Fig. 2 is a kind of structural schematic diagram of filtering net cleaning condition checkout gear of the present invention.
Specific embodiment
The following description and drawings fully show specific embodiments of the present invention, to enable those skilled in the art to
Practice them.Other embodiments may include structure, logic, it is electrical, process and other change.Embodiment
Only represent possible variation.Unless explicitly requested, otherwise individual components and functionality is optional, and the sequence operated can be with
Variation.The part of some embodiments and feature can be included in or replace part and the feature of other embodiments.This hair
The range of bright embodiment includes equivalent obtained by the entire scope of claims and all of claims
Object.
As shown in Figure 1, in some illustrative embodiments, providing a kind of filtering net cleaning condition detection method, comprising:
101: filter screen being placed in the air inlet of detection cylinder, while blower being placed in detection cylinder, blower operates constantly, makes
It obtains outside air and is entered in detection cylinder by filter screen from air inlet.
102: starting blower, and blower uses speed regulation by constant torque.
Since power is equal to the product of revolving speed and torque, there are two freedom degrees for the control of blower.Motor invariable power and perseverance turn
Square is used in the performance indicator in electric machine speed regulation；Output torque is big when constant-power speed regulation refers to motor low speed, and output turns when high speed
Square is small, i.e., output power is constant；Speed regulation by constant torque refer to motor high speed, low speed when output torque it is equally big, i.e., high speed when
Output power, output power is small when low speed.
It can guarantee that equipment sets air quantity in such a way that permanent torque controls, there is stable application to need production application
It asks, while can judge to mention with the timely maintenance equipment of equipment user in time again by detecting rotary speed data, reaches more preferable
Equipment usage economy.
103: the revolving speed of speed probe real-time detection blower, and the rotary speed data that will test is uploaded to data processing mould
Block.The calculating and analysis that controller completes data can be used in data processing module.
104: data processing module analyzes filtering net cleaning degree according to rotary speed data.It is provided for filtering net cleaning state
One measurement standard.
Blower is to ensure that flow through the total blast volume of filter screen unit time constant using speed regulation by constant torque, passes through filter screen
Tuyere air volume L and the relationship of wind speed V are as follows:
L=3600 × F × V；
In above formula, F is air port draught area, unit m2；V is the air port mean wind speed measured, unit m/s.
For example setting tuyere air volume is 50M3/ H such as wants homeostasis tuyere air volume, then the filter screen the dirty, it is required that blower turns
Speed is higher, i.e. raising wind speed.
105: blower rotates so that the interior generation negative pressure of the detection cylinder, detects air duct described in pressure difference switch real-time detection in cylinder
Interior pressure difference.It is whether excessively dirty that filter screen is characterized by the on-off of pressure difference switch, the pressure difference that can preset filter screen both sides is small
Can be characterized when 200Pa filter screen be it is clean, as filter screen is more and more dirtier, the negative pressure generated in detection cylinder is bigger, when reaching
When to preset value, pressure difference switch conducting, pressure difference switch transmits signal to data processing module, data processing module, that is, exportable control
Signal processed, control alert device are prompted, and alert device section is chosen as LED light or buzzer.
As shown in Fig. 2, in some illustrative embodiments, providing a kind of filtering net cleaning condition checkout gear, comprising:
Cylinder 1, blower 2, speed probe 3, data processing module and pressure difference switch 5 are detected, filter screen 4 is arranged in the air inlet of detection cylinder 1,
For the setting of blower 2 in detection cylinder 1, blower 2 uses speed regulation by constant torque.
Wherein, speed probe 3, for acquiring the revolving speed of blower 2 and rotary speed data being uploaded to data processing module.Number
According to processing module, for analyzing filtering net cleaning degree according to rotary speed data.
It should also be appreciated by one skilled in the art that various illustrative logical boxs, mould in conjunction with the embodiments herein description
Electronic hardware, computer software or combinations thereof may be implemented into block, circuit and algorithm steps.In order to clearly demonstrate hardware and
Interchangeability between software surrounds its function to various illustrative components, frame, module, circuit and step above and carries out
