Abstract
Description
Technical Field
[0001] This utility model belongs to the field of oil fume filtration technology, specifically relating to a multi-stage oil fume filtration and purification device. Background Technology
[0002] Multi-stage fume filtration purifiers are devices used in the textile printing and dyeing industry to treat the large amounts of oil fumes, waste gases, and harmful substances generated during the printing and dyeing process. Their main working principle typically includes multiple stages such as physical separation, electrostatic purification, chemical adsorption, or biodegradation. They not only effectively remove pollutants such as organic matter, pigments, and solvents from the oil fumes, improving air quality, but also reduce oil fume emissions, lowering atmospheric pollution and minimizing the health hazards to workers. Multi-stage fume filtration purifiers have wide applications in the textile printing and dyeing industry, including but not limited to: printing and dyeing workshops, textile post-processing workshops, and other related workshops.
[0003] Chinese Patent Publication No. CN221950811U relates to the field of air purifier filter technology, providing a multi-stage filtration air purifier filter, including an air purifier device and a protective net. The air purifier device includes a housing, an air inlet, fixed casters, an air outlet, a negative pressure fan, and a dustproof net. This utility model, by setting a limiting structure, moves a first fixed frame to one end of a limiting seat inside the housing, so that both ends of the first fixed frame are located between the limiting seats. Pushing the first fixed frame causes it to move a locking block into the interior of a movable groove. Under the elastic force of a return spring, a return plate moves the locking block into the locking groove, so that the locking block and the first fixed frame are locked together through the locking groove. Pulling the first fixed frame causes it to move the protective net to the outside of the housing, facilitating cleaning of the protective net. This enables the device to easily replace the protective net, thereby improving the convenience of using the multi-stage filtration air purifier filter.
[0004] In practical use, this utility model can filter and purify the oil fumes generated in the textile printing and dyeing process to a certain extent, removing impurities and harmful substances. However, existing multi-stage oil fume filtration purifiers rely on a single set of multiple filter components to achieve this effect. This relatively simple filtration method has limitations in practical applications, resulting in an unsatisfactory filtration effect. It is difficult to achieve deep removal of all impurities and harmful substances in textile printing and dyeing oil fumes, making existing multi-stage oil fume filtration purifiers insufficient in thoroughly removing oil fume pollutants, thus affecting the overall practical performance of the equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0032] Example 1:
[0033] Please see Figure 1-6 This utility model provides a multi-stage oil fume filter purifier, comprising:
[0034] Purification box 1 and mounting cover 2;
[0035] Fan 3 is located on one side of purification box 1. A filter screen 4 is provided on one side of fan 3, which can initially filter impurities and foreign objects in the air. A ventilation pipe 5 is provided at one end of fan 3, and the other end of ventilation pipe 5 is connected to the bottom of purification box 1.
[0036] Mounting plate 6 is set inside the purification box 1. A drive shaft 7 is rotatably connected to one side of the mounting plate 6. An installation groove is provided on the inner wall of the purification box 1 located on one side of the mounting plate 6, and a filter plate 8 is provided in the installation groove.
[0037] The filter frame 9 is located at the top of the purification box 1. The mounting cover 2 is equipped with an exhaust pipe 10, and the exhaust pipe 10 is equipped with a filter layer 11, which can perform final filtration on the purified textile printing and dyeing oil fume, thus improving the purification effect. A drain pipe 12 is provided on one side of the bottom of the purification box 1.
[0038] Specifically, such as Figure 1 and Figure 2As shown, both the purification chamber 1 and the mounting cover 2 are provided with mounting rings 13 on their outer sides. The two mounting rings 13 are connected by multiple fixing bolts 14. The mounting cover 2 can be easily installed or removed by the two mounting rings 13 and the multiple fixing bolts 14, so that the components inside the purification chamber 1 can be easily maintained.
[0039] Specifically, such as Figure 2 and Figure 4 As shown, multiple cleaning brushes 15 are provided on the outer side of the drive shaft 7, and the multiple cleaning brushes 15 all abut against the upper end of the filter plate 8.
[0040] Through its design, multiple cleaning brushes 15 can conveniently and effectively clean impurities and foreign objects clogging the filter plate 8 when the drive shaft 7 rotates, ensuring the filter plate 8's effect on filtering and purifying textile printing and dyeing oil fumes.
[0041] Specifically, such as Figure 2 and Figure 3 As shown, multiple fixing plates 16 are provided on the outside of the drive shaft 7. Each fixing plate 16 is rotatably connected to a positioning shaft 17. Multiple stirring rods 18 are provided on the outside of each positioning shaft 17. When the drive shaft 7 rotates, it will drive the multiple positioning shafts 17 and the multiple stirring rods 18 to rotate through the multiple fixing plates 16, so that the washing liquid can be fully mixed with the textile printing and dyeing oil fume.
[0042] Specifically, such as Figure 2 and Figure 3 As shown, the bottom of the purification box 1 located outside the drive shaft 7 is fixedly equipped with an installation wheel 19. The bottom of multiple positioning shafts 17 is equipped with positioning wheels 20 that are compatible with the installation. The multiple positioning wheels 20 are engaged with the installation wheel 19. The installation wheel 19 at the bottom of the purification box 1, together with the positioning wheels 20 at the bottom of multiple positioning shafts 17, allows the multiple positioning shafts 17 and multiple stirring rods 18 to rotate on their own during rotation, which further improves the mixing effect of washing liquid and textile printing and dyeing oil fume, and ensures that the washing liquid can deeply contact every fine particle in the oil fume.
[0043] Specifically, such as Figure 2 and Figure 3 As shown, the bottom of the purification box 1 is equipped with a drive motor 21. The drive motor 21 is existing technology and will not be described in detail here. The bottom of the drive shaft 7 passes through the purification box 1 and is set on the output end of the drive motor 21.
[0044] Specifically, such as Figure 2 , Figure 5 and Figure 6As shown, the filter frame 9 is equipped with an adsorption component 22, which can effectively remove impurities and harmful substances from textile printing and dyeing fumes. The upper end of the drive shaft 7 is equipped with a mounting plate 23. Both the upper end of the mounting plate 23 and the bottom end of the filter frame 9 are equipped with multiple contact blocks 24. The multiple contact blocks 24 are all hemispherical and staggered. When the drive shaft 7 drives the mounting plate 23 to rotate, the multiple contact blocks 24 can intermittently contact each other, thereby causing the filter frame 9 to vibrate up and down. This can further adjust the position of the adsorption component 22 and ensure its effectiveness in removing impurities and harmful substances from textile printing and dyeing fumes.
[0045] Specifically, such as Figure 2 and Figure 6 As shown, the bottom of the mounting cover 2 is provided with multiple mounting sleeves 25, and each mounting sleeve 25 is provided with a matching mounting rod 26. The bottom of each mounting rod 26 is located on the upper end of the filter frame 9. The multiple mounting sleeves 25 and the multiple mounting rods 26 can restrict the vertical movement of the filter frame 9 and prevent its position from shifting.
[0046] Specifically, such as Figure 2 and Figure 6 As shown, each of the multiple mounting rods 26 is provided with a limiting spring 27 at its upper end. The upper ends of the multiple limiting springs 27 are all set on the inner wall of the mounting sleeve 25. The multiple limiting springs 27 can not only enable the mounting cover 2 to move the filter frame 9, but also enable the filter frame 9 to return to its original position.
[0047] See Figure 1-6 When using a multi-stage fume filtration purifier to filter and purify impurities and harmful substances in textile printing and dyeing fumes, firstly, an appropriate amount of washing liquid needs to be poured into the bottom of the purification box 1. Then, the fan 3 and drive motor 21 are started. The fan 3 will guide the textile printing and dyeing fumes into the bottom of the purification box 1 through the ventilation pipe 5. The textile printing and dyeing fumes will enter the washing liquid and mix with it. When the drive motor 21 starts, its output end will drive the drive shaft 7 to rotate. The drive shaft 7 will drive multiple positioning shafts 17 and multiple stirring rods 18 through the fixing plate 16. The rotation, in conjunction with the mounting wheel 19 and multiple positioning wheels 20, allows the textile printing and dyeing fumes to be fully mixed with the washing liquid. This not only cools the textile printing and dyeing fumes but also effectively removes impurities and harmful substances. The textile printing and dyeing fumes exiting the washing liquid pass through the upper filter plate 8 and filter frame 9. The adsorption components 22 within the filter plate 8 and filter frame 9 further filter and purify the impurities and harmful substances in the textile printing and dyeing fumes, ensuring the effective filtration and purification of impurities and harmful substances in the textile printing and dyeing fumes.
