Among Fig. 13,4 are respectively single or multiple cement and powder (flyash) storage bin, cement and powder are sent into continous way cement automatically from storage bin respectively, powder proportioning machine 17 and 15, both operation principles are consistent with structure, the continous batching machine is by hopper, weighing sensor is formed, its hopper lower part outlet place is provided with the rotation plate washer of driven by motor, cement that plate washer is sent when motor speed increases or powder quantity just increase, otherwise reduce, computer automatic control system is according to predefined raw material ratio requirement, calculate cement in the proportioning machine hopper with the decrement method, the weight change of powder, the self-regulation motor rotating speed, accurate with the quantity delivered that guarantees its cement and powder, evenly, stable.Cement, powder can be by gathering materials spiral or directly raw material is delivered on the conveyer belt 16 that carries two-layer raw material as shown in the figure, and belt conveyor is connected to the inlet of New agitator 14.

At belt conveyor when a mixing bowl feeds intake, water and additive also press the raw material ratio requirement with stable speed to the mixer feed: 5 is the additive case among Fig. 1,6 is that water pump, 8 is the additive batch meter, this batch meter is provided with LOAD CELLS, adopt decrement method metered flow by automatic control system, by predefined ratio requirement, by the flow in water pump 6 and its input mixer of adjusting control valve 7 controls.12 is water tank, and 11 is flowmeter, and automatic control system is according to predefined water requirement, and process suction pump 10 and control valve 9 control and regulation are to the water supply flow of 14 li in mixer.

It is emphasized that the most important breakthrough of the utility model patent is to have adopted New agitator 14, New agitator 14 is being accepted with stable flow velocity (per second flow), equally distributed all raw materials of proportioning accurately, continuous stirs, forming raw material continuously flows through and produces the process of working continuously of cement concrete behind the mixer, the time of feed stream through stopping in a mixing bowl in the mixer is exactly clean mixing time, because the label difference of cement, raw material are different with the proportioning value, when producing cement concrete in mixer the difference of required clean mixing time change greatly, the utility model patent can satisfy this requirement fully, and can adjust control because of product variations changes clean mixing time.This New agitator is that mixing time controllable type, low speed are forced the continuous concrete New agitator, can be single horizontal shaft type, also can be the dual horizontal axle, and its operation principle and structural representation are as each shown in 2,3,4,5.

Fig. 2 is a single horizontal shaft type, and Fig. 3 is a dual horizontal shaft type mixer, and the dual horizontal axle is the combination of 2 single horizontal axis, and principle is consistent with single structure, and dual horizontal shaft type mixer output is bigger, and the stirring dynamics is also strengthened to some extent.Be that example describes with the dual horizontal axle now: 21 is a mixing bowl among Fig. 3, also be provided with parallel in a mixing bowl 21 with shaft 22A, but the shaft of switched in opposite (22B), the vertical respectively mixing arm (23) that the single stirring vane (24) that parallel unanimity of working face or not parallel unanimity are housed is set on shaft (22A) and (22B), the quantity of mixing arm 23 is selected according to cement concrete design output, adjacent mixing arm 23 and on stirring vane 24 circumferentially evenly staggering mutually along shaft 22A, 22B.And the center line of adjacent mixing arm 23 evenly distributes along the axial spacing distance of shaft 22A, 22B, and the rotating speed of shaft 22A, 22B adopts the slow-speed of revolution below 40 seconds/minute, but rubbing between the evidence strength imparting material and stirring and easy break-down not.

For material is promoted forward under stirring vane stirs automatically, the cement concrete that stirs is sent from discharging opening automatically, keep certain included angle between the axial line of the working face of stirring vane 24 and shaft 22A, 22B.

A mixing bowl 21 upper front end are provided with a feeding mouth, are provided with LOAD CELLS 26 on lower posts, and exit, its underpart is provided with rotary type Dump gate 27.As shown in Figure 4, rotary type Dump gate 27 can be made as single fan, two fans or many fans, with two fan rotary type Dump gate is example: its Dump gate 27 can be through hydraulic unit 29, movable link rod 28 drives, respectively rotate same angle synchronously to the left and right, make it closely close and open, there be 3-7 aperture rank available when opening, make its rotary type Dump gate 27 that the aperture of 3-7 different stage be arranged, also can be set as the step-less adjustment aperture, what can have level or stepless adjustment from this quantity that draws off to make cement concrete in a word, and Fig. 4 is the structural representation of full closing state, Fig. 5 is the structural representation of full open state, this Fig. 4, Fig. 5 is that the A of Fig. 3 is to view.

When Dump gate is closed, the raw material volume (weight) of input a mixing bowl must not surpass the maximum stirring raw material volume that allows and limit the quantity of, at any time automatic control system is all strict is controlling the raw material total measurement (volume) (or weight) of importing a mixing bowl and must not surpass this scope of limiting the quantity of, it is above-mentioned that to have mentioned clean mixing time be exactly raw material time of staying in a mixing bowl, after mixer starts, Dump gate should be in off position, this moment, automatic control system began to clock to the moment that a mixing bowl feeds intake at defeated material belt, up to the moment that Dump gate is opened is exactly the time that material stops in mixer, be the clean mixing time of raw material, after Dump gate is opened, cement concrete draws off from Dump gate with certain speed, the aperture of automatic control system rapid adjustment Dump gate to be keeping discharge rate consistent with charging rate, kept stablizing constant thereby make Dump gate open the clean mixing time that moment writes down.

The foundation of the selected aperture size of automatic control system is: open moment in Dump gate, computer automatic control system is write down whole mixer weight by LOAD CELLS 26, and deduct mixer deadweight, note the weight of interior all materials of this moment a mixing bowl, and be pivot weight as regulating intermediary with this weight, aperture size with Dump gate keeps its pivot weight constant, owing to open and to have set the capacity (or weight) that productivity ratio is promptly per hour produced cement concrete before the stirring system work, the continous way stirring system has been determined charging rate with regard to corresponding, automatic control system is with the uniform charging of velocity-stabilization that keeps setting, when pivot weight reduces, illustrate that the Dump gate aperture is excessive, the material that draws off is too many, automatic control system just reduces the aperture of Dump gate, otherwise illustrate that the material that draws off very little, the material that enters in a mixing bowl is long-pending to some extent folded, automatic control system just strengthens the Dump gate aperture, after the trace adjustment, reach dynamic equilibrium rapidly, it is stable that pivot weight can keep, the raw material total amount that therefore just can guarantee to enter a mixing bowl is consistent with the cement concrete total amount that draws off, be charging rate and discharge rate basically identical, and remain on the level that Dump gate is opened moment, therefore time of stopping in a mixing bowl of the material of flow path a mixing bowl just can remain on the clean mixing time that Dump gate is opened moment, and automatic control system has enough sensitivity to keep clean mixing time to stablize.

Clean mixing time desired control accuracy rating broad, evidence the utility model mixing plant clean mixing time that can keep setting is enough to satisfy the work on the spot needs in ± 5% error range after tested.

The factor that influences clean mixing time is more, and the principal element of the clean mixing time of regulation and control has two in production practices, and the relational expression between them is:

T=Q/η

T=stirs (minute, second) only

Q=is stirred raw material total measurement (volume) (m in a mixing bowl 3) or weight (kilogram)

η=productivity ratio is the raw material total amount (m of (or dividing or second) input a mixing bowl per hour 3, kilogram) or the cement concrete output (m of (or divide or second) output per hour 3, the kilogram).

Its Q and η maximum limit value are also just determined after the utility model patent one model is determined, in use whenever should not surpass its limit value.

Now be 240m with the peak performance 3/ hour mixing time controllable type continous way mixing plant be example, illustrate that it is in the clean mixing time of minimum 15 seconds and 120 seconds the stirring system course of work of maximum net mixing time.

This kind of mixing plant performance data regulation: it is 3m that the raw material volume is stirred in its maximum permission 3, peak performance is per minute 4m 3, starting stirring system needs to set this production stirring output to computer automatic control system before, clean mixing time, and require to produce with great productivity ratio.When setting these parameters, in operating process, whenever should not exceed any data in above-mentioned two performance datas regulation, can only be in above-mentioned performance data scope with interior running, simultaneously should be when setup parameter according to clean mixing time T, productivity ratio η and send into relation character between the raw material capacity that the is stirred Q of a mixing bowl and close and state relational expression promptly:

T = Q η

Now setting this output is 300m 3, clean mixing time is 15 seconds, sets productivity ratio and should be maximum permissible value 4m 3/ minute below, if selected maximum is 4m 3/ minute produce, so for the continous way stirring system, its raw material is sent into a mixing bowl, and must to adopt maximum feed velocity be 4m 3/ minute, start mixing plant after, automatic control system closes Dump gate, make delivery material system by the raw material ratio requirement with per minute 4m 3Speed feed intake to a mixing bowl, and clock in the moment that feeds intake to a mixing bowl, reaching the certain aperture discharging of Dump gate unlatching in the time of 15 seconds of clean mixing time, the raw material that enters a mixing bowl this moment also has been stirred 15 seconds and has reached outlet successively, has formed the cement concrete qualified products.Therefore form the technical process that continuous feed goes out product continuously, under the regulation and control of automatic control system, the aperture of Dump gate always guarantees that the raw material weight (capacity) in a mixing bowl is exactly to open the Dump gate weight of moment, and keep this pivot weight constant, thereby guarantee the discharge rate and charging rate (the per minute 4m of Dump gate with the change of Dump gate aperture 3) consistent, material will be that 15 seconds requirement continuous operation can be finished cement concrete production after 75 minutes 15 seconds by clean mixing time.By the above-mentioned relation formula in process of production the raw material total amount in a mixing bowl 1m is arranged all the time 3Raw material stirring.If set productivity ratio is per minute 3m 3, clean mixing time is 15 seconds, and 0.75m is arranged in a mixing bowl so all the time 3Raw material after stirring 100 minutes 15 seconds, finish cement concrete production.

If adopted the maximum net mixing time 120 seconds: be no more than 3m in order to guarantee the raw material total amount in Dump gate is opened moment input a mixing bowl 3, can select less productivity ratio for use, set productivity ratio 1.5m this moment 3/ be divided into rationally.Also can set productivity ratio is 1m 3/ minute, but this is arranged on clean mixing time and reaches 120 seconds, and Dump gate is opened moment, and 2m is only arranged in a mixing bowl 3Raw material is stirring, obviously not performance fully of this production efficiency.So selected 1m 3/ minute productivity ratio is not preferred plan, use in the operation in reality, the parameter that is provided with to computer automatic control system is (in the preferred plan scope) in the reasonable scope, when the user sets value unreasonable or is not the best, the automatic control system of the utility model mixing plant can be sent warning signal, assists the user correctly to select each parameter for use.Under above-mentioned setting, can finish 300m in 202 minutes 15 seconds 3The cement concrete production task.

As above-mentioned with 1.5m 3/ minute the charging rate continous-stable uniformly to a mixing bowl feeding, when the moment that reaches 120 seconds clean mixings time, the material volume in the cylinder is whole to be reached maximum and allows to be stirred raw material capacity 3m 3, this moment, automatic control system was opened Dump gate, and kept in a mixing bowl 3m being arranged all the time by regulating and control its aperture 3Material, the cement concrete that draws off from Dump gate are all the time according to 120 seconds clean mixings time are arranged.When the stirring task was finished, the apolegamy system quit work, and a mixing bowl inlet stops feed, and clout is also stirring in a mixing bowl, and Dump gate is still in discharging, and the raw material weight in a mixing bowl descends.Dump gate should turn down aperture automatically even can close this moment, finished for the material tail is stirred smoothly, and automatic control system stops moment of charging at a mixing bowl, keeps Dump gate to have certain aperture unlikely to the closed position automatically, during whole end-of-job it was closed.

What be worth emphasizing is that production method that clean mixing time is controlled in the adjustment of the utility model patent has also overcome in the past the nonadjustable continuous mixer of clean mixing time when the continuous stirring cement concrete, stub bar appears, shortcoming off quality, old continuous mixer is when starting stirring work, discharging opening is opened all the time, discharging opening is without any control and adjustment automatically, when beginning to start stirring work, raw material just can fill up a mixing bowl after having one section space to need charging a period of time in a mixing bowl, so when beginning to stir, do not form extruding and rubbing in a mixing bowl between each raw material, stub bar does not also stir fully and just is pushed out, thereby it is off quality to form stub bar, new mixer is after startup work, Dump gate is closed, just open reaching predefined clean mixing time, and be to keep the total amount of the interior raw material of this moment a mixing bowl not change, its Dump gate is constantly changing aperture, keep charging rate consistent with discharge rate, can not form between each raw material very sparse and do not form the extruding and the rubbing phenomenon, thereby guaranteed all raw material mixing qualities.

Original continuous concrete mixing plant over nearly 30 years the scope of application be restricted, many advantages of policy guidance that meet now can not get performance, root problem is in that to do its clean mixing time little and non-adjustable, the utility model prolongs the clean mixing time of continuous concrete mixing plant and is adjustable, reaches the on all four level of gap mixing plant now.The various advantages of continous way mixing plant are fully played.This is the important breakthrough of cement concrete production Technology, it is the great achievement of cement concrete production equipment development and production industry, the birth of mixing time controllable type continuous concrete mixing plant (building) and promoting the use of, the looks of China's cement concrete production industry will thoroughly be changed, create the cement concrete low energy consumption in the world, efficiently, the ground zero of low-cost production, the new situation.
