[0001] The utility model relates to the technical field of oil filtering, and particularly relates to an oil filtering device for motor disassembly. Background Technique

[0002] Both the stator and rotor in an oil-immersed motor are immersed in insulating oil, and the insulating oil plays multiple roles such as insulation, heat dissipation, and lubrication. For example, in some cooling motors supporting large power transformers, the oil-immersed design can effectively transfer the heat generated during motor operation. Because the specific heat capacity of oil is relatively large, it can absorb and carry away a large amount of heat, thus ensuring that the motor operates within a suitable temperature range.

[0003] When a motor fails and needs to be disassembled, and there is a certain amount of oil inside the motor, to avoid the random flow of oil, basins or containers are used to collect the oil. However, these oil storage devices do not have the effect of filtering the oil, resulting in the collection of sludge impurities in the oil, which affects the oil recovery effect. Therefore, an oil filtering device for motor disassembly is proposed to solve the above problems. Content of the Utility Model

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example

[0029] Reference Figures 1-4 This utility model provides a technical solution: an oil filtration device for motor disassembly, including a housing 1 and an oil filtration mechanism 3, with a placement plate 2 installed at the upper end of the housing 1. The oil filtration mechanism 3 includes a filter plate 31, which is installed inside the housing 1 and positioned below the placement plate 2. A receiving plate 32 is positioned below the filter plate 31, and a control motor 321 is installed at the bottom of the receiving plate 32. A centrifuge cylinder 322 is installed at the output end of the control motor 321, and an oil-liquid separation membrane 33 is positioned below the receiving plate 32.

[0030] This device places the filter plate 31 at the top to filter large impurities such as sludge in the oil. After the oil enters the centrifuge cylinder 322, it can be further filtered under centrifugal force. Finally, it passes through the oil separation membrane 33 for filtration, thereby improving the filtration effect of the oil and the oil recovery effect to meet the requirements of use.

[0031] In a preferred embodiment, the upper surface of the placement plate 2 is provided with a through hole 4, which extends through the interior of the placement plate 2. A placement chamber 5 is also fixedly installed on the upper surface of the placement plate 2 for placing parts. The placement chamber 5 is provided on the placement plate 2, and the bottom of the placement chamber 5 is provided with an opening, so that the interior of the through hole 4 covered by the placement chamber 5 is connected to the interior of the placement chamber 5. In actual operation, the operator can use a wrench to unscrew the screws on the motor and place the screws inside the placement chamber 5. When some parts inside the motor are also placed inside the placement chamber 5, the parts are covered with oil. The oil can drip through the through hole 4 onto the filter plate 31, thereby filtering the oil and preventing the oil from polluting the surrounding environment, which is convenient for use.

[0032] In a preferred embodiment, a pad 6 is fixedly installed on the inner wall of the outer casing 1, and a filter plate 31 is provided on the pad 6. The filter plate 31 is installed on the pad 6 by bolts. After long-term use, the filtering effect of the filter plate 31 on oil will gradually deteriorate. At this time, the filter plate 31 needs to be removed for cleaning. The placement plate 2 can be removed from the inside of the outer casing 1, exposing the bolts. The bolts can be unscrewed with tools, and the filter plate 31 can be removed from the inside of the outer casing 1 for cleaning.

[0033] In a preferred embodiment, a rectangular plate 7 is fixedly installed inside the outer casing 1. A circular hole 8 is provided on the upper surface of the rectangular plate 7, and an oil separation membrane 33 is installed on the rectangular plate 7. The device has a rectangular plate 7 hidden below the oil separation membrane 33, which can stably install the oil separation membrane 33 and make it stable for use. The oil separation membrane 33 is spread out on the rectangular plate 7, which can ensure that the oil flowing out of the centrifuge 322 falls onto the oil separation membrane 33, which can further filter the oil and improve the filtration effect. Furthermore, the circular hole 8 is provided on the rectangular plate 7. After the oil passes through the inside of the oil separation membrane 33, it can continue to fall through the circular hole 8 until it falls onto the inclined plate 101, which can facilitate the discharge of the oil.

[0034] When the oil is ejected from the inside of the centrifuge drum 322 and passes through the inside of the receiving plate 32, it will fall onto the oil separation membrane 33. To prevent the oil from falling onto the control motor 321, a partition 13 is fixedly installed at the bottom of the receiving plate 32 and positioned on the left and right sides of the control motor 321. When the oil falls, it will be blocked by the partition 13 and will not fall from the position of the control motor 321, thus preventing the oil from splashing onto the control motor 321 and ensuring that the control motor 321 can be used normally.

[0035] This device uses a centrifuge cylinder 322 to further filter the oil. To ensure that all the oil on the filter plate 31 enters the centrifuge cylinder 322, a conical cylinder 9 is fixedly installed at the bottom of the filter plate 31. The bottom of the conical cylinder 9 is located inside the centrifuge cylinder 322. After passing through the interior of the filter plate 31, the oil will continue to fall and enter the interior of the conical cylinder 9. After passing through the interior of the conical cylinder 9, the oil will fall directly into the centrifuge cylinder 322. When the device is in use, the control motor 321 is turned on, so that the control motor 321 controls the centrifuge cylinder 322 to rotate continuously. After the oil enters the interior of the centrifuge cylinder 322, it can directly undergo centrifugal motion, that is, further filter the oil to meet the requirements.

[0036] After the oil passes through the oil separation membrane 33, the oil filtration effect is completed, and then the oil is discharged. An oil outlet mechanism 10 is provided inside the outer shell 1. The oil outlet mechanism 10 includes an inclined plate 101, which is fixedly installed at the bottom of the inner shell 1. A limiting plate 102 is fixedly installed on the upper surface of the inclined plate 101. An oil outlet pipe 11 is fixedly installed on the outer surface of the outer shell 1. A control valve 12 is installed on the oil outlet pipe 11. One end of the oil outlet pipe 11 corresponds to the bottom end of the inclined plate 101, and the interior of the oil outlet pipe 11 is connected to the interior of the outer shell 1.

[0037] In actual use, the oil flows through the inside of the oil separation membrane 33 and falls onto the inclined plate 101. Because the inclined plate 101 has a certain inclination, the oil will flow on the inclined plate 101, from high to low position, and towards the oil outlet pipe 11. Under the limitation of the limiting plate 102, the oil will slide to the position of the oil outlet pipe 11. Since the outer surface of the limiting plate 102 is set as a slope, the oil falling on the limiting plate 102 can also flow towards the position of the oil outlet pipe 11, and finally the oil flows out from the position of the oil outlet pipe 11.

[0038] Specifically, the working process or working principle of an oil filter device for motor dismantling is as follows: When a motor malfunctions, it needs to be dismantled. There is a certain amount of oil inside the motor. To prevent the oil from flowing freely, a basin or container is used to collect the oil. However, these oil collection devices do not have the effect of filtering the oil, which causes oil sludge and impurities in the oil to be collected as well, affecting the oil recovery effect. Therefore, this device was designed to solve this problem.

[0039] This device can filter the oil inside the motor, removing impurities and improving oil recovery efficiency. It is easy to use. Specifically, the motor that needs repair can be placed on the placement plate 2. The motor can be disassembled using external tools. The disassembled screws and other parts can be placed inside the placement compartment 5 to prevent loss. Since there is oil inside the motor, when the motor housing 1 is removed, oil will flow out. This oil will fall through the through hole 4 to the position of the filter plate 31. The oil is filtered by the filter plate 31, and some impurities are filtered onto the filter plate 31.

[0040] After the oil passes through the filter plate 31, it enters the conical cylinder 9. Inside the conical cylinder 9, the oil falls into the centrifuge cylinder 322. Driven by the control motor 321, the centrifuge cylinder 322 rotates rapidly, causing the oil inside to undergo centrifugal motion, thus filtering the oil. The oil is thrown out, while impurities remain inside the centrifuge cylinder 322. The thrown-out oil falls onto the oil separation membrane 33 via the receiving plate 32, where it is continuously filtered, thereby improving the filtration effect.

[0041] The oil flows through the inside of the oil separation membrane 33 and falls onto the inclined plate 101. Because the inclined plate 101 has a certain inclination, the oil flows on the inclined plate 101 and towards the oil outlet pipe 11, eventually causing the oil to flow out from the oil outlet pipe 11 and be collected, thus improving the oil recovery effect.
