Five, the specific embodiment

As shown in Figure 1 to Figure 3, the utility model tramp iron separator is made of conservator 11, inside and outside circulating cooling system and oil injection type magnetic system.Pouring orifice and line outlet and oil duct 12 are arranged on the conservator 11, cooling medium 13 is provided for oil injection type magnetic system by 2 oil ducts 12.Cooling medium 13 is selected insulating properties and the good transformer oil of mobile performance for use.Oil level alarm 16 also is installed on the conservator 11.The lead that is connected with the magnet exciting coil 2 of oil injection type magnetic system is drawn with terminal box 10 from line outlet through the oil duct 12 of a side and is connected, and terminal box 10 is fixed on oil injection type magnetic and fastens face.The warm alarm 19 of oil is installed on the oil injection type magnetic system.Oil injection type magnetic system adopts is will be fixed on the iron core 2 on the yoke plate 1 and be wrapped in magnet exciting coil 3 on the iron core 2 is enclosed in by the totally enclosed frame that yoke plate 1, magnetic conductive cylinder 4, supporting plate 5 assembly weldings form.17 is the hanger of the utility model tramp iron separator, is welded on the yoke plate 1.18 for being installed in the fuel outlet valve that oil injection type magnetic is the bottom.Magnet exciting coil 3 per 4 layers be one group, separate passage 15 with insulating bar 14 between each group as cooling medium 13, to increase the effective heat exchange area of magnet exciting coil 3, improve radiating efficiency, slow down the aging speed of magnet exciting coil with being effective, and reduced the total height of magnetic system, the magnetic circuit of its oil injection type magnetic system is shortened, and leakage field reduces, and magnetic loss is little, magnetic field gradient is big, deironing rate height.According to different needs, magnetic field intensity can be selected in the 700-1500GS scope, and as special operation condition, magnetic field intensity also can strengthen.In order to solve temperature rise and the deep fat expansion issues that produces when large-scale oil injection type tramp iron separator is worked better, the utility model tramp iron separator has adopted the inside and outside circulating cooling system of being made up of kinetic pump 7, inside and outside circulating oil path and radiator 8, its kinetic pump 7, outer circulation oil circuit and radiator 8 are fixed on oil injection type magnetic and fasten face, make structure of the present utility model compact more.Described inside and outside circulating oil path is to be made of interior oil circuit and outer circulation oil circuit.Interior oil circuit refers to the passage of respectively organizing cooling medium between magnet exciting coil 15 of oil injection type magnetic system, current divider 9A, 9B that the outer circulation oil circuit adopts can select identical tubular construction for use, the sealing of one end, the other end is provided with connector and is connected with radiator, and the interface that links to each other with oil pipe 6A or 6B is arranged on its barrel.With oil injection type magnetic is that 4 oil pipe 6A that inner chamber communicates import the current divider 9A that is connected with radiator 8 cooling medium inlets; The cooling-oil outlet of radiator 8 is communicated with current divider 9B, and current divider 9B is connected with the oil pipe 6B that 4 connection oil injection type magnetic are inner chamber.Kinetic pump 7 can be connected on the pipeline of cooling medium inlet of radiator 8, also can be connected on the pipeline of cooling medium outlet of radiator 8;
