Embodiment
Below in conjunction with accompanying drawing, the utility model filter core special drying tunnel thermal temperature control system is described in further detail.
As shown in Fig. 3 ~ Fig. 6, the utility model filter core special drying tunnel thermal temperature control system, three-phase blower motor main circuit 401, three-phase primary power connects U1 three phase converter by QF7 three-phase breaker, exports variable-frequency power sources to load M4 blower motor, when frequency converter STF and SD holds through KA1, after KA8 relay is connected, frequency converter is in rotating forward state and runs, simultaneously can electrodeless adjustment rotation speed of fan, exports different air quantity (wind-force).
Air volume signal flip flop equipment loop 402, start SB5 blower fan button, KA8 relay obtains electric, blower fan rotates air inducing, produces powerful air-flow and enters in drying tunnel by air channel, after heating tube electrified regulation, heat of high temperature is delivered to drying tunnel, thermal treatment is cured to product and prepares.
In order to prevent the too small or fan trouble of air quantity from causing calm heating, (see Fig. 1 and Fig. 2) first opens one and to leak out mouth on air channel 1, air door box 3 air inlet 2 aim at leak out in air channel 1 tight-lipped tight identical.When wind is blown into air channel 1 by blower fan, sub-fraction in airflow enters air door box 3 from air inlet 2, originally the sagging aluminium matter air door panel 5 be overlapped on locating piece 6 is upwards blown afloat, after the sensor-triggered bar 7 be now connected on air door dwang 4 rotates 0 degree ~ 90 degree (different air quantity rotates different angles), trigger air volume signal sensor 8, at this moment represent that blower fan normally works, air quantity reaches setting requirement, now sensor SQ5 (air door is spacing) sends control signal (the air quantity triggering stop means position-adjustable that can heat, spread out of different air volume signal).In drying tunnel heating process, air quantity is not produced or air quantity is little as blower fan non rotating and blower fan are out of order, do not reach setting value, do not meet Product Process requirement, the then spacing SQ5 of air door not triggering and conducting, heating tube no power heats, stop in heating cabinet, heating tube only heats the hidden danger not having heat (hot blast) to draw, avoid product quality influenced, and heating cabinet after the heating prominent meet fault after, the too high electrical equipment that burns out of Yin Wendu causes equipment breakdown, thus ensures that production equipment two does not miss.
Blower motor overload flow control loop 403, after blower fan normally works and air quantity reaches setting value, through the adhesive of KT2 time relay time delay KA9 relay, seals in heating work control loop.At this moment blower fan U2 frequency converter failure relay is connected with the heat dropout contact of QF7 blower break device, and common composition blower fan overload flow control loop, makes heating cabinet when blower fan abnormal failure, disconnect rapidly heating circuit and stop heating, ensure device security.
Drying tunnel temperature control loop 404, in the adhesive of heating starting KA8 relay, 2 heating temperature control instrument enter temperature control status, and BT1 temperature controller controls working temperature in heating cabinet, and BT2 temperature controller controls working temperature in drying tunnel.When heating cabinet and any one actual temperature of drying tunnel are lower than temperature controller setting value, KA11, KA12 relay and the adhesive of KA10 relay, heating tube energising heats up, when actual temperature is higher than temperature controller setting value, and KA11, KA12 relay and the release of KA10 relay, heating tube power-off is lowered the temperature.Constantly so repeatedly make temperature in drying tunnel remain at setting range, be in constant temperature duty.
Drying tunnel temperature measure loop 405, according to product technology technique needs, higher to the temperature requirement in drying tunnel, except BT1, BT2 thermometer also increases BT3 outside controlling, and BT4 temperature controller is measured, like this many places multi-point monitoring is carried out to drying tunnel, form closed loop open loop, guarantee that drying tunnel temperature is evenly accurate.
Drying tunnel temperature alarm circuit 406, when drying tunnel internal temperature is abnormal, in BT1-4 temperature controller, any one overtemperature alarm output point sends signal, the just adhesive of KA15 relay, heating work loop cuts off rapidly by normally closed contact, KA10 relay, KM1 and KM2 solid-state relay dead electricity is in not on-state, and heating tube power-off stops heating.
Heat radiation and temperature are transmitted control circuit and have been carried out emphasis change to drying tunnel blower unit and attemperating unit and set up defenses in depth.In fan operation electrical control, adopt air volume signal and overload signal and the triple controlling unit of over-current signal, make blower fan operate in safe and reliable state all the time.Run in electrical control in heating adopts temperature to control and temperature detection and the another triple controlling unit of temperature alarming simultaneously, makes drying tunnel temperature remain stable temperature constant state, improve production efficiency and product quality.
The utility model filter core special drying tunnel thermal temperature control system ensures that filter core drying tunnel heats up rapidly, and homogeneous temperature, enhances productivity; Utilize air quantity flow rate signal to control, heat radiation transmission is played a positive role; By overload and overcurrent protection chain, make blower fan air inducing and heating temperature control two function close coordination greatly, safe and reliable; Adopt drying tunnel temperature multi-point monitoring, accurately control, product quality significantly improves; Equipment is normally run, reduces failure rate and manufacturing cost, serve remarkable result.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
