Technical Field

[0001] The utility model belongs to the technical field of dehydration equipment, and particularly relates to a polyurethane resin raw material pretreatment dehydration device. Background Art

[0002] In the production process of polyurethane resin, pretreatment dehydration is a key step. The purpose of this step is to remove the moisture in the raw materials to ensure the smooth progress of subsequent reactions and avoid the adverse effects of moisture on product quality;

[0003] Currently, the commonly used dehydration method for existing polyurethane resin raw materials is to heat the raw materials to a certain temperature to evaporate the moisture in them. This is usually carried out in a sealed reaction kettle or dryer, and a heat source is provided through a heating device (such as electric heating, steam heating, etc.). However, the heat source is distributed outside the equipment and heats from the outside to the inside, which results in the inner layer area of the raw materials not being effectively heated, affecting the dehydration efficiency. At the same time, the dehydration uniformity of the inner and outer layer raw materials is not easy to affect the production quality

[0004] To solve the above problems, a polyurethane resin raw material pretreatment dehydration device is proposed in this application. Content of the Utility Model

[0014] The utility model has the following beneficial effects:

[0015] The utility model uses a heater to cooperate with a heat conduction rod to transfer heat to the heating rod, so that the side plate can be heated to heat the raw materials inside the reaction tank, achieving a heating effect from the inside to the outside. It cooperates with the external equipment to form a double-layer heating and dehydration treatment inside and outside.
