Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4The injection molding waste gas treatment device includes a base 1, on the upper surface of which a treatment box 2 and an air supply fan 3 are fixedly installed. Four fixed cones 15 are arranged inside the base 1, and the bottom end of each fixed cone 15 passes through the bottom of the base 1. The fixed cones 15 are used to fix the base 1 on the ground, thereby preventing the base 1 from moving on its own, thereby ensuring the stability of the base 1.

[0024] The output end of the air supply fan 3 is fixedly connected to the air intake pipe 4, the right end of the air intake pipe 4 passes through the interior of the processing box 2, the inner wall of the processing box 2 is fixedly installed with a heat storage box 16, and the outer surface of the air supply pipe 4 is fixedly connected to a fire arrester 17. The heat storage box 16 is made of heat storage bricks, so that it can store heat to a certain extent, thereby playing a role in reducing energy consumption. The installation of the fire arrester 17 can prevent the flame from contacting the air supply fan 3 through the air intake pipe 4, thereby playing a certain protective role for the air supply fan 3.

[0025] A burner 5 is fixedly installed on the left side of the processing box 2, and a natural gas pipe 6 is fixedly connected to the left side of the burner 5. A combustion-supporting fan 7 is fixedly installed on the upper surface of the burner 5, and the air outlet end of the combustion-supporting fan 7 passes through the interior of the burner 5. The outer surface of the air inlet end of the air supply fan 3 and the outer surface of the natural gas pipe 6 are fixedly installed with a connecting flange 21. The interior of each connecting flange 21 is threaded with two groups of fixing bolts 22, and the left end of each fixing bolt 22 passes through the left side of the connecting flange 21. The connecting flange 21 and the fixing bolts 22 are used to fix the exhaust gas delivery pipeline and the air supply fan 3, and the natural gas pipe 6 is fixedly connected to the natural gas delivery pipeline, so as to facilitate workers to install and disassemble.

[0026] The right side of the burner 5 is fixedly connected to a connecting pipe 8, the right end of the connecting pipe 8 passes through the interior of the processing box 2, and the left side of the processing box 2 is fixedly installed with a temperature sensor 18, an air pressure sensor 19 and a controller 20. The detection ends of the temperature sensor 18 and the air pressure sensor 19 pass through the interior of the processing box 2. The controller 20 is electrically connected to the temperature sensor 18 and the air pressure sensor 19 through wires. The model of the temperature sensor 18 is PT100, and the model of the air pressure sensor 19 is MS5611. The temperature sensor 18 and the air pressure sensor 19 are used to perform real-time detection of the temperature and air pressure inside the processing box 2, so that workers can understand the temperature and gas inside the processing box 2.

[0027] A dustproof frame 9 is clamped inside the processing box 2, and the internal threads of the dustproof frame 9 are connected to two sets of connecting bolts 23. The bottom end of each connecting bolt 23 passes through the interior of the processing box 2. The dustproof frame 9 is fixed to the interior of the processing box 2 by the connecting bolts 23, thereby preventing the dustproof frame 9 from moving on its own, thereby ensuring the stability of the dustproof frame 9.

[0028] A rotating motor 10 is provided above the processing box 2. The output end of the rotating motor 10 passes through the processing box 2 and is fixedly installed with a turntable 11. Two fixing frames 24 are fixedly installed on the outer surface of the rotating motor 10. The bottom surface of each fixing frame 24 is fixedly connected to the upper surface of the processing box 2. The installation of the fixing frame 24 fixes the rotating motor 10, thereby preventing the rotating motor 10 from rotating during operation, thereby ensuring the stability of the operation of the rotating motor 10.

[0029] A connecting column 12 is fixedly installed on the bottom surface of the turntable 11, and a movable frame 13 is provided below the turntable 11. The inner wall of the movable frame 13 is slidably connected to the outer surface of the connecting column 12. A rubber hammer 14 is fixedly installed on the right end of the movable frame 13. A limiting seat 25 is fixedly installed on the inner top wall of the heat storage box 16. The inner wall of the limiting seat 25 is slidably connected to the outer surface of the movable frame 13. The installation of the limiting seat 25 plays a role in limiting the moving trajectory of the movable frame 13, thereby preventing the movable frame 13 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the movable frame 13.

[0030] The working principle of the utility model is as follows: when in use, the worker fixes the exhaust gas delivery pipeline and the natural gas delivery pipeline to the air supply fan 3 and the natural gas pipe 6 respectively through the connecting flange 21 and the fixing bolt 22, and then turns on the air supply fan 3, the burner 5, the combustion-supporting fan 7 and the rotating motor 10, and uses the power provided by the air supply fan 3 to transport the exhaust gas through the air intake pipe 4 to the inside of the treatment box 2. At the same time, the natural gas transported through the natural gas pipe 6 cooperates with the combustion-supporting fan 7 to enable the burner 5 to heat the exhaust gas inside the treatment box 2, so that the temperature inside the treatment box 2 is at 800°C. Around, thereby making the VOCs waste gas decompose into carbon dioxide and water vapor under the action of high temperature, and then discharge into the treatment box 2 after passing through the dustproof frame 9, and at the same time, the power provided by the rotating motor 10 is used to drive the turntable 11 to rotate, so that the turntable 11 drives the connecting column 12 to rotate, so that the connecting column 12 drives the movable frame 13 to move back and forth under the restriction of the limit seat 25, so that the movable frame 13 drives the rubber hammer 14 to knock on the dustproof frame 9, so as to prevent dust from clogging the dustproof frame 9, thereby eliminating the need for workers to frequently stop the machine to replace the activated carbon plate, thereby increasing the waste gas treatment efficiency.
