Abstract
It relates to a device for cutting air flow, reducing wind speed and stable flow field, particularly a windbreak grid. It solves the shore endurance and low strength of existing wind shielding material, together with secondary pollution of hard degradation, complicated processing and higher cost. The curve grid plate is divided into C shape, S shape and omega shape. The curvature direction can be the same or in reverse alternatively. It cuts the head on whirlwind into air flows in various angles and interfering with each other, making the best of the drive and energy of the wind, reducing the turbulence degree and wind pressure, forming a low wind speed flat flow zone at the lee side of the grid wall, avoiding interference of the air current to certain area of the lee side.
Description
Technical field
The present invention relates to the facility of a kind of cutting steam, reduction wind speed and steady flow condition, be specially a kind of windbreak grid wall.
Background technology
The powder raw material many in bulk of industries such as metallurgy, mine, building, traffic all is that direct open storage ground leaves in the open environment now.Owing to be generally air storage, so when wind comes, the material of powdery can be rolled, on the one hand environment is caused serious pollution, also caused scattering and disappearing of a large amount of materials on the other hand, cause considerable economic loss to enterprise.The way that addresses this is that at present has the net structure enclosure wall of tarpaulin, solid wall, strip orifice plate or butterfly orifice plate and polyester fiber or nylon fiber braiding.Wherein, adopt tarpaulin or other thing coverage mode bigger to the operation influence in stockyard; Directly set up the entity windbreak, form in then can negative pressure region when wind is at a high speed jumped over windbreak at leeward side tornado flow (meaning as shown in Figure 6) make in air-flow disorder more; And the windbreak that the Web materials of the strip orifice plate of flat-folded formation or butterfly orifice plate and polyester fiber or nylon fiber braiding is formed (general percent opening is 30%～35%, general each stock ground windbreak will process a hundreds of thousands gravity vent at least, process numerous and diverse, the cost height), after wind is to the metope, the part air-flow passes the space interferes mutually at the windbreak leeward side and reduces the speed and the energy of wind, stoped wind that granular material is rolled, played anti-dust effect preferably, but because folding amount is big, the unit area consumable quantity is big; And because the restriction of the position of the opening direction of dish-shaped orifice plate and gravity vent, it is only better to the protection effect that single face be the wind comes from, so still will take a part of material out of when wind blows out from enclosure wall.But the Web materials of glass fiber reinforced plastic butterfly or folding crape shape plank frame and polyester fiber or nylon fiber braiding all belongs to the chemical material goods, and weatherability is poor, intensity is lower, and very difficult degraded can't recycle, and will become industrial refuse when discarded.From result of use, the butterfly orifice plate is owing to adopt glass fiber reinforced plastic to make, and ageing-resistant performance and mechanical strength are lower, and particularly in cold strong wind atmosphere, this material hardens embrittlement is easy to fracture damage.Netted flexible material then because its elasticity is bigger, often produces the bulging even the phenomenon of waving a flag when meeting strong wind, the metope load increases, and wall stability is subjected to very big threat; Easily be mingled with coal ash and dust between the fiber, metope is difficult to clean, thereby whole in use for some time metope can become very not attractive in appearance.Consider that from processing technology the orifice structure material require drills through a large amount of holes, it is higher to process numerous and diverse cost.
Summary of the invention
The present invention provides a kind of novel windbreak grid wall in order to solve problems of the prior art.
The present invention is realized that by following technical scheme a kind of windbreak grid wall comprises framework, parallelly in framework is provided with at least two curved surface screens.The curved surface screen is bent into S shape, Ω shape, C shape.The direction that its mean camber protrudes can be for also replacing reversed arrangement in the same way.
The present invention is exactly that to adopt a uniform section be the grizzly bar of curve shape and rational arrangement mode thereof, be divided into the air-flow of a plurality of different angles with head-on the wind comes from and make its phase mutual interference, so just made full use of the power and the energy of the wind comes from, Turbulent Scales of himself and blast are reduced, wind speed reduces.Thereby form the slack water area of a low wind speed at the leeward side of hoarding, avoided atmospheric circulation the interference in the hoarding leeward side certain area coverage.
As accompanying drawing 2 or 3 signals, dotted portion is the flow direction schematic diagram of wind.When the curved surface screen is bent into C shape, Ω shape, the concave and convex direction positive and negative alternate of curved surface screen is arranged, the wind of certain speed blows from the left side of windbreak, the curved surface screen of the direction of convex surface aligning wind changes the direction of wind, wind passes slit between the curved surface screen respectively along the curved surface screen, the curved surface screen back of aiming at the direction of wind at concave surface crosses the weakened part of the ability of wind; Groove behind the curved surface screen of the direction of convex surface aligning wind produces negative pressure under the wind action that curved surface screen upper and lower sides passes through fast simultaneously, thereby make the air-flow resilience of a part, the curved surface screen that concave surface is aimed at the direction of wind separates to both sides in the impact after wind that is subjected to wind resilience in the curved surface screen, just in time and the wind that passes the slit between the curved surface screen interference that crosses; The weakened part of the energy of wind; So mainly be divided into three kinds of movement air flows at this wind that blows to fast on the curved surface screen, three kinds of air-flows interact, and the energy of cancelling out each other makes at last that wind speed reduces, turbulent flow alleviates and reaches and suppress the purpose that stirs up a cloud of dust.
Anticipate as shown in Figure 4, when the curved surface screen is bent into S shape (dotted portion is the flow direction schematic diagram of wind).The wind of certain speed blows from the left side of windbreak, run into a part of wind upwards rear side bounce-back under the effect of cambered surface on the S shape behind the curved surface screen of S shape when wind, simultaneously another part wind passes the downward lateral movement of slit declivity between the adjacent curved surface screen in the effect of the lower camber side of S shape, and the slit that also has part wind directly to pass between the curved surface screen moves along a straight line; Upwards the wind of rear side bounce-back can directly disturb and hinder the wind energy that passes before the windbreak, passes to interfere mutually between the wind of oblique lateral movement down after the windbreak and the parallel wind and offsets energy wind speed is effectively reduced.
With the center line and the horizontal direction discharging angle of curved surface screen is 0～180 °.This make maintenance face between the curved surface screen parallel and and ground keep the design of certain angle can adjust wind passing the amount in slit between the curved surface screen and the direction of walking, further improve protection effect.
Compared with prior art, anticipate as shown in Figure 5, the present invention has changed original windbreak and has used the design as screen of flat board or butterfly plate, change the shape of screen into grizzly bar and rational arrangement mode thereof that the cross section is a curve form, the wind that is in turbulence state with heading on is divided into the air-flow of a plurality of different angles and makes its phase mutual interference, the power and the energy of the wind comes from have so just been made full use of, himself Turbulent Scales and blast are reduced, wind speed reduces, thereby form the slack water area of a low wind speed at the leeward side of hoarding, avoided atmospheric circulation the interference in the hoarding leeward side certain area coverage.The wind of both forward and reverse directions of the present invention has identical inhibition effect, has improved under the stock ground wind direction metope to the further barrier effect of dust, has prevented that wind is through walls and powder-material is taken out of when going out from the stock ground.And with respect to the butterfly orifice plate of existing band gravity vent, manufacture craft of the present invention is simple, directly gets final product with sheet metal compression moulding, need not again that additional processing goes out gravity vent, has reduced processing cost and has avoided waste of raw materials.
