Description

Technical Field

[0001] The utility model relates to the field of sediment improvement equipment structures, and particularly relates to a water quality improvement and sediment improvement equipment for river basins. Background Technique

[0002] Organic particulate matters such as rotting garbage, fish feces, fertilizers, dead algae, and wastewater discharge in water bodies sink to the bottom, and together with dead organisms after fermentation and decomposition, they mix with sediment at the bottom to form sediment. A certain thickness of sediment can play a role in supplying fertilizer, retaining fertilizer, and regulating and buffering sudden changes in water quality. However, too thick sediment or deteriorated sediment quality can cause serious harm to water quality and aquatic plants and animals. When the concentration of organic substances in the sediment is too high, it is conducive to the formation of anaerobic conditions at the bottom, leading to the production of toxic metabolites by microorganisms, and the increase of harmful substances such as ammonia nitrogen and nitrite, which further exacerbates the blackening and stinking of the sediment and the deterioration of water quality. The massive reproduction of parasites and germs requires the cleaning of the sediment to improve the water quality of the water body.

[0003] In the prior art, when cleaning the sediment at the bottom of the water body, most of the dredging projects adopted are wet dredging or dry-wet dredging, but their targets are all the sediment, and they will not improve the water quality of the existing water body. Wet dredging stirs the sediment through equipment, uses a pump to pump up the muddy water mixture, and then conducts post-treatment on it. Dry-wet dredging is more thorough, but it requires dry-river operation. For large water bodies, the water pumped up by wet dredging is generally transported to a fixed place for treatment, which requires long water pipes and other equipment, and at the same time, a high-power sewage pump needs to be equipped for transportation, with a large amount of work and certain inconvenience in use. Therefore, we disclose a water quality improvement and sediment improvement equipment for river basins to meet people's needs. Content of the Utility Model

[0004] The purpose of this application is to provide a water quality improvement and sediment improvement equipment for river basins to solve the problems mentioned in the above background technique, that is, for large water bodies, the water pumped up is generally transported to a fixed place for treatment, which requires long water pipes and other equipment, and at the same time, a high-power sewage pump needs to be equipped for transportation, with a large amount of work and certain inconvenience in use.

[0005] To achieve the above object, the present application provides the following technical solution: A device for improving water quality and sediment in a basin, including a hull.

One side of the ozone-coupled micro-nano control tank is connected to the extension pipe through a connection unit.

[0008] Preferably, the connection unit includes a communicating pipe. A sliding sleeve is installed on the top side of the ozone-coupled micro-nano control tank. The communicating pipe is slidably installed on the sliding sleeve. One end of the communicating pipe is connected to the extension pipe and the other end is connected to the ozone-coupled micro-nano control tank.

[0010] Preferably, a sealing ring is sleeved on the outer side wall near the top end of the receiving box. One side of the sealing ring is matched with the inner side wall of the independent chamber.

[0011] Preferably, a decorative cover is installed on the top side of the hull.

[0012] Preferably, while the flocculation sedimentation tank separates mud from water, it transfers phosphates in the water to the sludge. The ozone-coupled micro-nano control tank uses ozone to oxidize and remove organic matters in the water, such as ammonia nitrogen and COD, so as to achieve the purpose of improving bottom mud and enhancing water quality.

The discharged water enters the ozone-coupled micro-nano control tank through the connection unit. Through the setting of the sealing ring, it is convenient to increase the sealing performance between the receiving box and the tank body and prevent sludge from entering the bottom side of the receiving box.

[0023] Embodiment: Refer to Figures 1-4 A water quality improvement and sediment improvement device for a river basin as shown, including a hull 1. A sewage pump 5, a flocculation sedimentation tank 6 and an ozone coupled micro-nano control tank 7 are installed in the cabin of the hull 1. The flocculation sedimentation tank 6 is located in the middle position. The water inlet end of the sewage pump 5 is connected with a water inlet pipe 2. A partition board 16 is installed in the middle of the inner side of the flocculation sedimentation tank 6 to divide the tank into two independent tank bodies. Three-way pipes 8 are installed at the water outlet end of the sewage pump 5 and one side of the ozone coupled micro-nano control tank 7. The other two ends of the three-way pipes 8 are connected to one side of the two independent tank bodies and are provided with valves. A water outlet pipe 3 is installed on one side of the ozone coupled micro-nano control tank 7. Receiving boxes 10 are slidably installed in both independent tank bodies, and lifting components are installed on one side of both receiving boxes 10.

[0024] Based on the above structure, the hull 1 floats on the water surface and can move flexibly. After moving to the corresponding position, the sewage pump 5 pumps the muddy water mixture into the flocculation sedimentation tank 6 for muddy water separation. At the same time, the phosphate in the water body is transferred to the sludge and sinks into the receiving box 10. The separated water enters the ozone coupled micro-nano control tank 7 to achieve the removal of ammonia nitrogen and COD, achieving the purpose of water quality improvement. There are two independent tank bodies in the flocculation sedimentation tank 6, which are connected in turn and alternately through the three-way pipes 8, so that when one tank body is sedimenting, the sludge sedimented in the other tank body can be cleaned. The sludge sedimented in the receiving box 10 can move to the top side position of the tank body through the lifting component along with the receiving box 10, and then it is cleaned.

[0025] As Figure 4As shown in the figure, the lifting assembly includes a lead screw 15. A fixed frame 12 is installed on the top side of the flocculation sedimentation bin 6.

A fixed pipe 11 is installed on one side of the receiving box 10. An internal thread is provided in the fixed pipe 11. The lead screw 15 is screwed and matched with the internal thread. The motor 13 drives the lead screw 15 to rotate. During the rotation of the lead screw 15, the fixed pipe 11 and the receiving box 10 are driven to move up and down along the inner wall of the bin, realizing the lifting function.

[0026] As Figure 4 and 3 shown in the figure, a fixed frame 22 is installed on the inner wall of one side of the receiving box 10. The fixed frame 22 is cylindrical. One end of the fixed frame 22 is communicated with the receiving box 10, and the other end is installed with an extension pipe 18.

One side of the ozone coupling micro-nano control bin 7 is connected to the extension pipe 18 through a connection unit. When the receiving box 10 moves to the top side position of the bin, there is sludge and part of the water body in the receiving box 10. At this time, the baffle 19 is slid upward, and the water body flows out through the filter screen 23 and the extension pipe 18 after being filtered, and the water in the receiving box 10 can be discharged, so as to facilitate the cleaning of the sludge. The discharged water enters the ozone coupling micro-nano control bin 7 through the connection unit.

The communicating pipe 9 slides along the sliding sleeve 21 and can be connected to the corresponding extension pipe 18, facilitating the diversion of water into the ozone coupling micro-nano control bin 7.

[0028] As Figure 4 shown in the figure, rollers 17 are installed on both sides of the receiving box 10. The rollers 17 are matched with the inner wall of the independent bin. Through the setting of the rollers 17, it is convenient to reduce the friction between the receiving box 10 and the inner wall of the bin during movement and facilitate the movement.

[0029] As Figure 4 shown in the figure, a sealing ring 20 is sleeved on the outer side wall of the receiving box 10 near the top end. One side of the sealing ring 20 is matched with the inner wall of the independent bin. Through the setting of the sealing ring 20, it is convenient to increase the sealing performance between the receiving box 10 and the bin and prevent sludge from entering the bottom side of the receiving box 10.

The decorative cover 4 can protect the equipment, and at the same time, after the installation of the decorative cover 4, the whole is presented in the form of a cruise ship, having a good landscape effect.

[0031] While the flocculation sedimentation tank 6 separates mud and water, it transfers the phosphate in the water to the sludge. The ozone-coupled micro-nano control tank 7 uses ozone to oxidize and remove organic matters in the water, such as ammonia nitrogen and COD, so as to achieve the purpose of improving the bottom mud and enhancing the water quality.

[0032] The working principle of the present utility model:

[0033] The hull 1 floats on the water surface. After moving to the corresponding position, the sewage pump 5 pumps the mud-water mixture into the flocculation sedimentation tank 6 for mud-water separation. At the same time, the phosphate in the water body is transferred to the sludge and sinks into the receiving box 10. The separated water enters the ozone-coupled micro-nano control tank 7 to achieve the removal of ammonia nitrogen and COD, so as to achieve the purpose of enhancing the water quality. There are two independent chambers in the flocculation sedimentation tank 6, which are sequentially and alternately connected through a tee pipe 8, so that when one chamber is sedimenting, the sludge sedimented in the other chamber can be cleaned. The motor 13 drives the screw rod 15 to rotate. During the rotation of the screw rod 15, the fixed pipe 11 and the receiving box 10 are driven to move up and down along the inner wall of the chamber. The sludge sedimented in the receiving box 10 moves with the receiving box 10 to the top side position of the chamber, and then it is cleaned.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
