fig. 2 is an enlarged schematic view of the high pressure compressed air nozzle in the embodiment of fig. 1.

In the figure: 1. the device comprises an air compressor, 2, an air storage tank, 3, a filter, 4, a dryer, 5, a pneumatic electromagnetic valve, 6, an air inlet pipe, 7, a high-pressure compressed air nozzle, 8, a storage bin, 801, a main body of the storage bin, 802, a conical bottom, 9, a maintenance valve, 10 and a blanking device.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, this embodiment includes 4 high-pressure compressed air nozzles 7 that are the stepped distribution of annular in 8 lower parts of feed bin awl end 802, high-pressure compressed air nozzle 7 passes through intake pipe 6 and is connected with desiccator 4, and desiccator 4 is connected with gas holder 2, and gas holder 2 is connected with air compressor machine 4, is equipped with filter 3 between gas holder 2 and the desiccator 4. The desiccator 4 can guarantee to enter into the aridity of the high pressure compressed air of feed bin 8, can not bring new moisture for the material in the feed bin 8, and filter 3, gas holder 2 and air compressor machine 1 open at ordinary times, close when needing the maintenance.

The storage bin 8 in the embodiment is formed by welding explosive bimetal composite plate coils, or a layer of stainless steel plate is additionally welded at the conical bottom of the original single-layer storage bin.

The high-pressure compressed air nozzle 7 is vertical to the inclined side wall of the conical bottom 802, and when the high-pressure compressed air cutting machine works, high-pressure compressed air is sprayed out from the high-pressure compressed air nozzle 7 and then is intersected with the conical bottom 802 of the storage bin 8 to form air flow knives towards the discharge hole, backwards and beside, so that materials staying on the conical bottom 802 are cut and impacted; under the condition that the blanking device 10 arranged at the bottom outlet of the conical bottom 802 stops working, materials cannot be emptied from the conical bottom 802, high-pressure air enables particles of the materials to diffuse upwards to fluidize the materials, then the materials flow to a discharge port through the conical bottom of the smooth storage bin, and the materials are evenly blanked through the blanking device 10.

The air inlet pipe 6 is perpendicular to the main body 801 of the storage bin, the air inlet pipe 6 is connected to the high-pressure compressed air nozzle 7, the air inlet pipe 6 is concentrically and annularly distributed above the storage bin 8, the air inlet pipe on each ring is communicated, and the pneumatic electromagnetic valve 5 with the pressure resistance of 1.6MPa is mounted on each ring and used for controlling the high-pressure compressed air to flow into the storage bin 8 when necessary. The control mode has two options: one is that before each time of blanking, the material in the bin 8 is subjected to arch breaking and/or fluidization in advance, namely, the material in the bin 8 is fluidized regardless of whether arch is formed or not; the second is whether the material in the feed bin 8 is buckled or not is judged by detecting the flow of the blanking during the blanking, if the flow is less, the material in the feed bin 8 is buckled, at the moment, the pneumatic electromagnetic valve 5 above the feed bin 8 is controlled by the starting controller to be sequentially opened and closed, and the material in the feed bin is broken and fluidized until the material flow is normal.

Because of the material in the feed bin 8 is different to the sensitivity of moisture, adopt desiccator 4 to carry out the drying to compressed air, guarantee to the material dryness in the feed bin 8, do not produce harmful effects to its moisture content.

Various modifications and variations of the present invention may be made by those skilled in the art, and they are within the scope of the present invention provided they are within the scope of the claims and their equivalents.

What is not described in detail in the specification is prior art that is well known to those skilled in the art.
