Embodiment

Below in conjunction with accompanying drawing the present invention is further described:

As Fig. 3, Fig. 4, a kind of trench air-blowing solidifying chamber, mainly form by curing room, vertical ventilation pipe 1 ', trench 2 ', backwind tube 3 ', trench air distribution plate 4 ' and water conservancy diversion aerofoil 5 ', described curing room bottom is provided with trench 2 ', trench 2 ' both sides are provided with the vertical ventilation pipe 1 ' that is communicated with trench 2 ', the curing room inner top is provided with backwind tube 3 ', is provided with water conservancy diversion aerofoil 5 ' in the trench 2 '.

Vertical ventilation pipe 1 ' is a stainless steel tube.

Trench 2 ' is raised to two gradually by the centre, and the sectional area in trench air channel is reduced to two ends gradually by the centre.

Trench air distribution plate 4 ' is provided with air outlet 4 ' 0.

The air outlet 4 ' 0 of trench air distribution plate 4 ' is increased to two ends gradually by the centre.

Embodiment as shown in Figure 4 is as follows: trench formula air-distribution device, it is made up of vertical ventilation pipe, trench, trench cover plate, air distribution plate, baffler.Be characterized in that trench is to be raised gradually to two by the centre, the sectional area in air channel (trench) is reduced to two ends gradually by the centre, cover plate also is to be increased gradually to two ends by the centre, thereby guarantees that wind also can blow out uniformly to two ends.

Operation principle of the present invention is: because the degree of depth of the mixed curing room of general brick can be deep, the air quantity of the end of supply air system is all smaller even do not have wind to go out, the trench 2 ' of this design is to adopt terminal high the rising into constant slope in low two, middle part, as Fig. 5, because having institute to terminal back wind speed, weakens wind, adopt the mode of this design to get over the end that arrives trench 2 ', sectional area is more little, thereby guaranteeing also can have enough winds to go out at trench 2 ' end. and entering two water conservancy diversion aerofoils 5 ' of trench 2 ' preceding usefulness the flow direction on correcting wind direction both sides, better avoid unnecessary loss thereby avoid a large amount of wind directly to blow to the living vortex of ground furrow bank miscarriage last time.The cover plate of trench is a trench air distribution plate 4 ', also done the corresponding techniques change, as Fig. 6, for guarantee wind to two sections also can blow out uniformly, air outlet 4 ' the 0 perforate size of trench air distribution plate 4 ' also is to the proportional gradually increase in two ends by the centre, make the cover plate perforate sectional area at past more trench two ends big more, reduce the flow that local resistance guarantees wind, thereby further guarantee to solidify the uniformity of indoor wind when dry.

Trench cloth wind explanation of the present invention:

When adopting trench air-blowing mode cloth wind, wind is sent into from the centre to trench two side-blowns, and when the sectional area of trench equated, wind did not almost have wind to go out to the more little air port to the end of back blast more.According to following formula can release when the trench sectional area to both sides more and more hour, can guarantee that wind energy blows out uniformly from trench.Why will trench diminish gradually?

According to the dynamic pressure formula:

$\mathrm{\ΔR}=\frac{{\mathrm{\ω}}^2\mathrm{\ρ}}{2}$

Δ R-------gas dynamic pressure

ω-------air-flow velocity

ρ--gets 1.204 during 20 ° of-----gas densities

According to V=F ω

V-------exports air quantity

The F-------discharge area

V ₁＝F ₁ω ₁：V ₂＝F ₂ω ₂；

In order to make every section trench keep the dynamic head that equates, even Δ R ₁=Δ R ₂, must make ω in the trench ₁=ω ₂=ω ₃

Must be F so ₁＞F ₂＞F ₃, V ₁＞V ₂＞V ₃, do the sloping for this trench and make that the wind speed in every section trench is basic identical, even their dynamic pressure Δ R ₁=Δ R ₂=Δ R ₃Also identical, keep certain dynamic pressure and wind speed

Will the air port of why drying become big gradually?

According to local resistance crushing formula:

$\mathrm{\ΔP}=\mathrm{\ξ}\frac{{\mathrm{\ω}}^2\mathrm{\ρ}}{2}$

Δ P-------local resistance crushing

ω-------air-flow velocity

ρ--gets 1.204 during 20 ° of-----gas densities

ξ-------coefficient of partial resistance

According to V=F ω

V-------exports air quantity

The F-------discharge area

Make V ₁=V ₂Must make Δ P ₁=Δ P ₂But because V ₂The road warp of point is greater than V ₁The road warp of point, Δ P ₂＞Δ P ₁For the crushing that makes them equates, have only the aperture area of increasing F to make F ₂＞F ₁ω like this ₁＞ω ₂Because F ₂The wind speed ω of point ₂↓ descend, according to formula:

Reach relative crushing balance for each point like this

Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and scope are limited; do not breaking away under the design concept prerequisite of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention, the technology contents that the present invention asks for protection all is documented in claims.
