Embodiment Construction
[0014] Below, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments,
[0015] to combine Figure 1-Figure 3 , the degreasing equipment for cleaning the oil on the inner surface of copper pipes of the present invention includes a heating device 1 for heating the cleaned copper pipes 2; an air blowing device for blowing nitrogen into the heated copper pipes 3 to blow The gas device includes a high-pressure nitrogen tank 3 as a high-pressure gas source and a gas supply interface 4 connected to the copper pipe 2. There are 5 air supply pipelines 5 (6, 7, 8, 9) between them, and each air supply pipeline is connected in series with a pressure reducing valve 51 (61, 71, 81, 91) and a valve for closing or conducting the pipeline. The electronic valve 52 (62, 72, 82, 92), the outlet pressure value of the pressure reducing valve of each gas supply pipeline is different, when blowing air to the copper pipe, only one gas su...

The invention discloses oil removal equipment for removing oil containment on the inner surface of a copper pipe. The oil removal equipment comprise a heating device and a gas blowing device, whereinthe heating device is used for heating the cleaned copper pipe, and the gas blowing device is used for blowing gas into the heated copper pipe. The oil removal equipment is characterized in that the gas blowing device for removing oil containment on the inner surface of the copper pipe comprises a high-pressure gas source and a gas supply port in butted connection with the copper pipe, a pluralityof gas supply pipelines are arranged between the high pressure gas source and the gas supply port, each gas supply pipeline is sequentially connected with a pressure reducing valve and a valve body for closing or opening the pipeline in series, outlet pressure values of the pressure reducing valves of the gas supply pipelines are different, and during air blowing, only one gas supply pipeline isin an opened state. The oil removal equipment has the advantages that when the air blowing device cleans the copper pipe, gas can be supplied to the copper pipe in the mode of selecting different pressure according to the length of the copper pipe, and cleanliness and cleaning efficiency are improved.
Description
technical field [0001] The invention relates to a degreasing device for cleaning the oil stain on the inner surface of a copper pipe. Background technique [0002] The production method of the final annealing process of the copper tube large coil is that the copper tube will be laid out in the pay-off area, and the copper tube will be heated to about 600 degrees quickly through the heating zone through induction heating, and cooled to below 50 degrees after passing through the cooling zone, and then in the receiving area. The wire area harvests copper tubes into coils. There are two main processing purposes in this process, one is to anneal and soften the copper tube; the other is to remove the residual oil on the inner surface of the copper tube. When the copper tube quickly passes through the induction heating zone, the temperature rises sharply, and the residual oil on the surface of the tube will also volatilize into a gaseous state due to high temperature. At this time...
