Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, and in particular to a water treatment device that combines ozone and activated carbon. Background Technology

[0002] Wastewater treatment equipment is a comprehensive device specifically designed to treat various types of wastewater. It is widely used in industry, agriculture, and daily life, aiming to effectively remove harmful substances from wastewater through physical, chemical, or biological methods, so that it meets discharge standards or can be reused.

[0003] Chinese utility model patent CN218188441U discloses a continuous treatment device for industrial wastewater from hazardous activated carbon, including a sedimentation tank, a filter tank placed on one side of the sedimentation tank, a filter box fixedly connected inside the sedimentation tank, a partition fixedly connected to the inner wall of the sedimentation tank, a protective box fixedly connected inside the sedimentation tank, a water pump fixedly installed on the inner wall of the protective box, a protective cover threaded to the top of the filter tank, connecting pipes on both sides of the filter box, a drain pipe connected to one side of the filter box, a baffle fixedly connected to the inner wall of the filter box, the baffle being higher than the drain pipe, filter material for filtration provided on the baffle, and a drain hole penetrating through the baffle.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When using the above-mentioned device, the staff needs to pass the wastewater into the filter box through the card pipe. The filter material in the filter box filters the wastewater. After the initial purification, the wastewater passes through the drain hole on the baffle and is then discharged from the drain pipe. However, the wastewater usually contains a lot of impurities. After long-term use, the impurities are easy to accumulate in the filter box and are difficult to clean, which has a certain impact on the normal use of the filter box. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a water treatment device that combines ozone and activated carbon.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an ozone and activated carbon synergistic water treatment device, comprising a sedimentation tank, a protective frame fixed at the bottom of the sedimentation tank, a baffle fixed inside the protective frame, collection boxes between the baffle and the frame on both sides of the protective frame, an ozone generator on one side of the sedimentation tank, and openings at the top of the collection boxes and on the side of the collection boxes near the ozone generator. A cover plate for covering the openings at the top of the two collection boxes is fixed to the top of the protective frame, and a conveying mechanism for conveying wastewater is provided on the top of the cover plate. The conveying mechanism includes a main pipe connected to an external wastewater storage system and a branch pipe connected to the main pipe through a T-junction. A solenoid valve for controlling the opening and closing of the branch pipe is provided on the branch pipe. The end of the branch pipe away from the main pipe passes through the top of the cover plate and is fixed. A first filter screen for covering the opening is provided on the side of the collection box near the ozone generator. A conveying component for conveying filtered wastewater to the ozone generator is provided in the sedimentation tank.

[0007] By adopting the above technical solution, when treating wastewater, staff need to open the solenoid valve so that the external wastewater can enter the collection tank through the main pipe and branch pipe. Then, the wastewater will be preliminarily filtered through the first filter screen on one side of the collection tank and discharged into the sedimentation tank. The filtered wastewater will be transported to the ozone generator through the transmission component. The ozone generated by the ozone generator can decompose the organic matter in the recalcitrant wastewater into easily biodegradable small molecules, improve the biodegradability of the wastewater, and create conditions for subsequent biological treatment. Ozone deep treatment can further remove the pollutants remaining in the wastewater after biological treatment, so that the water quality reaches a higher standard.

[0008] Furthermore, an L-shaped bracket is fixed to the side of the first filter screen near the ozone generator, and a baffle is rotatably installed on the protective frame at the position corresponding to the L-shaped bracket to cooperate with the L-shaped bracket and to fix the first filter screen. A push-pull handle is fixed to the side of the first filter screen near the ozone generator, and a drive mechanism for lifting the collection box is provided on the top of the sedimentation tank.

[0009] By adopting the above technical solution, when staff need to clean and unclog a blocked collection box, they only need to close the solenoid valve on the branch pipe corresponding to the collection box, thereby stopping the wastewater from flowing into the collection box. Then, staff only need to open the baffle that cooperates with the L-shaped bracket, and then pull the push-pull handle by hand or rope, so that the collection box is slowly moved out of the protective frame. Then, the drive mechanism drives the collection box to the top of the sedimentation tank, so that staff can clean the first filter screen inside the collection box and ensure the normal filtration function thereafter.

[0010] Furthermore, the driving mechanism includes a U-shaped mounting plate fixedly installed on the top of the sedimentation tank, a rectangular frame slidably installed between the two sides of the U-shaped mounting plate, a lead screw that passes through the horizontal section of the U-shaped mounting plate and is rotatably connected, and a drive motor fixed to the top of the U-shaped mounting plate and driving the lead screw to rotate. The lead screw passes through the top of the rectangular frame and is threadedly connected.

[0011] By adopting the above technical solution, when workers need to lift the collection box to the top of the sedimentation tank for cleaning or replacement, they first need to start the drive motor, which in turn drives the lead screw connected to it to rotate. Because the circumferential movement of the rectangular frame is restricted by the U-shaped mounting plate, the lead screw drives the rectangular frame connected to it to slide. When the rectangular frame slides from the top of the sedimentation tank to the inner bottom wall of the sedimentation tank, the workers then move the collection box onto the rectangular frame. Next, the workers need to control the motor to rotate in the opposite direction, so that the collection box in the rectangular frame is lifted to the top of the sedimentation tank. Then, the workers clean the debris in the collection box.

[0012] Furthermore, an upper corrugated pipe covering the outside of the lead screw is fixed between the bottom of the horizontal section of the U-shaped mounting plate and the top of the rectangular frame, and a support plate is rotatably mounted on the lower end of the lead screw. A lower corrugated pipe covering the outside of the lead screw is fixed between the top of the support plate and the top of the inner part of the rectangular frame.

[0013] By adopting the above technical solution, when the operator starts the drive motor to move the rectangular frame up and down, the upper corrugated pipe adaptively contracts with the movement of the rectangular frame. Since the lower corrugated pipe is fixed to the top of the rectangular frame and the support plate, and the support plate is rotatably connected to the lower end of the lead screw, the support plate remains relatively stationary during the rotation of the lead screw. This allows the lower corrugated pipe to adaptively contract during the up and down movement of the rectangular frame. During use, the upper and lower corrugated pipes work together to provide good protection for the lead screw, reducing the probability of accelerated corrosion due to exposed lead screws and reducing the probability of debris easily adhering to the exposed lead screws, thus affecting the movement of the rectangular frame.

[0014] Furthermore, the distance between the bottom housing of the drive motor and the top of the U-shaped mounting plate is 5cm. A protective cover covering the outside of the drive motor is fixed on the top of the U-shaped mounting plate. Multiple heat dissipation holes are provided through the side wall of the protective cover. A drain outlet is provided at the intersection between the bottom of the protective cover and the side wall of the protective cover.

[0015] By adopting the above technical solution, the protective cover provides excellent protection for the drive motor, reducing the probability of accelerated aging due to sun and rain exposure. The heat dissipation holes provide good ventilation and heat dissipation during the operation of the drive motor. When a small amount of rainwater enters the protective cover through the heat dissipation holes, the drain outlet at the bottom of the protective cover effectively drains the water, reducing the probability of the drive motor being damaged by rainwater accumulating on the top of the U-shaped mounting plate.

[0016] Furthermore, the height of the bottom of the rectangular frame gradually decreases from the protective frame towards the ozone generator, and a limit strip is fixed at the bottom of the rectangular frame near the ozone generator.

[0017] By adopting the above technical solution, when the staff moves the collection box into the inside of the rectangular frame, the bottom of the collection box fits into the bottom of the rectangular frame, causing the collection box to tilt towards the side closer to the ozone generator. The limiting strip plays a good limiting role for the collection box, ensuring the stability of the collection box as it rises with the rectangular frame.

[0018] Furthermore, a pad is fixed on the side wall of the bottom of the rectangular frame near the collection box, and a rotating roller for assisting the movement of the collection box is rotatably mounted on the top of the pad. Multiple rotating rollers are provided, and the top of each roller is flush with the bottom of the collection box.

[0019] By adopting the above technical solution, when the staff needs to move the collection box to the bottom of the rectangular frame, the staff needs to pull the collection box to the top of the pad. The rotating rod fixed to the top of the pad can effectively reduce the friction on the surface of the collection box and improve the efficiency of the staff in moving the collection box.

[0020] Furthermore, multiple drainage holes are provided through the bottom and side walls of the collection box.

[0021] By adopting the above technical solution, during the process of the collection box being lifted to the top of the sedimentation tank by the drive mechanism, due to the blockage of some mesh holes on the first filter screen and some drainage holes on the collection box, a small amount of water accumulates in the collection box. The remaining drainage holes cooperate and play a good drainage role, reducing the total weight of the collection box and the water inside, and reducing the kinetic energy loss of the drive mechanism during the process of lifting the collection box.

[0022] Furthermore, a pair of fixing plates are fixed on the inner walls of both sides of the sedimentation tank, and a second filter screen is provided between the two pairs of fixing plates on the inner walls of both sides of the sedimentation tank.

[0023] By adopting the above technical solution, when the wastewater is filtered through the first filter screen into the sedimentation tank, the second filter screen filters the filtered wastewater again, reducing the impurity content in the wastewater and improving the purity of the filtered wastewater to a certain extent.

[0024] Furthermore, an activated carbon storage mesh box is fixed in the sedimentation tank near the ozone generator. The activated carbon storage mesh box is filled with activated carbon particles, and the particle size of the activated carbon particles is larger than the mesh size of the activated carbon storage mesh box.

[0025] By employing the above technical solution, activated carbon particles, through their capillary structure and well-developed pore structure, can adsorb impurities such as suspended solids, organic matter, heavy metal ions, and dye molecules in wastewater after secondary purification, significantly reducing the color and turbidity of the water and making it clearer. Furthermore, activated carbon can adsorb odor-causing substances and pigment molecules in the water, removing odors and color, and improving water treatment efficiency.

[0026] The technical advantages of this application compared to the prior art are as follows: When staff need to clean and unclog a blocked collection box, they only need to close the solenoid valve on the branch pipe corresponding to the collection box to stop the wastewater from flowing into the collection box. Then, staff only need to open the baffle that cooperates with the L-shaped bracket, and then pull the push handle by hand or rope to slowly move the collection box out of the protective frame. Subsequently, the drive mechanism will drive the collection box to the top of the sedimentation tank so that staff can clean the first filter screen inside the collection box to ensure normal filtration function.

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Example 1, as Figure 1-6 As shown in the illustration, this application discloses a water treatment device for the synergistic use of ozone and activated carbon, including a sedimentation tank 1, a collection box 22, a conveying mechanism 4, a transmission component 5, and a driving mechanism 6. A protective frame 2 is fixed inside the sedimentation tank 1, and a baffle 21 located in the middle of the protective frame 2 is fixed inside the protective frame 2, dividing the internal space of the protective frame 2 into two separate spaces. The collection box 22 is positioned between the baffle 21 and the frames on both sides of the protective frame 2. Two collection boxes 22 are provided. An ozone generator 3 (ozone generators are commonly used devices in the prior art, and their specific structure and operating principle are existing technologies, which will not be elaborated upon here; for example, an ozone generator of model WY-60G can be selected) is provided on the side of the sedimentation tank 1 away from the collection box 22. The top of the collection box 22 and the side of the collection box 22 near the ozone generator 3 are both open. A first filter screen 24 is provided on the side of the collection box 22 near the ozone generator 3, and the first filter screen 24 is used to cover the opening of the collection box 22 on the side near the ozone generator 3. The top of the protective frame 2 is fixed with a cover plate 23, which covers the openings at the top of the two collection boxes 22.

[0031] A conveying mechanism 4 is located on top of the cover plate 23. The conveying mechanism 4 is used to convey wastewater. Specifically, the conveying mechanism 4 includes a main pipe 41, branch pipes 42, and solenoid valves 43. The main pipe 41 is connected to an external wastewater storage system. The branch pipes 42 are connected to the main pipe 41 via a tee pipe. The end of the branch pipe 42 furthest from the main pipe 41 passes through the top of the cover plate 23 and is fixed. Two branch pipes 42 are provided, each conveying wastewater through the cover plate 23 to one of two collection tanks 22. Two solenoid valves 43 are provided on the branch pipes 42, each controlling the opening and closing of one branch pipe 42. A transmission assembly 5 is located inside the sedimentation tank 1. The transmission assembly 5 is used to transmit the filtered wastewater to the ozone generator 3. The transmission assembly 5 includes a water pump 51, an inlet pipe 52, and an outlet pipe 53. The water pump 51 is fixed on the side wall of the sedimentation tank 1 near the ozone generator 3. One end of the inlet pipe 52 is fixed and connected to the side wall of the sedimentation tank 1, and the other end of the inlet pipe 52 is fixed and connected to the inlet of the water pump 51. The two ends of the outlet pipe 53 are fixed and connected to the outlet of the water pump 51 and the ozone generator 3, respectively.

[0032] When wastewater needs to be treated, the staff needs to open the solenoid valve 43 on the control branch pipe 42, so that the external wastewater enters the collection tank 22 through the main pipe 41 and the branch pipe 42. Then, the wastewater will be preliminarily filtered through the first filter screen 24 on one side of the collection tank 22 and discharged into the sedimentation tank 1. The filtered wastewater is transported to the ozone generator 3 by the water pump 51. The ozone generated by the ozone generator 3 can decompose the organic matter in the recalcitrant wastewater into small molecules that are easily biodegradable, improve the biodegradability of the wastewater, and create conditions for subsequent biological treatment. Ozone deep treatment can further remove the pollutants remaining in the wastewater after biological treatment, so that the water quality reaches a higher standard.

[0033] To ensure the stability of the collection box 22 during use, an L-shaped bracket 25 is fixed to the side of the first filter 24 near the ozone generator 3. A baffle 26 is rotatably installed on the L-shaped bracket 25 at the position corresponding to the protective frame 2. The baffle 26 cooperates with the L-shaped bracket 25 and is used to fix the first filter 24. In this embodiment, a push-pull handle 27 is fixed to the side of the first filter 24 near the ozone generator 3.

[0034] To lift the collection box 22 to the top of the sedimentation tank 1 for cleaning or replacement, a drive mechanism 6 is installed at the top of the sedimentation tank 1. The drive mechanism 6 includes a U-shaped mounting plate 61, a rectangular frame 62, a lead screw 63, and a drive motor 64. The U-shaped mounting plate 61 is fixedly installed at the top of the sedimentation tank 1, and the rectangular frame 62 is slidably installed between the two sides of the U-shaped mounting plate 61. The lead screw 63 passes through the horizontal section of the U-shaped mounting plate 61 and is rotatably connected. The lead screw 63 also passes through the top of the rectangular frame 62 and is threadedly connected. The drive motor 64 is fixed to the top of the U-shaped mounting plate 61, and the output shaft of the drive motor 64 is fixed to the upper end of the lead screw 63.

[0035] When it is necessary to clean the collection box 22, the staff only needs to close the solenoid valve 43 on the branch pipe 42 corresponding to the collection box 22, so that the wastewater in the branch pipe 42 stops flowing into the collection box 22. Then, the staff only needs to open the baffle 26 that cooperates with the L-shaped bracket 25. Then, the staff can pull the push-pull handle 27 by hand or rope and other tools to slowly move the collection box 22 out of the protective frame 2. Then, the drive motor 64 needs to be turned on. The drive motor 64 drives the lead screw 63 to rotate, so that the rectangular frame 62 threaded to the lead screw 63 rises, thereby raising the collection box 22 to the top of the sedimentation tank 1, so that the staff can clean the first filter screen 24 in the collection box 22 to ensure the normal filtration function afterwards.

[0036] To ensure the stability of the collection box 22 during its ascent to the top of the sedimentation tank 1, the height of the bottom of the rectangular frame 62 gradually decreases from the protective frame 2 towards the ozone generator 3. A limit strip 8 is fixed to the bottom of the rectangular frame 62 near the ozone generator 3. A pad 81 is fixed to the side wall of the bottom of the rectangular frame 62 near the collection box 22. Multiple rotating rollers 82 are rotatably mounted on the top of the pad 81 to assist the movement of the collection box 22. The tops of the multiple rotating rollers 82 are flush with the bottom of the collection box 22. In this embodiment, multiple drainage holes 28 are provided through the bottom and side wall of the collection box 22.

[0037] The staff pulls the collection box 22 to the top of the pad 81. The rotating rod fixed to the top of the pad 81 reduces the friction on the surface of the collection box 22, allowing the collection box 22 to move easily into the rectangular frame 62. The bottom of the collection box 22 fits into the bottom of the rectangular frame 62, causing the collection box 22 to tilt towards the side closer to the ozone generator 3. The limiting strip 8 provides a good limiting effect for the collection box 22, making it less likely to slip. During the process of the collection box 22 being lifted to the top of the sedimentation tank 1 by the driving mechanism 6, multiple drainage holes 28 work together to provide good drainage, reducing the total weight of the collection box 22 and the water inside, and reducing the kinetic energy loss of the driving mechanism 6 during the process of lifting the collection box 22.

[0038] To reduce the impact of external factors on the transmission performance of the drive mechanism 6, a protective cover 73 is fixed to the top of the U-shaped mounting plate 61. The protective cover 73 covers the outside of the drive motor 64. Multiple heat dissipation holes 74 are provided through the side wall of the protective cover 73. A drain outlet 75 is provided at the intersection between the bottom of the protective cover 73 and the side wall of the protective cover 73. The protective cover 73 provides good protection for the drive motor 64, effectively blocking the direct damage of external factors such as dust and moisture to the drive motor 64, extending the service life of the drive motor 64. The multiple heat dissipation holes 74 ensure air circulation, which helps to dissipate the heat generated by the drive motor 64 during operation in a timely manner, avoiding the impact of overheating on the performance and transmission effect of the drive motor 64. The drain outlet 75 ensures that the water entering the protective cover 73 is quickly discharged, preventing water accumulation on the top of the U-shaped mounting plate 61 and damage to the drive motor 64. In this embodiment, an upper corrugated pipe 71 is fixed between the bottom of the horizontal section of the U-shaped mounting plate 61 and the top of the rectangular frame 62, and the upper corrugated pipe 71 covers the outside of the lead screw 63. A support plate 7 is rotatably mounted on the lower end of the lead screw 63, and the axis of the bearing in the support plate 7 coincides with the axis of the lead screw 63. A lower corrugated pipe 72 is fixed between the top of the support plate 7 and the inner top of the rectangular frame 62, and the lower corrugated pipe 72 covers the outside of the lead screw 63.

[0039] When the operator starts the drive motor 64 to move the rectangular frame 62 up and down, the upper corrugated pipe 71 and the lower corrugated pipe 72 adapt to the movement of the rectangular frame 62, so that the lead screw 63 is always wrapped by the upper corrugated pipe 71 and the lower corrugated pipe 72. This effectively blocks external factors such as dust and moisture from directly damaging the lead screw 63, prevents these factors from adversely affecting the transmission effect of the lead screw 63, reduces the probability of corrosion caused by the lead screw 63 being exposed, and ensures the stability of the lead screw 63 during the transmission process.

[0040] To further improve the filtration effect on wastewater, a pair of fixing plates 9 are fixed on the inner walls of both sides of the sedimentation tank 1, and a second filter screen 91 is set between the fixing plates 9. The second filter screen 91 is located between the inner walls of both sides of the sedimentation tank 1.

[0041] The second filter screen 91 further removes suspended solids and impurities from the wastewater, improving the water purification effect. The second filter screen 91 helps to evenly distribute the water flow, making the flow of wastewater in the sedimentation tank 1 more stable and improving the sedimentation efficiency. When the staff needs to clean the second filter screen 91 separately, they can directly lift the handle at the top of the second filter screen 91 manually to facilitate cleaning or replacement of the filter screen and maintain the effectiveness of the filtration system.

[0042] Example 2, as Figure 7As shown, the difference between this embodiment and Embodiment 1 is only that: an activated carbon storage mesh box 10 is fixed in the sedimentation tank 1 near the ozone generator 3. The activated carbon storage mesh box 10 is filled with activated carbon particles, and the particle size of the activated carbon particles is larger than the pore size of the mesh box 10. The activated carbon particles in the activated carbon storage mesh box 10, through their capillary structure and well-developed pore structure, can adsorb impurities such as suspended solids, organic matter, heavy metal ions, and dye molecules in the wastewater after secondary purification, significantly reducing the color and turbidity of the water and making the water clearer. In addition, activated carbon can adsorb odor substances and pigment molecules in the water, removing odors and color from the water and improving the water treatment effect.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
