Detailed description of the invention
Fig. 1 is a kind of negative-pressure type dust arrester including full-closed material guide slot.The specifically horizontal dust remover 1 installed above at full-closed material guide slot 2 forms.Horizontal dust remover 1 is contained in the top of full-closed material guide slot, and mother tube 3 accesses from the front upper of deflector chute, and blanking point 5 is just in the lower section of mother tube and deflector chute junction.The front end of whole deflector chute is additionally provided with ash bucket 4, a set of spray equipment it is additionally provided with in full-closed material guide slot, wherein the shower nozzle 6 of spray equipment is located at the rear portion of full-closed material guide slot 2, and is provided with double-deck dust-break curtain 7 in the rear end of deflector chute, is used for preventing the dust in deflector chute from outwards releasing.Full-closed material guide slot is contained in above ribbon conveyer, and the material-conveying belt 8 of ribbon conveyer runs in full-closed material guide slot from front to back, is carried to the back-end by the material fallen at blanking point 4 from mother tube 3.
Horizontal dust remover 1 have employed negative-pressure type sack cleaner, this belongs to blowing-out electronic vibration type cleaner, by inlet scoop, and filter chamber, fan house, vibrated system, exhaust outlet, the capital equipment composition such as electric cabinet, subsidiary deafener, rosette, the adnexa such as firm banking.
Negative-pressure type sack cleaner can be installed on the spot in any airborne dust point position, directly gathers dust, and direct dust discharge is reclaimed, it is not necessary to lay longer dust suction and dust discharge pipeline.The deashing work of this machine is completed by electric motor of shaker timing two groups of flat cloth bags of mechanical beating odd even, produces asynchronous to clapping vibrations, make laying dust more thoroughly peel off cloth cover during beating.
Negative-pressure type sack cleaner can coordinate installation with double-seal material guide chute or full-closed material guide slot or head seal closure, controls overflowing of dust, and dust removing effects is more preferable.
During operation, negative-pressure type sack cleaner realizes linkage with ribbon conveyer by PLC is program control, it is not necessary to manual operation, the fully automated execution of all working program.
The present embodiment is except horizontal dust remover, it is also possible to use centrifugal vertical type dust-cleaning equipment.
Two, full-closed material guide slot
Fig. 2 illustrates the cross section of full-closed material guide slot 2, and full-closed material guide slot is to be made up of one piece of curved cover plate 12, two pieces of side plates 11, anti-overflow skirtboard 13, wear-resistant slide plate 14, fixed support 17, pedestal 19, ribbon conveyers.
Curved cover plate 12 raises up, and the both sides of curved cover plate are connected by bolt 18 with the upper end of two blocks of side plates 11 respectively.
Every piece of side plate 11 top is erection part and bottom is lateral bending portion, has been bolted anti-overflow skirtboard 13 inside erection part, the inside lateral bending in lateral bending portion of side plate 11 and be fixed with wear-resistant slide plate 14 above with bolt.
The dual-side of the material-conveying belt 8 of ribbon conveyer stretches between lower end and the wear-resistant slide plate 14 of the anti-overflow skirtboard 13 in both sides.
The both sides of the edge of material-conveying belt are clamped by the lower end of anti-overflow skirtboard 13 with wear-resistant slide plate 14, and the lower end of anti-overflow skirtboard is provided with wear rib 15, wear rib use high-abrasive material to make and with the upper surface of material-conveying belt side, the upper surface of wear-resistant slide plate contacts with the lower surface of material-conveying belt side, design such sealing structure, one is can effectively to prevent transported material to outward leakage, and two are to ensure that the operation of material-conveying belt is unobstructed.
Wear-resistant slide plate is that superhigh molecular weight polyethylene material is made, and utilizes wear-resistant slide plate to replace the side carrying roller of common deflector chute, makes material-conveying belt be supported continuously, will not produce side leakage because of phugoid oscillation in operation.
Flat idler 16 is arranged on the lower section of belt, the i.e. mid portion along material-conveying belt length and installs multiple flat idlers by the spacing set so that material-conveying belt 8 is held by flat idler from below.
The lateral bending portion of side plate 11 bottom is connected with pedestal 19 by fixed support 17；
At the interface being arranged above with for connecting negative-pressure type dust arrester of curved cover plate, negative-pressure type dust arrester is arranged on above curved cover plate, and the inlet scoop of negative-pressure type dust arrester is connected with interface reserved on curved cover plate.Negative-pressure type dust arrester can use Horizontal dedusting device, or vertical dust removing device.
Assume responsibility for most of weight of material owing to being located at the flat idler bottom material-conveying belt, make both to have decreased between material-conveying belt side and slide plate frictional force, and sealing effectiveness is more preferable.
The present embodiment is coordinated with anti-overflow skirtboard by wear-resistant slide plate, it is designed to the unique texture being clipped in the middle by material-conveying belt, by completely isolated for deflector chute interior or exterior space, forms good negative pressure space, in the middle of deflector chute, the most also it is additionally provided with double-deck dust-break curtain 7, thoroughly solves the problem that material is revealed, flown upward.
The reliability of the full-closed material guide slot of the present embodiment is high, and good airproof performance, and service life was long, up to 20 years.In addition to negative-pressure type cleaner unit composition dust arrester, the full-closed material guide slot of the present embodiment can also be individually used for those use occasions needing to carry material under the conditions of hermetically sealed, and leakage or the permeation effects by external environment condition occur when can effectively prevent from carrying material.
During installation, by the top of the curved cover plate 2 that above-mentioned negative-pressure type sack cleaner is arranged on full-closed material guide slot, wherein reserved above the inlet scoop of negative-pressure type sack cleaner and curved cover plate seam connects into an entirety, constitutes a complete cleaner.
The present embodiment by negative-pressure type sack cleaner and full-closed material guide slot with the use of, be the brand-new change of Comprehensive Dust Control equipment, be the optimal method of current dust removing effects, be also the best equipment fit system recommended of the present embodiment.
Good sealing effect due to full-closed material guide slot, it is possible to be isolated in deflector chute by dust completely, after negative-pressure type sack cleaner processes, on-the-spot dust in air content is less than 9 milligrams/cubic metre, and treating flour dust effect is ideal.
The present embodiment this novel dust removing equipment, solve the various tradition problems such as cleaner unit floor space is big, consumed energy is big, maintenance capacity is big, investment is big, operating cost is high, secondary pollution is the most up to standard, fully meet the requirement of GB16248-1996 " respirable dust sanitary standard in air of workplace ".
Above-described this utility model embodiment, is not intended that the restriction to this utility model protection domain.Any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in claims of the present utility model.
