Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, this dust arrester 80 for being located in the prefabricated work station of a changeover portion, to filter the dust produced in air.The collecting chamber 85 that this dust arrester 80 comprises a housing 81, be located at a servomotor 82 on this housing 81 top, be located at silencing equipment 83 below this servomotor 82, be located at the filter 88 below this silencing equipment 83 and be located at below this filter 88.
The position of the corresponding filter 88 in side of described housing 81 is provided with a gas entrance 810.The position of the corresponding gas entrance 810 of inwall of this housing 81 is provided with a deflector 86.This deflector 86 is L shape steel plate, and it comprises vertically extending transverse slat 860 and the end upwards vertically extending stringer board 861 by this transverse slat 860 in the lower direction housing 81 by gas entrance 810.The upper end of described stringer board 861 is a little more than the upper end of gas entrance 810.
Described silencing equipment 83 comprises to be located in housing 81, and is positioned at one first dividing plate and a second partition of the below of servomotor 82.This first dividing plate and the upper and lower interval of second partition are arranged, and its inwall that is peripheral and housing 81 leans, thus forms an airtight outlet chamber 813 between inherent first dividing plate of housing 81 and second partition.The position of the corresponding outlet chamber 813 in side of this housing 81 offers a gas outlet 814.This second partition is provided with some through holes.The below of this second partition is provided with a centrifugal flabellum 87 be connected with servomotor 82, can drive centrifugal flabellum 87 constant speed rotary by servomotor 82.
One the 3rd dividing plate and the 4th dividing plate is respectively equipped with in the upper and lower both sides of filter 88 in described housing 81.The outer peripheral edge of the 3rd dividing plate and the 4th dividing plate is resisted against in the inwall of housing 81 respectively, thus between the 4th dividing plate, forms an airtight filter chamber 818 in the 3rd dividing plate.Two filters 88 are provided with side by side in this filter chamber 818.The position of the corresponding each filter 88 of described 3rd dividing plate is respectively equipped with steam vent.The position of the corresponding each filter 88 of described 4th dividing plate is respectively equipped with ash-hole.
Described filter 88 comprises the cartridge filter 880 vertically arranged and the reverse gas cleaning mechanism 881 be located in this cartridge filter 880.
Described cartridge filter 880 is cylindric filter cylinder, this cartridge filter 880 for gap be the fibre tube of 5-60 μm, its outer surface is provided with polytetrafluoroethylene film, most of sub-micron grit can be stopped, sub-micron grit filter material surface aggregation and form permeable dust-break cake, major part grit is blocked in barrel outer surface and can not enters inner barrel, can be eliminated timely and effectively under compressed-air actuated purging.This cartridge filter 880 has quite high filter efficiency, and more traditional filter material at least improves more than 3 ~ 5 times; And improve more than 2 times service life.
Described reverse gas cleaning mechanism 881 comprises the blowback magnetic valve 883 being positioned at cartridge filter 880 top and the pulse jet mechanism 885 be connected at below this blowback magnetic valve 883.Primordial Qi side and the pure qi (oxygen) side of described cartridge filter 880 are respectively equipped with a differential pressure pickup, the side that this Primordial Qi side and filtering gas enter, described pure qi (oxygen) side namely filter after gas side out.After filter 84 runs a period of time, trickle flue dust is adsorbed on cartridge filter 880 surface, the gas permeability of cartridge filter 880 is reduced, pressure difference signal is exported when the pressure reduction that differential pressure pickup detects exceedes a certain setting value, sequence starting blowback magnetic valve 883 after reverse gas cleaning mechanism 881 Received signal strength, clean compressed air is sprayed by the pulse jet mechanism 885 rotated, injection air-flow purges cylindrical shell until pressure reduction just stops lower than during another setting value, thus drop down onto in collecting chamber 85 after the micronic dust of cartridge filter 880 adsorption is eliminated under airflow function.
Described collecting chamber 85 comprises by the periphery of the 4th dividing plate to the conical section 850 of downward-extension and the drum-shaped section 851 being positioned at conical section 850 bottom.Described conical section 850 is extended in gradually-reducing shape downwards by the periphery of the 4th dividing plate.Described drum-shaped section 851 is by the end of conical section 850 to downward-extension, and its bottom end seal, for collecting the dust after being filtered by dust arrester.
When using this dust arrester 80, the extraneous gas from gas inlet port 810 with dust enters in filter chamber 818, owing to being provided with deflector 86 inside gas entrance 810, thus enter cartridge filter 880 after air-flow is upwards run, to prevent direct impact filtration cylinder 880.Enter into gas in filter chamber 818 by after cartridge filter 880, the particles such as the dust in it are fallen in collecting chamber 85 after being filtered cylinder 880 filtration and are collected, and clean gas is discharged outside to by gas outlet 814 by outlet chamber after being discharged by the top of cartridge filter 880 again.The dust accretions on cartridge filter 880 surface in this dust arrester 80 to a certain extent, is cleared up by reverse gas cleaning mechanism 881, more efficient compared to existing dust arrester.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
