Abstract

The utility model relates to a fork-type cinder heavy-duty chain conveyer which is used for a large-scale industrial boiler to discharge slag. The conveyer is provided with an ash groove in which a warped-wing type chains is arranged. The ash groove of the conveyer has a section of oblique ascension, and the beginning point of the oblique ascension is provided with a pressure roller. The chains of the conveyer are provided with a crocodile fork in front of the warped-wing. With simple structure, the utility model can uplift the ash to 7-8 meters in short distance with no large size cinder falling down for gravity with a high efficiency of slagging. Furthermore, the conveyer has reliable working and low failure rate, which is convenient to be installed and repaired and the regular running of the boiler can be ensured.

Description

Fork-type cinder heavy-duty chain conveyer

The utility model relates to a kind of boiler deslagging device, particularly a kind of V shape heavy chain bar slag conveyer.

Existing multiple heavy chain slag remover in the prior art, this chain is the cast iron manufacturing, and the fork pin both sides of chain are provided with the outside wing that sticks up, and chain is dragged by sprocket wheel in clinker groove, can disintegrating slag, and the lime-ash of Industrial Boiler is got rid of.But slag remover in the past uses and still is apparent not enough (as at every evaporation capacity during as 12 boilers production run simultaneously more than the 35t/h) in more large-scale boiler room, often still need with traditional Martin's formula slag crusher disintegrating slag of going ahead of the rest, and then water pours slag in the slag bath, thereby producing cost height, workman's condition of work is abominable, and inconvenient maintenance influences ordinary production easily.Existing in addition heavy chain slag remover also has a shortcoming, and promptly its clinker groove is a level, is unsuitable for the direct entrucking requirements on transport of lime-ash in large-sized boiler room.

The purpose of this utility model provides a kind of be fit to transport a large amount of lime-ash and bulk lime-ash, and lime-ash can be risen to the V shape heavy chain bar slag product conveyor of 7～8 meters above positions of height, to overcome weak point of the prior art.

The purpose of this utility model is to realize like this.

V shape heavy chain bar slag conveyer comprises clinker groove 6, warped fin type chain 4, carrying roller 5 and driving wheel 1 and driven pulley 2.The clinker groove of conveyer connects one section skewed slot by 20～45 ° of lift angles by one section level trough and forms.Above the starting point of skewed slot, be hinged with a pressure roller 3 by the sealing axle bed 7 that is connected with cell wall.The chain of conveyer is fixed with a row or multi-row wing 11 that sticks up in the outside of its two forks pin 12, sticks up the parallel crocodile mouth type intersection that is provided with one or more along its horizontal center line symmetry in the place ahead of the wing.

Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.

Fig. 5 single-blade frame reinforcement prong chain link schematic diagram;

The pressure roller 3 of conveyer is the stairstepping of middle part protuberance.The width of its working face is greater than the A/F of chain fork pin 2.Working face is apart from the height of the clinker groove 6 bottoms thickness greater than chain.

Conveyer is in pressure roller the place ahead of sending into direction of chain, with the cell wall tripper 8 that to be connected with its "T"-shaped front be dihedral.

The inner face of the crocodile mouth type intersection 13 on the conveyor chain, can be the fork two inwalls intersect at the prong root "＜" shape, also can be the fork two inwalls respectively with the upper and lower " (" shape that links to each other in the vertical plane of prong root.

Conveyor chain is fixed with reinforcement at the back side of sticking up the wing.It can have flat reinforcement 14; Frame reinforcement 15 can be arranged; Also folded plate type reinforcement 16 can be arranged.The form of reinforcement can make up arbitrarily as required.

The utility model conveyer is directly installed under one of boiler room or several the boilers in use, and the lime-ash of whereabouts just sends out at any time, establishes a lime-ash tower at the upper outlet place of clinker groove, just can deposit lime-ash, and can directly unload and be contained in the wagon box.Tripper 8 is set before pressure roller can pushes lime-ash or the hard foreign matter of dirt to both sides, and avoid pressure roller to be stuck.Simultaneously tripper also can be installed in play a part before the driving wheel same.Prong on the chain can " be stung the big clinker in the lime-ash " and live to carry, tumbles in the process of avoiding clinker on being tilted to, to carry, thus the efficient of assurance deslagging.This conveyer is used its better effects if with fall slag plate-turning door and passive type breaker.

The utility model is simple in structure, reliable operation, and fault rate is low, can guarantee that boiler normally moves, and installation and maintenance are convenient.Be suitable on the large scale industry boiler, using.
