Description
Technical field
It the utility model is related to coal mine machinery field, and in particular to a kind of low noise gas diluter.
Background technology
Gas is initial stage of the archaeophyte in accumulation coal-forming, and the action breaks of cellulose and organic matter through anaerobic bacteria form.
High temperature, high pressure environment in, while coal-forming, due to physics and chemical action, continue to generate gas.Gas be it is colourless,
Tasteless gas, but the fragrance of similar apple can be smelt sometimes, this is due to aromatic hydrocarbon gas with gas while gushed
The reason gone out.Gas is 0.554 to the relative density of air, and the density of gas is 0.716kg/m3 in normal conditions, gas
Penetrating power be 1.6 times of air, be insoluble in water, it is not combustion-supporting to maintain to breathe, when reaching finite concentration, can make one because
Anoxic and suffocate, and can occur burn or explode.Gas is with existing for free state and sorption state in coal body or country rock.
The gas diluter that mine uses at present be from the gas diluter of outer buying, because underground coal mine environment is complicated,
Traditional gas diluter crust is relatively thin, it is impossible to which durable in use, service life is shorter.For reduce buying gas diluter into
This, the sound insulation by filling cotton in original pressure ventilation pipe air outlet one end installation cylindrical shroud, shield, but wind regime uses pressure ventilation pipe
Road, very big noise is produced, in order to reduce the noise of gas diluter, a set of pressure-reducing valve is added in pipeline air inlet,
So as to reduce noise result.Pressure wind is produced by pressure ventilation pipe and guides interim hedging chamber inner air flow dilution watt through cylindrical shroud
This.
This product provides a kind of low noise gas diluter, can not only dilute gas, but also can reduce noise, existing
Field energy is convenient to fix, and can also reuse, and is easy to scene hanging to move, has wide market prospects.
The content of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of simple in construction, easy to operate, work and operational efficiency
Height, save resource, the convenient low noise gas diluter installed and reused, for solving the deficiencies in the prior art.
What the technical solution of the utility model was realized in：A kind of low noise gas diluter, including with wind regime air-out
The straight pipe that mouth is connected, described straight pipe are fixedly connected with the first steel cylinder, and the first steel cylinder passes through fixing device and the second steel
Pipe is connected, and Sound-proof material is filled with the first steel cylinder and the second steel pipe, is offered in the end face outside of the second steel pipe ventilative
Hole.
Described fixing device is anchor ear, and the first steel cylinder is connected by anchor ear with the second steel pipe, and straight pipe passes through welding
Mode be connected with the end face outside of the first steel cylinder, the inner side end of the first steel cylinder passes through anchor ear and the medial extremity of the second steel pipe
Face is connected.
The quantity of the second described steel pipe is at least one, the length and diameter of the second steel pipe and the length of the first steel cylinder and
Diameter is equal.
The inner side of described straight pipe is connected with the inside of the first steel cylinder, and straight pipe is fixedly mounted on the outside of the first steel cylinder
The center of end face.
The second described steel pipe and the length of the first steel cylinder are 150mm, and the diameter of the second steel pipe and the first steel cylinder is
89mm。
A diameter of 19 mm of described straight pipe, described straight pipe are to compile tubular structure made of pipe using steel.
The utility model has following good effect：This product is simple in construction, easy to operate, straight pipe and the first steel cylinder
Be fixedly connected, the first steel cylinder is connected by fixing device with the second steel pipe, in the first steel cylinder and the second steel pipe be filled with every
Sound cotton, air-vent is offered in the end face outside of the second steel pipe, simple in construction, easy to assembly, noise is small, can dilute corner
Angle gas, service life length, and Sound-proof material is convenient for changing, improve stability and operability.
