Abstract
The utility model discloses a kind of portable blower conical flow guiding silencing means, it include conically shaped, the miner diameter end of conically shaped is connected with flange, the bigger diameter end of conically shaped is fixedly connected with water conservancy diversion cone cylinder by support plate, the conical outer surface of water conservancy diversion cone cylinder and the cone-shaped inner surface of conically shaped form taper air-inlet cavity, and filter protection net is connected between the bigger diameter end of water conservancy diversion cone cylinder and the bigger diameter end of conically shaped；Circular conical surface, the upper bottom surface of the water conservancy diversion cone cylinder are perforated plate, and the bottom surface of water conservancy diversion cone cylinder is sealing plate, are filled with sound-absorbing material layer in water conservancy diversion cone cylinder.The utility model uses side air inlet mode, prevents dust, coal dust directly front to enter blower, so as to extend the service life of blower, while can preferably play absorbing sound and lowering noise effect.
Description
Technical field
The utility model relates to mining ventilation equipment, particularly belong to a kind of portable blower conical flow guiding silencing means.
Background technique
The guiding device of existing mining ventilation equipment enters blower, and guide shell by guide shell using front air inlet
Taper is smaller, front air inlet, easily sucking dust, coal dust, and after a period of use, guide shell coal dust accumulation is more, both reduces
The service life of blower, is also not achieved original absorbing sound and lowering noise effect.
Utility model content
The purpose of the utility model is to provide a kind of portable blower conical flow guiding silencing means to be prevented using side air inlet mode
Dust, coal dust directly front enter blower, so as to extending the service life of blower, while can preferably play sound-absorbing drop
It makes an uproar effect.
The technical solution of the utility model is as follows:
A kind of portable blower conical flow guiding silencing means, includes conically shaped, and the upper bottom surface of conically shaped is connected with flange, conically shaped
Inner cavity is fixedly connected with water conservancy diversion cone cylinder by support plate, and gap is formed between the outer surface of water conservancy diversion cone cylinder and the inner surface of conically shaped
Taper air-inlet cavity is connected with filter protection net between the bottom surface of water conservancy diversion cone cylinder and the bottom surface of conically shaped；The water conservancy diversion cone cylinder
Barrel, upper bottom surface be respectively perforated plate, the bottom surface of water conservancy diversion cone cylinder is sealing plate, is filled with sound-absorbing material in deflection cone tube inner chamber
Layer.
The sound-absorbing material layer is made of porous attractive material.
The filter protection net is made of rhombus net.
The upper bottom surface of the conically shaped is connected by flange with the silencing means of portable blower.
Gap forms taper air-inlet cavity between the outer surface of water conservancy diversion cone cylinder and the inner surface of conically shaped of the utility model, real
Existing side air inlet mode, filter protection net prevents dust, coal dust directly front to enter in blower, so as to extend blower
Service life, while sound-absorbing material layer is filled in the barrel of water conservancy diversion cone cylinder, the perforated plate of upper bottom surface and inner cavity, it can be more preferable
Play absorbing sound and lowering noise effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Referring to attached drawing, a kind of portable blower conical flow guiding silencing means includes conically shaped 1, and the upper bottom surface 2 of conically shaped 1 connects
There is flange 3, the upper bottom surface 2 of conically shaped 1 is connected by flange 3 with the silencing means of portable blower, and 1 inner cavity of conically shaped passes through support plate
4 are fixedly connected with water conservancy diversion cone cylinder 5, and gap forms taper air-inlet cavity between the outer surface of water conservancy diversion cone cylinder 5 and the inner surface of conically shaped 1
6, filter protection net 8 is connected between the bottom surface 7 of water conservancy diversion cone cylinder 5 and the bottom surface 9 of conically shaped 1, filter protection net 8 is by diamond shape
Net is made；Barrel 10, the upper bottom surface 11 of water conservancy diversion cone cylinder 5 are respectively perforated plate, and the bottom surface 7 of water conservancy diversion cone cylinder 5 is sealing plate, deflection cone
Cylinder is filled with sound-absorbing material layer 12 in 5 inner cavities；Sound-absorbing material layer 12 is made of porous attractive material.
