Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment devices, and in particular to a tea filter paper pulp wastewater treatment device with a fiber collection function. Background Art

[0002] The sewage generated during the production of tea filter paper contains a large amount of fibers, acid-base substances and resins. Therefore, it needs to be purified through a series of processes before being discharged. Currently, the sewage treatment generally uses technologies such as air flotation, adsorption, combined chemical processes and membrane filtration for purification. The current air flotation machines are mainly divided into several areas such as a dissolved air area, a flocculation area, an air flotation area, and a slag scraping area. When the wastewater is injected into the air flotation machine, it passes through the flocculation area, causing the impurities contained in the wastewater to agglomerate with each other. When the flocculated wastewater flows from the flocculation area to the air flotation area, it enters from the bottom and exits from the top. During the subsequent process of flowing from the air flotation area to the slag scraping area, the solid impurities contained in the wastewater are easily affected by the water flow and accumulate at the junction of the side wall of the air flotation area and the upper surface of the wastewater. In the subsequent slag scraping process, the slag scraping plate cannot effectively cover this position, affecting the cleaning effect of the slag scraping plate on the floating slag in the air flotation machine.

Detailed implementation manners

[0020] The following further illustrates the technical solution in combination with specific embodiments. It should be noted that: The words indicating directions such as up, down, left, and right mentioned in this article are only in terms of the positions of the shown structures in the corresponding drawings. The serial numbers assigned to the components in this article itself, for example: first, second, etc., are only used to distinguish the described objects and do not have any sequential or technical meanings.

[0021] Embodiment 1: A tea filter paper pulp wastewater treatment device with a fiber collection function, as Figures 1-4As shown in the figure, it includes a housing 1. The upper part on the left side of the housing 1 is fixedly connected with a dissolved air tank 2. The front side of the outer wall of the housing 1 is fixedly connected and communicated with a reflux pipe 20. The reflux pipe 20 is fixedly connected and communicated with the dissolved air tank 2. The reflux pipe 20 is used to transport the clear water in the housing 1 into the dissolved air tank 2 to supplement the consumed water in the dissolved air tank 2. The housing 1 is fixedly connected with an air diffuser pipe 3 in a penetrating manner. The air diffuser pipe 3 is fixedly connected and communicated with the dissolved air tank 2. A flow guide plate 4 is fixedly connected to the left side inside the housing 1. There is a gap between the lower side of the flow guide plate 4 and the bottom of the housing 1. The flow guide plate 4 is used to guide the wastewater transported into the housing 1. Between the flow guide plate 4 and the housing 1, there are a water inlet pipe, a chemical addition pipe (used to add flocculants and coagulants into the housing 1), and a stirring device. The water inlet pipe and the chemical addition pipe are both existing devices and are not shown in the figure. The stirring device is a motor and a stirring shaft. A partition plate 5 is fixedly connected to the inside of the housing 1. An aeration device (the aeration device is an existing device and is not shown in the figure) is arranged on the air diffuser pipe 3 between the flow guide plate 4 and the partition plate 5, which is used to transport the tiny bubbles in the dissolved air tank 2 into the housing 1. A transmission device 6 is arranged on the outer wall of the housing 1. The transmission device 6 is composed of a motor, a belt transmission device, and a chain transmission device. A slag scraping mechanism for scraping suspended substances is arranged on the chain of the chain transmission part in the transmission device 6. Two electric push rods 7 are symmetrically distributed in the front and back and fixedly connected to the upper side of the housing 1. The telescopic ends of the two electric push rods 7 are both fixedly connected with fixed shells 8. The two fixed shells 8 are both slidably connected to the housing 1. A connecting rod 9 is rotatably connected to the opposite sides of the two fixed shells 8. The connecting rod 9 is fixedly connected with a moving plate 10. The moving plate 10 is located on the right side of the flow guide plate 4 and is in contact with it. The two electric push rods 7 drive the moving plate 10 to move together, pushing the solid impurities squeezed at the junction of the flow guide plate 4 and the wastewater to the right. The housing 1 is provided with a drain port. The symmetrically distributed fixed shells 8 are jointly provided with a limiting component for fixing the moving plate 10.

[0022] As Figure 3 and Figure 4As shown, the limiting component includes two ratchets 21 that are symmetrically distributed front and back. The two ratchets 21 are respectively fixedly connected to the adjacent connecting rods 9. The two ratchets 21 are respectively located inside the adjacent fixed shells 8. A torsion spring is fixedly connected between each of the two ratchets 21 and the adjacent fixed shell 8. In the initial state, the torsion spring has been preloaded. Two fixed rods 22 are slidably connected through the two fixed shells 8. A spring is fixedly connected between the fixed rod 22 and the adjacent fixed shell 8 to maintain the initial position of the adjacent fixed rod 22 and drive the moved fixed rod 22 to reset to the initial position. The fixed rod 22 is rotatably connected to a pawl 23 that is in limiting cooperation with the adjacent ratchet 21. The pawl 23 is located inside the adjacent fixed shell 8. A torsion spring is fixedly connected between the pawl 23 and the adjacent fixed rod 22 to maintain the initial position of the pawl 23 and drive the moved pawl 23 to reset to the initial position. Two fixed blocks 24 that are symmetrically distributed front and back are fixedly connected to the upper side of the outer shell 1. The two fixed blocks 24 are respectively in contact and cooperation with the adjacent fixed rods 22. When the two fixed shells 8 move to the right, the two fixed rods 22 are respectively limited by the adjacent fixed blocks 24, and the two fixed rods 22 respectively move in opposite directions to the adjacent fixed shells 8, so that the pawl 23 loses cooperation with the adjacent ratchet 21, and the torsion spring between the ratchet 21 and the adjacent fixed shell 8 resets.

[0023] As Figure 2 , Figure 5 and Figure 6 shown, the slag scraping mechanism includes four first telescopic plates 31 that are equidistantly distributed. The four first telescopic plates 31 are respectively fixedly connected to the chain in the transmission device 6 through connectors. The telescopic part of the first telescopic plate 31 is rotatably connected to a second telescopic plate 32. The telescopic part of the second telescopic plate 32 is rotatably connected to a first connecting plate 33. The first connecting plate 33 is rotatably connected to a second connecting plate 34. In the initial state, the first telescopic plate 31 and the adjacent second telescopic plate 32 are perpendicular to each other, the second telescopic plate 32 and the adjacent first connecting plate 33 are perpendicular to each other, and the first connecting plate 33 and the adjacent second connecting plate 34 are perpendicular to each other. The first telescopic plate 31, the adjacent second telescopic plate 32, the adjacent first connecting plate 33, and the adjacent second connecting plate 34 cooperate with each other to form a ladle shape to intercept and store the floating slag. A slag removal table 35 that is slidably matched with the second connecting plate 34 is fixedly connected to the right side inside the outer shell 1. The slag removal table 35 cooperates with the second connecting plate 34 and other parts connected thereto to divert the intercepted floating slag. A slag discharge port is provided between the right side of the slag removal table 35 and the outer shell 1 to discharge the floating slag and collect the floating slag. The first telescopic plate 31 is provided with a moving component for changing the positions of the adjacent second telescopic plate 32, first connecting plate 33, and second connecting plate 34.

[0024] As Figure 6As shown in the figure, the moving component includes two hydraulic telescopic rods 41 that are symmetrically distributed front and back. Both hydraulic telescopic rods 41 are fixedly connected to the adjacent first telescopic plate 31 through connectors. During the process of the first telescopic plate 31 moving to the right, it drives the two adjacent hydraulic telescopic rods 41 to move synchronously. The telescopic ends of both hydraulic telescopic rods 41 are fixedly connected with moving rods 42. The inner wall of the housing 1 is provided with symmetrically distributed limiting grooves. The moving rods 42 are slidably matched with the adjacent limiting grooves on the housing 1. The symmetrically distributed limiting grooves in the housing 1 are composed of two U-shaped grooves and two inclined grooves. And the diameters of the arcs of the two U-shaped grooves on the same limiting groove increase synchronously with the increase of the distance from the dissolved air tank 2. The two inclined grooves on the same limiting groove are symmetrically distributed up and down. During the movement of the hydraulic telescopic rod 41, it drives the adjacent moving rod 42 to move synchronously. And during the movement of the moving rod 42, it is limited by the adjacent limiting groove on the housing 1 to move, so as to drive the telescopic ends of the adjacent hydraulic telescopic rods 41 to move. The fixed parts of both hydraulic telescopic rods 41 are fixedly connected and communicated with connecting pipes 43. The first telescopic plate 31 is fixedly connected with two first hydraulic push rods 44 that are symmetrically distributed front and back. The telescopic ends of the first hydraulic push rods 44 are hinged with first connectors 441 that are slidably connected to the adjacent second telescopic plate 32. The second telescopic plate 32 is provided with a chute for slidably connecting with the adjacent first connector 441. The telescopic ends of the first hydraulic push rods 44 drive the adjacent first connectors 441 to move. While moving, the first connectors 441 drive the adjacent second telescopic plates 32 to rotate around their connection points with the adjacent first telescopic plates 31. The second telescopic plate 32 is fixedly connected with two second hydraulic push rods 45 that are symmetrically distributed front and back. The telescopic ends of the second hydraulic push rods 45 are hinged with second connectors 451 that are slidably connected to the adjacent first connecting plate 33. The first connecting plate 33 is provided with a chute for slidably connecting with the adjacent second connector 451. The telescopic ends of the second hydraulic push rods 45 drive the adjacent second connectors 451 to move. While moving, the second connectors 451 drive the adjacent first connecting plates 33 to rotate around their connection points with the adjacent second telescopic plates 32. The first connecting plate 33 is fixedly connected with two third hydraulic push rods 46 that are symmetrically distributed front and back. The telescopic ends of the third hydraulic push rods 46 are hinged with third connectors 47 that are slidably connected to the adjacent second connecting plate 34. The second connecting plate 34 is provided with a chute for slidably connecting with the adjacent third connector 47. The telescopic ends of the third hydraulic push rods 46 drive the adjacent third connectors 47 to move. While moving, the third connectors 47 drive the adjacent second connecting plates 34 to rotate around their connection points with the adjacent first connecting plates 33. The fixed parts of the third hydraulic push rods 46, the fixed parts of the second hydraulic push rods 45, and the fixed parts of the first hydraulic push rods 44 are all fixedly connected and communicated with the adjacent connecting pipes 43. The first hydraulic push rod 44 transports the hydraulic oil in it to the fixed parts of the adjacent third hydraulic push rod 46, the fixed parts of the adjacent second hydraulic push rod 45, and the fixed parts of the adjacent first hydraulic push rod 44 through the connecting pipe 43.Furthermore, the telescopic ends of the adjacent third hydraulic push rods 46, the telescopic ends of the adjacent second hydraulic push rods 45, and the telescopic ends of the adjacent first hydraulic push rods 44 extend outwards. The upper side of the slag removal table 35 is set to be arc-shaped, and the center of the arc of the slag removal table 35 is collinear with the center of the arc on the right side of the limit groove on the outer shell 1. After the second connecting plate 34 moves to the vertical state, the second connecting plate 34 always fits against the upper side surface of the slag removal table 35 and cooperates with the upper side surface of the slag removal table 35 during subsequent movement to guide the intercepted floating slag.

[0025] When using this device, the staff first transports the wastewater generated by papermaking (hereinafter referred to as wastewater) to the inside of the outer shell 1 through the water inlet pipe. At the same time, the flocculant and coagulant aid (hereinafter referred to as medicine) are synchronously added to the outer shell 1 through the medicine adding pipe. At the same time, the staff starts the stirring device, and the stirring device stirs the wastewater and medicine in the outer shell 1 to increase the dissolution rate of the medicine and cause the impurities (such as fibers) contained in the wastewater to precipitate and agglomerate.

[0026] While the staff transports the wastewater and medicine to the outer shell 1, the staff starts the dissolved air tank 2, and the tiny bubbles in the dissolved air tank 2 are transported to the aeration device through the aeration pipe 3. Then, the tiny bubbles are dispersed into the outer shell 1 through the aeration device. The tiny bubbles carry the agglomerated solid impurities (hereinafter referred to as floating slag) to the upper surface of the wastewater. Until the liquid level of the wastewater in the outer shell 1 reaches the specified height (that is, the liquid level of the wastewater in the outer shell 1 is above the partition plate 5), the staff opens the drain port on the outer shell 1 while continuously injecting wastewater into the outer shell 1, and the clear water in the outer shell 1 is discharged. At the same time, the return pipe 20 is opened, and a part of the clear water in the outer shell 1 is transported to the dissolved air tank 2 through the return pipe 20 to maintain the generation amount of tiny bubbles inside the dissolved air tank 2.

[0027] After the liquid level of the wastewater in the outer shell 1 reaches the specified height, the staff starts the transmission device 6, and the transmission device 6 drives the four first telescopic plates 31 on it and other devices connected thereto to move synchronously. The following takes the movement process of the first telescopic plate 31 on the lower left as an example for description: The transmission device 6 drives the first telescopic plate 31 and other parts connected thereto to move synchronously to the right, so that the floating slag on the wastewater liquid surface is pushed to the right by the first telescopic plate 31. At this time, the floating slag on the wastewater liquid surface is affected by the acting force of the first telescopic plate 31 and accumulates at the junction of the first telescopic plate 31 and the wastewater. And the accumulation part is divided into two parts, underwater and above water. Among them, the part of the floating slag above water is intercepted by the first telescopic plate 31, and the part underwater is intercepted by the adjacent second telescopic plate 32, the first connecting plate 33 and the second connecting plate 34. At this time, the wastewater in the outer shell 1 flows outwards through the filter holes intercepted by the first telescopic plate 31 to reduce the resistance of the first telescopic plate 31 and other parts connected thereto moving to the right.

[0028] During the process of the first telescopic plate 31 on the lower left side moving to the right, the first telescopic plate 31 drives the two adjacent hydraulic telescopic rods 41 to move to the right synchronously. The telescopic ends of the two hydraulic telescopic rods 41 drive the adjacent moving rods 42 and the U-shaped part on the left side of the adjacent limiting groove on the housing 1 to move respectively (the moving process of the rear moving rod 42 will be described as an example below). Until the moving rod 42 moves to the position where the U-shaped part on the left side of the adjacent limiting groove on the housing 1 is connected to the lower inclined part, at this time, while the moving rod 42 continues to move to the right, it is limited by the inclined part on the adjacent limiting groove and moves downward, thereby driving the telescopic ends of the adjacent hydraulic telescopic rods 41 to move downward, and pumping the hydraulic oil in the fixed parts of the adjacent first hydraulic push rod 44, the adjacent second hydraulic push rod 45, and the adjacent third hydraulic push rod 46 back to the fixed parts of the adjacent hydraulic telescopic rods 41 through the adjacent connecting pipes 43, so that the telescopic ends of the adjacent first hydraulic push rod 44, the adjacent second hydraulic push rod 45, and the adjacent third hydraulic push rod 46 move synchronously into their fixed parts.

[0029] During the process of the telescopic end of the first hydraulic push rod 44 moving into its fixed part (i.e., moving upward), the telescopic end of the first hydraulic push rod 44 drives the adjacent first connector 441 to move upward synchronously, thereby driving the adjacent second telescopic plate 32 to rotate around its connection with the first telescopic plate 31, increasing the angle between the first telescopic plate 31 and the adjacent second telescopic plate 32. Until after the second telescopic plate 32 rotates clockwise by 90° (taking Figure 2 the perspective as an example), at this time, the second telescopic plate 32 and the adjacent first telescopic plate 31 are in the same vertical plane, and the telescopic end of the first hydraulic push rod 44 does not move upward to the limit position. During the process of the telescopic end of the first hydraulic push rod 44 continuing to move upward, the telescopic end of the first hydraulic push rod 44 drives the telescopic part of the adjacent first telescopic plate 31 to move upward synchronously through the adjacent second telescopic plate 32 to shorten the length of the first telescopic plate 31. Until the moving rod 42 moves to the position where it cooperates with the U-shaped part on the right side of the adjacent limiting groove on the housing 1, the telescopic end of the first hydraulic push rod 44 and the telescopic part of the adjacent first telescopic plate 31 both move upward to the limit position synchronously.

[0030] The moving processes of the telescopic ends of the second hydraulic push rod 45 and the third hydraulic push rod 46 and the process of the front moving rod 42 moving to the right can be referred to the above.

[0031] When the moving rods 42 on the front and rear sides both move to the position where they cooperate with the U-shaped parts on the right side of the adjacent limiting grooves on the housing 1, the first telescopic plate 31, the adjacent second telescopic plate 32, the adjacent first connecting plate 33, and the adjacent second connecting plate 34 are all in the same vertical plane (the specific shape is as Figure 6As shown, at this time, the lower side of the second connecting plate 34 contacts the horizontal part on the upper side of the slag removal table 35. At this time, the floating slag intercepted by the first telescopic plate 31, the adjacent second telescopic plate 32, the adjacent first connecting plate 33, and the adjacent second connecting plate 34 is located between the first telescopic plate 31, the adjacent second telescopic plate 32, the adjacent first connecting plate 33, the adjacent second connecting plate 34, and the slag removal table 35.

[0032] When the first telescopic plate 31, the adjacent second telescopic plate 32, the adjacent first connecting plate 33, and the adjacent second connecting plate 34 continue to move to the right to contact the arc of the slag removal table 35, the moving rods 42 on the front and rear sides synchronously move to the position that matches the arc of the right U-shaped part of the adjacent limit groove on the outer shell 1. At this time, the transmission device 6 drives the first telescopic plate 31 and other parts connected thereto to rotate around the center of the arc of the slag removal table 35. During the rotation of the first telescopic plate 31 and other parts connected thereto, the second connecting plate 34 always fits the slag removal table 35. The first telescopic plate 31 and other parts connected thereto cooperate with each other to lift the intercepted floating slag. When the second connecting plate 34 rotates to the position where it contacts the upper side of the slag removal table 35, the first telescopic plate 31 and other parts connected thereto divert the intercepted floating slag, so that the intercepted floating slag flows to the space between the right side of the slag removal table 35 and the outer shell 1. At the same time, the water intercepted by the first telescopic plate 31 and other parts connected thereto flows into the outer shell 1 through the filter holes on the first telescopic plate 31, reducing the moisture content in the floating slag flowing to the space between the right side of the slag removal table 35 and the outer shell 1. The floating slag flowing to the space between the right side of the slag removal table 35 and the outer shell 1 flows out through the slag discharge port, and the fibers and other substances in the floating slag in the outer shell 1 are recycled and reused.

[0033] After discharging the scum intercepted by the first telescopic plate 31 and other parts connected thereto to the right side of the slag removal table 35 and between the outer shell 1 as described above, the transmission device 6 drives the first telescopic plate 31 and other parts connected thereto to move synchronously to the left (at this time, the first telescopic plate 31 and other parts connected thereto are located above the transmission device 6), until the moving rods 42 on the front and rear sides move to the left to the position where they are connected to the U-shaped part on the right side and the upper inclined part of the adjacent limiting groove on the outer shell 1. During the process of continuing to move to the left, the moving rods 42 on the front and rear sides are respectively limited by the inclined parts of the adjacent limiting grooves and move upward synchronously, thereby driving the telescopic ends of the adjacent hydraulic telescopic rods 41 to move upward into their fixed parts, squeezing the hydraulic oil in the fixed parts of the adjacent hydraulic telescopic rods 41 into the adjacent connecting pipes 43, and then transporting it to the fixed parts of the adjacent first hydraulic push rods 44, the fixed parts of the adjacent second hydraulic push rods 45, and the fixed parts of the adjacent third hydraulic push rods 46, so that the telescopic end of the first hydraulic push rod 44 returns to the initial state, thereby driving other parts connected thereto to return to the initial state synchronously. The movement processes of the remaining three first connecting plates 33 can be referred to the above.

[0034] During the process of the first telescopic plate 31 and other parts connected thereto returning to the initial position as described above, since the water inlet points of the first telescopic plate 31 and other parts connected thereto are located on the right side of the partition plate 5, during the process of the first telescopic plate 31 and other parts connected thereto entering the water, the scum on the left side of the partition plate 5 is not within the coverage range of the first telescopic plate 31 and other parts connected thereto. At this time, the scum on the left side of the partition plate 5 cannot be cleaned by the first telescopic plate 31 and other parts connected thereto. At the same time, when the flocculated wastewater flows between the flow guide plate 4 and the partition plate 5, the flow direction is from bottom to top. At this time, when the wastewater after air flotation flows to the right side of the partition plate 5, it is easy for some scum in the wastewater to accumulate at the junction of the right side of the flow guide plate 4 and the wastewater liquid level under the influence of the water flow, resulting in the first telescopic plate 31 and other parts connected thereto being unable to clean the scum accumulated at the junction of the right side of the flow guide plate 4 and the wastewater liquid level, thereby affecting the cleaning effect of the scum in the outer shell 1. To prevent the above situation from occurring, the following operations can be performed on this device: After the staff starts the transmission device 6 as described above, the staff starts two electric push rods 7. The telescopic ends of the two electric push rods 7 respectively drive the adjacent fixed shells 8 and other parts connected thereto to move synchronously to the right, thereby driving the moving plate 10 to move to the right. The moving plate 10 pushes the scum accumulated at the junction of the flow guide plate 4 and the wastewater liquid level to the right to a position where it can be cleaned by the first telescopic plate 31 and other parts connected thereto during the process of entering the water, ensuring the comprehensiveness of slag removal and enhancing the cleaning effect of the first telescopic plate 31 and other parts connected thereto on the scum.

[0035] During the process of the above two fixed shells 8 driving the other parts connected thereto to move synchronously to the right (taking the movement of the rear fixed shell 8 as an example for description), until the fixed shell 8 drives the adjacent fixed rod 22 to move to the right to the position where it contacts the adjacent fixed block 24, when the fixed rod 22 continues to move to the right, it is intercepted by the adjacent fixed block 24, causing the fixed rod 22 to move relatively to the left with respect to the adjacent fixed shell 8 and compressing and storing energy in the adjacent spring. The fixed rod 22 drives the adjacent pawl 23 to move synchronously. Until after the pawl 23 loses contact with the adjacent ratchet wheel 21, the torsion spring between the ratchet wheel 21 and the adjacent fixed shell 8 returns to the initial state and drives the adjacent ratchet wheel 21 to rotate clockwise. The two ratchet wheels 21 respectively drive the adjacent connecting rods 9 to rotate synchronously, and then drive the moving plate 10 to rotate synchronously, so that the moving plate 10 rotates to the horizontal state. Subsequently, the staff reversely starts the two electric push rods 7, and the electric push rods 7 drive the adjacent fixed shells 8 and the other parts connected thereto to move synchronously to the left. During this process, the two fixed rods 22 are reset to the initial positions synchronously under the action of the adjacent springs.

[0036] Until the left side surface of the moving plate 10 contacts the right side surface of the diversion plate 4, during the process of the moving plate 10 continuing to move to the left, it rotates synchronously under the limit of the diversion plate 4, so that the moving plate 10 is reset to the initial position. The moving plate 10 drives the two connecting rods 9 and the ratchet wheels 21 connected thereto to rotate synchronously, and rotates and stores energy in the adjacent torsion spring. Until when the two electric push rods 7 are both reset to the initial state, the moving plate 10 moves to the initial position synchronously. At this time, the two ratchet wheels 21 are respectively limited by the adjacent pawls 23 and cannot be reset, thereby fixing the moving plate 10. During the use of this device, the staff can start the electric push rods 7 multiple times according to the above operation process according to the content of the floating scum in the wastewater. And during the use of this device, the staff can choose to perform shutdown maintenance on this device regularly according to the usage situation of this device to extend the service life of this device.

[0037] Embodiment 2: On the basis of Embodiment 1, as Figure 2 and Figures 7-10As shown, it further includes a flow limiting mechanism. The flow limiting mechanism is used to synchronously adjust the volume of the flocculant added according to the change in the water flow rate. The flow limiting mechanism is arranged between the outer shell 1 and the deflector 4. The flow limiting mechanism includes two deflectors 51 distributed symmetrically in the front and back. Both deflectors 51 are fixedly connected between the outer shell 1 and the deflector 4 through connecting pieces. The deflectors 51 are located in the upper part of the outer shell 1. Both deflectors 51 are communicated with the water inlet pipe. A vortex fan 52 is rotatably connected inside the deflector 51. The wastewater enters the adjacent deflector 51 through the water inlet pipe, thereby driving the rotation of the adjacent vortex fan 52. The rotating shaft of the vortex fan 52 penetrates the upper side of the adjacent deflector 51. Two guide pipes 53 distributed symmetrically in the front and back are rotatably connected between the outer shell 1 and the deflector 4 through connecting pieces. Both guide pipes 53 are communicated with the medicine adding pipe. A belt and pulley drive is provided between both guide pipes 53 and the rotating shaft of the adjacent vortex fan 52. The adjacent guide pipe 53 is driven by the vortex fan 52 to rotate synchronously. A connecting ring 54 is fixedly connected to the middle of the guide pipe 53. The connecting ring 54 is provided with circumferentially uniformly distributed limiting grooves. An intercepting block 55 is slidably connected in the limiting groove of the connecting ring 54. A spring is fixedly connected between the intercepting block 55 and the adjacent connecting ring 54. When the guide pipe 53 rotates, it drives the adjacent connecting ring 54 and the adjacent intercepting block 55 to rotate synchronously, so that the intercepting block 55 moves under the action of centrifugal force into the adjacent limiting groove on the adjacent connecting ring 54. The guide pipe 53 is provided with an adjusting component, and the adjusting component is used to change the spraying range of the liquid medicine in the adjacent guide pipe 53.

[0038] As Figures 10-13As shown in the figure, the adjusting component includes a diversion housing 61. The diversion housing 61 is fixedly connected to the lower side of the adjacent diversion pipe 53. A shielding ring 62 is rotatably connected inside the diversion housing 61. The shielding ring 62 penetrates through the adjacent diversion pipe 53 and is slidably connected thereto. Through holes are uniformly distributed on the side wall, bottom surface of the diversion housing 61 and the shielding ring 62. The medicine in the diversion pipe 53 flows downward into the adjacent diversion housing 61. When the diversion pipe 53 rotates, it drives the adjacent diversion housing 61 to rotate synchronously, providing centrifugal force to the medicine flowing into the diversion housing 61, and flinging the medicine in the diversion housing 61 outward, increasing the coverage area of the medicine flowing out of the diversion housing 61. The shielding ring 62 is used to block the through holes on the side wall of the adjacent diversion housing 61. A fourth hydraulic push rod 63 is fixedly connected to the upper side of the lower part of the diversion pipe 53. The fixed part of the fourth hydraulic push rod 63 is communicated with the limiting groove of the adjacent connecting ring 54 through a connecting pipe. The limiting groove of the connecting ring 54 is filled with hydraulic oil, but the volume of the hydraulic oil in the limiting groove of the connecting ring 54 is not the maximum volume of the limiting groove on the connecting ring 54. During the movement of the intercepting block 55, the hydraulic oil in the adjacent limiting grooves on the adjacent connecting ring 54 is conveyed through the connecting pipe to the fixed part of the adjacent fourth hydraulic push rod 63. The telescopic end of the fourth hydraulic push rod 63 is in extrusion fit with the adjacent shielding ring 62. The telescopic end of the fourth hydraulic push rod 63 drives the adjacent shielding ring 62 to move. The diversion pipe 53 is rotatably connected with a connecting frame 64. An arc-shaped groove is arranged on the connecting frame 64 and is slidably matched with the telescopic end of the adjacent fourth hydraulic push rod 63. The offset distance of the arc-shaped groove on the connecting frame 64 is greater than the distance between the contact position of the telescopic end of the fourth hydraulic push rod 63 and the adjacent shielding ring 62. And the height of the arc-shaped groove on the connecting frame 64 is equal to the distance between the lower side surface inside the connecting frame 64 and the lower side surface outside the adjacent diversion housing 61. During the movement of the telescopic end of the fourth hydraulic push rod 63, it first drives the adjacent connecting frame 64 to move upward. A first limiting ring 65, a second limiting ring 66 and a third limiting ring 67 are fixedly connected to the upper side of the lower part of the connecting frame 64. The first limiting ring 65, the second limiting ring 66 and the third limiting ring 67 all penetrate through the adjacent diversion housing 61 and are in sealed sliding connection therewith. The connecting frame 64 drives the adjacent first limiting ring 65, the adjacent second limiting ring 66 and the adjacent third limiting ring 67 to move upward synchronously. The sides of the first limiting ring 65, the second limiting ring 66 and the third limiting ring 67 away from the housing 1 are all conical, and the thickness and height of the first limiting ring 65, the second limiting ring 66 and the third limiting ring 67 increase as their diameters decrease. The first limiting ring 65, the adjacent second limiting ring 66 and the adjacent third limiting ring 67 cooperate with each other to intercept the medicine flowing into the adjacent diversion housing 61.

[0039] Before delivering the wastewater and medicine into the outer shell 1, the staff connects the water inlet pipe to the two flow deflectors 51, then connects the medicine adding pipe to the two flow guide pipes 53. Subsequently, the staff conveys the wastewater into the two flow deflectors 51 through the water inlet pipe, conveys the flocculant into the front flow guide pipe 53, and conveys the coagulant aid into the rear flow guide pipe 53. The following describes the movement process of the front flow deflector 51 and the front flow guide pipe 53 as an example: During the process of the water inlet pipe conveying the wastewater into the flow deflector 51, the wastewater flows along the flow deflector 51 into the outer shell 1, and at the same time impacts the adjacent vortex fan 52, causing the adjacent vortex fan 52 to rotate. The rotating shaft of the vortex fan 52 drives the adjacent flow guide pipe 53 and other parts connected thereto to rotate synchronously through the transmission of the belt. During this process, the magnitude of the water flow velocity in the flow deflector 51 causes a difference in the rotation speed of the adjacent vortex fan 52. When the rotation speed of the vortex fan 52 is relatively high, the rotation speed of the flow guide pipe 53 is also relatively high. At this time, the centrifugal force generated by the flow guide pipe 53 is relatively large. When the centrifugal force generated by the rotation of the flow guide pipe 53 can cause the adjacent intercepting block 55 to overcome the elastic force of the adjacent spring, the intercepting block 55 slides into the adjacent limiting chute on the adjacent connecting ring 54 and compresses the adjacent spring. At this time, the flow area of the flow guide pipe 53 increases, thereby increasing the flow velocity of the medicine in the flow guide pipe 53, so that the volume of the medicine flowing out of the flow guide pipe 53 can change synchronously with the change of the water flow velocity in the flow deflector 51, avoiding the reduction of the water flow velocity in the flow deflector 51 caused by the blockage of the water inlet pipe, resulting in the wastewater flowing out of the flow deflector 51 being unable to consume the medicine flowing out of the flow guide pipe 53 in time, causing the medicine flowing out of the flow guide pipe 53 to be wasted, and causing secondary pollution to the treated wastewater.

[0040] During the process of the medicine flowing downward along the flow guide pipe 53, the medicine flowing into the flow guide pipe 53 flows downward into the interior of the adjacent flow guide shell 61 and flows out through the through holes on the adjacent flow guide shell 61. And during the rotation of the flow guide pipe 53, the flow guide pipe 53 drives the adjacent flow guide shell 61 to rotate synchronously, thereby throwing the medicine in the flow guide shell 61 outward, increasing the coverage area of the medicine in the flow guide shell 61 when flowing out, and further increasing the contact area between the wastewater and the medicine, so as to enhance the cleaning effect on the suspended matter in the wastewater.

[0041] During the process of the above-mentioned diversion pipe 53 driving the adjacent intercepting block 55 to slide into the adjacent limiting chute on the adjacent connecting ring 54, when the intercepting block 55 completely moves into the adjacent limiting chute on the adjacent connecting ring 54 (at this time, the spring between the intercepting block 55 and the adjacent connecting ring 54 is not compressed to the limit state), when the intercepting block 55 continues to move into the adjacent limiting groove on the adjacent connecting ring 54, the hydraulic oil in the limiting groove on the connecting ring 54 is extruded by the adjacent intercepting block 55 through the connecting pipe 43 into the fixed part of the adjacent fourth hydraulic push rod 63, thereby causing the telescopic end of the fourth hydraulic push rod 63 to extend outwards and driving the adjacent connecting frame 64 to move upwards. The connecting frame 64 drives the adjacent first limiting ring 65, second limiting ring 66 and third limiting ring 67 to move upwards synchronously. Until the intercepting block 55 moves to the limit position, the telescopic end of the fourth hydraulic push rod 63 moves to the limit position synchronously, and the adjacent connecting frame 64 moves upwards to the limit position synchronously. At this time, the conical parts on the upper sides of the adjacent first limiting ring 65, adjacent second limiting ring 66 and adjacent third limiting ring 67 are all located inside the adjacent diversion shell 61. The adjacent first limiting ring 65, adjacent second limiting ring 66 and adjacent third limiting ring 67 cooperate with each other to intercept the medicine flowing from the adjacent diversion pipe 53 into the adjacent diversion shell 61, avoiding that when the rotation speed of the diversion pipe 53 is too fast, the centrifugal force on the medicine inside the diversion pipe 53 is too large, resulting in too much of the medicine in the diversion shell 61 flowing outwards through the through holes on its side wall, causing the medicine thrown out by the diversion shell 61 to spread too much around, and reducing the proportion of the medicine directly below the diversion shell 61, thereby affecting the uniformity of the contact between the medicine and the wastewater and the precipitation speed of the solid impurities in the wastewater.

[0042] During the movement of the telescopic end of the above-mentioned fourth hydraulic push rod 63, when the telescopic end of the fourth hydraulic push rod 63 contacts the adjacent shielding ring 62 (at this time, the adjacent connecting frame 64 has moved upwards to the limit position), when the telescopic end of the fourth hydraulic push rod 63 continues to extend, it drives the adjacent shielding ring 62 to rotate, thereby shielding the through holes on the side wall of the adjacent diversion shell 61 by the shielding ring 62, avoiding that when the rotation speed of the diversion pipe 53 is too fast, too much of the medicine in the diversion shell 61 flows outwards through the through holes on its side wall, thereby affecting the uniformity of the contact between the medicine and the wastewater and the precipitation speed of the solid impurities in the wastewater at the same time.

[0043] When the flow velocity of the water in the flow divider 51 decreases, the rotation speed of the diversion pipe 53 decreases synchronously. At this time, the adjacent intercepting block 55 returns to the initial position under the action of the adjacent spring, thereby reducing the flow area of the diversion pipe 53 to reduce the flow volume of the medicine in the diversion pipe 53 per unit time and avoiding waste of the medicine. The specific process is opposite to the above, but still can be referred to the above.

[0044] The movement processes of the rear flow deflector 51 and the rear flow guide pipe 53 can be referred to as above. During the use of this device, the staff shall regularly perform shutdown maintenance on this device to extend the service life of this device.
