Detailed ways

The specific embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the utility model, and are not intended to limit the utility model.

The utility model provides a waste oil recycling device for an electric dust removal transformer, which is used for recycling the waste oil produced by the electric dust removal transformer. As shown in FIG. 1 , the waste oil recovery device includes an oil collecting pan 1 for placing under the transformer 100 and an oil storage tank 2 arranged at a position below the oil collecting pan 1 , and the oil collecting pan 1 passes through the oil guide pipe 3 Connect with oil storage tank 2.

By placing the oil collecting pan 1 under the transformer 100, the waste oil generated by the transformer 100 under various working conditions will flow directly into the oil collecting pan 1. Preferably, the oil collecting pan 1 is large at the top and small at the bottom. Conical structure, the oil guide pipe 3 is connected to the middle of the bottom of the conical structure of the oil collection pan 1, and the waste oil collected in the oil collection pan 1 flows into the oil storage tank 2 through the oil guide pipe 3, so as to realize the collection of transformer waste oil and achieve environmental protection Production requirements, and the collected waste oil can be reused to save resources.

Further, in order to enable the collected waste oil to be recycled and reused, a filter screen 4 is arranged between the oil storage tank 2 and the oil collection pan 1 for filtering the oil entering the oil storage tank 2 from the oil collection pan 1 , to filter out impurities such as particles in waste oil.

After the filter screen 4 has been used for a period of time, the impurities in the waste oil will easily block the filter screen. Therefore, the filter screen 4 needs to be cleaned regularly. For the convenience of cleaning, as shown in Figure 1, the filter screen 4 is set to At the connection between the oil storage tank 2 and the oil guide pipe 3, and at the position close to the filter screen 4, a hand hole door 6 is arranged on the tank wall of the oil storage tank 2. Open the hand hole door 6, and the filter screen 4 can be taken out to clean the filter screen. 4. Clean up. After cleaning, the filter screen 4 is put back into the original place by the hand hole door 6.

The setting of the filter screen 4 is not limited to the position shown in Figure 1. In this embodiment, the filter screen 4 is arranged at the junction of the oil storage tank 2 and the oil guide pipe 3, which is a preferred method for cleaning the filter screen 4 for convenience. implementation. Also can be arranged on the bottom of oil collecting pan 1 as filter screen 4, the waste oil in oil collecting pan 1 enters in the oil guide pipe 3 again after passing through filter screen 4.

During actual use, if the filter screen 4 is not cleaned in time, causing the filter screen 4 to be blocked, the oil cannot flow into the oil storage tank 2 through the filter screen 4 or the flow is too slow. In order to prevent the oil collected in the oil collecting pan 1 from If it overflows beyond a certain amount, the oil guide pipe 3 branches out to the overflow pipe 5 communicating with the oil storage tank 2, and the overflow pipe is arranged between the oil collecting pan 1 and the filter screen 4, so that the oil collected by the oil collecting pan 1 When it cannot enter into the oil storage tank 1 through the filter screen 4, it can enter into the oil storage tank 2 through the overflow pipe 5, and the oil liquid will not overflow.
