Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model original position liquid medicine injection system.
Detailed description of the invention
Below in conjunction with accompanying drawing and concrete case study on implementation, the original position liquid medicine injection system that the utility model provides is described in further details.
As shown in Figure 1, a kind of original position liquid medicine injection system, mainly comprises water tank 1, drug dissolving tank 7, medicine tin 12, water-delivery pump 3, hydraulic pipeline 2, killer injecting pump 14 and injection pipeline 24.
Wherein, water tank 1 is communicated with drug dissolving tank 7, medicine tin 12 respectively by two branch roads (branch road 8 and branch road 11) of hydraulic pipeline 2, and controls water inlet and inflow by the magnetic valve 26 on water-delivery pump 3 and branch road 8, magnetic valve 28 on branch road 11.Hydraulic pipeline 2 is also provided with ball valve 4, for opening and closing hydraulic pipeline 2.
As shown in Figure 1, the top of drug dissolving tank 7 is provided with feeding opening 5, for adding reparation medicament; Top is also provided with water inlet, is connected with the branch road 8 of hydraulic pipeline.Be provided with agitator 6 in drug dissolving tank 7, agitator 6 is made up of stirring motor and oar, for stirring reparation medicament, promotes the dissolving of repairing medicament.The bottom of drug dissolving tank 7 is provided with drug row mouth, when cleaning tank body after being convenient to injection, and the discharge of unnecessary liquid and cleaning waste water.Drug dissolving tank 7 is also provided with liquid level gauge 10, is convenient to the volume variation observing liquid in drug dissolving tank 7.The top of drug dissolving tank 7 is also provided with loading pipeline 9, is pumped in medicine tin 12 by the reparation medicament dissolved, preserve by kinetic pump 27.
The top of medicine tin 12 is also provided with water inlet, and water inlet docks with the branch road 11 of hydraulic pipeline, and the bottom of medicine tin 12 is communicated with injection pipeline 24.Medicine tin is provided with liquid level gauge 13, is convenient to the Volume Changes observing liquid in medicine tin 12.
Medicine-pouring port 23 is crossed by two bye-passes and forms: the arm 16 of injection pipeline 24 and hydraulic pipeline.
The arm 16 of hydraulic pipeline is connected with water tank 1 by hydraulic pipeline 2, arm 16 is provided with first flow pressure control mechanism, this controlling organization comprises pressure sensor 20, magnetic valve 21, electromagnetic flowmeter 22, check-valves 25, water can be delivered in injection pipeline 24 by arm 16, thus realizes the concentration of repairing medicament in on-line dilution injection pipeline.Check-valves 25 can prevent medicament from flowing backwards when arm 16 is idle.
Injection pipeline 24 is provided with killer injecting pump 14 and the second flow pressure controlling organization, and this controlling organization comprises magnetic valve 15, pressure sensor 18, electromagnetic flowmeter 19.Above-mentioned magnetic valve 15,21,26,28 controls by PLC control cabinet 17, realizes the control of the water yield, is carried out the adjustment of water delivery, injection ratio by the reading information of pressure sensor and flowmeter, and the concentration realizing delivery of medicaments controls.PLC control cabinet 17 also controls the opening and closing of the motor such as water-delivery pump 3, killer injecting pump 14.
The using method of above-mentioned original position liquid medicine injection system is as follows:
Be positioned at after full water state until water tank, open ball valve 4, open magnetic valve 26, open water-delivery pump 3 and carry out water delivery.Added in drug dissolving tank 7 by dosing mouth 5 and repair medicament, turn on agitator 6 stirs, and inflow and mixing time are arranged by PLC control cabinet 17.After medicament dissolution in drug dissolving tank 7, be delivered in medicine tin 12 by loading pipeline 9 by kinetic pump 27, observed the liquid level change of drug dissolving tank 7 and medicine tin 12 by liquid level gauge 10 and liquid level gauge 13, after making up a prescription, valve in above flow process is closed successively, enters injection process.
Can adopt and carry out injection in two ways, be respectively:
(1) for the contaminated site (and some position) that pollution level is serious, the concentration of repairing medicament prepares disposable putting in place, and do not dilute reparation medicament in injection process, namely during injection, arm 16 and controlling organization thereof are in closed condition.Open killer injecting pump 14, by medicine-pouring port 23, medicament is injected in pending soil, completes injection.
(2) for the contaminated site (and some position) that pollution level is lighter, during injection, opens solenoid valve 21, killer injecting pump 14 and water-delivery pump 3, by the display data of pressure sensor 20,18 and electromagnetic flowmeter 22,19, PLC control cabinet 17 is set, carry out the quantitative output of Controlling solenoid valve 21 and 15, thus the different proportion realizing carrying capacity and dosing regulates.Water in water tank 1 is confluxed by the reparation medicament flowed out in hydraulic pipeline 2 and arm 16 and injection pipeline 24, thus plays the effect regulating and repair drug concentration.Repair after medicament confluxes and by medicine-pouring port 23, medicament is injected in pending soil, complete injection.
When the liquid level in drug dissolving tank 7 is in low liquid level, opens magnetic valve 26 and added water by branch road 8 pairs of drug dissolving tanks 7; When the liquid level gauge liquid measured in drug dissolving tank 7 arrives high liquid level, shut electromagnetic valve 26, turn on agitator 6 carries out stirring and the dissolving of medicament, and after stirring arrives setting dissolution time, agitator quits work.
When the medicament of medicine tin 12 is in low liquid level, the kinetic pump 27 between drug dissolving tank 7 and medicine tin 12 is opened automatically, is sent to by the medicament dissolved in medicine tin 12, when the medicament in medicine tin 12 arrives high liquid level, quits work.
After equipment use, close killer injecting pump 14, open the valve of the injection pipeline 24 be communicated with medicine tin 12 drug row mouth with drug dissolving tank 7, in tank, the waste water of residual medicament and cleaning tank body is discharged by medicine-pouring port 23.
The all devices of above-mentioned original position liquid medicine injection system can be integrated with on transport vehicle, convenient mobile, applied widely, injection efficiency is high, can carry out the reparation of specific aim quantitative dosing, prevent excessive reparation for the soil of different pollution level and underground water, science applies to repair dosing, both be applicable to contaminated soil and underground water focuses on a large scale, and the in-situ immobilization of contaminated soil and underground water can have been realized again, there is good environmental benefit and social benefit.
