Description
Technical field
The present invention relates to workshop dust collector technical fields, specially a kind of to add for shipyard welding, polishing and sandblasting etc.
The dust-extraction unit in work workshop.
Background technique
In recent years, the shipping industry in China achieves development at full speed, but the greenness in shipbuilding workshop still with
There is very big gap in developed country, and there are various pollution problems in entirely construction process, wherein dust pollution question is especially prominent
Out, a large amount of dust can be generated in welding, polishing and cutting process, dust pollution not only directly affects shipbuilding workshop
Operating environment, can also constitute a threat to the health of plant working personnel.So the dust pollution question in shipbuilding workshop must
It must cause enough attention.
Application No. is 201710339228.7 patents to disclose a kind of processing workshop dust-extraction unit, comprising: workbench, collection
Tracheae, metal hose, air-suction cover, cyclone separator, connecting tube, air-introduced machine.It will be pumped into negative pressure in gas collecting tube by air-introduced machine,
The dust of workbench vicinity enters metal hose from air-suction cover, then in gas collecting tube to cyclone separator, solid dirt
It falls to cyclone separator bottom and is discharged, gas is finally exported from air-introduced machine and is discharged.The device cannot to contain small density powder
The air of dirt carries out good purification, and gas collecting tube and air-introduced machine require manual cleaning, labor intensive object after long-play
Power is larger.
Application No. is 201420116083.6 patents to disclose a kind of industrial plant dust-extraction unit, including dusty gas is inhaled
Attached cover, dusty gas absorption sleeve, eddy flow pond and blower fan apparatus.Make to generate in dusty gas absorption sleeve using blower fan apparatus
Negative pressure, and then the air containing a large amount of dust and pernicious gas in workshop is made to enter inward turning flow cartridge by dusty gas adsorption cover,
Swirling eddy is formed after spiral board, swirling eddy makes the water rotation of dusty gas absorption sleeve bottom, the dust in air
In water with pernicious gas mixing, air is after preliminary purification by entering back into cyclone water after entering blower above outer sleeve
Pond.Gas circulating resistance is larger in the process of running for the device, and adsorbing powder dust object is easy to produce on the blade of blower, influences blower
Operating, increases the energy consumption of blower, and the structure of the device is excessively complicated, biggish noise can be generated in operation.

Specific embodiment
Following embodiment further illustrates the contents of the present invention, but should not be construed as limiting the invention.Without departing substantially from
In the case where essence of the present invention, to modification made by the method for the present invention, step or condition and replaces, belong to model of the invention
It encloses.
In order to mitigate the dust pollution degree of shipyard job shop, advanced optimizing plant working environment and ensure operation work
The health of human body of people, the present embodiment disclose a kind of shipyard processing workshop dust-extraction unit, in 5 upper end side of tangential double intake swirlers
Circumference is symmetrically arranged with two vacuum suck devices 1 on wall, and the vacuum suck device 1 is cut with tangential double 5 side walls of intake swirler
To connection and two vacuum suck devices 1 are arranged in parallel, in the connecting pin of vacuum suck device 1 and tangential double intake swirlers 5
Equipped with shut-off valve 2,1 outboard end of vacuum suck device is equipped with drain fluids entrance 7 and foul atmosphere suction inlet 8, and drain fluids enter
Mouth 7 is connect with compressed air interface, and compressed air interface is seen everywhere in shipyard workshop, therefore power source provides conveniently, is not necessarily to volume
Outer energy consumption.
The present invention is using tangential double intake swirlers, and when two shut-off valves 2 are all opened, this body structure determines rotation
The eddy flow field flowed in device is more excellent than the distribution of single entry cyclone.When processing Dust Capacity is less, one of cut-off can be closed
Valve 2 reduces unnecessary waste, increases the economy of device；Mutual backup, guarantee workshop are raw again for two vacuum suck devices 1
Dust-extraction unit can be run simultaneously always in the case of producing work ceaselessly, increase the reliability of device；In the embodiment of the present invention
The vacuum suck device that quantity is two is symmetrical arranged on cyclone side wall merely to carrying out to technical solution of the present invention straight
Detailed description is seen, the quantity of vacuum suck device is not to be regarded as being the limitation to technical solution of the present invention, can also expand certainly
Exhibition is tangential four entrance, and the present apparatus is with good expansibility.
Equidistant set that there are four high-pressure water mist component 3, high-pressure water mist groups in tangential double 5 top side wall ring weeks of intake swirler
Part by nozzle stainless steel nozzle core and stainless steel diversion blade and Anti-dripping device form, water is 20 kg-120 kg's
Under hydraulic pressure, flow at high speed forms a centrifugation vortex in guide vane, imperceptible open-core type droplet is sprayed from spray orifice,
High-pressure fog component is market ripe, is installed on tangential double intake swirlers using threaded connection.To increase powder
The density of dirt promotes dust that can preferably be separated, and the high-pressure water mist component 3 and tangential double intake swirlers 5 are tangential
Connection.
It is revolved at a high speed when dust is tangentially drawn into tangential double intake swirlers 5 by compressed air-driven vacuum suck device 1
After stream, by high-pressure water mist component 3, tangentially double 5 side walls of intake swirler tangentially spray into heavy pressure fine spray, and tangential spray into can
To prevent the influence to eddy flow field, adsorbing powder dust becomes larger in water mists, density later, and dust can be separated preferably, mentions
The separative efficiency for having risen dust improves air cleaning quality.Relative to some spray equipments, reduced using high-pressure water mist component
Waste to water resource also avoids the processing problem for the large amount of sewage that spray generates, therefore, dedusting disclosed in the present embodiment
The economy and practicability of device are stronger.
Clean air discharge pipe 4, bottom are equipped at the top of tangential double intake swirlers 5, and mouth and settling tank 6 are fallen by dust
It is connected, purified air is discharged by clean air discharge pipe 4, since the gas source of the equipment is compressed air, so directly
Discharge will not lead to the problem of secondary pollution, and the feature of environmental protection is good；Dust after separation then falls into settling tank 6 and is focused on.
The overall structure of dust-extraction unit disclosed in the present embodiment is simple, small in size, and operation is convenient, high dust collection efficiency, to straight
The dust that diameter is 50 microns or more has 85% ~ 98% removal rate, will not generate biggish noise, and nothing during the work time
Need to frequently be stopped work maintenance, and economy and practicability are all significantly improved.
Basic principles and main features and advantage of the invention have been shown and described above.But the foregoing is merely this hairs
Bright specific embodiment, technical characteristic of the invention are not limited thereto, and any those skilled in the art is not departing from this hair
The other embodiments obtained under bright technical solution should all cover within the scope of the patent of the present invention.
