Description

Technical Field

[0001] This utility model belongs to the field of biological purification packing technology, specifically involving multi-channel biological purification packing. Background Technology

[0002] Biological packing materials, as a water purification technology, have broad application prospects in the field of water purification in plateau wetlands. By providing a suitable environment for microbial growth, biological packing materials promote the reproduction and metabolic activities of microorganisms, thereby achieving the degradation and removal of pollutants. Compared with traditional physical and chemical methods, biological packing material technology has significant advantages. First, biological packing material technology utilizes the metabolic activities of microorganisms to degrade pollutants without the need to add any chemical agents, thus avoiding secondary pollution. Second, biological packing material technology can continuously provide purification services for wetlands. Microorganisms continuously reproduce and metabolize in the packing material, forming a stable biofilm system that can effectively degrade pollutants over a long period of time. Finally, biological packing material technology is inexpensive, requires no complex equipment or technical support, and is easy to promote and apply.

[0003] Existing biological packing materials are generally designed in a ring shape to increase the effective area. However, spherical shapes take up more space during transportation, making them inconvenient to transport. They are also easily damaged by compression, resulting in a high scrap rate after transportation. This affects the normal operation of recirculating aquaculture and reduces their applicability. Utility Model Content

[0004] The purpose of this invention is to provide a multi-channel biological purification packing material to solve the problems mentioned in the background art. Existing biological packing materials are generally designed as ring-shaped to increase the effective area, but as spherical, they occupy a large space during transportation, making transportation inconvenient. They are also easily crushed and damaged, resulting in a high scrap rate after transportation, which affects the normal operation of recirculating aquaculture and reduces the scope of application.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes an annular packing shell and a support cylinder with an opening on the upper surface of the packing shell. Several material pieces (first type) are mounted on the outer surface of the support cylinder. One end of each material piece (first type) is fixedly connected to the packing shell. Two arc-shaped material pieces (second type) are installed between two adjacent material pieces (first type). A fitting post is provided inside the support cylinder. Several spreading plates are hinged to the upper surface of the packing shell. One end of each spreading plate is hinged to the fitting post. A through hole is provided on the fitting post. Two fixing plates are installed in the through hole. A sliding rod is slidably mounted on the fixing plate. A baffle is installed on the opposite side of each of the two sliding rods. A fixing pin is installed on the opposite side of each of the two sliding rods. One end of each fixing pin has an arc-shaped surface. Fixing grooves that cooperate with the fixing pins are provided on the left and right sides inside the support cylinder. One end of each fixing pin extends into the two fixing grooves. A first spring is sleeved on the sliding rod, with both ends fixedly connected to the baffle and the fixing plate respectively.

[0006] By adopting the above scheme, a support cylinder, a fitting column, a first spring, and a fixing pin are set up. The fixed plate provides sliding support for the slide rod. Combined with the function of the first spring and the fixing pin, the fitting column is fixed on the support cylinder. The fitting column can move up and down. The hinged connection of the opening plate facilitates the upward movement of the fitting column. One end of the opening plate moves with it, and the opening plate gradually tilts, thereby reducing the area of ​​the packing shell, reducing the space occupied, facilitating transportation, preventing the packing shell from being squeezed and damaged, and improving the applicability.

[0007] In a preferred embodiment, a connecting cylinder is installed on the upper surface of the fitting column, and a connecting column is installed on the lower surface of the support cylinder, with the connecting column and the connecting cylinder arranged in a cooperative manner.

[0008] By adopting the above scheme, by setting up connecting columns and connecting cylinders, and utilizing the matching effect of the size of the connecting columns with the interior of the connecting cylinders, multiple packing shells can be easily connected together, thereby increasing the area of ​​the packing shells. The structure is simple and the operation is convenient.

[0009] In a preferred embodiment, a rotating column is rotatably mounted on the right side of the upper surface of the connecting cylinder, and a circular cover plate is mounted on the rotating column, the outer diameter of the cover plate being larger than the inner diameter of the connecting cylinder.

[0010] By adopting the above scheme, a rotating column and a cover plate are set up. The rotating column provides rotational support for the cover plate. Combined with the fact that the outer diameter of the cover plate is larger than the inner diameter of the connecting cylinder, it is convenient to cover and reset the opening of the connecting cylinder, so as to avoid the accumulation of dirt or water inside the connecting cylinder, thereby ensuring the cleanliness of the inside of the connecting cylinder and allowing the connecting column to quickly enter the connecting cylinder.

[0011] In a preferred embodiment, four second springs are installed on the inner bottom surface of the support cylinder, and the top of the four second springs is equipped with the same movable plate. A positioning component is provided on the upper surface of the movable plate.

[0012] By adopting the above scheme, a second spring and a movable plate are set up. The second spring provides elastic support for the movable plate. Combined with the function of the movable plate, it is convenient for the mating column to move upward and out of the support cylinder. The movable plate is driven by the elasticity of the second spring to move to a position flush with the upper surface of the support cylinder, thereby avoiding the accumulation of a lot of garbage in the support cylinder that would hinder the movement of the mating column.

[0013] In a preferred embodiment, the positioning component includes four positioning pins, all of which are mounted on the lower surface of the interlocking column. The upper surface of the movable plate has four positioning grooves that cooperate with the positioning pins, and the bottom end of each positioning pin extends into the positioning groove.

[0014] By adopting the above scheme, by setting a positioning pin, the bottom end of the positioning pin enters the positioning groove to initially control the bottom end of the mating column to engage with the movable plate, thereby preventing the mating column from moving downwards and improving the stability of the bottom end of the mating column.

[0015] In a preferred embodiment, a support rod is installed on the inner bottom surface of the support cylinder, the top end of the support rod abuts against the movable plate, and three rubber rings are installed on the outer surface of the connecting column.

[0016] By adopting the above solution, a support rod is set up, and the top of the support rod abuts against the movable plate, which restricts the downward movement of the movable plate. This ensures that the position where the movable plate stops after moving downward is exactly where one end of the fixing pin enters the groove, thus greatly facilitating the movement of the fixing pin and preventing misalignment of the fixing pin.

[0017] In a preferred embodiment, an annular interceptor plate is installed on the outer surface of the interlocking column, and the lower surface of the interceptor plate is in contact with the upper surface of the support cylinder.

[0018] By adopting the above scheme, by setting up an intercepting plate, the upper surface of the support cylinder is blocked and covered by the ring-shaped intercepting plate. When the interlocking column is subjected to external force and enters the support cylinder, it drives the intercepting plate to move and cover the upper surface of the support cylinder.

[0019] In a preferred embodiment, a telescopic rod is provided inside the second spring, the telescopic rod is installed inside the support cylinder, and the telescopic shaft of the telescopic rod is fixedly connected to the movable plate.

[0020] By adopting the above solution, a telescopic rod is installed to fill the interior of the second spring, thereby improving the fullness of the second spring and preventing deformation when the second spring is squeezed or stretched by the movable plate. This extends the service life of the second spring and allows it to provide long-term and stable elastic support to the movable plate.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This multi-channel biological purification packing material is designed with a support cylinder, a fitting column, a first spring, and a fixing pin. The fixed plate provides sliding support for the sliding rod, and the fitting column is fixed to the support cylinder by the first spring and the fixing pin. The fitting column can move up and down, and the hinged connection of the opening plate facilitates the upward movement of the fitting column. One end of the opening plate moves with the fitting column, and the opening plate gradually tilts, thereby reducing the area of ​​the packing shell, reducing the space occupied, facilitating transportation, preventing the packing shell from being crushed and damaged, and improving the applicability.

[0023] This multi-channel biological purification packing uses a rotating column and a cover plate. The rotating column provides rotational support for the cover plate, and the outer diameter of the cover plate is larger than the inner diameter of the connecting cylinder. This facilitates the sealing and resetting of the opening of the connecting cylinder, preventing dirt or water from accumulating inside the connecting cylinder. This ensures the cleanliness of the inside of the connecting cylinder and allows the connecting column to quickly enter the connecting cylinder. Attached Figure Description

[0028] Please see Figure 1-3This utility model provides a multi-channel biological purification packing, including an annular packing shell 1 and a support cylinder 2 with an opening on the upper surface of the packing shell 1. The support cylinder 2 accommodates a fitting column 19. Several material pieces 4 are installed on the outer surface of the support cylinder 2. One end of each material piece 4 is fixedly connected to the packing shell 1. Two arc-shaped material pieces 3 are installed between two adjacent material pieces 4. The fitting column 19 is provided inside the support cylinder 2, and a fixing plate 7, a sliding rod 8, and a first spring 10 are accommodated through holes in the fitting column 19. Several expansion plates 5 are hinged to the upper surface of the packing housing 1. These expansion plates 5 are used to expand the packing housing 1. One end of each expansion plate 5 is hinged to a fitting post 19. The fitting post 19 has a through hole, and two fixing plates 7 are installed inside the through hole. The fixing plates 7 provide sliding support for the sliding rod 8. The sliding rod 8 is slidably installed through the fixing plate 7, and it provides fixed support for the fixing pin 11 and the baffle 9. Baffles 9 are installed on opposite sides of the two sliding rods 8, and these baffles 9 provide support for one end of the sliding rod 8. The two sliding rods 8 are sealed off, and fixing pins 11 are installed on their opposite sides. The fixing pins 11 are used to fix the position of the fitting post 19. One end of the fixing pin 11 is provided with an arc-shaped surface. The left and right sides of the support cylinder 2 are provided with fixing grooves that cooperate with the fixing pins 11. One end of each of the two fixing pins 11 extends into the two fixing grooves. A first spring 10 is sleeved on the sliding rod 8, and its two ends are fixedly connected to the baffle 9 and the fixing plate 7 respectively. The first spring 10 provides elastic support for the positioning pin 16. By setting the support cylinder 2 The fitting column 19, the first spring 10, and the fixing pin 11, along with the fixing plate 7, provide sliding support for the slide rod 8. Combined with the action of the first spring 10 and the fixing pin 11, the fitting column 19 is fixed to the support cylinder 2. The fitting column 19 can move up and down. The hinged connection of the opening plate 5 facilitates the upward movement of the fitting column 19. One end of the opening plate 5 moves along with it, and the opening plate 5 gradually tilts, thereby reducing the area of ​​the packing shell 1, reducing the space occupied, facilitating transportation, preventing the packing shell 1 from being squeezed and damaged, and improving the applicability.

[0029] A connecting cylinder 20 is installed on the upper surface of the interlocking column 19. The connecting cylinder 20 cooperates with the connecting column 17. The connecting column 17 is installed on the lower surface of the support cylinder 2. The connecting column 17 and the connecting cylinder 20 are arranged in a cooperative manner. By setting the connecting column 17 and the connecting cylinder 20, and by utilizing the size of the connecting column 17 and the internal structure of the connecting cylinder 20, it is convenient to connect multiple packing shells 1 together, thereby increasing the area of ​​the packing shell 1. The structure is simple and the operation is convenient.

[0030] A rotating column 21 is rotatably mounted on the right side of the upper surface of the connecting cylinder 20. The rotating column 21 provides rotational support for the cover plate 22. A circular cover plate 22 is mounted on the rotating column 21, which covers the top of the connecting cylinder 20. The outer diameter of the cover plate 22 is larger than the inner diameter of the connecting cylinder 20. By setting the rotating column 21 and the cover plate 22, the rotating column 21 provides rotational support for the cover plate 22. Combined with the fact that the outer diameter of the cover plate 22 is larger than the inner diameter of the connecting cylinder 20, it is convenient to cover and reset the opening of the connecting cylinder 20, preventing stains or water from accumulating inside the connecting cylinder 20, thereby ensuring the cleanliness of the inside of the connecting cylinder 20 and allowing the connecting column 17 to quickly enter the connecting cylinder 20.

[0031] Four second springs 13 are installed on the inner bottom surface of the support cylinder 2. The second springs 13 provide elastic support for the movable plate 12. The top of the four second springs 13 is equipped with the same movable plate 12, which supports the bottom of the fitting column 19. The upper surface of the movable plate 12 is provided with a positioning component. By setting the second springs 13 and the movable plate 12, the second springs 13 provide elastic support for the movable plate 12. Combined with the function of the movable plate 12, when the fitting column 19 moves upward and out of the support cylinder 2, the movable plate 12 is driven by the elasticity of the second springs 13 to move to a position flush with the upper surface of the support cylinder 2, thereby avoiding the accumulation of a lot of garbage in the support cylinder 2 that would hinder the movement of the fitting column 19.

[0032] The positioning component includes four positioning pins 16, which are used to position the bottom end of the mating column 19. All four positioning pins 16 are installed on the lower surface of the mating column 19. The upper surface of the movable plate 12 has four positioning grooves that cooperate with the positioning pins 16. The bottom end of the positioning pin 16 extends into the positioning groove. By setting the positioning pins 16, the bottom end of the positioning pin 16 enters the positioning groove, and the bottom end of the mating column 19 is initially controlled to engage with the movable plate 12. This prevents the mating column 19 from moving downwards and improves the stability of the bottom end of the mating column 19.

[0033] A support rod 15 is installed on the inner bottom surface of the support cylinder 2. The support rod 15 supports the movable plate 12. The top of the support rod 15 abuts against the movable plate 12. Three rubber rings 18 are installed on the outer surface of the connecting column 17. By setting the support rod 15, the space for the movable plate 12 to move downward is restricted by the action of the top of the support rod 15 abutting against the movable plate 12. This ensures that the position where the movable plate 12 stops after moving downward is just right to ensure that one end of the fixing pin 11 enters the groove fixing groove, thereby greatly facilitating the movement of the fixing pin 11 and avoiding the phenomenon of misalignment of the fixed pin 11.

[0034] An annular interceptor plate 6 is installed on the outer surface of the interlocking column 19. The interceptor plate 6 covers the upper surface of the support cylinder 2. The lower surface of the interceptor plate 6 is in contact with the upper surface of the support cylinder 2. By setting the interceptor plate 6, the upper surface of the support cylinder 2 is blocked and covered by the interceptor plate 6, so that when the interlocking column 19 is subjected to external force and enters the support cylinder 2, it drives the interceptor plate 6 to move and cover the upper surface of the support cylinder 2.

[0035] The second spring 13 is equipped with a telescopic rod 14, which fills the interior of the second spring 13. The telescopic rod 14 is installed inside the support cylinder 2, and its telescopic shaft is fixedly connected to the movable plate 12. By setting the telescopic rod 14, the interior of the second spring 13 is filled, thereby improving the fullness of the interior of the second spring 13 and preventing deformation of the second spring 13 when squeezed or stretched by the movable plate 12. This extends the service life of the second spring 13, allowing it to provide long-term and stable elastic support to the movable plate 12.

[0036] In use, when it is necessary to shrink the packing shell 1, rotate the cover plate 22. When the cover plate 22 rotates, it drives the rotating column 21 to rotate, rotating the cover plate 22 to the upper surface of the connecting cylinder 20. Utilizing the matching effect between the size of the connecting column 17 and the interior of the connecting cylinder 20, multiple packing shells 1 can be easily connected together, thereby increasing the area of ​​the packing shell 1. The structure is simple and the operation is convenient. Then, move the fitting column 19 upward. The fitting column 19 moves upward under external force, and the arc-shaped surface of the fixing pin 11 is compressed and extends out of the fixing groove. When the fixing pin 11 moves, it drives the sliding plate to slide on the fixing plate 7. When the sliding rod 8 moves, it stretches the first spring 10. Then, when the fitting column 19 moves, it drives one end of the support plate to move upward. At this time, the spreading plate 5 gradually tilts. The other end of the spreading plate 5 drives the packing shell 1 to shrink towards the middle. When the bottom end of the fitting column 19 moves, it drives one end of the positioning pin 16 to move out of the positioning groove. The fitting column 19 gradually moves away from the movable plate 12, and the movable plate 12 is subjected to... The reaction force of the second spring 13 moves upward, and the movable plate 12 moves away from the support rod 15 to stretch the telescopic rod 14. The action of the top of the support rod 15 against the movable plate 12 restricts the downward movement of the movable plate 12, so that the position where the movable plate 12 stops after moving downward ensures that one end of the fixing pin 11 enters the groove fixing slot, which greatly facilitates the movement of the fixing pin 11 and avoids the phenomenon of misalignment of the fixing pin 11. The movable plate 12 moves to a position flush with the upper surface of the support cylinder 2, thus completing the shrinkage of the filler shell 1. The telescopic rod 14 fills the interior of the second spring 13, thereby improving the fullness of the interior of the second spring 13 and preventing the second spring 13 from deforming when squeezed or stretched by the movable plate 12, thus extending the service life of the second spring 13 and allowing the second spring 13 to provide stable elastic support to the movable plate 12 for a long time.
