A polyurethane double-layer thermal insulation tank

Abstract

The invention discloses a polyurethane double-layer thermal insulation tank. The technical points are: a tank body and a tank cover, a stirring shaft set in the tank body, a driving part connected to the stirring shaft on the tank cover, a discharge valve at the bottom of the tank body, and a liquid level measuring device in the tank body. The outside of the tank is also provided with a controller, a display and a switch group. The controller is respectively connected with the driving part, the liquid level measuring device, the display and the switch group. The display is used to display the parameters and working status of the polyurethane in the tank, and the switch group is used to input The control signal controls the tank. The tank is made of magnetic material. A coil is arranged on the outside of the tank. The coil is spirally arranged along the tank. There is a gap between the coil and the tank. The lowest point of the coil and the lowest point of the tank are on the same level. , the highest point of the coil is at the same level as the highest liquid level in the tank. The invention can uniformly heat the top and bottom of the tank body so that the polyurethane in the tank body is uniformly stirred.

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] In the production process of polyurethane, the tank body needs to be stirred. During the stirring process, the polyurethane in the tank needs to be continuously heated. The polyurethane electric heating tank body includes a tank body and a tank cover. The tank body is provided with a stirring shaft. The motor and reducer for the rotation of the stirring shaft, the tank body and the tank cover are fixed by the flange plate, the heating device is arranged at the bottom, the heat is conducted from the bottom to the top, the temperature below is high, and the temperature above 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,...

Problems solved by technology

[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.
