Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, specifically to a device for improving the quality of black and odorous water in rivers. Background Technology

[0002] Black and odorous water bodies represent an extreme manifestation of organic pollution in the aquatic environment that exceeds its self-purification capacity. The water is noticeably black and has a foul odor. There are virtually no plankton in the water, aquatic plants are severely degraded, the food chain has been broken, the aquatic ecosystem is unbalanced, and its functions are essentially lost. Black and odorous water bodies cause significant damage to the urban ecosystem, thereby affecting the daily lives of many citizens.

[0003] Existing Chinese patent (CN221275251U) discloses an ecological treatment device for black and odorous water in rivers:

[0004] By installing a baffle inside the fixed pipe, two channels are formed between the injection ball and the inside of the fixed pipe. These channels are connected to a water pump and an aerator via a control mechanism. A lifting mechanism then lowers the injection ball into deeper water, delivering the chemical to a deeper water layer while simultaneously injecting oxygen into the water, increasing the oxygen content and improving the treatment effect. This addresses the problem of current methods where shallow injection depth leads to poor treatment of deeper water layers, affecting the efficiency of treating black and odorous river sections. However, this method still has the following drawbacks:

[0005] The inability to continuously administer chemicals during transport reduces efficiency. Furthermore, since the degree of water pollution increases with depth, the dosage of the aforementioned methods is usually fixed, making it impossible to administer the appropriate dosage to water at different depths. This results in waste of chemicals in shallow water and insufficient dosage in deep water, thus affecting the treatment of water at different depths. Utility Model Content

[0006] In order to solve the problems existing in the prior art, the purpose of this application is to provide a device for improving the quality of black and odorous water in rivers.

[0007] The present application describes a device for improving the quality of black and odorous water in rivers, which includes a hull and a fixing plate, with the fixing plate fixedly connected to the hull.

[0008] A multi-stage push rod is fixedly attached to the fixed plate. A connecting plate is fixedly attached to the telescopic end of the multi-stage push rod. A conveying pipe is fixedly attached to the connecting plate. An air bladder is fixedly attached to the conveying pipe. An air inlet pipe is provided on the air bladder. One end of the air inlet pipe passes through the conveying pipe. An elastic telescopic tube connected to the air inlet pipe is fixedly attached inside the conveying pipe. A piston is fixedly attached to the telescopic end of the elastic telescopic tube. A fixed pipe is provided on the conveying pipe. A conveying mechanism is connected to the hull. The conveying mechanism can convey the agent for treating black and odorous water into the conveying pipe.

[0009] Furthermore, it is particularly preferred that a fixing ring is fixedly connected to the disc, a ventilation channel is opened inside the fixing ring, multiple air outlet pipes are connected to the fixing ring, and a second air inlet pipe is connected to the fixing ring, the second air inlet pipe passing through the filter cartridge.

[0010] Furthermore, it is particularly preferred that the fixing tube has a sphere with multiple fine holes.

[0011] Furthermore, it is particularly preferred that the airbag be configured as an ellipse.

[0012] Furthermore, it is particularly preferred that an aeration pipe is fixedly connected to the fixed plate, the aeration pipe is equipped with multiple aeration heads, and a first telescopic hose is connected to the aeration pipe.

[0013] Furthermore, it is particularly preferred that multiple drive columns are rotatably connected to the hull, a motor is fixedly connected to the hull, the output end of the motor is fixedly connected to the drive columns, a conveyor belt is provided on the drive columns, and a collection box is provided inside the hull.

[0014] Furthermore, it is particularly preferred that the conveying mechanism includes a storage tank and an inlet pipe connected to the storage tank, a water pump connected to the inlet pipe is fixed to the hull, the outlet of the water pump is connected to a U-shaped pipe, and a second telescopic flexible hose connected to the conveying pipe is provided on the U-shaped pipe.

[0015] The advantages of the river black and odorous water quality improvement device described in this application are as follows:

[0016] By using conveyor belts to remove foreign objects such as leaves and garbage from the water, the water in the river can be purified more effectively and comprehensively, thereby improving the treatment effect of black and odorous water in the river.

[0017] The design of the fine holes allows the agent to be sprayed in a spreading manner, thereby increasing the spraying area and enabling the agent to better contact and mix with the water. This is different from spraying the agent directly through a fixed pipe, where the sprayed agent is difficult to spread out, resulting in poor contact between the agent and the water and affecting the treatment of the water.

[0018] Through the coordination of the aforementioned airbag, air inlet pipe, elastic telescopic tube, and piston, as the delivery pipe gradually penetrates deeper into the water, the piston moves downward within the delivery pipe, gradually opening the seal on the liquid inlet of the fixed pipe. This causes the dosage of the pesticide sprayed through the fine orifice to gradually increase, thereby enhancing the treatment of water at different depths. This avoids the problem that when spraying pesticides into water, the degree of pollution in the water increases with depth, and if the dosage of pesticide sprayed through the fine orifice is fixed, it would lead to pesticide waste in shallow water areas and insufficient dosage in deep water areas, thus affecting the treatment of water at different depths.

[0019] Meanwhile, by gradually increasing the dosage of the sprayed medicine with the depth of the water, the existing technology, which usually involves spraying the medicine into the water after the delivery pipe has entered the corresponding depth, can avoid the problem of the fixed dosage of the medicine sprayed in the existing technology, which cannot treat water at different depths and thus reduces the treatment effect of the water.

Detailed Implementation

[0026] Example 1

[0027] A device for improving the quality of black and odorous water in rivers, such as Figures 1-5 As shown, it includes a hull 1 and a fixing plate 2, with the fixing plate 2 fixedly attached to the hull 1.

[0028] A multi-stage push rod 3 is fixedly connected to the fixed plate 2. A connecting plate 4 is fixedly connected to the telescopic end of the multi-stage push rod 3. A conveying pipe 5 is fixedly connected to the connecting plate 4. An air bladder 6 is fixedly connected to the conveying pipe 5. An air inlet pipe 7 is provided on the air bladder 6. One end of the air inlet pipe 7 passes through the conveying pipe 5. An elastic telescopic pipe 8 connected to the air inlet pipe 7 is fixedly connected inside the conveying pipe 5. A piston 9 is fixedly connected to the telescopic end of the elastic telescopic pipe 8. A fixed pipe (0) is provided on the conveying pipe 5. A conveying mechanism is connected to the hull 1. The conveying mechanism can convey the agent for treating black and odorous water into the conveying pipe 5.

[0029] The fixed tube 10 is provided with a ball 11, and the ball 11 has multiple fine holes 11a.

[0030] Airbag 6 is designed as an ellipse.

[0031] An aeration pipe 12 is fixedly connected to the fixed plate 2. The aeration pipe 12 is equipped with multiple aeration heads 13. A first telescopic hose 14 is connected to the aeration pipe 12.

[0032] Multiple transmission columns 21 are rotatably connected to the hull 1. A motor 22 is fixedly connected to the hull 1. The output end of the motor 22 is fixedly connected to the transmission column 21. A conveyor belt 23 is provided on the transmission column 21. A collection box 24 is provided inside the hull 1.

[0033] The conveying mechanism includes a storage tank 31 and an inlet pipe 32 connected to the storage tank 31. A water pump 33 connected to the inlet pipe 32 is fixedly connected to the hull 1. The outlet end of the water pump 33 is connected to a U-shaped pipe 34. A second telescopic hose 35 connected to the conveying pipe 5 is provided on the U-shaped pipe 34.

[0034] When using the black and odorous water quality improvement device for this river, firstly, the first telescopic hose 14 is connected to the external aerator, the storage tank 31 is filled with chemicals, and the hull 1 is located on the river. At this time, the airbag 6 is in a state of about to come into contact with the water in the river.

[0035] Next, when it is necessary to treat the black and odorous water in the river, based on the view from front to back, the motor 22 is controlled to rotate the transmission column 21 counterclockwise. The transmission column 21 moves the transmission conveyor belt 23. During this process, since part of the conveyor belt 23 is located in the water, the conveyor belt 23 will come into contact with foreign objects such as leaves and garbage in the water and carry them out of the water. The garbage carried out will fall into the collection box 24 as the conveyor belt 23 moves. In this way, by cleaning the foreign objects such as leaves and garbage in the water through the conveyor belt 23, the water in the river can be better and more thoroughly purified, thereby improving the treatment effect of the black and odorous water in the river.

[0036] To explain, when it is necessary to process the garbage in the collection box 24, the staff first pulls the collection box 24 away from the transmission column 21 by using the auxiliary handle, so that the transmission column 21 will not limit the collection box 24 when it is lifted. Then the staff uses the auxiliary handle to lift the collection box 24 out of the hull 1, and then the garbage in the collection box 24 can be cleaned.

[0037] Meanwhile, during the operation of the conveyor belt 23, the multi-stage push rod 3 is controlled to move the connecting plate 4 downwards. The aeration pipe 12, aeration head 13, and conveying pipe 5, along with their connected parts, will move downwards synchronously with the connecting plate 4. The first telescopic hose 14 and the second telescopic hose 35 are stretched, and the connecting plate 4 and its connected parts will then enter the water body. During this process, the water pump 33 is simultaneously controlled to extract the agent from the storage tank 31 through the inlet pipe 32, and then pump it sequentially into the U-shaped pipe 34 and the second telescopic hose 35. At this time, due to the piston 9 blocking the agent, the agent... The agent enters the corresponding sphere 11 through the fixed tube 10 above and is sprayed out through the fine hole 11a. The sprayed agent will come into contact with the water to treat the pollutants in the water, thereby achieving the effect of improving the water quality. At the same time, the design of the fine hole 11a makes the agent spray in a spreading state, thereby increasing the spraying area and allowing the agent to better contact and mix with the water. This is different from if the agent is sprayed directly through the fixed tube 10, the sprayed agent is difficult to achieve a spreading effect, resulting in poor contact between the agent and the water and affecting the treatment of the water.

[0038] Meanwhile, since the airbag 6 is designed as an ellipse, the resistance of the airbag 6 when entering the water can be reduced. Then, as the connecting plate 4 and the parts connected to it gradually go deeper into the water, the water pressure on the airbag 6 will gradually increase. During this process, the water pressure will exert a squeezing force on the airbag 6, causing the airbag 6 to be gradually flattened. The air in the airbag 6 will be squeezed into the air inlet pipe 7 and enter the elastic telescopic tube 8 through the air inlet pipe 7. Then the air will force the telescopic end of the elastic telescopic tube 8 to extend. The piston 9 will move down as the telescopic end of the elastic telescopic tube 8 extends, so that the liquid inlet of the upper fixed tube 10 is fully opened, that is, the piston 9 moves away from the liquid inlet of the upper fixed tube 10. Then more medicine will enter the corresponding ball 11 through the upper fixed tube 10 and be sprayed out through the fine hole 11a. At this time, the airbag 6 is located in the middle of the water.

[0039] Then, as the connecting plate 4 continues to move downward, the water pressure will further compress the airbag 6, and the air will further force the telescopic end of the elastic telescopic tube 8 to extend. The piston 9 continues to move downward, and the liquid inlet of the lower fixed tube 10 will be blocked by the piston 9. At this time, the airbag 6 is located in the lower part of the water body. Then, when the airbag 6 is located at the bottom of the water body, as the water pressure compresses the airbag 6, the air will further force the telescopic end of the elastic telescopic tube 8 to extend. The piston 9 continues to move downward, and the liquid inlet of the lower fixed tube 10 will be fully opened.

[0040] Thus, through the cooperation of the airbag 6, air inlet pipe 7, elastic telescopic pipe 8, and piston 9, as the delivery pipe 5 gradually penetrates deeper into the water, the piston 9 moves downward within the delivery pipe 5, thereby gradually opening the seal of the inlet of the fixed pipe 10. This causes the dosage of the medicine sprayed from the fine orifice 11a to gradually increase, thereby enhancing the treatment of water bodies at different depths. This avoids the problem that when spraying medicine into water bodies, the degree of pollution in the water body increases with depth, and if the dosage of medicine sprayed from the fine orifice 11a is fixed, it will lead to waste of medicine in shallow water areas and insufficient medicine in deep water areas, thus affecting the treatment of water bodies at different depths.

[0041] Meanwhile, by gradually increasing the dosage of the sprayed drug as the water depth increases through the method described above 11a, the existing technology can avoid the situation where the agent is sprayed into the water after the delivery pipe 5 has entered the corresponding depth. This method results in a fixed dosage of the sprayed drug, which makes it impossible to treat water at different depths and thus reduces the treatment effect of the water.

[0042] Meanwhile, during the water treatment process, the external aerator is simultaneously controlled to deliver air to the aeration pipe 12 through the first telescopic hose 14. The air is then sheared, pulverized, and emulsified through the aeration head 13 and introduced into the water to fully aerate it, remove organic matter, eliminate water stratification, and reduce biochemical oxygen demand and chemical oxygen demand. This achieves good phosphorus and nitrogen removal effects, effectively prevents non-flowing water from rotting and becoming smelly, eliminates black and smelly conditions, and further improves the water treatment effect.
