Abstract
The utility model discloses a gravitational discharge type bucket elevator. The gravitational discharge type bucket elevator comprises a motor, a shell, a dragging shaft which is arranged on the shell and is driven by the motor, dragging chain wheels which are arranged on the dragging shaft, elevating chains driven by the dragging chain wheels, a plurality of circular bottom material conveying hoppers which are arranged on the elevating chains, a material inlet hopper which is arranged below the shell, and a central discharge hopper which is arranged on the upper part of the shell and is provided with a discharge chute. The gravitational discharge type bucket elevator is low in running speed and long in service life, and can be widely applied to a deslagging system of a coal-fired boiler; and back flow can be avoided during central discharge.
Description
Technical field the present invention relates to a kind of gravity dumping type bucket elevator, can be widely used in coal burning boiler and remove in the slag system.
The background technology bucket elevator is the lifting means of a kind of vertical transport powdery, granular and little lump material, is most widely used a kind of vertical-lift equipment.At present, the domestic bucket elevator that generally uses is a side charging, the opposite side discharging; Its inlet point, discharge port but can't be avoided the feed back problem, the bottom buildup problem that feed back causes during discharging fully in same plane; Hopper has increased the wearing and tearing of material to hopper when drawing material, consumed power increases simultaneously, has reduced the transport efficiency of equipment; Cause bottom accumulated slag, putty when serious, cause breakdown of equipment.
For addressing the above problem, adopt the high chain speed of chain speed 1.0～1.25m/s in early days, realize centrifugal impelling discharging, although can solve the feed back problem preferably, the high speed chain causes chain, sprocket wheel serious wear, and equipment dependability is low, and the long-term use life-span is low.In recent years, in order to solve chain, sprocket wheel serious wear problem, reduce chain speed, adopt the combination form of centrifugal material casting and gravity dumping, making discharging is the discharging of gravity induction type.But running velocity is low more, and feed back is serious more, no matter slag input amount what, all must guarantee under the certain speed state not putty of operation, reduce feed back and still can't thoroughly solve this difficult problem of feed back although increase hyoplastron at discharge port.And still higher because of running velocity, its running gear life-span and reliability aspect can not guarantee the basic demand of the continuous failure-free operation of bucket elevator more than 1 year.The bucket elevator of this pattern is main with the heavily loaded chain bucket hoist of side charging, side discharging pattern; It is widely used in coal, chemical industry, thermoelectricity, cement industry and grain storage and transportation field, but operation life is low, the problem of poor reliability except that still exposing in the slag system at the continuous coal burning boiler that moves of needs.At present, become coal-fired power station boiler and removed slag system continuously during the wet lime-ash in one of the weak link of safe operation, especially vertical transport coal-burning power plant, had that buck refluxes, material stickingly struggles against, the discharging difficult problem.
The gravity dumping type bucket elevator that summary of the invention the object of the present invention is to provide that a kind of running velocity is low, long service life, center discharging do not have backflow.
In order to achieve the above object, gravity dumping type bucket elevator of the present invention comprises motor; Casing is installed on the casing and by the motor-driven axle that drags, is installed in the sprocket wheel that drags that drags on the axle; By the lifting chain that drags chain wheel drive; Be installed in several circular arc substrate material conveyor hoppers that promote on the chain, be installed in the feeder hopper of casing below, be installed in the casing top and have the center discharge hopper of discharge chute.
Gravity dumping type bucket elevator of the present invention, said center discharge hopper to greatest extent near circular arc substrate material conveyor hopper, but does not allow to contact circular arc substrate material conveyor hopper.
Gravity dumping type bucket elevator of the present invention, material is inner by several circular arc substrate material conveyor hoppers of the inlet point inflow solid matter of feeder hopper, and motor-driven drags axle; Dragging axle drives and drags sprocket wheel; Drag chain wheel drive and promote chain, promote hopper that chain will be loaded with material and rise to top and drag sprocket wheel, when circular arc substrate material conveyor hopper is crossed counter-rotating discharging when dragging sprocket wheel; Material falls in the discharge hopper of center by gravity, by discharge chute material is laid down.
Gravity dumping type bucket elevator of the present invention, discharge way are that material does not have the discharging of backflow center, can realize low-speed running, improve transport efficiency greatly, improve service life of equipment.
In sum, gravity dumping type bucket elevator of the present invention, running velocity is low, long service life, the center discharging does not have backflow.
Description of drawings is done explanation further below in conjunction with accompanying drawing and embodiment to the present invention.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view among Fig. 1.
The specific embodiment is in Fig. 1, Fig. 2, and gravity dumping type bucket elevator of the present invention comprises motor 1; Casing 2 is installed on the casing and by the motor-driven axle 3 that drags, and is installed in to drag to drag sprocket wheel 4 on the axle; By the lifting chain 5 that drags chain wheel drive; Be installed in several circular arc substrate material conveyor hoppers 6 that promote on the chain, be installed in the feeder hopper 7 of casing below, be installed in the casing top and have the center discharge hopper 8 of discharge chute.
In addition, among the figure, inlet point a, discharge port b.
Gravity dumping type bucket elevator of the present invention feed back occurs for preventing gravity dumping, and material is in the discharging of bucket elevator center, and Fig. 1 right-of-center in political views's side chain bar up moves, and drives circular arc substrate material conveyor hopper and promotes, and the left side chain is the unloaded chain of backhaul.
Gravity dumping type bucket elevator of the present invention, said circular arc substrate material conveyor hopper, sprocket wheel shown in Figure 1 is a left-hand revolution; When hopper be promoted to drag position, 0 ° of angle, wheel center after; Chain, hopper begin with dragging sprocket wheel rotation, during 20～30 ° of hopper rotations, begin discharging when taking over the hopper position in promptly; When hopper rotates 120 °, but the hopper position discharging of taking back promptly finishes.
