Description

Technical Field

[0001] This utility model relates to the field of river black and odorous water treatment technology, specifically to a deodorization device for treating black and odorous water bodies. Background Technology

[0002] Black and odorous water bodies refer to environmental problems caused by excessive levels of pollutants such as organic matter, nitrogen, and phosphorus, resulting in water bodies that appear black and emit a foul odor. The main causes include external pollution (such as direct discharge of domestic sewage and agricultural non-point source pollution), internal pollution (release of pollutants from bottom sediments), and reduced self-purification capacity due to insufficient water dynamics.

[0003] Methods for treating black and odorous water bodies include: 1. Physical methods: intercepting and diverting sewage, dredging, and flushing with treated water. 2. Chemical methods: oxidation and flocculation sedimentation, used for emergency treatment and in-situ remediation of bottom sediments. 3. Biological and ecological methods: microbial agents for remediation, ecological floating island technology, and artificial aeration, to enhance the self-purification capacity of the water body.

[0004] The aforementioned artificial oxygenation methods generally use aerators to increase the oxygen content in the water. Currently, aerators include surface aerators and underwater aerators. Surface aerators rotate on the water surface, generating hydraulic jumps and droplets, allowing for full contact between air and water. Underwater aerators are installed in the lower layers of the water, achieving oxygen transfer through air diffusion or mechanical agitation. Therefore, it can be seen that achieving surface or underwater aeration requires installing two different types of aeration equipment, resulting in resource waste. Utility Model Content

[0008] Preferably, the lifting mechanism includes a support, a take-up roller shaft is rotatably mounted on the top of the support, one end of the take-up roller shaft is fixedly mounted to the output end of a second servo motor, the second servo motor is fixedly mounted on the side of the support, a steel wire rope is wound around the outside of the take-up roller shaft, and the other end of the steel wire rope extends downward and is fixedly mounted to the surface of the slider.

[0009] Preferably, a sliding rod is fixedly installed on the inner side of the support and behind the wire rope, a sliding sleeve is slidably installed on the outer side of the sliding rod, a reciprocating screw is rotatably installed on the inner side of the support and in front of the wire rope, a screw sleeve is threadedly connected to the outer side of the reciprocating screw, a protective sleeve is fixedly installed between the sliding sleeve and the screw sleeve, one end of the reciprocating screw is fixedly installed to the output end of the auxiliary motor, and the auxiliary motor is fixedly installed on the side of the support.

An electronic water level sensor is fixedly installed on the back of the support frame, and the electronic water level sensor is connected to the PLC controller via signals.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a deodorization device for treating black and odorous water bodies, which has the following beneficial effects: 1. This deodorization device for treating black and odorous water bodies is installed by placing the frame upright on a pre-reserved base in the center of the river, or by placing the frame at an angle on a base on the riverbank. An electric push rod drives the push column to retract, preventing the friction pads from contacting each other, thus unlocking the slider. A second servo motor drives the winding roller to rotate and loosen the wire rope, causing the weight of the aeration equipment below to pull the slider down the frame. When the pump pipe is submerged 30-50 cm below the water surface, a first servo motor drives the shaft to rotate. This rotation causes the pump impeller and agitator to rotate synchronously. The pump impeller generates suction, drawing water in through the pump pipe and air in through the air inlet pipe. Water is then sprayed out from the drain hole, and the sprayed water is further dispersed by the rotating agitator blades, thus achieving aeration of the water surface. Repeating the above steps, and based on the water depth measured by the electronic water level sensor, the agitator blades are extended 30-50 cm from the bottom, while the top of the air inlet pipe remains above the water surface, thus achieving aeration of the deeper water layers. Alternatively, the entire aeration device can be suspended in the middle layer of the water to achieve aeration of the middle layer. This application utilizes a single aeration device to perform surface, middle, and lower layer aeration according to the water conditions, thereby increasing the oxygen content of the water and deodorizing it; thus saving aeration equipment resources. 2. This deodorization device for treating black and odorous water bodies has an aeration device at the bottom that is adjusted to a position on the water surface, in the water, or at a deep underwater location by a lifting mechanism. Then, the push column is moved outward by an electric push rod. The friction round pad and the long friction pad squeeze each other, which locks the slider in the position of the frame. This ensures that the aeration device suspended below will not slide down, thus ensuring the stable operation of the aeration device. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 An odor control device for treating black and odorous water bodies includes a frame 1, with a pre-installed mounting base in the center of the river or on the riverbank. When the frame 1 is installed on the base in the center of the river, it can be installed vertically; when the frame 1 is installed on the base on the riverbank, it can be installed at an angle. A lifting mechanism 2 is fixedly installed on the top of the frame 1, and a slider 3 is slidably installed inside the frame 1. The lifting mechanism 2 allows the slider 3 to slide up and down on the inside of the frame 1, thereby adjusting the position of the aeration device.

[0016] Please see Figure 1 , 2 3, 5 and 6, a servo motor 4 is fixedly mounted on the side of slider 3. The output end of the servo motor 4 is fixedly mounted to the input end of the gearbox 5. The output end of the gearbox 5 is detachably mounted with a shaft 7 via a coupling. The servo motor 4 first drives the gearbox 5 to rotate, and the gearbox 5 then drives the shaft 7 to rotate. The speed of rotation of the shaft 7 can be controlled by the gearbox 5.

[0017] Please see Figure 1 , 23, 5, and 6. The outer side of shaft 7 is fitted with a tube shell 6. The top of tube shell 6 is fixedly installed with the housing of gearbox 5. An air intake pipe 8 is fixedly installed on the upper right side of tube shell 6. The other end of air intake pipe 8 is threadedly connected to a muffler 9. If the water level is deep, the muffler 9 can be removed and a pipe can be threadedly connected to the top of air intake pipe 8 to increase the overall length of air intake pipe 8. Always keep air intake pipe 8 above the water surface. Finally, the muffler 9 is threadedly installed on the top of the pipe. The muffler 9 can reduce the formation of noise.

[0018] Please see Figure 1 , 2 3, 5, and 6. A water pump pipe 10 is fixedly installed on the lower left side of the casing 6. The water pump pipe 10 must always be below the water surface when in use. The other end of the water pump pipe 10 is threaded with a filter screen 11 to intercept garbage such as plastic bags and branches. A water pump casing 12 is fixedly installed at the bottom of the casing 6. A pump impeller 13 is fixedly installed on the outside of the shaft 7 and inside the water pump casing 12. A drain hole 20 is provided at the bottom of the water pump casing 12. An agitator blade 14 is detachably installed at the bottom of the shaft 7. When the shaft 7 rotates, it will cause the pump impeller 13 and the agitator blade 14 to rotate synchronously. The rotation of the pump impeller 13 will generate suction, which will then draw water into the water pump pipe 10 and air into the air inlet pipe 8. Finally, the air and water are mixed and discharged from the drain hole 20. Finally, the mixture is dispersed by the rotation of the agitator blade 14 to increase the oxygen content of the water.

[0019] Please see Figure 4 The slider 3 has two electric push rods 15 inside. A horizontal plate 16 is fixedly installed at the output end of the electric push rod 15. A push column 17 is fixedly installed on the side of the horizontal plate 16. A friction pad 18 is fixedly installed on the end face of the push column 17. A long friction pad 19 corresponding to the friction pad 18 is fixedly installed on the inner wall of the frame 1. The rolling wheel 31 is set at a 90-degree angle to the push column 17. The electric push rod 15 drives the push column 17 to retract, and the rolling wheel 31 on the outer wall of the slider 3 separates the friction pad 18 and the long friction pad 19, allowing the slider 3 to slide in the frame 1. Conversely, the electric push rod 15 drives the push column 17 to extend, and the friction pad 18 and the long friction pad 19 press against each other, locking the slider 3 in the frame 1. The sliding of the slider 3 is assisted by the rolling wheel 31 to reduce sliding resistance.

[0020] Please see Figure 7The lifting mechanism 2 includes a support 21, with a take-up roller 22 rotatably mounted on the top of the support 21. One end of the take-up roller 22 is fixedly mounted to the output end of a servo motor 23, which is fixedly mounted on the side of the support 21. A steel wire rope 24 is wound around the outside of the take-up roller 22, and the other end of the steel wire rope 24 extends downward and is fixedly mounted to the surface of the slider 3. The take-up roller 22 can be rotated by the servo motor 23, and the rotation of the take-up roller 22 can loosen or wind up the steel wire rope 24, thereby controlling the position of the aeration device.

[0021] Please see Figure 7 A slide rod 25 is fixedly installed inside the support 21 and behind the wire rope 24. A sliding sleeve 26 is slidably installed on the outside of the slide rod 25. A reciprocating screw 27 is rotatably installed inside the support 21 and in front of the wire rope 24. A screw sleeve 28 is threadedly connected to the outside of the reciprocating screw 27. A protective sleeve 29 is fixedly installed between the sliding sleeve 26 and the screw sleeve 28. One end of the reciprocating screw 27 is fixedly installed to the output end of the auxiliary motor 30, which is fixedly installed on the side of the support 21. When the wire rope 24 is wound or unwound, the auxiliary motor 30 drives the reciprocating screw 27 to rotate, which in turn drives the screw sleeve 28 to move back and forth, thereby allowing the wire rope 24 to be laid out in an orderly manner and reducing the tangling of the wire rope 24.

[0022] Please see Figure 7 Servo motor 4, electric push rod 15, servo motor 23, and auxiliary motor 30 are all connected to the PLC controller. An electronic water level sensor is fixedly installed on the back of the support frame 1, and the electronic water level sensor is also connected to the PLC controller. The electronic water level sensor is used to detect water depth, facilitating position control of the aeration equipment. The aforementioned servo motor 4, electric push rod 15, servo motor 23, auxiliary motor 30, PLC controller, and electronic water level sensor are all references to existing technologies, and will not be described in detail in this application. When using them, the preferred option can be selected provided that the driving conditions are met.

[0023] Working principle: When in use, the stand 1 is placed upright on the reserved base in the center of the river, or the stand 1 is placed at an angle on the base on the bank of the river. The push column 17 is retracted by the electric push rod 15. The friction round pad 18 and the long friction pad 19 do not contact each other, and the position of the slider 3 will be unlocked. The servo motor 23 drives the take-up roller 22 to rotate and loosens the wire rope 24. The weight of the aeration equipment below will cause the slider 3 to slide down the frame 1. When the water pump pipe 10 is submerged 30-50 cm below the water surface, the servo motor 4 drives the shaft 7 to rotate. The rotation of the shaft 7 causes the pump impeller 13 and the stirring blade 14 to rotate synchronously. The rotation of the pump impeller 13 generates suction, and water is drawn in from the water pump pipe 10, while air is drawn in from the air inlet pipe 8. Finally, the water is sprayed out from the drain hole 20. The sprayed water is then dispersed by the rotating stirring blade 14, thus achieving aeration treatment of the water surface. Repeat the above steps, and then, based on the water depth measured by the electronic water level sensor, extend the stirring blade 14 to a depth of 30-50 cm from the bottom of the water, while keeping the top of the air inlet pipe 8 above the water surface. This will achieve aeration treatment for deep water bodies. Alternatively, the entire aeration device can be suspended in the middle layer of the water body to achieve aeration treatment for the middle layer of the water body. This application uses a single aeration device to perform aeration treatment for the surface, middle and lower layers of the water body according to the water conditions, thereby increasing the oxygen content of the water body. This saves the resources of aeration equipment.

[0024] After the aeration equipment below is adjusted to the position on the water surface, in the water or deep underwater by the lifting mechanism 2, the push column 17 is moved outward by the electric push rod 15. The friction round pad 18 and the long friction pad 19 squeeze each other, which locks the slider 3 in the position of the stand 1, so as to ensure that the aeration equipment hanging below will not slide down, thereby ensuring the stable operation of the aeration equipment.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
