Description

Technical Field

[0001] This utility model relates to the field of purification technology, and in particular to a multi-stage biological purification tank. Background Technology

[0002] Globally, with the acceleration of industrialization and urbanization, and the rapid growth of the population, the demand for water resources is showing an unprecedented upward trend. However, at the same time, the discharge of industrial wastewater, the overuse of agricultural chemicals, and the discharge of untreated domestic sewage have exacerbated the deterioration of water quality. This situation has not only led to a significant reduction in the amount of available clean water resources, but also caused serious damage to the ecological environment and posed a potential threat to public health due to the direct entry of untreated or insufficiently treated wastewater into natural water bodies.

[0003] The main challenges faced by traditional water treatment technologies include low treatment efficiency, especially in removing drug residues, heavy metals and other pollutants that are difficult to degrade, often failing to meet strict water quality standards. In addition, commonly used purification media, such as sand filters and activated carbon, are prone to accumulating impurities after long-term operation, leading to pore blockage. This not only reduces the water purification efficiency and flow rate, but also increases the difficulty and cost of system maintenance. Utility Model Content

[0004] Existing water purification methods suffer from low treatment efficiency and high maintenance costs after the purification medium becomes clogged. To overcome these problems, this invention provides a multi-stage biological purification tank.

[0005] Technical Solution: A multi-stage biological purification tank includes a frame and a purification tank. The frame serves as the supporting carrier for this preferred tank. The purification tank is mounted on top of the frame. The top and bottom of the purification tank are respectively provided with an inlet and an outlet. The side wall of the purification tank has two openings. The tank also includes: an aerator installed on the lower part of the side wall of the purification tank; two placement blocks, spaced apart vertically inside the purification tank, each placement block being C-shaped with a slot on its front side, and each slot containing a filter screen; and two sliding frames that slide through the openings in the side wall of the purification tank. The following components are installed in the slots of the placement blocks: an activated carbon plate, installed on the sliding frame and assembled into the slots of the upper placement block; a microbial purification packing material, installed on the sliding frame and assembled into the slots of the lower placement block, which, in conjunction with the aerator, allows the microorganisms inside to fully contact the oxygen provided by the aerator and accelerate their growth and activity, thereby decomposing organic matter in the wastewater to achieve the effect of biological purification; and a pressurization component, installed on the frame, which is used to inject air from the top of the purification tank downwards to pressurize and accelerate water filtration.

[0006] Furthermore, it is particularly preferred that both the placement block and the sliding frame are provided with sealing strips at their edges. After the sliding frame is pushed into the purification tank and installed on the placement block, the activated carbon plate and the microbial purification packing can effectively filter wastewater.

[0007] Furthermore, it is particularly preferred that the pressurization assembly includes an air inlet pipe, a piston cylinder, a cylinder, and a piston rod. The air inlet pipe is connected to the top of the purification tank and is a rigid pipe. The piston cylinder is connected to the lower end of the air inlet pipe. The cylinder is fixedly installed at the bottom of the frame. The piston rod is slidably disposed inside the piston cylinder. The piston cylinder and the piston rod form a piston structure. The cylinder pushes the piston rod inside the piston cylinder, causing the piston cylinder to pressurize air through the air inlet pipe into the purification tank, thereby increasing the air pressure and improving the filtration efficiency of the wastewater in the purification tank.

[0008] Furthermore, it is particularly preferred that a limiting plate is also included, which is installed at the slot of the upper placement block, and the limiting plate is used to stably limit the activated carbon plate within the corresponding sliding frame.

[0009] Furthermore, it is particularly preferred that the device also includes guide rods, sliding plates, springs, connecting plates, and driving components. The guide rods are symmetrically installed on the outer shell of the sliding frame, and each guide rod has a limiting protrusion at its end. The sliding plate is slidably connected to the guide rods. The springs are all sleeved on the guide rods between the sliding plate and the sliding frame. The connecting plates are symmetrically fixed to the ends of the sliding plates. The driving components are installed on the outer wall of the purification tank. The driving components are used to drive the sliding plate to press the springs, and the springs press against the sliding frame, so that the sliding frame can be stably installed inside the placement block.

[0010] Furthermore, it is particularly preferred that the driving component includes an electric push rod and a telescopic rod. The electric push rod is fixedly installed on one side of the outer wall of the purification tank, and the push rod of the electric push rod is connected to the corresponding connecting plate on the same side. The telescopic rod is fixedly installed on the other side of the outer wall of the purification tank, and the telescopic rod is connected to the corresponding connecting plate on the same side.

[0011] Beneficial effects:

[0012] 1. This utility model adopts a multi-stage purification structure, including the combined use of activated carbon plates and microbial purification packing, which can effectively remove organic pollutants and some inorganic pollutants from water. The activated carbon plates can adsorb organic matter, odors and some heavy metals in the water, while the microbial purification packing can remove recalcitrant organic matter through biodegradation, thereby improving the purification effect of wastewater.

[0013] 2. This utility model, through the design of a sliding frame structure, allows the activated carbon plate and microbial purification packing to be easily removed from the purification tank for cleaning or replacement, reducing maintenance workload. In addition, a sealing strip is provided between the sliding frame and the placement block to ensure that there is no wastewater leakage during the filtration process, thereby improving the airtightness and reliability of the system.

[0014] 3. This utility model can also inject compressed air into the purification tank through the piston structure to generate positive air pressure, which helps to accelerate the speed at which wastewater passes through the filter material, thereby improving the filtration rate of the entire system, shortening the treatment time, and effectively improving the efficiency of sewage purification.

Detailed Implementation

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0021] Example: A multi-stage biological purification tank, such as Figures 1-4As shown, the device includes a frame 1 and a purification tank 2. The frame 1 serves as the supporting carrier for this preferred tank. The purification tank 2 is installed on top of the frame 1. The top and bottom of the purification tank 2 are respectively provided with an inlet 3 and an outlet 4. The side wall of the purification tank 2 has two openings. The device also includes: an aerator 5, installed on the lower part of the side wall of the purification tank 2; two placement blocks 7, spaced apart vertically inside the purification tank 2, each placement block 7 being a C-shaped block with a slot on its front side, and each slot containing a filter screen; two sliding frames 6, slidably installed in the slots of the placement blocks 7 through the openings in the side wall of the purification tank 2; and an activated carbon plate 8, installed on the sliding frames 6 and assembled onto the upper placement block 7. The microbial purification packing 9 is installed on the sliding frame 6 and assembled into the slot of the lower placement block 7. The microbial purification packing 9 works with the aerator 5 to allow the microorganisms inside to fully contact the oxygen provided by the aerator 5 and accelerate their growth and activity, thereby decomposing the organic matter in the wastewater to achieve the effect of biological purification. A pressurizing component is installed on the frame 1. The pressurizing component is used to inject air from the top of the purification tank 2 downwards to pressurize and accelerate the filtration of water. Sealing strips are provided at the edges of the placement block 7 and the sliding frame 6. After the sliding frame 6 is pushed into the purification tank 2 and installed on the placement block 7, the activated carbon plate 8 and the microbial purification packing 9 can effectively filter the wastewater.

[0022] like Figure 1 As shown, the pressurization assembly includes an air inlet pipe 10, a piston cylinder 101, a cylinder 11, and a piston rod 12. The air inlet pipe 10 is connected to the top of the purification tank 2 and is a rigid pipe. The piston cylinder 101 is connected to the lower end of the air inlet pipe 10. The cylinder 11 is fixedly installed at the bottom of the frame 1. The piston rod 12 is slidably disposed inside the piston cylinder 101. The piston cylinder 101 and the piston rod 12 form a piston structure. The cylinder 11 pushes the piston rod 12 to move inside the piston cylinder 101, causing the piston cylinder 101 to pressurize air through the air inlet pipe 10 into the purification tank 2, thereby increasing the filtration efficiency of the wastewater in the purification tank 2.

[0023] like Figure 3 As shown, the limiting plate 13 is installed at the slot of the upper placement block 7, and the limiting plate 13 is used to stably limit the activated carbon plate 8 within the corresponding sliding frame 6.

[0024] like Figure 4As shown, the guide rod 15 is symmetrically installed on the outer shell of the sliding frame 6. The end of the guide rod 15 is provided with a limiting protrusion. The sliding plate 14 is slidably connected to the guide rod 15. The springs 16 are all sleeved on the guide rod 15 between the sliding plate 14 and the sliding frame 6. The connecting plate 17 is symmetrically fixed to the end of the sliding plate 14. The driving component is installed on the outer wall of the purification tank 2. The driving component is used to drive the sliding plate 14 to press the springs 16, so that the springs 16 are pressed on the sliding frame 6, so that the sliding frame 6 can be stably installed in the placement block 7.

[0025] like Figure 1 and Figure 4 As shown, the driving component includes an electric push rod 18 and a telescopic rod 19. The electric push rod 18 is fixedly installed on one side of the outer wall of the purification tank 2, and the push rod of the electric push rod 18 is connected to the corresponding connecting plate 17 on the same side. The telescopic rod 19 is fixedly installed on the other side of the outer wall of the purification tank 2, and the telescopic rod 19 is connected to the corresponding connecting plate 17 on the same side.

[0026] When using this preferred tank for multi-stage wastewater purification, wastewater is injected into the purification tank 2 through the inlet 3 via a pipe. The wastewater flows downwards onto the activated carbon plate 8 placed in block 7. The activated carbon plate 8 adsorbs and removes organic pollutants, odors, and other harmful substances from the wastewater. Since the rate of natural downward permeation filtration of wastewater onto the activated carbon plate 8 is slow, the cylinder 11 is activated. The extension rod 19 of the cylinder 11 drives the piston rod 12 to pull and blow air in the piston cylinder 101, allowing the piston cylinder 101 to introduce gas into the purification tank 2 through the air inlet pipe 10. When the air pressure component at the top of the purification tank 2 increases, the wastewater on the activated carbon plate 8 can pass through the activated carbon plate 8 more quickly under the action of air pressure, thus achieving primary filtration of the wastewater. After activating the aerator 5, the aerator 5 provides sufficient oxygen into the purification tank 2. The oxygen fully contacts the microbial purification packing 9, causing the microorganisms in the microbial purification packing 9 to grow and multiply rapidly. When the primary filtered wastewater flows into the lower layer of microbial purification packing 9, the packing... The microorganisms on the material can effectively degrade organic pollutants in wastewater, breaking down complex organic molecules into harmless carbon dioxide and water through biochemical reactions, thereby achieving secondary water purification. Finally, the purified water that meets the standards can be discharged from the drain outlet 4. When the activated carbon plate 8 and the microbial purification packing 9 need to be cleaned or replaced, the electric push rod 18 is activated. The push rod of the electric push rod 18 extends and pushes the connecting plate 17. Under the guidance of the telescopic rod 19, the connecting plate 17 pushes the sliding plate 14. The sliding plate 14 drives the guide rod 15 and pulls out the sliding frame 6, so that the sliding frame 6 slides out from the placement block 7 in the purification tank 2. Then, the activated carbon plate 8 and the microbial purification packing 9 can be removed from the sliding frame 6 for cleaning or replacement. Then, the activated carbon plate 8 and the microbial purification packing 9 are put back into the sliding frame 6. When the electric push rod 18 pushes them back into the purification tank 2 through the sliding plate 14, the spring 16 limits and squeezes them onto the sliding frame 6, so that the sliding frame 6 can be tightly attached to the placement block 7, preventing the sliding frame 6 from loosening and leaking in the purification tank 2.
