DETAILED DESCRIPTION

[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1 - Fig.10 The system includes an ultrafiltration controller 11 disposed in a system body 1, an ultrafiltration membrane group 12 fixedly mounted on the upper end of the ultrafiltration controller 11, and an ultrafiltration control system mounted in the ultrafiltration controller 11. The right end of the ultrafiltration membrane group 12 is fixedly connected to an ultrafiltration pipeline 2 connected thereto, the right end of the ultrafiltration pipeline 2 is sealedly connected to a liquid passage 3, and the outer end of the liquid passage 3 is provided with a sealing connection structure 4 matched with the ultrafiltration pipeline 2;

[0035] A sealing thread groove 21 is provided at the right end of the ultrafiltration pipe 2, and the sealing connection structure 4 includes an adapter waist sleeve 41 fixedly connected to the outer end of the liquid pipe 3, which can be fixedly connected by welding, gluing, threaded connection, etc., and the outer end of the adapter waist sleeve 41 is fixedly connected to a squeeze ring 43, and the outer end of the squeeze ring 43 is fixedly connected to a sealing thread sleeve 42, and the sealing thread sleeve 42 is meshed with the sealing thread groove 21, and the left end of the liquid pipe 3 is fixedly connected to a liquid suction sensing sleeve 44, and the left end of the liquid suction sensing sleeve 44 is fixedly connected to the adapter waist sleeve 41;

[0036] The ultrafiltration control system comprises an ultrafiltration control processing unit, the input end of which is connected to an instruction acquisition unit, an ultrafiltration parameter acquisition unit and a leakage sensing unit, and the output end of which is connected to an ultrafiltration control unit, an ultrafiltration data display unit and a leakage alarm unit;

[0037] The input end of the instruction acquisition unit is respectively connected to the touch display and the control button signal arranged at the front end of the ultrafiltration controller 11, and the input end of the ultrafiltration parameter acquisition unit is connected to the signal of each component arranged in the system body 1. The components in the system body 1 include but are not limited to the pump, the ultrafiltration membrane group 12, the pressure control system and other components, and data can be collected from these components to judge the operating state of the system body 1. The input end of the leakage sensing unit is connected to the moisture absorption conductive contact signal arranged in the liquid absorption sensing sleeve 44;

[0038] The moisture absorption conductive contact pieces are fixedly embedded on the left and right sides of the liquid absorption sensing sleeve 44. The liquid absorption sensing sleeve 44 is filled with absorbent cotton with impurity particles. After the absorbent cotton with impurity particles is saturated with water, a conductive state will be formed, and then the two moisture absorption conductive contact pieces will be triggered to send a conductive signal to the leakage sensing unit.

[0039] The output end of the ultrafiltration control unit is connected to the signals of the components arranged in the system body 1. The components in the system body 1 include but are not limited to the pump, the ultrafiltration membrane group 12, the pressure control system and other components, which can be controlled to realize the application function of the system body 1. The output end of the ultrafiltration data display unit is connected to the touch display signal arranged at the front end of the ultrafiltration controller 11, and the output end of the leakage alarm unit is connected to the alarm signal arranged on the ultrafiltration controller 11. Through the cooperation of the sealing threaded sleeve 42, the squeezing ring 43, the liquid suction sensing sleeve 44 and the leakage sensing unit, during the application of the system body 1, on the one hand, through the threaded meshing of the sealing threaded sleeve 42 and the sealing thread groove 21 The two parts can cooperate to effectively maintain the stability and effectiveness of the sealed connection between the ultrafiltration pipeline 2 and the liquid passing pipe 3, and improve the impact resistance of the liquid passing pipe 3. On the other hand, when the sealed connection between the ultrafiltration pipeline 2 and the liquid passing pipe 3 is damaged and leaking, the leakage problem can be discovered in time through the triggering effect of the liquid suction sensing sleeve 44 and the leakage sensing unit, thereby avoiding the problem of excessive liquid leakage polluting the application environment of the system body 1, ensuring the environmental protection and safety of the system body 1 during the application process, and through the setting of the leakage alarm unit, it can remind the user of the leakage, improve the response efficiency of the user to the leakage problem, and implement emergency repair measures on the system body 1 in time to avoid other economic losses.

[0040] It should be noted that a plurality of ultrafiltration pipes 2 connected thereto are fixedly mounted on the ultrafiltration membrane group 12, which are used for functions such as the entry of liquid, the discharge of filtered liquid, and the discharge of waste liquid. Therefore, the ultrafiltration control system described in this embodiment can perform a unified monitoring function on these ultrafiltration pipes 2 through the cooperation of the liquid passing pipe 3 and the sealing connection structure 4 to ensure the safety and good sealing of the system body 1 during the application process.

[0041] Figure 1 - Fig.10 It is shown that a sealing ring is fixedly connected to the left end of the sealing threaded sleeve 42, and the sum of the thread engagement length of the sealing threaded sleeve 42 and the thickness of the sealing ring is 1.05 to 1.1 times the thread engagement length of the sealing threaded groove 21. The provision of the sealing ring can further improve the sealing protection effect of the sealing threaded sleeve 42 and the sealing threaded groove 21, further improve the sealing of the ultrafiltration pipeline 2 and the liquid passage 3, and also through the limitation of the engagement length size, can effectively achieve a certain pre-compression deformation effect on the sealing ring, so that the sealing ring can fill the gap between the sealing threaded sleeve 42 and the sealing threaded groove 21, and promote the sealing effect.

[0042] Figure 1 - Fig.10It is shown that an auxiliary disassembly ring is fixedly connected to the rear end of the sealing threaded sleeve 42, and the right end of the auxiliary disassembly ring extends to the outside of the sealing threaded groove 21. The auxiliary disassembly ring can facilitate the user to operate the sealing threaded sleeve 42, reduce the difficulty of disassembly and installation of the liquid pipe 3, and thus improve the maintenance efficiency when the seal is damaged, and reduce the downtime of the system body 1.

[0043] Figure 1 - Fig.10 It is shown that during the application of the system body 1, the technician first inputs various parameter data and control instructions about the ultrafiltration process to the instruction acquisition unit through the control buttons and touch display on the ultrafiltration controller 11, including but not limited to the working time, power and interval gap of the pump, the pressure difference and flow data at the inlet and outlet ends of the ultrafiltration membrane group 12, and the time of waste liquid discharge and other parameter data. Then the instruction acquisition unit transmits these instruction data to the ultrafiltration control processing unit, and the ultrafiltration control processing unit processes and acts on these data. After the technician starts the system body 1, the ultrafiltration control processing unit sends a control instruction to the ultrafiltration control unit according to the instruction parameters, so that the ultrafiltration control unit controls the various components in the system body 1 to perform corresponding actions, such as opening the pipeline valve through the pressure control system, and adjusting the flow and pressure difference data, starting the pump to draw the raw liquid into the ultrafiltration membrane group 12, and then after being processed by the ultrafiltration membrane group 12, the collection The ultrafiltration parameter acquisition unit can collect the operating status of these components while the components in the system body 1 perform corresponding actions, and then transmit the collected data to the ultrafiltration control processing unit, so that the ultrafiltration control processing unit can control the components in the system body 1 to generate ultrafiltration operations while also collecting and judging the operating status and instruction execution status of each component, so as to ensure the operating stability and safety of each component in the system body 1, and during the operation of the system body 1, the ultrafiltration control processing unit will transmit the control parameters and the operating status data of each component to the ultrafiltration data display unit, and the ultrafiltration data display unit will transmit the data to the touch block display on the ultrafiltration controller 11, and display the operating status and related data of the system body 1 to the technicians in real time through the touch display, so that the technicians can control and adjust the system body 1 as needed.

[0044] During the operation of the system body 1, the raw liquid enters the ultrafiltration membrane group 12 or the filtrate is discharged from the ultrafiltration membrane group 12, and is discharged through the corresponding ultrafiltration pipe 2. The pressure of the liquid flow will continuously impact the connection between the ultrafiltration pipe 2 and the liquid passage pipe 3. Then, when the ultrafiltration pipe 2 and the liquid passage pipe 3 are sealed due to internal or external factors, that is, the impact of the liquid flow and the sealing abnormality caused by external accidental pulling and other factors, part of the liquid will seep out through the connection gap between the sealing thread groove 21 and the adapter waist sleeve 41 and the sealing thread sleeve 42, causing the liquid absorption sensing sleeve 44 to absorb water. Then, after the liquid absorption sensing sleeve 44 is saturated with water, the moisture absorption conductive contact piece inside it will be triggered, and then the moisture absorption conductive signal The signal is transmitted to the leakage sensing unit, and the leakage sensing unit transmits the conduction data to the ultrafiltration control processing unit. After receiving the conduction data, the ultrafiltration control processing unit determines that there is a leakage abnormality in the connection between the ultrafiltration pipeline 2 and the liquid pipe 3 at this time, and then transmits the data to the touch block display through the ultrafiltration data display unit for display, and displays the abnormal data at this time to the technician. At the same time, the ultrafiltration control processing unit will also send an alarm instruction to the leakage alarm unit, so that the leakage alarm unit starts the alarm and sends an alarm reminder to the technician, reminding the technician to check and deal with the abnormality to avoid environmental pollution and safety problems caused by excessive liquid leakage, thereby effectively realizing the automatic control and real-time monitoring of the operating status of the system body 1 to ensure the safe operation of the system body 1.

[0045] Second implementation method:

[0046] Figure 1 - Fig.10As a further improvement of the present application, a sensing chamber 22 located on the left side of the sealing thread groove 21 is provided in the ultrafiltration pipeline 2, and a plurality of sealing sensing structures 5 evenly distributed along the circumferential direction are arranged in the sensing chamber 22, and the sealing sensing structure 5 includes a sensing trigger block 54 fixedly connected to the left inner wall of the sensing chamber 22, and a reset elastic member 55 sleeved on the outer end of the sensing trigger block 54 is fixedly connected to the left inner wall of the sensing chamber 22, and a retaining ring 52 is fixedly connected to the right end of the reset elastic member 55, and a sensing abutment block 53 matched with the sensing trigger block 54 is fixedly connected to the left end of the retaining ring 52, and a round-headed sliding column 51 is fixedly connected to the right end of the retaining ring 52, and the round-headed sliding column 51 extends into the sealing thread groove 21 and cooperates with the sealing thread sleeve 42, and the cooperation between the sensing abutment block 53 and the sensing trigger block 54 On the one hand, during the installation of the ultrafiltration pipeline 2 and the liquid passage pipe 3, auxiliary judgment can be made on the installation position and installation accuracy of the sealing connection structure 4, thereby effectively ensuring the sealing effect of the connection between the ultrafiltration pipeline 2 and the liquid passage pipe 3, reducing the problem of poor sealing caused by installation errors, and effectively realizing the automatic detection of the installation position of the sealing connection structure 4. On the other hand, during the application of the system body 1, the sealing connection structure 4 can be damaged by impact or the seal is damaged in the early stage of leakage, thereby effectively improving the timeliness of maintenance of the system body 1, and can play a role in predicting leakage, effectively avoiding the problem of shutdown maintenance of the system body 1 due to leakage, reducing economic losses, and promoting the economic benefits of the system body 1.

[0047] Figure 1 and Figure 2 It is shown that the input end of the ultrafiltration control processing unit is also connected to a sealing feedback unit, and the input end of the sealing feedback unit is connected to the signal of the induction trigger block 54. The setting of the sealing feedback unit can effectively realize the intelligent detection function of the system body 1 on the installation accuracy and application status of the liquid pipe 3, effectively promote the automation and intelligence of the system body 1, increase the functionality of the system body 1, improve the installation accuracy of the system body 1, and reduce the difficulty of installation and maintenance of the system body 1.

[0048] Figure 1 - Fig.10 It is shown that the reset elastic member 55 is in an extended state when not acted upon by external force. After the liquid passage tube 3 is disassembled, the reset elastic member 55 can actively drive the round-head slide column 51 to move toward the sealing thread groove 21, thereby promoting the separation of the sensing abutment block 53 and the sensing trigger block 54 under the linkage of the retaining ring 52, thereby ensuring the accuracy and effectiveness of the sealing detection in subsequent installation and application, and promoting the sensing sensitivity of the sealing feedback unit.

[0049] Figure 1 and Figure 2It is shown that multiple induction trigger blocks 54 are independently signal-connected to the sealing feedback unit, and the input end of the sealing feedback unit is also connected to the auxiliary positioning unit. The input end of the auxiliary positioning unit is signal-connected to the touch display and control button arranged at the front end of the ultrafiltration controller 11. The independent signal-connected induction trigger blocks 54 and the auxiliary positioning unit can assist the ultrafiltration control processing unit to timely determine the abnormal position or abnormal direction when damage and leakage signs appear between the sealing thread sleeve 42 and the sealing thread groove 21, so as to facilitate the user to process and judge the abnormal data, and then eliminate and analyze the cause of the abnormality, so as to promote the improvement or application improvement of the system body 1, thereby effectively promoting the development of the system body 1 and extending the service life of the system body 1.

[0050] Figure 1 and Figure 2 It is shown that the left end of the adapter waist sleeve 41 is embedded with a mounting contact block, the right end of the ultrafiltration pipeline 2 is embedded with a conducting block corresponding to the mounting contact block, the input end of the ultrafiltration control processing unit is also connected to the mounting position sensing unit, the input end of the mounting position sensing unit is connected with the mounting contact block signal, the setting of the mounting contact block and the mounting sensing unit can further improve the installation accuracy of the liquid passing tube 3, and through the digital coordination installation steps, it can ensure the installation sealing of the liquid passing tube 3 and the ultrafiltration pipeline 2 while reducing the installation damage caused by improper installation operation, further extending the service life of the ultrafiltration pipeline 2, the liquid passing tube 3 and the sealing connection structure 4, and ensuring the effectiveness of the seal.

[0051] Figure 1 - Fig.10 It is shown that when the technician needs to reinstall the liquid passage tube 3, the auxiliary disassembly ring is first used to drive the rotating sealing thread sleeve 42 so that it is screwed out of the sealing thread groove 21. In the process of the sealing thread sleeve 42 being continuously screwed out, the reset elastic member 55 produces an elastic reset effect, and the retaining ring 52 pushes the round head slide column 51 to move rightward, so that the sensing abutment block 53 and the sensing trigger block 54 are separated. At this time, the sealing feedback unit cannot receive the sensing signal transmitted by the sensing trigger block 54, and the ultrafiltration control processing unit can judge based on the sealing feedback unit not transmitting the sensing signal. At this time, the right end of the ultrafiltration pipe 2 is not connected or sealed, and a status prompt is sent to the touch display of the ultrafiltration controller 11 through the ultrafiltration data display unit, and the ultrafiltration control unit is turned off. While reminding the technician of the status of the ultrafiltration pipe 2 at this time, it also avoids the situation where the system body 1 is started due to misoperation by the technician, and avoids the problem of liquid leakage caused by abnormal startup. After the sealing threaded sleeve 42 is completely unscrewed, pull the sealing threaded sleeve 42 to the right end of the liquid passing tube 3, and then pull the liquid passing tube 3 out of the ultrafiltration pipe 2 to complete the disassembly of the liquid passing tube 3.

[0052] The technician reinstalls the new liquid-passing tube 3 by first inserting the liquid-passing tube 3 into the ultrafiltration pipeline 2. Then, when the left end of the adapter waist sleeve 41 abuts against the right end of the sealing thread groove 21, the technician slightly rotates the liquid-passing tube 3 to make the installation contact block contact with the conduction block, triggering the installation position sensing unit. The installation position sensing unit transmits the installation position arrival signal to the ultrafiltration control processing unit. The ultrafiltration control processing unit sends a signal to the touch display of the system body 1 through the ultrafiltration data display unit, so that the technician can observe the liquid-passing tube 3 and the adapter waist sleeve. 41 is installed in the right position, and then the position of the liquid pipe 3 and the adapter waist sleeve 41 is maintained at this time, and then the sealing thread sleeve 42 is pushed to move to the left, so that the squeezing and pushing ring 43 and the squeezing and pushing ring 43 move to the left on the adapter waist sleeve 41, and squeeze the liquid suction sensing sleeve 44, and then after the liquid suction sensing sleeve 44 moves to the right end portion of the sealing thread groove 21, the sealing thread sleeve 42 is rotated to make it continuously screwed into the sealing thread groove 21 through the thread engagement with the sealing thread groove 21, and the sealing thread sleeve 42 enters the sealing thread groove 21. After the sealing threaded sleeve 42 is fully screwed into the groove 21, the screwing in of the sealing threaded sleeve 42 will simultaneously produce an extrusion effect on the round-headed sliding column 51, so that the round-headed sliding column 51 produces a leftward pushing force on the retaining ring 52, thereby compressing the reset elastic member 55, and the sensing abutment block 53 is driven to continuously move toward the sensing trigger block 54. After the sealing threaded sleeve 42 is fully screwed in, the sealing ring at the front end of the sealing threaded sleeve 42 is squeezed to fill the gap, and then the round-headed sliding column 51 is fully squeezed, causing the sensing abutment block 53 and the sensing trigger block 54 to abut and contact, and the sealing feedback unit sends a sensing signal. At this time, the sealing feedback unidirectionally sends sealing feedback data to the ultrafiltration control processing unit. The ultrafiltration control processing unit determines that the liquid passage pipe 3 and the sealing connection structure 4 are installed at this time, and the ultrafiltration pipeline 2 and the liquid passage pipe 3 are in a good sealing state, and then displays the data on the touch display through the ultrafiltration data display unit. The technician can judge the data that the liquid passage pipe 3 is installed in place by observing the data, and then the ultrafiltration control processing unit turns on the ultrafiltration control unit, so that the system body 1 can be operated normally.

[0053] When the technician inputs the relevant control parameters to the instruction acquisition unit through the control buttons and contact block display on the ultrafiltration controller 11, the different position data of the sealing sensing structure 5 in the ultrafiltration pipeline 2 will be written to the auxiliary positioning unit. The auxiliary positioning unit transmits the received positioning data to the sealing feedback. When the sealing feedback unit receives the sensing signal transmitted by the sensing trigger block 54, it will match the sensing signal with the corresponding position, and then transmit it to the ultrafiltration control processing unit. When the connection of the liquid passage tube 3 in the ultrafiltration pipeline 2 is abnormally tilted due to liquid impact or external force pulling, that is, the sensing abutment block 53 on one side and the sensing trigger block 54 no longer have contact, the sealing feedback unit transmits the received sensing signal and the corresponding position data to the ultrafiltration control processing unit. The control processing unit processes and analyzes the data, and then determines the state of the liquid passage tube 3 at this time based on the position of the sealing sensing structure 5 that has not been triggered. Therefore, it can not only sense the sealing damage when the ultrafiltration pipeline 2 and the liquid passage tube 3 are sealed, that is, in the early stage of leakage, but also send a damage reminder to the touch display through the ultrafiltration data display unit, and activate the alarm through the leakage alarm unit to remind the technicians, so that the technicians can correct the position or perform maintenance on the liquid passage tube 3 in time to ensure its sealing function and avoid liquid leakage. The specific position display can also be used to provide direction prompts to the technicians, reduce the difficulty of maintenance or position correction for the technicians, provide them with effective data support, thereby improving the maintenance efficiency and ensuring the normal operation of the system body 1.

[0054] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
