Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment equipment, and in particular to a solar-powered aeration and oxygenation device and system. Background Art

[0002] Solar powered aeration and oxygenation device is a device that uses solar energy as its main energy source. When sunlight shines on the solar photovoltaic panels, the panels convert light energy into electrical energy and store it in batteries. Subsequently, the microcomputer control system controls the operation of the aeration system according to the set parameters and real-time monitoring data. The aeration system evenly injects air into the water of the sewage pool, thereby increasing the dissolved oxygen content in the water.

[0003] Existing aeration systems use aeration pipes installed at the bottom of the pool for aeration. However, when aeration stops, the deposited activated sludge often quickly covers the aeration pipes, especially the aeration holes, causing blockage and seriously affecting the effective diffusion of the gas. This phenomenon delays the establishment of an aerobic environment and forces the aeration system to go through a slow startup period. During this period, a large amount of aeration gas is ineffectively consumed and fails to immediately participate in the oxidation reaction, resulting in low energy utilization and a double waste of time and resources. Based on this, the present invention purposely provides a solar-powered aeration and oxygenation device and system that can avoid the ineffective consumption of gas by deposited sludge during restart after aeration stops, and ensure that the gas and sewage undergo oxidation reaction in the initial stage of aeration. Summary of the Invention

The sleeve is driven to rotate by a ratchet assembly. When the ratchet assembly drives the sleeve to rotate so that the openings are aligned with the aeration holes, the gas in the aeration pipe enters the water body through the aeration holes and the openings in turn.

When the vertical pipe rotates clockwise, the first gear rotates synchronously clockwise. At this time, the first gear drives the sleeve to rotate through the ratchet assembly. When the vertical pipe rotates counterclockwise, the first gear rotates synchronously counterclockwise. At this time, the sleeve is stationary.

[0014] As a further solution of the present invention: a waterproof cylinder is fixedly installed on the vertical pipe, the waterproof cylinder is in contact with the bottom plate of the sewage pool, the opening and closing assembly, the ratchet assembly and the transmission assembly are all located in the waterproof cylinder, and the aeration pipe, sleeve and rotating rod all pass through the waterproof cylinder.

[0015] As a further solution of the present invention: the air supply component includes a central box and an air storage box. The central box is fixedly installed on the outer wall of the sewage pool, and its air outlet is connected to the air inlet of the exhaust fan.

[0018] Beneficial effects of the present invention:

[0019] 1. In the present invention, by providing a rotatable standpipe and an aeration tube arranged perpendicular to the axis of the standpipe, and by arranging aeration holes on the aeration tube, rotary aeration can be achieved. A sleeve is arranged on the aeration tube, and the rotation of the sleeve can control the opening and closing of the aeration holes. When the aeration holes are closed, the standpipe can drive the aeration tube to rotate to stir the deposited activated sludge before aeration, causing it to float into the water body. Then, when the aeration holes are opened by rotating the sleeve, the water body is now stirred, the sludge floats in the water body, and the aeration holes are not blocked by the sludge. The gas immediately participates in the oxidation reaction when it is injected into the water body, greatly improving energy utilization.

[0020] 2. In the present invention, after aeration begins, the driving source drives the standpipe to rotate counterclockwise again. When the standpipe rotates counterclockwise, the opening and closing assembly does not drive the sleeve to rotate through the ratchet assembly, thereby ensuring that the aeration holes are always in the open state. At the same time, the aeration pipe also rotates synchronously with the standpipe. At this time, the aeration holes rotate to inject gas into the water body, thereby performing stirring and aeration synchronously, further improving the efficiency of sewage treatment.

[0021] 3. In the present invention, when the aeration holes and the openings are aligned, aeration is in progress, and the gas enters the water body through the aeration holes and the openings. At this time, the transmission assembly drives the rotating rod to rotate, thereby breaking up and stirring the surging gas, and cutting large bubbles into smaller bubbles, thereby improving the oxygen transfer efficiency, enhancing the stirring effect, reducing sludge deposition, and improving the sewage treatment efficiency.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] See also Figures 1-12 As shown, the present invention is a solar powered aeration and oxygenation device, comprising:

[0038] A sewage tank 1 has an exhaust fan 2 fixedly mounted on its outer wall, the air inlet of the exhaust fan 2 is connected to the air supply component 3, and the air outlet is connected to the air pipe 4, which extends to the bottom of the sewage tank 1;

[0039] A standpipe 5 is rotatably mounted on the bottom plate of the sewage tank 1 and is driven to rotate by a driving source. The air inlet end of the standpipe 5 penetrates the sewage tank 1 and extends into the air delivery pipe 4. The connection between the air inlet end and the air delivery pipe 4 is dynamically sealed. The standpipe 5 is connected to an aeration pipe 6. The aeration pipe 6 has a plurality of equally spaced aeration holes 601, and its axis is perpendicular to the axis of the standpipe 5. The standpipe 5 is provided with an opening and closing assembly 8.

[0040] The sleeve 7 is rotatably mounted on the outer wall of the aeration pipe 6 and is provided with a plurality of openings 701 arranged at equal intervals. The plurality of openings 701 correspond one-to-one to the plurality of aeration holes 601. The sleeve 7 is driven to rotate by the ratchet assembly 9. When the ratchet assembly 9 drives the sleeve 7 to rotate so that the openings 701 are aligned with the aeration holes 601, the gas in the aeration pipe 6 enters the water body through the aeration holes 601 and the openings 701 in turn. When the ratchet assembly 9 drives the sleeve 7 to rotate so that the openings 701 are misaligned with the aeration holes 601, the sleeve 7 blocks the aeration holes 601. When the driving source drives the riser 5 to rotate clockwise, the opening and closing assembly 8 drives the sleeve 7 to rotate through the ratchet assembly 9. When the driving source drives the riser 5 to rotate counterclockwise, the sleeve 7 is stationary.

[0041] In one case of this embodiment, the driving source can be a motor-driven pulley assembly, a motor-driven gear rack assembly and other components, and other mechanisms that can achieve rotational motion can also be selected. This embodiment does not make specific limitations here. The dynamic seal is suitable for sealing shaft-type rotating components.

[0042] The working principle of the present invention is as follows: when aeration is required, considering that the activated sludge is deposited on the bottom of the sewage pool 1 before aeration, and the sludge accumulates and covers the aeration pipe 6, before aeration, the vertical pipe 5 is first driven by the driving source to rotate counterclockwise. At this time, the vertical pipe 5 will drive the aeration pipe 6 to rotate counterclockwise synchronously, thereby stirring the deposited activated sludge. After a period of stirring, the activated sludge is fully dispersed into the water body. At this time, the driving source drives the vertical pipe 5 to rotate clockwise. At this time, the opening and closing component 8 will drive the sleeve 7 to rotate through the ratchet component 9, and rotate the sleeve 7 until the opening 701 is aligned with the aeration hole 601. This process is as follows Figure 10 to Figure 9 As shown, the exhaust fan 2 can be turned on at this time. The exhaust fan 2 pumps the gas into the gas pipe 4 through the gas supply component 3, and then transports the gas to the standpipe 5 through the gas pipe 4. The gas in the standpipe 5 enters the aeration pipe 6 and is injected into the water body through the aeration holes 601 and the openings 701 to perform aeration. At this time, the water body is stirred, the sludge is floating in the water body, and the aeration holes 601 are not blocked by the sludge. The gas immediately participates in the oxidation reaction when injected into the water body, greatly improving the energy utilization rate.

[0043] After aeration begins, the driving source drives the standpipe 5 to rotate counterclockwise again. When the standpipe 5 rotates counterclockwise, the opening and closing assembly 8 does not drive the sleeve 7 to rotate through the ratchet assembly 9, thereby ensuring that the aeration hole 601 is always in the open state. At the same time, the aeration pipe 6 also rotates synchronously with the standpipe 5. At this time, the aeration hole 601 rotates to inject gas into the water body, thereby performing stirring and aeration synchronously, further improving the efficiency of sewage treatment.

[0044] After aeration is completed, the driving source drives the riser 5 to rotate clockwise again, causing the sleeve 7 to rotate and block the aeration hole 601, thereby avoiding sludge deposition and blocking the aeration hole 601 during the aeration stop stage, ensuring that when aeration starts next time, there is no sludge blocking the gas from entering the water body when the aeration hole 601 is opened, thereby ensuring the efficiency of the initial stage of aeration.

[0045] like Figure 3-Figure 12 As shown, as a preferred embodiment of the present invention, the opening and closing component 8 includes a vertical cylinder 801, a tooth block 802 and a first gear 803. The vertical cylinder 801 is sleeved on the vertical pipe 5, and the vertical cylinder 801 is fixedly connected to the bottom plate of the sewage tank 1. Multiple tooth blocks 802 are fixedly installed on the top of the vertical cylinder 801, and multiple tooth blocks 802 are arranged circumferentially. The first gear 803 is sleeved on the aeration pipe 6, meshed with the tooth block 802, and connected to the ratchet assembly 9. When the vertical pipe 5 rotates clockwise, the first gear 803 rotates clockwise synchronously. At this time, the first gear 803 drives the sleeve 7 to rotate through the ratchet assembly 9. When the vertical pipe 5 rotates counterclockwise, the first gear 803 rotates counterclockwise synchronously. At this time, the sleeve 7 is stationary.

[0046] In practical application, if Figure 5 As shown in the figure, the riser 5 is driven by the driving source to rotate clockwise. When the riser 5 drives the aeration pipe 6 to rotate synchronously, the first gear 803 provided on the aeration pipe 6 rotates clockwise under the action of the tooth block 802. The clockwise rotation of the first gear 803 drives the sleeve 7 to rotate through the ratchet assembly 9, thereby controlling the alignment of the opening 701 with the aeration hole 601, or controlling the sleeve 7 to rotate after the aeration is completed so that the opening 701 is misaligned with the aeration hole 601 to avoid sludge clogging the aeration hole 601. In this case, the sludge will clog the opening 701, and before the aeration work is performed, the driving source controls the riser 5 to rotate clockwise. When the tube 5 rotates counterclockwise, the aeration tube 6 also rotates counterclockwise, thereby stirring the sludge and causing it to float into the water body. The sludge in the opening 701 also floats out with the water flow, and the counterclockwise rotation of the vertical tube 5 drives the first gear 803 to rotate counterclockwise. The counterclockwise rotation of the first gear 803 does not drive the sleeve 7 to rotate through the ratchet assembly 9, which means that the sleeve 7 is stationary on the aeration tube 6. The opening 701 and the aeration hole 601 may be misaligned or aligned. When the two are aligned, the rotary aeration process is performed.

[0047] like Figure 3-Figure 12As shown, as a preferred embodiment of the present invention, the ratchet assembly 9 includes an outer wheel 901, an inner wheel 902, an inner ratchet 903 and a pawl 904. The outer wheel 901 and the inner wheel 902 are both located between the first gear 803 and the aeration tube 6. The outer wheel 901 is sleeved on the inner wheel 902 and is coaxially fixed with the first gear 803. One side of the inner wheel 902 is fixed to the sleeve 7. The inner ratchet 903 is opened on the inner wall of the outer wheel 901. Multiple pawls 904 are rotatably mounted on the inner wheel 902. When the first gear 803 rotates clockwise, the inner wheel 902 engages with the pawl 904. When the first gear 803 rotates counterclockwise, the inner wheel 902 slides with the pawl 904.

[0048] In practical application, if Figure 6 As shown in the example, when the first gear 803 rotates clockwise, it drives the outer wheel 901 to rotate synchronously, and the inner wheel 902 is engaged with the pawl 904, so the outer wheel 901 drives the inner wheel 902 to rotate synchronously, and the inner wheel 902 drives the sleeve 7 to rotate, as shown in FIG. Figure 9-10 The rotation of the middle sleeve 7 is the process of controlling the opening and closing of the aeration hole 601. When the first gear 803 rotates counterclockwise, the inner wheel 902 and the ratchet 904 slide together. At this time, the outer wheel 901 cannot drive the inner wheel 902 to rotate. Therefore, the sleeve 7 will always maintain a posture on the aeration pipe 6, and the driving source drives the standpipe 5 to rotate in different directions to control the clockwise and counterclockwise states of the first gear 803. That is, before the aeration starts, the standpipe 5 is controlled to rotate counterclockwise all the time, so that the first gear 803 can rotate counterclockwise all the time. At this time, the standpipe 5 drives the aeration pipe 6 and the sleeve 7 to rotate counterclockwise all the time, thereby stirring the activated sludge deposited at the bottom. Figure 10 As shown, the sludge deposited at the opening 701 is dispersed by the water flow. When the sludge is fully suspended in the water body, the driving source controls the riser 5 to rotate rapidly clockwise, causing the first gear 803 to rotate clockwise, thereby driving the sleeve 7 to rotate so that the opening 701 and the aeration hole 601 are aligned. At this time, the aeration operation can be started. Subsequently, the driving source controls the riser 5 to rotate counterclockwise again, so that rotary aeration is performed in the water body. At this time, the deposited sludge has been dispersed in the water and will not block the gas from entering the water for reaction.

[0049] like Figure 4-Figure 12 As shown, as a preferred embodiment of the present invention, a bracket 602 is fixedly installed at one end of the aeration pipe 6 away from the vertical pipe 5, a rotating rod 10 is rotatably installed on the bracket 602, and a plurality of stirring blades 11 arranged at equal intervals are fixedly installed on the rotating rod 10, each stirring blade 11 corresponds to an aeration hole 601, and the rotating rod 10 is driven to rotate by a transmission assembly 12.

[0050] In practical application, if Figure 4 As shown in the example, when the aeration hole 601 and the opening 701 are aligned, aeration is in progress, and the gas enters the water body through the aeration hole 601 and the opening 701. At this time, the transmission assembly 12 drives the rotating rod 10 to rotate, thereby breaking up and stirring the surging gas, and cutting large bubbles into smaller bubbles, thereby improving the oxygen transfer efficiency, enhancing the stirring effect, reducing sludge deposition, and improving the sewage treatment efficiency.

[0051] like Figure 4-Figure 12 As shown, as a preferred embodiment of the present invention, the transmission assembly 12 includes a collar 1201, a transmission gear 1202 and a second gear 1203, the collar 1201 is sleeved on the sleeve 7, and is coaxially fixedly connected to the outer wheel 901, the transmission gear 1202 is coaxially fixedly connected to the collar 1201, and the second gear 1203 is coaxially fixedly connected to the rotating rod 10, and is engaged with the transmission gear 1202.

[0052] In practical application, if Figure 5 Taking the example shown, since the collar 1201 is coaxially fixedly connected to the outer wheel 901, as long as the standpipe 5 rotates, the first gear 803 will definitely rotate under the action of the tooth block 802, and the first gear 803 will drive the outer wheel 901 to rotate synchronously. At this time, the collar 1201 will rotate synchronously with the outer wheel 901, and the collar 1201 will drive the transmission gear 1202 to rotate, and the transmission gear 1202 is engaged with the second gear 1203, thereby driving the second gear 1203 to rotate, and then causing the rotating rod 10 to rotate. This design can use the power of the rotation of the standpipe 5 to drive the rotating rod 10 to rotate, rationally utilizing energy, and without the need for an additional power source;

[0053] Moreover, with this driving mode, whether before or during aeration, the rotating rod 10 will rotate as long as the vertical pipe 5 rotates, thereby driving the stirring blade 11 to rotate. Specifically, before aeration, the rotation of the stirring blade 11 can be combined with the rotation of the aeration pipe 6 around the vertical pipe 5, thereby enhancing the stirring and mixing effect of the deposited sludge.

[0054] like Figures 1-12 As shown, as a preferred embodiment of the present invention, a waterproof cylinder 13 is fixedly installed on the vertical pipe 5, and the waterproof cylinder 13 is in contact with the bottom plate of the sewage pool 1. The opening and closing component 8, the ratchet component 9 and the transmission component 12 are all located in the waterproof cylinder 13, and the aeration pipe 6, the sleeve 7 and the rotating rod 10 all pass through the waterproof cylinder 13.

[0055] In actual application of this embodiment, the provision of the waterproof cylinder 13 can protect the components of the opening and closing assembly 8, the ratchet assembly 9 and the transmission assembly 12 to avoid direct contact with the deposited activated sludge, and the waterproof cylinder 13 can be dynamically sealed with the bottom plate of the sewage tank 1 to prevent water from entering the waterproof cylinder 13.

[0056] like Figure 1 As shown, as a preferred embodiment of the present invention, the air supply component 3 includes a central box 301 and an air storage box 302. The central box 301 is fixedly installed on the outer wall of the sewage pool 1, and its air outlet end is connected to the air inlet end of the exhaust fan 2. Multiple air storage boxes 302 are fixedly installed on the outer wall of the sewage pool 1, and the air outlet end of each air storage box 302 is connected to the central box 301. Multiple air storage boxes 302 are used to transport different gases to the water body in the sewage pool 1. A detection component connected to the central box 301 is provided on the outer wall of the sewage pool 1.

[0057] In actual application of this embodiment, the water body in the sewage pool 1 is detected according to the detection component. According to the detection result, the concentration box 301 can determine the specific type of gas required, control the opening of the gas storage box 302 that conveys the corresponding gas, and convey the corresponding gas to the concentration box 301. The exhaust fan 2 will convey the gas in the concentration box 301 to the gas pipe 4, and finally aerate the most suitable gas into the water body of the sewage pool 1, so that the water body can be treated in a targeted manner.

[0058] like Figure 1 As shown, as a preferred embodiment of the present invention, the detection component includes a detection box 14, a water pump 15 and a return pipe 16. The detection box 14 is fixedly installed on the outer wall of the sewage pool 1, and has two chambers therein. A dissolved oxygen detection component 1401 is provided in one chamber, and a pH detection component 1402 is provided in the other chamber. The dissolved oxygen detection component 1401 and the pH detection component 1402 are both connected to the central box 301. The water inlet end of the water pump 15 is connected to the sewage pool 1, and the water outlet end of the water pump 15 is connected to the two chambers respectively through the first water pipe 1501 and the second water pipe 1502. The return pipe 16 connects the two chambers with the sewage pool 1.

[0059] In one case of this embodiment, the dissolved oxygen detection component 1401 includes a dissolved oxygen detector, a dissolved oxygen detection probe and other components, and the pH detection component 1402 includes a pH detector, a pH detection probe and other components. It should be noted that the above components and the detection box 14 are all existing technologies, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0060] In actual application of this embodiment, the sewage in the sewage pool 1 is pumped into the two chambers of the detection box 14 by the water pump 15, and then the dissolved oxygen detection component 1401 and the pH detection component 1402 are used to detect the dissolved oxygen and pH value in the sewage respectively. The concentration of the gas to be aerated is determined according to the detected dissolved oxygen, and the pH value of the gas to be aerated is determined according to the detected pH value. This can provide a better living environment for the growth of microorganisms, effectively treat sewage, and at the same time provide different concentrations of oxygen for black and odorous water bodies, thereby increasing the dissolved oxygen content of the water body.

[0061] like Figure 1 As shown, the present invention also provides a solar-powered aeration and oxygenation system, which includes a solar-powered aeration and oxygenation device as described in any one of claims 1 to 8, and the system also includes a solar power generation panel 21, a battery 17, an inverter 18, a PC-side control component 19, a host computer 20, and a battery 17 electrically connected.

[0062] In one case of this embodiment, it should be noted that the solar panels 21, batteries 17, inverters 18, PC-side control components 19 and host computers 20 described in the present invention are prior arts, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of the present invention.

[0063] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
