1. the principle of equipment
The feeding station is widely used in chemical industry, food, pharmaceutical, battery and other industries for powder bag unpacking, impurity removal, and uniform feeding.It can be installed above the silo, and the under-screen material can be directly discharged into the silo. This kind of pneumatic conveying equipment is evenly fed, and the materials are transported to the bin by the pneumatic conveying equipment after unpacking and removing impurities. During the unpacking and discharging process, the dust removal fan is always running, and the surrounding area of the feeding platform will be under negative pressure. The dust generated during pouring will not overflow, which ensures the cleanliness of the production environment and the operator is protected from dust pollution. The feeding station consists of a feeding platform, a vibrating screen, a dust collector and a control cabinet.
2.Installation and commissioning
(1)Place the feeding station at the place where production is needed, and fix it with anchor bolts (provided by the customer), or it may not be fixed.
(2) Connect the compressed air to the backflush bag, and adjust the pressure of the compressed air in the bag to 0.4 ~ 0.6Mpa by adjusting the knob on the filter pressure reducing valve. The compressed air is mainly used for the pulse backflush of the filter in the dust collector. For cleaning.
(3)Connect the power supply to the control cabinet, close the main switch, the control panel is on, set the cycle time to 16, and the pulse backflush time to 05.
(4)Touch the on / off button on the control panel, the dust removal fan and the vibration fan on the vibrating screen will start at the same time. At this time, you should observe whether the rotation direction of the dust removal fan is correct. When the rotation direction is correct, there should be a large number of exhaust outlets The air is exhausted; if the air volume at the air outlet of the dust removal fan is not large, it indicates that the rotation direction of the dust removal fan is wrong, and the machine should be stopped and the wiring of the dust removal fan motor readjusted.
(5)Backflush valve 1 and backflush valve 2 will rotate the 4 filters in the pulse backflush dust collector.
3. Troubleshooting
(1) There are several reasons for dust spilling during discharging:
① The rotation direction of the dust removal fan is wrong, just adjust the wiring phase sequence of the motor.
② If the filter is used for a long time and the resistance is too large, the filter should be replaced in time.
③ The compressed air pressure is less than 0.4Mpa and the backflushing strength is not enough.The compressed air pressure should be adjusted to 0.4 ~ 0.6Mpa in time.
④ No backflush, there is a problem with the pulse valve or the control system, it should be carefully checked.
(2) There are several reasons for the powder to pile up on the screen:
① The debris on the screen is not cleaned in time, which causes the screen to be blocked and the powder cannot pass through the screen.
② Too much powder is poured into the feeding station, and it is not transported away by the pneumatic conveying equipment in time.
