Description

Technical Field

[0001] The utility model relates to the technical field of bottom aerators, in particular to a microbial filtering box and a sludge collecting device inside a bottom aerator. Background Art

[0002] The aquaculture industry cannot do without the use of aeration purification devices. Existing aeration devices mainly inject air into the water through fans and aeration plates to increase the oxygen content in the water, which can promote the respiration of cultured organisms, improve growth rate and breeding efficiency, reduce mortality and increase production. These devices usually lack effective water filtering functions, resulting in the inability to effectively remove suspended matter and impurities, and generally cannot collect sludge. The sludge brought up by the stirring plate can easily clog the aeration plate, affecting the oxygenation effect. After clogging, it is easy to cause damage to the equipment and affect the service life of the aeration equipment. Utility Model Content

A sludge collection bucket is movably connected to the front end of the bottom aerator frame, and a collection box is arranged at the lower end of the sludge collection bucket, which can filter the water body and facilitate the attachment of microorganisms. Microorganisms can be used to degrade organic waste and pollutants in the water, purify water quality, improve the breeding environment, and enhance the sustainable development level of the breeding industry. Silt can also be collected to extend the service life of the equipment, ensure the normal operation of the equipment, and have good convenience of use.

[0006] Furthermore, the inner lower end of the collection box is provided with symmetrically distributed lifting rods to facilitate pulling out the collection box.

[0007] Furthermore, the upper end of the bottom aerator frame is provided with symmetrically distributed hanging rings, and the upper end hooks of the lifting rods are extended to the inside of the vertically corresponding hanging rings to facilitate the positioning of the collection box.

[0009] 1. By adding a microbial filtration filter box, it not only has the function of bottom oxygenation, but also realizes the effective filtration of pollutants in the water, thereby greatly improving the purification efficiency of water quality in the water area, reducing water pollution, and improving the stability and health of the aquaculture environment. It is also helpful to degrade organic waste and pollutants in the water, purify water quality, build a stable ecological environment, promote the growth of beneficial microorganisms, increase the biodiversity of water bodies, improve the aquaculture environment, and enhance the sustainable development level of aquaculture.

[0010] 2. After the equipment is started, the surface fan pushes the equipment to perform circular motion. The bubbles generated by the aeration disk increase the oxygen content in the water. The underwater stirring plate realizes water layer exchange. The sludge brought up is collected by the sludge collection bucket into the collection box. The collection box is cleaned by regularly pulling up the lifting rod to ensure the normal operation of the equipment. The sludge collection device can collect sludge in time to prevent it from clogging the explosion disk and other components, thereby ensuring the normal operation of the bottom aerator, extending the service life of the equipment, and ensuring the normal operation of the equipment.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-2 , This embodiment provides a technical solution: a microbial filter box and sludge collection device inside a bottom aerator, including a bottom aerator frame 1;

[0016] Bottom aerator frame 1: a support frame 2 is installed in the middle, and the support frame 2 is fixed by buckles or bolts. The bottom aerator frame 1 provides installation positions for other parts. The support frame 2 is provided with uniformly distributed microbial filtration material boxes 3. The support frame 2 is installed under the fan of the bottom aerator. The inside of the microbial filtration material box 3 can be filled with activated carbon and ceramics, etc., and the same type or different types can be used. There is no order of priority for the filter materials. The microbial filtration material box 3 can filter the water flow passing through, and microorganisms are applied on the surface of the microbial filtration material box 3. Attachment technology improves the water purification effect through microbial decomposition. The front end of the bottom aerator frame 1 is movably connected with a sludge collecting bucket 4. The lower end of the sludge collecting bucket 4 is provided with a collecting box 5. The lower end of the inner part of the collecting box 5 is provided with symmetrically distributed lifting rods 6. The sludge brought up is collected by the sludge collecting bucket 4 into the collecting box 5. The lifting rod 6 is regularly pulled upward to clean the collecting box 5 to ensure the normal operation of the equipment. The upper end of the bottom aerator frame 1 is provided with symmetrically distributed hanging rings 7. The upper end hooks of the lifting rods 6 extend to the inside of the vertically corresponding hanging rings 7. The hanging rings 7 facilitate the positioning of the lifting rods 6 and the collecting box 5.

[0017] The working principle of a microbial filter box and a sludge collection device inside a bottom aerator provided by the utility model is as follows: a support frame 2 is installed below the fan of the bottom aerator, and the interior of the microbial filter material box 3 can be filled with activated carbon and ceramics, etc., and the same type or different types can be used. There is no order of priority for the filter materials. Microbial attachment technology is applied to the surface of the microbial filter material box 3 to improve the water purification effect through microbial decomposition. At the same time, the microbial filter material box 3 uses the honeycomb holes with a concave-convex structure to increase the contact area with the water surface, thereby increasing the surface area for microbial attachment and further improving the water purification effect. The microbial attachment agent is a special chemical or biological material that can enhance the adhesion ability of microorganisms on the filter medium. These attachment agents can be organic or inorganic, usually have adhesion properties, and can attract and capture microorganisms in the water. When water flows through the support frame 2, the microbial attachment agent will form an adhesion layer on the surface of the microbial filtration filter material box 3. This adhesion layer increases the surface area of ​​the microbial filtration filter material box 3 and the residence time of the microorganisms, and promotes more microorganisms to attach to the filter medium. After the microorganisms attach to the filter medium, they will gradually form a biofilm. The biofilm is a complex structure composed of microbial communities and the sticky substances they secrete. This structure is stable and efficient, and can continuously capture and degrade pollutants in the water. The support frame 2 is fixed by buckles or bolts for easy disassembly and replacement. After the equipment is started, the surface fan pushes the equipment to perform a circular motion, and the bubbles generated by the aeration disk increase the oxygen content in the water. The underwater stirring plate realizes water layer exchange, and the sludge brought up is collected by the sludge collection bucket 4 into the collection box 5. The lifting rod 6 is regularly pulled upward to clean the collection box 5 to ensure the normal operation of the equipment.
