[0002] Heat transfer oil, also known as heat carrier oil or hot oil, is a special oil used for indirect heat transfer. It has the characteristics of uniform heating, accurate temperature control, the ability to generate high temperature under low vapor pressure, and good heat transfer effect. Heat transfer oil is widely used in heating equipment in petrochemical, synthetic fiber, rubber and plastic, papermaking and dyeing, food processing, metallurgical machinery, air conditioning and electrical industries.

[0003] During use, heat transfer oil will be affected by chemical reactions such as oxidation, thermal cracking, and thermal polymerization, which will lead to a decrease in oil performance and the generation of impurities such as asphaltene, gum, colloid, and sludge in the oil, which will affect the smooth flow of the oil circuit, reduce heat transfer efficiency, increase energy consumption, and even cause serious consequences such as oil circuit blockage, equipment damage, and safety accidents. Since the kinematic viscosity of heat transfer oil at room temperature is relatively low, the impurities it contains will further reduce the kinematic viscosity of the heat transfer oil, resulting in low efficiency of the impurity removal device and difficulty in meeting usage requirements.

DETAILED DESCRIPTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-3As shown, a heat transfer oil preparation impurity removal device comprises a base 1, a vertical rod 2 is arranged on one side of the base 1, a slide groove is provided on one side of the vertical rod 2, a screw rod 4 is rotatably connected inside the vertical rod 2, a slider 6 is slidably connected inside the slide groove, a threaded hole threadedly connected to the screw rod 4 is provided inside the slider 6, an extension rod 7 is arranged on one side of the slider 6, a heating part is arranged at one end of the extension rod 7, the heating part comprises a heating cylinder 8 fixedly connected to the extension rod 7, the lower end of the heating cylinder 8 is open, the upper end of the heating cylinder 8 is provided with a through hole, a placement cylinder 9 is arranged inside the heating cylinder 8, the upper end of the placement cylinder 9 is open, an electric heating tube 10 is arranged inside the placement cylinder 9, and the electric heating The heat pipe 10 enters into the placement tube 9 through the through hole at the upper end of the heating tube 8. Liquid heat-conducting medium is stored inside the placement tube 9. A spiral heat-conducting plate 11 is provided on the outer surface of the placement tube 9. The outer side surface of the heat-conducting plate 11 is sealed and connected to the inner surface of the heating tube 8. An electric pump 12 is provided on the outer surface of the heating tube 8. The electric pump 12 has an oil suction pipe 13 and an oil discharge pipe 14. One end of the oil discharge pipe 14 is through-connected to the upper end of the heating tube 8. A cover 15 is provided at the lower end of the heating tube 8. A detachable filter funnel 16 is provided at the lower end of the cover 15. A filter screen 17 is provided inside the filter funnel 16. An extension portion 18 is provided at the lower end of the filter funnel 16.

[0018] The base 1 plays a supporting role, so that the vertical pole 2 can remain upright. By arranging reinforcing plates 3 on both sides of the vertical pole 2, the supporting stability of the vertical pole 2 can be improved. The base 1 can also be used to place an oil storage barrel 24. The heat transfer oil that has been filtered and impurities removed enters the oil storage barrel 24, which is convenient for the storage and transportation of the heat transfer oil.

[0019] The rotation of the screw rod 4 can be directly controlled, or a knob 5 can be set on the top of the screw rod 4 to control the rotation of the screw rod 4. When the screw rod 4 in the slide groove of the vertical rod 2 rotates, the thread of the screw rod 4 can cooperate with the slider 6 to control the slider 6 to move up and down in the slide groove, and then the position height of the extension rod 7 can be controlled. The position height of the filter funnel 16 is controlled by the position height of the extension rod 7. Since the specifications of the oil storage barrels 24 are different, the position of the filter funnel 16 can be adjusted according to the heights of the different oil storage barrels 24, so that the heat transfer oil flowing through the filter funnel 16 can directly enter the oil storage barrel 24, and the filter funnel 16 can also limit the movement of the oil storage barrel 24 to prevent the heat transfer oil from flowing to the outer surface of the oil storage barrel 24 due to external collisions and other factors.

[0020] The liquid heat-conducting medium inside the placement cylinder 9 can be heat-conducting oil or other liquids with high thermal conductivity, which is used to transfer the heat generated by the electric heating rod to the placement cylinder 9, and transfer the heat to the heat-conducting sheet 11 through the placement cylinder 9. The heat-conducting oil to be filtered is transported to the upper end of the heating cylinder 8 through the oil discharge pipe 14 by the electric pump 12, and the heat-conducting oil flows downward along the spiral heat-conducting sheet 11. As the heat-conducting sheet 11 is heated, the temperature of the heat-conducting oil gradually increases, the viscosity of the heat-conducting oil decreases, and the flow speed is accelerated, which is convenient for increasing the rate at which the heat-conducting oil passes through the filter 17 and improving the processing efficiency of the heat-conducting oil. Taking one of the heat-conducting oils L-QB300 as an example, the kinematic viscosity at 40°C is 24.5mm 2 / s, and the kinematic viscosity at 100°C is 4.6 mm 2 / s, as the temperature increases, the kinematic viscosity of the heat transfer oil decreases significantly.

[0021] The cover shell 15 and the filter funnel 16 are connected by a locking assembly 25, so as to facilitate the disassembly of the cover shell 15 and the filter funnel 16 and to facilitate the removal of impurities on the filter net 17. The cover shell 15 and the filter funnel 16 can also be connected by threads to achieve quick disassembly and assembly of the two.

[0022] Working principle: When in use, place the oil storage barrel 24 on the base 1, and make the upper end opening of the oil storage barrel 24 be located directly below the filter funnel 16, then rotate the screw rod 4, and through the cooperation of the screw rod 4 and the slider 6, the height of the filter funnel 16 is lowered. When the lower end of the filter funnel 16 enters the upper end opening of the oil storage barrel 24, stop the rotation of the screw rod 4, and then add the electric heating tube 10 into the placement cylinder 9. The electric heating tube 10 heats the spiral heat conducting sheet 11 through the liquid heat conducting medium and the placement cylinder 9. When the heat conducting sheet 11 is heated for a certain period of time, the temperature of the heat conducting sheet 11 rises, and then one end of the oil suction pipe 13 is extended into the container to be passed through. The heat transfer oil is filtered into a container, and then the electric pump 12 is started. The electric pump 12 pumps the heat transfer oil in the container into the heating cylinder 8 through the oil suction pipe 13 and the oil discharge pipe 14. The heat transfer oil flows downward along the spiral heat transfer sheet 11. As the heat transfer sheet 11 continuously heats the heat transfer oil entering the heating cylinder 8, the temperature of the heat transfer oil gradually increases, the kinematic viscosity of the heat transfer oil decreases, and its viscosity also decreases, so that the heat transfer oil can pass through the filter screen 17 more quickly, and the impurities in the heat transfer oil remain on the filter screen 17. The filtered heat transfer oil enters the oil storage barrel 24 through the extension portion 18 at the lower end of the filter funnel 16, thereby realizing the removal and collection of the heat transfer oil.

[0023] When the electric pump 12 is working, the vibration generated can also be transmitted to the filter screen 17 through the heating cylinder 8, the cover 15 and the filter funnel 16, thereby further improving the efficiency of the heat transfer oil passing through the filter screen 17.

[0024] Furthermore, a guide tube 19 is provided at the inner bottom of the filter funnel 16. The upper end of the guide tube 19 is located below the filter screen 17, and the lower end of the guide tube 19 exceeds the lower end of the extension portion 18. The outer surface of the guide tube 19 is fixedly connected to the inner wall of the filter funnel 16 by a connecting rod 20. The guide tube 19 is a hollow thin-walled pipe. When the heat transfer oil in the filter funnel 16 flows downward from the extension portion 18 at the lower end of the filter funnel 16, part of the heat transfer oil flows downward directly from the guide tube 19, while most of the heat transfer oil located between the guide tube 19 and the extension portion 18 flows downward along the outer wall of the guide tube 19, so that the heat transfer oil gradually concentrates toward the center direction of the guide tube 19 during the downward flow process, thereby reducing the adhesion of the heat transfer oil to the outer surface of the extension portion 18. When the upper end opening of the oil storage barrel 24 is small, it can also prevent the heat transfer oil from overflowing outside the upper end opening of the oil storage barrel 24.

[0025] Furthermore, a positioning ring 21 is provided at the lower end of the cover shell 15 , and the outer side surface of the positioning ring 21 is arranged to fit the inner surface of the upper end of the filter funnel 16 . The positioning ring 21 facilitates the determination of the position of the filter funnel 16 , thereby improving the installation efficiency of the filter funnel 16 .

[0026] Furthermore, a protective cover 22 is provided on the outer surface of the extension portion 18, and the lower end of the protective cover 22 is flared. The lower end of the extension portion 18 is located between the upper and lower ends of the protective cover 22. The protective cover 22 is used to cover the upper end opening of the oil storage barrel 24 to reduce impurities in the air from entering the oil storage barrel 24.

[0027] Furthermore, one end of the oil suction pipe 13 is provided with a counterweight pipe 23 which is connected to the oil suction pipe 13. The counterweight pipe 23 is made of brass. The counterweight pipe 23 can make one end of the oil suction pipe 13 sink directly to the bottom of the container filled with heat transfer oil, so that the heat transfer oil in the container can be extracted more quickly and effectively.

[0028] The device can heat the heat transfer oil to increase the kinematic viscosity of the heat transfer oil, thereby improving its filtering efficiency, and can transmit the vibration generated by the electric pump 12 to the filter 17 to further improve the filtering and impurity removal efficiency of the heat transfer oil. At the same time, the device can also adjust the height position of the filter funnel 16 so that the device can be suitable for oil storage barrels 24 of various specifications, which is easy to use.
