The specific embodiment
In Fig. 1, Fig. 2, a kind of continous way stirs antiseepage earth material blending preparation system, clay hopper 1 and gravel hopper 2 have the ingredients belt 3 that gathers materials, the ingredients belt 3 that gathers materials is connected with weigh-hatching plant 6, weigh-hatching plant 6 has continuous mixer 8, the discharging opening of continuous mixer 8 has and promotes discharging belt feeder 4, promotes discharging belt feeder 4 and is connected with dump skip 5, also is provided with water supply installation 7 on the continuous mixer 8.
Be provided with pressure sensor in the described weigh-hatching plant 6.This pressure sensor can be given master control set, and for example PLC or industrial computer provide signal, with the weight of material in the acquisition weigh-hatching plant 6, thereby supplies water according to this weight.
Described continuous mixer 8 is a Forced Continuous Mixer with Double Axle.
In Fig. 3, Fig. 4, respectively be provided with a dynamic measuring belt conveyer scale under the discharging opening of described clay hopper 1 and gravel hopper 2.The gather materials precision of proportioning belt scale of dynamic measuring is 0.5%, can improve the precision of the batching of gathering materials greatly.Valve opening and closing on the Data Control hopper that obtains with the dynamic measuring belt conveyer scale, thus realize control charge ratio automatically.
Be provided with flowmeter in the described water supply installation 7, be used for obtaining automatic control output data.
Also be provided with vibrating device 9 on clay hopper 1 and the gravel hopper 2, the aggregate vibration motor is connected with the retaining sieve 11 of clay hopper 1 and gravel hopper 2 with described vibrating device 9 in the vibrating device 9, and can solve gathers materials is bonded in the problem that can't freely fall into hopper on the retaining sieve.
Dump skip 5 belows are provided with weighbridge, and dump skip 5 is provided with pressure sensor and/or light sensor.The foundation that the data of obtaining with weighbridge are opened as dump skip 5, only reach the gravimetric value of setting, dump skip 5 just can be opened, to avoid occurring maloperation, the light sensor that is provided with, infrared sensor for example, control point as a supplement, can avoid dump skip the workmen to occur 5 times, cause injures and deaths.The pressure sensor that is provided with is as the foundation of shutting down, with the interim situation of interrupting of reply transportation.
A kind of control method that is used for the described system of claim 1-7 may further comprise the steps:
1) in PLC or industrial computer, sets relevant control parameter, the equipment in the open system.
2) at first open the magnetic valve of clay hopper 1, to dynamic measuring belt conveyer scale 10 feed under it, simultaneously or after period, according to dynamic measuring belt conveyer scale 10 feed amounts, open the magnetic valve of gravel hopper 2, give dynamic measuring belt conveyer scale 10 ' feed under the gravel hopper 2 according to the ratio of designing requirement; Adopt the foundation of the dynamic measuring belt conveyer scale 10 conduct batchings under the clay hopper 1 in this example, but adopting the data of gravel hopper 2 is feasible also as foundation, but because clay material is vulnerable to Effect of Environmental, humidity for example, gravel material then is not subject to such environmental effects, feed is comparatively reliable, so the feed amount of adjusting gravel material according to the feed amount of clay material is the technical scheme of comparatively optimizing.For avoiding occurring the vibration in the control automatically, guarantee the proportioning of clay material and gravel material, can at the drop point of the ingredients belt 3 that gathers materials a segment distance be set to drop point and the dynamic measuring belt conveyer scale 10 ' of dynamic measuring belt conveyer scale 10 on the ingredients belt 3 that gathers materials, promptly provide the time of the solenoid control buffering on the gravel hopper 2, to guarantee the reliability of control automatically, reduce the difficulty of control automatically.
