Detailed description of the invention
That a kind of automatic ration that can directly measure the volume that needs the liquid material of adding provided by the invention adds the device of liquid material as shown in Figure 1.The device that described automatic ration adds liquid material is included in the piston cylinder 3 that is provided with piston body 2 in cylinder chamber 1, is provided with respectively liquid material input pipe 4 and liquid material efferent duct 5 at the two ends of piston cylinder 3 simultaneously.It is above-mentioned by a piston cylinder 3 that is provided with liquid material input pipe 4 and liquid material efferent duct 5 at two ends is set, in the time that needs add liquid material to reactor, by liquid material input pipe 4 from one end to the interior input liquid material of the cylinder chamber 1 of piston cylinder 3, promote piston body 2 and move to the other end, the liquid material being originally stored in cylinder chamber 1 is added to reactor from the liquid material efferent duct 5 of the other end.Because the volume of the cylinder chamber 1 of piston cylinder 3 is changeless, like this, just can directly measure by the volume of cylinder chamber 1 to the liquid material of adding in reactor at every turn, not need as existing proportioning valve, the volume of liquid material is obtained in passing ratio calculating indirectly.Thereby ensured each interpolation liquid material quantity accurately, guaranteed reaction fully, effectively and safety.
In above-mentioned embodiment, in order to simplify the structure of piston cylinder 3, reduce production costs, simultaneously, also in order to facilitate setting and the installation of liquid material input pipe 4 and liquid material efferent duct 5, the two ends of cylinder chamber 1 seal by end socket 6, and described liquid material input pipe 4 and liquid material efferent duct 5 are arranged on described end socket 6 respectively simultaneously; The liquid material input pipe 4 and the liquid material efferent duct 5 that on described each end socket 6, arrange all have the same transfer passage 7 being communicated with cylinder chamber 1, on each root liquid material input pipe 4 and liquid material efferent duct 5, are provided with stopper 8; The liquid material input pipe 4 connecting from the different ends of piston cylinder 3 respectively has same input port 9, the liquid material efferent duct 5 connecting from the different ends of piston cylinder 3 respectively has same delivery outlet 10, and stopper 8 is arranged on respectively on the liquid material efferent duct 5 on the liquid material input pipe 4 between transfer passage 7 and input port 9 and between transfer passage 7 and delivery outlet 10.In addition, liquid material input pipe 4 and liquid material efferent duct 5 with one end share a transfer passage 7, the liquid material input pipe 4 of different ends and liquid material efferent duct 5 share respectively an input port 9 and share a delivery outlet 10, can make automatic ration of the present invention add that the structure of device of liquid material is simplelyr gathered, occupation of land face is less, and then more convenient described device layout in process of production.
In above-mentioned embodiment, for the ease of the automatic control of described liquid material adding set, reduce operating personnel's labour intensity, the control that improves liquid material interpolation precision, described liquid material adding set also comprises permanent magnets 11 and electromagnetic induction detecting element 12, end socket 6 is permeability magnetic material end socket, permanent magnets 11 is arranged in piston body 2, and electromagnetic induction detecting element 12 is arranged on respectively the end of the cylinder chamber 1 at piston cylinder 3 two ends; Described stopper 8 adopts solenoid electric valve; Also comprise the automatic control system that contains PLC control module 13, the free end of solenoid electric valve and the control line of electromagnetic induction detecting element 12 is connected with PLC control module 13.Like this, when filling liquid material by liquid material input pipe 4 in the cylinder chamber 1 from one end to piston cylinder 3, when the other end is exported the whole liquid material in the former cylinder chamber 1 that is stored in piston cylinder 3 by liquid material efferent duct 5, permanent magnets 11 and electromagnetic induction detecting element 12 coordinate, to PLC control module 13 input signals, PLC control module 13 commands corresponding solenoid electric valve to open and close, and realizes and once adds liquid material.Then, as required by the reciprocal input of the difference end from piston cylinder 3 liquid material of above-mentioned process, output liquid material, and realized in reactor and added accurately liquid material.Certainly, described structure can be also, when filling liquid material by liquid material input pipe 4 in the cylinder chamber 1 from one end to piston cylinder 3, when the other end is exported the whole liquid material in the former cylinder chamber 1 that is stored in piston cylinder 3 by liquid material efferent duct 5, due to solenoid electric valve invention signal, open and close corresponding solenoid electric valve by manual operation, the automaticity that is this structure is relatively low, labour intensity is relatively large, and production efficiency is just not high yet.
Add the structure of the device of liquid material for the ease of understanding automatic ration of the present invention, now the operation principle of described device is done to one and simply say, and respectively each solenoid electric valve is numbered, each numbering refers to accompanying drawing 1.
On the liquid material input pipe 4 being connected with piston cylinder 3, be furnished with respectively normally closed solenoid electric valve L1, L4, on liquid material efferent duct 5, be furnished with normally closed solenoid electric valve L2, L3.When L1, L3 solenoid electric valve obtain when electric, solenoid electric valve is connected, and liquid material enters from left end through L1 solenoid electric valve the cylinder chamber 1 of piston cylinder 3, promotes piston body 2 toward moving right, thereby the liquid material being originally stored in cylinder chamber 1 is discharged through L3 solenoid electric valve; In the time that piston body 2 moves to right-hand member, permanent magnets 11 and electromagnetic induction detecting element 12 coordinate the position that detects piston body 2, and by the approach switch in PLC control module opening control, that is, magnetic valve L1, L3 dead electricity are closed, L2, L4 obtain electric connection, like this, liquid material enters from right-hand member through L4 solenoid electric valve again the cylinder chamber 1 of piston cylinder 3, promotes piston body 2 and moves to left, thereby discharge through L2 solenoid electric valve real the liquid in cylinder chamber.In the time that piston body 2 moves to left end, permanent magnets 11 and electromagnetic induction detecting element 12 coordinate again the position that detects piston body 2, and by the approach switch in PLC control module opening control,, magnetic valve L2, L4 dead electricity are closed, and L1, L3 obtain electric connection, and so forth.Owing to there being permanent magnets 11 in piston body 2, end socket 6 is made for permeability magnetic material, thus piston body 2 start bits always in one end of the cylinder chamber 1 of piston cylinder 3, thereby what make that piston cylinder 3 each stroke discharge is the liquid material of a cylinder chamber 1.
In sum, adopting the automatic ration of structure of the present invention to add the device of liquid material can carry out constant volume to the volume of added liquid material and directly measure; The volume accuracy of the liquid material adding, by designed cavity volume precision control, is not subject to transfer pipeline pressure, flow restriction, and precision stability is good; And simple in structure, Yi Hang, good economy performance.
