The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
The technical scheme of the utility model practical implementation is:
Shown in Fig. 1-8; The utility model is that the aggregate that has that is used for continuous bituminous concrete mixing equipment is presorted the aggregate batching metering device that level is handled, and comprises cold aggregate material loading, and belt feeder 2 struggles against on bucket 1 and the cold aggregate; 4 cold aggregate bins 4 and 4 ingredients belts 9 thereof, gather materials; Belt conveyer 10 and frame 12 have vibratory sieve 3 and flash groove 11 above cold aggregate bin 4,4 of vibratory sieve 3 and cold aggregate bins have aggregate bin demarcation strip 6.Cold aggregate was wanted to presort level through screening machine earlier before carrying out continuous metering.Its aggregate is presorted grade treatment process can use a multi-deck screen extension set (such as 3 layers half or 4 layer); Also can be used by the screening machine of several 1 layer or 2 layers; The aggregate prescreening is become 4 kinds of (or more than 4 kinds) particle diameter grades, and it is for use to be respectively charged into 4 (or more than 4) aggregate bins.Shown in Fig. 1-8; Aggregate whether (no matter classification) is loaded onto cold aggregate elevating hopper 1, through cold aggregate charging belt machine 2, delivers on the vibratory sieve 3 that four layers of (or three and half) screen cloth are arranged; Obtain the aggregate of four kinds of specifications after the screening; By minute storehouse dividing plate 6 aggregate is stored into respectively in four aggregate bins 4, the aggregate of super-size is abandoned useless from flash groove 11, presorts the level processing thereby accomplished aggregate.
The continous batching metering of cold aggregate has three kinds of modes: (a) every kind of cold aggregate is used the volumetric method continuous metering, makes the gross weight flow of aggregate claim to carry out the gravimetric method continuous metering with belt; (b) various cold aggregates claim to carry out the gravimetric method continuous metering with belt alone; (c) various cold aggregates claim to carry out the gravimetric method continuous metering with decrement method hopper alone.
Shown in Fig. 1-2, when aggregate continous batching metering method adopts volumetric method, a belt electronic scale 15 is housed at the discharge end of the belt conveyer 10 that gathers materials.The cold aggregate of 4 kinds of specifications is prepared burden earlier with volumetric method, concentrates to deliver on the belt conveyor 10 again to be detected by the total flow of a belt electronic scale 15 with aggregate, carries out the foundation of proportion control during as later pitch metering and breeze metering.When beginning to measure, start the ingredients belt 9 of corresponding aggregate bin, the aggregate in this storehouse flows out in the storehouse; Adjust bin gate and proportioning belt linear velocity; " volume " flow velocity that guarantees the aggregate stream of outflow meets the requirements, and various aggregates are wandered on the belt conveyer 10 that gathers materials after the volumetric method batching; " in time detect the gross weight flow of several kinds of aggregate streams, the belt conveyer 10 that gathers materials has been delivered to dram through the aggregate of continous batching and total flow detection with four kinds to the belt electronic scale.Its batching flow process is: aggregate is presorted level and is handled more than one cold aggregate batching storehouse one cold aggregate continuous metering (total amount to aggregate is measured).And the batching flow process of existing continuous bituminous concrete mixing equipment is: many cold aggregate batching storehouse one cold aggregate continuous meterings (total amount to aggregate is measured); Its cold aggregate batching requires the prior classification of aggregate good; Otherwise each aggregate batching bin is if the specification of the aggregate of self adorning mixes; No matter how accurate separately metering is, and the grating of gathering materials that the aggregate bin that is mixed by 4 kinds of specifications is prepared can not reach predefined requirement certainly.The limitation place of the continous batching metering process flow process of the cold aggregate of Here it is traditional continuous asphalt mixing plant.
Shown in Fig. 3-4, when employing decrement method hopper is claimed to carry out the continous batching metering of the cold aggregate of gravimetric method, between each cold aggregate bin sluice gate 7 and its ingredients belt 9, be equipped with continuous metering bucket scale 5 and LOAD CELLS 8 thereof respectively.When beginning to measure, open the sluice gate 7 of corresponding aggregate bin, the aggregate in this storehouse is filled continuous metering bucket scale 5 fast, starts the ingredients belt 9 below the weighing hopper, and aggregate flows out from weighing hopper, falls on the belt feeder 10 that gathers materials.Each weighing hopper is by three or four LOAD CELLSs 8 supports; In time detect the gross weight of hopper; Along with ingredients belt 9 is seen aggregate off from weighing hopper; The weight of weighing hopper will reduce gradually, and through the speed that robot control system(RCS) is regulated ingredients belt 9, the accuracy that assurance batching speed can satisfy the continuous flow of this kind aggregate reaches requirement.When the aggregate of continuous metering bucket scale 5 arrives material level, once more the sluice gate 7 of aggregate bin 4 is opened to the weighing hopper charging, so go round and begin again.Every kind of aggregate all has so independently continuous aggregate metering system, and the belt feeder 10 that gathers materials has been delivered to dram through the aggregate of continuous metering with four kinds.This scheme is that various aggregates are carried out consecutive weighings separately, that is each aggregate all is through than " volumetric method " more accurate " gravimetric method " (decrement method electronic scale or belt electronic scale) continuous metering, thereby makes the grating of aggregate meet the requirements more.
As a kind of special case, for using natural sand to make the occasion of fine aggregate,, can influence the screening efficiency of reciprocating sieve, and the particle diameter of natural sand is very good, must not sieve just again and can prepare burden owing to when the water content of natural sand is higher.For adapting to this situation, a kind of design of the utility model is the natural sand that particle diameter is the good sand batch hopper of directly packing into separately, does not sieve in advance and must not pass through vibratory sieve.As shown in Figure 5, for volumetric method, the utility model is equipped with a natural sand batch hopper 14 and ingredients belt thereof, and is as shown in Figure 7, and for gravimetric method, the utility model is equipped with the natural sand weighing hopper scale 13 and the ingredients belt thereof that comprise LOAD CELLS.Shown in Fig. 5-8, and coarse aggregate (no matter classification is whether>be loaded onto aggregate elevating hopper 1, through aggregate charging belt machine 2; Deliver to a vibratory sieve that four layers of (or three and half) screen cloth are arranged: on 3; Obtain the aggregate of four kinds of specifications after the screening, by minute storehouse dividing plate 6 aggregate is stored into respectively in four aggregate bins 4, the aggregate of super-size is abandoned useless from flash groove 11; And as the natural sand of fine aggregate; Then directly install among natural sand weighing hopper scale 13 or the natural sand batch hopper 14,, must just can not prepare burden through screening because the particle diameter of natural sand is very good.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
