[0002] A screw machine is a machine with two parallel screws that rotate in left and right directions. It is used to transport various powdered, granular, small block materials, etc., and can transport materials horizontally or inclined. In the production process of automotive urea, the screw machine can transport the urea granules used in urea production to the mixer for processing.

[0003] For example, the Chinese patent publication number CN219688392U discloses a screw machine. The utility model provides a screw machine, which relates to the technical field of screw machines, and solves the problem that when a large number of urea granules are directly put into the processing equipment during use of the existing screw machine, a large number of urea granules are piled up together, resulting in poor mixing effect of urea granules and solution, which affects the production efficiency of automotive urea. The utility model includes: a main body, a motor is installed at the side end of the main body, a leg is installed at the bottom of the main body, and a discharge piece is installed at the bottom of the other side end of the main body; the discharge piece is a rectangular structure, and the discharge piece includes a paddle, and the top of the paddle is installed on the inner side of the discharge piece through a rotating shaft; a top plate, and the top plate is installed on the top of the main body. The paddle moves back and forth on the inner side of the discharge piece, and the paddle swings the urea granules back and forth to sprinkle them into the automotive urea processing equipment, so that the urea granules are evenly sprinkled into the equipment, preventing a large number of urea granules from gathering together to affect the efficiency of mixing with the solution, and improving the production efficiency of automotive urea.

[0004] However, in actual use, the screw machine conveys gas or other materials by rotating the screw. When the conveyed gas or material needs to be heated, it needs to rely on external heating equipment to heat it during or after conveying. It is not convenient to set a heating device on the outer casing used to protect the screw machine to improve the conveying and heating efficiency. Utility Model Content
