Abstract
The utility model relates to a powder material storing system. The powder material storing system comprises a powder material tank, wherein the powder material tank comprises a silo, a feeding pipe and a dust collecting machine, a powder material storing cavity is formed in the silo and communicated with the feeding pipe, and the dust collecting machine is installed between the powder material storing cavity and the outside; at least one buffering box is arranged on the silo and provided with an inlet and an outlet, the inlet is communicated with the upper portion of the powder material storing cavity, and the outlet is communicated with the lower portion of the powder material storing cavity through a buffering pipeline. The at least one buffering box is arranged on the silo of the powder material tank, in this way, when powder material is conveyed to the silo through the feeding pipe, air pressure in the silo can be reduced due to the function of the buffering box, and the requirement for dust collection can be met fully without improving the filtering capacity of the dust collecting machine, so that it is avoided that a safety valve is opened due to too large pressure, and the phenomenon of giving off dust is avoided.
Description
Technical field
The utility model belongs to vehicle for construction technical field, is specifically related to a kind of 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 the stirring system and the aggregate-storing system that are used in conjunction with conventionally, aggregate-storing system generally includes by multiple powder material tanks and forms powder memory system, to store the powder state materials such as 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 filter the air with powder, 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 higher than set response pressure time, safety valve is opened, and makes air in powder storage chamber or the discharge of powder state mixtures of materials, avoids powder storage cavity pressure excessive.
When annotating powder state material in powder storage chamber, conventionally make the conveying pipeline of powder transport vehicle and the feed pipe of powder material tank be communicated with, 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.Enter behind powder storage chamber, dust collecter filters 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, makes the pressure in powder storage chamber be 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 powder state material is less in powder transport vehicle), 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 build the pressure to powder transport vehicle (in industry, being called " breathing ") conventionally; close the transfer valve of powder waggon; stop exporting powder-gas mixture; and powder waggon is pressurizeed; until the pressure in 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 requiring 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 point); When serious, when the pressure in powder storage chamber is excessive, also may cause 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, cannot 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 cannot avoiding building the pressure, also has 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).
Utility model content
The purpose of this utility model is to solve the problems of the technologies described above and a kind of powder memory system is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of powder memory system, comprises powder material tank, and described powder material tank comprises silo, feed pipe and dust collecter; Described silo forms powder storage chamber, and described feed pipe communicates with powder storage chamber, and described dust collecter is arranged between powder storage chamber and the external world; Described silo is provided with at least one baffle-box, and described baffle-box has entrance and outlet, and described entrance communicates with the top in described powder storage chamber, and described outlet communicates with the bottom in described powder storage chamber by buffering pipe.
One upper lateral part of described baffle-box has the air flow guide surface of arc.
On described feed pipe, be provided with charging one-way control valve.
The utility model by being provided with at least one baffle-box on the silo of powder material tank, described baffle-box has entrance and outlet, described entrance communicates with the top in described powder storage chamber, described outlet communicates with the bottom in described powder storage chamber by buffering pipe, like this, when by described feed pipe when carrying powder in silo, due to described baffle-box effect, air pressure in silo is slowed down, the filter efficiency of dust collecter does not need to improve again, also be enough to meet the needs that gather dust, thereby safety valve also can not opened too greatly because of pressure, thereby avoid having occurred " emitting ash " phenomenon.
