Description

Technical Field

[0001] This utility model relates to the field of oxygenation equipment technology, and in particular to a filtration device for an ultra-micro nanobubble oxygenation equipment. Background Technology

[0002] Freshwater prawns are an important freshwater aquaculture species in my country. Because freshwater prawns have extremely poor tolerance to low oxygen levels and have strict requirements for water quality, oxygen deficiency in the water is a common problem throughout the entire life cycle of freshwater prawn farming. Oxygen deficiency in freshwater prawns can lead to slow production or even large-scale "pond collapse" and death, which has become a bottleneck problem restricting the increase of freshwater prawn production and the income of farmers.

[0003] Nano-aeration technology is a new generation of high-efficiency, energy-saving and environmentally friendly technology. Generally speaking, bubbles with a size of 10 to tens of micrometers that exist in water are called microbubbles, and bubbles with a size of less than hundreds of nanometers are called nanobubbles. The mixed state of bubbles existing between the two can be called micro-nano bubbles. A level lower than micro-nano bubbles is ultra-micro-nano bubbles. Ultra-micro-nano bubbles are not affected by the solubility of air in water and are not limited by external conditions such as temperature and pressure. They can stay in water for a long time and have a significant effect on increasing the dissolved oxygen in water.

[0004] Through innovative design and development of three core technologies—a highly selective permeable membrane and a remote monitoring intelligent oxygen supply control system—we have pioneered the development of an integrated ultra-micro nanobubble oxygenation and disinfection device that supplies oxygen with pure nano-level bubbles. This breakthrough overcomes three major bottlenecks: low oxygen supply efficiency, antibiotic pollution, and cumbersome aquaculture processes, thus establishing a new model for refined and green shrimp farming.

[0005] Currently, most integrated ultra-micro nano bubble oxygenation and disinfection equipment has a pre-filter to prevent impurities in the water from accumulating inside the jet aerator. However, as the usage time increases, impurities and shrimp larvae are easily adsorbed at the filter port, causing blockage at the front end of the equipment, which slows down and weakens the water flow, thus affecting the normal use of the equipment. Utility Model Content

[0006] The technical problem to be solved by this utility model is: in order to solve the problem that the pre-filter of the existing integrated ultra-micro nano bubble oxygenation and disinfection equipment is prone to clogging, this utility model provides a filter device for ultra-micro nano bubble oxygenation equipment, which has a double-layer structure and has a self-cleaning effect, avoiding the clogging caused by impurities and shrimp larvae adsorbed on the water inlet.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a filtration device for an ultra-micro nanobubble oxygenation equipment, including a shell and a flow tube. Both the shell and the flow tube are hollow cylindrical. The flow tube is rotatably installed inside the shell, and the shell and the flow tube are coaxially arranged. One end of the shell and the flow tube on the same side is the water inlet, and the other end of the shell and the flow tube on the same side is the water outlet. The cylindrical surface of the flow tube is provided with a plurality of filter holes circumferentially. One side of the shell is provided with a water inlet, and the end of the water inlet away from the shell is connected to a water pump. Thus, when the ultra-micro nanobubble oxygenation and disinfection integrated equipment is working, the water pump causes water to enter from the water inlet on the same side of the shell and the flow tube. Part of the water flows through the filter holes of the flow tube and is transported from the water inlet to the oxygenation treatment component. Part of the water carries impurities and shrimp larvae and is discharged from the water outlet. Thus, while filtering, it also has a certain cleaning ability, avoiding impurities and shrimp larvae from clogging the water inlet, and indirectly ensuring the working effect of the ultra-micro nanobubble oxygenation and disinfection integrated equipment.

[0008] Furthermore, a number of turbine blades are arranged circumferentially on the outer side of the flow pipe. The turbine blades are arranged symmetrically about the axis of the flow pipe, and grooves are formed between adjacent turbine blades. Thus, when water flows through the inlet end, the turbine blades receive the thrust of the water, thereby generating a rotational torque in the flow pipe, making the water flow inside the flow pipe spiral, so that the impurities and shrimp larvae left in the filter holes are discharged from the outlet end, thereby strengthening the cleaning effect of the flow pipe.

[0009] Furthermore, the turbine blade includes a tip chord and a root chord, the tip chord being offset outward at an angle from the root chord, and the radial width of the turbine blade gradually increasing from the inlet end of the flow pipe to the outlet end of the flow pipe; the distance between the inlet end and the outlet end is less than the distance between the inlet end and the outlet end, and the inlet end is located on one side of the turbine blade.

[0010] Furthermore, a baffle is provided on the outer side of the flow pipe near the water outlet, and the side of the baffle is dynamically sealed to the outer shell; the end face of the baffle is fixedly connected to the turbine blade.

[0011] Furthermore, most impurities and shrimp larvae are adhered to the filter holes due to water pressure because they are too light. To solve this problem, the inner wall of the flow pipe is provided with several guide plates. The guide plates are arranged in a spiral along the inner wall of the flow pipe with the axis of the flow pipe as the center line. The filter holes are set between adjacent guide plates. Thus, the spiral guide plates make the water flow inside the flow pipe turbulent, indirectly reducing the impact of water pressure on lighter impurities and shrimp larvae.

[0012] Furthermore, the radial width of the guide plate gradually increases from the inlet end of the flow pipe to the outlet end of the flow pipe, and the edge of the guide plate is smoothly rounded; thus, the guide plate makes the interior of the flow pipe generally funnel-shaped, so that the flow area at the inlet end is larger than the flow area at the outlet end, ensuring the flow rate at the inlet end.

[0013] Furthermore, the inlet end of the flow pipe is provided with an annular component, the end of which near the inlet end is recessed into the flow pipe; the end of the outer shell near the inlet end is provided with a horn tube, which surrounds the annular component and is partially located inside the annular component. There is a gap between the annular component and the horn tube, and the gap is an annular channel. As a result, some water flows into the space between the flow pipe and the outer shell, and after hitting the inner wall of the outer shell, the water flows back towards the inlet end, passes through the annular channel, and is discharged back into the flow pipe. In addition, the discharge from the annular channel makes the inlet end a low-pressure state, thereby accelerating the water flow outside the horn tube through the flow pipe.

[0014] The beneficial effects of this utility model are as follows: the filter device of the ultra-micro nano bubble oxygenation equipment of this utility model is provided with a shell and a flow pipe, and the flow pipe is rotatably installed inside the shell; when the ultra-micro nano bubble oxygenation and disinfection integrated equipment is working, the water flows in from the same side of the shell and the flow pipe. Part of the water flows through the filter holes of the flow pipe and is then transported from the inlet to the oxygenation treatment component, while part of the water carries impurities and shrimp larvae out from the outlet. Thus, while filtering, it also has a certain cleaning ability, avoiding impurities and shrimp larvae from clogging the inlet, and indirectly ensuring the working effect of the ultra-micro nano bubble oxygenation and disinfection integrated equipment.

[0015] The filter device for the ultra-micro nano bubble oxygenation equipment of this utility model has turbine blades on the outside of the flow pipe. When water flows through the inlet, the turbine blades receive the thrust of the water, thereby generating a rotational torque in the flow pipe, making the water flow inside the flow pipe spiral, so that the impurities and shrimp larvae left in the filter holes are discharged from the outlet, thereby strengthening the cleaning effect of the flow pipe.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] The bubble generating device used in the ultra-micro nano bubble oxygenation equipment of this utility model has been disclosed in the utility model with patent number 202420321895.8. The other devices and layouts are existing structures and will not be described in detail here.

[0023] Example 1: As Figures 1-3 As shown, a filtration device for an ultra-micro nanobubble oxygenation equipment includes a housing 11 and a flow tube 12. Both the housing 11 and the flow tube 12 are hollow cylindrical, with the flow tube 12 rotatably disposed inside the housing 11. The housing 11 and the flow tube 12 are coaxially arranged. One end of the housing 11 and the flow tube 12 on the same side is the water inlet, and the other end of the housing 11 and the flow tube 12 on the same side is the water outlet. The cylindrical surface of the flow tube 12 is provided with a plurality of filter holes 125 in the circumferential direction. One side of the housing 11 is provided with a water inlet 111, which is away from the housing. One end of 11 is connected to a water pump; thus, when the integrated ultra-micro nano bubble oxygenation and disinfection device is working, the water pump causes water to enter from the inlet end on the same side of the outer shell 11 and the flow pipe 12. Part of the water flows through the filter hole 125 of the flow pipe 12 and is then transported from the inlet end 111 to the oxygenation treatment component. Part of the water carries impurities and shrimp larvae out from the outlet end, thereby having a certain cleaning ability while filtering, preventing impurities and shrimp larvae from clogging the inlet end 111, and indirectly ensuring the working effect of the integrated ultra-micro nano bubble oxygenation and disinfection device.

[0025] Reference Figure 3 A number of turbine blades 122 are arranged circumferentially on the outer side of the flow pipe 12. The turbine blades 122 are arranged symmetrically about the axis of the flow pipe 12, and grooves are formed between adjacent turbine blades 122. Thus, when water flows through the inlet end 111, the turbine blades 122 receive the thrust of the water, thereby generating a rotational torque in the flow pipe 12, making the water flow inside the flow pipe 12 spiral, so that the impurities and shrimp larvae left in the filter hole 125 are discharged from the outlet end, thereby strengthening the cleaning power of the flow pipe 12.

[0026] The turbine blade 122 includes a tip chord and a root chord. The tip chord is offset outward from the root chord at an angle. The radial width of the turbine blade 122 gradually increases from the inlet end of the flow pipe 12 to the outlet end of the flow pipe 12. The distance between the inlet end 111 and the outlet end is less than the distance between the inlet end 111 and the inlet end. The inlet end 111 is located on one side of the turbine blade 122.

[0027] Reference Figure 2 , Figure 3 A baffle 121 is provided on the outer side of the flow pipe 12 near the water outlet end. The side of the baffle 121 is dynamically sealed to the outer shell 11. The end face of the baffle 121 is fixedly connected to the turbine blade 122.

[0028] Reference Figure 3 Most impurities and shrimp larvae are attached to the filter holes 125 due to water pressure because they are too light. To solve this problem, several guide plates 124 are provided on the inner wall of the flow pipe 12. The guide plates 124 are arranged in a spiral along the inner wall of the flow pipe 12 with the axis of the flow pipe 12 as the center line. The filter holes 125 are set between adjacent guide plates 124. Thus, the spiral guide plates 124 make the water flow inside the flow pipe 12 turbulent, indirectly reducing the impact of water pressure on lighter impurities and shrimp larvae.

[0029] Reference Figure 2 The inlet end of the flow pipe 12 is provided with an annular component 123, and the end of the annular component 123 near the inlet end is recessed into the flow pipe 12. The end of the outer shell 11 near the inlet end is provided with a horn tube 112, which surrounds the annular component 123 and is partially located inside the annular component 123. There is a gap between the annular component 123 and the horn tube 112, and the gap is an annular channel. As a result, some water flows into the space between the flow pipe 12 and the outer shell 11. After the water flows into the inner wall of the outer shell 11, it flows back towards the inlet end and is discharged through the annular channel, returning to the flow pipe 12. In addition, after being discharged from the annular channel, the inlet end is in a low-pressure state, which accelerates the water flow outside the horn tube 112 through the flow pipe 12.

[0030] Example 2: The difference from Example 1 is:

[0031] The radial width of the guide plate 124 gradually increases from the inlet end of the flow pipe 12 to the outlet end of the flow pipe 12, and the edge of the guide plate 124 is smoothly rounded. As a result, the guide plate 124 makes the interior of the flow pipe 12 as a whole funnel shape, so that the flow area at the inlet end is larger than the flow area at the outlet end, ensuring the flow rate at the inlet end 111.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
