Description
- This disclosure relates to a paint stripping system and method of use.
- Methods for stripping paint from a metal surface have evolved over the years. Abrasive blasting is one of the popular methods known in such industry. Abrasive blasting method is performed by forcibly propelling a stream of abrasive material, such as shot and grit, to smoothen the selected surface. One of the popular devices used for abrasive blasting is a blasting cabinet. This method allows the user to blast a material within the blasting cabinet. Such method can be effective in recycling the abrasive material used. Moreover, using such method can contain the abrasive material, dust, and other particulates within the blasting cabinet. Thus, such method can keep the waste contained and can prevent contaminating the environment. However using such method can be restrictive to the size of the blasting cabinet and cannot be used to blast a larger object. Moreover, such method is usually kept at one place and is not mobile. Another method used for blasting is pressure blaster, which can be used to blast large objects and/or surfaces. In such methods, the abrasive material is released from a nozzle towards the selected surface. Thus, this method can be expensive, as it does not support recycling of abrasive material used. Additionally it can be inconvenient to use such method when blasting overhead surfaces. As such it would be useful to have an improved paint stripping system and method of use.
- A paint stripping system and method of use is described herein. The paint stripping system can comprise a blaster, a buggy, and a dust collector. The blaster can comprise an upper seal, one or more propeller assemblies, one or more recirculators, and one or more motor assemblies. The upper seal can be at the top surface of the blaster. The upper seal can be positionable under an overhead surface such that waste materials and abrasive material that is produced during operation is collected within the blaster. The propeller assemblies can be mounted within the blaster. The propeller assemblies can propel the abrasive material towards the overhead surface. The recirculators can recycle collected abrasive material. The motor assemblies can actuate the propeller assemblies. The buggy can mount the blaster. The buggy can comprise a scissor lift, and a steering system. The scissor lift can be adjusted such that the upper seal is directly under the overhead surface. The steering system can maneuver the blaster to a desired direction. The adjust collector can be connected to a portion of the blaster through a vacuum hose. The dust collector can receive the waste material collected from the blaster.
- A method for operating a paint stripping system is described herein. The method can comprise the steps of maneuvering a buggy under an overhead surface through a steering system, loading an abrasive material within a blaster, adjusting a scissor lift such that the blaster can be positioned under the overhead surface, and turning on an air compressor within a dust collector to start blasting the overhead surface. The buggy can comprise the scissor lift. The blaster can be mounted on top of the scissor lift. The dust collector can connects the blaster through a vacuum hose and an air supply hose.

After the debris is filtered through vacuum pump and filter 1505, the collected waste can be dumped into the waste container ofdust collector 103. Once the waste container is full, the waste container can be removed to dispose the debris. - Simultaneously, the abrasive material produced during operation can be recovered within
second enclosure 302 and then goes back to each recirculator 500 to be recycled. As the abrasive materials is sent back intorecirculator 500, the abrasive material can curve aroundfirst enclosure 301 and be thrown towards the center.Deflector shield 1001 ofdust vent 303 can slow down the momentum of the abrasive material. The gravity can then help facilitate with refeeding the abrasive material intopropeller assembly 600. In some cases wherein some obstacle prevents the abrasive material from being recycled, the abrasive material can collect withinbottom cavity 504 and withingaps 702. Whenpaint stripping system 100 needs new abrasive material,third loader valve 1203 c onshot box 1201 can load additional abrasive material tofirst enclosure 301. - Various changes in the details of the illustrated operational methods are possible without departing from the scope of the following claims.
