Description
Technical field
The utility model belongs to the fibre technical field of drying, is specifically related to a kind of degree of drying automaton of fibre dry kiln.
Background technology
The refractory fibre product of wet production contains a large amount of moisture and organic and inorganic bonding agent, need be through heat drying, curing and typing.What fibre dry kiln in the market adopted is electrical heating directly-heated type dry kiln or hot air type dry kiln.
Electrical heating directly-heated type dry kiln be with heating be arranged in the two sides of dry kiln inside/or three face walls on, by heat radiation heating and dried fibres goods that heating energising back heating is produced, the wet-emitting blower that the damp-heat that the dry run water evaporates produces is installed by dry kiln directly is discharged in the atmosphere.
The hot air type dry kiln is the hot blast that electricity consumption heat hot wind furnace or fuel gas hot-blast stove produce, and introduces heat drying fibre in the dry kiln by blower fan, and the wet-emitting blower that the damp-heat that the dry run water evaporates produces is installed by dry kiln directly is discharged in the atmosphere.
Adopt electrical heating directly-heated type dry kiln and hot air type dry kiln dried fibres goods, two kinds of methods arranged at the degree of drying of judging fibre:
The firstth, open the wicket taking-up and knock the degree of drying that listening is judged fibre by rule of thumb;
The secondth, open wicket and take out several checks of weighing, repeat to do the random sample check of weighing every certain hour again, weight reduces to be needed to continue dry, and constant promptly being judged to be of weight finished drying.
There are the following problems for the method for these two kinds of definite fibre dryings:
First method judges that the experience of fiber product drying needs long-term accumulation, and only suitable to the product of single specifications and models, just can't judge to have only second kind of decision method of employing for a plurality of specifications and models are dry simultaneously; Moreover there is bigger judgement difference again in different operators.This has increased the uncertainty of fibre dry run and the uncontrollability of fibre degree of drying undoubtedly, influences the fibre quality; The 3rd, judge that the process need of degree of drying is opened wicket repeatedly, the interior heat of kiln is scattered and disappeared, can cause energy resource consumption to increase.
Second method, control fibre degree of drying is more accurate, but when opening wicket sampling setting-out at every turn, all will turn off heater and stop heating, allows the manipulable feel degree of the corresponding people of dropping to of kiln temperature just can weighing; Repeatable operation all needs shutdown start to lower the temperature and heats up like this, not only can cause energy resource consumption to increase, and prolong drying and production cycle, the increase production cost.
Summary of the invention
The purpose of this utility model provides a kind of degree of drying automaton of fibre dry kiln, make it can overcome the shortcoming that prior art exists, it is simple, convenient to reach the control of dry kiln fibre degree of drying, and energy consumption for drying reduces, the effect of constant product quality.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of degree of drying automaton of fibre dry kiln, be provided with in order to gather the digital hygrometer of moisture signal band probe, be provided with digital temperature meter in order to collecting temperature signal band probe; Frequency conversion wet-emitting blower, frequency conversion air draft blower fan are set; Be provided with heater in order to fibre is heated; Be provided for controlling the PLC controller of frequency conversion wet-emitting blower, frequency conversion air draft blower fan and heater work, the output signal of described digital hygrometer, digital temperature meter is connected with the PLC controller, described PLC controller is connected with frequency conversion wet-emitting blower, frequency conversion air draft blower fan, heater by frequency conversion wet-emitting blower switch, frequency conversion air draft fan switch, heater button respectively, constitutes the degree of drying automaton.
The degree of drying automaton of the fibre dry kiln that the utility model proposes has overcome the shortcoming that exists in the prior art, and it is simple, convenient to have reached the control of dry kiln fibre degree of drying, and energy consumption for drying reduces, the effect of constant product quality; Make the index of fibre dry kiln be: temperature difference in the dry kiln ± 3 ℃, humidity control range 70～5%, 30～120 ℃ of temperature controlling range.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, digital hygrometer, 2, probe, 3, moisture signal, 4, the PLC controller, 5, frequency conversion wet-emitting blower switch, 6, frequency conversion air draft fan switch, 7, heater button, 8, the frequency conversion wet-emitting blower, 9, frequency conversion air draft blower fan, 10, heater.
The specific embodiment
With specific embodiment the utility model is illustrated in conjunction with the accompanying drawings, below non-limiting embodiment be used for further describing the utility model, that mentions among the embodiment of being not limited to wherein described in the utility model is several.
As shown in Figure 1, a kind of degree of drying automaton of fibre dry kiln, be provided with in order to gather the digital hygrometer 1 of moisture signal band probe 2, be provided with digital temperature meter (not providing among the figure), frequency conversion wet-emitting blower 5, frequency conversion air draft blower fan 6 are set in order to collecting temperature signal band probe; Be provided with heater 7 in order to fibre is heated; Be provided for controlling the PLC controller 4 of frequency conversion wet-emitting blower 5, frequency conversion air draft blower fan 6 and heater 7 work, the output signal 3 of described digital hygrometer 1, digital temperature meter is connected with PLC controller 4, described PLC controller 4 is connected with frequency conversion wet-emitting blower 8, frequency conversion air draft blower fan 9, heater 10 by frequency conversion wet-emitting blower switch 5, frequency conversion air draft fan switch 6, heater button 7 respectively, constitutes the degree of drying automaton.
When dry, the probe 2 of digital hygrometer 1, the probe of digital temperature meter insert in the kiln, measure kiln atmosphere humidity, show on display; PLC controller 4 is gathered signal from digital hygrometer 1, digital temperature meter, calculates comparison; When humidity greater than when setting value, PLC controller 4 sends instruction to frequency conversion wet-emitting blower switch 5, frequency conversion wet-emitting blower frequency improves, faster rotational speed, exhaust air rate increases; When humidity less than when setting value, PLC controller 4 sends instruction to frequency conversion wet-emitting blower switch 5, frequency conversion wet-emitting blower 8 frequencies reduce, rotating speed reduces, exhaust air rate reduces; When humidity in the certain hour section all less than when setting value, PLC controller 4 is to heater button 7 issuing command signals, heater 10 quits work, and closes heater power source; And send instruction to frequency conversion wet-emitting blower switch 5, reduce frequency conversion wet-emitting blower 8 frequencies to setting value; When kiln temperature dropped to setting value, PLC controller 4 sent instruction to frequency conversion air draft fan switch 6, and frequency conversion air draft blower fan 9 quits work, and closes frequency conversion air draft fan switch power supply; Dry run is finished.
