Description

Technical Field

[0001] This utility model relates to the field of filtration membrane technology, specifically to a membrane structure for a high-energy molecular momentum system. Background Technology

[0002] During the use of filtration membranes, a decrease in fluid permeability (flux) is a common problem. The main causes can be divided into two categories: membrane fouling and membrane structure damage. Membrane fouling refers to the accumulation of contaminants in the fluid on the membrane surface or inside the pores, leading to pore blockage or increased mass transfer resistance.

[0003] The existing utility model patent with announcement number CN222239638U discloses a single-core filter ultrafiltration membrane shell structure, including an ultrafiltration membrane shell. A first circular through-hole is formed at the top of one side of the ultrafiltration membrane shell, and an inlet pipe is fixedly connected to the first circular through-hole at the top of one side of the ultrafiltration membrane shell. A second circular through-hole is formed at the bottom of one side of the ultrafiltration membrane shell, and an outlet pipe is fixedly connected to the second circular through-hole at the bottom of one side of the ultrafiltration membrane shell. This utility model, by incorporating a rotating device and a cleaning brush, facilitates the rotation of the drive shaft via a motor body. The bottom of the drive shaft is fixedly connected to the top of the ultrafiltration membrane assembly, causing the drive shaft to rotate. The cleaning brush is connected to one side of the inner cavity of the ultrafiltration membrane shell, allowing the ultrafiltration membrane assembly to rotate on the surface of the cleaning brush. The cleaning brush cleans the surface of the rotating ultrafiltration membrane assembly, removing impurities and extending its service life.

[0004] The ultrafiltration membrane housing structure described above uses a brush to clean the surface of the ultrafiltration membrane to prevent the membrane pores from becoming clogged due to deposited impurities. However, the contact between the brush and the ultrafiltration membrane surface causes wear due to the relative motion between them. Furthermore, the brush's ability to remove oil film is limited by the characteristics of the oil film and the cleaning conditions, making it unable to effectively remove the oil film generated on the surface of the ultrafiltration membrane. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a high-energy molecular momentum system membrane removal structure, which solves the problems of being unable to remove oil films, having limited cleaning effects, and causing damage to ultrafiltration membranes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a membrane removal structure for a high-energy molecular momentum system includes a mounting frame, and a membrane removal mechanism is disposed above the mounting frame.

[0007] A limiting component is provided on the outside of the mounting bracket to limit the position of the mounting bracket;

[0008] The cleaning assembly includes an ultrasonic transducer fixedly installed at the top center of the mounting frame. The cleaning assembly also includes a guide plate fixedly installed inside the mounting frame. A motor is fixedly installed at the bottom of the mounting frame. A blade is inserted and installed on the outside of the motor shaft. A resonant brush is fixedly installed below the mounting frame.

[0009] Preferably, the limiting component includes a sliding groove disposed on the surface of the mounting bracket, a limiting rod is movably mounted below the mounting bracket, a lead screw is movably mounted at one end of the limiting rod, a spring is inserted through the outer side of the lead screw, a movable rod is inserted through the inner side of the lead screw, and a limiting plate is fixedly mounted at the front end of the movable rod.

[0010] Preferably, the slide is arranged in an "X" shape on the surface of the mounting frame with the center of the mounting frame as the reference, and the limiting rod is installed below the slide by bolts and nuts, and the limiting rod and the slide form a sliding connection.

[0011] Preferably, the lead screw and the limiting rod are connected by a threaded structure, the movable rod is connected to the lead screw by a sliding connection, one end of the spring contacts the front end of the hexagonal prism protrusion of the lead screw, and the other end of the spring contacts the limiting plate.

[0012] Preferably, the ultrasonic transducer housing is made of the same material as the mounting frame, the guide plate is installed in a ring shape on the inner side of the mounting frame with the center of the mounting frame as the reference, and the motor is fixedly installed inside the tubular protrusion structure at the bottom of the mounting frame.

[0013] Preferably, the blades of the propeller are arc-shaped, and the resonant brush is mounted in a ring below the mounting frame with the center of the mounting frame as the reference.

[0014] Beneficial effects

[0015] This invention provides a membrane-removing structure for a high-energy molecular momentum system. Compared with the prior art, it has the following advantages:

[0016] (1) The high-energy molecular momentum system membrane removal structure utilizes an ultrasonic transducer. The high-frequency vibrations generated by the transducer are transmitted to the solution via the mounting frame, and the resulting ultrasonic waves induce cavitation in the liquid. Alternating compression and rarefaction regions generate microcavitation bubbles, and the strong impact force and micro-jet energy released when these bubbles burst directly act on the surface of the ultrafiltration membrane, achieving efficient removal of the oil film due to its adhesion characteristics. Simultaneously, a motor drives an arc-shaped paddle to rotate, pushing the central solution to both sides. This, combined with an annular guide plate, guides the liquid to form a rotational motion, allowing the oil film and contaminants in the solution to be evenly dispersed over a larger area, avoiding local aggregation. The resonant brush vibrates synchronously with the mounting frame, further disturbing the solution flow field and keeping the oil film in a dynamically dispersed state. This ensures that the cavitation effect of the ultrasonic waves can continuously act on the surface of the fresh oil film, significantly improving the oil film removal efficiency.

[0017] (2) The high-energy molecular momentum system membrane removal structure uses the sliding connection between the X-shaped groove and the limiting rod in the limiting component to flexibly adjust the position of the mounting frame. The cooperation between the screw and the spring forms a soft connection structure, concentrating the vibration energy of the ultrasonic transducer on the mounting frame and cleaning components, reducing the transmission to the filter housing, and avoiding insufficient cleaning effect due to energy loss. The ultrasonic transducer housing and the mounting frame are made of the same material to ensure that the vibration energy is uniformly transmitted to the solution, while reducing the intensity of ultrasonic waves in the liquid and preventing direct damage to the ultrafiltration membrane from high-intensity vibration. In addition, the annular distribution of the resonant brush and the arc design of the blades work together to keep the contaminants that cannot pass through the membrane moving under the rotating flow field and vibration disturbance, which not only avoids the deposition of contaminants to form a new clogging layer, but also reduces the hard friction between the traditional brush and the membrane surface, fundamentally solving the problem of membrane damage during the cleaning process, while continuously improving the overall effect through dynamic cleaning.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a membrane removal structure for a high-energy molecular momentum system, including a mounting frame 1, and a membrane removal mechanism 2 disposed above the mounting frame 1.

[0025] A limiting component 21 is disposed on the outside of the mounting frame 1 to limit the position of the mounting frame 1. The limiting component 21 includes a sliding groove 211 disposed on the surface of the mounting frame 1. A limiting rod 212 is movably mounted on the lower part of the mounting frame 1. A lead screw 213 is movably mounted on one end of the limiting rod 212. A spring 214 is inserted through the outside of the lead screw 213. A movable rod 215 is inserted through the inside of the lead screw 213. A limiting plate 216 is fixedly mounted on the front end of the movable rod 215. The sliding groove 211 is connected to the mounting frame 1. The center is set in an "X" shape on the surface of the mounting bracket 1. The limiting rod 212 is installed below the slide groove 211 by bolts and nuts, and the limiting rod 212 and the slide groove 211 form a sliding connection. The lead rod 213 and the limiting rod 212 form a movable connection through a threaded structure. The movable rod 215 and the lead rod 213 form a sliding connection. One end of the spring 214 contacts the front end of the hexagonal prism protrusion of the lead rod 213, and the other end of the spring 214 contacts the limiting plate 216.

[0026] Specifically, the position of the limiting rod 212 is adjusted by bolts and nuts so that the limiting plate 216 contacts the inner wall of the filter. Then, the screw 213 is rotated. Since the rotation angle of the limiting rod 212 is fixed, the limiting plate 216 contacts the inner wall of the filter. When the screw 213 rotates, it will compress the spring 214 with the limiting plate 216. The elasticity of the spring 214 forms a soft connection between the mounting bracket 1 and the filter, preventing the vibration energy generated by the ultrasonic transducer 221 from being transmitted to the filter. The limiting component 21 restricts the mounting bracket 1 to the feed liquid side of the ultrafiltration membrane.

[0027] The cleaning assembly 22 includes an ultrasonic transducer 221 fixedly installed at the top center of the mounting frame 1. The cleaning assembly 22 also includes a guide plate 222 fixedly installed inside the mounting frame 1. A motor 223 is fixedly installed at the bottom of the mounting frame 1. A blade 224 is inserted and installed on the outside of the shaft of the motor 223. A resonant brush 225 is fixedly installed below the mounting frame 1. The outer shell of the ultrasonic transducer 221 is made of the same material as the mounting frame 1. The guide plate 222 is installed in a ring shape inside the mounting frame 1 with the center of the mounting frame 1 as the reference. The motor 223 is fixedly installed inside the tubular protrusion structure at the bottom of the mounting frame 1. The blades of the blade 224 are arc-shaped. The resonant brush 225 is installed in a ring shape below the mounting frame 1 with the center of the mounting frame 1 as the reference.

[0028] Specifically, the ultrasonic transducer 221, model DWP4-4540-68LB, can cause the mounting frame 1 to vibrate. The mounting frame 1 can expand the ultrasonic radiation area and reduce the ultrasonic intensity in the liquid, preventing damage to the ultrafiltration membrane due to excessive ultrasonic intensity. As the liquid moves downward, it will rotate under the restriction of the guide plate 222. The motor 223 can drive the blade 224 to rotate, pushing the solution at the center to both sides, so that substances in the solution that cannot pass through the ultrafiltration membrane are away from the center of the ultrafiltration membrane. The ultrasonic waves generated by the ultrasonic transducer 221 are transmitted to the interior of the solution and then to the ultrafiltration membrane to clean the ultrafiltration membrane. At the same time, the resonant brush 225 will vibrate with the mounting frame 1 to disturb the solution, so that substances in the solution that cannot pass through the ultrafiltration membrane are always in motion. All contents not described in detail in this specification are prior art known to those skilled in the art.

[0029] During operation, the position of the limiting rod 212 in the slide groove 211 is first adjusted by bolts and nuts so that the limiting plate 216 contacts the inner wall of the filter. Then, the lead screw 213 is rotated. Since the rotation angle of the limiting rod 212 is fixed, the lead screw 213 will squeeze the spring 214 together with the limiting plate 216 when it rotates. With the help of the elasticity of the spring 214, the mounting frame 1 and the filter form a soft connection, avoiding the transmission of vibration energy, thereby stably limiting the mounting frame 1 to the raw liquid side of the ultrafiltration membrane. Then, the ultrasonic transducer 221 is started and generates high-frequency vibration. This vibration is transmitted to the surrounding solution through the mounting frame 1 to form ultrasonic waves. When ultrasound propagates in a solution, it generates alternating regions of compression and rarefaction, forming tiny bubbles (cavitation bubbles). These bubbles continuously grow, contract, and eventually burst under the influence of ultrasonic vibration. The bursting releases enormous energy, generating a strong impact force and microjets, which can effectively remove contaminants (including stubborn oil films) adhering to the surface of the ultrafiltration membrane. Simultaneously, the vibrational energy of the ultrasound can loosen and remove blockages within the membrane pores, achieving deep cleaning of both the surface and interior of the ultrafiltration membrane. During this process, the liquid rotates downwards due to the constraint of the guide plate 222; the motor 223 drives the paddle 224 to rotate, pushing the solution at the center to both sides, causing substances that cannot pass through the ultrafiltration membrane to move away from the center; the resonant brush 225 further agitates the solution with the vibration of the mounting frame 1, keeping substances in the solution that cannot pass through the ultrafiltration membrane constantly in motion. This continuous motion prevents contaminants from depositing and accumulating on or near the ultrafiltration membrane surface, forming a new clogging layer. It ensures that the impact force and microjets generated by the ultrasound can continuously act on fresh contaminants on the membrane surface, while reducing the probability of already peeled contaminants re-attaching to the membrane surface. In conjunction with the ultrasonic cleaning action, it significantly improves the overall membrane removal and cleaning effect.
