Description

Technical Field

[0001] This utility model relates to the field of membrane cleaning agent technology, and in particular to a mixing device for membrane cleaning agents that is easy to clean. Background Technology

[0002] Membrane cleaning agents, as key chemical agents for cleaning membrane systems, are widely used in water treatment, food and beverage, and pharmaceutical industries. Their mixing process directly affects the cleaning effect and membrane lifespan. In the membrane cleaning agent production industry, the mixing device, as a core production equipment, has a decisive impact on mixing efficiency, product quality, and production safety due to the ease of cleaning its inner wall. Especially in the crucial mixing stage of membrane cleaning agents, existing mixing devices are gradually revealing a series of significant limitations and technical problems when handling high-viscosity, easily residue-prone membrane cleaning agent raw materials.

[0003] Specifically, existing mixing devices face prominent problems such as inconvenience, low efficiency, and unstable quality during mixing operations. Residue on the inner wall can easily lead to batch-to-batch cross-contamination, affecting mixing uniformity; the cleaning process is time-consuming and labor-intensive, requiring manual intervention, which not only reduces production efficiency but also may lead to microbial growth risks due to residue accumulation. These problems directly result in reduced mixing efficiency, increased operational complexity, and difficulty in meeting the demands of large-scale, high-precision production. More seriously, residue accumulation not only significantly increases cleaning costs and time but may also pose potential risks to the overall quality and safety of the membrane cleaning agent, such as affecting membrane flux recovery and shortening membrane lifespan. Therefore, to address the numerous shortcomings of existing technologies, we urgently need an innovative, easy-to-clean membrane cleaning agent mixing device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for membrane cleaning agents that is easy to clean. This solves the problems in the prior art where residues on the inner wall can easily lead to cross-contamination between batches, affecting the uniformity of mixing. The cleaning process is time-consuming and labor-intensive, requiring manual intervention, which not only reduces production efficiency but may also lead to the risk of microbial growth due to residue accumulation.

[0005] To achieve the above objectives, this utility model provides a mixing device for membrane cleaning agents that is easy to clean. The device includes a barrel body, a top frame fixedly connected to the top of the barrel body, a rotating tube rotatably connected to one side of the inner side of the top frame, a stirring rod fixedly connected to the bottom of the rotating tube, mounting frames fixedly connected to both sides of the rotating tube, and side plates provided at the bottom of each mounting frame. The tops of the two side plates are detachably connected to the two mounting frames respectively. Scrapers are fixedly connected to opposite sides of the two side plates. The top of the rotating tube passes through the top frame, and a rotary joint is connected to the top of the rotating tube. A drive motor is fixedly connected to one side of the top of the top frame by bolts, and a connecting rod is rotatably connected to one side of the top of the top frame. The top of the connecting rod is drively connected to the output shaft of the drive motor, and one end of the connecting rod is engaged with the top of the rotating tube. A pump body is fixedly connected to one side of the top of the top frame by bolts, and the outlet of the pump body is connected to the top of the rotary joint. A spray bar is detachably connected to one side of the rotating tube.

[0006] One side of the rotating tube is connected to an installation tube, and a flange is fixedly connected to the top of the spray bar at one end of the installation tube, and the two flanges are fixedly connected by bolts.

[0007] Each of the two mounting frames has a threaded rod on one side, and one end of the threaded rod passes through the side wall and side plate of the mounting frame in sequence through a threaded groove.

[0008] The rotating tube has a first gear fitted on its top end, and the connecting rod has a second gear fitted on its top end, with the first gear and the second gear meshing together.

[0009] The top end of the rotating tube passes through the top of the top frame via a bearing sleeve, and the bottom end of the connecting rod is rotatably connected to the top of the top frame via a rotating shaft. The outlet of the pump body is connected to the top of the rotary joint via a connecting tube.

[0010] The barrel has a door that is hinged to the outside of the barrel, and a bottom valve is installed on the lower side of the barrel.

[0011] This invention discloses an easy-to-clean mixing device for membrane cleaning agents. By installing mounting frames on both sides of the rotating tube and designing a detachable connection between the side plates and the mounting frames, modular installation and removal of the scraper are achieved. This solves the problems of difficult cleaning of the inner wall and incomplete removal of residues in existing mixing devices. The side plates and scraper can be removed during the mixing stage to avoid interfering with the normal operation of the stirring rod. They can be quickly installed during the cleaning stage, enabling functional switching and improving the flexibility and efficiency of the equipment. The scraper, fixed to one side with two side plates facing away from each other, rotates and slides close to the inner wall of the tank under the drive of the rotating tube, effectively scraping away high-viscosity residues adhering to the inner wall, preventing long-term accumulation and scale formation. This reduces the frequency and intensity of manual cleaning, lowers the risk of batch-to-batch cross-contamination due to residues, and ensures the purity and quality stability of the subsequently mixed product. The spray bar is detachably connected to one side of the rotating tube and communicates with the pump body through a rotary joint and an internal channel of the rotating tube, enabling dynamic spraying of the cleaning liquid. The spray bar rotates with the rotating tube, allowing the water flow to cover all areas of the inner wall of the tank, avoiding cleaning dead spots and significantly improving the comprehensiveness and efficiency of cleaning. The pump body provides continuous and stable water pressure. The system ensures that the water jets from the spray bar have sufficient impact force, which, combined with the mechanical scraping action of the scraper, forms a highly efficient combined cleaning mechanism. This solves the problems of time-consuming, labor-intensive, and ineffective traditional cleaning methods, significantly shortening cleaning time and improving equipment turnover efficiency. The rotary joint allows for stable liquid delivery while the rotating tube rotates continuously, avoiding pipe entanglement or leakage and ensuring the continuity and reliability of the cleaning process. The drive motor is connected to the top of the rotating tube via a connecting rod, providing stable power output and ensuring controllable speed during stirring and cleaning. The overall structure integrates stirring, wall scraping, and spraying functions into the same rotating system, and the detachable components allow for quick switching between mixing and cleaning functions, avoiding the additional investment in dedicated cleaning equipment and reducing production costs. This device significantly improves the self-cleaning capability of the membrane cleaning agent mixing device, reduces manual intervention, lowers the risk of microbial growth, and improves production safety. It meets the needs of industries such as water treatment and pharmaceuticals for high-cleanliness and high-efficiency mixing equipment, effectively solving technical problems such as inconvenient cleaning, low efficiency, and unstable quality in existing technologies, and has good practicality and prospects for promotion.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figure 1-5 , A mixing device for an easy-to-clean membrane cleaning agent includes a barrel 1. A top frame 2 is fixedly connected to the top of the barrel 1, and a rotating tube 4 is rotatably connected to one side of the inner side of the top frame 2. A stirring rod 3 is fixedly connected to the bottom end of the rotating tube 4. Mounting frames 12 are fixedly connected to both sides of the rotating tube 4, and side plates 13 are provided at the bottom of each of the two mounting frames 12. The top ends of the two side plates 13 are detachably connected to the two mounting frames 12, respectively. Scrapers 17 are fixedly connected to the opposite sides of the two side plates 13. The top end of the rotating tube 4 passes through... A rotating joint 5 is connected to the top of the rotating tube 4 through the top frame 2. A drive motor 7 is fixedly connected to the top side of the top frame 2 by bolts. A connecting rod 9 is rotatably connected to the top side of the top frame 2. The top of the connecting rod 9 is connected to the output shaft of the drive motor 7. One end of the connecting rod 9 is engaged with the top of the rotating tube 4. A pump body 11 is fixedly connected to the top side of the top frame 2 by bolts. The outlet of the pump body 11 is connected to the top of the rotating joint 5. A spray bar 18 is detachably connected to one side of the rotating tube 4.

[0021] First, the membrane cleaning agent raw materials to be mixed are injected into the tank 1 through the top opening, ensuring that the amount of material does not exceed the safe capacity. Then, the drive motor 7, fixed to one side of the top frame 2, is started. The output shaft of the drive motor 7 drives the connecting rod 9 to rotate via a transmission connection. One end of the connecting rod 9 engages with the top of the rotating tube 4, thereby driving the rotating tube 4 to rotate around its central axis. A stirring rod 3 is fixedly connected to the bottom end of the rotating tube 4. The stirring rod 3 rotates synchronously with the rotating tube 4, thoroughly stirring and mixing the membrane cleaning agent raw materials in the tank 1 to ensure that the components are evenly dispersed and form a stable mixture. During the stirring process, the rotating... Mounting frames 12 are fixedly connected to both sides of pipe 4. During the mixing stage, the two side plates 13 are not installed on the mounting frames 12, and the scraper 17 and spray bar 18 are in a detached state, ensuring that the stirring rod 3 has sufficient space to move and avoid interfering with the normal mixing process. After mixing is complete, the mixed cleaning agent is discharged through the discharge port at the bottom of the barrel 1 for subsequent packaging or use. When cleaning the inner wall of the barrel 1 is required, the two side plates 13 are first detachably installed at the bottom of the mounting frames 12, so that the two side plates 13 are located on both sides of the rotating pipe 4, with the top of the side plates 13 fixedly connected to the mounting frames 12. Simultaneously, the spray bar... 18 is detachably connected to one side of the rotating tube 4, ensuring that the water inlet of the spray bar 18 is connected to the inside of the rotating tube 4; then the pump body 11, fixed to the top of the top frame 2, is started. The pump body 11 is connected to an external water source or cleaning solution through a pipe, and its outlet is connected to the top of the rotary joint 5. The rotary joint 5 is fixed to the top of the rotating tube 4 and rotates with it, continuously supplying external water to the inside of the rotating tube 4. The water flows through the hollow channel of the rotating tube 4 to the spray bar 18 and sprays out from the spray hole of the spray bar 18 to rinse the inner wall of the tank 1; at the same time, the drive motor 7 is started again, driving the rotating tube 4 to rotate through the connecting rod 9. The rotation of the rotating tube 4 is controlled by the mounting frame. 12 is transferred to the side plate 13, causing the two side plates 13 to drive the scraper 17 fixed on the opposite side to rotate synchronously around the axis. While rotating with the rotating tube 4, the scraper 17 slides close to the inner wall of the tank 1, scraping off the residue attached to the inner wall. Combined with the water flow sprayed by the spray bar 18, a combined cleaning mode of mechanical scraping and high-pressure rinsing is achieved, effectively removing high-viscosity and easily residual membrane cleaning agent residues. After cleaning, the drive motor 7 and pump body 11 are turned off, and the side plate 13 and spray bar 18 are disassembled for drying or separate cleaning. The entire cleaning process does not require manual entry into the tank 1 or manual cleaning with a scraper. The operation is simple and the cleaning is thorough.

[0022] Furthermore, one side of the rotating pipe 4 is connected to an installation pipe 19, and a flange 20 is fixedly connected to the top of the spray bar 18 at one end of the installation pipe 19. The two flanges 20 are fixedly connected by bolts. When cleaning is required, the spray bar 18 is aligned with the installation pipe 19 through the flanges 20, and the two flanges 20 are fastened together with bolts to form a reliable sealed connection structure, ensuring that the water will not leak from the interface during high-pressure transportation. This connection method is convenient to install and disassemble, has good sealing performance, and facilitates the quick installation and disassembly of the spray bar 18. At the same time, it supports the replacement of spray bars 18 with different spray angles or orifices to adapt to different cleaning needs, improving the versatility and maintenance convenience of the equipment.

[0023] Furthermore, each of the two mounting frames 12 is provided with a threaded rod 14 on one side, and one end of the threaded rod 14 passes through the side wall of the mounting frame 12 and the side plate 13 in sequence through the threaded groove. When installing the side plate 13, the side plate 13 is placed at the bottom of the mounting frame 12, and the threaded rod 14 is rotated to screw it into the threaded groove until the side plate 13 is pressed tightly, so as to realize the detachable fixed connection between the side plate 13 and the mounting frame 12. This structure is stable and can effectively prevent the side plate 13 from loosening or falling off due to centrifugal force or vibration during high-speed rotation, ensuring the safe operation of the scraper 17. At the same time, disassembly can be achieved by simply rotating the threaded rod 14 in the opposite direction, without the need for additional tools, which is simple to operate and improves maintenance efficiency and equipment reliability.

[0024] Furthermore, a first gear 6 is sleeved on the top of the rotating tube 4, and a second gear 8 is sleeved on the top of the connecting rod 9. The first gear 6 and the second gear 8 are meshed together. When the drive motor 7 starts and drives the connecting rod 9 to rotate, the second gear 8 rotates synchronously with the connecting rod 9. Through meshing with the first gear 6, the power is transmitted to the rotating tube 4, thereby driving the rotating tube 4 and the stirring rod 3 or side plate 13 and scraper 17 at its bottom to rotate. The gear transmission structure is stable, efficient, and has a strong load-bearing capacity. It can ensure that the rotating tube 4 maintains a stable speed when the load changes, avoids slippage or power interruption, and improves the stability and reliability of the stirring and cleaning process.

[0025] Furthermore, the top end of the rotating pipe 4 passes through the top of the top frame 2 via a bearing sleeve, and the bottom end of the connecting rod 9 is rotatably connected to the top of the top frame 2 via a rotating shaft. The outlet of the pump body 11 is interconnected with the top of the rotary joint 5 via a connecting pipe 10. The bearing sleeve provides stable rotational support for the rotating pipe 4, reduces rotational friction, and ensures its coaxiality and stability during long-term operation. The connecting rod 9 is rotatably connected to the top frame 2 via a rotating shaft, ensuring smooth and reliable transmission. The connecting pipe 10 serves as a transition pipe between the pump body 11 and the rotary joint 5, facilitating on-site installation and layout adjustment, while reducing pipe stress, preventing loosening or leakage of the interface due to vibration, and improving the sealing and durability of the entire liquid supply system.

[0026] Furthermore, a door 15 is rotatably connected to the outer side of the barrel 1 via a hinge, and a bottom valve 16 is installed on the lower side of the barrel 1. The door 15 can be rotated open around the hinge, which facilitates the addition of solid raw materials before mixing or visual inspection and auxiliary cleaning of the inside of the barrel 1, expanding the operating space and improving the convenience of feeding and maintenance. The bottom valve 16 is located on the lower side of the barrel 1 and serves as a discharge control device. It can be opened after mixing to achieve rapid and thorough discharge, reducing residue. Combined with the cleaning function of the scraper 17 and the spray bar 18, it further enhances the cleaning effect. At the same time, it provides a reliable seal when closed to prevent leakage, enhancing the practicality and operational safety of the equipment.

[0027] In summary.

[0028] When using a mixing device for membrane cleaning agents that is easy to clean, firstly, open the barrel 1 by hinged door 15 on one side of the barrel 1 to allow solid or liquid membrane cleaning agent raw materials to be added into the barrel 1. After adding the materials, close door 15 and ensure a seal. Then, start the drive motor 7 fixed to one side of the top of the top frame 2. The output shaft of the drive motor 7 drives the connecting rod 9 to rotate. The top of the connecting rod 9 is fitted with a second gear 8, which meshes with the first gear 6 fitted at the top of the rotating tube 4, thereby transmitting power to the rotating tube 4 and causing the rotating tube 4 to rotate around its central axis. The top of the rotating tube 4 passes through the top of the top frame 2 through a bearing sleeve. The bearing sleeve provides stable support, reduces rotational friction, and ensures smooth rotation. The bottom of the rotating tube 4... A stirring rod 3 is fixedly connected to the end of the barrel 1. During rotation, it thoroughly stirs and mixes the raw materials inside the barrel 1 to ensure uniform dispersion of each component. At this time, the two side plates 13 are not installed on the mounting frame 12, and the spray bar 18 is also in a disassembled state to avoid interfering with the stirring process. After the mixing is completed, the bottom valve 16 installed on the lower side of the barrel 1 is opened to discharge the mixed cleaning agent from the bottom of the barrel 1, achieving rapid and thorough discharge and reducing residue. When it is necessary to clean the inner wall of the barrel 1, the two side plates 13 are first placed at the bottom of the mounting frame 12, and the threaded rod 14 on one side of the mounting frame 12 is rotated so that it passes through the side wall of the mounting frame 12 and the side plate 13 in sequence through the threaded groove, firmly fixing the side plate 13 to prevent it from loosening during subsequent rotation. At the same time, the spray bar 18 is opened. The flange 20 at the top of the tube is aligned with the flange 20 on the mounting pipe 19, and the two flanges 20 are fastened together with bolts to form a reliable sealed liquid channel. Then, the pump body 11 fixed to the top of the top frame 2 is started. The outlet of the pump body 11 is connected to the top of the rotary joint 5 through the connecting pipe 10. The connecting pipe 10 facilitates pipeline layout and stress relief, and prevents leakage caused by vibration. The rotary joint 5 is fixed to the top of the rotating pipe 4 and rotates with it, continuously introducing the cleaning water delivered by the pump body 11 into the rotating pipe 4. The water flows through the hollow channel of the rotating pipe 4 to the spray bar 18 and is sprayed out from the spray hole of the spray bar 18 to perform high-pressure rinsing on the inner wall of the tank 1. At the same time, the drive motor 7 is started again, and the rotation is driven by the meshing of the first gear 6 and the second gear 8. The pipe 4 rotates, and the rotation of the rotating pipe 4 drives the installed side plate 13 to rotate synchronously through the fixed mounting frames 12 on both sides. The scraper 17 fixed on the opposite side of the side plate 13 rotates around the axis and slides close to the inner wall of the barrel 1 to scrape off the attached high-viscosity residue, realizing a combined cleaning mode of mechanical scraping and high-pressure water rinsing. The bottom end of the connecting rod 9 is rotatably connected to the top of the top frame 2 through the rotating shaft to ensure stable and reliable transmission. The entire cleaning process does not require manual entry into the barrel 1 or manual cleaning with a scraper. After cleaning, the drive motor 7 and pump body 11 are turned off, the threaded rod 14 is disassembled to remove the side plate 13, and the bolts on the flange 20 are loosened to remove the spray bar 18 for drying or separate cleaning. Then the door 15 is closed to prepare for the next mixing operation.The barrel 1 serves as the main container for mixing and cleaning, while the top frame 2 provides structural support, achieving functional integration. The rotating tube 4 passes through the top frame 2 via a bearing sleeve, ensuring smooth operation, reducing wear, and extending service life. The drive motor 7 drives the second gear 8 to rotate via the connecting rod 9. The second gear 8 meshes with the first gear 6, achieving stable power transmission. The gear transmission structure has strong load-bearing capacity, stable speed, and avoids slippage, improving the reliability of the mixing and cleaning process. The stirring rod 3 rotates with the rotating tube 4 to complete the mixing operation, ensuring uniform mixing. During the cleaning stage, the detachable connection between the mounting frame 12 and the side plate 13... The modular installation of the scraper 17 is achieved. The two side plates 13 are fixed to the mounting frame 12 by threaded rods 14, ensuring a firm connection that effectively resists centrifugal force and vibration during rotation, preventing loosening and ensuring operational safety. Simultaneously, it facilitates easy disassembly and assembly, improving maintenance efficiency. The scraper 17 fixed on the side plates 13 rotates and slides close to the inner wall of the barrel 1, effectively scraping away adhering high-viscosity residues, reducing manual cleaning workload, and solving the problems of severe inner wall residue and batch contamination in existing technologies. The spray bar 18 is connected to the mounting pipe 19 by bolts via flange 20, facilitating easy disassembly and assembly, ensuring good sealing, and supporting the replacement of different specifications of spray bars. The head is adapted to cleaning needs, improving the flexibility of the equipment; the pump body 11 delivers the cleaning fluid to the rotary joint 5 through the connecting pipe 10, and then enters the spray bar 18 through the internal channel of the rotary pipe 4, realizing dynamic spraying with a wide coverage area and no cleaning dead corners; the rotary joint 5 allows the rotary pipe 4 to stably supply liquid while rotating continuously, avoiding pipe entanglement; the scraper 17 and the spray bar 18 work together to form a highly efficient cleaning mode of mechanical scraping and high-pressure rinsing, significantly improving cleaning efficiency and cleanliness, and solving the problems of time-consuming, labor-intensive, and manual intervention required by traditional cleaning methods; the bottom valve 16 is set on one side of the lower part of the tank body 1, which facilitates rapid discharge after mixing.
