Description

Technical Field

[0002] Screw conveyors have the characteristics of simple structure, small cross-sectional size, good sealing, reliable operation and low manufacturing cost. They are convenient for intermediate loading and unloading, the conveying direction is reversible, and they can also convey in two opposite directions at the same time. During the conveying process, the materials can also be stirred, mixed, heated and cooled. The material flow rate can be adjusted through the loading and unloading gates. Therefore, screw conveyors are widely used in various sectors of the national economy such as the grain industry, building materials industry, chemical industry, machinery manufacturing industry, and transportation industry.

[0003] However, a certain gap must be maintained between the conveyor's spiral blades and the outer shell to ensure smooth operation of the spiral, but this will cause the material to stay at the bottom and on both sides. When the spiral is running, it will compact the material adhering to the outer shell, so that the material adhering to the outer shell will become solid as the running time increases, affecting the spiral conveying efficiency and accelerating the wear of the spiral blades. Also, because it is inside the spiral, it is difficult to clean. Utility Model Content

[0034] When the device is in use, the upper and lower flexible tubes 107 are connected to external devices respectively, and the material enters the conveying pipe 104 from the feed pipe 105. The reduction motor 112 is started to drive the conveying screw 110 to rotate. The material is moved to the discharge pipe 106 under the push of the conveying screw 110 and then output. When the inner wall of the conveying pipe 104 has serious material adhesion, the silo wall vibrator 113 is started, vibrated for 3 to 5 seconds and then turned off. The silo wall vibrator 113 is repeatedly turned on and off until the compacted accumulated material inside is separated from the inner wall of the trough. During this period, gas can be introduced into the compressed air interface 109, and the gas enters the conveying pipe. 104 pushes the silicone film 210 on the inner side of the push plate 209, so that the telescopic tube 207 is pushed into the inside of the slide groove 204, and the spring 206 is compressed, and the blind hole 208 is gradually aligned with the outlet pipe 203. At this time, the gas passes through the blind hole 208 and the outlet pipe 203 and flows to the side of the conveying spiral 110, and flushes and peels off the surrounding materials attached to the feeding pipe 204. After observing that the accumulated materials are transported out, the compressed air outside is purged for a period of time. At this time, the spring 205 pushes the telescopic tube 207 to reset, and the outlet pipe 203 is closed by the telescopic tube 207 to prevent the material from splashing into the inside of the telescopic tube 207.
