Description
Technical field
The utility model belongs to compressor accessory technical field, and in particular to a kind of air inlet noise reduction grid.
Background technology
Compressor is a kind of common equipment, and it is typically provided with grid in inlet channel, for preventing the miscellaneous of outside
Matter enters in compressor, and the grid of conventional art is mainly to be made up of grid bar and the absorption pile layer being arranged on grid bar,
Although it can realize protection effect to a certain extent, its more difficult fixation, and erasure effect is poor, so applicability and
Practicality is restricted.
The content of the invention
The purpose of this utility model is to provide the air inlet noise reduction grid that a kind of structure setting is reasonable and stability in use is good.
The technical scheme for realizing the utility model purpose is a kind of air inlet noise reduction grid, including stainless steel grid housing,
The outer inframe of the stainless steel grid is filled with silencing cotton, and the stainless steel grid housing includes the fixed part at both ends and middle ripple
Line portion, penetrating air-vent is uniformly provided with the side wall of the fixed part and ripple, one on the outer wall of the fixed part
It is body formed to have screens attachment structure.
The screens attachment structure includes screens seat, is fixed on the u-shaped neck of screens seat lateral surface, in the u-shaped neck
Symmetrical inner wall on be equipped with L-type screens block, the turning of the L-type screens block is connected to the inwall of u-shaped neck by rotary shaft
On, compress spring between the side wall of the L-type screens block and the inwall of u-shaped neck.
The thickness of the stainless steel grid housing is 25mm, and the wall thickness of the stainless steel grid housing is 3-5mm.
The distance between adjacent peaks are 20mm in the corrugated part.
The utility model has positive effect：Structure setting of the present utility model is reasonable, and it is used outside stainless steel grid
Frame, it can effectively ensure the stability in use and service life of grid, while inframe is filled with silencing cotton outside stainless steel grid,
Noise can be reduced, while screens attachment structure is fixed with stainless steel grid housing, it is ensured that the stability of installation and
Reliability, strong applicability and practicality are good.
Brief description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model, wherein：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A-A cut-away views in Fig. 1.
Embodiment
(embodiment 1)
Fig. 1 and Fig. 2 shows a kind of embodiment of the present utility model.
Fig. 1 and Fig. 2, a kind of air inlet noise reduction grid, including stainless steel grid housing 1 are seen, in the stainless steel grid housing
Interior to be filled with silencing cotton 2, the stainless steel grid housing includes the fixed part 11 at both ends and middle corrugated part 12, described solid
Determine to be uniformly provided with penetrating air-vent 13 in the side wall of portion and ripple, integrally formed with screens on the outer wall of the fixed part
Attachment structure 3.
The screens attachment structure 3 includes screens seat 31, is fixed on the u-shaped neck 32 of screens seat lateral surface, in the u-shaped
L-type screens block 33 is equipped with the symmetrical inner wall of neck, the turning of the L-type screens block is connected to u-shaped card by rotary shaft 34
On the inwall of groove, spring 35 is compressed between the side wall of the L-type screens block and the inwall of u-shaped neck.When in use, by card
On the fixture block of the position attachment structure screens inlet channel that enters compressor, fixture block is being caught in the width in u-shaped neck due to fixture block
It is fixed with, spring is compressed so can be pressed on L-type screens block and compress, so that L-type screens block is rotated with rotary shaft, so as to
The both ends of L-type screens block is pressed on respectively on the side of fixture block, add and compress fixing point, so as to ensure screens clamping
Stability and reliability.
The thickness of the stainless steel grid housing is 25mm, and the wall thickness of the stainless steel grid housing is 3-5mm.
The distance between adjacent peaks are 20mm in the corrugated part.
Structure setting of the present utility model is reasonable, and it uses stainless steel grid housing, can effectively ensure the use of grid
Stability and service life, while inframe is filled with silencing cotton outside stainless steel grid, can reduce noise, while in stainless steel
Screens attachment structure is fixed with grid housing, it is ensured that the stability and reliability of installation, strong applicability and practicality is good.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need and unable to give all embodiments
It is exhaustive.And these belong to the obvious changes or variations that connotation of the present utility model is extended out and still fall within this practicality
New protection domain.
