Abstract
The utility model discloses a silencing assembly capable of meeting the requirements for large-flow air intake and large-flow air exhaust. The silencing assembly capable of meeting the requirements for large-flow air intake and large-flow air exhaust comprises an annular cavity. Silencing ring plates are distributed in the annular cavity in an intersecting inclined staggered mode. One end of each silencing ring plate is fixed to the inner wall of one side of the annular cavity and a gap where air circulates is reserved between the other end of each silencing ring plate and the inner wall of the other side of the annular cavity. Air flow channels are formed between the silencing ring plates. One of every two adjacent silencing ring plates is fixed to the inner wall of the inner side of the annular cavity and the other one is fixed to the inner wall of the outer side of the annular cavity. Air intake holes are formed in the side wall of the outer side of one end of the annular cavity and air exhaust holes are distributed in the side wall of the inner side of the other end of the annular cavity. The silencing assembly capable of meeting the requirements for large-flow air intake and large-flow air exhaust is reasonable in structural design and is placed in a shell and out of a filter element of an air filter when used. Large-flow air entering the air filter is silenced and then enters the filter element of the air filter to be filtered, and therefore the better filter effect on the air can be achieved. The noise of the large-flow air which is filtered is low, and therefore normal work of a following-up air compressor is guaranteed.
Description
Technical field
The utility model relates to a kind of silencer, relates in particular to a kind of noise reduction assembly that can meet the requirement of large flow turnover gas.
Background technique
Existing air filtering device structure, in use its suction port is smaller, can not meet the requirement of large flow turnover gas, its filter process is directly filtered by filter core simultaneously, the inflow noise of large flow is larger, there is no corresponding silencer, and directly filters, noise of air after filtration is larger, affects the normal operation of follow-up air compressor.
The model utility content
The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of noise reduction assembly that can meet the requirement of large flow turnover gas is provided.
The utility model is achieved through the following technical solutions:
A kind of noise reduction assembly that can meet the requirement of large flow turnover gas, include annular housing, it is characterized in that: be distributed with the noise reduction ring flat-plate that intersection tilts to misplace in described annular housing, one end of described noise reduction ring flat-plate is fixed on the inwall of annular housing one side, leave the gap for circulation of air between the inwall of the other end and annular housing opposite side, form air communication channel between described noise reduction ring flat-plate, and in adjacent noise reduction ring flat-plate one is fixed on the inwall of annular housing inboard, another is fixed on the inwall in the annular housing outside, be distributed with inlet hole on the sidewall in the described annular housing one end outside, be distributed with air outlet hole on the sidewall of the inboard of the other end.
The utility model has the advantages that:
The utility model reasonable in design, during use, be placed in air filter housing, outside filter core, by being distributed with the structure of the noise reduction ring flat-plate that intersects to tilt to misplace in annular housing, the mass flow air entered is carried out to noise reduction, and then enter filter element filtering, can reach better filtering effect, the mass flow air noise after filtration is smaller, guarantees the normal operation of follow-up air compressor.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of noise reduction assembly that can meet the requirement of large flow turnover gas, include annular housing 1, be distributed with the noise reduction ring flat-plate 2 that intersection tilts to misplace in annular housing 1, one end of noise reduction ring flat-plate 2 is fixed on the inwall of annular housing 1 one sides, leave the gap for circulation of air between the inwall of the other end and annular housing 1 opposite side, form air communication channel 3 between noise reduction ring flat-plate 2, and in adjacent noise reduction ring flat-plate 2 one is fixed on the inwall of annular housing 1 inboard, another is fixed on the inwall in annular housing 1 outside, be distributed with inlet hole 4 on the sidewall in the annular housing 1 one end outsides, be distributed with air outlet hole 5 on the sidewall of the inboard of the other end.
Claims (1)
1. one kind can meet the noise reduction assembly that large flow passes in and out the gas requirement, include annular housing, it is characterized in that: be distributed with the noise reduction ring flat-plate that intersection tilts to misplace in described annular housing, one end of described noise reduction ring flat-plate is fixed on the inwall of annular housing one side, leave the gap for circulation of air between the inwall of the other end and annular housing opposite side, form air communication channel between described noise reduction ring flat-plate, and in adjacent noise reduction ring flat-plate one is fixed on the inwall of annular housing inboard, another is fixed on the inwall in the annular housing outside, be distributed with inlet hole on the sidewall in the described annular housing one end outside, be distributed with air outlet hole on the sidewall of the inboard of the other end.
