Description
Technical field
The present invention relates to dust arrester, especially on a large scale open area spray for dust suppression machinery.
Background technology
Be applicable to the common air-assisted type spraying machine of other purposes such as factory or mining site, by the water of air duct jet atomization, make the dust of droplet in air be combined depositing dust.Higher than traditional running water spraying efficiency, also save more water resource.The stifled mist wall of water smoke formation one of nozzle ejection reaches stop dust recycling and adheres to dust and lands ground to reach dedusting and anti-dust effect in use.But air-assisted type spraying machine has several general problem in use:
1. common air-assisted type spraying machine can only spray place by regulating air duct angle to change, so the mist wall formed has dead angle on a large scale, its water smoke also cannot cover space nearby.
2. the limited coverage area of effective droplet.Water smoke branch in the middle part of course of injection collides mutually, and combines, and forms large droplet.This large droplet due to quality large, the distance of carrying with the wind is near, so the speed of sinking is fast.Seem that water smoke also has covering nearby, but the diameter of this large droplet is far longer than 10 μm nearby, diameter due to general harmful dust is less than 10 μm, they collide with each other adhere to probability very low, its dust removing effects extreme difference, the stop dust recycling effect of mist wall is also low, so, the effective droplet of large droplet right and wrong.The effective droplet being less than 10 μm is then easily delivered to farther place by wind.
China Patent No. CN104785047A horizontal moving dedusting atomization plant, discloses the atomization jetting device of slide block and the slide block transverse shifting control device that a kind of base is slidably installed, decreases dead angle.Its weak point installs difficulty, and cost is high, and still unresolved water smoke cannot cover the problem in space nearby.
The spray for dust suppression machine drum device of China Patent No. CN201520160472, by increasing air duct frame and rotating the turning cylinder be assemblied on air duct frame, make air duct do high frequency to move up and down, solve the problem that in prior art, air duct effective coverage range is limited, its weak point is that each parts must ensure that high strength makes air duct do long-time high frequency motion.Technical difficulty is high, nor economical.In addition, Wu Qiang space can be produced in air duct moves up and down.
In practicality, the air-assisted type spraying machine combination of useful more than two different ranges, reaches the covering of FR effective droplet.
Summary of the invention
Problem to be solved by this invention overcomes the deficiencies in the prior art, provides a kind of aerosolater, the coverage of effective droplet is made to become large, and without dead angle, namely, also can accomplish that effective little droplet covers on hand, make mist wall expanded range wide, intercept dust more efficient.The cost improved is low, thus Improving The Quality of Products.
For solving the problem, basic conception of the present invention is: time larger than air outlet according to Bernoulli's theorem air inlet, wind speed accelerates, otherwise diminishes.If fan air drum is divided into two parts, air duct flow velocity can be gone up fast, spray far away.Lower air duct flow velocity is slow, spray near.To combine between the higher and lower levels, the effective coverage range of water smoke just increases greatly, can also by the size regulating the angle of dividing guide plate to adjust this coverage.
Technical scheme of the present invention is, a kind of air-assisted type spraying machine comprises air blast leaf, air duct, spray nozzle, it is characterized in that: is also provided with dividing guide plate, and air duct air-flow is split by this dividing guide plate, makes air duct form different runners.Dividing guide plate can be movable adjustable, also can be fixing, also detachable to replace different size.Dividing guide plate and airflow direction are certain Windward angle α, each runner inlet and outlet size of air duct is changed, and various flows road has different wind speed, high wind speed can water smoke be sent farther, low wind speed can water smoke be sent nearer, thus form the covering of FR effective droplet.
In air duct, dividing guide plate can be one piece also can be polylith.Namely air duct can have multiple runner.
Beneficial effect of the present invention: a typhoon assisted type spraying machine, do not need the air duct of this machine to do high frequency to move up and down, just can reach and not only have at a distance, and have the little droplet of a large amount of effective elimination harmful dusts nearby yet, increase considerably the efficiency of dust collection of air-assisted type spraying machine, and do not stay dead angle; The present invention only need increase critical component in the structure of original common air-assisted type spraying machine, easy for installation, manufactures simple, and its convenience and cost and common air-assisted type spraying machine are as good as.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the invention will be further described.
Fig. 1 is the effective Pcnten-1 yne-4 figure of prior art spray for dust suppression
Fig. 2 is the effective Pcnten-1 yne-4 figure of spray for dust suppression of the present invention.
Fig. 3 is structural profile schematic diagram of the present invention.
Detailed description of the invention
Fig. 1 is the effective Pcnten-1 yne-4 figure of prior art spray for dust suppression.For one spray penetrates.
Fig. 2 is the effective Pcnten-1 yne-4 figure of spray for dust suppression of the present invention.Upper and lower two strands of sprays, above be at a high speed below be low speed, intersection is that mixed flow is at the uniform velocity with, and defines the covering of FR effective droplet.
Fig. 3 is structural profile of the present invention.A slice dividing guide plate 1 is here set, deflector is connected on live axle 2, regulate its Windward angle α to reach required droplet coverage, afterwards dividing guide plate 1 is fixed.The distinguished and admirable of flabellum 4 blowout is branched to upper channel 5 and lower channel 6 by dividing guide plate 1, the wind speed of upper channel 5 is higher than the wind speed than lower channel 6, therefore sent farther from the first half of the water smoke of nozzle 3 ejection by the high speed winds from upper channel 5, the latter half then by the low speed wind of lower channel 6 in nearer position, thus to achieve by the nearly covering to effective droplet on a large scale far away.
The present invention is not limited only to above-mentioned embodiment.Other form with the invention belongs to same basic conception, also belongs to protection scope of the present invention.
Technical solutions according to the invention are established for solving technical problem to be solved by this invention, relative to technical problem to be solved, that it establishes the integrality of its technology contents.When it being implemented in concrete product, realizing the necessary technical characteristic of this product can more than the summation of technical solution of the present invention for the essential features of technical solution problem.
The implication of each technical characteristic of the present invention to specifications in the definition of each proper noun; There is no special definition, introduce common practise and the technology of the art, but the category of this knowledge is limited to technical problem to be solved by this invention, basic conception, technical scheme, the effect of the function possessed in the present invention in conjunction with it, role and generation, namely the content with reference to description and accompanying drawing thereof is understood, the word wording of this feature name is not the restriction of its implication, in order to avoid produce ambiguity of the present invention.
