Utility model content
Technical problem to be solved in the utility model is to overcome prior art defect, provides a kind of maintenance that can reduce the loss of finished product gas to regenerate the constant exsiccator control module of air rate.
In order to solve the problems of the technologies described above, the exsiccator control module that the maintenance regeneration air rate that the utility model provides is constant, comprise air flowmeter, pressure transducer, stepper motor driving circuit, microprocessor, storer and power supply, described air flowmeter and pressure transducer are arranged on exsiccator air intake opening, described air flowmeter, pressure transducer, stepper motor driving circuit are all connected with processor with storage unit, and power supply is that whole control module is powered.
In the utility model, described power supply exports direct current 5V and direct current 24V respectively; Described direct current 5V is used for powering to microprocessor, stepper motor driving circuit and storer; Direct current 24V is used for the power supply to air flowmeter and pressure transducer.
In the utility model, described storer is E2PROM.
The beneficial effects of the utility model are: the utility model detects the flow of exsiccator air intake opening gas in real time by air flowmeter and pressure transducer, pressure size feeds back to microprocessor, microprocessor is according to the size determining the regeneration throttle orifice required when air rate setting value, send signal to adjust regeneration throttle orifice by stepper motor driving circuit control step motor forward or reverse and become large or diminish, regulate regeneration air consumption, thus keep regeneration air rate constant, reduce compressed-air actuated loss.
Accompanying drawing explanation
Fig. 1 is the structural representation of the exsiccator control module that the utility model keeps regeneration air rate constant.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the exsiccator control module that the utility model keeps regeneration air rate constant, comprises air flowmeter and pressure transducer, stepper motor driving circuit, microprocessor, storer and power supply; Air flowmeter is all connected with microprocessor with storer with pressure transducer, stepper motor driving circuit.
Power supply is that whole control module is powered, and power supply exports direct current 5V and direct current 24 respectively, and wherein direct current 5V is used for powering to microprocessor, stepper motor driving circuit and storer, and direct current 24V is used for the power supply to air flowmeter and pressure transducer.
Air flowmeter, pressure transducer are arranged on the air intake opening place of exsiccator, for detecting exsiccator inlet air flow and pressure and feeding data back to microprocessor.
Stepper motor driving circuit receives the signal from microprocessor and performs, and the forward or reverse of control step motor realizes the adjustment regenerating hole size.
Storer terminates the size in rear regeneration hole for storing adjustment, with the comparison be convenient to next time; Storer adopts E2PROM, and its speed is fast, and good stability, data can not be lost after a power failure.
After microprocessor is mainly used in admission of air flow and pressure sensor data, calculate when air rate is constant according to flow and pressure gauge, the size in required regeneration hole, send and control signal to stepper motor driving circuit execution.
Specific works process of the present utility model is: the pressure detected in real time and data on flows are passed to microprocessor by the flowmeter and the pressure transducer that are arranged on exsiccator air intake opening, after microprocessor receives data, calculate when air rate is constant according to flow and pressure gauge, the size in required regeneration hole, send and control signal to stepper motor driving circuit, stepper motor driving circuit receives control step motor positive and inverse after the signal from microprocessor, working time adjusts regeneration hole size, storer then stores the size that this adjustment terminates rear regeneration hole.
When needs adjust regeneration hole size again, microprocessor first reads the size in regeneration hole at present in storer, the flow detected according to flowmeter and pressure transducer again and pressure go the size calculating regeneration hole, then two regeneration hole sizes are compared, determine that regeneration hole increases or reduces, and then determine the rotating of Driving Stepping Motor and the time of required rotation that regulate regeneration hole size, the regeneration hole value simultaneously this calculated is stored in storer.Microprocessor, by driving circuit Driving Stepping Motor, makes stepper motor run the regular hour, and the size in adjustment regeneration hole, keeps the constant of regeneration air rate thus.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection domain of the present utility model.
