Abstract
The utility model discloses a constant pressure air suction and dust removal device which comprises an induced draft fan, a closed pipeline, a pressure sensor, a frequency converter and a dust collection device. A dust outlet of equipment required to be subjected to dust removal is connected and communicated with the closed pipeline through a connecting pipeline; a valve is arranged on each connecting pipeline; the pressure sensor is arranged in the closed pipeline; a signal output end of the pressure sensor is connected with a signal input end of the frequency converter; a signal output end of the frequency converter is connected with a motor of the induced draft fan; an air suction port of the dust collection device is arranged at the tail end of the closed pipeline; an air inlet of the induced draft fan is connected to an air outlet of the dust collection device. The fan output power can be changed according to the number of the driven equipment needed to be subjected to dust removal, so that constant air pressure of a dust collection pipeline can be kept regardless of working conditions of the pipeline, the energy is saved, and the equipment loss is reduced.
Description
Technical field
The utility model relates to leather base cloth production field, in particular to a kind of constant voltage air-drafting and dust-removing device.
Background technology
In leather base cloth is produced, fluff, widen, all can produce the dusts such as soft flocks in the production process such as cropping, shearing machine especially, the dusts such as these soft flocks must be siphoned away by dust arrester, are brought together and collect.Existing conventional dust pelletizing system comprises closing pipe line and dust blower etc.By needing each equipment of dedusting to be connected with dust blower by closing pipe line in workshop, by dust blower, the dusts such as soft flocks are siphoned away and collected.Dust blower generally turns round according to fixed rotating speed, the power of its output is certain, and it is different according to the number of the equipment that needs dedusting of opening in the different workshops of production task, while so just causing the number of the equipment that needs dedusting of its drive many, blast in control of dust pipeline is low, when the number of the equipment that needs dedusting of its drive is few, blast in control of dust pipeline is too high again, not only waste air quantity, more cause unnecessary energy loss, the running of the long-term high power of dust blower, again loss equipment.
Utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, a kind of constant voltage air-drafting and dust-removing device is provided, how many this dust arresters can change according to the driven number that needs cleaner the power of blower fan output, and then make control of dust pipeline no matter under that operating mode, can keep constant blast, save the energy, reduced the loss of equipment.
For achieving the above object, technical solution of the present utility model is: a kind of constant voltage air-drafting and dust-removing device, and it comprises pipeline, pressure sensor, frequency converter and the dust collecting installation of air-introduced machine, sealing; Respectively need the dust mouth of the equipment of dedusting by connecting pipe, to be connected and to be communicated with the pipeline of sealing respectively, in each connecting pipe, be separately installed with valve; In the pipeline of sealing, pressure sensor is installed, the signal output part of pressure sensor connects the signal input part of frequency converter, and the signal output part of frequency converter connects the motor of air-introduced machine; The inlet scoop of dust collecting installation is arranged on the end of the pipeline of sealing, and the air inlet of air-introduced machine is connected to the air outlet of dust collecting installation.
In dust collecting installation described above, have dual stage filter apparatus, from inlet scoop to air outlet, front end first order filter is disk dust filtration device, and second level filter is large carrying food-basket dust filtration device; The front end of disk dust filtration device and large carrying food-basket dust filtration device has respectively the first dust to collect mouth and the second dust is collected mouth.
The valve of installing in the connecting pipe that the dedusting mouth of the described above equipment that respectively needs dedusting is connected and is communicated with the pipeline of sealing is operated pneumatic valve, and the air inlet of the cylinder of each operated pneumatic valve connects source of the gas by steam line by magnetic valve respectively; The signal input part of each magnetic valve is connected to the power supply signal output to the equipment in requisition for dedusting.Like this, once which needs the equipment of dedusting to quit work, just lost power supply with the magnetic valve of this equipment connection, this closed electromagnetic valve, the cylinder return of its control, operated pneumatic valve is closed, and dust arrester no longer needs the equipment dedusting of dedusting to this.Operated pneumatic valve has been realized and has been made the out-of-work equipment automatic trip of dedusting that needs from dust arrester, avoided dust arrester to continue suction dedusting to the out-of-work equipment that needs dedusting and to needing the generation of the negative effect that the equipment of dedusting brings, and the power consumption of saving dust arrester.
The utility model has been installed pressure sensor in the pipeline of sealing, once due to the actual increase of the equipment that needs dedusting connecting and the variation of the blast in the pipeline of the sealing that minimizing brings on the pipeline of sealing, pressure sensor is induction in time, signal is transferred to frequency converter, frequency converter is adjusted the power output of id-motor in time, blast in pipeline is adjusted in time, recover to set blast, blast in the pipeline that makes to seal keeps constant, avoided infringement excessive due to the blast in the pipeline of sealing and to dust collecting installation, also avoided not reaching because blast is too small the effect of dedusting.And make the machine operation of air-introduced machine under optimal power output, saved the energy, avoided the generation due to the excessive infringement that each equipment is caused of blast.Operated pneumatic valve is particularly installed in connecting pipe, and it the out-of-work equipment of dedusting that needs is stopped to dedusting fast, has further saved the energy especially, avoids the generation to the infringement of equipment.But need equipment shearing machine, the raising machine of dedusting and widen machine etc.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the control structure schematic diagram of operated pneumatic valve in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Fig. 1 Fig. 2, the present embodiment comprises pipeline 1, pressure sensor 3, frequency converter 4 and the dust collecting installation of air-introduced machine 5, sealing.Respectively need the dedusting mouth of the equipment 2 of dedusting by connecting pipe 6, to be connected and to be communicated with the pipeline 1 of sealing respectively, in each connecting pipe 6, be separately installed with operated pneumatic valve 8.In the pipeline 1 of sealing, pressure sensor 3 is installed, the signal output part of pressure sensor 3 connects the signal input part of frequency converter 4, and the signal output part of frequency converter 4 connects the motor 11 of air-introduced machine 5.The inlet scoop of dust collecting installation 13 is arranged on the end of the pipeline 1 of sealing, and the air inlet of air-introduced machine 5 is connected to the air outlet of dust collecting installation 13.In dust collecting installation 13, have dual stage filter apparatus, from inlet scoop to air outlet, front end first order filter is disk dust filtration device, and second level filter is large carrying food-basket dust filtration device; The front end of disk dust filtration device and large carrying food-basket dust filtration device has respectively the first dust to collect mouth and the second dust is collected mouth.The air inlet of the cylinder 9 of each operated pneumatic valve 8 connects source of the gas 10 by magnetic valve 12 in turn by steam line respectively.The signal input part of each magnetic valve 12 is connected to the power supply signal output to the equipment 2 in requisition for dedusting.
