Mobile Dust Removal Equipment

Dust collector and dust hood positioning (dimensions in the figure are in mm)

Dust collector power input:

The power input is 380V, 50HZ, and the equipment should be well grounded.

Dust collector compressed air input:

The compressed air input is between 0.5-0.8Mpa. The compressed air must be filtered through a dryer or air filter for oil-water separation before it can be connected to the dust collector air tank.

Control panel introduction:

The dust removal equipment should be operated by a person who is familiar with the performance and the basic principles of the control system.

1. When the power is on, press the "Start" button to blow air 01 to enter the pulse cleaning. The system digital display light shows that it will enter the next pulse cleaning cycle. Press the "Start" button to start the dust collector fan.

2. Press the "Stop" button when shutting down. If the dust collection efficiency feels poor, you can press the "Clean" button again. At this time, the fan will not start and enter the offline pulse cleaning cycle mode. After the system setting cycle is cleaned, the offline cleaning cycle mode will automatically stop.

3. Set pulse parameters: Press ‘Cycle Time’ for a short time to adjust the online cleaning cycle time of the “Startup” program segment (i.e., when the fan is running, the pulse automatically cycles to clean the dust). The parameter is generally set to 60-500 seconds. “△▽” is for digital size adjustment, and “▷▷” is for movement adjustment from the unit to the thousandth place. After setting, press “OK” to save; press ‘Cycle Time’ for 5 seconds for the pulse cleaning cycle time of the “Offline” program segment. The parameter is generally set to 10 seconds. After setting, press “OK” to save; press ‘>>’ for 5 seconds for the cleaning times. The parameter is set to about 160 times. After setting, press “OK” to save.

Causes and troubleshooting of faults:

1. Loud fan noise:

Causes: ① Fan reverse ② Fan bearing damage ③ Fan screws loosened ④ Fan power input phase loss

2. Poor dust collector effect:

Causes: ① Fan reverse ② Pulse backblowing not performed ③ Bag service life exceeds 2 years ④ Whether there is air leakage in the dust collector

3. Control panel does not display:

Causes: ① Power is not input or neutral line is disconnected ② Whether the switch power supply is damaged ③ The panel itself is damaged

4. Air switch trips:

Causes: ① Fan motor overload ② Power phase loss ③ Electrical accessories damaged ④ Dust suction port blocked

5. Pulse air leakage:

Causes: ① Pulse diaphragm damaged ② Pulse diaphragm is stuck with foreign matter ③ Pulse valve damaged

6. Thermal overload relay pops out:

Causes: ① Thermal overload relay amperage is adjusted too small or damaged ② Dust suction port blocked

 Maintenance and care

1. Regularly check whether compressed air enters the gas tank, and check whether the pulse valve and air pipe are leaking. The pulse valve diaphragm needs to be replaced within 2 years of its service life.

2. Regularly check whether the power line is aging and worn, and it needs to be replaced after 3-5 years.

3. Whether the dust collector is reliably grounded.

4. Regularly check whether the electrical components in the distribution box are damaged or aging, and they need to be replaced after 2-3 years.

5. Regularly check whether the dust bag is damaged, and it needs to be replaced within 2 years of its service life.

6. Every time the filter bag is fully replaced, the dust in the box should be thoroughly cleaned.

7. The pulse valve core and spring should be cleaned regularly, and the oil should be wiped off with alcohol to prevent the core and spring from being precipitated and sticking, which makes the action inflexible. If the spring is broken, it should be replaced immediately.

Bag maintenance plan and steps

In order to ensure the safe and stable operation of the equipment, the bag must be replaced every two years according to the on-site working conditions. The maintenance content is to repair or replace the bag. Be sure to wear a gas mask or mask for maintenance. The specific steps are as follows:

1. After stopping the machine, turn off the external line switch of the dust collector and remove the power cord to ensure that there is no power before maintenance.

2. Turn off the external compressed air source, open the pressure relief port at the bottom of the gas tank, and discharge the gas.

3. Remove the pulse valve coil screw and pull out the coil, and place the screw in the container to prevent loss.

4. Remove the connecting bolts between the upper box and the lower box of the dust collector, and place the screw in the container to prevent loss.

5. Lift the upper box of the dust collector and place it on the ground (there is a lifting ear around the top), and you can see the clean air layer.

6. First remove the fastening screws and slipknots of the injection pipe in the clean air layer.

7. Slowly pull up the bag dragon frame from the middle of the bag hole. Note: If you encounter resistance, you can shake the frame gently and then pull it back until the entire frame is lifted out of the clean room.

8. Pinch the clamp ring at the mouth of the bag until it is deformed, then you can pull out the bag or put the bag down to the bottom ash box.

9. The bag should be installed in the reverse order of the above. Do not turn on electricity or gas during this process.
