Description

Technical Field

[0001] This utility model relates to the technical field of filtration mechanisms for treating polyester waste gas, specifically a filtration mechanism for treating polyester waste gas. Background Technology

[0002] Polyester resin is the foundation of coatings, serving to bind other components in the coating to form a film. It plays a decisive role in the properties of the coating and the film, and its production volume is increasing. However, the production process of polyester resin generates a large amount of exhaust gas. If directly emitted into the atmosphere, it will cause significant environmental pollution and result in material waste.

[0003] Patent document CN220758481 U discloses a waste gas purification device for polyester resin synthesis, including a gas scrubbing tank and an adsorption drying tank. The gas scrubbing tank contains a filter screen with a bubble-breaking mechanism installed below it. An inlet pipe extends from the bottom of the gas scrubbing tank to the bottom of the tank and connects to an exhaust pipe at its end. The top of the gas scrubbing tank is connected to one side of the bottom of the adsorption drying tank via an air supply pipe equipped with an air pump. Inside the adsorption drying tank, guide plates are arranged alternately from bottom to top, with an activated carbon adsorption layer between the guide plates and the tank. A dryer is installed on the top of the adsorption drying tank. Gas flows sequentially into the interconnected gas scrubbing tank and adsorption drying tank according to its flow direction. This device employs a structure of multiple waste gas treatment mechanisms connected in series. For the multi-component waste gas generated during polyester resin synthesis, this series connection of multiple waste gas treatment mechanisms can efficiently achieve purification standards.

[0004] Although the device in the aforementioned application document adopts a structure of multiple waste gas treatment mechanisms connected in series, this method of multiple waste gas treatment mechanisms connected in series can efficiently meet the purification standards for multi-component waste gases generated during polyester resin synthesis. However, during use, the airflow will always seek the path of least resistance. After long-term operation, the activated carbon bed may form fixed channels due to sedimentation or airflow impact, causing most of the airflow to pass through without sufficient adsorption, thus reducing the overall efficiency.

[0005] Therefore, a filtration mechanism for treating polyester waste gas is proposed to solve the problems mentioned above. Utility Model Content

[0011] Preferably, the drive assembly includes a third rotating rod, a movable plate, a slide rod, and a motor.

[0015] Compared with the prior art, the present invention provides a filtration mechanism for treating polyester waste gas, which has the following beneficial effects:

[0016] First, the first striking mechanism, driven by a motor, causes the first striking block to strike the upper limiting plate. The vibration generated by this striking is transmitted to the activated carbon plate, making the activated carbon particles more compact, filling the gaps caused by minor vibrations during operation, preventing excessively low local resistance, and ensuring more sufficient contact between the exhaust gas and the activated carbon, thereby improving the adsorption efficiency of the activated carbon for pollutants in the exhaust gas.

[0017] II. The second striking mechanism achieves the striking of the lower limiting plate through the magnetic connection of the magnetic conductor and the permanent magnet, as well as the elastic action of the torsion spring. When the movable rod rotates counterclockwise, the magnetic conductor drives the permanent magnet to rotate, and the permanent magnet squeezes the second striking block, causing it to rotate clockwise and compress the torsion spring. When the movable rod rotates clockwise, the permanent magnet no longer squeezes the second striking block, and the elastic force of the torsion spring drives the second striking block to rotate counterclockwise, striking the lower limiting plate, further enhancing the vibration effect, making the vibration of the activated carbon plate more uniform and intense, further improving the density of the activated carbon particles, and ensuring full contact between the exhaust gas and the activated carbon.

Connected to the front of the inner wall of the protective shell 21, the movable rod 26 is fixedly sleeved on the outer wall of the arc-shaped surface of the first rotating rod 25, the movable groove 27 is opened on the front of the movable rod 26, the second rotating rod 29 is rotatably connected to the front of the inner wall of the adsorption drying chamber body 1 through the bearing, the first striking block 211 is fixedly sleeved on the outer wall of the arc-shaped surface of the second rotating rod 29, the adsorption drying chamber body 1 is equipped with a transmission assembly for driving the first rotating rod 25 and the second rotating rod 29, the back of the adsorption drying chamber body 1 is equipped with a drive assembly, and the adsorption drying chamber body 1 is equipped with a second striking mechanism.

[0030] The drive assembly includes a third rotating rod 212, a movable plate 213, a slide rod 214, and a motor 220. The third rotating rod 212 is rotatably connected to the front of the inner wall of the protective shell 21 via a bearing. The movable plate 213 is fixedly connected to the front of the third rotating rod 212. The slide rod 214 is fixedly connected to the front of the movable plate 213. The motor 220 is fixedly connected to the back of the protective shell 21. The third rotating rod 212 movably penetrates through the protective shell 21. The extended end of the third rotating rod 212 extends toward the back of the protective shell 21.

[0031] The adsorption drying chamber body 1 has a door 4 hinged to its front, an exhaust pipe 3 fixedly connected to its top, and an air inlet pipe 5 fixedly connected to its side.

[0032] In practical use, the above-mentioned equipment is activated by starting the motor 220, which drives the third rotating rod 212 to rotate.

[0036] In practical use, when the movable rod 26 rotates counterclockwise, it drives the magnetic conductor 215 to move. The magnetic conductor 215 drives the permanent magnet 216 to rotate. When the permanent magnet 216 rotates to its limit position, it presses the second striking block 218, causing the second striking block 218 to rotate clockwise around the hinge rod 219. At the same time, the torsion spring 221 is compressed. When the movable rod 26 rotates clockwise, the magnetic conductor 215 drives the permanent magnet 216 to rotate. When the permanent magnet 216 no longer presses the second striking block 218, the torsion spring 221 drives the hinge rod 219 to rotate counterclockwise.
