Description

Technical Field

[0001] This utility model relates to the field of cigarette machinery and equipment technology, and more specifically, to a rotary automatic filtration device. Background Technology

[0002] Filter-type chromatography bottles are tools based on the traditional method of filtering chromatographic samples before adding test solvents to the bottle and then using a chromatograph for testing.

[0003] During the existing experimental procedures, the researchers found that the current operation of the filter-type chromatography bottle requires the researchers to manually add the test solvent into the filter-type chromatography bottle using a syringe. During the filtration process, the researchers also need to apply pressure slowly and evenly by hand, otherwise the filter membrane may be damaged or the liquid may spray out from the interface and cause injury.

[0004] Furthermore, because the gap between the body and the cap of the filter-type chromatography bottle is very tight in order to ensure filtration efficiency, the experimenter needs to exert a lot of force to press it in manually. This not only affects the operation efficiency, but also makes it easy to lose control of the force, causing some of the test solution to spill out during the connection process. As a result, the operation of the filter-type chromatography bottle is time-consuming and laborious.

[0005] Therefore, how to provide a rotary automatic filtration device has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] One objective of this invention is to provide a new technical solution for a rotary automatic filtration device.

[0007] According to a first aspect of the present invention, a rotary automatic filtration device is provided, comprising: a base, a fixing component, and an automatic squeezing component;

[0008] The fixing assembly includes a rotating rod and a first turntable, a second turntable, and a third turntable arranged sequentially from bottom to top. The first end of the rotating rod is rotatably connected to the base, and the second end of the rotating rod passes through the first turntable and the second turntable in sequence, and is connected to the third turntable, so as to drive the first turntable, the second turntable, and the third turntable to rotate synchronously. The first turntable has multiple placement slots for placing chromatographic bottles, the second turntable has multiple mounting holes for placing syringe-type membrane filters, and the third turntable has corresponding fixing holes for placing syringes.

[0009] The first end of the automatic squeezing assembly is disposed on the base, and the second end of the automatic squeezing assembly is located above the third turntable. The automatic squeezing assembly is used to squeeze the syringe so that the solution in the syringe drips into the syringe-type membrane filter.

[0010] Optionally, the placement slot, the mounting hole, and the fixing hole each have six.

[0011] Optionally, the syringe-type membrane filter includes a syringe and a filter membrane connected to the syringe. The diameter of the mounting hole is smaller than the diameter of the filter membrane and larger than the diameter of the syringe. The syringe is inserted into the mounting hole and is positioned toward the chromatographic vial in the placement slot.

[0012] Optionally, the orthographic projection of the center of the fixing hole coincides with the center of the mounting hole and the center of the placement groove.

[0013] Optionally, the distance between the first and second turntables is equal to the height of the chromatographic vial, and the distance between the second and third turntables is less than the length of the syringe.

[0014] Optionally, the second turntable and the third turntable are slidably connected to the rotating rod, and the first turntable is fixedly connected to the rotating rod.

[0015] Optionally, the fixing component further includes a first drive motor, which is disposed on the base and located below the first turntable, and the output shaft of the first drive motor is connected to the rotating rod.

[0016] Optionally, the automatic extrusion assembly includes a support rod, a connecting plate, a second drive motor, and an extrusion column. The first end of the support rod is connected to the base, and the second end of the support rod is perpendicularly connected to the first end of the connecting plate. The second drive motor is disposed on the second end of the connecting plate, and the output shaft of the second drive motor is connected to the extrusion column for driving the extrusion column to move up and down.

[0017] Optionally, the length of the support rod is greater than the sum of the length of the rotating rod and the length of the syringe, and the squeezing column is located above the syringe.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention connects the first end of a rotating rod to a base, and the second end of the rotating rod passes through a first and a second turntable, connecting to a third turntable. The first turntable has multiple slots for placing chromatographic vials, the second turntable has multiple mounting holes for syringe-type membrane filters, and the third turntable has mounting holes for syringes. The first end of the automatic squeezing assembly is positioned on the base, and the second end is located above the third turntable. In use, the operator places the chromatographic vial, syringe-type membrane filter, and syringe into the slots, mounting holes, and mounting holes respectively. The automatic squeezing assembly is then activated, and the rotating rod is rotated. This causes the automatic squeezing assembly to squeeze the syringes on the third turntable, causing the solution inside the syringes to drip into the syringe-type membrane filter. After filtration by the syringe-type membrane filter, the solution slowly flows into the chromatographic vial, improving detection efficiency and avoiding problems such as solution overflow from the chromatographic vial, damage to the syringe-type membrane filter, and injury to the operator caused by liquid spraying from the interface due to manual squeezing of the syringes. It also reduces the operator's workload.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] like Figure 1 As shown, this utility model embodiment provides a rotary automatic filtering device, including: a base 1, a fixing component 2, and an automatic squeezing component 3.

[0029] The fixed assembly 2 includes a rotating rod 24 and a first turntable 21, a second turntable 22 and a third turntable 23 arranged sequentially from bottom to top. The first end of the rotating rod 24 is rotatably connected to the base 1, and the second end of the rotating rod 24 passes through the first turntable 21 and the second turntable 22 in sequence and is connected to the third turntable 23 so as to drive the first turntable 21, the second turntable 22 and the third turntable 23 to rotate synchronously.

[0030] The first turntable 21 has multiple placement slots 25 for placing chromatographic bottles, the second turntable 22 has multiple mounting holes 26 for placing syringe-type membrane filters, and the third turntable 23 has corresponding fixing holes 27 for placing syringes.

[0031] Specifically, the diameter of the placement groove 25 is the same as the diameter of the chromatography bottle, and the depth of the placement groove 25 is slightly less than the depth of the chromatography bottle, so as to ensure the stable storage of the chromatography bottle while making it easy to take out the chromatography bottle.

[0032] The first end of the automatic squeezing assembly 3 is set on the base 1, and the second end of the automatic squeezing assembly 3 is located above the third turntable 23. The automatic squeezing assembly 3 is used to squeeze the syringe so that the solution in the syringe drips into the syringe-type membrane filter.

[0033] In use, the operator places multiple chromatographic vials, multiple syringe-type filter membranes, and multiple syringes into the corresponding placement slots 25, mounting holes 26, and fixing holes 27. Then, the automatic squeezing assembly 3 is activated, moving it towards the third turntable 23 to squeeze the syringe located directly below it. This causes the solution in the syringe to drip into the syringe-type filter membrane. After filtration by the syringe-type filter membrane, the solution slowly filters into the chromatographic vials.

[0034] After completing the squeezing process, the automatic squeezing assembly 3 returns to its initial position. Then, the rotating rod 24 is rotated, causing the first, second, and third turntables 21, 22, and 23 to rotate synchronously. When the next placement slot 25, the next mounting hole 26, and the next fixing hole 27 rotate directly below the automatic squeezing assembly 3, the assembly restarts, squeezing the syringe again. This causes the solution inside the syringe to drip into the syringe-type membrane filter. After filtration, the solution slowly flows into the chromatographic vial. After filtration, the first, second, and third turntables 21, 22, and 23 rotate sequentially with the rotating rod 24 until all samples have been filtered.

[0035] This invention rotatably connects the first end of the rotating rod 24 to the base 1, and the second end of the rotating rod 24 passes through the first turntable 21 and the second turntable 22 in sequence, connecting to the third turntable 23. The first turntable 21 is provided with multiple placement slots 25 for placing chromatographic bottles, the second turntable 22 is provided with multiple mounting holes 26 for placing syringe-type membrane filters, and the third turntable 23 is provided with fixing holes 27 for placing syringes. This allows the first end of the automatic squeezing assembly 3 to be placed on the base 1, and the second end of the automatic squeezing assembly 3 to be located above the third turntable 23. In use, the operator places the chromatographic vial, syringe filter membrane, and syringe into the placement slot 25, mounting hole 26, and fixing hole 27 respectively. The automatic squeezing assembly 3 is activated, and the rotating rod 24 is rotated, causing the automatic squeezing assembly 3 to squeeze multiple syringes on the third turntable 23 in sequence. This causes the solution in the syringes to drip into the syringe filter membrane. After filtration by the syringe filter membrane, the solution slowly filters into the chromatographic vial, improving detection efficiency and avoiding problems such as solution overflow from the chromatographic vial, damage to the syringe filter membrane, and liquid spraying from the interface that could injure the operator due to manual squeezing of the syringe. It also reduces the labor intensity of the operator.

[0036] Furthermore, in order to improve the working efficiency of the rotary automatic filtration device of this utility model, six placement slots 25, mounting holes 26 and fixing holes 27 are provided, thereby enabling the large-scale processing of sample solutions.

[0037] In one embodiment of the rotary automatic filtration device of this utility model, the syringe-type membrane filter includes a syringe and a filter membrane connected to the syringe. The diameter of the mounting hole 26 is smaller than the diameter of the filter membrane and larger than the diameter of the syringe. The syringe is inserted into the mounting hole 26 and is positioned toward the chromatographic bottle in the placement slot 25.

[0038] This invention sets the diameter of the mounting hole 26 to be smaller than the diameter of the filter membrane and larger than the diameter of the syringe, thereby enabling the filter membrane to be stably placed in the mounting hole 26 and the syringe to be stably placed in the mounting hole 26. The syringe is inserted into the mounting hole 26 and oriented towards the chromatographic bottle in the placement groove 25, so that the solution filtered by the filter membrane drips completely into the chromatographic bottle through the syringe.

[0039] In one embodiment of the rotary automatic filtration device of this utility model, the orthographic projection of the center of the fixing hole 27 coincides with the center of the mounting hole 26 and the center of the placement groove 25, thereby enabling the solution in the syringe to fall stably and completely into the syringe filter membrane and the chromatography bottle.

[0040] In one embodiment of the rotary automatic filtration device of this utility model, the distance between the first rotary disk 21 and the second rotary disk 22 is equal to the height of the chromatographic bottle, and the second rotary disk 22 and the third rotary disk 23 are smaller than the length of the syringe, thereby enabling the chromatographic bottle to be stably placed on the first rotary disk 21.

[0041] In one embodiment of the rotary automatic filtration device of this utility model, the second rotary disk 22 and the third rotary disk 23 are slidably connected to the rotating rod 24, and the first rotary disk 21 is fixedly connected to the rotating rod 24.

[0042] Specifically, by slidingly connecting the second turntable 22 and the third turntable 23 to the rotating rod 24, this utility model can adjust the distance between the second turntable 22 and the third turntable 23, as well as the distance between the second turntable 22 and the first turntable 21, by adjusting the positions of the second turntable 22 and the third turntable 23.

[0043] In one embodiment of the rotary automatic filtration device of this utility model, the fixing component 2 further includes a first drive motor 28, which is mounted on the base 1 and located below the first turntable 21. The output shaft of the first drive motor 28 is connected to the rotating rod 24.

[0044] This utility model, by setting the first drive motor 28 on the base 1 and placing the first drive motor 28 below the first turntable 21, and connecting the output shaft of the first drive motor 28 to the rotating rod 24, can ensure that the first drive motor 28 drives the rotating rod 24 to rotate stably, thereby enabling the first turntable 21, the second turntable 22 and the third turntable 23 to rotate stably.

[0045] In one embodiment of the rotary automatic filtration device of this utility model, the automatic extrusion assembly 3 includes a support rod 31, a connecting plate 32, a second drive motor 33, and an extrusion column 34. The first end of the support rod 31 is connected to the base 1, and the second end of the support rod 31 is perpendicularly connected to the first end of the connecting plate 32. The second drive motor 33 is disposed on the second end of the connecting plate 32, and the output shaft of the second drive motor 33 is connected to the extrusion column 34 for driving the extrusion column 34 to move up and down. The orthographic projection of the center of gravity of the extrusion column 34 coincides with the center of the fixing hole 27.

[0046] Specifically, when the placement slot 25, mounting hole 26 and fixing hole 27 are rotated to be directly below the automatic extrusion assembly 3, the second drive motor 33 drives the extrusion column 34 to move toward the third turntable 23, thereby causing the extrusion column 34 to extrude the syringe, causing the solution in the syringe to drip into the syringe-type membrane filter. After being filtered by the syringe-type membrane filter, the solution is slowly filtered into the chromatographic bottle.

[0047] Furthermore, the automatic extrusion assembly 3 also includes a controller and a sensor. The controller is electrically connected to the sensor, the second drive motor 33, and the first drive motor 28. The sensor is mounted on the extrusion column 34 and faces the placement slot 25, the mounting hole 26, and the fixing hole 27. The sensor is used to detect whether the placement slot 25, the mounting hole 26, and the fixing hole 27 have moved to directly below the extrusion column 34.

[0048] When the sensor detects that the placement slot 25, mounting hole 26, and fixing hole 27 have moved directly below the extrusion column 34, the controller stops the first drive motor 28 and starts the second drive motor 33. When the extrusion column 34 completes the extrusion work and moves back to its initial position, the controller stops the second drive motor 33 and starts the first drive motor 28, causing the rotating rod 24 to drive the first turntable 21, the second turntable 22, and the third turntable 23 to rotate.

[0049] In one embodiment of the rotary automatic filtering device of this utility model, in order to ensure that the squeezing column 34 can work stably, the length of the support rod 31 is higher than the sum of the length of the rotating rod 24 and the length of the syringe, and the squeezing column 34 is located above the syringe.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
