Description

technical field [0001] The invention relates to the field of PVC pipes, in particular to a high-efficiency thermal mixing device for raw materials of PVC pipes. Background technique [0002] Before making PVC pipes, the raw materials need to be mixed. The mixing process of PVC raw materials is usually divided into two steps: hot mixing and cold mixing. Hot mixing is to mix PVC and various additives in a hot mixer and heat them below the softening temperature. The heating temperature during hot mixing can generally reach 100°C or even higher. Existing thermal mixing devices usually use motor-driven stirring paddles to operate. When the raw materials are stirred at high speed, they rub against each other to generate a large amount of heat energy, so as to achieve the purpose of mixing and semi-plasticizing the raw materials. However, this method is not only time-consuming and energy-intensive , low efficiency, and it is difficult to control the reaction temperature; when prob...

Problems solved by technology

Existing thermal mixing devices usually use motor-driven stirring paddles to operate. When the raw materials are stirred at high speed, they rub against each other to generate a large amount of heat energy, so as to achieve the purpose of mixing and semi-plasticizing the raw materials. However, this method is not only time-consuming and energy-intensive , low efficiency, and it is difficult to control the reaction temperature; when problems such as excessive raw material input and high viscosity of raw materials in the thermal mixing device occur, the driving equipment will be damaged due to overload and the service life of the driving equipment will be reduced; the traditional thermal mixing device The mixing device usually uses the way of free flow to export the raw materials, which not only wastes time but also is prone to blockage when the raw materials are exported, so now there is a need for a high-efficiency thermal mixing device for PVC pipe raw materials. The thermal mixing device in this equipment adopts a double drive method , the frequency modulation motor drives the rotating shaft and the stirring paddle to operate, and the rotating motor drives the driving gear and the elongated roller to operate. This design not only greatly improves the efficiency of raw material mixing and semi-plasticizing, but also avoids excessive input of raw materials in the thermal mixing device. Problems such as high viscosity of raw materials will cause damage to the driving equipment and improve the service life of the driving equipment. The heating plate and temperature detector are equipped to improve the heating efficiency of the equipment and also control the reaction temperature of the raw materials. Some auxiliary material guide devices make the raw material export quickly, avoid the occurrence of blockage when raw material is exported, and also greatly save the time of raw material export, and improve the working efficiency of the equipment
