Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, specifically to an ozone oxidation pretreatment device. Background Technology

[0002] Ozone has extremely strong oxidizing power; the method of treating wastewater with ozone is called ozonation, which belongs to the category of chemical oxidation methods. Ozone can quickly and effectively kill bacteria and viruses in water and remove odors. Ozone is also used to treat industrial wastewater, effectively removing many organic and inorganic pollutants from water, and has significant effects on decolorization, deodorization, and sterilization. Compared with biochemical methods and activated carbon adsorption, ozonation has many advantages. It has strong oxidizing power and good purification effect. It can reduce pollutants in wastewater to the allowable discharge concentration in a short time, and can also eliminate carcinogenic halogenated organic precursors in wastewater, degrading pollutants into substances with low toxicity or no harm. It is simple, safe, reliable, and does not produce secondary pollution. However, industrial wastewater from electroplating, detergent manufacturing, and metal surface treatment may contain impurities and insoluble particulate matter, and often contains corresponding nickel metal particles. If appropriate pretreatment is not carried out, these substances may be dangerous when electrolyzed and react with ozone, causing damage to the reaction equipment. Utility Model Content

[0018] Reference Figures 1 to 5As shown, this utility model provides an ozone oxidation pretreatment device, including: a pretreatment device 2, which is connected to an ozone oxidation device 1 via a pipeline. A main filter 7 and a secondary filter 8 are fixedly connected inside the housing 3 of the pretreatment device 2. A set of hydraulic rods 5 are fixedly connected to the upper surface of the housing 3 near the main filter 7 and the secondary filter 8, respectively. The telescopic rods of the hydraulic rods 5 pass through a through hole in the housing 3 and are fixedly connected to a cleaning plate 6. A discharge port 20 is opened at the bottom of the inner cavity of the housing 3, corresponding to the position of the cleaning plate 6. A receiving groove 17 is opened on the side of the discharge port 20. An electric rod 16 is fixedly connected inside the 7th compartment. The telescopic rod of the electric rod 16 is fixedly connected to a sealing plate 19. The sealing plate 19 is slidably connected inside the storage groove 17. The recycling box 18 is connected to the lower surface of the box body 3 relative to the discharge port 20. One end of the inner cavity of the box body 3 is fixedly connected to the main flow plate 9 and the secondary flow plate 13. The main sleeve 10 and the secondary sleeve 14 are fixedly connected inside the box body 3 through the main fixing plate 11 and the secondary fixing plate 15, respectively. The main sleeve 10 is directly opposite the flow port of the main flow plate 9, and the secondary sleeve 14 is directly opposite the flow port of the secondary flow plate 13. Magnetic rods 12 are fixedly connected inside both the main sleeve 10 and the secondary sleeve 14.

[0019] In this embodiment, wastewater is injected into the first end of the inner cavity of the tank 3 through the injection pipe. Before flowing into the ozone oxidation equipment 1, the wastewater passes sequentially through the main filter screen 7, the secondary filter screen 8, the main flow plate 9, and the secondary flow guide plate 13. The main filter screen 7 can filter out larger impurities in the wastewater, while the secondary filter screen 8 can filter out smaller, insoluble particulate matter clumps in the wastewater, thereby enhancing the treatment effect of the pretreatment device 2 on the wastewater. When the wastewater passes through the guide port of the main flow plate 9, it flows through the gaps between the multiple sets of main sleeves 10, thus reducing the amount of wastewater carried. The nickel metal particles in the wastewater can be attracted and attached to the surface of the main sleeve 10 by the magnetic rod 12 installed inside the main sleeve 10, thus achieving preliminary filtration of the nickel metal particles in the wastewater. When the wastewater passes through the guide port of the secondary guide plate 13, the wastewater will impact the corresponding secondary sleeve 14. Therefore, the nickel metal particles in the wastewater will be attracted and attached to the surface of the secondary sleeve 14 by the magnetic rod 12 installed inside the secondary sleeve 14, thus achieving secondary filtration of the nickel metal particles in the wastewater. This effectively improves the filtration effect of the pretreatment device 2 on wastewater and ensures the safety of the ozone oxidation equipment 1 when treating wastewater.

[0020] In a preferred embodiment, the housing 3 has a rectangular parallelepiped structure as a whole, while the rear end of the housing 3 has a frustum-shaped structure. The main filter 7 is fixedly connected to the front end of the inner cavity of the housing 3, and the secondary filter 8 is fixedly connected to the middle of the inner cavity of the housing 3. At the same time, the mesh size of the main filter 7 is larger than that of the secondary filter 8. A set of auxiliary plates 21 are fixedly connected to the bottom of the inner cavity of the housing 3 near the main filter 7 and the secondary filter 8, respectively. The auxiliary plates 21 have a right-angled triangular prism structure.

[0021] In this embodiment, as Figure 2 and Figure 3 The structure at the tail end of the housing 3 helps guide sewage into the ozone oxidation equipment 1. At the same time, the different mesh sizes of the main filter screen 7 and the secondary filter screen 8 enable the pretreatment device 2 to filter impurities of different volumes in the sewage in batches, thereby improving the filtration effect of the sewage and reducing the chance of the main filter screen 7 and the secondary filter screen 8 being blocked.

[0022] In a preferred embodiment, the two sets of through holes on the upper surface of the housing 3 are both cylindrical in shape, and a set of sealing cylinders 22 are fixedly connected to each of the two sets of through holes. The sealing cylinders 22 are cylindrical in shape, and the inner cavity of the sealing cylinders 22 is matched with the size of the extension rod of the hydraulic rod 5. Meanwhile, the cleaning plate 6 fixedly connected to the hydraulic rod 5 is rectangular in shape.

[0023] In this embodiment, as Figure 2 The sealing cylinder 22 is made of soft rubber, and the inner cavity of the sealing cylinder 22 abuts against the telescopic rod of the hydraulic rod 5, thereby effectively enhancing the sealing performance at the connection between the box 3 and the telescopic rod of the hydraulic rod 5.

[0024] In a preferred embodiment, two sets of guide plates 4 are symmetrically connected on both sides of the inner cavity of the housing 3 relative to the cleaning plate 6. Both sets of guide plates 4 are elongated and the end faces of the guide plates 4 are semi-circular. Guide grooves are opened at both ends of the cleaning plate 6 relative to the guide plates 4. The length of the cleaning plate 6 is adapted to the width of the inner cavity of the housing 3. A cleaning brush is fixedly connected to the side of the cleaning plate 6.

[0025] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The guide plate 4 and the guide groove are matched in size, which helps to enhance the stability of the cleaning plate 6 when it moves. The cleaning brushes fixedly connected to the surface of the cleaning plate 6 abut against the water-facing surfaces of the corresponding main filter screen 7 and secondary filter screen 8. Therefore, when the main filter screen 7 and secondary filter screen 8 need to be cleaned, the worker activates the switch of the hydraulic rod 5. The telescopic rod of the hydraulic rod 5 can push the cleaning plate 6 to move up and down in the box 3. Then the cleaning plate 6 can clean the surface of the main filter screen 7 and secondary filter screen 8 with the cleaning brushes. At the same time, the cleaning brushes are made of hard bristles, which can enhance the cleaning effect.

[0026] As a preferred embodiment, the main flow plate 9 has a U-shaped structure, the cross-section of the flow guide in the middle of the main flow plate 9 has an isosceles trapezoidal structure, and two sets of guide plates 23 are symmetrically connected on both sides of the main flow plate 9 near the secondary filter screen 8. At the same time, both sets of guide plates 23 have a right-angled triangular prism structure.

[0027] In this embodiment, as Figure 2 and Figure 3 The structure of the main flow plate 9 and the guide plate 23 allows the sewage to impact the main sleeve 10 within a specific range, thereby helping to improve the adsorption and fixation effect of the main sleeve 10 on nickel metal particles in the sewage and improve the filtration and treatment effect of the sewage.

[0028] In a preferred embodiment, the main fixing plate 11 has an isosceles trapezoidal structure, and the multiple sets of main sleeves 10 fixedly connected to the surface of the main fixing plate 11 are all cylindrical structures, and the adjacent main sleeves 10 are staggered. The magnetic rod 12 fixedly connected inside the main sleeve 10 has a cylindrical structure, and the size of the main sleeve 10 is larger than the size of the secondary sleeve 14.

[0029] In this embodiment, as Figure 2 and Figure 3 The main sleeve 10 is made of stainless steel, which ensures that the magnetic force of the magnetic rod 12 can pass through the main sleeve 10 smoothly to adsorb and fix the nickel metal particles in the sewage. The main sleeve 10 and the magnetic rod 12 can be easily installed and removed. Therefore, when cleaning the nickel metal particles on the surface of the main sleeve 10, it is only necessary to remove the magnetic rod 12 first, so that the surface of the main sleeve 10 loses its magnetic force and the nickel metal particles attached to the surface of the main sleeve 10 can be quickly cleaned. At the same time, the two ends of the main sleeve 10 are fixedly connected to two sets of main fixing plates 11 by bolts, and the main fixing plates 11 are fixedly connected to the inner cavity of the tank 3 by bolts.

[0030] As a preferred embodiment, the secondary guide plate 13 has an overall U-shaped structure. Multiple sets of guide ports are opened at equal intervals from top to bottom on the surface of the secondary guide plate 13. The cross-section of the guide port is an isosceles trapezoidal structure, and the opening size of the guide port near the main guide plate 9 is smaller. At the same time, the secondary fixing plate 15 has a rectangular structure. The fixing plate and the secondary sleeve 14 are combined to form a U-shaped structure. The secondary sleeve 14 has a cylindrical structure, and the number and position of the secondary sleeve 14 correspond one-to-one with the guide ports.

[0031] In this embodiment, as Figure 2 , Figure 3 and Figure 5 The secondary sleeve 14 is made of stainless steel, which allows the magnetic rod 12 inside the secondary sleeve 14 to adsorb and fix nickel metal particles in the sewage. At the same time, the guide port structure of the secondary guide plate 13 reduces the impact force of sewage when it passes through the guide port and impacts the secondary sleeve 14, thereby helping to enhance the adsorption and fixation effect of the secondary sleeve 14 on nickel metal particles in the sewage. The two ends of the secondary sleeve 14 are fixedly connected to the secondary fixing plate 15 by bolts, and the secondary fixing plate 15 is fixedly connected to the inner side of the tank 3 by bolts.

[0032] The ozone oxidation pretreatment equipment of this utility model, through the cooperation of the main filter screen 7, the secondary filter screen 8, the main guide plate 9, the main sleeve 10, the secondary guide plate 13, the secondary sleeve 14 and the magnetic rod 12, enables the pretreatment device 2 to perform corresponding pretreatment on sewage, thereby enhancing the safety of the ozone oxidation equipment 1 when treating sewage. The ozone oxidation equipment 1 adopts a common brand and model on the market. When cleaning the impurities on the surface of the main filter screen 7 and the secondary filter screen 8, the worker starts the switch of the electric rod 16. The telescopic rod of the electric rod 16 drives the fixedly connected sealing plate 19 to reset synchronously, so that the discharge port 20 opens. Therefore, the impurities cleaned in the box 3 can slide down the inclined surface of the auxiliary plate 21 into the corresponding recycling box 18, thereby improving the cleaning efficiency of the pretreatment device 2.
