Description

Technical Field

[0001] The utility model relates to the technical field of sampling detection, in particular to a sampling device for vegetable oil quality detection. Background Technique

[0002] Vegetable oil is made from plant kernels rich in oil. After pretreatment such as cleaning, dehulling, crushing, softening, rolling, and extrusion puffing, crude oil is obtained by mechanical pressing or solvent extraction, and then refined. When refining and storing vegetable oil, it is necessary to detect the quality of the produced vegetable oil. At this time, a sampling device is required to sample the vegetable oil multiple times to obtain a sufficient number of vegetable oil samples.

[0003] The existing Chinese utility model patent with the authorization announcement number of CN219434413U discloses a sampling mechanism for vegetable oil detection, including a barrel body and a sealed box. The sealed box is detachably installed in the inner cavity of the barrel body. A sampling pipe is fixedly installed on the bottom wall of the sealed box. A control mechanism cooperating with the barrel body is arranged on the side wall of the sealed box. The control mechanism includes a positioning component and a lifting component. The positioning component is located on the side wall of the sealed box and cooperates with the inner wall of the barrel body. The lifting component is located on the outer side wall of the barrel body and cooperates with the positioning component. A sampling component cooperating with the sampling pipe is arranged in the sealed box. In this utility model, by conveniently controlling the up and down movement of the sampling pipe in the barrel body, samples can be taken at different depths, solving the problem that vegetable oil at different depths in the storage tank cannot be sampled and the detection results have large errors.

[0004] Currently, the traditional sampling device has the following problems:

Among them, in order to ensure the accuracy of the detection, it is necessary to sample the vegetable oil samples at various positions. However, in the traditional scheme, when sampling the vegetable oil in the container, the vegetable oil samples at various positions generally complete the functions of sampling and conveying through a common pipeline. At this time, the inner wall of the pipeline is prone to adhering to the vegetable oil sampled last time and is prone to mixing with the vegetable oil sampled next time, affecting the accuracy of the vegetable oil detection data.

There are multiple diversion pipes 40. The stratified sampling mechanism 30 includes: a stratified base 301 arranged inside the storage tank 20; a sampling nozzle 302 installed inside the stratified base 301; and a sampling assembly 303 connected to the sampling nozzle 302 and installed inside the stratified base 301. There are multiple sampling assemblies 303, and the sampling assemblies 303 are connected to the diversion pipe 40.

[0031] In actual use of the above solution, the storage tank 20 stores vegetable oil. When performing the quality detection operation on the stored vegetable oil, each sampling assembly 303 is started to operate, so that the sampling nozzles 302 set at various positions and angles (heights) can extract the vegetable oil inside the storage tank 20 and transmit it to the corresponding sampling reagent bottles through the diversion pipe 40, completing the vegetable oil sampling operations at different positions and angles (bottom, middle, and top), improving the types of sampled vegetable oil samples, and ensuring the accuracy of the detection results when detecting the quality of vegetable oil. Among them, the stratified base 301 can be simply and conveniently placed inside the storage tank 20, and when it is necessary to clean the inner wall of the storage tank 20, it can be conveniently disassembled (using a crane, etc.).

[0032] In this solution, the design of the position of the stratified base 301 ensures that there is enough space inside the storage tank 20 for pouring vegetable oil and other equipment, suitable for various storage situations.
