DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0032] This embodiment relates to a high-efficiency air supply port using a swirl plate, comprising: an air inlet flange 1, a box body 2, and a liquid tank high-efficiency filter 3. The air inlet flange 1 is fixed to the upper side of the box body 2; the position on the upper side of the box body 2 corresponding to the air inlet flange 1 is hollow; thus, external air can enter the box body 2 through the air inlet flange 1.

[0033] like Figure 1-Figure 6 As shown, it also includes: a filter support frame 5. The liquid tank high efficiency filter 3 is located at the lower end of the box body 2; the upper frame of the filter support frame 5 is inserted into the liquid tank 7 of the liquid tank high efficiency filter 3 at the bent part; the liquid tank 7 is filled with a sealing liquid; the outer diameter of the filter support frame 5 is larger than the outer diameter of the box body 2; the lower end of the box body 2 is welded to the upper frame of the filter support frame 5. By providing the filter support frame 5, the upper frame of the filter support frame 5 is inserted into the liquid tank 7 of the liquid tank high efficiency filter 3 at the bent part, and the lower end of the box body 2 is welded to the upper frame of the filter support frame 5, so that the sealing is completed, the sealing effect is more excellent, and the box body 2 does not contact the sealing liquid in the liquid tank 7, so that the service life of the box body 2 is longer.

[0034] In this embodiment, it also includes: a swirl diffuser plate 4. The swirl diffuser plate 4 is fixed below the filter support frame 5. After the high-efficiency air supply port using the swirl plate is installed, the swirl diffuser plate 4 is flush with the top plate surface in the clean room. The swirl diffuser plate 4 is fixed below the filter support frame 5 by bolts. Figure 6 , Figure 8 , Fig. 9As shown, the swirl diffuser plate 4 includes: a rectangular plate body 17 fixed below the filter support frame 5; a plurality of radially arranged air outlet slots 18 are dug on the rectangular plate body 17; a rotating louver 19 is fixed obliquely on one side of the air outlet slot 18 along the radial direction; the rotating louver 19 faces the outside of the rectangular plate body 17; and the rotating louver 19 forms an acute angle with the surface where the air outlet slot 18 is located. The air passes through the high-efficiency air supply port using the swirl plate, and then is guided by the rotating louver 19 of the swirl diffuser plate 4 to form a jet in the tangential direction. The air supply of the high-efficiency air supply port using the swirl plate generates a typhoon-like vortex under the action of multiple jets. The central area of ​​the vortex forms a negative pressure area, which induces the surrounding indoor air to quickly mix with the supply air. The wind speed is high and the vertical distance of delivery is long, ensuring that the air flow in the room is uniform and there is no dead corner.

[0035] Preferably, the air outlet slots 18 are evenly distributed. In this embodiment, the swirl diffuser plate 4 is formed by bending a stainless steel 304 sanded plate, and bolt holes 20 are provided at four corners of the rectangular plate body 17 .

[0036] In another preferred embodiment of this embodiment, Figure 6 and Figure 7 As shown, in this embodiment, the high-efficiency air supply outlet using a swirl plate also includes: an annular smoke pipe 8 arranged in the box body 2 and located at the lower side of the air inlet flange 1, and a plurality of small holes are evenly opened on the side of the annular smoke pipe 8 facing the liquid tank high-efficiency filter 3, so that when performing the PAO test, the smoke is more uniform and the test result is more accurate.

[0037] like Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the high-efficiency air supply outlet using a swirl plate also includes: two pagoda joints 9 that are passed through the upper frame of the filter support frame 5 and are located on the outside of the box body 2; an injection pipe 10 that is passed through the side of the box body 2 and is connected to the upper end of one pagoda joint 9 at one end and is connected to the annular smoke pipe 8 at the other end; a detection tube 11 that is passed through the side of the box body 2 and is connected to the upper end of another pagoda joint 9 at one end and is open at the other end and is located on the lower side of the annular smoke pipe 8; and two silicone sleeves 12 that are respectively sleeved on the lower ends of the injection tube 10 and the detection tube 11. By providing an injection tube 10 and a detection tube 11, and the lower ends of the injection tube 10 and the detection tube 11 are respectively connected to the upper end of a pagoda joint 9, the high-efficiency air supply outlet using a swirl plate is easier to perform PAO testing. During testing, the silicone sleeve 12 is unplugged, the lower end of the pagoda joint 9 connected to the injection tube 10 is used to connect the PAO dust generator, and the lower end of the pagoda joint 9 connected to the detection tube 11 is used for detection using an aerosol photometer.

[0038] Specifically, Figure 4 and Figure 7As shown, an annular protrusion 13 is provided at the upper end of the pagoda joint 9, so that the upper end of the pagoda joint 9 is fully welded with the lower ends of the injection pipe 10 and the detection pipe 11, thereby greatly improving its sealing performance; a concave-convex stripe 14 is provided at the lower end of the pagoda joint 9, so that the lower end of the pagoda joint 9 is interference fit with the silicone sleeve 12, thereby greatly improving its sealing performance.

The flow equalizer 6 is connected and fixed to the inner side of the top plate of the box body 2 by bolts and a threaded seat welded on the inner side of the top plate of the box body 2. The flow equalizer 6 has evenly distributed air outlet holes. The air entering the box body 2 through the air inlet flange 1 can enter the box body 2 more smoothly after being blocked and buffered by the flow equalizer 6, and flow to the liquid tank high efficiency filter 3, which not only ensures the stability of the airflow, but also effectively protects the liquid tank high efficiency filter 3.

[0040] In another preferred embodiment of this embodiment, Figure 3 As shown, the high-efficiency air supply port using the swirl plate also includes: a plurality of filter pressing pieces 15; the filter pressing piece 15 is connected and fixed to the filter support frame 5 through a screw rod and a nut and a threaded seat welded on the lower side of the filter support frame 5, and the liquid tank high-efficiency filter 3 is fastened to the filter pressing piece 15; the liquid tank high-efficiency filter 3 in the high-efficiency air supply port using the swirl plate is replaceable. When replacing, first remove the swirl diffuser plate 4, then remove the filter pressing piece 15, and then the liquid tank high-efficiency filter 3 can be replaced.

[0043] The working principle of the present invention is roughly as follows: a filter support frame 5 is provided, and the bending part of the upper frame of the filter support frame 5 is inserted into the liquid tank 7 of the liquid tank high-efficiency filter 3, and the lower end of the box body 2 is welded to the upper frame of the filter support frame 5 to complete the sealing, and the sealing effect is more outstanding, and the box body 2 is not in contact with the sealing liquid in the liquid tank 7, so that the service life of the box body 2 is longer; and a swirl type diffuser plate 4 is provided. Different from the traditional diffuser plate, the swirl type diffuser plate 4 utilizes the rotation of the outlet air to send the air in a spiral shape, thereby generating a relatively high induction ratio, so that the supply air is quickly mixed with the surrounding air, the wind speed is large, and the vertical distance of the delivery is long, thereby ensuring that the air flow in the room is uniform and there is no dead corner.

[0044] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
