Abstract
The invention discloses a kind of are arranged to import and export the device for preventing coal dust excessive in totally-enclosed coal bunker, and it includes wind turbine, air guide duct, band-like air outlet, electrical equipment, control system which, which is arranged in totally-enclosed coal bunker inlet and outlet top or both sides, the device,.The device generates from the top down or from two sides to inlet and outlet center to the air-flow blown, and form air curtain does not influence vehicles while passing coal bunker while effectively stopping that coal dust is excessive in storehouse.
Description
Technical field
The invention belongs to field of environment protection, and in particular to a kind of device for preventing totally-enclosed coal bunker inlet and outlet coal dust excessive.
Background technology
Much the Railway Coal dispatching station of outdoor coal yards, Along Railway is raised due to encountering strong wind during operation and storage
Dirt is seriously polluted, is included in undertaking treatment within a prescribed limit of time object by environmental protection administration, it is desirable that implement totally-enclosed measure, otherwise will face halt production,
Shut down risk.
But Railway Coal dispatching station, since train will pass through, coal yard both ends can not be closed, when train being caused to pass in and out, largely
Coal dust is overflowed from inlet and outlet, and environmental requirement is not achieved.
Invention content
The object of the invention is intended to provide a kind of setting of structurally simple, economical practicality and is prevented in totally-enclosed coal bunker inlet and outlet
The excessive device of coal dust, it can prevent coal dust in coal bunker it is excessive while, do not influence vehicles while passing.
In order to achieve the above objectives, the present invention uses following solution：
A kind of totally-enclosed coal bunker vehicles while passing one's intention as revealed in what one says proscenia, is arranged on the top or both sides that totally-enclosed coal bunker is imported and exported, is used for
It prevents coal dust excessive, is generated from the top down or from two sides to inlet and outlet center to the air-flow blown by air curtain apparatus, form air curtain,
While effectively coal dust is excessive in blocking storehouse, vehicles while passing coal bunker is not influenced.
The air curtain apparatus is made of wind turbine, air guide duct, band-like air outlet, electrical equipment, control system.
The principle of the present invention is：The device for preventing coal dust excessive of top or both sides, production are imported and exported by being arranged in coal bunker
It is raw to form air curtain from the top down or from two sides to inlet and outlet center to the air-flow blown, while effectively stopping that coal dust is excessive in storehouse,
Vehicles while passing coal bunker is not influenced.
Compared with prior art, the invention has the advantages that：
1, the present invention is effectively stopped in storehouse by the device for preventing coal dust excessive in the inlet and outlet setting of totally-enclosed coal bunker outside coal dust
It overflows, it is economical and practical.
2, the present invention solves the problems, such as totally-enclosed coal bunker vehicle pass-through and entrance flour dust overflow.

Fig. 1 is structure shaft side figure when the air curtain apparatus of the present invention starts.
Fig. 2 is cross-section diagram when coal conveyor passes through air curtain apparatus.
Fig. 3 is cross-section diagram when coal conveyor passes through air curtain apparatus.
Fig. 4 is the principle of the present invention figure.
Fig. 5 is the control principle drawing of the present invention.
In figure, 1- closes rack 2- wind turbine 3- air outlet 4- steel bracket 5- high-speed flow 6- coal conveyors.
Specific implementation mode
Certain Railway Coal dispatching station, 1 kilometer of goods yard length, has had totally-enclosed coal bunker.But due to being shipped by train
Coal, train inlet and outlet in coal bunker both ends can not be closed, directly open, cause coal dust in storehouse excessive.It is passed in and out in coal bunker both ends train
The mouth position sides Liang Ge are provided with the device for preventing coal dust excessive, from two sides to inlet and outlet center to blowing gas stream, form air curtain, have
While coal dust is excessive in effect blocking storehouse, vehicles while passing coal bunker is not influenced, dust-proof effect is good.
A kind of totally-enclosed coal bunker vehicles while passing one's intention as revealed in what one says proscenia is arranged on the top or both sides that totally-enclosed coal bunker is imported and exported,
For preventing coal dust excessive, is generated from the top down or from two sides to inlet and outlet center to the air-flow blown, formed by air curtain apparatus
Air curtain does not influence vehicles while passing coal bunker while effectively stopping that coal dust is excessive in storehouse.
Shown in Fig. 1, air curtain apparatus is made of wind turbine 2, air guide duct, band-like air outlet 3, electrical equipment, control system.
Control system is by microwave sensor, PLC controller, motor, wind turbine composition.
Its workflow is as follows：Microwave induced detector detect vehicle by when, pulse signal is transmitted to main controller, it is main
Control device notifies motor operation after judging, while monitoring motor rotations, goes slowly to notify motor to be reinforced when certain and to enter
Operation.Motor does positive operation after obtaining certain running current, power is transmitted to wind turbine, the high-speed flow that wind turbine generates is in channel
Place forms one of air curtain, and dust in storehouse is prevented to be carried over outside storehouse.
Claims (5)
