The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the utility model.
Referring to Fig. 3, show first preferred embodiment of a kind of sand material drying system of the utility model.As shown in the figure, this sand material drying system comprises fluidized bed furnace 1 and the knockout pipe 2 that is arranged on air outlet 10 places of fluidized bed furnace 1.Knockout pipe 2 comprises outer tube 21 and the interior pipe 23 that is arranged in the outer tube 21, and wherein, the knockout pipe installing hole on outer tube 21 and the fluidized bed furnace 1 (among the figure not label) cooperates, and interior pipe 23 forms sand materials flow circulation passage.Outer tube 21 and interior pipe 23 for example connect through the support 25 that is arranged between the two, between outer tube 21 and interior pipe 23, form heat insulation path 20.Heat insulation path 20 is similar to the annular chamber of a hollow, and this annular chamber can be an annular seal space, also can be equal opening in two ends or the cavity that has only an end opening.Under the effect of this heat insulation path 20; The temperature of pipe 23 is unlikely to too high in can guaranteeing; Damp sand to be dried can get into after interior pipe 23 falls smoothly and follow the supporting drying plant of fluidized bed furnace, and pipe 23 inwalls in sticking to after being not easy to be sintered, thereby avoided knockout pipe 2 blocking problem; Therefore do not need the workman often to clear up yet, reached the effect of carrying out smoothly, enhancing productivity of alleviating working strength of workers, guaranteeing production.Preferably, the upper end of interior pipe 23 is infundibulate, and it is effective to lead sand.
For internally pipe 23 is heat insulation better, by it can also be seen that among Fig. 3, preferably, the end, upper end of heat insulation path 20 is a blind end, and the end, lower end is openend (for example can the upper end of outer tube 21 and interior pipe 23 be welded together, the lower end is not connected); Offer porose 210 on the top of outer tube 21; Hole 210 communicates with second end of cold wind flow in pipes 6; First end of cold wind flow in pipes 6 is the cold wind inlet; For example continue to inject cold wind through air blast 7 equipment such as grade to the cold wind inlet of cold wind flow in pipes 6, the cold wind air communication is crossed cold wind flow in pipes 6 and constantly is introduced into heat insulation path 20 then from the opening discharge of heat insulation path 20 lower ends, is equivalent to outer tube 21 and carries out air blast cooling with interior pipe 23.Like this, on the one hand, interior pipe 23 can guarantee further that under the heat insulation and heat control effect of cold wind air-flow self temperature is unlikely to too high, avoids the damp sand sintering on inner tubal wall; On the other hand, also can reduce the high temperature injury of fluidized bed furnace 1 outer tube 21.Hole 210 is opened in the part that is positioned at fluidized bed furnace 1 top of outer tube 21 usually, so that the cold wind flow in pipes 6 of arranging.
Need to prove, be for the hot blast that the fluidized bed furnace air outlet blows out, to be cold wind at the cold wind of being mentioned in the utility model, and the cold wind wind regime can adopt natural wind usually.When the cold wind wind regime adopts natural wind, can the air outlet of air blast 7 be communicated with the air intake vent 12 of fluidized bed furnace 1 and the cold wind inlet of cold wind flow in pipes 6 respectively, to optimize structure.In addition; In the present embodiment, outer tube 21 is an example to be installed in the knockout pipe installing hole on the fluidized bed furnace 1, but in practical application; Outer tube 21 also can be arranged on the outside of fluidized bed furnace 1, and for example the outer wall of outer tube 21 passes through stent support between the air outlet 10 and drying plant of fluidized bed furnace 1.
By finding out among Fig. 3, this sand material drying system also comprises dryer 3, and dryer 3 is arranged on the air-out oral-lateral of fluidized bed furnace 1, and the sand inlet 30 of dryer 3 communicates with the air outlet 10 of fluidized bed furnace.The lower end of knockout pipe 2 is stretched in the sand inlet 30 of dryer 3, guides damp sand to be dried from the sand materials flow circulation passage that interior pipe 23 forms, to slip into the processing space of dryer 3, avoids damp sand to get into the combustion chamber of fluidized bed furnace.Dryer 3 is equipped with air inducing dust arrester 4 further away from an end of fluidized bed furnace 1; Air inducing dust arrester 4 is used for the hot blast that fluidized bed furnace air outlet 10 is discharged is introduced dryer 3 so that damp sand is heated; And with discharging dryer behind the tail gas filtering; Thereby guarantee the normal drying of damp sand, dry later sand and discharge through the discharge gate 5 of dryer 3.The air-flow of discharging from heat insulation path 20 lower ending openings in addition, is also discharged by air inducing dust arrester 4.Need to prove, less relatively because of the cold wind throughput in the heat insulation path 20, can not influence the drying effect of dryer 3.
In a kind of unshowned embodiment; It is second preferred embodiment of the utility model; Be that with the difference of above-mentioned first embodiment knockout pipe 2 does not stretch in the sand inlet of dryer 3, between the air outlet 10 of the sand inlet 30 of dryer 3 and fluidized bed furnace, be tiltedly installed with stock guide; Stock guide is positioned at the below of the lower end of knockout pipe 2, damp sand to be dried is imported in the sand inlet of dryer 3.
Need to prove; Introducing fluidized bed furnace, air blast, cold wind flow in pipes 6 etc. in the utility model only is for this device better is described; It can adopt multi-form source of the gas and communicating pipe to connect the heat insulation path between outer tube and the interior pipe (square tube, pipe etc.); This structure can be used for the drying system of different fuels such as the fire coal, combustion gas, fuel oil except that fluidized bed furnace, but all belongs within the protection domain.
In sum, the sand material drying system of the utility model has the following advantages: 1) simple in structure, cost is low.2) it is respond well to prevent that damp sand sintering in material blanking tube from stopping up.3) effectively reduce workman's working strength.
The utility model also provides a kind of dry-mixed mortar mixing plant, and in conjunction with reference to figure 3, this dry-mixed mortar mixing plant comprises: be used for promoting sand material elevator (Fig. 3 is not shown), the sand material elephant trunk 8 of treating the baked sand material, and above-mentioned sand material drying system.Sand material elephant trunk 8 is obliquely installed usually and has certain length, and the sand material output of sand material elevator is accepted in the upper end of sand material elephant trunk 8, and the lower end is corresponding to the upper end of interior pipe 23.Sand material elevator is used for treating that the baked sand material is promoted to certain altitude, will treat that through sand material elephant trunk 8 the baked sand material is delivered in the sand materials flow circulation passage of interior pipe 23 then.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
