Abstract

The invention discloses an automatic continuous sampling device which comprises a buffer container A, a buffer container B, a buffer container C, a sampling groove, a rotary platform and a CPU controller, wherein the buffer container A is communicated with the buffer container B through a liquid outlet pipe; a solenoid valve is arranged on the liquid outlet pipe; a liquid level sensor is mounted on the buffer container B; a hole is formed in the top of the sampling groove; a flow guidance hole is formed in the bottom of the sampling groove; the rotary platform is fixed in the center of bottom of the sampling groove; one side of the buffer container C is fixed on the output shaft of a stepping motor, and the other side thereof is hanged in the air; multiple sampling bottles are arranged at the bottom of the sampling groove; a magnetic sensor is arranged on the sampling groove; a magnetic element is arranged on the buffer container C; the buffer container B is communicated with the buffer container C through a pipeline; a water suction pump is arranged on the pipeline; a stepping motor controller, the magnetic sensor, the solenoid valve, the water suction pump and the liquid level sensor are electrically connected with the CPU controller. The automatic continuous sampling device is simple in structure, low in cost and high in degree of automation, can automatically and continuously take a sample during the production process and can also monitor the flow rate.

Description

technical field [0001] The invention relates to the technical field of chemical detection and control, in particular to an automatic continuous sampling device. Background technique [0002] At present, in various industrial fields such as water supply, food, and medicine, in order to ensure the product quality in the production process, it is necessary to use an automatic sampling device to perform real-time sampling of raw materials, semi-finished products, and finished products in the production process, and to test or test the samples. In case of abnormality in laboratory tests, etc., the production process can be adjusted in real time to ensure the stability and consistency of product quality. At present, there are also many automatic sampling devices in the market, but these automatic sampling devices require complex mechanical transmission devices, and have the problems of complex structure and high manufacturing cost. Contents of the invention [0003] In order to...
