Abstract
Disclosed is an airflow dryer, which comprises a drying tube; one end of the drying tube is connected with a radiator through a wind pipe and the other end is connected with a cyclone separator which is provided with a discharging packing auger at the lower end; the cyclone separator is connected with an off-gas pipe through a redirector and the off-gas pipe is connected with an exhaust tube; a feeder and a motor which is provided with a transducer are arranged at the lower end of the wind pipe; a blower and a PLC controller which is provided with a touch screen are arranged at the lower end of the off-gas pipe; a regulator valve connected with the PLC controller is arranged at the gas inlet of the radiator, and a thermometer connected with the PLC controller is arranged at the gas outlet of the radiator; a second thermometer connected with the PLC controller is arranged at the off-gas pipe; the transducer of the motor is connected with the PLC controller.
Description
Technical field:
The utility model relates to a kind of drying equipment, especially a kind of pneumatic drier.
Background technology:
In the prior art, when technique known is pneumatic conveying dryer adjusting EAT and inlet amount, all be manual adjustments, can not control the content of moisture in the material timely, and complex operation, this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model, be exactly at the existing in prior technology deficiency, and a kind of technical scheme of pneumatic drier is provided, this scheme is by the temperature of measurement air intake and the temperature of tail gas, control inlet amount and EAT timely, guaranteed the water content in the material within the limits prescribed.
This programme is realized by following technical measures: pneumatic drier, include drying tube, one end of drying tube is connected with radiator by airduct, the other end links to each other with cyclone separator, there is the discharging auger lower end of cyclone separator, cyclone separator is connected with offgas duct by steering gear, offgas duct is connected with tail gas discharging pipe, the motor that feeding machine and band frequency converter are arranged in the airduct lower end, in the offgas duct lower end blower fan is arranged, the concrete characteristics of this programme also have: the PLC controller that has touch-screen, the control valve that links to each other with the PLC controller is arranged at the radiator air inlet, there is the thermometer that links to each other with the PLC controller gas outlet of radiator, at the offgas duct place thermometer that links to each other with the PLC controller is arranged, the frequency converter of described motor links to each other with the PLC controller.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because pneumatic drier includes the PLC controller that has touch-screen in this scheme, the control valve that links to each other with the PLC controller is arranged at the radiator air inlet, there is the thermometer that links to each other with the PLC controller gas outlet of radiator, this thermometer and control valve and PLC controller constitute close loop control circuit, control to adjust valve by the PLC controller, regulate wind-warm syndrome, the temperature feedback is provided for the PLC controller at the thermometer at offgas duct place, according to the temperature of feedback, the PLC controller can further be regulated EAT; The frequency converter of motor links to each other with the PLC controller and constitutes the open loop control loop, regulates feeding packing auger by adjusting frequency converter, reaches the purpose of control inlet amount.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1 is the PLC controller, and 2 is control valve, 3 is radiator, and 4 is that thermometer 1,5 is a feeding machine, 6 is frequency converter, and 7 is motor, and 8 is airduct, 9 is drying tube, and 10 is cyclone separator, and 11 are steering gear, 12 are the discharging auger, and 13 is offgas duct, and 14 is tail gas discharging pipe, 15 is that thermometer 2,16 is a blower fan.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the pneumatic drier of this programme, include drying tube (9), one end of drying tube (9) is connected with radiator (3) by airduct (8), the other end links to each other with cyclone separator (10), there is discharging auger (12) lower end of cyclone separator (10), cyclone separator (10) is connected with offgas duct (13) by steering gear (11), offgas duct (13) is connected with tail gas discharging pipe (14), the motor (7) that feeding machine (5) and band frequency converter (6) are arranged in airduct (8) lower end, in offgas duct (13) lower end blower fan (16) is arranged, the PLC controller (1) that has touch-screen in addition, the control valve (2) that links to each other with PLC controller (1) is arranged at radiator (3) air inlet, there is the thermometer 1 (4) that links to each other with PLC controller (1) gas outlet of radiator (3), locate the thermometer 2 (15) that links to each other with PLC controller (1) in offgas duct (13), the frequency converter (6) of motor (7) links to each other with PLC controller (1).
