Abstract
The utility model relates to electric control equipment, in particular to a control system of a woodworking environmentally-friendly dust removing fan. The woodworking environmentally-friendly dust removing fan comprises an electric control cabinet 1 and a cabinet door 2 arranged on the electric control cabinet 1, wherein the electric control cabinet 1 comprises a frequency converter 3 and a wind-pressure transmitter 4; the cabinet door 2 is provided with an intelligent regulator 5 and a manual-automatic change-over switch 6; the wind-pressure transmitter 4 is connected onto a dust removing pipeline 7 by a wind-pressure transmission pipeline 8; the manual-automatic change-over switch 6 is connected with the frequency converter 3 by a guide line; the intelligent regulator 5 is respectively connected with the frequency converter 3 and the wind-pressure transmitter 4 by guide lines. The control system has the advantages that a user can change over the manual-automatic change-over switch 6 into a manual state during the maintenance when the intelligent regulator or the wind-pressure transmitter fails, and adjusts the output frequency of the frequency converter manually according to the current amount of the production tasks so as to save the power furthest.
Description
Technical field
The utility model relates to a kind of electric control system, is applied to carpenter's Environmental-protecting dust-removing frequency-changing control system of fan.
Background technique
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 utility model 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 utility model, 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 utility model:
As shown in Figure 1, carpenter's Environmental-protecting dust-removing blower fan control system of the present utility model, 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 the utility model electrical control cabinet front schematic view, 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.
