Description of drawings
Fig. 1 is the apparatus structure sketch map of a kind of automatic ration annex solution of the present invention material.
Be labeled as among the figure: cylinder chamber 1, piston body 2, piston cylinder 3, liquid material input pipe 4, liquid material efferent duct 5, end socket 6, transfer passage 7, stopper 8, input port 9, delivery outlet 10, permanent magnets 11, electromagnetic induction detecting element 12, PLC control module 13.
The specific embodiment
As shown in Figure 1 is the device of the automatic ration annex solution material of a kind of volume that can directly measure the liquid material that need to add provided by the invention.The device of said automatic ration annex solution material is included in the piston cylinder 3 that is provided with piston body 2 in the cylinder chamber 1, is provided with liquid material input pipe 4 and liquid material efferent duct 5 respectively simultaneously at the two ends of piston cylinder 3.It is above-mentioned through a piston cylinder 3 that is provided with liquid material input pipe 4 and liquid material efferent duct 5 at two ends is set; When needs during to reactor annex solution material; In the cylinder chamber 1 of piston cylinder 3, import the liquid material through liquid material input pipe 4 from an end; Promote piston body 2 and move, the liquid material that originally was stored in the cylinder chamber 1 is added to the reactor from the liquid material efferent duct 5 of the other end to the other end.Because the volume of the cylinder chamber 1 of piston cylinder 3 is changeless; Like this; Each liquid material that in reactor, adds just can be directly volume through cylinder chamber 1 measure, need be as existing proportioning valve, the volume of liquid material is obtained in passing ratio calculating indirectly.Thereby guaranteed each interpolation liquid material quantity accurately, guaranteed reaction fully, effectively and safety.
In the above-mentioned embodiment; In order to simplify the structure of piston cylinder 3; Reduce production costs, simultaneously, the also setting and the installation of liquid material input pipe 4 and liquid material efferent duct 5 for ease; The two ends of cylinder chamber 1 are through end socket 6 sealings, and said liquid material input pipe 4 is arranged on the described end socket 6 with liquid material efferent duct 5 respectively simultaneously; The liquid material input pipe 4 and the liquid material efferent duct 5 that are provided with on said each end socket 6 all have the same transfer passage 7 that is communicated with cylinder chamber 1, on each root liquid material input pipe 4 and liquid material efferent duct 5, are provided with stopper 8; Has same input port 9 with the liquid material input pipe 4 that the different ends of piston cylinder 3 connect respectively; Have same delivery outlet 10 with the liquid material efferent duct 5 that the different ends of piston cylinder 3 connect respectively, stopper 8 is installed on the liquid material input pipe 4 between transfer passage 7 and the input port 9 respectively and on the liquid material efferent duct 5 between transfer passage 7 and the delivery outlet 10.In addition; The liquid material input pipe 4 and liquid material efferent duct 5 shared transfer passages 7 of same end; The liquid material input pipe 4 of different ends and liquid material efferent duct 5 respectively shared input ports 9 and a shared delivery outlet 10; More letter is gathered, occupation of land face is littler can to make the structure of device of automatic ration annex solution material of the present invention, and then more convenient said device layout in process of production.
In the above-mentioned embodiment; Automatic control for the ease of said liquid material adding set; Reduce labor intensity of operating personnel, improve the control that the liquid material adds precision, said liquid material adding set also comprises permanent magnets 11 and electromagnetic induction detecting element 12, and end socket 6 is the permeability magnetic material end socket; Permanent magnets 11 is installed in the piston body 2, and electromagnetic induction detecting element 12 is installed in the end of the cylinder chamber 1 at piston cylinder 3 two ends respectively; Said stopper 8 adopts solenoid electric valve; Also comprise the automatic control system that contains PLC control module 13, the free end of the solenoid electric valve and the control line of electromagnetic induction detecting element 12 is connected with PLC control module 13.Like this; When in the cylinder chamber 1 of piston cylinder 3, filling with the liquid material from an end through liquid material input pipe 4; The other end is during through the whole liquid material in the former cylinder chamber 1 that is stored in piston cylinder 3 of liquid material efferent duct 5 output, and permanent magnets 11 cooperates with electromagnetic induction detecting element 12, to PLC control module 13 input signals; The corresponding solenoid electric valve of PLC control module 13 commanders opens and closes, and realizes one time the liquid feeding material.Then, as required by the reciprocal difference end input liquid material of above-mentioned process from piston cylinder 3, output liquid material, and realized in reactor annex solution material accurately.Certainly, described structure also can be in the cylinder chamber 1 of piston cylinder 3, to fill with the liquid material from an end through liquid material input pipe 4; The other end is during through the whole liquid material in the former cylinder chamber 1 that is stored in piston cylinder 3 of liquid material efferent duct 5 output; Because solenoid electric valve invention signal opens and closes corresponding solenoid electric valve by manually-operated, the automaticity that is this structure is relatively low; Labour intensity is relatively large, and production efficiency is just not high yet.
For the ease of the structure of the device of understanding automatic ration annex solution material of the present invention, the operation principle of said device is done one simply says at present, and respectively each solenoid electric valve is numbered, respectively number and see accompanying drawing 1 for details.
On the liquid material input pipe 4 that is connected with piston cylinder 3, be furnished with normally closed solenoid electric valve L1, L4 respectively, be furnished with normally closed solenoid electric valve L2, L3 on the liquid material efferent duct 5.When L1, L3 solenoid electric valve get when electric, solenoid electric valve is connected, and the liquid material gets into the cylinder chamber 1 of piston cylinder 3 from left end through the L1 solenoid electric valve, promote piston body 2 toward moving right, thereby the liquid material that will originally be stored in the cylinder chamber 1 is discharged through the L3 solenoid electric valve; When piston body 2 moved to right-hand member, permanent magnets 11 cooperated the position that detects piston body 2 with electromagnetic induction detecting element 12, and through in the PLC control module opening control near switch; That is, magnetic valve L1, L3 dead electricity are closed, L2, L4 get electric connection; Like this; The liquid material gets into the cylinder chamber 1 of piston cylinder 3 from right-hand member through the L4 solenoid electric valve again, promotes piston body 2 and moves to left, thereby the liquid in the cylinder chamber is discharged through the L2 solenoid electric valve in fact.When piston body 2 moved to left end, permanent magnets 11 cooperated the position that detects piston body 2 again with electromagnetic induction detecting element 12, and through PLC control module opening control interior near switch; Promptly; Magnetic valve L2, L4 dead electricity are closed, and L1, L3 get electric connection, so back and forth.Because permanent magnets 11 is arranged in the piston body 2, end socket 6 is processed for permeability magnetic material, thus piston body 2 start bits always at an end of the cylinder chamber 1 of piston cylinder 3, thereby what make piston cylinder 3 each strokes discharge all is the liquid material of a cylinder chamber 1.
In sum, adopt the device of the automatic ration annex solution material of structure of the present invention can carry out that constant volume is long-pending directly to be measured to the volume of the liquid material that added; The volume accuracy of the liquid material that adds does not receive transfer pipeline pressure, flow restriction by the cavity volume precision control that is designed, and precision stability is good; And simple in structure, easy row, good economy performance.
