The shunt pipe 13 is provided with a slurry inlet pipe 14. The slurry inlet pipe 14 is used to be connected with an external liquid supply system. The mineral slurry containing iron ore concentrate is supplied into the slurry inlet pipe 14 through the external liquid supply system. The slurry is then distributed to the three disc filters 11 through the cooperation of the slurry inlet pipe 14 and the shunt pipe 13.

The water outlet ends of the three disc filters 11 are connected with the water outlet pipe 15 through the connecting pipe 12 respectively. The water outlet pipe 15 is used to discharge the water removed by the three disc filters 11 to the outside.

[0021] like Figure 1 As shown in the figure, auxiliary adsorption mechanisms 2 are respectively installed on the left and right sides of the slurry inlet pipe 14. By setting the auxiliary adsorption mechanism 2, the mineral material to be filtered can be pre-treated in cooperation with the filtering mechanism 1, thereby reducing the filtering pressure of the filtering mechanism 1 and improving the filtering effect of the filtering mechanism 1.

[0022] like Figure 2 and Figure 3 As shown in the figure, the auxiliary adsorption mechanism 2 includes a feed pipe 21, the input end of the feed pipe 21 is connected to the slurry feed pipe 14, the output end of the feed pipe 21 is fixedly connected to the input end of the vacuum pump 22, the output end of the vacuum pump 22 is connected to the input end of the auxiliary filtering component 3, the output end of the auxiliary filtering component 3 is fixedly connected to one end of the discharge pipe 23, the other end of the discharge pipe 23 is connected to the diversion pipe 13, the vacuum pump 22 is electrically connected to an external power supply, and the slurry can be sucked from the slurry feed pipe 14 into the auxiliary filtering component 3 for pre-filtration treatment through the vacuum pump 22.

The vacuum pump 22 will suck part of the material through the slurry inlet pipe 14 into the filter box 31, and the material in the ore slurry is pre-treated through the filter net 34 in the filter box 31, and the larger material is pre-filtered to prevent the larger material from entering the disc filter 11, resulting in equipment overload during the operation of the disc filter 11, thereby affecting the filtering and dehydration effect and efficiency.
