Technical Field

[0001] The invention relates to an industrial wastewater zero-discharge water treatment system, belonging to the field of industrial wastewater zero-discharge. Background Art

[0002] With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies by wastewater has become increasingly widespread, posing a serious threat to human health and safety. For environmental protection, the treatment of industrial wastewater is more important than the treatment of urban sewage. With the gradual implementation of various national environmental protection policies and regulations, the intensity of environmental protection supervision has been continuously strengthened, and the restrictions on drainage volume and drainage water quality have become more and more stringent. In order to conscientiously implement relevant national policies and regulations, scientifically and reasonably recycle and utilize rainwater, domestic sewage, and industrial wastewater to achieve energy conservation and efficiency improvement, water conservation, emission reduction, improve the economic, environmental and social benefits of enterprises, completely eliminate environmental risks, and ultimately achieve zero sewage discharge.

[0003] At present, the Chinese invention with the announcement number CN114230041A discloses a zero-emission industrial wastewater treatment system. This invention discloses a zero-emission industrial wastewater treatment system in the field of cement pole pre-buried foundation structure technology, including a stirring and clarifying tank, the input end of the stirring and clarifying tank is connected to a reclaimed water pipeline, the output end of the stirring and clarifying tank is connected to the raw water tank through a raw water pump, and the other end is connected to the cooling tower through a circulating water make-up pump. It also includes a collection tank and an industrial wastewater tank. The input end of the collection tank is connected to a rainwater drainage pipeline through a rainwater drainage pump, and the output end of the industrial wastewater tank is connected to a coagulation and clarification tank and a filtration tank in sequence through a wastewater lifting pump.

After the system modification of this invention is completed, multiple uses of water, cascade use, and wastewater reuse are realized, avoiding the phenomenon of "high quality and low use" of water and the phenomenon that mixed collection cannot be recycled.

[0004] The existing industrial wastewater zero discharge water treatment system has the following disadvantages when in use:

[0005] When achieving zero-discharge treatment of industrial wastewater, coagulants, flocculants, conditioners and other agents that meet the requirements for neutralization and flocculation of industrial wastewater are usually mixed and added to the industrial wastewater, so that the industrial wastewater can produce flocculation and precipitation. In this process, the impurities after flocculation and precipitation cannot be separated from the water, thereby affecting the efficiency of zero-discharge treatment of industrial wastewater.

[0012] Furthermore, the feed ports on the upper and lower sides are staggered with each other, and guide rod holes are provided on both the nut moving block 1 and the nut moving block 2, and guide rods are provided in the guide rod holes. The two ends of the guide rods are connected and fixed to the inner walls on both sides of the working chamber, and the outer surface of the mixing tank is provided with a plurality of cleaning ports that cooperate with the annular member, and the cleaning port is located above the annular member, and a sealing plate 2 is provided in the cleaning port.

[0013] The transmission gear of the present invention is meshed with the gear of the driven gear and the gear of the driven gear is meshed with the gear of the driven gear.

[0015] Furthermore, the spreading mechanism also includes several groups of fixed frames fixed on the inner wall of the mixing chamber, the fixed frame and the movable chamber correspond to each other, and the fixed frame is slidably connected to the inside of the fixed frame with an inclined panel 2, the inclined end of the inclined panel 2 passes through the movable chamber and is squeezed together with the inclined surface of the vertical plate, and the inclined panel 2 is fixed with a rack at the top of a section inside the fixed frame, and several linkage gears are engaged with the top of the rack, and a rotating shaft is fixed to the middle of the linkage gear, and the end of the rotating shaft passes through the outside of the fixed frame, and a material guide plate is fixed between the two rotating shafts.

[0017] Furthermore, the material spreading mechanism also includes a storage cavity opened at the top center of the rotating column, the top of the rotating column carries the storage cavity through to the interior of the medicine tank, and a plurality of liquid outlet holes are opened on the inner wall of the storage cavity and penetrate to the outer surface of the rotating column, and the liquid outlet holes and the material guide plate are located on the same horizontal plane.

[0018] Beneficial effects of the present invention:

[0019] Through the design of the collection mechanism, the flocculated and precipitated impurities will enter the filter chamber along the feed port on the top of the annular member. After a period of sedimentation, the motor is started, and the motor drives the driving gear to rotate, and the driving gear drives the driven gears 1 and 2 on both sides to rotate, and the driven gears 1 and 2 respectively drive the threaded rods 1 and 2 to rotate, and the threaded rods 1 and 2 respectively drive the nut moving blocks 1 and nut moving blocks 2 to move horizontally and linearly, and the nut moving block 1 drives the inclined plate 1 to move while moving, and the inclined plate 1 will pass through the front section of the movement. The extrusion between the inclined surfaces pushes the inclined plate three and the blocking plate to move in a straight line. When the inclined surface of the inclined plate one passes the inclined surface of the inclined plate three, the inclined plate three has blocked the feed inlet under the push of the inclined plate one. Then, the second half of the inclined plate one moves and will no longer squeeze the inclined plate three, so that the inclined plate three is always in a blocked state. When the nut moving block two moves, it will push the pressure plate to move through the connecting piece. The movement of the pressure plate will squeeze the mixed liquid inside the filter chamber, and then the liquid in the mixed liquid will be discharged into the mixing chamber through the filter hole, and the flocculated precipitated impurities will be squeezed into blocks by the pressure plate.

[0020] Because the feed ports between two adjacent layers of annular parts are staggered with each other, when the pressure plate in the upper filter cavity squeezes the mixed liquid inside the filter cavity, the water flow discharged from the filter hole will impact between the two feed ports on the lower ring part, so that the flocculated and precipitated impurities accumulated between the two feed ports can flow to the feed ports on both sides, so that the flocculated and precipitated impurities can fully enter the feed port.

[0021] Through the design of the mixing mechanism, motor 2 drives the driving gear to rotate, and the driving gear drives the rotating plate to rotate through the outer gear ring, and the rotating plate drives the rotating column and the wave block to rotate. The rotating column rotates while driving several rotating rods to rotate synchronously. The rotation of the rotating rod drives the driven bevel gear to rotate horizontally. The driven bevel gear rotates horizontally while moving along the fixed bevel gear, thereby driving the driven bevel gear and the rotating rod to rotate longitudinally. The other end of the rotating rod drives several stirring blades to rotate. The stirring blades perform passive horizontal rotation and active longitudinal rotation, thereby completing the function of stirring and mixing the liquid in the mixing chamber.

[0022] Through the design of the spreading mechanism, the rotating rotating column will drive the flocculant in the storage chamber to rotate, and the flocculant will perform centrifugal motion and be thrown to various places inside the storage chamber along a number of liquid outlets. The rotating wave block is squeezed together with the bottom of the vertical plate, and the wave crest and trough structure of the wave block will be squeezed together with the bottom of the vertical plate back and forth, thereby pushing the vertical plate to perform vertical reciprocating movement. While the vertical plate is moving back and forth, it will squeeze the side slope of the inclined panel two through the inclined surface of the top, so that when the vertical plate rises, the inclined panel two can be pushed to the inside of the fixed frame through the inclined surface of the side of the inclined panel two. When the slanted plate moves, the rack on the top of the second inclined plate can synchronously push several linked gears to rotate, and the linked gears push the guide plate to rotate through the rotating shaft, so that the guide plate can make a reciprocating arc motion. The guide plate and the liquid outlet are located in the same horizontal plane. The flocculant thrown out from the liquid outlet can be squeezed together with several rotating guide plates, so that the thrown flocculant can be evenly dropped under the action of several guide plates, and the flocculant can be evenly settled inside the mixing chamber, so that the sewage inside the mixing chamber can be evenly combined with the flocculant and can be evenly stirred by the mixing mechanism.

The bottom end of the connecting piece 22 penetrates into the interior of the filter chamber 9 and is connected and fixed to the pressure plate 23. The collecting mechanism also includes an inlet and outlet opened between the feed port 8 and the working chamber 11. A blocking plate 51 is slidably connected in the inlet and outlet. The end of the blocking plate 51 penetrates into the interior of the working chamber 11 and is connected and fixed to the inclined plate 3 52. The inclined plate 3 52 is slidably connected to the working chamber 11. The inclined surface of the panel three 52 and the inclined surface of the inclined panel one 19 are squeezed together, and the feed ports 8 on the upper and lower sides are staggered with each other. Both the nut moving block one 18 and the nut moving block two 20 are provided with guide rod holes, and guide rods 21 are provided in the guide rod holes. The two ends of the guide rods 21 are connected and fixed to the inner walls of both sides of the working chamber 11. The outer surface of the mixing tank 3 is provided with a plurality of cleaning ports that cooperate with the annular member 7. The cleaning port is located above the annular member 7, and a sealing plate 2 is provided in the cleaning port.Through the design of the collecting mechanism, the flocculated and precipitated impurities will enter the filter chamber 9 along the feed port 8 at the top of the annular member 7. After a period of sedimentation, the motor 12 is started, and the motor 12 drives the driving gear 13 to rotate. The driving gear 13 drives the driven gear 16 and the driven gear 2 17 on both sides to rotate. The driven gear 16 and the driven gear 2 17 respectively drive the threaded rod 14 and the threaded rod 2 15 to rotate. The threaded rod 14 and the threaded rod 2 15 respectively drive the nut moving block 18 and the nut moving block 2 20 to move horizontally and linearly. The nut moving block 18 drives the inclined plate 19 to move while moving. The inclined plate 19 is at the front end of the movement. The compression between the inclined surfaces pushes inclined plate 3 52 and blocking plate 1 51 to move linearly. When the inclined surface of inclined plate 19 passes the inclined surface of inclined plate 3 52, inclined plate 3 52, pushed by inclined plate 19, has already blocked feed port 8. Then, the second half of inclined plate 19 moves, no longer squeezing inclined plate 3 52, ensuring that inclined plate 3 52 remains in the blocked state. As nut moving block 20 moves, it pushes pressure plate 23 via connector 22. This movement squeezes the mixed liquid inside filter chamber 9, causing the liquid in the mixed liquid to be discharged into mixing chamber 6 through filter holes 10, while flocculated and precipitated impurities are squeezed into blocks by pressure plate 23.

[0044] See Figure 2-4 、 Figure 8-10The mixing mechanism includes an active chamber 24 opened below the mixing chamber 6, a motor 25 is fixed on one side of the bottom of the active chamber 24, and a driving gear 26 is connected to the top output end of the motor 25, and a rotating plate 27 is rotatably connected in the middle of the active chamber 24, and an outer gear ring 29 is provided at the bottom center of the rotating plate 27, and the outer gear ring 29 is meshed with the driving gear 26, and a rotating column 30 is fixed at the top center of the rotating plate 27, and a linkage chamber 32 is opened in the inner top of the rotating column 30, and a fixed rod 31 is provided in the middle of the linkage chamber 32, and a plurality of fixed bevel gears 33 are fixed at equal intervals on the top outer surface of the fixed rod 31, and a plurality of rotating rods 34 are movably connected on the side wall of the linkage chamber 32, and a driven bevel gear 35 is fixed at one end of the rotating rod 34, and the driven bevel gear 35 is meshed with the fixed bevel gear 33, and the other end of the rotating rod 34 passes through the rotating The outer side of the column 30 is connected and fixed with several stirring blades 36, and the bottom end of the fixed rod 31 passes through the rotating column 30 and the rotating plate 27, extends to the bottom of the active chamber 24 and is connected and fixed with the inner wall of the active chamber 24; through the design of the mixing mechanism, the motor 25 drives the driving gear 26 to rotate, and the driving gear 26 drives the rotating plate 27 to rotate through the outer gear ring 29, and the rotating plate 27 drives the rotating column 30 and the wave block 28 to rotate. While the rotating column 30 rotates, it drives several rotating rods 34 to rotate synchronously, and the rotating rod 34 rotates to drive the driven bevel gear 35 to rotate horizontally. While the driven bevel gear 35 rotates horizontally, it moves along the fixed bevel gear 33, thereby driving the driven bevel gear 35 and the rotating rod 34 to rotate longitudinally. The other end of the rotating rod 34 drives several stirring blades 36 to rotate, and the stirring blades 36 perform passive horizontal rotation and active longitudinal rotation, thereby completing the effect of stirring and mixing the liquid in the mixing chamber 6.

[0045] See Figure 11-16, the material spreading mechanism includes several wave blocks 28 fixed to the circumferential side of the top of the rotating plate 27 and several groups of mobile chambers 40 opened at the top of the active chamber 24, the interior of the mobile chamber 40 is slidably connected with a vertical plate 41, the bottom of the vertical plate 41 is squeezed together with the wave block 28, and the top of the vertical plate 41 is provided with an inclined surface, and the material spreading mechanism also includes several groups of fixed frames 42 fixed on the inner wall of the mixing chamber 6, the fixed frame 42 and the mobile chamber 40 correspond to each other, and an inclined panel 2 43 is slidably connected to the interior of the fixed frame 42, the inclined surface end of the inclined panel 2 43 passes through the mobile chamber 40 and is squeezed together with the inclined surface of the vertical plate 41, and the inclined panel 2 43 is at the top of a section inside the fixed frame 42 A rack 44 is fixed to the top of the rack 44, and a number of linkage gears 46 are engaged with the top of the linkage gear 46. A rotating shaft 45 is fixed to the middle of the linkage gear 46. The end of the rotating shaft 45 passes through the outside of the fixed frame 42, and a guide plate 47 is fixed between the two rotating shafts 45. A slider is fixed to the bottom of the inclined plate 43, and a slide groove that cooperates with the slider is provided at the bottom of the fixed frame 42. A return spring is provided inside the slide groove, and the slider and the return spring are squeezed together. The spreading mechanism also includes a storage chamber 37 opened at the top center of the rotating column 30. The top of the rotating column 30 passes through the storage chamber 37 to the inside of the medicine tank 4, and a number of penetrations are provided on the inner wall of the storage chamber 37. To the liquid outlet 38 on the outer surface of the rotating column 30, the liquid outlet 38 and the guide plate 47 are located at the same horizontal plane; through the design of the spreading mechanism, the rotating rotating column 30 will drive the flocculant in the storage chamber 37 to rotate, and the flocculant will perform centrifugal motion, and at the same time be thrown to various places inside the storage chamber 37 along a number of liquid outlets 38, and the rotating wave block 28 will be squeezed together with the bottom of the vertical plate 41, and the wave crest and trough structure of the wave block 28 will be reciprocated and squeezed together with the bottom of the vertical plate 41, thereby pushing the vertical plate 41 to perform a vertical reciprocating movement. While the vertical plate 41 reciprocates vertically, it will squeeze the side inclined surface of the inclined panel 2 43 through the inclined surface of the top, so that the inclined panel 2 43 can pass through the inclined panel 2 when the vertical plate 41 rises. The inclined surface on the side of 43 pushes the inclined panel 2 43 to move toward the inside of the fixed frame 42. During the movement, the rack 44 on the top of the inclined panel 2 43 can synchronously push several linked gears 46 to rotate. The linked gear 46 pushes the guide plate 47 to rotate through the rotating shaft 45, so that the guide plate 47 can make a reciprocating arc motion. The guide plate 47 and the liquid outlet 38 are located in the same horizontal plane. The flocculant thrown out from the liquid outlet 38 can be squeezed together with several rotating guide plates 47, so that the thrown flocculant can be evenly dropped under the action of several guide plates 47, so that the flocculant can be evenly settled inside the mixing chamber 6, so that the sewage inside the mixing chamber 6 can be evenly combined with the flocculant and can be evenly stirred by the mixing mechanism.

[0046] When in use, the sewage in the sewage tank 2 is transported to the mixing tank 3 through the delivery pump and the feed pipe 50. When the high liquid level sensor detects that the sewage level reaches the set height, the sewage tank 2 stops transporting sewage to the mixing tank 3.

[0047] Next, the second motor 25 drives the driving gear 26 to rotate, and the driving gear 26 drives the rotating plate 27 to rotate through the outer gear ring 29. The rotating plate 27 drives the rotating column 30 and the wave block 28 to rotate. The rotating column 30 rotates and drives the plurality of rotating rods 34 to rotate synchronously. The rotation of the rotating rod 34 drives the driven bevel gear 35 to rotate horizontally. The driven bevel gear 35 rotates horizontally and moves along the fixed bevel gear 33, thereby driving the driven bevel gear 35 and the rotating rod 34 to rotate longitudinally. The other end of the rotating rod 34 drives the plurality of stirring blades 36 to rotate. The stirring blades 36 perform passive horizontal rotation and active longitudinal rotation, thereby completing the function of stirring and mixing the liquid in the mixing chamber 6.

[0048] At the same time, the rotating rotating column 30 will drive the flocculant in the storage chamber 37 to rotate, and the flocculant will perform centrifugal motion and be thrown to various places inside the storage chamber 37 along the several liquid outlet holes 38. The rotating wave block 28 is squeezed together with the bottom of the vertical plate 41, and the wave crest and trough structure of the wave block 28 is reciprocated and squeezed together with the bottom of the vertical plate 41, thereby pushing the vertical plate 41 to perform vertical reciprocating movement. While the vertical plate 41 is reciprocating, it will squeeze the side inclined surface of the inclined panel 2 43 through the inclined surface of the top, so that when the vertical plate 41 rises, the inclined panel 2 43 can be pushed into the fixed frame 42 through the inclined surface of the side of the inclined panel 2 43. The second inclined plate 43 moves, and at the same time, the rack 44 on the top of the inclined plate 43 can synchronously drive the plurality of linked gears 46 to rotate, and the linked gear 46 drives the guide plate 47 to rotate through the rotating shaft 45, so that the guide plate 47 can make a reciprocating arc motion, and the guide plate 47 and the liquid outlet 38 are located at the same horizontal plane, and the flocculant thrown out from the liquid outlet 38 can be squeezed together with the plurality of rotating guide plates 47, so that the thrown flocculant can be uniformly dropped under the action of the plurality of guide plates 47, so that the flocculant can be uniformly settled inside the mixing chamber 6, so that the sewage inside the mixing chamber 6 can be uniformly combined with the flocculant and can be uniformly stirred by the mixing mechanism;

[0049] After the flocculant combines with the sewage for a period of time, the industrial wastewater will form flocculated precipitated impurities and water. Because the bottom of the mixing chamber 6 is a conical structure, and several annular members 7 are also arranged at equal intervals from large to small along the conical structure, the settled flocculated precipitated impurities will settle on the top of the annular member 7. The flocculated precipitated impurities located in the middle of the mixing chamber 6 will also flow to the side of the mixing chamber 6 due to the centrifugal force formed by the stirring liquid, and then the flocculated precipitated impurities will enter the filter chamber 9 along the feed port 8 at the top of the annular member 7. After sedimentation for a period of time, the motor 12 is started, and the motor 12 drives the driving gear 13 to rotate. The driving gear 13 drives the driven gear 16 and the driven gear 2 17 on both sides to rotate. The driven gear 1 6 and the driven gear 2 17 respectively drive the threaded rod 14 and the threaded rod 2 15 to rotate, and the threaded rod 14 and the threaded rod 2 15 respectively drive the nut moving block 18 and the nut moving block 2 20 to move horizontally and linearly. The nut moving block 18 drives the inclined plate 19 to move while moving. The inclined plate 19 will push the inclined plate 3 52 and the blocking plate 1 51 to move linearly through the extrusion between the inclined surfaces in the front section of the movement. When the inclined surface of the inclined plate 19 passes the inclined surface of the inclined plate 3 52, the inclined plate 3 52 has blocked the feed port 8 under the push of the inclined plate 19. Then, the second half of the inclined plate 19 moves and will no longer squeeze the inclined plate 3 52, so that the inclined plate 3 52 is always in a blocked state.

[0050] When the nut moving block 20 moves, it pushes the pressure plate 23 to move through the connecting piece 22. The movement of the pressure plate 23 squeezes the mixed liquid inside the filter chamber 9, so that the liquid in the mixed liquid is discharged into the mixing chamber 6 through the filter hole 10, and the flocculated impurities are squeezed into blocks by the pressure plate 23. After a period of use, the staff can open several cleaning ports to clean and remove the flocculated impurities inside the filter chamber 9.

[0051] Because the feed ports 8 between two adjacent layers of annular members 7 are staggered with each other, when the pressure plate 23 in the upper filter chamber 9 squeezes the mixed liquid inside the filter chamber 9, the water flow discharged from the filter hole 10 will impact between the two feed ports 8 on the lower annular member 7, so that the flocculated and precipitated impurities accumulated between the two feed ports 8 can flow to the feed ports 8 on both sides, so that the flocculated and precipitated impurities can fully enter the feed port 8.

[0052] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
