Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to an integrated SY-type submerged ultrafiltration membrane water purification device. Background Technology

[0002] Ultrafiltration membrane technology, with its advantages of high-efficiency physical separation capabilities (retention of suspended solids, colloids, bacteria, and macromolecular organic matter), low operating pressure, and no need for chemical additives, has become a core technology in wastewater treatment and reuse. Submerged ultrafiltration systems, due to their small footprint, high process integration, and strong adaptability, are widely used in the advanced treatment of municipal wastewater, industrial wastewater, and drinking water. The core principle is to directly immerse the membrane module (usually a curtain membrane) in the membrane tank to be treated. Negative pressure is used to force water through the membrane pores to become product water (purified water), while pollutants are retained on the membrane surface or within the membrane tank. However, existing technologies have the following problems: First, poor height adaptability: membrane curtain positioning frames are mostly of fixed height, unable to accommodate different specifications of membrane curtains. Replacing membrane curtains requires custom-made brackets, increasing costs. Second, the fixed position of the aeration pipes makes it impossible to adjust the distance according to the height of the bottom of the membrane curtain. Excessive distance leads to uneven aeration and exacerbates membrane surface fouling. Third, high aeration energy consumption: traditional aeration pipes use continuous aeration throughout the entire process, making zoned control impossible. In actual operation, the gas demand in some areas is low, resulting in energy waste. Fourth, the structural stability is insufficient: the weight of the membrane curtain increases with operation, and the water pipes lack effective support and are prone to deformation; the membrane curtain is also prone to loosening, leading to structural failure. Fifth, the pipeline system has too few functions and is inefficient: most pipeline systems of similar equipment on the market only have the functions of water inlet, water production, and sewage discharge, and cannot take on other functions, resulting in insufficient integration.

[0003] While an ultrafiltration device is proposed in patent document CN202010061674.8, entitled "A Curtain Membrane Module for Water Purification," which solves the structural stability problem, other issues still exist. To address these shortcomings, a new water purification device is urgently needed. Utility Model Content

[0017] Compared with the prior art, the present invention provides a graphite pressing molding mold opening device, which has the following beneficial effects.

[0018] 1. Rapid installation and high integration: The standardized quick-installation frame, consisting of four membrane curtain positioning components and four longitudinal reinforcing ribs, combined with dedicated water collection pipe supports, aeration pipe supports, L-shaped clamps, and U-shaped clamps, enables rapid, accurate positioning and reliable connection of the membrane curtain, water pipes, water collection pipes, and aeration distribution pipes, significantly simplifying on-site installation steps and improving assembly efficiency.

[0019] 2. Flexible height adjustment: The positioning components of the membrane curtain adopt a sliding connection between the upper sleeve and the lower slide rod. With the axially evenly distributed adjustment through holes and pins, the overall height of the mold frame can be adjusted within a certain range. The operation is simple and quick, and the locking is firm. It effectively solves the compatibility problem of membrane curtains of different heights and enhances the versatility and adaptability of the equipment.

[0020] 3. Adjustable aeration height and uniformity: The lifting mechanism at the bottom of the aeration distribution pipe drives the screw to rotate by turning the handle, which in turn drives the upper and lower platforms connected by the X hinge to rise and fall. This allows for easy adjustment of the distance between the aeration distribution pipe and the bottom of the membrane curtain, ensuring optimal aeration effect (bubble size and scouring intensity) and uniformity, adapting to different working conditions or membrane module installation status.

[0021] 4. Controllable Aeration Mode, Energy-Saving and Highly Efficient: The aeration distribution pipe adopts a design of a main aeration pipe paired with aeration branch pipe groups with independent control valves, and control valves are also installed between the branch pipe groups on the main pipe. This allows the system to achieve "full-open" powerful aeration, as well as "segmented and grouped" aeration as needed. The latter allows for precise control of the aeration volume by area and as needed, completing a refined aeration cycle within a certain aeration period. While ensuring aeration quality (such as preventing membrane fouling), it significantly reduces the energy consumption of the aeration blower, achieving the goal of energy saving and consumption reduction.

[0022] 5. Enhanced structural stability: L-shaped clamps and U-shaped through holes work together to fix the water pipe (3), preventing deformation under pressure. Horizontal reinforcing ribs are vertically connected to longitudinal reinforcing ribs to improve the bending strength of the membrane curtain.

[0023] 6. High level of pipeline integration: Multiple pipelines are installed, providing functions such as water inlet, aeration, product water, sewage discharge, backwashing, overflow, and venting. The aeration pipeline centrally connects the membrane tank aeration inlet to the main aeration pipe of each water collector, while the product water pipeline centrally connects the membrane tank product water outlet to the water collection outlet of each water collector. The backwash inlet and product water outlet share a single pipeline; this design reduces the number of interfaces and improves system sealing, integrity, and ease of maintenance.

[0024] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

Detailed Implementation

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0043] Reference Figure 1-17 An integrated SY-type submerged ultrafiltration membrane water purification device includes a membrane tank 10, quick-install ultrafiltration membrane water collectors 20, and a piping system connecting the two. The membrane tank 10 is characterized by having a membrane tank cover 1001 at the top and a membrane tank support 1002 at the bottom. Several ultrafiltration membrane water collectors 20 are evenly distributed longitudinally inside the membrane tank 10; this embodiment uses four, but the specific number and arrangement can be selected according to needs. Adjacent quick-install ultrafiltration membrane water collectors 20 are connected together with bolts via connectors 107 to ensure structural stability. The piping system includes an aeration pipe 12 and a product water pipe 13.

[0044] The quick-assembly ultrafiltration membrane water collector 20 includes a quick-assembly frame, an aeration distribution pipe 8, and a water collection pipe 6. The quick-assembly frame is characterized by consisting of four membrane curtain positioning members 1 symmetrically arranged vertically and horizontally, and four longitudinal reinforcing ribs 105 symmetrically fixed to the left and right sides of the two membrane curtain positioning members 1 at the upper and lower ends. The longitudinal reinforcing ribs 105 connect the two membrane curtain positioning members 1, ensuring structural strength and stability. The water collection pipe 6 is fixed to the upper part of the two membrane curtain positioning members 1 via two symmetrically arranged water collection pipe supports 5. The aeration distribution pipe 8 is fixed to the bottom of the two membrane curtain positioning members 1 at the lower end via several aeration pipe supports 4. The aeration pipe supports 4 serve two purposes: firstly, to fix the device to the membrane tank using their bottom (the connection method is not specifically shown in this embodiment and can be selected according to needs); secondly, to connect the two membrane curtain positioning members 1 at the lower end, supporting the entire device and ensuring its structural strength. The basic function of the aeration distribution pipe is to guide air to the aeration membrane in the aeration pipe through a blower. The air forms micropores on the membrane, realizing fine aeration of the water and promoting effective contact between oxygen in the air and water. It provides oxygen while biological oxidation continuously consumes oxygen, maintaining a certain dissolved oxygen concentration in the water. In addition to supplying oxygen, it also generates sufficient stirring and mixing in the aeration tank area, promoting water circulation and ensuring that activated sludge and wastewater are fully contacted and mixed. It maintains a certain movement speed of the mixed liquor, keeping the activated sludge in a suspended state in the mixed liquor.

[0045] The membrane curtain positioning component 1 is a rectangular plate with several U-shaped through holes evenly distributed on its upper surface. Two U-shaped through holes on the same side are connected to a water pipe 3, and two water pipes 3 on the same plane are connected to a membrane curtain 2. The water collection pipe 6 has several water collection pipe inlets 602 evenly distributed on one side of its axis. The positions of the water collection pipe inlets 602 match the positions of the U-shaped through holes, and the water collection pipe inlets 602 are connected to the water pipes 3 within the U-shaped through holes. The water collection pipe 6 has a water collection pipe outlet 601 on the other side of its axis. The membrane curtain 2 has an ultrafiltration membrane in its middle. The upper and lower ends of the ultrafiltration membrane are symmetrically connected and connected to two pipes. The left and right ends of each pipe are connected to two corresponding water pipes 3. Membrane curtain 2 is used to treat raw water, i.e., dirty water containing pollutants, converting it into purified water. Several sets of membrane curtains 2 provide a large effective working area, and membrane curtain 2 and water pipe 3 form a complete passage. To ensure the airtightness and reasonable placement of the structure, elbows such as right-angle elbows and tee elbows can be used for connection. Using ultrafiltration membrane as the filtration medium, under a certain pressure, when raw water flows through the membrane surface, the numerous tiny micropores densely distributed on the ultrafiltration membrane surface only allow water and small molecules to pass through, becoming the permeate. Substances in the raw water with a volume larger than the micropore diameter of the membrane surface are retained on the inlet side of the membrane, becoming the concentrate, i.e., purified water. Thus, the purpose of purifying, separating, and concentrating the raw water is achieved. The purified water flows along the ultrafiltration membrane into the pipes above and below it, then along the water pipe 3 through the water inlet 602 into the water collection pipe 6 for storage. When needed, it is discharged through the water outlet 601 of the water collection pipe. Figure 17 As shown.

[0046] The upper membrane curtain positioning component 1 has two upper sleeves 101 symmetrically fixed on the lower surfaces of its left and right ends. The lower membrane curtain positioning component 1 has two lower sliding rods 102 symmetrically fixed on the upper surfaces of each of its left and right ends. The upper sleeves 101 and lower sliding rods 102 are matched and form a sliding structure. The upper sleeves 101 have several adjustment through holes evenly distributed along their axial direction, and the lower sliding rods 102 have several identical adjustment through holes evenly distributed along their axial direction. Because the height of the membrane curtain 2 is not fixed, commonly found in the market at 1.5m and 1.8m, different membrane curtain 2 heights require the installation mold frame to have a certain degree of adaptability for adjustment. In this invention, the lower sliding rods 102 are inserted into the upper sleeves 101 to form a sliding structure. After adjusting to the appropriate height for the membrane curtain, pins are inserted into the adjustment through holes between the two to lock the height. This height adjustment structure not only allows for quick adjustment and simple operation, but also adapts to membrane curtains 2 of different heights. Its manufacturing and installation are also simple and convenient, and the cost is low.

[0047] An L-shaped clamp 106 is bolted to the outside of the U-shaped through hole of the membrane curtain positioning component 1. The L-shaped clamp 106 has an arc segment that matches the arc segment of the U-shaped through hole, and the arc segments of both clamp together to hold the water pipe 3. Two transverse reinforcing ribs 104 are symmetrically provided at the bottom of the upper and lower pipes of the membrane curtain 2. The two transverse reinforcing ribs 104 are simultaneously and vertically fixed to two longitudinal reinforcing ribs 105 at the same end.

[0048] The lower surface of the water collection pipe bracket 5 is fixed to the upper surface of the two membrane curtain positioning parts 1 at the upper end. The upper surface of the water collection pipe bracket 5 is provided with a T-shaped boss. Two mounting through holes are symmetrically opened on the upper surface of the T-shaped boss. A U-shaped clamp 7 is threaded into the mounting through hole. The water collection pipe 6 is installed on the upper surface of the T-shaped boss and its end is clamped by the U-shaped clamp 7 to secure the water collection pipe 6.

[0049] The aeration distribution pipe 8 includes an aeration main pipe 801 and several aeration branch pipe groups evenly arranged on the aeration main pipe 801. Each aeration branch pipe group includes two symmetrical aeration branch pipes 802. The axis of each aeration branch pipe 802 is perpendicular to the axis of the aeration main pipe 801. A control valve 803 is provided at the connection between each aeration branch pipe 802 and the aeration main pipe 801. A control valve 803 is also provided between the two groups of aeration branch pipes on the aeration main pipe 801. This invention offers two aeration modes: a fully open mode, where the dedicated control system opens all control valves 803, allowing all aeration branch pipes 802 and the main aeration pipe 801 to aerate simultaneously; and a segmented and grouped mode, where when air enters the main aeration pipe, the control valves 803 between the two groups of aeration branch pipes on the main aeration pipe 801 open sequentially, and the control valves 803 of each aeration branch pipe 802 open as needed, enabling segmented and grouped microporous aeration circulation. A complete cycle is circulated before one aeration segment ends to ensure aeration quality, significantly saving aeration volume and reducing the installed power of the aeration blower while saving energy. Furthermore, the gas generated by the aeration branch pipes can vibrate the ultrafiltration membrane, improving cleaning quality during cleaning.

[0050] The upper surface of the aeration pipe support 4 is fixed to the lower surface of the two lower membrane curtain positioning parts 1. The bottom of the aeration distribution pipe 8 is equipped with several lifting mechanisms 9. Each lifting mechanism 9 includes two symmetrically arranged platforms 901. The lower platform of the lifting mechanism 9 is fixed to the aeration pipe support 4. The two platforms 901 are connected by four sets of X-hinges 902 arranged symmetrically in the front and back. The lower part of the upper X-hinge 902 is rotatably connected to the upper part of the lower X-hinge 902. The four sets of X-hinges 902 form four connection points. Two connecting rods are fixed between the four connection points. A nut 904 is connected to the middle of each connecting rod. The nuts 904 of the several lifting mechanisms 9 are threaded together to a matching lead screw 903. One end of the lead screw 903 has a rotating handle 905. In actual installation, the aeration pipes are mostly fixed to the bottom of the membrane tank, but the bottom height of the membrane curtain 2 varies. If the bottom of the membrane curtain 2 is too far from the aeration distribution pipe, the aeration quality will be affected. This invention uses the forward and reverse rotation of the handle 905 to rotate the lead screw 903 in both directions. By changing the height of the X hinge 902 through the lead screw nut structure, the vertical distance between the two platforms 901 is changed, thereby adjusting the distance between the aeration distribution pipe 8 and the membrane curtain 2 to ensure aeration quality.

[0051] The membrane tank 10 has vertically arranged aeration ports 120 on its lower surface. Each aeration port 120 is equipped with a control valve 803. One end of the aeration pipe 12 is connected to the main aeration pipe 801 of several aeration distribution pipes 8, and the other end is connected to the aeration port 120. The aeration port is connected to an external aeration device, which pumps air into the aeration port 120. The control valve 803 on the aeration port 120 is opened, and the gas flows along the aeration pipe 12 into the main aeration pipe 801 of the four aeration distribution pipes 8. Aeration is then selected as needed.

[0052] The membrane tank 10 has a drain outlet 14, a raw water inlet 11, and an overflow pipe 16 vertically arranged on its lower surface. All three are connected to the interior of the membrane tank 10, and each is equipped with a control valve 803. The raw water inlet 11 is used to inject raw water mixed with treatment agents into the membrane tank for the quick-install ultrafiltration membrane water collector 20 to treat it into purified water. The drain outlet 14 is used to discharge other impurities besides the purified water after treatment.

[0053] The membrane tank 10 has a vertically arranged water outlet 130 on its lower surface, and a control valve 803 is provided on it. One end of the water outlet 13 is connected to the water outlet 130, and the other end is connected to several water collection pipe outlets 601. The water outlet 130 is vertically connected to a backwash port 15, and the backwash port 15 is provided with a control valve 803. After the quick-install ultrafiltration membrane water collector 20 finishes treating the purified water, it is stored in four water collection pipes 6 and discharged into the water outlet 601 of the water collection pipes. Finally, the control valve 803 on the water outlet 130 is opened, and the purified water is discharged from the water outlet 130. After the membrane tank 10 has been working for a long time, a large amount of impurities will accumulate inside it and on the ultrafiltration membrane of the quick-install ultrafiltration membrane collector 20. In order to ensure the normal operation of both, cleaning is required. The backwash port 15 is used to clean the entire interior of the membrane tank 10 and the quick-install ultrafiltration membrane collector 20. The backwashing agent in the dosing pump and the clean water in the backwash water tank are mixed by the backwashing pump and injected into the interior of the membrane tank 10 through the backwash port 15 (note that the control valve 803 on it should be opened) for cleaning. After cleaning, the sewage is discharged from the drain port 14. During the cleaning process, the aeration distribution pipe can also be used to assist in cleaning.

[0054] A level transmitter 19 is located at the bottom right side of the membrane tank 10, and a vacuum detection box 17 and an exhaust pipe 18 are located at the top left side of the membrane tank cover 1001. The level transmitter 19 is used to detect the liquid level in the membrane tank. When the liquid level exceeds a threshold, the control valve 803 on the overflow pipe 16 is opened to discharge the excess liquid through the overflow pipe 16. Because this invention requires the air pressure inside the membrane tank 10 to be within a certain threshold during operation, when the internal pressure of the membrane tank 10 is too high, the vacuum detection box 17 will detect this and open the exhaust pipe 18 to release air and ensure normal air pressure.

[0055] Compared to similar products on the market, this utility model features a highly integrated pipeline system with multiple functions, including water inlet, aeration, water production, sewage discharge, backwashing, overflow, and venting. The aeration pipeline centrally connects the membrane tank aeration port to the main aeration pipe of each water collector, while the water production pipeline centrally connects the membrane tank water production port to the water collection outlet of each water collector. The design of sharing a single pipeline between the backwash port and the water production port reduces the number of interfaces and improves system sealing, overall integrity, and ease of maintenance.

[0056] The raw water inlet 11, aeration inlet 120, product water inlet 130, sewage outlet 14, backwash inlet 15, overflow pipe 16, exhaust pipe 18, aeration pipeline 12, and product water pipeline 13 shown in this embodiment represent only one configuration method and are not the only one.

[0057] Working process: After connecting all the components or structures of this utility model, welding or other connection methods can be used as needed. During installation, according to the actual height of the membrane curtain 2, insert the sliding rod 102 of this utility model into the upper sleeve 101 and adjust it to the appropriate height of the membrane curtain. Align the adjustment through hole between the two and insert the pin to lock the height. Adjust the distance between the aeration distribution pipe 8 and the membrane curtain 2 by rotating the handle 905 in both directions. At the same time, ensure that the connection between the membrane curtain 2, water pipe 3 and water collection pipe is intact. When installing the U-shaped clamp 7, L-shaped clamp 106 and transverse reinforcing rib 104, be careful not to interfere with other components. The entire utility model is then hoisted into the membrane tank for operation. Raw water mixed with treatment agents is injected into the membrane tank through the raw water inlet 11, where it is treated by the quick-install ultrafiltration membrane water collector 20 to become purified water. The blower is turned on to pump air from the aeration inlet 120 through the aeration pipe 12 into the aeration main pipe 801, and a full-scale aeration or segmented / grouped aeration is performed as needed using a dedicated control system. Then, the raw water in the membrane tank uses the ultrafiltration membrane as the filtration medium. Under a certain pressure, when the raw water flows over the membrane surface, the numerous tiny micropores densely distributed on the ultrafiltration membrane surface only allow water and small molecules to pass through, thus becoming purified water. The raw water is permeated with liquid, while substances with a volume larger than the micropore size of the membrane surface are trapped on the feed side of the membrane, becoming concentrated liquid, i.e., purified water. The aeration and gas distribution pipe 8 accelerates this process, thus achieving the purpose of purifying, separating, and concentrating the raw water. The purified water enters the pipes above and below the ultrafiltration membrane, then enters the water collection pipe 6 through the water inlet 602 along the water pipe 3 for storage, and is discharged into the product water pipeline through the water collection pipe outlet 601. Finally, it is discharged into the external clear water tank through the product water outlet 130 and finally enters the water supply network. After treatment, other impurities besides purified water are discharged through the sewage outlet 14. To clean the large amount of impurities accumulated inside the membrane tank 10 and on the ultrafiltration membrane of the quick-install ultrafiltration membrane collector 20, the backwashing agent in the dosing pump and the clean water in the backwash tank are mixed by the backwashing pump and injected into the membrane tank 10 through the backwash port 15 for cleaning. After cleaning, the wastewater is discharged from the drain port 14. During the cleaning process, the aeration distribution pipe can also be used to assist in cleaning. Throughout the operation, the vacuum detection box 17 and the level transmitter 19 will constantly monitor the air pressure and liquid level inside the membrane tank 10. If the threshold is exceeded, the overflow pipe 16 will be opened for overflow and the vent pipe 18 will be opened for venting.
