Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and in particular, relates to integrated village and town sewage treatment equipment. Background Art

[0002] In the process of village and town development, the problem of sewage discharge has become increasingly prominent. Village and town sewage includes domestic sewage, such as kitchen wastewater, washing wastewater, toilet flushing sewage, etc., as well as industrial wastewater discharged by some township enterprises. The composition is complex and contains a large number of organic pollutants. If it is directly discharged without effective treatment, it will cause serious damage to the surrounding ecological environment.

[0003] To achieve efficient sewage treatment, ensuring uniform aeration is a key link. The traditional approach is to set up a large number of aeration nozzles in different directions, trying to introduce air into the sewage from multiple angles, so that the aeration area is wide and aeration dead corners are eliminated. However, this approach brings serious problems for later maintenance. Due to the different angles of the nozzles, maintenance personnel need to spend a lot of time and energy to adjust tools and viewing angles during maintenance, which not only greatly affects the efficiency of maintenance; on the other hand, if the nozzles are all set in one direction, although it is more convenient for maintenance, maintenance personnel can inspect and repair with a unified perspective and operation method, but uniform aeration cannot be achieved. There will be aeration dead corners in the sewage treatment pool, and the sewage in some areas cannot fully contact oxygen, resulting in a significant reduction in the sewage treatment effect. Therefore, how to balance aeration uniformity and nozzle maintenance convenience has become a key issue that needs to be urgently solved in the current rural sewage treatment equipment.

[0038] For the purposes, technical solutions and advantages of the embodiments of the present invention to be clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0039] Embodiment 1:

[0040] As Figures 1 to 10 shown, the integrated rural sewage treatment equipment includes a treatment tank 1 and a circulation pipe 2 vertically sliding in the treatment tank 1, and the circulation pipe 2 is connected to the aeration system.

[0041] A spraying assembly is installed on the circulation pipe 2. The spraying assembly includes a Z-axis spraying pipe 22 installed with a first spray head 221, an X-axis spraying pipe 23 installed with a third spray head 231, and a Y-axis spraying pipe 24 installed with a fourth spray head 241; the multi-axis and multi-spray head design can aerate the sewage from multiple angles at the same time, greatly broadening the aeration area, evenly distributing air to all corners of the treatment tank, avoiding aeration dead corners, providing sufficient oxygen for aerobic microorganisms, and efficiently decomposing organic pollutants.

[0042] An adjustment assembly for adjusting the angles of the X-axis spray pipe 23 and the Y-axis spray pipe 24 is also installed on the circulation pipe 2. The adjustment assembly includes a synchronous rod 3. The synchronous rod 3 is slidably arranged in a turning groove 312 opened on the side wall of the treatment tank 1 for guiding the position of the synchronous rod 3. The other end of the synchronous rod 3 is slidably installed with a rocker arm 321. The other end of the rocker arm 321 is installed with a swing arm 33, and the swing arm 33 is rotatably connected to the X-axis spray pipe 23. A friction wheel 331 for guiding the rotation of the X-axis spray pipe 23 is installed on the X-axis spray pipe 23. A push rod 342 is installed at the end of the synchronous rod 3, and a guide block 35 is installed at the end of the push rod 342. A guide inclined surface 352 for guiding the position of the Y-axis spray pipe 24 is opened on the side wall of the guide block 35. A swing rod 36 is installed at the rotation center of the Y-axis spray pipe 24, and the swing rod 36 is slidably connected to the guide inclined surface 352. This adjustment assembly can flexibly adjust the angles of the X-axis and Y-axis spray pipes according to the actual sewage treatment requirements, further optimize the aeration coverage range, and ensure that the sewage in different areas can be fully aerated and treated.

[0043] A driving assembly and a stirring assembly are also installed on the circulation pipe 2. The driving assembly is used to drive the circulation pipe 2 to move, while the stirring assembly is used to increase the dissolution amount of gas in the pool water.

[0044] As Figures 1 to 10 shown, in the specific implementation manner, a support frame 11 is installed at the bottom of the treatment tank 1. A support leg 111 is installed at the bottom of the support frame 11. The support leg 111 and the support frame 11 are integrally cast. A reinforcing rib 112 is installed at the bottom of the support leg 111, and the reinforcing rib 112 is in an X shape. The design of the support frame 11, the support leg 111 and the reinforcing rib 112 enhances the stability of the treatment tank 1, ensures that the equipment can be stably placed during long-term operation, and reduces the impact on the sewage treatment effect caused by shaking or displacement.

[0045] As Figures 1 to 10 shown, further, a water outlet pipe 12 and a water inlet pipe 13 are respectively installed on the side wall of the treatment tank 1. The water inlet pipe 13 is located below the water outlet pipe 12. A limiting rod 14 is installed at the bottom of the treatment tank 1. A limiting plate 141 is installed at the top of the limiting rod 14. The diameter of the limiting plate 141 is larger than the diameter of the limiting rod 14. A sliding seat 25 is movably inserted on the limiting rod 14, and the sliding seat 25 is installed on the side wall of the treatment tank 1. The positions of the water inlet pipe 13 and the water outlet pipe 12 are designed in line with the sewage flow law, facilitating the entry and exit of sewage. Moreover, the cooperation of the limiting rod 14 and the sliding seat 25 plays a role in limiting and guiding the sliding of the circulation pipe 2, ensuring its stable operation, and the limiting plate 141 ensures that the limiting rod 14 and the sliding seat 25 will not separate.

[0046] Example 2:

[0047] Based on Example 1, the difference from this example is that as Figures 1 to 10As shown in the figure, a connecting pipe 21 is installed on the side wall of the circulation pipe 2. An input pipe 211 is installed on the connecting pipe 21. The input pipe 211 is connected to the aeration system. The aeration system is a prior art, and its working principle will not be elaborated here. The circulation pipe 2 is also installed with a second spray head 222. The Z-axis spray pipe 22 is connected to both ends of the circulation pipe 2. The openings of the second spray head 222 and the first spray head 221 both face upward. Adding the second spray head 222 and the specific designs of the connecting pipe 21 and the input pipe 211 can further increase the aeration points and strengthen the aeration effect, providing more sufficient oxygen for the microorganisms to decompose pollutants.

[0048] As Figures 1 to 10 shown, in the specific implementation manner, a sealing ring 233 is rotatably installed at the water inlet of the X-axis spray pipe 23. A hose 232 is connected to the sealing ring 233. The end of the hose 232 is connected to the circulation pipe 2. The sealing ring 233 and the hose 232 ensure the sealing and flexibility of the water inlet of the X-axis spray pipe 23. The X-axis spray pipe 23 is located between the Z-axis spray pipe 22 and the Y-axis spray pipe 24. A friction plate 332 is installed on the side wall of the treatment tank 1. The friction plate 332 meshes with the friction wheel 331 on the X-axis spray pipe 23 rotated by 90 degrees. Through the cooperation of the friction plate 332 and the friction wheel 331, the X-axis spray pipe 23 can be further driven to rotate when the X-axis spray pipe 23 rotates, expanding the aeration range.

[0049] As Figures 1 to 10 shown, further, a communicating pipe 242 is installed at the water inlet of the Y-axis spray pipe 24. The communicating pipe 242 is connected to the circulation pipe 2. A connecting seat 362 is installed on the circulation pipe 2. The connecting seat 362 is rotatably connected to the Y-axis spray pipe 24. A torsion spring 363 is clamped at the rotation center of the Y-axis spray pipe 24 and the connecting seat 362. A swing rod 36 is rotatably connected to the connecting seat 362, and the swing rod 36 is in a bent state. A rolling ball 361 is installed at the end of the swing rod 36. The rolling ball 361 is slidably connected to the guiding inclined surface 352. When the guiding inclined surface 352 on the guiding block 35 comes into contact with the swing rod 36 at this time and can push the swing rod 36 to rotate, and the rolling ball 361 on the swing rod 36 can slide with the guiding inclined surface 352, reducing the friction force. As the swing rod 36 swings, the swing rod 36 drives the Y-axis spray pipe 24 to rotate on the connecting seat 362, and then the torsion spring 363 can be twisted. The initial state is ensured by the torsion spring 363, and finally the Y-axis spray pipe 24 rotates synchronously by 90 degrees, and then the fourth spray head 241 on the Y-axis spray pipe 24 faces the Y-axis direction.

[0050] Example 3:

[0051] Based on Example 2, the difference from this example is: As Figures 1 to 10As shown in the figure, the flipping groove 312 is an inclined groove. The end of the flipping groove 312 at the highest point is connected to the lifting groove 311, and the end of the flipping groove 312 at the lowest point is connected to the shifting groove 313. Both the lifting groove 311 and the shifting groove 313 are vertical sliding grooves. The lifting groove 311 is closer to the side wall of the flow pipe 2 than the shifting groove 313. A sliding rod 31 is slidably installed inside the flipping groove 312, and the sliding rod 31 is connected to the side wall of the synchronizing rod 3. The rocker arm 321 is rotatably connected to the Z-axis spraying pipe 22. A strip-shaped groove 322 is formed on the rocker arm 321, and a protrusion 32 is slidably installed on the strip-shaped groove 322. The diameter of the protrusion 32 is adapted to the width of the strip-shaped groove 322, and the protrusion 32 is connected to the side wall of the synchronizing rod 3. When the sliding rod 31 on the side wall of the synchronizing rod 3 slides along the flipping groove 312, the sliding rod 31 can finally slide into the shifting groove 313, thereby driving the entire synchronizing rod 3 to have a tendency to slide towards the center. The protrusion 32 on the side wall of the synchronizing rod 3 can slide in the strip-shaped groove 322 of the rocker arm 321, and at this time, the rocker arm 321 can rotate. The rocker arm 321 rotates on the surface of the Z-axis spraying pipe 22, and then the rocker arm 321 drives the swing arm 33 to swing. At this time, the swing arm 33 drives the X-axis spraying pipe 23 to rotate by 90 degrees, thereby driving the third nozzle 231 on the X-axis spraying pipe 23 to face the X-axis direction.

[0052] As Figures 1 to 10 shown, in the specific implementation manner, a fixing seat 341 is installed on the flow pipe 2, and a positioning cover 34 is installed on the fixing seat 341. The positioning cover 34 is movably penetrated by the synchronizing rod 3 and the ejector rod 342. A baffle 343 is installed at the connection of the synchronizing rod 3 and the ejector rod 342. The baffle 343 is slidably arranged in the positioning cover 34. A return spring 344 is sleeved on the ejector rod 342 on the inner side wall of the positioning cover 34. One end of the return spring 344 is on the inner wall of the positioning cover 34, and the other end of the return spring 344 is clamped on the baffle 343. A connecting plate 351 is installed at the end of the ejector rod 342, and the connecting plate 351 is connected to the guiding block 35. When the synchronizing rod 3 slides, the synchronizing rod 3 drives the baffle 343 to slide in the positioning cover 34, thereby squeezing the return spring 344 inside the positioning cover 34 by the baffle 343, which facilitates the later reset operation through the return spring 344. When the baffle 343 slides, the baffle 343 can drive the ejector rod 342 on the side wall to slide synchronously, and the ejector rod 342 can drive the guiding block 35 connected to the connecting plate 351 to slide.

[0053] As Figures 1 to 10As shown in the figure, further, the stirring assembly includes a stirring fan blade 42. The stirring fan blade 42 is installed in the cavity between a pair of Y-axis spraying pipes 24 and the circulation pipe 2. A synchronous plate 4 is rotatably installed at the bottom of the stirring fan blade 42. Both ends of the synchronous plate 4 are installed on the side wall of the circulation pipe 2. A waterproof motor 421 is installed at the bottom of the synchronous plate 4, and the output end of the waterproof motor 421 is connected to the stirring fan blade 42. The driving assembly includes a hydraulic push rod 41. The output end of the hydraulic push rod 41 is installed at the bottom of the synchronous plate 4, and the housing of the hydraulic push rod 41 is installed at the bottom of the treatment tank 1. The stirring fan blade stirs the sewage under the drive of the waterproof motor, accelerating the dissolution of gas; the hydraulic push rod drives the synchronous plate, and then drives the circulation pipe to move, which is convenient for equipment maintenance. At the same time, the aeration position is optimized, improving the sewage treatment effect.

[0054] The implementation principle of the integrated rural sewage treatment equipment of the present invention is as follows:

[0055] When in specific use, the operator can inject rural sewage into the treatment tank 1 through the water inlet pipe 13. Then the operator aerates the inside through the aeration system. The aeration system is a prior art and is not shown in the figure. And the aeration system is a prior art, and its working principle will not be elaborated here.

[0056] The gas generated by the aeration system can be output to the input pipe 211, and can be input into the connecting pipe 21 through the input pipe 211, and then transmitted into the circulation pipe 2. At this time, aeration is carried out through the first spray head 221, the second spray head 222, the third spray head 231 and the fourth spray head 241. Aeration can fill oxygen into the sewage. Aerobic microorganisms in the sewage need to consume a large amount of oxygen during the process of decomposing organic matter. Aeration can fill enough oxygen into the sewage to meet the metabolic needs of microorganisms, enabling them to grow and reproduce normally, thereby effectively decomposing organic pollutants in the sewage, such as carbohydrates, proteins, fats, etc., and converting them into harmless substances such as carbon dioxide and water.

[0057] During the aeration process, the operator starts the waterproof motor 421, and drives the stirring fan blade 42 to rotate through the waterproof motor 421. The stirring fan blade 42 can stir the sewage, enabling the gas to be fully dissolved in the water.

[0058] When the operator needs to perform maintenance on the equipment later, the operator starts the hydraulic push rod 41, and drives the synchronous plate 4 to move through the hydraulic push rod 41. At this time, the synchronous plate 4 drives the entire circulation pipe 2 to move upward, as Figure 2 shown. At this time, the entire equipment can move upward, so that it can slide above the treatment tank 1. At this time, the openings of the first spray head 221, the second spray head 222, the third spray head 231 and the fourth spray head 241 all face upward, and the stirring fan blade 42 also faces upward synchronously. At this time, it is convenient for the operator to perform maintenance operations.

[0059] When the operator performs the reset operation, taking Figure 2 as a reference, at this time, the slide bar 31 on the side wall of the synchronization rod 3 slides along the flipping groove 312. Finally, the slide bar 31 can slide into the displacement groove 313, thereby driving the entire synchronization rod 3 to have a tendency to slide towards the center. The protrusion 32 on the side wall of the synchronization rod 3 can slide in the strip-shaped groove 322 of the rocker arm 321. Then, the rocker arm 321 can rotate at this time. The rocker arm 321 rotates on the surface of the Z-axis spray pipe 22. Then, the rocker arm 321 drives the swing arm 33 to swing. At this time, the swing arm 33 drives the X-axis spray pipe 23 to rotate by ninety degrees, thereby driving the third spray head 231 on the X-axis spray pipe 23 to face the X-axis direction. At this time, the friction wheel 331 on the side wall of the X-axis spray pipe 23 moves onto the friction plate 332. As the slide bar 31 slides in the displacement groove 313, the friction wheel 331 at this time is squeezed and rotated, thereby driving the X-axis spray pipe 23 to rotate. At this time, the third spray head 231 on the surface rotates synchronously, thus increasing the spraying range.

[0060] When the synchronization rod 3 slides, the synchronization rod 3 drives the baffle 343 to slide in the positioning cover 34. Then, the baffle 343 squeezes the reset spring 344 inside the positioning cover 34, facilitating the later reset operation through the reset spring 344. When the baffle 343 slides, the baffle 343 can drive the ejector rod 342 on the side wall to slide synchronously. The ejector rod 342 can drive the guide block 35 connected to the connecting plate 351 to slide. At this time, the guide inclined surface 352 on the guide block 35 comes into contact with the swing rod 36 and can push the swing rod 36 to rotate. The rolling ball 361 on the swing rod 36 can slide with the guide inclined surface 352, reducing the frictional force. As the swing rod 36 swings, the swing rod 36 drives the Y-axis spray pipe 24 to rotate on the connecting seat 362. Then, the torsion spring 363 can be twisted. Through the torsion spring 363, the initial state is ensured. Finally, the Y-axis spray pipe 24 rotates synchronously by ninety degrees, and then the fourth spray head 241 on the Y-axis spray pipe 24 faces the Y-axis direction.

[0061] Through the Z-axis spray pipe 22, the X-axis spray pipe 23, and the Y-axis spray pipe 24, the spray heads can introduce air into the sewage from multiple angles, greatly broadening the aeration area and evenly distributing the air to every corner of the treatment tank, effectively avoiding the emergence of aeration dead zones, enabling aerobic microorganisms to efficiently decompose the organic pollutants in the sewage under the nourishment of sufficient oxygen, and maintaining the stable operation of the sewage treatment system.
