The energy saving, consumption reduction, cost reduction and efficiency enhancement are basic targets of enterprise operation, the compact spinning frame is used as a working procedure with higher energy consumption in the spinning procedure, the number of the machines is large, the power of the motor is high, the energy consumption of the compact spinning frame determines the cost of energy consumption per ton yarn, and the energy consumption of the broken end cotton suction motor of the compact spinning frame is particularly outstanding.
After the broken ends of the spun yarn spindles are broken, the broken white flowers are sucked into a tail filter screen through a cotton suction flute pipe, and are manually picked up. 7.5kw cotton suction motor is started by PLC control AC contactor, using 380V, 50HZ fixed frequency control, no matter how many broken ends, the generated white flowers, cotton suction fan always keeps the highest full frequency 50HZ running, the motor power consumption is higher continuously.
Disclosure of Invention
Aiming at the technical defects, the utility model aims to provide a frequency conversion device of a broken end cotton suction fan of a JWF1566 spinning frame.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a frequency conversion device of a broken end cotton suction fan of a JWF1566 spinning frame, which comprises a motive power distribution box, and is characterized in that a 7.5KW frequency converter, a micro-differential pressure transmitter and an intelligent cotton suction fan control module are additionally arranged in the motive power distribution box; the micro-differential pressure transmitter is connected with a frequency converter, and the frequency converter is connected with an intelligent cotton suction fan control module.
The utility model has the beneficial effects that: according to the basic rule of broken ends of the spinning frame and the thickness degree of a cotton layer adsorption filter screen after broken ends, the device successfully changes the fixed power frequency of the original 7.5kw motor into variable frequency operation by using a variable frequency technology and a micro-pressure difference constant-voltage detection signal, effectively reduces the energy consumption of a cotton suction fan, and achieves the purposes of energy conservation and consumption reduction.
Drawings
In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, it being obvious that the drawings in the following description are only some embodiments of the utility model, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
Fig. 1 is a schematic diagram of a frequency conversion device of a broken end cotton suction fan of a JWF1566 spinning frame provided by the utility model;
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, a frequency conversion device of a broken end cotton suction fan of a JWF1566 spinning frame comprises a motive power distribution box, wherein a 7.5KW frequency converter, a micro-pressure difference transmitter and an intelligent cotton suction fan control module are additionally arranged in the motive power distribution box; the micro-differential pressure transmitter is connected with a frequency converter, and the frequency converter is connected with an intelligent cotton suction fan control module
Working principle:
firstly, a frequency converter is arranged in a power distribution box to control a cotton suction motor, and an original alternating current contactor is used as a starting signal control end of the frequency converter. When the cotton cleaner is started initially, the cotton suction fan can be started only by about 40HZ, the later stage is controlled by a micro-differential pressure constant-pressure detection signal, when the number of the broken cotton is more, the frequency conversion can be increased along with the reduction of the number of the pressure sensor, and when the number of the broken cotton is increased to a set value, the alarm lamp arranged on the roof of the vehicle blinks (the alarm lamp can give an alarm after reaching 45 HZ), a driver is prompted to pick the cotton, and the cotton suction motor returns to the 40HZ state again after the cotton is picked up.
The device is characterized in that a frequency converter of 7.5KW is additionally arranged in an existing power distribution box, a micro-pressure difference transmitter is arranged, an intelligent cotton suction fan control module is arranged, the original fixed frequency is 50HZ through a frequency conversion control technology, the frequency converter performs frequency control of 40 HZ-45 HZ through a micro-pressure difference constant pressure detection signal according to the thickness of a cotton layer of a cotton suction filter screen, and when the frequency reaches 45HZ, automatic alarm is performed to draw flowers, so that the energy-saving effect is achieved.
The device can save 25% -50% of electricity (according to different varieties) on the basis of original electricity consumption, 319.34-degree electricity can be saved every week by a 1080-spindle spinning frame, 15328.32-degree electricity can be saved by a year according to 48 weeks, and a 189-trolley of the company can save one year: 2897052.48 degrees of electricity, each degree is calculated according to 0.35 yuan, 101.39 ten thousand yuan can be saved each year, meanwhile, the running load of the motor is adjusted along with the variable frequency, the cotton suction motor can be better protected from being damaged, the working efficiency of a car blocking worker is improved, and the effects of energy conservation and consumption reduction are achieved.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
