Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a dual-membrane method for treating pharmaceutical wastewater. Background Technology

[0002] While existing dual-membrane wastewater treatment devices demonstrate good efficiency and effectiveness, some problems remain in practical applications, particularly regarding the connection between the two membrane modules. This connection is prone to clogging, and once clogging occurs, unclogging is inconvenient, affecting the long-term stable operation of the device and potentially leading to downtime or frequent manual maintenance.

[0003] In dual-membrane treatment, ultrafiltration and nanofiltration membrane systems require piping connections for fluid transport and filtration. These connections typically handle large amounts of sludge, suspended solids, particulate matter, and other impurities. High-concentration pharmaceutical wastewater may contain significant amounts of dissolved substances, suspended particles, and drug residues. These substances easily accumulate at the pipe interfaces, connections, and valves between membrane modules, leading to increasingly severe clogging over time.

[0004] Once a blockage occurs, the equipment needs to be stopped for inspection and unblocking. However, existing unblocking methods usually rely on manual operation or require a long backwashing time, which places high demands on the equipment's maintenance cycle and operating efficiency. Without an effective auxiliary cleaning mechanism during the unblocking process, the equipment may be shut down for too long, affecting the production schedule. Utility Model Content

The first unblocking plate is mounted on one end of the rotating sleeve. The rotating sleeve is symmetrically arranged vertically. The second unblocking plate is mounted on another set of rotating sleeves. When the rotating sleeve is rotated back and forth, the opening wall of the unblocking pipe presses against the rotating sleeve, causing the first unblocking plate to retract.

[0009] The present invention is further configured such that the unblocking auxiliary mechanism includes an outer rotating ring, a linkage ring, a rotating block, a winding rod, and a return spring. The outer rotating ring is rotatably mounted on the outer wall of the unblocking pipe. The linkage ring is symmetrically mounted on the top and bottom ends of the outer rotating ring.

[0030] Please see Figures 1-5 A dual-membrane pharmaceutical wastewater treatment device includes a filter connection mechanism, a dredging and adjustment mechanism, and a dredging auxiliary mechanism. The filter connection mechanism includes an ultrafiltration module 1, a nanofiltration module 2, a connecting pipe 3, and a dredging pipe 4. The connecting pipe 3 is installed on the sides of the ultrafiltration module 1 and the nanofiltration module 2, and two sets of connecting pipes 3 are provided. The two ends of the dredging pipe 4 are connected to the connecting pipes 3 to connect the ultrafiltration module 1 and the nanofiltration module 2. The dredging and adjustment mechanism includes a rotating sleeve 5, a rotary groove 6, a rotary block 7, a rotary spring 8, a first dredging plate 9, and... The second unblocking piece 10, the rotating sleeve 5 is limited and rotatably mounted on the outer wall of the clamping pipe, the rotating push groove 6 is set on the inner wall of the rotating sleeve 5, the rotating push block 7 is rotatably mounted in the rotating push groove 6, the rotating push spring 8 is mounted on one end of the rotating push block 7, and the other end of the rotating push spring 8 contacts and supports the inner wall of the rotating push groove 6. The first unblocking piece 9 is mounted on one end of the rotating push block 7. The rotating push blocks 7 are arranged symmetrically up and down. The second unblocking piece 10 is mounted on another set of rotating push blocks 7. The rotating sleeve 5 is rotated back and forth, and the opening wall of the unblocking pipe 4 is pressed against the rotating push block 7, so that the first unblocking piece 9 is retracted.

[0031] In this embodiment, external wastewater enters the inlet pipe 16 from the wastewater outlet device and then enters the ultrafiltration component 1 for preliminary filtration. The ultrafiltration component 1 can remove large molecular pollutants, thus purifying the wastewater initially. The filtered water flows into the nanofiltration component 2 through the connecting pipe 3. The nanofiltration component 2 further removes small molecular organic matter in the water, improving the water purity. The filtered purified water enters the suction pump 18 through the suction pipe 17. The suction pump 18 transports the filtered purified water to the subsequent treatment device through the external inlet pipe 501 for further treatment or reuse. The rotating sleeve 5 is installed on the outer wall of the clamping pipe, and the rotating push block 7 is located inside the rotating sleeve 5. The rotating push spring 8 supports the rotating push block 7, keeping it in an elastic extended state. When the rotating sleeve 5 reciprocates, the rotating push block 7 moves with the rotation and pushes the first unblocking plate 9 and the second unblocking plate 10. The opening wall of the unblocking pipe 4 contacts the rotating push block 7, causing the first unblocking plate 9 to be squeezed and retracted. Then, under the elastic force of the rotating push spring 8, it pops out again. This process can produce a mechanical unblocking effect on the inside of the connecting pipe 3, effectively preventing dirt accumulation and blockage.

[0032] The unblocking auxiliary mechanism includes an outer rotating ring 11, a linkage ring 12, a rotating block 13, a winding rod 14, and a return spring 15. The outer rotating ring 11 is rotatably mounted on the outer wall of the unblocking pipe 4. The linkage ring 12 is symmetrically mounted on the top and bottom ends of the outer rotating ring 11. The winding rod 14 is fixedly mounted on the outer wall of the unblocking pipe 4. The return spring 15 is fitted onto the winding rod 14. The rotating block 13 is rotatably mounted on the winding rod 14, and one end of the rotating block 13 is connected to the rotating sleeve 5. One end of the return spring 15 is connected to the rotating block 13. The linkage ring 12 slides the rotating block 13 in linkage, causing the top and bottom rotating sleeves 5 to rotate back and forth.

[0033] In this embodiment, the outer rotating ring 11 is installed on the outer wall of the unblocking pipe 4, and the linkage ring 12 is symmetrically installed on the top and bottom of the outer rotating ring 11 to form a stable support structure. When the outer rotating ring 11 rotates, the linkage ring 12 will drive the rotating block 13 to rotate. The rotating block 13 is connected to the rotating sleeve 5. Therefore, the rotation of the outer rotating ring 11 will cause the rotating sleeve 5 to rotate back and forth. Thus, the first unblocking plate 9 and the second unblocking plate 10 will also perform unblocking actions. The winding rod 14 is fixed on the outer wall of the unblocking pipe 4, and a return spring 15 is installed on the winding rod 14. When the rotating block 13 completes one rotation, the return spring 15 will generate elastic force to make the rotating block 13 return to the initial position, ensuring that the unblocking mechanism can perform continuous cyclic work.

[0034] Please see Figures 1-5As a supplementary embodiment of a dual-membrane pharmaceutical wastewater treatment device with a filter connection mechanism, a dredging adjustment mechanism, and a dredging auxiliary mechanism: an ultrafiltration component 1 is provided with an addition pipe 16 at one end, and an external wastewater output device is connected to the addition pipe 16; a suction pipe 17 is installed through the side of the nanofiltration component 2, and a suction pump 18 is installed at one end of the suction pipe 17; an external lead pipe 501 is installed at one end of the suction pump 18, and one end of the external lead pipe 501 is connected to an external subsequent treatment device; a mounting frame 19 is installed at the bottom end of the suction pump 18, and a mounting base 20 is installed at the bottom end of the mounting frame 19; the dredging auxiliary mechanism is provided in pairs, and the bottom rotating block 13 drives the bottom rotating sleeve 5 to rotate, so that the first dredging plate 9 and the second dredging plate 10 dredge inward; a connecting plate 21 is installed at one end of the dredging pipe 4, and the connecting plate 21 is connected to one end of the connecting pipe 3.

[0035] More specifically, wastewater enters the inlet pipe 16 from the external equipment and then enters the ultrafiltration component 1. The ultrafiltration component 1 removes larger impurities, and some of the purified water flows to the nanofiltration component 2 through the connecting pipe 3. The nanofiltration component 2 further purifies the water and removes fine pollutants. The purified water enters the suction pump 18 through the suction pipe 17. The suction pump 18 transports the purified water to the subsequent treatment equipment through the external inlet pipe 501 for further treatment or reuse. After the equipment has been running for a certain period of time, the unblocking mechanism is activated. The rotating sleeve 5 drives the first unblocking plate 9 and the second unblocking plate 10 through the rotating push block 7 to mechanically clean the unblocking pipe 4 and the connecting pipe 3 to prevent dirt accumulation and blockage. The unblocking auxiliary mechanism realizes the automatic reset and continuous unblocking of the rotating sleeve 5 through components such as the outer rotating ring 11, the linkage ring 12, the rotating block 13, and the return spring 15, thereby improving the cleaning efficiency. The equipment runs continuously and the unblocking function is triggered periodically to maintain the filtration efficiency and ensure the stability and high efficiency of the wastewater treatment process.

[0036] In summary, during the use or operation of the overall equipment: when the filtration connection mechanism is in operation, external wastewater enters the addition pipe 16 from the wastewater output device and then enters the ultrafiltration component 1 for preliminary filtration. The ultrafiltration component 1 can remove large molecular pollutants, thus purifying the wastewater. The filtered water flows into the nanofiltration component 2 through the connecting pipe 3. The nanofiltration component 2 further removes small molecular organic matter in the water, improving the water purity. The filtered purified water enters the suction pump 18 through the suction pipe 17. The suction pump 18 transports the filtered purified water to the subsequent treatment device through the external inlet pipe 501 for further treatment or reuse.

[0037] When the adjustment mechanism needs to be activated, the rotating sleeve 5 is installed on the outer wall of the clamping pipe, the rotating push block 7 is located inside the rotating sleeve 5, and the rotating push spring 8 supports the rotating push block 7 to keep it in an elastic extended state. When the rotating sleeve 5 rotates back and forth, the rotating push block 7 moves with the rotation and pushes the first unblocking plate 9 and the second unblocking plate 10. The opening wall of the unblocking pipe 4 contacts the rotating push block 7, causing the first unblocking plate 9 to be squeezed and retracted. Then, under the elastic force of the rotating push spring 8, it pops out again. This process can produce a mechanical unblocking effect on the inside of the connecting pipe 3, effectively preventing the accumulation of dirt and blockage.

[0038] When the auxiliary unblocking mechanism is in operation, the outer rotating ring 11 is installed on the outer wall of the unblocking pipe 4, and the linkage ring 12 is symmetrically installed on the top and bottom of the outer rotating ring 11 to form a stable support structure. When the outer rotating ring 11 rotates, the linkage ring 12 will drive the rotating block 13 to rotate. The rotating block 13 is connected to the rotating sleeve 5. Therefore, the rotation of the outer rotating ring 11 will cause the rotating sleeve 5 to rotate back and forth. Thus, the first unblocking plate 9 and the second unblocking plate 10 will also perform unblocking actions. The winding rod 14 is fixed on the outer wall of the unblocking pipe 4. The winding rod 14 is equipped with a return spring 15. When the rotating block 13 completes one rotation, the return spring 15 will generate elastic force to make the rotating block 13 return to the initial position, ensuring that the unblocking mechanism can perform continuous cyclic work.

[0039] Wastewater enters the inlet pipe 16 from the external equipment and then enters the ultrafiltration component 1. The ultrafiltration component 1 removes larger impurities, and some of the purified water flows to the nanofiltration component 2 through the connecting pipe 3. The nanofiltration component 2 further purifies the water and removes fine pollutants. The purified water enters the suction pump 18 through the suction pipe 17. The suction pump 18 transports the purified water to the subsequent treatment equipment through the external inlet pipe 501 for further treatment or reuse. After the equipment has been running for a certain period of time, the unblocking mechanism is activated. The rotating sleeve 5 drives the first unblocking plate 9 and the second unblocking plate 10 through the rotating push block 7 to mechanically clean the unblocking pipe 4 and the connecting pipe 3 to prevent dirt accumulation and blockage. The unblocking auxiliary mechanism realizes the automatic reset and continuous unblocking of the rotating sleeve 5 through components such as the outer rotating ring 11, the linkage ring 12, the rotating block 13, and the return spring 15, thereby improving the cleaning efficiency. The equipment runs continuously and the unblocking function is triggered periodically to maintain the filtration efficiency and ensure the stability and high efficiency of the wastewater treatment process.
