Abstract
The utility model discloses a dust removal device for automatically controlling ash transportation. The dust removal device (1) comprises an ash discharging bin (2) and an ash discharging pipe (9), wherein an ash discharging valve (3) is arranged on the ash discharging pipe (9); and the ash discharging bin (2) is provided with a material level detecting device which is electrically connected the ash discharging valve (3) by an automatic control device (10). According to the dust removal device for automatically controlling the ash transportation, the material level detecting device is arranged, so that automation detection of the amount of ash in the ash discharging bin, as well as the automatic control on ash discharging can be realized; when the accumulated ash in the ash discharging bin reaches the upper limit on detection, the ash discharging valve can be automatically turned on to discharge the ash by the automatic control device; and when the ash is discharged to reach the lower limit on detection, the ash discharging valve and an air supply device can be automatically controlled by the automatic control device, so that the automatic control on the ash transportation operation can be realized. The dust removal device is simple in structure and stable and reliable in work; the ash can be ensured to be timely removed, and proper lower limit on the amount of the stored ash can be able to be reserved, so that the diffusive air leakage can be prevented, as a result, the accident due to safety can be effectively avoided.
Description
Technical field
The utility model belongs to the coal gas dust removal equipment technical field, is specifically related to a kind of simple in structurely, and working stability is reliable, can accurately detect and accumulate the ash amount, in time clears up and keep the cleaning apparatus of the defeated ash of automatic control of suitable surplus.
Background technology
One of most important corollary system of steel-making blast furnace is exactly coal gas dust collector.Such as, 2500m
3The dry type gas dust removal system that blast furnace is supporting can be furnished with 14 cleaning apparatuss and two ash-storing bins usually.The appearance ash amount of cleaning apparatus is certain, needs in time to remove, otherwise will affect production.If take manual detection ash amount, manually boot the deashing operation, need to expend larger manually, be also disadvantageous for automatic production.Prior art adopts regularly defeated grey mode usually, i.e. unification sets the time, no matter the ash amount of the appearance ash silo in cleaning apparatus all can be carried out defeated ash manipulation on time, can cause unnecessary waste like this.And defeated ash manipulation too frequently also can affect to cleaning apparatus, even damages, and pipeline occurs and leaks ash.If the defeated ash of cleaning apparatus is excessive, ash silo is diffused and the unsafe problems such as is caused coal gas to exceed standard can to set off an explosion.For this reason, develop a kind of simple in structurely, working stability is reliable, and ash is full namely clear, and the cleaning apparatus of the defeated ash of automatic control that do not leak of not overflowing is very important.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and working stability is reliable, can accurately detect and accumulate the ash amount, in time clears up and keep the cleaning apparatus of the defeated ash of automatic control of suitable surplus.
