Description

Technical Field

[0001] This invention belongs to the field of iron-carbon micro-electrolysis Fenton oxidation technology, specifically an iron-carbon micro-electrolysis Fenton oxidation device. Background Technology

[0002] In the wastewater treatment process, after conventional treatment, the wastewater needs to be further treated in an iron-carbon micro-electrolysis Fenton oxidation device. The raw wastewater, after conventional treatment, enters the water distribution chamber at the bottom of the iron-carbon micro-electrolysis Fenton oxidation reactor. After passing through the packing material, it enters the effluent clarification zone at the top of the reactor, and then is discharged through the drain outlet to enter the sedimentation process, thus completing the treatment. However, the packing material is generally replaced manually, which presents the following problems:

[0003] First, removing the packing material from the side takes a long time; second, even after removal, some packing material remains on the water distribution plate, resulting in incomplete cleaning; finally, the replaced packing material is not tight enough and is prone to loosening under the impact of fluid, thus reducing its effectiveness. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides an iron-carbon micro-electrolysis Fenton oxidation device, which effectively solves the problem that the filler is generally replaced manually during the replacement process, resulting in long replacement time and inconvenience due to the need for manual operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an iron-carbon micro-electrolysis Fenton oxidation device, comprising a housing, wherein an upper water distribution sieve plate is fixedly arranged inside the housing and a lower water distribution sieve plate is movably arranged. The housing is formed from bottom to top through the upper and lower water distribution sieve plates into a water distribution chamber, a filling chamber, and a clarification chamber. The outer wall of the filling chamber is provided with a filling port, and a sealing mechanism is provided on the filling port. An auxiliary material changing mechanism is provided above the lower water distribution sieve plate. The auxiliary material changing mechanism includes a power component, a hollow rotating shaft, and an adjusting component. The power component is fixedly arranged on the outer wall of the housing and drives the hollow rotating shaft to rotate. The hollow rotating shaft is rotatably arranged inside the filling chamber, and rods are uniformly rotatably arranged on the hollow rotating shaft. A lever plate is fixedly arranged at both ends of each rod. The adjusting component is fixedly arranged on the outer wall of the housing and is used to adjust the angle of the lever plate.

[0006] Preferably, the lower water distribution screen plate is rotatably connected to the packing cavity on both sides of the middle via pins, and a first flexible plate and a second flexible plate are fixedly arranged at both ends of the lower water distribution screen plate. The first flexible plate is fixedly arranged on the inner bottom wall of the packing inlet, and the second flexible plate is fixedly arranged inside the packing cavity.

[0007] Preferably, a support is fixedly provided at each corner of the packing cavity, a guide post is fixedly provided on each support, a support spring is surrounded on each guide post, and each support spring is abutted against the lower water distribution screen plate.

[0008] Preferably, the power component includes a motor frame fixedly mounted on the outer wall of the housing, a power motor fixedly mounted on the motor frame, a first gear fixedly mounted on the output shaft of the power motor, the first gear meshing with a second gear, and the second gear fixedly mounted on a hollow rotating shaft.

[0009] Preferably, the adjusting component includes two thumb cylinders fixedly mounted on the outer wall of the housing. The output ends of the two thumb cylinders are jointly fixedly mounted on a mounting plate. A connecting rod is fixedly mounted on the mounting plate. A cylinder is rotatably mounted on the connecting rod. The cylinder is movably mounted inside a hollow rotating shaft. A rack is fixedly mounted on the cylinder. A reversing gear is fixedly mounted in the middle of the rod. The reversing gear meshes with the rack.

[0010] Preferably, the rack is located inside the hollow rotating shaft and slides with it, and the longitudinal cross-section of the side of the rack away from the reversing gear is arc-shaped.

[0011] Preferably, the sealing mechanism includes two electric push rods fixedly mounted on the outer wall of the box. The output ends of the two electric push rods are each fixedly mounted with a connecting seat. The two connecting seats are fixedly mounted with the sealing plate, and the sealing plate is sealed to the filling port.

[0012] Preferably, the outer wall of the box is fixedly provided with an upper storage box and a lower receiving box, wherein the interior of the upper storage box is fixedly connected to the top of the filling chamber through a discharge pipe with a valve, and the lower receiving box is located directly below the filling port.

[0013] Preferably, both sides of the filling port are provided with strip grooves, and elastic sealing strips are fixedly embedded in the interior of both strip grooves. The two elastic sealing strips are respectively fixed to both sides of the first flexible plate and connected as one unit. The interior of the elastic sealing strip forms a vertical groove, and the interior of the first flexible plate forms a horizontal groove. The vertical grooves in the two elastic sealing strips are connected through the horizontal groove in the first flexible plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1) During operation, the auxiliary material changing mechanism can drive the hollow shaft to rotate through the power component during the replacement of the packing. The hollow shaft then drives the actuating plate to rotate. On the one hand, the actuating plate speeds up the falling of the packing, and on the other hand, it can also make the lower water distribution screen plate shake, thereby preventing too much packing from remaining on the surface of the lower water distribution screen plate.

[0016] 2) During operation, the adjustable parts can be used to adjust the angle of the agitator plate during the filling process, so that the agitator plate experiences minimal resistance during rotation. This allows the lower water distribution screen plate to vibrate, resulting in a more compact filling and improved filling effect.

[0017] 3) During operation, through the combined use of the elastic sealing strip and the first flexible plate, when the sealing plate in the sealing mechanism squeezes the first flexible plate, the liquid in the horizontal groove enters the vertical groove in the elastic sealing strip, thereby ensuring the contact pressure between the elastic sealing strip and the sealing plate to improve the sealing performance.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Depend on Figure 1-9 Give;

[0032] Reference Figure 1 The existing device includes a booster pump 20, a mixer 21, a hydrogen peroxide dosing device 22, and an iron-carbon micro-electrolysis Fenton oxidation reactor 19. The iron-carbon micro-electrolysis Fenton oxidation reactor 19 has a sludge discharge port 23 and a liquid discharge port 24 distributed at the upper and lower ends on the same side. The iron-carbon micro-electrolysis Fenton oxidation reactor 19 has two water distribution plates 25 inside. The interior of the two water distribution plates 25 is filled with a packing mixture 26 containing iron and activated carbon. A material exchange port 27 is formed on the side of the space where the packing mixture 26 is located, so that the staff can replace the packing mixture 26 through the material exchange port 27.

[0033] During operation, the raw wastewater undergoes conventional treatment and then enters the mixer 21 via the booster pump 20. Simultaneously, materials are added into the mixer 21 via the hydrogen peroxide dosing device 22. The mixed materials then enter the water distribution chamber at the bottom of the iron-carbon micro-electrolysis Fenton oxidation reactor 19 through a pipeline. Finally, after passing through the packing mixture 26, the materials enter the effluent clarification zone at the top of the iron-carbon micro-electrolysis Fenton oxidation reactor 19. Subsequently, the materials are discharged through the drain port 24 and enter the sedimentation process, thus completing the treatment process.

[0034] However, the packing mixture 26 inside is usually replaced manually during the replacement process, which results in a long replacement time and requires manual operation, making it inconvenient.

[0035] Reference Figure 2-8 This invention relates to an apparatus for iron-carbon micro-electrolysis Fenton oxidation, comprising a housing 1. An upper water distribution sieve plate 2 is fixedly installed inside the housing 1, and a lower water distribution sieve plate 3 is movably installed. The interior of the housing 1, through the upper and lower water distribution sieve plates 2 and 3, sequentially forms a water distribution chamber 4, a packing chamber 5, and a clarification chamber 6 from bottom to top. The outer wall of the packing chamber 5 has a packing inlet 7, and a sealing mechanism 8 is provided on the packing inlet 7. An auxiliary material changing mechanism 9 is provided above the lower water distribution sieve plate 3. The auxiliary material changing mechanism 9 includes a power component 10, a hollow rotating shaft 11, and an adjusting component 14. The power component 10 is fixedly installed on the outer wall of the housing 1 and drives the hollow rotating shaft 11 to rotate. The hollow rotating shaft 11 is rotatably installed inside the packing chamber 5, and rods 12 are evenly rotatably installed on the hollow rotating shaft 11. Actuating plates 13 are fixedly installed at both ends of each rod 12. The adjusting component 14 is fixedly installed on the outer wall of the housing 1 and used to adjust the angle of the actuating plates 13.

[0036] With this design, when the packing material in the packing cavity 5 needs to be replaced during use, the sealing mechanism 8 is used to open the packing port 7. The packing material in the packing cavity 5 can then fall through the packing port 7 under gravity. During this process, the power component 10 drives the hollow rotating shaft 11 to rotate. The hollow rotating shaft 11 drives the actuating plate 13 to rotate through the rod 12. At this time, the actuating plate 13 is parallel to the hollow rotating shaft 11, and the contact area between the actuating plate 13 and the packing material is at its maximum. The rotation of the actuating plate 13 can accelerate the falling of the packing material. During this process, the actuating plate 13 will also continuously squeeze the lower water distribution screen plate 3, causing the lower water distribution screen plate 3 to shake continuously, further accelerating the falling process of the packing material.

[0037] The lower water distribution screen plate 3 is rotatably mounted to the filling cavity 5 on both sides of the middle via pins. A first flexible plate 301 and a second flexible plate 302 are fixedly mounted at both ends of the lower water distribution screen plate 3. The first flexible plate 301 is fixedly mounted on the inner bottom wall of the filling port 7, and the second flexible plate 302 is fixedly mounted inside the filling cavity 5. A support 303 is fixedly mounted at each corner of the filling cavity 5. A guide post 304 is fixedly mounted on each support 303. A support spring 305 is wrapped around each guide post 304. Each support spring 305 abuts against the lower water distribution screen plate 3.

[0038] With this design, when the actuating plate 13 continuously presses the lower water distribution screen plate 3, the lower water distribution screen plate 3 will vibrate back and forth around the position of its pin under the action of the support spring 305, thereby accelerating the falling process of the packing; and since the lower water distribution screen plate 3 has a first flexible plate 301 and a second flexible plate 302 distributed at both ends, it can prevent the packing from passing through the lower water distribution screen plate 3.

[0039] The power component 10 includes a motor frame 1001 fixedly mounted on the outer wall of the housing 1, a power motor 1002 fixedly mounted on the motor frame 1001, a first gear 1003 fixedly mounted on the output shaft of the power motor 1002, the first gear 1003 meshing with a second gear 1004, and the second gear 1004 fixedly mounted on the hollow rotating shaft 11.

[0040] This design facilitates the rotation of the first gear 1003 via the power motor 1002, which in turn drives the second gear 1004 to rotate through meshing. The second gear 1004 then drives the hollow shaft 11 to rotate, thus achieving the driving process.

[0041] The adjusting component 14 includes two thumb cylinders 1401 fixedly mounted on the outer wall of the housing 1. The output ends of the two thumb cylinders 1401 are jointly fixedly mounted on a mounting plate 1402. A connecting rod 1403 is fixedly mounted on the mounting plate 1402. A cylinder 1404 is rotatably mounted on the connecting rod 1403. The cylinder 1404 is movably mounted inside the hollow rotating shaft 11. A rack 1405 is fixedly mounted on the cylinder 1404. A reversing gear 1406 is fixedly mounted in the middle of the rod 12. The reversing gear 1406 meshes with the rack 1405.

[0042] With this design, when the angle of the actuating plate 13 needs to be adjusted, the mounting plate 1402 is moved by the thumb cylinder 1401. The mounting plate 1402 moves the cylinder 1404 through the connecting rod 1403. The cylinder 1404 moves the rack 1405 inside the hollow rotating shaft 11. The rack 1405 drives the reversing gear 1406 to rotate through meshing. The reversing gear 1406 drives the actuating plate 13 to rotate through the rod 12, thereby realizing the angle adjustment of the actuating plate 13 for use during the filling process.

[0043] Specifically, the rack 1405 is located inside the hollow rotating shaft 11 and slides with it, and the longitudinal section shape of the side of the rack 1405 away from the reversing gear 1406 is arc-shaped.

[0044] The sealing mechanism 8 includes two electric push rods 801 fixedly installed on the outer wall of the housing 1. Each of the two electric push rods 801 has a connecting seat 802 fixedly installed at its output end. Both connecting seats 802 are fixedly installed with the sealing plate 803. The sealing plate 803 is sealed to the filling port 7.

[0045] This design facilitates the movement of the connecting seat 802 via the electric push rod 801, which in turn moves the sealing plate 803, allowing the filling port 7 to be sealed via the sealing plate 803.

[0046] The outer wall of the box 1 is fixedly provided with an upper storage box 101 and a lower receiving box 102. The interior of the upper storage box 101 is fixedly connected to the top of the inner part of the filling chamber 5 through a discharge pipe with a valve. The lower receiving box 102 is located directly below the filling port 7.

[0047] With this design, after the packing material in the packing cavity 5 has fallen, the sealing mechanism 8 seals the packing port 7 and opens the valve, allowing the packing material in the upper storage box 101 to fall into the packing cavity 5. The angle of the actuating plate 13 is adjusted by the adjusting component 14 so that the actuating plate 13 is perpendicular to the hollow rotating shaft 11. At this time, the resistance encountered by the actuating plate 13 when rotating is minimal. The rotation of the actuating plate 13 causes the lower water distribution screen plate 3 to shake continuously, so that the packing material in the packing cavity 5 is more compacted and the filling effect is improved.

[0048] Furthermore, strip grooves 15 are provided on both sides of the filling port 7, and elastic sealing strips 16 are fixedly embedded in the interior of the two strip grooves 15. The two elastic sealing strips 16 are respectively fixed on both sides of the first flexible plate 301 and connected as one. The interior of the elastic sealing strip 16 forms a vertical groove 17, and the interior of the first flexible plate 301 forms a horizontal groove 18. The vertical grooves 17 in the two elastic sealing strips 16 are connected through the horizontal grooves 18 in the first flexible plate 301.

[0049] With this design, when the sealing plate 803 in the sealing mechanism 8 squeezes the first flexible plate 301, the liquid in the horizontal groove 18 enters the vertical groove 17 in the elastic sealing strip 16, thereby ensuring that the elastic sealing strip 16 maintains the contact pressure with the sealing plate 803 to improve the sealing performance.
