Description
Technical field
The present invention relates to cyclone and cyclone dust extractor technical field, more particularly, to one kind are used for strengthening cyclone
Or the circular crack lining of cyclone dust extractor wearability.
Background technology
Cyclone, also known as cyclone hydraulic separators, is a kind of classifying equipoment of the non-homogeneous phase mixture of separation.Can use
Come to complete liquid clarification, solid phase particles washing, liquid degassing and desanding, solid phase particles classification and classification and
The several work such as the separation of two kinds of non-mutually soluble liquidss.
Cyclone operation principle is fairly simple, mainly uses centrifugal principle.Ore pulp warp under pressure
Mineral-feeding pipe tangentially enters housing, does gyration in shell, and the coarse granule in ore pulp is subject to larger
Centrifugal force and near wall, and flow downward with ore pulp simultaneously, finally discharged by bottom sand settling mouth；And thin
Grain, due to less by centrifugal force, be in rotary current center and move upwards, finally by overflow pipe with ore pulp liquid
Become overflow.
Cyclone dust extractor is a kind of dry type gas-solid separating device, and operation principle is the dusty gas institute using rotation
The centrifugal force producing, dust is separated from air-flow.Cyclone dust extractor is as a kind of common gas-solid
Segregation apparatuss, have structure simply, easy to manufacture, and cost and running cost are relatively low, in actual application
Operation, easy to maintenance, stable performance, the change strong adaptability of the factor such as the concentration to dusty gas and temperature
The advantages of.Cyclone dust extractor is mainly used in industrial dedusting, air sampling, selects the aspects such as powder, heat exchange,
It is most widely used a kind of cleaner in industry.But because high speed dusty gas stream is to cyclone dust extractor device
Strongly the washing away, so the abrasion of wall is extremely serious of wall.In the extreme circumstances, the thick steel plate of several millimeters is used
Just worn out by local less than half a year or even some months, thus severely impacted whole dust pelletizing system normally running.
Additionally, the high-speed rotation air-flow at wall makes the part dust being deposited on wall produce secondary fly-up,
The actual efficiency of this exactly cyclone dust extractor is difficult to the main cause more than 90%.Therefore, improve whirlwind further
The efficiency of dust collection of cleaner unit and anti-wear performance are always two important subject in dedusting technology.
No matter operationally, solid-liquid suspension or gas-solid mixture act in pressure for cyclone or cyclone dust extractor
Lower make violent centrifugal rotation motion, suspension or gas-solid mixture violent wash away under abrasion, cyclone
Or cyclone dust extractor internal face easily weares and teares.This not only can shorten the service life of cyclone or cyclone dust extractor,
And its classification, separation efficiency can be reduced due to the change of key position size, change overflow and underflow amount,
Thus deteriorating operational effect.Therefore, cyclone or cyclone dust extractor need to be made using high-abrasive material, or with resistance to
Liner made by mill material.With cyclone mining industry, chemical industry, oil, coal, light industry, environmental protection, food,
Many industrial department wide popularization and application such as medicine, weaving and the extensive application of cyclone dust extractor, both at home and abroad
Research to cyclone and cyclone dust extractor wear problem is very paid attention to.
Wear problem is cyclone and the very scabrous problem of cyclone dust extractor, for alleviating wear problem, research
Persons propose: make cyclone or cyclone dust extractor using high-abrasive material, or make liner with high-abrasive material.?
Make and set up in cyclone or cyclone dust extractor the selection of wear-resistant liner two ways using high-abrasive material
On, from the point of view of Financial cost, mostly tend to the latter, that is, inside cyclone or cyclone dust extractor
Set up wear-resistant liner.At present, cyclone or cyclone dust extractor lining wear-resistant material species are a lot, and conventional is resistance to
Mill material has cast stone, carborundum, aluminium oxide ceramics, abrasive rubber and polyurethane etc..These materials have it excellent
Point, but there is weak point simultaneously and to some extent.Cast stone, carborundum and aluminium oxide ceramics etc. are inorganic
Nonmetallic wear-resistant liner is although material anti-wear performance itself is very good, but the wear-resistant liner so made is overall
Property poor, in use, by slurry stream or gas-solid mixture washed away after easily broken, come off.This
The not only fractionated effect of shadow cyclone or cyclone separator, and when serious, fragment also can block cyclone,
Thus causing to stop production.The wear-resistant liner that the organic materials such as abrasive rubber, polyurethane make, inner wall smooth, easily
Small-sized cyclone in manufactured size high precision.Temperature relatively low, handled raw meal particle size is less, hardness relatively
Under the more perfectly round operating mode of low, particle shape, its anti-wear performance is preferable；But, temperature is higher, handled material
Under the operating mode that granularity is relatively thick, hardness is bigger, particle shape are more sharp, its anti-wear performance is then poor.Using common
When carbon gusset makes cyclone housing, either use the inorganic non-gold such as cast stone, carborundum and aluminium oxide ceramics
Belong to material, or make wear-resistant liner with organic materials such as abrasive rubber, polyurethane, all there is housing and lining
Larger difference in terms of mechanical mechanics property and thermal stability for the material, this equally can cause liner to be easy to become
Shape comes off, thus having a strong impact on fractionated performance and the service life of cyclone or cyclone dust extractor.
By above-mentioned discussion it is recognized that while having carried out numerous studies in terms of high-abrasive material, but it turns out that, rotation
The wear problem of stream device or cyclone dust extractor yet suffers from.Manufacture and design wear-resistant liner, improve cyclone or rotation
The wearability of wind cleaner unit, extending their service life always cyclone and cyclone dust extractor field does not have
The technical barrier overcoming.
Content of the invention
It is contemplated that overcome prior art defect it is therefore intended that provide a kind of low cost, processing technology simple,
Wearability is strong and is applied to the circular crack lining strengthening cyclone or cyclone dust extractor wearability.
For achieving the above object, the technical solution used in the present invention is: in cyclone or cyclone dust extractor cylinder
Cylinder and cone inwall set up circular crack lining.This liner is successively decreased by some sections of cylindrical tubes, some sections of internal diameters
Cone, circumferential weld, gusset, oval import composition；Between cylindrical tube or adjacent two sections of cone
There is a certain distance, form circumferential weld, the vertical height of circumferential weld is 5-40mm, each section of cylindrical tube and cone
It is fixed into integral lining by some gusset vertical weldings of liner outer wall, gusset width is 5-30mm, thickness
For 3-8mm, quantity is 3-5 block, is uniformly distributed；From top to bottom first cylindrical tube is provided with ellipse
Shape import, the minor axis length of oval import is more bigger than cyclone or cyclone dust extractor import internal diameter, with eddy flow
Device or cyclone dust extractor import docking；Circular crack lining cylindrical tube and cone diameter, than cyclone or whirlwind
The cylinder of cleaner unit and the little 10-60mm of cone diameter, that is, outer wall weld gusset width twice, highly with
Cyclone or cyclone dust extractor internal height are consistent, and coning angle is consistent with cyclone or cyclone dust extractor.
Due to adopting technique scheme, one kind proposed by the present invention is used for strengthening cyclone or cyclone dust extractor
The circular crack lining of wearability.Circular crack lining and cyclone or cyclone dust extractor shell are not welding or stick in one
Rise, but circular crack lining is directly placed in cyclone or cyclone dust extractor wall, by circular crack lining outer wall
The gusset of welding is held against cyclone or cyclone dust extractor inwall, thus fixing circular crack lining and cyclone or
Cyclone dust extractor shell, so saves technique and makes, be conveniently replaceable liner again.
After setting up circular crack lining in cyclone or cyclone dust extractor, during its work, solid-liquid slurry or gas-solid mix
Compound under the influence of centrifugal force, weares and teares to circular crack lining first, thus reducing to cyclone or whirlwind
The abrasion of cleaner unit wall, improves its wearability.And the main feature of circular crack lining is circumferential weld and circular crack lining
The design of outer wall gusset, it is 5-30mm that the gusset of circular crack lining outer wall makes distance between circular crack lining and wall, shape
Become certain annular space, this annular space is separated into semiclosed annular space by vertically vertical gusset simultaneously.
Solid-liquid slurry or gas-solid mixture under the influence of centrifugal force, larger close to side wall, then downwards of granule
Eddy flow, yet with the presence of circumferential weld, thicker solid particle is passed through circumferential weld by the downstream near side wall,
Enter in the annular space that circular crack lining and wall are formed, but the gusset due to circular crack lining outer wall welding
Exist, blocked the eddy flow entering solid-liquid slurry or gas-solid mixture in this space, made under this space of entrance
Row flow velocity sharp-decay, thus form low speed slurry stream or low speed flow.Solid particle in slurry stream or air-flow exists
Slowly fall under this descending flow velocity and Gravitative Loads, thus not causing to cyclone or cyclone dust extractor wall
Abrasion.Certainly solid particulate matter is inevitably contacted with circular crack lining, circular crack lining is caused wear and tear,
But the presence of circumferential weld, makes to form rotation at a high speed all the time near the solid-liquid slurry stream of circular crack lining or gas-solid mixture
The liquor stream turning or air-flow, thus significantly reduce the abrasion to liner.
Further, since being additionally arranged circular crack lining in cyclone or cyclone dust extractor, in cyclone classification work
When, due to the presence of circumferential weld and liner outer wall gusset make to be formed between circular crack lining and cyclone wall certain
Annular space, under the influence of centrifugal force, thicker granule has entered in circumferential weld solid-liquid slurry through circumferential weld
It may be difficult to again in the slurry to inside circular crack lining for the back-mixing after in the semi-circular space that lining and wall are formed, no
Influence whether detached grain graininess in overflow pipe, thus improve the work efficiency of cyclone；In the same manner, exist
After setting up circular crack lining, during cyclone dust extractor work, circular crack lining will be close to wall and is unfavorable for dust collection
Part downstream is changed into contributing to the radial flow of dust collection, considerably reduces reentrainment of dust, improves dedusting
Efficiency.The presence of circumferential weld, by low speed air cushion between wall and circular crack lining for the dust " suction ", makes cleaner unit
Interior cannot be formed upper dust-ring and lower ash ring, thus alleviating the abrasion to circular crack lining.High speed dusty gas stream not with
Cleaner unit wall contacts, so enhancing anti-wear performance.Because the processing and fabricating of circular crack lining is simple, make eddy flow
The cost of device or cyclone dust extractor does not almost increase, but efficiency, drag losses, wearability indices all have
Improve, service life also greatly prolongs.
The present invention compared with prior art, has the advantage that
1. in order to improve cyclone or cyclone dust extractor wearability, existing inner lining material mostly adopt carborundum,
Aluminium oxide ceramics etc. manufacture although these material wear abilities are stronger, but its high cost, manufacture inner lining process
More complicated, therefore can not popularization and application on a large scale.And for the present invention, circular crack lining material directly adopts
Ordinary carbon steel manufactures, low cost of manufacture, and manufacturing process is simple.
2. existing cyclone or cyclone dust extractor, when making cyclone housing using ordinary carbon steel, either
With Inorganic Non-metallic Materials such as cast stone, carborundum and aluminium oxide ceramics, or with abrasive rubber, polyurethane etc.
Wear-resistant liner made by organic material, all there is housing with lining material in mechanical mechanics property and thermal stability side
The larger difference in face, makes liner and cyclone or the welding of cyclone dust extractor shell or bonding become larger problem,
And this equally can cause, and liner is easily deformable to come off；In addition, so by liner and cyclone or cyclone dust removal
Device shell welds or bonds together, when liner serious wear needs to change it is impossible to only more changeable liner and increasing
The difficulty changed and cost are added.And for the present invention, circular crack lining and cyclone or cyclone dust extractor housing
The entirety being separate from, circular crack lining is placed directly in cyclone or cyclone dust extractor, by circumferential weld
The gusset of lining outer wall welding is fixed, it is to avoid the weldering of liner and cyclone or cyclone dust extractor wall
Connect or bonding problem, simultaneously when liner serious wear needs to change, can only change circular crack lining, so
Not only cost-effective and replacing facilitates.
3. the design of existing liner is all a complete entirety, by solid-liquid slurry or gas-solid mixture to eddy flow
The abrasion of device or cyclone dust extractor shell is fully converted to the abrasion to liner.And for the present invention, and conventional
The structure of liner is different, and it is additionally arranged the design of circumferential weld within the liner, solid-liquid slurry or gas-solid mixture from
In the presence of mental and physical efforts, larger, the then downward eddy flow close to side wall of granule, yet with the presence of circumferential weld,
Thicker solid particle is passed through circumferential weld, entrance circular crack lining and wall to be formed by the downstream near side wall
In annular space, but simultaneously again due to the presence of the gusset of circular crack lining external welding, block this space of entrance
Interior solid-liquid slurry or the eddy flow of gas-solid mixture, make the descending flow velocity sharp-decay in this space of entrance, thus shape
Become low speed slurry stream or air-flow.Under the descending flow velocity of solid particle here in slurry stream or air-flow and Gravitative Loads slowly
Fall, thus not causing to cyclone or cyclone dust extractor wall to wear and tear.Certainly solid particulate matter can not be kept away
To contact with circular crack lining with exempting from, it be caused wear and tear, but the presence of circumferential weld, make consolidating near circular crack lining
Slurry stream or gas-solid mixture cannot form liquor stream or the air-flow of high-speed rotation all the time, thus significantly reduce right
The abrasion of circular crack lining.I.e. this invention greatly reduces solid particle to wall and circular crack lining from mechanism
Abrasion, the wearability of raising cyclone or cyclone dust extractor and service life.
4. existing cyclone or cyclone dust extractor, its liner and wall are bonded directly together, between be not free
Gap, cyclone or cyclone dust extractor work when although compared with coarse granule be subject to larger centrifugal force and to wall
Motion, but the rotational flow due to solid-liquid slurry or gas-solid mixture, have been arrived the relatively thick solid of wall unavoidably
Granule and back-mixing is in overflow slurry or air-flow, thus reducing classification efficiency or the cyclone dust extractor of cyclone
Efficiency of dust collection.And for the present invention, circular crack lining and wall between shape different from the structure of conventional liner
Become certain annular space, entered behind this space through circumferential weld under the action of the centrifugal force compared with coarse granule, can only
Slowly fall through underflow opening exclusion it may be difficult to back-mixing, in overflow slurry or air-flow, thus improves rotation again
The stream classification efficiency of device and the efficiency of dust collection of cyclone dust extractor.

Enclose and be not limited to described content.
Embodiment 1: this is used for strengthening cyclone or the circular crack lining of cyclone dust extractor wearability includes some sections of circles
Cone 2 that column casing body 1, some sections of internal diameters successively decrease, circumferential weld 3, gusset 4, oval import 5.As Fig. 4
Shown, in the present embodiment, circular crack lining is used in cyclone, if interior lining is provided with arterial highway circumferential weld, ring
The vertical height of seam is 5-40mm.Circular crack lining is generally 5-30mm, that is, in circumferential weld with the spacing distance of wall
The gusset width of lining outer wall welding is 5-30mm, and gusset is vertically welded in the outer of each section of cylindrical tube and cone
On wall, connect integral, gusset thickness is 3-8mm, quantity is 3-5 block, is uniformly distributed.Liner
Cylindrical tube and cone diameter are less than the cylinder of cyclone or cyclone dust extractor and cone diameter
10-60mm, i.e. the twice of outer wall welding gusset width, highly with cyclone or cyclone dust extractor internal height one
Cause, coning angle is consistent with cyclone or cyclone dust extractor.Oval import is arranged on first circle from top to bottom
On column casing body, the minor axis length of oval import is more bigger than cyclone or cyclone dust extractor import internal diameter, with rotation
Stream device or cyclone dust extractor import docking.
In the present embodiment, circular crack lining is used for cyclone, circumferential weld vertical height is 10mm, outside circular crack lining
The gusset thickness of wall welding is 3mm, and width is 15mm, and the quantity of gusset is 4 pieces, and gusset is vertically vertical
It is welded on the outer wall of circular crack lining, uniform welding is in circular crack lining four positions all around.The present embodiment
The a diameter of 280mm of middle cyclone cylindrical tube, cone angle is 20 °, therefore circular crack lining cylindrical tube internal diameter is
250mm, cone angle is 20 °.As shown in figure 4, for setting up the hydrocyclone structure figure after circular crack lining.
Its work process is as follows: solid-liquid slurry is entered in cyclone cylindrical tube by mineral-feeding pipe under feed force
Portion, but the presence of circular crack lining, it is to avoid the abrasion to cyclone wall for the solid particle.Solid-liquid slurry from
In the presence of mental and physical efforts, carry out eddy flow inside cyclone, larger close to side wall, then to backspin of granule
Stream, however on circular crack lining circumferential weld presence, near side wall downstream by thicker solid particle pass through ring
Seam, enters in the annular space that circular crack lining and cyclone wall are formed, but due to circular crack lining outer wall muscle
The presence of plate, has blocked the eddy flow of solid-liquid slurry, makes the descending flow rate attenuation of solid-liquid slurry, forms low speed slurry
Stream.Slowly fall under the descending flow velocity of solid particle here in slurry stream and Gravitative Loads, the thicker solid of granule
From underflow opening exclusion.The less solid particle of particle diameter is subject to centrifugal force little, is in rotary current center and with ore pulp
Liquid moves upwards, and finally being discharged by overflow pipe becomes overflow.In the process, solid-liquid slurry is directly and ring
Seam liner contact, abrasion, thus not cause to cyclone wall to wear and tear.Although in solid particle and circumferential weld
Lining contact, but the presence of circumferential weld, cannot form the slurry stream of high-speed rotation all the time near the solid-liquid slurry stream of liner,
Thus significantly reducing the abrasion to circular crack lining, that is, improve the wearability of cyclone, extend cyclone
Service life.
Embodiment 2: this be used for strengthening the circular crack lining of cyclone or cyclone dust extractor wearability as shown in Figure 1, Figure 2,
Shown in Fig. 3.Its structure simply relevant parameter same as Example 1 is different.Circular crack lining is used by the present embodiment
In cyclone dust extractor, as shown in figure 5, for setting up the cyclone duster structure figure after circular crack lining.In this reality
Apply in example, circumferential weld vertical height is 8mm, the gusset thickness of circular crack lining outer wall welding is 3mm, and width is
10mm, the quantity of gusset is 4 pieces, and gusset is vertically vertically welded on the outer wall of circular crack lining, uniform welding
In circular crack lining four positions all around.The a diameter of 380mm of cyclone dust extractor cylindrical tube in the present embodiment,
Cone angle is 20 °, therefore circular crack lining cylindrical tube internal diameter is 360mm, and cone angle is 20 °.
The work process of the above-mentioned cyclone dust extractor setting up circular crack lining is as follows: gas-solid mixture is in high-speed condition
Inside lower entrance cyclone dust extractor, but the presence of circular crack lining, it is to avoid solid particle is to cyclone dust extractor device
The abrasion of wall.Band dust and gas are wandered about as a refugee in the presence of mental and physical efforts, carry out eddy flow, granule is larger inside cyclone dust extractor
Dust close to side wall, downward eddy flow then, however on circular crack lining circumferential weld presence, make near side wall
Downstream thicker solid particle is passed through ring circumferential weld, enter circular crack lining and cyclone dust extractor wall institute shape
In the annular space becoming, but the presence due to circular crack lining outer wall gusset, block the eddy flow of gas-solid mixture,
Make its descending flow rate attenuation, form low speed flow.The descending flow velocity of solid dust granule here in air-flow and from
Slowly fall under recast, the thicker solid dust of granule is excluded from underflow opening.The less solid particle of particle diameter
Little by centrifugal force, it is in rotary current center and moves upwards with air-flow, finally being discharged by overflow pipe becomes excessive
Stream.In the process, gas-solid mixture is directly contacted with circular crack lining, weares and teares, thus not removing to whirlwind
Dirt device wall causes to wear and tear.Although solid particle is contacted with circular crack lining, the presence of circumferential weld, near liner
Gas-solid mixture cannot form the air-flow of high-speed rotation all the time, thus significantly reducing the mill to circular crack lining
Damage, that is, improve the wearability of cyclone dust extractor, extend the service life of cyclone dust extractor.In addition, relatively
After coarse granule passes through circumferential weld to enter the annular space that circular crack lining and wall are formed under the action of the centrifugal force, only
Underflow opening exclusion can slowly be fallen through it may be difficult to back-mixing, in overflow air-flow, thus improves whirlwind and removes again
The efficiency of dust collection of dirt device.
