Description

Technical Field

[0001] This utility model relates to the field of silica gel chromatography column technology, and in particular to a silica gel chromatography column packing device. Background Technology

[0002] Silica gel chromatography columns are a commonly used chromatographic separation technique, widely applied in the fields of chemistry, biology, and medicine. Laboratories often need to pack silica gel columns themselves. Existing equipment involves first fixing the silica gel column below the delivery tube, then pouring the mixed packing material sequentially from the top of the delivery tube. Subsequently, the pressure line interface is fixed to the top of the delivery tube, supplying uniform pressure to the delivery tube to force the packing material into the silica gel column.

[0003] When pouring the mixed packing material into the delivery tube, the experimenter holds a guide plate in one hand and a measuring cup containing the packing material in the other, pouring it into the delivery tube through the inlet. Due to unstable hand control, the packing material may spill out of the delivery tube, resulting in material waste and environmental pollution. Therefore, a silica gel chromatography column packing device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a silica gel chromatography column packing device to solve the problem mentioned in the background art, where, when pouring the mixed packing into the delivery tube, the experimenter holds a guide plate in one hand and a measuring cup containing the packing in the other, pouring it into the delivery tube from the opening of the delivery tube. Due to unstable hand control, the packing may spill out of the delivery tube, resulting in material waste and environmental pollution.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a silica gel chromatography column packing device, comprising:

[0007] A filling machine, comprising a main body, an angle iron support column, a support rod, and a conveying pipe, wherein the lower end of the angle iron support column is fixed to the side of the main body, the support rod is fixed to the upper end of the angle iron support column, and the conveying pipe is fixed to the support rod;

[0008] A leak-proof assembly includes a clamp, a support plate, a support column, a movable plate, a round through hole, an arc-shaped through hole, a funnel, a first arc-shaped limiting plate, and a second arc-shaped limiting plate. The clamp is held in place on the upper section of the conveying pipe. The support plate is welded to the side of the clamp. The lower end of the support column is rotatably connected to the upper end of the support plate. One end of the movable plate is fixed to the top of the support column. The round through hole is located at the other end of the movable plate away from the support column. The arc-shaped through hole is located on one side of the round through hole. The lower end of the funnel is inserted into the round through hole. The first arc-shaped limiting plate is inserted into the arc-shaped through hole. The second arc-shaped limiting plate is fixed to the upper end of the first arc-shaped limiting plate.

[0009] Furthermore, the funnel is movably connected to the upper end of the conveying pipe, and the outer diameter of the lower end of the funnel is smaller than the inner diameter of the feed inlet of the conveying pipe.

[0010] Furthermore, the filling machine also includes a fixing component, one end of which is fixed by a through support rod and bolts, and the delivery pipe is inserted into the inside of the fixing component.

[0011] Furthermore, it also includes an anti-fouling component, which includes a limiting tube, a semi-circular rod, and a semi-circular receiving box. The lower end of the limiting tube is fixed to the upper end of the support plate and located on both sides of the support column. The lower end of the semi-circular rod is inserted into the limiting tube, and the semi-circular receiving box is fixed to the upper end of the semi-circular rod.

[0012] Furthermore, the anti-fouling component also includes a first arc-shaped groove and a second arc-shaped groove, wherein the first arc-shaped groove is formed in the middle of the side of the semi-circular receiving box, and the second arc-shaped groove is formed at one end of the side of the semi-circular receiving box.

[0013] Furthermore, the first arc-shaped groove is wrapped around the outside of the support column, and the second arc-shaped groove is wrapped around the outside of the conveying pipe.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through the inclusion of a leak-proof component, fixes the clamp to the upper section of the conveying pipe, positioning the funnel outside the pipe. When filler needs to be added, a finger pushes the first arc-shaped limiting plate upwards along the arc-shaped through-hole, causing the movable plate to rotate and the lower support column to rotate around the support plate. When the funnel rotates to directly above the conveying pipe, the first arc-shaped limiting plate is released, falling down, and the second arc-shaped limiting plate adheres to the movable plate. At this point, the first arc-shaped limiting plate wraps around the upper side of the conveying pipe, allowing filler to be poured into the pipe through the funnel. After addition, the funnel is rotated away from the top of the conveying pipe. After all operations are completed, the funnel in the through-hole can be removed and cleaned. This design prevents leakage during filler addition, reducing waste.

[0016] II. This utility model, through the setting of anti-pollution components, allows each hand to hold a semi-circular receiving box, aligning the first arc groove with the support column and the second arc groove with the delivery pipe. After the two semi-circular receiving boxes are joined together, they are pressed down to insert the semi-circular insert rod into the limiting insert tube. When the filling is finished, the funnel rotates away from the delivery pipe, and the filling solution remaining on the inner wall of the funnel slides into the semi-circular receiving box. This setting can avoid contaminating the experimental environment. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-3 As shown, this embodiment is a silica gel chromatography column packing device, including:

[0028] The filling machine includes a main body 10, an angle iron support column 11, a support rod 12, and a conveying pipe 14. The lower end of the angle iron support column 11 is fixed to the side of the main body 10, the support rod 12 is fixed to the upper end of the angle iron support column 11, and the conveying pipe 14 is fixed to the support rod 12.

[0029] The filling machine also includes a fixing member 13, one end of which is fixed by a through support rod 12 and bolts, and the conveying pipe 14 is inserted into the inside of the fixing member 13;

[0030] The main body 10 provides the power for pressurizing the packing, the angle iron support column 11 and the support rod 12 provide support, the fastener 13 provides clamping, and the delivery pipe 14 is used to deliver the packing into the silicone column.

[0031] The leak-proof assembly includes a clamp 20, a support plate 21, a support column 22, a movable plate 23, a round through hole 24, an arc-shaped through hole 25, a funnel 26, a first arc-shaped limiting plate 27, and a second arc-shaped limiting plate 28. The clamp 20 is held in the upper section of the conveying pipe 14. The support plate 21 is welded to the side of the clamp 20. The lower end of the support column 22 is rotatably connected to the upper end of the support plate 21. One end of the movable plate 23 is fixed to the top of the support column 22. The round through hole 24 is opened at the other end of the movable plate 23 away from the support column 22. The arc-shaped through hole 25 is opened on one side of the round through hole 24. The lower end of the funnel 26 is inserted into the round through hole 24. The first arc-shaped limiting plate 27 is inserted into the arc-shaped through hole 25. The second arc-shaped limiting plate 28 is fixed to the upper end of the first arc-shaped limiting plate 27.

[0032] The funnel 26 is movably connected to the upper end of the conveying pipe 14, and the outer diameter of the lower end of the funnel 26 is smaller than the inner diameter of the feed inlet of the conveying pipe 14.

[0033] The clamp 20 serves as a connection and fixation mechanism, the support plate 21 serves as a support mechanism, the support column 22 serves as a support mechanism and facilitates the rotation of the movable plate 23, which also serves as a support mechanism. The round through hole 24 is used to place the funnel 26, and the arc-shaped through hole 25 facilitates the movement of the first arc-shaped limiting plate 27. The funnel 26 is used to pour filler into the conveying pipe 14, and the first arc-shaped limiting plate 27 and the second arc-shaped limiting plate 28 serve as limiting mechanisms.

[0034] Working principle:

[0035] Fix the clamp 20 to the upper section of the conveying pipe 14, so that the funnel 26 is located outside the conveying pipe 14. When it is necessary to add filler, push the first arc-shaped limiting plate 27 upward along the arc-shaped through hole 25 with your finger, and drive the movable plate 23 to rotate, which in turn drives the support column 22 below to rotate around the support plate 21. When the funnel 26 rotates to the top of the conveying pipe 14, release the first arc-shaped limiting plate 27. The first arc-shaped limiting plate 27 falls down, and the second arc-shaped limiting plate 28 adheres to the movable plate 23. At this time, the first arc-shaped limiting plate 27 wraps around the upper side of the conveying pipe 14. Pour the filler into the conveying pipe 14 through the funnel 26. After adding, rotate the funnel 26 away from the top of the conveying pipe 14. After all operations are completed, the funnel 26 in the round through hole 24 can be removed and cleaned.

[0036] This step prevents leakage when adding filler, reducing waste.

[0037] Please see Figure 3-4 This embodiment, based on the above embodiments, further includes:

[0038] The anti-fouling component includes a limiting insertion tube 30, a semi-circular insertion rod 31, and a semi-circular receiving box 32. The lower end of the limiting insertion tube 30 is fixed to the upper end of the support plate 21 and is located on both sides of the support column 22. The lower end of the semi-circular insertion rod 31 is inserted into the limiting insertion tube 30, and the semi-circular receiving box 32 is fixed to the upper end of the semi-circular insertion rod 31.

[0039] The anti-fouling component also includes a first arc groove 33 and a second arc groove 34. The first arc groove 33 is opened in the middle of the side of the semi-circular receiving box 32, and the second arc groove 34 is opened at one end of the side of the semi-circular receiving box 32.

[0040] The first arc-shaped groove 33 wraps around the outside of the support column 22, and the second arc-shaped groove 34 wraps around the outside of the conveying pipe 14;

[0041] The limiting insertion tube 30 and the semi-circular insertion rod 31 serve as a connection. The semi-circular receiving box 32 can receive the dripping filler. The first arc groove 33 provides rotation space for the support column 22, and the second arc groove 34 provides placement space for the delivery pipe 14.

[0042] Working principle:

[0043] Hold a semi-circular receiving box 32 in each hand, align the first arc groove 33 with the support column 22 and the second arc groove 34 with the delivery pipe 14. After the two semi-circular receiving boxes 32 are joined together, press down to insert the semi-circular insert rod 31 into the limiting insert tube 30. After the filling is finished, the funnel 26 rotates away from the delivery pipe 14, and the filling solution remaining on the inner wall of the funnel 26 slides into the semi-circular receiving box 32.

[0044] This step helps avoid contaminating the experimental environment.
