The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Fig. 1 is the structural representation of the pulper of use pulping process of the present invention, and pulper includes head 1, motor 2, control circuit, anti-overflow device 3, cup body 4, electric machine rotational axis 5, reducing mechanism 6, heater 7, temperature sensing device 8 and anti-dry burning device 9.In the present embodiment, motor 2, control circuit and control panel etc. are arranged in the head 1, anti-overflow device 3 adopts the anti-overflow probe, reducing mechanism 6 is mounted in the double blade Disintegrating knife on the electric machine rotational axis 5, heater 7 is mounted in the heat-generating pipe under the head 1, anti-dry burning device 9 is for stretching into the anti-dry probe in glass body, temperature sensing device 8 is to add thermistor in the anti-dry probe, monitor the temperature of slurries with resistance, be provided with in the cup 4 as any disturbing flow devices such as guard, flow-disturbing muscle.
Fig. 2 is the program flow diagram of pulping process of the present invention, and concrete pulping process is as follows:
After putting into an amount of pulping materials and water in the mash vessel and selecting suitable menu, press the start key on the control panel.
Water level detecting:
The water level detecting function is used to prevent that pulper from working under improper situation, thereby can avoid the generation of security incident.And sensed water level is from start to finish, i.e. pulper sensed water level always under the "on" position in case detect anhydrously, will start warning immediately, and quit work, locked button.
The pulping materials warm-up phase:
Pulping materials defibrination shredding stage:
Step a, after warm-up phase was finished, pulper began the mixture of pulping materials and water is carried out the defibrination pulverizing.Motor 2 drives 6 pairs of pulping materials of reducing mechanism and pulverizes, it is that the circulation pulping process is switched in rotating that motor 2 drives reducing mechanism 6 crushing process, its flow process is as shown in Figure 3: motor earlier just/counter-rotating M S, dwell time X S then, anti-again/as just to change N S, dwell time Y S then, this process circulation Z time.Test of many times proves, when satisfying following parameter and be provided with, the effect of its making beating is best: 1s≤M≤10s, 1s≤N≤10s, 0.1s≤X≤5s, 0.1s≤Y≤5s, 1≤Z≤10, the total time scope that the circulation pulping process is switched in above rotating is controlled at 10s≤t1≤60s.
After motor 2 drive reducing mechanisms 6 have been pulverized pulping materials, dwell time t2, the purpose that stops t2 mainly is in order to strengthen crushing effect, test of many times proves, rotating is switched the circulation pulping process after whipping a period of time, its crushing effect obviously descends, and at this moment motor must shut down, and then restarts and carry out the rotating whipping, but dwell time t2 is unsuitable long, general 5s≤t2≤20s, this step a circulation n1 time, 1≤n1≤5.
Step b can also insert the heating of short time at the defibrination shredding stage, its objective is in order to make whole shredding stage be in certain temperature environment and carries out, and is convenient to the further softening of beans material, makes the easier pulverizing of beans material.Slurries stop t3 after being heated to and running into anti-flow electrode, in order to strengthen the anti-overflow effect, general 10s≤t3≤30s.Whole pulping materials defibrination shredding stage comprises step a and step b, and circulation n2 time, general 3≤n2≤12.
The infusion stage of pulping materials:
After pulping materials was pulverized fully, pulper began slurries are carried out the high temperature heating, touches anti-flow electrode until slurries.It mainly is in order to reduce the power of electro-heat equipment that electro-heat equipment adopts the mode of intermittently heating, because in heating process, have a large amount of foams in the slurries, if employing heating with full power, stop the heating back because the electro-heat equipment waste heat is bigger, after slurries touched anti-flow electrode, foam also can continue along with the release of waste heat to rise, thereby overflow cup, stay certain potential safety hazard.
Slurries stop t4 after touching anti-flow electrode, mainly are slurries are fallen after rise, and this time is distinguished to some extent according to the difference of beans material.As wet beans stop heat time heating time, to grow with respect to dried beans, in general 10s≤t4≤40s.Whole slurrying infusion step cycle n3 time, n3 is relevant with factors such as beans material, water levels, general 5≤n3≤20.
After the circulation heating froth breaking stage finished, slurrying finished, and system withdraws from, and warning device sends the signal that slurrying finishes.
The pulping process of pulper of the present invention also is set with time t0, and when picking up counting t0 from system, whether not control is finished program, and pulping program finishes, and system withdraws from, and warning device sends the signal that slurrying finishes.In the present embodiment, t0=35 minute.
Fig. 5 is the circuit controling drawing that the present invention realizes motor positive and inverse in the pulping process, mainly include control module MCU, zero cross detection circuit 10, SCR control module 12, motor 2 and be series excited machine, rectification module 11, reducing mechanism 6 are directly driven by series excited machine.Control module MCU is connected with SCR control module 12, SCR control module 12 is connected in series with series excited machine and rectification module 11, control module MCU is by controlling the work of entire circuit to the detection of zero cross detection circuit 10 signals, wherein rectification module 11 is a rectifier bridge, series excited machine armature M is connected to the rectifier bridge dc output end, and Exciting Windings for Transverse Differential Protection is serially connected in outside the rectifier bridge.
Zero passage detection 10 circuit as shown in Figure 4, in conjunction with Fig. 5, the control circuit operation principle is as follows: zero cross detection circuit 10 adopts isolating transformer T, D5-T, D6-T is that AC signal changes with the civil power of importing, control module MCU is by the signal of I01, when know zero passage, control module MCUI/O exports a high level signal, drive controllable silicon T1 conducting, series excited machine and rectification module thereof 11 electric after, this moment armature M sense of current Exciting Windings for Transverse Differential Protection direction unanimity, motor begins just to change, when M time second then, control module MCU exports a low level signal, and controllable silicon T1 disconnects, and the motor two ends must not, motor shuts down, when X time second then, when control module is by the signal of IO2, knows zero passage, high level signal of control module output, drive controllable silicon T1 conducting, series excited machine and rectification module 11 electric after, this moment armature supply and Exciting Windings for Transverse Differential Protection current opposite in direction, motor begins counter-rotating, when N time second then, control module MCU exports a low level signal, controllable silicon T1 disconnects, the motor two ends must not be electric, and motor shuts down.When Y time second then, MCU can determine whether that Z circulation finish, and does not then change for the 1st step and continues beginning and just change if finish, if circulation is finished then low level signal of MCU output to MCU I/O shutoff T1, motor rotation end-of-job.
Fig. 6 is power supply wave shape figure of the present invention, and the along slope coordinate among the figure is a voltage, and lateral coordinates is the time, because be the alternating current of 50HZ, so one-period is 20MS (millisecond).Suppose that control module MCU detects zero passage at IO1 mains waveform A1, A2, A3, A4, MCUI/O will import a high level, make the T1 conducting, motor just changes, at M after second, control module MCU detects zero passage at IO2 mains waveform B1, B2, B3, AB, a period of time when MCUI/O will import a high level, motor counter-rotating.
More than be specifying of pulper embodiment of the present invention, but this embodiment is not in order to restriction protection scope of the present invention, all equivalences that does not break away from technical solution of the present invention are implemented or change, all should be included in protection scope of the present invention.
