Detailed Description

As shown in fig. 1-3, a chromatographic column inner tube cleaning device comprises a cleaning box 1, wherein a concave support 2 is arranged in the cleaning box 1, a rotating seat 3 is arranged at the upper end of a vertical section of the concave support 2, a rotating shaft is arranged on the rotating seat 3, swing concave pieces 5 are respectively arranged at the inner side ends of the rotating shaft, and a swing motor 4 is connected to one rotating shaft.

The swing concave piece 5 is rotatably provided with a rotating rod 6, and the middle part of the rotating rod 6 is provided with a rotating cap 60. The two ends of the rotating rod 6 are respectively provided with a screw rod 61, the screw threads of the screw rods 61 are opposite in rotation direction, the screw rods 61 positioned at the same end are in threaded connection with an end top plate 62, and the end top plate 62 is provided with a through hole 64.

The middle pipe 73 is penetrated in the perforation 64, the middle position of the middle pipe 73 is closed, a flushing hole 74 is formed in the periphery of the middle pipe 73, rubber plugs 7 are sleeved at two ends of the middle pipe 73, a top plate 70 is arranged at the outer side end of each rubber plug 7, a plurality of stress pieces 71 are arranged on the top plate 70, and the stress pieces 71 are located on the inner side of the end top plate 62 and are clung to the inner wall of the end top plate 62.
