Description

Technical Field

[0001] This utility model relates to the field of biofilter technology, and in particular to a biofilter with biological packing material. Background Technology

[0002] Biological filters are highly efficient water purification devices widely used in aquaculture. Their core component is the biological packing material, which provides an attachment surface for microorganisms to form a biofilm. Through the metabolism of these microorganisms, pollutants such as organic matter and ammonia nitrogen in the water are decomposed. After aquaculture water enters the filter, it flows through the biological packing material. Microorganisms attach to the surface of the packing material, forming a biofilm that decomposes pollutants. The purified water is then discharged from the filter. Various types of biological packing materials are available, including fixed packing materials (such as plastic balls and ceramic rings), suspended packing materials (such as polyethylene foam and polyurethane foam), and combined packing materials. These packing materials have a high specific surface area, significantly increasing the contact opportunities between water and microorganisms and improving purification efficiency.

[0003] Over time, biofilms age and lose activity. Suspended solids, organic matter, and inorganic matter in the water gradually accumulate on the surface of the packing material, causing blockage and affecting purification efficiency. The packing material needs to be cleaned. Biological packing materials usually have complex geometries and high specific surface areas, making them inconvenient to clean. Furthermore, the biological packing material accumulated in the filter bed increases the difficulty of cleaning. Therefore, we propose a biological packing material biofilter to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a biological filter with biological packing material.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a biological filter bed with biological packing material, comprising a base, a movable frame, a pump casing, a support pipe, a filter bed, a motor, and a screw. The filter bed is disposed above the base, and a grid cylinder is disposed inside the filter bed. Sealing rings are embedded in both ends of the filter bed. Support pipes are disposed at both ends of the grid cylinder, and gear rings are sleeved on the outer walls of the support pipes. The filter bed is cylindrical, and a discharge pipe is disposed at the lower end of the filter bed. A motor is disposed at one end of the filter bed, and a gear that meshes with the gear ring is sleeved on the outer wall of the motor output end. A movable frame is disposed on one side above the base, and a pump casing is fixedly disposed above the movable frame. A pump shaft is rotatably mounted inside the pump casing, and an impeller rotatably mounted inside the pump casing is sleeved on the outer wall of the pump shaft. Discharge ports are equidistantly distributed on the outer wall of the support pipe.

[0006] Preferably, an aeration pipe is rotatably mounted between the pump casing and the support pipe, with a portion of the aeration pipe located inside the support pipe. Because the aeration pipe is rotatably mounted to the support pipe, the aeration pipe remains stable when the support pipe rotates.

[0007] Preferably, the outer wall of the aeration pipe has aeration holes that are evenly distributed. Gas is output from multiple points inside the grid cylinder through these aeration holes.

[0008] Preferably, the motor output end is provided with a docking seat, and one end of the pump shaft is provided with a docking block that engages with the docking seat. The docking seat engages with the docking block, and the rotational force of the motor output end is transferred to the pump shaft.

[0009] Preferably, symmetrical guide rails are fixed on one side above the base of the shuttle, and a slider is slidably installed inside the guide rails at the lower end of the movable frame. The movable frame is slidably supported by the slider sliding inside the guide rails.

[0010] Preferably, a bearing bracket is provided at the upper end of the base, a screw is rotatably mounted inside the bearing bracket, and a nut is provided at the lower end of the movable frame for threaded connection with the screw. The screw receives rotatable support inside the bearing bracket.

[0011] Preferably, a limiting block is provided at one end of the screw, and rotating rods arranged in a circular array are provided on the outer wall of the screw. Gripping the rotating rods facilitates the application of rotational force to the limiting block, and the limiting block prevents the nut from disengaging from the screw.

[0012] Preferably, the filter tank has an inspection port at its upper end, and an inspection cover is provided at the upper end of the inspection port. The inspection cover is connected to the filter tank by bolts. Workers can maintain the interior of the filter tank through the inspection port and control the opening and closing of the inspection port through the inspection cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model introduces aquaculture water into the filter tank through a support pipe. The filter tank is filled with packing material inside the grid cylinder. The aquaculture water is discharged from the center of the packing material. When passing through the packing material, microorganisms attach to the surface of the packing material to form a biofilm, which decomposes the pollutants in the passing aquaculture water. Finally, the purified water is discharged from the filter tank's discharge pipe. During the cleaning process, clean water is introduced through the support pipe and discharged from the center of the packing material to rinse the packing material. The grid cylinder can rotate during the rinsing process to help the packing material flow, making the packing material easy and effective to clean. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, this utility model proposes a biological filter with biological packing material. The biological filter includes a base 1, a movable frame 4, a pump casing 6, a support pipe 8, a filter 10, a motor 13, and a screw 21. The filter 10 is arranged above the base 1. The filter 10 has a grid cylinder 16 inside. Sealing rings 9 are embedded in both ends of the filter 10. Support pipes 8 are arranged at both ends of the grid cylinder 16. A toothed ring 14 is sleeved on the outer wall of the support pipe 8. The filter 10 is cylindrical. A discharge pipe 2 is arranged at the lower end of the filter 10. The motor 13 is arranged at one end of the filter 10. A gear 26 that meshes with the toothed ring 14 is sleeved on the outer wall of the output end of the motor 13.

[0023] Based on the implementation steps of Example 1: the aquaculture water is input into the grid cylinder 16 through the support pipe 8 and output through the discharge port 17. The water flows through the biological packing, and microorganisms attach to the surface of the packing to form a biofilm, decomposing pollutants. Finally, the purified water is output from the discharge pipe 2 through the packing. It is worth noting that the two ends of the support pipe 8 are closed. A cleaning pipe is rotatably installed at one end of the support pipe 8. The cleaning pipe transports clean water. The stable use of the cleaning pipe is ensured while the support pipe 8 rotates.

[0024] Motor 13 drives gear 26 to rotate, gear 26 pushes gear ring 14, which in turn drives grid cylinder 16 to rotate. The packing inside grid cylinder 16 flows, and clean water is transported through support pipe 8 to rinse the packing. The rinsed dirt is transported to the outside through discharge pipe 2, realizing convenient cleaning of the packing. In addition, the sewage and purified sewage in the cleaning process are intercepted by the cylindrical filter tank 10 to prevent water leakage.

[0025] like Figures 1-5 As shown, compared with Embodiment 1, the biological filter with biological packing proposed in this utility model further includes: a movable frame 4 is provided on one side above the base 1, a pump casing 6 is fixed on the movable frame 4, a pump shaft 5 is rotatably installed inside the pump casing 6, an impeller 22 is rotatably installed inside the pump casing 6 and sleeved on the outer wall of the pump shaft 5, and the outer wall of the support pipe 8 is provided with equally spaced discharge ports 17.

[0026] An aeration pipe 12 is rotatably installed between the pump casing 6 and the support pipe 8, and a section of the aeration pipe 12 is located inside the support pipe 8.

[0027] The outer wall of the aeration pipe 12 is provided with aeration holes 18 that are evenly distributed.

[0028] The output end of the motor 13 is provided with a docking seat 3, and one end of the pump shaft 5 is provided with a docking block 7 that fits into the docking seat 3;

[0029] A symmetrical guide rail 20 is fixed on one side above the base 1, and a slider 19 is slidably installed inside the guide rail 20 at the lower end of the movable frame 4.

[0030] The upper end of the base 1 is provided with a bearing bracket 15, and a screw 21 is rotatably installed inside the bearing bracket 15. The lower end of the movable frame 4 is provided with a nut 24 that is threadedly connected to the screw 21.

[0032] The filter tank 10 has an inspection port at its upper end, and an inspection cover 11 is provided at the upper end of the inspection port. The inspection cover 11 is connected to the filter tank 10 by bolts.

[0033] In this embodiment, the gripping rod 25 drives the screw 21 to rotate. Because the moving frame 4 slides inside the guide rail 20 through the slider 19, it is guided by sliding. The screw 21 pushes the nut 24, thereby driving the moving frame 4 to slide. The moving frame 4 drives the pump casing 6 to slide, so that the docking block 7 and the docking seat 3 are engaged. At this time, the output force of the motor 13 acts on the pump shaft 5, driving the impeller 22 to rotate and generate suction force, drawing outside air into the aeration pipe 12 and delivering it to the outside through the aeration hole 18. The aeration structure provides oxygen to the filter tank 10, promoting the growth and metabolism of aerobic microorganisms, improving purification efficiency, and avoiding the use of additional electrical equipment, reducing the cost of use and subsequent maintenance.

[0034] The above specific embodiments are merely several preferred embodiments of this utility model.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
