Description
Technical field
It the utility model is related to a kind of waste gas collection device, and in particular to one kind is used to produce twin-screw extrusion machine inlet
Raw waste gas carries out the balanced type exhaust gas absorption device of suction.
Background technology
Double screw extruder, it is a kind of conventional modifying plastics equipment, in actual production, due to double screw extruder
Charging aperture is unenclosed construction, when base-material and modifying agent enter heated in fuselage, can decompose generation waste gas, while base-material and modification
Agent can also produce certain steam when heated, and the smog that waste gas and steam are mixed to form can emerge from charging aperture enters production car
Between, production environment is greatly affected, while production environment can also be polluted, it can further influence the people that worked in workshop
The health of member.
Traditional way be by the waste gas purification apparatus on production environment periphery by outside the exhaust removal chamber in workshop, but its
Supporting extraction duct and device it is complicated, space-consuming is big, and waste gas absorption power consumption is big (to need the air progress to whole workshop
Discharge), and the waste gas for spreading in workshop can not thoroughly solve this problem because air flow tends not to be sucked away completely.
It is exactly one discharge duct of increase on charging aperture to also have a kind of way in addition, by aspirating pumping waste gas, this
Although kind of a method can prevent waste gas from spilling into workshop, when aspirating waste gas, have a small amount of material and inhaled with waste gas
Upper discharge duct is simultaneously discharged, and causes material waste, while discharge duct may interfere with the blanking feelings that staff observes charging aperture
Condition, production process is adversely affected.
Utility model content
The defects of the purpose of this utility model is to overcome prior art, there is provided one kind is used for twin-screw extrusion machine inlet
The balanced type exhaust gas absorption device of waste gas absorption, its is simple in construction, can be achieved to be collected the waste gas that charging aperture is emerged and defeated
The off-gas cleaning equipment in downstream is sent to, improves the working environment of workshop, reduces body of the waste gas to staff in workshop
Health impacts.
To realize object above, the utility model adopts the technical scheme that：
A kind of balanced type exhaust gas absorption device, for being absorbed to waste gas caused by twin-screw extrusion machine inlet, bag
The balance bunker for collecting waste gas is included, exhaust gas entrance is provided with balance bunker side bottom surface, on the top of balance bunker face exhaust gas entrance
Face is provided with air intake, and pump drainage blower fan, the exhaust gas entrance installation are provided with opposite side top surface of the balance bunker away from air intake
In the charging aperture of double screw extruder, the outlet of the pump drainage blower fan is connected by pipeline with the off-gas cleaning equipment in downstream.
Further, the pressure inside balance bunker is controlled for convenience, is additionally provided with the air intake for adjusting it
The opening adjusting device of openings of sizes.
Further, in order that waste gas is preferably concentrated in the balance bunker of pump drainage blower fan side, the balance bunker is rank
Ladder type structure, it is provided with the height of pump drainage blower fan side and is more than the height provided with exhaust gas entrance side.
Balanced type exhaust gas absorption device of the present utility model, balance bunker is used to collect the waste gas that charging aperture emits, empty
The pressure that gas entrance is used in adjustment storehouse, pump drainage blower fan are used for the waste gas purification that the waste gas in balance bunker is drained into downstream
Equipment, prevent waste gas from being overflowed from air intake.
With prior art ratio, the utility model has advantages below：
1st, pump drainage blower fan and twin-screw extrusion machine inlet stagger setting, effectively avoid material from being sucked up balance with waste gas
Storehouse, loss of material will not be caused.
2nd, air intake is used for the air flow for strengthening balance bunker, improves waste gas expulsion efficiency；Staff goes back simultaneously
The putting material situation of charging aperture can be observed by air intake, ensures being smoothed out for production.
3rd, the pressure that opening adjusting device is used in adjustment storehouse, according to production status, the operating of pump drainage blower fan is adjusted
Speed, reduce energy consumption.
4th, it is simple in construction, install and easy to operate, occupy little space, there is obvious economic benefit and social benefit.
Brief description of the drawings
Fig. 1 is that the structure of the utility model balanced type exhaust gas absorption device is intended to；；
Description of reference numerals：1- balance bunkers, 2- exhaust gas entrances, 3- air intakes, 4- pump drainages blower fan, 5- opening regulation dresses
Put.
Embodiment
Content of the present utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment：
It refer to shown in Fig. 1, a kind of balanced type exhaust gas absorption device, for being given up caused by twin-screw extrusion machine inlet
Gas is absorbed, including for collecting the balance bunker 1 of waste gas, exhaust gas entrance 2 is provided with the side bottom surface of balance bunker 1, in balance bunker 1
The top surface of face exhaust gas entrance 2 is provided with air intake 3, and pump drainage wind is provided with opposite side top surface of the balance bunker 1 away from air intake 3
Machine 4.1 preferred stepped construction of balance bunker, the height for being provided with the side of pump drainage blower fan 4 are more than and open up exhaust gas entrance 2 and air enters
The height of mouth side, it is easy to waste gas to concentrate in the balance bunker of the side of installation pump drainage blower fan 4.It is additionally provided with air intake 3
For adjusting the opening adjusting device 5 of its openings of sizes, the concrete structure of opening adjusting device 5 can use conventional technique,
