Description
One, technical field
The utility model relates to a kind of stabilized soil mixing plant with cement Weighing device.
Two, background technology
As everyone knows, stabilized soil mixing plant generally needs simultaneously various materials to be carried out grating, metering, mixing, to produce the finished product material, the quality of grating uniformity and finished product material not only is subjected to the physical property of feed machinery, feed mode and material, but also be subjected to the influence of weather conditions etc., wherein the problem of most critical is the measure control of cement feed.At present, generally weigh control mode such as belt claims, decrement claims of the cement-weighting of stabilized soil mixing plant, and two kinds of volume measurement modes, the control mode of weighing is because the reliability and the degree of accuracy are not high, the member rapid wear, seal is poor, cement easily disperses or make moist now less use; The stabilized soil mixing plant of domestic production adopts the volume measurement method that cement is measured mostly, as the rotating speed by control feed spiral or rotary vane valve, controls the flow of cement.Overseas equipment also has part to adopt the volume measurement technology, the equipment of producing as the higher Australian ARAN company of popularity, what adopt is flute profile rib belt feed, it is the effect that reaches control feed weight by the feed volume in the control unit interval, and its essence also is the volume measurement method.Under the volume measurement state, when feed is unusual such as cement bin lack material, cement gravity flow, equipment can not in time be reacted, and causes the finished product material inhomogeneous easily, has influenced quality.Simultaneously,, caused the waste of the higher material of this price of cement, increased cost because volume measurement can't accurately be controlled the quantity delivered of cement.
Three, summary of the invention
The purpose of this utility model is a kind of stabilized soil mixing plant with cement continuous weighing metering function of design.
The stabilized soil mixing plant of the continuous weighing metering of the utility model design comprises frame, cement silo, feed screw machine, agitating device, finished product material conveying device and finished product bin, and the feed screw machine is used to carry cement by what motor for feeding drove; Be to realize the continuous weighing metering function, this equipment also is provided with spiral weighing device and computer control device, and the spiral weighing device comprises that inside is provided with the screw machine of weighing of spiral, is used to measure the screw machine weight change and be converted into the sensor of the signal of telecommunication of weighing; The charging aperture of screw machine of weighing is communicated with the discharging opening of feed screw machine, and spiral is by carrying motor-driven, being used to transmit cement material, and the discharging opening of the screw machine of weighing is used for cement is sent into agitating device; Motor for feeding and sensor all are electrically connected with computer control device, and computer control device comprises with the Programmable Logic Controller being the control core circuit.
This equipment has been set up spiral weighing device and computer control device, therefore can be automatically, continuously the cement feed is measured, controls, the accuracy of grating is reached ± 1% magnitude, not only guaranteed the quality of Stabilized Soil, also avoid the waste of cement, reach the purpose of saving cost.Simultaneously,, overcome the shortcoming that open belt claims device, had higher reliability and practicality because the screw machine sealing of weighing is fine.
Four, description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structure chart of the stabilized soil mixing plant of the utility model continuous weighing metering.
Fig. 2 is the structure chart of spiral weighing device among Fig. 1.
Fig. 3 is the circuit theory diagrams of computer control device.
Five, the specific embodiment
As shown in Figure 1, the stabilized soil mixing plant of continuous weighing metering comprises frame 1, cement silo 2, feed screw machine 3, agitating device 4, finished product material conveyer 5 and finished product bin 6, also is provided with spiral weighing device and computer control device 7 in this equipment.Cement silo 2 is used to adorn cement material, and a blocking rotary type level-sensing device respectively is equipped with in the upper and lower limit position of feed bin, with the cement amount in the monitoring storehouse.The charging aperture of feed screw machine 3 links to each other with the discharging opening of cement silo 2, is provided with the feed spiral in the feed screw machine 3, and the feed spiral transmits cement material by motor for feeding 17 drive work, and motor adopts converter technique to carry out stepless speed regulation with the control quantity delivered.Feed screw machine 3 becomes an inclination angle with horizontal plane, and is provided with one section buffering area 19 in the exit, can prevent the gravity flow of cement effectively, guarantees stability of flow.According to the feed needs, the pitch of choose reasonable feed spiral and the size of blade are to guarantee the continous-stable feed and can the signal that computer control device 7 is sent in time be responded.
As shown in Figure 2, the spiral weighing device comprises weigh screw machine 8 and pull-type sensor 9, and the screw machine 8 of weighing is the inner tubular style structure that is provided with spiral, is the deadweight that alleviates the screw machine 8 of weighing and attractive in appearance, and cylindrical shell is selected stainless steel for use.The cylindrical shell of screw machine 8 of weighing is provided with charging aperture 10 and discharging opening 11.Charging aperture 10 is communicated with the discharging opening of feed screw machine, and spiral is by carrying motor 12 to drive, be used to transmit cement material, and discharging opening 11 is used for cement is sent into agitating device 4.Weigh external diameter, the pitch of screw machine 8 spirals should cooperate selection with the feed spiral, to guarantee the continous-stable feed.Pull-type sensor 9 is by the weigh weight change of screw machine 8 of measurement, can change the instantaneous weight of the cement of continuous-flow to detect, and after this variation is converted to the signal of telecommunication, deliver to computer control device 7 by lead.
The operation principle of computer control device 7 as shown in Figure 3, the signal of telecommunication that sensor 9 is sent here by transmitter 13 become veer away big, be converted to data signal by analog to digital conversion circuit 14 again, data signal is sent into Programmable Logic Controller PLC and is carried out calculation process, when actual flow greater than when setting value, Programmable Logic Controller PLC output signal reduces, and is converted to analog signal by D/A converting circuit 15, by frequency converter 16 output frequency signals, motor for feeding 17 rotating speeds are descended; Otherwise, when actual flow less than when setting value, the signal of Programmable Logic Controller PLC output increases, and motor for feeding 17 rotating speeds are strengthened, and reaches the purpose of control mass flow.18 pairs of whole operation processes of industrial computer are carried out visualization display, control, also have multinomial functions such as printout, data statistics, debugging and troubleshooting simultaneously.
