In 2018, we received a request for an abrasive blasting chamber from Nikolai Nikolayevich, the owner of the Bador company, which is engaged in the production of a variety of semi-trailers and bodies for vehicles. As a cabin for this chamber, the existing structure of the Customer with an internal size of 15x6x6m is used, and we installed a set of equipment for the automatic collection and regeneration of abrasive material, as well as a ventilation and dust removal system.
Automatic fraction collection is carried out using a slatted floor, which has 6 longitudinal modules 15 m long, and one transverse module, which is located in the middle of the longitudinal ones. Longitudinal modules scrape off abrasive and dust from the chamber floor and direct them to the transverse module, while the transverse directs the fractions to the paternoster elevator.
The fractions reuse system consists of a bucket conveyor elevator, fractions separator and storage. The assembled paternoster elevator has a height of 7500 mm, with the help of a gear motor and a belt with buckets, the paternoster elevator raises the fractions and dust from the excavation to a height of 7 meters, after which the fractions are poured to the separator. The separator collects large particles of contaminants and dust from the fraction which is suitable for further use and feeds the fraction into the storage hopper. The storage hopper is a capacity containing up to 1 m3 of fractions, through it the shot is fed to the abrasive blasting machines in semi-automatic mode.
The ventilation and dust removal system is presented in the form of a filter-ventilation unit with 27 filter cartridges. A powerful centrifugal ventilation unit, with a productivity of 27,500 m3 / h, ensures the active removal of dusty air from the chamber. The ventilation unit is equipped with an automatic system for cleaning filter cartridges using reverse compressed air flows.
