A first conveying pipe and a second conveying pipe are provided between the head box and the tail box. The first conveying pipe is provided with an inlet and an outlet. The conveying chain is provided with a chain plate. A head sprocket engaged with the conveying chain is rotatably provided in the head box, and a tail sprocket engaged with the conveying chain is rotatably provided in the tail box.

In the process of conveying materials by the pipe chain conveyor, the condensation on the inner wall of the conveying pipe can easily affect the quality of the materials.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. Example

[0020] A tube chain conveyor, such as Figure 1 As shown, it includes a conveyor chain and several chassis 1, wherein the chassis 1 on the two sides are the head chassis and the tail chassis respectively. Two pipe bodies 2 for accommodating the conveyor chains passing through are provided between adjacent chassis 1, and the conveyor chains move in opposite directions in the two pipe bodies 2. After powder and other materials are placed in the head chassis, the chain plates on the conveyor chain will convey the materials along the pipe body 2 to the tail chassis for discharge, and the empty pipe chain will move along the other pipe body 2 back to the head chassis for continuous feeding.

[0021] like Figure 1As shown, a heating component for heating the pipe body 2 is provided outside the pipe body 2. The pipe body 2 is heated by the heating component, so that the condensed water on the inner wall of the conveying pipe evaporates in humid weather. After opening the material ports on the chassis 1 at both ends, the pipe chain conveyor is started to drive the internal air flow to remove the influence of the condensed water. Then the pipe chain conveyor can carry out normal material transportation, ensuring the quality of the material. Specifically, the heating component includes an electric heating strip 3 and a power supply 4 for supplying power to the electric heating strip 3 to make it heat up. The power supply 4 is fixed to the chassis 1 by screws. When the power supply 4 is started, the electric heating strip 3 can be supplied with power and heat can be generated through resistance to heat the pipe body 2 and remove moisture from the pipe body 2.

[0022] Further, such as Figure 1 The electric heating strip 3 is flexible and is arranged in a flat shape and fits the outer wall of the pipe body 2. The flexible electric heating strip 3 can better fit the outer wall of the pipe body 2, and the flat electric heating strip 3 has a larger area in contact with the pipe body 2, thereby having a better and faster heating effect and can efficiently remove moisture in the pipe chain conveyor. Furthermore, the electric heating strip 3 is spirally wound on the outer wall of the pipe body 2. Since the electric heating strip 3 is flexible, the electric heating strip 3 can be relatively easily spirally wound on the outer wall of the pipe body 2. The spiral winding method has a better heating effect on the pipe body 2 on the one hand, and can be easily fixed on the pipe body 2 by winding, and the fixing effect is good. The electric heating strip 3 is provided with two spiral sections 5, and the two spiral sections 5 are respectively wound around the two pipe bodies 2 between the adjacent chassis 1. One electric heating strip 3 can heat the two pipe bodies 2 without installing more electric heating strips 3, and the heating of the two pipe bodies 2 can be controlled by the same power supply 4, which is more convenient.

[0023] like Figure 1 and Figure 2 As shown, the electric heating strip 3 includes two heat-conducting splints 6 and a heating wire 7. The heating wire 7 is located between the two heat-conducting splints 6. The heating wire 7 is powered by the power supply 4. After the heating wire 7 is powered and heated, it can conduct heat to the heat-conducting splints 6 and conduct heat to the pipe body 2 through the heat-conducting splints 6. The larger area of ​​the heat-conducting splints 6 relative to the heating wire 7 is utilized to heat a large area of ​​the pipe body 2, thereby improving the heating effect. Specifically, the heat-conducting splints 6 are thin aluminum sheets, and the two sides of the two thin aluminum sheets are welded and fixed. The thin aluminum sheets are easy to bend, so that the electric heating strip 3 can be easily wrapped around the outer wall of the pipe body 2. Moreover, the thin aluminum sheet has good thermal conductivity due to the aluminum material, and can quickly conduct the heat on the heating wire 7 to the pipe body 2, thereby efficiently heating the pipe chain conveyor. After the two sides of the two thin aluminum sheets are welded and fixed, the strength of the electric heating strip 3 can be guaranteed.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
