[0014] Beneficial Effects

[0015] The beneficial effects of the utility model are:

[0016] When there is coolant wastewater that needs to be filtered, workers do not need to perform salvage work, but directly pour the wastewater into the space between the coarse filter layer and the core rod. The coarse filter layer is made of an iron filter mesh, which can block large metal scraps and allow smaller metal scraps to flow between the fine filter layer and the dense filter layer. Since the filtration accuracy of the fine filter layer is higher than that of the coarse filter layer, the metal scraps that are not filtered by the coarse filter layer are blocked by the fine filter layer, so that the wastewater with granular metal scraps flows to the space between the dense filter layer and the fine filter layer, and is driven by the rotating component. The filter element rotates. During the rotation, the wastewater is subjected to the action of centrifugal force. The wastewater between the dense filter layer and the fine filter layer passes through the dense filter layer. The granular metal debris in the wastewater is blocked by the dense filter layer made of canvas material, and the remaining wastewater enters between the dense filter layer and the inner wall of the filter chamber. When the filtration is completed, it is discharged from the filter chamber through the outlet pipe and enters the wastewater purification treatment link, replacing the workers to salvage and recover the metal debris in the wastewater, and the filtering effect of the metal debris is better, thereby reducing the labor intensity of the workers and improving the salvage and recovery effect of metal debris and metal waste.

[0029] A specific application of this embodiment is:

[0030] When filtering is required, the worker first closes the valve 61 of the outlet pipe 6, and then pours the wastewater to be filtered into between the core rod 21 and the coarse filter layer 22. The sealing plate 3 receives the wastewater, and the matching groove 31 facilitates the close connection between the coarse filter layer 22, the fine filter layer 23 and the dense filter layer 24. Then, the plugging disk 3 is driven to rotate by rotating the motor 42 through the rotating shaft 421, the connection column 45 and the connection hole 44 cooperate to drive the plugging disk 3 to rotate synchronously, the connection assembly 5 drives the core rod 21 to follow the rotation, and the core rod 21 drives the coarse filter layer 22, the fine filter layer 23 and the dense filter layer 24 to rotate synchronously through the connecting rod. Since the dense filter layer 24 bears the pressure of the wastewater and there are metal wastes in the wastewater, the wastewater can follow the rotation and generate centrifugal force. The wastewater is accelerated to filter under the action of centrifugal force. The coarse filter layer 22, the fine filter layer 23 and the dense filter layer 24 block metal wastes of different volumes. When the valve 61 of the outlet pipe 6 is opened, the wastewater is discharged into the purification link for purification, and the metal wastes can be blocked on the plugging disk 3. After the wastewater is discharged, the worker can directly take out the plugging disk 3 and the filter element 2 together by holding the core rod 21, and then separate the filter element 2 and the plugging disk 3 to take out the filtered metal wastes. In summary, through the above steps, the labor intensity of workers can be reduced and the effect of salvaging and recycling metal debris and metal waste can be improved.
