Abstract
The utility model discloses an intelligent control device of a belt conveyer, which is characterized in that the intelligent control device comprises a PLC and a frequency converter, wherein the input end of the PLC is connected with an aggregate bin opening signal; the output end of the PLC is connected with the control signal input end of the frequency converter; and the output end of the frequency converter is connected with a belt conveying motor. A Schneider frequency converter is adopted. The intelligent control device of the belt conveyer can run at power frequency when the conveyer belt is in a feeding state, and run at lower speed when not in feeding, also can realize soft starting, and can remarkably save energy and reduce consumption.
Description
Technical field
The utility model belongs to the electrical control field of construction machinery and equipment, relates to a kind of band conveyor intelligence controlling device.
Background technology
The oblique belt transporter of domestic existing mixing plant generally all is to drag contactless switch by button, directly starts.This traditional mode makes when the aggregate conveyer is not reinforced, motor idle running, and speed is non-adjustable, and it is serious to waste energy, and has strengthened the operating cost of mixing plant.Because the long-term power frequency operation of motor, it is very uneconomical to cause oblique belt transporter to move; Simultaneously because motor can't adopt soft start and soft stop, mechanically produce severe impact, the wearing and tearing of acceleration mechanical have a strong impact on service life of belt.
The utility model content
The utility model wants the technical solution problem to provide a kind of band conveyor intelligence controlling device, this band conveyor intelligence controlling device can be in reinforced state power frequency operation at conveyer belt, do not run slowly when reinforced, can also realize soft start, significantly energy efficient.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of band conveyor intelligence controlling device is characterized in that, comprises PLC and frequency converter; The input end synthetism feed bin start signal of described PLC; The signal input end of the output termination frequency converter of PLC; The mouth of frequency converter carries motor to be connected with belt.
Described frequency converter is the Schneider frequency converter.
The beneficial effects of the utility model:
1, frequency-changing control system substitutes former direct Starting mode, and motor employing soft start and soft stop make speed governing smoothly electrodeless, and dependable performance reduces mechanically producing severe impact, reduces the wearing and tearing of machinery, saves and reduction maintenance cost about 30%;
2, adopt each section of PLC control operation acceleration, deceleration process, but saves energy 25%.
Calculate to produce one jar of concrete material, every jar of automatic production time is approximately 70S, and tiltedly the belt actual loading time is about 20S.As adopt variable frequency control, then can save electric energy about 30%.
Through actual measurement, be example with the oblique band conveyor of 37KW, current of electric is not about 26A when having material, and current of electric was about 86A when material was arranged.After adopting frequency converter, current of electric only is not (during zero load is that frequency is made as 20HZ) 11A when having material, and current of electric was 72A when material was arranged, and energy-saving effect is fairly obvious.
Description of drawings
Fig. 1 is a functional block diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, a kind of band conveyor intelligence controlling device is characterized in that, comprises PLC and frequency converter; The input end synthetism feed bin start signal of described PLC; The signal input end of the output termination frequency converter of PLC; The mouth of frequency converter carries motor to be connected with belt.Described frequency converter is the Schneider frequency converter.
The scheme that the utility model proposes has realized the intellectuality of oblique belt transporter control, adopt the V/F mode, regulate rotating speed of motor by the running frequency that changes motor, have mode flexibly, stable performance, reliable operation, energy-saving potential be big, prolong advantage such as electrical motor self service life.
The band conveyor intelligence controlling device comprises frequency converter and PLC; Getting electromagnetic valve (or PLC) signal of system's control aggregate bin receives on the L1 and L3 terminal of frequency converter (Schneider) as Acceleration Signal, frequency converter is with two sections speed control system operational modes, first section speed is made as 20HZ, second section speed is made as 50HZ: when aggregate bin is reinforced, electromagnetic valve is opened, the L3 closure makes the power-frequency voltage driving belt of frequency converter output 50HZ carry the motor high-speed cruising.When not reinforced, closed electromagnetic valve, L3 disconnects, and frequency converter output 20HZ voltage driving belt carries motor with low cruise, energy conservation.
Claims (1)
1. a band conveyor intelligence controlling device is characterized in that, comprises PLC and frequency converter; The input end synthetism feed bin start signal of described PLC; The signal input end of the output termination frequency converter of PLC; The mouth of frequency converter carries motor to be connected with belt.
