Manual Castings Sandblasting Room Vacuum Sandblasting Chamber Air Sand Blasting For Derusting Remove Paint
Main features:
5.2.4 Abrasives Distributing System
It’s a kind of sealed type pneumatic control gate valve developed independently developed by our company, control the itinerary and adjust blasting capacity, and effectively avoids motor burn, sand blaster jams, empty projection and wounding caused by normal control gate valve.
Principle Introduction:
| No | Comparison item | Honeycomb wind circulation sandblasting room | Traditional mechanical circulation sandblasting room
|
| 1 | Infrastructure
| 0.5-1.2 m or no foundation, low construction cost. . | 2.5-4 m deep pit, high waterproof requirements, foundation construction costs are several times higher than pneumatic recovery.
|
| 2 | Abrasive | Abrasive sorting There is separate sand returning fan. The cyclone separator is used to sort the abrasive. The particle size can be adjusted accurately, and the dust is large.
| There is no separate return sand blower, and the suction pipe is used for vacuuming. The particle size of the abrasive cannot be adjusted, and the air volume of the dust is not easy to be enlarged, and the sprayed abrasive is not uniform;
|
| 3 | The over-all layout | beautiful, the floor space is small, and the installation is convenient. Since all the equipment are connected by pipes, the installation positions of each system can be installed at will according to the site conditions.
| Each transmission system needs to be closely coordinated, it is impossible to change the installation position, the floor space is large, and the maintenance is inconvenient.
|
| 4 | Abrasive accumulation in the sand return system Abrasives | remaining in the sand return system and fewer Abrasives
| remaining in the sand return system, such as screw conveyors, bucket elevators and other equipment will accumulate a large amount of abrasive
|
| 5 | Occupational safety and environmental protection | The overall sand-absorbing and dust-absorbing floor, the wind flow from top to bottom, the dust suppression environment, dust content, visibility, dust emission are better than the national standard.
| Because the underground material needs to be installed with sand conveying equipment, the suction method is generally sucking up. The wind or side suction forms a dusty environment with high dust content, low visibility, and poor working environment.

5.2.5 Dust collection system
The Dust Collecting System includes filter cartridge dust collector, air blower and duct and connecting ducts between dust collector and main machine.
Secondary dust collecting Model: primary dust removal is steel shots setting chamber on the top of equipment. The
settling chamber is an inertial settling chamber complying with the aerodynamic principle, which enables the effective settlement of abrasives and without any pressure loss. One-way valve to prevent pneumatic conveying on the bottom of setting chamber, can effectively achieve abrasives setting. Purpose of this level of dust collecting is to clean pipeline
suction sand.
Secondary dust collecting system is economical and practical bag type dust collector. It uses Venturi tube pulse backflush cleaning system, with high filtration rate, high filtration accuracy, and good cleaning effect. Dust removal efficiency 99.9%, emission≤85mg/m3.
