Description

A mixer for PE gas pipe production

technical field

The utility model relates to the technical field of PE gas pipe production, in particular to a mixing machine for PE gas pipe production.

Background technique

Mixing is the first process in the production of PE pipes and plays a very important role. In the process of extrusion, a conical twin-screw extruder is generally used, and its positive conveying effect is far greater than the mixing effect on materials. Therefore, The uniform mixing and kneading of various additives are mainly completed by the mixing before extrusion. A good mixer can compensate for an extruder with poor plasticizing performance, but an extruder with good plasticity cannot make up for the mixing. Therefore, the mixing degree of additives and raw materials plays a very important role in the production quality of pipes.

The mixer for PE gas pipe production is a device that mixes PE raw materials and plasticizers by stirring. The mixer in the prior art is equipped with a rotating shaft inside, and a paddle is installed on the rotating shaft, which is driven by a motor to plasticize. The mixing force is low, the stirring force is small, the mixing of the raw material and plasticizer is not sufficient, the temperature of the raw material cannot be increased, and the temperature of the raw material cannot be increased. Fully mixing will have an impact on the production quality of the subsequent PE gas pipes, which is not conducive to the production of PE gas pipes, thereby reducing the production efficiency of PE gas pipes; the mixer in the prior art directly mixes the additives and raw materials from the feed The pipeline is poured into the wheel feeder. The structure of the feeding pipeline is simple, the function of the feeding pipeline is single, and only a large amount of material can be fed. , the feeding pipeline cannot control the amount of incoming, so it is impossible to ensure that the amount of raw materials and plasticizers is the original amount, because the production of PE gas pipe has extremely high requirements on the amount of ingredients, and the excessive amount of ingredients will waste resources and increase costs. Too little dosage will affect the performance of the product, and mistakes in the batching work will have a great impact on the quality. For this reason, we propose a mixer for the production of PE gas pipes.

The angle formed by the bottom support plate is larger than the angle formed by the side support plate of the middle blade and the lower blade and the bottom support plate. Increasing the inclination angle can improve the pre-plasticizing effect. The bottom support plate of the upper blade is relative to the side support plate. For the inclined setting, in the process of circular motion, the inclined bottom support plate shears the raw material, and the side support plate spreads the raw material, which increases the shear strength and diffusion strength. When the force moves upward, the raw material in the middle of the blade moves downward, and the raw material stirred by the upper blade is thrown into the drum, the temperature rises, the raw material is deformed by the force, and the surface area of the raw material increases, thereby increasing the raw material and plasticizer.
