[0027] This utility model will be clearly and completely described with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on this utility model are within the protection scope of this utility model.

[0028] Example 1

[0029] This utility model provides a water treatment adsorption device, including a water collection tank 6, such as... Figures 1-6The upper and lower sections each have an open end and a closed end. The closed end of the upper section has a water inlet 1 for water intake. The open end of the upper section is detachably connected to the open end of the lower section via a thread 5. It is understood that after connection, the upper and lower sections form a sealed fit. The threaded connection and sealing can be achieved by setting a sealing ring on the mating end faces, which is existing technology and will not be elaborated here. The closed end of the lower section has a water outlet 2 for water outlet. Inside the upper section, near the closed end, a water collection tray 10 is also provided. The water collection tray 10 is fixedly connected to the inner side of the upper section. The water collection tray 10 has multiple openings, each facing the lower section. A baffle 12 capable of opening and closing an opening is provided on one side; a drive motor 13 is also included, the drive end of which is connected to the baffle 12, enabling the baffle 12 to open or close; a pressure sensor 14 is provided on the side of the water collection tray 10 facing the upper opening end, the detection end of the pressure sensor 14 is sealed through the water collection tray 10 to the upper space of the water collection tray 10, used to measure the water pressure above the water collection tray 10 (in practice, the pressure sensor 14 can also be entirely located on the side of the water collection tray 10 facing the upper sealed end); the pressure sensor 14 is signal-connected to a controller (not shown in the figure), and the controller controls the drive motor 13. In use, the pressure sensor 14 transmits the collected data to the controller, and the controller controls the drive motor 13 to open and close the baffle 12 on the water collection tray 10 according to the set water pressure value. When the pressure sensor 14 detects that the water pressure above the water collection tray 10 reaches the set value, the controller controls all or a certain number of openings on the water collection tray 10 to open; when the water pressure above the water collection tray 10 drops to the set value, the controller controls the openings on the water collection tray 10 to close again. This design prevents water from accumulating on the upper part of the filter component 7 and squeezing the adsorbent, thus affecting the filtration effect. At the same time, the water collection tray 10 can slow down the water flow rate and make the water receiving area uniform, improving the filtration effect of the adsorbent. The adsorption effect of the equipment is improved from the structural design. A filter component 7 is also provided in the lower closed end. The filter component 7 is detachably connected to the inner side of the lower closed end. The filter component 7 includes filter paper 9, adsorbent, and pressure ring 8. The pressure ring 8, adsorbent, and filter paper 9 are arranged sequentially from top to bottom on the inner side of the lower closed end, and the adsorbent and filter paper 9 are fixed above the outlet 2 of the lower closed end by the pressure ring 8. After the adsorbent has been used for a period of time, the filter paper 9 and adsorbent can be replaced by removing the pressure ring 8.

[0030] In specific implementations, the opening can be square, circular, etc. In this embodiment, Figure 4The openings shown are hexagonal, and multiple openings are distributed in a honeycomb pattern on the water collection plate 10. The hexagonal openings can slow down the water flow, which is more effective than circular openings. An exhaust pipe 4 is also provided on the upper closed end. One end of the exhaust pipe 4 is connected to the inside of the water collection tank 6, and the other end is equipped with a nut 3 threaded to it. Unscrewing the nut 3 allows for venting, preventing air blockage and improving water treatment efficiency. The adsorbent is bamboo-based biochar, which is obtained by calcining bamboo raw materials. The bamboo raw materials are moso bamboo or moso bamboo waste. The bamboo raw materials are washed, dried, crushed, and sieved to obtain bamboo particles. The bamboo particles are placed in a tubular furnace for pyrolysis, while an inert gas is introduced to ensure an oxygen-free environment. The tubular furnace is heated to 400-800℃ at a heating rate of 5-20℃ / min and maintained at a constant temperature for 2-3 hours to obtain the bamboo-based biochar. Using this material as an adsorbent can remove impurities from water and significantly reduce COD content. It is packaged in a water-permeable fabric, and its shape, the shape of the pressure ring 8, the shape of the filter paper 9, and the inner side of the lower closed end correspond. The pressure ring 8 uses its own weight to press down the edge of the adsorbent packaging and the filter paper 9. (See [reference needed]). Figure 5 The adsorbent and filter paper 9 are fixed above the outlet 2 at the closed end of the lower section. If necessary, a fastening mechanism can also be provided between the pressure ring 8 and the inner wall of the lower section to improve the stability of the pressure ring 8 after it is pressed. An inlet valve 11 is provided on the inlet to control the water flow rate.

[0031] For specific implementation details, please refer to [link / reference]. Figure 6 and Figure 7 The drive motor 13 is a waterproof motor. It is fixed to the inner wall of the opening in the water collection tray 10 (not shown in the electrical connection diagram; a conventional method can be used, ensuring the wires are waterproof and the penetration point is sealed). The drive end of the drive motor 13 extends downwards and retracts to connect to the baffle 12. The shape of the baffle 12 matches the opening in the water collection tray 10 so that when the drive end of the drive motor 13 retracts, the baffle 12 is flush with the lower end of the opening, closing it. To improve the sealing when closed, a sealing ring can be provided around the edge of the baffle 12. When the drive end of the drive motor 13 extends, the baffle 12 is lower than the lower end of the opening, opening it. The actual water pressure measured by the pressure sensor 14 is compared with the controller's preset value. If the pressure exceeds the preset value by a small margin, some drive motors 13 can be started to open a portion of the opening; if the pressure exceeds the preset value by a large margin, all drive motors 13 can be started to open all openings. This is done in conjunction with the pre-loaded program in the controller. The control part will not be described further.

[0032] The following is a brief description of some of the methods of using the water treatment adsorption equipment described in this utility model:

[0033] S1: Water inlet and air outlet: Raw water is delivered from the water inlet 1 into the water collection tank 6 through the water pipe and the delivery pump. When there is too much gas in the water, the nut 3 is loosened in the air outlet 4 to release the gas, control the flow rate and prevent air blockage. It can be manually detected and operated.

[0034] S2: Pressure Driven: The water flow rate of the inlet 1 is controlled by the inlet valve 11. When the water volume is low, the water pressure above the water collection plate 10 is lower than the set value, so the opening on the water collection plate 10 is closed. The water volume above the water collection plate 10 is measured by the pressure sensor 14. When the pressure reaches a certain limit, the controller 12 controls the drive motor 13 to run, so that the opening of the water collection plate 10 is opened and the water flows out through the corresponding opening. When the water pressure above the water collection plate 10 drops to the set value, the controller controls the drive motor 13 to drive the baffle 12 on the water collection plate 10 to close the opening upward.

[0035] S3: Adsorption and Filtration: Open the water collection tank 6 by rotating the screw 5, put the filter paper 9 at the bottom of the water collection tank 6 and lay the adsorbent, fix the pressure ring 8 to make the connection tight and leak-proof, the water body passes through the adsorbent and filter paper 9 to remove impurities in the water and reduce the COD content, and finally the water body is discharged from the outlet 2 to complete the water purification process.

[0036] Example 2

[0037] The difference between Embodiment 2 and Embodiment 1 is that, in order to reduce costs and avoid installing a drive motor 13 and a baffle 12 in each opening of the water collection tray 10, the baffle 12 below each opening in Embodiment 2 is an integral baffle structure. This is similar to the closing and opening method in prior art CN204899054U. See also... Figure 8 and Figure 9 The baffle 12 is flat and parallel to the water collection tray 10. The baffle 12 slides and is sealed against the lower surface of the water collection tray 10. A single drive motor 13 is fixedly mounted on the outer side of the upper section. The drive end of the drive motor 13 extends horizontally into the upper section, sliding and sealing against the side wall of the upper section. The drive end of the drive motor 13 is fixedly connected to the edge of the baffle 12. The drive end of the drive motor 13 extends and retracts to drive the baffle 12 to slide horizontally. When extended, the baffle 12 completely covers all openings; when retracted, the baffle 12 completely or partially offsets the openings, thus opening all or some of the openings. Each opening is suitable for the middle of the water collection tray 10 to accommodate the stroke of the drive end of the drive motor 13 and prevent the baffle 12 from contacting the inner wall of the upper section when it is not completely offset from the openings.

[0038] In practice, to prevent the drive end of the drive motor 13 and the baffle 12 from being subjected to downward water pressure for extended periods, which could affect the lifespan of the drive motor 13 and the sealing performance of the baffle 12 to the opening, a guide rail groove (not shown in the figure) for sliding connection of the baffle 12 can be provided on the lower surface of the water collection tray 10. The baffle 12 is horizontally slidably inserted into the guide rail groove. Alternatively, the baffle 12 can also be horizontally (sliding and sealingly attached) on the upper surface of the water collection tray 10 (i.e., a baffle 12 capable of opening and closing the opening is provided on the side of the opening facing the upper closed end), and the position of the drive motor 13 and its drive end is correspondingly shifted upwards, so that the baffle 12 can be supported by the water collection tray 10 during use, improving its lifespan and sealing effect.

[0039] This utility model is not limited to the above-described embodiments. Any structure that is the same as or similar to the above-described embodiments of this utility model is within the protection scope of this utility model.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
