Further, described grain slag loading groove has some groups, and annular close arrangement between each group grain slag loading groove, described distributor is revolving top.
Further, described dewatering unit and blow-off valve have some groups, and correspondence is arranged on below each group of grain slag loading groove.
Further, the dolly that catchments is provided with below described blow-off valve.
Further, described handling equipment is conveyor drive.
The present invention also provides a kind of and is applicable to the storage process that above-mentioned grain slag cloth stores production line, mainly comprises the following steps:
1) utilize handling equipment grain slag to be delivered to from afar hopper place to collect;
2) grain slag be collected in hopper is stored in grain slag loading groove by distributor;
3) the grain slag loading groove of having bought securities with all one's capital stores grain slag for some time, and realize the separation of water, isolated water is discharged by dewatering unit;
4) grain slag through storing dehydration is discharged by blow-off valve, waits for that the grain slag of discharge is transported by the slag waggon below blow-off valve.
Further, when grain slag loading groove has some groups, adopt revolving top; Send to Controlling System signal of buying securities with all one's capital when the grain slag in a grain slag loading groove is bought securities with all one's capital, Controlling System controls revolving top and rotates above the grain slag loading groove of other skies, revolving top continue to cloth in new grain slag loading groove, repeating step 2), 3) and 4).
Further, the water leaked out from dewatering unit and blow-off valve collected by the dolly that catchments be arranged on below blow-off valve.
Further, step 4) in before slag waggon receives grain slag, the Controlling System dolly that first controls to catchment is removed, then opens blow-off valve discharge, and after the grain slag in grain slag loading groove is emptying, the Controlling System dolly that controls to catchment is got back to and collected position, closes blow-off valve.
Further, from grain slag isolated water through recovery system recycling.
Beneficial effect of the present invention is: production-line arrangement is flexible, and floor space is little, compact construction, without the need to extra colonnade, effectively reduces cost and drops into; Entire system dehydrating effect is good, can be realized the discharge of grain slag water by the dewatering unit of grain slag loading groove bottom, and the dolly that catchments can collect unexpected water, can effectively avoid grain slag water to be scattering on ground; The recyclable recycling of grain slag water collected, avoids the wasting of resources, environmentally friendly; Employing automation control system controls, and saved human cost, reliability is high.
Accompanying drawing explanation
In order to make object of the present invention, technical scheme and beneficial effect clearly, the invention provides following accompanying drawing and being described:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the sectional drawing of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in the figure, grain slag cloth in the present embodiment stores production line, comprise the hopper 2, distributor 3, grain slag loading groove 4 and the blow-off valve 6 that are corresponding in turn to layout from top to bottom, also comprise handling equipment 1 and dewatering unit 5, described handling equipment 1 connects with hopper 2, be taper bottom described grain slag loading groove 4, described dewatering unit 5 is connected with bottom grain slag loading groove 4.Each equipment is vertically arranged, effectively can reduce the floor space of production line, make overall system architecture compact, reduce cost investment.
As the further improvement of such scheme, described grain slag loading groove 4 has some groups, and annular close arrangement between each group grain slag loading groove 4, described distributor 3 is revolving top.Grain slag loading groove 4 in the present embodiment has four groups and is arranged to matrix pattern, and revolving top can successively to cloth in each group of grain slag loading groove 4, to improve its operating efficiency.
As the further improvement of such scheme, described dewatering unit 5 has some groups with blow-off valve 6, and correspondence is arranged on below each group of grain slag loading groove 4, the dehydration of different group grain slag, discharge and shipment can be realized, manipulate respectively, its reliability can be improved, can operating efficiency be improved again.
As the further improvement of such scheme, be provided with the dolly 7 that catchments below described blow-off valve 6, the water that blow-off valve 6 can leak out by the dolly 7 that catchments is collected, and avoids being scattering into ground pollution environment.
Handling equipment 1 in the present embodiment is conveyor drive, certainly, also can select the transfer roller of other types.
The present invention also provides a kind of and is applicable to the storage process that above-mentioned grain slag cloth stores production line, mainly comprises the following steps:
