Description
Technical Field
The utility model belongs to the technical field of machine-made sand, and particularly relates to a machine-made sand screening device for recycling construction waste.
Background
The construction waste treatment mainly comprises three main categories: one is waste bricks and tiles, waste sand and stone materials and other materials; secondly, raw materials such as waste plastics, waste steel materials and the like which can be recycled and utilized; thirdly, solid waste with relatively low utilization value, such as wool garbage. Among them, waste bricks, tiles and sand are difficult to solve in construction waste disposal, and have been deposited and landfilled for a long time without good disposal methods until machine-made sand is vigorous.
The construction waste is crushed into machine-made sand by adopting sand making equipment, and the machine-made sand is applied to various fields according to the quality of sand stone products, so that the problem of construction waste treatment and accumulation is solved, and huge social and economic benefits are added. According to the Chinese sand association and Chinese sand aggregate net, the following is displayed: each hundred million tons of construction waste is treated by recycling regeneration treatment, and 1000 ten thousand tons of regenerated bricks 243 hundred million standard bricks and regenerated aggregates can be produced and manufactured.
The machine-made sand is rock, mine tailings or industrial waste residue particles with the particle diameter of less than 4.75mm, which are obtained by crushing and screening by mechanical equipment through dust removal treatment, but does not contain soft and weathered particles, and is also called artificial sand.
The machine-made sand often has sand with different rules and sizes in the manufacturing process, and the sand with different rules and sizes is required to be different in different processes, so that the machine-made sand after the processing needs to be screened and classified. The sand sieving machine is one kind of mechanical equipment comprising sieving mechanism, power unit and material inlet and outlet. The sand screening machine screens out particles with a particle size smaller than that of the screen holes by utilizing the relative movement of the screen surface and the clastic materials.
However, the existing machine-made sand screening device can only screen out machine-made sand meeting the requirements in the use process, the machine-made sand not meeting the requirements can only be stored in the screening device, and the machine-made sand can only be taken out through subsequent manual work after the screening device overflows, so that time and labor are wasted; in addition, when the existing machine-made sand screening device is used, dust and smaller particles in the machine-made sand can float in the air due to vibration caused by screening, so that the surrounding environment of the screening device is poor, and the physical health of users is affected.
