Description
Technical field
The present invention relates to a kind of drier controlling organization, is especially a kind of drier control for keeping regeneration air rate constant
Unit processed, belongs to drying device field.
Background technology
System of non heated regeneration dryer is to use principle of pressure swing adsorption, and compressed air is dried using heatless regeneration method
A kind of equipment.System of non heated regeneration dryer device is simple to operate with its, the advantages that reliable operation, obtains widely should in every profession and trade
With.But existing heatless regeneration drying can not ensure that regeneration air rate is constant in regeneration, cause the loss of a large amount of compressed airs,
Increase drier operation expenditure and the wasting of resources.
The content of the invention
The technical problems to be solved by the invention are to overcome prior art defect, there is provided a kind of damage that can reduce finished product gas
The holding of consumption regenerates the constant drier control unit of air rate.
In order to solve the above-mentioned technical problem, the drier control unit provided by the invention for keeping regeneration air rate constant,
Including mass air flow sensor, pressure sensor, stepper motor driving circuit, microprocessor, memory and power supply, the air
Flowmeter and pressure sensor are arranged on drier air inlet, the mass air flow sensor, pressure sensor, driving stepper motor electricity
Road and memory cell are connected with processor, and power supply is powered for whole control unit.
In the present invention, the power supply exports direct current 5V and direct current 24V respectively；The direct current 5V is used for microprocessor
Device, stepper motor driving circuit and memory power supply；Direct current 24V is used for the power supply to mass air flow sensor and pressure sensor.
In the present invention, the memory is E2PROM.
The beneficial effects of the present invention are：The present invention detects drier by mass air flow sensor and pressure sensor and entered in real time
The flow of gas port gas, pressure size feed back to microprocessor, and microprocessor is required in air rate setting value according to determining
Regeneration throttle orifice size, send signal and control stepper motor forward or reverse to adjust again by stepper motor driving circuit
Tight knot discharge orifice becomes big or diminished, regulation regeneration air consumption, constant so as to keep regenerating air rate, reduces the loss of compressed air.
Brief description of the drawings
Fig. 1 is the structural representation that the present invention keeps regenerating the constant drier control unit of air rate.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention keeps the constant drier control unit of regeneration air rate, including mass air flow sensor and pressure
Force snesor, stepper motor driving circuit, microprocessor, memory and power supply；Mass air flow sensor and pressure sensor, step
Stepper motor drive circuit and memory are connected with microprocessor.
Power supply is powered for whole control unit, and power supply exports direct current 5V and direct current 24, wherein direct current 5V respectively
For being powered to microprocessor, stepper motor driving circuit and memory, direct current 24V is used for mass air flow sensor and pressure sensing
The power supply of device.
Mass air flow sensor, pressure sensor are arranged at the air inlet of drier, for detecting drier inlet air
Flow and pressure simultaneously feed data back to microprocessor.
Stepper motor driving circuit receives the signal from microprocessor and execution, controls the forward or reverse of stepper motor
To realize the regulation of regeneration hole size.
Memory is used to store the size for regenerating hole after adjustment terminates, with being easy to comparison next time；Memory uses
E2PROM, its speed is fast, and stability is good, and data will not lose after a power failure.
Microprocessor is mainly used in after receiving air mass flow and pressure sensor data, is calculated according to flow and pressure gauge
In the case that air rate is constant, the size in required regeneration hole, sends control signal to stepper motor driving circuit and perform.
The present invention specific work process be：The flowmeter and pressure sensor for being arranged on drier air inlet will be examined in real time
The pressure and data on flows measured is transmitted to microprocessor, after microprocessor receives data, is calculated according to flow and pressure gauge
In the case that air rate is constant, the size in required regeneration hole, control signal is sent to stepper motor driving circuit, stepping electricity
Drive circuit controls stepper motor rotating, run time to carry out regeneration hole size after receiving the signal from microprocessor
Adjustment, memory then store the size that hole is regenerated after this adjustment terminates.
When needing to adjust regeneration hole size again, microprocessor first reads the size for regenerating hole in memory at present, then
The flow and pressure detected according to flowmeter and pressure sensor goes to calculate the size in regeneration hole, then that two regeneration holes are big
It is small to be compared, it is determined that regeneration hole is increase or reduction, and then determine the Driving Stepping Motor of regulation regeneration hole size just
Reversion and the time of required rotation, while the regeneration hole value that this is calculated is stored into memory.Microprocessor passes through
Drive circuit Driving Stepping Motor, stepper motor is run the regular hour, the size in adjustment regeneration hole, thus keep regeneration consumption
Gas rate it is constant.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
