Description

Technical Field

[0001] The utility model relates to the technical field of chip conveyors, in particular to a backwashing chip conveyor. Background Art

[0003] Existing backwash chip conveyors, such as a composite backwash chip conveyor disclosed in the invention patent with application number 202310602232.3, have a main structure including a collection box, a transport device arranged inside the collection box, and the other end of the transport device extending to the outside of the collection box, a support frame symmetrically fixedly connected to the outer wall of the transport device, a scraper fixedly connected to the outer wall of the transport device at equal distances, and a shielding plate fixedly connected to the outer wall of the transport device; when in use, first place the waste chips on the top of the transport device, and at this time the transport device can transport the waste chips into the collection box through the cooperation of the scraper and the shielding plate The cutting fluid flows into the collection box, at which time the waste chips and cutting fluid fall into the first collection tank. Then, when the height of the cutting fluid reaches the height of the filter plate, the cutting fluid passes through the filter plate and enters the second collection tank. As the cutting fluid flows in, some of the debris is blocked on the surface of the filter plate. At this time, the user can turn on the water pump to work. The water pump draws the cutting fluid from the second collection tank through the suction pipe, and then sprays it into the water collection tank through the drain pipe. The cutting fluid will then be sprayed to the outer wall of the transport device through the first nozzle, thereby cleaning up some of the debris accumulated on the outer wall of the transport device.
