Description

Technical Field

[0001] This utility model relates to the field of photovoltaic glass production equipment technology, specifically a kiln hopper with anti-sticking material. Background Technology

[0002] In the photovoltaic glass production process, the main method of furnace feeding is to add the batch material into a silo for storage, and then continuously convey it into the furnace for high-temperature melting via a screw feeder. The silo is installed close to the furnace body. Due to the high temperature environment of the furnace and the presence of moisture in the batch material, the batch material stored in the silo is prone to clumping and sticking to the inner wall of the silo due to moisture evaporation. This causes the screw feeder to fail to deliver the batch material into the furnace due to clumping, or the clumping may become stuck in the middle of the screw feeder, increasing the equipment load and causing shutdowns. Furthermore, the material sticking to the silo requires regular emptying and cleaning by personnel, increasing workload. To solve this technical problem, a furnace silo with anti-sticking design is proposed. Utility Model Content

[0023] See Figure 1 As shown, Figure 1 This is a side view of a valve switching tool according to an embodiment of the present invention. In the photovoltaic glass production process, the main method of furnace feeding is to add the batch material into a silo for storage, and then continuously convey it to the furnace for high-temperature melting via a screw feeder. The silo is installed close to the furnace body. Due to the high temperature environment of the furnace and the presence of moisture in the batch material, the batch material stored in the silo is prone to clumping and sticking to the inner wall of the silo due to moisture evaporation. This causes the screw feeder to fail to deliver the batch material into the furnace due to clumping, or the clumping may get stuck in the middle of the screw feeder, increasing the equipment load and causing equipment shutdown. Furthermore, the sticking material in the silo requires regular emptying and cleaning by workers, increasing their workload. To solve this technical problem, a furnace silo with anti-sticking properties is proposed.
