Description

A wastewater recycling device Technical Field

[0001] This utility model relates to the technical field of production wastewater reuse devices, and in particular to a production wastewater reuse device. Background Technology

[0002] Currently, due to the requirements of the production process, a large amount of copper-containing and acidic wastewater is generated during production. This wastewater includes foil washing water, polishing water, acid mist exhaust condensate, etc. After unified recycling, this wastewater is sent to the water station for concentration treatment via a water supply pump. After multiple concentration and circulation treatments, a high-concentration copper-containing and acidic water is formed. After being circulated again by a cyclone electrolysis device, copper ions in the solution are electrolyzed to form copper tubes. After passing inspection, the copper tubes are added to the system. During normal operation of the production system, the total liquid volume of the system will be lost, and pure water needs to be added manually for adjustment. Adding high copper acid solution can both recycle the production wastewater and reduce the amount of pure water used.

[0003] Existing wastewater reuse devices lack efficient stirring or mixing mechanisms when mixing wastewater with high-cubic acid solutions, resulting in incomplete mixing. This affects subsequent wastewater treatment, potentially leading to incomplete treatment or prolonged treatment time. Furthermore, some devices have complex filter installation structures, requiring complex disassembly tools or numerous operational steps to replace the filters. This not only increases maintenance time costs but may also affect wastewater filtration efficiency due to delayed filter replacement, thereby impacting the overall operational efficiency of the wastewater reuse system.

[0004] Therefore, those skilled in the art have provided a wastewater reuse device to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wastewater reuse device. The stirring mechanism can improve the mixing of wastewater and high copper acid solution, thereby increasing the efficiency of the chemical reaction. When the third rotating shaft rotates, it will drive the brush plate to wash the filter screen. Moreover, the filtration mechanism makes it easier to replace the filter screen.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A wastewater recycling device includes a base, a stirring mechanism on one side of the upper end of the base, a storage tank, a motor fixedly mounted inside the lower end of the storage tank, a first rotating shaft fixedly mounted at the output end of the motor, a second bevel gear fixedly mounted on the outer end of the first rotating shaft near the motor, a second rotating shaft rotatably mounted inside the storage tank near the second bevel gear, a first bevel gear fixedly mounted at the lower end of the second rotating shaft, a third rotating shaft rotatably mounted inside the storage tank near the motor, a third bevel gear fixedly mounted on the side of the third rotating shaft near the motor, and multiple brush plates fixedly mounted on the side of the third rotating shaft away from the motor by bolts.

[0008] A filtration mechanism is provided on the upper end of the base. The filtration mechanism includes a filter box. Multiple fixing blocks are rotatably arranged on the upper end of the filter box. A connecting plate is slidably arranged on the upper end of the filter box. A sliding cover is slidably arranged on the upper end of the connecting plate. Multiple filter screens are slidably arranged inside the connecting plate.

[0009] Furthermore, the first bevel gear is meshed with the third bevel gear, and the third bevel gear is meshed with the second bevel gear.

[0010] Furthermore, the second rotating shaft is rotatably sleeved outside the first rotating shaft, and the upper end of the first rotating shaft is rotatably mounted on the upper end of the storage tank.

[0011] Furthermore, multiple stirring blades are fixedly installed on the outside of the first rotating shaft, and multiple scrapers are fixedly installed on the outside of the second rotating shaft.

[0012] Furthermore, the side of the multiple brush plates away from the third bevel gear is disposed on the side of one of the multiple filter screens near the storage tank, and the exterior of the multiple filter screens is slidably disposed inside the filter box, and a sealing gasket is fixedly disposed at the lower end of the connecting plate.

[0013] Furthermore, the lower end of the sliding cover is disposed on the upper end of multiple filter screens, and the lower ends of multiple fixing blocks are disposed on the upper end of the sliding cover and the connecting plate.

[0014] Furthermore, a liquid supply pump is fixedly installed on the upper end of the base, the input end of the liquid supply pump is fixedly installed on one side of the filter box, a connecting pipe is fixedly installed on the output end of the liquid supply pump, a pressure control valve is installed on the upper end of the connecting pipe, and multiple flow meters are installed on the rear end of the connecting pipe.

[0015] Furthermore, a circulation pipe is fixedly installed at the upper end of the pressure control valve, the output end of the circulation pipe is fixedly installed at the upper end of the storage tank, and multiple collection tanks are installed at the upper end of the base away from the liquid supply pump, with the output end of the connecting pipe installed at the upper end of the multiple collection tanks.

[0016] This utility model has the following beneficial effects:

[0017] 1. The present invention proposes a wastewater recycling device. When the motor is running, it drives the first rotating shaft and the second bevel gear to rotate synchronously. Since the second bevel gear meshes with the third bevel gear, the third bevel gear drives the third rotating shaft to rotate, thereby causing the brush plate to brush the filter screen. Since the first bevel gear meshes with the third bevel gear, the second rotating shaft and its external scraper also rotate synchronously. The stirring blades stir the liquid in the storage tank. Moreover, the stirring blades and the scraper rotate in opposite directions, which allows the wastewater and the high copper acid solution to be mixed, thereby improving the chemical reaction efficiency.

[0018] 2. The wastewater reuse device proposed in this utility model allows for the replacement of individual filter screens by rotating the fixing block to release the restriction on the sliding cover. Then, the sliding cover is slid, releasing the pressure on the filter screen and allowing the individual filter screen to be removed from the filter box. When all the filter screens are removed, the operator releases the restriction on the connecting plate by the fixing block and then pulls the sliding cover upward, causing the connecting plate to move upward synchronously. The upward movement of the connecting plate will cause multiple filter screens inside to move upward synchronously, thereby achieving complete removal of the filter screens. The entire operation is simple and convenient, ensuring that the filter screens always maintain a good filtration effect and guaranteeing the stable operation of wastewater treatment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Referring to Figures 1-3, one embodiment of this utility model is provided:

[0028] A wastewater recycling device includes a base 1. A stirring mechanism 2 is mounted on one side of the upper end of the base 1. The stirring mechanism 2 includes a storage tank 201. A motor 209 is fixedly mounted inside the lower end of the storage tank 201. A first rotating shaft 203 is fixedly mounted at the output end of the motor 209. A second bevel gear 207 is fixedly mounted on the outer end of the first rotating shaft 203 near the motor 209. A second rotating shaft 204 is rotatably mounted inside the storage tank 201 near the second bevel gear 207. A first bevel gear 206 is fixedly mounted at the lower end of the second rotating shaft 204. A third rotating shaft 210 is rotatably mounted inside the storage tank 201 near the motor 209. A third bevel gear 208 is fixedly installed. Multiple brush plates 211 are fixedly installed on the side of the third rotating shaft 210 away from the motor 209 by bolts. The first bevel gear 206 is meshed with the third bevel gear 208. The third bevel gear 208 is meshed with the second bevel gear 207. The second rotating shaft 204 is rotatably sleeved on the outside of the first rotating shaft 203. The upper end of the first rotating shaft 203 is rotatably installed on the upper end of the storage tank 201. Multiple stirring blades 202 are fixedly installed on the outside of the first rotating shaft 203. Multiple scrapers 205 are fixedly installed on the outside of the second rotating shaft 204. The side of the multiple brush plates 211 away from the third bevel gear 208 is set on one of the multiple filter screens 305 near the storage tank 201.

[0029] Specifically, when the motor 209 operates, the first rotating shaft 203 rotates inside the storage tank 201. Simultaneously, the second bevel gear 207, fixed externally to the first rotating shaft 203, also rotates. Since the second bevel gear 207 meshes with the third bevel gear 208, the third bevel gear 208 begins to rotate, thereby driving the connected third rotating shaft 210 to rotate. This causes the brush plate 211 fixed on the third rotating shaft 210 to brush the filter screen 305, effectively preventing clogging and ensuring a smooth filtration process. At the same time, the first bevel gear at the lower end of the second rotating shaft 204... Gear 206 meshes tightly with the third bevel gear 208. Driven by the rotation of the third bevel gear 208, the second rotating shaft 204 also begins to rotate synchronously. At this time, the stirring blades 202 installed on the first rotating shaft 203 will stir the liquid in the storage tank 201. It is worth mentioning that the stirring blades 202 and the scraper 205 on the second rotating shaft 204 rotate in opposite directions. The reverse stirring and scraping effect formed by the two can make the production wastewater and the high copper acid solution poured into the storage tank 201 fully and efficiently mixed, promote the chemical reaction between the solutions, and improve the quality and efficiency of wastewater treatment.

[0030] Referring to Figures 1-5, a filter mechanism 3 is provided on the upper end of the base 1. The filter mechanism 3 includes a filter box 301. Multiple fixing blocks 304 are rotatably provided on the upper end of the filter box 301. A connecting plate 302 is slidably provided on the upper end of the filter box 301. A sliding cover 303 is slidably provided on the upper end of the connecting plate 302. Multiple filter screens 305 are slidably provided inside the connecting plate 302. The multiple filter screens 305 are all slidably provided inside the filter box 301. A sealing gasket 306 is fixedly provided on the lower end of the connecting plate 302. The lower end of the sliding cover 303 is provided on the upper end of the multiple filter screens 305. The lower ends of the multiple fixing blocks 304 are provided on the upper ends of the sliding cover 303 and the connecting plate 302.

[0031] Specifically, the filter box 301 contains multiple layers of filter screens 305, which improves filtration accuracy and effectively intercepts and removes various impurities from wastewater, ensuring wastewater treatment quality. If only a single filter screen 305 needs to be replaced, rotate the fixing block 304 to release its restraining effect on the sliding cover 303. Then, slide the sliding cover 303 to remove it from the connecting plate 302. The sliding of the sliding cover 303 releases the pressure restraining the upper part of the filter screen 305, allowing the single filter screen 305 to be easily removed from the filter box 301. The operation is simple and convenient. However, when all the filter screens 305 in the filter box 301 need to be removed, first release the restraining effect of the fixing block 304 on the connecting plate 302. Next, pull the sliding cover 303 upwards. As the sliding cover 303 moves, it will cause the connecting plate 302 to slide upwards synchronously inside the filter box 301. Since multiple filter screens 305 are installed inside the connecting plate 302, the upward movement of the connecting plate 302 will cause all the filter screens 305 inside it to move upwards together, thereby realizing the operation of removing all the filter screens 305. This allows the operator to clean or replace the filter screens 305 regularly, ensuring the filtration effect of the filter screens 305, extending the service life of the equipment, reducing the operating risk of the equipment, and providing a strong guarantee for the stable operation of the entire wastewater treatment system. The sealing gasket 306 on the filter box 301 can ensure the sealing of the filtration process and prevent wastewater leakage.

[0032] Referring to Figure 1, a liquid supply pump 5 is fixedly installed on the upper end of the base 1. The input end of the liquid supply pump 5 is fixedly installed on one side of the filter box 301. A connecting pipe 6 is fixedly installed on the output end of the liquid supply pump 5. A pressure control valve 4 is installed on the upper end of the connecting pipe 6. Multiple flow meters 7 are installed at the rear end of the connecting pipe 6. A circulation pipe 8 is fixedly installed on the upper end of the pressure control valve 4. The output end of the circulation pipe 8 is fixedly installed on the upper end of the storage tank 201. Multiple collection tanks 9 are installed on the upper end of the base 1 away from the liquid supply pump 5. The output end of the connecting pipe 6 is installed on the upper end of the multiple collection tanks 9.

[0033] Specifically, the production wastewater is first concentrated by a thickener and then enters the storage tank 201. Next, a high-cubic acid solution is poured into the storage tank 201 and mixed with the production wastewater by a stirring mechanism 2. Then, the supply pump 5 is started, quickly drawing the filtered wastewater from the filter box 301 and transporting it stably through a connecting pipe 6. A high-precision flow meter 7 is installed on the connecting pipe 6, which monitors the wastewater flow rate in real time. Using the data from the flow meter 7, operators can precisely control the flow rate and total volume of the recovered solution, ensuring the entire production system maintains stable operation throughout the wastewater treatment and reuse process. Finally, the treated wastewater flows smoothly into the collection tank 9 for centralized storage, facilitating further treatment or reuse.

[0034] When recycling is not performed, the valve is closed, the water flow in the connecting pipe 6 is blocked, and the pressure rises. Once the system detects the pressure increase, the pressure control valve 4 automatically opens, guiding the wastewater to flow back into the storage tank 201 through the circulation pipe 8, forming a self-circulation loop. This self-circulation process can effectively reduce the excessive pressure in the connecting pipe 6 and ensure the safe operation of the pipeline and equipment.

[0035] Working principle: When the motor 209 inside the storage tank 201 is running, its output end will drive the first rotating shaft 203 to rotate, which in turn causes the second bevel gear 207 outside to rotate. Since the second bevel gear 207 meshes with the third bevel gear 208, the third bevel gear 208 drives the third rotating shaft 210 to rotate, so that the brush plate 211 brushes the filter screen 305. At the same time, the first bevel gear 206 at the lower end of the second rotating shaft 204 meshes with the third bevel gear 208, which causes the second rotating shaft 204 to start rotating as well. The stirring blades 202 on the first rotating shaft 203 stir the liquid in the storage tank 201, so that the production wastewater and the high copper acid solution are fully mixed, improving the reaction efficiency. Meanwhile, the scraper 205 on the second rotating shaft 204 will rotate synchronously with the storage tank 201, and the rotation direction of the stirring blades 202 and the scraper 205 is opposite.

[0036] Secondly, when wastewater enters the filter box 301, it will be filtered through multiple layers of filter screens 305. When it is necessary to replace a single filter screen 305, first rotate the fixing block 304 to release it from the limiting position of the sliding cover 303. Then, slide the sliding cover 303 to move it away from the connecting plate 302, thereby releasing the pressure on the filter screen 305. Then, the single filter screen 305 can be taken out from the filter box 301. When it is necessary to completely remove the filter screens 305 inside the filter box 301, release the limiting position of the fixing block 304 on the connecting plate 302. Then, by pulling the sliding cover 303 upward, the connecting plate 302 will slide upward inside the filter box 301. The upward movement of the connecting plate 302 will drive the multiple filter screens 305 inside it to move upward synchronously, so as to completely remove the filter screens 305.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
