Description

Technical Field

[0001] This utility model relates to the field of oil processing, and in particular to a special oil-dissolving device for oil production. Background Technology

[0002] Early oil-dissolving equipment for oil production belonged to the oil processing field and mainly consisted of a heating device, an oil-dissolving container, and a temperature control device. During operation, the oil raw material was first put into the oil-dissolving container through the feed inlet, then the heating device was started, the temperature control device monitored the temperature in real time, and the stirring device worked simultaneously to ensure that the raw material was heated evenly and melted faster. After the oil was completely melted, the discharge outlet was opened to transport it to the next production process. After completing one oil-dissolving operation, the equipment needed to be cleaned and maintained.

[0003] Early specialized oil-dissolving devices for oil production consisted of a heating chamber, a stirrer, an oil storage tank, and inlet and outlet pipes. The heating chamber was heated by an electric heating wire, and the stirrer was a paddle type. During operation, it heated and stirred solid oils, which were then melted and flowed into the oil storage tank for output. Due to the high energy consumption of electric heating wires and the low efficiency of paddle stirring, as well as the lack of a separation device, there were problems such as low heating efficiency, uneven stirring, and incomplete separation of impurities and solid particles. Existing devices use electromagnetic induction and infrared combined heating to improve heating efficiency, and multi-axis, multi-angle stirrers solve the problem of insufficient stirring. However, existing devices still have the problem of not being able to accurately separate impurities and solid particles of different shapes and complex properties in the oil separation stage.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a special oil-dissolving device for oil production, including a base 1, which is the load-bearing structure of the device. A support frame 3 is fixedly connected to the middle of the inner wall of the base 1. The support frame 3 is used to fix a servo motor 4. The servo motor 4 is fixedly connected to the top of the outer wall of the support frame 3. The servo motor 4 drives the feed shaft 5 to rotate. The output end of the servo motor 4 is fixedly connected to the feed shaft 5. Liquid oil enters the top of the inner wall of the feed shaft 5. At the same time, the feed shaft 5 drives the conical plate 7 to rotate. Multiple square grooves 6 are opened at the bottom of the outer wall of the feed shaft 5. Liquid oil flows out through the square grooves 6. Multiple conical plates 7 are fixedly connected to the middle of the outer wall of the feed shaft 5. The rotation of the conical plates 7 causes impurities in the liquid oil to move outward centrifugally. Multiple square grooves 8 are opened at the top of the outer wall of the conical plates 7. After centrifugal separation, the high-pressure liquid oil... The grease moves upward through the square groove 8. The outer wall of the base 1 is fixedly connected to the top of the outer shell 13. The outer shell 13 is used to protect the device and fix the hollow cover 12. The inner wall of the outer shell 13 is fixedly connected to the top of the hollow cover 12. The hollow cover 12 is used to collect the high-pressure liquid grease after centrifugation. The outer wall of the hollow cover 12 is fixedly connected to the bottom of the upper inner shell 9. The upper inner shell 9 and the lower inner shell 11 are used to restrict the grease and guide impurities to gather in the waste ring 10 under centrifugal motion. The rear side of the outer wall of the hollow cover 12 is connected to the discharge pipe 28. The inner wall of the hollow cover 12 is rotatably connected to the outer wall of the feed shaft 5. The outer wall of the upper inner shell 9 is fixedly connected to the bottom of the outer wall of the waste ring 9. The bottom of the waste ring 10 is fixedly connected to the bottom of the waste ring 10. The inner wall of the feed shaft 5 is provided with a pre-processing mechanism 2. The pre-processing mechanism 2 is used for the initial pre-treatment of solid grease, changing it from solid to liquid.

[0032] Specifically, the high-pressure liquid grease enters the chamber consisting of the upper inner shell 9, the waste ring 10, and the lower inner shell 11 through the feed shaft 5 and the square groove 6. Under pressure, it moves towards the inner wall of the hollow cover 12. During the movement, the liquid grease passes through the conical plate 7, and the servo motor 4 drives the feed shaft 5 to rotate. The feed shaft 5 drives the conical plate 7 to rotate, causing the liquid grease to perform centrifugal motion in the horizontal direction. Among them, impurities and fixed particles gather towards the outer wall of the waste ring 10. The purified liquid grease moves through the square groove 8 under pressure towards the inner wall of the hollow cover 12 and is finally discharged through the discharge pipe 28.

[0033] Reference Figure 2 , Figure 3 and Figure 4 The pre-processing mechanism 2 includes a first conduit 201, one end of which is connected to a pressure tank 202, and the other end is connected to the inner wall of the hollow cover 12, allowing high-pressure liquid grease to enter the feed shaft 5 from the pressure tank 202. The outer wall of the first conduit 201 is connected to the top of the inner wall of the hollow cover 12, and the other end of the first conduit 201 is connected to the pressure tank 202, which pressurizes the liquid grease. The left side of the outer wall of the pressure tank 202 is connected to a second conduit 203, which is used to transport the liquid grease in the heating tank 204. The liquid grease is fed into the pressurizing tank 202. The other end of the conduit 203 is connected to the heating tank 204. Liquid grease is pre-added to the heating tank 204, and the solid grease after crushing is melted by heating with the liquid grease. A heating seat 205 is fixedly connected to the bottom of the inner wall of the heating tank 204. The heating seat 205 is used to fix the heating fins 206. The heating fins 206 are fixedly connected to the top of the outer wall of the heating seat 205. The heating fins 206 are composed of multiple fins, so that the liquid grease is heated more fully, thereby achieving an energy-saving effect.

[0034] Specifically, liquid grease is pre-added to the inner wall of the heating tank 204. The liquid grease is preheated by the heating seat 205, and then crushed solid grease is added. The preheated liquid grease heats the solid grease to melt it. Due to temperature and density, the solid grease floats on top of the liquid grease, the heated grease moves upward, and the melted grease, which is at a lower temperature, moves downward. A screen is installed on the front side of the second conduit 203 to prevent unmelted grease from entering the second conduit 203. The upward-moving liquid grease is transported to the pressure tank 202 through the second conduit 203. Pressure valves are installed on the left and top sides of the pressure tank 202. The pressure tank 202 is then pressurized and transported to the feed shaft 5 through the first conduit 201.

[0035] Reference Figure 1 , Figure 2 and Figure 4The outer wall of the base 1 is rotatably connected to diagonal braces 14 on all four sides. Four sliding mechanisms are rotatably connected to the outer wall of the base 1. Each sliding mechanism includes a diagonal brace 14, a roller 15, and a square groove 16. The diagonal brace 14 controls the contact between the roller 15 and the ground. Rollers 15 are rotatably connected to the bottom of the outer wall of the base 1. Multiple square grooves 16 are formed on the top of the outer wall of the roller 15. The diagonal brace 14 engages with the square grooves 16. The roller 15 contacts the ground when the diagonal brace 14 engages with the square groove 16 closest to the center of the base 1, and does not contact the ground when engaged with the square groove 16 furthest from the center of the base 1. An annular wall 17 is fixedly connected to the top of the inner wall of the heating tank 204. The annular wall 17 and the spiral bottom plate 19 form a crushing container. The top of the annular wall 17 is fixedly connected to the crusher 18, which crushes the solid fat in the container. The bottom of the inner wall of the annular wall 17 is fixedly connected to the spiral bottom plate 19, which simultaneously guides the solid fat of appropriate size to slide into the heating tank 204. The rear side of the discharge pipe 28 is connected to the ball valve 20, which is used to control the flow of purified liquid fat in the discharge pipe 28 to the storage tank 25 and the sampling pipe 21. The bottom of the outer wall of the ball valve 20 is connected to the storage tank 25, which is used as a storage device. The rear side of the outer wall of the ball valve 20 is connected to the sampling pipe 21, which is used to sample and inspect the quality of the purified liquid fat.

[0036] Specifically, the outer wall of the base 1 is provided with four sliding mechanisms. When the sliding mechanism is engaged with the square groove 16 near the center of the base 1 via the diagonal brace 14, the corresponding roller 15 contacts the ground. When the front and rear rollers 15 are in contact with the ground, they can move back and forth, and when the left and right rollers 15 are in contact with the ground, they can move left and right. Solid oil is crushed by the crusher 18 and screened by the spiral bottom plate 19 and guided to slide into the heating tank 204. Oversized particles cannot slide down and are further crushed by the crusher 18. The purified liquid oil is introduced into the storage tank 25 through the discharge pipe 28. When testing is required, the ball valve 20 is turned so that the purified liquid oil flows directly out from the sampling pipe 21.

[0037] Reference Figure 2 , Figure 4 and Figure 5The bottom of the outer wall of the storage tank 25 is connected to the drain valve 22. The drain valve 22 is used to quickly drain the liquid fat in the tank in case of emergency. The drain valve 22 is connected to the drain pipe 23 on the back side. The drain pipe 23 is used to discharge the drained liquid fat. The inner wall of the waste ring 10 is provided with multiple waste boxes 24. The waste boxes 24 are engaged with the waste ring 10. The waste boxes 24 are used to collect the impurities and solid particles accumulated at the waste ring 10. When the accumulation reaches a certain level, the waste boxes 24 are replaced regularly to clean up the accumulated impurities and solid particles. The top of the inner wall of the outer shell 13 is fixedly connected to the upper sound-absorbing cotton 26, and the bottom of the inner wall of the outer shell 13 is fixedly connected to the lower sound-absorbing cotton 27. The upper sound-absorbing cotton 26 and the lower sound-absorbing cotton 27 are used to absorb the noise generated by the equipment during rotation.

[0038] Specifically, in the event of an emergency such as tank rupture or severe contamination, the drain valve 22 is opened to quickly drain the grease inside the tank through the drain pipe 23, reducing losses and hazards. When impurities and solid particles accumulate to a certain extent on the inner wall of the waste ring 10, the waste box 24 is replaced regularly to clean the impurities and solid particles. Sound-absorbing cotton 26 and lower sound-absorbing cotton 27 are fixedly connected to the upper and lower sides of the inner wall of the outer shell 13 to absorb the noise generated when the device rotates.

[0039] Working principle: High-pressure liquid grease enters the feed shaft 5 and enters the chamber composed of the upper inner shell 9, waste ring 10 and lower inner shell 11 through the square groove 6 set at the bottom of the inner wall of the feed shaft 5. Due to the pressure, it moves towards the inner wall of the hollow cover 12. During the movement, the servo motor 4 on the support frame 3 rotates, driving the feed shaft 5 and the conical plate 7 to rotate. The high-pressure liquid grease, impurities and solid particles are centrifuged in the horizontal direction under the drive of the conical plate 7. Finally, due to the differential speed during centrifugal movement, impurities and solid particles gather on the inner wall of the waste ring 10. The purified liquid grease passes through the square groove 8 and moves into the hollow cover 12. Finally, it is discharged through the discharge pipe 28. The base 1 and the inner wall of the outer shell 13 are the supporting structures of the device. The device removes impurities from the grease by differential centrifugation.

[0040] Furthermore, the solid fat is pre-treated by the pre-processing mechanism 2. Before the grease enters the feed shaft 5, liquid fat is added to the heating tank 204 and preheated by the heating fins 206 on the heating seat 205. Then, the solid fat to be melted is added, and the liquid fat heats and melts the solid fat. The solid fat will be suspended on the upper layer of the liquid fat. The melted liquid fat will move downwards due to its density and be fully heated by the multiple heating fins on the heating fins 206. Then it will move upwards, thereby achieving thermal circulation of the liquid grease. After the liquid oil level in the heating tank 204 reaches a certain height, it enters the second conduit 203 through the screen and is then transported to the pressurizing tank 202 for pressurization. After pressurization, it is introduced into the feed shaft 5 through the first conduit 201. The heating fins 206 increase the contact area, thereby making the heating more complete. The thermal circulation of the liquid grease reduces the grease transportation process, thereby reducing the energy consumption of the device.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
