Description

Technical Field

[0001] The present invention relates to the field of wastewater treatment, and in particular to an intelligent conditioning and purification device for biological fertilizer production wastewater. Background Art

[0002] During the production process of biological fertilizers, a large amount of high-concentration organic wastewater is generated in technological processes such as fermentation and extraction. This wastewater contains pollutants such as residual organic matter, nitrogen and phosphorus compounds, microbial metabolites, and suspended solids. If directly discharged, it will not only cause serious pollution to the soil and water bodies, but also lead to waste of resources. In response to the concept of energy conservation and environmental protection, biological fertilizer production enterprises need to effectively treat the wastewater to achieve the discharge of pollutants up to standard or resource recovery, reduce the environmental load during the production process, and at the same time improve the utilization rate of water resources.

[0003] Existing biological fertilizer production wastewater treatment devices usually adopt a three-stage treatment system: First, by intelligently adding chemicals such as flocculants, and cooperating with an automatic stirring device to mix the chemicals fully with the wastewater for reaction. After standing, preliminary precipitation or filtration is carried out to remove large particulate suspended solids. Subsequently, an activated carbon adsorption device is used to remove residual chromaticity, odor, and trace pollutants. Then, a water quality detection sensor can be used to detect whether the treated water quality meets the standard. If not, it is pumped for recycling. However, the traditional treatment system has significant defects: The processes of each treatment unit are relatively fragmented, and the scattered equipment leads to a large floor area and high energy consumption; in the activated carbon adsorption unit, granular activated carbon often cannot fully contact the wastewater due to close packing, and local pores are easily blocked by impurities, resulting in waste of adsorption sites and local saturation phenomena, thereby reducing the adsorption efficiency and affecting the overall treatment effect. Moreover, frequent replacement of the activated carbon filter element also increases the operation and maintenance costs.

[0004] Therefore, it is necessary to propose an intelligent conditioning and purification device for biological fertilizer production wastewater to solve the above problems. Summary of the Invention

The water blowing assembly includes a bottom shaft 17 movably penetrating through the middle of the top filter plate 13. The bottom shaft 17 is movably connected to the top filter plate 13. The lower end of the bottom shaft 17 extends below the bottom filter plate 14, and the bottom shaft 17 is rotatably connected to the bottom filter plate 14. Specifically, a bearing is penetrated through the middle of the bottom filter plate 14, and the bottom shaft 17 is fixedly connected to the inner wall of the bearing. A piston rod 29 corresponding to the bottom shaft 17 and in a hollow shape is rotatably arranged on the inner side of the lower end of the treatment tank body 1. The bottom shaft 17 is a hollow structure. The upper end of the piston rod 29 is movably connected to the inner side of the bottom shaft 17. A blowing port 26 located between the top filter plate 13 and the bottom filter plate 14 is communicated with the side wall of the bottom shaft 17. A one-way valve is arranged on the blowing port 26, and this one-way valve is configured to only allow water to be discharged from the blowing port 26 between the top filter plate 13 and the bottom filter plate 14. A suction port 25 is communicated with the side wall of the lower end of the piston rod 29. A one-way valve is arranged on the suction port 25, and this one-way valve is configured to only allow water to enter the inner sides of the piston rod 29 and the bottom shaft 17. An auxiliary ring 9 is arranged on the inner wall of the lower end of the treatment tank body 1. A first guide groove 10 in a fluctuating shape is arranged on the side surface of the auxiliary ring 9. The first guide groove 10 is arranged in a closed loop. A traction arm 24 corresponding to the auxiliary ring 9 is arranged on the side wall of the lower end of the bottom shaft 17. One end of the traction arm 24 extends into the inner side of the first guide groove 10. In order to reduce friction, a roller is arranged at the end of the traction arm 24 extending into the inner side of the first guide groove 10. The roller is in rolling fit with the inner wall of the first guide groove 10. Thus, when the roller moves in the first guide groove 10, it can drive the bottom shaft 17 to move up and down; Further, as Figure 2 、 Figures 4-7As shown in the figure, a rotary drive mechanism for driving the top shaft 18 and the bottom shaft 17 to rotate synchronously is provided at the upper end of the treatment tank body 1. As a preferred embodiment, the rotary drive mechanism includes a driven wheel 23 provided on the outer side of the upper end of the top shaft 18. One end of the top of the treatment tank body 1 is provided with a driving wheel 28 meshing with the driven wheel 23. One end of the top of the treatment tank body 1 is provided with a second drive source 15 for driving the driving wheel 28 to rotate. The second drive source 15 is preferably a reduction motor. The inner side of the top shaft 18 is vertically movably connected with a hollow first inner shaft 22. The first inner shaft 22 is polygonal prism-shaped to prevent relative rotation with the top shaft 18. The lower end of the first inner shaft 22 extends to the bottom of the pre-filter plate 12, and the first inner shaft 22 is rotatably connected with the pre-filter plate 12. Specifically, a bearing is fixedly penetrated through the middle of the pre-filter plate 12, and the lower end of the first inner shaft 22 is fixed to the inner wall of the bearing. The inner side of the lower end of the first inner shaft 22 is vertically movably connected with a second inner shaft 27 for driving the bottom shaft 17 to rotate therewith. The upper end of the second inner shaft 27 is provided with a polygonal prism-shaped anti-rotation shaft 32 to prevent relative rotation between the second inner shaft 27 and the first inner shaft 22. In order to avoid the up and down displacement of the bottom filter plate 14 during the stage of adding medicine and stirring, a one-way bearing is embedded at the bottom of the second inner shaft 27, and the upper end of the bottom shaft 17 is fixed to the inner wall of the one-way bearing. Thus, only the first inner shaft 22 rotates during stirring and adding medicine, and the bottom bottom shaft 17 does not rotate.

[0024] As Figures 5-9As shown in the figure, in order to prevent wastewater from falling from the pre-filter plate 12 during the stage of adding chemicals and stirring, a blocking component is provided at the bottom of the pre-filter plate 12. The blocking component includes a blocking plate 30 rotatably arranged at the bottom of the pre-filter plate 12. The blocking plate 30 is preferably fan-shaped and evenly arranged around the bottom of the pre-filter plate 12. The holes on the blocking plate 30 correspond to the holes on the pre-filter plate 12. A guide rod 42 corresponding to the blocking plate 30 and in an arc shape is fixed to the bottom of the pre-filter plate 12. One end of the guide rod 42 is movably connected to the inside of the convex ring 31. A second elastic member 39 is arranged at one end of the guide rod 42. The second elastic member 39 is preferably a spring, and the spring is sleeved outside the guide rod 42. When the second elastic member 39 is in the reset state, the holes on the blocking plate 30 correspond to the holes on the pre-filter plate 12. A linkage component for driving the displacement of the blocking plate 30 is arranged in the treatment tank body 1. The linkage component includes a force-receiving block 35 in an arc shape arranged on one side of the blocking plate 30. A fixing frame 36 corresponding to the blocking plate 30 is arranged at the bottom of the pre-filter plate 12. A push arm 34 is movably connected along the radial direction of the pre-filter plate 12 on the fixing frame 36. One end of the push arm 34 corresponds to the force-receiving block 35 and is used to push the force-receiving block 35. A thin shaft 33 with a diameter smaller than that of the second inner shaft 27 is arranged between the second inner shaft 27 and the anti-rotation shaft 32, and the connection between the thin shaft 33 and the second inner shaft 27 has a smooth transition. The end of the push arm 34 away from the force-receiving block 35 corresponds to the second inner shaft 27, and a ball is rotatably arranged at the end of the push arm 34 away from the force-receiving block 35, which can reduce the friction and the wear of the end of the push arm 34. A first driving source 7 for driving the lifting of the first inner shaft 22 is arranged at the upper end of the treatment tank body 1. The first driving source 7 is preferably a cylinder, or other driving devices capable of driving the lifting of the first inner shaft 22 can also be used as a substitute. The output shaft of the first driving source 7 is rotatably connected to the upper end of the first inner shaft 22, so as not to affect the rotation of the first inner shaft 22 following the top shaft 18. In order to facilitate the reset of the push arm 34, a flange 37 is arranged on the outer wall of one end of the push arm 34. A first elastic member 38 is arranged between the flange 37 and the fixing frame 36. The first elastic member 38 is preferably a spring, and the spring is sleeved outside the push arm 34.

[0025] Further, as Figures 1-3 、 Figures 11-12As shown in the figure, in order to process the sediment on the top of the pre-filter plate 12, a first slag discharge port 5 is evenly arranged around the upper side wall of the treatment tank body 1. A blocking cylinder 11 is rotatably arranged on the inner side of the upper side wall of the treatment tank body 1. A second slag discharge port 21 corresponding to the first slag discharge port 5 is arranged on the side wall of the blocking cylinder 11. A traction frame 6 is arranged on the top of the treatment tank body 1. A driving arm 20 extending to the inner side of the upper side wall of the treatment tank body 1 is arranged at the bottom of the traction frame 6. The driving arm 20 corresponds to the blocking cylinder 11. A spiral second guide groove 40 is arranged on the side wall of the blocking cylinder 11. A guide block 41 that is movably and guidingly matched with the second guide groove 40 is arranged on the side wall of the driving arm 20. The upper end of the guide post 16 penetrates through the traction frame 6 and is movably connected to the traction frame 6. A pair of convex rings 31 located on the upper and lower sides of the traction frame 6 are arranged at the upper end of the guide post 16. The convex rings 31 are used to push the traction frame 6 to move up and down. The second guide groove 40 and the guide block 41 are configured such that when the second slag discharge port 21 coincides with the first slag discharge port 5, the bottom of the stirring blade 19 just contacts the top of the pre-filter plate 12. A slag receiving groove 4 corresponding to the first slag discharge port 5 and in a ring shape is arranged on the outer wall of the upper end of the treatment tank body 1; It should be noted that a water quality detection sensor is also arranged at the bottom of the inner cavity of the treatment tank body 1 to detect whether the water quality meets the standard. If it does not meet the standard, it can be discharged and then subjected to a re-circulation treatment. The water quality detection sensor adopts a conventional sensor and will not be elaborated too much.

[0026] In the initial state, the push arm 34 abuts against the side wall of the second inner shaft 27. The holes on the blocking plate 30 and the holes on the pre-filter plate 12 are in a staggered state. The blocking plate 30 blocks the pre-filter plate 12, and the second slag discharge port 21 and the first slag discharge port 5 are also in a staggered state. The blocking cylinder 11 blocks the first slag discharge port 5; During use, the wastewater is introduced into the upper inner side of the treatment tank body 1 through the water inlet 2, and the chemical dosing device adds chemicals into the treatment tank body 1 through the chemical dosing port 3. The chemical dosing device adopts conventional technical means and will not be elaborated too much. Then, control the second driving source 15 to drive the driving wheel 28 to rotate. The driving wheel 28 drives the top shaft 18 to rotate through the driven wheel 23. The top shaft 18 drives the stirring blade plate 19 to stir and mix the chemicals and the wastewater. During this period, the first inner shaft 22 will also be driven by the top shaft 18 to rotate, and the second inner shaft 27 rotates following the first inner shaft 22. Since a one-way bearing is provided between the bottom shaft 17 and the second inner shaft 27, the bottom shaft 17 will not be driven to rotate during the stirring stage. After all the chemical dosing is completed and the reaction is sufficient, turn off the second driving source 15. Then, control the second driving source 15 to reverse and control the first driving source 7 to drive the first inner shaft 22 to rise. The first inner shaft 22 drives the pre-filter plate 12 and the guide post 16 to rise as a whole. The second inner shaft 27 and the first inner shaft 22 have a relative displacement. The push arm 34 follows and rises. The end of the push arm 34 displaces from the traction arm 24 to the thin shaft 33, and then extends along the side wall of the thin shaft 33 to rise. When corresponding to the thin shaft 33, the first elastic member 38 resets to drive the push arm 34 to reset. One section of the push arm 34 separates from the force-receiving block 35. Furthermore, the second elastic member 39 resets, and the blocking plate 30 rotates. The holes on the blocking plate 30 coincide with the holes on the pre-filter plate 12, and the wastewater falls. Since the stirring blade plate 19 is still rotating, the pre-filter plate 12 is not easily blocked. While the wastewater is falling, the pre-filter plate 12 is rising. During this period, since the first inner shaft 22 rotates reversely, the one-way bearing plays a role. The first inner shaft 22 drives the bottom shaft 17 to rotate synchronously through the second inner shaft 27. The traction arm 24 is driven to rotate following the bottom shaft 17. Under the action of the first guide groove 10, the traction arm 24 drives the bottom shaft 17 to rise and fall. Furthermore, the bottom shaft 17 drives the bottom filter plate 14 to rise and fall. When descending, the distance between the top filter plate 13 and the bottom filter plate 14 increases, and due to the action of the piston rod 29, the water sucked into the inner side of the bottom shaft 17 from the suction port 25 will be extruded from the blowing port 26. The extruded water is the treated water at the bottom and returns to the space between the top filter plate 13 and the bottom filter plate 14 to contact the activated carbon particles again to achieve secondary treatment. And since the gap between the top filter plate 13 and the bottom filter plate 14 increases, the blown water pressure can blow and disperse the activated carbon particles, enabling the activated carbon particles to fully contact the wastewater. When the bottom shaft 17 rises, the suction port 25 sucks water into the piston rod 29 and the inner side of the bottom shaft 17 again, and this cycle continues until the wastewater completely falls from the upper end of the pre-filter plate 12. Since the pre-filter plate 12 is in a continuously slow rising state, after rising for a period of time, the guide post 16 pushes the traction frame 6 to rise through the lower convex ring 31. The traction frame 6 drives the driving arm 20 to rise. Under the action of the guide block 41 and the second guide groove 40, the blocking cylinder 11 rotates. Furthermore, the second slag discharge port 21 coincides with the first slag discharge port 5. Finally, the pre-filter plate 12 will contact the stirring blade plate 19, and the first inner shaft 22 stops rising and continues to rotate. Since the stirring blade plate 19 is arc-shaped,Furthermore, the rotating stirring blade 19 can push the sediment on the top of the pre-filter plate 12 away from the top of the pre-filter plate 12 and discharge it from the first slag discharge port 5, and finally collect it by the slag receiving tank 4. A water quality sensor is also provided on the inner side of the bottom of the treatment tank body 1. If the water quality does not meet the standard, the water in the treatment tank body 1 can be discharged and then circulated continuously; The coaxial rotation of the device, the lifting of the pre-filter plate 12 and the bottom filter plate 14, and the sealing component linked with the lifting can not only realize step-by-step multi-stage water quality treatment, but also give full play to the role of activated carbon particles. Moreover, due to the rising of the pre-filter plate 12, the discharge and collection of sediment can be realized. The structure is compact and easy to use.

[0027] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
