Description

Technical Field

[0001] The utility model relates to the technical field of internal mixer conveying devices, in particular to an inclined lifting type conveying auger. Background Art

[0002] Closed plastic mixer is referred to as internal mixer. The main component of internal mixer is internal mixing chamber, also called plastic mixing chamber. The upper part is feeding device, the lower part is unloading device port, and there is a top bolt on the upper and lower parts. When the upper and lower top bolts are closed, a closed plastic mixing chamber is formed. When internal mixer is used in building materials, chemical industry, electric power, metallurgy, coal, food and other industries, it is often necessary to heat the mixed materials. The mixed materials will be transported in a fluid state by auger conveyor. During the transportation process, the material is easy to harden due to the drop in temperature.

[0003] After searching, the Chinese patent "Antifreeze Conveying Auger" with the publication number "CN215247586U" is found. In this patent, an electric heating belt is added to the surface of the conveying auger to heat the surface of the auger and keep the materials inside the auger warm. However, this patent sets the electric heating belt on the surface of the auger. The contact between the electric heating belt and the air will cause unnecessary heat loss, and the insulation efficiency is low.

[0004] Therefore, an inclined lifting type conveying auger is proposed to solve the above problems. Utility Model Content

When in use, the mixed fluid material enters the auger tube through the feeding port, and then the motor is started, and the output shaft of the motor drives the rotating tube and the auger blades to rotate, and the auger blades convey the fluid material. At the same time, the spiral heating rod in the heating tank is started and heats and insulates the fluid material through the auger tube, thereby preventing the heat generated by the spiral heating rod from being directly dissipated into the air, avoiding unnecessary heat loss, and improving the heating and insulation efficiency of the device.
