Description

Technical Field

[0001] This invention belongs to the field of wastewater purification and treatment technology, and more specifically, relates to a wastewater purification device. Background Technology

[0002] In today's environment of increasing environmental awareness, wastewater purification has become a crucial link in industrial production and daily life. Among them, hollow fiber membrane wastewater purification devices have been widely used in the field of wastewater purification due to their high-efficiency filtration performance. This device uses hollow fiber membrane tubes to filter and separate impurities and pollutants in wastewater, thereby achieving wastewater purification. However, some existing hollow fiber membrane wastewater purification devices have revealed numerous problems in actual use. First, how to better achieve wastewater treatment through structural design of the hollow fiber membrane tubes is a problem that needs to be addressed. Second, after long-term use, a large amount of impurities and dirt will adhere to the surface of the hollow fiber membrane tubes, seriously affecting the filtration efficiency and purification effect. However, due to the lack of an effective retrieval structure in current technology, moving several hollow fiber membrane tubes from inside the purification tank to the outside for cleaning or replacement is extremely difficult and often requires a lot of manpower, material resources, and time. Third, if the hollow fiber membrane tubes cannot be disassembled, cleaned, or replaced in a timely and convenient manner, it will not only lead to a continuous decline in the purification capacity of the purification device, but may also cause more serious problems such as membrane tube blockage and damage, thereby shortening the service life of the entire purification device and increasing equipment maintenance and replacement costs.

This technology discloses a purification and storage device for wastewater recycling, comprising a pH adjustment tank, a coagulation tank, a flocculation tank, and an electrolysis tank. The coagulation tank is located at the bottom of the pH adjustment tank, the flocculation tank is located at the bottom of the coagulation tank, and the electrolysis tank is located at the bottom of the flocculation tank. The outer wall of the electrolysis tank is connected to a storage tank through a return pipe, and a booster pump is installed on the return pipe. A wastewater inlet is provided on one side of the top of the pH adjustment tank, and a metering pump is connected to the other side of the top through an alkali pipe. A discharge plate is provided at the bottom of the coagulation tank, with a motor sealing box at the center of the discharge plate and a discharge valve on the side. This invention improves the purification efficiency and quality of wastewater generated during PCB manufacturing by subjecting it to a series of processes: removal of acidic impurities with alkaline solution, impurity removal via activated carbon filter, coagulation with coagulant, flocculation with flocculant, filtration via fiber membrane filter, electrolysis, and reverse osmosis. The purified wastewater is then stored in a storage tank. This technology does not address the technical problems or solutions described in this application. Summary of the Invention

[0031] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of the present invention, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0032] As attached Figure 1 - Appendix Figure 11As shown, this invention is a wastewater purification device. A cylinder cover 4 is provided on the top surface of the purification cylinder 2. A drain pipe 7, connected to the inner cavity below the mounting cover 11, is fixed to the bottom end of the purification cylinder 2. A movable cover 9 and the mounting cover 11 are slidably connected to the inner circumferential wall of the purification cylinder 2. The movable cover 9 is located above the mounting cover 11 and is fixed to the bottom surface of the cylinder cover 4 by several fixing posts 10. The mounting cover 11 is fixed to the bottom surface of the movable cover 9 by several connecting posts 12. Several through-type movable covers are fixed on the movable cover 9. The moving cover 9 is connected to the upper fixed pipe 14 above its inner cavity. The bottom surface of the mounting cover 11 is fixed with lower fixed pipes 15 corresponding to the positions of several upper fixed pipes 14. Hollow fiber membrane tubes 16 for filtration are slidably inserted between the upper fixed pipes 14 and their corresponding lower fixed pipes 15. Each lower fixed pipe 15 has several water outlet holes 21 communicating with the inner cavity above the mounting cover 11. The bottom surface of the mounting cover 11 is fixed with several water outlet pipes 17 communicating with the inner cavity above the mounting cover. The wastewater purification device also includes a base plate 1. The purification cylinder 2 is fixedly connected to the base plate 1 via several support columns 3. An inlet funnel 6 communicating with the inner cavity of the cylinder cover 4 is fixed to the top surface of the cylinder cover 4. Solenoid valves 8 are installed on the outer walls of both the inlet funnel 6 and the outlet pipe 7. The wastewater purification device further includes a retrieval mechanism 5, which is used to raise and lower the movable cover 9 and the mounting cover 11. The retrieval mechanism 5 includes an L-shaped vertical plate 51 fixed to the top surface of the base plate 1, a rotating column 52 rotatably connected to the horizontal end of the vertical plate 51, a rotating roller 53 rotatably connected to the top surface of the base plate 1, a screw 54 coaxially fixed between the rotating roller 53 and the rotating column 52, a connecting plate 55 threadedly connected to the screw 54, a rotating rod 57 coaxially fixed to the top surface of the rotating column 52, and a motor 510 installed on the top surface of the horizontal end of the vertical plate 51 to drive the rotating rod 57 to rotate. The connecting plate 55 is slidably connected to the left side surface of the vertical end of the vertical plate 51, and the outer end of the connecting plate 55 is fixed to the cylinder cover 4. The above structure addresses the shortcomings of the prior art and proposes an improved technical solution. The structure is designed with a base plate 1, a purification cylinder 2, several support columns 3, a cylinder cover 4, a drain pipe 7, a movable cover 9, several fixed columns 10, an installation cover 11, several connecting columns 12, several upper fixed pipes 14, several lower fixed pipes 15, and several hollow fiber membrane tubes 16. This allows for convenient and reliable wastewater purification. The retrieval mechanism 5 allows for easy and effortless movement of the movable cover 9, fixed columns 10, installation cover 11, connecting columns 12, upper fixed pipes 14, lower fixed pipes 15, and hollow fiber membrane tubes 16 outside the purification cylinder 2. Furthermore, the cooperation of the connecting columns 12 and the installation cover 11 allows for quick separation of the installation cover 11 from the movable cover 9, facilitating the disassembly of the hollow fiber membrane tubes 16 for cleaning or replacement. This ensures the entire device can perform wastewater treatment normally and efficiently.The wastewater purification device of the present invention has a simple structure, ensuring that the hollow fiber membrane tube can treat wastewater conveniently and reliably, and enabling quick and labor-saving retrieval of the hollow fiber membrane tube. At the same time, it facilitates and facilitates the replacement of the hollow fiber membrane tube, reducing the labor intensity of operation, improving the work efficiency, and reducing equipment maintenance costs.

[0033] The salvage mechanism 5 also includes two pulleys 58 located above the horizontal end of the upright plate 51 and connected by a belt 59, and a rotating shaft 511 coaxially connected to the output shaft of the motor 510. The two pulleys 58 are coaxially fixed on the outer circumference of the rotating shaft 511 and the rotating rod 57, respectively. This structure, by smoothly driving the rotating rod 57 to rotate, can indirectly drive the screw 54 to rotate. The screw 54 rotates in different directions, causing the connecting plate 55 to rise and fall linearly.

[0034] The inner circumferential wall of the purification cylinder 2 is provided with several sliding grooves 22. The outer circumferential wall of the movable cover 9 and the outer circumferential wall of the mounting cover 11 are both fixed with sliding strips 18 corresponding to the number and position of the sliding grooves 22. Each sliding strip 18 is slidably connected within its corresponding sliding groove 22. This structure, with the sliding strips and grooves working together, ensures that the movable cover 9 and the mounting cover 11 are reliably locked and limited within the purification cylinder 2, ensuring that they can only move up and down along the purification cylinder 2 and cannot rotate.

[0035] The purification cylinder 2 has a downward-extending conical structure at its bottom. A drain pipe 7 is connected to the lowest point of the bottom of the purification cylinder 2, and a solenoid valve 8 is installed on the drain pipe 7. The angle between the bottom of the purification cylinder 2 and the horizontal line is between 17° and 29°. This conical structure ensures that the purified wastewater can be smoothly discharged from the purification cylinder 2. Discharge is achieved by opening the solenoid valve.

[0036] The outer circumferential wall of the movable cover 9 is fitted to the inner circumferential wall of the purification cylinder 2 via a sealing strip, and the outer circumferential wall of the mounting cover 11 is fitted to the inner circumferential wall of the purification cylinder 2 via a sealing strip. This structure ensures that wastewater will not flow through the inner circumferential walls of the movable cover and purification cylinder 2. Wastewater can only enter the hollow fiber membrane tube 16 from the upper fixed pipe 14 and then flow out from the outlet holes of the outer ring of the hollow fiber membrane tube 16 and the lower fixed pipe 15. The upper fixed pipe 14 protrudes from the lower end of the movable cover 9 and is slidably inserted into the interior of the hollow fiber membrane tube 16 on the same side. The portion of the hollow fiber membrane tube 16 near its bottom is slidably inserted into the corresponding lower fixed pipe 15. This structure ensures reliable positioning of the hollow fiber membrane tube 16, forming a reliable wastewater purification channel and guaranteeing the wastewater purification effect.

[0037] The vertical plate 51 has a guide groove on its left side surface, and the connecting plate 55 has a guide block 56 fixed on its right side surface, which is slidably connected to the guide groove on the left side surface of the vertical plate 51. This structure guides the movement of the connecting plate 55, and indirectly guides the movement of the moving cover 9, several fixed columns 10, the mounting cover 11, several connecting columns 12, several upper fixed tubes 14, several lower fixed tubes 15, and several hollow fiber membrane tubes 16, ensuring the cylinder cover rises and falls vertically, and thus the aforementioned components also rise and fall vertically.

[0038] Two symmetrical handles 19 are fixed to the bottom surface of the mounting cover 11. The upper end of the connecting post 12 is fixed to the bottom surface of the movable cover 9. The bottom end of the connecting post 12 is provided with a threaded hole. The bottom surface of the mounting cover 11 is provided with several through holes that correspond to the positions and sizes of the threaded holes on the bottom surface of the connecting post 12 on the same side. Each screw passes through the through hole and is screwed into the threaded hole of the corresponding connecting post. With the above structure, the screws and connecting posts are fixed to connect the mounting cover and the connecting posts. When disassembly is required, the screws can be removed, and the mounting cover 11 and the movable cover 9 can be separated.

[0039] The movable cover 9 has several bolts 13 located below it. The bolts 13 pass through the through holes on the mounting cover 11 and are screwed into the corresponding threaded holes on the movable cover 9. With this structure, the bolts can reliably connect the mounting cover and the movable cover, and disassembly is also convenient and quick.

[0040] The working process and principle of the wastewater purification device described in this invention are as follows:

[0041] When waste liquid purification is required, the solenoid valve 8 on the outer wall of the inlet funnel 6 is first opened by the external PLC. Then, an appropriate amount of waste liquid is added evenly into the purification cylinder 2 through the inlet funnel 6. The waste liquid enters the inner cavity above the moving cover inside the purification cylinder 2 through the inlet funnel 6. The waste liquid entering the purification cylinder 2 then enters several hollow fiber membrane tubes 16 through several upper fixed tubes 14. The waste liquid entering the hollow fiber membrane tubes 16 can be purified by the hollow fiber membrane tubes 16. A portion of the purified wastewater flows directly out of the hollow fiber membrane tubes 16 and into the cavity above the mounting cover 11, while the remaining purified wastewater flows out from several lower... Several outlet holes 22 on the outer wall of the fixed pipe 15 lead into the inner cavity above the mounting cover 11. The purified wastewater entering the inner cavity above the mounting cover 11 then flows through several outlet pipes 17 through the mounting cover into the inner cavity below the mounting cover, where it accumulates inside the purification cylinder 2 near the bottom. After a period of purification, the external collection box is placed on the top surface of the base plate 1, corresponding to the position of the drain pipe 7. Then, the external PLC activates the solenoid valve 8 on the outer wall of the drain pipe 7 to open, thereby discharging the purified wastewater inside the purification cylinder 2. Afterward, the external PLC activates the solenoid valve 8 on the outer wall of the drain pipe 7 to close, allowing for the next round of wastewater purification. In this way, wastewater purification is achieved efficiently and reliably.

[0042] When it is necessary to disassemble several hollow fiber membrane tubes 16, the motor 510 is first started via an external PLC. The output shaft of the motor 510 rotates, driving the rotating shaft 511 coaxially connected to it to rotate. The rotation of the rotating shaft 511 drives the pulley 58 fixed on the same side coaxially to rotate. The rotation of this pulley 58 drives another pulley 58 connected to it via a belt 59 to rotate. The rotation of this other pulley 58 drives the rotating rod 57 fixed coaxially to rotate. The rotation of the rotating rod 57 drives the rotating column 52 fixed coaxially to rotate. The rotation of the rotating column 52 drives the screw 54 fixed coaxially to rotate. The rotation of the screw 54 drives the screw threaded to rotate. The connecting plate 55 moves upward, guided by the guide block 56 and the guide groove on the left side of the vertical plate 51. This movement of the connecting plate 55 causes the fixed cylinder cover 4 to move upward. The cylinder cover 4 then indirectly causes the movable cover 9 and the mounting cover 11 to move upward. Both the mounting cover 11 and the movable cover 9 move upward under the guidance of two sliding strips 18 on the same side and two sliding grooves on the inner wall of the purification cylinder 2. This upward movement of the mounting cover 11 and the movable cover 9 indirectly causes several hollow fiber membrane tubes 16 to move upward. When the mounting cover 11 moves to a suitable position above the purification cylinder 2, it... The external PLC shuts off motor 510. Then, one worker holds the mounting cover 11 using two handles 19, while another worker unscrews several bolts 13, completely separating them from the mounting cover 11. The worker holding the mounting cover 11 then pulls it downwards. During this downward movement, several hollow fiber membrane tubes 16 separate from the upper fixing tubes 14. Next, the hollow fiber membrane tubes 16 are pulled out from the lower fixing tubes 15, thus completing the disassembly of the hollow fiber membrane tubes 16. This allows for the removal of several... The hollow fiber membrane tubes 16 can be cleaned, and several hollow fiber membrane tubes 16 can be replaced simultaneously. The cleaned or replaced hollow fiber membrane tubes 16 can be connected to several lower fixing tubes 15, or vice versa. Alternatively, several hollow fiber membrane tubes 16 can be connected to several upper fixing tubes 14. The movable cover 9 can be fixed to the mounting cover 11. Conversely, the movable cover 9, several fixing columns 10, several connecting columns 12, several bolts 13, several upper fixing tubes 14, several lower fixing tubes 15, and several hollow fiber membrane tubes 16 can be moved into the purification cylinder 2 and returned to their original positions. This allows for convenient and labor-saving retrieval, disassembly, and replacement of the hollow fiber membrane tubes 16.

[0043] The wastewater purification device of the present invention has an anti-slip plate 20 fixed to the bottom end of the base plate 1, which is adapted to its shape. The thickness of the anti-slip plate 20 is 2-6cm, preferably 3cm, which can increase the friction between the entire device and the ground, thereby making the entire device more stable during operation. The retrieval mechanism 5 also includes a protective box 512 fixed to the top surface of the horizontal end of the vertical plate 51. The motor 510 is located inside the protective box 512, and the rotating shaft 511 passes through the top surface of the protective box 512, which can protect the motor 510 and extend its service life. The motor 510 and the two solenoid valves 8 are electrically connected to an external PLC through wires, and the motor 510 and the two solenoid valves 8 are electrically connected to an external power supply through wires. The external PLC is also electrically connected to an external power supply through wires. The motor 510, the two solenoid valves 8, and other components in this invention are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. All the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method refers to the above working principle. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

By setting a base plate, a purification cylinder, several support columns, a cylinder cover, a drain pipe, a movable cover, several fixed columns, an installation cover, several connecting columns, several upper fixed pipes, several lower fixed pipes, and several hollow fiber membrane tubes, wastewater purification can be carried out. By setting a retrieval mechanism, the movable cover, several fixed columns, the installation cover, several connecting columns, several upper fixed pipes, several lower fixed pipes, and several hollow fiber membrane tubes can be moved to the outside of the purification cylinder. At the same time, the installation cover and the movable cover can be connected by the cooperation of several connecting columns and the installation cover. Separation facilitates the disassembly of several hollow fiber membrane tubes, enabling them to be removed for cleaning or replacement, ensuring the entire purification device can perform wastewater treatment normally and efficiently; 2. A guide groove is provided on the left side surface of the vertical plate end, and a guide block is fixed on the right side surface of the connecting plate, which is slidably connected to the guide groove on the left side surface of the vertical plate end.
