Description

Technical Field

[0001] This invention relates to the field of analytical testing technology, and in particular to a pressure filtration system and a pressure filtration method. Background Technology

[0002] In pharmaceutical synthesis experiments, insoluble substances in the reaction solution need to be filtered to obtain a clear solution for analysis and other subsequent pharmaceutical synthesis processes. In existing technologies, a common method involves manually drawing the reaction solution from a test tube using a syringe, attaching a needle-type filter head to the syringe head, and filtering the insoluble substances by pressing down the syringe piston. This method is not only inefficient and complex to operate manually, but also prone to contamination of the operator's hands during the attachment of the needle-type filter head. Multiple sample transfers during the operation can also introduce experimental errors. Furthermore, the entire process requires highly skilled personnel, is unsuitable for high-intensity work, and cannot be integrated with subsequent automated synthesis steps, making it unsuitable for automation.

It solves the problem of low manual production efficiency, reduces filter press costs, improves filter press efficiency, and avoids hand contamination for test personnel, meeting the requirements of high-intensity operations. The decentralized flow of multiple modules working collaboratively shortens the spatial distance between each operation step in the filter press process, reducing transportation and waiting time between each operation step, making the flow between different operation steps more convenient, significantly improving the working efficiency of the filter press process, and simultaneously meeting the requirements of high-throughput experimental processing.

[0053] In one specific implementation, see Figure 1 The filter press system includes:

[0054] The filter press bottle assembly transfer module 11 has a filter pressing position 12 at one end in the Y-axis direction. The filter press bottle assembly transfer module 11 is used to drive the filter press bottle assembly carrier 13 to move in the Y-axis direction. The filter press bottle assembly carrier 13 is used to load the filter press bottle assembly, which includes a first filter press bottle 14 and a second filter press bottle 15. The first filter press bottle 14 and the second filter press bottle 15 are connected by a filter pressing membrane. Specifically, the filter press bottle assembly transfer module 11 can be a synchronous belt module, and can be driven in various ways and combinations. It is not limited to a synchronous belt module, but can also be driven by a cylinder, electric cylinder, or lead screw module.

[0055] Among them, see Figure 3 The filter press position 12 is located near the end of one end of the filter press bottle group transfer module 11. First, the second filter press bottle 15 is loaded into the filter press bottle group carrier 13. Then, the filter press bottle group transfer module 11 moves the filter press bottle group carrier 13 to the filter press position 12. The filter press transfer module 31 clamps the first filter press bottle 14 and completes the filter press at the filter press position 12.

[0056] In one specific implementation, see [link to implementation details]. Figure 7 The first filter press flask 14 can be an inner filter press flask, and the second filter press flask 15 is an outer filter press flask, with the inner filter press flask nested inside the outer filter press flask. Specifically, the bottom of the first filter press flask 14 has a first support portion for placing the filter press membrane, and a reinforcing rib is provided at the connection between the filter press membrane and the first filter press flask. The filter press membrane does not directly contact the first support portion. Placing the filter press membrane on the first support portion improves the accuracy of the filter press membrane's position during fixing, ensuring the precision of the filtration process. The bottom of the second filter press flask 15 is sealed. In this embodiment, the second filter press flask 15 contains the reaction solution, and the first filter press flask 14 is pressed into the second filter press flask 15, with the reaction solution entering the first filter press flask 14 through the filter press membrane. In another specific embodiment, the bottom of the first filter press flask 14 is sealed with a support membrane, and the second filter press flask 15 has a second support portion for placing the filter press membrane located away from the bottom. In this embodiment, the first filter flask 14 contains the reaction solution, and the first filter flask 14 is pressed into the second filter flask 15. The reaction solution enters the second filter flask 15 through a filter membrane. The filter membrane is a one-way filter membrane, which can allow the reaction solution in the first filter flask 14 to flow to the second filter flask 15, or allow the reaction solution in the second filter flask 15 to flow to the first filter flask 14. The two embodiments can use one-way filter membranes with different directions. The material of the one-way filter membrane can be selected according to the characteristics of different samples; for example, it can be polytetrafluoroethylene or polyamide.

[0057] In one specific implementation, see [reference] Figure 2The filter press flask carrier 13 includes a first filter press flask carrier and a second filter press flask carrier. There are at least two sets of filter press flask transfer modules 11. The first and second filter press flask carriers can be mounted on the same filter press flask transfer module 11 or on different filter press flask transfer modules 11. The first and second filter press flask carriers are divided into multiple receiving cavities. The outer contour of each cavity is slightly larger than the outer diameter of the first filter press flask 14 and the second filter press flask 15. Preferably, the shape of the receiving cavity is circular or square, facilitating the placement of the first filter press flask 14 and the second filter press flask 15 into the receiving cavity, making the first filter press flask 14 and the second filter press flask 15 more stable and less prone to tipping over.

[0058] The pipetting module 21 is used to move the pipetting assembly 22 containing the reaction solution in a first preset direction, which includes the X-axis and Y-axis directions. When the pipetting assembly 22 moves above the filter press flask assembly, the controller controls the pipetting assembly 22 to inject the reaction solution into the target filter press flask; the target filter press flask is either the first filter press flask or the second filter press flask. Specifically, when the bottom of the first filter press flask 14 is provided with a filter membrane, the pipetting assembly 22 injects the reaction solution into the second filter press flask 15; when the bottom of the first filter press flask 14 is provided with a support membrane, ... When the filter membrane is installed at the position opposite to the bottom of the second filter flask 15, the liquid transfer assembly 22 injects the reaction liquid into the first filter flask 14. The filter flask group transfer module 11 includes a first motor and a first synchronous belt. The filter flask group carrier 13 is placed on the first synchronous belt. The first motor drives the first synchronous belt to move. The filter flask group carrier 13 carries the second filter flask 15, so that the filter flask group carrier 13 placed on the first synchronous belt moves to the filter position 12, thereby moving the second filter flask 15 carried in the filter flask group carrier 13 to the filter position 12.

[0059] The pipetting assembly 22 is controlled by a controller to inject the reaction solution into the target filter press flask. This controller serves as the central control unit for the entire filter press system, issuing timely operating commands to the corresponding modules to achieve coordinated operation. For example, the controller can be one or more of a PLC, a microcomputer, or computer control software. The pipetting assembly 22 includes a pipette and a tip connected to the pipette. This tip, also called a pipette tip or a liquid aspirator, is a laboratory pipette tip, a consumable item, and can store a certain volume of liquid. The tip is placed in the tip compartment. The pipette tip has a mating part that mates with the tip. When the pipette moves to the tip compartment, it provides a downward force to connect with the tip through the mating part. After the tip is installed on the pipette, the pipette provides suction to draw the reaction solution into the tip for storage. Then, the pipetting module 21 moves the pipetting assembly 22 containing the reaction solution to the target filter flask. The pipette dispenses the solution, and the tip injects the stored reaction solution into the target filter flask, completing the aspiration and dispensing operation. The number of pipetting assemblies can be multiple, for example, three, thus corresponding to three solutions. This allows for simultaneous pipetting operations with different solutions, meeting high throughput requirements and enabling batch pipetting operations. The pipette can be replaced by a syringe pump or a peristaltic pump.

[0060] In other embodiments, the aforementioned first preset direction may include the X-axis, Y-axis, and Z-axis directions. For example, after the pipetting module 21 moves the pipetting assembly 22 containing the reaction solution along the X-axis and Y-axis to the target filter press flask, the pipetting module 21 can use the pipetting assembly 22 controller to move the tip along the Z-axis to near the mouth of the target filter press flask, thereby completing the liquid aspiration and dispensing operation. In this application, the X-axis, Y-axis, and Z-axis directions are perpendicular to each other.

[0061] The pressure filtration transfer module 31 is used to drive the first clamping device 32 to move in a second preset direction to clamp the first pressure filtration bottle 14 and move it to the pressure filtration position 12. The second preset direction includes the X-axis direction and the Z-axis direction. It cooperates with the second pressure filtration bottle 15 that has moved to the pressure filtration position 12. The first pressure filtration bottle 14 applies pressure to the second pressure filtration bottle 15 so that the reaction liquid in the target pressure filtration bottle is filtered through the pressure filtration membrane. Specifically, when the bottom of the first pressure filtration bottle 14 is provided with a pressure filtration membrane, the first pressure filtration bottle 14 applies pressure to the second pressure filtration bottle 15 so that the reaction liquid in the second pressure filtration bottle 15 is filtered through the pressure filtration membrane and enters the first pressure filtration bottle 14. When the bottom of the first pressure filtration bottle 14 is provided with a support membrane, and the second pressure filtration bottle 15 is provided with a pressure filtration membrane at a position opposite to the bottom, the first pressure filtration bottle 14 applies pressure to the second pressure filtration bottle 15 so that the reaction liquid in the first pressure filtration bottle 14 is filtered through the pressure filtration membrane and enters the second pressure filtration bottle 15.

[0062] In one specific embodiment, the filtration system operates as follows: the pipetting module 21 moves the pipetting assembly 22 containing the reaction solution above the filtration flask assembly; the controller controls the pipetting assembly 22 to inject the reaction solution into the second filtration flask 15; the filtration flask assembly carrier 13 carries the second filtration flask 15 containing the injected reaction solution; the filtration flask assembly transfer module 11 moves the filtration flask assembly carrier 13 to the filtration position 12; the filtration transfer module 31 drives the first clamping device 32 to clamp the first filtration flask 14 and move it to the filtration position 12, cooperating with the second filtration flask 15 located at the filtration position 12; pressure is applied to the second filtration flask 15 through the first filtration flask 14, causing the reaction solution in the second filtration flask 15 to pass through the filtration membrane into the first filtration flask 14, thus completing the filtration. In another specific embodiment, the filtration system operates as follows: the pipetting module 21 moves the pipetting assembly 22, containing the reaction solution, above the filtration flask assembly; the controller controls the pipetting assembly 22 to inject the reaction solution into the first filtration flask 14; the filtration flask assembly carrier 13 carries the second filtration flask 15; the filtration flask assembly transfer module 11 moves the filtration flask assembly carrier 13 to the filtration position 12; the filtration transfer module 31 drives the first clamping device 32 to clamp the first filtration flask 14 and move it to the filtration position 12, cooperating with the second filtration flask 15 located at the filtration position 12; pressure is applied from the first filtration flask 14 to the second filtration flask 15, causing the reaction solution in the first filtration flask 14 to pass through the filtration membrane into the second filtration flask 15, completing the filtration. This application is not limited to the above-described order of operations; that is, those skilled in the art can also choose a suitable order of judgment or perform several operations and steps simultaneously as needed, and this application does not impose any restrictions on this. This filter press system achieves automated connection between multiple filter press processes by setting up multi-directional transfer modules, thus realizing automated filter press. It solves the problems of low manual production efficiency, reduces filter press costs, improves filter press efficiency, and avoids hand contamination for test personnel, meeting the requirements of high-intensity operations. The decentralized flow of multiple modules working together shortens the spatial distance between each operation step in the filter press process, reduces transportation and waiting time between each operation step, and makes the flow between different operation steps more convenient. It can significantly improve the working efficiency of the filter press process and simultaneously meet the requirements of high-throughput experimental processing.

[0063] In one specific implementation, see Figure 10 and Figure 11The first gripping device 32 includes a first gripper 321 and a first gripper finger 322. The first gripper 321 can be an electric gripper or a pneumatic gripper. The first gripper finger 322 is mounted on the first gripper 321. The first gripper 321 controls the opening and closing of the first gripper finger 322. The first gripper finger is L-shaped and there are at least two of them. The first gripper fingers 322, which are arranged opposite to each other, can be configured to be able to approach each other to grip the first filter bottle 14 or the second filter bottle 15, and to be able to move away from each other to release the first filter bottle 14 or the second filter bottle 15. Specifically, the first clamping finger 322 includes a mounting plate and a clamping plate connected to the mounting plate. The shorter, outwardly protruding side of the first clamping finger 322 is the mounting plate, and a filter pressing portion is formed at the end of the clamping plate opposite to the mounting plate. This filter pressing portion can be, for example, a part of a spatial structure that defines a space for clamping the first filter press bottle 14 or the second filter press bottle 15 and pressing the first filter press bottle 14 into the second filter press bottle 15, such as a groove, cavity, blind hole, or other structure. In some embodiments, the filter pressing portion can be a groove, which includes a pressure-bearing surface 3221 and a support surface 3222. The support surface 3222 is used to clamp the first filter press bottle 14. The two grooves cooperate to form a cavity structure to clamp the first filter press bottle 14. Preferably, the cavity structure is polygonal in shape to ensure coaxiality. The pressure-bearing surface 3221 is used to press the first filter press bottle 14 into the second filter press bottle 15 to withstand axial pressure. This makes the clamping more stable and balanced, and less prone to tilting.

[0064] In one specific implementation, see Figure 1 , 2 The filter press system also includes an analysis disc transfer module 16, which is used to drive the analysis disc 17 to move in the Y-axis direction. The analysis disc transfer module 16 and the filter press bottle group transfer module 11 are arranged parallel to the Y-axis and adjacent to each other.

[0065] The end of the analysis tray transfer module 16 near the filter press position 12 is the filter press bottle group placement position 18.

[0066] The analysis disc transfer module 16 can be a synchronous belt module, and can be driven in various ways and combinations, not limited to synchronous belt modules. It can also be driven by cylinders, electric cylinders, or lead screw modules. Preferably, the analysis disc transfer module 16 includes a second motor and a second synchronous belt. The analysis disc 17 is placed on the second synchronous belt, and the second motor drives the second synchronous belt to move along the Y-axis, thereby moving the analysis disc 17 located on the second synchronous belt. The analysis disc 17 is divided into several receiving cavities for loading filter press bottle groups. The analysis disc transfer module 16 drives the analysis disc 17 loaded with filter press bottle groups to move. The outer contour of the receiving cavity is slightly larger than the outer diameter of the second filter press bottle 15. Preferably, the receiving cavity is circular or square, which facilitates the placement of the filter press bottle group into the receiving cavity, making the filter press bottle group more stable and less prone to tipping over.

[0067] In one specific implementation, see Figure 6 The filter press system also includes an analytical disc discharge assembly 4;

[0068] The analysis tray discharge assembly 4 includes an analysis tray Y-axis transfer module 41, an analysis tray Z-axis transfer module 42, and a second clamping device 43. The second clamping device 43 is disposed on the analysis tray Z-axis transfer module 42. Specifically, the analysis tray Z-axis transfer module 42 and the second clamping device 43 are arranged parallel to each other along the Z-axis direction.

[0069] The analysis tray transfer module 16 drives the analysis tray 17 to the filter press flask group placement position 18; preferably, the filter press flask group placement position 18 and the filter press position 12 are coaxially arranged along the X-axis, which facilitates the filter press transfer module to transfer the filter press flask group into the analysis tray.

[0070] The filter press transfer module 31 moves the filter press bottle group to the filter press bottle group placement position 18 and places the filter press bottle group on the analysis tray 17;

[0071] The Y-axis transfer module 41 and the Z-axis transfer module 42 of the analysis tray are linked to move the second clamping device 43 to the filter press bottle assembly placement position 18 to clamp the analysis tray 17 containing the filter press bottle assembly and move it to the next process. Specifically, the analysis tray discharge assembly 4 moves as follows: first, the Y-axis transfer module 41 of the analysis tray moves the Z-axis transfer module 42 of the analysis tray in the Y-axis direction, thereby driving the second clamping device 43 located on the Z-axis transfer module 42 of the analysis tray to move along the Y-axis direction. At the same time as the Z-axis transfer module 42 of the analysis tray moves in the Y-axis direction, the Z-axis transfer module 42 of the analysis tray can also synchronously drive the second clamping device 43 to move along the Z-axis direction.

[0072] In one specific implementation, see Figure 6 The second gripping device 43 includes a second gripper and a second gripper finger. The second gripper can be an electric gripper or a pneumatic gripper. The second gripper controls the opening and closing movement of the second gripper finger. The second gripper finger is L-shaped and there are two of them. The two second gripper fingers cooperate with each other to grip the analysis disk 17. Specifically, the second gripper finger includes a connecting arm and a clamping arm. The connecting arm is connected to the second gripper. The clamping arm is used to grip the analysis disk 17. The outer wall of the analysis disk 17 is recessed inward to form a clamping groove. The clamping groove cooperates with the clamping arm to make the clamping arm grip the analysis disk 17 more stably and less likely to fall off or tilt.

[0073] In one specific embodiment, the entire process of completing the analysis and discharge operation involves the following movement: the analysis disc transfer module 16 moves the analysis disc 17 to the filter press flask assembly placement position 18, and then the filter press transfer module 31 moves the first clamping device 32 to clamp the filter press flask assembly that has completed filtration and is placed at the filter press position 12. The filter press transfer module 31 includes a filter press X-axis transfer module 311 and a filter press Z-axis transfer module 312. The filter press X-axis transfer module 311 moves the filter press Z-axis transfer module 312 to the filter press position 12 in the X-axis direction, and the filter press Z-axis transfer module 312 moves the first clamping device 32 along the X-axis direction. The filter press flask assembly that has completed filtration is moved along the Z-axis to the filter press position 12. The filter press X-axis transfer module 311 moves along the X-axis to the filter press flask assembly placement position 18, placing the filter press flask assembly on the analysis tray 17. Then, the analysis tray Y-axis transfer module 41 drives the analysis tray Z-axis transfer module 42 to move along the Y-axis to the filter press flask assembly placement position 18. The analysis tray Z-axis transfer module 42 drives the second clamping device 43 to move along the Z-axis to clamp the analysis tray 17 containing the filter press flask assembly. Finally, the analysis tray 17 containing the filter press flask assembly is moved by the analysis tray Y-axis transfer module 41 to the next process, completing the analysis and discharge. This application is not limited to the above-described order of operations. That is, those skilled in the art can also choose a suitable judgment order or perform several operations and steps simultaneously as needed, and this application does not impose any restrictions on this. By installing the analysis tray discharge assembly 4 next to the filter press, the filter press flasks containing the filtrate after filtration can be moved to the next process, saving time, improving efficiency, and avoiding manual movement of the filter press flasks by laboratory personnel. This achieves automated analysis, solves the problems of low manual production efficiency, reduces analysis costs, improves analysis efficiency, avoids hand contamination for laboratory personnel, and meets the requirements of high-intensity work.

[0074] In one specific implementation, see Figure 7 When the bottom of the first filter press flask 14 is provided with a first support portion for placing the first filter press membrane, and the bottom of the second filter press flask 15 is sealed, the target filter press flask is the second filter press flask 15.

[0075] When a support membrane is embedded at the bottom of the first filter press flask 14, and a second support portion for placing the second filter press membrane is provided opposite to the bottom of the second filter press flask 15, the target filter press flask is the first filter press flask 14.

[0076] The first and second filter membranes are both unidirectional filter membranes, and their directions are different. The first and second support parts can be formed by multiple intersecting support rods, or they can be other support components formed in a way that allows the reaction liquid to pass through. No restrictions are imposed here.

[0077] When the filter press flask assembly is configured such that the bottom of the first filter press flask 14 has a first support portion for placing the first filter press membrane, and the bottom of the second filter press flask 15 is sealed, the pipetting and transfer module 21 moves the pipetting assembly 22 containing the reaction liquid to the top of the filter press flask assembly, and the controller controls the pipetting assembly 22 to inject the reaction liquid into the second filter press flask 15; the filter press flask assembly carrier 13 carries the second filter press flask 15 containing the injected reaction liquid, and the filter press flask assembly transfer module 11 moves the filter press flask assembly carrier 13 to the filter press position 12; the filter press transfer module 31 drives the first clamping device 32 to clamp the first filter press flask 14 and move it to the filter press position 12, cooperating with the second filter press flask 15 located at the filter press position 12, and applying pressure to the second filter press flask 15 through the first filter press flask 14, so that the reaction liquid in the second filter press flask 15 is filtered through the filter press membrane to the first filter press flask 14, completing the filter press.

[0078] When the filter press flask assembly is configured such that the bottom of the first filter press flask 14 is embedded with a support membrane, and the second filter press flask 15 is provided with a second support portion for placing the second filter press membrane away from the bottom, the pipetting and transfer module 21 moves the pipetting assembly 22 containing the reaction liquid to the top of the filter press flask assembly, and the controller controls the pipetting assembly 22 to inject the reaction liquid into the first filter press flask 14; the filter press flask assembly transfer module 11 moves the filter press flask assembly carrier 13, which is loaded with the second filter press flask 15 without the reaction liquid, to the filter press position 12; the filter press transfer module 31 drives the first clamping device 32 to clamp the first filter press flask 14 and move it to the filter press position 12, cooperating with the second filter press flask 15 located at the filter press position 12, and applying pressure from the first filter press flask 14 to the second filter press flask 15, so that the reaction liquid in the first filter press flask 14 is filtered through the filter press membrane into the second filter press flask 15, completing the filter press.

[0079] In one specific implementation, see Figure 3 There are at least two sets of filter press flask transfer modules 11, which are arranged adjacent to the analysis tray transfer module 16 parallel to the Y-axis. Specifically, at least one set of filter press flask transfer modules 11 has a filter pressing position 12 at one end. The first filter press flask carrier can be placed on one set of filter press flask transfer modules 11, and the second filter press flask carrier can be placed on the other set of filter press flask transfer modules 11. Alternatively, the first filter press flask carrier and the second filter press flask carrier can be placed on each set of filter press flask transfer modules 11 simultaneously. By setting up two sets of filter press flask transfer modules 11, when the first filter press flask 14 and / or the second filter press flask 15 in one set of filter press flask transfer modules 11 are used up, the next set can be used directly, which can save time and improve efficiency.

[0080] In one specific implementation, see Figure 4 and Figure 8The pipetting module 21 includes a pipetting X-axis transfer module 211 and a pipetting Y-axis transfer module 212. The pipetting X-axis transfer module 211 is disposed above the filter press assembly transfer module 11. Specifically, the pipetting X-axis transfer module 211 can also be disposed on the side close to the filter press assembly transfer module 31, and disposed on the support arm 62. The Y-axis transfer module 212 and the Y-axis transfer module 41 of the analysis tray are arranged parallel to each other along the Y-axis. The Y-axis transfer module 212 is driven by the X-axis transfer module 211 to move along the X-axis. At the same time, the Y-axis transfer module 212 also drives the pipetting assembly 22 to move along the Y-axis. Thus, through the linkage of the X-axis transfer module 211 and the Y-axis transfer module 212, the pipetting assembly 22 moves above at least two sets of filter press flask transfer modules 11, making the movement more precise and stable.

[0081] In one specific implementation, see Figure 5 The filter press transfer module 31 includes a filter press X-axis transfer module 311 and a filter press Z-axis transfer module 312. The filter press X-axis transfer module 311 is located above the X-axis where the filter press position 12 is located. The filter press X-axis transfer module 311 and the liquid transfer X-axis transfer module 211 are arranged parallel to the X-axis at both ends of the worktable. The filter press Z-axis transfer module 312 is provided with a first clamping device 32. Specifically, the filter press Z-axis transfer module 312 and the first clamping device are... The first clamping device 32 is set parallel to the Z-axis direction. The filter press X-axis transfer module 311 drives the filter press Z-axis transfer module 312 to move along the X-axis direction. When the filter press Z-axis transfer module 312 moves along the X-axis direction, it also synchronously drives the first clamping device 32 to move along the Z-axis direction. This achieves linkage between the filter press X-axis transfer module 311 and the filter press Z-axis transfer module 312 to drive the first clamping device 32 to move. This makes the movement more precise and stable.

[0082] In one specific implementation, see Figure 9 A receiving component 5 is provided directly below the pipetting component 22. The receiving component 5 is used to collect the reaction liquid dripped from the pipetting component 22. The receiving component 5 moves synchronously with the pipetting component, which facilitates the pipetting operation of the pipetting component in the entire working area. The receiving component 5 collects the dripping liquid in time, avoiding secondary contamination of the reaction liquid.

[0083] The liquid receiving assembly 5 includes a liquid receiving tank 51, a drive mechanism 53, and a mounting plate 54 for connecting to the liquid transfer assembly 22. The drive mechanism 53 drives the liquid receiving tank 51 to move.

[0084] In one specific embodiment, the liquid receiving assembly 5 further includes a guide rod 52, which and the drive mechanism 53 are arranged parallel to each other at both ends of the liquid receiving tank 51. The drive mechanism 53 drives the guide rod 52 to act on the liquid receiving tank 51. The guide rod 52 causes the liquid receiving tank 51 to move horizontally, making the movement of the liquid receiving tank 51 more stable.

[0085] In one specific implementation, see Figure 1 The filter press system also includes a support assembly 6, which includes a support column 61 and a support arm 62 arranged perpendicularly to the support column 61.

[0086] The support column 61 is used to support the liquid transfer module 21, the filter press transfer module 31, the analytical plate discharge assembly 4 and the support arm 62;

[0087] The pipetting module 21 and the analytical tray dispensing assembly 4 are mounted on the support arm 62 and are slidably connected. Specifically, the two ends of the pipetting Y-axis transfer module 212 and the analytical tray Y-axis transfer module 41 are slidably connected to the two support arms 62. The slidable connection can be achieved by one of them having a raised slide rail and the other having a groove that mates with the slide rail; alternatively, one of them can have a groove and the other can be a slider. Furthermore, the analytical tray dispensing assembly 4 is mounted on the support arm 62 and the pipetting X-axis transfer module 211, saving space and simplifying the assembly process.

[0088] In one specific embodiment, the pressure filtration system also includes a dilution component for holding diluent. A mounting plate is provided on the pipetting module 21, with the pipetting component 22 mounted on one side and the dilution component mounted on the other. If dilution is required in the pressure filtration step, the dilution component will inject the corresponding amount of diluent under the control of the host computer. If dilution is not required in the pressure filtration step, the dilution component will not start. Simultaneous configuration of the pipetting and dilution components improves production efficiency, reduces equipment footprint, and enables batch processing of pipetting or dilution. Specifically, the dilution component moves by the pipetting X-axis transfer module 211 driving the pipetting Y-axis transfer module 212 along the X-axis. Simultaneously, the pipetting Y-axis transfer module 212 also drives the dilution component to move along the Y-axis. Thus, the pipetting X-axis transfer module 211 and the pipetting Y-axis transfer module 212 work together to move the dilution component above the pressure flask assembly transfer module 11. This enables the X-axis and Y-axis pipetting modules 211 to work together to drive the dilution assembly into the target filter press flask to perform the dilution operation. Multiple pipetting assemblies can be used, for example, three, to complete the dilution operation simultaneously. A receiving assembly 5 can also be installed directly below the dilution assembly to collect any dripping reaction liquid, effectively preventing secondary contamination.

[0089] The dilution component, controlled by a controller, injects the diluent into the target filter press flask to complete the dilution operation. This automates the dilution process, solving the problems of low manual production efficiency, reducing dilution costs, improving dilution efficiency, avoiding hand contamination for test personnel, and meeting the requirements of high-intensity operations.

[0090] This application also provides a pressure filtration method, which includes:

[0091] The pipetting module 21 moves the pipetting assembly 22 containing the reaction solution to above the filter press flask group, and the controller controls the pipetting assembly 22 to inject the reaction solution into the target filter press flask; the target filter press flask is either the first filter press flask or the second filter press flask.

[0092] The filter press bottle transfer module 11 moves the filter press bottle carrier 13 to the filter press position 12, where the filter press bottle carrier 13 is loaded with a second filter press bottle.

[0093] The pressure filtration transfer module 31 drives the first clamping device 32 to clamp the first pressure filtration bottle 14 and move it to the pressure filtration position 12, and cooperate with the second pressure filtration bottle 15 located at the pressure filtration position 12. The first pressure filtration bottle 14 applies pressure to the second pressure filtration bottle 15 so that the reaction liquid in the target pressure filtration bottle is filtered through the pressure filtration membrane.

[0094] In one specific implementation, the working steps of the pressure filtration method can be as follows:

[0095] S1: The pipetting module 21 moves the pipetting assembly 22 containing the reaction solution to above the filter press flask group, and the controller controls the pipetting assembly 22 to inject the reaction solution into the target filter press flask; the target filter press flask is either the first filter press flask or the second filter press flask.

[0096] S2: The filter press bottle group transfer module 11 moves the filter press bottle group carrier 13 to the filter press position 12, where the filter press bottle group carrier 13 is loaded with a second filter press bottle.

[0097] S3: The pressure filtration transfer module 31 drives the first clamping device 32 to clamp the first pressure filtration bottle 14 and move it to the pressure filtration position 12, and cooperate with the second pressure filtration bottle 15 located at the pressure filtration position 12. The first pressure filtration bottle 14 applies pressure to the second pressure filtration bottle 15 so that the reaction liquid in the target pressure filtration bottle is filtered through the pressure filtration membrane.

[0098] In another specific embodiment, the working steps of the pressure filtration method can be as follows:

[0099] S1: The filter press bottle group transfer module 11 drives the filter press bottle group carrier 13 to the filter press position 12, where the filter press bottle group carrier 13 is loaded with a second filter press bottle.

[0100] S2: The pipetting module 21 moves the pipetting assembly 22 containing the reaction solution to above the filter press flask group, and the controller controls the pipetting assembly 22 to inject the reaction solution into the target filter press flask; the target filter press flask is either the first filter press flask or the second filter press flask.

[0101] S3: The pressure filtration transfer module 31 drives the first clamping device 32 to clamp the first pressure filtration bottle 14 and move it to the pressure filtration position 12, and cooperate with the second pressure filtration bottle 15 located at the pressure filtration position 12. The first pressure filtration bottle 14 applies pressure to the second pressure filtration bottle 15 so that the reaction liquid in the target pressure filtration bottle is filtered through the pressure filtration membrane.

[0102] It should be noted that the exemplary embodiments mentioned in this application describe methods and systems based on a series of operations or devices. However, this application is not limited to the order of the above operations. That is, those skilled in the art can also choose a suitable order of judgment or perform several operations and steps simultaneously as needed, and this application does not impose any restrictions on this.

[0103] In one specific embodiment, the filtration and analysis operation is as follows: the X-axis transfer module 211 drives the Y-axis transfer module 212 to move along the X-axis. Simultaneously, the Y-axis transfer module 212 also drives the pipetting assembly 22 to move along the Y-axis. Through the coordinated movement of the X-axis and Y-axis transfer modules 211 and 212, the pipetting assembly 22, containing the reaction solution, moves above the filtration flask assembly. Under the control of the controller, the pipetting assembly 22 injects the reaction solution into the target filtration flask. Inside the bottle, the filter bottle assembly carrier 13, which carries the second filter bottle 15, is moved to the filter position 12 by the filter bottle assembly transfer module 11. Finally, the filter X-axis transfer module 311 moves the filter Z-axis transfer module 312 along the X-axis to the filter position 12. The filter Z-axis transfer module 312 moves the first clamping device 32 along the Z-axis to clamp the first filter bottle 14, making the first filter bottle and the second filter bottle coaxial and cooperating with the second filter bottle 15 located at the filter position. The first filter bottle 14 applies pressure to the second filter bottle 15 so that the reaction liquid in the target filter bottle is filtered through the filter membrane. After filtration is completed, the analysis plate transfer module 16 moves the analysis plate 17 to the filter bottle assembly placement position 18. Then, the first clamping device 32 moves along the Z-axis direction to clamp the filter bottle assembly on the filtration position 12 via the filtration Z-axis transfer module 312. The filtration X-axis transfer module 311 moves along the X-axis direction to the filter bottle assembly placement position 18 and places the filter bottle assembly on the analysis plate 17. Then, the analysis plate Z-axis transfer module 42 moves along the Y-axis direction to the filter bottle assembly placement position 18 via the analysis plate Y-axis transfer module 41. The analysis plate Z-axis transfer module 42 moves along the Z-axis direction to the filter bottle assembly placement position 18. The analysis plate Z-axis transfer module 42 moves the second clamping device 43 along the Z-axis direction to clamp the analysis plate 17 containing the filter bottle assembly. Finally, the analysis plate 17 containing the filter bottle assembly is moved to the next process via the analysis plate Y-axis transfer module 41 to complete the analysis and discharge.

[0104] This filter press system achieves automated connection between multiple filter press processes by setting up multi-directional transfer modules, thus realizing automated filter press. It solves the problems of low manual production efficiency, reduces filter press costs, improves filter press efficiency, and avoids hand contamination for test personnel, meeting the requirements of high-intensity operations. The decentralized flow of multiple modules working together shortens the spatial distance between each operation step in the filter press process, reduces transportation and waiting time between each operation step, and makes the flow between different operation steps more convenient. It can significantly improve the working efficiency of the filter press process and simultaneously meet the requirements of high-throughput experimental processing.
