Abstract
The utility model relates to an air inflow multi-stage silencing filter for an air compressor. The air inflow multi-stage silencing filter for an air compressor is characterized in that a strainer < 3 >, an inner chamber < 6 > with a two-stage silencing structure for an expansion chamber, a shakeproof ring < 9 > are sealed and fixed in an outer shell < 8 > through a rubber ring washer < 2 >. Thus, a multi-stage silencing structure for the expansion chamber for air filtration is formed. An air inlet < 10 > arranged on the side part of the outer shell < 8 > is composed of a plurality of pores. A U-shaped semi-closed air inlet channel is composed of the outer shell and the inner chamber. Thus, a seal sound insulation structure is formed. The utility model has the advantages of compact structure, low cost, convenient use and maintenance, and very ideal silencing effect.
Description
The utility model relates to a kind of silencer-filter, particularly the air compressor air intake silencer-filter.
Existing air compressor all is furnished with a cover silencing apparatus and a filter cleaner, the cleaning that is used to reduce induction noise and guarantees to enter cylinder air.For the mitigation system cost, conveniently to install and use, usual way is that silencing apparatus and filter cleaner are made of one, and forms noise elimination filtering integrated apparatus.Though existing this device has reached certain requirement, the noise elimination poor effect.
The purpose of this utility model provides a kind of with low cost, and working service is convenient, and the silencer-filter with good noise elimination effect.
The purpose of this utility model is by filter screen and the inner bag with double expansion chamber noise elimination structure, trembleuse cup are sealed and are fixed in the shell with rubber ring pad, form air-filtering, multistage expansion chamber noise elimination structure, to be arranged on the upper lateral part of shell by the suction port that a plurality of holes are formed, make shell and inner bag constitute the semiclosed gas-entered passageway of U-shaped, formation sealing sound insulating structure is realized.Its working procedure is such: air enters the semiclosed gas-entered passageway of U-shaped that is made of housing ［ 8 ］ and inner bag ［ 6 ］ by suction port ［ 10 ］, realize defening effect, realize the noise elimination of one-level expansion chamber through trembleuse cup ［ 9 ］, realize secondary and three grades of expansion chambers noise eliminations through the air inlet catch ［ 7 ］ on inner bag ［ 6 ］ bottom and top again, after the mesopore of filter screen ［ 3 ］ and adpting flange ［ 1 ］ enters air compressor.
The utility model has adopted air-filtering, multistage expansion chamber to eliminate the noise and sealing sound insulation structure combining mode, compact structure not only, and working service is convenient, and the noise elimination effect is desirable especially, has very high popularizing value.
Below in conjunction with embodiment shown in the drawings the utility model is described in more detail.
Adpting flange ［ 1 ］, screw ［ 5 ］ and locating flange ［ 4 ］ fuse filter screen ［ 3 ］, inner bag ［ 6 ］, rubber ring pad ［ 2 ］, and rely on the expansive force of rubber ring pad ［ 2 ］ to be fixed in the shell ［ 8 ］, and the quantity of screw is 6.Trembleuse cup ［ 9 ］ plays a part supporting inner bag ［ 6 ］ and prevents its vibrations, constitutes an expansion chamber jointly with shell ［ 8 ］, inner bag ［ 6 ］ again, plays one-level expansion chamber noise elimination effect.It is 5 millimeters through holes of φ that ring is provided with 6 diameters, and its material can be selected the sound-absorbing material of porous for use, and as spongy rubber, foamed plastics etc. are to increase the effect of resistance noise reduction.It is the through hole of 3 millimeters of φ that the bottom of inner bag ［ 6 ］ or top air inlet catch ［ 7 ］ should have a plurality of diameters, and punching rate is 20～30%, makes inner bag constitute secondary and three grades of expansion chamber noise elimination structures.Suction port ［ 10 ］ can be that the circular hole of 10 millimeters of φ is formed by 6 apertures, and the distance of its central position shrinking away from theshell body top edge is advisable with 20 millimeters.Shell ［ 8 ］ and the available plastics of inner bag ［ 6 ］ or other metallic material, the screw thread on the adpting flange ［ 1 ］ is to be fixed on the air compressor embodiment necessary.
Embodiment specifically is applied to homemade 0.9 cubic metre during with the horizontal air compressor of inner equilibrium formula, and main reference is of a size of: the diameter of inner bag ［ 6 ］ is 54 millimeters of φ, and is high 95 millimeters; Trembleuse cup ［ 9 ］ external diameter is φ 85 millis, and is interior through 45 millimeters of φ; 90 millimeters of housing diameter φ are high 135 millimeters; The distance of the central position shrinking away from theshell body top edge of 6 circular holes of composition suction port ［ 10 ］ is 20 millimeters; 3 millimeters of the former degree of locating flange ［ 4 ］ and adpting flange ［ 1 ］ connect with 6 uniform screws ［ 5 ］.Measured result shows that this embodiment's noise elimination effect is comparatively desirable.
Claims (4)
1, a kind of silencer-filter comprises the filter screen [3] in shell [8] and the shell, it is characterized in that also having in the shell inner bag [6] and trembleuse cup [9], and shell [8] constitutes multistage expansion chamber noise elimination structure jointly with trembleuse cup [9] and inner bag [6].
2, silencer-filter as claimed in claim 1 is characterized in that having on the inner bag upper and lower air inlet catch ［ 7 ］, forms double expansion chamber noise elimination structure.
3, silencer-filter as claimed in claim 1, the suction port ［ 10 ］ that the upper lateral part that it is characterized in that shell has at least two above holes to constitute.
4, silencer-filter as claimed in claim 1 is characterized in that shell and inner bag constitute the semiclosed gas-entered passageway of U-shaped.
