Abstract
The utility model discloses a downhole simple foam generating device and is characterized by comprising a foam generating cavity with a horn mouth. An air duct connecting port is arranged on the end face of the tail portion of the foam generating cavity. A mesh membrane is arranged on the front end face of the horn mouth. Spray nozzles are annularly arranged on the inner side wall of the foam generating cavity. Two input pipes of a negative pressure proportioning mixer are respectively a water supply pipe communicated with a water source, and a drug lead-in pipe communicated with a drug box. A lead-out port of the negative pressure proportioning mixer is arranged on the sidewall portion of the tail portion of the foam generating cavity and is communicated with the spray nozzles. The downhole simple foam generating device is used as a downhole simple fire extinguishing device, and is high in foam expansion, compact in structure, low in manufacturing cost, and convenient to use.
Description
Technical field
The utility model relates to a kind of down-hole quick extinguishing utensil.
Background technology
The generation of mine fire, gently then influence is produced, and is heavy then cause casualties, and burns coal resources and pit gear, therefore carries out the anti-fire extinguishing of mine and be to guarantee the important process of keeping the safety in production.At present the down-hole be directly used in fire extinguishing the utensil kind seldom, generally all use powder fire extinguisher or CO2 fire extinguisher, this appliances also is not suitable for the charging equipment of putting out a fire to save life and property, C class and D class fire, when running into charging equipment, C class and D class fire, can only use foam fire extinguishing system, and large-scale high-expansion foam generator volume is big, the transportation difficulty, be subjected to the restriction in field operation space, can't implement on-the-spot fire extinguishing effectively fast.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of make simple, connect rapidly, coefficient of foaming is high, can effectively implement the simple and easy foam-making apparatus in down-hole of down-hole fire extinguishing fast.
The utility model adopts following technical scheme for the technical solution problem:
The design feature of the simple and easy foam-making apparatus in a kind of down-hole of the utility model is to arrange:
One has bell-mouthed foam generation cavity, the tail end face of described foam generation cavity is provided with duct collar, at described bell-mouthed front end face nethike embrane is set, is distributed with shower nozzle ringwise on the inside wall of described foam generation cavity, the nozzle of described shower nozzle is towards the nethike embrane setting;
One negative pressure proportioner, two input pipes of described negative pressure proportioner are respectively the upper hose that communicates with the water source and the medicament ingress pipe that communicates with chemical tank, the export mouth of described negative pressure proportioner is arranged on the afterbody side wall portion of described foam generation cavity, and is connected with described shower nozzle.
Compared with the prior art, the utility model beneficial effect is embodied in.
The utility model is simple in structure, easy to use, can especially be suitable for the narrow and small work plane occasion of mine away from the fire zone operation in the tunnel; Use the utility model can fast and effeciently implement fire extinguishing in the down-hole.
Description of drawings
Fig. 1 is the utility model structural representation;
Number in the figure: 1 foam generation cavity; 11 horn mouths; 2 nethike embranes; 3 bases; 4 shower nozzles; 5 negative pressure proportioners; 6 duct collar; 7 upper hoses; 8 medicament ingress pipes; 9 chemical tanks.
The specific embodiment
Referring to Fig. 1, the simple and easy foam-making apparatus in down-hole is set in the present embodiment:
The foam generation cavity made from steel pipe 1 that has horn mouth 11 is fixedly installed on the base 3, the tail end face of described foam generation cavity 1 is provided with duct collar 6, front end face at described horn mouth 11 arranges nethike embrane 2, nethike embrane 2 is the coarse cloth of band net, be used for promoting the formation of foam, be distributed with shower nozzle 4 on the inside wall of described foam generation cavity 1 ringwise, the nozzle of described shower nozzle 4 arranges towards nethike embrane 2.
Two input pipes of negative pressure proportioner 5 are respectively the upper hose 7 that communicates with the water source and the medicament ingress pipe 8 that communicates with chemical tank 9, the export mouth of described negative pressure proportioner 5 is arranged on the afterbody side wall portion of described foam generation cavity 1, and is connected with described shower nozzle 4.
During use, the down-hole airduct is connected with duct collar 6, the upper hose 7 of negative pressure proportioner 5 is connected with the mine water source capsule, the medicament ingress pipe 8 of negative pressure proportioner 5 is inserted in the chemical tank 9, foam generation cavity 1 horn mouth 11 is aimed at the fire area, connect the water source and press wind, water and foam mixing liquid namely are sprayed onto on the nethike embrane 2 from shower nozzle 4, under the driving of high-pressure blast, generate high-density foam and a large amount of carbon dioxides, foam has extremely strong stickiness, can cover secluding air on the surface of the thing that catches fire, reach the fire extinguishing effect.
