Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 7 As shown, a combined biological filter includes a vertically placed tank 1. Four mounting slots 3 are installed on the side wall of the tank 1 from top to bottom, and each of the four slots houses a packing tray 7. The packing tray 7 is U-shaped, with its outer wall fitting flush with the inner wall of the tank 1. One side of the top surface of the packing tray 7 is recessed downwards to form a holding section, which is filled with different packing materials. The packing material can be selected from one of the following: quartz sand, zeolite, ceramsite, fiber resin, maifanite, crushed stone, vermiculite, or artificial coral. A sealing plate 5 is installed at one end of each of the four packing trays 7, and all four are connected to the mounting slots by bolts. The edge of the opening 3 is fixedly connected. The top surface of each of the four packing trays 7 is equipped with a perforated mesh plate 15. A conical disc 8 is installed between the two upper packing trays 7. The edge of the top of the disc is fixedly connected to the tank body 1. A vertical pipe 16 is installed in the middle of the bottom surface of the conical disc 8. An installation box 21 is installed on one side of the outer wall of the vertical pipe 16. A fixing plate 17 is installed at the end of the installation box 21. A proximity switch 18 is installed on one side of the inner wall of the installation box 21. An impeller 13 is rotatably installed in the middle of the outer wall of the vertical pipe 16. The middle of the impeller 13 protrudes outward and extends into the interior of the installation box 21, and a protrusion 19 is installed at its end.

[0024] An LED light 2 is installed in the middle of the outer wall of the tank body 1, which is electrically connected to a proximity switch 18 via a wire. Arc-shaped support strips 14 are installed inside the tank body 1 near the mounting slot 3. As an optional technical solution of this utility model, the arc-shaped support strips 14 facilitate the support of the protruding end of the packing tray 7, and at the same time limit the installation of the packing tray 7 to ensure its stability after installation. Meanwhile, the packing tray 7 is U-shaped, and its outer wall fits tightly with the inner wall of the tank body 1. In order to ensure the sealing of the joint surface, a sealing gasket can be installed at the edge of the bottom surface of the packing tray 7. Then, the sealing gasket is pressed by the weight of the packing tray 7 itself and the pressure of the water flow, thereby improving the sealing performance.

[0025] The bottom end of the outer circumferential surface of the tank body 1 is provided with an air inlet valve 20, and the bottom end of the tank body 1 is provided with a discharge control valve 4; as an optional technical solution of the utility model, one side of the air inlet valve 20 is provided with a pipeline and extends into the inside of the tank body 1, and the exposed end of the air inlet valve 20 is connected with an external oxygen supply device, thereby facilitating the introduction of oxygen into the inside of the tank body 1 during the filtering stage, facilitating the growth of microorganisms, and at the same time, the air inlet valve 20 adopts a one-way valve, that is, oxygen can only be introduced into the inside of the tank body 1, so that water cannot flow out of the discharge control valve 4, thereby facilitating the control of the speed of water flow, adjusting the water flow speed according to the filtering requirement, and ensuring that the microorganisms can fully decompose the harmful substances in the water.

[0026] The edges of the four mounting slots 3 are all outwardly folded, and the edges of the four mounting slots 3 are all outwardly folded.

[0027] The bottom surface of the inner wall of the four filler trays 7 is provided with a plurality of holes for water flow, and the side wall edges of the filler trays 7 are all in a stepped shape.

[0028] The bottom end of the vertical pipe 16 is provided with a flow baffle 12, and a gap is left between the bottom surface of the flow baffle 12 and the punched mesh plate 15 in the middle.

[0029] The combined biological filter needs the following steps when in use:

[0030] 1) When in use, the pond water flows into the tank body 1 from the top end, and passes through the four filler trays 7 in sequence under the action of water flow pressure and gravity;

[0031] 2) The four fillers are made of different materials, thereby providing a growth environment for microorganisms, and the microorganisms decompose the harmful substances contained in the water flow;

[0032] 3) After the water flows through the conical disc 8, it flows out from the vertical pipe 16 and impacts the impeller 13, causing the impeller 13 and the protrusion 19 to rotate synchronously. When the protrusion 19 approaches the proximity switch 18, the LED light 2 lights up. The flashing frequency of the LED light 2 is used to determine whether the packing material is under pressure.

[0033] 4) When the LED light 2 flashes at a reduced frequency, the water flow can be blocked. At the same time, the bolts on one side of the sealing plate 5 can be removed to facilitate the removal of the packing tray 7 and the replacement of the packing.

[0034] In summary, during operation, the tank body 1 has four mounting slots 3 on its side, each containing a packing tray 7. Each packing tray 7 contains packing material, thus dividing the packing material from top to bottom and forming individual units. A sealing plate 5 is installed on one side of each packing tray 7. By unscrewing the bolts at its edge, the packing tray 7 and packing material can be pulled out as a whole, allowing the perforated mesh plate 15 to be removed, facilitating packing replacement. Furthermore, each layer of packing tray 7 is independent and does not interfere with the others, significantly reducing operation time and improving material replacement efficiency. The overall structure is simple and easy to promote and use. Then, by setting up a conical disc 8, a vertical pipe 16, an impeller 13, a mounting box 21, and a fixing plate 17, the impeller 13 is rotatably mounted on one side of the bottom of the vertical pipe 16, with its end entering the interior of the mounting box 21. A protrusion 19 is installed at its end. A proximity switch 18 is installed on the inner wall of the mounting box 21 near the protrusion 19. The proximity switch 18 is electrically connected to the LED light 2. When the packing inside the tank 1 decomposes and compacts, the water flow rate decreases, the impact force on the impeller 13 decreases, and the corresponding flashing frequency of the LED light 2 decreases. This makes it easier for the operator to remove the four packing trays 7 and replace the problematic packing.
