Abstract
The present invention relates to a kind of dust-protection type grab type ship unloaders hopper, including hopper body, the dust-proof guard being arranged on hopper body, dust-proof guard top, which is equipped with to inclined time of hopper body central direction dirt dog-ear, hopper side, is additionally provided with the dust-proof check apron of packaged type.Compared with prior art, the present invention forms opposite confined space by making to greatest extent above ship unloaders hopper, can so reduce the dust during the grab bucket blowing caused by the wind in the external world, is also avoided that and raises dust since grab bucket self-operating produces air-flow.
Description
Technical field
The present invention relates to a kind of dump skip, more particularly, to a kind of dust-protection type grab type ship unloaders hopper.
Background technology
Grab type ship unloaders are the equipment for being used to unload shipping coal in thermal power plants.Grab type ship unloaders utilize grab bucket
Ship coal is captured, is captured and is acted coal is sprinkled into hopper by the bucket of opening above hopper after ship coal.Coal is sprinkled into material in hopper
Coal dust can be produced during bucket, pollutes surrounding enviroment.
Current most of grab type ship unloaders hopper port dust preventions mainly have 1) hopper port installation water spray；2) hopper
Mouth installs dry fog dedusting additional；3) mode such as hopper port sprinkling dust suppressant.But these types of mode deposits the unconspicuous problem of dust-proof effect,
The unconspicuous reason of dust-proof effect is caused to be mainly the following：1) environment of ship unloaders work is mainly in rivers,lakes and seas, throughout the year
It will be subject to monsoon, convection weather, strong wind can dispel the dust of hopper port.2) ship unloaders are grabbed bucket can produce sky into material bin top
Flow of air, moving air can dispel hopper port dust.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of good dustproof effect
Dust-protection type grab type ship unloaders hopper.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of dust-protection type grab type ship unloaders hopper, including hopper body, the dust-proof guard being arranged on hopper body, institute
Vertical baffle is additionally provided with the dust-proof guard stated, increases the height of dust-proof guard, the top of the vertical baffle is equipped with to material
Struggle against inclined time of direction of body central dirt dog-ear.
Height of the height that the dust-proof guard and vertical baffle are formed higher than the bucket body grabbed bucket in hopper.
As more preferred embodiment, movable air door is further opened with vertical baffle, top movable is connected to vertically
The top of opening on baffle is simultaneously rotated along the tie point.
As preferred embodiment, movable air door being uniformly distributed on vertical baffle, its area accounts for vertical baffle
The 1/2-2/3 of the gross area, when wind-force reaches certain rank, such as while reaching 6 grades, can automatically open up, reduce wind load into
The increase of one step.
As preferred embodiment, the angle returned between dirt dog-ear and vertical baffle is 40-60 °, in above-mentioned angle model
Can be best in enclosing play the role of deceleration depositing dust, after grab bucket is opened, the dust raised can climb upwards along vertical wind shield,
If the dust air-flow that returning dirt dog-ear plate can make to climb upwards is stopped, deceleration, the effect of depositing dust are played.
As preferred embodiment, the top for returning dirt dog-ear also hangs with flexible dustproof curtain, can further hinder dust
The diffusion of air-flow, further slows down, depositing dust.
As preferred embodiment, rear check apron is further included, is arranged on the side of hopper, is controlled through driving device living up and down
It is dynamic.In addition, rear check apron makes to obtain using rubber material, is also prevented from touching with hardness during grab bucket abnormal running
Hit.
No matter which kind of dust-suppression method used, the closing of good hopper port is all the prerequisite bar for finally obtaining optimal anti-dust effect
Part, compared with prior art, the present invention form opposite confined space by making to greatest extent above ship unloaders hopper, so
It can prevent the wind in the external world from causing the airborne dust during blowing, also be avoided that what is produced due to grab bucket self-operating above hopper port
Airflow dust.Dust can be inhibited in root caused by hopper blowing by such method, so as to obtain good
Dust-proof effect.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
In figure, 1- hoppers body, 2- dust-proof guards, 3- vertical baffles, 4- return dirt dog-ear, 5- flexible dustproofs curtain, 6- grab bucket,
Check apron after 7-.
Embodiment
With reference to specific embodiment, the present invention is described in detail.Following embodiments will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection domain.
Embodiment 1
A kind of dust-protection type grab type ship unloaders hopper, its structure are arranged on hopper sheet as shown in Figure 1, including hopper body 1
Dust-proof guard 2 on body 1, is additionally provided with vertical baffle 3 on dust-proof guard 2, for increasing dust-proof height, dust-proof guard 2 and perpendicular
The height that straight baffle 3 is formed is higher than height of the bucket body of grab bucket 6 in hopper, and the wind shield that ship unloaders hopper port installs additional can increase
The front face area of ship unloaders, adds the wind load that ship unloaders are subject to, and the wind loading rating on ship unloaders is influential.This is also
It is why other similar enterprises dare not increase one of hopper wind shield height, the important innovations point of the application easily to exist
In being further opened with movable air door on vertical baffle 3, top movable is connected to the top of the opening on vertical baffle and along the connection
Point rotates.Movable air door being uniformly distributed on vertical baffle, its area account for the 1/2-2/3 of the gross area of vertical baffle, this reality
It is 2/3 to apply area accounting in example, so as to be automatically opened up when wind-force reaches 6 grades, reduces the further increase of wind load.
The top of vertical baffle 3 is equipped with to inclined time of hopper body central direction dirt dog-ear 4.Dirt folding is returned in the present embodiment
Angle between angle 4 and vertical baffle 3 is 40-60 °, and the angle in the present embodiment uses 40 °, can in above-mentioned angular range
Best plays the role of deceleration depositing dust, and after grab bucket is opened, the dust raised can climb upwards along vertical wind shield, if returning dirt folding
The dust air-flow that gusset can make to climb upwards is stopped, plays deceleration, the effect of depositing dust.
In addition, also hanging with flexible dustproof curtain 5 at the top for returning dirt dog-ear 4, the diffusion of dust air-flow can be further hindered,
Further slow down, depositing dust.Rear check apron 7 is further included, is arranged on the side of hopper, is controlled through driving device up and down.This sample
There are wind shield and check apron in three faces of bucket top, and intilted baffle is arranged at top, farthest surrounds grab bucket, form opposite envelope
Airborne dust in the space closed, so grab bucket discharge process is largely eliminated, and rear check apron 7 can be made to using rubber material
Arrive, with the hard collision for preventing and grabbing bucket during abnormal running.
The specific embodiment of the present invention is described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring the substantive content of the present invention.
