Concrete gravel separation and recovery device

Abstract

The invention discloses a concrete gravel separation and recovery device. The device comprises a main box body, a gravel separation module, a feeding box, a gravel screening module and damping modules. According to the device, the structure is reasonable in design, and the practicability is high; during work, spraying heads spray water on raw materials, spraying is uniform, and the cleaning effectis better; a second motor drives a first belt wheel and a second belt wheel to rotate through a driving belt wheel so as to drive a second rotating shaft, a first V-shaped screening plate, a third rotating shaft and a second V-shaped screening plate to rotate left and right within a short distance, meanwhile, gravel can be effectively filtered and classified under the action of a vibration motor,the filtration effect is good, and the filter screen is not prone to blockage; and under the action of a coarse-hole filter screen and a fine-hole filter screen, the gravel can be effectively collected in a classified mode, the gravel can be recycled, and waste is reduced; and device resonance is prevented under the action of the damping modules, so that the influence of the vibration motor on the whole device is reduced, the main box body can also effectively isolate noise, and meanwhile, the device is elegant and attractive.

Description

technical field [0001] The invention relates to the technical field of building construction environmental protection equipment, in particular to concrete sand and gravel separation and recovery equipment. Background technique [0002] A large amount of waste water and waste residues are produced during the production of ready-mixed concrete. These waste water and waste residues are usually discharged directly without treatment, causing great pollution to the environment. The existing concrete cleaning and separation equipment has limited separation effect on solids and liquids, and it is difficult to completely separate them Sand and stone, not only cannot complete the recycling of sand and stone, but also cannot realize the recycling of slurry water, sand and stone, which wastes resources and pollutes the environment. Disposal of excess concrete and exhausted concrete that cannot be used due to quality problems. [0003] At present, most of the existing concrete sand and ...

Problems solved by technology

[0002] A large amount of waste water and waste residues are produced during the production of ready-mixed concrete. These waste water and waste residues are usually discharged directly without treatment, causing great pollution to the environment. The existing concrete cleaning and separation equipment has limited separation effect on solids and liquids, and it is difficult to completely separate them Sand and stone, not only cannot complete the recycling of sand and stone, but also cannot realize the recycling of slurry water, sand and stone, which wastes resources and pollutes the environment. Disposal of redundant concrete and exhausted concrete that cannot be used due to quality problems, etc.

[0003] At present, most of the existing concrete sand and gravel separation and recovery equipment have single functions, and can only perform preliminary separation of sand and gravel, and the separation effect is poor. At the same time, the sand cannot be further subdivided, which is not conducive to efficient recycling. The recovery equipment is equipped with shock-absorbing components, so the vibration generated during the separation of sand and gravel is likely to have a negative impact on the life of the entire device. Finally, the existing sand and gravel separation and recovery equipment is noisy, the working environment is poor, and it is not beautiful enough.
