Description

A kind of dedusting Sanding Room and its control device

Technical field

The utility model belongs to carpenter field more particularly to a kind of dedusting Sanding Room and its control device, for carpenter The band dusty gas that industry generates carries out purifying and dedusting.

Background technology

Timber work is typically the basic production process of Furniture Factory, will produce many powder not of uniform size in process of production Dirt, dust are mainly derived from the processing operation such as saw, milling, plane and sanding, and such dust concentration is larger, causes to endanger to health Evil.Sanding Room is commonly used in timber work, and the dedusting Sanding Room being commonly used has：Positive pressure Sanding Room, negative pressure Sanding Room and Polishing table.

Positive pressure Sanding Room uses closed room body structure, is forcibly fed into fresh wind into room, indoor digging melt pit, and pond is built-in Water, air carries dust to be passed through from the melt pit water surface, into air duct.Cascade and fountain head are installed in air duct, again depositing dust, air discharge Workshop.The Sanding Room needs laydown area being located in room body, therefore area is larger, and cost is higher.Room body gate must be closed, opens the door When dust can be caused to leak, workshop condition pollutes again, and pass in and out it is inconvenient.The feeling that works long hours in room body is constrained, and makes an uproar Sound is higher.There is floss hole in outdoor, pollutes environment, and the recirculated water of melt pit can cause secondary pollution.

Negative pressure Sanding Room does not lean on the outside exhausting of exhaust fan using open room body structure into shipment door.Indoor digging Hole, the built-in water in pond, air carries dust to be passed through from the melt pit water surface, into air duct.Cascade and fountain head are installed in air duct, drop again Workshop is discharged in dirt, air.Compared to positive pressure Sanding Room, cost is relatively low, easy access.But still there is floss hole in outdoor, pollutes environment, And the recirculated water of melt pit can equally cause secondary pollution.

Polishing table uses mesa structure, polishing to be operated in table top progress, and the dust of generation is entered by the honeycomb hole of table top In polishing table, workshop is discharged by exhaust fan.The infrastructure cost is low.But polishing the dust generated may be elegant outward, causes Exhausting effect is not so good.And the dust generated is all discharged to outdoor, environmental pollution is larger.

There is a kind of Sanding Room of environmental protection at present, moist dedusting is substituted using dryness dedusting, the air of workplace is evacuated to After dirt pocket dedusting, clean air is discharged, in dedusting, dust can be deposited on dirt pocket bottom, be negative pressure shape inside dirt pocket State, if the dust accumulation of cleaning bottom can raise dust accumulation in the process of circulation of dirt pocket inner air not in time, dust accumulation can be once again It returns in the air of non-dedusting, further increases dust concentration, the dust being deposited on air filtration cartridge acceleration is made to reach saturation State.

Dust accumulation is carried out letting out ash using conveyer belt from dirt pocket at present in such a way that conveyer belt is transported, it can not only Consumption is big, and realization is complicated, lets out grey limited efficacy；Also by the way of fixed scraper plate 360 degree rotation, not using this mode Airborne dust can only be formed and be also difficult to adapt to large-scale deduster.

Utility model content

The purpose of this utility model is that：A kind of dedusting Sanding Room and its control device are provided, solved in dust removal process Dust concentration is big, dust accumulation is more, not in time and is not thorough due to cleaning dust accumulation and leads to the technical problem of dust removing effects difference.

The technical solution adopted in the utility model is as follows：

A kind of dedusting Sanding Room and its control device, including dirt pocket and the operating room that is arranged by the dirt pocket, institute It includes upper box and lower box to state dirt pocket, and ash exhauster is provided in the lower box, and the ash exhauster includes that scraper plate is defeated Mechanism is sent, the scraper plate for blowing lower box dust accumulation off, the scraping plate transmission mechanism connection are provided on the scraping plate transmission mechanism Driving mechanism.

Further, the drag conveyor uses conveying chain mechanism, the scraper plate to be arranged in the conveying chain mechanism On carrier chain, the conveying chain mechanism drives the scraper plate to do the shuttling movement in perpendicular, the conveying in lower box For chain by the sprocket transmission of the conveying chain mechanism, the sprocket is connected with retarder.

Further, it is provided with belt scraping blade on the scraper plate.

Further, deduster is provided in the upper box, the deduster includes air filtration cartridge and pulse dust cleaning Device is provided with air inlet on the dirt pocket, and the air inlet connects operating room by blast pipe, and the dirt pocket is also set up There are air outlet, the air outlet to be also associated with wind turbine, the discharge pipe of the wind turbine connects the operating room.

Further, a kind of dedusting Sanding Room control device, including logic control case are provided in the logic control case Logic controller is provided with the starting switch for starting Sanding Room, the logic controller and the wind on the logic control case The signal of the wind turbine is fed back to logic control case, the logic control case and the ash exhauster and pulse by mechatronics Deashing device is electrically connected.

In conclusion by adopting the above-described technical solution, the utility model has the beneficial effects that：

1. the ash exhauster makes scraper plate do shuttling movement by the way of chain drive, dust accumulation can effectively be scraped down Material mouth greatly reduces dust concentration caused by airborne dust in lower box, slows down dust on air filtration cartridge and reaches saturation state Time, reduce the deashing frequency of pulse ash remover.

2. being driven to the scraper plate using chain, deposition of the dust on transmission mechanism can be reduced, due to chain It is had the gap on item, and real time kinematics, deposition can be further decreased, to reduce dust concentration；The ash exhauster is small, Technology arrangement is flexible, convenient to install and maintain.

3. belt scraping blade can increase the contact area between scraper plate and babinet, to make dust preferably scrape to blanking Mouthful, effectively avoid dust bridging from resulting in blockage.

4. since Sanding Room is in carpenter's workshop, the air outside Sanding Room is with dust, if directly will polishing Air outside room is sent directly into operating room, and the staff of operating room can be made to be operated in the air with dust, this structure is by wind The discharge pipe of machine connects the operating room, and clean air after dedusting is sent into operating room, reduces operating room's dust concentration, simultaneously The discharge pipe nozzle of wind turbine is provided with cooling device, the cleaning wind that can be extracted out with cooling blower, suitable services person works.

5. using the operation conditions for the management Sanding Room equipment that control device can automate, the convenience used is improved.

6. structure can handle the dusty gas of industrial high concentration, workshop dust collection rate can be improved to 95% with On, effectively improve industrial environment.
