Description
Technical field
The present invention relates to technical field prepared by dry-mixed mortar, particularly a kind of system and methods for preparing dry-mixed mortar.
Background technology
Dry-mixed mortar is the final side for one kind and green construction material development being most widely used in premixing mortar
To.As mortar for building, dry-mixed mortar plays bonding, liner, protection and decoration with thin layer in building and structures and makees
With with the promotion of modern architecture industry construction ability, dry-mixed mortar was as flexibly with the construction material of sustainable supply, both meeting
Building performance, while meet that mechanized construction is quick, and amount is big, transient demand amount increases swift and violent construction demand, in building and
Fitting-out work is using extremely wide.
Dry-mixed mortar by cementitious material, gather materials, admixture and additive mix according to a certain percentage, dry-mixed mortar
The raw material of middle most critical are additives, this is also that dry-mixed mortar is different from one of notable mark of traditional architecture mortar, wherein
Often production 1t dry-mixed mortars take around the additive using 150g~200g, that is to say, that additives for Dry-Mixed Mortar quality accounts for sand
The 0.015%~0.02% of gross mass is starched, although additives for Dry-Mixed Mortar usage amount is considerably less, but it is dry-mixed to play increase
The intensity of mortar improves the adhesive property of mortar, optimizes the initial workability of building mortar, solves part mortar durability
Difference or even effect the problems such as can not construct, additives for Dry-Mixed Mortar is to thicken based on water retention property, to improve the various property of mortar
Supplemented by energy, the development of modern mortar technology is exactly being applied to various additive economical rationality in premixing mortar, existing to meet
For the needs of Building technology development, in premixing mortar product cost, additive accounts for sizable ratio, therefore dry-mixed mortar
The slightly deviation of metering system will not only significantly affect the quality of dry-mixed mortar, while will also result in mortar production cost drastically
Increase.Quickly and accurately feedback metric results are the basic demand of metering system, at the same how to allow trace mineral supplement with it is a large amount of
Material is uniformly mixed even more metering system and the important symbol of production system perfect adaptation.
Fig. 1 is the structure diagram of traditional mode of production dry-mixed mortar device, it includes raw material storage system, material transportation system
System, facilities of mix storied building etc..Setting in facilities of mix storied building includes blender, finished bin etc., includes some temporary memory devices at the top of blender
Such as the storage tank that gathers materials, admixture storage tank, cementitious material storage tank and additive storage tank etc., material is facilitated to fall directly into blender.
Above-mentioned temporary memory device discharge port connects, and lower part is provided with metering device with blender.Prepare the work of dry-mixed mortar
Skill is：To weigh respectively accurately gather materials, the materials such as admixture, cementitious material are transported by screw conveyor to bucket lifting
Machine enters by bucket elevator in interim storage tank, then opens the additive valve in additive storage tank, passes through helical feed
Additive is transported to metering device by machine, and additive is fallen on weighing sensor, shows weight amount, when outer needed for arrival
When adding the weight of agent, stop feed, then the additive weighed up is sent into blender, then passes through the agitating shaft in blender
Drive stirring blade rotation so that gather materials, cementitious material, admixture and additive uniformly mix, finally by be uniformly mixed
Finished product is sent into product storehouse.
There are following defects for above-mentioned dry-mixed mortar measuring equipment：（1）Often production 1t dry-mixed mortars are taken around using 150g
The additive of~200g, additive usage amount is extremely small, is stirred the uneven fluctuation that can lead to product quality, influences sand
Slurry uses and performance.To ensure mixed effect again, it usually needs extend mixing time, this is undoubtedly increased to agitating shaft and stirring
The wear damage of leaf, shortens the service life of blender, while also reduces production efficiency.（2）Weighing sensor metering is outer
During adding agent, due to generating larger vibrations when blender works, facilities of mix storied building is caused to be in apparent and swings environment, sensitivity
Weighing sensor by the severe jamming of ambient enviroment, sensor can not differentiate load or material from ambient enviroment
The load of whereabouts, so as to ensure the accuracy of the metric results of weighing balance.（3）Cementitious material, admixture and gather materials directly
It leaks into blender, material causes going out for gas in the confined space, most probably influences the accuracy of measuring equipment, also reduces
The service life of measuring equipment.Therefore, the measuring equipment of existing dry-mixed mortar is difficult to meet the needs of mortar production.
