Description
Technical field
The utility model belongs to iron and steel metallurgical industry field, is specifically related to a kind of dust exhaustor ash silo to a kind of dedusting lifting cover controlling reentrainment of dust when drawing grey car to put ash.
Background technology
A large amount of dusts that iron and steel metallurgical industry produces in process of production, first by dust exhaustor by dust arrestment in the ash silo of dedusting, then by the ash-valve periodic exhaustion of ash silo bottom in the ash bucket of transport automobile.Producing reentrainment of dust when unloading ash in order to prevent ash silo to automobile, being provided with damping device at ash silo cinder-discharging port place and wet treatment is added to dust, basic controlling reentrainment of dust, but still cannot thoroughly control.At present, the measure controlling further reentrainment of dust between the ash discharging hole and automobile ash bucket of humidifier, installs easy soft cloth bag carry out closing to a certain degree, and the poor effect closed on the one hand, reentrainment of dust is not collected on the other hand, and effect is undesirable.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of height adjustable, ash-removing mouth and automobile ash bucket effectively can be closed, and again traps reentrainment of dust, effectively controls the excessive dedusting lifting cover of reentrainment of dust.
For achieving the above object, the technical solution adopted in the utility model is: a kind of dedusting lifting cover, comprise fixing taper ash cover, flexible taper ash cover and lift system, described fixing taper ash cover top is furnished with upper flange, this upper flange and ash-removing mouth flange match, fixing taper ash cover bottom is furnished with lower flange, and the top flange that this lower flange and flexible taper ash cover top is matched, and the conical section position of fixing taper ash cover is provided with the negative-pressure pipeline be connected with dust exhaustor.
Further, described flexible taper ash cover comprises bottom fixing collar, middle fixing collar, top flange, hanger and dust-proof soft cloth, and described bottom fixing collar is connected with middle fixing collar by dust-proof soft cloth, and middle fixing collar is connected with top flange by dust-proof soft cloth.
Further, the quantity of described middle fixing collar is at least 2.
Further, the external diameter of described middle fixing collar is greater than the internal diameter of described bottom fixing collar.
Further, described bottom fixing collar is provided with the uniform hanger of 3 circumferences.
Further, described lift system comprises electronic elevator, steel rope and track adjusting wheel, and described steel rope one end is fixed on the hanger of flexible taper ash cover, and the other end is connected with the reel of electronic elevator, and centre is provided with track adjusting wheel, plays the object changing steel rope direction.Wherein, the number of described track adjusting wheel has 4, and a reel of electronic elevator is furnished with 3 steel ropes.
Further, described negative-pressure pipeline is provided with valve.
When reel rotates clockwise, on it 3 steel ropes are driven to be wound around around reel, steel rope drives the bottom fixing collar upward movement of retractable cone shape ash cover, after bottom fixing collar is moved upwards up to certain position, in the middle of bottom fixing collar just holds up, fixing collar moves up, after middle fixing collar is moved upwards up to certain position, middle fixing collar just holds up a middle fixing collar and moves up, and whole like this telescopic cover shortens successively.When electric reel rotates counterclockwise, whole flexible taper is looked for and being moved downward under gravity, and last whole telescopic cover launches in a cone-shaped hood.
When putting ash, the height of whole telescopic cover can adjust according to the height filling grey automobile ash bucket, guarantee to put the space forming a relative closure in grey process between grey mouth and automobile ash bucket, open the valve on the negative-pressure pipeline of fixing taper ash cover simultaneously, keep negative pressure certain in whole telescopic cover, thus reach the object without airborne dust.After discharging ash, whole telescopic cover retraction, thus form minimum space, close the valve on the negative-pressure pipeline of fixing taper ash cover.
The beneficial effects of the utility model are:
1, due to be provided with flexible taper ash cover, when not using, whole telescopic cover can bounce back, make compact conformation, take up room little, simple to operation;
2, putting in grey process, lift system according to the differing heights adjustment dust excluding hood drawing grey compartment, can be guaranteed that dust excluding hood and ash-removing mouth form a closed space, effectively can control, collect reentrainment of dust;
3, the interface of whole telescopic cover top and dust exhaustor can be guaranteed to keep certain negative pressure in the space closed, is again collected in dust exhaustor by reentrainment of dust, ensure that when putting ash without reentrainment of dust.
