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 wastewater produced by biological fertilizer production. Background Art

[0002] During biofertilizer production, fermentation, extraction, and other process steps generate large amounts of high-concentration organic wastewater. This wastewater contains pollutants such as residual organic matter, nitrogen and phosphorus compounds, microbial metabolites, and suspended solids. Direct discharge of this wastewater not only severely pollutes soil and water, but also leads to a waste of resources. To address energy conservation and environmental protection, biofertilizer manufacturers must effectively treat wastewater to ensure pollutant discharge meets standards or is recycled for resource reuse, reducing the environmental impact of the production process while improving water resource utilization.

[0003] Existing bio-fertilizer production wastewater treatment equipment usually adopts a three-stage treatment system: first, through the intelligent addition of flocculants and other agents, the mixed agents are fully reacted with the wastewater with the automatic stirring device, and then preliminary precipitation or filtration is carried out after standing to remove large particles of suspended solids. Subsequently, the activated carbon adsorption device is used to remove residual color, odor and trace pollutants. After that, the water quality detection sensor can be used to detect whether the treated water quality meets the standard. If it does not meet the standard, it will continue to be pumped and circulated. However, the traditional treatment system has significant defects: the processes of each treatment unit are relatively fragmented, and the equipment is scattered, resulting in a large footprint and high energy consumption. In the activated carbon adsorption unit, the granular activated carbon is often unable to fully contact with the wastewater due to its dense stacking, and the local pores are easily blocked by impurities, resulting in wasted adsorption sites and local saturation, thereby reducing the adsorption efficiency and affecting the overall treatment effect. Frequent replacement of activated carbon filter elements also increases operation and maintenance costs.

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

[0044] Further, such as Figure 2 、 Figure 4-Figure 7As shown, the upper end of the processing tank body 1 is provided with a rotary drive mechanism for driving the top shaft 18 and the bottom shaft 17 to rotate synchronously.

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 provided in the processing tank body 1. The linkage component includes an arc-shaped force block 35 provided on one side of the blocking plate 30.

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 resetting of the push arm 34, a flange 37 is provided on the outer wall of one end of the push arm 34, and a first elastic member 38 is provided between the flange 37 and the fixing frame 36. The first elastic member 38 is preferably a spring, and the spring is sleeved on the outside of the push arm 34.

[0046] Further, such as Figure 1-Figure 3 、 Figure 11-12As shown, 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 processing tank body 1, a sealing cylinder 11 is rotatably arranged on the inner side of the upper side wall of the processing tank body 1, and a second slag discharge port 21 corresponding to the first slag discharge port 5 is provided on the side wall of the sealing cylinder 11. A traction frame 6 is provided on the top of the processing tank body 1, and a driving arm 20 extending to the inner side of the upper side wall of the processing tank body 1 is provided at the bottom of the traction frame 6.

The side wall of the driving arm 20 is provided with a guide block 41 that is movably guided by the second guide groove 40. The upper end of the guide column 16 passes through the traction frame 6 and is movably connected to the traction frame 6. The upper end of the guide column 16 is provided with a pair of convex rings 31 located on the upper and lower sides of the traction frame 6. The convex rings 31 are used to push the traction frame 6 up and down. The second guide groove 40 and the guide block 41 are configured so 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. The upper outer wall of the processing tank body 1 is provided with an annular slag receiving groove 4 corresponding to the first slag discharge port 5;

[0047] It should be noted that a water quality detection sensor is also provided at the bottom of the inner cavity of the treatment tank body 1 to detect whether the water quality meets the standards. If it does not meet the standards, it can be eliminated and recycled again. The water quality detection sensor uses a conventional sensor and will not be elaborated on.

[0048] 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 staggered, 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 staggered, and the blocking cylinder 11 blocks the first slag discharge port 5;

[0049] During use, wastewater is introduced into the inner upper end of the treatment tank body 1 through the water inlet 2, and the chemical dosing device adds chemicals to the inside of the treatment tank body 1 through the chemical dosing port 3. The chemical dosing device adopts conventional technical means and will not be described in detail. Then the second driving source 15 is controlled to drive the driving wheel 28 to rotate, and the driving wheel 28 drives the top shaft 18 to rotate through the driven wheel 23. The top shaft 18 drives the stirring blade 19 to stir and mix the chemical and wastewater. During this period, the first inner shaft 22 will also be driven to rotate by the top shaft 18, and the second inner shaft 27 follows the first inner shaft 22 to rotate. 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 chemical additions are completed and the reaction is sufficient, the second driving source 15 is turned off. , 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 column 16 to rise as a whole, the second inner shaft 27 and the first inner shaft 22 are relatively displaced, the push arm 34 follows and rises, the end of the push arm 34 is displaced from the traction arm 24 to the thin shaft 33, and then the side wall of the thin shaft 33 is extended to rise, and when it corresponds to the thin shaft 33, the first elastic member 38 is reset to drive the push arm 34 to reset, and a section of the push arm 34 is separated from the force block 35, and then the second elastic member 39 is reset, the blocking plate 30 rotates, and 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 19 is still rotating, the pre-filter plate 12 is not easily blocked, and the wastewater As the water falls, the pre-filter plate 12 rises. During this period, due to the reversal of the first inner shaft 22, the one-way bearing comes into play, and 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 with 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, and then 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 from the suction port 25 on the inside of the bottom shaft 17 will be squeezed out from the blowing port 26. The squeezed water is the treated water at the bottom end, and returns to the space between the top filter plate 13 and the bottom filter plate 14 to contact with the activated carbon particles, thereby achieving secondary treatment. In addition, due to the space between the top filter plate 13 and the bottom filter plate 14 The gap increases, and the blown water pressure can blow and disperse the activated carbon particles, so that the activated carbon particles can fully contact with the wastewater. When the bottom shaft 17 rises, the suction port 25 again sucks in the water piston rod 29 and the inner side of the bottom shaft 17, 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 state of continuous and slow rising, after rising for a period of time, the guide column 16 pushes the traction frame 6 to rise through the convex ring 31 below, and 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 sealing cylinder 11 rotates, and then 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 19, and the first inner shaft 22 stops rising and continues to rotate. Since the stirring blade 19 is arc-shaped,Then, 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 be collected by the slag receiving trough 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 continue to circulate;

[0050] The device coaxially rotates with the lifting of the pre-filter plate 12 and the bottom filter plate 14, and cooperates with the blocking component that is linked to the lifting, which can not only realize step-by-step multi-stage water quality treatment, but also give full play to the role of activated carbon particles.
