Description
Technical field the utility model relates to a kind of automatic liquid matching device.
Background technology at present domestic and international various automatic liquid matching devices (system) generally all adopts the proportional arrangement of weighing, and the weight of each composition in promptly filling a prescription according to proportioning adds together obtaining to after it is weighed successively.It mainly exists the defective of the following aspects: 1, the weighing and proportioning precision is subjected to ancillary equipment (as electronic scale etc.) restriction; 2, owing to instruments of weighing such as employing electronic scales, its shockproof properties is relatively poor; 3, infusion pipeline generally adopts plastic raw materials to make, and its coefficient of thermal expansion and contraction is big, directly influences proportioning speed; 4, device (system) antimagnetic poor performance; 5, various mother liquor raw materials inject in turn during proportioning, after promptly a kind of mother liquor raw material adds, add other mother liquor raw material in the prescription more successively, and proportioning speed is slow; 6, having relatively high expectations to the control magnetic valve.
Utility model content technical problem to be solved in the utility model is to propose a kind of distributing precision height, proportioning speed is fast, shockproof, antimagnetic, humidity resistance is good, adaptive temperature wide ranges, easy to operate automatic liquid matching device.
For solving the problems of the technologies described above, the utility model automatic liquid matching device, comprise control system, the control motor, motor control unit, screw mandrel, slide block, airtight container and support, pressure ram, magnetic valve, the solenoid-driven unit, the mother liquor reservoir vessel, dosing connects liquid container and rotating disk etc., described motor control unit is controlled the running of described control motor, described screw mandrel is driven by the output shaft of described control motor, one end of described each pressure ram is fixed on the slide block, this slide block is screwed onto with described screw mandrel, one end of the described airtight container of the airtight insertion of the other end of described each pressure ram, the other end of described each airtight container is connecting two magnetic valves respectively, one of them magnetic valve is used for the connection between each airtight container and the corresponding mother liquor reservoir vessel, and another magnetic valve is used to control extruding of mother liquor; Liquid in each airtight container connects in the liquid container by extruding magnetic valve inflow dosing; Motor control unit and solenoid-driven unit are controlled by control system, and the keying of each magnetic valve is by described solenoid-driven unit controls.
Owing to adopted above-mentioned technical pattern, during dosing, finish feed liquor by control system earlier, that is to say that the closeall magnetic valve of extruding is opened all liquid inlet electromagnetic valves, by the control motor pressure ram is drawn out to given dominant bit from seal.According to the weight content of different components in the prescription, calculate the corresponding stroke of extruding of required respective volume and pressure ram again.By the prescription requirement, open extruding magnetic valve and closing the liquid inlet electromagnetic valve of all required mother liquors of all required mother liquors, close all and do not need extruding magnetic valve and opening the liquid inlet electromagnetic valve that all do not need mother liquor of mother liquor.Then, extrude the stroke of operation by control system according to the minimum required mother liquor needs pressure ram of volume, the rotation of control control motor drives the screw mandrel rotation, drives the pressure ram horizontal sliding forward in the airtight container.Required mother liquor flow into dosing and connect in the liquid container this moment, did not need mother liquor to refund in the original mother liquor reservoir vessel.After the required mother liquor of minimum is extruded stroke and is finished, stop to control motor and rotate, close extruding magnetic valve and opening the liquid inlet electromagnetic valve of this mother liquor correspondence of this mother liquor correspondence, this mother liquor is refluxed, stop to continue to allocate into, finish the given of the required mother liquor amount of minimum.Continue to drive the rotation of control motor then, drive pressure ram and continue reach, after second a spot of required mother liquor is extruded stroke and is finished, stopping to control motor rotates, close extruding magnetic valve and opening the liquid inlet electromagnetic valve of this mother liquor correspondence of this mother liquor correspondence, this mother liquor is refluxed, stop to continue to allocate into, finish the given of second a small amount of required mother liquor amount.Then by that analogy, finish respectively the 3rd a small amount of ... the required pressure ram of liquid components of volume extrude operational stroke.If when once advancing whole process all not finish the amount of all required mother liquors, according to surplus, can repeatedly repeat aforesaid operations, all flowing into dosing up to the aequum mother liquor with maximum components connects in the liquid container, connect liquid container thereby the aequum of each component in proportioning is all injected dosing, finish the automatic mixing work of a prescription.Therefore, use automatic liquid matching method and apparatus of the present utility model, overcome the deficiency of in the existing matching method (device) the each component gradation being injected in turn, not only proportioning speed is fast, the distributing precision height, and also operation is very easy.Because matching method and device are the weight of calculating each component in the prescription according to volumetric method, there are not to use in the existing method the generally weight metering instruments such as electronic scale of employing of institute, avoid defective, and it is shockproof, antimagnetic, humidity resistance is good by the weighing proportioning deficiency of its generation.Airtight container that is adopted in the utility model device and pressure ram are to adopt corrosion resistant metal material or the little nonmetallic materials of coefficient of thermal expansion to make, the configuration precision factor affecting of can not expanded with heat and contract with cold, and temperature accommodation is wide.
Description of drawings is described in further detail the utility model below in conjunction with drawings and embodiments.
