Abstract
The utility model discloses a heat preservation wind cylinder applied to borehole operation. The heat preservation wind cylinder comprises an inner wind cylinder and an outer wind cylinder arranged on the outer side of the inner wind cylinder. A heat preservation cavity is formed between the inner wind cylinder and the outer wind cylinder. Pieces of connection soft cloth are respectively arranged on two ends of the inner wind cylinder. Orifices are arranged on the connection soft cloth. The inner wind cylinder, the outer wind cylinder and the connection soft cloth are made of the same soft materials. The heat preservation wind cylinder well solves the problem that wind supply temperature is greatly affected by the hot and wet environment outside the wind cylinder in the supply process of cold wind and hot wind, effectively guarantees the wind supply temperature of a wind outlet, and has the advantages of simple hanging, light weight, simple manufacturing, low cost, and the like.
Description
Technical field
The utility model relates to a kind of insulation air duct, relates in particular to a kind of insulation air duct that is applied to underground work, belongs to the insulation ventilation equipment field of industries such as mine, tunneling.
Background technology
Along with the increase of the pit mining degree of depth and the raising of mining machinery level, the quantity of China's high-temperature mine increases day by day, and heat evil degree also is on the rise.Elevated temperature heat evil has become the important natural calamity with gas, mine dust, water, the row of fighting, has received the common concern of domestic and international mining circle, especially the key subjects that need to be resolved hurrily that faced of China's coal-mine exploitation.
For administering the elevated temperature heat evil of development end, generally adopt mechanically refrigerated cooling method both at home and abroad, utilize air cooler to cool to distinguished and admirable, cooled wind circulation is crossed air duct and is carried out air feed to the cooling place.The conventional air duct is not owing to adopt the insulation measure; Differ bigger because of distinguished and admirable in the air duct with the outer tunnel of air duct airflow temperature simultaneously; Heat output through air duct is bigger, so the temperature of cold wind raises rapidly with the prolongation of fed distance in the air duct, and airflow temperature and tunnel airflow temperature are more or less the same when arriving with cold place; Cold loses many on the way, and effectively the cooling amount is little.Therefore, guaranteeing under the lower outlet temperature of air cooler that the fed distance that how effectively to improve cold wind is to solve driving and cooling and improve the key of effective cooling amount.
The utility model content
The embodiment of the utility model has proposed a kind of insulation air duct that is applied to underground work, can fine solution technical problem recited above.
The technical scheme that the utility model adopted is:
A kind of insulation air duct that is applied to underground work, the outer air duct that comprises interior air duct and be positioned at the air duct outside, interior air duct with outside form incubation cavity between the air duct, the two ends of said interior air duct are provided with the connection soft cloth respectively, offer the aperture on the said connection soft cloth; Air duct, outer air duct and connection soft cloth are to be processed by the flexible material of identical material in said; The inside of incubation cavity is along being provided with the fixedly soft cloth that is connected interior air duct and outer air duct on the direction of interior air duct and exogenous wind tube length degree, and fixedly the number of soft cloth is four, is evenly arranged in the inside of incubation cavity.
As the advantageous embodiment of the utility model, the lateral surface of said outer air duct is along being symmetrical set two groups of suspension ring on the exogenous wind tube length degree direction.
The beneficial effect of the utility model is:
A kind of insulation air duct that is applied to underground work; Finely solved hot and cold distinguished and admirable course of conveying wind pushing temperature and receive the outer thermal and humidity environment of air duct to influence bigger problem; Effectively guaranteed the wind pushing temperature of air outlet, and have hang simple, in light weight, make advantages such as simple, that cost is lower; The inner air of incubation cavity slowly flows, and has prevented that humid air dewfall in incubation cavity from coagulating water, in the installation process of interior air duct, does not does not import and export the restriction of direction; The utility model has effectively been avoided the sagging of interior air duct, and air duct overlaps with the axis of outer insulation air duct all the time in guaranteeing, has avoided interior air duct and has been incubated air duct outward and contacts and cause the lost of distinguished and admirable cold; In addition, the utility model installation and removal are all very convenient, and are easy to fold.
Description of drawings
Fig. 1 is a kind of structural representation that is applied to the insulation air duct of underground work;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:
In conjunction with Fig. 1, shown in Figure 2, a kind of insulation air duct that is applied to underground work, air duct 1 and outer air duct 2 in comprising, wherein, interior air duct 1 is positioned at the inboard of outer air duct 2, during air-supply, interior air duct and outside formation incubation cavity 3 between the air duct; Interior air duct 1 is provided with and connects soft cloth 4, and the number that connects soft cloth is two, and the two ends of air duct 1 in laying respectively at offer the radius small apertures on the connection soft cloth.During air-supply, interior air duct 1 is heaved with outer air duct 2 and all is cylindric, connects soft cloth 4 and is annular, and preferred, the width that connects soft cloth 4 is 5 centimetres.Because the radius in aperture is less, the gas that gets into incubation cavity is less, and distinguished and admirable speed is less in incubation cavity, plays the effect of insulation on the one hand, again because of the flowing of air, has prevented in incubation cavity, to produce and has coagulated water on the other hand.
Interior air duct 1, outer air duct 2 and to connect soft cloth 4 be to be processed by the flexible material of identical material, and outer air duct 2 has good heat insulation effect.
In the air-supply process, the axis runout of interior air duct 1 and outer air duct 2 is at the fixing soft cloth 5 of the set inside of incubation cavity; Air duct and outer air duct in being used to connect; Preferably, fixedly the number of soft cloth 5 is four, is evenly distributed on the inside of incubation cavity 3; Fixedly be arranged on the medial surface of outer air duct outside one of the soft cloth long edge on the length direction of air duct; In fixedly the length direction mountain of air duct is arranged in another long edge of soft cloth on the lateral surface of air duct, the fixing equal in length of the length of soft cloth and interior air duct 1, fixedly the width of soft cloth is internal diameter poor of outer air duct 2 and interior air duct 1.
Be symmetrical set two groups of suspension ring 6 on the lateral surface upper edge exogenous wind tube length degree direction of air duct 2 outside, suspension ring 6 are used for the fixing of external air duct 2.
Certainly, the foregoing description is not the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Should be noted that those skilled in the art under the instruction of this manual, any change of being made, distortion, variation or replacement form all should drop within the protection domain of the utility model, ought to receive the protection of the utility model.
