The utility model discloses a solution impurity filter device for chromatograph, which comprises a box body. A center shaft is installed through the rotation of a bearing at the top middle position of the box body, and a hopper is arranged on the top of the box body at the upper end of the center shaft. The bottom of the body is also provided with a pulley on the central shaft, and the pulley is connected with the drive motor at the top of the cabinet through the transmission belt.
The inside upper part of the box is provided with a shunt tube on the central axis. The inside of the box is provided with an impurity pushing plate at the lower end of the central axis. The impurity pushing plate is provided with a filter screen plate on the lower side. The upper side of the filter screen plate is on the impurity outlet. A meshed communicating pipe is connected to the other end of the meshed communicating pipe.
The utility model has the advantages of simple structure, impurity filtering of the solution entering the chromatograph, preventing the unmelted particles from entering the chromatograph and plugging the pipeline, causing the instrument to stop in trouble, guaranteeing the smooth progress of the detection work and satisfying the requirement of the high-throughput detection work. , And then improve work efficiency.
