Sandblast cabins, containers

In the cabin, steel parts and welded structures receive surface treatment (cleaning) through grit and sand blasting.

The blasting is done with a manual compressed air blaster. The cabin’s structure consists of panels, with one or two doors (as requested), and a proper interior protection from wear. The working area is lit with security light fixtures mounted on the ceiling of the blast cabin.

The sandwich panel built in the cabin’s steel structure has side and roof panels. The lights providing illumination for the cabin and the nozzles supplying the feedback of the cleaned air are installed on the ceiling.

The blast cabin includes the supporting parts required for the installation of the rubber wear protection. The entire inner surface of the blast cabin is covered by fabric reinforced rubber sheets.

The floor of the working area can be flat sheet cladding, then the grits are collected into a grit collector manually, or it can be automated. In case of automation, the floor of the working area is covered by grating and a scraper-floored grit colleting system is located below it. This system delivers the sprayed particles into the collector. The grit collector delivers the blast material to the feed bucket elevator and the feed bucket elevator delivers it to the blast material cleaner.

In the blast material cleaner, the worn grits are selected from among the cleaned grits, as well as any scale or oxide residues and other impurities that were separated from the surface of the cleaned parts.

The cleaned material is collected in the feeding buffer tank, which can be returned to the compressed air tank through the feeding sector lock. The dust generated by the blasting is exhausted by an exhaust fan. The exhausted air is cleaned by fine filter equipment. Dusty air is not returned to the environment. The complete cleaning cabin is controlled from a separate control cabinet.

A blast cabin may consist of the following main and auxiliary units:

  • blast cabin’s structure

  • entrance gates and personal entrance doors

  • the working area’s wear-resisting rubber sheet coating

  • scraper-floored grit colleting system

  • grating

  • feed bucket elevator

  • blast material cleaner

  • buffer tank

  • dust separator system

  • compressed air spraying

  • protective clothing, blast helmet with rectangular or panoramic glass supplied with fresh air; cooling and heating air-conditioning unit that can be connected to the helmet

  • control cabinet and controls
