[0020] The conveying mechanism 4 includes a conveying frame 41, which is connected to the inner side of the support frame 1, one end of the conveying frame 41 is connected to a rotating shaft 42, and the other end is equipped with a driven shaft 45, one end of the rotating shaft 42 is connected to a motor 43, the motor 43 is connected to the right end of the support frame 1, and the motor 43 is connected to the controller 9, a mesh-shaped filter conveyor belt 44 is provided on the conveying frame 41, and is tensioned by the rotating shaft 42 and the driven shaft 45, the filter conveyor belt 44 corresponds to the position of the coolant collection port 3, a liquid leakage port 10 is provided on the lower side of the liquid collection box 7, a valve 11 is installed at the lower end of the leakage port 10, and a recovery tank is provided at the lower end of the leakage port 10 12. The net bag 6 is connected with a card slot 61, and the card slot 61 is connected with a handle 62. The card slot 61 corresponds to the upper side of the metal collection box 5 and cooperates with each other. When the metal debris in the metal collection box 5 is full, the handle 62 is lifted up to take the net bag 6 out of the metal collection box 5.

The rear side of the filter conveyor belt 44 corresponds to the upper side of the metal collection box 5, and the front side of the metal collection box 5 corresponds to the position of the liquid collection box 7, so that the metal debris in the coolant can be filtered out conveniently.
[0021] Working principle: The metal workpiece is cut, drilled, polished, etc. on the operating table 2. In order to cool the tool inside the machine tool, the coolant is sprayed on the high-speed rotating tool. Therefore, the metal debris generated when the CNC machining center processes the metal workpiece is wrapped by the coolant and falls from the coolant collection port 3 onto the filter conveyor 44. The motor 43 is turned on on the controller 9. The motor 43 works to drive the filter conveyor 44 to drive the metal debris output by the preliminary filtration to move backward until it falls into the net bag 6 in the metal collection box 5. The coolant initially filtered out by the filter conveyor 44 drips into the liquid collection box 7. The controller 9 controls the electromagnet 8 to work. The electromagnet 8 collects small metal particles in the coolant that are not easily filtered out. The valve 11 is opened and the filtered coolant flows along the leakage port 10 to the recovery tank 12. At this time, there is no metal debris in the coolant in the recovery tank 12, which is convenient for secondary utilization and there is no need to worry about environmental pollution during discharge.
