Description

[0002] The pour point of oil products is a conditional indicator of low-temperature fluidity of crude oil, which is a temperature dividing point where the physical state of crude oil changes. The pour point refers to the lowest temperature at which the tested oil sample can maintain fluidity under specified conditions. The pour point is an important parameter for controlling the crude oil transportation temperature.

When the number of test samples is large, multiple samples need to be tested individually for multiple times, which is time-consuming and has low work efficiency. After the test, in order not to affect subsequent tests, the test tubes need to be cleaned one by one, and the process is relatively cumbersome. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-4 As shown, a rapid detection instrument for pour point of oil products comprises a detection box body 1, a detection instrument control panel 2 is installed at one side of the front end of the detection box body 1, and a detection component 3 is arranged inside the detection box body 1;

[0024] The detection assembly 3 includes a plurality of movable boxes 4, which are rotatably installed inside the detection box body 1 through a rotating shaft. An adjusting motor 13 is installed at an upper position on one side of the detection box body 1, and the driving shaft of the adjusting motor 13 passes through one side of the detection box body 1 and is connected to a transmission rod 15. A bevel gear set 16 is provided at the connection between the transmission rod 15 and the movable box 4, and the transmission rod 15 is meshedly connected to the movable box 4 through the bevel gear set 16. A detection test tube 5 is installed on the internal thread of the movable box 4, and a pour point detection probe 12 is installed at the center position of the inside of the detection test tube 5, a cleaning water pipe 8 is provided at the front position of the top end of the detection test tube 5, and a liquid adding tube 6 is provided at the rear position of the top end of the detection test tube 5, the top end of the liquid adding tube 6 is fixedly connected to a liquid adding head 7, and the top end of the liquid adding head 7 is threadedly connected to a sealing plug.

[0025] In this embodiment, a petroleum ether constant temperature liquid storage tank 10 is provided at the rear end of the detection box body 1, and a cleaning water pump 11 is installed on the top of the petroleum ether constant temperature liquid storage tank 10. The water suction port of the cleaning water pump 11 is connected to a suction pipe, and the suction pipe extends into the petroleum ether constant temperature liquid storage tank 10. The water outlet of the cleaning water pump 11 is connected to a delivery pipe 9, and the end of the delivery pipe 9 away from the cleaning water pump 11 is connected to a plurality of cleaning water pipes 8. By starting the cleaning water pump 11, the petroleum ether cleaning agent in the petroleum ether constant temperature liquid storage tank 10 is conveniently delivered to the detection test tube 5, thereby flushing the petroleum sample in the detection test tube 5, reducing the cumbersome steps during manual cleaning.

[0026] In this embodiment, semiconductor refrigeration sheet groups 14 are provided at the front and rear ends of the movable box 4. The cold end of the semiconductor refrigeration sheet group 14 matches the detection test tube 5. A heat dissipation aluminum bar is provided at the bottom end of the movable box 4, and the hot end of the semiconductor refrigeration sheet group 14 is connected to the heat dissipation aluminum bar through a heat conductive sheet. The semiconductor refrigeration sheet group 14 is powered on for cooling, which is convenient for temperature control. The semiconductor refrigeration sheet group 14 does not require any refrigerant, can work continuously, has no pollution source, and has no vibration and noise during operation. When the hot end dissipates heat well and the cold end is unloaded, the maximum temperature difference can be achieved within less than one minute of power-on.

[0027] In this embodiment, a cooling fan 17 matching the cooling aluminum row is provided at the bottom of the movable box 4, a temperature sensor is installed on the lower end side of the outer ring of the detection test tube 5, and a mica electric heating sheet element is provided on the upper end side of the outer ring of the detection test tube 5. By starting the cooling fan 17, the heat dissipation efficiency of the hot end of the semiconductor refrigeration sheet group 14 is accelerated to ensure the cooling stability of the semiconductor refrigeration sheet group 14.

[0028] In this embodiment, a drain pipe 18 is provided through the bottom end of the detection test tube 5, and a solenoid valve 19 is provided at the connection between the drain pipe 18 and the detection test tube 5. By opening the solenoid valve 19, the drain pipe 18 is connected to the bottom end of the detection test tube 5 for easy adjustment.

[0029] In this embodiment, a waste liquid collection box is provided at the lower part of the detection box body 1, and the end of the drain pipe 18 away from the detection test tube 5 extends into the waste liquid collection box. The waste liquid collection box facilitates the collection of the discharged waste liquid.

[0030] In this embodiment, a plurality of movable boxes 4 are arranged equidistantly in the detection box body 1, and the plurality of movable boxes 4 do not touch each other. The discharge pipe 18 and the delivery pipe 9 are both configured as telescopic hoses. The plurality of movable boxes 4 do not touch each other to avoid collision when tilted, and the telescopic hoses are configured to be stretched as the movable boxes 4 rotate.

[0031] It should be noted that the utility model is a rapid detection instrument for the pour point of oil products. When in use, first, the plugs on the multiple liquid adding heads 7 can be unscrewed as needed, and then the oil samples can be added into the multiple detection test tubes 5 through different liquid adding heads 7. After the oil samples are added, the pour points of the oil samples in the detection test tubes 5 can be detected by the detector control panel 2 and the pour point detection probe 12 according to the prior art, and the temperature in the detection test tubes 5 can be detected in real time by the temperature sensor, and then the semiconductor refrigeration chip group 14 can be controlled to perform refrigeration. Because the semiconductor refrigeration chip group 14 does not require any refrigerant, it can work continuously, has no pollution source, and has no vibration and noise when working. Moreover, the semiconductor refrigeration chip group 14 is a current transducing chip. By controlling the input current, high-precision temperature control can be achieved. At the same time, the thermal inertia of the semiconductor refrigeration chip group 14 is very small, and the cooling and heating speeds are fast. When the heat dissipation at the hot end is good and the cold end is unloaded, the maximum temperature difference can be achieved in less than one minute after power-on.

[0032] Therefore, when detecting the pour point of the petroleum sample, the preset minimum temperature can be controlled by the detector control panel 2 to reach a suitable value, and the temperature at the pour point detection probe 12 can be detected by the temperature sensor. When it reaches minus thirty degrees Celsius, the adjustment motor 13 is started, and the transmission rod 15 is driven to rotate by the adjustment motor 13. The transmission rod 15 is engaged and driven to drive the movable box 4 to rotate, thereby rotating the detection test tube 5, and the pour point detection probe 12 is used to detect whether the pour point has been reached. When the pour point is not detected, the detection test tube 5 is driven to rotate and reset by reversing the adjustment motor 13;

[0033] Then, according to the above steps, the temperature is lowered by two degrees Celsius and the test is performed again until the pour point of the sample is detected, so as to determine that the temperature at this time is the pour point temperature of the petroleum sample in the test tube 5. At the same time, after all the pour point detection probes 12 have completed the detection, all the test tubes 5 are tilted and maintained for sixty seconds by control, so as to further ensure that the petroleum sample in the test tube 5 does not flow, so as to ensure the detection accuracy;

[0034] At the same time, during the detection process, since the hot end of the semiconductor refrigeration sheet group 14 is connected to the heat dissipation aluminum row through the heat conductive sheet, and the heat dissipation aluminum row is provided with a heat dissipation fan 17, the heat dissipation fan 17 can be started to accelerate the heat dissipation efficiency of the hot end of the semiconductor refrigeration sheet group 14 to ensure the refrigeration stability of the semiconductor refrigeration sheet group 14;

[0035] When it is necessary to clean the sample in the test tube 5, the solenoid valve 19 can be opened to connect the drain pipe 18 with the bottom end of the test tube 5. Since the end of the drain pipe 18 away from the test tube 5 is connected to the waste liquid collection box, the waste liquid can be discharged into the waste liquid collection box. At the same time, when discharging, the mica electric heating plate element provided on the test tube 5 can be energized for auxiliary heating so that the petroleum sample can be melted.

[0036] At the same time, since a cleaning water pipe 8 is arranged inside the detection test tube 5, and one end of the cleaning water pipe 8 extending out of the detection test tube 5 is connected to the delivery pipe 9, and one end of the delivery pipe 9 away from the cleaning water pipe 8 is connected to the outlet of the cleaning water pump 11, so that during cleaning;

[0037] The cleaning water pump 11 can be started, and the petroleum ether cleaning agent in the petroleum ether constant temperature storage tank 10 can be added into the detection test tube 5 to flush the petroleum sample in the detection test tube 5. After cleaning, the cleaning water pump 11 can be closed and after all the waste liquid flows out, the solenoid valve 19 can be closed and the mica electric heating plate element can be powered off to complete the reset for subsequent use.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
