Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, and particularly relates to a sampling device for the production and processing of mineral oil. Background Art

[0002] Mineral oil refers to hydrocarbons refined from petroleum, which is a high-purity mixture mainly composed of liquid alkanes and cycloalkanes. It does not belong to oil but is a mixture of liquid alkanes and cycloalkanes. Therefore, it is sometimes also called white oil or liquid paraffin. In chemistry, mineral oil usually refers to such a hydrocarbon mixture obtained by petroleum fractionation.

[0003] In the prior art, Chinese Patent Publication No. CN216669411U discloses a sampling device for the production and processing of waste mineral oil, including a sampling cylinder and an adjustment component. A conical cylinder is fixedly arranged at the bottom end of the sampling cylinder, an oil inlet pipe is fixedly arranged at the bottom of one side of the conical cylinder, a solenoid valve is fixedly arranged in the middle of the oil inlet pipe, a cylinder cover is arranged at the top end of the conical cylinder, and a connecting pipe is fixedly arranged in the middle of the cylinder cover. The beneficial effects of the utility model are as follows: By setting a forward and reverse motor, the connecting lead screw can be driven to rotate forward and backward. The connecting lead screw is threadedly connected with the connecting plate through a lead screw nut. Under the sliding cooperation of the guide rod and the guide seat, the connecting plate can be driven to move, so that the sampling cylinder can be driven to move to sample waste mineral oil at different positions in the oil tank; By setting the mounting column and the mounting seat, it is convenient to fixedly install the sampling device, and by setting the air extraction pipe, it is convenient to connect with a negative pressure device to facilitate the extraction of waste mineral oil into the sampling cylinder.

[0004] During use, this sampling device for the production and processing of waste mineral oil only relies on the sampling cylinder and the adjustment component to sample waste mineral oil at different positions in the oil tank. This sampling device for the production and processing of waste mineral oil does not set a stirring device, resulting in insufficient mixing between the components of the mineral oil in the oil tank, resulting in inaccurate detection results of the sampled mineral oil and poor use effects of this equipment. Therefore, it needs to be improved. Summary of the Utility Model
