Abstract
The utility model relates to a dust water separating device having a centrifugal rotary drum, which is mainly used for separating liquid mixture with solid particles, and comprises a machine body, a motor, and a centrifugal device which is driven by the motor. The utility model is characterized in that a water splash plate which rotates at a same axial line with the centrifugal rotary drum is arranged in the centrifugal rotary drum; a material outlet which is connected with the centrifugal device is provided with a filtering conveying belt which does intermittent linear motion; a vacuum dewatering chamber is positioned at the back of the filtering conveying belt and is communicated with a negative-pressure source. The water content of the treated liquid mixture is not more than or equal to 30%.
Description
The utility model relates to a kind of seperator of ash and water with centrifugal reel, is mainly used to separate the liquid mixture that has solia particle.
In order to prevent of the pollution of Industrial Boiler discharging flue dust to atmosphere, a kind of otherwise effective technique scheme is to adopt numb stone mist dust remover (seeing Chinese patent application No. 91222885.7), it with water curtain block flue dust the passage of process, make dust be unlikely to be discharged in the atmosphere.But another problem of thereupon bringing is to be acid dust-laden waste water and to have caused water pollution, i.e. secondary pollution again.For this reason, the multifeed clarifier of often having to be provided with is removed the dust that is blended in the water in the mode of natural sedimentation.Not only floor space is big for this, and work efficiency is low.A kind of possible technical scheme that addresses this problem is adopt the centrifuge with rotation rotary drum to dewater, but because the dust concentration of mixed liquor is lower, existing centrifuge all to be difficult to satisfy its dehydration requirement.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of seperator of ash and water is provided, and not only floor space is little for it, the work efficiency height, and can carry out Ash Water Separator effectively.
The technical scheme that realizes the utility model purpose is: a kind of seperator of ash and water, comprise body, motor and by motor-driven centrifugal device, its difference is: in centrifugal reel, water dumping plate with its coaxial line rotation is housed, the discharging opening that connects centrifugal device is provided with makes intermittently straight-line filtration conveyer belt, and the vacuum dehydration chamber is positioned at the back of conveyer belt and is connected with negative pressure source.
And rotary drum can be tapered, 55 °～60 ° at oblique angle, and the large awl end of rotary drum is towards discharging opening, and water fender is connected in the lower edge of rotary drum.
And, can be provided with the scraper plate that impels the dehydration dust to leave conveyer belt at the delivery end of conveyer belt.
And the filtration conveyer belt has inside and outside two-layer, and internal layer is a nylon leaching net, and skin is a stainless steel filtering net.
During the work of this seperator of ash and water, grey water mixed liquid enters the rotary drum of centrifugal device through charging aperture.Under action of centrifugal force, mixed liquor is thrown to the inwall of rotary drum by the water dumping plate, water is then through the filter screen at rotatory drum wall place and the dust separation that intercepts in filter screen, meanwhile, along with the forfeiture of moisture and the decline of viscosity, gravity will make grey aqueous mixtures overcome that centrifugal force and cohesive force are left inwall and drop on through discharging opening and filter on the conveyer belt, because the swabbing action of negative pressure further makes the most of residual moisture in the grey aqueous mixtures discharge through the vacuum dehydration chamber.Dust behind above-mentioned second dehydration is filter cake shape, its moisture content≤30%.Obviously, compared to existing technology, it is little that the utility model also has floor space, the work efficiency advantages of higher.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the cutaway view of signal the utility model structure.
Fig. 2 is the partial views in cross section of conveyer belt.
With reference to Fig. 1, Fig. 2, this seperator of ash and water comprises body 1, motor 2 and the centrifugal device 6 that is driven by motor 2, in centrifugal reel 8, the water dumping plate 7 that rotates with its coaxial line is housed, and the upper surface of this water dumping plate 7 is towards charging aperture 4.Concrete scheme can be: motor 2 drives rotating shaft 5 through belt gear 3, and rotary drum 8, water dumping plate 7 are connected mutually with rotating shaft 5 simultaneously, as: key connects.Rotary drum 8 is tapered, and oblique angle 12 is 55 °～60 °, and its conical surface is with stainless steel filtering net 10.
Described water dumping plate 7 preferably is positioned at the first half of rotary drum 8, if the lower or centrifugal effect of rotary drum 8 rotating speeds is not good enough, then can consider to be provided with one for 7 times again than its bigger water dumping plate 9 at aforementioned water dumping plate.
In the lower edge of rotary drum 8, preferably prolong the outer circumference water fender 11 that is connected, this can be avoided conical surface, the discharging opening 13 of the clockwise drum 8 of water (on a small quantity) that throws away to flow on the conveyer belt 14 that is positioned under it.
The discharging opening 13 that connects centrifugal device 6 is provided with makes intermittently straight-line filtration conveyer belt 14, and vacuum dehydration chamber 15 is positioned at the back of conveyer belt 14 and is connected with negative pressure source 16.Filter cake moisture content behind second dehydration is with≤30% like this.If will strengthen dehydrating effect, can also establish 2 or 3 vacuum dehydration chambers 15 along conveyer belt 14, distance is about 0.5 meter between per two Room.
In order to impel filter cake and conveyer belt 14 after the dehydration to be separated, 1 or 2 scraper plate 18 can be set at the delivery end 17 of conveyer belt 14.Like this, along with the motion of conveyer belt 14, static relatively scraper plate 18 just will be attached on the conveyer belt 14 filter cake shovel from.
The rectilinear motion at intermittence of conveyer belt 14 is that the intermittent movement by motor 9 realizes.Suggestion is adopted the time relay to control motor 19 and is done intermittently to rotate, and conveyer belt 14 every motions distance once is the spacing of every adjacent two vacuum dehydration chambers 15, and the time of staying after the motion once is 15～25 seconds.
When rotary drum 8 or filter the filter screen 10,20,21 of conveyer belt 14 when blocked, can under open state, introduce clear water continuously from charging aperture 4 and just can be removed.
