Abstract
The utility model relates to a wind pressure analog control system in fan control. The wind pressure analog control system comprises an electric control cabinet 1 and a cabinet door 2, wherein the cabinet door 2 is arranged on the electric control cabinet 1. The wind pressure analog control system is characterized in that the interior of the electric control cabinet 1 comprises a frequency converter 9 and a wind pressure transmitter 5; the cabinet door 2 is provided with a wind pressure control regulator 3; the wind pressure control regulator 3 and the frequency converter 9 are communicated through a lead; the wind pressure control regulator 3 and the wind pressure transmitter 5 are communicated with a lead; and the wind pressure transmitter 5 is connected with a dust delivery pipeline 7 through a wind pressure conveying hose 6. According to the system improved by the utility model, not only can wind pressure be changed to meet the requirement of the production process but also when the production tasks are unsaturated and the wind pressure rises, the wind rate can be automatically regulated to achieve the goal of energy saving.
Description
Technical field
The utility model relates to a kind of electrical control equipment, especially the display control program of the blast in the blower fan control.
Background technique
Produce similar carpenter (timber etc.), in the process of manufacture of processing enterprise, can produce a large amount of wood chips, dust.These wood chips, dust is owing to have a very wide distribution, and area is big, and quantity is stablized for greatly the blast of collecting device in the centralized collection process and is caused very big difficulty.
General electric control system is to stable blast, and the control of relative fixed air quantity is no problem, and equipment manufacturers are can be through calculating the size of confirming needed motor, making full use of and practicing thrift with cheap electric energy.
Yet, because the pipeline of collecting device is at wood chip, the collection of dust; In the course of conveying, owing to will collect the wood chip of conveying in the pipeline; The difference of the quantity of dust and determined the instability of blast; The size that air door control in production scene is cut down, what of the platform of starting shooting because of production task, or the like all determined the instability of blast and air quantity.
In the face of the air quantity of unsettled blast and variation, general equipment manufacturers are to select motor according to the capacity that can satisfy maximum wind pressure and air quantity of maximum when selecting capacity motor.So, the motor electric energy under any circumstance exporting and consume all is much the same.Like this, under the undersaturated situation of production task, just caused a large amount of waste of electric energy.In the production process of reality, the monitoring of blast and adjusting just seem quite important, in order to satisfy the requirement of production technology; General factory all is through simulation repeatedly; Estimate by rule of thumb and estimate to regulate blast, the digital value that neither one clearly shows, like this; Blast just is not so good, and also quite waste energy to satisfying of production technology.
This electric control system is through the detection to blast, and the blast adjuster of intelligence is given in conversion; The blast adjuster of intelligence is through the PID computing; Give frequency variator or other signal and can change driving element and remove drive motor, with regard to the solution of success this problem, realized that the real-time digital of blast shows; And can set the blast numerical value in any scope according to the requirement of production technology.That is to say that any different blast requirement of production technology can be set through the quantification that numeral shows and realize.
Summary of the invention
The utility model aims to provide and a kind ofly can change output frequencies automatically according to blast is different, thereby realizes rotation speed of fan control, the control system of saving power.
The variable frequency adjustment control system of the dedusting fan of the utility model comprises electrical control cabinet 1 and cabinet door 2 above that is set, and it is characterized in that: comprise frequency variator 9, blast transmitter 5 in the electrical control cabinet 1, blast regulating and controlling appearance 3 is set on the cabinet door 2; Between blast regulating and controlling appearance 3 and the frequency variator 9, be communicated with through lead respectively between blast regulating and controlling appearance 3 and the blast transmitter 5; Blast transmitter 5 connects ash feeding pipe road 7 through blast transporting hose 6.
Frequency variator 9 is used for the control of dedusting fan; Blast transmitter 5 is measured the blast in the ash feeding pipe road 7 in real time through blast transporting hose 6; And according to current signal to the blast regulating and controlling appearance 3 of the difference of blast output 4 ~ 20mA, blast regulating and controlling appearance 3 carries out the PID computing according to current signal, and outputs signal to frequency variator 9; Frequency variator 9 is according to the signal change output frequency; Make motor speed change the purpose of regulating the pipeline blast to reach, simultaneously, the wind pressure value that blast regulating and controlling appearance 3 also can display setting.
Described blast regulating and controlling appearance 3 is a kind of automation control apparatus; Be used with various kinds of sensors, transmitter, realize measurement demonstration, the automation control apparatus of physical quantitys such as temperature, pressure, liquid level, capacity, power and cooperate various final controlling element that electric heating equipment and electromagnetism, electronic, pneumatic valve are carried out PID adjusting and control, controlling alarm, data capture, record.
System after the utility model improves not only can change the requirement that blast satisfies production technology, and unsaturated in production task, when blast rises, can regulate air quantity automatically, reaches purpose of energy saving.
