Description

Technical Field

[0001] This utility model relates to the field of lubricating oil production equipment, and in particular to a temperature-controlled wind power lubricating oil mixing tank. Background Technology

[0002] A wind turbine lubricating oil mixing tank is a piece of equipment used in the lubricating oil production process. It is primarily used for stirring, mixing, blending, and homogenizing lubricating oil. It plays a crucial role in the lubricating oil production process, ensuring the quality and performance of the lubricating oil. Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and machinery to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. In the lubricating oil production process, various raw materials need to be mixed in a specific ratio and thoroughly stirred to ensure the quality and performance of the product.

[0003] In recent years, the technology of wind turbine lubricating oil mixing tanks has developed rapidly, resulting in many new types of mixing tanks, such as lubricating oil mixing tanks with multi-layer heating functions and patented equipment for lubricating oil blending devices. These new mixing tanks not only improve production efficiency but also enhance product quality and performance. For example, a lubricating oil mixing tank with multi-layer heating function can heat different layers at different temperatures according to different heating needs, overcoming the shortcomings of traditional mixing tanks in terms of heating. Another patented device for lubricating oil blending can mix and stir lubricating oil in different directions, reducing stirring time and ensuring blending uniformity. These technological advancements have not only driven the progress of the lubricating oil production industry but also provided support for the development of other related industries.

[0004] However, existing lubricating oil mixing tanks often encounter the following problems during use: Traditional lubricating oil frequently experiences temperature fluctuations during mixing, and temperature plays a crucial role in this process. If the temperature is too high during mixing, the molecular motion within the lubricating oil intensifies, potentially altering intermolecular forces. This can easily lead to emulsification reactions between the lubricating oil and any water or other substances it may contain. Conversely, if the temperature is too low during mixing, the lubricating oil's fluidity decreases, and some components may experience uneven coagulation or agglomeration, further triggering emulsification and affecting the quality of the lubricating oil. Utility Model Content

[0005] The main objective of this invention is to provide a temperature-controlled wind power lubricating oil mixing tank to effectively solve the problem mentioned in the background art where temperature fluctuations often occur during the mixing process of existing traditional lubricating oils, leading to emulsification.

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.

[0044] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] like Figure 1-4 As shown, a temperature-controlled wind-powered lubricating oil mixing tank includes: a tank body 1, an inner layer 101, an outer layer 102, an insulation layer 103, a tank cover 2, an opening and closing plate 3, a vertical drive motor 4, a stirring shaft 5, a first stirring blade 6, a second stirring blade 7, an electric heating plate 8, a condenser pipe 9, and a sealing port 10. The tank body 1 is mounted on the ground, the tank cover 2 is fastened to the top of the tank body 1, the opening and closing plate 3 is located on the tank cover 2, the vertical drive motor 4 accelerates the top of the tank cover 2, and the stirring shaft 5 is located at the output end of the vertical drive motor 4. The stirring shaft 5 is made of solid 316L stainless steel, and its diameter is determined according to the size of the mixing tank and the required stirring power. For example, for a 1000L mixing tank, the diameter of the stirring shaft 5 can be set to 50mm. The sealing between the stirring shaft 5 and the top of the tank body 1 is a mechanical seal to prevent lubricating oil leakage. The mechanical seal has a cooling jacket to prevent overheating damage to the seal. The first agitator 6 is connected to the shaft of the agitator 5; the first agitator 6 is a frame-shaped agitator, and the second agitator 7 is located below the first agitator 6; the second agitator 7 is an inclined blade agitator.

[0046] In this embodiment, as Figure 2-4As shown, the electric heating plate 8 is laid on the bottom surface of the inner wall of the tank 1, and is located at the bottom of the tank 1. The electric heating plate 8 uses stainless steel armored electric heating elements with moderate surface power density to prevent local overheating. The condenser tube 9 is spirally laid on the inner wall of the tank 1; one end of the condenser tube 9 passes through the sealing port 10 and is connected to the outlet of the circulation pump 13 through the sealing joint 11, and the other end of the condenser tube 9 passes through the tank cover 2 and extends to the outside of the tank 1. The sealing port 10 is opened in the tank body of the tank 1, and the sealing joint 11 is threadedly connected to the sealing port 10. One end of the heat insulation tube 12 is connected to the sealing joint 11, and the other end of the heat insulation tube 12 is connected to the circulation pump 13; the circulation pump 13 is located on one side of the tank 1, and the inlet pipe 14 is connected to the inlet of the circulation pump 13.

[0047] To ensure the insulation of tank 1, the structure includes: an inner layer 101 disposed inside tank 1, an outer layer 102 fitted onto the inner layer 101, with a gap between the inner layer 101 and the outer layer 102, and an insulation layer 103 filling the gap between the inner layer 101 and the outer layer 102. A double-layer structure is adopted; the inner layer 101 is made of stainless steel, providing good corrosion resistance, while the outer layer 102 is made of carbon steel, with insulation material such as rock wool filling the gap to reduce heat loss. A manhole is provided at the top of tank 1 for convenient maintenance and inspection of internal components; the manhole is equipped with a sealing cap to prevent dust and moisture from entering.

[0048] Preferably, the mounting base 15 is located on the top of the tank cover 2, and the temperature sensor 16 passes through the mounting base 15, extending into the tank body 1. The temperature controller 17 is electrically connected to the temperature sensor 16. The temperature controller 17 is also electrically connected to the electric heating plate 8. The heating plate is connected to the temperature controller 17, which can set a target temperature. When the temperature of the lubricating oil in the tank is lower than the target temperature, the heating plate automatically operates. The temperature controller 17 is electrically connected to the circulating pump 13, and the sealing ring 18 is fitted onto the sealing joint 11. The flow rate of the cooling medium is controlled by an electromagnetic flow regulating valve, which is connected to the temperature controller 17. When the temperature of the lubricating oil in the tank is higher than the target temperature, the temperature controller 17 sends a signal to open the electromagnetic flow regulating valve, allowing cooling water to pass through the spiral cooling pipe, carrying away heat and lowering the temperature of the lubricating oil.

[0049] It should be noted that the temperature-controlled wind-powered lubricating oil mixing tank designed in this utility model is used by starting the vertical drive motor 4, which drives the stirring shaft 5. The rotation of the stirring shaft 5 causes the first stirring blade 6 and the second stirring blade 7 to rotate. The upper blades are frame-type blades, used to generate a large circulating flow to ensure the overall mixing effect of the lubricating oil in the tank; the lower blades are inclined turbine blades, mainly used to generate strong shear force to break up any local agglomerates that may form. The blades are made of 316L stainless steel with a polished surface to reduce contamination of the lubricating oil. In case of an abnormal temperature, the temperature sensor 16 will provide real-time feedback to the temperature controller 17. The temperature controller 17 will then activate the temperature control device to regulate the temperature. Taking cooling as an example, if the temperature inside the tank 1 is too high, the temperature sensor 16 will send a command to the circulation pump 13. The circulation pump 13 will draw the cooling medium into the delivery pipe 14, and then guide the cooling medium into the condenser pipe 9. The cooling medium flows inside the spirally laid condenser pipe 9 to cool the lubricating oil inside the tank 1. Finally, it will be sprayed out from the other end of the condenser pipe 9, ensuring that the temperature of the lubricating oil inside the tank is controlled within the set range. Generally, the temperature can be controlled between 30-50℃. This temperature range helps to prevent emulsification.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
