Description

Technical Field

[0001] This application relates to the field of environmental protection equipment technology, and in particular to an aeration device for river water pollution treatment. Background Technology

[0002] In river management, the bottom aeration process has significant advantages over traditional methods such as dredging, surface aeration, biofilm method, and constructed wetland.

[0003] Compared with traditional aeration equipment (such as aeration discs, aeration heads, jet aerators, etc.), aeration hoses have significant advantages in river pollution treatment, such as high oxygen transfer efficiency, adaptability to complex river environments, convenient installation and maintenance, and strong anti-clogging ability.

[0004] An aeration hose is a flexible tubular aeration device, usually made of high-strength synthetic materials (such as rubber and PVC). The hose wall is covered with tiny aeration holes. When compressed air passes through the hose, it is released from the micropores in the form of tiny bubbles, making full contact with the water and improving oxygen transfer efficiency.

[0005] Aeration hoses need to be secured. During installation and replacement, they can be installed via drainage, underwater operation, or by using a liftable support to raise the entire hose to the water surface. However, riverbanks are relatively complex and it is not convenient to install liftable supports. Drainage or underwater installation procedures are also quite complicated. Therefore, there is an urgent need for an aeration device that is easy to install and replace. Summary of the Invention

[0006] This application proposes an aeration device for river water pollution control. The mounting sleeve is fixed by the gravity of the fixed sleeve, thereby keeping the fixed sleeve and the aeration hose on it fixed, which facilitates the installation and disassembly of the aeration hose. At the same time, the large gap between the various structures can reduce the impact of corrosion and silt, and has greater reliability.

[0007] To achieve the above objectives, this application adopts the following technical solution: an aeration device for river water pollution treatment, comprising anchor piles and aeration hoses arranged in sections. The anchor piles are connected to the aeration hoses via limiting rings. One end of the aeration hoses is connected to the main air supply pipe on the riverbank via a rubber riser. The other end of the aeration hoses is connected to a tension rope via a tail pull ring. The tension rope is connected to a fixed pile on the riverbank. The anchor piles include:

[0008] Insertion piles are inserted into the riverbed, and installation piles are fixedly connected to them.

[0009] The positioning sleeve is detachably mounted on the mounting pile. It includes a clamping sleeve with a flange at the bottom, and at least two sets of assembly grooves on its side wall. The assembly grooves are pivotally connected to limit blocks. The upper end of the limit block is provided with a passive wedge protruding from the side wall, and the bottom of the limit block is provided with a limit wedge.

[0010] The mounting sleeve includes a sliding sleeve, a limiting ring fixedly connected to the sliding sleeve, the sliding sleeve is fitted on the outer wall of the positioning sleeve and located on the flange, and corresponding positioning protrusions and positioning grooves are respectively provided between the flange and the sliding sleeve, and the upper end of the sliding sleeve is provided with an inner flange with a limiting slope.

[0011] The fixing sleeve is fitted on the outer wall of the positioning sleeve and located on the mounting sleeve. Its inner wall presses against the passive wedge, causing the limiting wedge to be close to the limiting slope.

[0012] Furthermore, it also includes an air mixing tube parallel to the aeration hose, with the same connection structure as the aeration hose, and the aperture of the air mixing tube is above 2mm.

[0013] Furthermore, the height of the inner flange is less than the distance between the passive wedge and the limiting wedge, so as to prevent the mounting sleeve from being unable to be lifted due to the obstruction of the limiting block.

[0014] Furthermore, the fixing sleeve is provided with a permanent magnet, and the position of the mounting sleeve or positioning sleeve corresponds to the positioning block of the permanent magnet. The permanent magnet attracts the positioning block, so that the fixing sleeve can better resist the influence of water flow.

[0015] Furthermore, the positioning sleeve is fixedly connected to two sets of positioning slide rods, and the positioning sleeve is fixedly connected to a float via the positioning slide rods. Both the mounting sleeve and the fixing sleeve are provided with slide grooves corresponding to the positioning slide rods. By observing the float, the movement of the anchor pile and the depth of the aeration hose can be determined so as to make timely adjustments.

[0016] Furthermore, the inner wall of the positioning sleeve is provided with a closed groove and a T-groove. The T-groove is arranged horizontally and is located in the middle of the closed groove. A clamping element is provided in the closed groove. The clamping element includes a vertically arranged double piston cylinder. Both ends of the double piston cylinder are fixedly connected to a pressing block. The side wall of the closed groove is provided with symmetrical pressing inclined surfaces. When the double piston cylinder retracts, the pressing inclined surfaces on both sides clamp the T-groove. When the double piston cylinder extends, the pressing block interacts with the pressing inclined surfaces, causing the pressing block to move axially. A T-block is movably connected to the T-groove. A clamping plate is fixedly connected to the T-block. The pressing block moves axially and presses the clamping plate, so that the clamping plates on both sides clamp the mounting pile.

[0017] Furthermore, the central part is movably connected with a stop block, and both the upper and lower ends of the stop block are provided with stop slopes. Both sides of the extrusion blocks are provided with corresponding abutment slopes. The included angle of the stop slopes is less than 30 degrees. A spring is provided between the T-block and the clamping sleeve. The spring keeps the stop block in a retracted state. The stop block is provided with a magnet that repels the permanent magnet. When the fixing sleeve is in place, the repulsive force of the permanent magnet causes the stop block to press against the extrusion block.

[0018] Furthermore, the installation pile is fixedly connected to a vertical pole with its end above the water surface, the float is slidably connected to the vertical pole, the side wall of the vertical pole is provided with a limiting protrusion, and the inner wall of the float is provided with a limiting groove. When fixing the positioning sleeve, the position of the float is adjusted up and down to adjust the depth of the positioning sleeve.

[0019] Furthermore, it also includes a lifting rod, and the fixing sleeve is fixedly connected to two lifting ropes. The upper ends of the two lifting ropes are fixedly connected to the lifting rod. The upper end of the upright is provided with a connecting plate, and the connecting plate is provided with a placement groove corresponding to the lifting rod. The upright is provided with several through holes, through holes into which a crossbar can be inserted. The crossbar can prevent the fixing sleeve from sliding down. The mounting sleeve and the fixing sleeve are connected by a connecting rope.

[0020] Furthermore, it also includes a lifting component, which includes a mounting plate and a lead screw. The mounting plate is detachably connected to the connecting plate. The mounting plate is connected to a drive nut via a rotating sleeve. The upright is hollow, and the lead screw can be inserted into the upright. The nut is threadedly connected to the lead screw. The drive nut is fixedly connected to a worm gear. A worm is provided on one side of the worm gear. The worm is connected to a rotating handle. The mounting plate is provided with a bracket to support the worm. Furthermore, it is an aeration device for river water pollution treatment.

[0021] The beneficial effects of this invention are as follows:

[0022] This application provides an aeration device for river water pollution treatment. By squeezing a passive wedge block against the inner wall of a fixed sleeve, the limiting wedge block is brought close to the limiting inclined surface, ensuring that the positioning protrusion and the positioning groove are always in a matching state. This keeps the fixed sleeve and the aeration hose on it fixed. During installation, the mounting sleeve and the fixed sleeve are simply put onto the positioning sleeve in sequence. When it needs to be removed and replaced, the mounting sleeve and the fixed sleeve are simply lifted in sequence. Installation and disassembly are convenient.

[0023] The various structures have large clearances, which can effectively reduce the impact of corrosion and silt, and ensure smooth movement of each structure during installation and disassembly, making it more reliable. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1, please refer to Figures 2-4 An aeration device for river water pollution treatment includes an aeration hose 4, an air mixing pipe 13, and anchor piles 5. The anchor piles 5 are connected to the aeration hose 4 and the air mixing pipe 13 via limiting rings 7. The aeration hose 4 and the air mixing pipe 13 are parallel. The anchor piles 5 are fixed to the riverbed, maintaining the aeration hose 4 and the air mixing pipe 13 at a set depth. Multiple sets of aeration hoses 4 are horizontally arranged and evenly distributed on the riverbed. One end of each aeration hose 4 is connected to a main air supply pipe 1 on the riverbank 12 via a rubber riser 2. A valve 3 is provided between the air supply main 1 and the rubber riser 2. The main air supply 1 has multiple branch pipes. The valve 3 is installed on the branch pipes. A clamp 6 is provided at the connection between the rubber riser 2 and the valve 3 to facilitate disassembly and installation. The other end of the aeration hose 4 is connected to a tail pull ring 8. The tail pull ring 8 closes the end of the aeration hose 4. The tail pull ring 8 is fixedly connected to a fixed pile 11 fixed on the riverbank 12 through a tension rope 9. The fixed pile 11 is fixedly connected to the tension rope 9 through a fixed ring 10. The tension rope 9 is tightened, thereby straightening the aeration hose 4.

[0037] Among them, the aeration hose 4 has a hollow tubular structure with a 3.0 mechanical pore size on the tube wall. The pore diameter is 0.5-2.0 mm and the pore density is 3500-24000 pores / meter. The microporous structure generates fine bubbles (about 100 μm in diameter), ensuring that the gas is released uniformly in the form of microbubbles, thereby improving the oxygen mass transfer efficiency. The aeration hose 4 is made of modified TPU material with the following formula: TPU matrix (hardness 85~95A) with 1~3 wt% anti-hydrolysis agent (such as polycarbodiimide) and 2~5 wt% carbon black (anti-UV aging), which is then blended and extruded. The modified TPU is resistant to sewage corrosion (anti-microbial / chemical erosion), has good flexibility (adapts to tank bottom deformation), and a smooth surface (anti-sludge adhesion properties). Its lifespan is more than 30% longer than that of conventional rubber aerators. The structure of the air mixing pipe 13 is largely the same as that of the aeration hose 4, except that the pore diameter is larger than 2mm, which is larger than that of the aeration hose 4. The larger pore diameter results in a larger air volume, and the larger bubble diameter also results in a higher rising speed, which can achieve rapid mixing of water from bottom to top. During aeration, the airflow released by the air mixing pipe 13 helps to disturb the sludge at the bottom of the tank, prevents sedimentation, and improves mass transfer efficiency.

[0038] To achieve precise aeration control, the aeration rate is regulated by a precision aeration system, which integrates an aeration execution unit, a multi-parameter sensing unit, and an intelligent control unit.

[0039] The aeration unit includes a blower control cabinet 19 and a flow regulating valve 15 for each zone. The blower control cabinet 19 adjusts the current frequency, thereby adjusting the speed of the blower 17 and controlling the total air volume. The blower 17 is also connected to a local control cabinet 18 for emergency manual control. Each zone has at least one main air supply pipe 1. Each main air supply pipe 1 is equipped with multiple sets of aeration hoses 4 and air mixing pipes 13. The flow regulating valve 15 adjusts the aeration volume of each section of the main air supply pipe 1. A distributor is provided between the aeration hoses 4, the air mixing pipes 13 and the main air supply pipe 1 to coordinate aeration and mixing.

[0040] The multi-parameter sensing unit includes dissolved oxygen meter 21 and thermometer 22 arranged in sections in the river, as well as pressure sensor 14 (monitoring pipe pressure and judging blockage / leakage) and aeration flow meter 16 installed on the main air supply pipe 1. In some embodiments, a fiber optic fluorescence sensor with higher anti-interference and accuracy can be used to replace dissolved oxygen meter 21 to monitor dissolved oxygen, and a sludge concentration sensor can be added to provide feedback on sludge activity in order to optimize the aeration strategy.

[0041] The intelligent control unit includes a precision aeration control cabinet 20, which uses a PLC and an industrial computer as its core. It supports algorithm iteration and data storage, and can acquire data from multi-parameter sensing units. Based on the algorithm, it drives the aeration execution unit to precisely control the aeration. In this field, conventional algorithms mainly include fuzzy adaptive PID algorithm, model predictive control, or closed-loop monitoring. For example, a fuzzy adaptive PID algorithm can be used to acquire multi-parameter sensing unit data, calculate the target aeration volume, and output control signals to the flow regulating valve 15 (to adjust the opening degree) and the blower control cabinet 19 (to adjust the output current frequency of the blower control cabinet 19, thereby adjusting the speed of the blower 17). When the dissolved oxygen deviates from the set value by ±0.5mg / L, or the ORP fluctuation exceeds 50mV, the algorithm automatically corrects the control parameters to ensure the stability of the biochemical process. The above algorithms are mature technologies in this field, and the specific algorithms will not be described in detail.

[0042] Please see Figure 1 , Figures 5-6To facilitate the installation and replacement of the aeration hose 4, the anchor pile 5 includes an insertion pile 501, an installation pile 502, a positioning sleeve 506, an installation sleeve 507, and a fixing sleeve 508. The insertion pile 501 is inserted into the riverbed. The insertion pile 501 and the installation pile 502 can be integrated or fastened together with bolts. A vertical pole 503 is fixedly connected to the end of the installation pile 502. The vertical pole 503 is installed on the installation pile 502 with bolts. Depending on the actual situation, a vertical pole 503 of appropriate length is selected and installed on the installation pile 502, so that the end of the vertical pole 503 is above the water surface. Positioning sleeve 506 is detachably mounted on mounting post 502. Positioning sleeve 506 includes clamping sleeve 5061, the bottom of which has a flange. Mounting sleeve 507 is placed on the flange of positioning sleeve 506. Mounting sleeve 507 includes sliding sleeve 5071, the flange of which has two or more positioning protrusions 5066. The bottom of sliding sleeve 5071 has positioning grooves 5073 corresponding to the positioning protrusions 5066. The positioning protrusions 5066 and positioning grooves 5073 cooperate to prevent mounting sleeve 507 from rotating. Clamping sleeve 5061 and limiting ring 7 are fixedly connected. The side wall of the clamping sleeve 5061 is provided with at least two sets of assembly grooves 5063. A limiting block 5062 is movably connected within the assembly groove 5063. A rotating shaft is fixedly connected to the limiting block 5062. The side wall of the assembly groove 5063 is provided with a shaft hole corresponding to the rotating shaft. To prevent sediment accumulation, both the assembly groove 5063 and the shaft hole penetrate the clamping sleeve 5061, allowing water flow to flush away sediment. A passive wedge 5064 is provided at the top of the limiting block 5062. The passive wedge 5064 has inclined surfaces on both its upper and lower sides. When the fixed sleeve 508 is movably engaged with the positioning sleeve 506, the upper end of the sliding sleeve 5071 is provided with… The device has an inner flange 5072, and the inner wall of the inner flange 5072 is provided with a limiting inclined surface 5074. The lower end of the limiting block 5062 is provided with a corresponding limiting wedge 5065. When the fixing sleeve 508 is fitted in, the inner wall presses the upper inclined surface of the passive wedge 5064, causing the limiting block 5062 to rotate. The limiting wedge 5065 at its bottom abuts against the limiting inclined surface 5074, thereby locking the position of the mounting sleeve 507. This prevents the positioning protrusion 5066 and the positioning groove 5073 from separating from each other, maintaining the relative stability of the mounting sleeve 507 and resisting the reaction force of the aeration hose 4. Simultaneously, when lifting, first lift the fixing sleeve 508, and the limiting block 5062 will be unrestrained. Then lift the mounting sleeve 507. Under the action of the lower inclined surface of the limiting wedge 5065 and the passive wedge 5064, the limiting block 5062 will be driven to rotate. The height of the inner flange 5072 is less than the distance from the lower inclined surface of the passive wedge 5064 to the limiting wedge 5065. That is, when the limiting inclined surface 5074 reaches the lower inclined surface of the passive wedge 5064, the limiting wedge 5065 passes over the inner flange 5072. The inner wall of the inner flange 5072 will not affect the rotation of the limiting block 5062, and there is no interference. The fixing sleeve 508 is provided with a permanent magnet. The position of the mounting sleeve 507 or the positioning sleeve 506 corresponds to the positioning block of the permanent magnet. The permanent magnet attracts the positioning block, which improves the stability of the fixing sleeve 508.

[0043] Please see Figure 5 and Figure 6 To ensure that the relative positions of the mounting sleeve 507 and the fixing sleeve 508 are consistent after they are fitted, the positioning sleeve 506 is fixedly connected to two sets of positioning slide rods 505. The positioning sleeve 506 is fixedly connected to a float 504 through the positioning slide rods 505. The depth of the positioning sleeve 506 is determined by the length of the float 504 that floats above the water surface. The mounting sleeve 507 and the fixing sleeve 508 are provided with grooves corresponding to the positioning slide rods 505. The inner side of the positioning slide rod 505 is fixedly connected to the positioning sleeve 506. The mounting sleeve 507 and the fixing sleeve 508 slide along the outer side of the fixing sleeve 508. The gap between the groove and the positioning slide rod 505 is large enough to ensure smooth sliding. The positioning slide rod 505 and the groove cooperate to achieve initial positioning, so that the positioning protrusion 5066 can cooperate with the positioning groove 5073.

[0044] Please see Figure 7 The inner wall of the positioning sleeve 506 is provided with a closed groove 5067 and a T-slot 5069. The T-slot 5069 is arranged horizontally and is located in the middle of the closed groove 5067. A clamping member 514 is provided in the closed groove 5067. The clamping member 514 includes a vertically arranged double piston cylinder 5143. Both ends of the double piston cylinder 5143 are fixedly connected to extrusion blocks 5141. The side wall of the closed groove 5067 is provided with symmetrical extrusion inclined surfaces 5068. When the double piston cylinder 5143 retracts, the extrusion inclined surfaces 5068 on both sides clamp the T-slot 5069. When the double piston cylinder 5143 extends, the extrusion blocks 5141 interact with the extrusion inclined surfaces 5068, causing the extrusion blocks 5141 to axially extend. The T-slot 5069 is movably connected to a T-block 5144, and the T-block 5144 is fixedly connected to a clamping plate 5142. The squeezing block 5141 moves axially and squeezes the clamping plate 5142, so that the clamping plates 5142 on both sides clamp the installation pile 502. The clamping plate 5142 and the T-block 5144 are connected by an elastic body. The size of the elastic body is smaller than that of 5169 to avoid being affected by mud and sand. One of the positioning slide rods 505 is hollow and has an air pipe inside. The air pipe is connected to the double piston cylinder 5143. The air valve is located on the water surface to facilitate the control of the double piston cylinder 5143. When it is inflated, the double piston cylinder 5143 extends; when it is deflated, the double piston cylinder 5143 retracts.

[0045] Since the clamping force of the clamping member 514 is provided by the high-pressure gas in the double piston cylinder 5143, leakage may cause the positioning sleeve 506 to be unstable. Therefore, a stop block 5145 is movably connected in the middle of 5167. The upper and lower ends of the stop block 5145 are provided with stop slopes, and the pressing blocks 5141 on both sides are provided with corresponding slopes. The included angle of the slopes is less than 30 degrees. A spring is provided between the T-shaped block 5144 and the clamping sleeve 5061. The spring keeps the stop block 5145 in a retracted state. The stop block 5145 is provided with a magnet that repels the permanent magnet. When the fixing sleeve 508 is in place, the repulsive force of the permanent magnet causes the stop block 5145 to press against the pressing block 5141. Since the included angle of the slope is small, it can ensure that the stop block 5145 can press against the pressing block 5141 and prevent the pressing block 5141 from moving backward, so that the positioning sleeve 506 is stably fixed.

[0046] To ensure that the clamping part 514 can move smoothly, a sealing felt 5146 is provided at the opening of the closed groove 5067. Since the opening of the closed groove 5067 is divided into two parts by the T-shaped groove 5069, the sealing felt 5146 is also divided into two parts. The sealing felt 5146 seals the closed groove 5067, preventing the parts inside from being corroded and also preventing the accumulation of mud and sand.

[0047] To ensure that the circumferential position of the positioning sleeve 506 is consistent, the float 504 is slidably connected to the upright 503. The side wall of the upright 503 is provided with a limiting protrusion, and the inner wall of the float 504 is provided with a limiting groove. When fixing the positioning sleeve 506, the position of the float 504 is adjusted up and down to adjust the depth of the positioning sleeve 506. Then, the double piston cylinder 5143 is inflated through the air pipe in the positioning slide rod 505, so that the clamping part 514 holds the installation pile 502 tightly. In order to improve stability, the side wall of the locking block 512 and the inner wall of the positioning sleeve 506 are both milled with two sets of opposing planes.

[0048] Please see Figure 4The fixing sleeve 508 is fixedly connected to two lifting ropes 509. Lifting lugs are provided on both sides of the fixing sleeve 508, and the lifting ropes 509 are tied to the lugs. The upper ends of the two lifting ropes 509 are fixed to the lifting rod 510. A connecting plate 511 is provided at the upper end of the upright rod 503. The connecting plate 511 has a placement groove corresponding to the lifting rod 510. Mounting holes on the connecting plate 511 can be used to install clamps to prevent the lifting rod 510 from falling. The fixing sleeve 508 is connected to the mounting sleeve 507 via connecting ropes. The upright rod 503 has several through holes into which a clamp can be inserted. When it is necessary to replace or install the aeration hose 4, the crossbar is used to pull the fixing sleeve 508 and the mounting sleeve 507 out of the water surface by the lifting rope 509. Since the mounting sleeve 507 and the fixing sleeve 508 are connected by a connecting rope, there is a clear sequence when they are lifted. That is, the mounting sleeve 507 is lifted only after the limiting block 5062 is released. After the fixing sleeve 508 is lifted out of the water surface, the crossbar is inserted into the through hole below the fixing sleeve 508 to stabilize the fixing sleeve 508 and the mounting sleeve 507 on the water surface so that the aeration hose 4 can be installed or replaced.

[0049] To facilitate lifting of the mounting sleeve 507 and the fixing sleeve 508, a lifting component 513 is also included. The lifting component 513 includes a mounting plate 5131 and a lead screw 5136. The mounting plate 5131 is temporarily mounted on the connecting plate 511 by a limiting pin, which is inserted into the mounting holes of the connecting plate 511 and the mounting plate 5131. The mounting plate 5131 is connected to a driving nut 5133 by a rotating sleeve 5132. The upright 503 is hollow, and the lead screw 5136 can be inserted into the upright 503. The nut 5133 is threadedly connected to the lead screw 5136, and the rotation of the nut 5133 drives the lead screw 5136. 6. To prevent the lead screw 5136 from rotating synchronously with the drive nut 5133, a limiting groove 5137 is provided on the side wall of the lead screw 5136. A protrusion corresponding to the limiting groove 5137 is provided on the mounting plate 5131. To facilitate the rotation of the drive nut 5133, a worm gear 5134 is fixedly connected to the drive nut 5133. A worm 5135 is provided on one side of the worm gear 5134. A rotating handle is connected to the worm 5135. A bracket supporting the worm 5135 is provided on the mounting plate 5131. A clamping plate 5138 capable of clamping the lifting rod 510 is provided on the top of the lead screw 5136.

[0050] When it is necessary to lift the mounting sleeve 507 and the fixing sleeve 508, first remove the lifting rod 510, adjust the lead screw 5136 to the lowest position and insert it into the upright 503, then install the mounting plate 5131 on the connecting plate 511, then place the lifting rod 510 on the clamping plate 5138 and fix it, turn the handle to move the lead screw 5136 upward, thereby lifting the lifting rod 510 and lifting the mounting sleeve 507 and the fixing sleeve 508. After the fixing sleeve 508 is lifted out of the water, insert the crossbar under the fixing sleeve 508, then remove the lifting rod 510, remove the lifting component 513, and put the lifting rod 510 back on the connecting plate 511 to complete the lifting of one mounting sleeve 507 and the fixing sleeve 508.

[0051] When it is necessary to lift the aeration hose 4, close the corresponding valve 3, first loosen the tension rope 9 on the fixing ring 10, and then lift the anchor piles 5 one by one starting from the side of the fixing ring 10.
