Description

Technical Field

[0001] The present invention relates to the technical field of water pollution treatment, and specifically relates to an industrial wastewater zero-discharge treatment device. Background Art

[0002] In the prior art, wastewater treatment uses physical, chemical, and biological methods to treat wastewater, purify the wastewater, reduce pollution, and even achieve wastewater recycling and reuse to make full use of water resources. Currently, during industrial production, wastewater needs to be treated, and the treatment of wastewater first requires filtering impurities in the wastewater.

[0003] For example, in a Chinese patent with the publication number CN220618606U and the name "An Industrial Wastewater Zero-Discharge Treatment Device", it includes a housing and a tank body. The tank body is located above the housing. A driving component is provided inside the tank body. A second motor is fixedly connected to the top end of the tank body. The transmission shaft of the second motor is fixedly connected to a stirring rod, and several stirring blades are fixedly connected to the outer side of the stirring rod. The beneficial effect of the present invention is that: the second motor facilitates driving several stirring blades to rotate, facilitating stirring of the sewage after adding a coagulant aid, accelerating the precipitation of its contaminants. Through the interception of the contaminant interception net, it prevents contaminants from blocking the inlet hose. At the same time, through the water pump, the precipitated sewage is conveniently pumped out of the interior of the tank body via the inlet hose and the outlet pipe, and then the pumped precipitated wastewater undergoes subsequent processing operations such as reverse osmosis separation, evaporation and crystallization to form solids for centralized treatment or recycling, achieving the effect of zero discharge.

[0004] Although an industrial wastewater zero-discharge treatment device in the above patent is practical and convenient, it also has deficiencies. The above patent filters with a contaminant interception net. The contaminant interception net is arranged inside the tank body, which is inconvenient for cleaning impurities on the contaminant interception net. Excessive impurities in the wastewater easily cause the contaminant interception net to become blocked, having a certain impact on wastewater filtration. Summary of the Invention

Detailed implementation manners

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0028] Please refer to Figures 1-9, a technical solution provided by an embodiment of the present invention: The industrial wastewater zero-discharge treatment device includes a filter cylinder 1, a slag storage cylinder 2 arranged on one side of the filter cylinder 1, a transmission assembly, a linkage assembly, and a trigger assembly. A circular plate 13 is vertically slidably connected in the filter cylinder 1. During the process of the circular plate 13 vertically moving upward relative to the filter cylinder 1, it has a horizontal position above the filter cylinder 1. A plurality of filtering mechanisms are hinged inside the circular plate 13. The circular plate 13 is vertically moved upward to the horizontal position through the transmission assembly. After the circular plate 13 is vertically moved upward to the horizontal position, the circular plate 13 is horizontally slidably connected in the slag storage cylinder 2 through the linkage assembly. The trigger assembly receives the drive of the horizontal sliding of the circular plate 13 to make each filtering mechanism rotate downward so that impurities slide into the slag storage cylinder 2. Specifically, the setting of the slag storage cylinder 2 can separate the impurity treatment area from the filtering area, which is convenient for subsequent centralized cleaning or discharging. A sludge discharge valve can be arranged in the slag storage cylinder 2 for discharging slag. And preferably, a plurality of water guns can be arranged in the slag storage cylinder 2 to perform reverse flushing on the impurities remaining on each filtering mechanism to improve the cleaning effect. The filtering area and the cleaning area are separated, which is convenient for separately replacing filter materials or repairing components.

[0029] As a preferred technical solution, the transmission mechanism includes a column 3, a screw rod 5, a sleeve 6, a slider 7, a sleeve 10, and a connecting plate 11. The column 3 is arranged on one side of the filter cylinder 1. The screw rod 5 is rotatably connected inside the column 3. The sleeve 10 is movably connected to the column 3. A sleeve 6 is connected to the screw rod 5. One side of the sleeve 6 is fixedly connected with a slider 7. A vertical chute 8 is vertically opened on the column 3. The slider 7 is vertically slidably connected in the vertical chute 8. The top of the slider 7 is fixedly connected to the bottom of the sleeve 10. A connecting plate 11 is fixedly connected to the circumferential side surface of the sleeve 10. One end of the connecting plate 11 away from the sleeve 10 is vertically and fixedly connected with a bracket 12. The bottom end of the bracket 12 is fixedly connected to the top of the circular plate 13. Specifically, a motor 4 is arranged inside the column 3. The output end of the motor 4 is coaxially and fixedly connected to the bottom end of the screw rod 5. Starting the motor 4, the motor 4 drives the screw rod 5 to rotate. Since the vertical chute 8 restricts the circumferential rotation of the slider 7, the slider 7 can only linearly move upward along the length direction of the vertical chute 8. The sleeve 6 is driven to vertically move upward through the screw drive of the screw rod 5. At the same time, the slider 7 drives the sleeve 10 to vertically move upward. The circular plate 13 is driven to move upward synchronously through the connecting plate 11 and the bracket 12, so that each filtering mechanism is vertically moved upward to the horizontal position, and the impurities in the wastewater are lifted and moved to the upper side of the filter cylinder 1.

[0030] As a preferred technical solution, the linkage assembly includes an arc-shaped chute 9. A horizontal arc-shaped chute 9 is provided on the column 3. The arc-shaped chute 9 communicates with the vertical chute 8. The slider 7 is slidably connected to the arc-shaped chute 9. Specifically, when the slider 7 moves vertically upward to the horizontal working position, at this time, the top of the slider 7 abuts against the upper groove wall of the vertical chute 8, and the slider 7 cannot move upward anymore. At this time, the screw rod 5 is rotated again, and the slider 7 is driven to rotate through the kit 6, so that the slider 7 slides in the arc-shaped chute 9, and the annular plate 13 is driven to rotate horizontally synchronously through the connecting plate 11 and the bracket 12, so that each filtering mechanism rotates around the axis of the screw rod 5 into the slag storage cylinder 2, which is convenient for subsequently pouring the impurities on the filtering mechanism into the slag storage cylinder 2.

[0031] As a preferred technical solution, each filtering mechanism includes a first filter plate 14 and a second filter plate 15. One side of the first filter plate 14 and the second filter plate 15 are respectively fixedly connected with a first rotating sleeve 16 and a second rotating sleeve 29. The first rotating sleeve 16 and the second rotating sleeve 29 are both hinged to the annular plate 13. Specifically, a plurality of rotating shafts 28 are circumferentially and arrayedly distributed on the annular plate 13. Each first rotating sleeve 16 and each first rotating sleeve 16 are rotatably sleeved on the corresponding rotating shafts 28. Specifically, the first filter plates 14 can be divided into an odd filter plate group, and the second filter plates 15 can be divided into an even filter plate group.

[0032] As a preferred technical solution, the triggering assembly includes a plurality of driving mechanisms, a first arc-shaped gear ring 26, and a second arc-shaped gear ring 27 meshing with the first arc-shaped gear ring 26. The first rotating sleeve 16 is provided with a plurality of first spiral grooves 19 in a circumferential array, and the second rotating sleeve 29 is provided with a plurality of second spiral grooves 31 in a circumferential array. A driving ring 17 is rotatably connected inside the annular plate 13. The first arc-shaped gear ring 26 is horizontally arranged on one side of the driving ring 17, and the second arc-shaped gear ring 27 is horizontally arranged on the inner wall of the slag storage cylinder 2. Each driving mechanism includes a first driving member and a second driving member. The first driving member includes a plurality of first protrusions 18, and the second driving member includes a plurality of second protrusions 30. Each first protrusion 18 is slidably connected to a corresponding first spiral groove 19 one by one, and each second protrusion 30 is slidably connected to a corresponding second spiral groove 31 one by one. Specifically, when the annular plate 13 slides horizontally in the slag storage cylinder 2, the first arc-shaped gear ring 26 and the second arc-shaped gear ring 27 are meshed and driven to drive the driving ring 17 to rotate horizontally. Moreover, a through hole for the driving ring 17 to pass through is provided in each rotating shaft 28. In the initial state, the first first protrusion 18 of the first driving member close to the rotating shaft 28 fits with the corresponding first spiral groove 19 to lock the corresponding first rotating sleeve 16, so that the first filter plate 14 is kept horizontal. Each first protrusion 18 sequentially slides and cooperates with the corresponding first spiral groove 19 to drive each first filter plate 14 to rotate downward and unfold. Similarly, each second protrusion 30 sequentially slides and cooperates with the corresponding second spiral groove 31 to drive each second filter plate 15 to rotate downward and unfold, so that impurities slide from each first filter plate 14 and the second filter plate 15 into the slag storage cylinder 2, effectively preventing blockage caused by excessive impurities and affecting the filtration of wastewater. It does not rely on an electronic or hydraulic system, is suitable for the wastewater environment, and precisely matches the unlocking timing with the rotation speed of the driving ring 17 to ensure the reliability and efficiency of the staged unfolding. Preferably, a groove 32 is provided in the filter cylinder 1, and the annular plate 13 is slidably connected vertically in the groove 32. The groove 32 plays a role of guiding and limiting, and a blind hole communicating with the groove 32 is also vertically provided in the filter cylinder 1. The first arc-shaped gear ring 26 is slidably connected vertically in the blind hole, which can prevent the first arc-shaped gear ring 26 from driving the driving ring 17 to rotate during filtration, causing each first filter plate 14 and the second filter plate 15 to unfold, and the impurities are discharged together with the already filtered wastewater.

[0033] As a preferred technical solution, a plug rod 24 is vertically inserted into each second rotating sleeve 29, a contact rod 21 is vertically abutted against each first rotating sleeve 16, an arc-shaped block 20 is provided on the circumferential side of each first rotating sleeve 16, and each arc-shaped block 20 is in sliding contact with each contact rod 21 in a one-to-one correspondence. One end of each arc-shaped block 20 close to the corresponding contact rod 21 is inclined. The tops of each contact rod 21 and the tops of the plug rods 24 adjacent to the rotation direction of the driving ring 17 are fixedly connected together with a connecting rod 23. Specifically, the process of unfolding the filtering mechanism can be divided into pre-unfolding and main unfolding. The number of first protrusions 18 in each first driving member is one more than the number of second protrusions 30 in the corresponding second driving member. The driving ring 17 drives each first protrusion 18 to rotate. When the first first protrusion 18 of the first driving member close to the rotating shaft 28 is in sliding fit with the corresponding spiral groove, the first rotating sleeve 16 is driven to rotate by a certain angle. At this time, the first second protrusion 30 of the second driving member close to the rotating shaft 28 is in contact with the corresponding second spiral groove 31. The first rotating sleeve 16 drives the arc-shaped block 20 to rotate, and the arc-shaped block 20 drives the contact rod 21 to move upward. Through the connecting rod 23, the plug rod 24 is moved upward, which not only releases the locking of the second rotating sleeve 29, but also makes each first filter plate 14 pre-unfold by a certain angle first, releasing the initial adhesion or impurity extrusion between adjacent second filter plates 15, and creating a clearance space for the subsequent unfolding of the second filter plates 15. The odd-numbered filter plate groups and the even-numbered filter plate groups are unfolded at intervals of 0.3 - 0.5 seconds, which can reduce the instantaneous space competition. Subsequently, the driving ring 17 continues to rotate, so that each first filter plate 14 and second filter plate 15 rotate downward to unfold, and further expand the angle on the basis of the pre-unfolding for main unfolding. At this time, the filter plate trajectory has avoided the interference area, so that impurities slide from each first filter plate 14 and second filter plate 15 into the slag storage cylinder 2. And the small-scale pre-unfolding can release loose particles or low-viscosity impurities, reducing the resistance during the main unfolding. The large-angle main unfolding combined with the water gun flushing is used to forcibly strip the viscous sludge or fiber impurities, and the impurities directly fall into the slag storage cylinder 2, avoiding the splashing or volatilization of harmful substances. When each first filter plate 14 and second filter plate 15 are unfolded, the entangled fibers are forcibly separated to avoid blockage.

[0034] As a preferred technical solution, a spring 22 is sleeved on each plug rod 24 and contact rod 21. Specifically, the two ends of the spring 22 are fixedly connected to the bottom of the connecting rod 23 and the top of the annular plate 13 respectively. During the reset process, the plug rod 24 and the contact rod 21 can be driven to move vertically downward by the spring 22 to reset to the initial state.

[0035] As a preferred technical solution, an arc-shaped limiting groove 25 is horizontally opened on the circumferential side of the annular plate 13, and the first arc-shaped gear ring 26 is slidably connected in the limiting groove 25. Specifically, the limiting groove 25 plays a guiding role to avoid causing movement interference to the first arc-shaped gear ring 26.

[0036] Working principle: There is an inlet pipe connected to the top of the filter cartridge 1, and a drain pipe is opened on one side of the filter cartridge 1. The wastewater generated by the industry is poured into the filter cartridge 1 through the inlet pipe, and is discharged from the drain pipe after being filtered by the filter cartridge 1. The filtered impurities remain on the filter mechanism. When it is necessary to remove the impurities on the filter mechanism to avoid clogging, the first filter plates 14 and the second filter plates 15 isolate the impurities in the wastewater, start the motor 4, and the motor 4 drives the screw 5 to rotate. The screw drive assembly 6 moves vertically upward through the spiral transmission of the screw 5. At the same time, the slider 7 drives the sleeve 10 to move vertically upward, and drives the annular plate 13 to move upward synchronously through the connecting plate 11 and the bracket 12. The filter mechanism is moved vertically upward to the horizontal position, and the impurities in the wastewater are lifted and moved to the upper side of the filter cylinder 1. Then the screw 5 is rotated again, and the slider 7 is driven to rotate through the kit 6, so that the slider 7 slides in the arc chute 9, and the annular plate 13 is driven to rotate horizontally synchronously through the connecting plate 11 and the bracket 12, so that each filter mechanism is rotated around the axis of the screw 5 to the slag storage cylinder 2, so that the impurities on the filter mechanism can be poured into the slag storage cylinder 2. Then, when the annular plate 13 slides horizontally in the slag storage cylinder 2, the first arc gear ring 26 is meshed with the second arc gear ring 27 to drive the drive ring 17 to rotate horizontally, and the drive ring 17 drives each first The protrusion 18 rotates, and when the first protrusion 18 of the first driving member close to the rotating shaft 28 slides with the corresponding spiral groove, the first rotating sleeve 16 is driven to rotate a certain angle. At this time, the first second protrusion 30 of the second driving member close to the rotating shaft 28 is fitted with the corresponding second spiral groove 31, and the first rotating sleeve 16 drives the arc block 20 to rotate, and the arc block 20 drives the abutment rod 21 to move upward, and the insertion rod 24 is moved upward through the connecting rod 23, which not only releases the lock of the second rotating sleeve 29, but also makes each first filter plate 14 pre-expand a certain angle, releasing the initial adhesion or impurity extrusion between the adjacent second filter plate 15, and preparing for the subsequent second filter plate 15 is unfolded to make room for avoidance and reduce instantaneous space competition. Subsequently, the driving ring 17 continues to rotate, and each first protrusion 18 is slidably matched with the corresponding first spiral groove 19 in turn, driving each first filter plate 14 to rotate and unfold downward. Similarly, each second protrusion 30 is slidably matched with the corresponding second spiral groove 31 in turn, driving each second filter plate 15 to rotate and unfold downward, so that impurities slide from each first filter plate 14 and second filter plate 15 into the residue storage barrel 2, which is convenient for cleaning the first filter plate 14 and second filter plate 15. The first filter plate 14 and second filter plate 15 can be washed with high pressure to effectively prevent blockage caused by excessive impurities and affect the filtration of wastewater.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
