Description

Squeeze dry pellet machine

technical field

The utility model relates to the technical field of recycling and reusing waste plastics, in particular to a drying pellet machine.

Background technique

With the rapid economic development, a large amount of waste plastics are produced every year. If they are not recycled and recycled, they will cause great pollution to the environment. And through the green treatment of waste plastic recycling and reuse, it can not only avoid pollution but also generate economic benefits. In the traditional technology, there are two equipment configurations for the recycling of waste plastics: the first is the waste plastic recycling granulator, which is generally only suitable for the plasticization and granulation of dry waste plastics with low water content. The water content requirement is relatively strict, so dehydration treatment is required before this. However, after being dehydrated by a dehydrator or a squeeze dryer, it needs to go through a set of relatively complicated conveying equipment before it can be docked with the waste plastic recycling granulator. Therefore, the waste plastic recycling granulator generally needs a supporting dehydrator before it can be used on site. However, dehydration and granulation cannot be separated. If the dehydration and granulation processes are separated, a large number of containers are needed to contain the dehydrated waste plastics. Therefore, the recycling cost of this kind of waste plastics is high; the second is the squeeze-drying pellet machine, which can squeeze and dehydrate the waste plastics, and then pre-granulate them. The obtained plastic particles have low water content and can be directly Granulated on the granulator, and the obtained plastic particles are convenient for storage and transportation, so that the granulation and dehydration processes are truly separated. The cost of this kind of squeeze dry pellet machine is low.

Extrusion pre-granulation in the traditional technology has the following disadvantages: the helical blade on the screw shaft has only a section of helical blade, which has poor extrusion and discharge effect on water; the heating device generates heat through electric heating, and transfers the heat to the material, so that the material is melted, this heating method consumes a lot of energy, the heat is lost in the process of transmission, and the efficiency is low; only one end of the screw shaft is fixed, and this method is relatively easy to cause the shaft to break; the discharge box is directly connected to the fan, relying on The fan pumps out the material to the collecting hopper. This method will lead to the unsmooth discharge of the material, which will cause the material to be blocked on the material cutting device, and the machine will be stuck. After the shutdown, the material needs to be cleaned before it can be started again.
