[0043] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0044] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a solid phase extraction column 6 cleaning device, comprising: a cleaning box 1, a lifting assembly 2, a cleaning assembly 3, a cleaning rack 4 and a liquid supply assembly 5. A water receiving tray 11 is provided at the bottom of the cleaning box 1, and a plurality of mounting grooves 12 are provided on the side wall of the cleaning box 1. A lifting assembly 2 is provided corresponding to each mounting groove 12, and the movable end of the lifting assembly 2 is arranged toward the notch of the mounting groove 12. The cleaning assembly 3 is installed on the lifting assembly 2, and the cleaning head of the cleaning assembly 3 is extended into the solid phase extraction column 6 under the drive of the lifting assembly 2. The cleaning rack 4 is installed in the cleaning box 1, and the cleaning rack 4 is located directly above the water receiving tray 11. The liquid supply assembly 5 is arranged on one side of the cleaning box 1, and the liquid supply assembly 5 is connected to the cleaning assembly 3.

[0045] When in use, the solid phase extraction column 6 is installed on the cleaning rack 4. After installation, the lifting component 2 drives the cleaning component 3 to move downward, and during the movement, one end of the cleaning component 3 extends into the solid phase extraction column 6. During cleaning, the liquid supply component 5 provides cleaning agent to the cleaning component 3, and the cleaning component 3 cleans the inner wall of the solid phase extraction column 6. The used cleaning agent flows into the water receiving tray 11 below for centralized treatment to avoid environmental pollution.

[0046] The lifting component 2 described in this embodiment is one of a cylinder, a hydraulic cylinder, a linear motor or an electric push rod, among which the electric push rod is the best.

[0047] To facilitate cleaning, Figure 1 , Figure 2 and Figure 3 As shown, the cleaning assembly 3 includes: a mounting plate 31, a driving mechanism 33, a mounting rod 34, a liquid infusion channel and bristles 39. The mounting plate 31 is connected to the movable end of the lifting assembly 2, and a cleaning chamber 32 is arranged inside the mounting plate 31. The driving mechanism 33 is mounted at the bottom of the mounting plate 31, and the movable end of the driving mechanism 33 is arranged toward the water receiving tray 11. One end of the mounting rod 34 is connected to the movable end of the driving mechanism 33, and a liquid supply channel 35 is arranged inside the mounting rod 34. A water seepage hole 36 connected to the liquid supply channel 35 is arranged on the side wall of the mounting rod 34. One end of the delivery pipe 54 is connected to the cleaning chamber 32, and the other end is connected to the liquid supply channel 35 through a rotary joint 38. The bristles 39 are arranged along the axial direction of the mounting rod 34.

[0048] When in use, firstly, the mounting plate 31 is raised to a suitable position by the lifting assembly 2, so as to facilitate the placement of the solid phase extraction column into the cleaning box 1. After the solid phase extraction column 6 is mounted on the cleaning rack 4 of the cleaning box 1, the lifting assembly 2 is lowered, so that the mounting rod 34 equipped with the bristles 39 extends into the solid phase extraction column 6. Then the liquid supply assembly 5 provides the cleaning agent to the cleaning chamber 32 in the mounting plate 31, and the cleaning agent is sent into the liquid supply channel 35 of the mounting rod 34 through the liquid infusion pipe 37 connected to the cleaning chamber, and then the cleaning agent is transported into the solid phase extraction column 6 through the water seepage hole 36 connected to the liquid supply channel 35. When the cleaning agent enters the solid phase extraction column 6, the driving mechanism 33 drives the mounting rod 34 to rotate, and the mounting rod 34 drives the bristles 39 to clean the inner wall of the solid phase extraction column 6 during the rotation process.

[0049] The driving mechanism 33 in this embodiment is a motor.

[0050] In one embodiment, if Figure 1 As shown, in order to facilitate the positioning of the solid phase extraction column 6, a plurality of limiting grooves 41 for limiting the solid phase extraction column 6 are provided on the cleaning rack 4, and a through hole 42 matching the outer diameter of the solid phase extraction column 6 is provided at the bottom of the limiting groove 41. A driving mechanism 33, a mounting rod 34 and bristles 39 are separately provided on the mounting plate 31 corresponding to each limiting groove 41.

[0051] In one embodiment, if Figure 1 and Figure 2As shown, the liquid supply assembly 5 includes: a liquid distribution box 51, an ultrasonic mixer 52, a delivery pump 53 and a delivery pipeline 54. The liquid distribution box 51 is arranged on one side of the cleaning box 1. The ultrasonic mixer 52 and the delivery pump 53 are both installed in the liquid distribution box 51. One end of the delivery pipeline 54 is connected to the delivery pump 53, and the other end is connected to the cleaning chamber 32 in the mounting plate 31.

[0052] When in use, the cleaning agent and water enter the liquid distribution box 51, and then are mixed evenly by the ultrasonic mixer 52 in the liquid distribution box 51. The mixed agent is sent into the cleaning chamber 32 through the delivery pump 53 and the delivery pipe 54 connected to the delivery pump 53.

[0053] In one embodiment, in order to facilitate the installation plate 31 during the lifting process, the delivery pipe 54 has a surplus to make way during the lifting, so the delivery pipe 54 is a corrugated pipe.

[0054] In one embodiment, in order to prevent the cleaning agent from being thrown out of the water receiving tray 11 during the cleaning process, after the solid phase extraction column 6 is fixed on the cleaning rack 4 , the lowest point of the bottom of the solid phase extraction column 6 is located in the water receiving tray 11 .
