Pollution.The cleaner that thermal power plant uses at present, mostly multitube impact dust remover, sack cleaner, water leaching dust-arrest device.At present
Cleaner dust removing effects it is not thorough, as bag-type dust amount it is big after easy combustion explosion, and can produce in the when of falling powder secondary
Pollution.
Utility model content
The technical problems to be solved in the utility model, it is to provide a kind of belt feeder without outer row's dedusting and cleaning device, can solves
Certainly the above-mentioned problems in the prior art.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in:
A kind of belt feeder is set without outer row's dedusting and cleaning device, including bending roller, driving drum in two cylinder periphery
Coal conveyer belt is equipped with, deflector chute is provided with above the coal conveyer belt, dust holdback is provided with the deflector chute end, in institute
State dust holdback side and be provided with coal spout, dust collector is provided with the coal spout opposite side, it is another in the deflector chute
End is provided with negative pressure damping device, and discharge pipe is provided between the dust collector and negative pressure damping device.
As restriction, middle part is provided with filter in the discharge pipe, and the filter includes screen pack and the 5th mist
Change nozzle;Exhaust blower is provided with the air-out pipe end.
Limited as another kind, belt cleaning scraper and the 4th atomization spray are provided with below the coal conveyer belt and driving drum
Mouth.
Limited as further, the dust holdback, dust collector, belt cleaning scraper, the side of discharge pipe
Or inside is equipped with atomizer.
The utility model as a result of above-mentioned structure, its compared with prior art, acquired technological progress is:
(1) belt feeder is installed without outer row's dedusting and cleaning device, does not remove any existing facility.
(2) flight portion has the function of repeatedly scraping coal, spray clean, efficiency high, but not belt is damaged.
(3) atomizer injection flow rate is small and does not interfere with the water content of coal.
(4) treating flour dust and collection discharge are carried out simultaneously, have both administered environmental pollution, it is not necessary to which dust is subsequently located
Reason, the input to use manpower and material resources sparingly and twice laid, increase economic efficiency.
It is of the present utility model simple in construction, coal dust can be made to form coal slurry with water, avoid arranging outside coal dust, improve the profit of coal
With rate and improved the environment of thermal power plant and surrounding, and be avoided that potential danger caused by other cleaners.

Embodiment
With reference to the accompanying drawings and examples, the utility model is expanded on further.In the following detailed description, only pass through
Bright mode describes some one exemplary embodiments of the present utility model.Undoubtedly, one of ordinary skill in the art can be with
Recognize, can be with a variety of modes to described in the case of without departing from spirit and scope of the present utility model
Embodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting the protection of claim
Scope.
As shown in figure 1, according to the belt feeder of the utility model embodiment without outer row's dedusting and cleaning device, including bending roller
8th, driving drum 9, two cylinder periphery is provided with coal conveyer belt 11, deflector chute is provided with above the coal conveyer belt 11
10, dust holdback 2 is provided with the end of deflector chute 10, coal spout 7 is provided with the side of dust holdback 2, in described
The opposite side of coal spout 7 is provided with dust collector 4, negative pressure damping device 12 is provided with 10 another end of deflector chute, in the powder
Discharge pipe 1.1 is provided between dirt collector 4 and negative pressure damping device 12.
As preferable, middle part is provided with filter 6 in the discharge pipe 1.1, and the filter 6 includes screen pack
6.1 and the 5th atomizer 3.5;Exhaust blower 1 is provided with the end of discharge pipe 1.1.
As preferable, the coal conveyer belt 11 and the lower section of driving drum 9 are provided with the atomization spray of belt cleaning scraper 5 and the 4th
Mouth 3.4.
Further, the dust holdback 2, dust collector 4, belt cleaning scraper 5, discharge pipe 1.1 side or
Inside is equipped with atomizer.
Operation principle of the present utility model is:
Coal enters in deflector chute 10 by coal spout 7, and coal conveyer belt 11 is driven by bending roller 8 and driving drum 9
Reciprocation cycle rotates, and because airborne dust occurs during defeated coal, being arranged at the dust holdback 2 of the one end of deflector chute 10 prevents by dust
Fall, is provided with the second atomizer 3.2 in dust collector 4, dust is drenched into collection form coal slurry and fall after rise to deflector chute 10, when
When coal passes through discharge pipe 1.1, exhaust blower 1 is to outside air draft, the screen pack 6.1 on filter 6 that the lower section of exhaust blower 1 is set
Moistened by the 5th atomizer 3.5, form unique moisture film and gas channel in the screen pack 6.1, micron order grit can be by
Interception is got off, and is washed away by current in falling to deflector chute 10, and negative pressure damping device 12 makes discharge pipe 1.1 and the tail of dust collector 4
The negative pressure cavity in portion has stable negative pressure to produce, and prevents space air from entering in deflector chute 10.4th atomizer 3.4 will adhesion
Coal dust moistening on coal conveyer belt 11, it is suppressed that coal dust fly upward and scraper and the dry of belt are scraped.
Quick flowing is produced by dusty gas and water smoke in the presence of Throttle Principle according to aerodynamic principle, makes water
Mist and dusty gas form eddy flow, hit friction and are captured by dust-catching board, the water smoke and dust captured is formed on dust-catching board
Coal slirne, dust-catching board produce quick tremble under the dragging of coal stream and accelerate the falling speed of coal slirne, coal slirne is covered in coal
Flow table face prevents coal stream from producing airborne dust in course of conveying.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
