Embodiment
the utility model is not subject to following embodiment's restriction, can determine concrete mode of execution according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is to be all described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in accompanying drawing 1,2, this frequency control of motor speed kiln tail high-temperature blower comprises frame 1, kiln tail blower fan 2, drive motor 3 and frequency changer controller, frame 1 left part is installed with kiln tail blower fan 2, frame 1 right part is installed with drive motor 3, the pto＝power take-off of drive motor 3 links together by the fan shaft of coupling and safety clutch and kiln tail blower fan 2, power input terminal and the power supply of frequency changer controller are electrically connected, and the tenminal block of the power output terminal of frequency changer controller and drive motor 3 is electrically connected.When lime rotary kiln 4 is produced, raw coal in former coal-hole 5 is sent into coal mill 7 by raw coal feedway 6, the discharge of coal mill 7 is connected with the material feeding mouth of the kiln tail firing chamber 9 of lime rotary kiln 4 by coal dust delivery pipe 8, former work stone 10 enters kiln tail firing chamber 9 by the material feeding mouth of lime rotary kiln 4, kiln tail blower fan 2 is sent into air in kiln tail firing chamber 9 simultaneously, kiln hood blower fan 11 is sent into air by the kiln hood of lime rotary kiln 4 in lime rotary kiln 4, in process of production due to the requirement of production technology, the air quantity that need to regulate kiln tail blower fan 2 to blow, the tail gas of kiln tail firing chamber 9 and lime rotary kiln 4 interior generations is discharged through kiln tail dust collector 13 and exhaust fan 14 by tail gas comb 12.The utility model can be controlled the startup of drive motor 3 by frequency changer controller, speed change, stop adjusting with standby the air quantity that regulates kiln tail blower fan 2 to blow, adjusting speed accuracy is higher, while normally operation due to equipment without fluid coupling and constituent, do not need to install additional cooling water and hydraulic pressure wet goods article of consumption, so maintenance cost is lower, calculate according to reality, after kiln tail blower fan 2 changes frequency changer controller control into by fluid coupling, energy-saving power has improved 1 18, save the several 800,000 degree left and right of electricity, by 0.48 yuan of calculating of every degree electricity, year energy-conservation take approximately more than 360,000 yuan, in addition owing to having avoided drive motor 3 because of frequent on-load start and stop, also reduce the impact to drive motor 3 and parts, extend the life-span of motor.
can according to actual needs, above-mentioned frequency control of motor speed kiln tail high-temperature blower be made further optimization and/or improvements:
as shown in Figure 1, frequency changer controller comprises frequency conversion case 15, VFC touch screen 16 and frequency variator; Frequency variator is fixedly mounted on frequency conversion case 15 inside, and VFC touch screen 16 is fixedly mounted on frequency conversion case 15 outsides; The power input terminal of frequency variator is electrically connected by switch and power supply, and the tenminal block of the power output terminal of frequency variator and drive motor 3 is electrically connected; The communication terminal of VFC touch screen 16 and the communication terminal of frequency variator are electrically connected.Can also directly set the relevant control parameter of frequency variator by VFC touch screen 16, for example, control time and the frequency etc. of clockwise and anticlockwise, acceleration and the deceleration of drive motor 3 and control parameter, thus controlling equipment more easily.In high low speed operation process, steadily, running precision is high in performance, realizes precision and regulates, and in the time that fluctuation appears in load, rotating speed is constant.After using frequency variator to regulate, due to the use of filter capacitor in frequency variator, the power factor making is close to 1, has increased the active power of electrical network, thereby has saved the energy of reactive power consumption.Wattless power increases the heating of line loss and equipment, causes the reduction of electric network active power because of the reduction of reactive factor simultaneously.
according to actual needs, frequency conversion case 15 is provided with short circuit temporarily and removes the diverter switch of frequency variator.In actual use, when frequency variator needs transient service or break down or when other problems, short circuit removes frequency variator, still can guarantee the normal production of lime rotary kiln 4, uses convenient temporarily.
above technical characteristics has formed most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs non-essential technical characteristics, meets the demand of different situations.
