Backpack type powder spraying room
Structural Features
1. Main Material: Backpack filter powder room is usually made of materials such as stainless steel or galvanized sheet to ensure the durability and easy cleaning of the equipment.
2. Filter Design: The powder room is equipped with a backpack filter. This filter design can be quickly replaced, which is convenient for switching between different colors of powder coatings.
Working Principle
1. During the spraying operation, powder is sprayed onto the workpiece through the spray gun, and the unattached powder is sucked to the surface of the filter by the exhaust system to achieve filtering and recovery.
2. When the powder passes through the filter, the larger powder particles hit the surface of the filter due to inertia and slide back to the powder supply system along the surface of the filter, while the fine powder is captured by the filter.
Filter Features
1. Filter Material: The filter usually uses anti-static and high-efficiency filter materials, such as polyester fiber or glass fiber, which can effectively filter fine powder while maintaining low wind resistance.
2. Convenient Replacement: The backpack filter is designed to be quickly replaced, which is convenient for the operator to switch between different colors or powder types.
Operation and maintenance
1. Convenience: Due to the design of the backpack filter element, the operator can quickly remove and install the filter element, thereby improving the maintenance efficiency of the equipment.
2. Cleaning: The interior design of the powder room is generally easy to clean to reduce powder residue and accumulation.
Safety and environmental protection
1. Safety measures: The backpack filter powder room is designed with operator safety in mind, such as anti-static design, and ventilation and recovery systems that meet explosion-proof requirements.
2. Environmental protection: The impact on the environment is reduced through effective powder recovery and emission purification.
Filtration Efficiency
1. The filtration efficiency of backpack filter elements is usually very high, which can capture tiny powder particles and reduce environmental pollution.
2. The design and material of the filter element have a direct impact on its filtration efficiency. For example, filter media with a surface coating can improve the filtration effect.
Maintenance and Replacement
1. After a period of use, the backpack filter element will need to be cleaned or replaced due to powder accumulation.
2. Cleaning is usually carried out by backblowing with compressed air to remove powder on the filter element.
3. When the filtration effect of the filter element decreases or is damaged, it is necessary to replace it with a new one in time.
Applicability
1. The backpack filter element powder room is suitable for small and medium-sized spraying operations.
2. It can replace the filter element, thereby achieving color change and improving production efficiency.
Preparation
1. Make sure the filter backpack powder room has been properly installed and all necessary pipes and power supplies are connected.
2. Check whether the compressed air supply is stable and whether the pressure meets the equipment requirements.
3. Check whether the backflush system is normal, including the backflush valve, pipes and timer.
Start the system
1. Start the ventilation system to ensure air circulation.
2. Turn on the spray gun and powder supply system and start spraying.
Backflush and dust removal
1. When the powder accumulated on the surface of the filter element reaches a certain level or the pressure difference reaches the set upper limit, start the backflush procedure.
2. Open the backflush valve and use compressed air to backflush the filter element to blow off the powder attached to the filter element.
3. After backflush for a period of time, close the backflush valve and wait for the powder in the filter element to fall back into the powder room or collection container.
Inspection and maintenance
1. After backflush, check the cleanliness and filtering effect of the filter element to confirm whether further cleaning or replacement of the filter element is required.
2. Check the working status of the backflush system regularly to ensure its normal operation.
3. Record the time and effect of backflush to provide reference for subsequent operations.
End of operation
1. After completing the spraying operation, turn off all systems and clean the work area.
2. Check and record the operation of the equipmen
Precautions and knowledge points for purchasing products
1. Filtration efficiency: Make sure that the filter element can efficiently filter particles in powder coating to maintain spraying quality and reduce waste.
2. Capacity and size: Choose the appropriate capacity and size according to your production needs, and ensure that the powder room can accommodate the required number of filter elements.
3. Material: The material of the powder room should be corrosion-resistant and able to withstand the chemical composition of powder coating. Stainless steel is usually a better choice.
4. Operation convenience: Check whether the filter element can be replaced easily and quickly, and whether the powder room is easy to clean and maintain.
5. Air circulation: Make sure that the powder room has a good air circulation system to maintain indoor air quality and prevent powder accumulation.
6. Safety performance: Choose a powder room that meets safety standards, including a reliable electrical system and emergency stop device.
7. Static control: Check whether the powder room has an effective static control device to prevent problems caused by static electricity in powder coating.
8. Brand and after-sales service: Choose a backpack powder room from a well-known brand, and consider the manufacturer's after-sales service and warranty policy.
9. Energy consumption: Consider the energy consumption of the powder room, and choose an energy-saving design to reduce operating costs.
10. Adaptability and scalability: Ensure that the powder room can adapt to future changes in production needs and has a certain degree of scalability.
