Abstract
The utility model discloses a mining anchor rope rig muffler, include: the air inlet, the gas outlet, an air inlet pipe, the outlet duct, the cylinder casing, control chamber communicating pipe, left side lumen communicating pipe, the division board, at the internal fixed twice division board that sets up of circular cylindrical shell, make cylinder casing internal partitioning form left side amortization chamber, middle amortization chamber, right side amortization chamber, make left side amortization chamber and right side amortization chamber intercommunication about having penetrated chamber communicating pipe on the division board, it makes left side amortization chamber and middle amortization chamber intercommunication left lumen communicating pipe to have penetrated on the division board, it makes middle amortization chamber and gas outlet intercommunication to have penetrated the outlet duct on the casing in left side amortization chamber, it makes right side amortization chamber and air inlet intercommunication to have penetrated the intake pipe on the casing in right side amortization chamber. Have simple structure, convenient to use, noise cancelling effect characteristics such as good.
Description
Technical field
The utility model belongs to the Noise Prevention and Treatment of mine pneumatic anchor cable rig and noise reduction technical field.
Background technology
China is the country that coal production is maximum in the world, in coal production process, needs a large amount of digging tunnel of constructing, and prevents distortion to carry out reinforcing to roadway surrounding rock, needs construction anchor cable to reinforce.In order to meet mine down-hole requirement of explosion proof, down-hole high pressure air-flow is often adopted to be that the pneumatic anchor cable rig of power source is constructed.In order to reduce the noise of anchor cable rig, making it meet underground coal mine and being less than 85 decibels of noise operation standards, need in its gas outlet exhaust box to be installed to reduce operating noise.Current exhaust box is formed primarily of housing and silencing net, silencing net device is in housing, the friction of silencing net and air-flow is relied on to reduce noise, still higher noise can be sent in actual use, work in such a case for a long time, still can cause certain injury to staff, some meetings cause the symptoms such as slight deafness, headache, affect operative's construction.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, easy to use, the Mine anchorage cable rig exhaust box of good muffling effect.
To achieve these goals, the utility model comprises: air intake opening, gas outlet, draft tube, escape pipe, cylindrical shell, chamber, left and right communicating pipe, left chamber communicating pipe, division board, at cylindrical shell internal fixtion, twice division board is set, cylindrical shell interior separation is made to form left side silencing cavity, middle silencing cavity, right side silencing cavity, division board penetrates and has made left side silencing cavity be communicated with right side silencing cavity chamber, left and right communicating pipe, division board penetrates and has made left side silencing cavity be communicated with middle silencing cavity left chamber communicating pipe, the housing of left side silencing cavity has penetrated escape pipe makes middle silencing cavity be communicated with gas outlet, the housing of right side silencing cavity has penetrated draft tube makes right side silencing cavity be communicated with air intake opening.
So in use, the utility model is fixed on pneumatic anchor cable rig, air intake opening is connected with the gas discharge outlet of pneumatic anchor cable rig, the noise air-flow of now discharging passes through left side silencing cavity, right side silencing cavity, three the roundabout friction buffer noise reductions of middle silencing cavity successively, pneumatic noise is made effectively to reduce, reaching noise can lower than the working environment of 50 decibels, be conducive to workman to construct, physiological damage can not be caused to workman, there is the features such as structure is simple, easy to use, good muffling effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises: air intake opening 1, gas outlet 9, draft tube 2, escape pipe 8, cylindrical shell 3, chamber, left and right communicating pipe 6, left chamber communicating pipe 10, division board 11.Twice division board 11 is set at cylindrical shell 3 internal fixtion, makes cylindrical shell interior separation form left side silencing cavity 7, middle silencing cavity 5, right side silencing cavity 4, three separate intervals of silencing cavity are airtight.Division board penetrates and has made left side silencing cavity 7 be interconnected with right side silencing cavity 4 chamber, left and right communicating pipe 6, division board penetrates and has made left side silencing cavity 7 be communicated with middle silencing cavity 5 left chamber communicating pipe 10, the housing of left side silencing cavity has penetrated escape pipe 8 makes middle silencing cavity 5 be communicated with gas outlet 9, and gas outlet is in underworkings airspace.The housing of right side silencing cavity has penetrated draft tube 2 makes right side silencing cavity 4 be communicated with air intake opening 1, and air intake opening is for connecting the gas discharge outlet of pneumatic anchor cable rig.Draft tube 2, escape pipe 8, cylindrical shell 3, chamber, left and right communicating pipe 6, left chamber communicating pipe 10, division board 11 all adopt metal material processing and fabricating, to meet underground coal mine requirement of explosion proof.Draft tube, escape pipe, chamber, left and right communicating pipe, left chamber communicating pipe internal diameter specification should be consistent, to ensure all even noise reduction of the flowing of gas.The large I of specification of the present utility model makes series of products according to the model of anchor cable rig.
