Abstract

The invention discloses a polyurethane foaming device and a using method thereof. The polyurethane foaming device comprises a tank, a disturbance plate and a sieve tray. The top end of the tank is fixedly connected with a top cover through a flange, and the sieve tray is fixed between the tank and the top cover in a pressing joint mode. The power output end of a speed reducer is connected with a stirring shaft, and a spiral blade and a fixing rod are welded and fixed to the stirring shaft. The disturbance plate is welded and fixed to the fixing rod, and the other side of the top cover is connected to a vacuum pump through a connecting pipe. A motor drives the stirring shaft to rotate at a low speed, a foaming raw material is vertically transported from the bottom to the upper portion in the tank through the spiral blade, the foaming raw material is stirred in the horizontal direction through the disturbance plate, the foaming raw material is filtered in the stirring process, the interior of the tank is vacuumized through the vacuum pump, bubbles in the foaming raw material are broken through vacuum, and thus the foaming quality is improved.

Description

technical field [0001] The invention belongs to the technical field of polyurethane foaming devices, and in particular relates to a polyurethane foaming device and a using method thereof. Background technique [0002] The polyurethane composite material needs to go through the process of foaming and stirring during the production process. During the polyurethane foaming process, a large amount of heat will be generated, which needs to be dissipated in time. [0003] For example, the patent application number CN201720123301.2 discloses a high-speed cooling and foaming device for producing polyurethane composite materials, including at least two reactors arranged side by side, at least one of which is provided with a stirring device, The stirring device is connected with the driving device, a feed circulation port and a material discharge circulation port are provided at the bottom of each reactor, and each feed circulation port communicates with the discharge circulation port...
