[0002] At present, domestic water treatment technologies are usually sedimentation biochemical treatment or chemical treatment. However, traditional treatment methods have limitations in filtering difficult-to-degrade organic matter and trace pollutants.

Ultrafiltration membrane, as an effective tool for sewage treatment, has significantly improved water purification efficiency and water quality, and has also been widely popularized around the world.

[0003] In a membrane stack reactor, the filter membrane assembly is fixed by a mounting seat and placed in the water body. The filter membrane assembly is exposed in the water body, and multiple filter membranes of the same length are placed upright. The mounting seat has a good fixing effect. However, the filter membrane is prone to deformation during transportation, which may cause the support tube to deform, resulting in looseness between the support tube and the mounting seat, and poor filtering effect. In addition, other components need to be connected at both ends of the support tube. After the traditional support tube is connected to the mounting seat, the length is fixed, non-adjustable, and the compatibility is poor. The size requirements of the support tube are high, so it needs to be improved. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", "fourth", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] See also Figures 1 to 6The utility model discloses a membrane stack reactor, comprising a mounting seat 1, a membrane assembly 5, a support tube 2 arranged outside the membrane assembly 5 and a handrail 3 for fixing the membrane assembly; the membrane assembly 5 and the support tube 2 are arranged in parallel on the mounting seat 1, and the membrane assembly 5 is connected to at least one support tube 2; the handrail 3 is sleeved on the outside of the membrane assembly 5 and fixed on the support tube 2; an adjusting member 4 is also provided at one end of the support tube 2 close to the mounting seat 1, and the length of the support tube 2 outside the mounting seat 1 can be adjusted by adjusting the tightness of the adjusting member 4. Specifically, the membrane filter assembly 5 is used to filter sewage. The membrane filter assembly 5 is composed of multiple membrane filter elements. There are tiny pores on the surface of the membrane filter assembly. When water flows through the membrane filter assembly 5, a pressure difference will be formed on both sides of the membrane filter element to push the water to flow through the densely distributed micropores on the surface of the filter membrane. The pores on the surface of the membrane filter assembly 5 only allow water molecules and small molecules to pass through, thereby filtering impurities in the water and allowing the filtered clean water to pass through. The clean water enters the membrane filter assembly 5 and then enters the mounting seat 1, and finally flows into the corresponding pipeline; secondly, when the water flow continuously flushes the surface of the membrane filter assembly 5, it can also flush away the impurities remaining on the surface of the membrane filter assembly 5. The shell of the membrane filter assembly 5 is usually a rigid body with a certain flexibility. Therefore, when the water flow flushes the surface of the membrane filter assembly 5, the surface of the membrane filter assembly 5 will not swing significantly, but will only float within a small range. In addition, the interior of the support tube 2 is a hollow structure, and the support tube 2 can serve as a pipe for discharging clean water and as an air guide pipe. The air guide pipe serves to direct the gas to the filter membrane assembly 5 to flush the accumulated sludge. At the same time, in order to further fix the filter membrane assembly 5, support tubes 2 are arranged on both sides of the filter membrane assembly 5 and handrails 3 are installed to better limit the swing range of the filter membrane assembly 5 to avoid large deviations of the filter membrane assembly 5 due to excessive water flow. At the same time, the handrails 3 can limit the filter membrane assembly when transporting the device to avoid the filter membrane assembly from being skewed or damaged during transportation.

[0040] Furthermore, the support tube 2 includes an air guide tube 21 and a clean water tube 22, which are respectively arranged on both sides of the filter membrane assembly 5 and are connected to the filter membrane assembly 5 through the mounting seat 1. When the membrane stack reactor is placed in the water body, the filter membrane assembly 5 absorbs clean water into the filter membrane component under capillary action, and impurities in the water are blocked outside the filter membrane component and adsorbed on the filter membrane assembly 5. The clean water flows through the channel inside the filter membrane component to the opening at the end of the membrane wire, and flows into the water production channel 6 in the mounting seat 1 through the opening. The clean water is then discharged through the clean water tube 22 connected to the mounting seat 1 to produce a clean water source. The filter membrane assembly 5 is installed on the mounting seat 1, and sludge will accumulate at its joint. The air guide tube 22 introduces external gas into the mounting seat 1, and the mounting seat 1 is connected to the filter membrane assembly 5, generating upward gas to blow away the accumulated sludge, making the membrane stack reactor cleaner.

[0041] Further, such as Figure 2-3As shown, when the support tube 2 is connected to the mounting seat 1, part of the length of the support tube 2 is inserted into the mounting seat 1, and an adjusting member 4 is provided at the port where the mounting seat 1 and the support tube 2 are connected, and the adjusting member 4 surrounds the outer periphery of the port of the mounting seat 1. Specifically, the adjusting member 4 is provided with an internal thread, and the mounting seat 1 is correspondingly provided with an external thread. The adjusting member 4 is threadedly connected to the mounting seat 1, and the adjusting member 4 is rotated to control the tightness. When the rotation loosens the connection between the adjusting member 4 and the mounting seat 1, the staff can appropriately pull out / deepen the support tube 2, such as Figure 3 , the support tube 2 can be pulled up from a to b to adjust the height of the support tube 2. The top of the support tube 2 is also connected to an external component. The height of the support tube 2 can be adjusted through the adjusting member 4, so as to connect external components of more heights and adapt to filter membrane components 5 of different heights, solving the problem of the support tube 2 being unadjustable and having poor compatibility in the prior art. When the filter membrane component 5 needs to be replaced, the adjusting member 4 can be loosened to remove the support tube 2, which is convenient for disassembly and assembly, so as to replace the filter membrane component 5 more efficiently.

[0042] Furthermore, a sealing member 401 is provided between the adjusting member 4 and the mounting seat 1. Preferably, the sealing member 401 can be made of elastic materials such as rubber and silicone to protect sewage from flowing into the connection between the support pipe 2 and the mounting seat 1. At present, when installing the support pipe 2, the size requirements of the support pipe 2 are relatively strict. A small error in the diameter of the support pipe 2 will cause difficulty in assembly. During transportation, collisions are inevitable, resulting in slight depressions on the surface of the support pipe 2. If the deformation of the support pipe 2 happens to be at one end close to the mounting seat 1, the deformation of the support pipe 2 can be compensated by rotating and tightening the adjusting member 4 and cooperating with the elastic sealing member 401. At the same time, the adjusting member 4 and the sealing member 401 can also compensate for the size error of the support pipe 2 when it leaves the factory, reducing the difficulty of assembly.

[0043] Further, such as Figure 4 As shown, it also includes a plurality of handrails 3 for fixing the membrane assembly 5. The handrails 3 are sleeved outside the membrane assembly 5 and fixed on the support tube 2. The handrails 3 include a first fixing portion 301 and a second fixing portion 302. The first fixing portion 301 is sleeved outside the membrane assembly 5, and the second fixing portion 302 is attached to the side wall of the support tube 2 and is connected with the first fixing portion 301. The handrails 3 limit the membrane assembly 5 to prevent the membrane assembly 5 from being greatly offset during transportation or operation. At the same time, the handrails 3 separate each membrane component in the membrane assembly 5 to prevent entanglement.

[0044] In addition, the surface of the first handrail 301 is constructed as a hollow structure. During transportation, winding materials (such as steel wire, elastic rope, etc.) can be passed through the hollow first handrail 301 to wrap around each filter membrane component, so that the filter membrane component will not undergo significant deformation during transportation, thereby better protecting the filter membrane assembly 5 from damage.

[0045] Specifically, a plurality of third fixing parts 303 may be provided in the hollow structure on the surface of the first handrail 301. The third fixing parts 303 are preferably T-shaped. During transportation, steel wires and elastic ropes may be wound around the third fixing parts 303 to prevent winding materials such as steel wires or elastic ropes from falling off.

[0046] Furthermore, the mounting seat 1 includes a mounting layer 101, an intermediate layer 102 and a base 103 from top to bottom, and the mounting layer 101, the intermediate layer 102 and the base 103 are snap-connected; wherein, a water production channel 6 is formed between the mounting layer 101 and the intermediate layer 102, and the clean water pipe 22 is connected to the water production channel 6; an air flow channel 7 is formed between the intermediate layer 102 and the base 103, and the air guide pipe 21 is connected to the air flow channel 7. The membrane stack reactor is placed in the water body, and water flows in all directions through the filter membrane assembly 5. A pressure difference is formed on both sides of the filter membrane to push the water to flow through the micropores densely distributed on the surface of the filter membrane, and the micropores of the filter membrane can only allow water molecules and other small molecules to pass through, thereby filtering out macromolecular organic matter such as bacteria and sediment in the water, thereby obtaining treated clean water. After filtering impurities in the water flow, the filter membrane assembly 5 adsorbs the clean water downward into the water production channel 6, and the water production channel 6 is connected to the clean water pipe 22, and the clean water is then discharged from the clean water pipe 22.

[0047] Further, such as Figure 2 As shown, a water production channel 6 is formed between the installation layer 101 and the middle layer 102, and an aeration pipe 8 extending toward the installation layer 101 is provided at the bottom of the middle layer 102. The two ends of the aeration pipe 8 are respectively connected to the filter membrane assembly 5 and the air flow channel 7 on the lower side of the middle layer 102, so that the air and the purified water are isolated from each other, and the aeration pipe 8 is connected to the filter membrane assembly 5. The air guide pipe 21 is connected to the air flow channel 7, and the air pump continuously provides air flow to the air guide pipe 21. Since the air flow channel 7 is formed between the middle layer 102 and the base 103, the air flow first flows from the air guide pipe 21 into the air flow channel 7, and then enters the aeration pipe 8 whose diameter suddenly decreases, while the air flow velocity remains unchanged, so that the gas pressure increases. The air flow after the pressure increase breaks up the sludge remaining at the connection between the filter membrane assembly 5 and the mounting seat 1, and improves the filtration quality. At the same time, the aeration pipe 8 isolates the air flow water production channel 6, and the cleaning and filtering water sources do not affect each other.

[0048] Further, such as Figure 6 As shown, in order to allow the gas in the air guide tube 21 to enter the air flow channel 7, a first extension section 101c is provided at the bottom of the installation layer 101, and correspondingly, the middle layer 102 is provided with an upward second extension section 102c. The first extension section 101c and the second extension section 102c are interference fit with each other, and have strong sealing performance, so that the air flow enters the air flow channel 7 from the air guide tube 21, and prevents the air flow from entering the water production channel 6.

[0049] Implementation Method 1

[0050] In one embodiment, Figure 1 As shown, since the membrane stack reactor includes a mounting seat 1, a membrane assembly 5, a support tube 2 and a handrail 3, the support tube 2 and the membrane assembly 5 are arranged on the mounting seat 1, and the membrane assembly 5 is also sleeved with a handrail 3. Since the material may encounter bumps during transportation, the handrail 3 is arranged outside the membrane assembly 5 to play a fixing role. In the prior art, the handrail 3 is usually integrally formed and difficult to disassemble. The utility model changes the handrail 3 into an assembly structure to facilitate the disassembly and replacement of the membrane component; in addition, the utility model also optimizes the handrail 3 into a hollow structure. During transportation, the material can be wrapped and fixed by the hollow first fixing part 301, so that the membrane assembly 5 is installed more stably and the possibility of skewness is reduced. In addition, the utility model adds an adjustment member 4 between the mounting seat 1 and the support tube 2, such as Figure 3 As shown, the bottom of the support tube 2 can be adjusted from a to b, and the adjusting piece can be tightened to adjust the height of the support tube 2 outside the mounting base 1, which reduces the requirements for the size of the support tube 2. The top of the support tube 2 is usually connected to an external pipeline. By adding the adjusting piece 4, the height of the support tube 2 can be adjusted, which makes it easier for the support tube 2 to adapt to external pipelines of different heights.

[0051] Implementation Method 2

[0052] like Figure 5 As shown, the utility model also provides another assembly method. In the prior art, in order to prevent the support tube 2 from tilting or collapsing, a connector 9 is usually connected to the top of the support tube 2. However, the length of the connector 9 is usually fixed. The prior art has strict requirements on the length of the connector 9. A long connector 9 may cause the two ends to be unable to connect with the support tube 2. Therefore, an adjustment member 4 is set between the support tube 2 and the mounting seat 1. By adjusting the tightness of the adjustment member 4 to raise the height of the support tube 2, when the produced connector 9 is slightly longer than the example between two support tubes 2, adjusting the height of one of the support tubes 2 can still be installed with the connector 9, reducing the staff's requirements for size. In addition, when the filter membrane assembly 5 shipped from the factory is higher, the height of the support tube 2 can also be increased so that the connector 9 can be capped, and the adaptability is higher. In addition, the assembly structure of the support tube 2 and the mounting seat 1 is convenient for replacing the components of the membrane stack reactor and for maintenance.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
