Abstract
The utility model relates to a heat preservation wind-cone, which comprises a circular wind-cone body and a connecting ring, wherein, the wind-cone body is made of wind-tight flexible material, both ends of the wind-cone body are respectively connected with a connecting ring in a sealing way. The heat preservation air duct is characterized in that a heat preservation sleeve barrel the diameter of which is larger than that of the wind-cone body is arranged outside the wind-cone body, both ends of the heat preservation sleeve barrel are also connected with the connecting ring in a sealing way, at least an air hole is arranged on the wind-cone body, and a heat preservation layer is formed in the space between the wind-cone body and the heat preservation sleeve barrel. When the air wind-cone blows air, air with a certain pressure in the wind-cone body passes through the air hole into the heat preservation layer between the wind-cone body and the heat preservation sleeve barrel, air has good heat isolation and heat preservation performance, therefore, when air flows in the wind-cone, air is not influenced by high temperature in the lane, the temperature of air sent form an air outlet opening is lower, the down-hole temperature is effectively reduced, so as to cause the down-hole operators to feel comfortable, and the difficulty of the down-hole high temperature is greatly released.
Description
Technical field:
The utility model relates to the air duct of air-supply under a kind of mine.
Background technology:
For guaranteeing downhole safety production, each mine main all is necessary for the down-hole air-supply, and promptly the air duct that connects together by blower fan and some joints is delivered to the down-hole with fresh air.Down-hole a kind of air duct commonly used comprises circular cylindrical shell and connecting ring at present, and cylindrical shell is made by airfast flexible material, be generally plastic coat cloth, two ends of cylindrical shell are tightly connected with connecting ring respectively, the connecting ring equal diameters of two ends, and connecting ring diameter and barrel diameter equate.Air duct typically have a diameter from 600 or 800 millimeters, length is 10 meter one joint.During use, the connecting ring of air duct one end is clamp-oned tension then in another air duct sideling, two connecting rings are buckled together make two air ducts connections, so operation links to each other a plurality of air ducts, constitutes length apart from air supply duct.Though this air duct is simple in structure, easy to connect, it is reliable to use, the temperature of air is subjected to ectocine bigger in the tube, and from the air that the work plane air outlet is sent, its temperature is subjected to the influence of tunnel high temperature, and is basic identical with downhole temperature.And down-hole high temperature is the difficult problem of puzzlement manufacturing enterprise always, is difficult to so far solve.
Summary of the invention:
The purpose of this utility model be design a kind of be subjected to externally temperature influence less, make the lower insulation air duct of air themperature of delivering to the down-hole.
The realization the technical solution of the utility model is, a kind of insulation air duct, comprise circular cylindrical shell and connecting ring, cylindrical shell is made by airfast flexible material, and two ends of cylindrical shell are tightly connected with connecting ring respectively, it is characterized in that, cylindrical shell is outside equipped with the insulation sleeve, insulation sleeve two ends also are tightly connected with the connecting ring of two ends respectively, and cylindrical shell is provided with at least one air vent, and the space between cylindrical shell and the insulation sleeve constitutes insulation layer.
The utility model has the advantages that, air duct is when air-supply, the air that certain pressure arranged in the cylindrical shell enters insulation layer between cylindrical shell and the insulation sleeve by air vent, and air has good heat preservation and insulation, thereby, when air flows in air duct, substantially be not subjected to the temperatures involved in the tunnel, the air themperature of sending from air outlet is lower, effectively reduces downhole temperature, make the downhole operations workman feel more comfortable, solved the insoluble difficult problem of down-hole high temperature substantially.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Number in the figure: 1 cylindrical shell, 2 insulation sleeves, 3 connecting rings, 4 air vents, 5 insulation layers.
The specific embodiment:
Referring to Fig. 1, Fig. 2, described insulation sleeve 2 is made by airfast flexible material, and airfast flexible material can be a plastic coat cloth.Described air vent 4 is 4, and diameter is 12 millimeters; The position of air vent 4 is arranged near connecting ring 3 places, is the 120-300 millimeter apart from connecting ring 3 usually; For guaranteeing the intensity of cylindrical shell 1, should be pressed with tubular rivet on the air vent 4.Air duct should make cylindrical shell 1 have an end of air inlet 4 when mounted, is positioned at air intake, be that air flows to the other end that does not have air vent from the end that air vent 4 is arranged, enter next air duct again, can make more sufficient that air in the insulation layer 5 fill like this, better heat preservation.
