DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0021] Embodiment: An assembled purification air duct, see Figure 1-Figure 3As shown, it includes an air inlet 1, a dustproof net I3, an air outlet 2, a dustproof net II16 and an activated carbon box 601. The dustproof net I3 is connected to the left side of the air inlet 1, and the dustproof net II16 is connected to the right side of the air outlet 2. The activated carbon box 601 is placed on the left side of the air inlet 1. It also includes an electric push rod 4, a brush 5, a collection box 6 and a controller 17. The electric push rod 4 is connected to the left side of the top of the air inlet 1 by bolts, and the brush 5 is connected to the telescopic rod of the electric push rod 4 by bolts. The brush 5 is in contact with the dust-proof net Ⅰ3, and a collecting box 6 is connected to the lower left side of the air inlet 1 by means of bolts. The upper part of the collecting box 6 penetrates into the air inlet 1 and is located below the dust-proof net Ⅰ3 and the brush 5, so that the impurities brushed off by the brush 5 fall into the collecting box 6. A controller 17 is connected to the left front side of the air inlet 1 by means of bolts. The controller 17 is electrically connected to the electric push rod 4. The telescopic rod of the electric push rod 4 is extended and shortened to make the brush 5 move downward and upward to brush off the impurities on the dust-proof net Ⅰ3.

[0022] See also Figure 1 , Figure 2 and Figure 4 As shown, it also includes an insert block 7, a wedge block 8, a spring I9, a connecting block 10, a guide rod 13, a push rod 12, a spring II 14, a wedge rod 11 and a fixing frame 15. The left side of the air outlet 2 is connected to the insert block 7 distributed front and back by welding. The left side of the insert block 7 is slidably connected to the wedge block 8 distributed up and down. At least one spring I9 is ​​connected between the wedge block 8 and the insert block 7 for auxiliary reset. The right side of the air inlet 1 is connected to the connecting block 10 distributed front and back by welding. The insert block 7 is inserted into the connecting block 10, and the wedge block 8 is clamped with the connecting block 10, so that the insert block 7 is fixed inside the connecting block 10. The left side of the connecting block 10 is connected by welding. There are guide rods 13 distributed up and down, and a push rod 12 is slidably connected to the guide rod 13. The push rod 12 is close to the wedge block 8, and a spring II 14 for auxiliary resetting is sleeved on the guide rod 13. The two ends of the spring II 14 are respectively connected to the connecting block 10 and the push rod 12. A wedge rod 11 is slidably connected to the left side of the connecting block 10, and the wedge rod 11 is in contact with the push rod 12. A fixed frame 15 is connected between the two connecting blocks 10 by welding. Threaded holes are provided on the fixed frame 15, the connecting block 10 and the insert block 7. The push rod 12 is squeezed by pushing the wedge rod 11 to the right, and the push rod 12 moves inward to squeeze the wedge block 8, so that the wedge block 8 moves inward and disengages from the connecting block 10.

[0023] First, the staff places the air outlet 2 on the right side of the air inlet 1, aligns the plug block 7 with the connecting block 10, and then moves the air outlet 2 to the left, so that the plug block 7 is gradually inserted into the connecting block 10. At this time, the wedge block 8 is squeezed inward by the connecting block 10, and the spring Ⅰ9 is compressed accordingly. When the plug block 7 is fully inserted into the connecting block 10, the spring Ⅰ9 returns to its original state, so that the wedge block 8 moves outward and engages with the connecting block 10, and then the plug block 7 is fixed in the connecting block 10, so as to achieve the effect of quickly connecting the air inlet 1 and the air outlet 2. After the connection is completed, the bolts are tightened. The air inlet 1 and the air outlet 2 are connected with the threaded holes of the fixing frame 15, the connecting block 10 and the insert block 7, and then the air inlet 1 and the air outlet 2 are reinforced together to improve the stability of the connection between the air inlet 1 and the air outlet 2. Then the purified air duct is installed at the use point. When the gas enters the air inlet 1, the dustproof net I3 filters the gas, so that the impurities in the gas are intercepted on the dustproof net I3. The filtered gas is filtered twice by the activated carbon box 601. The gas after the secondary filtration enters the air outlet 2, and is filtered again by the dustproof net II 16 before being discharged, thereby achieving The multiple filtering gas effect ensures the gas purification effect. When there are too many impurities on the dustproof net Ⅰ3, the staff turns on the electric push rod 4 through the controller 17 to control the extension and shortening of the telescopic rod of the electric push rod 4, so that the brush 5 moves downward and upward to brush away the impurities on the dustproof net Ⅰ3, thereby achieving the purpose of automatically cleaning the dustproof net Ⅰ3, avoiding the clogging of the dustproof net Ⅰ3 to affect the interception effect of impurities, and also avoiding affecting the gas from entering the air inlet 1. During the cleaning process, the impurities brushed off fall into the collection box 6, so as to facilitate the centralized collection of impurities. When it is necessary to thoroughly clean the air inlet 1 and the air outlet 2, the staff will remove the purification air duct from the point of use, and then push the wedge rod 11 to the right, so that the wedge rod 11 squeezes the push rod 12 to move inward, and the spring II 14 is compressed accordingly, and then the push rod 12 squeezes the wedge block 8 to move inward and disengage the connection block 10, and the spring I9 is ​​compressed accordingly, and then the air outlet 2 is pulled to the right, and the plug block 7 is pulled out from the connection block 10, thereby achieving the effect of quickly disassembling the air inlet 1 and the air outlet 2, and facilitating the cleaning of the air inlet 1 and the air outlet 2.
