The working principle of the invention is explained as follows:
The invention is applied to any equipment or accessories needing to be fed, the air in the accessories needing to be fed (such as a vacuum hopper) is connected with the loose joint buckle 9 through a pipeline, enters the cyclone hopper body 31 of the backflushing feeder for cyclone dust removal, is filtered by the filter cloth bag 323, enters the fan 6 through the fan air inlet pipe 65, enters the dust collecting cloth bag 51 through the fan air outlet pipe 66 and the dust collecting connecting pipe 543, is filtered by the dust collecting cloth bag 51, and is discharged into the air, and the actions are repeated.
In the process that the equipment continuously runs excessively, more dust is accumulated on the filter cloth bag 323, wind resistance becomes large to a certain extent, the air quantity becomes small, the air speed of the material drawing part is reduced, the material drawing speed becomes slow, and in order to prevent the situation, the automatic recoil function of the recoil device 3 starts to play a role. When the program in the control box 2 runs for a set time, the air shut-off valve is controlled by the electromagnetic control valve 38 and the PLC to be in a closed state, the ash shut-off valve assembly 35 is controlled by the electromagnetic control valve 38 and the PLC to be in an open state, at the moment, the electromagnetic control valve 38 is controlled by the PLC to be in an open state, at the moment, the air in the air tank 36 is instantaneously released by the stored high-pressure air in advance, and the air enters the cyclone hopper body 31 of the recoil feeder to act on the filter cloth bag 323, so that dust accumulated on the filter cloth bag 323 is vibrated by the high-pressure air, and the vibrated dust enters the dust collecting cloth bag 51 and the second ash receiving hopper 52 through the open ash shut-off valve assembly 35 to be stored.
The electrical fittings (such as PLC, touch screen, etc., which are not detailed Ao Shu here because of the prior art) in the control box 2 are intelligently and automatically operated by a program set in advance, so that the filter cloth bag 323 is ensured to always maintain a normal state, and normal, stable and efficient operation of the equipment is ensured. The equipment consumable has long service life and low maintenance cost, is controlled intelligently, runs stably, almost does not need to clean the filter cloth bag 323 manually, reduces the equipment failure rate, saves the use cost, and reduces the product waste caused by shutdown and the like due to equipment shortage caused by human negligence (without timely maintenance equipment), thereby improving the yield of the product.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, but rather, the equivalent structural changes made by the description and drawings of the present invention or the direct/indirect application in other related/similar technical fields are included in the scope of the present invention.
