covered by the mixture, which can effectively protect the feed pipe and the screw shaft from being burned by the high-temperature gas of the kiln. On the contrary, when the feed pipe is in an empty state, due to the positive pressure inside the kiln, the high-temperature gas in the kiln will enter the feed pipe through the feed port, burning the mechanical and instrument components of the feeder, and in severe cases causing irreparable equipment damage. Therefore, when the feeder is replaced, the feed pipe and the small feed bin of the feeder must be filled with the mixture before the standby feeder enters the working position.

[0006] Due to the requirements of batching and melting process, the moisture content of the substrate glass mixture needs to be maintained at a very low level. Specifically, the moisture content is required to be controlled within 0.5%, and the mixture itself has the physical property of being extremely easy to absorb moisture and agglomerate. Therefore, the mixture loaded in the small silo and the material pipe of the feeder cannot be left stationary for a long time, generally speaking, not more than 8 hours, otherwise the mixture will agglomerate inside the material pipe and cause the feeder to block or get stuck when it is started. Ultimately, the agglomerated material must be cleaned out before it can be put into use, which undoubtedly delays the inevitable replacement of the feeder and brings potential risks to the stability of the pool furnace process.

[0007] Therefore, when replacing the feeder in actual production, the small feed bin and feed pipe of the feeder to be replaced must be in a mixed material filling state, and must be filled immediately after replacement.

[0008] The existing method and process of adding materials to the small silo of the feeder in standby mode is as follows: 1. Manually use a hydraulic forklift to transfer the mixture from the storage room on the fifth floor to the furnace front area on the fourth floor; 2. Then manually add the mixture to the small silo of the feeder. The whole process requires at least 2 people to cooperate in the operation and takes at least 10 minutes. It is time-consuming, labor-intensive and inefficient, especially when the feeder is replaced in an emergency, which delays the precious emergency processing time, which is very unfavorable to the stability of the pool furnace process and quality.

[0009] Therefore it is necessary to design a time-saving, labor-saving and more efficient feeding device to solve this problem. Utility Model Content
