the sewage which slips down flows into the water collecting box 14 through the water filtering net 1601 on one side of the adapter plate 16, the sewage in the water collecting box 14 is purified through the inclined filtering net 15 and then flows to the purified water collecting box 10, the purified water which is purified flows out through the purified water outlet 11 at the bottom of the purified water collecting box 10, and the flowing purified water is sent into the next-stage rinsing machine through the water suction pipe arranged on the purified water outlet 11 and is pumped by the external water pump, so that the purpose of reusing the sewage is realized; after the filtration starts, objects such as powder, silt and the like begin to appear on the filter screen 15, during continuous filtration, the powder, the silt and the like slide to the residual solid discharge port 12 along the inclination angle of the filter screen 15 and begin to accumulate on the residual solid discharge port 12, after a period of waste plastic fragment cleaning, a sealing cover arranged on the residual solid discharge port 12 can be opened to clean the objects such as the powder, the silt and the like, and the cleaning machine does not need to be stopped during the cleaning process; after a period of filtration, the filtering speed of the filter screen 15 is reduced, the operation of the flushing machine is stopped, the front access cover 13 is opened, an operator replaces or thoroughly cleans the filter screen 15, and the filter screen 15 is detachably connected with the water collecting box 14; when the main body 1 needs to be overhauled, the rear access cover 9 can be opened to overhaul the internal parts of the main body or clean the residual waste plastic fragments between the water filtering net 1601 and the rear access cover 9.
Example 2:
a continuous waste plastic scrap developing machine is shown in FIG. 6, and is different from example 1 in that: an outward-inclined plate 1602 is arranged at the top end of the joint of the adapter plate 16 and one side face of the main body 1; through setting up camber plate 1602 for have great clearance between this side of main part 1 and nozzle group 19, 2, 3, make things convenient for waste plastics piece to fall to keysets 16 through this clearance, reduce the possibility that waste plastics piece falls to conveyer belt 8 through the clearance between nozzle group 19, 2, 3, prevent that waste plastics piece from not having to wash many times and falling into next process.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, but rather as the following description is intended to cover all modifications, equivalents and improvements falling within the spirit and scope of the present invention.
