Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, in particular to a wastewater treatment and recovery device for zirconium dioxide production. Background Art

[0002] Zirconium dioxide is the main oxide of zirconium. Under normal circumstances, it is white, odorless and tasteless crystals. It is difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. It is chemically inactive and has the properties of high melting point, high resistivity, high refractive index and low thermal expansion coefficient, making it an important high-temperature resistant material, ceramic insulating material and ceramic sunscreen. It is also the main raw material for artificial diamonds.

[0003] In the process of zirconium dioxide preparation, production wastewater is inevitably generated. In order to meet the emission standards, the wastewater needs to be treated. Common treatment steps include flocculation. Since the wastewater generated in the preparation process usually contains zirconium (such as zircon cleaning, acid washing and other steps), the zirconium in the wastewater can be separated after flocculation treatment, thereby achieving wastewater treatment and waste recycling at the same time.

[0004] The staff found that during the flocculation reaction, flocculants (such as polyaluminum chloride, polyacrylamide, etc.) react with suspended matter and colloidal substances in the water to form larger flocs. These flocs will settle or float in the pool, affecting the subsequent solid-liquid separation process. If not cleaned in time, the flocs will accumulate excessively, causing the space in the pool to be occupied and the settling rate of the flocs to slow down, thereby affecting the fluidity and flocculation efficiency of the water flow.

[0005] To this end, the present invention provides a wastewater treatment and recovery device for zirconium dioxide production. Summary of the invention

During this process, the sliding frame moves synchronously, driving the transmission shaft to rotate, thereby realizing the rotation of the guide spiral plate through the rotation of the mounting frame to facilitate the discharge of flocculants, and at the same time prolonging the time that the storage cylinder is located obliquely above the liquid inlet bucket, so that the flocculants and sewage in the storage cylinder can be fully discharged.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 10 As shown, a wastewater treatment and recovery device for zirconium dioxide production described in the present invention includes a flocculation part, a filtering mechanism, a material guiding mechanism, a drainage mechanism and a control mechanism.

[0023] The flocculation part includes a flocculation tank 1, an aeration pipe 13 and a guide pipe 21, wherein a stirring barrel 8 and a control pump 11 are arranged on one side of the flocculation tank 1, the output end of the control pump 11 is connected to the bottom surface of the stirring barrel 8, and a stirring shaft driven by a motor is arranged in the stirring barrel 8. When treating the wastewater generated in the zirconium dioxide production process, the flocculant and the wastewater are injected into the stirring barrel 8 at the same time. At this time, the flocculant and the wastewater are stirred and controlled by the stirring shaft in the stirring barrel 8. After mixing, the mixture is injected into the flocculation tank 1 through the control pump 11, thereby flocculating the wastewater in production to separate the zirconium ions in ionic state so as to recover useful substances in sewage treatment.

[0024] One end of the aeration pipe 13 is connected to an external aeration pump, and the other end extends to the interior of the flocculation tank 1. The guide pipe 21 is obliquely arranged on the outer wall of the aeration pipe 13 and is connected to the inner cavity of the aeration pipe 13. During the sewage flocculation process, in order to improve the flocculation efficiency, oxygen needs to be introduced into the flocculation tank 1. At this time, the external aeration pump exhausts the wastewater in the flocculation tank 1 through the aeration pipe 13 and the guide pipe 21. At this time, aeration can not only provide oxygen but also control the water flow toward the exhaust direction through the inclined setting of the guide pipe 21.

[0025] The filtering mechanism includes a supporting frame 14, a supporting cylinder 9 and a filter cylinder 15. The supporting cylinder 9 is installed at the upper end of the flocculation tank 1 through the supporting frame 14, and the filter cylinder 15 is arranged at the bottom of the supporting cylinder 9. The supporting cylinder 9 and the filter cylinder 15 are both arc-shaped structures, and a complete cylindrical structure is formed by the supporting cylinder 9 and the filter cylinder 15.

[0026] The upper end of the support cylinder 9 is provided with an opening, and the stirred sewage discharged by the control pump 11 enters the support cylinder 9 through the upper end opening of the support cylinder 9, and then the sewage flows to the filter cylinder 15 by gravity. In the process of stirring the sewage and the flocculant, floccules are gradually generated in the stirring barrel 8, and the floccules are passed through the filter cylinder 15 and the sewage that is not fully flocculated is discharged into the interior of the flocculation tank 1. In the flocculation process, the flocculent content in the flocculation tank 1 is reduced to maintain the flocculation efficiency.

[0027] The material guiding mechanism includes a transmission shaft 19 and a material guiding spiral plate 18. The transmission shaft 19 is rotatably arranged in the support tube 9. The material guiding spiral plate 18 is fixedly installed on the radial outer wall of the transmission shaft 19. Rotating the transmission shaft 19 drives the material guiding spiral plate 18 to rotate synchronously.

[0028] The outer walls of the guide spiral plate 18 are respectively fitted with the inner walls of the support tube 9 and the filter tube 15. When the guide spiral plate 18 rotates, it scrapes the outer wall of the filter tube 15 to scrape off the filtered flocculants and discharge them toward one axial end of the guide spiral plate 18 to facilitate the recovery of residues.

[0029] The drainage mechanism includes a mounting frame 4, a transmission plate 5 and a storage cylinder 3. The mounting frame 4 is rotatably disposed on the flocculation tank 1, and the bottom is located in the flocculation tank 1. After sewage is injected into the flocculation tank 1, the bottom of the mounting frame 4 is located below the sewage liquid level.

[0030] The transmission plate 5 and the storage cylinder 3 are both arranged on the inner wall of the installation frame 4. When the guide pipe 21 is exhausted, the sewage water flows and impacts the transmission plate 5, thereby pushing the installation frame 4 to rotate. At this time, the installation frame 4 rotates along its own axis. When the storage cylinder 3 is located below the sewage liquid level, the sewage and flocculants enter the interior of the storage cylinder 3. As the installation frame 4 rotates, the storage cylinder 3 storing the sewage is driven to move.

[0031] The storage cylinder 3 is tilted, and as the mounting frame 4 rotates, the storage cylinder 3 gradually moves away from the sewage surface. At this time, the storage cylinder 3 is tilted, so that the open end of the storage cylinder 3 can be tilted upward, reducing the loss of sewage in the storage cylinder 3. When the storage cylinder 3 passes the highest position of the mounting frame 4, its open end faces downward to facilitate the discharge of sewage and flocculants in the storage cylinder 3 (when the sewage is discharged, its trajectory is a parabola). At this time, the storage cylinder 3 pours the sewage and flocculants into the opening at the upper end of the support cylinder 9, thereby filtering the flocculants in the sewage inside the flocculation tank 1. In this process, filtration and flocculation are carried out synchronously. At the same time, the flocculant content in the flocculation tank 1 is reduced, which helps to maintain the flocculation efficiency and thus improve the sewage treatment efficiency.

[0032] It should be noted that the cylindrical structure composed of the support cylinder 9 and the filter cylinder 15 has no intersection with the rotation trajectory of the storage cylinder 3, so as to prevent the support cylinder 9 and the filter cylinder 15 from hindering the movement of the storage cylinder 3 when the storage cylinder 3 rotates with the installation frame 4.

[0033] In this embodiment, the flow of water in the flocculation tank 1 during aeration is utilized to control the rotation of the mounting frame 4, thereby transferring the sewage from the flocculation tank 1 to the filter cartridge 15, thereby reducing the content of flocculants in the flocculation tank 1, and promoting each other to jointly improve the efficiency of flocculation treatment of sewage.

[0034] The control mechanism is used to control the rotation of the transmission shaft 19, which serves as a driving force for controlling the rotation of the material guiding spiral plate 18, thereby facilitating the recovery of useful substances in the sewage.

[0035] A fixing plate 10 is fixedly installed on the outer wall of the support cylinder 9, and the outer wall of the filter cylinder 15 is fixedly connected to the outer wall of the fixing plate 10. The filter cylinder 15 and the support cylinder 9 are connected through the fixing plate 10, thereby realizing the connection between the support cylinder 9 and the filter cylinder 15 to form a complete cylindrical structure.

[0036] A conical cylinder 12 is fixedly installed at one axial end of the support cylinder 9, and the outer wall of the guide spiral plate 18 is slidably fitted with the inner wall of the conical cylinder 12. The conical cylinder 12 gradually shrinks at one end of the support cylinder 9, and is used to prevent sewage from flowing out by gradually increasing the height of the inner wall of the conical cylinder 12 when sewage enters the support cylinder 9 and the filter cylinder 15. When the guide spiral plate 18 rotates, the axial thrust provided pushes the object flocculants to be discharged from the shrinking end of the conical cylinder 12.

[0037] It should be noted that when the guide spiral plate 18 rotates, in order to prevent the axial thrust generated by it from causing the liquid to be discharged from the conical tube 12, the rotation speed of the transmission shaft 19 needs to be controlled to prevent sewage from overflowing.

[0038] A liquid inlet hopper 6 is fixedly installed on the upper end surface of the support cylinder 9, and the mixture inside the storage cylinder 3 enters the inner cavity of the support cylinder 9 through the liquid inlet hopper 6. By setting the liquid inlet hopper 6, the area for receiving sewage can be increased when the storage cylinder 3 is dumped with sewage, so as to facilitate the entry of sewage.

[0039] The upper end surface of the flocculation tank 1 is fixedly mounted with a bearing shaft 2, and the mounting frame 4 is rotatably mounted on the outer wall of the bearing shaft 2. The mounting frame 4 is connected to the bearing shaft 2 via a bearing, which provides support for the mounting frame 4 while reducing the resistance to rotation of the mounting frame 4.

[0040] As a preferred embodiment of the present invention, a mounting cylinder 7 is fixedly mounted on the upper end surface of the carrier frame 14, one end of the transmission shaft 19 extends to the inner cavity of the mounting cylinder 7, and a spiral groove 26 is provided. The transmission shaft 19 is rotated in the mounting cylinder 7 to drive the material guide spiral plate 18 to rotate, so as to control the discharge of the filtered flocculants.

[0041] A sliding frame 28 is slidably installed in the inner cavity of the mounting tube 7, and a control ring 27 is rotatably installed on the inner wall of the sliding frame 28. The inner wall of the control ring 27 slides and fits with the radial outer wall of the transmission shaft 19, wherein the axes of the transmission shaft 19, the control ring 27 and the sliding frame 28 are all coincident. The sliding frame 28 is slidably adjusted along the inner wall of the mounting tube 7 to drive the control ring 27 to slide synchronously along the outer wall of the transmission shaft 19.

[0042] The inner wall of the control ring 27 is fixedly mounted with a protrusion that slides with the spiral groove 26. The protrusion is hemispherical, and its outer wall slides and fits with the inner wall of the spiral groove 26. When the control ring 27 is slid along the axial direction of the control ring 27, the transmission shaft 19 is driven to rotate through the cooperation of the protrusion and the spiral groove 26, which is used to control the rotation of the material guide spiral plate 18 and rotate the control ring 27 along the outer wall of the transmission shaft 19. At this time, the control ring 27 is driven to move along the axial direction of the transmission shaft 19 through the cooperation of the protrusion and the spiral groove 26.

[0043] A guide bevel block 31 is fixedly mounted on the outer wall of the control ring 27, and a guide bevel plate 32 for pressing the guide bevel block 31 is elastically mounted on the inner wall of the sliding frame 28. The guide bevel plate 32 is made of elastic material, and the one-way transmission of the sliding frame 28 and the control ring 27 is realized through the cooperation of the guide bevel block 31 and the guide bevel plate 32, that is, when the control ring 27 rotates forward, the guide bevel block 31 and the guide bevel plate 32 slip, and when the control ring 27 rotates reversely, the guide bevel plate 32 and the guide bevel block 31 are stuck.

[0044] When the sliding frame 28 slides, the guide bevel block 31 is locked by the guide bevel plate 32, thereby driving the control ring 27 to slide. At this time, the control ring 27 cannot rotate, and then the transmission shaft 19 is controlled to rotate through the cooperation of the protrusion and the spiral groove 26.

[0045] When the sliding frame 28 slides in the reverse direction, the guide bevel block 31 and the guide bevel plate 32 slip, causing the control ring 27 to rotate under the condition that the protrusion and the spiral groove 26 cooperate, and the transmission shaft 19 remains stationary.

[0046] At this time, the transmission shaft 19 is controlled to rotate intermittently in the same direction by reciprocating sliding adjustment sliding frame 28, wherein the intermittent rotation of the transmission shaft 19 has the advantage of providing reaction time for the sewage to leak downward, thereby preventing the axial thrust from driving the sewage out when the guide spiral plate 18 rotates continuously.

[0047] As a preferred embodiment of the present invention, a pneumatic cylinder 25 is fixedly installed on the inner wall of the mounting cylinder 7, and a piston ring 30 is slidably installed on the inner wall of the pneumatic cylinder 25. The radial outer wall of the piston ring 30 is sealed with the inner wall of the pneumatic cylinder 25, and the sliding of the piston ring 30 is controlled by adjusting the air pressure in the inner cavity of the pneumatic cylinder 25.

[0048] One end of the piston ring 30 is connected to the outer wall of the sliding frame 28 via a connecting rod. When the piston ring 30 slides, the sliding frame 28 is driven to slide synchronously.

[0049] The control mechanism includes a control cylinder 20 and a control plug 24. The control cylinder 20 is fixedly mounted on the radial outer wall of the load-bearing shaft 2, and the control plug 24 is elastically mounted in the inner cavity of the control cylinder 20. The control plug 24 is connected to the inner wall of the control cylinder 20 through a spring. The radial outer wall of the control plug 24 is sealed and fitted with the inner wall of the control cylinder 20. The control plug 24 is pressed to adjust the air pressure in the inner cavity of the control cylinder 20, and then the control plug 24 is pushed to reset by the elastic force of the spring.

[0050] The inner cavity of the control cylinder 20 is connected with the inner cavity of the air pressure cylinder 25 through a conduit, and the air pressure in the inner cavities of the control cylinder 20 and the air pressure cylinder 25 are synchronously adjusted by the sliding control plug 24. At this time, the piston ring 30 drives the sliding frame 28 to slide.

[0051] An active arc block 23 is fixedly mounted on the side wall of the mounting frame 4 . A plurality of active arc blocks 23 are evenly arranged in a ring shape along the axis of the bearing shaft 2 . The outer wall of the active arc block 23 is inclined.

[0052] A driven arc block 22 is fixedly installed at one axial end of the control plug 24. The outer wall of the driven arc block 22 is slidably fitted with the outer wall of the active arc block 23. When the mounting frame 4 rotates, the driven arc block 22 is pushed by the active arc block 23 and the control plug 24 is driven to slide, compressing the air pressure in the inner cavity of the control cylinder 20. As the active arc block 23 and the driven arc block 22 slide alternately until the apex of the active arc block 23 passes over the apex of the driven arc block 22, the spring pushes the control plug 24 to slide, and the driven arc block 22 pushes the active arc block 23 to slide until the control plug 24 is reset, which is used to drive the reciprocating adjustment of the air pressure in the inner cavity of the control cylinder 20. When the air pressure in the inner cavity of the control cylinder 20 is reciprocated, the air pressure in the air pressure cylinder 25 is reciprocated, and the piston ring 30 slides reciprocatingly synchronously. In this process, the sliding frame 28 moves synchronously to drive the transmission shaft 19 to rotate, thereby realizing the rotation of the guide spiral plate 18 through the rotation of the mounting frame 4 to facilitate the discharge of flocculants.

[0053] There are multiple storage cylinders 3, and the number is consistent with the active arc block 23. When the active arc block 23 presses the driven arc block 22, the open end of the storage cylinder 3 is located obliquely above the liquid inlet bucket 6. When the active arc block 23 pushes the driven arc block 22, the elastic force of the spring hinders the sliding of the control plug 24, thereby increasing the resistance to the rotation of the mounting frame 4 at this time, which is used to reduce the rotation speed of the mounting frame 4 at this time, and to prolong the time that the storage cylinder 3 is located obliquely above the liquid inlet bucket 6, so that the flocculants and sewage in the storage cylinder 3 can be fully discharged.

[0054] As a preferred embodiment of the present invention, a control motor 17 is fixedly mounted on the upper end surface of the carrier 14 , and a transmission sleeve 16 is fixedly mounted on the output shaft of the control motor 17 . The control motor 17 is a common waterproof motor used to control the rotation of the transmission sleeve 16 .

[0055] One end of the transmission shaft 19 extends to the inner cavity of the transmission sleeve 16 and is fixedly mounted with a transmission platform 29 . Rotating the transmission platform 29 drives the transmission shaft 19 to rotate synchronously.

[0056] A transmission bevel block 34 is fixedly mounted on the outer wall of the transmission platform 29, and a transmission bevel plate 35 for pressing the transmission bevel block 34 is elastically mounted on the inner wall of the transmission sleeve 16. Through the cooperation of the transmission bevel block 34 and the transmission bevel plate 35, one-way transmission of the transmission sleeve 16 and the transmission platform 29 is achieved.

[0057] During the process of injecting sewage into the flocculation tank 1, since the sewage in the flocculation tank 1 has not reached the required liquid level, the external aeration pump is not working at this time. In order to facilitate the scraping of flocculants on the outer wall of the filter cylinder 15 at this time, the transmission sleeve 16 is driven to rotate by the control motor 17, which serves as the power source for the rotation of the transmission shaft 19.

[0058] When there is no aeration, the control motor 17 controls the transmission platform 29 to rotate, and the guide bevel block 31 and the guide bevel plate 32 slip. During aeration, the transmission shaft 19 is controlled to rotate through the cooperation of the protrusion and the spiral groove 26, and the transmission bevel block 34 and the transmission bevel plate 35 slip to prevent mutual interference of transmission.

[0059] As a preferred embodiment of the present invention, a mounting transverse plate 37 is fixedly installed on the inner wall of the flocculation tank 1, a mounting platform 40 is elastically installed on the bottom surface of the mounting transverse plate 37, a spring is provided on the upper end surface of the mounting platform 40, and the other end of the spring is connected to the mounting transverse plate 37.

[0060] The upper end surface of the installation horizontal plate 37 is fixedly mounted with a top-pressing arc plate 36 , the outer wall of the top-pressing arc plate 36 is in contact with the outer wall of the filter cartridge 15 , the middle part of the top-pressing arc plate 36 is convex upward, and the filter cartridge 15 is made of elastic material.

[0061] The bottom surface of the pressing arc plate 36 is fixedly connected to the upper end surface of the mounting platform 40 through a connecting rod. After the mounting platform 40 is moved, the spring reset drives the mounting platform 40 and the pressing arc plate 36 to perform simple harmonic motion synchronously, so that the pressing arc plate 36 presses the filter cartridge 15 upward reciprocatingly, causing the filter cartridge 15 to bulge upward. In the process of the filter cartridge 15 bulging upward, the material guiding spiral plate 18 scrapes the filter cartridge 15 to improve the cleaning efficiency, so as to separate the flocculants from the filter cartridge 15.

[0062] A mounting rod 38 is rotatably installed on the inner wall of the flocculation tank 1, and a transmission arc plate 33 for pressing the mounting platform 40 is fixedly installed on the outer wall of the mounting rod 38. The transmission arc plate 33 is made of elastic material, and the middle part is bent. Pressing one end of the mounting rod 38 drives the transmission arc plate 33 to move, thereby pressing the mounting platform 40 downward to slide. At this time, the spring outside the mounting platform 40 stores elastic potential energy. As the mounting rod 38 deflects, the transmission arc plate 33 and the mounting platform 40 are separated. At this time, the spring releases the elastic potential energy to control the movement of the mounting platform 40 and the pressing arc plate 36.

[0063] After the transmission arc plate 33 and the mounting platform 40 are separated, the mounting rod 38 is controlled to rotate in the opposite direction. At this time, the arc surface of the transmission arc plate 33 contacts the outer wall of the mounting platform 40, so that the transmission arc plate 33 can move to the top of the mounting platform 40 again, thereby facilitating the installation and pressing of the mounting platform 40 again.

[0064] The mounting rod 38 is located within the moving track of the storage barrel 3 . When the mounting frame 4 rotates, the storage barrel 3 presses the mounting rod 38 downward to deflect it, so as to facilitate the transmission arc plate 33 to press the mounting platform 40 .

[0065] In order to increase the speed of resetting the mounting rod 38 after pressing the mounting rod 38, a float 39 is fixedly installed at one end of the mounting rod 38. The float 39 is a foam ball (the density of which is not higher than the density of the sewage in the flocculation tank 1). The upward buoyancy of the float 39 can increase the resetting speed of the mounting rod 38, so that the transmission arc plate 33 can move to the top of the mounting platform 40 again.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
