Abstract
The utility model discloses a kind of muffler applied to large-scale vacuum tank, muffling bucket top removably connects air inlet bucket；Air inlet bucket circumferential wall is equipped with hole group；Top of the air inlet bucket far from muffling bucket removably connects top cover by threaded rod, and muffling bucket is partitioned into the quieter material filled cavity on top and the air cavity of lower part；Escape pipe is exported from air cavity；Muffler provided by the utility model applied to large-scale vacuum tank, top cover play preliminary noise buffer action, and air stream is divided into shallow bid air stream by the hole group of air inlet bucket, reduces the generation of noise；Noise is greatly reduced under the action of into quieter material of the shallow bid air stream in muffling bucket in quieter material filled cavity, while air pressure declines；Quieter material in quieter material filled cavity also has the function of filtering air plankton simultaneously.
Description
Technical field
The utility model relates to muffler field more particularly to a kind of mufflers applied to large-scale vacuum tank.
Background technique
The large-scale vacuum tank class equipment that often will use in factory is in vacuum, and only exhaust fan can generate noise,
The noise of exhaust fan is generally little.And in putting vacuum process, if sucking air directly from free atmosphere can generate very greatly
Noise, while suck gas flow rate it is very big, certain damage is generated to equipment.Especially when being mixed with solid granulates in atmosphere
When, in putting vacuum suck gas process, since the presence of solid granulates causes bigger damage to vacuum tank class equipment.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of disappearing applied to large-scale vacuum tank
Sound device, the technical solution are achieved in that
A kind of muffler applied to large-scale vacuum tank, including muffling bucket, air inlet bucket, top cover, escape pipe.
The muffling bucket top removably connects air inlet bucket, and muffling bucket and air inlet bucket connection.The air inlet bucket circumference
Wall is equipped with hole group.
Top of the air inlet bucket far from muffling bucket removably connects top cover by threaded rod, and the top cover covers completely
Air inlet bucket and with muffling bucket arranged superposed 100-200mm, the inner diameter of top cover 100- big compared with the outer diameter of muffling bucket
200mm。
The muffling bucket is partitioned into the quieter material filled cavity on top and the air cavity of lower part, the partition be with
The porous plate of venthole.The escape pipe is exported from air cavity.
During vacuum tank puts vacuum, gap of the air between muffling bucket and top cover enters, and passes through air inlet bucket；It is empty
Air-flow is divided into shallow bid air stream by the hole group of air inlet bucket, and top cover is as noise buffer action at this time；Into in muffling bucket
Quieter material of the shallow bid air stream in quieter material filled cavity under the action of noise be greatly reduced, while air pressure declines；It is small
Stock air stream is subsequently passed through partition, into air cavity, enters vacuum tank finally by escape pipe.
Preferably, the diameter of described hole is 20-50mm.
Preferably, the described hole group gross area accounts for the 40-60% of air inlet bucket circumferential wall area.
Optionally, the muffling bucket top removably connects air inlet bucket by stud.
Preferably, the diameter of the venthole is 20-50mm, and the venthole gross area accounts for porous plate partition area
40-60%.
Muffler provided by the utility model applied to large-scale vacuum tank, top cover play preliminary noise buffer action, air
Stream is divided into shallow bid air stream by the hole group of air inlet bucket, reduces the generation of noise；Into the shallow bid air in muffling bucket
Noise is greatly reduced under the action of flowing the quieter material in quieter material filled cavity, while air pressure declines；Quieter material filling
Quieter material in chamber also has the function of filtering air plankton simultaneously.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and detailed description；
Fig. 1 is the muffler overall schematic that the utility model is applied to large-scale vacuum tank.
Fig. 2 is the muffler sectional view that the utility model is applied to large-scale vacuum tank.
Fig. 3 is the utility model partition schematic diagram.
Appended drawing reference: 1- muffling bucket, 11- quieter material filled cavity, 12- partition, 121- venthole, 13- air cavity, 2- air inlet
Bucket, 21- hole, 22- threaded rod, 3- top cover, 4- escape pipe.
Specific embodiment
As shown in Figure 1-3, a kind of revealed muffler applied to large-scale vacuum tank of the utility model, including muffling bucket
1, air inlet bucket 2, top cover 3, escape pipe 4.
1 top of muffling bucket removably connects air inlet bucket 2, and muffling bucket 1 and air inlet bucket 2 by stud (not shown)
It is logical.2 circumferential wall of air inlet bucket is equipped with 21 group of hole.
Air inlet bucket 2 far from muffling bucket 1 top by threaded rod 22 removably connection top cover 3, top cover 3 cover completely into
Gas bucket 2 and with 1 arranged superposed 100-200mm of muffling bucket, the big 100- of outer diameter of the inner diameter of top cover 3 compared with muffling bucket 1
200mm。
Muffling bucket 1 is divided into the quieter material filled cavity 11 on top and the air cavity 13 of lower part by partition 12, and partition 12 is tool
There is the porous plate of venthole 121.Escape pipe 4 is exported from air cavity 13.
During vacuum tank puts vacuum, gap of the air between muffling bucket 1 and top cover 3 enters, and passes through air inlet bucket
2；Air stream is divided into shallow bid air stream by 21 group of hole of air inlet bucket 2, and top cover 3 is used as noise buffer action at this time；Into
Noise substantially drops under the action of quieter material (not shown) in quieter material filled cavity 11 of shallow bid air stream in muffling bucket 1
It is low, while air pressure declines；Shallow bid air stream is subsequently passed through partition 12, into air cavity 13, enters vacuum finally by escape pipe 4
Tank.
In specific implementation, the diameter of hole 21 is 20mm, and 21 group's gross area of hole accounts for 2 circumferential wall area of air inlet bucket
50%.
In specific implementation, the diameter of venthole 121 is 20mm, and 121 gross area of venthole accounts for 12 area of porous plate partition
50%.
Embodiment is only one embodiment of the utility model, for those of ordinary skill in the art, is not being paid
Under the premise of creative labor, other embodiments can also be obtained with reference to the accompanying drawings, also within protection scope of the present invention.
