Description

Technical Field

[0001] This utility model relates to the field of waste oil treatment technology, specifically a waste oil treatment device for wind turbine generators. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. When maintaining a wind turbine, some waste oil is generated. The waste oil can be collected, treated, and reused by using a waste oil treatment device.

[0003] In winter, the temperature at wind farms in northern regions is generally below -20℃. This causes the waste oil-water mixture inside the waste oil drums to freeze. This makes it difficult for on-site personnel to remove the mixture in a timely manner. In addition, the volume of the frozen waste oil-water mixture decreases. When the temperature warms up in spring, the mixture melts and expands, causing the waste liquid to overflow from the waste oil drums, contaminating the engine room platform, and posing a risk of slipping and falling injuries to on-site personnel.

[0004] Chinese patent discloses a waste oil collection tank for a wind turbine and a wind turbine generator set (authorization announcement number CN220975331U). The patented technology includes: an oil drain pipe for discharging waste oil from the collection tank body; an oil control valve for controlling the opening and closing of the oil drain pipe and the degree of opening; and a heating sleeve for heating the collection tank body when the waste oil inside freezes, thereby heating the waste oil inside the collection tank body to prevent freezing and timely discharge of waste oil, thus preventing waste oil from overflowing from the collection tank body and causing pollution to the nacelle platform, and improving safety performance.

[0005] However, it has certain drawbacks: it uses a simple collection tank and a heating method to prevent waste oil from solidifying, that is, it heats the waste oil in the collection tank by heating the outer tank to prevent freezing; however, this method relies solely on heat conduction for melting, which is slow, especially for waste oil that has solidified or has high viscosity, it is difficult to quickly restore its fluidity, resulting in poor discharge. Utility Model Content

[0006] The purpose of this invention is to provide a waste oil treatment device for wind turbines to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0009] The processing tank is equipped with a scraping mechanism on its exterior and upper end. The scraping mechanism includes a support ring and an internal toothed ring located on the upper side of the support ring.

[0015] As a further embodiment of this utility model: the heating tube is wound around the outside of the processing tank, and the heat insulation cover is fixedly sleeved on the outside of the processing tank.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention heats the waste oil inside the treatment tank by setting a heating mechanism on the outside of the tank to prevent it from solidifying. It also employs a scraping mechanism driven by a single motor. This motor, through a planetary gear and synchronous belt transmission system, greatly improves the stirring efficiency and thermal uniformity through the stirring rod, thereby accelerating the melting of lumpy waste oil. At the same time, the revolution motion also drives the scraper to continuously adhere to the inner wall of the treatment tank for scraping and cleaning, effectively preventing waste oil from adhering. Ultimately, it achieves the two major functions of efficient stirring and thorough wall scraping through a single power source, ensuring that the waste oil can be completely and smoothly discharged.

[0025] Please see Figures 1-3 In this embodiment of the utility model, a wind turbine waste oil treatment device includes a treatment tank 1 and a discharge pipe 2 fixed to the lower end of the treatment tank 1.

[0026] Processing tank 1 is used for collecting and processing waste oil from wind turbine generators;

[0027] The discharge pipe 2 is used to collect the discharge of waste oil; a valve can be installed between the discharge pipe 2 and the treatment tank 1, preferably a ball valve or a butterfly valve;

[0028] A filter screen can be installed inside the treatment tank 1 to perform preliminary filtration of the incoming waste oil, intercepting larger metal fragments, dust, and other solid impurities. The filter screen is preferably a detachable structure, for example, installed through a slot or bracket inside the tank, making it convenient for maintenance personnel to remove, clean, or replace it regularly. The pore size of the filter screen can be selected according to the target filtration accuracy, for example, between 20 and 60 mesh. Furthermore, the filter screen can be designed to be placed at an angle or have a cup-shaped structure to increase the effective filtration area and guide impurities to settle, avoiding rapid clogging.

[0029] A heating mechanism 3 is provided on the outside of the processing tank 1. The heating mechanism 3 includes a heating pipe 4 and a heat insulation cover 5 located outside the heating pipe 4. The heating pipe 4 is wrapped around the outside of the processing tank 1, and the heat insulation cover 5 is fixedly sleeved on the outside of the processing tank 1.

[0030] The heating tube 4 is preferably an industrial-type flexible electric heating tape or a metal-clad electric heating tube, which is used to heat the inside of the treatment tank 1 to prevent the waste oil from clumping or freezing due to low temperature, making it difficult to discharge.

[0031] The heat insulation cover 5 can adopt a double-layer metal plate structure, with high-temperature heat insulation cotton filling the interlayer.

[0032] exist Figure 1 , Figures 3-5 In the middle: A scraping mechanism 6 is provided on the outside and the top of the processing tank 1. The scraping mechanism 6 includes a support ring 7 and an internal toothed ring 8 located on the upper side of the support ring 7. The support ring 7 is fixedly sleeved on the outside of the processing tank 1 and is located on the upper side of the heating mechanism 3. The internal toothed ring 8 is fixedly connected to the upper end of the processing tank 1. A T-shaped groove 9 distributed in a circumferential direction is opened on the outer surface of the support ring 7. A sliding plate 10 is slidably connected to the inner side of the T-shaped groove 9.

[0033] The slide plate 10 is slidably connected to the T-groove 9 through a T-shaped protrusion at one end, ensuring that the slide plate 10 and all its components can move smoothly along the circumference of the processing tank 1.

[0034] An L-shaped plate 11 is fixedly attached to the upper surface of the slide plate 10. A motor 12 is fixedly attached to the right end of the upper surface of the L-shaped plate 11. A support rod 13 is fixedly attached to the output end of the motor 12. A gear 14 is fixedly attached to the lower end of the support rod 13. The gear 14 meshes with the internal gear ring 8. A rotating rod 15 is rotatably connected through the left end of the upper surface of the L-shaped plate 11.

[0035] Gear 14 and internal gear ring 8 are exposed to the outside, but are designed to be easy to clean manually. The meshing part of gear 14 and internal gear ring 8 can be cleaned of impurities and waste oil regularly to ensure smooth transmission and prevent contamination from affecting normal operation.

[0036] The gear 14 and the internal gear ring 8 are made of high-strength, wear-resistant materials with certain self-lubricating properties, preferably powder metallurgy or metal with surface coating treatment;

[0037] The rotating rod 15 and the L-shaped plate 11 are rotatably connected by a bearing;

[0038] A stirring rod 16 is fixedly connected to the lower end of the rotating rod 15. Synchronous pulleys 17 are fixedly sleeved on the outside of the support rod 13 and the outside of the rotating rod 15. A synchronous belt 18 is movably sleeved on the outside of the two synchronous pulleys 17. The stirring rod 16 is located inside the processing tank 1.

[0039] When the motor 12 starts, its output drives the support rod 13 and gear 14 to rotate. Since the gear 14 meshes with the fixed internal gear ring 8, according to the principle of planetary gears, this meshing will generate a reaction force, forcing the entire L-shaped plate 11 and all its components to begin to "revolve" around the circumference of the internal gear ring 8. When the support rod 13 rotates with the motor output shaft, the power is precisely transmitted to the rotating rod 15 through the synchronous pulley 17 and the synchronous belt 18, driving the rotating rod 15 and the stirring rod 16 at its lower end to "rotate" at high speed. Ultimately, the stirring rod 16 can greatly improve the stirring efficiency, form an effective vortex, break the temperature stratification, make the waste oil in the tank heat evenly, and accelerate the melting of the blocky waste oil.

[0040] exist Figure 3 , Figure 4 and Figure 6 In the middle: A scraper 19 is provided on the lower surface of the L-shaped plate 11 between the support rod 13 and the rotating rod 15. The scraper 19 includes a fixing block 20. A fixing rod 21 is fixedly connected to the lower end of the fixing block 20. A scraper 22 is fixedly connected to the lower end of the fixing rod 21. The scraper 22 is attached to the inner surface of the processing tank 1.

[0041] The scraper 22 is preferably made of polyurethane or fluororubber;

[0042] A limiting rod 23 is fixedly connected to the left side surface of the fixed block 20, and multiple limiting rods 24 are fixedly connected to the left side surface of the fixed block 20 outside the limiting rod 23. A limiting block 25 is movably sleeved on the outside of the limiting rod 23. The limiting block 25 is fixedly connected to the lower surface of the L-shaped plate 11. The limiting rods 24 movably pass through the limiting block 25. A spring 26 is movably sleeved on the outside of the limiting rod 23 between the fixed block 20 and the limiting block 25. One end of the spring 26 is fixedly connected to the fixed block 20, and the other end of the spring 26 is fixedly connected to the limiting block 25.

[0043] When the L-shaped plate 11 rotates around the inner toothed ring 8, it can drive the scraper 22 to clean the inner wall of the treatment tank 1, so as to prevent waste oil from adhering and being difficult to completely discharge.

[0044] The spring 26 is fixed to the fixed block 20 and the spring 26 is fixed to the limit block 25 by screw plugs. The fixed block 20 is fixed to the fixed rod 21 by bolts. After unscrewing the screw plugs and bolts, the limit rod 23 can be pulled to the right, which makes it easy to replace and maintain the spring 26.

[0045] Spring 26 is made of stainless steel, such as 304 stainless steel, for its corrosion resistance and high temperature resistance, making it suitable for waste oil treatment environments;

[0046] The preload of the spring 26 continuously pushes the entire scraper 22 against the inner wall of the treatment tank 1, keeping the scraper 22 in contact with the wall at all times.

[0047] The working principle of this utility model is as follows: When the waste oil generated by the wind turbine is collected into the treatment tank 1, it is first initially filtered by the internal filter screen to intercept solid impurities. When discharge is required, the heating tube 4 in the heating mechanism 3 is turned on to heat the waste oil in the tank to prevent it from being unable to be discharged due to low-temperature solidification or excessive viscosity. After heating for a period of time, the motor 12 is started. The motor 12 drives the gear 14 to rotate along the axis of the treatment tank 1 under the meshing action with the internal gear ring 8. At the same time, the support rod 13 rotates along the axis of the treatment tank 1 through the synchronous wheel 1. 7 and the synchronous belt 18 transmit power to the rotating rod 15, causing the stirring rod 16 to rotate at high speed, forming a compound motion to significantly improve stirring efficiency and heating uniformity, and accelerate the melting of blocky waste oil. During this process, the scraper 19 fixed to the lower surface of the L-shaped plate 11 moves with the revolution, and the scraper 22 at its end always adheres to the inner surface of the treatment tank 1 under the continuous pre-tightening force of the spring 26, thereby scraping off the oil stains attached to the inner wall. Finally, the waste oil that has been heated, stirred and scraped and has recovered good fluidity can be completely discharged by opening the valve on the discharge pipe 2.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
