However, the material cooling distance of this cooling mechanism is relatively short, and the structure has room for improvement. Therefore, the structure of this cooling mechanism needs further refinement. Summary of the Invention

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: This double-spiral mobile cooler includes a housing, and rollers are provided at the bottom of the housing. The housing is characterized by having a U-shaped material cavity, an inlet at the upper end of the U-shaped opening of the material cavity, and an outlet at the lower end of the U-shaped opening. A double-spiral structure capable of pushing material from the inlet to the outlet is provided in the material cavity. The drive shaft of the double-spiral structure passes through the housing and is connected to a driver. A cooling chamber capable of allowing cooling water to flow is provided inside the housing. The cooling chamber covers the outer wall of the material cavity. An inlet is provided at one end of the cooling chamber, and an outlet is provided at the other end.

[0005] As an improvement, the double helix structure may preferably include two helical shafts, which are respectively inserted into the material cavity and arranged vertically and parallel to each other.

[0006] In a further improvement, the helical shaft may preferably include a cylindrical drive shaft and helical blades disposed on the surface of the drive shaft. A sealing seat is fitted into the end opening of the drive shaft. The sealing seat is connected to the side wall of the housing. A core tube that allows cooling water to be introduced into the inner cavity of the drive shaft is inserted through the sealing seat.

[0007] In a further improvement, the sealing seat may preferably include a shaft end assembly and a bearing housing, the shaft end assembly passing through the housing and covering the end opening of the drive shaft, the bearing housing being welded to the housing and fitted onto the shaft end assembly, and the core tube passing through the shaft end assembly and extending into the inner cavity of the drive shaft.

[0008] As a further improvement, a rotary joint can preferably be provided at the end of the core tube, and the inner cavity of the core tube is connected to the inner cavity of the rotary joint.

[0012] As a further improvement, the housing may preferably be provided with a baffle plate that can close the opening at the end of the jacket.

[0013] As an improvement, a feeding port capable of feeding different types of materials can preferably be provided on the side wall of the shell near the inlet.

[0014] Compared with the prior art, the advantages of this utility model are as follows: the material chamber adopts a U-shaped structure. After the material enters from the feed port, it is pushed out from the discharge port by the double helix structure and moves along the U-shaped path in the shell. The material chamber is covered with a cooling chamber, in which cooling water can be introduced, which increases the cooling distance of the material, realizes the full cooling of the material, and reduces the phenomenon of high-temperature coking of the material. The material is naturally discharged and propelled forward by the double helix structure, eliminating the use of the feed pump, reducing the energy consumption of material feeding, and reducing cooling costs. The double helix structure adopts a hollow structure, which can also be circulated with cooling water, further improving the cooling effect. Attached Figure Description
