Abstract
A kind of sealing device for Discussion on Multi-ring Coal Feeder, the seal groove of the embedded board lower part of silo is fixed on including circumferential direction, the edge of one side opening of seal groove, rotation car body coal bearing disk is extend into inside seal groove by the opening of seal groove, 3 inside filling flexible material of seal groove.The utility model has the beneficial effects that will not only generate resistance to rotation car body coal bearing disk, but also flexible material is effectively prevented from coal dust spilling when rotation car body coal bearing disk is contacted and done relative motion with flexible material.It is ensured that required sealing effect.
Description
Technical field
The utility model relates to a kind of sealing devices, concretely relate to one kind and do for Discussion on Multi-ring Coal Feeder with seal closure
When relative motion, the sealing device for preventing leakage of pulverized coal is played by flexible material.
Background technique
As China's electric power, coal, coal chemical industry cause are constantly progressive, the need of domestic and international fired power generating unit and coal chemical industry to coal
The amount of asking is increasing, and the storing mode of various coals comes into being, and silo has many advantages, such as that Economization on land, environmental protection, coal storage are big
It is widely adopted.Discussion on Multi-ring Coal Feeder is matched with raw coal silo, can solve silo chute blockage, coal blending problem, while saving and accounting for
Ground reduces environmental pollution, and is ideal equipment in Coal Transportation System.
Discussion on Multi-ring Coal Feeder mainly by driving device, electric-control system, plough coal car, unload coal car, coal plough, horizontal location wheel, row
The composition such as pulley device, sealing device.It ploughs coal car and unloads coal car and dragged by motor reducer, the two vehicle speeds of service are different, side
To opposite.When plough coal car operating when, positioned at silo bottom coal plough coal from silo ring type gap plough under, fall on and run
Unload on coal car, until falling on lower layer's belt conveyor.However, unloading the coal on coal car with the increase for car body revolving speed of unloading coal
Also progressive additive will cause to unload coal car coal bearing disk edge leakage coal under the influence of centrifugal force.The spilling of coal dust not only causes whole
A silo environment pollution, and greatly threaten the health of operator.Therefore, for this problem, conventional method
Be seal closure inner or outer side or simultaneously install rubber slab additional inside and outside, contact and do opposite with coal car coal bearing disk is unloaded
Movement still still has coal dust spilling after taking these methods.
Utility model content
The purpose of this utility model is to provide a kind of sealing device, coal car carrousel body coal bearing disk and seal closure are unloaded in guarantee
Relative motion while, by avoiding coal dust from overflowing using a kind of flexible material, it is ensured that the sealing effect of silo.
The utility model uses following technical scheme:
A kind of sealing device for Discussion on Multi-ring Coal Feeder is fixed on the seal groove of 8 lower part of embedded board of silo including circumferential direction
3, the edge of 3 one side opening of seal groove, rotation car body coal bearing disk 5 is extend into seal groove 3 by the opening of seal groove 3
Portion, 3 inside filling flexible material 4 of seal groove.
The fore-and-aft distance of 3 opening of seal groove is not more than the fore-and-aft distance of 3 inner space of seal groove.
The seal groove 3 is fixed on sealing plate 2, and sealing plate 2 is fixed on the fixed bracket 1 of sealing plate, and sealing plate is fixed
Bracket 1 is fixed on embedded board 8.
The utility model has the beneficial effects that when rotation car body coal bearing disk is contacted and done relative motion with flexible material,
Resistance will not be not only generated to rotation car body coal bearing disk, but also flexible material is effectively prevented from coal dust spilling.It is ensured that institute
It is required that sealing effect.
Detailed description of the invention
Fig. 1 is the utility model structural section schematic diagram.
Fig. 2 is the utility model use state diagram.
Wherein, 1 is the fixed bracket of sealing plate；2 be sealing plate；3 be seal groove；4 be flexible material；5 be that rotation car body is held
Coal disk；6 be silo；7 be Discussion on Multi-ring Coal Feeder；8 be embedded board；9 be sealing device.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The utility model provides a kind of sealing device for Discussion on Multi-ring Coal Feeder, guarantee unload coal car carrousel body coal bearing disk and
While the relative motion of seal closure, coal dust is avoided to overflow, it is ensured that the sealing effect of silo.
The sealing structure of the utility model includes the seal groove 3 of circumferential 8 lower part of embedded board for being fixed on silo 6, seal groove 3
The edge of one side opening, rotation car body coal bearing disk 5 is extend into inside seal groove 3 by the opening of seal groove 3, is opened with seal groove 3
The opposite side of mouth does not contact, 3 inside filling flexible material 4 of seal groove, and rotation car body coal bearing disk 5 and flexible material 4 have relatively
Movement.
Existing polytetrafluoroethylene (PTFE) may be selected in above-mentioned flexible material 4.
For the effect for guaranteeing sealing, the fore-and-aft distance of 3 opening of seal groove no more than 3 inner space of seal groove it is longitudinal away from
From.As shown in Figure 1,3 section of seal groove may be selected to be the structure of triangle, it is open on an angle of triangular structure.
As depicted in figs. 1 and 2, as a kind of specific embodiment, seal groove 3 can be fixed on sealing plate 2, sealing plate
2 are fixed on the fixed bracket 1 of sealing plate, and the fixed bracket 1 of sealing plate is fixed on embedded board 8.When specific fixed, sealing plate is fixed
Bracket 1 is welded in along silo 6 fixed on the embedded board 8 of silo 6 in uniform way, and sealing plate 2 is welded in sealing plate and fixes
1 outside of bracket, ring cloth one enclose, and the uniformly distributed circle of seal groove 3 is by fillet weld seam in filling in the downside of sealing plate 2, seal groove 3
The edge of flexible material 4, the rotation car body coal bearing disk 5 to do relative motion with seal groove gos deep into seal groove, in seal groove
Flexible material contacts distance 120mm, and the inner surface for rotating seal groove 3 of 5 outermost edge of car body coal bearing disk apart from sealing device hangs down
Straight distance is 50mm.
When device as depicted in figs. 1 and 2 works:
It the plough coal car of Discussion on Multi-ring Coal Feeder 7 and unloads coal car and is dragged by motor reducer, the two vehicle speeds of service are different, direction phase
Instead.When upper layer plough coal car operating when, positioned at 6 bottom of silo coal plough coal from the ring type gap of silo 6 plough under, fall on fortune
That goes unloads on coal car carrousel body coal bearing disk 5, with the coal progressive additive on rotation car body coal bearing disk 5, in the work of centrifugal force
Under, coal dust will be stacked into 2 inner wall of sealing plate, and since sealing plate 2 is fixed on the embedded board 8 of silo 6, and seal groove 3 is fixed
In on sealing plate 2, so seal groove 3 is fixed.And rotating car body coal bearing disk 5 is made rotating motion around silo center
, so rotation car body coal bearing disk 5 and seal groove 3 do relative motion, the flexible material 4 in seal groove 3 and rotation car body
Coal bearing disk 5 contacts, and not only will not generate resistance to the rotation car body coal bearing disk 5 of rotary motion, but also due to the suction of flexible material 4
The particular groove shape of attached effect and seal groove 3 is effectively prevented from coal dust spilling.It will be played using the sealing device good close
Envelope effect, so as to avoid the working environment of silo environment pollution and improvement operator.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
