Description
Technical field
The present invention relates to a kind of dust catcher, a kind of portable dust collector based on cyclone dust removal principle, one kind can absorb big
Measure solid particulate matter and dust portable dedicated dust catcher, especially one kind in construction wall, roofing, ground or its
Its construction material is in the dust collector dedicated for cutting with being used in bruting process.
Background technology
Currently, portable dust collector mainly based on household dry type dust collector, is a kind of preposition filter bag or filter core dedusting
Dust catcher, basic principle are that dedusting filtering bag and filter core are installed before air-introduced machine, by filter bag and filter core by the ash in gas
Dirt and solid particulate matter are separated by filtration out, and filtered gas is discharged through wind turbine, complete dust and solid particulate matter and gas
Separation.
Other than household dry type dust collector, the portable dust collector sold currently on the market mainly also has straight-line dust suction wind
Machine deduster, Wet-dry dust catcher, industrial dust collector and carpenter's rotoclone collector etc..
Straight-line dust absorption fan deduster is a kind of dust catcher of postposition bag dust collector, and basic principle is in air inducing
Dedusting filtering bag is installed after machine, by filter bag by gas dust and solid particulate matter be separated by filtration out, complete dust and
The separation of solid particulate matter and gas.
Wet-dry dust catcher is to increase Moisture separation device on the basis of domestic vacuum cleaners, passes through special structure
Moisture in gas is separated, solid impurity in gas is then gone out by water-fast filter bag and filter element filtering again, water is realized, consolidates
The separation of body particulate matter and gas.To prevent motor from making moist, motor is damaged, while common electric machine is replaced with waterproof machine.
Industrial dust collector is then to strengthen the function of domestic vacuum cleaners or Wet-dry dust catcher, replaces bigger
The motor of power and the filtering filter bag, and more rational structure design of bigger etc., but there is no change for its basic principle.
Carpenter's rotoclone collector then uses different technological approaches completely, is a kind of dust catcher based on cyclone dust removal.
Its basic principle is that cyclone dust collectors are installed before air-introduced machine, and the sawdust carried in gas is isolated by cyclone dust collectors,
It because cyclone dust collectors can not be kept completely separate out sawdust, needs that dedusting filtering bag is installed after air-introduced machine, isolates remaining sawdust, it is complete
At the separation of sawdust and gas.
In construction, there are a large amount of cutting and polishing operation, the operation of metope fluting, wall plaster when such as hydropower installation
When polishing operation, the ceramic tile cutting operation etc. when ground and metope are laid with.It will produce a large amount of solid when such construction operation
Grain and dust, dust content and duration, far super household dry type dust collector, Wet-dry dust catcher and industrial suction
The permitted maximum operating mode of dirt device, the filter bag built in dust catcher are very easy to block, cause dust catcher suction to decline, cause with filter core
Dust catcher damages.Straight-line dust absorption fan when in use, then generates a large amount of particulate matter damage wind turbine because cutting with polishing
Impeller causes damage in impeller very serious, and needs very big postposition filter bag, therefore also cannot be satisfied construction needs.And
Carpenter's rotoclone collector can then occur the blocking of dust catcher inlet pipeline, cause whirlwind because of the excessive height of dust catcher import
The case where failure, dust catcher can not work, and cyclone dust collectors are poor to the separating effect of dust, whirlwind failure often occur
Situation.
Therefore, the dust catcher of the above several types cannot be satisfied such construction needs.
The separation principle of dust catcher can mainly have：Dedusting filtering bag filters (filter core) formula, water filtering type, cyclone filter formula, quiet
The combination of electric precipitation, gravity sedimentation type and inertial separation formula and two or more type.
The separating effect of dedusting filtering bag (filter core) is most preferably also the most frequently used, adjustable by the size for changing filter bag or filter core hole
The mass effect for saving filtering, the size by changing filter bag or filter core area are the efficiency of adjustable filtering, then in filter bag or
The side of filter core is collected the dust under filtering with particulate matter.Using micropore filter element, 99.99% diameter can be filtered out
The particle of 0.3um.But the hole of filter bag or filter core is easy to be blocked by dust and particulate matter, vacuum degree can decline, and lead to suction
Become smaller, increase dust collecting system resistance, reduce the filter effect of dust catcher, can not long time treatment big flow dust and particle
Object.Even after dust and particle content reduce, the ash for timely clearing up filter bag or cartridge surface attachment is still needed
Dirt, or the filter bag and filter core that more renew.
Water filtering is using air-flow when by water curtain or water mist, and most dust and particulate matter can all be dissolved locking
In water or forms larger particulate matter and detached, it is remaining again by further being filtered after filter, it is final to be discharged
The content of dust from gas and particulate matter when dust catcher substantially reduces.The filtering pick-up performance of vacuum cleaner with water filtering compares reason
Think, and the larger air-flow of dustiness can be handled.But since it uses water as filtration media so for product itself
Design and motor waterproofing protection more stringent requirements are proposed, price is relatively high, and needs to ensure water source when in use
The discharge of supply and waste water must carry out necessary cleaning etc. after being finished every time.
Cyclone filter (cyclone dust removal) is different with dust particles density using air, passes through rotating flow in dust-contained airflow
When road, under the action of the centrifugal force, wall is separated from air-flow and be trapped in dust, then so that grit is fallen by gravity
Bottom collection gets up, and the air-flow after separation is discharged from top.Cyclone filter is suitable for non-stickiness and non-fiber dust and particle
The removal of object, and the larger large flow-rate gas stream of dustiness can be handled.Cyclone filter can be used to remove 5 μ on dust removing effects
The particle of m or more, it is poor for the dust removing effects of 3 μm of particulate matters below.
Electrostatic precipitation is to make gas ionization using electrostatic field to make dust particles be adsorbed onto the collecting method on electrode.Contain
By being ionized when high-voltage electrostatic field, grit is combined negatively charged dust and gas body with anion, is put in anode surface under electric field action
Electricity and deposit.To purification gas or the useful grit of recycling in the industry such as metallurgy, chemistry.Air molecule is electric in highfield
From for cation and electronics, electronics, which marches on towards, encounters grit in anode process, the negatively charged anode that is adsorbed onto of grit is made to be collected.
Gravitational settling is different using the density of air and dust particles, by dusty gas by large space container after,
Gas flow rate reduces, and particulate matter falls downwards under the effect of gravity, is deposited in container bottom, realizes gas and dust
The separation of grain object.
Inertial separation is different with the inertia of dust particles using air, when dusty gas high speed passes through sharp turn, gas
Sharp turn can be passed through to continue to flow, and dust and solid particulate matter keep original path under effect of inertia, at sharp turn
The collection device of setting captures, and realizes the separation of dust and solid particulate matter and gas.
Invention content
In order to meet such construction needs, improves construction operation environment, reduce the discharge of solid particulate matter and dust, need
Design a kind of dust collector dedicated of absorbable a large amount of solid particulate matters and dust.The dust catcher problem to be solved mainly has：
1, solid particulate matter and dust content are very big in air-flow, and the duration is long, if using dedusting filtering bag and filter core mistake
Filter, then dust easily blocks dedusting filtering bag and filter core, causes the pick-up performance of dust catcher to be deteriorated, until that can not work；
2, the particle of part solid particulate matter is larger in air-flow, if dust catcher inlet height is higher, after working long hours, holds
Admission line is easily blocked, causes dust catcher that can not work；
3, the hardness of part solid particulate matter is higher in air-flow, and particulate matter diameter is relatively large, if being directly entered wind turbine, meeting
Fan brings very serious abrasion, and wind turbine is caused to damage；
4, the dust viscosity carried in air-flow is larger, and diameter is very small, is easily adhered in runner, barrier gas stream
Road；
5, it works after a period of time, filter bag inner wall can adhere to a large amount of dust, how quickly and effectively clear up filter bag inner wall
The dust of absorption improves the working effect of filter bag；
6, the interior dust collected of the rear dust collector that works long hours is more, how quickly to clear up internal dust, and be unable to shadow
Ring structure and the sealing etc. of dust catcher.
This invention address that a kind of device that can absorb a large amount of solid particulate matters and dust for a long time of design, solves building and applies
Working hour wall, roofing, ground or other construction materials generate a large amount of dusts with bruting process in cutting and pollute.It will be more than solution
On the basis of problem, the maintenance to dust catcher is reduced to the greatest extent, extend the service life of wind turbine, while providing temporarily for construction operation
The power supply of electricity consumption.Technical solution is used by the present invention solves above-mentioned technical problem：
1, the scheme being combined with filter bag dedusting using gravitational settling, inertial separation, cyclone dust removal in separation principle.Its
Basic principle is to provide enough negative pressure using high-speed centrifugal fan, suction inlet generate suction, will contain solid particulate matter with
The gas of dust enters pre- expansion chamber by pipeline and carries out inertial separation and gravitational settling, isolates that particle in gas is larger to be consolidated
Then body particulate matter enters back into cyclone dust collectors and completes secondary separation sedimentation, isolates the relatively small solid of particle in gas
Particulate matter and dust, twice sedimentation may separate out most solid particulate matter and dust, remaining dust in company with gas into
Enter centrifugal blower, is finally discharged into dedusting filtering bag by centrifugal blower outlet, further filters out the dust contained in gas, completed
The separation of solid particle and dust and gas.
2, it in the selection of cyclone dust collectors, abandons using single major diameter cyclone dust collectors, and uses multiple smaller straight
The cyclone dust collectors of diameter are in parallel, in the case where keeping fan delivery constant with wind pressure, improve cyclone dust collectors inlet gas
Speed reduces cyclone radius, improves the separating effect of cyclone dust collectors.Simultaneously as vortex diameter reduces, bring height into one
Step reduces, and advantageously reduces dust catcher height.
3, the content of solid particulate matter and dust is excessive in air-flow in order to prevent, causes cyclone dust collectors to fail, in dust-laden
Pre- expansion chamber is arranged before entering cyclone dust collectors in gas.Using inertial separation and sedimentation theory, allow larger in air-flow
Particulate matter settles in advance in pre- sedimentation interior, and tiny particles content and dust enter cyclone dust collectors and detached.

It is small, wind turbine can be directly entered.In order to avoid wind turbine damages, extend the service life of wind turbine, needs to increase draught fan impeller, spiral case
Antiwear characteristic improves the leakproofness etc. of bearing.
6, because using the cyclone dust removal of small diameter, the height of dust catcher import declines, and reduces dust catcher into one's intention as revealed in what one says
The risk of blockage.In addition to this, dust catcher import air hose need to be divided into two sections, the dust catcher close to dust catcher side is into one's intention as revealed in what one says
Pipe is using inner wall smooth, the general air hose of flexibility, it is therefore an objective to reduce the resistance of solid particulate matter and dust in wind Bottomhole pressure
Hinder, solves the problems, such as that dust catcher inlet pipeline is easy to block；Air hose close to suction inlet uses conventional dust catcher ripple air hose,
It is required that have higher flexibility, more convenient mobile air hose when to construct.
7, compared to particulate matter and dust content in dust suction gas, the particulate matter at fan outlet with dust content
It is substantially reduced, avoids the frequent jams of dedusting filtering bag.In view of the viscosity of dust is larger, tiny dust can be adsorbed on filter bag
Inner surface, influence the filter effect of dedusting filtering bag, therefore, need to by dedusting filtering bag inverted vertical be mounted on collection tray on, rely on
Wind pressure when blower fan work heaves filter bag, as collection tray shakes, the dust of filter bag inner wall is made to fall to bottom along inner wall
Collection tray is collected, and further improves the filter effect of dedusting filtering bag.After wind turbine is stopped, dedusting filtering bag is in the mistake fallen
Can also it play the role of to filter bag inner wall cleaning in journey.According to using effect, user can also have been carried with hand filter bag top into
Row shake, or filter bag is beaten when filter bag is heaved, the dust of filter bag inner wall is further cleared up, the filter effect of filter bag is improved.
8, there are 3 mutually independent decanting zones in this programme, can collect and store the particulate matter and dust isolated,
In the particulate matter collected at pre- expansion chamber and cyclone room two and amount of dust it is very big, collection at collection tray below dedusting filtering bag
Amount of dust it is less.Therefore, it is necessary to according to particulate matter volume corresponding with the design of the storage capacity of dust, and be arranged both can guarantee it is close
Envelope, and the constructional device that dust can be facilitated to topple over.
9, in view of dust has certain viscosity, the principle structural design of dust catcher at detachable, so as to and
