Abstract
An improved positive-pressure sample conveying system mainly solves the problem that a ball valve in a pressure relief device is complex in structure and high in fault rate and equipment is poor in stability rate and incapable of realizing direct bidirectional transferring of sample boxes in the prior art. The improved positive-pressure sample conveying system comprises a pipeline, pressure relief devices, exhaust devices, transceiving devices, a sample box and air supply devices. Each pressure relief device comprises an electromagnetic control butterfly valve, a photoelectric switch and a silencer. The sending section transmits the sample box through one transceiving device by the aid of high-pressure airflow, the sample box moves in the pipeline at high speed and is detected when passing through each photoelectric switch, the pressure relief devices and the exhaust devices are operated, and the high-pressure airflow escapes via the pressure relief devices resulting in sharp decrease of air pressure in the pipeline; at the same time, the exhaust devices have exhaust ports closed, resulting in that an enclosed space is formed between the sample box and the terminal of the pipeline, high-low pressure difference is formed between the front and the back of the sample box, and the sample box is buffered to be decelerated and falls into a receiving device of the receiving section.
