Welding workshop dust lose ash discharging equipment classification welding workshop dust ash discharging device is divided into two categories, ash discharge and ash conveying equipment.
Ash discharge equipment mainly discharge valve, the ash can be classified by way of subordinates.
According to the ash conveying equipment of the power, can be divided into mechanical transmission device and pneumatic conveying device.
According to the ash conveying equipment performance, can be divided into: a.
Downward transmission, such as discharge device;
b。
Horizontal transmission, such as scraper conveyor, belt conveyor, screw conveyor;
C。
Upward transportation, such as bucket elevator.
According to the conveying water, whether can be divided into dry type conveyer and wet type conveyer.
Welding workshop working principle of the dust ash discharging device of the lose of the welding workshop dust removing all the dust ash hopper respectively after the first discharge valve on the scraper conveyor, if there are two ash discharging hopper by two deputy conveyor to cut out a set pair on the conveyor, and the discharge to the lower part of bucket elevator.
Dust discharge after the elevator up to a certain height to ash storage tank.
The dust ash storage tank full (
About 4/5 of grey tank height)
After time away from dust collection vehicles, no dust collection vehicles, can be directly by the ash cans of unloaded the dust by the discharge valve, dust on the car away.
In order to avoid dust available humidifying machine unloaded the dust again after spray dust on the car.
For small dust, ash discharging device is simple.
Ash discharge with a discharge valve, the ash to send grey car directly with screw conveyor, the timing of grey car away.
Also some small dust catcher the ash into the pit, to clean up regularly.
This method than the ash into the car in the complex operation, may cause secondary pollution of dust.
In addition to the mechanical transmission, pneumatic conveying system is the common way that ash.
Their motivation is high pressure fan to attract strong airflow.
Is the main equipment of discharge valve, pneumatic conveying pipeline, the ash cans and gas-solid separation device and high-pressure induced draft fan, etc.
