Description
Technical Field
The utility model relates to a powder bin body, in particular to a blanking device for the powder bin body.
Background
The temperature difference exists between the inside and the outside of a bin of normal pressure or negative pressure powder class, or the phenomenon that the bin body is poor in sealing exists, condensed water is extremely easy to form in the bin body, the powder is compacted and hardened at the bottom of the bin body after absorbing the water, and the blanking is not smooth or the blanking opening is blocked frequently.
As shown in fig. 1, some existing powder bin bodies are usually provided with an electric tracing 1 or a vibrator 2, or both are provided with the same bin body, and the bin bodies provided with the electric tracing 1 and the vibrator 2 are common. But the material cost is higher, the installation and maintenance cost is high, the operation cost is also high, and according to the size of the bin body, the cost for adding the electric tracing and vibrator to a single discharging cone is generally 10-20 tens of thousands, and the problems can not be completely solved, and the conditions of unsmooth blanking and blanking blockage are more frequent.
The powder in the bin body is loaded and unloaded into the truck 5 by self weight through the feeder 3 and the expansion joint 4 from the pipeline. The cone hopper at the bottom of the bin body is extremely easy to cause hardening or bridging after being wetted due to the gradually smaller drift diameter. The electric tracing 1 is added outside the bin body to prevent the powder in the bin body from being wetted; the vibrator 2 is additionally arranged at the outer part of the bin body to prevent the powder in the bin body from hardening or bridging. Both methods do not directly act on powder in the bin body, have limited effects, and cannot completely solve the problems. In addition, a plurality of bin bodies are connected with one another, the vibration of the vibrator can cause the bin bodies to resonate, and once a certain bin is blanked, the powder in the rest bins which are not blanked can be compacted, hardened and bridged.
In summary, the powder bin body is provided with the electric tracing and vibrator, so that the equipment material cost is high, the installation and maintenance cost is high, and the operation cost is high. If the vibrator is additionally arranged, risks such as poor sealing, leakage and the like are easily caused at the joint of the bin body and the vibrator flange. And a plurality of bin bodies are connected with one another, the vibration of the vibrator can cause the bin bodies to resonate, and once a certain bin is used for discharging, powder in the rest bins can be compacted, hardened and bridged, so that the stability of discharging is not affected little.

fig. 2 is a schematic structural view of the blanking device of the present utility model.
Detailed Description
In order to better understand the above technical solution of the present utility model, the technical solution of the present utility model is further described below with reference to the accompanying drawings and examples.
Referring to fig. 2, the blanking device for the powder bin provided by the utility model is arranged on a blanking pipeline 11 between the bottom of the bin 10 and a feeder and comprises a main air inlet pipe 12 and a ring pipe 13.
One end of the main air inlet pipe 12 is communicated with an air source, and the other end is communicated with the annular pipe 13.
The ring canal 13 is installed inside blanking pipe 11, along the circumferencial direction of blanking pipe 11 around setting.
A plurality of vertical ventilation pipes 14 are uniformly distributed on the ring pipe 13.
Each of the ventilation pipes 14 is provided with an air jet 15, and the jet direction of the air jet 15 is aligned with the diagonally opposite inner side surface of the feed opening of the bin body 10.
The main intake pipe 12 is provided with a main valve 16, a pressure regulating valve 17 and a steam-water separator 18 in this order along the gas flow direction.
The main valve 16 is a mechanical valve.
Each of the ventilation pipes 14 is provided with a manual valve 19, and the manual valve 19 is positioned outside the blanking pipe 11.
The powder in the inner bottom of the bin body 10 is continuously back-blown through the number and the opening of the manual valves 19, so that the powder is uniformly discharged, a good inhibition effect on the caking condition is achieved, the discharging is uniform, and the blockage is not easy to occur.
The choice of the compressed gas is determined according to the medium in the bin, and inert gas such as nitrogen is preferably adopted when organic media such as inflammable and explosive media have requirements on oxygen content. The non-inflammable and explosive inorganic medium has no requirement on oxygen content and may be compressed air.
Wherein a steam-water separator 18 is used to ensure the dryness of the compressed gas blown in. The effect of air-vent valve 17 can nimble regulation compressed gas pressure, makes the powder of bin body 10 bottom constantly turn over during blanking, and the too big easy blowing of pressure is worn, and the too little powder of bin body 10 bottom of pressure also is unfavorable for turning over, adjusts gas pressure according to factors such as bin body 10 size, storehouse medium, and pressure is according to the material proportion, and back blowing pressure only needs to satisfy the material smooth and easy flow can, but can not let the material turn over too much, causes the dust volume too high in the storehouse. The main valve 16 is used to control the opening and closing of the compressed gas during blanking and stopping, as indicated by the arrows in fig. 2.
The blanking device directly adopts the pneumatic back blowing blanking device, does not damage the structure of the bin body, and has the characteristics of low cost, strong practicability, good effect, no operation cost, suitability for various powder bin bodies and the like.
The blanking device has low material manufacturing cost and operation cost, is convenient to install and maintain, and is suitable for powder bin bodies with various different mediums. After the blanking device is additionally arranged, the safety operation risk, the environmental adverse effect, the personnel labor force and the economic loss caused by overhauling after blanking is not smooth are greatly reduced.
It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the utility model, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the utility model as long as they fall within the true spirit of the utility model.
