Description

Technical fields:

[0001] This utility model relates to the field of environmental protection equipment technology, and more specifically to a river purification and oxygenation device. Background technology:

[0002] In rivers, oxygenation can increase the oxygen content of the water. This oxygen can be utilized by microorganisms, zooplankton, and benthic animals in the water, helping to accelerate the decomposition of organic matter and the dissolution of oxygen from the air, thus promoting the self-purification of the water body.

[0003] Therefore, installing oxygenation pumps in rivers can greatly improve the purification effect of rivers. However, existing booster pumps generally use impeller rotation to drive the water to rotate, so that air is mixed into the water to increase oxygenation. However, the effect is limited, and the water is easy to splash around, so the effect is not ideal.

[0004] Another method involves connecting an air intake pipe to the submersible pump, which extends above the water surface to oxygenate the water. This method avoids water splashing and ensures stable operation. However, the submersible pump's inlet only uses a filter screen to remove large particles from the water, failing to remove fine particles. This can easily damage the impeller inside the pump, reducing its lifespan. Furthermore, the air intake pipe allows air to enter directly, and harmful gases or substances in the air can mix into the water, causing pollution. Utility Model Content:

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a river purification and oxygenation device. It can filter the water it draws in, greatly reducing the particulate matter in the water and minimizing damage to the impeller in the submersible pump. At the same time, it directly introduces pure oxygen, greatly increasing the oxygen content in the river water and improving the purification effect.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A river purification and oxygenation device includes a submersible pump body, which is fixed to the wall of one side of the river and is submerged in water.

[0008] The submersible pump body has a water inlet pipe at the bottom water inlet, and a filter device is installed at the bottom of the water inlet pipe.

[0009] The bottom outlet of the submersible pump body is connected to the inlet end of a three-way connecting pipe. The upper middle part of the three-way connecting pipe has an air inlet connector that is connected to a vertical air inlet pipe. The top of the vertical air inlet pipe extends out of the water surface of the river. The outlet end of the three-way connecting pipe is connected to a check valve device.

[0010] The filtration device includes a filter housing, with an upper connecting cover fixed to the top of the filter housing. An upwardly extending connecting pipe is formed in the middle of the top surface of the upper connecting cover, which is fixedly connected to the bottom end of the water inlet pipe by bolts. The connecting pipe communicates with the water inlet pipe and the inner cavity of the filter housing. A water inlet groove is formed on the side plate of the filter housing. A filter screen is fixedly connected to the outer side wall of the side plate of the filter housing corresponding to the water inlet groove by bolts. The filter screen covers the corresponding water inlet groove. A sleeve-shaped filter element for filtering water is installed in the inner cavity of the filter housing.

[0011] The top of the vertical air inlet pipe is connected to the outlet of an electric regulating valve, and the inlet of the electric regulating valve is connected to the oxygen outlet of the pure oxygen machine through a connecting pipe.

[0012] The outstanding effect of this utility model is:

[0013] Compared with existing technologies, it can filter the water it draws in, greatly reducing the particulate matter in the water and minimizing damage to the impeller in the submersible pump body. At the same time, it can directly introduce pure oxygen, greatly increasing the oxygen content in the river water and improving the purification effect. Moreover, the direct introduction of pure oxygen will not introduce other impurities and will not pollute the water body. Attached image description:

[0017] For example, see below. Figures 1 to 3 As shown, a river purification and oxygenation device includes a submersible pump body 10, which is fixed to the wall of one side of the river and is submerged in water.

[0018] The submersible pump body 10 has a water inlet pipe 11 connected to the bottom water inlet, and a filter device 20 is installed at the bottom end of the water inlet pipe 11.

[0019] The bottom outlet of the submersible pump body 10 is connected to the inlet end of a three-way connecting pipe 12. The upper middle part of the three-way connecting pipe 12 forms an air inlet connector that is connected to a vertical air inlet pipe 13. The top of the vertical air inlet pipe 13 extends out of the water surface of the river. The outlet end of the three-way connecting pipe 12 is connected to a check valve device 30.

[0020] Furthermore, the filtration device 20 includes a filter housing 21, with an upper connecting cover 22 fixed to the top of the filter housing 21. An upwardly extending connecting pipe is formed in the middle of the top surface of the upper connecting cover 22, which is fixedly connected to the bottom end of the water inlet pipe 11 by bolts. The connecting pipe communicates with the water inlet pipe 11 and with the inner cavity of the filter housing 21. A water inlet groove is formed on the side plate of the filter housing 21. A filter screen 23 is fixedly connected to the outer side wall of the side plate of the filter housing 21 corresponding to the water inlet groove by bolts. The filter screen 23 covers the corresponding water inlet groove. A sleeve-shaped filter element 24 for filtering water is installed in the inner cavity of the filter housing 21.

[0021] Furthermore, the central through hole of the connecting pipe extends downward through the bottom surface of the upper connecting cover 22 and communicates with the inner cavity of the filter housing 21. An annular positioning part is formed in the center of the top surface of the bottom plate of the filter housing 21. The bottom of the filter element 24 is inserted into the annular positioning part, and its outer side wall is tightly attached to the inner side wall of the annular positioning part. The bottom surface of the filter element 24 is pressed against the top surface of the bottom plate of the filter housing 21, and the top surface of the filter element 24 is pressed against the bottom surface of the upper connecting cover 22. The sleeve part extending from the center of the top surface of the filter element 24 is inserted into the bottom end of the central through hole of the connecting pipe. A sealing ring is clamped between its outer side wall and the inner side wall of the bottom end of the central through hole.

[0022] With the above structure, when a large amount of debris covers the filter screen 23, the filter screen 23 can be disassembled with bolts for replacement and cleaning, and then reinstalled. The operation is relatively convenient.

[0023] When there is too much residue on the filter layer of filter element 24, the upper connecting cover 22 can be removed, and then the filter housing 21 can be removed, the filter element 24 can be removed and replaced, and then reinstalled. It is very convenient.

[0024] Furthermore, the check valve device 30 includes a sleeve-shaped main housing 31 connected to the outlet end of the three-way connecting pipe 12. A radially extending positioning annular ring 32 is formed on the inner wall of the inner end of the main housing 31. An internal thread is formed on the inner wall from the outer end to the middle of the main housing 31. An adjusting pressure plate 33 is screwed into the internal thread of the main housing 31. A protrusion is formed on the inner end face of the middle of the adjusting pressure plate 33, and a positioning rod 331 is formed in the middle of the inner end face of the protrusion. The valve plate 34 is positioned... In the main housing 31, it is located between the adjusting pressure plate 33 and the inner end of the main housing 31. An extension 341 is formed in the middle of the outer end face of the valve plate 34. The positioning rod 331 is inserted into the insertion hole formed in the middle of the outer end face of the extension 341. The outer side wall of the positioning rod 331 is close to or tightly attached to the inner side wall of the insertion hole. The inner end face of the valve plate 34 presses against the outer end face of the positioning ring 32 and covers the middle through hole of the positioning ring 32. Multiple water passage holes are formed on the adjusting pressure plate 33.

[0025] The compression spring 35 is inserted into the protrusion and the extension 341. One end of the compression spring 35 applies force to the inner end face of the adjusting pressure plate 33, and the other end applies force to the outer end face of the valve plate 34.

[0026] Furthermore, the inner end face of the valve plate 34 is formed with an annular pressing protrusion 342, and the inner end face of the annular pressing protrusion 342 presses against the outer end face of the positioning ring 32.

[0027] Furthermore, the outer end face of the adjusting pressure plate 33 is formed with an outwardly extending protrusion, and the outer end face of the protrusion is formed with an internal hexagonal adjusting recess.

[0028] In the above structure, the internal hexagon head of the internal hexagon wrench can be inserted into the internal hexagon adjustment recess and cooperate with it. By rotating the adjustment plate 33, the pressure of the clamping spring 35 can be changed, thereby changing the pressure on the valve plate 34. This requires increasing the pressure of the impact valve plate 34 to open it, so that the water can be discharged from the water passage formed on the adjustment plate 33, thus achieving the pressure regulation function.

[0029] Furthermore, the top of the vertical air inlet pipe 13 is connected to the outlet of an electric regulating valve 18, and the inlet of the electric regulating valve 18 is connected to the oxygen outlet of the oxygen purifier 19 via a connecting pipe. The oxygen purifier 19 is installed on the bank of the river, where a control box is also installed. The submersible pump body 10, the electric regulating valve 18, and the oxygen purifier 19 are all electrically connected to the control box (not shown in the attached diagram) via electrical connection cables, and are controlled and operated through the control box. Both the control box and the oxygen purifier 19 are commercially available products and will not be described in detail here.

[0030] In this embodiment, all connected pipes and connection ends are clamped with sealing gaskets, and some interconnected components are also clamped with sealing rings to improve sealing performance.

[0031] In this embodiment, the submersible pump body 10 operates, allowing river water to enter the inlet channel through the filter screen 23 of the check valve device 30, then through the filter element 24 into the pump body of the submersible pump body 10, and finally out through the outlet of the three-way connecting pipe 12. This first opens the valve plate 34, allowing the water to exit through the water passage formed on the regulating pressure plate 33. During this process, when the submersible pump body 10 is opened, the pure oxygen generator 19 also starts in conjunction with it. At the same time, the electric regulating valve 18 opens, allowing oxygen from the pure oxygen generator 19 to enter the three-way connecting pipe 12 through the vertical air inlet pipe 13. As the oxygen mixes with the water at the outlet of the three-way connecting pipe 12 and is discharged, the oxygen content of the river water is increased, improving the oxygenation effect. The increased oxygen in the river water reduces the formation of black substances such as iron sulfide, thus improving water quality and purification effect.

[0032] Among them, the electric regulating valve 18 can adjust the cross-sectional area of ​​the gas flow, thereby controlling the flow rate of pure oxygen entering the vertical air intake pipe 13.

[0033] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
