Abstract
The utility mode discloses a plastic-coated cloth thermal-insulation wind cylinder, and belongs to thermal-insulation ventilation equipment used underground. The plastic-coated cloth thermal-insulation wind cylinder comprises a round cylinder body, turnups are coated at the left end of the cylinder body and the right end of the cylinder body, the left end of the cylinder body and the right end of the cylinder body are connected with steel rings through the turnups, wherein the cylinder body is composed of, from inside to outside, an inner wind cylinder made of plastic-coated cloth, a middle thermal-insulation layer and an outer wind cylinder made of plastic-coated cloth which are connected with one another in sequence. The plastic-coated cloth thermal-insulation wind cylinder is composed of the inner wind cylinder, the outer wind cylinder and the middle thermal-insulation layer, wherein the inner wind cylinder and the outer wind cylinder are made of plastic-coated cloth, the middle thermal-insulation layer is arranged between the inner wind cylinder and the outer wind cylinder, the plastic-coated cloth thermal-insulation wind cylinder is mounted in an underground roadway, cold air entering into the cylinder body from the ground flows in the cylinder body almost without the influence of high temperature in the roadway, the cold air sent out from an air outlet of the cylinder body is low in temperature, the temperature in the underground roadway is lowered effectively, and thus the problem of underground high temperature is solved.
Description
Technical field
The utility model relates to the insulation ventilation equipment that use under a kind of mine, refers to a kind of plastic coat cloth insulation air duct especially.
Background technology
Because elevated temperature heat evil has become the major natural disasters with gas, mine dust, water, the row of fighting, has been subjected to the common concern of domestic and international mining circle, the key subjects that need to be resolved hurrily that face of China's coal-mine deep mining especially.For guaranteeing downhole safety production, each mine main all is necessary for the down-hole air-supply.The air duct that tradition is commonly used 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 by air duct is bigger, therefore the temperature of cold wind raises rapidly with the prolongation of fed distance in the air duct, 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.
The utility model content
The purpose of this utility model is to provide a kind of plastic coat cloth insulation air duct, and it can guarantee that the air themperature of delivering in the underworkings is lower, is subjected to externally temperature influence little.
To achieve these goals, technical solution of the present utility model is: a kind of plastic coat cloth insulation air duct, comprise circular cylinder body, the left and right two ends of described cylindrical shell coat by flange respectively and connect steel ring, and the outer air duct that the interior air duct that wherein said cylindrical shell is made by plastic coat cloth from inside to outside successively, middle insulation layer and plastic coat cloth are made connects to form.
The utility model plastic coat cloth insulation air duct, wherein said interior air duct is the seamless circular cylindrical shell, the cylinder that described outer air duct was formed by one week of plastic coat cloth bending.
The utility model plastic coat cloth insulation air duct, the cylinder that wherein said middle insulation layer was formed by one week of sponge plate bending.
The utility model plastic coat cloth insulation air duct, two seam ends of two seam ends of insulation layer and outer air duct all are positioned at upper end separately in the middle of wherein said, and extend straight up respectively and be bonded together mutually and form the suspension ring mounting strap, along continuous straight runs evenly is provided with several through holes on the described suspension ring mounting strap, is separately installed with suspension ring on each through hole.
After adopting such scheme, the utility model plastic coat cloth insulation air duct is set to the inside and outside air duct of being made by plastic coat cloth by cylindrical shell and the middle insulation layer that is arranged between the inside and outside air duct is formed, should be incubated air duct is installed in the underworkings, when flowing in cylindrical shell from the aboveground cold air that enters in the cylindrical shell, substantially be not subjected to the influence of high temperature in the tunnel, the cold air temperature of sending from the air outlet of cylindrical shell is low, effectively reduce the temperature of underworkings, solve the insoluble difficult problem of down-hole high temperature.
Further beneficial effect of the present utility model is: inside and outside air duct is all made with plastic coat cloth, and owing to plastic coat cloth has antistatic, anti-fire-retardant, anti-advantage wear-resisting, in light weight, it can guarantee that the down-hole is safe and reliable and be convenient to install.
Further beneficial effect of the present utility model is: middle insulation layer adopts sponge plate to make, its have insulation, in light weight, be convenient to install, advantage that cost is low.
Further beneficial effect of the present utility model is: the not closed end of bending one circle of outer air duct and middle insulation layer is extended upward formation suspension ring mounting strap, make things convenient for processing, installation and cost low like this.

Fig. 1 is the front view of the utility model plastic coat cloth insulation air duct;
Fig. 2 is the local amplification view of A portion among Fig. 1;
Fig. 3 is that B-B among Fig. 1 is to sectional view.
Below in conjunction with accompanying drawing, be described further by the utility model of embodiment;
The specific embodiment
As shown in Figure 1 to Figure 3, the utility model plastic coat cloth insulation air duct comprises circular cylinder body 1.Cylindrical shell 1 is from inside to outside successively by interior air duct 4, middle insulation layer 5 and outer air duct 6 bonding forming.Interior air duct 4 is seamless circular cylindrical shells of being made by plastic coat cloth.The cylinder that middle insulation layer 5 was formed by one week of sponge plate bending.The cylinder that outer air duct 6 was formed by one week of plastic coat cloth bending.The left and right two ends of cylindrical shell 1 are coated on the end by flange 2 with steel ring 3 respectively, and flange 2 and barrel outer surface are bonded together.Two seam ends of middle insulation layer 5 and two seam ends of outer air duct 6 all are positioned at the upper end, and extend straight up respectively and be bonded together formation suspension ring mounting strap 7 mutually.Along continuous straight runs evenly is processed with several through holes on the suspension ring mounting strap 7, is separately installed with suspension ring 8 on each through hole.
During use, the steel ring 3 mutual sockets of several the utility model plastic coat cloth insulation air ducts by the end are linked together, be distributed in the tunnel, and with each the insulation air duct each suspension ring 8 connect steel wire respectively, each steel wire other end is individually fixed on the roof of tunnel, make these connect plastic coat cloth insulation air duct and be hung on the tunnel, the cold air that well is outer is introduced in the tunnel by cylindrical shell 1, solves the insoluble difficult problem of down-hole high temperature.
The above embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
