[0007] Furthermore, the spray pipe is connected to a liquid inlet pipe, one end of which extends into the bottom of the filter box. A pump is installed on the liquid inlet pipe, and the emulsion in the filter box is pumped into the liquid inlet pipe by the pump and sprayed out from the spray pipe.

[0008] Compared with the prior art, the utility model has the following advantages: 1. By setting an overflow box and multiple overflow ports, the fluidity of the floating oil in the emulsion of the magnetic filter box is accelerated, and the oil quickly overflows into the clean liquid tank for stirring and fusion, which can effectively reduce the accumulation of the emulsion by more than 60%; 2. By setting a spray pipe, the emulsion is sprayed toward the overflow port to enhance the fluidity of the emulsion surface in the filter box, so that the floating oil quickly overflows into the overflow box, which can effectively reduce the accumulation of the floating oil in the emulsion of the filter box by about 30%; 3. The magnetic rod is flushed through the spray pipe to reduce the amount of floating oil adsorbed by the magnetic rod on the iron powder, thereby reducing the loss of rolling oil.

[0014] See also Figure 1-4 The present embodiment is an emulsion magnetic filtration device for reducing floating oil loss, comprising a filter box 1, wherein two circulation chains 2 are arranged in the filter box 1, and the two circulation chains 2 are connected to the same set of driving mechanisms, and a plurality of magnetic rods 9 are evenly distributed between the two circulation chains 2, and the magnetic rods 9 circulate along with the circulation chains 2. An overflow box 8 is provided on one side of the filter box 1, and the overflow box 8 is connected to the bottom of the filter box 1. A plurality of overflow ports 3 are provided on the upper ends of the filter box 1 and the overflow box 8, and the plurality of overflow ports 3 are arranged in a horizontal row, and a spray pipe 4 is provided on the other side of the upper end of the filter box 1 relative to the overflow port 3, and the spray pipe 4 is arranged in a horizontal direction and perpendicular to the magnetic rod 9, and the spray pipe 4 is located above the overflow port 3, and a plurality of spray holes are provided on the spray pipe 4 along the length direction, and the spray holes are arranged toward the overflow port 3.

[0015] Furthermore, a suspension rod 5 is respectively provided at both ends of the spray pipe 4 , and the top end of the suspension rod 5 is fixedly connected to the filter box 1 , and the spray pipe 4 is suspended in the filter box 1 through the suspension rod 5 .

[0016] Furthermore, the suspension rod 5 is a screw rod, which passes through the cover plate of the filter box 1. An adjusting nut is installed on the upper and lower sides of the suspension rod 5 of the filter box 1. The length of the suspension rod 5 extending into the filter box 1 is adjusted by adjusting the adjusting nut, thereby adjusting the height of the spray pipe 4.

[0017] Furthermore, the spray pipe 4 is connected to a liquid inlet pipe 6, one end of which extends into the bottom of the filter box 1. A pump is installed on the liquid inlet pipe 6, and the emulsion in the filter box 1 is pumped into the liquid inlet pipe 6 by the pump and sprayed out from the spray pipe 4. A regulating valve 7 is installed on the liquid inlet pipe 6, and the regulating valve 7 is used to adjust the flow meter flow rate of the emulsion sprayed out of the spray pipe 4.

[0018] The working principle of the utility model is as follows: by setting the overflow port 3, the floating oil on the surface of the emulsion in the filter box 1 overflows into the overflow box 8, and a stirring device is set in the overflow box 8 to make the floating oil merge with the emulsion again. The emulsion at the bottom of the overflow box 8 flows into the filter box 1 through the bottom connecting port, which reduces the loss of floating oil on the one hand and keeps the concentration of the emulsion stable on the other hand; a row of multiple spray holes arranged on the spray pipe 4 spray the emulsion toward the magnetic rod 9, and the flow rate of the sprayed emulsion is adjusted to a suitable value by the regulating valve 7, so as to achieve the effect of micro-flushing the magnetic rod 9, so that the iron filings adsorbed on the magnetic rod 9 will not be washed away, and the floating oil adhering to the iron filings will be washed off, so as to further reduce the loss of floating oil.
