Description

Technical Field

[0001] The utility model relates to the technical field of solid phase extraction columns, in particular to a solid phase extraction filling device. Background Art

[0002] Solid phase extraction columns are mainly used for sample pretreatment of target compounds in various foods, agricultural and livestock products, environmental samples, and biological samples. Although the solid phase extraction columns available on the market are already filled with adsorbents, some merchants still provide empty column tubes to facilitate users to fill adsorbents according to their needs. Usually, the demand for such extraction columns is relatively small. When filling adsorbents according to demand, if the manufacturer is asked to process it on behalf of the user, the cost will inevitably increase; and there are also many problems with manual operation. For example, manual filling is not only inefficient, but also difficult to ensure the uniformity and tightness of the filling, resulting in unstable performance of the solid phase extraction column and affecting the reproducibility of the experimental results.

[0003] Therefore, a solid phase extraction filling device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1-2 The utility model provides a solid phase extraction filling device, comprising:

[0024] A shell 1, a material box 2 is fixedly connected to the shell 1, and the material box 2 is provided with a plurality of discharge holes. A first partition 3 and a second partition 4 are fixedly connected to the shell 1, and a feeding mechanism is slidably arranged between the first partition 3 and the second partition 4. A plurality of first through holes 5 are provided on the first partition 3, and the first through holes 5 are connected with the discharge holes. A plurality of second through holes 6 are provided on the second partition 4, and the first through holes 5 and the second through holes 6 are completely staggered.

[0025] The material receiving assembly includes a base 7, a mounting frame 8 is elastically arranged inside the base 7, a plurality of hollow column tubes 9 are placed on the mounting frame 8, a limited seat 10 is fixedly connected inside the outer shell 1, the limited seat 10 is adapted to the base 7, the limited seat 10 is located below the second through hole 6, and a plurality of vibration motors 11 are fixedly connected inside the mounting frame 8.

[0026] In the present device, the material box 2 is used to hold the adsorbent material in the solid phase extraction column, and the feeding mechanism is located between the first partition plate 3 and the second partition plate 4. The adsorbent in the material box 2 enters the feeding mechanism through the discharge hole and the first through hole 5, and the feeding mechanism then delivers the adsorbent material to the second through hole 6, and the adsorbent material falls through the second through hole 6. The base 7 is used to place the mounting frame 8. The adsorbent is injected into the empty column tube 9 to form a solid phase extraction column. The limiting seat 10 is used to limit the base 7. The limiting seat 10 has enclosures on three sides and a notch on one side. Pushing the base 7 into the limiting seat 10 can make the empty column tube 9 located below the second through hole 6. When the adsorbent falls, it can fall into the empty column tube 9. When the vibration motor 11 vibrates, it will drive the mounting frame 8 to vibrate, and the mounting frame 8 will drive the empty column tube 9 to vibrate, thereby causing the adsorbent inside the empty column tube 9 to vibrate, making the adsorbent in the empty column tube 9 more uniform and compact.

[0027] According to a further optimization scheme, a plurality of first springs 12 are fixedly connected to the inner side wall of the base 7, a first top plate 13 is fixedly connected to the first spring 12, a plurality of second springs 14 are fixedly connected to the inner bottom wall of the base 7, a second top plate 15 is fixedly connected to the second spring 14, and both the first top plate 13 and the second top plate 15 are in contact with the mounting frame 8.

[0028] The mounting frame 8 is inside the base 7 , and under the action of the first spring 12 and the second spring 14 , the vibration motor 11 can drive the mounting frame 8 to vibrate.

[0029] A further optimized solution is that the feeding mechanism includes a moving block 16, which is provided with a plurality of through holes 17. The moving block 16 is slidably arranged between the first partition 3 and the second partition 4. An electric telescopic rod 18 is fixedly connected to the outer shell 1, and the electric telescopic rod 18 is located between the first partition 3 and the second partition 4. The output end of the electric telescopic rod 18 is fixedly connected to the moving block 16.

[0030] The electric telescopic rod 18 drives the moving block 16 to move. When the through hole 17 on the moving block 16 moves to below the first through hole 5, the adsorbent material in the material box 2 will fall into the through hole 17. At this time, the second partition 4 will block the bottom of the first through hole 5. When the through hole 17 is full of material, under the action of the electric telescopic rod 18, the through hole 17 and the first through hole 5 are completely staggered. When the through hole 17 and the second through hole 6 gradually overlap, the adsorbent material will fall from the second through hole 6.

[0031] According to a further optimized solution, the mounting frame 8 includes a plurality of positioning holes, and the hollow column tubes 9 are placed in the positioning holes.

[0032] The positioning hole is convenient for inserting the empty column tube 9.

[0033] According to a further optimized solution, a plurality of funnels 19 are fixedly connected to the second partition plate 4 , and the funnels 19 are connected to the second through holes 6 .

[0034] The funnel 19 facilitates the adsorbent material to fall into the empty column tube 9 .

[0035] In a further optimized solution, the material box 2 is fixedly connected to the housing 1 via a connecting rod 20 .

[0036] The connecting rod 20 is used to increase the stability of the material box 2 .

[0037] The method of using the device is as follows: pour the adsorbent material into the material box 2, start the electric telescopic rod 18, and make the electric telescopic rod 18 drive the moving block 16 to move, so that the through hole 17 is aligned with the first through hole 5, so that the adsorbent material enters the through hole 17, and the second partition plate 4 will block the bottom of the first through hole 5. When the through hole 17 is full of material, under the action of the electric telescopic rod 18, the through hole 17 and the first through hole 5 are completely staggered. When the through hole 17 and the second through hole 6 gradually overlap, the adsorbent material will fall from the second through hole 6, and the funnel 19 facilitates the adsorbent material to fall into the empty column tube 9. When the adsorbent falls into the empty column tube 9 completely, the vibration motor 11 vibrates, driving the mounting frame 8 to vibrate, and the mounting frame 8 will drive the empty column tube 9 to vibrate, thereby causing the adsorbent inside the empty column tube 9 to vibrate, so that the adsorbent in the empty column tube 9 is more uniform and compact.
