Description

Technical Field

[0001] This utility model belongs to the field of chemical sampling technology, specifically relating to a portable hot oil sampling water cooler suitable for hot oil sampling and analysis in industrial production. Background Technology

[0002] In industries such as petroleum and chemical engineering, it is frequently necessary to sample and analyze high-temperature oil products. Existing sampling equipment is often large, complex to operate, and has inadequate cooling. The high-temperature oil comes into direct contact with the external environment, posing safety hazards such as burns to operators or equipment damage. For example, traditional water coolers require large external cooling systems, resulting in complex on-site layouts, low cooling efficiency, and sampling cycles exceeding 30 minutes. Furthermore, traditional hot oil sampling equipment is bulky, relies on fixed installations, and weighs over 20 kg, making it difficult to move to different work sites and hindering mobile operation, thus failing to meet the flexible sampling needs of industrial sites. Therefore, there is an urgent need for a portable, highly efficient, and cooled hot oil sampling device to meet the requirements for rapid and safe on-site sampling. Utility Model Content

[0014] Figure 1 This is a schematic diagram of the portable hot oil sampling water cooler of this utility model. Detailed Implementation

[0015] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0016] This embodiment proposes a portable hot oil sampling water cooler, the overall structure of which is as follows: Figure 1 As shown, it mainly includes a hot oil sampling chamber 1 and a cooling unit 5. The hot oil sampling chamber 1 is used to contain hot oil samples, with a compression fitting quick connector 2 at the hot oil inlet and a sampling valve 3 at the hot oil outlet. The cooling unit 5 includes water-cooled pipes surrounding the sampling chamber 1 and a housing located around the water-cooled pipes. The inlet and outlet of the water-cooled pipes are connected to circulating cooling water pipelines, and support legs 4 are installed at the bottom of the housing.

[0017] When using the portable hot oil sampling water cooler, high-temperature oil is injected into the hot oil sampling chamber 1 through the sampling tube via the hot oil inlet end. Cooling water is introduced into the water cooling pipe. The cooling water flows inside the shell and forms a counter-current heat exchange with the hot oil flowing in the hot oil sampling chamber, reducing the oil temperature to a safe temperature (40℃). The sampling valve 3 is then opened to complete the sampling at the hot oil outlet end.

[0018] Using the portable hot oil sampling water cooler of this utility model, the sampling time for a single sampling is reduced from 30 minutes to 8 minutes. After cooling, the oil temperature drops to below 45°C. At the same time, it can avoid the volatilization of light components in hot oil at high temperatures, ensuring the accuracy of sample analysis, and significantly reducing the risk of burns to operators.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
