Description

Technical Field

[0001] This invention relates to the field of battery manufacturing and processing technology, and in particular to a high-efficiency wastewater treatment device for battery manufacturing and processing. Background Technology

[0002] Wastewater from battery production is characterized by complex pollutants, including a variety of harmful substances. Combining physical, chemical, and biological multi-stage treatment technologies, by leveraging their respective advantages, can more effectively remove various pollutants from wastewater, improve treatment efficiency, reduce environmental pollution, comply with environmental regulations, and promote the green and sustainable development of the battery industry.

[0003] The production and processing of batteries generates a large amount of wastewater containing heavy metal ions, organic matter, and other pollutants. If discharged directly without treatment, it will cause serious environmental pollution. Therefore, wastewater treatment is crucial for battery manufacturers.

[0004] Filtration is a common physical method for treating wastewater generated during battery production and processing. It is mainly used to remove solid impurities from wastewater. However, when using filtration to treat wastewater generated during battery production and processing, problems such as incomplete filtration, clogging of the filter media affecting the normal use of the filtration equipment, and inability to achieve multi-stage filtration of wastewater are common.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by the present invention compared with the prior art are as follows:

[0018] The invention features a primary treatment mechanism and a subsequent treatment mechanism that work together to achieve multi-stage treatment of solid impurities in wastewater generated during battery production. By treating solid impurities in wastewater in stages and at multiple levels, it is ensured that solid impurities in wastewater are completely removed, thereby improving the filtration effect on solid impurities in wastewater generated during battery production and significantly improving the overall filtration efficiency.

[0019] The present invention features a brush, a gear, and a toothed ring. The continuous rotation of the water outlet cylinder drives the brush to rotate, while the gear and toothed ring allow the brush to rotate independently during this process. This achieves the purpose of cleaning the solid impurities that are intercepted and attached to the inner wall of the filter cartridge, preventing the filtered solid impurities from adhering to the inner wall of the filter cartridge for a long time without being cleaned in time, which would cause blockage of several filter holes in the filter cartridge and affect the filtration function of the filter cartridge.

[0020] The turbine plate, arc-shaped filter plate one, helical gear disk one, helical gear one, screw rod one, arc-shaped filter plate two, helical gear disk two, helical gear two, and screw rod two of this invention enable the device to achieve a more complete multi-stage filtration of solid impurities in wastewater. At the same time, it can transport the cleaned solid impurities in the wastewater inside the device to the outside of the device, thereby achieving self-cleaning of the solid impurities in the wastewater remaining inside the device after filtration. This prevents solid impurities from accumulating in the device for a long time, which would affect the normal use of the device and increase the difficulty and cost of daily maintenance.

[0021] The arc-shaped filter plate 2 and the through pipe of this invention enable the recirculation of some sewage that remains between filter cylinder 1 and the outlet cylinder but has not passed through filter cylinder 1, preventing sewage from stagnating in the device. The arc-shaped filter plate 2 allows this sewage to complete the filtration of solid impurities during the recirculation process, thereby reducing the amount of solid impurities in the recirculated sewage. When the recirculated sewage is drawn out again and thrown towards filter cylinder 1, the filtration burden of filter cylinder 1 can be greatly reduced.

[0022] The baffle plate in this invention allows wastewater to flow into the chute shell through the outlet pipe. The wastewater first flows between the baffle plate and the chute shell, acting as a barrier, buffer, and height limiter. This prevents excessive impact from the wastewater flowing directly into the chute shell, which could increase the risk of overflow and overloading the filter cartridge. Simultaneously, the baffle plate guides the water flow, preventing wastewater from directly entering the chute shell, especially at the inlet where irregular flow patterns can occur, leading to localized high flow rates and large volumes. The baffle plate's blocking and guiding effect ensures that the wastewater flows uniformly towards the filter cartridge, maintaining the same width as the inside of the chute shell. This even flow through the filter cartridge improves its filtration efficiency and prevents overloading in localized areas. Attached Figure Description

[0040] The primary treatment mechanism 4 also includes a gear ring 412 fixedly connected to the inner wall of the filter cartridge 43, and gears 411 fixedly connected to the outer walls of the two brushes 49, with the outer walls of the two gears 411 meshing with the outer walls of the gear ring 412.

[0041] The primary treatment mechanism 4 includes a water pump 414 fixedly connected to the inner wall of the base 2. A water pump 414 has a water pump pipe 415 fixedly connected to its input end and a delivery pipe 416 fixedly connected to its output end. The outer wall of the water pump pipe 415 is fixedly connected to the inner wall of the base 2. The outer wall of the delivery pipe 416 is fixedly connected to the inner wall of the connecting shell 3. The inner wall of the treatment shell 1 and the inner wall of the base 2 are both fixedly connected to an inlet pipe 413. Several interconnecting shells 417 are fixedly connected in an arc-shaped array on the inner wall of the connecting shell 3. Arc-shaped filter plates 418 are fixedly connected to the inner walls of the several interconnecting shells 417.

[0042] The primary processing mechanism 4 also includes a rotating rod 420 that is rotatably connected to the inner wall of the base 2 and the inner wall of the connecting outer shell 3. A turbine plate 419 is fixedly connected to the outer wall of the rotating rod 420. A helical gear disk 421 is fixedly connected to the outer wall of the rotating rod 420. A number of spiral rods 423 are rotatably connected to the inner walls of the connecting outer shell 417. A helical gear 422 is fixedly connected to the outer walls of the helical rods 423. The outer walls of the helical gears 422 are meshed with the outer walls of the helical gear disk 421.

[0043] The primary treatment mechanism 4 also includes several interconnected outer shells 425 arranged in an arc-shaped array and fixedly connected to the inner wall of the base 2 and the inner wall of the treatment outer shell 1. Several through pipes 424 are arranged in an arc-shaped array and connected to the top of the base 2. The bottom of the through pipes 424 on the same side is connected to the outer wall of the interconnected outer shell 425. Arc-shaped filter plates 426 are fixedly connected to the inner walls of the interconnected outer shells 425. Through pipes 4210 are connected to the outer walls of the interconnected outer shells 425 and the outer walls of the interconnected outer shell 1 417 on the same side. The outer walls of the through pipes 4210 are fixedly connected to the inner wall of the connecting outer shell 3.

[0044] The primary processing mechanism 4 also includes a helical gear disk 427 fixedly connected to the outer wall of the rotating rod 420, a helical rod 429 rotatably connected to the inner wall of several connecting outer shells 425, a helical gear 428 fixedly connected to the outer wall of several helical rods 429, and a helical gear 428 meshing with the outer wall of several helical gears 428.

[0045] The aforementioned helical tooth disk 421 and helical tooth disk 427 are symmetrically arranged, with the helical tooth disk 421 having its teeth facing upwards and the helical tooth disk 427 having its teeth facing downwards.

[0046] The aforementioned base 2, turbine plate 419, and rotating rod 420 form a mature turbine structure in the prior art;

[0047] The two brushes 49 and the two perforated plates 42 are installed directly opposite each other;

[0048] Both motors 45 mentioned above are servo motors, which are mature technologies in the existing technology. This solution only uses their function of controlling the rotation speed, number of rotations and start / stop at any time, and will not elaborate on their structure and working principle.

[0049] In a specific implementation of the present invention, the device is placed in a suitable position to treat the wastewater generated during the production of storage batteries. Two motors 45 are turned on to drive two rotating shafts 46 to rotate, which in turn drives two gears 47 to rotate, which in turn drives two gear rings 44 to rotate, thereby making the water cylinder 41 continuously rotate.

[0050] An external water pump pumps the wastewater to be treated into the base 2 through the inlet pipe 413. The water pump 414 is turned on to pump the wastewater out of the base 2 through the pumping pipe 415 and transport it to the connecting shell 3 through the delivery pipe 416. The wastewater entering the connecting shell 3 will enter several connecting shells 417 through the openings, and then pass through several arc-shaped filter plates 418 into the space between the connecting shell 3 and the outlet cylinder 41. During this process, the several arc-shaped filter plates 418 will perform preliminary filtration of solid impurities in the wastewater.

[0051] The pre-filtered wastewater entering the space between the outer casing 3 and the outlet cylinder 41 will enter several holes opened at the top of the outlet cylinder 41. At this time, the outlet cylinder 41 is in a continuous rotating state, which will continuously throw the wastewater into it through several perforated plates 42 towards the filter cylinder 43. The thrown wastewater will pass through the filter cylinder 43 and enter the space between the filter cylinder 43 and the treatment outer casing 1, and fall on the top of the base 2 under the action of gravity. Then it will flow out through the outlet pipe 48 into the subsequent treatment mechanism 5. The solid impurities in the wastewater will be intercepted and filtered in the inner wall of the filter cylinder 43, thereby achieving further filtration of solid impurities in the wastewater after filtration treatment.

[0052] The continuous rotation of the water outlet cylinder 41 will cause both brushes 49 to rotate around the inner wall of the filter cylinder 43, thereby cleaning the solid impurities that are intercepted and attached to the inner wall of the filter cylinder 43. This prevents the filtered solid impurities from being attached to the inner wall of the filter cylinder 43 for a long time without being cleaned in time, which would cause blockage of several filter holes in the filter cylinder 43 and affect the filtration function of the filter cylinder 43.

[0053] When the water outlet cylinder 41 rotates continuously, it drives the two brushes 49 to rotate around the inner wall of the filter cylinder 43. The two gears 411 mesh with the gear ring 412 and rotate, so that the two brushes 49 rotate independently. This helps to improve the efficiency and effectiveness of the two brushes 49 in cleaning the solid impurities attached to the inner wall of the filter cylinder 43.

[0054] Based on the installation positions of the two brushes 49 inside the water outlet cylinder 41, the sewage entering the water outlet cylinder 41 is thrown out through several perforated plates 42. Therefore, the sewage thrown out from the two perforated plates 42 corresponding to the installation positions of the two brushes 49 will be thrown onto the two brushes 49. During this process, the sewage will be sprayed, which will impact the bristles of the brushes 49 and help the solid impurities attached to the bristles of the brushes 49 due to the cleaning of the inner wall of the filter cartridge 43 by the brushes 49 to be better separated and removed, thereby achieving the cleaning purpose of the brushes 49.

[0055] When the sewage is thrown out towards the filter cartridge 43, some sewage will fail to pass through the filter cartridge 43 and remain between the filter cartridge 43 and the outlet cartridge 41. Under the action of gravity, the sewage will eventually fall to the top of the base 2, and then flow into the connected outer shell 425 through several through pipes 424, and further flow into the base 2 to merge with the sewage pumped into the base 2. Then the pump 414 is turned on to pump the sewage that has entered the base 2 out again. In this way, the sewage return and extraction are realized, which helps to improve the efficiency of sewage treatment of this device and prevent sewage stagnation.

[0056] During this process, when the sewage flows towards the several through pipes 424, it can carry the solid impurities that have been cleaned off the inner wall of the filter cartridge 43 and fallen on the top of the base 2 into the several through pipes 424 and finally into the several connecting shells 425. The solid impurities in the sewage that enter the several connecting shells 425 will be intercepted and filtered by the several arc-shaped filter plates 426, while the sewage will pass through the connecting shells 425 and flow into the base 2. This not only prevents the solid impurities in the sewage from accumulating on the top of the base 2, but also reduces the amount of solid impurities in the sewage that flows back into the base 2 because they have been filtered. When the sewage that flows back is drawn out again and thrown out towards the filter cartridge 43, the filtration burden of the filter cartridge 43 can be greatly reduced.

[0057] The sewage pumped by the external pump into the connecting housing 3 continuously impacts the turbine plate 419, causing the turbine plate 419 to rotate. This, in turn, drives the rotating rod 420 to rotate, which in turn drives the helical gear disk 421 to rotate, which in turn drives several helical gears 422 to rotate, which in turn drives several spiral rods 423 to rotate. Solid impurities in the sewage that are filtered and intercepted in several arc-shaped filter plates 418 are continuously transported to several pipes 4210, so that the solid impurities eventually enter the connecting housing 425 through several pipes 4210 and are intercepted in several arc-shaped filter plates 426.

[0058] The rotation of the rotating rod 420 drives the helical gear disk 427 to rotate, which in turn drives several helical gears 428 to rotate, which in turn drives several spiral rods 429 to rotate. This continuously transports solid impurities within several arc-shaped filter plates 426 away from the helical gear disk 427, and finally transports them to the outside of the treatment housing 1. This achieves self-cleaning of solid impurities in the filtered wastewater remaining in the device, preventing solid impurities from accumulating in the device for a long time, affecting the normal use of the device, and increasing the difficulty and cost of daily maintenance.

[0059] Example 2, as Figure 10 - Figure 12 As shown, the subsequent processing mechanism 5 includes a chute housing 51 fixedly connected to the inner wall of the processing housing 1, a baffle plate 52 fixedly connected to the inner wall of the chute housing 51, a filter cartridge 53 rotatably connected to the inner wall of the chute housing 51, a brush 54 rotatably connected to the inner wall of the chute housing 51, a drive assembly 55 provided on the inner wall of the processing housing 1, and a collection box 56 slidably connected to the outer wall of the chute housing 51. The inner wall of the collection box 56 is provided with a plurality of filter holes 57.

[0060] The drive assembly 55 includes a second water pump 552 fixedly connected to the inner wall of the processing housing 1. A third extraction pipe 558 is fixedly connected to the input end of the second water pump 552. A second delivery pipe 556 is fixedly connected to the output end of the second water pump 552. The outer wall of the second delivery pipe 556 is fixedly connected to the inner wall of the processing housing 1. A mounting box 554 is fixedly connected to the inner wall of the processing housing 1. A second extraction pipe 553 is fixedly connected to the inner wall of the mounting box 554 and the inner wall of the processing housing 1. A turbine rod 555 is rotatably connected to the inner wall of the mounting box 554. A third bevel gear 557 is fixedly connected to the outer wall of the turbine rod 555 and the outer wall of the filter cartridge 53. The two third bevel gears 557 are meshed at their outer walls. A third gear 551 is symmetrically fixedly connected to the outer wall of the filter cartridge 53 and the outer wall of the brush 54. The third gear 551 on the same side is meshed at their outer walls.

[0061] The multi-stage processing mechanism 6 includes several trapezoidal filter layers 61 that are fixedly connected to the inner wall of the processing housing 1. A multi-stage processing box 62 is fixedly connected to the outer wall of the conveying pipe 2 556. Several inclined filter layers 63 are fixedly connected to the inner wall of the multi-stage processing box 62. A flange pipe 64 is fixedly connected to the inner wall of the multi-stage processing box 62.

[0062] The volume of solid impurities in the wastewater generated during battery production is decreasing sequentially from the arc-shaped filter plate 418, filter cartridge 43, and filter cartridge 53.

[0063] The filter holes on filter cartridge 43 and arc-shaped filter plate 426 are of the same specifications, and the filter holes and several filter holes 57 on filter cartridge 53 are of the same specifications.

[0064] The aforementioned turbine rod 555 and mounting box 554 form a mature turbine structure in the prior art;

[0065] The aforementioned connection between the first connecting outer shell 417 and the first screw rod 423 on the same side, and the connection between the second connecting outer shell 425 and the second screw rod 429, both constitute the screw conveying structure in the prior art.

[0066] The trapezoidal filter layer 61 mentioned above is an activated carbon filter layer, which is a mature technology in the prior art. This invention only uses it to effectively adsorb organic pollutants, odors and toxic gases in the wastewater generated in the production of storage batteries, and will not elaborate on its structure and working principle.

[0067] The aforementioned inclined filter layers 63 are arranged from top to bottom as an oxidation-reduction reaction layer and a biofilm. The oxidation-reduction reaction layer and the biofilm are arranged alternately. The oxidation-reduction reaction layer mainly uses oxidants to oxidize organic and inorganic pollutants in wastewater into substances that are easier to treat or harmless. The biofilm allows microorganisms on the membrane to adsorb and degrade organic matter in the water, especially those organic pollutants that are difficult to degrade, when wastewater passes through. The biofilm provides a stable environment in which microorganisms can reproduce stably for a long time, thereby continuously degrading organic matter. These are all mature technical means in the existing technology. The structure and working principle of this solution will not be elaborated further here.

[0068] In a specific implementation of this invention, wastewater after filtration by the primary treatment mechanism 4 flows through the outlet pipe 48 to the position between the chute housing 51 and the baffle plate 52. When the wastewater accumulates to a height exceeding the baffle plate 52, the water flow will pass over the baffle plate 52 and flow towards the filter cartridge 53. The baffle plate 52 serves to block, buffer, and limit the height, preventing excessive impact from the wastewater flowing directly into the chute housing 51 through the outlet pipe 48, thus reducing the risk of wastewater overflow and increasing the filtration burden on the filter cartridge 53. Simultaneously, the baffle plate 52 can... The baffle plate 52 serves to guide the water flow and prevent sewage flowing out of the outlet pipe 48 from flowing directly into the chute shell 51, especially at the inlet, where the water flow is prone to form irregular flow lines, resulting in local water flow speed and local flow rate. Under the blocking and guiding effect of the baffle plate 52, the sewage can become uniform and equal in width to the inside of the chute shell 51 when it flows towards the filter cartridge 2 53. This allows the water to flow evenly through the filter cartridge 2 53, which is beneficial to improving the filtration efficiency of the filter cartridge 2 53 and preventing local overload of the filter cartridge 2 53.

[0069] Wastewater flows continuously towards filter cartridge 2 53 inside the chute housing 51 after passing through baffle plate 52, and then enters the treatment housing 1 through filter cartridge 2 53. During this process, filter cartridge 2 53 further filters the wastewater that has already been filtered.

[0070] When the second water pump 552 is turned on, the filtered sewage that has entered the treatment housing 1 is drawn out through the second extraction pipe 553 and finally transported out through the second delivery pipe 556. During this process, the sewage that enters the second extraction pipe 553 will enter the installation box 554 and cause continuous impact on the turbine rod 555, causing the turbine rod 555 to rotate, thereby driving the third bevel gear 557 to rotate, which in turn drives another bevel gear 557 to rotate, thereby driving the second filter cartridge 53 to rotate. This helps to prevent the second filter cartridge 53 from remaining stationary, where impurities from the sewage can easily accumulate in the same position and cause blockage of the second filter cartridge 53.

[0071] The rotation of filter cartridge 2 53 drives the two gears 3 551 fixed on filter cartridge 2 53 to rotate, which in turn drives the two gears 3 551 fixed on brush 2 54 to rotate, thereby driving brush 2 54 to rotate continuously, cleaning solid impurities on filter cartridge 2 53. The rotation direction of brush 2 54 is opposite to that of filter cartridge 2 53, which helps to keep the surface of filter cartridge 2 53 clean, prevent clogging, and ensure the long-term efficient operation of the subsequent processing mechanism 5.

[0072] The solid impurities cleaned off from filter cartridge 2 53 will eventually enter the collection box 56. The collection box 56 can be removed from the slide shell 51 to clean the solid impurities inside.

[0073] The arrangement of several filter holes 57 allows the wastewater to enter the collection box 56, which not only filters out solid impurities in the wastewater, but also allows the wastewater to exit and eventually flow into the processing shell 1 to be extracted.

[0074] When wastewater flows into the treatment shell 1 through filter cartridge 2 53, it first flows through several trapezoidal filter layers 61. During this process, the trapezoidal filter layers 61 adsorb organic pollutants, odors, and toxic gases in the wastewater, thereby treating the wastewater. The wastewater flowing out of filter cartridge 2 53 first flows to the horizontal part of the trapezoidal filter layers 61. The design of the shape of the trapezoidal filter layers 61 allows the wastewater to continue flowing to the side walls of the trapezoidal filter layers 61 when it flows into the horizontal part of the trapezoidal filter layers 61, thereby increasing the contact area between the wastewater and the trapezoidal filter layers 61. This is beneficial to the adsorption and treatment effect of the trapezoidal filter layers 61 on organic pollutants, odors, and toxic gases in the wastewater, and avoids the situation where the wastewater continuously flows to the fixed area of ​​the trapezoidal filter layers 61, causing the adsorption and treatment capacity of the trapezoidal filter layers 61 in a local area to be overloaded.

[0075] The activated water pump 552 draws out the wastewater from the treatment shell 1 after it has undergone fixed impurity filtration and adsorption treatment by several trapezoidal filter layers 61. The wastewater is then transported to the multi-stage treatment tank 62 through the delivery pipe 556. After flowing into the multi-stage treatment tank 62, the wastewater flows from top to bottom through several inclined filter layers 63. The inclined filter layers 63 also treat the wastewater. Finally, the wastewater after multi-stage treatment flows out through the flange pipe 64. The installation method of the inclined filter layers 63 in the multi-stage treatment tank 62 allows the wastewater to continue flowing from top to bottom within the inclined filter layers 63 when it first flows into them, due to gravity and the fluidity of the wastewater. This not only increases the contact area between the wastewater and the inclined filter layers 63, thereby increasing the wastewater treatment effect of the inclined filter layers 63, but also prolongs the contact time between the wastewater and the inclined filter layers 63, thereby further improving the wastewater treatment effect of the inclined filter layers 63.

[0076] This invention employs a primary treatment mechanism 4 and a subsequent treatment mechanism 5 to physically filter solid impurities in wastewater generated during battery production, using multi-stage screening. Then, a multi-stage treatment mechanism 6 further treats the filtered wastewater, removing organic matter, odors, and toxic gases through a combination of chemical and biological methods. This synergistic use of physical, chemical, and biological treatment methods achieves multi-stage treatment of wastewater generated during battery production, thereby improving the overall efficiency of the device in treating wastewater.
