Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically a catalytic oxidation device for removing organic pollutants from industrial wastewater. Background Technology
[0002] Industrial wastewater includes production wastewater, industrial sewage, and cooling water. It refers to the wastewater and waste liquid generated during industrial production processes, containing industrial raw materials, intermediate products, by-products, and pollutants generated during production that are lost with the water. Industrial wastewater is diverse and complex in composition, but it generally contains a large amount of organic pollutants.
[0003] The treatment of organic wastewater in industrial wastewater is complex, requiring multiple treatment steps to work together. These include pretreatment stages such as bar filtration and coagulation sedimentation, catalytic oxidation, and post-treatment stages such as sludge dewatering. The most crucial step is catalytic oxidation. However, in existing catalytic oxidation devices, the ozone emitted from the aeration holes cannot effectively dissolve in the wastewater, resulting in low catalytic oxidation efficiency of organic matter. Therefore, further improvements are needed. Utility Model Content

A treatment box is rotatably mounted on the upper end of the treatment base via a rotary seat. U-shaped frames are symmetrically mounted on both sides of the upper end of the treatment box. An aeration shaft is rotatably mounted on the U-shaped frames. The aeration shaft has a hollow internal structure. An aeration cylinder is fixedly connected to the bottom of the aeration shaft and is located inside the treatment box. A limit groove is provided horizontally on the U-shaped frames. A limit block is slidably mounted inside the limit groove. A shearing shaft is rotatably mounted on the limit block. A shearing mechanism is provided between the shearing shaft and the aeration shaft. The treatment base also includes an aeration mechanism. The device further includes a drive mechanism for driving the movement of the treatment box and the shearing mechanism.
[0007] As an improvement of this utility model: the aeration mechanism includes an aerator installed on the treatment base, an aeration pipe connected to the aerator, an air inlet cylinder connected to the aeration pipe, the air inlet cylinder being installed on a U-shaped frame and rotatably arranged with the aeration shaft, a plurality of air inlet holes being connected to the aeration shaft located inside the air inlet cylinder, and a plurality of aeration holes being provided through the aeration cylinder.
[0008] As an improvement of this utility model: the shearing mechanism includes an eccentrically mounted drive gear on the aeration shaft, a driven gear fixed on the shearing shaft meshing with the drive gear on the outside, an eccentric protrusion coaxially fixedly mounted on the bottom of the drive gear, an eccentric frame sleeved on the outside of the eccentric cam, the end of the eccentric frame away from the eccentric protrusion being hinged to the shearing shaft, and multiple shearing blades fixedly mounted on the outer wall of the shearing shaft.
[0009] As an improvement of this utility model: the driving mechanism includes a driving shaft that is vertically rotatably mounted on the processing seat, a driving gear that is fixedly mounted on the driving shaft, the driving gear meshing with a driving gear ring fixed on the outer wall of the processing box, a driving motor that is also mounted at the bottom of the processing seat, the output end of the driving motor being connected to the driving shaft, and the driving mechanism also includes a driving component.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0028] Example 1: See Figures 1-6 In this embodiment of the present invention, a catalytic oxidation device for removing organic pollutants from industrial wastewater includes a treatment base 1. A treatment box 6 is rotatably mounted on the upper end of the treatment base 1 via a rotary seat 16. U-shaped frames 7 are symmetrically mounted on both sides of the upper end of the treatment box 6. An aeration shaft 21 is rotatably mounted on the U-shaped frame 7. The aeration shaft 21 has a hollow internal structure, thereby realizing the flow of ozone gas inside the aeration shaft 21. An aeration cylinder 17 is fixedly connected to the bottom of the aeration shaft 21 and is located inside the treatment box 6. A limiting groove 19 is provided horizontally on the U-shaped frame 7. A limiting block 23 is slidably mounted inside the limiting groove 19. A shearing shaft 18 is rotatably mounted on the limiting block 23. A shearing mechanism is provided between the shearing shaft 18 and the aeration shaft 21. The treatment base 1 is also provided with an aeration mechanism. It also includes a driving mechanism for driving the treatment box 6 and the shearing mechanism.
[0029] The aeration mechanism in this device includes an aerator 3 installed on the treatment base 1. An aerator pipe 4 is connected to the aerator 3. An air inlet cylinder 13 is connected to the aerator pipe 4. The air inlet cylinder 13 is installed on the U-shaped frame 7 and is rotatably arranged with the aerator shaft 21. Multiple air inlet holes 29 are connected to the aerator shaft 21 located inside the air inlet cylinder 13. Multiple aerator holes 22 are provided through the aerator cylinder 17.
[0030] Ozone gas is generated by aerator 3, then enters the air inlet cylinder 13 through aeration pipe 4, and is then guided into the aeration shaft 21 by air inlet 29. Finally, it is sprayed into the industrial wastewater located inside the treatment tank 6 through aeration hole 22.
[0031] The shearing mechanism in this device includes a drive gear 26 eccentrically mounted on the aeration shaft 21, a driven gear 25 fixed on the shearing shaft 18 meshing with the outside of the drive gear 26, an eccentric protrusion 28 coaxially fixedly mounted on the bottom of the drive gear 26, an eccentric frame 27 sleeved on the outside of the eccentric cam, and the end of the eccentric frame 27 away from the eccentric protrusion 28 hinged to the shearing shaft 18. Multiple shearing blades 20 are fixedly mounted on the outer wall of the shearing shaft 18.
[0032] During the rotation of the aeration shaft 21, the drive gear 26 and the eccentric protrusion 28 will rotate synchronously. Due to the action of the eccentric frame 27, the drive gear 26 and the driven gear 25 will always be in a meshing state. In addition, due to the eccentric setting of the eccentric protrusion 28, the distance between the aeration shaft 21 and the shear shaft 18 will always change. Finally, the shear shaft 18 will drive the multiple shear blades 20 to rotate while continuously reciprocating in the radial position of the treatment box 6.
[0033] The drive mechanism in this device includes a drive shaft 9 that is vertically rotatably mounted on the processing seat 1. A drive gear 14 is fixedly mounted on the drive shaft 9. The drive gear 14 meshes with a drive gear ring 8 that is fixed on the outer wall of the processing box 6. A drive motor 15 is also mounted at the bottom of the processing seat 1. The output end of the drive motor 15 is connected to the drive shaft 9. The drive mechanism also includes a drive assembly.
[0034] The drive assembly includes a drive pulley 10 fixed to the top of the drive shaft 9, and a driven pulley 12 mounted on the outside of the drive pulley 10 via a belt 11. The driven pulley 12 is fixed to the top of the aeration shaft 21.
[0035] Start the drive motor 15 to make the drive shaft 9 rotate. On the one hand, under the action of the drive gear 14 and the drive gear ring 8, the treatment box 6 will rotate in the opposite direction to the drive shaft 9. On the other hand, with the cooperation of the drive pulley 10, the belt 11 and the driven pulley 12, the aeration shaft 21 will move in the same direction as the drive shaft 9. Finally, the rotation direction of the treatment box 6 and the aeration shaft 21 will be opposite, thereby increasing the dissolution efficiency of ozone bubbles in industrial wastewater.
[0036] In addition, to ensure the effective discharge of industrial wastewater after catalytic oxidation, a drain pipe 5 is installed at the bottom of the treatment tank 6 in a rotating manner.
[0037] Meanwhile, in order to ensure the normal support of the entire catalytic oxidation device, support legs 2 are installed at the four corners of the bottom of the treatment seat 1.
[0038] Example 2: In another embodiment of the present invention, the difference between this embodiment and the above embodiment is that a limiting spring 24 is also installed between the limiting block 23 and the inner wall of the limiting groove 19. By setting the limiting spring 24, the reciprocating linear motion of the limiting block 23 inside the limiting groove 19 is made more stable, further ensuring the reliability of the shearing mechanism.
[0039] In summary, during operation, industrial wastewater is first introduced into the treatment tank 6, then the drive motor 15 is started, and the treatment tank 6 rotates under the action of the drive mechanism, which also drives the shearing mechanism to work. At the same time, the aeration mechanism continuously introduces ozone into the treatment tank 6, thereby ensuring the high-efficiency catalytic oxidation of industrial wastewater.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
