Abstract
The present invention relates to a metering-mixing device of additive for preparing high-speed railway (highway) construction special-purpose mortar and its method. Said device includes an additive container, a weighing sensor is set cover the additive container or under said additive container, said additive container is connected with additive injection pipeline by means of two parallel pipelines, on every parallel pipeline a control value is respectively set, in which on one pipeline a regulation valve is set.
Description
Technical field
The invention belongs to the system of the mixing technology of high speed iron (public affairs) road mortar, be specifically related to the device and method that the additive of system high speed iron (public affairs) road mortar is mixed in metering.
Background technology
In high-speed railway or the highway build process, must mix the asphalt cement mortar (also claiming CA mortar or BZM mortar) of a kind of special use of system, and the effect of the additive in the mortar is extremely important and be essential, therefore the metering of low dose of additive with weigh extremely important, very crucial.Volume metering way, the easy temperature influence of this volume metering method, and poor seismic behavior are adopted in the interpolation of the low dose of additive of external mortar vehicle.And, for the additive adding set that is installed on the self-propelled asphalt cement mortar cart, add only from top toward mortar under the low dose of additive situation, will cause overproof even valve closing splashes into one again with rear valve body to this section pipeline raffinate of container entrance.So low dose of precision can't reliable guarantee.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of metering to mix the device and method of the additive of system high speed iron (public affairs) road mortar.The metering of this metering additive and Weighing method, be different from volume metering method, overcome the defect of volume metering method temperature influence, solved poor seismic behavior, solved low dose of additive and added the low and precision of precision and do not reach the problem of requirement by special metering device.
Realize that the technical scheme that the object of the invention adopts is: the inventive system comprises the additive container, add agent container above or below LOAD CELLS is set, the additive container joins by two parallel pipelines and the additive flow in pipes that is provided with delivery pump, be equipped with control valve on the parallel pipeline, wherein a pipeline is provided with control valve.
Metering method of the present invention is: open the control valve of not establishing in the parallel pipeline on the control valve pipeline earlier or open control valve on the parallel pipeline simultaneously, inject additive (promptly thick title) to adding agent container; When additive is injected into the accurate measurement scope, close the control valve of not establishing on the control valve pipeline; Inject container by control valve control additive a small amount of pipeline, finish the accurate weighing of low dose of additive.
Another kind of metering method of the present invention is: open the valve on the parallel pipeline, utilize the earlier big flow of Frequency Converter Control delivery pump to inject additive (promptly thick the title) to adding agent container; When additive was injected into the accurate measurement scope, low discharge injected container again, finishes the accurate weighing of low dose of additive.
The present invention adopts, and thick, smart two stages are injected the device and the metering method of additive, the addition of the low dose of additive of accurate measurement fast, and temperature influence not, and anti-seismic performance is good, can satisfy the construct requirement of dedicated mortar of high speed iron (public affairs) road.
Further specify technical scheme of the present invention below in conjunction with accompanying drawing.
Description of drawings
Accompanying drawing is the structural representation of apparatus of the present invention.
The specific embodiment:
See accompanying drawing, apparatus of the present invention comprise additive container 1, add agent container 1 above LOAD CELLS 2 is set, additive container 1 joins by two parallel pipelines and additive flow in pipes, be respectively equipped with control valve 3,4 on the parallel pipeline, wherein a pipeline is provided with control valve 5, and the additive flow in pipes is provided with delivery pump 6.
The metering method of apparatus of the present invention: inject additive from the bottom of additive container 1 and top by thick, smart title mode (or adopt frequency control to the motor of pump).The earlier stage (being the thick title stage) that additive injects is opened the control valve of not establishing on the control valve pipeline 3 earlier, is carried the additive of coming to inject additive container 1 along pipeline by control valve 3 by delivery pump 6; When additive is injected into the accurate measurement scope, by the valve switching controls, closed control valve 3, open control valve 5 and control valve 4 on another pipeline, allow the additive of accurate measurement amount inject in the additive container 1 by control valve 5, by-pass valve control 4 along pipeline, by the Flow-rate adjustment of control valve 5, the essence of finishing low dose of additive claims.
Another kind of metering method of the present invention is: open the valve 3,4,5 on the parallel pipeline, utilize Frequency Converter Control delivery pump 6 earlier big flows to inject additive (promptly thick the title) to adding agent container 1; When additive was injected into the accurate measurement scope, low discharge injected container 1 again, finishes the accurate weighing of low dose of additive.
