Abstract
The utility model provides a silencer for a vortex vacuum pump. The silencer is cylindrical; one end of the silencer is provided with a pump connection opening and the other end of the silencer is provided with an air exhausting opening; an air inlet is formed in the middle of the pump connection opening; a plurality of circular silencing sheets are arranged inside the silencer in parallel; the silencing sheets are provided with air vents. The silencer disclosed by the utility model is simple in structure, convenient to use, good in silencing effect, small in volume and convenient to detach and maintain, and is suitable for being used for various vacuum pumps.
Description
Technical field
The utility model belongs to field of vacuum, specifically a kind of baffler for scroll vacuum pump.
Background technique
Vacuum pump is that a kind of rotary positive-displacement vacuum pump must have fore pump to cooperate can to use and has larger pumping speed to be contained dust and the insensitive industries such as metallurgy, chemical industry, food, electronics plated film that are widely used in of water vapor in the gas to extracting in wider pressure range.The shortcoming of existing vacuum pump is that noise is too large, does not have a kind of muffling device of vacuum pump special use.
The model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of baffler for scroll vacuum pump.
A kind of baffler for scroll vacuum pump, it is characterized in that described baffler is columniform, one end of described baffler is provided with the pump connection mouth, the other end of described baffler is provided with relief opening, the centre of described pump connection mouth is provided with suction port, the inside of described baffler is arranged with the bloop of some circles in parallel, is provided with exhaust port on the described bloop.
Described a kind of baffler for scroll vacuum pump is characterized in that described bloop distance each other equates.
Described a kind of baffler for scroll vacuum pump is characterized in that described bloop has 6.
Described a kind of baffler for scroll vacuum pump is characterized in that described exhaust port is the ring setting at bloop, forms the annulus of two concentric different radiis.
Described a kind of baffler for scroll vacuum pump is characterized in that each annulus is comprised of 12 evenly distributed exhaust ports respectively, the interlaced setting of the exhaust port of two annulus.
A kind of baffler for scroll vacuum pump of the present utility model does not affect exhaust effect, and is simple in structure, easy to use, good muffling effect, and volume is small and exquisite, and dismounting is easy to maintenance, is fit to various vacuum pumps and uses.
Description of drawings
Fig. 1 is the sectional view of a kind of baffler for scroll vacuum pump of the present utility model;
Fig. 2 is the bloop schematic diagram of a kind of baffler for scroll vacuum pump of the present utility model;
Among the figure, 1-suction port; 2-pump connection mouth; 3-relief opening; 4-bloop; 5-exhaust port.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As depicted in figs. 1 and 2, a kind of baffler for scroll vacuum pump of the present utility model, this baffler is columniform, one end of baffler is provided with the pump connection mouth, the other end of baffler is provided with relief opening, the centre of pump connection mouth is provided with suction port, and the inside of baffler is arranged with the bloop of 6 circles in parallel, is provided with exhaust port on the bloop.Bloop distance each other equates.Exhaust port is the ring setting at bloop, forms the annulus of two concentric different radiis, and each annulus is comprised of 12 evenly distributed exhaust ports respectively, the interlaced setting of the exhaust port of two annulus, and to inside and outside 2 direction exhausts.
During use, baffler is connected with vacuum pump by the pump connection mouth, gas enters baffler from suction port, flows to exhaust ports by the exhaust port on the bloop and discharges, because the particular design of bloop and exhaust port greatly reduces noise.
The above only is preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of doing within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all is included within the protection domain of the present utility model.
