Description

Technical Field

[0001] The invention relates to the technical field of insulating oil recovery, in particular to a transformer insulating oil recovery bin and a recovery method thereof. Background Art

[0002] Transformer insulating oil, also known as transformer oil or transformer insulating medium oil, plays a vital role in the operation of the transformer. It has functions such as insulation and heat dissipation. Transformer insulating oil is an oil specially used for insulation and cooling of transformers. It is usually a mineral oil, but it can also be a synthetic oil or bio-oil. According to the source and properties of the oil, transformer insulating oil is mainly divided into two categories: mineral insulating oil and synthetic insulating oil. Mineral insulating oil is extracted from natural petroleum, while synthetic insulating oil is made by chemical synthesis. With the use and maintenance of the transformer, insulating oil that needs to be recycled will be produced.

[0003] The transformer insulating oil recovery bin is a device specifically used to recycle these insulating oils. The transformer insulating oil recovery bin is a closed container or system designed to safely and effectively collect and store insulating oil recovered from transformers. The recovery bin usually has a certain capacity and can safely store the recovered insulating oil waiting for further processing. It is designed to ensure the efficiency and safety of the recycling process, prevent insulating oil leakage from polluting the environment, and provide convenient conditions for subsequent processing and reuse.

The core 607 and the ion exchange resin 608 are both connected to the inner wall of the support frame 601, and the limiting assembly 8 includes a fixing plate 801 fixedly connected to the outer surface of the baffle 602, and the outer surface of the fixing plate 801 is slidably connected with an insertion rod 802, and the end of the insertion rod 802 is plugged into the ear 7, and the end of the insertion rod 802 away from the ear 7 is fixedly connected with a pull block 803, and the outer surface of the insertion rod 802 is sleeved with a spring 804, one end of the spring 804 is fixedly connected to the outer surface of the fixing plate 801, and one end of the spring 804 is fixedly connected to the outer surface of the pull block 803.

[0028] In this embodiment, the inner wall of the carrier 601 is provided with four mounting grooves for placing filter materials of different levels. The outer surface of the pull ring 603 can be covered with a non-slip rubber pad. When the operator holds the pull ring 603 and pulls it, the outer surface of the operator's palm can be protected to avoid scratching the skin. The filter paper 605 has good filtering performance and can remove larger particle impurities in the insulating oil. It is relatively cheap and widely used. The filter cloth 606 can be made of cotton and has good adsorption performance. It can adsorb some tiny particles and impurities in the insulating oil. The texture is soft and it is not easy to damage the molecular structure of the insulating oil. The filter element 607 is made of activated carbon. The filter element 607 can remove the odor, color and some organic impurities in the insulating oil. The insulating oil will contact with the ion exchange resin 608.

[0029] The working steps of this embodiment are as follows: like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, after the insulating oil enters the filter chamber 101, it will first contact with the filter paper 605 for primary filtration. The filter paper 605 can remove larger particles of impurities in the insulating oil. Secondly, the insulating oil after preliminary filtration will contact with the filter cloth 606. At this time, the filter cloth 606 can absorb some tiny particles and impurities in the insulating oil, thereby achieving a secondary filtration effect on the insulating oil. The insulating oil will contact with the filter element 607. At this time, the filter element 607 can remove the odor, color and some organic impurities in the insulating oil, thereby achieving a third filtration of the insulating oil. Finally, the insulating oil will contact with the ion exchange resin 608. At this time, the ion exchange resin 608 can replace harmful ions in the insulating oil with harmless ions, thereby improving the purity and performance of the insulating oil. At this time, the fourth filtration of the insulating oil is achieved. Through multi-stage filtration of the insulating oil, an effective filtering and recovery effect of the insulating oil is achieved. When the filter assembly 6 needs to be disassembled and cleaned, first pull the pull block 803 to move close to the pull ring 603. At this time, the plug rod 802 will be pulled out of the ear 7, thereby releasing the fixed limiting effect on the baffle 602, and the filter assembly 6 can be easily taken out from the inside of the filter bin 101. Pulling the pull block 803 will stretch the elastic member 804, thereby causing the elastic member 804 to deform and store a certain amount of elastic potential energy. When the pull block 803 is released, the elastic member 804 will release the elastic potential energy, thereby driving the pull block 803 and the plug rod 802 to move in the direction, so that the plug rod 802 is reinserted into the ear 7, and the baffle 602 is fixed again, which is convenient for the installation of the cleaned filter assembly 6.

Under the action of gas pressure, it can move upward through the piston plate 112. When the piston plate 112 moves above the exhaust hole 113, the gas can be discharged through the exhaust hole 113, and the recovery bin body 1 can be exhausted to avoid excessive gas pressure inside the recovery bin body 1. Rotating the rotating block 117 can drive the screw rod 116 to rotate. By utilizing the threaded cooperation between the screw rod 116 and the exhaust pipe 111, the rotation of the screw rod 116 can drive the connecting plate 114 to move under the guidance of the guide cylinder 118 and the guide rod 119, thereby changing the distance between the connecting plate 114 and the piston plate 112, and changing the elastic force provided by the spring 115 when the piston plate 112 moves above the exhaust hole 113, so as to facilitate the adjustment of the pressure relief pressure critical value of the device and facilitate the use of the recovery bin.

10. A method for recycling transformer insulating oil recovery bin, characterized in that: The method comprises the following steps: The oil pump 1 (2) works to extract the insulating oil in the insulating oil tank through the oil pipe 1 (3), and the oil pipe 2 (4) transports the extracted insulating oil into the interior of the filter bin (101); After the insulating oil enters the filter chamber (101), it first contacts the filter paper (605) for primary filtration, and the filter paper (605) can remove larger particle impurities in the insulating oil. After the initial filtration, the insulating oil will come into contact with the filter cloth (606), and at this time, the filter cloth (606) can absorb some tiny particles and impurities in the insulating oil, thereby achieving secondary filtration of the insulating oil; Then the insulating oil contacts the filter element (607), and the filter element (607) can remove the odor, color and some organic impurities in the insulating oil, thereby achieving a third filtration of the insulating oil; Finally, the insulating oil will come into contact with the ion exchange resin (608), at which point the ion exchange resin (608) can replace harmful ions in the insulating oil with harmless ions, thereby improving the purity and performance of the insulating oil. At this point, the fourth filtration of the insulating oil is achieved; The transformer insulating oil after filtering is accumulated at the bottom of the filtering bin (101). The oil pump 2 (9) can inject the filtered insulating oil into the interior of the recovery bin (1) through the oil pipe 3 (10) for recovery and storage, so as to facilitate subsequent treatment and processing.
