more specifically, the negative pressure dust removal filter element 3 is fixed on the fixed support, and a dust removal filter element baffle 4 is arranged on one side of the negative pressure dust removal filter element, which is opposite to the feeding bin door, so that materials are prevented from being directly adsorbed to the filter element during feeding;
the working principle of the present invention is further described below by referring to the specific part names in fig. 1:
when the device is used, a feeding bin door (18) can be opened through a bin door handle (19) manually, an equipment starting switch is installed on the feeding bin door (18), and when the bin door is opened, the equipment runs; when the equipment runs, a fan motor (9) is started, and negative pressure is formed in the feeding bin due to the work of the dust removal fan (1); simultaneously starting a vibration motor (21); when a feeding bin door (18) is manually opened, a required material finished product bag is fed onto a material pouring platform (6), the material finished product bag is manually opened, the powder material is poured into an inner feeding bin (15), and the powder material is conveyed to a designated position through pneumatic conveying equipment of a rear vacuum conveying connecting piece (8).
In another embodiment, a back-blowing pulse valve 11 is arranged outside the negative pressure dust-removing filter element, and the back-blowing pulse valve 11 is connected with an air storage tank 12 through an air pipeline and is used for controlling a switch of back-blowing pulse;
during specific implementation, the back-blowing pulse valve (11) controlled by an external controller intermittently drives air in the air storage tank (12) into the main box body of the equipment according to set time so as to blow off dust on the dust removal filter element (4).
In another embodiment, a plurality of buffers 7 are vertically connected below the feeding bin, and are used for buffering the relative movement between the feeding bin and the bracket for fixing the feeding bin, which is caused by the vibration of the vibration motor.
More specifically, an air-supply breather valve 16 is arranged below the feeding bin;
when the utility model is implemented, the utility model can be installed and debugged through the following steps:
1. the feeding station is placed at a place where production needs, and is fixed by foundation bolts (customer self-provided) or not.
2. Compressed air is connected into a back-blowing air bag, the pressure of the compressed air in the air bag is adjusted to 0.4-minus 0.6Mpa by adjusting a knob on a filtering pressure reducing valve, and the compressed air is mainly used for pulse back-blowing and ash removal of a filter in a dust remover.
3. The power supply is connected into the control cabinet, the main switch is switched on, the control panel is on, the cycle time is set at 16, and the pulse back-blowing time is set at 05.
4. An opening/closing button on the touch control panel is touched, the dust removal fan and the vibrating fan on the vibrating screen are started simultaneously, and whether the rotating direction of the dust removal fan is correct or not is observed at the moment. When the rotation direction is correct, a large amount of air should be discharged from an air outlet of the dust removal fan; if the air quantity of the air outlet of the dust removal fan is not large, the rotation direction of the dust removal fan is wrong, the dust removal fan is stopped, and the wiring of a fan motor is readjusted.
