Recycled concrete waste recovery device

Abstract

The invention relates to the field of concrete recovery, in particular to a recycled concrete waste recovery device. The recycled concrete waste recovery device comprises a vertically-arranged supporting mounting barrel. Multiple supporting mounting columns are arranged at the lower end of the supporting mounting barrel by the equal angle. A feeding mounting barrel is vertically arranged at the middle position of the upper end of the supporting mounting barrel. A crushing and guiding barrel is vertically arranged at the middle position of the bottom of the supporting mounting barrel. Multipledischarging gates are arranged at the position, corresponding to the crushing and guiding barrel, of the wall of the supporting mounting barrel by the equal angle. A guiding mounting barrel is vertically arranged at the middle position of the feeding mounting barrel. Through multi-stage crushing and screening, the crushing efficiency and quality of recycled concrete are improved remarkably, the crushing precision is adjusted through clearance adjusting, impurities are guided out during crushing and screening, the recovery quality of recycled concrete is improved, the material falling speed ofthe device is obviously increased in cooperation with vibration generated by rotating, and the recovery efficiency of the device is improved.

Description

technical field [0001] The invention relates to the field of concrete recycling, in particular to a recycled concrete waste recycling device. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete is widely used in civil engineering. In the process of concrete production, waste is easy to be generated. If the waste cannot be recycled in time, it will cause a waste of resources. [0003] However, the traditional concrete waste is generally collected first and then crushed. The crushed concrete powder is then transferred to the storage bucket. After the concrete i...

Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete is widely used in civil engineering. In the process of concrete production, waste is easy to be generated. If the waste cannot be recycled in time, it will cause a waste of resources.

[0003] However, the traditional concrete waste is generally collected first and then crushed. The crushed concrete powder is then transferred to the storage bucket. After the concrete is crushed, the discharge port of the crushing bucket needs to be manually opened, which is inconvenient to operate and low in recycling efficiency. , and the powdery waste poured from the crushing bucket is easy to fall between the storage bucket and the crushing bucket during transfer, resulting in waste of waste

[0004] Chinese patent (publication number CN209735740U) discloses a multi-functional waste recycling device for recycled concrete production. Although it can save manpower and facilitate the recycling and transfer of waste through internal crushing and transfer of transport boxes, the crushing structure is too simple. It often results in poor crushing quality, and there is no screening structure, resulting in poor quality of crushed concrete, and at the same time, it is impossible to adjust the crushing accuracy
