[0021] Please see Figures 1-4 As shown, this utility model is a spray exhaust gas filtration device, including a filter box 1 and an exhaust fan 3. A through hole 2 is formed on the upper surface of the filter box 1. The exhaust fan 3 is installed on the upper surface of the through hole 2. Mounting blocks 101 are welded to the inner periphery of the filter box 1. Guide holes 102 are formed on one surface of each of the four mounting blocks 101. Guide rods 103 are slidably installed inside each of the four guide holes 102. A door 104 is welded to one end of each of the four guide rods 103. A first mounting frame 105 is welded to one surface of the door 104. Positioning grooves 108 are provided at both ends of the upper surface of 105. Each positioning groove 108 has a snap-fit block 109 inside. A filter frame 110 is welded between the two snap-fit blocks 109. Two partition plates 111 are welded crosswise inside the filter frame 110. Filter cotton 112 is filled between the partition plates 111 and the filter frame 110, which makes it convenient to pull out the filter frame 110 after the filter box 1 has been working for a period of time. The partition setting of the filter frame 110 makes it easy to replace the filter cotton 112, thus improving the convenience of using the device.
[0022] A second mounting frame 106 is welded to the lower surface of the first mounting frame 105. Both the lower surfaces of the first mounting frame 105 and the second mounting frame 106 are welded with a breathable mesh 107. The interior of the second mounting frame 106 is filled with activated carbon 113 to perform secondary filtration of the spraying exhaust gas and improve the filtration effect when the device is in use.
[0023] A handle 115 is welded to the other surface of the door 104. An exhaust pipe 116 is installed on one surface of the filter box 1. The exhaust pipe 116 is located below the second mounting frame 106. One end of the exhaust pipe 116 extends to the outside of the filter box 1. Two slide rails 114 are welded to the two opposite surfaces inside the filter box 1. The positions of the four slide rails 114 correspond to the positions of the first mounting frame 105 and the second mounting frame 106, respectively.
[0024] The first mounting frame 105 and the second mounting frame 106 are slidably connected to the slide rail 114. The exhaust fan 3 includes a fan housing 301 and a receiving plate 303. Threaded holes are opened on the upper and lower surfaces of the fan housing 301, and mounting bolts 302 are installed in the threaded holes.
[0025] The lower ends of the four mounting bolts 302 are screwed and fixed to the upper surface of the filter box 1. The support plate 303 is welded to the lower surface of the fan housing 301. The drive motor is fixedly installed on the upper surface of the support plate 303. The fan blade 304 is installed at the output end of the drive motor.
[0026] Please see Figures 1-4 As shown, this utility model is a spraying exhaust gas filtration device. Its usage method is as follows: First, move the filter box 1 to the spraying location. During the spraying process, start the drive motor to drive the fan blade 304 to rotate rapidly. When the fan blade 304 rotates, it draws the spraying exhaust gas in the air into the filter box 1. When the spraying exhaust gas moves downward, it is first intercepted by the filter cotton 112, which adsorbs the particulate matter in the spraying exhaust gas. Then, the remaining gas passes through the filter cotton 112 to reach the activated carbon 113, where it undergoes secondary filtration. Finally, it is discharged through the exhaust pipe 116. After the filter box 1 has been working for a period of time, pull the handle 115 to pull out the first mounting frame 105 and the filter frame 110. The separation setting of the filter frame 110 facilitates the replacement of the filter cotton 112, improving the convenience of using the device.
