Concrete preparation system for recycling waste concrete

Abstract

The invention relates to the technical field of concrete preparation, in particular to a concrete preparation system for recycling waste concrete. Comprising a supporting seat, a rotating box is fixedly arranged on the left side of the upper end face of the supporting seat, a rotating box cavity with a rightward opening is formed in the right end face of the rotating box, and moving racks which can move left and right and are vertically symmetrical are arranged on the upper side wall and the lower side wall in the rotating box; according to the device, the stirring motor rotates forwards and the transmission motor rotates backwards to drive the stirring gear in the cavity of the stirring box body to rotate forwards and drive the fixed grinding block to rotate backwards to achieve the grinding effect, and the grinding effect is achieved through repeated cooperation, so that the effect that concrete stones are thoroughly separated into stones and building sand is achieved; the problems that a large amount of land is occupied by the waste concrete and resources are greatly wasted are solved, and the cost is greatly saved by using the waste concrete blocks.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to a concrete preparation system for recycling waste concrete. Background technique [0002] Concrete is the most important material in civil engineering. With the increasing scale of construction, the amount of concrete used has risen sharply, and at the same time, a large amount of commercial concrete waste is also increasing every year. At present, the treatment method of concrete waste is generally transported to the suburbs for open-air stacking or landfill, which not only occupies a large amount of land, but also causes a great waste of resources. [0003] The current technology for the application of waste concrete in the construction field cannot completely separate the sand and gravel components in the waste concrete, and basically simple crushing is used to make recycled aggregate, so as to replace part of the coarse aggregate in concrete. Because the waste c...
