Description

Technical Field

[0001] The utility model relates to the field of solid phase extraction, in particular to an auxiliary cleaning structure for solid phase extraction equipment. Background Art

[0002] Solid phase extraction is a sample pretreatment technology that has been developed since the mid-1980s. It is developed by combining liquid-solid extraction and liquid chromatography technology. It is mainly used for sample separation, purification and enrichment. The main purpose is to reduce sample matrix interference and improve detection sensitivity. After the solid phase extraction is completed, in order to avoid affecting the quality of subsequent extraction, the extraction disk needs to be cleaned by using a cleaning structure.

[0003] The Chinese patent with the announcement number CN212597370U discloses an auxiliary cleaning structure for solid phase extraction equipment. The auxiliary cleaning structure for solid phase extraction equipment applies pressure to the support plate and the circular extraction device through the first compression spring outside the primary telescopic rod when the transmission rod drives the second compression spring and the bottom cleaning plate to rotate to clean the circular extraction plate, and at the same time applies pressure to the bottom cleaning plate through the second compression spring outside the sliding rod, so as to ensure that when the bottom cleaning plate cleans the inner bottom of the circular extraction plate, the impurities can be completely removed, thereby improving the cleaning effect. However, there are certain disadvantages in the placement and installation of the extraction plate in the device. The cleaning component is located at the center position and the position is relatively fixed. It is difficult to remove the extraction plate from the top. It is necessary to manually rotate the screw by opening the side position of the protective box to achieve the removal, which easily leads to poor sealing of the protective box. When using water spray cleaning, water leaks from the side. At the same time, it is not conducive to the reasonable recycling of the cleaning water flow, and it is easy to cause waste of water resources.

[0004] Therefore, the utility model provides an auxiliary cleaning structure for solid phase extraction equipment to solve the above problems. Utility Model Content

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary cleaning structure for solid-phase extraction equipment, comprising a protective box, an extraction disk arranged inside the protective box, a cleaning component arranged in the protective box at a position above the extraction disk for cleaning the extraction disk, a placement disc arranged in the protective box at a position below the extraction disk for placing the extraction disk, a clamping component arranged on the placement disc for clamping the extraction disk, and a nozzle arranged at the top of the protective box for spraying and cleaning the extraction disk; when in use, the extraction disk is first placed on the placement disc, and then the extraction disk to be cleaned is clamped by using the clamping component, which is convenient for later cleaning. In the process of placing the extraction disk, in order to avoid certain disadvantages of the existing auxiliary cleaning structure for solid-phase extraction equipment when placing and installing the extraction disk, it is difficult to fix the extraction disk by manually turning the screw by opening the side position of the protective box, which easily leads to poor sealing of the protective box and causes water to leak from the side when spraying water for cleaning.

After cleaning, the control motor is turned off, and the electric telescopic rod is started to drive the cleaning assembly to move upward to the same horizontal position as the containing box. At this time, the electric push rod is started to drive the supporting plate box to move in the direction of the containing box until the entire cleaning assembly is driven to move into the containing box, so that the extraction plate is not convenient to be taken out from the top.

When the water is spraying, the adjusting semicircular plate is adjusted to the other side of the fixed semicircular plate through the rotating assembly to form a sealing circular plate to achieve reasonable sealing and prevent water from flowing out.
