Description

A timed and quantitative speed-regulating filter Technical Field

[0001] This application relates to the field of filter technology, and in particular to a timed and quantitative speed-regulating filter. Background Technology

[0002] Filters are core tools in laboratories for sample separation, purification, sterilization, and grading. They separate target substances from impurities through physical retention or adsorption, providing a suitable sample matrix for subsequent detection or analysis. However, existing filters require manual inversion of the stock solution during operation. When the operator manually pours or pipettes the solution, it is difficult to accurately control the volume of the stock solution, resulting in insufficient sample addition accuracy. Furthermore, manual operation is prone to errors, leading to unreliable results. In addition, manual operation requires processing one sample at a time, making it impossible to perform other experimental steps simultaneously, resulting in low time utilization and significant limitations in efficiency and accuracy. Summary of the Invention

[0003] The purpose of this invention is to provide a timed and quantitative speed-regulating filter to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows:

[0005] This application provides a timed and quantitative speed-adjustable filter, including a base, a peristaltic pump mounted on the base, a material cup and a support frame located on both sides of the peristaltic pump, a support plate on the support frame, and several filter components spaced apart on the support plate. Each filter component includes a filter support and a filter cover. The filter support is mounted on the support plate, has a cavity inside and a filter element is installed thereon, and a liquid outlet pipe is provided at the bottom of the filter support. The filter cover is movably mounted on the filter support, so that the filter element is located between the filter cover and the filter support.

[0006] The filter cover has a connecting tube, on which a filter cup is movably mounted. The peristaltic pump has several pump heads, each equipped with an infusion tube. One end of the infusion tube is located above the filter cup, and the other end is located inside the feed cup.

[0007] The outlet pipe is connected to a flow detection component via a pipeline. A pipe body is also installed on the support frame, and several spaced-apart liquid storage tanks are installed on the pipe body. The inside of the pipe body is connected to the liquid storage tanks, and the liquid storage tanks are connected to the other end of the flow detection component via a pipeline.

[0008] In one embodiment, a blocking component is provided inside the liquid storage tank. The blocking component includes a support shaft, which is rotatably disposed inside the liquid storage tank. One end of the support shaft extends to the outside of the liquid storage tank and is equipped with a handwheel.

[0009] Baffles are provided on both sides of the support shaft. The rotation of the support shaft makes the baffles parallel or perpendicular to the end face of the liquid storage tank.

[0010] In one embodiment, the outer periphery of the filter support is provided with a convex thread, and the inner wall of the filter cover is provided with a threaded groove that matches the convex thread. Through the cooperation of the convex thread and the threaded groove, the filter cover is threadedly connected to the filter support.

[0011] In one embodiment, a water pump is also provided on the base, and a liquid outlet is provided at one end of the pipe body. The liquid outlet is connected to the water pump through a pipeline.

[0018] The advantages or beneficial effects of the above technical solutions include at least the following:

[0019] This application discloses a timed and quantitative adjustable speed filter. The filter involves placing the required raw solution in a single cup or inverting different raw solutions in different cups. The delivery tubes of different pump heads on a peristaltic pump are placed on the single or different cups and, with the assistance of the peristaltic pump, deliver the solution to different filter cups. The solution then flows through the filter cups into the filtration unit, achieving filtration of a single or different raw solutions. Since the filter cover in the filtration unit is movably mounted on the filter support and connected to the filter cup, the filter cup can be replaced by changing the filter cover with a different diameter, thereby altering the flow rate of the raw solution. The filtered liquid is discharged from the filter support and enters a flow detection unit for flow rate monitoring, thus determining the filtration resistance of the raw solution. The filtered liquid is then stored in a storage tank. Through the cooperation of the filtration unit and a multi-pump peristaltic pump, simultaneous filtration of multiple samples under multiple conditions can be achieved, thereby improving the comprehensiveness of the detection and solving the problem of low detection efficiency caused by the need for manual operation in existing filtration processes.

[0040] Referring to Figures 1-5, a timed and quantitative speed-regulating filter includes a base 1, which serves as the support structure for the entire filter, ensuring the stability of each component and reducing vibration and displacement during operation. A peristaltic pump 2 is mounted on the base 1. The base 1 also includes a material cup 11 and a support frame 3 located on either side of the peristaltic pump 2. The material cup 11 stores the liquid to be filtered, providing a stable liquid supply for the filtration process. One or more material cups 11 can be provided; multiple material cups 11 allow for simultaneous filtration of different liquids. The support frame 3 has a support plate 31, on which several spaced-apart filter components 4 are mounted. Each filter component 4 includes a filter support 41 and a filter cover. 42. The filter support 41 is mounted on the support plate 31. The support plate 31 has mounting holes, which can flexibly adjust the installation or removal of the filter support 41. The filter support 41 has a cavity and a filter element is installed inside. An annular protrusion is provided in the cavity for placing the filter element. The filter element is the core filtration element, which is used to trap impurity particles in the liquid. The filter support 41 and the filter cover 42 form a sealed filtration space. By replacing filter elements with different pore sizes, different filtration precision requirements can be achieved. The bottom of the filter support 41 is provided with a liquid outlet pipe 411. The filter cover 42 is movably mounted on the filter support 41, so that the filter element is located between the filter cover 42 and the filter support 41.

[0041] The filter cover 42 has a connecting pipe 421, on which a filter cup 5 is movably mounted. Since the filter cover 42 is movably mounted on the filter support 41, different sizes of filter cups 5 can be adapted by replacing filter covers 42 with different diameters, improving the flexibility of use. The filter cup 5 serves as a flow guide. The peristaltic pump 2 has several pump heads 21, each equipped with a delivery pipe 211. One end of the delivery pipe 211 is located above the filter cup 5, and the other end is located inside the material cup 11. The peristaltic pump 2 acts as a power source, using the pump heads 21 to compress the delivery pipe 211 to achieve liquid delivery. The multi-pump head design allows for the simultaneous processing of multiple filtration channels, improving filtration efficiency and achieving precise flow control. By adjusting the pump speed, the liquid delivery volume and speed can be precisely controlled to meet the requirements of timed and quantitative filtration. The multi-channel design allows the equipment to simultaneously handle different specifications or types of filtration tasks, enhancing the applicability and flexibility of the equipment.

[0042] The outlet pipe 411 is connected to a flow detection component 6 via a pipeline. The flow detection component 6 can provide flow data feedback, allowing the testing personnel to judge the filtration resistance by measuring the filtration speed and flow rate over a certain period of time. The support frame 3 is also equipped with a pipe body 7, on which several spaced liquid storage tanks 71 are installed. The interior of the pipe body 7 is connected to the liquid storage tanks 71. The liquid storage tanks 71 are connected to the other end of the flow detection component 6 via a pipeline. The pipe body 7 serves as the main channel for liquid transportation, connecting multiple liquid storage tanks 71 together. The liquid storage tanks 71 are used to store the filtered liquid.

[0043] Based on the above structure, by inverting the raw liquid to be tested into the material cup 11, and with one end of the infusion tube 211 connected to the pump head 21 of the peristaltic pump 2 located in the material cup 11, the raw liquid in the material cup 11 is delivered to the other end located above the filter cup 5 by the peristaltic pump 2 in a timed and quantitative manner according to actual needs. Since the pump head 21 of the peristaltic pump 2 is equipped with several pumps, it can extract different or the same raw liquid, enabling multiple sets of tests to be performed simultaneously. When the raw liquid is in the filter cup 5, it flows along the filter cup 5 into the connecting tube 421 in the filter cover 42 and into the filter support 41. The filter cover 42 can be replaced according to the different filter cups 5 required, changing the diameter of the connecting tube 421, thereby changing the flow rate of the liquid, and then into the filter support 41. The filter in section 1 filters the raw liquid, causing impurities or particulate matter in the raw liquid to be located on the filter for subsequent cultivation or detection. The filtered liquid flows into the flow detection component 6 through the outlet pipe 411. The flow detection component 6 can determine the flow rate of the liquid, thereby detecting the filtration resistance of the raw liquid. Subsequently, the liquid enters the storage tank 71 and then enters the pipe body 7 to complete the collection of waste liquid. Through the cooperation of the peristaltic pump 2 with multiple pump heads 21 and the filter component 4, multiple samples can be detected simultaneously, and the flow rate can be adjusted according to actual needs, thereby improving the comprehensiveness and accuracy of detection. This solves the problem that the existing filtration operation requires manual participation at each stage, which is prone to errors and has slow operation efficiency.

[0044] In one embodiment, referring to Figures 1, 3 and 4, a blocking component 711 is provided inside the liquid storage tank 71. The blocking component 711 includes a support shaft 7111, which is rotatably disposed inside the liquid storage tank 71. One end of the support shaft 7111 extends to the outside of the liquid storage tank 71 and is equipped with a handwheel 7112. Both ends of the support shaft 7111 are fixed to the side wall of the liquid storage tank 71 by bearings.

[0045] Baffles 7113 are provided on both sides of the support shaft 7111. Rotation of the support shaft 7111 allows the baffles 7113 to be parallel or perpendicular to the end face of the liquid storage tank 71. Rubber sealing strips are provided on both sides, forming a seal when in contact with the inner wall of the liquid storage tank 71 to prevent liquid leakage. Changing the parallel or perpendicular position allows for the flow or storage of liquid in the liquid storage tank 71. When the handwheel 7112 is turned clockwise, the support shaft 7111 drives the baffles 7113 to rotate perpendicular to the end face of the liquid storage tank 71, gradually blocking the liquid passage. When the baffles 7113 are completely perpendicular, the connection between the liquid storage tank 71 and the pipe body 7 is blocked, stopping the inflow or outflow of liquid. When the handwheel 7112 is turned counterclockwise, the baffles 7113 gradually become parallel to the end face of the liquid storage tank 71, fully opening the liquid passage and allowing free liquid flow, meeting the liquid storage requirements of a normal filtration process. The storage of liquid in the liquid storage tank 71 prevents the mixing of different liquids in the pipe body 7.

[0046] In one embodiment, referring to Figures 2, 3, and 6, the outer periphery of the filter support 41 is provided with a protruding thread 412, and the inner wall of the filter cover 42 is provided with a threaded groove 422 that matches the protruding thread 412. Through the cooperation of the protruding thread 412 and the threaded groove 422, the filter cover 42 is threadedly connected to the filter support 41. Through the cooperation of the protruding thread 412 and the threaded groove 422, the filter cover 42 can be quickly sealed and disassembled. The self-locking characteristic of the threaded connection ensures that there is no loosening during the filtration process. When the filter cover 42 is tightened, it generates uniform pressure on the filter sheet, ensuring that the filter sheet is flat and fits against the sealing surface of the filter support 41, avoiding filtration failure caused by filter sheet displacement. At the same time, it is convenient to replace the filter cover 42 with different connecting pipes 421.

[0047] In one embodiment, referring to Figures 1 and 2, a water pump component 8 is also provided on the base 1. One end of the pipe body 7 is provided with a liquid outlet interface, which is connected to the water pump component 8 through a pipeline. The water pump component 8 is a centrifugal pump. One end of the pipe body 7 is provided with a liquid outlet interface, which is connected to the inlet pipeline of the water pump component 8 by a flange connection, so that the water pump component 8 can extract and collect the wastewater in the pipe body 7.

[0048] In one embodiment, referring to Figures 1 and 5, the top of the filter cup 5 has a guide portion 51. The outer diameter of the guide portion 51 is larger than the outer diameter of the filter cup 5. The guide portion 51 is flared and has an inclined end 511. The flared structure of the guide portion 51 increases the liquid receiving area. When the nozzle of the infusion tube 211 injects liquid into the filter cup 5, even if the liquid flow rate is fast, the inclined end 511 can effectively guide the splashed liquid into the interior of the filter cup 5, preventing liquid from splashing out and causing waste or pollution. Furthermore, when the liquid flows into the filter cup 5 through the inclined end 511, the flow rate and direction change, which helps to release dissolved air bubbles in the liquid.

[0049] In one embodiment, referring to Figures 1-3, the flow detection component 6 is a flow sensor with communication function. The flow sensor collects the liquid flow data in the liquid outlet pipe 411 in real time and automatically adjusts the speed of the peristaltic pump 2 according to the preset flow threshold to achieve timed and quantitative filtration.

[0050] The peristaltic pump 2 is a multi-channel peristaltic pump 2. The number of channels can be configured according to requirements, such as 4 channels, 6 channels, or 8 channels. Each channel is independently controlled and different flow parameters can be set. The multi-channel design allows the liquid from multiple filtration channels to be processed simultaneously. Each channel can independently set the flow rate and running time to achieve the synchronous execution of different filtration processes. Each pump head 21 is equipped with an independent drive motor and encoder to meet the precise flow requirements of different filtration stages.

[0051] In one embodiment, referring to Figures 1 and 2, a controller 12 is also provided on the base 1. The controller 12 adopts a programmable controller in the prior art, equipped with a touch screen, supports human-machine interaction, and can display the equipment operating status, flow data, fault information, etc. in real time. The controller 12 is electrically connected to the peristaltic pump 2 and the water pump 8, and is communicatively connected to the flow detection component 6. The controller 12 is connected to the peristaltic pump 2 and the water pump 8 through relays and frequency converters to achieve precise control of the motor speed. It is connected to the flow detection component 6 through a communication cable to receive flow data in real time. It integrates a PID control algorithm and can automatically adjust the equipment operating status according to the set flow and time parameters. The operator only needs to input the filtration parameters on the touch screen, and the controller 12 can automatically start the peristaltic pump 2 and the water pump 8. Based on the feedback data from the flow detection component 6, it can determine the filtration resistance and achieve high-precision filtration operation.
