[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a VOCs waste gas recovery structure of a cyclohexanol ketone device, comprising a bottom plate 1 and a connecting belt 9, a fixing frame 4 is fixedly connected to the top rear side of the bottom plate 1, a driving motor 10 is fixedly connected to the top of the fixing frame 4, an output end of the driving motor 10 passes through the fixing frame 4 and is fixedly connected to a driving pulley 11, a driven pulley 8 is rotatably connected to the bottom of the fixing frame 4, the driven pulley 8 is connected to the driving pulley 11 through the connecting belt 9, a fan blade 18 is installed at the bottom of the driven pulley 8, and the driving pulley 11 A worm 12 is fixedly connected to the bottom, a worm wheel 13 is meshedly connected to the front side of the worm 12, a T-shaped rod 15 is fixedly connected to the left end of the worm wheel 13, a combustion furnace 3 is installed on the left side of the top of the bottom plate 1, the left end of the T-shaped rod 15 passes through the combustion furnace 3 and is fixedly connected to a fan plate 14, and a condensing mechanism 2 is installed on the right side of the bottom plate 1; an industrial fan 16 is installed on the left end of the top rear side of the bottom plate 1, the input end of the industrial fan 16 is connected to an air intake pipe 17, and the output end of the industrial fan 16 is connected to an exhaust pipe 7, and the front end of the exhaust pipe 7 is connected to the rear side of the combustion furnace 3;

[0031] Specifically, when the industrial fan 16 is turned on, the fan drives the air inlet pipe 17 to extract the exhaust gas and transports it to the combustion furnace 3 through a series of pipes; in this process, the flow speed and pressure of the exhaust gas are precisely controlled to ensure that the exhaust gas can smoothly enter the combustion furnace 3 and be effectively treated; after the exhaust gas enters the combustion furnace 3, how to achieve its full combustion becomes the core link of the treatment process; at this time, the role of the drive motor 10 is particularly important; by driving the active pulley 11 to rotate, the drive motor 10 provides a continuous source of power; the rotation of the active pulley 11 forms a linkage relationship with the driven pulley 8 through the connecting belt 9, thereby realizing the effective transfer of energy; the rotation of the driven pulley 8 drives the rotation of the fan blades 18; this air blowing downward not only helps to increase the residence time of the exhaust gas in the combustion furnace 3, but also promotes the filling of the exhaust gas and air. The exhaust gas is mixed with the worm 12 to improve the combustion efficiency; in addition, the rotation of the driving pulley 11 also causes the worm 12 to rotate synchronously; the meshing transmission relationship between the worm 12 and the worm wheel 13 enables the worm wheel 13 to rotate with the rotation of the worm 12; the rotation of the worm wheel 13 further drives the rotation of the fan plate 14; the fan plate 14 is a key component for fanning the exhaust gas, and its design must fully consider the relationship between the fanning effect and the resistance; through reasonable structural design and material selection, the fan plate 14 can effectively fan the exhaust gas, thereby increasing the diffusion range and residence time of the exhaust gas in the combustion furnace 3; through the combined effect of the fanning of the exhaust gas and the air blowing downward, the combustion time of the exhaust gas in the combustion furnace 3 is significantly increased; this can not only ensure that the exhaust gas is burned more fully, but also effectively avoid incomplete combustion decomposition due to the fast flow rate of the exhaust gas.

[0032] Reference Figure 1 and Figure 3 The condensing mechanism 2 includes an industrial fan 201, which is installed at the left end of the front side of the bottom plate 1. A condenser 202 is installed at the top right end of the bottom plate 1. A gear 204 is fixedly connected to the right side of the worm gear 13. A sawtooth bar 205 is meshed and connected to the bottom of the gear 204. A push rod 203 is fixedly connected to the right side of the sawtooth bar 205. A storage box 206 is arranged on the inner side of the condenser 202. A slide rail 21 is fixedly connected to the right side of the fixed frame 4, and the sawtooth bar 205 is slidably connected to the slide rail 21.

[0033] Specifically, the industrial fan 201 plays a vital role; it can not only extract the VOCs waste gas generated in the combustion furnace 3, but also ensure the stability and continuity of the waste gas during the transmission process; these waste gases are then discharged into the condenser 202; through the rotation of the worm gear 13, the gear 204 can be rotated; the rotation of the gear 204 is meshed with the sawtooth bar 205, thereby driving the sawtooth bar 205 to slide in the slide rail 21; this design not only plans the movement trajectory of the sawtooth bar 205, but also ensures the accuracy and stability of its movement; The movement of the serrated bar 205 also causes the push rod 203 to move synchronously; the purpose of this action is to push the storage box 206 into the condenser 202 so as to better receive the fallen solidified material; when the solidified material in the storage box 206 reaches a certain amount, the fully stored storage box 206 can be pushed out of the condenser 202 through the coordinated action of the push rod 203 and the serrated bar 205; this design enables the entire processing process to achieve the effect of synchronously connecting the storage condensate, without stopping work to manually replace the storage box 206, thereby greatly improving the processing efficiency and operating convenience.

[0034] Reference Figure 1 and Figure 3 , sealing strips 19 are installed on the front and rear sides of the top of the storage box 206; sliding strips 20 are fixedly connected to the left and right sides of the bottom of the storage box 206, and sliding grooves 6 are opened on the left and right sides of the inner bottom wall of the condenser 202, and the sliding strips 20 are slidably connected to the corresponding sliding grooves 6 respectively; the outer side of the condenser 202 is opened with a heat dissipation hole 5; the push rod 203 and the storage box 206 are symmetrically designed;

[0035] Specifically, the sealing strip 19 is used to prevent leakage of condensed air, the slide bar 20 slides in the slide groove 6, the moving trajectory of the storage box 206 is planned, the condenser 202 is cooled through the heat dissipation holes 5, and the accuracy of pushing the storage box 206 is increased through the symmetrical design of the push rod 203 and the storage box 206.

[0036] Working principle: When the VOCs waste gas of the cyclohexanol ketone device is recovered and processed, the air inlet pipe 17 is connected to the waste gas storage device, and the industrial fan 16 is turned on to drive the air inlet pipe 17 to extract the waste gas, and at the same time, the waste gas is discharged into the combustion furnace 3 through the exhaust pipe 7, and the driving motor 10 is turned on to drive the driving pulley 11 to rotate. The rotation of the driving pulley 11 is synchronously rotated by the connecting belt 9 and the driven pulley 8, and the rotation of the driven pulley 8 is accompanied by the rotation of the fan blade 18, so that the air is blown downward, and at the same time, the rotation of the driving pulley 11 is accompanied by the synchronous rotation of the worm 12, and the rotation of the worm 12 is meshed with the worm wheel 13 to drive the worm wheel 13 to rotate, and the rotation of the worm wheel 13 is accompanied by the rotation of the fan plate 14, so as to fan the waste gas. By fanning the waste gas and blowing the air downward, the combustion time of the waste gas in the combustion furnace 3 is increased, thereby avoiding the high flow rate of the waste gas. The situation of incomplete combustion and decomposition is avoided, thereby avoiding the influence of subsequent processes, and meeting the use requirements. The VOCs waste gas after combustion and decomposition in the combustion furnace 3 is extracted by the industrial fan 201 and discharged into the condenser 202. The waste gas is condensed by the condenser 202, so that the condensate falls into the storage box 206 for storage. At the same time, the rotation of the worm gear 13 causes the gear 204 to rotate, and the rotation of the gear 204 is meshed with the sawtooth bar 205 for transmission, thereby driving the sawtooth bar 205 to slide in the slide rail 21, and the movement trajectory of the sawtooth bar 205 is planned. The movement of the sawtooth bar 205 causes the push rod 203 to move synchronously, thereby pushing the storage box 206 into the condenser 202, and pushing the full storage box 206 out of the condenser 202, achieving the effect of synchronous connection and storage of condensate, without stopping work to manually replace the storage box 206, which is more time-saving and labor-saving.
