The automatic switching control device greatly improves production efficiency of bear, lowers labor intensity and improves metering accuracy.
Description
Technical field
The utility model relates in beer production CO
2the control gear that gas supply flow meter automatically switches.
Background technique
Under nominal situation, CO
2about 30 DEG C of temperature, the CO of beer industry
2flowed fluctuation in air supply header is very large, owing to being subject to the restriction of flowmeter range, and often need to be at CO
2the flowmeter that is installed in parallel two or some different bores on gas manifold measures.The switching of flowmeter generally adopts manual control mode, in the time that changes in flow rate is frequent, needs staff on duty, and labor intensity is large and accuracy rate is low.More seriously, under sterilization operating mode, most of with gas branch pipe under nominal situation, and wherein one or a few crossed state with gas branch pipe in vapor stream.Sterilization rises to rapidly 100 DEG C by temperature in gas branch pipe pipeline, steam by by this with using throughput meter on gas branch pipe, steam is also by as CO
2metering, brings very large error to metering result.
Model utility content
In order to overcome under nominal situation, CO
2a kind of CO2 gas supply flow of the difficult Design of Problems switching of gas manifold flowmeter meter automatic switching control device.
The technological scheme adopting is as follows:
A kind of CO
2gas supply flow meter automatic switching control device, comprise PLC controller, kneel supply cut off valve, gas supply flow meter, uses throughput meter, some gas manifolds, some are provided with the kneel supply cut off valve corresponding with this gas manifold and gas supply flow meter successively with gas branch pipe on every gas manifold, every with corresponding with this use gas branch pipe throughput meter of using is installed on gas branch pipe, be transferred to PLC controller with the flux signal that throughput meter collects, PLC controller outputs a control signal to kneel supply cut off valve.
This device has improved the accuracy of manufacturing efficiency and metering, has reduced labor intensity.
In order to make this device not only be applicable to nominal situation but also be applicable to sterilization operating mode, at a temperature transmitter of the corresponding installation in each downstream with throughput meter, the transient temperature that PLC controller sends by temperature transmitter judges that this control system is in nominal situation or in sterilization operating mode.(in the time that temperature is less than 50 DEG C, judge that this control system is in nominal situation, in the time that temperature is more than or equal to 50 DEG C, judge that this control system is in sterilization operating mode).
When in sterilization operating mode, this temperature transmitter of PLC controller control corresponding with throughput meter in not measuring state.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment one:
Under nominal situation, a kind of CO
2gas supply flow meter automatic switching control device, comprise PLC controller 80, kneel supply cut off valve 21, kneel supply cut off valve 22, gas supply flow meter 31, gas supply flow meter 32, with throughput meter 61, with throughput meter 62, with throughput meter 63, with throughput meter 64, with throughput meter 65, gas manifold 11, gas manifold 12, with gas branch pipe 51, with gas branch pipe 52, with gas branch pipe 53, with gas branch pipe 54, with gas branch pipe 55, the kneel supply cut off valve corresponding with this gas manifold and gas supply flow meter are installed on every gas manifold successively, every corresponding with this use gas branch pipe with throughput meter 61 with being provided with successively on gas branch pipe, with throughput meter 62, with throughput meter 63, with throughput meter 64, with throughput meter 65, the instantaneous flow rate signal collecting is transferred to PLC controller 80 by they, PLC controller 80 is to throughput meter 61, with throughput meter 62, with throughput meter 63, with throughput meter 64, sue for peace with the instantaneous flow of throughput meter 65, switch gas supply flow meter according to summed result control kneel supply cut off valve, the range of gas supply flow meter 31 is less than the range of gas supply flow meter 32.Flow summed result hour PLC controller 80 control unlatching kneel supply cut off valves 21 is used gas supply flow meter 31, when flow summed result is larger, PLC controller 80 is controlled unlatching kneel supply cut off valve 22 and is used gas supply flow meter 32, when flow summed result is especially big, PLC controller 80 is controlled and is opened kneel supply cut off valve 21 and kneel supply cut off valve 22 simultaneously, and gas supply flow meter 31 and gas supply flow meter 32 use simultaneously.
Embodiment two:
Under sterilization operating mode, with throughput meter 61, with throughput meter 62, with throughput meter 63, with throughput meter 64, with corresponding temperature transmitter 71, temperature transmitter 72, temperature transmitter 73, temperature transmitter 74, the temperature transmitter 75 installed in downstream of throughput meter 65.
When to 55 sterilization of use gas branch pipe, valve 90 is closed, steam is full of with gas branch pipe 55, temperature transmitter 75 detects and is more than or equal to 50 degree by the interior temperature of gas branch pipe 55, temperature transmitter 75 transmits Temperature numerical signal to PLC controller 80,80 judgements of PLC controller are with gas branch pipe 55 in sterilization state, and PLC controller output control signal is given with throughput meter 65, makes flowmeter 65 in not measuring state.PLC controller is to throughput meter 61, with throughput meter 62, with throughput meter 63, sues for peace with the instantaneous flow of throughput meter 64, according to summed result control kneel supply cut off valve 21 and kneel supply cut off valve 22 choice for use gas supply flow meter 31 and gas supply flow meters 32.
The above, be only embodiment of the present utility model, and in the scope that those of ordinary skill in the art disclose at the utility model, the variation that can expect easily, within all should being encompassed in protection domain of the present utility model.
