Technical Field
[0001] This utility model relates to the field of tubular membrane equipment technology, and in particular to a skid-mounted, movable tubular membrane equipment. Background Technology
[0002] Limitations of Traditional Membrane Separation Technology: Traditional membrane separation equipment (such as flat sheet membranes and hollow fiber membranes) is typically fixed, bulky, and heavy, requiring dedicated plant facilities or infrastructure. This type of equipment is significantly inadequate in the following scenarios: Poor flexibility: unable to be quickly relocated or adapted to temporary needs (such as emergency water treatment or field operations). High deployment costs: reliant on fixed pipelines, power, and civil engineering, resulting in large initial investments and long development cycles. Complex maintenance: equipment downtime for maintenance requires disassembly or production interruption, affecting continuity. Market Demand for Mobile Equipment: With the development of environmental protection, energy, and industrial sectors, the demand for flexible and efficient separation equipment is increasing: Emergency treatment: drinking water purification after natural disasters (such as earthquakes and floods), emergency treatment of industrial wastewater. Distributed scenarios: oilfield produced water reuse, temporary mine drainage, agricultural irrigation water quality improvement, and other decentralized scenarios. Resource recovery: biogas purification, industrial waste gas recovery, and other scenarios requiring rapid on-site deployment. Scientific research and experimentation: pilot-scale experiments or temporary R&D projects requiring mobile equipment. Advantages of Skid-Mounted Design: Skid-mounted design integrates core equipment (membrane modules, pumps, valves, control systems, etc.) into a single movable frame, offering the following advantages: High Integration: All functional modules (pretreatment, membrane separation, cleaning, control) are integrated into a single skid, saving space. Rapid Deployment: Operation can be completed within hours via hoisting or forklift transport, requiring no complex installation. Strong Environmental Adaptability: Designed to be rainproof, sunproof, and corrosion-resistant, adaptable to harsh outdoor conditions (such as high temperature, high humidity, and dust). Modular Expansion: Skids can be added as needed (such as multi-stage membrane modules, chemical cleaning units), flexibly adjusting processing capacity. Unique Value of Tubular Membrane Technology: Advantages of Tubular Membrane Technology Compared to other membrane forms (such as flat sheet membranes and hollow fiber membranes): High Pressure Resistance and Anti-fouling: The tubular structure can withstand higher pressures (bar), suitable for processing high-turbidity and high-viscosity materials. Strong Chemical Stability: Can be made of corrosion-resistant materials (such as PVDF and ceramic membranes), resistant to acid, alkali, and oxidant cleaning. Easy to clean and maintain: Tubular membranes can be replaced individually, and mechanical cleaning (such as sponge ball rinsing) or chemical cleaning is more efficient. Wide range of applicable media: Can be used for water treatment (ultrafiltration, nanofiltration, reverse osmosis), gas separation (air, biogas), organic solvent recovery, etc.
[0003] In traditional skid-mounted tubular membrane equipment, the circulating pump is usually fixed in the frame and connected to the pipeline by bolts or welding. This design has problems such as difficult maintenance, high replacement costs, and poor flexibility. When the circulating pump fails, a large number of pipelines and electrical lines need to be disassembled, which is time-consuming and labor-intensive. The integrated design of the pump body and pipeline means that replacement requires a complete shutdown, which affects the continuity of production. It is not possible to quickly replace different models of pumps to adapt to changes in flow or pressure. The transportation stability is insufficient. During the equipment movement, the circulating pump and other key components are prone to loosening or damage due to vibration. Therefore, we propose a skid-mounted, mobile tubular membrane equipment to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a skid-mounted, movable tubular membrane device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A skid-mounted, movable tubular membrane device includes: an outer frame and a circulation pump. Two fixing plates are fixedly installed on both sides of the circulation pump, and screws are threadedly connected to the fixing plates and the screws are threadedly connected to the outer frame. A tubular membrane body is disposed inside the outer frame. Two top plates are fixedly installed on the tubular membrane body. Two fixing blocks are fixedly installed on the circulation pump. A connecting block is fixedly installed on the top of each fixing block. A rotating disk is rotatably installed on the bottom of the top plate. A limiting disk is rotatably installed on the rotating disk. Multiple insertable round blocks are fixedly installed on the bottom of the limiting disk. The insertable round blocks are inserted into the connecting blocks. A buckle is slidably installed inside each insertable round block. A spring is fixedly installed on one side of each buckle and is fixedly installed inside the insertable round block. A slanted concave hole matching the buckle is opened on the connecting block. Two clamping and limiting components are disposed on the top of the outer frame. A second limiting component is disposed on the connecting block.
[0007] Preferably, the clamping and limiting assembly includes: a sliding clamp and a fixed clamp. A plurality of insert plates are fixedly installed on one side of the sliding clamp, and the insert plates are inserted into the fixed clamp. A pull rod is slidably installed in the fixed clamp. A plurality of connecting plates are fixedly installed on the outside of the pull rod. A plurality of second buckles are slidably installed in the sliding clamp. The plurality of connecting plates are respectively fixedly connected to the corresponding second buckles. A second spring is fixedly installed at the top of the second buckle. The second spring is fixedly installed in the sliding clamp. A limiting oblique groove matching the second buckle is provided on the insert plate.
[0008] Preferably, the second limiting component includes: a limiting frame and multiple side pressure plates, multiple rotating blocks are fixedly installed at the bottom of the connecting block, and the multiple side pressure plates are rotatably installed on the corresponding rotating blocks. The limiting frame is slidably installed on the outside of the fixed block. The limiting frame has limiting recesses that match the side pressure plates, and the inner side of the limiting frame has limiting slots that match the buckle.
[0009] Preferably, the insert block has a sliding groove that matches the buckle, the buckle is slidably installed in the sliding groove, the spring is fixedly installed in the sliding groove, a round rod is fixedly installed at the top of the buckle, the insert block has a sliding recessed hole that matches the round rod, the rotating disk has an arc-shaped hole, and the round rod is slidably installed in the arc-shaped hole.
[0010] Preferably, the fixed clamp has a sliding square groove that matches the second buckle, the second spring is fixedly installed in the sliding square groove, a moving groove that matches the connecting plate is opened on one side of the sliding square groove, a sliding groove that matches the pull rod is opened in the fixed clamp, a threaded ring is threadedly connected to the pull rod, and a threaded groove that matches the threaded ring is opened at the top of the fixed clamp.
[0011] Preferably, a T-shaped block is fixedly installed at the bottom of the sliding clamp, a sliding groove matching the T-shaped block is opened at the top of the outer frame, a square groove matching the insert plate is opened on the fixed clamp, multiple universal wheels are fixedly installed at the bottom of the outer frame, and a control valve is fixedly installed on the tubular membrane body.
[0012] Preferably, a T-shaped ring is fixedly installed at the top of the rotating disk, a T-shaped groove matching the T-shaped ring is opened at the bottom of the top plate, an L-shaped ring is fixedly installed at the bottom of the rotating disk, and the limiting disk is installed inside the L-shaped ring.
[0013] In this utility model, a skid-mounted movable tubular membrane device is described. The circulating pump is fixed in a suitable position within the outer frame via screws and threaded connections. The circulating pump is securely mounted on the outer frame. By rotating the rotating disk, the T-ring rotates within the T-ring groove, and the L-ring provides rotational support for the limiting disk, ensuring stable rotation of both the rotating disk and the limiting disk. Multiple insert blocks are fixedly installed at the bottom of the limiting disk. These insert blocks are inserted into the connecting block at the top of the fixed block on the circulating pump. Each insert block has a sliding groove that matches a latch. When the rotating disk rotates, the arc-shaped hole drives the round rod to slide within the sliding groove, which in turn drives the latch to slide within the sliding groove, compressing the spring and causing the latch to retract into the insert block. Subsequently, the limiting frame is pushed... The fixed block slides on the outside, and the limiting recess on the limiting frame contacts the side pressure plate. As the limiting frame moves, the side pressure plate rotates on the rotating block, making the structural connection tighter. At the same time, the limiting frame has a limiting slot that matches the buckle. When the limiting frame moves to the appropriate position, the limiting slot is opposite to the buckle. At this time, the rotating disk is released, the spring returns to its deformation, and pushes the buckle into the limiting slot, further locking the connection between the insert block and the connecting block, completing the stable connection between the tubular membrane body and the circulating pump. The sliding clamp is pushed, and the T-shaped block slides in the sliding groove to ensure that the sliding clamp moves smoothly. The insert plate is inserted into the square groove of the fixed clamp, and the pull rod is pulled. The pull rod slides in the sliding groove, and at the same time, it drives the connecting plate to move in the moving groove.
[0014] In this utility model, a skid-mounted movable tubular membrane device is described. A connecting plate drives a second latch to slide within a sliding groove, compressing a second spring and causing the latch to retract into the sliding clamp. Once the insert plate is fully inserted into the fixed clamp, the pull rod is released, the second spring returns to its original shape, and pushes the latch into the limiting oblique groove on the insert plate, completing the clamping and fixing of the tubular membrane body by the sliding and fixed clamps. Rotating the threaded ring connects it to the threaded groove at the top of the fixed clamp, fixing the position of the pull rod and preventing the latch from accidentally loosening. Multiple casters are fixedly installed at the bottom of the outer frame. Utilizing the rolling characteristics of the casters, the skid-mounted movable tubular membrane device can be easily moved to the desired working position, and the tubular membrane body is fixedly mounted... There is a control valve. By operating the control valve, the working parameters of the tubular membrane equipment can be adjusted to achieve the filtration and separation operations of the tubular membrane to meet different process requirements. To disconnect the tubular membrane body from the circulating pump: pull the limiting frame to separate the limiting slot from the buckle one, and the limiting recess from the side pressure plate. The side pressure plate rotates under the action of gravity to release the lateral compression. Rotate the rotating disk to make the buckle one disengage from the connecting block, separating the tubular membrane body from the circulating pump. To release the tubular membrane body from the clamping fixation: rotate the threaded ring to separate it from the threaded groove, pull the pull rod to make the buckle two disengage from the limiting oblique slot, push the sliding clamp to pull out the insert plate, and release the clamping fixation. To disconnect the circulating pump from the outer frame: unscrew the screws to release the threaded connection between the fixing plate and the outer frame, and remove the circulating pump.
[0015] This utility model has a reasonable structural design, which shortens the disassembly time of the circulating pump to less than five minutes, reduces labor costs and downtime losses, is flexible and adaptable, and can quickly replace different models of circulating pumps to adapt to different working conditions. The modular design reduces the types of spare parts, reduces long-term maintenance costs, and ensures transportation stability. The clamping and limiting components and the second limiting components ensure the stability of key components during the movement of the equipment and prevent damage. Attached Figure Description

[0029] In this embodiment, during use, the circulation pump 6 is fixed in a suitable position inside the outer frame 1 by screw 7 threadedly connected to the outer frame 1, and the circulation pump 6 is securely installed on the outer frame 1. By rotating the rotating disk 16, the T-ring 18 rotates in the T-ring groove, and the L-ring 17 provides rotational support for the limiting disk, ensuring that the rotating disk 16 and the limiting disk can rotate stably. Multiple insert round blocks 19 are fixedly installed at the bottom of the limiting disk. The insert round blocks 19 are inserted into the connecting block 12 at the top of the fixing block 11 on the circulation pump 6. The insert round blocks 19 have a sliding groove that matches the buckle 21. When the rotating disk 16 is rotated, the arc-shaped hole drives the round rod 20 to slide in the sliding groove. The round rod 20 then drives the buckle 21 to slide in the sliding groove, compressing the spring 22, causing the buckle 21 to retract into the insert round block. Inside block 19, the limiting frame 13 is then pushed to slide outside the fixed block 11. The limiting recess on the limiting frame 13 contacts the side pressure plate 15. As the limiting frame 13 moves, the side pressure plate 15 rotates on the rotating block 23, making the structural connection tighter. At the same time, the inner side of the limiting frame 13 is provided with a limiting slot that matches the buckle 21. When the limiting frame 13 moves to the appropriate position, the limiting slot is opposite to the buckle 21. At this time, the rotating disk 16 is released, the spring 22 returns to its deformation, and the buckle 21 is pushed into the limiting slot, further locking the connection between the insert block 19 and the connecting block 12, completing the stable connection between the tubular membrane body 5 and the circulating pump 6. Then, the sliding clamp 3 is pushed, and the T-shaped block 29 slides in the sliding groove to ensure that the sliding clamp 3 moves smoothly. The insert plate 10 is then inserted into the fixed block 11. Pulling the pull rod 26 within the square groove of the fixed clamping plate 4 causes the pull rod 26 to slide within the sliding groove, simultaneously moving the connecting plate 28 within the moving groove. The connecting plate 28 then causes the second buckle 27 to slide within the sliding square groove, compressing the second spring 25 and causing the second buckle 27 to retract into the sliding clamping plate 3. When the insert plate 10 is fully inserted into the fixed clamping plate 4, releasing the pull rod 26 causes the second spring 25 to return to its original shape, pushing the second buckle 27 into the limiting oblique slot on the insert plate 10, thus completing the clamping and fixing of the tubular membrane body 5 by the sliding clamping plate 3 and the fixed clamping plate 4. Rotating the threaded ring 24 causes the threaded ring 24 to be threadedly connected to the threaded groove at the top of the fixed clamping plate 4, fixing the position of the pull rod 26 and preventing the second buckle 27 from accidentally loosening. Multiple universal wheels 2 are fixedly installed at the bottom of the outer frame 1, utilizing the rolling motion of the universal wheels 2... The mobile design allows for easy movement of the skid-mounted, movable tubular membrane equipment to the desired working position. A control valve 9 is fixedly installed on the tubular membrane body 5. By operating the control valve 9, the operating parameters of the tubular membrane equipment can be adjusted to achieve filtration, separation, and other operations to meet different process requirements. To disconnect the tubular membrane body from the circulating pump: pull the limiting frame 13 to separate the limiting slot from the first buckle 21, and the limiting recess from the side pressure plate 15. The side pressure plate 15 rotates under gravity, releasing the lateral compression. Rotate the rotating disk 16 to disengage the first buckle 21 from the connecting block 12, separating the tubular membrane body 5 from the circulating pump 6. To release the clamping fixation of the tubular membrane body: rotate the threaded ring 24 to separate it from the threaded groove, and pull the pull rod 26 to disengage the second buckle 27 from the limiting oblique slot.Push the sliding clamp 3 to pull out the insert plate 10, releasing the clamping fixation and disconnecting the circulation pump from the outer frame: unscrew screw 7 to disconnect the threaded connection between the fixing plate 8 and the outer frame 1, and remove the circulation pump 6.
