On the polytetrafluorethylecoatings coatings of sintered plate filter core outer surface, with the increase of 12 surface area dust quantity of sintered plate filter core, dust and gas case 2
Pressure difference between Gas-cleaning box 3 increases, and control cabinet 5 can be made according to dust and gas by preset upper limit differential pressure value and lower limit pressure difference
Practical differential pressure value and default differential pressure value between case 2 and Gas-cleaning box 3 control the operation of wind turbine and pulse jet system.Example
Such as, practical differential pressure value is less than pre-determined lower limit differential pressure value, then controls fan operation, and pulse jet system is out of service；Such as fruit
Border differential pressure value is more than or equal to preset upper limit differential pressure value, then it is out of service to control wind turbine, and pulse jet system is run.It is optional
Ground can detect dust and gas case 2 and net according to the differential pressure measuring hole 11 for being respectively arranged at 3 both ends of dust and gas case 2 and Gas-cleaning box
Differential pressure between gas tank 3.If control cabinet 5 judges to need to enlighten to be arranged in Gas-cleaning box 3 according to preset upper limit differential pressure value
Pulse jet system carries out pulse backblowing deashing to sintered plate filter core 12, then opens the pulse jet system, make pulse gas
Sintered plate filter core 12 is blowed to by Gas-cleaning box side by injection tube 20, to which blowback falls to be gathered in the powder of 12 appearance of sintered plate filter core
Dirt, dust are first fallen under air-flow and gravity in ash bucket 19, and part dust therein is discharged into storage ash bucket 17, another part
Dust fall into is set in ash bucket 19 from applying in hopper 7, formed from coating 13, each pulse dust cleaning after circulation terminates,
Start for controlling the pulse valve 9 from coater, compressed air is sent into from painting hopper 7 by fluidisation pipe 8, certainly to agitation
Dust in coater 7 is applied to 12 table of sintered plate filter core by counter again after the part dust from flying under air-introduced machine suction function
It face can be under higher filtration velocity to realize to avoid fresh dust from directly being contacted with 12 surface of sintered plate filter core
Dust and gas is filtered, and since the presence from coating dust layer can also be further increased in the case where improving filtration velocity
Filter efficiency.Purified dust and gas passes through the discharges such as Gas-cleaning box 3, air-introduced machine 16 and air box 4.
By above technical scheme it is found that the utility model provides a kind of dust-extraction unit having from coater, for gold
Belong to dust and gas in laser processing procedure to purify.The dust-extraction unit includes bulky grain preseparator, dust and gas case, Gas-cleaning box, air box
And control cabinet, be provided in dust cleaning case for into dust and gas case sintered plate filter core provide from coating from coater, it is described from
Coater include be set in dust and gas case from apply hopper and with from apply hopper be connected to for from painting hopper in be passed through fluidisation
The fluidisation pipe of gas.Due to being provided in dust-extraction unit from coater, produced by can utilizing in metal laser process
Dust feature, i.e., generated fresh dust itself is relatively viscous in metal laser process, but is filtered by dust-extraction unit filter plate
The smaller feature of dust viscosity that core was trapped get off, by being applied to sintered plate by the dust being collected into is again counter from coater
The surface of filter core reduces the running resistance of system, dedusting dress to prevent fresh flue dust from directly being contacted with sintered plate filter core
The filtration velocity set can be improved by 0.9m/min to 1.1m/min.Ensureing that running resistance does not increase and filter efficiency does not reduce
