Description

Technical Field

[0001] The present invention relates to the technical field of flat ceramic membrane manufacturing, and in particular to a device for roughening the end-sealed bonding surface of a ceramic flat membrane. Background Art

[0002] Ceramic flat membranes, due to their advantages such as high temperature resistance, chemical corrosion resistance, high mechanical strength, and long service life, are increasingly being used in water treatment, food processing, biomedicine, environmental protection, and other fields. In practical applications, ceramic flat membranes typically require the assembly of multiple membrane modules to form a membrane assembly system. End seals are a critical step in the assembly process, and their quality directly impacts the sealing performance, operational stability, and service life of the membrane assembly. The primary purpose of end seals is to prevent short-circuiting and leakage of the treated fluid within the membrane assembly, ensuring that the fluid can be filtered or separated along the designed path through the membrane surface.

[0003] Most existing devices for roughening the bonding surface of ceramic flat membrane end seals suffer from insufficient bonding strength between the polymer and the plastic end seals. The flat ceramic membrane surface (Ra 0.1-0.5μm) is firmly bonded to the polymer, but the end seals are injection-molded from organic materials. Although roughened, they remain smooth. This results in a peel strength between the end seal and the polymer of only 0.1-0.2MPa (required to be >0.5MPa). Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that most of the devices for roughening the bonding surface of the ceramic flat membrane end seals have insufficient bonding strength between the polymer and the plastic end seals. The surface of the flat ceramic membrane (Ra 0.1-0.5μm) is firmly bonded to the polymer, and the end seal is injection-molded with organic materials. Although it has been roughened, the surface is still smooth, which also leads to the peel strength between the end seal and the polymer being only 0.1-0.2MPa (required to be >0.5MPa). A device for roughening the bonding surface of the ceramic flat membrane end seals is proposed.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a device for roughening the end-sealed bonding surface of a ceramic flat membrane, comprising a fixed plate, wherein the outer wall of the fixed plate is provided with two grooves, and the outer wall of the fixed plate is slidably connected to a connecting rod at the position corresponding to the groove, and the outer wall of the connecting rod is fixedly connected to a fixer, and a pressure sensor is installed on the outer wall of the bottom end of the fixer, and the outer walls on both sides of the fixed plate are fixedly connected to support plates, and an adjuster is installed on the outer wall of the support plate, and the outer wall of the adjuster is fixedly connected to an adjusting rod, and the outer wall of the adjusting rod is provided with a plurality of threaded holes.

[0006] Preferably, a connector is threadedly connected to a position of the threaded hole on the outer wall of the adjusting rod, a high-speed motor is fixedly connected to the outer wall of the connector, and a fan is fixedly connected to the driving end of the high-speed motor.

[0007] Preferably, the outer wall of the fan is fixedly connected to the outer wall of the connector, a drill bit is fixedly connected to the outer wall of the fan, and the outer wall of the drill bit is rotatably connected to the outer wall of the connector.

[0008] Preferably, the outer wall of the fixed plate is fixedly connected to a power supply, and the outer wall of the fixed plate is fixedly connected to a stepping motor driver.

[0009] Preferably, an automatic control device is fixedly connected to the outer wall of the fixed plate.

[0010] Preferably, a plurality of fixing rods are symmetrically fixedly connected to the outer wall of the bottom end of the fixing plate, and a suction cup is fixedly connected to the outer wall of the bottom end of the fixing rod.

[0011] Preferably, the groove depth ratio is 0.6-1.0, and the shape of the groove is a sinusoidal waveform similar to that of a gecko's paw.

[0012] Preferably, the drill bit is a hollow structure.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the present invention, a groove structure with a continuous sinusoidal waveform structure similar to the lines of a gecko's paw is adopted, which can greatly improve the bonding force between the polymer and the plastic end seal. Secondly, the addition of a pressure sensor and other structures can detect the processing status of the device in real time, thereby making the device more practical.

[0015] 2. In the present invention, a high-speed motor and a fan are used. The motor drives the drill bit to process the object while driving the fan to rotate. It can not only play the role of blowing dust, but also cool the drill bit in real time to prevent the excessive temperature from affecting the device. Secondly, the addition of a suction cup structure can improve the stability of the device during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Example 1: Figure 1-Figure 5 As shown, the present invention provides a technical solution: a roughening treatment device for the end-sealed bonding surface of a ceramic flat membrane, comprising a fixed plate 1, wherein the outer wall of the fixed plate 1 is provided with two grooves 101, and the outer wall of the fixed plate 1 is slidably connected to a connecting rod 2 corresponding to the position of the groove 101, the outer wall of the connecting rod 2 is fixedly connected to a fixture 3, and the outer wall of the bottom end of the fixture 3 is installed with a pressure sensor 4, the outer walls of both sides of the fixed plate 1 are fixedly connected to support plates 5, the outer wall of the support plate 5 is installed with a regulator 6, the outer wall of the regulator 6 is fixedly connected to an adjusting rod 7, the outer wall of the adjusting rod 7 is provided with a plurality of threaded holes 701, the depth ratio of the groove 101 is 0.6-1.0, and the shape of the groove 101 is a sine waveform similar to a gecko's foot, the outer wall of the fixed plate 1 is fixedly connected to a power supply 102, the outer wall of the fixed plate 1 is fixedly connected to a stepper motor driver 103, and the outer wall of the fixed plate 1 is fixedly connected to an automatic control device 104.

[0025] In this embodiment, the device is first placed in a suitable position, and then the end seal is placed in the groove 101. The device then automatically clamps the end seal, and then the automatic control device 104 is activated. Then, two connecting rods 2 are slid along the outer wall of the fixed plate 1. The movement of the connecting rod 2 drives the fixer 3 to move accordingly. The movement of the fixer 3 drives the pressure sensor 4 to move accordingly. The pressure sensor 4 receives the pressure change and feeds it back to the groove 101. At the same time, the pressure sensor 4 can also calculate the width-to-depth ratio of the groove 101 through AI intelligence. The AI ​​control process is sensing, decision-making, and then executing a closed loop. The depth-to-width ratio of the groove 101 is compared with the set parameters for processing. After processing is completed, the clamping device is released, and the groove bottom pop-up device is activated to automatically pop the workpiece to a certain height to facilitate manual placement of the end seal. This section mainly introduces the working principle of the processing structure. The groove structure with a continuous sine waveform structure similar to the lines on the gecko's paw can greatly improve the bonding strength between the polymer and the plastic end seal. Secondly, the addition of structures such as pressure sensors can detect the processing status of the device in real time, thereby making the device more practical.

[0026] Example 2: Figure 1-Figure 5 As shown, a connector 8 is threadedly connected to the position of the threaded hole 701 on the outer wall of the adjusting rod 7, a high-speed motor 9 is fixedly connected to the outer wall of the connector 8, a fan 10 is fixedly connected to the driving end of the high-speed motor 9, the outer wall of the fan 10 is fixedly connected to the outer wall of the connector 8, a drill bit 11 is fixedly connected to the outer wall of the fan 10, the outer wall of the drill bit 11 is rotatably connected to the outer wall of the connector 8, a plurality of fixing rods 12 are symmetrically fixedly connected to the outer wall of the bottom end of the fixing plate 1, a suction cup 13 is fixedly connected to the outer wall of the bottom end of the fixing rod 12, and the drill bit 11 is a hollow structure.

[0027] In this embodiment, the device is first placed in a suitable position, and then a plurality of suction cups 13 are adsorbed on the working plane. Then, the two adjusters 6 are adjusted to a suitable height. Then, the connector 8 is adjusted and installed on a suitable threaded hole 701. Then, the high-speed motor 9 is started, and the driving end of the high-speed motor 9 rotates to drive the drill bit 11 to work on the object, and at the same time drives the fan 10 to blow dust on the surface of the object and cool the drill bit 11. This part mainly introduces the working principle of the transmission structure, which adopts structures such as a high-speed motor and a fan. While the motor drives the drill bit to process the object, it drives the fan to rotate, which not only plays the role of blowing dust, but also can cool the drill bit in real time to prevent the high temperature from affecting the device. Secondly, adding a suction cup structure can improve the stability of the device during operation.

[0028] The working principle of this embodiment is as follows: first, the device is placed in a suitable position, then multiple suction cups 13 are adsorbed on the working plane, then the two adjusters 6 are adjusted to a suitable height, then the connector 8 is adjusted and installed on the appropriate threaded hole 701, and then the end seal is placed in the groove 101. Then the device automatically clamps the end seal, and then the automatic control device 104 is started, and then the two connecting rods 2 are slid along the outer wall of the fixing plate 1. The movement of the connecting rod 2 drives the fixer 3 to move accordingly, and the movement of the fixer 3 drives the pressure sensor 4 to move accordingly. The pressure sensor 4 receives the pressure change and feeds it back to the groove 101. At the same time, the pressure sensor 4 can also calculate the width-to-depth ratio of the groove 101 through AI intelligence, and compare the depth-to-width ratio of the groove 101 with the set parameters for processing. Then, the high-speed motor 9 is started, and the driving end of the high-speed motor 9 rotates to drive the drill bit 11 to work on the object, and at the same time drives the fan 10 to blow dust on the surface of the object and cool the drill bit 11. After the processing is completed, the clamping device is released, and the groove bottom pop-up device works to automatically pop out the workpiece to a certain height, which is convenient for manual removal and placement of the end seal.
