The specific embodiment
Shown in Fig. 1-8, the utility model is the aggregate batching metering device that the pre-classification of aggregate is handled that has that is used for continuous bituminous concrete mixing equipment, comprise cold aggregate elevating hopper 1 and cold aggregate charging belt machine 2,4 cold aggregate bins 4 and 4 ingredients belts 9 thereof, gather materials belt conveyer 10 and frame 12, vibrosieve 3 and flash groove 11 are arranged above cold aggregate bin 4, and 4 of vibrosieve 3 and cold aggregate bins have aggregate bin demarcation strip 6.Cold aggregate was wanted to carry out pre-classification by screening machine earlier before carrying out continuous metering.The pre-classification treatment process of its aggregate can be with a multideck screen extension set (such as 13 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 stand-by 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, by cold aggregate charging belt machine 2, deliver on the vibrosieve 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, handles thereby finished the pre-classification of aggregate.
The continous batching metering of cold aggregate has three kinds of modes: (a) every kind of cold aggregate volumetric method continuous metering, and the gross weight flow of cold aggregate claims 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 proportional 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, belt electronic scale 15 in time detects the gross weight flow of several aggregate streams, and 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.Its batching flow process is: more than one cold aggregate batching storehouse one cold aggregate continuous metering (total amount to aggregate is measured) is handled in the pre-classification of aggregate.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 metering separately 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 bituminous concrete mixing equipment.
As shown in Figure 3-4, when employing decrement method hopper claims 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 conveyor 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 sent aggregate from weighing hopper, the weight of weighing hopper will reduce gradually, by 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 conveyor 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,,, must not sieve again just and can prepare burden owing to when the water content of natural sand is higher, can influence the screening efficiency of reciprocating sieve, and the particle diameter of natural sand is very good for using natural sand to make the occasion of fines.For adapting to this situation, a kind of design of the present utility model is the natural sand that particle diameter is the good sand batch hopper of directly packing into separately, and must sieve in advance through vibrosieve.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 as shown in Figure 7, 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, coarse aggregate whether (no matter classification) is loaded onto aggregate elevating hopper 1, by aggregate charging belt machine 2, deliver on the vibrosieve 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, and as the natural sand of fines, then directly install among natural sand weighing hopper scale 13 or the natural sand batch hopper 14, because the particle diameter of natural sand is very good, must just can not prepare burden through screening.
