Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a printing waste gas treatment device. Background Technology

[0002] During the tape production process, some steps require printing patterns and text. The printing press generates a large amount of waste gas during this process. This waste gas mainly contains VOCs (volatile organic compounds) and other harmful gases, such as benzene, formaldehyde, and ammonia. These substances are highly volatile at room temperature and easily diffuse into the air, polluting the atmospheric environment.

[0003] In existing printing waste gas treatment, activated carbon plates are typically used to adsorb organic and inorganic substances in the waste gas. However, dust in the waste gas can clog the activated carbon plates, reducing their adsorption capacity and thus reducing the waste gas treatment effect. Utility Model Content

[0004] The purpose of this invention is to provide a printing waste gas treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a printing waste gas treatment device, comprising a treatment box, an air inlet pipe fixedly connected to the upper left side of the treatment box, an isolation frame fixedly connected to the left side of the treatment box, a filter cover fixedly connected between the isolation frame and the inner wall of the treatment box, two sets of guide plates fixedly connected to the inner wall of the treatment box, an isolation plate fixedly connected to the right side inside the treatment box, an installation rail fixedly connected to the isolation frame, guide plates, and isolation plate facing each other on one side, an activated carbon plate slidably connected inside the installation rail, an air guide pipe fixedly connected to the upper part of the isolation plate, and an air outlet pipe and a water inlet pipe fixedly connected to the upper and lower right sides of the treatment box.

[0006] Preferably, a rotating tube is rotatably connected inside the right side of the processing box, and several sets of air blowing tubes are fixedly connected to the outside of the rotating tube. A pulse box is fixedly connected to the upper part of the processing box, and a connecting tube is fixedly connected to one side of the pulse box. The other end of the connecting tube is sleeved inside the rotating tube.

[0007] Preferably, an external gear is fixedly connected to the upper part of the rotating tube through the outside of the processing box, a mounting frame is fixedly connected to the upper part of the processing box, a motor is fixedly connected to the upper part of the mounting frame, a connecting gear is fixedly connected to the power end of the motor, and the connecting gear meshes with the external gear.

[0008] Preferably, two sets of mounting plates are fixedly connected to the upper part of the activated carbon plate, and a handle is fixedly connected to the front side of the activated carbon plate.

[0009] Preferably, a maintenance door is connected to the left side of the processing box via a rotating shaft, and the maintenance door faces the filter cover.

[0010] Preferably, a glass plate is fixedly connected to the inside of the right side of the processing box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model allows air to enter through the inlet pipe, pass through the filter cover, and then enter the outer side of the isolation frame from the bottom of the filter cover. The air is then guided by the guide plate to pass through the multi-layer activated carbon plate for air treatment. The treated air enters the water on one side of the isolation plate through the air guide pipe and is then discharged from the outlet pipe. This method can clean dust, inorganic matter, organic matter, and malodorous odors in exhaust gas, thereby improving the air cleaning effect.

[0013] 2. This utility model also uses a motor to drive a connecting gear, which in turn drives the rotating tube to rotate. The pulse box generates a pulse airflow, which enters the rotating tube through the connecting tube. The blowing pipe blows the air onto the outer wall of the filter cover, causing impurities on the outside of the filter cover to fall off. Opening the maintenance door allows for the recovery of dust, preventing dust accumulation from clogging the air handling equipment. Attached Figure Description

[0019] Please see Figure 1-3 This utility model provides a technical solution: a printing waste gas treatment device, including a treatment box 1. An air inlet pipe 2 is fixedly welded to the upper left side of the treatment box 1. An isolation frame 3 is fixedly welded to the left side of the treatment box 1. A filter cover 4 is fixedly welded between the isolation frame 3 and the inner wall of the treatment box 1. The filter cover 4 can filter dust in the waste gas. Two sets of guide plates 5 are fixedly welded to the inner wall of the treatment box 1. The guide plates 5 control the air flow direction. An isolation plate 8 is fixedly welded to the right side of the inside of the treatment box 1. An installation rail 6 is fixedly welded to one side facing the isolation frame 3, the guide plate 5, and the isolation plate 8. An activated carbon plate 7 is slidably installed inside the installation rail 6. The air passes through the multi-layer activated carbon plate 7 to treat the waste gas. A duct pipe 9 is fixedly welded to the upper part of the isolation plate 8. An outlet pipe 10 and a water inlet pipe 11 are fixedly welded to the upper and lower right sides of the treatment box 1. By controlling the switch of the water inlet pipe 11, water is added to one side of the isolation plate 8 inside the treatment box 1. The water submerges the lower part of the duct pipe 9, so that the waste gas passes through the water and is discharged from the outlet pipe 10, further improving the waste gas treatment effect.

[0020] A rotating tube 12 is rotatably mounted inside the right side of the treatment box 1. Several sets of air blowing pipes 13 are fixedly welded to the outside of the rotating tube 12. A pulse box 16 is fixedly welded to the upper part of the treatment box 1. A connecting pipe 15 is fixedly welded to one side of the pulse box 16. The other end of the connecting pipe 15 is sleeved inside the rotating tube 12. The pulse box 16 generates pulsed airflow, which enters the rotating tube 12 through the connecting pipe 15. The air blowing pipes 13 blow towards the outer wall of the filter cover 4, causing impurities on the outside of the filter cover 4 to be blown off. An external gear 14 is fixedly welded to the upper part of the rotating tube 12, penetrating the outside of the treatment box 1. A mounting bracket 17 is fixedly welded to the upper part of the treatment box 1. A motor 18 is mounted on the flange of the mounting bracket 17. The power end of the motor 18 is connected to a coupling. A connecting gear 19 meshes with an external gear 14. The motor 18 drives the connecting gear 19, which in turn drives the rotating tube 12 to rotate via the external gear 14, allowing the air blowing tube 13 to blow air to various positions on the filter cover 4. Two sets of mounting plates 20 are fixedly welded to the upper part of the activated carbon plate 7. The mounting plates 20 are connected to the outside of the treatment box 1 by screws to realize the installation of the activated carbon plate 7. A handle 21 is fixedly welded to the front side of the activated carbon plate 7 for easy removal. A maintenance door 22 is connected to the left side of the treatment box 1 via a rotating shaft. The maintenance door 22 faces the filter cover 4, making it easy to open the treatment box 1 and recover impurities. A glass plate 23 is adhered to the inside of the right side of the treatment box 1, allowing the water level to be observed from the outside.

[0021] Working principle: When in use, air enters through the inlet pipe 2, passes through the filter cover 4, and then enters the outer side of the isolation frame 3 from the lower part of the filter cover 4. The air flow is then guided by the guide plate 5, allowing the air to pass through the multi-layer activated carbon plate 7 for air treatment. The treated air enters the water on one side of the isolation plate 8 through the air guide pipe 9, and then is discharged from the air outlet pipe 10, improving the air cleaning effect. The motor 18 drives the connecting gear 19, which drives the rotating tube 12 to rotate through the external gear 14. The pulse box 16 generates pulse airflow, which enters the rotating tube 12 through the connecting pipe 15. The blowing pipe 13 blows towards the outer wall of the filter cover 4, causing impurities on the outside of the filter cover 4 to fall off. By opening the maintenance door 22, dust can be recovered.
