Technical Field

[0001] The invention relates to a river mixed oxygenation and pollution removal device, belonging to the technical field of mixed oxygenation. Background Art

[0002] Most conventional oxygenation equipment achieves the purpose of oxygenation by directly introducing gas into the water body to increase the solubility of oxygen in the water body. However, since oxygen is almost insoluble in water, even if gas is continuously introduced into the water body, the gas entering the water body will gather to form large bubbles and quickly float to the surface of the water body, and finally dissipate into the atmosphere. This will result in poor oxygenation effect on river water bodies, so there are certain problems. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a river channel mixed oxygenation and pollution removal equipment, which solves the problem of poor oxygenation effect of conventional oxygenation equipment in the prior art by premixing oxygen and water.

[0004] The technical problem to be solved by the present invention is achieved by adopting the following technical scheme: a river channel hybrid oxygenation and pollution removal equipment, including a connecting body, an air guide pipe, a water inlet pipe, an oxygenation body, a rotating column, an air guide joint, an intermediate cavity, a fixing ring, a disturbance block, a driving structure and an anti-backflow component, the connecting body and the oxygenation body are coaxially fixedly arranged, the interior of the oxygenation body is hollow and arranged to form a mixing cavity, a through channel is provided on the side of the mixing cavity away from the connecting body, the rotating column and the oxygenation body are coaxially rotatably arranged, one end of the rotating column is located between the connecting body and the oxygenation body, the other end of the rotating column extends into the mixing cavity, and the air guide joint is coaxially fixedly arranged on the rotating column One end of the air guide pipe is sleeved on the end of the air guide joint, and the other end of the air guide pipe extends to the outside of the connecting body. The intermediate cavity is opened in the rotating column and is connected with the air guide joint. The fixing ring is fixedly sleeved on the rotating column at one end of the mixing chamber. The disturbance block is fixedly arranged on the fixing ring. The inner wall of the intermediate cavity is connected to an air guide channel. The other end of the air guide channel passes through the disturbance block. The anti-backflow component is arranged on the disturbance block and closes the air guide channel. One end of the water inlet pipe is connected with the mixing chamber, and the other end of the water inlet pipe extends to the outside of the connecting body. The driving structure is fixedly arranged between the connecting body and the oxygenation body. The driving structure is dynamically connected to the rotating column and drives the rotating column to rotate.

[0005] By adopting the above technical solution, the air guide pipe is connected with the external oxygen supply equipment, and the oxygen supply equipment passes oxygen into the middle cavity through the air guide pipe. The oxygen entering the middle cavity passes through the air guide channel and the anti-backflow component and then flows into the mixing cavity. When the oxygen increase body is placed below the water surface of the river channel, the river water can fill the mixing cavity, and the residual air in the mixing cavity can be discharged through the water inlet pipe. At this time, oxygen is continuously introduced into the mixing cavity. After the driving structure drives the rotating column to rotate, the rotating column drives the disturbance block to rotate through the fixed ring, so that the disturbance block disturbs the water flow in the mixing cavity. After oxygen is synchronously introduced into the mixing cavity, the larger oxygen bubbles can be broken up into a large number of dispersed small bubbles, and a large number of small bubbles are fully mixed with the water body, and then flow out of the mixing cavity with the water flow. At this time, the dispersed small bubbles can remain in the water body longer than the large bubbles, and the organisms in the water body can better absorb oxygen, thereby achieving the purpose of oxygenating the river channel. At the same time, compared with the traditional method of directly introducing oxygen into the water body, such an oxygenation effect is better.

[0006] The present invention is further configured as follows: the driving structure includes a driving motor and a driving gear, the driving motor is fixed on the side of the connecting body facing the oxygen enrichment body, the driving motor is provided with an output end, the output end of the driving motor is dynamically connected to the driving gear, and the driving gear is meshed with the outer side teeth of the rotating column.

[0007] By adopting the above technical solution, the driving motor drives the driving gear to rotate after starting. Since the driving gear is meshed with the rotating column teeth, the rotating column is driven to rotate during the rotation of the driving gear, thereby achieving the purpose of driving the rotating column to rotate.

[0008] The present invention is further configured as follows: the anti-backflow component includes a shielding cylinder, a sliding block, a sliding cavity, a fixed plate, a reset spring, an exhaust hole and a protective structure; the shielding cylinder is hollow and configured to form an active cavity; the active cavity penetrates one end of the shielding cylinder toward the disturbance block; the active cavity is communicated with the air guide channel; the sliding cavity is arranged in the disturbance block and is located on the side of the air guide channel; a plurality of sliding cavities are provided and the sliding cavity penetrates the disturbance block in the direction of the shielding cylinder; the sliding block is fixed to one end of the shielding cylinder toward the disturbance block; the number and position of the sliding blocks are the same as those of the sliding cavity and there are intervals between adjacent sliding blocks; the sliding block extends from one end of the shielding cylinder to the sliding cavity; the sliding block passes the disturbance block along the air guide channel The opening passing through the block slides toward the front, the fixed plate is fixed in the air guide channel, a first limit block is fixed on one end of the fixed plate facing the shielding tube, a second limit block is fixed on the inner wall of the active cavity opposite to the fixed plate, two ends of the reset spring are respectively mounted on the second limit block and the first limit block, two ends of the reset spring are respectively fixedly connected to the fixed plate and the inner wall of the active cavity, a number of exhaust holes are provided, and a number of exhaust holes are opened on the side of the outer curved surface of the shielding tube away from the disturbance block, the exhaust holes connect the active cavity with the outside of the shielding tube, the protective structure is provided in the active cavity and always blocks and closes the interval between adjacent sliding blocks, and the protective structure can block and close the connection between the exhaust hole and the active cavity.

[0009] The present invention is further configured as follows: the protective structure includes a hard inner liner, a flexible expansion sheet and an inflation channel, the hard inner liner is arranged in the active cavity, there is a gap between the hard inner liner and the active cavity and the end of the hard inner liner is fixed to the disturbance block, the flexible expansion sheet is arranged in the gap between the hard inner liner and the inner wall of the active cavity and the flexible expansion sheet is in contact with the inner wall of the active cavity, the flexible expansion sheet is fixedly connected to the hard inner liner, a sealed inflation cavity is surrounded by the hard inner liner and the flexible expansion sheet, the inflation channel is opened in the disturbance block, one end of the inflation channel is connected to the air guide channel, and the other end of the inflation channel is connected to the inflation cavity.

[0010] By adopting the above technical scheme, since the oxygenation body is placed directly in the river channel, the foreign matter retained in the river channel will enter the mixing chamber synchronously, and some of the foreign matter will block the opening of the air guide channel. By installing a shielding cylinder and a sliding block on the disturbance block, the oxygen first enters the active chamber and then is discharged into the water in the mixing chamber through the exhaust hole. At this time, the exhaust hole can screen and filter some foreign matter to avoid direct blockage of the air guide channel by foreign matter. In addition, since the mixing chamber is full of water, the pressure in the air guide channel returns to atmospheric pressure after the external oxygen supply equipment stops supplying oxygen. At this time, the water in the mixing chamber will flow back into the air guide channel and fill the middle chamber, resulting in water retention inside the equipment. At this time, by providing a hard liner cylinder, a flexible expansion sheet, a fixed plate and a reset spring, it can be made The shielding cylinder moves toward the disturbance block under the elastic action of the return spring. Since the hard liner cylinder and the flexible expansion sheet are fixed to the disturbance block, the shielding cylinder slides relative to the hard liner cylinder at this time, and the flexible expansion sheet can close the opening of the exhaust hole, thereby isolating the water flow in the mixing chamber from flowing into the active chamber through the exhaust hole, avoiding the backflow of water flow, and keeping the interior of the equipment in a dry and water-free state at all times. When the oxygen supply equipment continues to supply oxygen, the pressure in the air guide channel and the active chamber increases. When the pressure in the air guide channel is greater than the water pressure in the mixing chamber, the shielding cylinder moves in the direction away from the disturbance block until the flexible expansion sheet releases the seal on the exhaust hole. At this time, the oxygen in the active chamber passes into the mixing chamber through the exhaust hole, achieving the purpose of automatic closing and opening of the exhaust hole by the flexible expansion sheet.

Two mounting bodies 10 are arranged side by side, two transmission wheels 14 are arranged and are rotatably arranged inside the two mounting bodies 10 respectively, the two ends of the transmission chain 13 are wound around the two transmission wheels 14, the fixed connection block 15 is fixedly installed on the transmission chain 13, the external motor 12 is fixedly arranged on the outside of the mounting body 10 and is connected to the transmission wheel 14 by power, the fixed pile 11 is fixedly arranged on the outer side of the mounting body 10 opposite to the external motor 12, and the fixed connection block 15 is connected to the connection body 20 by mortise and tenon joints. The outer side surface of the oxygenation body 24 close to the transmission chain 13 is fixedly provided with an auxiliary connection block 65, and the two mounting bodies 10 are fixedly provided with elastic bands 64, and the elastic bands 64 extend to the auxiliary connection block 65 at one end away from the mounting body 10 and are connected to the auxiliary connection block 65 by mortise and tenon joints. When in use, the fixed piles 11 are inserted into the embankment soil layers on both sides of the river channel to complete the fixed installation of the auxiliary components, and then the fixed connection block 15 is connected with the connection body 20 by mortise and tenon joints, so that the connection body 20 can follow the movement of the fixed connection block 15, and then the end of the elastic band 64 is connected with the auxiliary connection block 65 by mortise and tenon joints. At this time, the elastic band 64 is stretched, and a pulling force is applied to the oxygenation body 24 along the extension direction of the transmission chain 13, thereby improving the fixed connection block 15 to drive the connection body 20 to follow the movement of the transmission chain 13, and the overall problem of the oxygenation body 24 and the connection body 20 To solve the problem, in order to avoid large shaking of the connecting body 20 and the oxygen enrichment body 24 that affects the operation of the rotating column 30, the external motor 12 is started to drive the transmission wheel 14 to rotate, thereby driving the transmission chain 13 to move around the two transmission wheels 14, and then driving the connecting body 20 to move through the fixed connecting block 15. At this time, the connecting body 20 can move toward the two installation bodies 10 respectively in a straight line direction, so as to achieve the purpose of adjusting the position of the connecting body 20. During the movement of the connecting body 20, the two elastic bands 64 will be further stretched, but neither reaches the limit stretching amount.

[0025] The air guide tube 21 is connected to the external oxygen supply device, and the oxygen supply device passes oxygen into the middle cavity 33 through the air guide tube 21. The oxygen entering the middle cavity 33 flows into the mixing cavity 34 through the air guide channel 32 and the anti-backflow component. When the oxygen increase body 24 is placed below the water surface of the river, the river water can fill the mixing cavity 34, and the residual air in the mixing cavity 34 can be discharged through the water inlet pipe 22. At this time, oxygen is continuously passed into the mixing cavity 34. After the driving structure drives the rotating column 30 to rotate, the rotating column 30 drives the disturbance block 36 to occur through the fixing ring 35. Rotate, so that the disturbance block 36 disturbs the water flow in the mixing chamber 34. After oxygen is introduced into the mixing chamber 34 synchronously, the larger oxygen bubbles can be broken up into a large number of dispersed small bubbles. A large number of small bubbles are fully mixed with the water body, and then flow out of the mixing chamber 34 with the water flow. At this time, the dispersed small bubbles can remain in the water body longer than the large bubbles, and the organisms in the water body can better absorb oxygen, thereby achieving the purpose of increasing oxygen in the river channel. At the same time, compared with the traditional method of directly introducing oxygen into the water body, such an oxygenation effect is better. After the drive motor 27 is started, it drives the drive gear 28 to rotate. Since the drive gear 28 is meshed with the rotating column 30, the rotating column 30 is driven to rotate during the rotation of the drive gear 28, thereby achieving the purpose of driving the rotating column 30 to rotate.

[0026] Since the oxygenation body 24 is placed directly in the river channel, foreign matter retained in the river channel will enter the mixing chamber 34 synchronously, and some of the foreign matter will block the opening of the air guide channel 32. By installing the shielding tube 50 and the sliding block 51 on the disturbance block 36, the oxygen first enters the active chamber 63, and then is discharged into the water in the mixing chamber 34 through the exhaust hole 61. At this time, the exhaust hole 61 can screen and filter some foreign matter to prevent the foreign matter from directly blocking the air guide channel 32. In addition, since the mixing chamber 34 is full of water, the pressure in the air guide channel 32 returns to the atmospheric pressure after the external oxygen supply equipment stops supplying oxygen. At this time, the water in the mixing chamber 34 will flow back into the air guide channel 32 and fill the middle chamber 33, resulting in water retention inside the equipment. At this time, by setting the hard liner tube 57 and the flexible expansion sheet 58 as well as the fixing plate 53 and the reset spring 55, the shielding tube 50 can be reset after the reset spring 55 is reset. Under the elastic action of the shielding tube 50, it moves toward the disturbance block 36. Since the hard liner tube 57 and the flexible expansion sheet 58 are fixed to the disturbance block 36, the shielding tube 50 slides relative to the hard liner tube 57 at this time, and the flexible expansion sheet 58 can close the opening of the exhaust hole 61, thereby isolating the water flow in the mixing chamber 34 from flowing into the active chamber 63 through the exhaust hole 61, avoiding the backflow of water flow, and keeping the interior of the equipment in a dry and water-free state. When the oxygen supply equipment continues to supply oxygen, the pressure in the air guide channel 32 and the active chamber 63 increases. When the pressure in the air guide channel 32 is greater than the water pressure in the mixing chamber 34, the shielding tube 50 moves in the direction away from the disturbance block 36 until the flexible expansion sheet 58 releases the seal on the exhaust hole 61. At this time, the oxygen in the active chamber 63 passes into the mixing chamber 34 through the exhaust hole 61, achieving the purpose of automatic closing and opening of the exhaust hole 61 by the flexible expansion sheet 58.

[0027] And because when the shielding cylinder 50 moves toward the disturbance block 36, several sliding blocks 51 will also be recovered into the sliding chamber 52. In actual working conditions, since the mixing chamber 34 directly drains the water in the river channel, foreign matter carried in the water will remain between adjacent sliding blocks 51, that is, remain in the space on the side of the shielding cylinder 50 facing the disturbance block 36. At this time, when the shielding cylinder 50 moves toward the disturbance block 36, the foreign matter will first abut against the disturbance block 36, affecting the further movement of the shielding cylinder 50, making it impossible for the shielding cylinder 50 to move to the specified position. Therefore, an inflation channel 60 and an inflation chamber 59 are provided. When oxygen is introduced into the air guide channel 32, the pressure in the air guide channel 32 is greater than the pressure in the mixing chamber 34, and the shielding cylinder 50 begins to move toward the far It moves in the direction away from the disturbance block 36. At this time, part of the gas in the air guide channel 32 enters the inflation channel 60 to increase the pressure in the inflation chamber 59. At this time, the part of the flexible expansion sheet 58 located at the interval between adjacent sliding blocks 51 expands toward the interval between adjacent sliding blocks 51, so that the flexible expansion sheet 58 fills the interval between adjacent sliding blocks 51, while the flexible expansion sheet 58 located in the active chamber 63 is in a normal state and always fits with the inner wall of the active chamber 63. At this time, foreign matter inside the mixing chamber 34 will not be able to enter the interval between adjacent sliding blocks 51, and therefore will not interfere with the normal sliding of the shielding tube 50, thereby ensuring the smooth resetting of the shielding tube 50 and the normal shielding and closure of the exhaust hole 61 by the flexible expansion sheet 58.

[0028] Insert the end of the auxiliary regulating column 40 into the mixing chamber 34, so that the auxiliary regulating column 40 and the oxygenation body 24 are fixedly connected by inserting the connecting piece into the assembly hole 39. At this time, the auxiliary regulating column 40 closes the through-channel, and the water in the mixing chamber 34 cannot flow out through the connection between the auxiliary regulating column 40 and the through-channel. Connect the water inlet pipe 22 to the water pump structure with a coarse filter screen outside. The coarse filter screen in the water pump structure filters out large foreign matter in the river water, and then pump the water into the mixing chamber 34 through the water inlet pipe 22 and enter the mixing chamber 34. After the water in the cavity 34 is supplied with oxygen by the oxygen supply device and disturbed by the disturbance block 36, a large number of oxygen bubbles are contained in the water. At this time, the water flows into the filter cavity 49 through the transfer channel 41. After fine filtration by the filter element 62, the filtered water is discharged into the river through the drainage channel 48, thereby achieving the purpose of oxygenating and removing pollutants from the river water. Before use, according to the depth of the river water, the adjusting block 45 is rotated to make the adjusting block 45 and the auxiliary adjusting column 40 rotate relative to each other, and the adjusting block is made to rotate relative to each other under the action of the threaded structure. 45 extends from or retracts into the regulating chamber 42, and the filter mounting block 47 moves with the regulating block 45, thereby achieving the purpose of adjusting the depth of the discharged water body, so that the water body after aeration and decontamination can be transported to the bottom of the river as much as possible, so that the oxygen in the water body can be further prolonged in the water body, and the oxygenation effect on the water body is improved. When the filter element 62 needs to be replaced after being used for a long time, when the aeration and decontamination equipment is not in use, the filter mounting block 47 is rotated to drive the assembly column 46 to rotate, and the regulating device is grasped at the same time. Block 45, make the adjusting block 45 stationary and rotate relative to the assembly column 46, under the action of the threaded structure, the filter installation block 47 is gradually moved away from the adjusting block 45, and finally the assembly column 46 is disconnected from the adjusting block 45, and then the filter element 62 is pulled out of the filter cavity 49 along the axial direction, and the new filter element 62 is inserted into the filter cavity 49 to complete the installation of the filter element 62, and then the assembly column 46 and the adjusting block 45 are abutted and rotated in the opposite direction to the starting position to complete the replacement. The replacement operation is simple, which is conducive to reducing the difficulty of maintenance of the oxygenation and decontamination equipment.
