Screw roller screen for separating concrete to recycle gravels

Abstract

The invention relates to the technical field of roller screen equipment, in particular to a screw roller screen for separating concrete to recycle gravels. The screw roller screen comprises a roller,a driving mechanism, a discharge chute and a receiving groove. Screw blades and a plurality of material lifting blades are arranged in the roller. The screw blades are arranged around the inner wall of the roller and drive materials to be pushed to a discharge port during rotating of the roller. The material lifting blades are arranged on the inner wall, close to the discharge port, of the rollerin an encircling mode. The discharge chute is obliquely arranged outside the discharge port of the roller. The receiving groove communicates with the discharge chute and is embedded in the roller fromthe discharge port. The material lifting blades drive the materials to go up from a low place and fall at a high place to go into the receiving groove during rotating of the roller. Through cooperation of the material lifting blades, the receiving groove and the discharge chute, the screw roller screen discharges the separated and output material from the high place, improves the stacking heightof the materials, improves the working efficiency without addition of extra equipment and is small in occupied area.

Description

technical field [0001] The invention relates to the technical field of rolling screen equipment, in particular to a spiral rolling screen for separating and recovering sand from concrete. Background technique [0002] Concrete sand and gravel separation roller screen is the core component of concrete recycling equipment, mainly used to clean, separate and recycle the sewage after cleaning the tank truck pump truck and the sand and gravel of concrete. The existing roller sieve separates the stones and discharges them from the roller sieve. The discharged stones need a certain space for accumulation. Generally, the outlet of the roller sieve is located at a lower position, and the stones cannot be stacked higher, so the outlet can be stored The amount of stones is small, and a forklift is required to carry out frequent shovel transfers; in order to solve the above problems, the usual solution is to additionally equip belt conveyors and other equipment to transport the stones d...

Problems solved by technology

The existing roller sieve separates the stones and discharges them from the roller sieve. The discharged stones need a certain space for accumulation. Generally, the outlet of the roller sieve is located at a lower position, and the stones cannot be stacked higher, so the outlet can be stored The amount of stones is small, and a forklift is required to carry out frequent shovel transfers; in order to solve the above problems, the usual solution is to equip additional belt conveyors and other equipment to transport the stones discharged from the discharge port to a high position in real time to increase the accumulation height of the stones. This kind of scheme needs to add additional equipment, which increases the equipment cost. At the same time, the layout of the belt conveyor also needs to occupy a certain space, which also increases the floor space of the equipment.
