Abstract
The utility model discloses an air curtain pipe which comprises a main body; the main body is internally provided with an air inflow channel which penetrates through the main body and an air outlet which is used for jetting air outwards; the main body is also internally provided with a plurality of buffer chambers; and the buffer chambers are communicated with the air inflow channel and connected with air distribution channels which are distributed along the air outlet. In the air curtain pipe, the main body is internally provided with the plurality of buffer chambers, so that air enters the air distribution channels from the buffer chambers and then is jetted out from the air outlet to form an air curtain; and gas enters the air distribution channels from the buffer chambers to ensure that the jetting of the gas is uniform. By means of the buffer chambers which are communicated with the air inflow channel, the gas uniformly enters the air distribution channels through the buffer action of the buffer chambers; and by means of the air distribution channels which are distributed along the air outlet, and the narrow air outlet, the uniform air curtain is formed. The air curtain pipe is rapid in air inflow, uniform in air curtain and good in dust removal and isolation effects.
Description
Technical field
The utility model relates to the air curtain cleaning device, relates in particular to the air curtain tube that a kind of air curtain cleaning device is used.
Background technology
Air curtain tube is widely used in cleaner or the water removal device, forms air curtain, is used to blow afloat drying or blows afloat cooling, and all kinds of corrupt practices creep in for traditional air blowing application product, as: the air-flow that blows out is inhomogeneous; Compressed air consumption is very big; Impact force is powerful, but noise level is too high, has a strong impact on site operation personnel's health.
At present, air curtain tube equipment is applied to mine with in the survival capsule, is used for dedusting and isolates pernicious gas, because the air-flow that air curtain tube blows out is inhomogeneous, can cause the dedusting isolation effect to be had a greatly reduced quality; Because in the survival capsule, the compressed air of storage is limited, the big air curtain tube of air consumption is not by preferential employing; And during urgent danger prevention; Fire damp concentration maybe be too high, and for preventing to produce electric spark, the use of electric energy is restricted; In order to save the energy and the safety that guarantees personnel in the cabin, survival capsule should adopt the air curtain tube device that air consumption is little and do not use electric energy to drive under the mine.
Summary of the invention
The utility model technical problem to be solved is: provide a kind of air consumption little, jet uniform air curtain tube device.
For solving the problems of the technologies described above; The technical scheme of the utility model is: air curtain tube; Comprise main body, said body interior is provided with air flow channel that runs through said main body and the gas outlet that is used for outside injection air, and said body interior also is provided with several surge chambers; Said surge chamber is communicated with said air flow channel, and said surge chamber is connected with the gas distribution passage that distributes along said gas outlet.
As a kind of improvement, be provided with the multilayer step that distributes towards said gas distribution passage in the said surge chamber.
As a kind of improvement, said main body comprises first halfbody and second halfbody, and said gas outlet and gas distribution passage are spliced up and down by said first halfbody and second halfbody.
As a kind of improvement, it is inner that said air flow channel is arranged on said second halfbody.
Compare with air curtain tube device of the prior art, the utility model is provided with several surge chambers in main body, makes air get into gas distribution passage and the ejection from the gas outlet by surge chamber, forms air curtain, and gas gets into the gas distribution passage through surge chamber, and gas is sprayed evenly; Existing air curtain tube device, the gas inflow chamber that has in body interior has occupied most of space of body interior, and air gets into the gas inflow chamber and is sprayed by the gas outlet; Air consumption is big; Jet inhomogeneous, the utility model is owing to have the surge chamber that is communicated with the air flow channel, and gas gets into the gas distribution passage through surge chamber; Through the cushioning effect of surge chamber, gas evenly gets into the gas distribution passage; Owing to have the gas distribution passage of distribution and narrow gas outlet along the gas outlet, form the jet even and enough big air curtain of pressure, the utility model, air inlet is fast, and air curtain is even, and the dedusting isolation effect is good.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the cross sectional representation that the utility model is positioned at the surge chamber place;
Fig. 3 is the structural representation of second halfbody among Fig. 2;
Among the figure: 11-first halfbody; 12-second halfbody; 2-air flow channel; The 3-surge chamber; 4-gas distribution passage; The 5-gas outlet.
The specific embodiment
Shown in Fig. 1, Fig. 2 and Fig. 3 are common; Air curtain tube comprises main body, and said main body comprises first halfbody 11 and second halfbody 12; Said body interior is provided with air flow channel 2 that runs through said main body and the gas outlet 5 that is used for outside injection air; Said body interior also is provided with several surge chambers 3, and said surge chamber 3 is communicated with said air flow channel 2, and said surge chamber 3 is connected with the gas distribution passage 4 that distributes along said gas outlet 5.Said gas outlet 5 is spliced up and down by said first halfbody 11 and second halfbody 12 with gas distribution passage 4.
Be provided with the multilayer step that distributes towards said gas distribution passage in the said surge chamber 3; In the bigger air entering surge chamber 3 of pressure, that passes through the multilayer step stops that the pressure of air diminishes; Even air is got in the gas distribution passage 4, even by the air curtain of gas outlet 5 ejections like this.
Said air flow channel 2 is arranged on said second halfbody 12 inside; Air is connected to an end of air flow channel 2 through pipeline, and other end sealing makes air pass through air flow channel 2 and gets into surge chambers 3; Flowing in the gas distribution passage 4 by surge chamber 3; And, forming air curtain through gas outlet 5 ejections, the direction that air flows is shown in arrow among the figure.
Compare with air curtain tube device of the prior art, the utility model is provided with several surge chambers in main body, makes air get into gas distribution passage and the ejection from the gas outlet by surge chamber, forms air curtain, and gas gets into the gas distribution passage through surge chamber, and gas is sprayed evenly; Existing air curtain tube device, the gas inflow chamber that has in body interior has occupied most of space of body interior, and air gets into the gas inflow chamber and is sprayed by the gas outlet; Air consumption is big; Jet inhomogeneous, the utility model is owing to have the surge chamber that is communicated with the air flow channel, and gas gets into the gas distribution passage through surge chamber; Through the cushioning effect of surge chamber, gas evenly gets into the gas distribution passage; Owing to have the gas distribution passage of distribution and narrow gas outlet along the gas outlet, form the jet even and enough big air curtain of pressure, the utility model, air inlet is fast, and air curtain is even, and the dedusting isolation effect is good.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
