Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and more specifically, to a nano-microbial water purifier. Background Art

[0002] In order to solve the problem of low dissolved oxygen content in black and odorous water bodies, nano-aeration oxygenation technology is often used in the process of river regulation. Traditional aeration technology has defects such as high energy consumption and low oxygen utilization efficiency, and improper use during the aeration process will cause sediment suspension, resulting in secondary pollution of the water body.

[0003] Micro-nano aeration technology is a new technology that has made breakthrough progress in recent years. The generated micro-nano bubbles have the advantages of small particle size, long residence time in water, large specific surface area, good mass transfer effect, etc., and can achieve efficient and lasting reoxygenation of the water body, thereby improving the physiological activity of aerobic microorganisms in the water body, accelerating the degradation of pollutants, and promoting water purification. Therefore, it has received relatively wide attention in water environment governance and ecological restoration projects.

[0004] At present, the common micro / nano aeration equipment on the market has an insignificant effect on treating river black and odorous sewage. Therefore, how to further achieve biological filtration and improve the river regulation effect while increasing the dissolved oxygen content through the aeration equipment is the technical problem to be solved by the present invention. Summary of the Invention

[0005] A series of simplified concepts are introduced in the Summary of the Invention section, which will be further elaborated in the Detailed Description section. The Summary of the Invention section of the present invention does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0006] To at least partially solve the above problems, the present invention provides a nano-microbial water purifier, including: a material cylinder and an aeration device; a counterweight is provided at the top of the material cylinder for maintaining the material cylinder below the liquid level. A packing area is provided inside the material cylinder, and packing is filled in the packing area. The aeration device extends into the material cylinder, and a first distance is reserved between the bottom of the material cylinder and the river bottom.

[0007] Preferably, a plurality of first holes are provided on the side wall of the material cylinder.

[0008] Preferably, a partition is provided on the inner wall of the material cylinder. The partition divides the material cylinder into upper and lower parts. The upper part is the packing area, and the lower part is the liquid area. The counterweight is located at the top of the packing area, and the aeration device extends into the liquid area.

[0009] Preferably, a second hole and a filler adder are provided on the partition. The filler adder communicates with the filler area through the second hole and is connected to a filler supply source.

[0010] Preferably, the filler is a biological bactericide.

[0011] Preferably, it further includes a first pipe, a second pipe and a pipe connector. The pipe connector is located inside the counterweight. One end of the first pipe communicates with one end of the pipe connector, and the other end passes through the filler area and the partition and extends into the liquid area. The other end of the pipe connector communicates with one end of the second pipe, and the other end of the second pipe extends horizontally to the outside of the counterweight. The aeration device is connected to the first pipe.

[0012] Preferably, the central axis of the second pipe is flush with the liquid level, and a second distance is reserved between the bottom of the first pipe and the river bottom.

[0013] Preferably, the aeration device consists of a gas supply source, a third pipe and an aeration nozzle. The gas supply source is arranged on the top of the counterweight. The aeration nozzle is arranged on the outer side wall of the first pipe and is connected to the first pipe. The aeration nozzle is connected to the gas supply source through the third pipe.

[0014] Preferably, it further includes a vertical rod. The bottom of the vertical rod is fixed to the river bottom, and the top extends above the liquid level. The vertical rod and the counterweight are movably connected by a connecting rod. The extension line of the connecting rod is normal to the central axis of the second pipe.

[0015] Preferably, a flow guide plate is arranged on the outer wall of the first pipe, and a third hole is arranged on the side wall of the first pipe. Both the flow guide plate and the third hole are located in the liquid area. The third hole is located below the connection between the aeration device and the first pipe, and the central axis of the third hole passes through the surface of the flow guide plate.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] The aeration device can introduce oxygen in the air into the water, increasing the dissolved oxygen content in the water body. Since the aeration device extends into the cartridge and is connected to the first pipe, the gas will pass through the pipe connector from the first pipe and be ejected from the second pipe. During the gas flow, the liquid is sucked into the bottom of the cartridge and flows into the first pipe. The liquid in the first pipe will be pumped to the second pipe under the action of the pressure difference and ejected from the second pipe. Since it is necessary to adjust the central axis of the second pipe to be flush with the liquid level through the counterweight, the ejected water flow will impact the liquid level, thereby further aerating the water body. At the same time, the ejected water flow will push the purifier to rotate around the vertical rod in the center of the river, thereby changing the aeration position. In addition to having the basic aeration function, the present invention also has a biological filtration function. By filling the filler in the filler area, the river is biologically filtered. By rotating the ejected water flow to change the aeration position, the variable aeration position is realized. As the water flow is continuously sucked into the bottom of the cartridge, the water flow disturbance of different temperature layers above and below the water surface is also realized, and the nutrient and oxygen exchange of different water temperature layers is realized. This not only promotes the decomposition of organic matter and the growth of microorganisms in the water body, but also improves the self-purification ability of the water body.

[0018] Regarding the nano-microbial water purifier described in the present invention, other advantages, objectives and features of the present invention will be partially reflected by the following description, and will also be understood by those skilled in the art through the research and practice of the present invention.

Detailed implementation manners

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0032] It should be understood that the terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0033] As Figures 1 - 10 shown, the present invention provides a nano-microbial water purifier, including: a barrel 1 and an aeration device; a counterweight 3 is arranged at the top of the barrel 1 to keep the barrel 1 below the liquid level, a packing area 11 is arranged inside the barrel 1, packing is filled in the packing area 11, and the packing is a biological bactericide. The aeration device extends into the barrel 1, and a first distance is reserved between the bottom of the barrel 1 and the river bottom, so that liquid can enter the barrel 1 from the bottom of the barrel 1. A plurality of first holes are arranged on the side wall of the barrel 1.

[0034] The inner wall of the barrel 1 is provided with a partition 4. The partition 4 divides the barrel 1 into upper and lower parts. The upper part is the filling area 11, and the lower part is the liquid area 12. Since the barrel 1 is provided with a first hole, liquid can enter the filling area 11 and the liquid area 12, so as to achieve the effect of biological filtration in the filling area. The first hole can also physically filter the liquid entering the liquid area 12 to reduce the impurities entering the liquid area 12. The counterweight 3 is located at the top of the filling area 11, and the aeration device extends into the liquid area 12. The partition 4 is provided with a second hole and a filler adder 5. The filler adder 5 is communicated with the filling area 11 through the second hole, and the filler adder 5 is communicated with the filler supply source, so that filler can be supplemented into the filling area.

[0035] It also includes a first pipe 61, a second pipe 62 and a pipe connector 63. The second pipe 62 and the pipe connector 63 are both located inside the counterweight 3 and can be used as counterweight blocks, thereby reducing the number of counterweight blocks used on the counterweight 3. One end of the first pipe 61 is communicated with one end of the pipe connector 63, and the other end passes through the filling area 11 and the partition 4 and extends into the liquid area 12. The other end of the pipe connector 63 is communicated with one end of the second pipe 62, and the other end of the second pipe 62 extends horizontally to the outside of the counterweight 3. The aeration device is communicated with the first pipe 61, as Figure 1 shown. The central axis of the second pipe 62 is flush with the liquid level. A second distance is reserved between the bottom of the first pipe 61 and the river bottom, as Figure 3 shown. The second distance is greater than the first distance, so as to ensure that the liquid can be smoothly sucked into the first pipe 61.

[0036] It also includes a vertical rod 71. The bottom of the vertical rod 71 is fixed on the river bottom, and the top extends above the liquid level. The vertical rod 71 and the counterweight 3 are movably connected by a connecting rod 72. The extension line of the connecting rod 72 is normal to the central axis of the second pipe 62, as Figure 2 shown, so that the purifier can rotate around the vertical rod as the rotation axis.

[0037] Working principle and beneficial effects of the above technical solution: Through the design of the above structure, the aeration device can introduce oxygen in the air into the water to increase the dissolved oxygen content in the water body. Since the aeration device extends into the cartridge 1 and is connected to the first pipe 61, the gas will pass through the pipe connector 63 from the first pipe 61 and be ejected from the second pipe 62. During the gas flow, the liquid is sucked into the bottom of the cartridge 1 and flows into the first pipe 61. The liquid in the first pipe 61 will be pumped to the second pipe 62 under the action of the pressure difference and ejected from the second pipe 62. Since it is necessary to adjust the central axis of the second pipe 62 to be flush with the liquid level through the counterweight 3, the ejected water flow will impact the liquid level, thereby further aerating the water body. At the same time, the ejected water flow will push the purifier to rotate around the vertical rod 71 in the center of the river, thereby changing the aeration position. In addition to having the basic aeration function, the present invention also has a biological filtration function. By filling the filler in the filler area, the river is biologically filtered. By rotating the ejected water flow to change the aeration position, the variable aeration position is realized. As the water flow is continuously sucked into the bottom of the cartridge 1, the water flow disturbance of different temperature layers above and below the water is also realized, and the nutrient and oxygen exchange of different water temperature layers is realized. It not only promotes the decomposition of organic matter in the water body and the growth of microorganisms, but also improves the self-purification ability of the water body.

[0038] Further, the aeration device is composed of a gas supply source 21, a third pipe 22, and an aeration nozzle 23. The gas supply source 21 is arranged on the top of the counterweight 3 and serves as a counterweight. The aeration nozzle 23 is arranged on the outer side wall of the first pipe 61 and is connected to the first pipe 61. The aeration nozzle 23 is connected to the gas supply source 21 through the third pipe 22.

[0039] Further, a flow guide plate 8 is arranged on the outer wall of the first pipe 61, and a third hole 611 is arranged on the side wall of the first pipe 61. Both the flow guide plate 8 and the third hole 611 are located in the liquid area 12. The third hole 611 is located below the connection between the aeration device and the first pipe 61. The central axis of the third hole 611 passes through the surface of the flow guide plate 8. After the liquid is sucked into the first pipe 61, a part of the liquid will be ejected from the third hole 611, and the ejected water flow directly impacts the surface of the flow guide plate 8. Under the guidance of the flow guide plate 8, the water flow direction in the liquid area 12 can be made consistent.

[0040] In the foregoing embodiment, we mentioned that the filler can be supplemented into the filler area 11 through the filler adder 5. The filler is usually a biological bactericide. However, according to different usage scenarios, the purifier may need to be equipped with fillers other than biological bactericides. At this time, a single filler area 11 is difficult to meet the diverse requirements of fillers. Therefore, we further provide an implementation method to expand the filler area 11, so that the purifier can carry a variety of styles and types of fillers at the same time.

[0041] In this embodiment, a fourth hole is provided on the partition 4, and a plurality of detachable stuffing boxes 9 are arranged in the fourth hole;

[0042] When only one type of packing is needed, a detachable cover plate is arranged in the fourth hole. Usually, an internal thread is provided on the inner wall of the fourth hole, and an external thread is provided on the outer wall of the cover plate. The fourth hole and the cover plate are connected by threads;

[0043] When multiple types of packing are needed, the cover plate is removed from the fourth hole, and then the stuffing box 9 is connected to the fourth hole. If multiple stuffing boxes 9 are provided, the stuffing boxes 9 are first connected to each other vertically, and then the stuffing box 9 at the uppermost position is connected to the fourth hole, as Figure 4 shown.

[0044] The stuffing box 9 is located above the flow guide plate 8, so as to ensure that the water flow diverted by the flow guide plate 8 can flow upward from the stuffing box 9 into the packing area 11.

[0045] Furthermore, the stuffing box 9 is composed of an outer box body 91, an inner box body 92, a support plate 93 and a cover 94. The inner box body 92 is arranged in the outer box body 91, the support plate 93 is arranged in the inner box body 92, the cover 94 is detachably connected to the outer box body 91, and between two adjacent stuffing boxes 9, the top of the outer box body 91 at the lower position is detachably connected to the bottom of the outer box body 91 at the upper position, as Figure 10 shown.

[0046] Furthermore, the outer box body 91 is a cylindrical structure with an open top. An annular clamping groove 911 is provided at the outer bottom of the outer box body 91. At least three clamping members are provided at the open top of the outer box body 91. An installation space is formed between two adjacent clamping members. The clamping member is composed of a C-shaped clamping ring 912 (with a C-shaped cross-section) and a clamping plate 913. One end (the lower end of the C shape) of the C-shaped clamping ring 912 is connected to the opening of the outer box body 91, and the other end (the upper end of the C shape) is connected to the clamping plate 913, as Figure 5 shown. The clamping plate 913 is an arc-shaped plate. The radian of the clamping plate 913 is adapted to the inner groove surface of the annular clamping groove 911, and the connection between the clamping plate 913 and the C-shaped clamping ring 912 has elasticity. When the clamping plate 913 is clamped with the fourth hole, or the clamping plate 913 is clamped with the annular clamping groove 911 at the bottom of the outer box body 91 of another stuffing box 9, the clamping plate 913 always has a tendency to recover;

[0047] When the stuffing box 9 is connected to the fourth hole, the clamping plate 913 of the outer box body 91 penetrates through the fourth hole and is clamped with the fourth hole, as Figure 4 shown. At this time, the outer surface of the clamping plate 913 abuts against the inner wall of the fourth hole;

[0048] When two adjacent stuffing boxes 9 are connected, the clamping plate 913 (of the outer box body 91) located below is clamped with the annular clamping groove 911 (of the outer box body 91) located above. As shown in Figure 10 the figure, at this time, the outer surface of the clamping plate 913 abuts against the inner surface (near the outside) of the annular clamping groove 911;

[0049] A fifth hole is provided at the bottom of the outer box body 91. As shown in Figure 6 the figure, the water flow guided by the flow guide plate 8 can enter the outer box body 91 through the fifth hole.

[0050] Furthermore, the inner box body 92 is of a tubular structure. On the outer side wall of the inner box body 92, a positioning ring 921 is arranged circumferentially. The outer wall of the positioning ring 921 abuts against the inner wall of the outer box body 91. The positioning ring 921 is used to limit the inner box body 92 in the horizontal direction. At least three supporting feet 922 are arranged at the bottom of the inner box body 92. The supporting feet 922 extend from the bottom of the inner box body 92 in a direction away from the inner box body 92. The inner box body 92 is connected to the inner bottom surface of the outer box body 91 through the supporting feet 922. As shown in Figure 5 the figure, usually the bottom of the inner box body 92 is open, and an installation ring 923 extending into the inner box body 92 is provided. The supporting feet 922 are arranged on the inner wall of the installation ring 923. By arranging the supporting feet 922, a third distance can be formed between the bottom (or the bottom surface of the installation ring 923) of the inner box body 92 and the inner bottom surface of the outer box body 91, so that a water storage space is formed between the bottom of the inner box body 92 and the inner bottom surface of the outer box body 91. The water flow can enter the water storage space from the fifth hole under the guidance of the flow guide plate 8, thereby slowing down the flow rate of the water flow entering the inner box body 92.

[0051] Usually, a lapping ring 924 is arranged on the inner wall of the inner box body 92. The lapping ring 924 is located above the supporting feet 922 (and the installation ring 923). The support plate 93 is arranged on the lapping ring 924. Usually, the connection part of the lapping ring 924 and the inner box body 92 is higher than the inner opening of the lapping ring 924, so that the lapping ring 924 is in a downward inclined state. As shown in Figure 5 the figure.

[0052] A fourth distance is left between the outer side wall of the inner box body 92 and the inner side wall of the outer box body 91. At least three sixth holes 925 are arranged on the side wall of the inner box body 92. The sixth holes 925 are located above the positioning ring 921. The inner box body 92 communicates with the outer box body 91 through the sixth holes 925.

[0053] Furthermore, the top opening of the inner box body 92 is located below the top opening of the outer box body 91. When the water flow flows from bottom to top, the water flow can flow into the outer box body 91 from the top of the inner box body 92 and the sixth holes 925.

[0054] Further, the shape of the support plate 93 is adapted to the shape of the overlapping ring 924. The outer wall of the support plate 93 abuts against the inner wall of the inner box body 92, and the bottom surface of the support plate 93 abuts against the top surface of the overlapping ring 924. The edge of the support plate 93 is located above the center of the support plate 93, as Figure 5 shown, so that the support plate 93 presents a concave shape. At the same time, at least three seventh holes 931 are provided on the support plate 93, and the seventh holes 931 are located within the opening of the overlapping ring 924. By providing the seventh holes 931, water flow can enter from the water storage space into the inner box body 92. The concave shape design of the support plate 93 enables that when the packing in the inner box body 92 is too heavy and the support legs 922 are bent and deformed and can no longer provide effective support for the inner box body 92, the concave part of the support plate 93 can directly rest on the inner bottom surface of the outer box body 91.

[0055] Further, at least three C-shaped clamping platforms 941 adapted to the inner wall of the C-shaped clamping ring 912 are provided on the side wall of the cover 94. A dislocation space is formed between two adjacent C-shaped clamping platforms 941. When installing the cover 94, first place the C-shaped clamping platforms 941 in the installation space. At this time, the clamping member is located within the dislocation space, as Figure 5 and Figure 6 shown. Subsequently, rotate the cover 94 to turn the C-shaped clamping platforms 941 into the C-shaped clamping ring 912, thereby completing the connection between the cover 94 and the outer box body 91, as Figures 7 - 8 shown. After the C-shaped clamping platforms 941 are turned into the C-shaped clamping ring 912, the connection part between the clamping plate 913 and the C-shaped clamping ring 912 abuts against the top surface of the cover 94, thereby limiting the bending angle and deformation height of the clamping plate 913, and further increasing the clamping force between the outer box body 91 and the annular clamping groove 911 (or the fourth hole). At least three eighth holes 942 are provided on the cover 94 for the water flow within the outer box body 91 to flow through.

[0056] Through the above structural design, taking Figure 4 and Figure 10 as examples, the water flow is guided by the flow guide plate 8 and then enters from the lower packing box 9 below, then flows into the upper packing box 9, and finally enters the packing area 11. Thus, the purifier can be provided with multiple different packings for treating river pollution. And because the clamping connection method of the clamping plate 913 is adopted, the disassembly and assembly of the packing box 9 are more convenient. The upward flowing water flow can continuously provide an upward force for the packing box 9, reducing the risk of the packing box 9 falling due to excessive weight. And the packing box 9 can be entirely made of plastic material, thereby greatly optimizing the production cost of the packing box 9.
