Abstract
The utility model relates to a foam spray head, which is particularly suitable for a foam dust-removing underground coal mine. The foam spray head comprises a housing formed by a hollow cylindrical body, and the housing is connected with an end cover; the middle part of the end cover on the top of the housing is provided with a nozzle groove with a V-shaped through diameter; the outer wall of the housing is provided with a hexagon-nut-shaped bolt die which is integrally connected with the housing to be convenient for being rotated; and an inlet is provided with outside threads which is facilitate the connection with a jet pipe. The spray head has the advantages of simple structure, even distribution of sprayed foam, no atomization, large diffusion angle, and the like, and has wide practicality.
Description
Technical field
The utility model relates to coal mine machinery, particularly a kind of foam nozzle that is used for dust removing down-hole of coal mine.
Background technology
In progress of coal mining, can produce a large amount of dust, and digging operation is the master operation of producing dirt, its dust-producing amount accounts for more than 80% of total dust, the physical and mental health of serious harm coal miner.Present about 260,000 people of pneumoconiosis patient of China's coal-mine industry, and with annual 5000 people's speed increase, annual nearly 3000 people die from pneumoconiosis, have brought great misery for patient and family thereof.In order to prevent and treat dust, each state has all taked a series of measure, traditional measures such as spray for dust suppression, coal-bed flooding etc.
Foam dust-removing technology is a kind of dedusting technology of emerging development in nearest two, 30 years, and it is few to have water consumption, and characteristics such as efficiency of dust collection height especially have significant dust removing effects to respirable dust.In using, the research of foam dust-removing finds, the key of foam dust-removing technology is how foam better is sprayed on the product dirt pits, as development machine pick place, transfer point, make foam form a closely knit solid, surround dust within the specific limits, make it not to external diffusion, reach the purpose of depositing dust.But also be not specifically designed to the foam nozzle of dedusting at present, even if adopted the foam dust-removing measure, used shower nozzle still is confined to the used shower nozzle of spraying water, the foam skewness that so just causes spraying, atomizing are serious, and measure smaller, cause a large amount of dust from the foam gap, to be escaped away, do not satisfy the requirement of dedusting.
The utility model content
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, and foam sprays evenly, the diffusion angle is big, do not produce atomizing, dependable performance, the foam nozzle that the foam nozzle dust removing down-hole of coal mine that dedusting is used under the mine of good dedusting effect is used.
For achieving the above object, the technical solution of the utility model is: it comprises the housing of the hollow cylinder formation that is connected with the termination lid, the middle part of the termination lid of case top offers the nozzle slot of a V-shaped gap of through diameter, the outer wall of housing is provided with the hex nut shape bolt die that is connected as a single entity and is convenient to rotate with it, and the porch is provided with is convenient to the external screw thread that is connected with jet pipe.
Narrow in the middle of the nozzle slot of described pipe cap case top, two hem widths, two edges of groove are circular arc, the opening degree of depth of groove is greater than the thickness of termination lid.
Advantages such as beneficial effect: nozzle structure is simple, is convenient to installation and removal, and is easy to use, and the foam of ejection has sprinkling evenly, does not form atomizing, and angle of flare is big.Be particularly useful for foam dust-removing under the coal mine, also can be used for other field, as fire-fighting fire extinguishing etc.Has remarkable result for the diffusion that suppresses dust under the coal mine.
Description of drawings
Fig. 1 is structure master's pseudosection of the present utility model;
Fig. 2 is a structure vertical view of the present utility model.
Among the figure: housing-1, termination lid-2, nozzle slot-3, bolt die-4, screw thread-5.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
Foam nozzle of the present utility model, the housing 1 that comprises a hollow cylinder, housing 1 top is connected with termination lid 2, the middle part of termination lid 2 offers the nozzle slot 3 of a V-shaped gap of through diameter, narrow in the middle of the nozzle slot 3, two hem widths, two edges of groove are circular arc, the opening degree of depth of groove is greater than the thickness of termination lid 2.The outer wall of housing 1 is provided with the hex nut shape bolt die 4 that is connected as a single entity and is convenient to rotate with it, and the porch is provided with is convenient to the external screw thread 5 that is connected with jet pipe.
During work, use spanner to block bolt die 4, housing 1 closely is connected with the foam delivery pipeline by external screw thread 5, foam under pressure-driven in pipeline flows into the housing 1 of foam jet shower nozzle, foam stream is after shower nozzle 1 inside is stopped by termination lid 2, and pressure increases, when flowing through nozzle slot 3, pressure is released, since narrow in the middle of the jet hole 3, two hem widths, and the opening degree of depth of groove is greater than the thickness of termination lid 2, so when foam sprayed, it is fan-shaped to external diffusion that foam becomes.
