The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model preferred embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1 and Fig. 2, a kind of biomass particle burning machine, comprise combustion-supporting air blast 1, pay-off 2, combustion chamber 3 and control device, described pay-off 2 comprises variable frequency drive motors 21, the screw rod 22 being connected with this variable frequency drive motors 21, and be arranged on screw rod 22 tops for filling the feed bin 23 of biological particles, described control device comprises gravity sensor 41, temperature sensor 42 and controller 43, described gravity sensor 41, temperature sensor 42 is all connected with described controller 43, described gravity sensor 41 is arranged on the CD outlet of described feed bin 23, described temperature sensor 42 is arranged on the end of described screw rod 22, the end of described screw rod 22 passes into combustion chamber 3, described controller 43 is connected with variable frequency drive motors 21, combustion-supporting air blast 1 respectively, and described combustion-supporting air blast 1 is connected by an air channel 5 with described combustion chamber 3, and described controller 43 is provided with sound-producing device 44, and described gravity sensor 41 is connected with this sound-producing device 44.
Wherein, described temperature sensor 42 is preferably the sensor that output signal is analog signal, and can certainly adopt output signal is the sensor of data signal, and this temperature sensor can be thermocouple or thermistor etc.
In general, variable frequency drive motors described in prior art 21 all can be provided with frequency converter 24, and preferably, described temperature sensor 42 regulates the output frequency of frequency converter 24 by output signal.Such adjusting is more accurate sooner.Thereby the frequency of frequency converter 24 is controlled by temperature sensor 42, thereby made temperature sensor control variable frequency drive motors by controller, further control the charging rate of the screw rod being connected with variable frequency drive motors.
Equally, described gravity sensor 41 is preferably the sensor that output signal is analog signal, and can certainly adopt output signal is the sensor of data signal.
Described sound-producing device 44 is preferably interconnective loudspeaker (not shown) and red led (not shown).Can certainly be loudspeaker, and not establish indicator lamp or with the indicator lamp of other colors.The effect of this sound-producing device 44 has been mainly prompting function.
Certainly, this combustor also comprises igniter 6, and the ignition trigger process of this combustor is: open pay-off 2 and control device, pay-off 2 starts feeding, stops feeding (now existing fuel in combustion chamber) after approximately 3 minutes; Igniter is started working, and stops igniting after lighting a fire successfully, and the biomass granule fuel in combustion chamber 3 takes fire; Pay-off 2 restarts work, and combustion-supporting air blast work now completes the process of biomass particle burning machine from starting to working.
Then, because combustor is provided with the temperature sensor with analog output signal function, temperature sensor is connected with variable frequency drive motors, combustion-supporting air blast by controller.Temperature sensor can detect burning built-in temperature, and controller is controlled above-mentioned variable frequency drive motors, combustion-supporting air blast according to this.
Therefore, the control device course of work of this combustor is as follows:
First, should be appreciated that biological combustor combustion chamber fuel is many, calory burning is large, otherwise combustion fuel is few, and the heat of generation is also little.
On the one hand, biomass granule fuel completes toward combustion chamber feeding by screw rod work, and the speed of screw rod is by the Frequency Converter Control being connected with screw rod, and the frequency of frequency converter is controlled by controller by temperature sensor.So the temperature in combustion chamber and screw rod feeding are connected, by the output signal of temperature sensor, regulate the output frequency (exporting and peak frequency is exported by actual set minimum frequency) of frequency converter.When burning indoor actual temperature is during lower than design temperature, temperature sensor outputting analog signal is large, and the frequency converter frequency being connected with screw rod is high, and feeding is fast; When burning indoor actual temperature reaches design temperature soon, temperature sensor outputting analog signal is little, and frequency converter frequency is low, and feeding is slow.When burning indoor actual temperature (can arrange according to actual conditions the preset value of this temperature during higher than a preset value of design temperature, as 4 degree or 5 degree), temperature sensor is controlled combustion-supporting air blast and is quit work, flame combustion chamber will reduce, the heat producing also will diminish, and burning indoor temperature will reduce very soon; On the contrary, when burning indoor actual temperature is during lower than design temperature, combustion-supporting air blast will be opened automatically, and flame combustion chamber will become greatly, and the heat of generation also will become greatly, need only assurance fuel enough, and the temperature in combustion chamber will raise; So go round and begin again, within guaranteeing that temperature in combustion chamber remains on certain scope.
And on the other hand, enough in order to guarantee fuel, the gravity sensor arranging at material outlet, according to the variation of biomass granule fuel gravity, exports this variable signal to controller, by the sound-producing device of controller, remind.When biomass granule fuel gravity is less than a certain setting value, the loudspeaker of sound-producing device sound, and red led lights, and remind workman to carry out toward the reinforced operation of feed bin, the stability that keeps feed bin work, within the temperature in further assurance combustion chamber remains on certain scope simultaneously.
After having worked, the temperature-fall period of this combustor is as follows: close combustion-supporting air blast and control device, close material outlet (can establish a baffle plate realizes), fuel is no longer continued toward screw rod feeding.Screw rod stops (fuel of screw rod all being delivered in combustion chamber guaranteeing) after working on 3 minutes, close and drive variable-frequency motor (stopping screw rod work), thereby complete the process of cooling after combustion chamber is completely cooling.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
