Abstract
The utility model belongs to the technical field of mufflers, and particularly relates to a controllable muffler applicable to a compressed air dryer. The controllable muffler comprises a muffler shell with one end opened, a muffler connector is arranged on one side of the muffler shell, sound absorbing material is filled into an inner cavity of the muffler shell, a lead screw is fixed to the middle of the muffler shell, the outer end portion of the lead screw is sleeved with a multi-hole pressing plate, the inner side face of the multi-hole pressing plate abuts against the sound absorbing material, the outer contour of the multi-hole pressing plate adapts to the inner wall of the muffler shell, an adjusting nut is rotationally arranged on the lead screw, and the multi-hole pressing plate is pressed into the muffler shell by the adjusting nut. According to the controllable muffler applicable to the compressed air dryer, the compression degree of noise elimination sponge can be adjusted by screwing in or screwing out of the adjusting nut, and meanwhile the filling amount of the noise elimination sponge can be increased or decreased according to actual conditions. According to the controllable muffler applicable to the compressed air dryer, a balance point between tail gas noise elimination and discharging speed can be adjusted, and therefore the best effect can be achieved.
Description
Technical field
The utility model belongs to silencing apparatus technical field, is specifically related to a kind of controllable type silencing apparatus that is applicable to compressed-air drier.
Background technique
The silencing apparatus being used on compressed-air drier is mainly dissipative muffler.It is to utilize sound-absorbing porous material to reduce noise, sound-absorbing material is arranged in pipeline to the dissipative muffler forming at the inwall of air-flow path or according to certain way, when sound wave enters, part acoustic energy rubs and changes into thermal energy consumption and fall in the hole of porous material, thereby more to noise elimination effect, according to Diffusion of gas stream principle, mass rate of emission is faster, noise is larger, and compressed-air drier theoretically, The faster the better for exhaust emissions speed, but noise is also larger, at present, the silencing apparatus of numerous domestic manufacturer production is fixed-type substantially, a silencing apparatus is approved product, after using the regular hour, discard or change, in use, acoustical absorptivity is for fixing, can not control as required the balance between noise elimination and exhaust emissions speed.
Summary of the invention
In order to overcome above shortcomings part in prior art, the purpose of this utility model is to provide a kind of and can adjusts exhaust emissions noise and mass rate of emission, is applicable to the controllable type silencing apparatus of compressed-air drier.
In order to reach above-mentioned object, the utility model adopts following concrete technological scheme:
A kind of controllable type silencing apparatus that is applicable to compressed-air drier, the suppressor case that comprises an end opening, one side of suppressor case is provided with silencing apparatus interface, in suppressor case inner chamber, be filled with sound-absorbing material, suppressor case middle part is fixed with a rhizoid bar, the outer end of screw mandrel is arranged with porous pressing plate, the inner side surface of porous pressing plate is against on sound-absorbing material, the external frame of porous pressing plate and the inwall of suppressor case adapt, and an adjusting nut revolves to be located on screw mandrel and by porous pressing plate and is pressed into suppressor case.
Further, described suppressor case is tubular metal shell or the plastic casing of one end sealing, and the middle part of its closed end is provided with described silencing apparatus interface.
Further, described sound-absorbing material is cotton for eliminating the noise.
Compared with prior art, the utlity model has following outstanding advantages and effect:
The utility model can or screw out adjusting nut with precession and adjust the cotton compacted degree of eliminating the noise, and meanwhile, can increase or reduce the cotton loading of eliminating the noise according to truth; The equinoctial point of the adjustable exhaust gas sound-deadening of the utility model and mass rate of emission, to reach optimum efficiency.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of controllable type silencing apparatus that is applicable to compressed-air drier, the suppressor case 2 that comprises an end opening, one side of suppressor case 2 is provided with silencing apparatus interface 1, in suppressor case 2 inner chambers, be filled with sound-absorbing material 3, suppressor case 2 middle parts are fixed with a rhizoid bar 6, the outer end of screw mandrel 6 is arranged with porous pressing plate 4, the inner side surface of porous pressing plate 4 is against on sound-absorbing material 3, the inwall of the external frame of porous pressing plate 4 and suppressor case 2 adapts, and an adjusting nut 5 revolves to be located on screw mandrel 6 and by porous pressing plate 4 and is pressed into suppressor case 2.
Further, described suppressor case 2 is tubular metal shell or the plastic casing of one end sealing, and the middle part of its closed end is provided with described silencing apparatus interface 1.
Further, described sound-absorbing material 3 is cotton for eliminating the noise.
The utility model can or screw out adjusting nut 5 with precession and adjust the cotton compacted degree of eliminating the noise, and meanwhile, can increase or reduce the cotton loading of eliminating the noise according to truth, to obtain the equinoctial point of exhaust gas sound-deadening and mass rate of emission, thereby reaches optimum efficiency.
The all right irregular replacing of this silencing apparatus is eliminated the noise cotton, does not need whole discarding, and Economy is better, and being used on NGFD natural gas filling station special-purpose drying equipment is good selection.
Finally it should be noted that: above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
