Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a waste gas treatment device for a stretch film production equipment. Background Technology

[0002] The production of stretch film uses polyethylene and other resins as raw materials, and is manufactured through processes such as extrusion and casting. These processes generate waste gas containing oil mist and volatile organic compounds. To prevent these waste gases from causing air pollution, an electrostatic precipitator can be used for treatment. This equipment uses the principle of high-voltage electrostatics to charge oil mist particles, and then uses an electric field to adsorb the charged particles, efficiently removing oil mist from the waste gas. The electrostatic precipitator, used as a pretreatment step in conjunction with other equipment, constitutes an effective treatment system for various air pollutants in production waste gas, ultimately ensuring the safe emission of waste gas generated during stretch film production.

[0003] In existing technologies, a uniform air distribution plate is installed inside the air inlet chamber of an electrostatic precipitator to transform uneven and turbulent exhaust gas into a uniform and stable flow field, thereby ensuring the efficient and stable operation of the electrostatic precipitator. Because the uniform air distribution plate is located at the very front of the electrostatic precipitator and directly faces the untreated exhaust gas, it is most susceptible to contamination. Solid particles carried in the exhaust gas (such as lint, fibers, or packaging material debris in the workshop air) and sticky oil mist (formed by polymer degradation or additive volatilization during stretch film production) adhere to the surface of the uniform air distribution plate, combining to form a muddy oily residue. This gradually clogs the ventilation holes in the plate, eventually reducing the effective area of ​​the ventilation holes until they are completely blocked, resulting in reduced efficiency in treating exhaust gas. Therefore, the uniform air distribution plate needs to be cleaned regularly. However, existing uniform air distribution plates are usually large, single-piece installations, resulting in a large overall volume and weight. Disassembly requires multiple people, making the operation cumbersome and laborious. Summary of the Invention

The pressure block 34 cooperates with the limit frame 32. A spring 35 is fixedly installed between the bottom of the snap-fit ​​block 33 and the inner wall of the L-shaped rod 36.

[0038] Working principle: When in use, the exhaust gas is introduced into the air inlet chamber 1. Under the action of multiple air distribution plates 7, the exhaust gas flows upward evenly and enters the flue gas purification device 3. The flue gas purification device 3 treats the exhaust gas, and the treated gas is discharged through the air outlet chamber 2. When used in conjunction with other equipment, it can prevent these exhaust gases from causing air pollution problems.

[0039] After prolonged use, multiple air distribution plates 7 need to be cleaned. Remove one of the air distribution plates 7. First, rotate the threaded rod 23. Under the action of the two limiting rods 25, the two transmission blocks 24 move synchronously. The transmission shafts 28 on both sides of the two transmission blocks 24 first slide along their respective stroke grooves 21, simultaneously driving the corresponding transmission frames 19 to slide along their respective guide rods 18. Under the action of multiple connecting mechanisms, the multiple L-shaped rods 36 are connected to their respective irregular brackets 29. Therefore, during the movement of the two transmission blocks 24, the two crossbars 9 move synchronously along their respective mounting blocks 10, and drive multiple transmission shafts 11 to move synchronously. The multiple transmission shafts 11... Each corresponding slide 15 slides inside, and multiple rotating shafts 12 rotate under force, driving their corresponding limiting blocks 13 to move synchronously. The multiple limiting blocks 13 move away from the top of the air distribution plate 7 and no longer limit the top of the air distribution plate 7, so the workers can take out the air distribution plate 7. In this invention, the multiple small-sized air distribution plates 7 are set. Compared with the large-sized whole air distribution plates 7 in the prior art, each air distribution plate 7 is lighter and can be disassembled by a single person without the need for multiple people to cooperate. Moreover, the limiting mechanism used to fix the air distribution plate 7 is simple to operate, saving time and effort. By disassembling and cleaning multiple air distribution plates 7 and using them in conjunction with other equipment, it is possible to prevent the exhaust gas generated by the production of stretch film from causing air pollution.

[0040] During the movement of the two transmission blocks 24, the L-shaped rods 36 at their bottom move synchronously. When the multiple transmission shafts 28 move to a position close to their respective stroke grooves 21, multiple connecting mechanisms move accordingly. The movement process of one of the connecting mechanisms is as follows: the L-shaped rod 36 drives the locking block 33, the pressure block 34, and the spring 35 to move synchronously. When the corresponding transmission shaft 28 moves to a position close to its corresponding stroke groove 21, the pressure block 34 touches the limit bracket 32. The pressure block 34 is then forced to move the spring 35 downward, and the locking block 33 moves downward synchronously. The locking block 33 then disengages from the locking groove 31, and the L-shaped rod 36 is disconnected from the irregular bracket 29. The other multiple connecting mechanisms follow the same action process as described above. Subsequently, as the two transmission blocks 28 move, the L-shaped rod 36 moves to a position close to its corresponding stroke groove 21, and the L-shaped rod 36 moves to a position close to its corresponding stroke groove 21. As the moving block 24 moves, the two crossbars 9 no longer move synchronously. The transmission shafts 28 on both sides of the two transmission blocks 24 begin to gradually slide into their respective stroke grooves 22. The multiple transmission shafts 28 move upward along their respective guide rods 27, thereby driving their respective transmission frames 19 to move upward. The two lifting brackets 16 move upward steadily along their respective guide rods 17. The two lifting brackets 16 lift the top air distribution plate 7. When the air distribution plate 7 is stuck to the mounting frame 5 due to sticky oil stains and needs to be removed with effort, the lifting mechanism can lift the air distribution plate 7 upward a distance, making it convenient for the staff to quickly remove the air distribution plate 7 without having to lift it upward with force.

[0041] After removing the air distribution plate 7, rotate the threaded rod 23 in the opposite direction to move the multiple transmission shafts 28 into their respective stroke slots 21. Then, place the clean air distribution plate 7 into the mounting slot 6. Continue to rotate the threaded rod 23 in the opposite direction. The two transmission blocks 24 drive the multiple L-shaped rods 36 to move into their respective placement slots 30. Under the action of multiple snap-fit ​​components, the multiple L-shaped rods 36 are reconnected to their respective irregular brackets 29.
