Description

Technical Field

[0001] This utility model relates to the field of chemical testing technology, specifically to a liquid phase injection vial cleaning device. Background Technology

[0002] In recent years, liquid chromatography (LC) has been widely used in pharmaceutical research and development and product testing. The use and reliance on LC by various R&D and manufacturing companies has shown a significant upward trend, while the cost of LC vials has also increased considerably. To save costs, laboratories commonly reuse LC vials. Due to the large volume of LC vials used, they need to be repeatedly cleaned with water, washing buffer, or organic solvents before reuse. However, the purification tubing and water column used in laboratories are generally large, resulting in low water pressure, which is insufficient for effectively cleaning the small-capacity LC vials. Furthermore, traditional cleaning methods are labor-intensive, time-consuming, and time-consuming due to the large volume of LC vials used. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a liquid phase injection vial cleaning device. This cleaning device can effectively clean multiple injection vials at the same time. By using a high-pressure and thin water line, the impact force during cleaning is increased, which can directly and effectively clean the inside of the injection vials.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a liquid phase injection vial cleaning device, including a fixing part and a cleaning part;

[0005] The fixing part includes a U-shaped frame, and four support plates are symmetrically arranged at both ends of the U-shaped frame;

[0006] Multiple fixing rods are provided on the lower side wall of the loop-shaped frame through a detachable structure, and the multiple fixing rods are evenly distributed along the front and rear direction of the loop-shaped frame.

[0007] Each fixing rod is equipped with multiple clamping structures for fixing liquid phase injection vials, and they are evenly distributed along the length of the corresponding fixing rod.

[0008] The top plate is hinged to the upper part of the U-shaped frame. The lower surface of the top plate is provided with multiple placement grooves that are adapted to the bottom of the liquid phase injection vial. The number of placement grooves is the same as the number of clamping structures and they correspond one-to-one.

[0009] The cleaning unit is used to simultaneously clean multiple liquid phase injection vials that are fixed by the fixing unit.

[0010] Furthermore, the cleaning unit includes a water storage chamber;

[0011] The upper surface of the water storage chamber has multiple cone-shaped cleaning nozzles, and the number of the multiple cleaning nozzles is the same as the number of multiple clamping structures and corresponds one-to-one.

[0012] A handle is provided at the lower end of the water storage chamber, and the handle has a hollow structure inside.

[0013] A water inlet pipe is provided at the lower end of the water storage chamber. One end of the water inlet pipe is located at the lower end of the water storage chamber and is connected to the interior of the water storage chamber. The other end of the water inlet pipe passes through the interior of the handle and is connected to a booster water pump.

[0014] The inlet of the booster pump is connected to the outlet of the purified water via a pipeline.

[0015] Furthermore, the clamping structure employs a fixed clamp;

[0016] The fixing clamp includes two arc-shaped clamps, and each end of the two arc-shaped clamps is provided with a bent operating plate, and the bent parts of the two operating plates are movably connected.

[0039] like Figure 1-7 As shown, the liquid chromatography vial 13 cleaning device includes a fixing part and a cleaning part;

[0040] The fixing part includes a U-shaped frame 1, and four support plates 2 are symmetrically arranged at both ends of the U-shaped frame 1. The four support plates 2 are used to place the entire fixing part on the cleaning pool.

[0041] Multiple fixing rods 3 are provided on the lower side wall of the U-shaped frame 1 through a detachable structure, and the multiple fixing rods 3 are evenly distributed along the front and rear direction of the U-shaped frame 1.

[0042] Each fixing rod 3 is equipped with multiple clamping structures 4 for fixing liquid phase injection vials 13, which are evenly distributed along the length of the corresponding fixing rod 3. The clamping structures 4 are used to fix the liquid phase injection vials 13 in an inverted manner on the fixing rod 3. The detachable structure facilitates the removal and installation of the fixing rod 3. Since the liquid phase injection vials 13 with small capacity are also very small, it is inconvenient to operate when directly fixing the liquid phase injection vials 13. The fixing rod 3 can be removed, which provides more operating space and makes it easier to clamp multiple liquid phase injection vials 13 through the clamping structures 4. After multiple liquid phase injection vials 13 are clamped, the fixing rod 3 can be installed on the U-shaped frame 1.

[0043] A top plate 5 is hinged to the top of the U-shaped frame 1. The lower surface of the top plate 5 is provided with a plurality of placement grooves 6 that are adapted to the bottom of the liquid phase injection vial 13. The number of placement grooves 6 is the same as the number of clamping structures 4 and corresponds one-to-one. That is, after the liquid phase injection vial 13 is clamped in the clamping structure 4, the bottom of the liquid phase injection vial 13 is located in the corresponding placement groove 6 and in contact with the bottom of the placement groove 6. Due to the weight of the top plate 5 itself, it can be ensured that the force of the high-pressure water flow will not push the vial away from the clamping structure 4 when the cleaning water pressure is increased.

[0044] The cleaning unit is used to simultaneously clean multiple liquid phase injection vials 13 that are clamped and fixed by the fixing unit.

[0045] like Figure 2 , Figure 5 As shown, in the above embodiment, preferably, the cleaning unit includes a water storage chamber 7;

[0046] The upper surface of the water storage chamber 7 has multiple conical cleaning nozzles 8, all of which are interconnected with the interior of the water storage chamber 7. This conical design allows for the generation of a high-pressure water line that is both high and thin. The number of the multiple cleaning nozzles 8 is the same as the number of the multiple clamping structures 4 and corresponds one-to-one. In other words, the number of the multiple conical cleaning nozzles 8 is the same as the number of multiple liquid phase injection vials 13 and corresponds one-to-one. The upper end of each conical cleaning nozzle 8 extends into the mouth of the corresponding liquid phase injection vial 13. In addition, due to the conical design, it can also enter the mouth of small-capacity liquid phase injection vials 13 to achieve cleaning of small-capacity liquid phase injection vials 13.

[0047] The lower end of the water storage chamber 7 is provided with a handle 9, the handle 9 having a hollow structure inside, which makes it easy to hold the water storage chamber 7.

[0048] A water inlet pipe 10 is provided at the lower end of the water storage chamber 7. One end of the water inlet pipe 10 is located at the lower end of the water storage chamber 7 and is connected to the interior of the water storage chamber 7. The other end of the water inlet pipe 10 passes through the interior of the handle 9 and is connected to a booster water pump 11.

[0049] The inlet of the booster pump 11 is connected to the outlet of the purified water through a pipeline. The booster pump 11 applies pressure to the purified water and pumps it into the water storage chamber 7, filling the water storage chamber 7 with pressurized purified water. Then, the purified water is sprayed out through multiple cone-shaped cleaning nozzles 8 to clean multiple liquid phase injection vials 13. The booster pump 11 can further increase the pressure of the high-pressure water line. When adjusting, the pressure can be adjusted by turning the adjustment knob or screw on the pressure switch on the booster pump 11 according to the actual needs.

[0050] like Figure 3 , Figure 7 As shown, in this embodiment, preferably, the clamping structure 4 is a fixed clamp;

[0051] The fixing clamp includes two arc-shaped clamping plates 401. Each end of the two arc-shaped clamping plates 401 is provided with a bent operating plate 402. The bent parts of the two operating plates 402 are movably connected, generally by a rotating shaft. One end of the rotating shaft extends and is fixed to the corresponding fixing rod 3, so as to fix the clamping structure 4 and open and close the two arc-shaped clamping plates 401. The working principle is similar to that of existing clamps.

[0052] A torsion spring 403 is provided between the two operating plates 402, which can be used to continuously clamp the liquid phase injection vial 13.

[0053] In this embodiment, preferably, all clamping structures 4 are made of waterproof materials, such as plastic, which can effectively extend their service life.

[0054] In this embodiment, preferably, an anti-slip protective pad is provided on the inner sidewall of the two arc-shaped clamps 401. This can increase the friction between the liquid chromatography vial 13 and the arc-shaped clamps 401, making the liquid chromatography vial 13 more stable, and can also prevent the arc-shaped clamps 401 from scratching the liquid chromatography vial 13.

[0055] like Figure 3 , Figure 4 As shown, in this embodiment, preferably, the detachable structure includes mounting grooves 12 provided on the left and right side walls of the U-shaped frame 1;

[0056] Each mounting groove 12 is embedded with a first strong magnet, and each fixing rod 3 is embedded with a second strong magnet at both ends (not shown in the figure). The two second strong magnets correspond one-to-one with the two first strong magnets and their magnetic poles are opposite. The fixing rod 3 is installed and removed by magnetic attraction, which is simple and easy to operate.

[0057] like Figure 1 As shown in this embodiment, preferably, all four support plates 2 are retractable support plates 2, which can better adapt to cleaning pools of different sizes.

[0058] like Figure 3 As shown, in this embodiment, preferably, the number of the plurality of fixing rods 3 is five; the number of the plurality of clamping structures 4 provided on each fixing rod 3 is eight, so that forty liquid phase injection vials 13 can be cleaned at one time, which meets the need for a large number of liquid phase injection vials 13.

[0059] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
