Abstract
The invention relates to a de-dusting device and in particular relates to a special de-dusting device for a vibrating screen, and belongs to the technical field of environmentally-friendly dry de-dusting. The screen surface of the vibrating screen of the de-dusting device is arranged in a sealing cavity, wherein a primary dust filter is connected to the upper part of the sealing cavity; the whole vibrating screen, the discharging port of the vibrating screen and a dust hopper under the vibrating screen are sealed in a secondary de-dusting sealing box; the upper part of the secondary de-dusting sealing box is connected to a secondary dust filter through a pipeline; and bag-type dust collectors are arranged in both of the primary dust filter and the secondary dust filter. The de-dusting device can be used for solving the problem of collecting and conveying the dust of the vibrating screen. The de-dusting device has the advantages that the collecting efficiency is high (above 95%), the processing cost is low, the investment is less, the occupied area is small, the service lives of the dust collectors are long, the construction period is short, and discharged gas from the dust collectors is inferior to the national effluent standard.
Description
Technical field
The present invention relates to the special-purpose dust arrester of a kind of dust arrester, particularly vibratory sieve, belong to environmental protection dry dedusting technology field.
Background technology
Vibratory sieve mainly is divided into linear vibrating screen, circular shale shaker, revolves the sieve that shakes, excitation type vibratory sieve, generally partly is made up of vibrator, screen box, supporting or suspension arrangement, transmission device etc.
Vibratory sieve is to utilize type vibration and the work of revolving of answering that the oscillator exciting produces, two motor synchronous reverse rotations make vibrator produce reverse exciting force during work, force sieve nest to drive screen cloth and do lengthwise movement, make the material on it be subjected to exciting force and the range of periodically dishing out forward, thereby finish the material screening operation.
The vibratory sieve working portion maintains static, and slides and makes material obtain screening along working face by material.The difficulty of vibratory sieve dedusting maximum just is the capture and the conveying of dust.Traditional bag-type dust trap is, the capture cover of a taper is set on the vibratory sieve compass screen surface, fuses with the dust conveyance conduit.Overflowing fume trap cover for fear of dust, must be negative pressure state in the fume trap cover; Deposit in pipeline for fear of dust, must adopt big air quantity to carry.Two factors all need powerful power, in case dust deposit in pipe interior, exhausting efficient will reduce greatly, the negative pressure state in the fume trap cover will be destroyed, dust will overflow fume trap cover, arresting efficiency can reduce significantly.In addition, adopt the vibratory sieve dust pelletizing system of cloth bag dedusting process, after having moved one or two years, cleaning shaft stops up, dust pelletizing system paralysis, vibratory sieve dust from flying.
Summary of the invention
For addressing the above problem, the invention provides a kind of improved dedusting vibratory sieve, can solve the capture and the transportation problem of vibratory sieve dust, capture rate height, processing cost are low, small investment, occupation of land is little, the deduster life-span long, the construction period is short, the deduster exit gas is lower than discharging standards.
Solving the scheme that technical problem of the present invention adopts is: the vibratory sieve compass screen surface is arranged in the annular seal space, annular seal space top connects a dust filter unit, ash bucket is encapsulated into the final dusting seal box under vibratory sieve integral body and discharging opening thereof and the sieve, final dusting seal box top connects the secondary dust filter unit with pipeline, all is provided with sack cleaner in dust filter unit and the secondary dust filter unit.
The top and the space, next door of described vibratory sieve compass screen surface annular seal space should be more than 2000mm, the interior space of final dusting seal box keeps the above space of 100mm, vibratory sieve compass screen surface annular seal space top captures mouth for the toroidal compass screen surface, and being flexible coupling by rubber is connected with a dust filter unit inlet.
The final dusting seal box is the integral body that screw connects into, to make things convenient for fast assembling-disassembling, the dust that cleaning is inner.Be provided with the pipeline that leads to the vibratory sieve compass screen surface in dust filter unit dust position that is captured, the useful dust under the filter can be returned vibratory sieve.The bottom of secondary dust filter unit is connecting the dust flue that the dust discharge valve is housed, when dust accumulation when a certain amount of, open valve and gather dust.
Sack cleaner in dust filter unit and the secondary dust filter unit to dust-filtering after, clean gas is discharged through small-sized fan (3.0kW).
The invention has the beneficial effects as follows: 1. do not have pipeline etc. to draw factory building, also do not have equipment such as deduster, blower fan, chimney, do not take up an area of no view visual pollution; 2. need not to be equipped with the operator, easy to maintenance, expense is low; 3. power consumption is approximately 20% of dust settling pocket technique; 4. compare with dust settling pocket technique and save investment about 20~30%; 5. guarantee that the dust catching rate reaches more than 95% for a long time, deduster outlet dustiness<50mg/Nm
3, the dust content<10mg/m of operating point

Description of drawings
Fig. 1 is an apparatus structure schematic diagram of the present invention.
Each label is represented successively among the figure: vibratory sieve 1, compass screen surface capture mouthfuls 2,3, the dust filter units 4 of being flexible coupling, material blanking tube 5, final dusting seal box 6, pipeline 7, secondary dust filter unit 8, dust flue 9, dust discharge valve 10, ash bucket 11, discharging opening 12.
The specific embodiment
Embodiment: referring to Fig. 1, the vibratory sieve 1 below material enters by material blanking tube 5, discharge from vibratory sieve bottom ash bucket 11 and end discharging opening 12 the screening back.The compass screen surface of vibratory sieve 1 is sealed by seal closure, toroidal is set on seal closure captures mouth 2,3 be connected with being flexible coupling with plastic cement between the dust filter unit 4 of sieve top, in the dust filter unit 4 conventional sack cleaner is housed, the dust that dust filter unit 4 traps is by pipeline (hiding relation, do not draw) directly enter vibratory sieve 1, special deashing device need not be set, clean gas is then discharged by 3.0kW small-sized fan (not drawing).The integral body of vibratory sieve 1 adopts final dusting seal box 6 to seal, and at final dusting seal box 6 upper end afterbodys final dusting pipeline 7 is set, and is connected with secondary dust filter unit 8 bottoms, and the dust under capturing is discharged by dust discharge pipeline 9 and dust discharge valve 10.
Present embodiment is applied to Yongchang, Yunnan silicon industry Co., Ltd (supporting) vibratory sieve in powder process workshop, and gross investment is 250,000 yuan, and the duration is 30 days, be constructed and put into operation in January, 2010, dust removing effects is remarkable, dust catching rate>95%, deduster outlet dustiness<50mg/Nm
3, be lower than discharging standards; Dust content<the 10mg/m of operating point
3, meet national occupational health standard.Compare with dust settling pocket technique, gross investment is saved 200,000 yuan, and the duration shortens 30 days, and annual the saving moved 100,000 yuan of the electricity charge.
