501, chalk end can be thrown into sedimentation fermentation vat 501.The chalk waste that three cases above is collected can enter sedimentation leaching
Pond 501 is steeped, after being soaked for a period of time in settling fermentation vat 501, chalk waste will become pulp.Pass through the first water pump 502
The water settled in fermentation vat 501 is pumped into pond 503, slurry-supplying valve is then opened, so that slurry is entered slurry and dries in the air pond 5051 processed, slurry
The material slurry in pond 5051 processed that dries in the air dried in the air after a period of time, and slurry moisture is reduced, and slurry becomes sticky, then rotates slurry pressing assembly
5053 handle 50534, makes briquetting 50533 move downward, opens simultaneously discharge valve, and slurry is made to be pressed into chalk forming box
5052, new chalk can be formed by being poured out after chalk dries in chalk forming box 5052.The water used during wet rubbing
From pond 503, the water after use is able to reuse that by sedimentation and extraction, so as to recycle.Therefore this hair
The waste that bright novel environment protection blackboard system 10 generates is considerably less.By wet rubbing and xerotripsis, the dust contained in air is also very
Few, the body during 30 that erases the board hardly touches dust, therefore reduces the number of cleaning hand or hair, to save
Water resource.
The operation of the novel environment protection blackboard system 10 of the present invention is fairly simple, while need not consume excessive electric power and carry out
Driving does not need complicated control system yet and is controlled, therefore practicability is stronger, is easy expanded.
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, those skilled in the art can understand all or part of the processes for realizing the above embodiment, and is wanted according to right of the present invention
Equivalent variations made by asking, still belong to the scope covered by the invention.
