Background technique
Currently, the Preparation equipment of cement sand and gravel material or concrete material mainly mixes and stirs production and continuous using intermittent
Formula mixes and stirs production two ways.Intermittent to mix and stir production be first respectively to weigh cement, flyash, additive and water, then will
The material of weighing inputs mix and stir in host respectively, mixes and stirs host at this time and no longer receives supplied materials and carry out Hermetical stirring, to material
After stirring reaches the stipulated time, finished product is disposably poured out；And continous way mix and stir production be by cement, flyash, additive and
The materials such as water respectively mix and stir in host incessantly by input, mixes and stirs host and receives supplied materials on one side, exports finished product material on one side, real
Now continuously feed and discharging.The characteristics of mixing and stirring host in view of above-mentioned continous way, makes it have that equipment manufacturing cost is low, operation energy consumption
Low, the advantages that occupied area is small, be easily installed and arrange, high production efficiency, therefore be widely adopted in engineering construction.
However, current continous way mixing apparatus, which generallys use powder, liquid material and aggregate, individually weighs again respectively input
The pan feeding mode in host is mixed and stirred, for example, powder mixes and stirs host, water and additive using screw(-type) feeder consecutive weighings and input
Host is mixed and stirred using flowmeter and water pump consecutive weighings and input.Existing continous way mixing apparatus is all made of above-mentioned pan feeding side
Formula, although this pan feeding mode can also produce qualified construction material, there is also some problems.
For example, cement and flyash is as dust material, there is very big fugitive dust in pan feeding and mix and stir during, cause to construct
Bad environments；In addition, cement and flyash can not sufficiently merge in the agitator for mixing and stirring host with water and aggregate, lead to aggregate
The phenomenon that white powder and cement formation powder packet, is wrapped up on surface, so that mixing and stirring unevenly, leads to the quality defect of finished product；It is given using spiral
The metering of the continuous meterings equipment such as material machine, flowmeter is inaccurate, inaccurate etc..
In order to overcome above-mentioned difficulties, stirred in engineering using the closed method reply dust problem mixed and stirred, and increase
Non-uniform problem is mixed and stirred in power and the method reply for increasing mixing time.But due to there is not closed feeding inlet, powder
Dirt problem can not be solved effectively, and by increasing the method mixed and stirred power and increase the mixing time, so that uniform mixing degree
Improve limited, while also increasing and mixing and stirring cost, reducing production efficiency.
The mode of the independent pan feeding of the raw material of the dust characteristics such as cement, flyash is the main reason for there are fugitive dusts；And water
Mud, flyash converge with water again after entering agitator, and aggregate also comes into agitator at this time, and therefore, cement, flyash are at this time
The time for needing to be mutually mixed with aggregate contention and water and space cause to mix and stir uneven.

Electric butterfly valve 37 and electric butterfly valve 29 are in the open state, and slush pump 20 and slush pump 21 are in halted state；All powders
Screw conveyor and all water pumps are also at halted state.In addition, needing to guarantee before booting to have abundance in cement bin 25
Cement has sufficient flyash in fine coal ash cellar 26, has sufficient clear water in sump 27, is to have matched in liquid additive storehouse 28
The additional agent solution set.
(2) water pump 13 being connected with sump 27 injected clear water into agitator 1, while biography of weighing ingredient: are first turned on
17 real-time monitoring mass change of sensor switches off the pump 13 after mass figures rise to 500kg by 0kg, secondly opens and liquid
The water pump 14 that additive bin 28 is connected, injects additional agent solution into agitator 1, the numerical value of sensor 17 to be weighed by
After 500kg rises to 1000kg, 14 are switched off the pump, be then turned on the powder screw conveyer 9 that is connected with cement bin 25 to stirring
Cement is inputted in bucket 1, after the numerical value of sensor 17 to be weighed rises to 1500kg by 1000kg, closes powder conveyer 9, finally
It opens the powder conveyer 10 being connected with fine coal ash cellar 26 and inputs flyash, the numerical value of sensor 17 to be weighed into agitator 1
After rising to 2000kg by 1500kg, powder screw conveyer 10 is closed.Agitator 1 completes ingredient at this time.
(3) material stirring: after agitator 1 completes ingredient, the revolving speed of stirring rod 3 and stirring blade 35 is adjusted to high-speed rotation
State, revolving speed are 60 revs/min, high-speed stirred material 2-3 minutes, are stirred until by cement and flyash.Later
The revolving speed of stirring rod 3 and stirring blade 35 is adjusted to the state that slowly runs, revolving speed is 26 revs/min.
(4) slurries export: opening the slush pump 20 connecting with the grout outlet 31 of agitator 1, open simultaneously electric butterfly valve 38
Electric butterfly valve 37 is closed, the slurries being stirred in agitator 1 are delivered to and mix and stir host, will be starched by shape spray grout outlet 24
Liquid is sprayed in the mixing cylinder for mixing and stirring host, is allowed to mix and stir with aggregate.
(5) when agitator 1 initially enters step (4), agitator 2 immediately enters ingredient and material stirring step, stirring
The ingredient of bucket 2 and the method for material stirring are identical with the method for mixing and stirring bucket 1, as above-mentioned steps (2) and step (3).
(6) before the slurries output in bucket 1 to be mixed finishes, agitator 2 has completed the whole of ingredient and material stirring
Work.When the slurries residual mass in agitator 1 is 500kg, the electric butterfly valve 38 of agitator 1 need to be immediately closed off, opening is stirred
The electric butterfly valve 37 of bucket 1, and the synchronous slush pump 21 for opening agitator 2 are mixed, opens the electric butterfly valve 30 of agitator 2, closing is stirred
Mix the electric butterfly valve 29 of bucket 2.Continue for it is continual to mix and stir host conveying slurries.It should be noted that the step is not related to
The slush pump 20 for closing agitator 1, continues working, and guarantees remaining serum recycle flowing in agitator 1.
(7) carry out ingredient, material stirring and the slurries of agitator 1 and agitator 2 in a manner of cycle alternation are supplied
The work answered guarantees that slush pump is continuous continual to mixing and stirring host conveying slurries.
Wherein: in the slurries conveying for entering step (4), weighing sensor 17 monitors in real time to be starched agitator 1 in agitator 1
The reduction amount of liquid, and the defeated slurry rate by the conversion of its reduction amount as slush pump, if to the defeated slurry rate of host is mixed and stirred not
It meets the requirements, then control system adjusts the revolving speed of slush pump in real time, until defeated slurry rate is met the requirements.
It, need to be before ingredient next time by the weighing number of weighing sensor after each agitator completes a slurries conveying slurry
Value is zeroed again.
Although be described in detail to a specific embodiment of the invention in conjunction with the embodiments, should not be construed as to this
The restriction of the protection scope of patent.In range described by claims, those skilled in the art are without creative work
The various modifications and deformation that can make still belong to the protection scope of this patent.
