Feeding device for construction waste recycled aggregate production

Abstract

The invention discloses a feeding device for construction waste recycled aggregate production. The feeding device comprises a feeding conveying belt, a discharging conveying belt, a support, a crushing mechanism and a distributing mechanism, wherein the feeding conveying belt is fixed to the support, the discharging conveying belt is fixed to the support and located above the feeding conveying belt, the crushing mechanism is located on one side of the feeding conveying belt, and the material distributing mechanism is located on the feeding conveying belt. Impact of concrete blocks on the crushing mechanism can be effectively avoided by feeding from the lower portion, and the service life of the crushing mechanism is effectively prolonged; and concrete blocks with steel bars and concrete blocks without steel bars are separated and then are crushed respectively, and energy is effectively saved.

Description

technical field [0001] The invention relates to the technical field of construction waste recycling, in particular to a feeding device for the production of construction waste recycled aggregates. Background technique [0002] As the environmental protection situation becomes increasingly severe, the state gradually strengthens the control of sand and gravel aggregates, which leads to a sharp rise in the price of sand and gravel aggregates, and even a shortage of aggregates. If you want to produce normally and obtain better operating results, Alternatives to conventional aggregates must be sought to ensure a stable supply of raw materials. Recycled aggregate from construction waste belongs to solid waste resources. In the current era of large-scale demolition and large-scale construction, the reserves of construction waste are astonishing.

Recycled aggregate from construction waste belongs to solid waste resources. In the current era of large-scale demolition and large-scale construction, the reserves of construction waste are astonishing. After crushing construction waste, it can be used as recycled aggregate for various infrastructures. The garbage is put into the crusher for crushing to achieve the required particle size aggregate. The construction waste is put into the crusher. Generally, the conveyor belt is directly dropped into the crusher from the top of the crusher. The volume of construction waste varies, and some construction waste is heavier. Large, falling into the crusher from a high place is easy to cause damage to the crusher; since construction waste is generally concrete blocks, some of which contain steel bars, breaking concrete blocks with steel bars requires a more powerful crushing mechanism, and the existing technology will contain Steel bars are broken together with construction waste that does not contain steel bars, resulting in waste of resources
