Description
Technical field
The utility model relates to powder state material memory technology, and particularly a kind of powder memory system, also relate to a kind of mixing plant that comprises this powder memory system.
Background technology
Current, generally adopt the powder state materials such as powder material tank storage cement, fly ash, breeze.As mixing plant arranges stirring system and the aggregate-storing system be used in conjunction with usually, aggregate-storing system generally includes by a plurality of powder material tanks and forms the powder memory system, with powder state materials such as storage cement.
Powder material tank generally comprises silo, feed pipe, dust collecter and safety valve.Silo forms the powder storage chamber of storage powder state material.Feed pipe communicates with powder storage chamber; Dust collecter is arranged between powder storage chamber and the external world, can the air with powder be filtered, and be collected in air and suspend or floating powder state material, and by Bas Discharged.Safety valve is arranged between powder storage chamber and the external world; Pressure in powder storage chamber is during higher than the response pressure set, and safety valve is opened, and air or powder state mixtures of materials in powder storage chamber are discharged, and avoids powder to store cavity pressure excessive.
When filling powder state material in powder storage chamber, usually make the conveying pipeline of powder transport vehicle be communicated with the feed pipe of powder material tank, by Pneumatic conveyer, make powder state material and pressurized air be mixed to form powder-gas mixture again, and powder-gas mixture is flowed in powder storage chamber by feed pipe.After entering powder storage chamber, dust collecter is filtered powder-gas mixture, and most air is discharged to the external world by dust collecter, and powder state material is deposited in powder storage chamber.
The situation of filling powder state material comprises following two kinds:
Under normal conditions (as the incipient stage at filling powder state material), the powder state material large percentage in powder-gas mixture, AIR Proportional are less.Now, to the filter efficiency of dust collecter, require lower.Dust collecter can be in time by the Bas Discharged in powder-gas mixture, and the pressure that makes powder store chamber is less than the response pressure of safety valve; And then can make safety valve keep closing, avoid powder state material to leak.
Under the situation that builds the pressure (as the final stage at filling powder state material, when in powder transport vehicle, powder state material is less), the powder state material ratio in powder-gas mixture is less, AIR Proportional is when larger.In order to obtain enough delivery pressures; operating personal can be built the pressure to powder transport vehicle (being called " breathing " in industry) usually; close the transfer valve of powder waggon; stop exporting powder-gas mixture; and the powder waggon is pressurizeed; until the pressure in the powder waggon is while reaching a high value, then reopen transfer valve filling powder state material.In the moment that reopens transfer valve, in the powder-gas mixture of filling, major part is air, and powder state material accounts for a few part; Now, requiring dust collecter to have very high filter efficiency (filter efficiency now required is tens times of filter efficiency under normal conditions) could be in time by the Bas Discharged in powder-gas mixture.When the filter efficiency deficiency of dust collecter, the pressure in powder storage chamber will be at the instantaneous response pressure higher than safety valve, safety valve will be opened, and powder-gas mixture leaks by safety valve, and then produces " emitting ash " phenomenon (" emitting ash " phenomenon generally will maintain clock more than 1 minute); When serious, when the pressure in powder storage chamber is excessive, also may cause the powder material tank top to be torn or to raise, cause immeasurable loss, there is very large potential safety hazard.
Because above-mentioned two kinds of situations require to differ greatly to the filter efficiency of dust collecter, if do not produce " emitting ash " phenomenon in the situation that builds the pressure when " breathing " (), just require dust collecter to there is very high filter efficiency; But the very high dust collecter of configurating filtered ability not only cost and energy consumption increases, and key is under normal conditions, can't bring into play the effect of dust collecter, cause the huge waste (similar bombard greatly mosquito) of equipment cost and operating cost.If only meet the needs that under normal conditions, filtration is gathered dust, " emitting ash " phenomenon of the situation of just can't avoiding building the pressure, also have very large potential safety hazard.So just form an awkward situation (current mostly configuration meets the dust collecter that filters needs under normal conditions, and lets alone " emitting ash " phenomenon of the situation that builds the pressure).
Therefore, " emitting ash " phenomenon under minimizing builds the pressure situation how, when improving material filling safety, reducing equipment cost and avoiding the huge waste of operating cost is the technical barrier that current those skilled in the art need to solve.
