Description

Azobisisobutyronitrile (AISO) production tail gas recovery and treatment device Technical Field

[0001] This utility model relates to the field of exhaust gas recovery and treatment devices, and in particular to exhaust gas recovery and treatment devices for the production of azobisisobutyronitrile. Background Technology

[0002] The exhaust gas recovery and treatment device is an environmental protection equipment used to purify the gas produced by azobisisobutyronitrile (AIBN). Its main function is to recover harmful substances in the waste gas and convert them into harmless substances or reusable resources, thereby reducing air pollution, ensuring that emissions meet standards, and reducing resource waste and environmental harm.

[0003] Existing exhaust gas recovery and treatment devices lack the function of transporting goods. Without this function, workers may have to carry too many tools to climb to the top for maintenance or installation, which could lead to excessive physical exhaustion and increase the safety risks for workers climbing to the top.

[0004] Therefore, in view of the lack of a function for transporting goods in the existing exhaust gas recovery and treatment devices, the problem that workers have to carry tools to the top, which leads to excessive physical exertion and increased safety risks, there is an urgent need to design a new type of exhaust gas recovery and treatment device for azobisisobutyronitrile (AIBN) production. Summary of the Invention

[0005] In order to overcome the problem that the existing exhaust gas recovery and treatment device lacks the function of transporting goods, the staff have to carry tools to the top, which leads to excessive physical exhaustion and increases the safety risks of climbing to the top.

[0006] The technical solution of this utility model is as follows: a tail gas recovery and treatment device for the production of azobisisobutyronitrile (AIBN), including a chamber body; it also includes a ladder, an installation platform, a lifting frame, a motor, a lead screw, a slider, and a storage compartment. A ladder is provided on the rear side of the outer surface of the chamber body, an installation platform is installed on the right surface of the ladder, a lifting frame is provided on the rear surface of the installation platform, a motor is installed on the upper surface of the lifting frame, the output end of the motor passes through the upper surface of the lifting frame and is connected to a lead screw, the lower surface of the lead screw is rotatably connected to the lower inner surface of the lifting frame, a slider is threadedly connected to the outer surface of the lead screw, and a storage compartment is installed on the rear surface of the slider.

[0007] Preferably, by setting up a motor, the motor drives the lead screw to rotate when running. When the lead screw rotates, the rotation of the slider is restricted by the lifting frame, thereby driving the slider to move. When the slider moves, it drives the storage compartment to move. When the staff needs to use the ladder to climb to the top of the compartment for installation or maintenance, the workpiece can be placed inside the storage compartment. The motor is started by the external controller to send the storage compartment to the top, making it easier and more convenient for the staff to climb the ladder. This reduces the burden on the staff when climbing the ladder and solves the problem that the existing exhaust gas recovery and treatment device lacks the function of transporting items. Without the function of transporting items, the staff may have to carry too many tools to climb to the top for maintenance or installation, which will lead to excessive physical exhaustion and increase the safety risks of the staff climbing to the top.

[0008] Preferably, the outer surface of the container is provided with symmetrical observation tubes, and the front surface of each observation tube is equipped with a mounting frame, with glass installed inside the mounting frame.

[0009] Preferably, a clamping chamber is provided on the lower left side of the outer surface of the chamber body. A water pump is installed on the lower rear surface of the clamping chamber. One end of a pipe is connected to the rear surface of the water pump, and the other end of the pipe is connected to a pipe. Both outlets of the pipe are connected to spray pipes through the left side of the outer surface of the chamber body. A return trough is provided on the lower left side of the outer surface of the chamber body.

[0010] Preferably, the interior of the chamber is equipped with mounting brackets on the lower side of the two spray pipes, and the upper surface of the two mounting brackets is equipped with perforated plates.

[0011] Preferably, the upper surface of the compartment is connected to a baffle via a hinge, and the upper surface of the baffle is fitted with symmetrical handles.

[0012] Preferably, a second water pump is provided on the lower left surface of the compartment, and a third pipe is connected to the left surface of the second water pump.

[0013] Preferably, an air inlet is connected to the lower front side of the outer surface of the chamber, and an air outlet is connected to the upper surface of the chamber.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a motor, the motor drives the lead screw to perform rotational action when it is running. During the rotation of the lead screw, the radial degree of freedom of the slider is locked by the lifting frame, and the rotational kinetic energy of the lead screw is converted into the vertical linear displacement of the slider. When the slider moves up and down along the lead screw, the storage bin is synchronously pulled vertically through the rigid connection. When the operator needs to climb to the top of the bin to perform installation or maintenance work, the tools or workpieces can be placed in the storage bin in advance. The motor drive module is activated by the command system of the external controller, so that the storage bin is lifted to the target height along the vertical trajectory. This reduces the burden of climbing the ladder for the operator and solves the problem that the existing exhaust gas recovery and treatment device lacks the function of transporting items. Without the function of transporting items, the operator may have to carry too many tools to the top for maintenance or installation, which will lead to the operator's physical exhaustion and increase the safety risk of the operator climbing to the top.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to Figures 1-4. This utility model provides an embodiment of a tail gas recovery and treatment device for azobisisobutyronitrile (AIB) production, including a chamber 1; it also includes a ladder 2, an installation platform 3, a lifting frame 4, a motor 5, a lead screw 6, a slider 7, and a storage chamber 8. The ladder 2 is provided on the rear side of the outer surface of the chamber 1. The installation platform 3 is installed on the right surface of the ladder 2. The lifting frame 4 is provided on the rear surface of the installation platform 3. The motor 5 is installed on the upper surface of the lifting frame 4. The output end of the motor 5 passes through the upper surface of the lifting frame 4 and is connected to the lead screw 6. The lower surface of the lead screw 6 is rotatably connected to the lower inner surface of the lifting frame 4. The outer surface of the lead screw 6... A slider 7 is threadedly connected, and a storage compartment 8 is installed on the rear surface of the slider 7. A motor 5 is installed, which drives the lead screw 6 to rotate when it runs. When the lead screw 6 rotates, the rotation of the slider 7 is restricted by the lifting frame 4, thereby driving the slider 7 to move. When the slider 7 moves, it drives the storage compartment 8 to move. When the staff needs to use the ladder 2 to climb to the top of the compartment 1 for installation or maintenance, the workpiece can be placed inside the storage compartment 8. The motor 5 is started by the external controller to send the storage compartment 8 to the top, so that the staff can climb the ladder 2 more easily and conveniently, thereby reducing the burden on the staff when climbing the ladder 2.

[0023] Please refer to Figures 1-3. In this embodiment, symmetrical observation tubes 9 are provided on the upper front side of the outer surface of the chamber 1. A mounting frame 10 is installed on the front surface of each observation tube 9, and a glass 11 is installed inside the mounting frame 10. Through the glass 11, staff can clearly see the internal condition of the chamber 1, avoiding situations where there are internal abnormalities but the outside is unaware, thus assisting staff in their work. A clamping chamber 12 is located on the lower left side of the outer surface of the chamber 1. A water pump 13 is installed on the lower rear surface of the clamping chamber 12. One end of a pipe 14 is connected to the rear surface of the water pump 13, and the other end of the pipe 14 is connected to a pipe 2 15. Both outlets of the pipe 2 15 penetrate the left side of the outer surface of the chamber 1 and are connected to spray pipes 16. A return channel 23 is provided on the lower left side of the outer surface of the chamber 1. A clamping chamber 12 is provided to store the spray liquid. A water pump 13 is provided to pump the spray liquid inside the clamping chamber 12 into the two spray pipes 16 through pipes 14 and 15. Finally, as the atomizing nozzles of the spray pipes 16 spray outward, the spray liquid falls to the bottom of the chamber 1 and returns to the clamping chamber 12 through the return channel 23 for circulation. This achieves the purpose of absorbing pollutants through gas-liquid contact. Inside the chamber 1, under the two spray pipes 16, there are mounting brackets 17. The upper surface of the two mounting brackets 17 is equipped with perforated plates 18. By setting the perforated plates 18, the gas can pass through the perforated plates 18 and continue to rise. By placing filter filler on the perforated plates 18, the gas can adsorb harmful substances in the gas when it passes through the perforated plates 18, thereby enhancing the filtration effect.

[0024] Please refer to Figures 1-4. In this embodiment, a baffle 19 is hinged to the upper surface of the clamping chamber 12. A symmetrical handle 20 is installed on the upper surface of the baffle 19. By setting the baffle 19, it can be opened to add spray liquid when needed. The handles 20 provide a point of leverage for the operator to open the baffle 19, making it easier to open. A second water pump 21 is installed on the lower left side of the clamping chamber 12. A third pipe 22 is connected to the left surface of the second water pump 21. By setting up water pump 21, when the spray liquid inside the clamping chamber 12 can no longer be recycled, water pump 21 is started to discharge the spray liquid inside the clamping chamber 12 through pipe 3 22, thereby achieving the purpose of discharging waste gas spray liquid. An air inlet 24 is connected to the lower front side of the outer surface of the chamber body 1, and an air outlet 25 is connected to the upper surface of the chamber body 1. By setting up air inlet 24, waste gas can enter the interior of the chamber body 1 for filtration, and then the filtered gas can be discharged through air outlet 25. The flow of gas relies on an externally connected exhaust fan.

[0025] During operation, the installation of glass 11 allows workers to clearly see the interior of the chamber 1, preventing situations where abnormalities occur internally without the outside world's knowledge. This assists workers in their work. A clamping chamber 12 stores the spraying liquid. A water pump 13 pumps the spraying liquid from the clamping chamber 12 through pipes 14 and 15 into two spray pipes 16. The sprayed liquid, sprayed outwards from the atomizing nozzles of the spray pipes 16, falls to the bottom of the chamber 1 and returns to the clamping chamber 12 via the return channel 23 for circulation. This achieves the absorption of pollutants through gas-liquid contact. A perforated plate 18 allows gas to pass through and rise. Furthermore, a... The filter filler is placed so that when the gas passes through the perforated plate 18, it can adsorb harmful substances in the gas, thereby enhancing the filtration effect. By setting baffle 19, the baffle 19 can be opened to add spray liquid when needed. By setting handle 20, the operator can have a point of force to open the baffle 19, making it easier to open. By setting water pump 21, when the spray liquid inside the compartment 12 can no longer be recycled, water pump 21 is activated to discharge the spray liquid inside the compartment 12 through pipe 3 22, thereby achieving the purpose of discharging waste gas spray liquid. By setting air inlet 24, waste gas can enter the compartment 1 for filtration, and by setting air outlet 25, the filtered gas can be discharged. The flow of gas relies on an externally connected exhaust fan.

[0026] Through the above steps, by setting up motor 5, when motor 5 is running, it drives lead screw 6 to perform rotational action. During the rotation of lead screw 6, relying on the radial degree of freedom locking mechanism of slider 7 by lifting frame 4, the rotational kinetic energy of lead screw 6 is converted into vertical linear displacement of slider 7. When slider 7 moves up and down along lead screw 6, it synchronously pulls storage bin 8 to perform vertical displacement through rigid connection. When operators need to climb to the top of bin 1 to perform installation or maintenance work using ladder 2, tools or workpieces can be placed in storage bin 8 in advance. The motor 5 drive module is activated by the command system of external controller, so that storage bin 8 is lifted to the target height along the vertical trajectory. This reduces the burden on workers climbing ladder 2 and solves the problem that the existing exhaust gas recovery and treatment device lacks the function of transporting items. Because it lacks the function of transporting items, workers may have to carry too many tools to the top for maintenance or installation, which will lead to excessive physical exhaustion and increase the safety risks of workers climbing to the top.
