Shot blasting is an effective way to remove deteriorated coatings, clean the surface, and prepare it for new protective coatings. This helps in extending the lifespan of these structures and ensuring the safety of users.
Features
1. High - Efficiency Cleaning
Floor shot blasters are designed to clean large floor areas quickly and efficiently. The high - velocity impact of the abrasive media allows for rapid removal of even the most stubborn contaminants. Some models are equipped with wide - width blasting heads or multiple nozzles, which can cover a larger area in a single pass, reducing the overall cleaning time. For example, in a large industrial hall, a floor shot blaster with a 1 - meter - wide blasting head can clean hundreds of square meters in a day.
2. Adjustable Blasting Parameters
These machines offer a high degree of adjustability in terms of blasting pressure, media flow rate, and machine speed. Operators can customize these parameters based on the type of floor material, the level of contamination, and the desired surface finish. For instance, for a delicate tile floor, a lower blasting pressure and a slower machine speed can be selected to avoid damage, while for a rough concrete floor with thick coatings, a higher pressure and a faster speed can be used.
3. Uniform Surface Finish
The design of floor shot blasters ensures that the floor receives a uniform surface finish. The abrasive media is evenly distributed across the floor surface, resulting in a consistent removal of contaminants and a uniform texture. This is crucial for applications where a smooth and even surface is required for proper adhesion of coatings or for aesthetic reasons.
4. Abrasive Recycling System
Modern floor shot blasters are often equipped with an abrasive recycling system. After the abrasive media has been used to blast the floor, it is collected, separated from the debris, and recycled for further use. This not only reduces the cost of operation but also minimizes waste. The recycling system typically includes a series of screens, cyclones, and conveyors that work together to clean and sort the abrasive media. Some machines can achieve an abrasive recycling rate of up to 90%, making them highly cost - effective and environmentally friendly.
5. Mobility and Ease of Use
Floor shot blasters are designed to be mobile and easy to operate. They are often equipped with wheels or tracks, allowing for easy movement across the floor. The controls are typically user - friendly, with simple - to - understand interfaces that enable operators to start, stop, and adjust the machine settings with ease. Some models also come with features like self - leveling systems, which ensure that the blasting head remains at a consistent distance from the floor surface, regardless of any unevenness.
Components
1. Blasting Chamber
The blasting chamber is the core component of the floor shot blaster. It is where the actual blasting process takes place. The chamber is designed to contain the abrasive media and prevent it from escaping, ensuring a safe and efficient operation. It is usually made of thick - walled steel plates and may be lined with wear - resistant materials to withstand the continuous impact of the abrasive particles. The chamber has openings for the entry and exit of the abrasive media, as well as for the connection of the blasting nozzles or wheels.
2. Blasting Wheels or Nozzles
Blasting Wheels: In some floor shot blasters, rotating blasting wheels are used to accelerate the abrasive media. These wheels are driven by electric motors and have specially designed vanes that pick up the abrasive particles and throw them at high speeds onto the floor surface. The number and position of the blasting wheels can be adjusted to achieve the desired blasting pattern and coverage. For example, in a machine designed for large - scale floor cleaning, multiple blasting wheels may be arranged in a row to cover a wider area.
Nozzles: Other machines use nozzles to direct the abrasive media. Compressed air or a combination of compressed air and mechanical force is used to propel the media through the nozzles. The nozzles are made of wear - resistant materials, such as tungsten carbide, to withstand the high - velocity flow of the abrasive. They can be adjusted in terms of their angle, distance from the floor, and the size of the orifice through which the abrasive is ejected. This allows for precise control of the blasting intensity and direction.
3. Abrasive Feeding System
The abrasive feeding system is responsible for supplying the abrasive media to the blasting wheels or nozzles. It consists of a hopper, which stores the abrasive, and a feeding mechanism. The feeding mechanism can be a screw conveyor, a vibrating feeder, or a pneumatic feeder. The choice of feeder depends on the type of abrasive media and the requirements of the blasting process. The feeding system is designed to provide a consistent and adjustable flow of abrasive media to ensure a continuous and efficient blasting operation. Sensors are often installed in the hopper to monitor the level of abrasive media, and an automatic refill system can be integrated to prevent interruption of the blasting process due to low abrasive levels.
4. Dust Collection System
A dust collection system is an essential component of a floor shot blaster. During the blasting process, fine dust particles are generated, which can pose a health hazard and create an environmental nuisance. The dust collection system is designed to capture these particles and prevent them from being released into the air. It typically consists of a series of filters, cyclones, and fans. The fans draw in the air from the blasting area, which contains the dust particles. The cyclones first separate the larger particles, and then the remaining fine dust is captured by the filters. The collected dust is then removed from the system for proper disposal. Some advanced dust collection systems are designed to meet strict environmental regulations, ensuring that the emissions from the shot blasting process are well within acceptable limits.
5. Conveyor and Recovery System
The conveyor and recovery system is used to collect the used abrasive media and debris from the floor surface. It typically includes a conveyor belt or a series of rollers that move the used media and debris towards a collection point. The system may also include a separator, which separates the abrasive media from the debris. The separated abrasive media is then sent back to the hopper for recycling, while the debris is collected and disposed of. This system ensures that the blasting process can continue uninterrupted and that the abrasive media is used efficiently.
6. Power Unit
The power unit of a floor shot blaster provides the energy required to drive the various components of the machine. It can be an electric motor, a gasoline engine, or a diesel engine, depending on the size and application of the machine. The power unit is designed to provide sufficient power to accelerate the abrasive media, drive the blasting wheels or nozzles, and operate the conveyor and dust collection systems. It is also equipped with controls for starting, stopping, and adjusting the power output.
