Liquid sampling device

Abstract

The present invention belongs to the field of sampling and inspection devices and discloses a liquid sampling device. The device includes a shell (1) having a bottom opening and a sampling mechanism mounted in the shell (1); the shell (1) is provided with a power source (2) and a control unit (3) which is used for controlling the sampling mechanism; the sampling mechanism includes a retractable sampler (41), a pumping device (42), and a sample discharging pipe (43); the sampler (41) is used for expending out of the bottom opening of the shell (1) to sample liquids of different depths and different volumes according to instructions issued by the control unit (3); and the sampler (41) is communicated with the sample discharging pipe (43) through the pumping device (42). The liquid sampling device of the invention has a high automation degree and can assist in effectively reducing the labor intensity of operators, and reducing the number of operators.

Description

technical field [0001] The invention relates to the field of sampling inspection equipment, in particular to a liquid sampling equipment. Background technique [0002] During the production, storage and processing of vegetable oils and fats, in order to ensure product quality, sanitation and quality inspections are required. Due to the large quantity, sampling inspection has become an indispensable means to control the quality of original products. In sampling testing, it is necessary to take a representative sample from a specified layer or position, and to maintain the integrity of the sample before the sample is transferred to the sample container. [0003] At present, the sampling of edible vegetable oil is all manually operated, and the sampling needs to be repeatedly put down and raised several times to complete the sampling. The operation is complicated, time-consuming, low in efficiency, and labor-intensive. It requires the cooperation of multiple people to complete;...

Problems solved by technology

[0003] At present, the sampling of edible vegetable oil is all manually operated, and the sampling needs to be repeatedly put down and raised several times to complete the sampling. The operation is complicated, time-consuming, low in efficiency, and labor-intensive. It requires the cooperation of multiple people to complete; it cannot be completed in real time. Monitoring the position of the sample head, the position of the sample is not easy to grasp, and the representativeness of the sample is not enough, which makes the test report data not objective and fair, which affects the detection effect to a certain extent; at the same time, the oil attached to the sample rope is difficult to clean, The sample rope is easily entangled and knotted, and the equipment is inconvenient to carry; when the sample taken by the skewer is poured into the sample container, it is easy to splash on the outer surface of the container and other places, and the oil stain is difficult to remove

my country produces and imports a large amount of edible vegetable oil every year. The low efficiency, unfriendly working environment, and low degree of automation in the sampling process of edible vegetable oil seriously restrict the development of sampling inspection, which is a major bottleneck affecting the current sampling of edible vegetable oil.
