Aiming at the technical scheme, the recovery sieve adopts a double-layer sieve structure, the lower layer is a stone aggregate screening sieve, the upper layer is a sand aggregate screening dehydration sieve, the stone aggregate and the sand aggregate are respectively screened and drained, the stone aggregate and the sand aggregate are integrated, the occupied area of equipment is small, and the production cost is reduced; vibrating motor and spring support mutually support and improve the vibration screening effect of retrieving the sieve.
Preferably, the two vibration motors are arranged in parallel, and the vibration motors are positioned at one end of the discharge hole. The high frequency dual motor design can ensure that the recovery screen has a greater throughput.
Preferably, the sand aggregate screen and the stone aggregate screen are respectively provided with a flushing pipeline, a spray head is arranged on the flushing pipeline, and the flushing pipeline is connected with an external water storage tank. In the production process, the washing pipeline is used for washing the materials flowing on the screen mesh to ensure that the screened aggregates are clean; after production is finished, the screen is directly cleaned by the flushing pipeline, so that the screen is ensured to be clean, and the adhesion and condensation of slurry are avoided.
Preferably, the side of the upper part of the support frame is of a triangular structure, and the vibration motor is arranged at the vertex angle of the triangle. Can guarantee vibrating motor's height, can reduce the height of feed inlet again, under the prerequisite of guaranteeing the vibration effect, conveniently reinforced.
Preferably, the sand aggregate screen and the stone aggregate screen are polyurethane screens. The polyurethane screen has the advantages of high smoothness, high elasticity, low adhesion and easy cleaning.
The utility model has the advantages that:
the utility model adopts the double-layer screen integrated recovery sieve, which has low manufacturing and using cost, small occupied area and good sieving effect; the aggregate is cleaned by additionally arranging the flushing pipeline, the screen is cleaned in time, and the screen is not easy to block; the screen cloth is obliquely arranged, so that the aggregate can be more thoroughly separated, and the screen cloth can be directly used for production.
