Description
Technical field
The invention belongs to carpenter field, more particularly to a kind of carpenter's pulse filter bag central dust remover, for woodworking plus
The gas of dust caused by work carries out purifying and dedusting.
Background technology
Timber work is typically the basic production process of Furniture Factory, can produce many powder not of uniform size in process of production
Dirt, its dust are mainly derived from the processing operation such as saw, milling, plane and sanding, and such dirt dust concentration is larger, and health is caused to endanger
Evil.
The current dust pelletizing system overwhelming majority is using by the air with dust, by filter bag, little particle adsorbing powder dust is in filter bag
On, through clearing up filter bag after a period of time, or under using pulser, the dust adsorbed on filter bag is trembled, then carry out clear
Reason；Filter bag is directly cleared up, it is necessary to repeatedly dismantle, implement highly difficult, be adapted to small dust arrester；Dust is trembled down
Cleared up again afterwards, the dust cleaner used at present effectively can not all clean out dirt in time, easily cause blocking, reduce
The dust removal performance of dust pelletizing system.
Dust is more caused by timber work, and range of scatter is big, it is necessary to carry out dust removal operation using large-scale dust pelletizing system, by
Big in dust concentration, in dedusting, dust can be deposited on deduster bottom, be negative pressure state inside deduster, if clearing up not in time
The laying dust of bottom, in the process of circulation of deduster inner air, laying dust can be kicked up, laying dust can return to the air of non-dedusting once again
In, further increase dust concentration, make to be deposited on the dust on filter bag and accelerate to reach saturation state；Clear dirt in deduster at present
Device is difficult to meet large-scale dust pelletizing system, causes dust removing effects poor.
The control system of current deduster is the operation of simple control device, it is difficult to make the air quantity of air-introduced machine and remove
Air volumematching needed for dirt device, makes the energy consumption of whole deduster increase.
The content of the invention
It is an object of the invention to：A kind of carpenter's pulse filter bag central dust remover is provided, solves deduster due to air inducing
Air quantity and deduster the institute required airflow of the offer of machine mismatch, so as to cause the increased technical problem of the energy consumption of deduster.
The technical solution adopted by the present invention is as follows：
A kind of carpenter's pulse filter bag central dust remover, including dirt pocket, the upper box of the dirt pocket are provided with cloth bag and removed
Dirt device, air inlet and air outlet are provided with the upper box, and the air inlet connects dust collection pipe, the dust collection
Pressure sensor is provided with pipe, suction port is provided with the dust collection pipe, pneumatic operated valve, institute are provided with the suction port
State air outlet and be connected with air-introduced machine, motor, pressure sensor and the pneumatic operated valve of the air-introduced machine are electrically connected with PLC
Connect.
Further, the bag-type dust collector includes filter bag and pulse ash remover, and the pulse ash remover is set
Above the filter bag, the pulse ash remover electrically connects with the PLC.
Further, it is provided with flow-stopping plate between the air inlet and the bag-type dust collector.
Further, dust exhaust is provided with the lower box of dirt pocket, the dust exhaust includes dust scraping plate conveyer
Structure, the dust scraping plate for blowing lower box laying dust off is provided with the dust scraping plate conveying mechanism, and the dust scraping plate conveying mechanism connects
Connect drive mechanism.
Further, the dust scraping plate conveying mechanism is transmitted using conveying chain mechanism, and the dust scraping plate is arranged on described defeated
Send on the carrier chain of chain mechanism, the conveying chain mechanism drives the dust scraping plate to do the circulating in perpendicular in lower box
Dynamic, for the carrier chain by the sprocket transmission of the conveying chain mechanism, the sprocket is connected with decelerator, the decelerator with it is described
PLC electrically connects.
Further, belt scraping blade is provided with the dust scraping plate.
Further, it is additionally provided with the lower box and collects the feed opening that dust scraping plate scrapes dust, under the feed opening
Side is provided with lock gas ash-discharging device, and the lock gas ash-discharging device is using star-like closed lock gas ash-discharging device.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1. the dust exhaust makes dust scraping plate do shuttling movement by the way of chain drive, laying dust can effectively be scraped into
Feed opening, greatly reduce dust concentration caused by airborne dust in lower box, slow down dust on filter bag reach saturation state when
Between, that is, reduce the deashing frequency of bag-type dust collector.
2. being driven using chain to the dust scraping plate, deposition of the dust on transmission mechanism can be reduced, due to
There are gap, and real time kinematics on chain, can further reduce deposition, so as to reduce dust concentration；The dust exhaust volume
Small, technology arrangement is flexible, convenient to install and maintain.
3. belt scraping blade can increase the contact area between dust scraping plate and casing, so that dust is preferably scraped to blanking
Mouthful, effectively avoid dust from putting up a bridge and result in blockage.
4. due to being negative pressure state in casing, the dust after dust scraping plate is scraped is difficult to discharge through feed opening, using star-like envelope
Close latch gas ash-discharging device can be such that dust quickly discharges, and improve efficiency of dust collection.
5. being provided with flow-stopping plate between air inlet and filter bag, dust can be made to enter after casing, change wind direction, bulky grain
The impurity such as wood chip are slowly deposited on lower box bottom, have reached the pre- purpose gathered dust；Prevent dust from directly washing away filter bag simultaneously,
Filter bag is set to produce abrasion, so as to improve the life-span of filter bag.
6. when woodworking machine is started working, the pneumatic operated valve is opened, and pressure sensor passes the air pressure experienced
Enter in PLC, PLC frequency is adjusted according to working condition, so as to the working frequency of adjust automatically motor, made
Air quantity, blast needed for the air quantity of air-introduced machine, blast and dust pelletizing system remain best match, the power consumption of dust pelletizing system is begun
Minimum state is maintained at eventually, reaches the purpose of energy-conservation.When woodworking machine does not work, pneumatic operated valve is closed, the dust collection pipe
With the negative pressure increase in bag-type dust collector, after pressure sensor experiences the change of pressure, produce voltage signal and be sent to PLC
Controller, the PLC reduce air-introduced machine rotating speed, save electric energy.
7. a structure can handle the dusty gas of industrial high concentration, effectively improve production environment, and efficiency of dust collection
Height, dust removal efficiency reach 99.5%.
