Description

Technical Field

[0001] The utility model belongs to the field of steel bar recycling and processing equipment, and particularly relates to an integrated device for cleaning, straightening and derusting steel bars used in construction. Background Art

[0002] With the continuous development of construction projects, steel bars, as the skeleton of concrete, have become the main material with the widest application and largest quantity in building structures.

[0003] Furthermore, with the acceleration of urbanization and the improvement of people's living standards, the construction, renovation, expansion, and demolition of buildings generate a large amount of waste building materials throughout the construction process. Among these waste building materials, the main recyclable resource is scrap steel. However, because the scrap steel generated by demolition often contains large chunks of concrete and is severely bent and deformed, traditional manual processing is not only complex but also ineffective, resulting in a waste of labor and materials.

[0004] Given the limitations of current steel bar recycling technology, the demand for improvements in steel bar recycling and processing equipment has become increasingly urgent. That is, a simple mechanical equipment is urgently needed to replace the traditional purely manual cleaning and adjustment methods, so as to improve the cleaning effect of scrap steel bars, save labor costs, and increase the reuse rate of scrap steel bars. Utility Model Content

[0005] The technical problem solved by the utility model is to provide an integrated device for cleaning, straightening and rust removal of construction steel bars with a simple structure and convenient operation, so as to replace the traditional purely manual cleaning and adjustment method to mechanically straighten, clean and rust-remove scrap steel bars, thereby improving the cleaning effect of scrap steel bars, saving labor costs, and further increasing the reuse rate of scrap steel bars.

When using the present invention to process scrap steel bars, the scrap steel bars can first be squeezed by the cooperation between the pressure plate and the bearing plate at the hydraulic crushing unit to crush the concrete fragments adhered to the surface of the scrap steel bars. Then, the scrap steel bars are squeezed and straightened by the straightening rollers at the straightening frame, and rust removed by the rust removal mechanism at the rust removal frame, thereby meeting the basic processing requirements for scrap steel bars.

[0007] Furthermore, a lifting mechanism is provided below the carrying platform, and the height of the carrying platform is controlled and adjusted by the lifting mechanism to adapt to the size of concrete fragments carried on the surface of the scrap steel bars.

The connecting column passes through the straightening frame and is threadedly connected to an adjusting nut. The distance between the two straightening rollers in the same pair of straightening rollers can be adjusted by adjusting the relative position relationship between the adjusting nut and the connecting column to adapt to the diameter of the scrap steel bars.

[0011] Furthermore, the rust removal mechanism includes two sets of rust removal brushes symmetrically arranged in the rust removal frame, and the rust removal brushes are preferably steel brushes.
