Description

Technical Field

[0001] This utility model belongs to the technical field of filtration devices, and relates to a device with automatic rotating water distribution function. Background Technology

[0002] As a pressure vessel, the core function of a membrane assembly is to house and secure the membrane elements, providing a closed, pressurized working environment for the membrane separation process. It mainly consists of a membrane cylinder, end caps, flanges, and a series of sealing components.

[0003] During membrane system operation, the membrane elements inside the membrane cartridges need to be periodically flushed to maintain their filtration performance. However, existing membrane cartridges generally lack a dedicated flushing water distribution mechanism, resulting in the flushing water flow often concentrating on the central membrane elements during flushing. This uneven fluid distribution ensures that the central membrane elements receive sufficient flushing, while the peripheral membrane elements suffer from insufficient flow distribution, leading to a significant reduction in flushing effectiveness. This problem further results in the accumulation of contaminants in the peripheral membrane elements, making them prone to clogging, and the flushing process lacks controllability, ultimately affecting the overall water production efficiency and stability of the membrane module. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a device with an automatic rotating water distribution function, which can improve the uniformity of rinsing effect and ensure the overall water production efficiency and stability of the membrane module.

[0005] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution: A device with an automatic rotating water distribution function includes a head, a housing inside the head, a water distributor rotatably mounted at the bottom of the housing, a plurality of water distribution pipes radially arranged in the water distributor, a partition dividing the inner cavity of the housing into an upper cavity and a lower cavity, and a floating sleeve penetrating the partition and sliding axially. The floating sleeve is driven downward by the start and stop water flow to connect the upper and lower cavities of the housing, and is driven upward by a reset member to reset. A plurality of push rods are arranged circumferentially at the bottom of the floating sleeve, and a plurality of inclined surfaces are arranged circumferentially at the top of the water distributor. When the push rods move downward, they drive the water distributor to rotate through the inclined surfaces.

[0006] In the above-mentioned device with automatic rotating water distribution function, an axial through hole is provided on the side wall of the floating sleeve. When the floating sleeve is in the initial position, the axial through hole is located above the partition plate. After the floating sleeve moves downward, the axial through hole and the inner cavity of the floating sleeve form a water flow channel. Preferably, multiple axial through holes are provided and are evenly distributed along the circumference.

[0007] In the above-mentioned device with automatic rotating water distribution function, the bottom opening of the floating sleeve is sealed by a valve plate, and a valve plate spring is provided between the valve plate and the top of the inner cavity of the floating sleeve. The valve plate spring provides a preload force to press the valve plate against the bottom of the floating sleeve to maintain the seal.

[0008] In the above-mentioned device with automatic rotating water distribution function, a sealing plate is fixed at the bottom of the valve plate, and the sealing plate abuts against the inner edge ring at the bottom of the floating sleeve to form a sealing connection; preferably, the sealing plate and the valve plate are fixed and pressed together by fasteners, the upper surface of the sealing plate seals the bottom of the valve plate, and the outer edge of the lower surface seals the inner edge ring at the bottom of the floating sleeve.

[0009] In the aforementioned device with automatic rotating water distribution function, a hanging plate is fixedly installed inside the housing, and the floating sleeve is hung on the bottom of the hanging plate by several tension springs, the tension springs forming a reset element for the floating sleeve.

[0010] In the aforementioned device with automatic rotating water distribution function, the push rod is fixed to the bottom of the push rod support block, the push rod support block is fixed to the bottom of the support block crossbeam, and the support block crossbeam is fixed to the bottom of the floating sleeve; preferably, the axis of the push rod is distributed in the horizontal direction, the push rod support blocks are arranged in pairs and spaced apart, the push rod passes through the push rod support block, and when the push rod moves downward, the push rod support block does not interfere with the water distributor.

[0011] In the aforementioned device with automatic rotating water distribution function, a guide rod is fixed in the middle of the hanging plate, the guide rod passes downward through the floating sleeve and the valve plate, and the valve plate spring is fitted onto the guide rod.

[0012] In the aforementioned device with an automatic rotating water distribution function, a ratchet tube is provided at the top of the water distributor, and a plurality of ratchet teeth are provided at the top of the ratchet tube, with the driving surface of the ratchet teeth forming the inclined surface. The ratchet tube can also be replaced with other mechanisms with inclined surfaces, such as helical gears.

[0013] Compared with the prior art, this utility model has the following advantages: 1. This utility model provides a device with an automatic rotating water distribution function. By adding an automatically rotating water distributor, the water distribution pipe can circumferentially and sequentially flush all membrane core areas, fundamentally solving the problem of uneven flushing effect between the center and the edge caused by traditional fixed water distribution methods. This effectively avoids the accumulation and clogging of contaminants in the peripheral membrane cores due to insufficient flushing. This utility model can more thoroughly remove contaminants from the membrane surface, significantly slow down the membrane fouling rate, thereby extending the cleaning cycle and service life of the membrane elements, maintaining the stability of the system's water production, and reducing long-term operation and maintenance costs.

[0014] 2. This invention cleverly utilizes the existing flushing water flow of the membrane system as a driving source, and achieves fully automatic operation through the cooperation of the floating sleeve, reset component, and mechanical transmission mechanism. The entire process requires no motor, sensor, or complex control system, has a compact structure, low energy consumption, reliable operation, and strong anti-interference ability, greatly reducing manufacturing costs and system complexity.

[0015] 3. The start-up and shutdown of this device are synchronized with the membrane system's flushing procedure, operating only during flushing. Its unique valve plate and through-hole design ensure the system's sealing during non-flushing conditions, while rapidly building water pressure and generating effective drive during flushing. The rotational motion is linked to the water flow start-up and shutdown, allowing for controllable flushing rhythm and intensity without affecting the normal filtration and water production function of the membrane module.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-2 : A device with an automatic rotating water distribution function includes a head 1, a housing 2 inside the head 1, a water distributor 3 rotatably mounted at the bottom of the housing 2, a plurality of water distribution pipes 4 arranged radially in the water distributor 3, a partition 5 dividing the inner cavity of the housing 2 into an upper cavity and a lower cavity, and a floating sleeve 6 passing through the partition 5 and sliding axially. The floating sleeve 6 is driven downward by the start and stop water flow to connect the upper and lower cavities of the housing 2, and is driven upward by a reset member 7 to reset. A plurality of push rods 8 are arranged circumferentially at the bottom of the floating sleeve 6, and a plurality of inclined surfaces 9 are arranged circumferentially at the top of the water distributor 3. When the push rods 8 move downward, they drive the water distributor 3 to rotate through the inclined surfaces 9.

[0018] The water distribution principle of this embodiment is as follows: In the initial standby state, the device is in a non-rinsing period or in the filtered water production state. At this time, no rinsing water flows in. Under the action of its reset member 7, the floating sleeve 6 is at the uppermost end of its axial stroke, and the push rod 8 is at the uppermost end with the floating sleeve 6, disengaging from the inclined surface 9 at the top of the water distributor 3. After the backwashing program is started, the rinsing water rushes into the floating sleeve 6 at a higher pressure and drives the floating sleeve 6 to move downward. As the floating sleeve 6 moves downward, the push rod 8 fixed at its bottom also moves downward. At the end of the stroke, the lower end of the push rod 8 abuts against and presses against the inclined surface 9 at the top of the water distributor 3. The inclined plane 9 generates a horizontal tangential force on the push rod 8, which is converted into driving torque, pushing the water distributor 3 to rotate by a predetermined angle. While the floating sleeve 6 moves downward, the upper and lower cavities of the housing 2 are connected, and the flushing water enters the lower cavity and the water distributor 3 in sequence, and finally sprays out from the water distribution pipe 4 to backwash the membrane core. After the flushing pulse time ends, the water inlet stops, the flushing water pressure disappears rapidly, and the floating sleeve 6 quickly returns to its initial state under the action of the reset member 7. When the next pulse water flow enters, the floating sleeve 6 repeats the above process, thereby driving the water distributor 3 to continue to rotate.

[0019] The specific structure of the floating sleeve 6 connecting the upper and lower cavities in this embodiment is as follows: An axial through hole 10 is provided on the side wall of the floating sleeve 6. When the floating sleeve 6 is in its initial position, the axial through hole 10 is located above the partition 5. After the floating sleeve 6 moves downward, the axial through hole 10 and the inner cavity of the floating sleeve 6 form a water flow channel. Preferably, multiple axial through holes 10 are provided and evenly distributed along the circumference. When the floating sleeve 6 is at its uppermost position, the upper and lower cavities are separated by the partition 5 and the outer wall of the floating sleeve 6. When the floating sleeve 6 moves downward, the axial through hole 10 moves downward accordingly. The lower end of the axial through hole 10 extends beyond the partition 5 and forms a water outlet gap. The flushing water can enter the floating sleeve 6 from the upper end of the axial through hole 10 and then enter the lower cavity from the lower end of the axial through hole 10, thereby connecting the upper and lower cavities.

[0020] The specific structure for the axial movement of the floating sleeve 6 in this embodiment is as follows: the bottom opening of the floating sleeve 6 is sealed by a valve plate 11, and a valve plate spring 12 is provided between the valve plate 11 and the top of the inner cavity of the floating sleeve 6. The valve plate spring 12 provides a preload force to press the valve plate 11 against the bottom of the floating sleeve 6 to maintain a seal. Its axial reciprocating motion is as follows: flushing water is injected into the floating sleeve 6 at a higher pressure through the axial through hole 10, applying downward pressure to the valve plate 11. This pressure can overcome the tension of the reset member 7, driving the entire floating sleeve 6 to move downwards.

[0021] To increase the sealing performance of the valve plate 11 and prevent water leakage and pressure loss, and to ensure that the flushing water drives the floating sleeve 6 to move rapidly downward with high pressure, a sealing plate 13 is fixed to the bottom of the valve plate 11. The sealing plate 13 abuts against the inner edge ring at the bottom of the floating sleeve 6 and forms a sealing connection. Preferably, the sealing plate 13 is fixed and pressed to the valve plate 11 by fasteners. The upper surface of the sealing plate 13 seals the bottom of the valve plate 11, and the outer edge of the lower surface seals the inner edge ring at the bottom of the floating sleeve 6.

[0022] The installation structure of the floating sleeve 6 is as follows: a hanging plate 14 is fixedly installed inside the housing 2, and the floating sleeve 6 is hung on the bottom of the hanging plate 14 by several tension springs, and the tension springs form the reset member 7 of the floating sleeve 6.

[0023] Furthermore, the push rod 8 is fixed to the bottom of the push rod support block 15, the push rod support block 15 is fixed to the bottom of the support block beam 16, and the support block beam 16 is fixed to the bottom of the floating sleeve 6; preferably, the axis of the push rod 8 is distributed in the horizontal direction, the push rod support blocks 15 are arranged in pairs and spaced apart, the push rod 8 passes through the push rod support block 15, and when the push rod 8 moves downward, the push rod support block 15 does not interfere with the water distributor 3.

[0024] Furthermore, in order to ensure that the floating sleeve 6 moves axially, a guide rod 17 is fixed in the middle of the hanging plate 14. The guide rod 17 passes downward through the floating sleeve 6 and the valve plate 11, and the valve plate spring 12 is fitted on the guide rod 17.

[0025] In this embodiment, the top of the water distributor 3 is provided with a ratchet tube 18, the top of the ratchet tube 18 is provided with a plurality of ratchet teeth, and the driving surface of the ratchet teeth forms the inclined surface 9.

[0026] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
