During the use of the machine, the material that needs to be cooled enters the conveyor inner shell 2 through the feed hopper, and the staff opens the pipelines of the cooling water inlet 1 3 and the cooling water inlet 2 5 at the same time. The coolant input through the cooling water inlet 1 3 enters the inner cavity of the spiral shaft 13, and cools the material from the inside. The coolant after absorbing heat is output through the cooling water outlet 1 4 for refrigeration. The coolant input through the cooling water inlet 2 5 enters the sealed cavity between the conveyor outer shell 1 and the conveyor inner shell 2, and cools the material from the outside. The coolant after absorbing heat is output through the cooling water outlet 2 6 for refrigeration.

[0027] Working principle: During the use of the screw conveyor, the material that needs to be cooled enters the conveyor inner shell 2 through the feed hopper, and the staff opens the pipelines of the cooling water inlet 1 3 and the cooling water inlet 2 5 at the same time. The coolant input through the cooling water inlet 1 3 enters the inner cavity of the spiral shaft 13, and cools the material from the inside. The coolant after absorbing heat is output through the cooling water outlet 1 4 for refrigeration. The coolant input through the cooling water inlet 2 5 enters the sealed cavity between the conveyor outer shell 1 and the conveyor inner shell 2, and cools the material from the outside. The coolant after absorbing heat is output through the cooling water outlet 2 6 for refrigeration. The drive motor 9 works to drive the drive shaft 10 to rotate, and the drive shaft 10 drives the driven shaft 12 to rotate through the transmission chain belt 11. The driven shaft 12 drives the screw shaft 13 to rotate and pushes the material inside the screw conveyor. During the material conveying process, the material with higher temperature exchanges heat with the screw shaft 13 with lower temperature and the inner shell 2 of the conveyor. The synchronous cooling structure on the inside and outside increases the cooling area of ​​the material, and realizes uniform cooling of the material under the circulation of the coolant. The temperature sensor probe 14 detects the temperature of the material at the discharge port 16, and adjusts the amount of cooling water entering the screw conveyor through temperature feedback to achieve the purpose of controlling the required temperature. When the material temperature is too high, the pipeline of the spray cooling interface 7 can be opened in time, and the cooling water can be sprayed through the nozzle 15, so that the cooling water is in direct contact with the material, and the material is quickly forced to cool, which has a protective effect.
