Detailed Description
In order to make the patent purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Only portions related to the embodiments of the present invention are shown for convenience of explanation.
Combine shown in fig. 1-2, the air curtain device includes transmission end main part 1, the mounting groove 2 that transmission end main part top has been opened to the downside, mounting groove opens the bottom has and runs through the passageway 3 of transmission end main part, the open-top position of passageway still is equipped with window lens 4, install air curtain generator 5 in the mounting groove, coupling 6 is installed to transmission end main part lateral wall, air curtain generator is hollow structure, and the air curtain generator outside upwards evenly opens round air curtain hole 7 inwards to the slant, the coupling terminal with air curtain hole intercommunication.
In the structure, the air curtain device mainly utilizes the air curtain generator to form a cone-shaped air curtain, and the air curtain and the air flow respectively block and reversely blow oppositely floating smoke and dust so as to prevent smoke pollution. The transmitting end main body is mainly used as a carrier of the air curtain device, the transmitting end main body is provided with a mounting groove mainly for mounting the air curtain generator, the air curtain generator is fixed on the transmitting end main body through threaded connection, externally input compressed air flows into a cavity of the transmitting end main body through pipe joints at two ends to form annular air flow, the annular air flow forms a conical air curtain through the air curtain hole, and the air curtain forms single axial air flow after being gathered. The air curtain and the air flow respectively block and back blow the oppositely floating smoke and dust to prevent the smoke and dust pollution. The window lens can enable light beams at the emission end of the dust analyzer to penetrate through, and can prevent smoke powder in the chimney from entering the interior of the emission end of the dust analyzer.
As an optimal structure, the air curtain generator is of a T-shaped structure, a circle of air gap area 8 is arranged on the periphery of the lower portion of the air curtain generator in the transmitting end main body, the air curtain hole is communicated with the air gap area, an air injection groove 9 is further formed in the transmitting end main body, the air injection groove is communicated with the air gap area, and the pipe joint is installed at the outer end of the air injection groove.
