Description
Technical field
The invention belongs to inflammable and explosive industrial powders to store equipment technical field, specifically be exactly to be related to a kind of powder cabin heat tracing
Help streaming system.
Background technique
In industrial processes, the mining industry fuel such as coal is usually ground into powdery and then carries out subsequent production or benefit again
With, just need storage system temporarily to put it in transport process, current widely used storage system is vertical type cylinder shape powder cabin,
Such powder cabin exit caliber is small, and blanking is conical.In entire powder cabin, active force between powder particles with the reduction of height and
Increase, co-acting force reaches maximum between the particle of exit.Since powder particles diameter is respectively less than 0.5mm, so exporting
Big van der Waals, i.e. attraction are just also easy to produce between the particle at place.In addition outlet diameter is small, the low material of environment temperature gets damp,
Then miberal powder is easily tied arch bridging mobility and is substantially reduced, and is not easy to fall from outlet.If exclusive use helps gas pad, once cone storehouse is stifled
Plug, lower part powder bulk density increase, and stream positice ground effect is helped to substantially reduce, and user, which can only tap the methods of vibration by outside, to be made
Slow, a small amount of whereabouts of powder, the normal operation of serious influence system.In order to overcome above-mentioned powder to be difficult to smoothly flow from powder cabin
Technological deficiency out, Chinese patent 201210397765.4 disclose a kind of buffer and help stream powder cabin, are particularly used for miberal powder
It smoothly flows out.It includes cross reinforced pipe, coaming plate and helps gas pad, and cross reinforced pipe is located in warehouse, four end of cross reinforced pipe
It is welded and fixed and connect with warehouse inner wall.The coaming plate bottom is weldingly fixed on cross reinforced pipe.The storehouse of cross reinforced pipe lower part
Internal surface, which is bolted, multiple helps gas pad.This is simple, compact and reasonable for structure；It is suitable from powder cabin outlet to facilitate miberal powder
Under agile；It is low in cost；Avoid miberal powder blocking warehouse.
But the clearly only security performance on probation powder storage of less demanding of above-mentioned modified powder cabin, it is easy for coal etc.
The storage for firing explosive mineral powder is obviously not suitable for, and Chinese patent 201520443846.2 discloses a kind of pulverized coal bin, including is in
The blanking portion of taper and the storage department connecting with blanking portion, the blanking portion are equipped with heating mechanism, and the heating mechanism includes companion
The torrid zone, insulating layer and the power supply for heating tape energy supply, the heating tape uniform winding is in blanking portion, and the heating tape and power supply
Connection, the insulating layer wrap up blanking portion and heating tape simultaneously.The utility model increases heating mechanism in the outer wall of pulverized coal bin, right
Pulverized coal bin is heated, is kept the temperature, and is reduced influence of the environment to coal dust, is avoided the bulkhead in pulverized coal bin from condensing, prevent coal dust
It agglomerates, guarantees smooth lower coal.But the anti-exposure limited strength of this kind of pulverized coal bin, amount of storage is limited, can not especially supervise in real time
The situations such as pressure and temp in powder cabin are controlled, coal dust is not can avoid and agglomerates in powder cabin, what is still utilized is self gravity from powder cabin
Outflow influences unit normal operation once coal dust agglomeration will block.
Summary of the invention
The purpose of the present invention is to the technological deficiency that existing inflammable and explosive powder material storage system is easy to happen blocking,
A kind of powder cabin heat tracing is provided and helps streaming system, which can be avoided the agglomeration of the powder in powder cabin, by the improvement to feed system,
