It is of poor quality, the mass defects such as crazing, speckle and bubble are occurred using plastic part made from this plastic grain.
The content of the invention
In order to overcome the above problem, the utility model provides one kind and is able to ensure that the uniform engineering plastics of drying are set with heated drying
It is standby.
To achieve the above object, the technical solution of the utility model offer is：
A kind of engineering plastics hot drying equipment, including drying baker, put hopper and agitating shaft；The hopper of putting is arranged on
In drying baker, put hopper and leave space with drying chamber interior wall, the bottom of drying baker is provided with air inlet and air outlet；Described puts
Hopper is broach hopper wide at the top and narrow at the bottom, puts and some air inlets are provided with the wall of hopper, puts and is provided with material at the top of hopper
Import and damp exit；The agitating shaft, which is arranged on, to be put inside hopper, and agitating shaft includes helix tube axis, in the side of helix tube axis
It is distributed with some agitating vanes on wall, the helical angle between some agitating vanes is identical with pitch, between adjacent agitating vane
It is provided with column and breaks cut piece.
It is provided with air flow channel in the bottom for putting hopper, air flow channel and puts and be provided with sieve, air between hopper
Gas flow direction direction in runner puts the damp exit of hopper.
In the heating rod that is internally provided with of the helix tube axis, the junction of agitating vane and helix tube axis is provided with hot biography
Guiding element.
Above-mentioned technical proposal is beneficial in that：
The utility model provides a kind of engineering plastics hot drying equipment, due to being to transmit heat medium in drying baker,
Heated by the opposed hopper of heat medium, and part heat medium can be entered by air inlet and put in hopper, so may be used
With the contact area for maximumlly improving heat medium or putting hopper and plastic grain, drying efficiency is improved；And due to putting
Agitating shaft is provided with hopper, agitating vane and broken cut piece are provided with agitating shaft, agitating vane is different with the shape of broken cut piece,
It agitating shaft is formed the opposite stirring in both direction to plastic grain, make the rotation of 360 ° of plastic grain hair, this
Sample may insure that all areas of all plastic grains can be fully oven-dried, and realizes and dries uniform purpose, to ensure
Obtained plastic grain quality is high, is made after plastic part the defects of being not in crazing, speckle and bubble, and with excellent resistance to
High temperature and wear-resisting property.
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is the utility model part of the embodiment, instead of all the embodiments.Based on the embodiment in the utility model, ordinary skill
Personnel's all other embodiments obtained without making creative work, belong to the scope of the utility model protection.
Brief description of the drawings
Fig. 1 is 1 structure diagram of the utility model embodiment；
Fig. 2 cuts open figure figure for 1 helix tube axis of the utility model embodiment.
