Abstract

A transverse gravity-flow ventilation device is provided, which comprises a flashing, a rain collector and an end chain frame and is characterized in that: First, at least two layers of staggered flashings are independently fixed on the end chain frame; Second, transverse profile of the flashing is in weaves, comprising a weave peak at the middle and a wave hollow used as the rain collector at each side respectively; Third, the flashing is in arched shape in lengthwise direction, i.e., the middle part is higher and two sides are lower; the two ends are supported and fixed by the end chain frame whose top is provided with a drain slot used for leading rain water to the ground; Fourth, space between upper and lower flashings is formed to be a transverse gravity airflow passage. Ventilation device of the utility model is especially fit for working sites such as electrolytic aluminum prebake groove workshop and middle and high temperature working fields. The utility model has good ventilation effect when being integrated as workshop ceiling. If gentle breeze passes the ceiling in transverse direction, ascending airflow which increases ventilation effect will be produced as flow speed difference existing between up and down of the flashing. The device is skillfully constructed, has quite high applied value.

Description

A kind of transverse gravity gravity flow ventilation unit

Technical field

The utility model belongs to the technical field of ventilating skylight and roof ventilation, promptly proposes a kind of transverse gravity gravity flow ventilation unit that is used for workshop ventilation.

Background technology

Usually metallurgical plant or high-temperature operation workshop temperature are higher, need good ventilation condition, and sometimes these workshops are opened wide on four sides and do not established wall or large tracts of land is windowed.But like this, the pollution of environment certainly will be bigger, and the lateral ventilation effect is also undesirable.Put in a skylight, utilize the convection current gravity-flow ventilation of cold and hot air, effect is better relatively, but prior art or shutter form; Or little loft turnover panel window shape formula all there are the following problems: (1) is not rainproof, especially the strong wind rain that wafts; (2) can only be local ventilation, the workshop heat radiation is inhomogeneous.

The utility model content

The utility model has proposed the transverse gravity gravity flow ventilation unit that a kind of top large tracts of land gravity-flow ventilation of paying rent is used at existing ventilating skylight and the existing problem of roof ventilation technology.

The transverse gravity gravity flow ventilation unit that the utility model proposed comprises rain visor, rain-bearing groove and end locking frame, it is characterized in that:

(1) be provided with at least stagger mutually more than two-layer, the rain visor of independent stationary on the locking frame of end;

(2) rain visor horizontal section undulate, each trough that is made for rain-bearing groove of crest in the middle of comprising and both sides;

(3) vertically to be protruding arch be that central high both sides are low to rain visor, and two ends are supported by the end locking frame and be fixing, and locking frame its top in end is equipped with the drainage groove that rainwater is caused ground;

(4) the two-layer rain visor that will be separated by is fixed together, and the space between each layer rain visor forms the transverse gravity gas channel up and down.

The installation of up and down two-layer above rain visor of the present utility model, from the vertical direction projection, the edge of the edge of upper strata rain visor and lower floor's rain visor is tangent or overlap.

The rain visor of the superiors of the present utility model can also be that horizontal section is Jiong shape, can reduce splashing of dense raindrops like this in heavy rain.

The large tracts of land of transverse gravity gravity flow ventilation unit of the present utility model is laid the iron sheet roof in alternative existing workshop, is particularly suitable for the large-scale aluminium electrolysis shop applications.Rain visor can adopt stamped sheet metal to make, and can also apply corrosion-resistant finishes or anti-corrosive paint at thin sheet surface and contain various corrosive gas to be applicable to discharging.

Transverse gravity gravity flow ventilation unit will be determined its parameters according to the meteorological data of locality when design: (1) is wind direction all the year round, and its determines the trend of rain visor, promptly the trend of rain visor with wind direction best results when vertical; (2) maximum wind velocity, it determines vertical range between the upper and lower two-layer rain visor; (3) maximum daily rainfall, the width and the degree of depth of two rain-bearing grooves on its decision rain visor.

After being assembled into the workshop ceiling with transverse gravity of the present utility model gravity flow ventilation unit large tracts of land, because the air draft area is big, hot gas can be discharged unobstructedly in the workshop, particularly the ceiling top is as long as blown over by gentle breeze, because rain visor has wind speed poor up and down, the aerodynamically principle just can produce one ascending air, helps the ventilation in workshop especially.

Transverse gravity of the present utility model gravity flow ventilation unit low profile, delicate structure is particularly suitable for the aluminium cell workshop and the construction of high-temperature workshop in other, has very big application value.

Description of drawings

Fig. 1 is the plane of transverse gravity gravity flow ventilation unit;

Fig. 2 is its cross section (vertically view) figure;

Fig. 3 and Fig. 4 are rain visor and rain-bearing groove structural representation.

Among the above-mentioned figure, 1 is the top layer rain visor, 2 rain visors for lower floor's band rain-bearing groove, and 3 is the rain visor of bottom band rain-bearing groove, 4 is the end locking frame.

The specific embodiment

Specifically describe the structure and the characteristic of transverse gravity gravity flow ventilation unit of the present utility model now further combined with accompanying drawing, embodiment is as follows:

Embodiment 1

The metal strip template die is pressed into is with corrugated rectangular loose mail, rectangular length should be identical with the span in workshop, and these rectangular loose mails are rain visor.

Two of rain visors are welded into one with a narrow metal tape point up and down in couples, and as top layer and the 3rd layer of rain visor is welded together, the second layer and the 4th layer of rain visor are welded together, usually can the 4th layer of rain visor, as shown in Figure 3.So the rain visor two ends are fixed on the end locking frame in band gutter, its structure is shown in Fig. 2, integral hoisting is settled on the roof truss of workshop during installation, again with connect securing member such as bolt, that nut is equal to truss is fastening good, just made large tracts of land combination transverse gravity gravity flow ventilation unit with span such as workshop, its structure as shown in Figure 1, it has replaced common iron sheet roof, result of ventilating heat dissipation then is greatly to improve.

Embodiment 2

The metal strip mold pressing made be with corrugated rectangular loose mail, in addition with some (being roughly equal to sum 1/3) mold pressing system Jiong shapes.With Jiong shape band do the top layer rain visor by one hang down put about the narrow metal tape laid and the waveform rain visor spot-welded together.All above-mentioned loose mails are carried out preservative treatment, as apply erosion shield or anticorrosion with painting lacquer.

To make antiseptic loose mail with the operation identical with embodiment 1 assembles, lift on the top truss, promptly constitute the large tracts of land combination transverse gravity gravity flow ventilation unit of spans such as shown in Figure 1 and workshop, its cross section as shown in Figure 4, promptly top layer rain visor section is Jiong shape.

Must be pointed out: the utility model is asked for protection be actually by multilayer stagger mutually, not only ventilating of constituting of separately rain visor, but also the heat radiation roof of rainproof middle high-temperature workshop up and down.Need determine according to the meteorological condition of building the address as for the structural parameters of rain visor,, also should be regarded as infringement, will take corresponding legal liabilities no matter what its parameter has change therefore so long as adopted the structure identical or similar with the utility model.
