Abstract
The utility model is related to a kind of double-screw type melting extruder exhaust system, with preceding exhaust hood and rear exhaust hood；The preceding exhaust hood is arranged on the direct current generator of double-screw type melting extruder, and the rear exhaust hood is arranged on above the discharging opening mould of double-screw type melting extruder, and its top is connected with delivery pipe；Connected between rear exhaust hood and double-screw type the melting extruder by support.This double-screw type melting extruder exhaust system is simple in construction, on the one hand the carbon brush powder in direct current generator can be suctioned out working region, ensure product quality, on the other hand the pernicious gas discharged at discharging opening mould can be discharged, ensure that workshop air is not easily susceptible to pollution, it is ensured that the health of staff.
Description
Technical field
The utility model is related to plastic particle processing field, more particularly to a kind of double-screw type melting extruder air draft system
System.
Background technology
Plastic pellet, is being commonly called as plastic grain, is that plastics are stored with semi-finished product form, transported and machine-shaping
Raw material.The particle of different particle or heterogeneity is carried out after mixing batch mixing, then by double-screw type smelting furnace extruder
Carry out wire drawing, cooling, be cut into particle again, it is mechanically actuated from raw material to particle is made.
The main machine structure of double screw extruder is by extrusion system, heating and cooling system, charging system and transmission system etc.
Composition.One end of existing double screw extruder is provided with the transmission system based on direct current generator, and its effect is carried to screw rod
For required moment of torsion and rotating speed；The other end is provided with discharging opening mould, can plastify into plastics by extrusion system uniform
Melt, and by screw rod is continuous, level pressure, constant temperature, quantitatively extrude discharging opening mould, pass through discharging opening mould and realize sizing.
Because the direct current generator on double-screw type melting extruder easily produces carbon brush powder, if into can shadow after feeding warehouse
Ring product quality, in addition, plastics after plasticizing is in solution due to temperature rise, certain pernicious gas can be produced, these gases
It can be discharged at discharging opening mould, pollute workshop air quality.
The content of the invention
Technical problem to be solved in the utility model is to provide one kind can be to double-screw type melting extruder power train
System is cleaned and can exclude the double-screw type melting extruder exhaust system of pernicious gas.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：A kind of double-screw type
Melting extruder exhaust system, with preceding exhaust hood and rear exhaust hood；The preceding exhaust hood is arranged on double-screw type melting extrusion
On the direct current generator of machine, the rear exhaust hood is arranged on above the discharging opening mould of double-screw type melting extruder, and its top connects
It is connected to delivery pipe；Connected between rear exhaust hood and double-screw type the melting extruder by support.
Preferably, the support is made up of upper connecting rod and lower link, its side is in " T " font mechanism, wherein lower link
It is connected to the side of double-screw type melting extruder.
Preferably, the upper connecting rod is made up of side by side many connecting rods, constituted between adjacent connecting rod for connecting
The seam of exhaust hood afterwards.
Preferably, being to be slidably connected between the support and double-screw type melting extruder.
Preferably, the outside of the rear exhaust hood is in umbrella-shaped structure.
Compared with prior art, usefulness of the present utility model is：This double-screw type melting extruder exhaust system
It is simple in construction, on the one hand the carbon brush powder in direct current generator can be suctioned out working region, it is ensured that product quality, another aspect energy
It is enough to discharge the pernicious gas discharged at discharging opening mould, it is ensured that workshop air is not easily susceptible to pollution, it is ensured that work people
The health of member.

Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in detail embodiment：
A kind of double-screw type melting extruder exhaust system shown in Fig. 1 and Fig. 2, with preceding exhaust hood 1 and rear exhaust hood 2；
The preceding exhaust hood 1 is arranged on the direct current generator 6 of double-screw type melting extruder 5, and the rear exhaust hood 2 is arranged on twin-screw
The top of discharging opening mould 7 of formula melting extruder 5, its top is connected with delivery pipe 3, for convenience will be from the row of discharging opening mould 7
The pernicious gas gone out is fully discharged, and the outside of the rear exhaust hood 2 is in umbrella-shaped structure, and Open Side Down for it；The rear exhaust hood 2 with
Connected between double-screw type melting extruder 5 by support 4.
Rear exhaust hood 2 is connected on support 4 for convenience, the support 4 is made up of upper connecting rod and lower link, its side
In " T " font mechanism, wherein lower link is connected to the side of double-screw type melting extruder 5, between to be slidably connected；On described
Connecting rod is made up of side by side many connecting rods, and the seam 8 for exhaust hood after connection 2, heel row are constituted between adjacent connecting rod
On a top seam 8 installed therein for fan housing 2, between be bolted.
This double-screw type melting extruder exhaust system is simple in construction, on the one hand can be by the carbon brush in direct current generator 6
Powder suctions out working region, it is ensured that product quality, on the other hand can arrange the pernicious gas discharged at discharging opening mould 7
Go out, it is ensured that workshop air is not easily susceptible to pollution, it is ensured that the health of staff.
It is emphasized that：It the above is only preferred embodiment of the present utility model, not the utility model appointed
What formal limitation, every any simple modification made according to technical spirit of the present utility model to above example, etc.
With change and modification, in the range of still falling within technical solutions of the utility model.
