Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, specifically to an industrial wastewater oxidation and filtration device. Background Technology

[0002] Industrial wastewater, including production wastewater and industrial sewage, refers to wastewater and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, by-products, and other pollutants generated during production that are lost with the water. Industrial wastewater is diverse and complex in composition. For example, wastewater from the electrolytic salt industry contains mercury; wastewater from the heavy metal smelting industry contains lead, cadmium, and other metals; wastewater from the electroplating industry contains cyanide and various heavy metals such as chromium; wastewater from the petroleum refining industry contains phenols; and wastewater from the pesticide manufacturing industry contains various pesticides. Because industrial wastewater often contains various toxic substances, it pollutes the environment and poses a significant threat to human health. Therefore, it must be treated to meet standards before being discharged. Industrial wastewater can be treated using activated carbon adsorption and filtration. Activated carbon has numerous micropores and a huge specific surface area, giving it a strong physical adsorption capacity, effectively adsorbing organic pollutants in wastewater. Furthermore, during the activation process, oxygen-containing functional groups are formed on the non-crystalline sites of the activated carbon surface. These groups give activated carbon chemical adsorption and catalytic oxidation and reduction properties, effectively removing some metal ions from wastewater.

[0003] However, existing industrial wastewater oxidation filtration equipment faces several pressing issues in practical use. Firstly, when activated carbon becomes saturated and needs replacement, traditional methods are complex, often requiring manual entry into the equipment for cleaning and replacement. This is not only labor-intensive and inefficient, but also poses a significant health risk to operators due to the potential presence of harmful gases and residual wastewater inside the equipment. Secondly, while some equipment offers a degree of automated activated carbon replacement, its complex structure and high cost, coupled with the risk of residual activated carbon or incomplete replacement, negatively impact subsequent filtration efficiency and the equipment's normal operation.

[0004] Therefore, developing an industrial wastewater oxidation filtration device that allows for convenient, efficient, and thorough replacement of activated carbon is of significant practical importance. Utility Model Content

[0005] To address the aforementioned issues, this application provides an industrial wastewater oxidation filtration device.

[0006] To achieve the above objectives, this application provides the following technical solution: an industrial wastewater oxidation filtration device, comprising a filter tank, a support grid horizontally disposed within the filter tank, activated carbon placed on the support grid, and a discharge mechanism disposed on the filter tank to discharge the activated carbon from the filter tank. The discharge mechanism includes a discharge component disposed on the top side of the filter tank, a lifting component disposed within the filter tank and controlling the lifting and lowering movement of the support grid, and a discharge curved plate disposed within the filter tank via a rotating component. When discharging the activated carbon, the lifting component controls the support grid and the activated carbon located on the support grid to move upward to the position of the discharge component, the bottom side of the discharge curved plate abuts against the top of the support grid, and the rotating component drives the discharge curved plate to rotate axially along the filter tank, thereby pushing the activated carbon out of the filter tank from the discharge component.

[0007] Preferably, the discharge assembly includes a discharge ring fixedly sleeved on the top side of the filter tank via an inner ring, a collection ring sleeved on the filter tank via an inner ring and located below the discharge ring, and a sealing element disposed on the filter tank and controlling the sealing of the discharge port opening. The inner and outer rings of the discharge ring are provided with discharge ports that pass through the filter tank; the top of the collection ring is provided with a collection groove located below the discharge port opening.

[0008] Preferably, the lifting assembly includes a lifting screw arranged axially along the filter tank and passing through the load-bearing grid, a lifting column threaded onto the lifting screw, a second slide rod arranged parallel to the lifting screw and slidingly passing through the lifting column, and a first drive component for controlling the rotation of the lifting screw, wherein the second slide rod is fixedly disposed inside the filter tank.

[0009] Preferably, the rotating assembly includes a transmission pipe that moves axially through the top of the filter tank, a cleaning gear ring fixedly sleeved on the top of the transmission pipe, and a drive gear disposed on the filter tank and driven by a motor, the drive gear meshing with the cleaning gear ring; a discharge curved plate is fixedly connected to the bottom end of the transmission pipe.

[0010] Preferably, the discharge assembly further includes a sealing ring that is movably fitted onto the discharge port opening via an inner ring, and a control component disposed on the filter tank and controlling the vertical movement of the sealing ring.

[0011] Preferably, the control component includes a lifting ring rotatably disposed above the filter tank, two protrusions symmetrically disposed on the lifting ring about the center, two rotating rods fitted to the top end face of the lifting ring, two lifting bars rotatably disposed on the two rotating rods at opposite ends, a limiting structure disposed on the filter tank to restrict the movement of the lifting bars in the vertical direction, and a second driving component to drive the lifting bars to rotate around the axial direction; the lifting bars are connected to the top of the sealing ring.

[0012] Preferably, the limiting structure includes a first slide rod that is vertically disposed on the filter tank and movably passes through the lifting bar, and a limiting spring that is slidably sleeved on the first slide rod and whose two ends are respectively connected to the end of the first slide rod and the lifting bar. When the limiting spring is in the normal extended state, the rotating rod is in contact with the end face of the lifting ring.

[0013] The beneficial effects of this utility model are:

[0014] 1. This equipment features a discharge mechanism, including a discharge assembly, a lifting assembly, and a discharge curved plate. When activated carbon needs to be discharged, the lifting assembly controls the upward movement of the carrying grid and activated carbon to the discharge assembly position. The discharge curved plate, driven by the rotating assembly, rotates along the axial direction of the filter tank, pushing the activated carbon out of the filter tank. This design achieves automated discharge of activated carbon, eliminating the need for manual entry into the equipment for cleaning and replacement, significantly reducing labor intensity, improving work efficiency, and avoiding potential safety risks associated with manual operation.

[0015] 2. The bottom side of the discharge curved plate is attached to the top of the load-bearing grid. During rotation, it can fully and effectively push the activated carbon out of the discharge port, reducing the residue of activated carbon in the equipment, ensuring the thoroughness of activated carbon replacement, and helping to ensure the normal operation and filtration effect of subsequent filtration equipment.

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the embodiments without creative effort are all within the protection scope of this utility model.

[0023] Example 1: Reference Figures 1-4 An industrial wastewater oxidation filtration device is shown, comprising a filter tank 1, a support grid 20 horizontally disposed within the filter tank 1, activated carbon placed on the support grid 20, and a discharge mechanism disposed on the filter tank 1 to discharge the activated carbon from the filter tank 1. The discharge mechanism includes a discharge component disposed on the top side of the filter tank 1, a lifting component disposed within the filter tank 1 and controlling the lifting and lowering movement of the support grid 20, and a discharge curved plate 24 disposed inside the filter tank 1 via a rotating component. When discharging the activated carbon, the lifting component controls the support grid 20 and the activated carbon located on the support grid 20 to move upward to the position of the discharge component. The bottom side of the discharge curved plate 24 is attached to the top of the support grid 20. The rotating component drives the discharge curved plate 24 to rotate axially along the filter tank 1, and the discharge curved plate 24 pushes the activated carbon out of the filter tank 1 from the discharge component.

[0024] like Figures 1-4As shown, in this embodiment, industrial wastewater enters the filter tank 1 and flows through the activated carbon layer laid on the support grid 20. The activated carbon removes pollutants such as heavy metals and organic matter from the wastewater through physical adsorption (microporous structure) and chemical adsorption (surface functional groups). The filtered water is discharged from the bottom or side of the filter tank, meeting discharge or reuse standards. When the activated carbon becomes saturated (e.g., the concentration of pollutants in the effluent exceeds the standard or the preset operating time is reached), the discharge procedure is initiated. The lifting component drives the support grid 20 upward, raising the saturated activated carbon layer to the location of the discharge component (top side of the filter tank 1). This process is completely enclosed, preventing operators from coming into contact with toxic wastewater and residual pollutants. The rotating component drives the discharge curved plate 24 to rotate along the axial direction of the filter tank 1. The curved surface or inclined structure of the plate continuously pushes the activated carbon towards the discharge component. Under the mechanical thrust of the discharge curved plate 24, the activated carbon is completely discharged from the filter tank through the discharge component. After the material discharge is completed, the lifting assembly resets the bearing grid 20 to its initial position, and fresh activated carbon can be automatically or manually replenished through the top feeding port to prepare for the next round of filtration.

[0025] In this embodiment, no manual entry into the tank is required, avoiding contact with hazardous substances and ensuring the personal safety of personnel. This embodiment only requires two sets of power mechanisms: lifting and rotating. Compared to traditional conveyor belts or pneumatic systems, the structure is simpler and maintenance costs are lower. The tight fit design between the discharge curved plate 24 and the load-bearing grid 20 reduces power loss and improves energy utilization.

[0026] like Figure 1 and Figure 2 As shown, the discharge assembly includes a discharge ring 18 fixedly sleeved on the top side of the filter tank 1 via an inner ring, a collection ring 2 sleeved on the filter tank 1 via an inner ring and located below the discharge ring 18, and a sealing element disposed on the filter tank 1 and controlling the opening of the discharge port 19 to seal. The inner and outer rings of the discharge ring 18 are provided with discharge ports 19 that pass through the filter tank 1; the top of the collection ring 2 is provided with a collection groove 3 located below the opening of the discharge port 19.

[0027] In this embodiment, when the activated carbon becomes saturated and needs to be discharged and replaced, the control seal opens. The seal can be controlled to open the discharge port 19 by mechanical, electric, or pneumatic means. After the seal opens the discharge port 19, other components in the discharge mechanism (the lifting assembly lifts the carrying grid 20 and activated carbon to the discharge position, and the discharge curved plate 24 rotates to push the activated carbon) work together to push the activated carbon out of the discharge port 19 from the filter tank 1. The discharged activated carbon falls into the collection groove 3 at the top of the collection ring 2 under gravity. The shape and size of the collection groove 3 are reasonably designed to effectively receive and accommodate the discharged activated carbon and prevent it from scattering. After all the activated carbon has been discharged, the control seal closes the discharge port 19 again. Similarly, the corresponding drive mechanism makes the seal re-fit tightly against the opening of the discharge port 19, restoring the filter tank 1 to a sealed state, so that new activated carbon can be added and wastewater filtration can continue.

[0028] In this embodiment, the discharge ports 19 on the inner and outer rings of the discharge ring 18 are the key channels for the activated carbon to be discharged from the filter tank 1. By rationally designing the position, shape, and size of the discharge ports 19, it can be ensured that the activated carbon can be discharged smoothly and quickly from the filter tank, improving the discharge efficiency. The discharge ring 18 is fixedly sleeved on the top side of the filter tank 1 through the inner ring, serving a positioning and support function. It provides an installation base for other related components (such as seals), ensuring the relative positional accuracy and stability between the components of the discharge assembly. The collection ring 2 is located below the discharge ring 18, and the collection groove 3 on its top can accurately receive the activated carbon discharged from the discharge port 19. This avoids the activated carbon from scattering around the filter tank, causing environmental pollution and resource waste, and also facilitates the subsequent centralized treatment and recycling of the discharged activated carbon. The collection groove 3 can prevent the activated carbon from splashing onto the equipment, ground, or other components around the filter tank during the discharge process, thus protecting the surrounding environment. In addition, the design of the collection ring 2 and the collection groove 3 can also reduce the contact between the activated carbon and the external environment, reducing the risk of secondary pollution from the activated carbon.

[0029] In this embodiment, during the normal filtration stage, the seal tightly seals the discharge port 19, preventing wastewater from leaking out of the filter tank 1. This ensures that the wastewater is treated according to the predetermined filtration path, maintaining the normal operation of the filtration system and avoiding problems such as decreased treatment efficiency and environmental pollution caused by wastewater leakage. The seal can be opened and closed to precisely control the timing of activated carbon discharge. The seal is only opened when activated carbon needs to be discharged, and closed immediately after discharge, ensuring that the filter tank 1 is always in a suitable sealed state to meet the wastewater treatment needs under different operating conditions.

[0030] like Figure 3 and Figure 4As shown, the lifting assembly includes a lifting screw 22 that is axially arranged along the filter tank 1 and passes through the load-bearing grid 20, a lifting column 21 that is threadedly connected to the lifting screw 22, a slide rod 23 that is parallel to the lifting screw 22 and slides through the lifting column 21, and a first driving member that controls the rotation of the lifting screw 22. The slide rod 23 is fixedly arranged inside the filter tank 1.

[0031] In this embodiment, when the activated carbon becomes saturated and needs to be replaced, the lifting assembly starts working. The first driving component drives the lifting screw 22 to rotate along the axial direction of the filter tank 1. Since the lifting screw 22 and the lifting column 21 are connected by a thread, when the lifting screw 22 rotates, it generates an axial force. The slide bar 23 is fixedly installed inside the filter tank 1 and slides through the lifting column 21, which restricts the lifting column 21 to only move linearly along the direction of the slide bar 23 and cannot rotate with the lifting screw 22. Therefore, under the action of the axial force generated by the rotation of the lifting screw 22, the lifting column 21 will move up or down along the slide bar 23. The carrying grid 20 is connected to the lifting column 21, and the movement of the lifting column 21 will drive the carrying grid 20 to move together. When the lifting column 21 moves upward, the carrying grid 20 and the activated carbon placed on it will also move upward until they reach the position of the discharge assembly, preparing for the subsequent discharge of activated carbon. After the discharge is completed, the first driving component reverses its rotation, causing the carrying grid 20 and the new activated carbon to descend back to the normal filtration position in the reverse process described above.

[0032] In this embodiment, when activated carbon needs to be discharged, the lifting assembly can precisely lift the supporting grid 20 and the activated carbon to the position of the discharge assembly. By controlling the operating time and speed of the first driving component, the number of rotations of the lifting screw 22 can be accurately controlled, thereby precisely controlling the rising height of the lifting column 21 and the supporting grid 20, ensuring that the activated carbon can smoothly reach the discharge position and cooperate with components such as the discharge curved plate to complete the discharge operation. After discharge, the lifting assembly can lower the supporting grid 20 and the new activated carbon back to the appropriate filtration position, ensuring the contact area and filtration effect between the activated carbon layer and the wastewater, allowing the equipment to resume normal filtration operation. This precise position adjustment function is crucial for ensuring the normal operation and filtration effect of the equipment. During the normal filtration stage, the lifting assembly provides stable support for the supporting grid 20. The structural design of the lifting column 21 and the slide bar 23 allows the supporting grid 20 to remain horizontal, ensuring uniform distribution of activated carbon and avoiding uneven accumulation of activated carbon due to tilting of the supporting grid, which would affect the filtration effect.

[0033] In this embodiment, the first driving component includes a driving rod 15 that extends axially through the filter tank 1. The bottom end of the driving rod 15 is connected to a lifting screw 22, and the driving rod 15 is driven by a lifting motor 14 disposed on the filter tank 1.

[0034] like Figure 1 and Figure 4 As shown, the rotating assembly includes a transmission pipe 11 that moves axially through the top of the filter tank 1, a cleaning gear ring 12 that is fixedly sleeved on the top of the transmission pipe 11, and a drive gear 13 that is disposed on the filter tank 1 and driven by a motor. The drive gear 13 meshes with the cleaning gear ring 12. The bottom end of the transmission pipe 11 is fixedly connected to a discharge curved plate 24.

[0035] In this embodiment, the motor drives the drive gear 13 to rotate. Since the drive gear 13 meshes with the cleaning gear ring 12 fixedly sleeved at the top of the transmission tube 11, the rotation of the drive gear 13 will cause the cleaning gear ring 12 to rotate as well. The cleaning gear ring 12 is fixedly connected to the transmission tube 11, so the transmission tube 11 will rotate around its own axis as the cleaning gear ring 12 rotates. The rotation of the transmission tube 11 will cause the discharge curved plate 24 to rotate along the axis of the filter tank 1. During rotation, the bottom side of the discharge curved plate 24 will contact the activated carbon on the carrying grid 20 and push the activated carbon towards the discharge port, ultimately discharging the activated carbon from the discharge port into the filter tank. When all the activated carbon is discharged, the control system issues a stop command, the motor stops running, and the drive gear 13, cleaning gear ring 12, transmission tube 11, and discharge curved plate 24 all stop rotating. The rotating components return to their initial stationary state, awaiting the next discharge operation.

[0036] In this embodiment, the rotating assembly transmits the rotational power of the motor to the transmission tube 11 through a combination of a motor, a drive gear 13, and a cleaning gear ring 12, thereby driving the discharge curved plate 24 to rotate. This power transmission method has a simple structure and high transmission efficiency, and can reliably realize the rotation of the discharge curved plate to meet the needs of activated carbon discharge. By controlling the motor speed and running time, the rotation speed and rotation angle of the discharge curved plate 24 can be precisely controlled. The drive gear 13 and the cleaning gear ring 12 adopt a gear meshing transmission method, which has the advantages of accurate transmission ratio, smooth operation, and high reliability. During the discharge process, the rotation of the transmission tube 11 and the discharge curved plate 24 can be guaranteed to be stable, without slippage or jamming, ensuring that the activated carbon can be discharged smoothly. Components such as the transmission tube 11 and the discharge curved plate 24 are usually made of high-strength materials, which can withstand the reaction force of the activated carbon on the discharge curved plate during the discharge process and the torque during the transmission process, ensuring that the rotating assembly will not deform or be damaged during long-term use, thereby improving the service life of the equipment and the reliability of discharge.

[0037] The discharge assembly also includes a sealing ring 4 that is movably fitted onto the opening of the discharge port 19 via an inner ring, and a control component that is disposed on the filter tank 1 and controls the sealing ring 4 to move in the vertical direction.

[0038] The control components include a lifting ring 8 rotatably mounted above the filter tank 1, two protrusions 9 symmetrically arranged on the lifting ring 8 about the center, two rotating rods fitted to the top end face of the lifting ring 8, two lifting bars 5 rotatably mounted on the two rotating rods at opposite ends, a limiting structure on the filter tank 1 to restrict the movement of the lifting bars 5 in the vertical direction, and a second driving component to drive the lifting ring 8 to rotate around the axial direction; the lifting bars 5 are connected to the top of the sealing ring 4.

[0039] In this embodiment, when the activated carbon becomes saturated and needs to be replaced, the second driving component starts operating. The second driving component drives the lifting ring 8 to rotate around its axial direction. As the lifting ring 8 rotates, two protrusions 9, which are symmetrically arranged about the center on the lifting ring 8, will sequentially contact the rotating rod attached to the top end face of the lifting ring 8. When the protrusion 9 rotates to contact the rotating rod, it will apply an upward thrust to the rotating rod. Under the thrust of the protrusion 9, the rotating rod rotates upward around its connection point with the filter tank 1, thereby driving the lifting strips 5, which are respectively rotated and arranged at opposite ends of the two rotating rods, to move upward. Since the lifting strips 5 are restricted by the limiting structure, they can only move in the vertical direction, so the lifting strips 5 will move upward smoothly along the limiting structure. The lifting strips 5 are connected to the top of the sealing ring 4. As the lifting strips 5 rise, the sealing ring 4 will also be lifted upward, gradually separating from the opening of the discharge port 19, thereby opening the discharge port. At this time, other components in the discharge assembly (such as the discharge curved plate 24, etc.) can work together to discharge the activated carbon from the discharge port into the filter tank 1. Once all the activated carbon has been discharged, the second drive unit reverses its rotation, causing the lifting ring 8 to rotate in the opposite direction. The protrusion 9 no longer exerts an upward thrust on the rotating rod, and the sealing ring 4, under its own weight, moves downward with the lifting bar 5, re-fitting tightly against the opening of the discharge port 19, sealing the discharge port, and the equipment returns to normal filtration status.

[0040] In this embodiment, the sealing ring 4 is movably fitted onto the opening of the discharge port 19 via an inner ring, ensuring a tight fit and reliable seal. During normal filtration, it prevents wastewater leakage from the filter tank, avoiding environmental pollution, while maintaining stable pressure within the filter tank and improving filtration efficiency. The sealing ring 4 is installed in a movable manner, and its vertical movement can be easily controlled via a control component, enabling the opening and closing of the discharge port. This design allows for more flexible discharge operations, enabling timely discharge of saturated activated carbon as needed. The control component is driven by a second drive component, automating the opening and closing of the sealing ring. Compared to manual operation, automated control is faster and more accurate, reducing errors and time costs associated with manual operation, and improving overall equipment operating efficiency and discharge reliability.

[0041] In this embodiment, the second driving component includes a lifting gear ring disposed on the outer ring surface of the lifting ring 8, a motor disposed on the filter tank 1, and a driving gear 10 disposed on the output end of the motor. The driving gear 10 meshes with the lifting gear ring, so that the lifting ring 8 can be driven to rotate through the meshing of the driving gear 10 with the lifting gear ring.

[0042] like Figure 1 and Figure 2 As shown, the limiting structure includes a slide rod 6 that is vertically mounted on the filter tank 1 and moves through the lifting bar 5, and a limiting spring 7 that is slidably sleeved on the slide rod 6 and connected at both ends to the end of the slide rod 6 and the lifting bar 5 respectively. When the limiting spring 7 is in the normal extended state, the rotating rod is attached to the end face of the lifting ring 8.

[0043] In this embodiment, when activated carbon needs to be discharged, the second driving component is activated, causing the lifting ring 8 to rotate axially. As the lifting ring 8 rotates, the protrusion 9 on it begins to contact the rotating rod. The protrusion 9 applies an upward thrust to the rotating rod, causing the rotating rod to rotate upward around its connection point with the filter tank 1, thereby driving the lifting bar 5 to move upward along the slide rod 6. During the upward movement of the lifting bar 5, the limiting spring 7 is stretched, and its elastic force gradually increases, but it still ensures that the lifting bar 5 rises smoothly along the slide rod 6 without shaking or jamming. The slide rod 6 is set vertically and moves through the lifting bar 5, providing precise guidance for the movement of the lifting bar 5. During the opening and closing of the discharge port by the sealing ring, the lifting bar 5 needs to move along a specific path. The presence of the slide rod 6 ensures that the lifting bar 5 can only move in a straight line in the vertical direction, avoiding the lifting bar 5 from deviating due to forces in other directions. This ensures that the sealing ring 4 can accurately seal and separate from the discharge port 19, improving the reliability of the discharge operation.

[0044] In this embodiment, during the movement of the lifting bar 5, it may be affected by various external forces, such as equipment vibration and fluid impact. The slide bar 6 can limit the sway range of the lifting bar 5, keeping it stable during movement and reducing problems such as poor sealing or difficulty in opening between the sealing ring and the discharge port caused by swaying. When the protrusion 9 pushes the rotating rod to raise the lifting bar 5, the limiting spring 7 is stretched. In this process, the limiting spring 7 can play a buffering role, absorbing part of the impact force of the protrusion 9 on the rotating rod, avoiding damage to components such as the rotating rod and the lifting bar 5 due to excessive impact force. At the same time, the buffering effect can also make the rising process of the lifting bar 5 more stable, reduce the impact on the sealing ring 4, and extend the service life of the sealing ring.

[0045] like Figure 1 As shown, the top and bottom of the filter tank 1 are respectively provided with a feed pipe 16 and a discharge pipe 17, and both the feed pipe 16 and the discharge pipe 17 are equipped with valves.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
