Description
The utility model relates to a kind of fluid media (medium) that is applicable to, is particularly useful for the electronic batch adjusting apparatus of fluid media (medium) of the batch metering of styrene-butadiene latex in the chemical industry.
The batch metering of fluid media (medium) is widely used in the production practices of oil, chemical industry, metallurgy, medicine.A kind of electronic batch adjusting apparatus that is used for the batch metering of chemical industry styrene-butadiene latex is arranged in the market, and it comprises liquid material measuring tank, ellipse garden gear meter adjusting apparatus and the pneumatic O type of electromagnetic conversion valve.Known technology has its shortcoming, promptly when styrene-butadiene latex is flowed through ellipse garden gear meter, causes breakdown of emulsion owing to latex between gear and the axle is squeezed and rubs.When this breakdown of emulsion reached some, the micelle that is bonded on the gear shaft will " asphyxia by external pressure on the chest and abdomen ", causes gear shaft to stop operating, thereby forces electronic batch adjusting apparatus to quit work.
The purpose of this utility model is to propose a kind of new mechanism to replace ellipse garden flowmeter and adjusting apparatus in the known technology, avoids breakdown of emulsion, overcomes the shortcoming of known technology.
Another purpose of the present utility model is to reduce the fluid media (medium) cost of gauging instrument in batches.
The purpose of this utility model reaches by taking following measure.It comprises the liquid material measuring tank, the pneumatic O type of electromagnetic conversion stop valve, electronic transmitter, electronic III type safety barrier, FC series instrument divider, 24 volts of relays of PMK single-loop regulator able to programme and direct current, be that flange is connected between liquid material measuring tank and the electronic transmitter wherein, electronic transmitter, electronic III type safety barrier, FC series instrument divider, PMK single-loop regulator able to programme, be followed successively by circuit between 24 volts of relays of direct current and the moving O type stop valve of electromagnetism brick ventilation and connect, the pneumatic O type of electromagnetic conversion stop valve is installed on the output pipe of liquid material measuring tank.
The purpose of this utility model can also take following measure to reach.Described electronic transmitter is an electronic liquid level transmitter; Electronic III type safety barrier is a PWZB10AI safety barrier; FC series instrument divider is a PXMGYYY2-0 FC series instrument divider; PMK single-loop regulator able to programme is a PMKBACW2-00 single-loop regulator able to programme; 24 volts of relays of direct current are 24 volts of sensitive relays of a direct current; The pneumatic O type of electromagnetic conversion stop valve is made up of single two the intercommunication solenoid valves of electricity of a K25D-10B and the pneumatic O type of a ZSHO-64 stop valve.
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is a connection layout of the present utility model;
Fig. 3 is the connection layout of PMK programming single-loop regulator 5.
Further specify how to realize the utility model below in conjunction with accompanying drawing.
Fig. 1 is a schematic diagram of the present utility model.Principle as can be seen from Figure 1 of the present utility model.
Fig. 2 is a connection layout of the present utility model.The effect of liquid material measuring tank 1 is to hold fluid media (medium), and its geometric figure is the garden cylindricality preferably.Electronic transmitter 2 is installed in fluid state material metering groove 1 bottom, and its effect is the volume of the fluid media (medium) in the liquid material measuring tank 1 or quality to be transformed into current signal transfer out.Can adopt stream interface transmitter, pressure unit or differential pressure transmitter.Electronic III type safety barrier 3 plays current limiting pressure-limiting in control loop, explosive area and place of safety are separated, and constitutes the Sefe antiexplosion control loop.FC series instrument divider 4 is transformed into voltage signal with the current signal of electronic transmitter 2 inputs, with the coupling of realization with PMK single telegram in reply able to programme road regulator 5, so long as the instrument divider of FC series all can adopt.The effect of PMK single telegram in reply able to programme road regulator 5 is that the given measured value of the measured value that will represent from the voltage signal of FC series instrument divider 4 input and this machine compares, computing.Export an electric signal when measured value during greater than this definite value the pneumatic O type of electromagnetic conversion stop valve 7 is opened, the beginning charging when measured value equals setting value, is exported an electric signal again, and the pneumatic O type of electromagnetic conversion stop valve 7 cuts out, and regulates in batches thereby finish once.The difference of setting value and measured value is inlet amount.The effect of 24 volts of relays 6 of direct current is to improve the instrument carrying load ability, controls closing and opening of the pneumatic O type of electromagnetic conversion stop valve 7 with the contact of relay.The pneumatic O type of electromagnetic conversion stop valve 7 is installed on the output pipe of liquid material measuring tank 1.
Fig. 3 is the circuit connection diagram of PMK of the present utility model single-loop regulator 5 able to programme.From figure, can be clear that very much its connected mode.8,9 is load module, and 10,11,12,13 are control, computing module, and 14,15 is output module.
Compare with known technology, electric dosage adjuster for liquid media of the present utility model has following advantage:
1, reliability standard height. Owing to the ellipse garden gear meter that new mechanism has replaced known technology, avoided the generation of demulsifying phenomenon. Through test running, accident did not take place.
2, measuring accuracy height. Can reach below 0.5%, can satisfy the technological requirement of the industries such as oil, chemical industry, metallurgy and medicine fully.
3, cost is low. Like product low about 50% than known technology.
