Polyurethane double-layer thermal insulation tank

Abstract

The invention discloses a polyurethane double-layer thermal insulation tank. According to the technical key points, the polyurethane double-layer thermal insulation tank comprises a tank body and a tank cover, a stirring shaft is arranged inside the tank body, a driving part connected with the stirring shaft is arranged on the tank cover, a discharging valve is arranged at the bottom of the tank body, and a liquid level measuring device is arranged inside the tank body; a controller, a displayer and a switch group are arranged outside the tank body, the controller is connected with the drivingpart, the liquid level measuring device, the displayer and the switch group, the displayer is used for displaying parameters and working states of polyurethane in the tank body, and the switch groupis used for inputting a control signal to control the tank body; the tank body is made of magnetic materials, a coil is arranged on the outer side of the tank body, the coil is arranged along the tankbody in a spiral mode, a gap is formed between the coil and the tank body, the lowest point of the coil and the lowest point of the tank body are positioned on the same horizontal plane; an the highest point of the coil and the highest liquid level of the liquid in the tank body are positioned on the same horizontal plane. According to the polyurethane double-layer thermal insulation tank, the upper part and the lower part of the tank body can be uniformly heated, so that the stirring uniformity of the polyurethane in the tank body is consistent.

Description

technical field [0001] The invention relates to the field of polyurethane injection molding equipment, in particular to a polyurethane double-layer thermal insulation tank. Background technique [0002] Polyurethane needs to be stirred in the tank during the production process. During the stirring process, the polyurethane in the tank needs to be continuously heated.

[0002] Polyurethane needs to be stirred in the tank during the production process. During the stirring process, the polyurethane in the tank needs to be continuously heated. The polyurethane electric heating tank includes a tank body and a tank cover. There is a stirring shaft in the tank and a drive on the tank cover. The motor and reducer that the stirring shaft rotates, the tank body and the tank cover are fixed by the flange plate, the heating device is installed at the bottom, the heat is conducted from bottom to top, the temperature at the bottom is high, and the temperature at the top is low. During the stirring process, the stirring shaft rotates and stirs at the same time For the polyurethane above and below, the temperature at the bottom is high and the temperature at the top is low, and the uniformity of stirring up and down appears to be different, which affects the injection molding efficiency and injection molding effect.
