Technical Field
[0001] This invention belongs to the field of agricultural non-point source pollution control technology, and particularly relates to an agricultural non-point source pollution control device and method. Background Technology
[0002] Agricultural non-point source pollution refers to the large-scale entry of dissolved or solid pollutants into receiving water bodies by rainwater and runoff through surface runoff, farmland drainage, and groundwater infiltration during agricultural production and daily life. If the wastewater is not treated in a timely manner, it will have a significant impact on our living environment and seriously endanger our health. Therefore, the proper treatment of wastewater is of paramount importance.
[0003] Currently, common wastewater treatment methods typically involve directly pouring wastewater into a sedimentation tank, then manually adding flocculants to coagulate and separate impurities from the wastewater, thus achieving the purpose of wastewater treatment.
[0004] However, wastewater settling tanks are often quite large, and manual application cannot effectively distribute the flocculant evenly throughout the settling tank. Summary of the Invention

A plurality of first gears are meshed on the first toothed plate, and the plurality of first gears correspond one-to-one with a plurality of shafts. One end of each shaft extends out of the spray cylinder and is fixedly connected to the first gear. A reset cylinder is sleeved on the end of the first toothed plate away from the second protrusion, and a reset spring is fixedly connected between the inner end wall of the reset cylinder and the first toothed plate.
[0011] Optionally, a material-dispensing cylinder is fixedly connected and communicates with the flocculation cylinder and the volatilization cylinder. A first transmission rod is rotatably connected between several material-dispensing cylinders. Several sets of material-dispensing blades are fixedly connected to the first transmission rod. Each set of material-dispensing blades is located inside one of the several material-dispensing cylinders, and the end of each material-dispensing blade away from the first transmission rod abuts against the inner wall of the material-dispensing cylinder. A second gear is fixedly connected to one end of the first transmission rod. The second gear is meshed with a second toothed plate. The second toothed plate is fixedly connected to the side wall of the sedimentation tank and is parallel to the moving direction of the moving plate.
[0012] Optionally, a support plate is fixedly connected inside the spray cylinder, the support plate is located above the shaft, and two guide plates are fixedly connected to both sides of the support plate. The two guide plates are located at both ends of the support plate and contact the inner wall of the spray cylinder. A rotating rod is rotatably connected between the two guide plates by a spiral spring. A sliding rod is provided on the side of the rotating rod away from the support plate. The sliding rod is slidably connected between the two guide plates. An intercepting cloth is wound around the rotating rod. The end of the intercepting cloth away from the rotating rod is fixedly connected to the sliding rod. One end of a pull rope is fixedly connected to the sliding rod. The other ends of the two pull ropes away from the sliding rod are fixedly connected to both sides of the bottom end of the spray plate by guide components.
[0013] Optionally, the guide assembly includes an L-shaped channel, which is formed inside the side wall of the spray cylinder.

[0014] Optionally, the top surface of the support plate is higher than the guide plate, and a partition plate is fixedly connected to the top surface of the support plate. The two side walls of the partition plate are inclined surfaces that slope downward away from the center of the support plate.
[0015] Optionally, the drive assembly includes a motor, which is fixedly connected to one end of the top opening of the sedimentation tank. The output shaft of the motor is provided with a lead screw, which passes through the movable plate and is threadedly connected to the movable plate.

[0020] Step 2: Start the motor, move the moving plate, use the feeding blades to feed the material, and use the scattering plate to spread the material.
[0021] Step 3: After the flocculant has finished adsorbing, the wastewater is discharged.
[0022] Compared with the prior art, the present invention has the following advantages and technical effects:
[0023] By adding wastewater into a sedimentation tank and then adding flocculant, the flocculant is first introduced into several flocculation cylinders. A drive assembly then moves a moving plate along the inner cavity of the sedimentation tank. During this movement, the second protrusion continuously contacts several first protrusions, causing a reciprocating assembly to reciprocate the shaft. This keeps the shaft rotating, which in turn causes the spraying plates to flip left and right, thus spraying the flocculant flowing from the flocculation cylinders to the spraying cylinders. This left-right spraying of flocculant by the spraying plates, combined with the drive assembly moving the moving plate along the inner cavity of the sedimentation tank, frees up manual labor and improves the uniformity of flocculant addition within the sedimentation tank, thereby enhancing wastewater treatment efficiency.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0036] Reference Figure 1-8 As shown, this embodiment provides an agricultural non-point source pollution control device, including:
[0037] Settling tank 1, with a drive assembly at the top of settling tank 1, and a moving plate 2 connected to the drive assembly. The moving plate 2 moves horizontally along the length of the inner cavity of settling tank 1. Several flocculation cylinders 3 are fixedly connected to the moving plate 2, and the bottom opening of the flocculation cylinders 3 is connected to the inner cavity of settling tank 1.
[0038] A number of volatilization cylinders 4 are provided, each corresponding to a number of flocculation cylinders 3. The volatilization cylinders 4 are located below the flocculation cylinders 3 and are connected to the flocculation cylinders 3. A shaft 5 is rotatably connected inside the volatilization cylinder 4, and a volatilization plate 6 is fixedly connected to the shaft 5.
[0039] A number of first protrusions 7 are fixedly connected at equal intervals to the inner wall of the sedimentation tank 1 and are parallel to the moving direction of the moving plate 2. A second protrusion 8 is detachably connected between the first protrusions 7. A reciprocating component is fixedly connected to the end of the second protrusion 8 away from the first protrusion 7. The reciprocating component is located below the moving plate 2 and is connected to a number of shafts 5 for transmission.
[0040] By adding sewage into the sedimentation tank 1, when adding flocculant, the flocculant is first introduced into several flocculation cylinders 3. Then, the moving plate 2 is driven to move horizontally along the inner cavity of the sedimentation tank 1 by the drive component. During the horizontal movement of the moving plate 2, the second protrusion 8 and several first protrusions 7 are in continuous contact, which drives the reciprocating component to reciprocate the shaft 5, so that the shaft 5 keeps reciprocating. Then, the reciprocating rotation of the shaft 5 drives the evaporation plate 6 to flip left and right, thereby evaporating the flocculant flowing from the flocculation cylinder 3 to the evaporation cylinder 4.
[0041] The reciprocating assembly further optimizes the design by including a first toothed plate 9, which is fixedly connected to a second protrusion 8. Several first gears 10 are meshed on the first toothed plate 9, and the several first gears 10 correspond one-to-one with several shafts 5. One end of the shaft 5 extends out of the spray cylinder 4 and is fixedly connected to the first gear 10. A reset cylinder 11 is sleeved on the end of the first toothed plate 9 away from the second protrusion 8. A reset spring 12 is fixedly connected between the inner end wall of the reset cylinder 11 and the first toothed plate 9.
[0042] During the translation of the moving plate 2, the first toothed plate 9 moves synchronously. The continuous contact between the first protrusions 7 and the second protrusions 8 causes the first toothed plate 9 to be displaced. The first toothed plate 9 is automatically reset by the reset cylinder 11 and the reset spring 12. Thus, when the moving plate 2 moves, the first toothed plate 9 automatically performs reciprocating motion, thereby driving the first gears 10 to rotate reciprocally. This causes the shaft 5 to drive the spray plate 6 to flip left and right.
[0043] Furthermore, a first support rod 33 is fixedly connected to the reset cylinder 11, and the first support rod 33 is fixedly connected to the bottom surface of the moving plate 2. A guide cylinder 34 is sleeved on the outer wall of the first toothed plate 9. The guide cylinder 34 is fixedly connected to the bottom surface of the moving plate 2 through a second support rod 35. The first support rod 33 and the second support rod 35 are used to fix the position of the reset cylinder 11 and the guide cylinder 34, thereby fixing the position of the first toothed plate 9.
[0044] In a further optimized scheme, a material feeding cylinder 13 is fixedly connected and connected between the flocculation cylinder 3 and the volatilization cylinder 4. A first transmission rod 14 is rotatably connected between several material feeding cylinders 13. Several sets of material feeding blades 15 are fixedly connected to the first transmission rod 14. The several sets of material feeding blades 15 are located inside several material feeding cylinders 13, and the end of the material feeding blade 15 away from the first transmission rod 14 abuts against the inner wall of the material feeding cylinder 13. A second gear 16 is fixedly connected to one end of the first transmission rod 14. The second gear 16 is meshed with a second toothed plate 17. The second toothed plate 17 is fixedly connected to the side wall of the sedimentation tank 1 and is parallel to the moving direction of the moving plate 2.
[0045] As the moving plate 2 moves horizontally, the second gear 16 at one end of the first transmission rod 14 meshes with the second toothed plate 17, causing the first transmission rod 14 to rotate. This, in turn, drives several sets of material-distributing blades 15 to rotate, thereby distributing the flocculant in the flocculation cylinder 3 to the volatilization cylinder 4. Each set of material-distributing blades 15 preferably consists of 5 blades, which are fixed at equal intervals to the side wall of the first transmission rod 14. When the first transmission rod 14 stops rotating, the material-distributing blades 15 stop moving, thus intercepting the flocculant in the distributing cylinder 13 and preventing flocculant leakage when the device stops.
[0046] In a further optimized design, a support plate 18 is fixedly connected inside the spray cylinder 4. The support plate 18 is located above the shaft 5. Two guide plates 19 are fixedly connected to both sides of the support plate 18. The two guide plates 19 are located at both ends of the support plate 18 and are in contact with the inner wall of the spray cylinder 4 (to improve sealing). A rotating rod 21 is rotatably connected between the two guide plates 19 through a spiral spring 20. A sliding rod 22 is provided on the side of the rotating rod 21 away from the support plate 18. The sliding rod 22 is slidably connected between the two guide plates 19. An intercepting cloth 23 is wound around the rotating rod 21. The end of the intercepting cloth 23 away from the rotating rod 21 is fixedly connected to the sliding rod 22. One end of a pull rope 24 is fixedly connected to the sliding rod 22. The other ends of the two pull ropes 24 away from the sliding rod 22 are fixedly connected to both sides of the bottom end of the spray plate 6 through guide components.
[0047] When the spray plate 6 flips left and right, for example, to the left, the pull rope 24 on the right side of the spray plate 6 drives the slide rod 22 to slide away from the rotating rod 21, thereby extending the intercepting cloth 23, which can close the space on that side, preventing a large amount of flocculant from flowing out and reducing the waste of flocculant. At the same time, the spiral spring 20 on the left side loses its tension and drives the rotating rod 21 to rotate, which rolls up the intercepting cloth 23 on that side, so that the flocculant on that side flows onto the spray plate 6.
[0048] Furthermore, sliding grooves 36 are respectively provided on the opposite end faces of the two guide plates 19, and the two ends of the slide rod 22 are slidably connected in the sliding grooves 36.
[0049] The scheme is further optimized. The guide component includes an L-shaped channel 25, which is opened inside the side wall of the spray cylinder 4. The horizontal end of the L-shaped channel 25 is connected to the inner cavity of the spray cylinder 4, and the vertical end of the L-shaped channel 25 is connected to the outside. A guide wheel 26 is provided at the bottom of the vertical end of the L-shaped channel 25. The pull rope 24 extends into the L-shaped channel 25 and is tensioned by the guide wheel 26.
[0050] The L-shaped channel 25 and guide wheel 26 guide the pull rope 24, thereby improving the transmission effect of the pull rope 24.
[0051] In a further optimized design, the top surface of the support plate 18 is higher than that of the guide plate 19, and a partition plate 27 is fixedly connected to the top surface of the support plate 18. The two side walls of the partition plate 27 are inclined surfaces that slope downward away from the center of the support plate 18.
[0052] By setting the partition plate 27, the flocculant can be separated to both sides of the support plate 18 to avoid accumulation on the support plate 18. Furthermore, both ends of the bottom surface of the partition plate 27 extend beyond the two rotating rods 21 to improve the flow effect of the flocculant.
[0053] Further optimization of the scheme: the drive component includes a motor 28, which is fixedly connected to one end of the top opening of the sedimentation tank 1. The output shaft of the motor 28 is provided with a lead screw 29, which passes through the movable plate 2 and is threadedly connected to the movable plate 2. Guide rods 30 parallel to the lead screw 29 are provided on both sides of the lead screw 29. The guide rods 30 are fixedly connected to the top of the sedimentation tank 1 and pass through the movable plate 2 and are slidably connected to the movable plate 2.
[0054] The movable plate 2 can be moved horizontally by the motor 28 driving the lead screw 29 to rotate and guided and limited by the two guide rods 30. By controlling the forward and reverse rotation of the motor 28, the movable plate 2 can be moved back and forth on the sedimentation tank 1.
[0055] To further optimize the design, an inlet pipe 31 is fixedly connected to the side wall of sedimentation tank 1, which communicates with its inner cavity.
[0056] Wastewater is added into sedimentation tank 1 through inlet pipe 31.
[0057] To further optimize the design, a liquid outlet pipe 32 is fixedly connected to the side wall of sedimentation tank 1, which communicates with its inner cavity.
[0058] The treated wastewater is discharged into the sedimentation tank 1 through the outlet pipe 32.
[0059] Valves are installed on both the inlet pipe 31 and the outlet pipe 32.
[0060] Furthermore, to improve the mixing effect of the flocculant, a second transmission rod 37 is rotatably connected to the end of the moving plate 2 away from the second toothed plate 17. A third gear 38 is fixedly connected to the end of the second transmission rod 37 away from the moving plate 2. The third gear 38 meshes with a third toothed plate 39, which is fixed to the inner wall of the settling tank 1 and parallel to the translational direction of the moving plate 2. A cam 40 is fixedly connected to the second transmission rod 37, and the cam 40 abuts against a connecting rod 41. A support rod 42 is fixedly connected to the side wall of the connecting rod 41, and the end of the moving plate 2 corresponding to the support rod 42 is... A limiting groove 43 is formed on the surface, and a limiting rod 44 is fixedly connected in the limiting groove 43. The end of the support rod 42 away from the connecting rod 41 extends into the limiting groove 43 and is slidably connected to the limiting rod 44. A limiting spring 45 is fitted on the limiting rod 44 and is fixed between the support rod 42 and the bottom surface of the limiting groove 43. The end of the connecting rod 41 away from the cam 40 is rotatably connected to a third transmission rod 46. The third transmission rod 46 is perpendicular to the connecting rod 41 and is located in the inner cavity of the sedimentation tank 1. Several stirring blades 47 are fixedly connected to the third transmission rod 46.
[0061] With this configuration, when the moving plate 2 moves horizontally, the meshing of the third gear 38 and the third toothed plate 39 causes the second transmission rod 37 to rotate, thereby causing the cam 40 to rotate. This causes the cam 40 to drive the connecting rod 41 to move up and down reciprocally. The limiting groove 43, the limiting rod 44, and the limiting spring 45 are used to guide and reset the support rod 42, thereby driving the third transmission rod 46 to move up and down in the sewage. As the moving plate 2 moves horizontally, the water flow causes the third transmission rod 46 to rotate, causing the stirring blades 47 to mix and stir the sewage and flocculant, improving the mixing effect of the flocculant and sewage.
[0062] A method for controlling agricultural non-point source pollution includes the following steps:
[0063] Step 1: Add wastewater through inlet pipe 31, and at the same time add flocculant into flocculation cylinder 3;
[0064] Step 2: Start the motor 28, which drives the moving plate 2 to move through the lead screw 29. The second gear 16 on the first transmission rod 14 rotates along the second tooth plate 17, thereby driving several material-dispensing blades 15 to dispense material. At the same time, through the continuous contact between the second protrusion 8 and several first protrusions 7, the first tooth plate 9 drives several first gears 10 to rotate back and forth, thereby driving several evaporation plates 6 to scatter material left and right.
[0065] Step 3: After the flocculant adsorption is complete, the wastewater is discharged through the outlet pipe 32.
