For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0026] Please refer to the attached Figure 1 To Attachment Figure 4 The utility model describes a precise measuring device for particle size distribution of solid paraffin wax.

[0027] At present, when the existing technology measures the particle size distribution of paraffin, the liquid paraffin may solidify and segregate due to temperature changes during transportation, affecting the accuracy of the detection results. At the same time, bubbles may be mixed in the liquid paraffin, affecting the accuracy of the detection structure.

[0028] Therefore, the measuring device includes a sample beaker 1 containing a liquefied paraffin sample 11 to be tested and a plunger pump 4. The sample beaker 1 is provided with a heating tube 12, which is inserted into the liquefied paraffin sample 11 to be tested for heat preservation and heating. The heating tube 12 is provided with a high temperature resistant particle size sensor 3 to measure the particle size distribution of the liquefied paraffin sample 11 to be tested. The plunger pump 4 is provided with an inlet end and an outlet end. The inlet end of the plunger pump 4 is connected to the end of the heating tube 12 away from the sample beaker 1, and the outlet end of the plunger pump 4 discharges the paraffin waste liquid 43; the heating tube 12 is inserted into the liquefied paraffin sample 11 to be tested for heat preservation and heating, and the liquefied paraffin sample 11 to be tested is heated and heated. When the liquefied paraffin sample 11 to be tested flows toward the high temperature resistant particle size sensor 3, it is still transported through the heating conduit 12, so as to avoid solidification and segregation during the transportation of the liquefied paraffin sample 11 to be tested, thereby ensuring the effectiveness and reliability of the test result; by setting the plunger pump 4, the liquefied paraffin sample 11 to be tested is sucked into the plunger pump 4 through the heating conduit 12, and negative pressure is provided to the liquefied paraffin sample 11 to be tested, so that the liquefied paraffin sample 11 to be tested can be measured by the high temperature resistant particle size sensor 3; by setting the high temperature resistant particle size sensor 3, there will be no zero point drift of the electronic components due to temperature changes during the measurement process, and the sensor has very good high temperature adaptability.

[0029] Preferably, the liquefied paraffin sample 11 to be tested needs to be heated and melted into a liquid state before being placed in the sample beaker 1. In other embodiments of the utility model, the liquefied paraffin sample 11 to be tested may be solid when placed in the sample beaker 1, and the liquefied paraffin sample 11 to be tested is heated into a liquid state by the heating tube 12.

[0030] Preferably, the plunger pump 4 is driven by a screw motor 41. In other embodiments of the utility model, it can also be driven by other motors as long as the plunger pump 4 can be started.

[0031] The device also includes a pressure cabin 2, and the sample beaker 1 is located in the pressure cabin 2. The pressure cabin 2 is provided with an opening, and the pressure cabin 2 is detachably connected to a hatch cover 21 through the opening. The sample beaker 1 is placed on the hatch cover 21.

By providing the electromagnetic stirrer 22, the solid particles are evenly suspended in the solution. In other embodiments of the utility model, other stirrers can also be selected as long as they can ensure that the solid particles are evenly suspended in the solution.

[0033] A heat insulating pad 23 is provided between the hatch 21 and the sample beaker 1. The heat insulating pad 23 is provided to avoid heat exchange and to minimize the phase change of liquid paraffin during measurement.

[0034] The pressure chamber 2 is connected to an air pipe 24, and one end of the air pipe 24 away from the pressure chamber 2 is connected to an air compressor 26. The air compressor 26 first applies negative pressure and then positive pressure to the pressure chamber 2 to eliminate bubbles in the liquefied paraffin sample 11 to be tested. By setting the air compressor 26, the air compressor 26 applies negative pressure to the pressure chamber 2 through the air pipe 24, thereby sucking out larger bubbles in the liquefied paraffin sample 11 to be tested, and then the air compressor 26 applies positive pressure to crush smaller bubbles in the liquefied paraffin sample 11 to be tested, thereby eliminating bubbles mixed in the liquid paraffin solution to the greatest extent, thereby ensuring detection accuracy.

[0035] A clean air filter 25 is provided on the air pipe 24. By providing the clean air filter 25, the air is filtered.

[0036] The outlet end of the plunger pump 4 is connected to a drainage conduit 42 , and one end of the drainage conduit 42 away from the plunger pump 4 is provided with a waste liquid beaker 44 for containing the paraffin waste liquid 43 discharged from the drainage conduit 42 .

[0037] The drainage conduit 42, the plunger pump 4 and the high temperature resistant particle size sensor 3 are all covered with a heating jacket 31. By setting the heating jacket 31, the stability of temperature control can be ensured and energy loss can be reduced. The outside of the heating jacket 31 is wrapped with a layer of flame retardant insulation cotton.

The first temperature measuring resistor 5, the second temperature measuring resistor 51, the third temperature measuring resistor 52 and the fourth temperature measuring resistor 53 are all electrically connected to the device controller 6. According to the feedback signals of the first temperature measuring resistor 5, the second temperature measuring resistor 51, the third temperature measuring resistor 52 and the fourth temperature measuring resistor 53, the temperature fluctuation range can be reduced quickly and linearly, and the display control is performed by the device controller 6.

[0039] An electronic thermometer 13 is connected to the pressure chamber 2. The electronic thermometer 13 is inserted into the liquefied paraffin sample 11 to be tested. The electronic thermometer 13 is electrically connected to the device controller 6. By setting the electronic thermometer 13, its temperature change is detected in real time, and the device controller 6 displays and controls it.

[0040] It should be noted that, except for manually adding the liquefied paraffin sample 11 to be tested into the sample beaker 1, the entire detection process can be automatically operated by the device controller 6, and all data during the operation are displayed in real time on the screen of the device controller 6.
