Description
Technical field
The utility model is related to a kind of mine pneumatic jumbolter mufflers.
Background technology
China is that the maximum country of coal production needs a large amount of digging lane of constructing in coal production process in the world
Road prevents from deforming to roadway surrounding rock reinforce, and construction anchor pole is needed to be reinforced.In order to meet, mine down-hole is explosion-proof to be wanted
It asks, down-hole high pressure air-flow is often used to construct for the pneumatic roof bolter of power source.In order to reduce the noise of jumbolter,
So that it is met underground coal mine and be less than 85 decibels of noise operation standards, needs installation muffler to make an uproar to reduce work in its gas outlet
Sound.Current muffler is mainly made of several sound absorption chambers circuit of shell and internal series-connection, rubs by sound absorption chamber and air-flow
Wiping reduces noise, greasy and moisture influence contained by the gas due to discharge, it is often necessary to muffler is repaired, it is such
Muffler structure is complicated, and manufacturing cost is higher, and it is not convenient enough to repair, time-consuming and laborious, and the greasy moisture being discharged is to well
Lower the working environment of workers also has certain influence.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy to maintenance, time saving and energy saving, lower mine of processing cost
With pneumatic roof bolter muffler.
To achieve the goals above, the utility model includes：Air inlet pipe, fixed cover board, cylindrical shell, sound-absorbing material, work
Dynamic cover board, dismounting hand handle, fixed cover board are fixed at cylindrical shell left end, and air inlet pipe passes through fixed cover board and is fixed at
Cylindrical shell inside center, the air inlet pipe upper end inside cylindrical shell is uniformly provided with several air admission holes, in cylindrical shell
Lower end is uniformly provided with several ventholes, and uniform pack has sound-absorbing material, removable cover around the air inlet pipe inside cylindrical shell
It is screwed in cylindrical shell right end, dismounting hand handle is fixedly installed on the outside of removable cover.
So when in use, the utility model is connected on the exhaust outlet of pneumatic roof bolter, air-flow pass sequentially through into
Tracheae, air admission hole, sound-absorbing material are discharged after cylindrical shell internal refraction, reflection by venthole, due to air admission hole and venthole
Mutually back to setting, sound-absorbing material has around noise-reducing structure, extends effective noise reduction dedusting path of air-flow, improve noise reduction
Dust removing effects disclosure satisfy that underground noise reduction requirement；On the other hand, when needing to overhaul replacement sound-absorbing material using a period of time,
It is easy to open removable cover using dismounting hand handle, the taking-up of useless sound-absorbing material is replaced with new sound-absorbing material, then screw on activity
Cover board.Have the characteristics that simple in structure, easy to maintenance, time saving and energy saving, processing cost is relatively low.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
The A-A sectional views of the structural schematic diagram of Fig. 2 the utility model.
Specific implementation mode
As seen from Figure 1, Figure 2, the utility model includes：Air inlet pipe 2, cylindrical shell 4, sound-absorbing material 5, is lived at fixed cover board 3
Dynamic cover board 6, dismounting hand handle 7.Fixed cover board 3 is fixed at 4 left end of cylindrical shell, is used between fixed cover board and cylindrical shell
The mode of welding is connected and fixed, to ensure intensity and sealing reliability between the two.Air inlet pipe 2 passes through fixed cover board and fixation is set
It sets in 4 inside center of cylindrical shell, the left end of air inlet pipe is air inlet 1, and when use is used for and mine pneumatic jumbolter outlet
Mouth is attached.Air inlet pipe upper end inside cylindrical shell 4 is uniformly provided with several air admission holes 8, in the lower end of cylindrical shell 4
Uniformly it is provided with several ventholes 9, the quantity of air admission hole and venthole is mutually matched with mine pneumatic jumbolter capacity.Cylinder
Uniform pack has sound-absorbing material 5 around the air inlet pipe of enclosure, and removable cover 6 is screwed in 4 right end of cylindrical shell, in removable cover
Outside is fixedly installed dismounting hand handle 7, when needing maintenance to replace sound-absorbing material using a period of time, using dismounting hand handle side
Just removable cover is opened, the taking-up of useless sound-absorbing material is replaced with new sound-absorbing material, then screw on removable cover.
