This invention discloses a dust-proof and environmentally friendly construction waste recycling device in the field of construction waste recycling technology. It includes a magnetic mechanism and a crushing mechanism inside the outer shell. The crushing mechanism includes a cylindrical lifting block with multiple open cylindrical lifting block grooves at its bottom. The magnetic mechanism includes a cross-shaped magnetic suction frame. Both the lifting block grooves and the cross-shaped magnetic suction frame have independently controlled electromagnets built into them. This invention uses the magnetic suction mechanism and the crushing mechanism to lift and drop the cylindrical lifting block onto the concrete, effectively crushing it. Then, by raising the cross-shaped magnetic suction frame from the cylindrical lifting block and rotating it, the top layer of concrete is dispersed, and metal waste in the concrete is adsorbed layer by layer. This process is repeated until all the metal waste in the concrete is adsorbed, solving the problem of separating concrete and metal waste through crushing.

The utility model discloses a hardware calendering device relates to hardware calendering technical field, and the calendering device includes: base, is fixed with support on the base, is equipped with multiple groups of the compression roller for carrying out calendering to hardware products on the support through the elevating system, is equipped with the cleaning dust collection mechanism for cleaning the surface of compression roller and hardware products on the elevating system and the lateral side of support, and is equipped with the heating piece elevating system for carrying out heating to hardware products during calendering below the compression roller on the base, and the installation plate is installed through the elevating piece and can go up and down along the vertical direction, and multiple groups of the compression roller of fixed mounting are installed on the installation plate through the fixed frame and are arranged in parallel, and the cleaning dust collection mechanism is equipped on the limiting block. When using the device, the outer wall of the calendering roller is easy to contaminate the metal scrap in the process of carrying out the calendering operation to the steel plate in the prior art, which will affect the quality of the calendering of the steel plate and easily cause the problem of error.
