Abstract
The invention relates to electric control equipment, and particularly to a control system for a woodworking environment-friendly dust removing blower, which comprises an electrical control cabinet 1 and a cabinet door 2 arranged on the electrical control cabinet 1, wherein a frequency converter 3 and a wind pressure transducer 4 are arranged in the electrical control cabinet 1; an intelligent regulating instrument 5 and a manual-automatic transfer switch 6 are arranged on the cabinet door 2; the wind pressure transducer 4 is connected to a dust removing pipeline 7 through a wind pressure transmission pipeline 8; the manual-automatic transfer switch 6 is connected with the frequency converter 3 through a conducting wire; and the intelligent regulating instrument 5 is connected with the frequency converter 3 and the wind pressure transducer 4 respectively through conducting wires. According to the control system, when the intelligent regulating instrument or the wind pressure transducer breaks down, a user can switch the manual-automatic transfer switch to a manual gear during maintenance, and the output frequency of the frequency converter is adjusted manually according to the intensity of a current productive task, so as to save electric energy to the utmost extent.
Description
Technical field
The present invention relates to a kind of electric control system, be applied to carpenter's Environmental-protecting dust-removing frequency-changing control system of fan.
Technical background
In the driving control of carpenter's Environmental-protecting dust-removing blower fan, production task (opening the quantity of woodworking machinery) is different, and load is just different, so the power that needs is just different.In traditional air-blower control, fan motor is in case starting, just move with rated velocity, regardless of what (opening the quantity of woodworking machinery) of production task, fan motor all is that just formed: in production task many (quantity of driving woodworking machinery be'ss many) situation, air quantity is just not enough with the rated velocity operation, blast does not reach the requirement of environmental protection, and dust removing effects is bad; In production task few (quantity of driving woodworking machinery be'ss few) situation, air quantity is large again, and blast is superelevation again, although dust removing effects is good, has wasted a large amount of electric energy, and the blast of superelevation is to pipeline, and cloth bag all is a danger.So in the Environmental-protecting dust-removing blower fan, adopt frequency conversion automatic control system, at the blower fan main pipe wind pressure transmitter is installed, cooperate Computorized adjusting instrument, set the wind pressure value that can satisfy need of production in instrument, when production task is many, the dedusting dust-sucking hole of opening is many, cause just decline of blast in the pipeline, at this moment frequency conversion frequency just rises, when blast surpasses the wind pressure value of setting, the frequency conversion frequency just descends, and automation control apparatus is regulated the operation frequency of frequency variator automatically, thereby reaches the effect of energy-saving and frequency-variable.But do so a lot of drawbacks still arranged: after Computorized adjusting instrument fault or the wind pressure transmitter fault, maintenance during this period of time in, frequency converter frequency can't be regulated, acquiescence causes wasting electric energy with peak frequency operation.
Summary of the invention
When the present invention is intended to Computorized adjusting instrument or wind pressure transmitter fault, can get to manually by the hand automatic change-over, according to what of production task, manual tune frequency variator output frequency, saving power.
Carpenter's Environmental-protecting dust-removing blower fan control system of the present invention, comprise electrical control cabinet 1 and cabinet door 2 disposed thereon, comprise frequency variator 3 in the electrical control cabinet 1, wind pressure transmitter 4, automation control apparatus 5 is set on the cabinet door 2, hand automatic change-over 6, wind pressure transmitter 4 is connected on the cleaning shaft 7 by blast transmission pipeline 8, hand automatic change-over 6 is connected with frequency variator 3 by wire, and automation control apparatus 5 is connected with frequency variator 3, wind pressure transmitter 4 respectively by wire.
The user can arrange suitable blast at automation control apparatus 5, hand automatic change-over 6 is provided with manual control position and automatic control position, when switch is got to automatic control position, program default in the automation control apparatus 5 can according to how many automatic output frequencies of regulating frequency variator of production task, be stabilized in the setting value blast.When automation control apparatus or wind pressure transmitter fault, can be transformed into manual control position by handle automatic change-over 6, this moment can the manual tune frequency variator output frequency, maintenance automation control apparatus or wind pressure transmitter during this period of time in saving power, reduce unnecessary waste.

Embodiment
Below in conjunction with description of drawings the present invention:
As shown in Figure 1, carpenter's Environmental-protecting dust-removing blower fan control system of the present invention, comprise electrical control cabinet 1 and cabinet door 2 disposed thereon, comprise frequency variator 3 in the electrical control cabinet 1, wind pressure transmitter 4 arranges automation control apparatus 5 on the cabinet door 2, hand automatic change-over 6, wind pressure transmitter 4 is connected on the cleaning shaft 7 by blast transmission pipeline 8, and hand automatic change-over 6 is connected with frequency variator 3 by wire, and automation control apparatus 5 is connected with frequency variator 3, wind pressure transmitter 4 respectively by wire.
Fig. 2 is electrical control cabinet front schematic view of the present invention, automation control apparatus 5 is set on the cabinet door 2, automation control apparatus 5 passes through connection with frequency variator 3, when moving throw over switch 6 is got to automatic control position in the hand, program default in the automation control apparatus 5 can according to how many automatic output frequencies of regulating frequency variator of production task, automatically regulate the output frequency of frequency variator, when automation control apparatus or wind pressure transmitter fault, can be transformed into manual control position by handle automatic change-over 6, needs according to production task, the output frequency of manual tune frequency variator, the maintenance during this period of time in saving power.Behind Failure elimination, only need handle automatic change-over 6 to get to automatically, recover normally to use.
