Description

Technical Field

[0001] This utility model relates to the field of peroxide purification technology, and in particular to an activated carbon filtration device for peroxide purification. Background Technology

[0002] Peroxides are compounds containing the peroxide group (-OO-), and can be considered derivatives of hydrogen peroxide. Their characteristic feature is the presence of peroxide ions in the molecule. Peroxides are classified into inorganic and organic peroxides. Peroxides play an important role in the textile and bleaching industries. Many chemical reactions and industrial production processes have strict requirements on the purity of peroxides. For example, peroxides used in semiconductor cleaning and etching in the electronics industry require extremely high purity to prevent impurities from contaminating and damaging electronic components. Activated carbon, with its highly developed pore structure and large specific surface area, possesses a strong adsorption capacity. It can adsorb pigments, odor substances, and some organic impurities from peroxides, thereby achieving purification.

[0003] Currently, when using activated carbon to purify and filter peroxides, most peroxides are in liquid form, and the activated carbon is in a static state. In a static state, the solution around the activated carbon easily forms a concentration gradient. As adsorption proceeds, the concentration of impurities near the surface of the activated carbon decreases, and the adsorption rate gradually slows down. This results in a longer time required to purify the same amount of peroxide, thus reducing the purification efficiency of peroxides. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that activated carbon in a static state prolongs the filtration time when purifying and filtering peroxides, and to propose a peroxide purification activated carbon filtration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A peroxide purification activated carbon filtration device includes a processing tank and a feed pipe fixedly installed on the processing tank. A filter tube for holding activated carbon is fixedly installed inside the processing tank. A filter plate is slidably connected inside the filter tube. The device also includes a rotating cylinder rotatably connected inside the filter tube. Multiple stirring rods are fixedly connected around the outer wall of the rotating cylinder. A driving component for driving the rotating cylinder to rotate is provided between the filter plate and the rotating cylinder.

[0007] Preferably, the top of the filter tube is fixedly connected to a feed hopper that communicates with the feed pipe, and the bottom wall of the treatment tank is fixedly connected to a discharge pipe.

[0008] Preferably, a plurality of fixed rods are fixedly connected to the inner wall of the treatment tank, the filter tube is fixedly connected to the plurality of fixed rods, a plurality of telescopic rods are fixedly connected to the lower wall of the treatment tank, and the filter plate is fixedly connected to the plurality of telescopic rods.

[0009] Preferably, a guide plate is fixedly connected to the inner wall of the processing tank, a sliding rod is slidably connected to the guide plate, and a first spring is sleeved on the sliding rod, with the two ends of the first spring fixedly connected to the guide plate and the sliding rod respectively.

[0010] Preferably, an installation plate is fixedly placed on the outside of the processing tank, a servo motor is fixedly installed on the installation plate, a rotating rod is fixedly connected to the output end of the servo motor, one end of the rotating rod extends into the processing tank and is rotatably connected to the processing tank, and a cam is fixedly connected to the rotating rod.

[0011] Preferably, the slide rod abuts against the cam, and each of the stirring rods has a groove at its bottom, with a second spring fixedly connected to the top wall of the groove of each stirring rod.

[0012] Preferably, an adjusting rod is fixedly connected to the bottom of each of the second springs, the end of the adjusting rod away from the second spring abuts against the filter plate, and each adjusting rod is slidably connected in the groove of the stirring rod.

[0013] Preferably, a plurality of strip rods are fixedly connected to the inner wall of the filter tube, and bearing plates are fixedly connected to the plurality of strip rods, with the rotating drum rotatably connected to the bearing plates.

[0014] Preferably, the driving component includes an insert rod fixedly connected to the top of the filter plate, a driving rod fixedly connected to the insert rod, a spiral groove corresponding to the driving rod being formed on the inner wall of the rotating drum, and an elastic sealing gasket fixedly connected to the bottom of the rotating drum.

[0015] Compared with the prior art, this utility model provides a peroxide purification activated carbon filtration device, which has the following beneficial effects:

[0016] 1. This peroxide purification activated carbon filtration device, as the filter plate moves upward, drives the insertion rod and drive rod to slide upward automatically inside the rotating drum. The drive rod slides along the spiral groove of the rotating drum, causing the drum to rotate. The rotating drum drives multiple stirring rods to rotate simultaneously, which in turn stirs the activated carbon in the filter tube. This periodic movement of the static activated carbon increases the contact area with the peroxide solution, promotes mass transfer efficiency, and allows for faster and more uniform adsorption of impurities. It also reduces local adsorption saturation and activated carbon accumulation and clogging, thereby improving the purification effect and filtration efficiency.

[0017] 2. This peroxide purification activated carbon filtration device, by starting a servo motor, can drive a rotating rod to rotate. The rotating rod drives a cam to rotate, and the cam's protrusion reciprocates against the slide rod, causing the filter plate to move upwards and vibrate. The filter plate at the bottom of the activated carbon moves up and down and vibrates. Through mechanical disturbance, the activated carbon particles are kept in a loose state, increasing the dynamic contact area with the peroxide solution. At the same time, it effectively prevents particles from accumulating and clogging the filter pores, thereby improving the impurity adsorption efficiency, reducing filtration resistance, and avoiding local adsorption saturation, ultimately achieving a more uniform and efficient purification and filtration effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0030] Reference Figures 1-9 A peroxide purification activated carbon filtration device includes a processing tank 1 and a feed pipe 2 fixedly installed on the processing tank 1. A filter pipe 3 for holding activated carbon is fixedly installed inside the processing tank 1. A filter plate 4 is slidably connected inside the filter pipe 3. The device also includes a rotating cylinder 5 rotatably connected inside the filter pipe 3. Multiple stirring rods 6 are fixedly connected around the outer wall of the rotating cylinder 5. A driving component 7 is provided between the filter plate 4 and the rotating cylinder 5 to drive the rotating cylinder 5 to rotate. The driving component 7 can make the rotating cylinder 5 rotate forward and backward. The rotating cylinder 5 drives the multiple stirring rods 6 to rotate simultaneously, thereby driving the multiple stirring rods 6 to stir the activated carbon inside the filter pipe 3. This causes the static activated carbon to move periodically. The periodically stirred activated carbon increases the contact area with the peroxide solution, promotes mass transfer efficiency, and can more quickly and uniformly adsorb impurities, reducing local adsorption saturation and activated carbon accumulation and clogging, thereby improving the purification effect and filtration efficiency. It should be noted that the filter pipe 3 is filled with activated carbon for purifying and filtering peroxides.

[0031] The top of the filter tube 3 is fixedly connected to the feed hopper 8, which is connected to the feed pipe 2. The bottom wall of the treatment tank 1 is fixedly connected to the discharge pipe 9. Peroxide can be added into the feed hopper 8 through the feed pipe 2, and then enter the filter tube 3 from the feed hopper 8 to contact the activated carbon for purification and filtration.

[0032] Multiple fixed rods 10 are fixedly connected to the inner wall of the treatment tank 1. The filter tube 3 is fixedly connected to the multiple fixed rods 10. Multiple telescopic rods 11 are fixedly connected to the lower wall of the treatment tank 1. The filter plate 4 is fixedly connected to the multiple telescopic rods 11. The multiple fixed rods 10 can support the filter tube 3, and the multiple telescopic rods 11 can provide stable support for the filter plate 4, so that the filter plate 4 can slide up and down on the telescopic rods 11.

[0033] A guide plate 12 is fixedly connected to the inner wall of the processing tank 1. A sliding rod 13 is slidably connected to the guide plate 12. A first spring 14 is sleeved on the sliding rod 13. The two ends of the first spring 14 are fixedly connected to the guide plate 12 and the sliding rod 13, respectively.

[0034] A mounting plate 15 is fixedly placed on the outside of the processing tank 1. A servo motor 16 is fixedly mounted on the mounting plate 15. A rotating rod 17 is fixedly connected to the output end of the servo motor 16. One end of the rotating rod 17 extends into the processing tank 1 and is rotatably connected to the processing tank 1. A cam 18 is fixedly connected to the rotating rod 17.

[0035] The slide rod 13 abuts against the cam 18. Starting the servo motor 16 drives the rotating rod 17 to rotate, which in turn drives the cam 18 to rotate. When the protrusion of the cam 18 abuts against the slide rod 13, the slide rod 13 slides upwards on the guide plate 12. Simultaneously, the first spring 14 is compressed. As the slide rod 13 slides upwards, it abuts against the filter plate 4, causing the filter plate 4 to slide upwards and vibrate slightly. When the protrusion of the cam 18 disengages from the slide rod 13, the slide rod 13 automatically returns to its original position under the action of the first spring 14. Then the protrusion... The protrusion of wheel 18 contacts the slide bar 13 again, causing the slide bar 13 to contact the filter plate 4 again. The protrusion of cam 18 repeatedly contacts the slide bar 13, causing the filter plate 4 to move upward and vibrate. The filter plate 4 at the bottom of the activated carbon moves up and down and vibrates. Through mechanical disturbance, the activated carbon particles are kept in a loose state, increasing the dynamic contact area with the peroxide solution. At the same time, it effectively prevents particles from accumulating and clogging the filter pores, thereby improving the impurity adsorption efficiency, reducing filtration resistance and avoiding local adsorption saturation, and finally achieving a more uniform and efficient purification and filtration effect.

[0036] Each stirring rod 6 has a groove at its bottom, and a second spring 19 is fixedly connected to the top wall of the groove of each stirring rod 6. An adjusting rod 20 is fixedly connected to the bottom of each second spring 19. The end of the adjusting rod 20 away from the second spring 19 abuts against the filter plate 4. Each adjusting rod 20 is slidably connected in the groove of the stirring rod 6. When the filter plate 4 slides upward, it will drive the adjusting rod 20 to slide upward. The adjusting rod 20 slides in the groove of the stirring rod 6 by squeezing the second spring 19, so that when the stirring rod 6 rotates, even if the filter plate 4 moves upward, it will not interfere with the rotation of the stirring rod 6.

[0037] Multiple strip rods 21 are fixedly connected to the inner wall of the filter tube 3. Bearing plates 22 are fixedly connected to the multiple strip rods 21. The rotating drum 5 is rotatably connected to the bearing plate 22. The bearing plate 22 can be fixed by the strip rods 21. The bearing plate 22 plays a stable supporting role for the rotating drum 5, so that the rotating drum 5 can rotate stably.

[0038] The driving component 7 includes an insert rod 23 fixedly connected to the top of the filter plate 4, a driving rod 24 fixedly connected to the insert rod 23, a spiral groove 25 corresponding to the driving rod 24 on the inner wall of the rotating drum 5, and an elastic sealing gasket 26 fixedly connected to the bottom of the rotating drum 5. When the filter plate 4 moves upward, it will drive the insert rod 23 and the driving rod 24 to slide upward automatically inside the rotating drum 5. The driving rod 24 will slide along the spiral groove 25 of the rotating drum 5, causing the rotating drum 5 to rotate. The elastic sealing gasket 26 can prevent peroxide from entering the rotating drum 5, thus playing a blocking role.

[0039] In this invention, during use, the servo motor 16 is started, and peroxide is added through the feed pipe 2 into the feed hopper 8. The peroxide then enters the filter pipe 3, contacts the activated carbon, and after being adsorbed by the activated carbon, the peroxide falls through the filter plate 4 to the discharge pipe 9 at the bottom of the treatment tank 1 for subsequent collection. The servo motor 16 drives the rotating rod 17 to rotate, simultaneously driving the cam 18 to rotate. When the protrusion of the cam 18 abuts against the slide rod 13, the slide rod 13 slides upward on the guide plate 12, and at the same time, the first spring 14 is compressed. As the slide rod 13 slides upward, it abuts against the filter plate 4, causing the filter plate 4 to slide upward and also vibrate. Simultaneously, the filter plate 4 drives the insertion rod 23 and the drive rod 24 to move upward inside the rotating drum 5. The drive rod 24 slides on the spiral groove 25, causing the rotating drum 5 to rotate. The rotation of the rotating drum 5 drives multiple stirring rods 6 to rotate, subsequently... When the protrusion of cam 18 disengages from slide rod 13, slide rod 13 automatically resets under the action of the first spring 14. Filter plate 4 automatically resets downwards under the gravity of activated carbon and peroxide, and drive rod 24 automatically moves downwards, causing drum 5 to rotate in the opposite direction. This drives stirring rod 6 to rotate in the opposite direction simultaneously, causing the stationary activated carbon to move periodically. The periodically stirred activated carbon increases the contact area with the peroxide solution, promotes mass transfer efficiency, and can more quickly and uniformly adsorb impurities, reducing local adsorption saturation and activated carbon accumulation and clogging, thereby improving purification effect and filtration efficiency. Furthermore, the reciprocating up-and-down movement and vibration of filter plate 4 at the bottom of the activated carbon mechanically disturbs the activated carbon particles, increasing the dynamic contact area with the peroxide solution. This effectively prevents particle accumulation and clogging of filter pores, thereby improving impurity adsorption efficiency, reducing filtration resistance, and avoiding local adsorption saturation, ultimately achieving a more uniform and efficient purification and filtration effect.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
