At the same time, when the connecting plate moves upward in the inner cavity of the feeding box, the connecting plate pulls the bent plate to move through the connecting block through the connecting rod, so that the bent plate moves in the slide groove through the slider, so that the bent plate moves to the middle of the connecting plate, so that the bent plate can drive the medicine accumulated on both sides of the inner cavity of the feeding box to move to the middle of the connecting plate, thereby ensuring that the sewage passing through the pipeline can be fully dosed;

[0008] Preferably, the rotating component comprises a rotating shaft, one end of the rotating shaft is rotatably connected to the water inlet component, the other end of the rotating shaft is rotatably connected to the water outlet component, a blade is fixedly connected to the middle of the rotating shaft, a notch is provided in the middle of the side surface of the blade, the blade is located below the extrusion block, both sides of the rotating shaft are fixedly connected to rotating plates, and the inner side of the rotating plate is fixedly connected to a contact mechanism; when sewage continues to pass through the pipeline, by arranging blades in the middle of the rotating shaft, the blades can drive the rotating shaft to rotate in the inner cavity of the pipeline according to the impact force of the sewage passing through the pipeline, and at the same time, the blades are in extrusion contact with the extrusion plate, so that the feeding component can perform the drug feeding work on the sewage when the sewage passes through the pipeline, and at the same time, when the rotating shaft rotates, the rotating plate is driven to rotate, so that the rotating plate impacts and stirs the drug mixed with the sewage, so that the drug and the sewage can be quickly mixed and reacted, and at the same time, when the rotating shaft drives the rotating plate to rotate, the contact mechanism is separated from the inner side of the rotating plate by the action of centrifugal force, and the contact mechanism is moved to contact the inner side of the pipeline;

The rubber plate moves against the inner wall of the pipe to avoid the inner wall of the pipe from colliding with the scraper. At the same time, when the rotating shaft rotates, the scraper can be driven by the rotating plate through the contact shaft to clean the inner wall of the pipe, thereby preventing the sludge from accumulating on the inner wall of the pipe when the sewage passes through the pipe for a long time, which will gradually reduce the effective cross-sectional area of ​​the pipe. When the sludge accumulates to a certain extent, it will hinder the normal flow of sewage and cause pipe blockage. The internal flow field of the pipe with sludge on the inner wall will be disturbed, and the mixing of sewage and chemicals will be uneven, which will cause the chemicals to fail to fully play their role, affecting the effect of sewage treatment, and failing to combine well with suspended matter in sewage, so that the suspended matter cannot be effectively precipitated, increasing the difficulty of subsequent treatment;

[0010] Preferably, the water inlet component includes a water inlet shell, the side of the water inlet shell is fixedly connected to the pipeline, the side of the water inlet shell is fixedly connected to a mesh plate, the side of the mesh plate is fixedly connected to a telescopic rod, the end of the telescopic rod away from the mesh plate is fixedly connected to a connecting frame, a third spring is sleeved on the telescopic rod, one end of the third spring is fixedly connected to the connecting frame, the other end of the third spring is fixedly connected to the mesh plate, the side of the connecting frame close to the mesh plate is fixedly connected to an ejection mechanism, and the ejection mechanism is concentrically arranged with the mesh of the mesh plate; when one end of the sewage pipe is fixedly connected to the water inlet shell, the sewage in the sewage pipe is simultaneously Entering into the water inlet housing, a mesh plate is arranged on the side of the water inlet housing to filter the sewage entering into the water inlet housing, thereby preventing large particles of impurities mixed in the sewage from entering the pipeline, and at the same time, the impact force of the sewage drives the connecting frame to drive the ejection mechanism to separate from the mesh plate through the telescopic rod. At the same time, when the mesh holes on the mesh plate are blocked, the impact force of the sewage passing through the mesh plate is less than the tensile force of the third spring, so that the third spring drives the ejection mechanism to move toward the mesh plate through the connecting frame, so that the ejection mechanism ejects the impurities stuck in the mesh plate, thereby ensuring that the mesh plate can perform normal filtering and blocking work;

[0011] Preferably, the ejection mechanism comprises an ejection rod, wherein one end of the ejection rod away from the ejector pin is fixedly connected to a side of the connecting frame close to the mesh plate, a notch is provided on the side of the ejection rod, a cylinder is slidably connected to the inner side of the notch, the side of the cylinder is fixedly connected to a sliding rod, the side of the sliding rod is slidably connected to the inner side of the ejection rod, the end of the sliding rod away from the cylinder is fixedly connected to the ejector pin, a fourth spring is sleeved on the sliding rod, one end of the fourth spring is fixedly connected to the ejector pin, and the other end of the fourth spring is fixedly connected to the ejection rod, the side of the cylinder away from the sliding rod is fixedly connected to a connecting sleeve, and the side of the connecting sleeve away from the ejector pin is fixedly connected to an arc plate; when the mesh holes on the mesh plate are clogged, the impact force of sewage passing through the mesh plate is less than the tensile force of the third spring, so that the third spring drives the ejection rod to move toward the mesh plate through the connecting frame, so that the ejection rod drives The ejector pin ejects the impurities stuck in the mesh of the mesh plate.

At the same time, when the ejector pin continues to move in the mesh through the tension of the third spring, the arc plate can be driven by the connecting sleeve to contact and clean the inner wall of the mesh, thereby preventing the sludge in the sewage from remaining on the inner wall of the mesh when the sewage passes through the mesh plate, thereby adhering to and accumulating in the mesh, thereby causing the mesh to be blocked.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present invention provides a feeding component, and adds medicine into the feeding box through the feeding port. When sewage enters the pipeline through the pipeline, the rotating component is driven by the impact force of the sewage to rotate in the pipeline, so that the rotating component rotates in the inner cavity of the pipeline, so that the rotating component and the extrusion plate are extruded. The extrusion plate is subjected to the extrusion force, so that the extrusion plate drives the connecting plate to move upward in the inner cavity of the feeding box through the extrusion shaft, so that the connecting plate is driven by the connecting shaft, and the baffle and the block move in the inner cavity of the feeding box, so that the block is separated from the bottom of the inner cavity of the feeding box, so that the medicine in the feeding box flows out through the gap formed by the block and the bottom of the inner cavity of the feeding box, and is mixed with the sewage entering the pipeline.

[0014] 2. The present invention sets a rotating component. When sewage continues to pass through the pipeline, blades are set in the middle of the rotating shaft. Therefore, according to the impact force of the sewage passing through the pipeline, the blades can drive the rotating shaft to rotate in the inner cavity of the pipeline. At the same time, the blades are squeezed and contacted with the extrusion plate, so that the feeding component can feed the sewage with the medicine when the sewage passes through the pipeline. At the same time, when the rotating shaft rotates, the rotating plate is driven to rotate, so that the rotating plate impacts and stirs the medicine mixed with the sewage, so that the medicine and the sewage can be quickly mixed and reacted. At the same time, when the rotating shaft drives the rotating plate to rotate, the contact mechanism is separated from the inner side of the rotating plate by the action of centrifugal force, and moves to contact the inner side of the pipeline.

[0015] 3. The present invention provides a contact mechanism. When the rotating plate rotates following the rotating shaft, the contact shaft drives the contact plate to move toward the inner side of the pipe through the action of centrifugal force. At the same time, a rubber plate is provided on the side of the contact plate to avoid the contact shaft driving the rubber plate to collide and move toward the inner wall of the pipe through the action of centrifugal force, thereby avoiding the inner wall of the pipe from colliding with the scraper. At the same time, when the rotating shaft rotates, the scraper can be driven by the rotating plate through the contact shaft to clean the inner wall of the pipe, thereby avoiding the continuous accumulation of sludge on the inner wall of the pipe when the sewage passes through the pipe for a long time, which will gradually reduce the effective cross-sectional area of ​​the pipe. When the sludge accumulates to a certain extent, it will hinder the normal flow of sewage and cause the pipe to be blocked. The internal flow field of the pipe with sludge on the inner wall will be disturbed, and the mixing of sewage and the agent will be uneven, which will cause the agent to fail to fully play its role, affecting the effect of sewage treatment, and failing to combine well with the suspended matter in the sewage, so that the suspended matter cannot be effectively precipitated, increasing the difficulty of subsequent treatment.

[0016] 4. The present invention provides a water inlet component, when one end of the sewage pipe is fixedly connected to the water inlet shell, the sewage in the sewage pipe enters the water inlet shell, and a mesh plate is provided on the side of the water inlet shell, so that the sewage entering the water inlet shell is filtered, thereby preventing large particles of impurities mixed in the sewage from entering the pipe, and at the same time, through the impact force of the sewage, the connecting frame drives the ejection mechanism to detach from the mesh plate through the telescopic rod. At the same time, when the mesh holes on the mesh plate are blocked, the impact force of the sewage passing through the mesh plate is less than the tensile force of the third spring, so that the third spring drives the ejection mechanism to move toward the mesh plate through the connecting frame, so that the ejection mechanism ejects the impurities stuck in the mesh plate, thereby ensuring that the mesh plate can perform normal filtering and blocking work.

[0032] Example 2, using Figure 5-Figure 6 The following is a description of a dosing device for sewage treatment with controllable dosage of the drug according to the present invention;

[0033] like Figure 5-Figure 6It is shown that a dosing device for sewage treatment with controllable dosage of the present invention is based on the first embodiment;

[0034] The rotating component 5 includes a rotating shaft 51, one end of which is rotatably connected to the water inlet component 4, and the other end of which is rotatably connected to the water outlet component 3. A blade 52 is fixedly connected to the middle of the rotating shaft 51, and a notch is provided in the middle of the side of the blade 52. The blade 52 is located below the extrusion block. Rotating plates 53 are fixedly connected to both sides of the rotating shaft 51, and a contact mechanism 54 is fixedly connected to the inner side of the rotating plate 53. When sewage continues to pass through the pipe 1, the blade 52 is provided in the middle of the rotating shaft 51, so that the blade 52 can drive the rotating shaft 51 to move in the pipe 1 according to the impact force of the sewage passing through the pipe 1. The rotating plate 53 is rotated in the inner cavity, and the blade 52 is squeezed and contacted with the squeezing plate 23, so that the feeding component 2 can feed the medicine into the sewage when the sewage passes through the pipe 1. At the same time, when the rotating shaft 51 rotates, the rotating plate 53 is driven to rotate, so that the rotating plate 53 impacts and stirs the medicine mixed with the sewage, so that the medicine and the sewage can be quickly mixed and reacted. At the same time, when the rotating shaft 51 drives the rotating plate 53 to rotate, the contact mechanism 54 is separated from the inner side of the rotating plate 53 by the action of centrifugal force, and moves in contact with the inner side of the pipe 1;

[0035] The contact mechanism 54 includes a contact shaft 541, the side of which is slidably connected to the inner side of the rotating plate 53, the end of the contact shaft 541 away from the inner side of the rotating plate 53 is fixedly connected to a contact plate 542, the side of the contact plate 542 is fixedly connected to a rubber plate 543, and the side of the contact plate 542 away from the rubber plate 543 is fixedly connected to a scraper 544, and a second spring 545 is sleeved on the contact shaft 541, one end of the second spring 545 is fixedly connected to the contact plate 542, and the other end of the second spring 545 is fixedly connected to the inner side of the contact plate 542; when the rotating plate 53 rotates following the rotating shaft 51, the contact shaft 541 drives the contact plate 542 to move toward the inner side of the pipe 1 through the action of centrifugal force, and at the same time, the rubber plate 543 is provided on the side of the contact plate 542, so as to avoid the contact shaft 541 being moved by centrifugal force The contact plate 542 drives the rubber plate 543 to move toward the inner wall of the pipe 1 to impact, thereby preventing the inner wall of the pipe 1 from colliding with the scraper 544. At the same time, when the rotating shaft 51 rotates, the scraper 544 can be driven by the rotating plate 53 through the contact shaft 541 to clean the inner wall of the pipe 1, thereby preventing the sewage from passing through the pipe 1 for a long time. The sludge will continue to accumulate on the inner wall of the pipe 1, which will gradually reduce the effective cross-sectional area of ​​the pipe 1. When the sludge accumulates to a certain extent, it will hinder the normal flow of sewage and cause the pipe 1 to be blocked. The pipe 1 with sludge on the inner wall will have its internal flow field disturbed, and the sewage and the agent will be unevenly mixed, which will cause the agent to fail to fully play its role, affecting the effect of sewage treatment, and failing to combine well with the suspended matter in the sewage, so that the suspended matter cannot be effectively precipitated, increasing the difficulty of subsequent treatment;

[0036] Example 3, using Figure 7-Figure 8 The following is a description of a dosing device for sewage treatment with controllable dosage of the drug according to the present invention;

[0037] like Figure 7-Figure 8 It is shown that a dosing device for sewage treatment with controllable dosage of the present invention is based on the first embodiment;

[0038] The water inlet component 4 includes a water inlet housing 41, the side of the water inlet housing 41 is fixedly connected to the pipeline 1, the side of the water inlet housing 41 is fixedly connected to a mesh plate 42, the side of the mesh plate 42 is fixedly connected to a telescopic rod 43, the end of the telescopic rod 43 away from the mesh plate 42 is fixedly connected to a connecting frame 44, a third spring 45 is sleeved on the telescopic rod 43, one end of the third spring 45 is fixedly connected to the connecting frame 44, the other end of the third spring 45 is fixedly connected to the mesh plate 42, and the side of the connecting frame 44 close to the mesh plate 42 is fixedly connected to an ejection mechanism 46, and the ejection mechanism 46 is concentrically arranged with the mesh of the mesh plate 42; when one end of the sewage pipe is fixedly connected to the water inlet housing 41, the sewage in the sewage pipe enters the water inlet housing 4 at the same time. 1, a mesh plate 42 is provided on the side of the water inlet housing 41, so that the sewage entering the water inlet housing 41 is filtered, thereby preventing large particles of impurities mixed in the sewage from entering the pipe 1, and at the same time, the impact force of the sewage drives the connecting frame 44 to drive the ejection mechanism 46 to separate from the mesh plate 42 through the telescopic rod 43. At the same time, when the mesh holes on the mesh plate 42 are blocked, the impact force of the sewage passing through the mesh plate 42 is less than the tensile force of the third spring 45, so that the third spring 45 drives the ejection mechanism 46 to move toward the mesh plate 42 through the connecting frame 44, so that the ejection mechanism 46 ejects the impurities stuck in the mesh plate 42, thereby ensuring that the mesh plate 42 can perform normal filtering and blocking work;

[0039] The ejection mechanism 46 includes an ejection rod 461, one end of the ejection rod 461 away from the ejector pin 465 is fixedly connected to the side of the connecting frame 44 close to the mesh plate 42, a slot 462 is provided on the side of the ejection rod 461, a cylinder 463 is slidably connected to the inner side of the slot 462, a sliding rod 464 is fixedly connected to the side of the cylinder 463, the side of the sliding rod 464 is slidably connected to the inner side of the ejection rod 461, the end of the sliding rod 464 away from the cylinder 463 is fixedly connected to the ejector pin 465, and a fourth spring 466 is sleeved on the sliding rod 464. One end of the fourth spring 466 is fixedly connected to the ejector pin 465, and the other end of the fourth spring 466 is fixedly connected to the ejector rod 461. A connecting sleeve 467 is fixedly connected to the side of the cylinder 463 away from the sliding rod 464, and an arc plate 468 is fixedly connected to the side of the connecting sleeve 467 away from the ejector pin 465. When the mesh holes on the mesh plate 42 are clogged, the impact force of the sewage passing through the mesh plate 42 is less than the tensile force of the third spring 45, so that the third spring 45 drives the ejector rod 461 to move toward the mesh plate 42 through the connecting frame 44. Thus, the ejection rod 461 drives the ejector pin 465 to eject the impurities blocked in the mesh of the mesh plate 42. At the same time, when the extrusion force between the ejector pin 465 and the impurities blocked in the mesh of the mesh plate 42 is greater than the tensile force of the fourth spring 466, the sliding rod 464 slides in the slot 462 through the slider 29, thereby driving the ejector pin 465 to move backward. At the same time, the buffering force of the fourth spring 466 is used to prevent the extrusion force between the ejector pin 465 and the impurities blocked in the mesh of the mesh plate 42 from being too large, thereby causing the ejector pin 465 to be pressed against the mesh of the mesh plate 42. 5 causes extrusion damage, thereby causing extrusion wear on the inner wall of the mesh, thereby causing friction damage to the inner wall of the mesh of the mesh plate 42, thereby causing the mesh to expand. At the same time, when the ejector rod 461 is driven by the stretching of the third spring 45 to continue to move in the mesh, the arc plate 468 can be driven by the connecting sleeve 467 to contact and clean the inner wall of the mesh, thereby preventing the sludge in the sewage from remaining on the inner wall of the mesh when the sewage passes through the mesh plate 42, thereby adhering to and accumulating in the mesh, thereby causing the mesh to be blocked;

[0040] The specific workflow is as follows:

[0041] When working, one end of the sewage pipe is fixed to the water inlet component 4, so that the sewage enters the pipe 1. At the same time, the impact force of the sewage causes the feeding component 2 to perform quantitative medicine feeding according to the speed at which the sewage passes. At the same time, the impact force of the sewage passing through the pipe 1 drives the rotating component 5 to rotate in the pipe 1, so that the medicine and the sewage are evenly mixed. The sewage mixed with the medicine flows out through the water outlet component 3, so that the sewage mixed with the medicine is subsequently treated.

[0042] When one end of the sewage pipe is fixedly connected to the water inlet housing 41, the sewage in the sewage pipe enters the water inlet housing 41. At the same time, a mesh plate 42 is arranged on the side of the water inlet housing 41, so that the sewage entering the water inlet housing 41 is filtered, thereby preventing large particles of impurities mixed in the sewage from entering the pipe 1. At the same time, the impact force of the sewage drives the connecting frame 44 to drive the ejection mechanism 46 to detach from the mesh plate 42 through the telescopic rod 43. At the same time, when the mesh holes on the mesh plate 42 are blocked, the impact force of the sewage passing through the mesh plate 42 is less than the tensile force of the third spring 45, so that the third spring 45 drives the ejection mechanism 46 to move toward the mesh plate 42 through the connecting frame 44, so that the ejection mechanism 46 ejects the impurities stuck in the mesh plate 42, thereby ensuring that the mesh plate 42 can perform normal filtering and blocking work;

[0043] When the mesh holes on the mesh plate 42 are clogged, the impact force of the sewage passing through the mesh plate 42 is less than the tensile force of the third spring 45, so that the third spring 45 drives the ejection rod 461 to move toward the mesh plate 42 through the connecting frame 44, so that the ejection rod 461 drives the ejector pin 465 to eject the impurities blocked in the mesh holes of the mesh plate 42. At the same time, when the extrusion force between the ejector pin 465 and the impurities blocked in the mesh holes of the mesh plate 42 is greater than the tensile force of the fourth spring 466, the sliding rod 464 slides in the slot 462 through the slider 29, thereby driving the ejector pin 465 to move backward. At the same time, through the buffering force of the fourth spring 466, This prevents the extrusion force between the ejector pin 465 and the impurities blocked in the mesh of the mesh plate 42 from being too large, which would cause extrusion damage to the ejector pin 465, which would cause extrusion wear to the inner wall of the mesh, which would cause friction damage to the inner wall of the mesh of the mesh plate 42, which would cause the mesh to expand. At the same time, when the ejector rod 461 is driven by the stretching of the third spring 45 to continue to move in the mesh, the arc plate 468 can be driven by the connecting sleeve 467 to contact and clean the inner wall of the mesh, thereby preventing the sludge in the sewage from remaining on the inner wall of the mesh when the sewage passes through the mesh plate 42, and then adhering to and accumulating in the mesh, thereby causing the mesh to be blocked.

[0044] The medicine is added to the feeding box 21 through the feeding port 22. When the sewage enters the pipe 1 through the pipe 1, the rotating component 5 is driven by the impact force of the sewage to rotate in the pipe 1, so that the rotating component 5 rotates in the inner cavity of the pipe 1, so that the rotating component 5 and the extrusion plate 23 are squeezed, and the extrusion plate 23 is subjected to the extrusion force, so that the extrusion plate 23 drives the connecting plate 211 to move upward in the inner cavity of the feeding box 21 through the extrusion shaft 24, so that the connecting plate 211 is driven by the connecting shaft 212, and the baffle 213 and the stopper 214 move in the inner cavity of the feeding box 21, so that the stopper 214 is separated from the bottom of the inner cavity of the feeding box 21, so that the feeding box 21 is The medicine in the feed box 21 flows out through the gap formed by the stopper 214 and the bottom of the inner cavity of the feed box 21, thereby mixing with the sewage entering the pipe 1. At the same time, when the connecting plate 211 moves upward in the inner cavity of the feed box 21, the connecting plate 211 pulls the bent plate 27 to move through the connecting block 28 through the connecting rod 26, so that the bent plate 27 moves in the slide groove 210 through the slider 29, so that the bent plate 27 moves to the middle of the connecting plate 211, so that the bent plate 27 can drive the medicine accumulated on both sides of the inner cavity of the feed box 21 to move to the middle of the connecting plate 211, thereby ensuring that the sewage passing through the pipe 1 can be fully dosed;

[0045] When sewage continues to pass through the pipe 1, a blade 52 is provided in the middle of the rotating shaft 51, so that according to the impact force of the sewage passing through the pipe 1, the blade 52 can drive the rotating shaft 51 to rotate in the inner cavity of the pipe 1, and at the same time, the notch of the blade 52 is squeezed and contacted with the extrusion plate 23, so that the feeding component 2 can perform the medicine feeding work on the sewage when the sewage passes through the pipe 1, and at the same time, when the rotating shaft 51 rotates, the rotating plate 53 is driven to rotate, so that the rotating plate 53 impacts and stirs the medicine mixed with the sewage, so that the medicine and the sewage can be quickly mixed and reacted, and at the same time, when the rotating shaft 51 drives the rotating plate 53 to rotate, the contact mechanism 54 is separated from the inner side of the rotating plate 53 by the action of centrifugal force, and moves in contact with the inner side of the pipe 1;

[0046] When the rotating plate 53 rotates following the rotating shaft 51, the contact shaft 541 drives the contact plate 542 to move toward the inner side of the pipe 1 through the action of centrifugal force. At the same time, a rubber plate 543 is provided on the side of the contact plate 542 to prevent the contact shaft 541 from driving the rubber plate 543 to collide with the inner wall of the pipe 1 through the contact plate 542 through the action of centrifugal force, thereby preventing the inner wall of the pipe 1 from colliding with the scraper 544. At the same time, when the rotating shaft 51 rotates, the scraper 544 can be driven by the rotating plate 53 through the contact shaft 541. 544 The inner wall of pipe 1 is cleaned to prevent sludge from accumulating on the inner wall of pipe 1 when sewage passes through pipe 1 for a long time, which will gradually reduce the effective cross-sectional area of ​​pipe 1. When the sludge accumulates to a certain extent, it will hinder the normal flow of sewage and cause pipe 1 to be blocked. The internal flow field of pipe 1 with sludge on the inner wall will be disturbed, and the sewage and the agent will be mixed unevenly, which will cause the agent to fail to fully play its role, affecting the effect of sewage treatment, and failing to combine well with suspended matter in sewage, making it impossible for the suspended matter to be effectively precipitated, increasing the difficulty of subsequent treatment.
