Description

Ash ejector before a kind of boiler

Technical field:

The utility model relates to the ash discharge technical field of Industrial Boiler, is the deashing device of using before a kind of boiler specifically.

Background technology:

Coal grain and coal ash that the fire grate of existing coal-burning boiler is in operation and can leaks down inevitably and partly not burn, the particle of this part coal ash is thinner, and is very dry, temperature is not high yet, the ash discharge amount that needs is also little, but it is removed because equipment, and the ash discharge effect is unsatisfactory; Boiler for bilayer is arranged can be dumped directly into one deck to ash and transport the way that the waterpower deashing was transported or adopted to grey dolly; Boiler for the individual layer layout, the removing of this part coal ash is just relatively more difficult, artificial deashing at present commonly used, coal ash in fire grate sprays running water at first earlier, opening the fire grate shroud upper panel then claws it, and the grey dolly of fortune of packing into, when the fire grate front end is equipped with coaling machine, just need on the coal bunker hole of coaling machine, to lay platform earlier, people then could stand, finish the ash discharge process, also some producer changes into the side that boiler does not have fire grate transmission reduction box to the ash hole of boiler front end, by the side ash discharge for fear of the influence of coaling machine to ash discharge, but because fire grate broad, some fireman only removes the ashes near ash hole, often can not full scale clearance near inboard coal ash, because the accumulating of coal ash, usually can influence the fire grate operation, cause the fire grate segment at this place to rupture easily; There is this boiler producer to design some simple spiral ash ejectors, do not reach the purpose of deashing, often block, cause the motor overload of spiral ash ejector and burn motor, thereby a kind of ash-removal effect is good, equipment attrition is light, ash ejector safe and reliable to operation, easy to maintenance, long service life was not seen at present.

Summary of the invention:

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and provide that a kind of ash-removal effect is good, equipment attrition is light, the ash ejector of safe and reliable to operation, easy to maintenance, long service life, mainly solved a large amount of ashes is piled up ash ejector asphyxia by external pressure on the chest and abdomen, serious, the thin ash of bearing wear toward two side bearing places problem.

In order to achieve the above object, the utility model is achieved in that the preceding ash ejector of a kind of boiler, it comprises the reductor 13 that connects motor, right bearing 11, left bearing 1, ash ejector seat 6, supporting plate 14, a left side, right bearing 1, establish lubricating cup 2 on 11 respectively, left bearing 1 is connected with left side axle 4, between establish sealing ring 3, right bearing 11 is connected with right axle 9, between establish sealing ring 3, establish steel pipe 7 at left side axle 4 and 9 on right axle, its special character is to establish flight 8 on the described steel pipe 7, and flight 8 is for equidistant, near establishing the flight 5 reverse with flight 8 on the steel pipe 7 of ash hole one end.

To achieve these goals, ash ejector before a kind of boiler of the present utility model, its described steel pipe 7 is established rotation dust remover 10 near an end of motor; Establish radial thrust bearing 12 in the described right bearing 11; Described supporting plate 14 has angle.

Ash ejector before a kind of boiler described in the utility model, compared with the prior art, have following good effect: what 1, the flight of existing ash ejector adopted is the flight of uniform pitch, when thin ash is promoted toward opposite side by a side, can increase gradually, and the pitch of flight is constant, therefore through regular meeting the situation of a large amount of ashes with the ash ejector asphyxia by external pressure on the chest and abdomen appears, and the utility model is owing to adopted the flight of decreasing worm-pitch, pitch along the thin grey direction flight that promotes increases gradually, has solved the problem of a large amount of ashes with the ash ejector asphyxia by external pressure on the chest and abdomen; During 2, owing to ash ejector work, can give the very big opposition of bearing near motor side, make this bearing wear serious, cause motor overload, accident often occur, the utility model is being installed radial thrust bearing near in the bearing of motor side; 3, for preventing that thin ash is deposited in two side bearing places and enters in the bearing, this ash ejector has been installed the flight reverse with pushing away grey flight near motor side the rotation dust remover being installed at opposite side, thereby has solved the problem that thin ash is piled up toward two side bearing places; 4, safe and reliable to operation, easy to maintenance, long service life.

Description of drawings:

Fig. 1---structural representation of the present utility model;

The A-A cut-away view of Fig. 2---Fig. 1.

The specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe ash ejector before a kind of boiler of the utility model in detail.

Embodiment, referring to Fig. 1,2, on left bearing 1 that processes and right bearing 11, lubricating cup 2 is installed respectively, left bearing 1 is fixedlyed connected with left side axle 4, between with sealing ring 3 sealing, right bearing 11 is fixedlyed connected with right axle 9, between with sealing ring 3 sealing, at left side axle 4 and 9 socket steel pipes 7 of right axle, welding flight 8 on steel pipe 7, flight 8 is not for equidistant, be generally four kinds of pitch, promptly the pitch of the direction flight that promotes along thin ash increases gradually, near the reverse flight 5 of welding on the steel pipe 7 of ash hole one end and flight 8, fixedly mounts ash ejector seat 6 outside the flight of ash hole one end; Right bearing 11 is fixed together with the reductor 13 that is connected motor, establish supporting plate 14 in the outside of flight 8, supporting plate 14 has angle, translator one end is installed in the fire grate wallboard, at last ash ejector seat 6 usefulness bolting are installed on the fire grate wallboard, as long as ash ejector seat 6 and fire grate wallboard connecting bolt are turned on, ash ejector can be hauled out from the fire grate bottom, keep in repair very convenient.

Ash ejector before a kind of boiler of the present utility model is installed rotation dust remover 10 on the steel pipe 7 near an end of motor; Radial thrust bearing 12 is installed in above-mentioned right bearing 11.

When ash ejector is worked before a kind of boiler of the present utility model, the ash ejector motor via reducer drives the not equidistant flight rotation that is welded on the steel pipe, the coal ash of fire grate bottom is promoted toward ash hole by close motor side, fall into the ashpit of fire grate outside at last by ash hole, finish the purpose of fire grate deashing, be provided with the rotation dust remover near motor side simultaneously, prevent that thin ash from entering bearing; Designed the flight reverse with pushing away grey flight near the ash discharge oral-lateral, the thin dust heap mass in the left bearing side in order to prevent to release with damage of bearings, has guaranteed the normal operation of boiler.
