Description

A kind of glauber salt Finished Product Transport System

Technical field

The present invention relates to a kind of feedway of powder-product.

Background technology

In prior art, the method that usually adopts for the conveying of finished product nitre is: dry cooled finished product nitre is delivered to the finished product warehouse through the band conveyor trestle, then the packing warehouse-in.Be specially: nitre is through centrifuge dewatering, and by pneumatic conveying drying, dried nitre is stored in dried nitre storehouse; Be stored in nitre in dried nitre storehouse by the band conveyor trestle, be sent to the finished product nitre warehouse in finished product packing workshop by pumper; After dried nitre is sent to the finished product warehouse, by delivery machine discharge packing warehouse-in.Wherein, belt conveyer is a kind of friction-driven machinery of transported material in a continuous manner.Mainly formed by frame, belt conveyor, belt/roller, tightening device, driving device etc.It can with material on certain travel line, put the conveying flow process that forms a kind of material between final emptying point from initial feed.

Although it is large to adopt the band conveyor trestle to have fed distance, and very large advantage is arranged in the production technology for remote horizontal feed, there are numerous shortcomings in the wider advantage of suitable application area of Belt Conveying trestle conveying simultaneously for the conveying of finished product nitre:

1, adopt the band conveyor trestle to carry finished product nitre, occupation area of equipment is large, and equipment cost is higher;

2, the belt in the band conveyor trestle is easy to wear aging in operation, and the easy sideslip of belt, belt/roller are tied nitre dirt 3, rear rotating effect is bad, and effect is carried in impact, has improved accident rate, and maintenance cost is higher;

4, the thin easy contaminated environment of nitre dust in the transport process of dry nitre, easily cause the wasting of resources simultaneously;

5, adopt the band conveyor trestle to carry finished product nitre, the regulation and control of its operational throughput size have certain restriction, and delivery speed also has certain restriction.

Summary of the invention

The object of the invention is to: propose a kind of stable equipment operation, production efficiency is high, and the occupation of land space is little, and thin nitre is recyclable, simple operation, the novel glauber salt Finished Product Transport System that Modulatory character is strong.

Purpose of the present invention realizes by following technical proposals:

A kind of glauber salt Finished Product Transport System, comprise the airer that connects successively, feedway, Pneumatic lift, storage nitre storehouse and bag dust collector, the glauber salt outlet of described airer is communicated to described feedway, and the glauber salt outlet of described feedway is communicated to described Pneumatic lift, the glauber salt outlet of described Pneumatic lift is communicated to described storage bin, and described storage bin is provided with gas vent and is communicated to described bag dust collector.

As optimal way, described airer is fluid bed.

In such scheme, fluid bed is in order to dry finished product nitre, and after being convenient to, the strength of Pneumatic lift is carried.

As optimal way, described feedway is conveyor screw.

In such scheme, conveyor screw is in order to send into dry finished product nitre in Pneumatic lift, and the strength of being convenient to Pneumatic lift is carried.

As optimal way, described gas vent is located at described storage bin top.

In such scheme, fall to carrying out final gas solid separation according to naturally rising of air-flow and material.

In the present invention, the effect of each part is as follows:

Air lift mud pump belongs to a kind of low-pressure air convey materials equipment (Pneumatic ash conveying pump), is applicable to continuously, and the dry powdery material is carried in vertical-lift equably, and its traffic capacity is large and hoisting depth is higher.The air lift mud pump delivery system is mainly by the pump housing, delivery duct and source of the gas three parts form, it is little that it has floor area, easy for installation, reliable, simple to operation, equipment itself is almost without wearing and tearing in operational process, during work, pump body is without pressure, therefore its top feed pipeline does not need airlock; And lift pump can also overcome the inhomogeneous feed wave phenomenon that causes of feeding equipment moment feeding.

Adopt Pneumatic lift to carry the advantage of finished product nitre:

When 1, at first adopting the Pneumatic lift conveying to overcome the conveying of band conveyor trestle, floor area is large, the shortcoming that equipment investment is large;

2, secondly, Pneumatic lift does not have movable parts, and is non-maintaining, and capacity and flow are reconciled by the pressure demodulator, made up the band conveyor trestle easily aging in producing, easily the defective such as sideslip;

3, in Pneumatic lift conveying finished product nitre process, source of the gas provides the power material directly to transmit in delivery pipe, and thin nitre can be recycled by bag dust collector, has also avoided thin nitre dust polluting environment simultaneously;

4, adopt Pneumatic lift to carry, can pass through adjusting air valve in actual production process, freely control size, speed and the height of mass transport amount;

5, to have fed distance far away for Pneumatic lift, and delivery head is large, in the advantage with band conveyor trestle, has also overcome the former cost of investment and the high defective of maintenance cost, and is more economical, more practical.

Workflow of the present invention:

After finished product nitre drying device drying, be delivered to Pneumatic lift through feedway, carry, be promoted to storage nitre storehouse by Pneumatic lift, packing warehouse-in after in storage bin, finished product nitre powder falls to depositing, the gas of Pneumatic lift generation simultaneously carries the thinner finished product nitre dust of part and enters bag dust collector by gas vent, by the filtration of bag dust collector, thin nitre is recycled, and the gas after filtration enters atmosphere.

Beneficial effect of the present invention:

1, the equipment operation is more stable, and the et out of order probability is low, is conducive to the raising of production efficiency, has reduced the maintenance cost of production facilities;

2, saved the occupation of land space of plant area;

3, not only reclaim the waste of having avoided resource of thin nitre, and protected environment;

4, in production, transport efficiency is high, stable, and it is more convenient to operate;

5, Modulatory character is strong, can control according to actual conditions the operational throughput of finished product nitre in process of production.
