Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a water treatment device based on biochar-supported nano-zero-valent iron. Background Technology

[0002] In the treatment of industrial wastewater or the purification of drinking water, water treatment devices based on biochar-supported nano-zero valent iron are generally used. Biochar-supported nano-zero valent iron has a high specific surface area and good adsorption performance, which can efficiently remove heavy metals and other pollutants from water, and it is not easy to generate secondary pollution during use.

[0003] In existing technologies, biochar-supported nano-zero valent iron is generally used as part of the filter medium and installed inside the filter box. When water flows through the filter box, the biochar-supported nano-zero valent iron can adsorb and remove pollutants in the water.

[0004] However, after prolonged use, when the biochar-supported nano-zero-valent iron becomes saturated and can no longer effectively remove pollutants from the water, the filter box containing the biochar-supported nano-zero-valent iron needs to be replaced. This requires using tools such as screwdrivers to remove the bolts from the filter box inside the container. When the filter box is located in a confined space, the use of screwdrivers is inconvenient due to the limited space layout, making the replacement of the filter box with the biochar-supported nano-zero-valent iron difficult and inefficient. This, in turn, affects the overall efficiency of the water treatment device. Utility Model Content

[0005] The purpose of this invention is to provide a water treatment device based on biochar-supported nano-zero-valent iron to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A water treatment device based on biochar-supported nano-zero-valent iron, comprising a placement tank and a lid. A filter box is slidably connected inside the placement tank. A lid is installed on the top of the filter box. Multiple connecting blocks (two) are fixedly connected to the outside of the filter box. Multiple connecting blocks (one) are fixedly connected to the outside of the lid. Connecting blocks (two) are slidably connected to the bottom of connecting blocks (one). A rod is inserted into the inside of connecting blocks (two). The upper side of the rod passes through connecting blocks (one) and is fixedly connected to the bottom of the lid. Multiple slots are formed inside the placement tank. A locking block is engaged inside each slot. A limiting groove is formed on the outside of each locking block. A limiting ring is fixedly connected to the inner wall of each slot. Multiple limiting blocks are fixedly connected to the inner side of the limiting ring. Two mounting slots are formed inside each connecting block (two). An elastic element is sleeved on the outside of each locking block. An mounting piece is fixedly connected to the end of the locking block away from the slot. A push rod is fixedly connected to the other end of the mounting piece.

[0007] Preferably, the inside of the placement bucket is provided with multiple connecting slots, the first connecting block is slidably connected to the inside of the connecting slot, the second connecting block is slidably connected to the inside of the connecting slot, and the lower side of the insertion rod is inserted into the inside of the connecting slot.

[0008] Preferably, the inner side of the limiting ring is in contact with the outer side of the locking block, and the limiting block is in contact with the inner side of the limiting groove.

[0009] Preferably, the card block is slidably connected to the inside of the mounting groove through the connecting block, and the mounting piece is slidably connected to the inside of the mounting groove.

[0010] Preferably, one end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention proposes a water treatment device based on biochar-loaded nano-zero ferric iron.

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a water treatment device based on biochar-supported nano-zero valent iron, comprising a placement tank 1 and a lid 2. The top of the placement tank 1 is fitted with the bottom of the lid 2. A water inlet pipe is installed on the upper side of the lid 2, and a drain pipe is installed on the lower side of the placement tank 1. A filter box 3 is slidably connected inside the placement tank 1. A lid 4 is installed on the top of the filter box 3. The filter box 3 contains biochar-supported nano-zero valent iron, which is contained inside the filter box 3 by the lid 4. Multiple connecting blocks 6 are fixedly connected to the outside of the filter box 3, and multiple connecting blocks 5 are fixedly connected to the outside of the lid 4. The connecting blocks 6 are slidably connected to the bottom of the connecting blocks 5, and the connecting blocks 5 and 6 mutually limit each other, so that the filter box 3 and the lid 4 are installed inside the lid 2. The connecting block 2 6 has a rod 8 inserted inside. The upper side of the rod 8 passes through the connecting block 1 5 and is fixedly connected to the bottom of the lid 2. By fitting the lid 2 with the placement bucket 1, the connecting block 1 5 and the connecting block 2 6 can be limited, thereby limiting the filter box 3 and the lid 4. The placement bucket 1 has multiple connecting grooves 7 inside. The connecting block 1 5 is slidably connected inside the connecting groove 7. The connecting groove 7 limits the connecting block 1 5 so that it will not deviate when sliding. The connecting block 2 6 is slidably connected inside the connecting groove 7. The connecting groove 7 limits the connecting block 2 6 so that it can slide smoothly. The lower side of the rod 8 is inserted inside the connecting groove 7 so that the rod 8 can stably limit the connecting block 1 5 and the connecting block 2 6.

[0022] When it is necessary to replace the biochar-loaded nano-zero-valent iron inside the filter box 3 and the lid 4, pull the lid 2 upwards to detach it from the container 1. This allows the insert rod 8 to disengage from the connecting blocks 5 and 6, freeing them from the constraint of the insert rod 8. Pulling the filter box 3 upwards then causes the lid 4, connecting blocks 5 and 6 to detach from the container 1, freeing the filter box 3 from the lid 4. Pulling the lid 4 upwards further separates it from the filter box 3, exposing the biochar-loaded nano-zero-valent iron inside the filter box 3. After replacing the biochar-loaded nano-zero ferric iron, the filter box 3 is covered with the lid 4, and the connecting block 5 and the connecting block 6 are aligned. The filter box 3 is then slid into the inside of the lid 2, allowing the connecting block 6 and the connecting block 5 on the lid 4 to slide into the connecting groove 7. The lid 2 is then fitted to the top of the container 1, allowing the insert rod 8 to pass through the connecting block 5 and the connecting block 6 and be inserted into the connecting groove 7. This allows the filter box 3 containing biochar-loaded nano-zero ferric iron to be conveniently installed inside the lid 2, resulting in a high replacement efficiency for the filter box 3 containing biochar-loaded nano-zero ferric iron, thus not affecting the efficiency of the water treatment device.

[0023] Example 2: Based on Example 1, in order to achieve stable installation of connecting block 5 and connecting block 6 inside the connecting groove 7, multiple slots 17 are provided inside the placement barrel 1. A locking block 11 is engaged inside the slot 17, so that the locking block 11 can be limited. A limiting groove 12 is provided on the outside of the locking block 11. A limiting ring 9 is fixedly connected to the inner wall of the slot 17. The inner side of the limiting ring 9 is in contact with the outside of the locking block 11, so that the friction between the locking block 11 and the slot 17 increases. Multiple limiting blocks 10 are fixedly connected to the inner side of the limiting ring 9. The limiting blocks 10 are in contact with the inside of the limiting groove 12, so that the friction between the limiting ring 9 and the locking block 11 increases, thereby making the locking of the locking block 11 and the slot 17 more stable.

[0024] When connecting block 5 and connecting block 6 are slidably installed inside the connecting groove 7, by moving the two locking blocks 11 to the opposite side, the locking blocks 11 can slide into the groove 17. At this time, the limiting ring 9 and the limiting block 10 can slide outside the locking block 11 and be deformed by the locking block 11. Then, when the locking block 11 is engaged with the groove 17, the limiting ring 9 and the limiting block 10 can perform a reset movement, so that the limiting ring 9 can fit tightly with the locking block 11 and the limiting block 10 can fit tightly with the inside of the limiting groove 12, thereby making the locking of the locking block 11 and the groove 17 more stable.

[0025] Example 3: Based on Example 2, in order to facilitate the engagement of the push block 11 with the slot 17, two mounting slots 13 are provided inside the connecting block 2 6. An elastic element 14 is sleeved on the outside of the push block 11. The push block 11 passes through the connecting block 1 5 and is slidably connected inside the mounting slot 13, so that the connecting block 2 6 and the connecting block 1 5 can be limited. The end of the push block 11 away from the slot 17 is fixedly connected to the mounting piece 15. The mounting piece 15 is slidably connected inside the mounting slot 13. The mounting slot 13 limits the mounting piece 15, so that the mounting piece 15 can slide smoothly. One end of the elastic element 14 is fixedly connected to the inner wall of the mounting slot 13, and the other end of the elastic element 14 is fixedly connected to the mounting piece 15. The other end of the mounting piece 15 is fixedly connected to the push rod 16. The side of the push rod 16 away from the mounting piece 15 is arc-shaped and is slidably connected to the outside of the insertion rod 8, so that the insertion rod 8 can push the mounting piece 15 to move outward.

[0026] When the insert rod 8 is inserted into the connecting groove 7, the insert rod 8 slides along the arc of the push rod 16, thereby causing the two push rods 16 to move to opposite sides. This allows the push rods 16 to push the mounting piece 15 towards the slot 17, causing the mounting piece 15 to deform while pressing the elastic element 14, and thus push the locking block 11 to engage with the slot 17. Conversely, when the insert rod 8 disengages from the interior of the connecting block 1 5 and the connecting block 2 6, the insert rod 8 no longer presses the push rod 16, allowing the elastic element 14 to reset. This allows the elastic element 14 to push the mounting piece 15 inward, causing the mounting piece 15 to move the locking block 11 inward, thus allowing the locking block 11 to disengage from the interior of the slot 17.

[0027] In actual use, by pulling the lid 2 upwards, the lid 2 is disengaged from the container 1, allowing the insert rod 8 to disengage from the inside of connecting block 5 and connecting block 6. This removes the constraint of the insert rod 8 from connecting block 5, connecting block 6, and push rod 16, allowing the elastic element 14 to reset. The elastic element 14 then pushes the mounting plate 15 inwards, causing the mounting plate 15 to move the locking block 11 inwards. This allows the locking block 11 to slide against the limiting ring 9 and limiting block 10, ultimately separating the locking block 11 from the limiting ring 9 and limiting block 10. 11 can disengage from the inside of the slot 17, and then pull the filter box 3 upward, so that the filter box 3 can move the cover 4, connecting block 1 5 and connecting block 2 6 out of the inside of the placement bucket 1, so that the filter box 3 and the cover 4 are no longer restricted. Then, pull the cover 4 upward, so that the cover 4 and the filter box 3 are separated, and the biochar-loaded nano-zero ferric iron inside the filter box 3 is exposed to the outside, so that the biochar-loaded nano-zero ferric iron can be replaced. After replacement, by covering the filter box 3 with the cover 4 and aligning the connecting block 1 5 and the connecting block 2 6, the filter box 3 is slid into the inside of the bucket cover 2. This allows connecting block 2 6 and connecting block 1 5 on the lid 4 to slide into the connecting groove 7, thus fitting the lid 2 against the top of the container 1. This allows the insert rod 8 to pass through connecting block 1 5 and connecting block 2 6 and be inserted into the connecting groove 7. The insert rod 8 also slides along the arc of the push rod 16, causing the two push rods 16 to move away from each other. This push rods 16 push the mounting piece 15 towards the slot 17, causing the mounting piece 15 to deform under the pressure of the elastic element 14. Simultaneously, the slot 11 slides into the slot 17. At this point, the limiting ring 9 and the limiting block 10... The filter slides outside the locking block 11 and is deformed by the locking block 11. When the locking block 11 engages with the locking groove 17, the limiting ring 9 and the limiting block 10 can perform a reset movement, so that the limiting ring 9 can fit tightly with the locking block 11 and the limiting block 10 can fit tightly with the inside of the limiting groove 12. This makes the locking of the locking block 11 and the locking groove 17 more stable, so that the filter box 3 loaded with biochar-loaded nano-zero ferric iron can be conveniently installed inside the tank cover 2. This makes the replacement efficiency of the filter box 3 loaded with biochar-loaded nano-zero ferric iron higher, and thus does not affect the efficiency of the water treatment device.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
