Description

Technical Field

[0001] The utility model relates to the technical field of crude oil measurement, in particular to a sampler for measuring crude oil density. Background Art

[0002] The existing sampler for measuring crude oil density uses an oil pumping device to draw crude oil into a container and measure the density of the crude oil inside. However, when it is used, there is no stirring device in the container, the density of different components in the crude oil may be different, and stratification may occur inside the crude oil, which may cause a decrease in measurement accuracy. For example, a Chinese patent discloses an "oil sampler for measuring oil density", and its application number is "202121706175.6". This device includes a sampling barrel and a handle provided on the sampling barrel. A partition is provided in the sampling barrel, and the partition is sealed and connected to the sampling barrel. A sealed chamber is formed in the sampling barrel, a servo motor is arranged in the sealed chamber, a bearing is arranged on the partition, a threaded rod is arranged in the bearing, the output shaft of the servo motor is connected to the threaded rod, a movable block matching with the threaded rod is arranged on the threaded rod, and a through hole is arranged at the bottom of the sampling barrel corresponding to the movable block, so as to improve the sealing of the sampler when sampling petroleum and ensure that the petroleum in the barrel will not leak out. However, when it is used, the sampling barrel does not have a stirring device, and the heavy components in the petroleum may tend to settle, while the light components will float up, which will cause uneven density, thereby affecting the accuracy of the final density measurement result. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art, and provides a sampler for measuring the density of crude oil. The connecting rod is driven by a second motor to drive the stirring rod to rotate, so that the crude oil can be mixed evenly. Because the densities of different components in the crude oil may be different, and stratification may occur inside the crude oil, the densities of different components in the crude oil can be mixed evenly by stirring, and the stratification phenomenon can be reduced, thereby improving the measurement accuracy. The constant temperature plate can provide a stable heating source for heating, and the temperature of the crude oil in the sampler can be controlled. Since the density of crude oil is closely related to the temperature, the crude oil is heated to the target temperature to ensure that the measurement is performed under the same temperature conditions, thereby improving the consistency and accuracy of the measurement. The crude oil is pumped into the interior of the measuring box by a conveying device, and the density of the crude oil is measured by a density measuring instrument. The density value of the crude oil can be determined, so as to understand its composition and properties. This is very important for the oil industry, because different crude oils have different density ranges, which have an impact on production, processing and sales. By regularly measuring the density of crude oil, impurities, dissolved gases and other problems that may appear in the crude oil can be discovered, and timely measures can be taken to deal with them to ensure the quality and safety of the product.

The above components can prevent the user from dropping the wrist rope when using the sampler.

[0012] Beneficial Effects

[0013] 1. Compared with the prior art, the sampler for measuring crude oil density can mix the crude oil evenly by driving the connecting rod through the second motor to drive the stirring rod to rotate. Because the densities of different components in the crude oil may be different, and stratification may occur inside the crude oil, the densities of different components in the crude oil can be evenly mixed by stirring, reducing the stratification phenomenon, thereby improving the measurement accuracy. Moreover, the constant temperature plate can provide a stable heating source, and the temperature of the crude oil in the sampler can be controlled. Since the density of crude oil is closely related to the temperature, the crude oil is heated to the target temperature to ensure that the measurement is performed under the same temperature conditions, thereby improving the consistency and accuracy of the measurement.

[0014] 2. Compared with the existing technology, the sampler for measuring crude oil density uses a conveying device to draw crude oil into the interior of a measuring box, and measures the density of the crude oil through a density measuring instrument, so as to determine the density value of the crude oil and understand its composition and properties. This is very important for the oil industry, because different crude oils have different density ranges, which have an impact on production, processing and sales. In addition, by regularly measuring the density of crude oil, possible impurities, dissolved gases and other problems in the crude oil can be discovered, and timely measures can be taken to deal with them to ensure the quality and safety of the product.
