Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-5 .

[0013] A VOC organic treatment equipment exhaust gas collection hood installation structure includes a base plate 1, and further includes: a lifting part 2, which is disposed on the top of the base plate 1; and a fixing part 3, which is disposed on the lifting part 2.

[0014] The lifting unit 2 includes a lifting assembly 21, which is mounted on the top of the base plate 1; and a limiting assembly 22, which is mounted on the lifting assembly 21. The lifting assembly 21 includes two sleeves 211 fixedly connected to the top of the base plate 1. A gear 212 is slidably connected inside each sleeve 211. A top plate 213 is fixedly connected to the top of the two gears 212. An electro-hydraulic push rod 214 is fixedly connected to the top of the base plate 1. The output end of the electro-hydraulic push rod 214 is fixedly connected to the top plate 213. Two support rods 215 are fixedly connected to the top of the base plate 1. A rotating shaft 216 is rotatably connected to the two support rods 215. The device is equipped with a transmission component. Two support rods 215 are symmetrically distributed on both sides of the rotating shaft 216. The limiting component 22 includes a ratchet 221 fixedly connected to the outer wall of the rotating shaft 216. A mounting plate 222 is fixedly connected to the right support rod 215. Two slide rods 223 are slidably connected to the mounting plate 222. Pads 224 are fixedly connected to the top of the two slide rods 223. Each slide rod 223 is provided with an elastic element. The pawls 224 mesh with the ratchet 221. The transmission component includes two gears 217 fixedly connected to the outer wall of the rotating shaft 216. Both gears 217 mesh with two racks 212. The elastic element includes a component wrapped around the two slide rods 223. The outer wall has two springs 225, one end of which is fixedly connected to the mounting plate 222, and the other end of which is fixedly connected to the pawl 224. By setting the lifting part 2, the exhaust gas collection hood 311 can be connected to the VOC organic treatment equipment during use. If its height needs to be adjusted, the electric hydraulic push rod 214 can be activated. The electric hydraulic push rod 214 will cooperate with the two sleeves 211, causing the toothed rod 212 to drive the top plate 213 to slide upward within the two sleeves 211. This setting can expand the collection range of the exhaust gas collection hood 311, thereby improving the exhaust gas collection efficiency. Simultaneously, the electric hydraulic push rod 214, through the two toothed rods 212... When the top plate 213 is raised or lowered by the 12, the two racks 212 will also mesh with the gears 217 on the outer wall of the shaft 216 rotating on the two support rods 215, thereby ensuring the stability of the top plate 213 during the raising and lowering process. In addition, when the shaft 216 rotates, the ratchet 221 on it will mesh with the pawl 224 on the sliding mounting plate 222. As the shaft 216 drives the ratchet 221 to rotate continuously, the pawl 224 can maintain elastic contact with the ratchet 221 with the help of the elastic action of the two slide rods 223 and the outer wall spring 225, thereby preventing the shaft 216 from driving the two gears 217 to reverse, further ensuring the stability after height adjustment.

[0015] The fixing part 3 includes a configuration component 31, which is mounted on the top plate 213; and two fixing components 32, both of which are mounted on the configuration component 31. The configuration component 31 includes an exhaust gas collection hood 311 mounted on the top of the top plate 213. Both the exhaust gas collection hood 311 and the top of the top plate 213 have two fixing holes 312. The fixing component 32 includes a screw 321 slidably connected in the fixing hole 312. The outer wall of the screw 321 has a folding groove 322, and two folding rods 323 are hinged in the folding groove 322. The threaded connection includes a nut 325. A limiting element is provided within the folding groove 322. Two elastic elements are provided on the two folding rods 323. Both folding rods 323 are in contact with the top plate 213. The limiting element includes two stops 324 fixedly connected within the folding groove 322. Each stop 324 is adapted to the two folding rods 323, and the top of each stop 324 is notched. The elastic element includes a telescopic rod 326 fixedly connected to the side of the two folding rods 323 that is close to each other. A spring 327 is wound around the outer wall of the telescopic rod 326. The ends of the springs 327 that are far apart from each other are connected to the two folding rods 323. 23. Fixed connection: By setting the fixing part 3, if it is necessary to install the exhaust gas collection cover 311 and the top plate 213, the fixing holes 312 on the exhaust gas collection cover 311 and the fixing holes 312 on the top plate 213 can be aligned first. After alignment, the screw 321 is inserted into the fixing hole 312. During the insertion process, the two hinged folding rods 323 at the top of the screw 321 will retract inward into the folding grooves 322 on the screw 321 under the action of the extrusion force. When retracting, they will compress the telescopic rod 326 and the second spring 327 on it, so that they accumulate elastic potential energy to provide support for subsequent reset. The retraction mechanism avoids interfering with the penetration of the screw 321. After the screw 321 fully penetrates the fixing hole 312, the two folding rods 323 will unfold against each other under the restoring thrust of the telescopic rod 326 and the second spring 327, limiting the penetration end. Then, use a tool to tighten the nut 325 at the other end of the screw 321 to complete the fixation of the exhaust gas collection cover 311. This setting is simple and quick to operate, enabling the exhaust gas collection cover 311 to be quickly disassembled and assembled. At the same time, the double limiting by the folding rod 323 and the nut 325 ensures the firmness of the connection after installation, effectively preventing loosening and falling off during use.

[0016] VOC organic treatment equipment: These are environmental protection devices designed to treat volatile organic compounds (VOCs). They decompose or recover organic matter in waste gas through technologies such as adsorption, catalytic combustion, and condensation recovery. Common models include RCO-5000 catalytic combustion type, TO-10000 thermal combustion type, and activated carbon adsorption tower-20000 adsorption type.

[0017] It should be noted that the control of the electro-hydraulic push rod 214 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.

[0018] One specific application of this embodiment is as follows: During use, the exhaust gas collection hood 311 can be connected to a VOC organic treatment device. If its height needs to be adjusted, the electric hydraulic push rod 214 can be activated. The electric hydraulic push rod 214 will cooperate with the two sleeves 211, causing the toothed rod 212 to drive the top plate 213 to slide upwards within the two sleeves 211. This arrangement can expand the collection range of the exhaust gas collection hood 311, thereby improving the exhaust gas collection efficiency. Simultaneously, when the electric hydraulic push rod 214 drives the top plate 213 to rise and fall via the two toothed rods 212, the two toothed rods 212 will also rotate on two supports... The outer wall gear 217 of the rotating shaft 216 on the support rod 215 meshes with the shaft shaft 216 to ensure the stability of the top plate 213 during lifting. Furthermore, when the rotating shaft 216 rotates, its ratchet 221 meshes with the pawl 224 on the sliding mounting plate 222. As the rotating shaft 216 drives the ratchet 221 to rotate continuously, the pawl 224 can maintain elastic contact with the ratchet 221 through the elastic action of the two sliding rods 223 and their outer wall spring 225, thereby preventing the rotating shaft 216 from driving the two gears 217 to reverse, further ensuring stability after height adjustment. If it is necessary to remove exhaust gas... To install the collection hood 311 and the top plate 213, first align the fixing holes 312 on the exhaust gas collection hood 311 with the fixing holes 312 on the top plate 213. After alignment, insert the screw 321 into the fixing holes 312. During insertion, the two hinged folding rods 323 at the top of the screw 321 will retract inward into the folding grooves 322 on the screw 321 under the action of extrusion force. During the retraction, the telescopic rod 326 and the second spring 327 on it will be compressed, allowing them to accumulate elastic potential energy to provide support for subsequent reset. The retraction of the two folding rods 323 can prevent damage to the screw 321. The penetration of screw 321 causes interference. After screw 321 fully penetrates the fixing hole 312, the two folding rods 323 will unfold against each other under the restoring thrust of telescopic rod 326 and spring 327, limiting the penetration end. Then, use a tool to tighten the nut 325 at the other end of screw 321 to complete the fixing of exhaust gas collection cover 311. This setting is simple and quick to operate, and can realize the quick installation and removal of exhaust gas collection cover 311. At the same time, the double limiting of folding rod 323 and nut 325 ensures the firmness of the connection after installation and effectively avoids loosening and falling off during use.
