[0046] In the production process of lubricating oil, a blending tank is needed to fully blend the base oil and additives. Current blending tank designs typically only have a simple stirring shaft inside the tank for agitation. While the structure is simple, the lubricating oil is not blended evenly and thoroughly, resulting in a mediocre blending effect.

[0047] Therefore, this utility model proposes a lubricating oil mixing tank that can effectively improve the above-mentioned problems.

[0048] The following description, with reference to the accompanying drawings, describes a uniformly blended lubricating oil mixing tank according to an embodiment of the present invention.

[0049] Reference Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a uniformly blended lubricating oil mixing tank, comprising: a tank body 100, a stirring assembly, an air supply device 400, and a first circulation assembly 500.

[0050] The tank body 100 defines a mixing chamber 101. The tank body 100 is provided with an inlet pipe 105 and an outlet pipe 106 that communicate with the mixing chamber 101. The inlet pipe 105 is located at the top of the tank body 100 and can be used to add base oil and additives. The outlet pipe 106 is located at the bottom of the tank body 100 and is used to discharge the mixed lubricating oil. The outlet pipe 106 is provided with a switch valve to control its on / off state.

[0051] The stirring assembly includes a stirring section 200 and a driving section 300. The stirring section 200 is rotatably disposed in the tank 100 and is at least partially located in the mixing chamber 101 for stirring the lubricating oil in the mixing chamber 101. An airflow channel 201 is defined inside the stirring section 200. A plurality of air holes 202 are formed on the outer wall of the airflow channel 201. The air holes 202 are located in the mixing chamber 101 to connect the airflow channel 201 and the mixing chamber 101. The driving section 300 is connected to the stirring section 200 for driving the stirring section 200 to rotate. It should be noted that the lubricating oil mentioned herein refers to a mixture of base oil and additives.

[0052] The gas supply device 400 is connected to the stirring part 200. The gas supply device 400 is used to supply gas into the airflow channel 201 so that the gas can be delivered to the mixing chamber 101 through the air hole 202, thereby pneumatically stirring the lubricating oil in the mixing chamber 101.

[0053] The first circulation component 500 is connected to the tank 100. The first circulation component 500 is used to circulate and transport the lubricating oil in the mixing chamber 101. That is, the first circulation component 500 can extract the lubricating oil in the mixing chamber 101 and then transport it back to the mixing chamber 101 through the first circulation component 500, so that the lubricating oil in the mixing chamber 101 circulates.

[0054] The lubricating oil mixing tank of this utility model has a rotating stirring section 200, which can be used to stir the lubricating oil in the mixing chamber 101. By providing an airflow channel 201 and air holes 202 inside the stirring section 200, and by providing an air supply device 400 to supply air to the airflow channel 201, the lubricating oil in the mixing chamber 101 can also be pneumatically stirred. By providing a first circulation component 500 to circulate and transport the lubricating oil in the mixing chamber 101, the lubricating oil in the mixing chamber 101 can be made to flow fully. The combination of these three features can make the lubricating oil more thoroughly and evenly mixed, effectively improving the quality of the product.

[0055] It is conceivable that the feed pipe 105 can be left open to facilitate gas discharge.

[0056] Reference Figure 1 As shown, in some embodiments of this utility model, the first circulation component 500 includes a first circulation pump 510, an oil extraction pipe 520, and an oil return pipe 530. One end of the oil extraction pipe 520 is connected to the bottom end of the tank 100, and the other end is connected to the input end of the first circulation pump 510. One end of the oil return pipe 530 is connected to the top end of the tank 100, and the other end is connected to the output end of the first circulation pump 510. Specifically, the oil extraction pipe 520 is connected to the discharge pipe 106, and the connection point between the two is located above the switch valve. The oil return pipe 530 is connected to the feed pipe 105. In this way, the lubricating oil in each position in the mixing chamber 101 can be fully circulated.

[0057] It is conceivable that a filter screen, filter plate, or filter cylinder could be installed at the bottom of the discharge pipe 106 to filter the lubricating oil and remove impurities during the discharge process.

[0058] Reference Figure 1As shown, in some embodiments of this utility model, the tank 100 includes an inner tank 102 and an outer tank 103. A heating chamber 104 is defined between the inner tank 102 and the outer tank 103, surrounding the inner tank 102. A mixing chamber 101 is formed inside the inner tank 102. The outer tank 103 is provided with an inlet 107 and an outlet 108 communicating with the heating chamber 104. The inlet 107 is located at the top of the heating chamber 104, and the outlet 108 is located at the bottom of the heating chamber 104. The uniformly mixed lubricating oil mixing tank also includes a water tank 600 and a second circulation assembly 700. The water tank 600 contains a heating medium and a second heating part, which is used to heat the heating medium. The second circulation assembly 700 is connected between the water tank 600 and the tank 100, and is used to circulate and transport the heating medium between the water tank 600 and the heating chamber 104. By adopting the above-described structure, the mixing chamber 101 can be heated by the heating medium. Since the heating chamber 104 is distributed around the inner tank 102, the lubricating oil in the mixing chamber 101 can be heated evenly to improve the mixing effect of the lubricating oil.

[0059] It is conceivable that the second heating section can use an electric heater, which is a conventional technical method, so it will not be discussed in detail here.

[0060] It is conceivable that the heating medium could be water, oil, or other media that meet the requirements.

[0061] Based on the above embodiments, in some specific embodiments, refer to Figure 1 As shown, the second circulation assembly 700 includes a second circulation pump 710, an inlet pipe 720, and an outlet pipe 730. The second circulation pump 710 is installed in the water tank 600 and is used to pump the heating medium in the water tank 600. The two ends of the inlet pipe 720 are respectively connected to the output end of the second circulation pump 710 and the inlet 107. The two ends of the outlet pipe 730 are respectively connected to the water tank 600 and the outlet 108.

[0062] It is conceivable that flow valves can be installed on the inlet pipe 720 and the outlet pipe 730 to control the flow rate of the heating medium, thereby facilitating the adjustment of the heating temperature; of course, temperature control can also be achieved by controlling the power of the second heating unit; based on this, a temperature sensor can be installed in the mixing cavity 101, and the temperature sensor is electrically connected to the second heating unit.

[0063] Reference Figure 1 and Figure 2As shown, in some embodiments of this utility model, the stirring unit 200 includes a rotating shaft 203 and multiple sets of stirring rods 204. The rotating shaft 203 is vertically distributed and rotatably connected to the tank body 100; the multiple sets of stirring rods 204 are connected to the rotating shaft 203 and arranged vertically at intervals; wherein, the rotating shaft 203 and the stirring rods 204 are hollow and interconnected to form an airflow channel 201, and each set of stirring rods 204 is provided with an air hole 202, so that the lubricating oil can be pneumatically stirred at different heights, thereby improving the stirring effect.

[0064] It is conceivable that the rotating shaft 203 can be rotatably connected to the tank body 100 via a bearing, and a sealing structure is provided at the connection.

[0065] It is conceivable that a set of stirring rods 204 may include multiple stirring rods 204 arranged circumferentially along the rotating shaft 203, or a set of stirring rods 204 may include only one stirring rod 204.

[0066] Based on the above embodiments, in some specific embodiments, refer to Figure 1 As shown, the stirring rod 204 is arranged horizontally.

[0067] Based on the above embodiments, in some specific embodiments, refer to Figure 1 As shown, the drive unit 300 includes a drive motor, a pinion gear, and a gear. The drive motor is mounted on the top of the tank 100. The pinion gear is connected to the output shaft of the drive motor, and the gear is connected to the rotating shaft 203 and meshes with the pinion gear. In this way, the rotating shaft 203 is driven to rotate by the drive motor.

[0068] Based on the above embodiments, in some specific embodiments, refer to Figure 1 and Figure 2 As shown, the air hole 202 is set with its opening facing downwards. The advantage of this setting is that, on the one hand, the lubricating oil at the bottom of the mixing chamber 101 can flow fully, and on the other hand, it can effectively prevent the lubricating oil from entering the airflow channel 201 through the air hole 202.

[0069] Furthermore, the lower end face of the rotating shaft 203 is also provided with an air hole 202 to prevent lubricating oil from entering the interior of the rotating shaft 203 and accumulating inside the rotating shaft 203.

[0070] Reference Figure 1As shown, in some embodiments of this utility model, the gas supply device 400 includes a gas supply pipe 410. The gas supply pipe 410 is rotatably connected to the top end of the stirring part 200 via a rotary joint 420, thereby preventing the gas supply pipe 410 from rotating with the stirring part 200. Specifically, the gas supply pipe 410 is rotatably connected to the top end of the rotating shaft 203 via the rotary joint 420; the end of the gas supply pipe 410 away from the rotary joint 420 is connected to a gas source (not shown) to deliver gas into the gas supply pipe 410 and deliver it into the airflow channel 201 via the rotary joint 420.

[0071] Reference Figure 1 and Figure 3 As shown, in some embodiments of this utility model, a first heating part 430 is provided in the gas supply pipe 410. The first heating part 430 is used to heat the gas supplied by the gas source to the air flow channel 201. The advantage of this arrangement is that while performing pneumatic stirring, the first heating part 430 can also be used to heat the gas, thereby heating the lubricating oil in the mixing chamber 101.

[0072] It is conceivable that, in actual use, when the lubricating oil is first mixed, the first heating unit 430 and the first heating unit 430 can be started at the same time to increase the heating speed and save time. When the temperature rises to the set range, the first heating unit 430 can be stopped and only the first heating unit 430 can be used to regulate the temperature to save energy. Of course, the first heating unit 430 can also be stopped.

[0073] Reference Figures 1 to 3 As shown, in some embodiments of this utility model, the gas supply pipe 410 includes a main pipe 411 and a branch pipe 412. The main pipe 411 is arranged vertically, and its bottom end is connected to the stirring part 200 through a rotary joint 420. A pipe cap 440 is detachably connected to its top end. A bracket 441 is provided on the inner side of the pipe cap 440, and a first heating part 430 is installed on the bracket 441, which facilitates the disassembly and maintenance of the first heating part 430. One end of the branch pipe 412 is connected to the periphery of the main pipe 411, and the other end is connected to the gas source. The first heating part 430 is at least partially located on the side near the rotary joint 420 at the connection between the branch pipe 412 and the main pipe 411.

[0074] Based on the above embodiments, in some specific embodiments, refer to Figure 3 As shown, the first heating part 430 is configured as a heating wire, which is wound around the bracket 441. Specifically, the heating wire is wound vertically spirally around the bracket 441. In addition, the connecting wire of the heating wire passes through the tube cover 440, and the passing position is sealed. It is conceivable that the first heating part 430 can also be a heating tube.

[0075] Reference Figure 3As shown, in some embodiments of this utility model, the inner wall of the pipe cover 440 is provided with an internal thread, and the outer wall of the main pipe 411 is provided with an external thread, so as to be threadedly connected with the pipe cover 440, making disassembly and assembly very convenient.
