Figure 2 is a schematic structural diagram of a conveying assembly according to a first embodiment of the utility model. Figure 3 It is a structural schematic diagram of the top cover and the heating component of the first embodiment of the utility model. The utility model provides a polyurethane raw material preheating and conveying device, including a conveying tank 101 and a top cover 102, a conveying component, a heat preservation component and a heating component.

It can be understood that the above-mentioned scheme can be used in the scenario of preheating and conveying polyurethane raw materials, and can also be used to solve the stirring problem during transportation.
[0021] According to the present specific embodiment, the top cover 102 is located above the conveying tank 101, the motor 103 is fixedly connected to the top cover 102 and is located on the top of the top cover 102, the rotating shaft 104 is connected to the motor 103, passes through the top cover 102 and is located inside the conveying tank 101, the spiral conveying plate 105 is fixedly connected to the rotating shaft 104 and is located inside the conveying tank 101, a feed port 106 is provided at the bottom of the conveying tank 101, the heat preservation component is connected to the conveying tank 101, and the heating component is connected to the top cover 102. The cover 102 is connected, the conveying tank 101 is used to convey the polyurethane raw material, and the top cover 102 is used for sealing the device. The polyurethane raw material is heated during conveying through the heating component. When the polyurethane raw material is conveyed, the polyurethane raw material is input into the conveying pipe through the feed port 106. The rotation of the motor 103 drives the rotating shaft 104 and the spiral conveying plate 105 to rotate, and at the same time drives the polyurethane raw material to move slowly upward along with the spiral conveying plate 105. In the process of moving, the polyurethane raw material is fully heated, thereby reducing the situation where the polyurethane raw material is not fully heated.
[0022] Among them, the number of the support rods 107 is two, the two support rods 107 are fixedly connected to the rotating shaft 104, and are respectively located between the top cover 102 and the conveying tank 101; the number of the pressing plates 108 is two, the two pressing plates 108 are fixedly connected to the support rods 107, and are respectively located on the outside of the conveying tank 101. When the polyurethane raw material rises to the top of the conveying tank 101 along with the spiral conveying plate 105, the support rod 107 rotates with the rotating shaft 104, and at the same time drives the pressing plate 108 to rotate. The polyurethane raw material above the conveying tank 101 is pressed down along the insulation tank 110 by the pressing plate 108, thereby achieving the purpose of conveying the polyurethane raw material.
[0023] Secondly, the base 109 is fixedly connected to the conveying tank 101 and is located at the bottom of the conveying tank 101. The insulation tank 110 is fixedly connected to the base 109 and is located on the outside of the conveying tank 101. The base 109 provides support for the device, and the insulation tank 110 provides insulation for the polyurethane raw material.
[0024] Again, the heater 111 is fixedly connected to the top cover 102 and is located on the top of the top cover 102.

The connecting tube 112 is used to provide heat conduction for the heater 111. The insulation tank 110 is heated by the spiral heating tube 113, and the polyurethane raw material inside the tank body is heated by the insulation tank 110.

During the movement, the polyurethane raw material is fully heated, thereby reducing the situation where the polyurethane raw material is not sufficiently heated. This solves the problem that when the polyurethane raw material preheating and conveying device is in use, the polyurethane raw material is added into the tank from above, and the polyurethane raw material is easily affected by gravity and falls directly to the bottom of the tank from the gap of the stirring mechanism, resulting in insufficient heating of the polyurethane raw material, which affects the processing quality of the polyurethane.
