Abstract
The invention relates to an automatic tracking dust collecting device for a coal-unloading ditch. The automatic tracking dust collecting device is arranged above an impeller coal feeder and comprises air pipes, wherein a plurality of air doors are arranged at the lower parts of the air pipes; the air doors are opened and closed by air rods that are arranged on the air pipes in an inserting manner and can move upward and downward; and dust channels are formed by the air rods and the lower parts of the air rods when the air rods move upward and are communicated with the air pipes. The automatic tracking dust collecting device is arranged above the impeller coal feeder, the multiple air pipes are distributed along gap coal tanks, the air pipes are connected one another by flanges and sealing rubber baffles, so that the air impermeability of the air pipes for collecting the dust is ensured; the dust collecting efficiency is improved effectively; in addition, two constant-closed air doors are arranged on each air pipe and communicated with the air pipes; an ejecting device capable of allowing the constant-closed air doors to be opened and closed automatically is erected above the impeller coal feeder; therefore, when the impeller coal feeder operates, the opened air doors are always located above a dust source, and furthermore, the automatic tracking dust collecting efficiency is ensured.
Description
Technical field
The present invention relates to the automatic tracking dedusting device of a kind of coal receiving bunker, belong to the environmental protecting device technical field.
Background technology
Coal Conveying System of Power Plant in the course of the work because the leakage of dust, indoor often dust from flying, environmental aspect is comparatively abominable; Existing dust arrester adopts wind to take out or the mode dedusting such as spray, thereby dust arrester is mobile along with the movement of paddle coal feeder to carry out continuous dedusting to dust; But in this kind device process, the direction of wind is unordered, can not guarantee that it is in the top of paddle coal feeder all the time, and when wind is in the top of paddle coal feeder, dust can move at the moving direction of paddle coal feeder or other directions along with wind, rather than enters the dust arrester removal, thereby causes dust thoroughly not removed, still can cause a large amount of dust pollutions, have a strong impact on environment.
Summary of the invention
The present invention is directed to defects, purpose is to provide a kind of automatic tracking dedusting device of coal receiving bunker that can remove comparatively thoroughly dust.
The technical solution used in the present invention is for this reason: the present invention is arranged on the paddle coal feeder top, comprise airduct, the airduct bottom arranges some air doors, air door is plugged in wind bar on the airduct and moving up and down by one and opens and closes, one dust passage is formed at when the wind bar moves upward and airduct bottom, and this dust passage and airduct are communicated with.
Be provided with the top removal device that the wind bar is moved up and down on the described airduct.
Described airduct is formed by connecting by the airduct of some series connection, adopts flange, caulking gum baffle plate to connect between each airduct.
Advantage of the present invention is: the present invention arranges the array airduct along slit coal groove above paddle coal feeder, adopts flange, caulking gum baffle plate to connect between the airduct, guarantees the air-tightness of dedust air duct, has effectively improved efficiency of dust collection.Simultaneously be provided with two normally closed air doors at every group of airduct, and be communicated with airduct, above paddle coal feeder, set up a top removal device that can make normally closed air door automatic open close, like this, when paddle coal feeder moves, just can make the air door of unlatching be in all the time the top in dirt source, thereby reach the efficient from the motion tracking dedusting.
Description of drawings
Fig. 1 is structural representation of the present invention.
1 is that airduct, 2 is that caulking gum baffle plate, 3 is that wind bar, 4 is that top removal device, 5 is that pin-lift arrangement, 6 is paddle coal feeder among the figure.
The specific embodiment
The present invention is arranged on paddle coal feeder 6 tops, comprise airduct 1, airduct 1 bottom arranges some air doors, and air door is plugged in wind bar 3 on the airduct 1 and moving up and down by one and opens and closes, one dust passage is formed at when wind bar 3 moves upward and airduct 1 bottom, and this dust passage and airduct 1 are communicated with.
Be provided with the top removal device 4 that wind bar 3 is moved up and down on the described airduct 1.
Described airduct 1 is formed by connecting by the airduct 1 of some series connection, adopts flange, caulking gum baffle plate 2 to connect between each airduct 1.
The course of work of the present invention is: when needs carry out dedusting, it is moved upward wind bar 3 jack-up by top removal device 4, pin-lift arrangement 5 and open air door, this moment, dust entered by the dust passage, and by the wind in the airduct 1 dust was taken away removal; Airduct 1 of the present invention has some airducts 1 to be in series, and isolated between each airduct 1, like this in paddle coal feeder 6 runnings, corresponding dust the running time between each section airduct 1 can be not oversize, make it to have avoided can not dedusting because of the variation of wind direction defective, when cleaning airduct 1, short air duct structure form also is easier to cleaning, safeguards simultaneously.
The overcoat that the present invention can be communicated with at airduct 1 outer sheathed one and airduct 1 is so that the wind in the airduct 1 enters the dedusting of dust passage, and this overcoat is preferably in its air intake top and offers the wind hole, and outlet air end then is the version of opening.
Claims (3)
1. the automatic tracking dedusting device of coal receiving bunker, it is characterized in that, be arranged on the paddle coal feeder top, comprise airduct, the airduct bottom arranges some air doors, air door is plugged in wind bar on the airduct and moving up and down by one and opens and closes, and a dust passage is formed at when the wind bar moves upward and airduct bottom, and this dust passage and airduct are communicated with.
2. the automatic tracking dedusting device of coal receiving bunker according to claim 1 is characterized in that, is provided with the top removal device that the wind bar is moved up and down on the described airduct.
