Abstract
A negative pressure automatic ash discharging device. The device is characterized in that a valve plate and a valve plate are arranged in a valve seat of an ash discharging rectangular guide pipe, and the included angle between the valve plate and the valve seat is 25-75 degrees. Under the gravity action of falling dust, the valve plate is opened to discharge the dust; reset under the suction of negative pressure, and automatically complete the ash discharging function. The device is suitable for discharging ash of pulse, multi-tube and electrostatic dust collectors, is particularly suitable for discharging ash of mechanical rapping type bag dust collectors, and has the advantages of investment saving, convenient maintenance and reliable work.
Description
The utility model is applicable to pulse, multitube and electrostatic precipitator ash discharge, is specially adapted to the ash that unloads of mechanical vibrator formula sack cleaner.
Cleaner captures the dust that gets off, all temporarily is stored in the ash bucket of dust exhaust apparatus, is discharged discontinuously by the ash-discharging device of ash bucket bottom then.The simplest ash-discharging device is to use manually-operated sluice valve.
In industrial production, the existing the most frequently used ash-discharging device of cleaner is rotating segment feeder (being star-shaped ash unloading valve), and it is made up of impeller, shell, sprocket wheel, chain and motor.Impeller and shell form simple seal, and can make of various materials.The number of teeth of adjusting driving wheel and follower can be controlled one and suitable unload grey speed.Dust just can be interrupted discharge when motor started.
The main weak point of prior art: 1. stop up easily in the use, two weeks will be cleared up maintenance once.Complex structure, need power, take up room greatly, it is many to spend.
The present invention utilizes that negative pressure changes existing ash-discharging device into the negative pressure automatic ash-discharging device in the dust catcher chamber, can overcome above-mentioned shortcoming.Concrete way is to make existing unloading valve shell into the rectangular conduit valve seat to adorn a valve plate and valve block at valve seat.Valve seat top is connected with storage hopper, the bottom with unload grey comb and be connected, the dust that deduster is collected constantly falls in the rectangular conduit valve seat, valve is opened when the torque that weight produces of dust forms torque greater than negative pressure, dust falls in the Pei Liao Warehouse, and this moment, valve block can reset 1 second under the atmospheric pressure effect.According to the draft of blower fan and the size of valve block, unload ash for twice and can be controlled within 5～20 minutes blanking time.
Accompanying drawing is represented the structure of ash-discharging device.
The 1-valve seat, 2-valve plate, 3-hinge, 4-valve block.
Weldering one metal foil (valve plate) in the valve seat of rectangular conduit forms 25 °～75 ° angles with valve seat, digs a rectangular opening in the middle and lower part of metal foil (valve plate), a face down bonding hinge and be connected with valve block below rectangular opening.This device only is welded with little block plate, 5～10 kilograms of weight.
Service time, reliable always, Maintenance and Repair made things convenient for this device all above 3 years continuously in 72 bags of certain refractory factory and 108 bags of mechanical vibrator dedusters.(seeing attached list)
