Abstract
The utility model provides a prevent activation feeder that flows automatically has the vertical barrel type to fail the workbin, the top of the defeated workbin of is the feed inlet, fails the elastic support that has gone to the bottom of workbin, and the side of defeated workbin links has electronic vibration exciter, and there is the flow distribution plate top in the defeated workbin, and there is the cam slot below of flow distribution plate, and the tank bottom of cam slot is the discharge gate, is failing difference two~six competent through -holes between the relative side of workbin discharge gate department, and the through -hole interpolation has the straight -bar. The utility model discloses two~six competent through -holes respectively between the relative side of defeated workbin discharge gate department, the through -hole interpolation has the straight -bar, can realize when electronic vibration exciter vibrate through taking and insert the straight -bar out, let granulated coal ration in the coal silo, evenly, outflow and when electronic vibration exciter stops to vibrate consecutively, pin the granulated coal at the activation feeder. The utility model discloses simple structure, the cost is lower.
Description
Technical field
This utility model relates to a kind of activation feeder, particularly a kind of anti-gravity flow pin activating feeder discharging opening。
Background technology
Activation feeder is the granular coal in coal silo in the coal handling system of thermal power plant, flows to the coal supply equipment of ribbon conveyer continuously, uniformly, quantitatively。
Activation feeder has vertical barrel type material conveying box, and the top of material conveying box is charging aperture, the flexible support of going to the bottom of material conveying box, the side of material conveying box is connected with electric activator, in material conveying box arranged above with flow distribution plate, the curved groove arranged below of flow distribution plate, the bottom land of curved groove is discharging opening。
During installation, activation feeder is arranged between coal silo and ribbon conveyer, between the charging aperture and the outlet of big moulded coal silo of activation feeder, be connected with flexibility between discharging opening and the entrance of ribbon conveyer be tightly connected shroud。
During use, material conveying box is driven to vibrate in resiliency supported with electric activator, make the more closely knit granular coal being in stacking states in material conveying box above charging aperture loosen because of vibration namely to activate, and be gradually slipped in curved groove from the flow distribution plate in material conveying box, slide into discharging opening then through curved groove to flow out, namely granular coal is the runner through flow distribution plate, curved groove and discharging opening composition, quantitatively, uniformly, be continuously delivered on ribbon conveyer。When the stopping of electric activator is vibrated, the granular coal loosened recovers more closely knit stacking states again, the physical property such as the stocking angle according to granular coal, choose the structural parameters of the runners such as the distance between suitable curved groove curvature and flow distribution plate and curved groove and discharging opening, granular coal transfixion in runner can be made, be equivalent to granular coal to pin at activation feeder, it is prevented that granular coal flows automatically to bottom belt conveyor when electric activator stops vibration through discharging opening。
In actual production process, the coal that thermal power plant uses often changes, coal handling system in running owing to being drenched with rain, Exposure to Sunlight, the water content making granular coal also changes, the physical property such as different coal, the granular coal stocking angle that water content is different are different, it is necessary to the structural parameters of activation feeder runner are also different。When the coal of granular coal and water content change, when the electric activator activating feeder stops vibration, granular coal often being occurred from flow phenomenon from discharging opening, crush belt or cause belt to rotate difficulty。
When equipment quits work, for preventing granular coal from flowing automatically from discharging opening, in prior art, the discharging opening of some activation feeder has electric expansion head, when the electric activator activating feeder stops vibration, stretches out electric expansion head, block discharging opening, it is prevented that granular coal flows automatically。
This anti-gravity flow activation feeder structure complexity at discharging opening with electric expansion head, is affected by environmental pollution, and fault is more, and cost is higher。
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is proposed to a kind of simple in construction, fault is less, the activation feeder of the anti-gravity flow that cost is relatively low。
This utility model realizes with the following method。
The activation feeder of anti-gravity flow has vertical barrel type material conveying box, the top of material conveying box is charging aperture, the flexible support of going to the bottom of material conveying box, the side of material conveying box is connected with electric activator, in material conveying box arranged above with flow distribution plate, the curved groove arranged below of flow distribution plate, the bottom land of curved groove is discharging opening, has two～six through holes that can be inserted into straight-bar of level between the side that material conveying box discharge outlet is relative respectively。
During use, activation feeder is arranged between coal silo and ribbon conveyer。
During normal operation, when driving material conveying box to vibrate in resiliency supported with electric activator, can allow runner be made up of in the granular coal normally activated feeder in coal silo flow distribution plate, curved groove and discharging opening, quantitatively, uniform, be continuously delivered on ribbon conveyer。
When coal and the water content of granular coal there occurs change, after the stopping vibration of electric activator, granular coal occurs when flow phenomenon, take a straight-bar, straight-bar is inserted in the through hole between discharge outlet opposite flank, discharge outlet in the runner being then made up of flow distribution plate, curved groove and discharging opening in activation feeder adds the straight-bar of level, change the structural parameters of runner, make granular coal transfixion in runner, granular coal is pinned at activation feeder, it is prevented that granular coal produces gravity flow when electric activator stops vibration through discharging opening。
This utility model has four through holes of level between the side that material conveying box discharge outlet is relative, straight-bar it is inserted with in through hole, when can be implemented in electric activator vibration by extracting and insert straight-bar out, allow the granular coal in coal silo quantitatively, uniformly, continuously flow out and when electric activator stops vibration, granular coal in activation feeder pinning。This utility model simple in construction, fault is less, and cost is relatively low。
Below in conjunction with accompanying drawing, the utility model is further described。
Accompanying drawing explanation
The master that Fig. 1 is the activation feeder of a kind of anti-gravity flow proposed according to scheme of the invention of the present utility model cuts open schematic diagram depending on office；
Schematic diagram cuts open in the side-looking office that Fig. 2 is Fig. 1；
Detailed description of the invention
In Fig. 1, Fig. 2, the activation feeder of anti-gravity flow has vertical barrel type material conveying box 1, the top of material conveying box is charging aperture 2, the flexible support 3 of going to the bottom of material conveying box, the side of material conveying box is connected with electric activator 4, in material conveying box arranged above with flow distribution plate 5, the curved groove arranged below 6 of flow distribution plate, the bottom land of curved groove is discharging opening 7, has level to can be inserted into four through holes 9 of straight-bar 8 between the side that material conveying box discharge outlet is relative。
