Description
Technical field
The utility model is related to cement industry feeding valve more particularly to a kind of feeding valves with preventing materials accumulation structure.
Background technology
In cement clinker production line, coal dust claims to be the important equipment for ensureing clinker production, and feeding valve is under ensureing that coal dust claims
The important component of material smoothly intermediate bin mechanism, the effect of feeding valve are the demands that claim according to coal dust by the coal of big pulverized coal bin
Powder is transported to intermediate bin, and the structure of feeding valve includes mainly that top sets feed inlet, lower part sets out the valve body of material mouth, valve body both sides point
Not She You end cap, rotor is housed, armature spindle is driven by crossing the valve shaft driving device of two end cap setting in valve body.Feeding
Valve rotates pulverized coal conveying by its rotor, and coal dust can be from rotor and feeding valve body clearance in transmission process for traditional feeding valve
It is leaked between rotor end-face and the end cap of valve body both sides, is attached on rotor, can not be discharged from discharge port, being used for a long time may
Rotor can be caused stuck, be unable to operate normally.
Utility model content
The main purpose of the utility model is that in view of the above-mentioned problems, provide a kind of feeding valve with preventing materials accumulation structure,
So as to remove the dust accumulation on rotor in time, prevents rotor stuck, ensure feeding valve normal operation.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of feeding valve with preventing materials accumulation structure, it is main set feed inlet including top, lower part sets out the valve body of material mouth, point
It is not sealed on the end cap of valve body both sides, is mounted on the rotor of valve inner, crosses the rotor axial brake device of two end cap setting,
It is characterized in that between the end cap and rotor end-face, setting is connected in the buildup scraper plate on end cap.
The buildup scraper plate is a bar shaped bending plate being made of main body scraper plate and installation side plate, the main body scraper plate and peace
Angle between rim plate is 130 °~150 °.
Compressed air inlet is equipped on the end cap.
The discharging of gap corresponding position setting and valve body between the body base and the end cap and rotor end-face
The blowpit of mouth connection.
The utility model has the beneficial effects that：Due to being provided with buildup scraper plate between feeding valve end cap and rotor end-face,
When work, buildup scraper plate can wipe the coal dust being attached on rotor off, in particular, be equipped with again compressed air inlet and
Blowpit, compressed air are blown into from the compressed air inlet on end cap, then by coal dust between end cap and rotor end-face between
Gap is discharged via blowpit to discharge port from valve body.Thus thoroughly solve may caused by buildup the stuck phenomenon of rotor, protect
Feeding valve normal work is demonstrate,proved, feeding valve service efficiency is improved.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model；
Fig. 2 is the side view of the end cap of Fig. 1.
Fig. 3 is the I enlarged drawings of Fig. 1；
Fig. 4 is the vertical view of Fig. 1 buildup flight portions；
Fig. 5 is the structural schematic diagram of buildup scraper plate
In figure：1 rotor, 2 valve bodies, 21 feed inlets, 22 blowpits, 23 discharge ports, 3 end caps, 4 buildup scraper plates, 41 main bodys are scraped
Plate, 42 installation side plates, 43 screw holes, 5 rotor axial brake devices, 6 armature spindles, 7 compressed air inlets, 8 screws.
Specific implementation mode
The utility model is described in detail below in conjunction with drawings and examples.
Fig. 1~Fig. 5 shows a kind of feeding valve with preventing materials accumulation structure, mainly sets feed inlet 21 including top, lower part is set
The valve body 2 of discharge port 23 is sealed in the end cap 3 of 2 both sides of valve body, is mounted on the rotor 1 of valve inner, crosses two end cap 3
The rotor axial brake device 5 of the driving armature spindle 6 of setting, it is characterised in that be arranged between the end cap 3 and rotor end-face solid
The buildup scraper plate 4 being connected on end cap 3.
As shown in figure 5, the buildup scraper plate 4 is a bar shaped bending plate being made of main body scraper plate 41 and installation side plate 42,
Angle β between the main body scraper plate 41 and installation side plate 42 is 130 °~150 °.In actual fabrication, buildup scraper plate 4 is not using
Rust steel bomb reed is bent into.Screw hole 43 there are two being set on installation side plate 42, is fixed on by screw 8 on end cap 3.
Another of the utility model is characterized in being equipped with compressed air inlet 7 on the end cap 3.The inlet is direct
The gap portion being internally located between end cap 3 and 1 end face of rotor with valve body 2 is connected to, and can blow away the coal dust scraped from rotor.
The utility model is further characterized in that the gap between 2 bottom of the valve body and the end cap 3 and 1 end face of rotor
The blowpit 22 being connected to the discharge port 23 of valve body is arranged in corresponding position.
Referring to Fig. 1 and Fig. 3, arrow is coal dust flow direction in Fig. 1, and arrow is rotor direction of rotation in Fig. 3.When work,
When adhering to coal dust on the rotor end-face of rotation, buildup scraper plate 4 its 41 elasticity of main body scraper plate installed on end cap 3 is pressed on
On 1 end face of rotor, the coal dust being attached on rotor 1 can be wiped off at any time, in particular, coordinating certain compressed air from end cap 3
Compressed air inlet 7 be blown into, then air-flow make coal dust from the gap between end cap 3 and rotor end-face via blowpit 22 to going out
Material mouth 23 is discharged from valve body 2.Thus thoroughly solve may caused by buildup the stuck phenomenon of rotor.Ensure that feeding valve is normal
Work improves feeding valve service efficiency.
The above content not makes any form of restriction the structure, shape and material of the utility model.Every foundation
The technical essence of the utility model still falls within this to any simple modification, equivalent change and modification made by above example
In the range of utility model technical solution.
