Description

Technical Field

[0001] The invention relates to a filtering device, in particular to a biological experiment plant liquid filtering device applied in the separation field. Background Art

[0002] The biological experiment plant liquid filtration device is an instrument specially used for filtering plant liquid in biological experiments. It can be widely used to separate and purify various biologically active components from plant liquid. The biological experiment plant liquid filtration device mainly uses ultrafiltration technology to filter plant liquid. Specifically, it is a membrane separation technology based on molecular size, using a semi-permeable membrane with a specific pore size to separate large molecules and small molecules in the solution. In the treatment of plant liquid, the ultrafiltration membrane allows water and low molecular weight substances (such as salts, sugars, etc.) to pass through, while larger molecules (such as proteins, starches, polysaccharides, etc.) are retained, thereby achieving the purpose of separation and purification.

[0003] The structure of the biological experiment plant liquid filtration device mainly includes ultrafiltration membrane components, inlet and outlet water pipes, and filtration control systems. The core part of ultrafiltration technology uses asymmetric microporous structures and semipermeable membrane media to allow small molecular solutes and solvents to pass through the membrane pores under a certain pressure, thereby retaining large molecular solutes on one side of the membrane. As the automation guarantee of ultrafiltration technology, the filtration control system is mainly responsible for monitoring the operating status of the equipment, adjusting the inlet and outlet water flow and pressure, and performing automatic cleaning, backwashing and other operations. Through the coordinated work of these components, efficient filtration and purification of water quality can be achieved together.

[0004] During the application of the biological experiment plant liquid filtration device, the surface of the ultrafiltration membrane component will be contaminated and blocked during long-term application, so the ultrafiltration module will be cleaned through automatic cleaning and backwashing operations to ensure its functionality. However, during the cleaning operation of the ultrafiltration membrane component, since the internal membrane elements of the ultrafiltration membrane component are mainly composed of a plurality of hollow fiber tube membranes, there are small gaps between them, and the contact surface between the cleaning surface and the cleaning fluid remains constant, the cleaning effect is not high during the cleaning process and a long cleaning time is required, which will not only cause damage to the internal membrane elements, but also cause resource loss, making the biological experiment plant liquid filtration device not environmentally friendly. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to solve the problem of low cleaning efficiency and poor effect caused by small gaps between multiple hollow fiber tube membranes inside the ultrafiltration membrane assembly and the constant contact surface between the cleaning surface and the cleaning fluid during the automatic cleaning and backwashing operations of the biological experiment plant liquid filtration device.

[0006] In order to solve the above problems, the present invention provides a biological experiment plant liquid filtering device, comprising a filtering device body, a filtering controller fixedly installed at the front end of the filtering controller and a plurality of ultrafiltration modules arranged inside the filtering device body, ultrafiltration membrane group heads are fixedly installed at both upper and lower ends of the ultrafiltration module, a stabilizing sleeve is fixedly connected to the inner wall of the side of the ultrafiltration membrane group head away from the ultrafiltration module, a buckle sleeve inner ring located inside the stabilizing sleeve is slidably arranged on the inner wall of the side of the ultrafiltration membrane group head away from the ultrafiltration module, a plurality of cleaning dynamic components matched with the buckle sleeve inner ring are fixedly connected to the inner end of the stabilizing sleeve, a fiber tube buckle sleeve is fixedly connected to the inner end of the cleaning dynamic component, and a plurality of fiber tube membrane elements are fixedly connected between the upper and lower fiber tube buckle sleeves;

[0007] The filter controller is internally equipped with a cleaning dynamic auxiliary subsystem that cooperates with the filter control system. The cleaning dynamic auxiliary subsystem includes a cleaning dynamic processing unit. The input end of the cleaning dynamic processing unit is connected to a filtering instruction acquisition unit and a cleaning reset acquisition unit. The output end of the cleaning dynamic processing unit is connected to a cleaning dynamic control unit and a dynamic abnormality feedback unit.

[0008] The input end of the filtering instruction acquisition unit is connected to the filtering control system signal, the input end of the cleaning reset acquisition unit is connected to the cleaning dynamic component signal, the output end of the cleaning dynamic regulation unit is connected to the cleaning dynamic component signal, and the output end of the dynamic abnormality feedback unit is connected to the filtering control system signal.

[0009] In the above-mentioned biological experiment plant liquid filtration device, the dynamics of the fiber tube membrane element can be increased during the self-cleaning process of the ultrafiltration module, effectively improving the cleaning efficiency, promoting the cleaning effect, ensuring the effect and quality of the filter device body on plant liquid filtration, and can also effectively reduce the loss of cleaning resources, promote the environmental protection of the filter device body, and reduce the application cost of the filter device body.

[0010] As a supplement to the present application, the cleaning dynamic component includes a cleaning position sleeve fixedly connected to the inner end of the stabilizing sleeve, and the two inner walls of the cleaning position sleeve perpendicular to the radial direction are fixedly connected to matching oscillation electromagnetic blocks, and an elastic isolation piece is fixedly connected between the two oscillation electromagnetic blocks, and the output end of the cleaning dynamic control unit is connected to the oscillation electromagnetic block signal.

[0011] As a supplement to the present application, the two oscillating electromagnetic blocks are fixedly connected to matching sensing column heads at one end thereof, and the input end of the cleaning reset acquisition unit is connected to the sensing column head signal.

[0012] As a further improvement of the present application, the output end of the cleaning dynamic processing unit is also connected to a filtering stabilization control unit, the output end of the filtering stabilization control unit is connected to the oscillation electromagnetic block signal, and the instruction priority of the filtering stabilization control unit is higher than that of the cleaning dynamic control unit.

[0013] As a further improvement of the present application, the output end of the cleaning dynamic processing unit is also connected to a forced reset control unit, the output end of the forced reset control unit is connected to the oscillation electromagnetic block signal, and the instruction priority of the cleaning dynamic control unit is higher than the instruction priority of the forced reset control unit.

[0014] As a further improvement of the present application, the inner wall of the ultrafiltration membrane group head away from the inner end of the ultrafiltration module is provided with multiple slide grooves with corresponding angles to the cleaning dynamic components, and the lower end of the inner ring of the buckle sleeve is fixed with a limiting column that cooperates with the slide groove, and the width of the slide groove is 2-3 times the diameter of the limiting column.

[0015] As another improvement of the present application, the number of the multiple cleaning dynamic components is X, and the value expression of X is {x|x=2n, n∈{2,3,4,5,6}}.

[0016] As another improvement supplement of the present application, when the cleaning dynamic regulation unit is in effect, the cleaning dynamic components are independently controlled, and the cleaning dynamic components at the upper and lower ends are regulated accordingly, that is, when the single cleaning dynamic component located at the upper end is regulated to produce an elongation deformation, the same elongation deformation regulation is performed on the single cleaning dynamic component symmetrically located directly below the single cleaning dynamic component at the upper end, thereby realizing the inclination regulation of the fiber tube buckle sleeve, and then the cleaning dynamic regulation unit regulates and coordinates the single cleaning dynamic components in sequence along the circumferential direction to realize the cleaning dynamic action of the fiber tube buckle sleeve.

[0017] In summary, through the cooperation of the cleaning dynamic component, the inner ring of the buckle sleeve and the cleaning dynamic auxiliary subsystem, the dynamics of the fiber tube membrane element can be increased during the self-cleaning process of the ultrafiltration module. By changing the positions of the upper and lower ends of the fiber tube membrane element, the position of its cleaning surface can be adjusted, the contact area between the cleaning surface of the fiber tube membrane element and the cleaning fluid is increased, and the cleaning angle is changed.

DETAILED DESCRIPTION

[0033] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0034] The first implementation method:

[0035] Figure 1 - Fig.13 A biological experiment plant liquid filtering device is shown, comprising a filtering device body 1, a filtering controller 11 fixedly installed at the front end of the filtering controller 11, and a plurality of ultrafiltration modules 2 arranged inside the filtering device body 1, wherein ultrafiltration membrane group heads 21 are fixedly installed at both upper and lower ends of the ultrafiltration module 2, a stabilizing sleeve 5 is fixedly connected to the inner wall of the ultrafiltration membrane group head 21 away from the ultrafiltration module 2, a buckle sleeve inner ring 4 located inside the stabilizing sleeve 5 is slidably provided on the inner wall of the ultrafiltration membrane group head 21 away from the ultrafiltration module 2, a plurality of cleaning dynamic components 3 matched with the buckle sleeve inner ring 4 are fixedly connected to the inner end of the stabilizing sleeve 5, a fiber tube buckle sleeve 23 is fixedly connected to the inner end of the cleaning dynamic component 3, and the fiber tube buckle sleeve 23 is made of elastic material, and can release the tilting margin when the cleaning dynamic component 3 drives the fiber tube buckle sleeve 23 to produce a dynamic tilting action, thereby ensuring the tilting action and reducing the tensile damage to the fiber tube buckle sleeve 23, and a plurality of fiber tube membrane elements 22 are fixedly connected between the upper and lower fiber tube buckle sleeves 23;

[0036] The filter controller 11 is internally equipped with a cleaning dynamic auxiliary subsystem that cooperates with the filter control system. The cleaning dynamic auxiliary subsystem includes a cleaning dynamic processing unit. The input end of the cleaning dynamic processing unit is connected to a filtering instruction acquisition unit and a cleaning reset acquisition unit. The output end of the cleaning dynamic processing unit is connected to a cleaning dynamic regulation unit and a dynamic abnormality feedback unit.

[0037] The input end of the filtering instruction acquisition unit is connected to the filtering control system signal, the input end of the cleaning reset acquisition unit is connected to the cleaning dynamic component 3 signal, the output end of the cleaning dynamic regulation unit is connected to the cleaning dynamic component 3 signal, and the output end of the dynamic abnormality feedback unit is connected to the filtering control system signal. Through the cooperation of the cleaning dynamic component 3, the buckle inner ring 4 and the cleaning dynamic auxiliary subsystem, the dynamics of the fiber tube membrane element 22 can be increased during the self-cleaning process of the ultrafiltration module 2. By changing the upper and lower end positions of the fiber tube membrane element 22, the position of its cleaning surface is adjusted, the contact area between the cleaning surface of the fiber tube membrane element 22 and the cleaning fluid is increased, and the cleaning angle is changed, thereby effectively improving the cleaning efficiency and promoting the cleaning effect, protecting the fiber tube membrane element 22 inside the ultrafiltration module 2, and promoting the application life and application stability of the ultrafiltration module 2, ensuring the effect and quality of the filter body 1 on plant liquid filtration, and effectively reducing the loss of cleaning resources, promoting the environmental protection of the filter body 1, and reducing the application cost of the filter body 1.

[0038] Figure 8 - Fig.13 The cleaning dynamic component 3 is shown to include a cleaning position sleeve 31 fixedly connected to the inner end of the stabilizing sleeve 5, and the two inner walls of the cleaning position sleeve 31 perpendicular to the radial direction are fixedly connected with matching oscillation electromagnetic blocks 32, and an elastic isolation piece 33 is fixedly connected between the two oscillation electromagnetic blocks 32. The output end of the cleaning dynamic regulation unit is connected to the oscillation electromagnetic block 32 signal. The setting of the oscillation electromagnetic block 32 and the cleaning dynamic regulation unit can realize the automatic control of the cleaning dynamic adjustment, which can effectively improve the cleaning effect and promote the cleaning effectiveness. While ensuring the subsequent filtering effect of the filter body 1 on the plant liquid, it can also reduce the adjustment damage in the cleaning dynamic process through the effect of high-precision regulation, thereby ensuring the functional effectiveness of the fiber tube membrane element 22.

[0039] Figure 8 - Fig.13 It is shown that two oscillating electromagnetic blocks 32 are fixedly connected to the matching induction column head 6 at one end, and the input end of the cleaning reset collection unit is connected to the signal of the induction column head 6. The setting of the induction column head 6 and the cleaning reset collection unit can effectively judge and collect the state of the cleaning position sleeve 31 acting on the inner ring 4 of the buckle sleeve, and can effectively realize the role of corresponding regulation in sequence during the cleaning process, thereby ensuring the effectiveness of the dynamic cleaning effect.

[0040] Figure 2 It is shown that the output end of the cleaning dynamic processing unit is also connected to a filtering stabilization regulation unit, and the output end of the filtering stabilization regulation unit is connected to the signal of the oscillation electromagnetic block 32, and the instruction priority of the filtering stabilization regulation unit is higher than that of the cleaning dynamic regulation unit. The cooperation between the filtering stabilization regulation unit and the oscillation electromagnetic block 32 further increases the effect of the cleaning dynamic component 3. In the process of the filtering device body 1 filtering the plant liquid, the inner ring 4 of the buckle sleeve can effectively realize the stable clamping effect of the fiber tube membrane element 22, thereby ensuring the filtering position of the fiber tube membrane element 22 and the effectiveness of the fiber tube membrane element 22 in filtering the plant liquid.

[0041] Figure 1 - Fig.13 It is shown that the inner wall of the ultrafiltration membrane group head 21 away from the inner end of the ultrafiltration module 2 is provided with multiple slide grooves with corresponding angles to the cleaning dynamic component 3, and the lower end of the buckle inner ring 4 is fixed with a limiting column that cooperates with the slide groove, and the width of the slide groove is 2-3 times the diameter of the limiting column. The setting of the slide groove and the limiting column can realize the sliding effect of the buckle inner ring 4, and realize the movement of the fiber tube membrane element 22 through the fiber tube buckle 23. At the same time, it can also limit the width of the slide groove, so that the buckle inner ring 4 can produce angular movement, reduce the restriction effect between the slide grooves, and further promote the dynamic effect of the fiber tube membrane element 22 during the cleaning process.

[0042] Figure 1-Figure 13It is shown that the number of the plurality of cleaning dynamic components 3 is X, and the value expression of X is {x|x=2n, n∈{2,3,4,5,6}}, Figure 1-Figure 13 It is shown that when the cleaning dynamic regulation unit is in action, the cleaning dynamic component 3 is independently controlled, and the cleaning dynamic components 3 at the upper and lower ends are regulated accordingly, that is, when the single cleaning dynamic component 3 located at the upper end is regulated to produce an elongation deformation, the single cleaning dynamic component 3 located at a symmetrical position directly below the single cleaning dynamic component 3 at the upper end is subjected to the same elongation deformation regulation, thereby realizing the tilt regulation effect on the fiber tube buckle sleeve 23, and then the cleaning dynamic regulation unit regulates and coordinates the single cleaning dynamic components 3 in sequence along the circumferential direction to realize the cleaning dynamic effect of the fiber tube buckle sleeve 23. The even number of cleaning dynamic components 3 can effectively achieve the effect of their paired action, which can not only reduce the control difficulty of the cleaning dynamic auxiliary subsystem, but also enable the fiber tube membrane element 22 to achieve the maximum effect of its mobility during the cleaning process of the ultrafiltration module 2, thereby further improving the cleaning effect and efficiency, and ensuring its subsequent effectiveness in filtration of plant liquid.

[0043] Figure 1 - Fig.13 It is shown that during the application of the filter device body 1, the filter control system controls the filter device body 1 to perform filtering work for a period of time, and then controls the filter device body 1 to perform automatic cleaning and backwashing operations, and introduces a clean fluid into the ultrafiltration module 2 to clean the ultrafiltration module 2 and remove the substances adhering to the outer wall surface of the fiber tube membrane element 22. When the filter control system generates a cleaning instruction, the filter instruction acquisition unit can collect the data and then transmit it to the cleaning dynamic processing unit. The cleaning dynamic processing unit transmits the cleaning dynamic instruction data to the cleaning dynamic regulation unit, so that the cleaning dynamic regulation unit first performs cleaning on all The oscillating electromagnetic block 32 in the dynamic component 3 sends out a reset command, cutting off the current in the oscillating electromagnetic block 32, causing the elastic isolation piece 33 to produce a contraction effect of elastic reset, which can drive the two oscillating electromagnetic blocks 32 located in the same cleaning position sleeve 31 to produce a close effect, and drive the cleaning position sleeve 31 to produce a contraction effect away from the buckle sleeve inner ring 4. Under the contraction effect of the elastic isolation piece 33, the induction column head 6 located on the oscillating electromagnetic block 32 will be driven to produce a contact triggering effect, and then the induction column head 6 sends a trigger induction signal to the cleaning reset acquisition unit, and the cleaning reset acquisition unit transmits the trigger data of multiple induction column heads 6 to the cleaning dynamic processing unit;

[0044] After determining that all the induction column heads 6 in a single ultrafiltration module 2 have completed the triggering of the induction, the cleaning dynamic processing unit again sends a cleaning dynamic instruction to the cleaning dynamic regulation unit, so that the cleaning dynamic regulation unit performs a pair of individual control on the cleaning dynamic components 3 in the same ultrafiltration module 2, and performs corresponding joint control on the cleaning dynamic components 3 located at the upper and lower ends, that is, the single cleaning dynamic component 3 at the upper end, and the single cleaning dynamic component 3 symmetrically located to the single cleaning dynamic component 3 located directly below the single cleaning dynamic component 3 at the upper end, and passes current into the two oscillating electromagnetic blocks 32 inside thereof, so that the two oscillating electromagnetic blocks 32 produce repulsive magnetic forces, and at the same time, the two oscillating electromagnetic blocks 32 are repelled from each other. Under the repulsive effect, the oscillating electromagnetic block 32 drives the cleaning position sleeve 31 to elongate and deform, and then pushes the inner ring 4 of the buckle sleeve, so that the inner ring 4 of the buckle sleeve drives the fiber tube membrane element 22 to tilt through the fiber tube buckle sleeve 23, thereby changing the contact area and release angle between the cleaning surface of the fiber tube membrane element 22 and the cleaning fluid, thereby promoting the cleaning effect. After the elongation instruction is completed, the cleaning dynamic control unit controls the above-mentioned single cleaning dynamic components 3 located at the upper and lower ends to produce a reset effect, that is, disconnects the current of the oscillating electromagnetic block 32 in the cleaning dynamic component 3, so that the elastic isolation piece 33 produces an elastic reset effect, driving the oscillating electromagnetic block 32 to act on the cleaning position The sleeve 31 produces a contraction effect, releasing the pushing effect on the inner ring 4 of the buckle sleeve, and then the cleaning dynamic control unit controls the single cleaning dynamic component 3 located at the symmetrical position of the single cleaning dynamic component 3 at the upper and lower ends again, so that the oscillating electromagnetic block 32 inside it produces a repulsive electromagnetic force, and the current passed into the single oscillating electromagnetic block 32 stacked in a symmetrical position at both ends is smaller than the current of the single oscillating electromagnetic block 32 at the upper and lower ends. Then, at this time, the oscillating electromagnetic block 32 drives the cleaning position sleeve 31 to produce a pushing effect, and can drive the inner ring 4 of the buckle sleeve to produce a reset action through the cleaning position sleeve 31, so that the inner ring 4 of the buckle sleeve drives the fiber tube buckle sleeve 23 The fiber tube membrane element 22 is driven to move to the central position, and then the cleaning dynamic control unit controls the oscillating electromagnetic block 32 in the single cleaning dynamic component 3 stacked at the upper and lower ends to cut off the current, so that the oscillating electromagnetic block 32 loses its magnetism, and the elastic isolation member 33 produces a contraction effect to restore the deformation, driving the cleaning position sleeve 31 to produce a reset effect, and then completing a single regulation of the cleaning dynamics, and then the cleaning dynamic control unit sequentially controls the cleaning dynamic component 3 in a single corresponding manner along the circumferential direction, so as to achieve the tilting control effect of the fiber tube membrane element 22 at different angles during the cleaning process of the ultrafiltration module 2, thereby realizing the cleaning dynamic effect of the fiber tube membrane element 22;

[0045] In the process of the cleaning dynamic processing unit controlling the action of the cleaning dynamic regulation unit, the overall reset regulation of the cleaning dynamic component 3 and the reset regulation of the cleaning dynamic component 3 in the subsequent single control process, the sensing column head 6 will transmit the trigger sensing data of its reset regulation to the cleaning reset acquisition unit, and the cleaning reset acquisition unit will continue to transmit its trigger sensing data to the cleaning dynamic processing unit. The cleaning dynamic processing unit determines whether the cleaning position sleeve 31 produces a reset contraction effect under the elastic recovery of the elastic isolation member 33 according to whether the sensing column head 6 generates trigger sensing data. When it is determined that the reset of the cleaning position sleeve 31 is normal according to the trigger sensing data, the cleaning dynamic processing unit maintains the cleaning dynamic The cleaning dynamic control function of the control unit, when it is judged that the cleaning position sleeve 31 is reset abnormally according to the trigger sensing data, the cleaning dynamic processing unit will transmit the abnormal data to the dynamic abnormal feedback unit, so that the filtration control system will send a cleaning abnormality alarm to the laboratory personnel through its data output end, and the cleaning dynamic processing unit will also send a stop command to the cleaning dynamic control unit to avoid continuous dynamic control in the reset abnormal state to cause damage to the buckle inner ring 4, the fiber tube buckle sleeve 23, the fiber tube membrane element 22 and the cleaning dynamic component 3, thereby avoiding the spread of abnormal accidents, effectively achieving the effect of protecting the ultrafiltration module 2, reducing the abnormal maintenance cost, and ensuring the filtration quality of the ultrafiltration module 2.

[0046] When the filtration control system controls the filtration device body 1 to filter the plant liquid, the filtration instruction acquisition unit will receive the filtration control instruction, and then transmit the filtration instruction to the cleaning dynamic processing unit, and the cleaning dynamic processing unit transmits the control instruction data to the filtration stability control unit, so that the filtration stability control unit simultaneously inputs current into multiple cleaning dynamic components 3, so that the two oscillating electromagnetic blocks 32 located in the same cleaning position sleeve 31 produce repulsive electromagnetic effects, driving the cleaning position sleeve 31 to produce elongation deformation, and at the same time firmly clamping the inner ring 4 of the buckle sleeve, and then the fiber tube buckle sleeve 23 is used to fix the position of the fiber tube membrane element 22, thereby ensuring the stability of the fiber tube membrane element 22 during filtration. While ensuring the filtration effect, it can also effectively reduce the damage of the fiber tube membrane element 22, ensure the durability of the fiber tube membrane element 22, and reduce laboratory costs.

[0047] Second implementation method:

[0048] Figure 1 - Fig.13A biological experimental plant liquid filtering device is shown, and the output end of the cleaning dynamic processing unit is also connected to a forced reset control unit, and the output end of the forced reset control unit is connected to the oscillation electromagnetic block 32 signal, and the instruction priority of the cleaning dynamic control unit is higher than the instruction priority of the forced reset control unit. The setting of the forced reset control unit and the oscillation electromagnetic block 32 can ensure the effectiveness and continuity of the cleaning dynamics by regulating the oscillation electromagnetic block 32 when an abnormal triggering of the induction column head 6 occurs during the cleaning process. Avoid the movement of the inner ring 4 of the buckle sleeve being stuck due to the reset abnormality during the cleaning process.

[0049] Figure 1 - Fig.13 It is shown that when the cleaning dynamic processing unit determines that the cleaning position sleeve 31 is abnormally reset according to the trigger sensing data, the cleaning dynamic processing unit sends an abnormal feedback to the filtration control system through the dynamic abnormal feedback unit, and stops the cleaning dynamic control function of the cleaning dynamic control unit. At the same time, it also sends a forced reset instruction to the forced reset control unit, and transmits the data of the cleaning dynamic component 3 with reset abnormality to the pre-reset control unit, so that the forced reset control unit can independently control the cleaning dynamic component 3 with reset abnormality, input current into it, so that the two oscillating electromagnetic blocks 32 inside it produce an electromagnetic effect of mutual attraction, and then drive the cleaning position sleeve 31 to move. The sleeve 31 produces a contraction effect, so that the induction column head 6 located at the end close to the two oscillation electromagnetic blocks 32 can be driven to contact, and transmit the trigger induction to the cleaning reset acquisition unit. After receiving the trigger induction data transmitted by the cleaning reset acquisition unit, the cleaning dynamic processing unit restores the cleaning dynamic effect of the cleaning dynamic control unit to complete the auxiliary role of this cleaning dynamics and ensure the cleaning effect and cleaning efficiency. Then the cleaning dynamic processing unit outputs the data about this reset abnormality to the filtration control system through the dynamic abnormality feedback unit, so that laboratory personnel can promptly report and maintain the filter device body 1 to avoid damage from subsequent continuous use.

[0050] 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.
