technical field

The invention relates to the technical field of PVC pipes, in particular to a high-efficiency cooling and mixing device for PVC pipes.

Background technique

The raw materials need to be mixed before making PVC pipes. The mixing process of PVC raw materials is usually divided into hot mixing and cold mixing. Cold mixing is a process of rapidly cooling the raw materials after hot mixing. The existing cold mixing equipment usually adopts a separate drive mode Drive the stirring device. When too many raw materials are added to the cold mixing equipment and the viscosity of the raw materials is too large, it is easy to cause the driving equipment to be damaged due to overloading, reduce the service life of the driving equipment, and virtually reduce the cooling rate. The working efficiency of the mixing equipment; the current cold mixing equipment usually uses cooling water to reduce the temperature of the outer end of the mixing device, so as to achieve the cooling effect of the raw materials. This method is not only old-fashioned but also has a low cooling speed, which greatly reduces the working efficiency of the equipment; In the cavity, since the stirring frame is set at a certain height from the bottom end of the stirring cavity, this will cause the accumulation of raw materials at the bottom end of the stirring cavity, which will reduce the stirring efficiency of the equipment. The stirring device in the device adopts a frequency modulation motor and a driving motor to drive the rotating shaft and the stirring chamber respectively, so that the stirring effect is better. This dual-drive method can avoid the situation of adding too many raw materials and excessive raw material viscosity in the cold mixing equipment. Occasionally, it will cause overload and damage to the driving equipment. At the same time, the auxiliary stirring device provided can also avoid the accumulation of raw materials at the bottom end of the stirring chamber. The cooling system in this device adopts a double cooling method, which not only has a novel structure, but also reduces the temperature. The speed is also greatly improved, and the working efficiency of the equipment is also improved.
