Combined dust-cleaning apparatus
The utility model relates to a kind of Combined dust-cleaning apparatus, especially a kind of dust arrester used for metal processing processing.
Can produce a large amount of dusts in metal processing processing procedure, dust has a strong impact on people's physical and mental health and safety, and therefore existing metal-working plant (as shot-blasting machine, polishing machine etc.) all is equipped with dust cleaning case to eliminate dust.Existing dust cleaning case comprises casing, blower fan, filter bag, ash bucket and dust sucting pipeline etc., and dust enters box house from dust sucting pipeline, falls into ash bucket after bag filtration after filtration.But the most volume ratio of the dust cleaning case of prior art is larger, and floor space is large, and heavy, be inconvenient to move; And existing dust cleaning case adopts filter bag or cyclone separator to carry out dedusting mostly, dust removing effects is not fine.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Combined dust-cleaning apparatus is provided, and can realize final dusting, good dedusting effect; And structure is intensive, modularization, and floor space is little, convenient mobile.
The technical scheme provided according to the utility model, described Combined dust-cleaning apparatus, comprise cyclone dust collectors, and the top of cyclone dust collectors arranges air inlet, and the bottom of cyclone dust collectors is connected with the first dedusting ash bin; It is characterized in that: the top vent of described cyclone dust collectors is communicated with the air inlet of dust-removing box by connecting airduct; The top of described dust-removing box forms toilet by baffle for separating, and the exhaust outlet of toilet is connected with blower fan, and lauter tub is installed in dust-removing box, and the dedusting mouth of dust-removing box bottom connects the second dedusting ash bin; Venturi tube is installed in upper end at described lauter tub, and the entrance point of Venturi tube is positioned at lauter tub inside, and the port of export of Venturi tube is arranged in toilet.
At described Venturi tube middle part, the blowback tracheae is set.
Described blowback tracheae is connected with the blowback pulse valve.
Described lauter tub is fixed in dust-removing box by tight fixed bolt and fixed head.
The lower end closed of described lauter tub, upper end open.
Combined dust-cleaning apparatus described in the utility model can be realized final dusting, good dedusting effect; And structure is intensive, modularization, and floor space is little, convenient mobile.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The K that Fig. 2 is Fig. 1 is to view.
The specific embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 ~ Fig. 2: as described in Combined dust-cleaning apparatus the first dedusting ash bin 1, cyclone dust collectors 2, air inlet 3, blower fan 4, blowback pulse valve 5, dust-removing box 6, Venturi tube 7, blowback tracheae 8, lauter tub 9, connect airduct 10, tight fixed bolt 11, fixed head 12, the second dedusting ash bin 13, dividing plate 14, toilet 15 etc.
As shown in Figure 1, the utility model comprises cyclone dust collectors 2, the top of cyclone dust collectors 2 arranges air inlet 3, and the bottom of cyclone dust collectors 2 is connected with the first dedusting ash bin 1, and the top vent of cyclone dust collectors 2 is communicated with the air inlet of dust-removing box 6 by connecting airduct 10; The top of described dust-removing box 6 is separated to form 15， toilet, toilet 15 exhaust outlet by dividing plate 14 is connected with blower fan 4, and lauter tub 9 is installed in dust-removing box 6, and the dedusting mouth of dust-removing box 6 bottoms connects the second dedusting ash bin 13; Described lauter tub 9 is fixed in dust-removing box 6 by tight fixed bolt 11 and fixed head 12, the lower end closed of lauter tub 9, upper end open, Venturi tube 7 is installed in upper end at lauter tub 9, the entrance point of Venturi tube 7 is positioned at lauter tub 9 inside, the port of export of Venturi tube 7 is arranged in toilet 15, at Venturi tube 7 middle parts, blowback tracheae 8 is set;
As shown in Figure 2, described blowback tracheae 8 is connected with blowback pulse valve 5, outside compressed gas source is connected with blowback pulse valve 5, the compressed air that provides blowback to use, for blowing to blowback tracheae 8, because be that pulse is interrupted blowback, so the piping and druming that is compressed air of filter cylinder discontinuity, shake off the dust on lauter tub surface, lauter tub 9 is regenerated, cleaned.
Operation principle of the present utility model: when work, the air inlet 3 on cyclone dust collectors 2 tops sucks the gas that contains dust, after carrying out dedusting for the first time by cyclone dust collectors 2, dust falls into the first dedusting ash bin 1 of cyclone dust collectors 2 bottoms, exhaust outlet through the gas after dedusting for the first time by cyclone dust collectors 2 enters in dust-removing box 6, lauter tub 9 in dust-removing box 6 is filtered, and realizes dedusting for the second time; Dust after the second dedusting falls into the second dedusting ash bin 13 of dust-removing box 6 bottoms, and the gas after dedusting is for the second time sucked the exhaust outlet at dust-removing box 6 tops by the Venturi tube 7 at lauter tub 9 tops, by blower fan 4, discharged.
When dust is attached to lauter tub 9 surperficial too much, can affect dust removing effects, now, blowback pulse valve 5 work that are connected with blowback tracheae 8, be blown into gas to blowback tracheae 8, gas by the inside of lauter tub 9 to flows outside, thereby play the effect to lauter tub 9 regeneration and cleaning.
