DE4111031C2 - Dust collector - Google Patents

Description

The invention relates to a dust extractor for suction and Clean solid particles and / or droplets tendency gases, which verse with a filter medium working filter and a downstream one, security also provided with a filter medium filter and one below the working filter coaxial to the Dust outlet funnel of this working filter arranged, a tangential gas inlet and coaxial gas outlet has cyclone and dust extraction the funnel of the working filter the gas outlet of the Zy clones forms.

A deduster of the above type is the subject of DE 89 08 531 U1. With the deduster according to this script the safety filter is located above the work filters and at the same time above the pre-cleaning. The one All filter sides point in the same direction. Such dedusters are used either for cleaning Floors or other surfaces or for suction and cleaning of air from a dust-generating work area set. The space available for such Ent stauber is often low, so that one tries to to make them as compact as possible. This applies in particular especially if the deduster should be mobile. The Ver The size of a deduster is, however, narrow sets because with a reduction in the filter area the Time intervals between the required wiping cleaning intervals become undesirably short.  

DE 32 26 100 A1 already shows a deduster, where a cyclone as a pre-separator, a filter bag and a blower side by side in a common ge are arranged.

With a known congestion on the market ber is in the dust as a pre-separator behind the gas inlet outlet funnel of the working filter a baffle plate arranges so that coarse particles contained in the gas drop down into a dust collector and do not strain the filter medium. The security filter is in the well-known dust collector above the working file ters arranged.

The invention is based on the problem of congestion over the type mentioned in the beginning so that he builds as compactly as possible without the necessary wear and tear cleaning operations undesirably take place in quick succession have to.

According to the invention, this problem is solved in that the safety filter in the level of the working filter is ordered and that the inlet side of the security filters points in the same direction as the outlet side of the working filter.

Thanks to this design, the deduster has a low level Height because of the working filter and the safety Filter no longer as in the DE mentioned above 89 08 531 U1 are arranged one above the other.

The deduster is particularly compact, if the safety filter is above a fan of the Dust collector arranged spatially behind the working filter is.  

One does not need for the deduster according to the invention two different filter inserts, if according to another ren development of the invention of the safety filter with identical to the working filter and in a common fil terkammer is arranged with the working filter and the Inlet side of the security filter in the same direction tion points like the outlet side of the working filter. A such training enables a new filter to be installed first for the safety filter and then for to use the working filter.

Replacing the filter inserts is particularly easy, without this requiring a major constructive effort of the deduster if the safety filter and the working filter one behind the other in the fil terkammer are arranged, which at the front of the Dust collector a door to insert the security file ters and the working filter.

The dust extractor according to the invention can, thanks to its compact size be trained without difficulty and is also capable of delivering, for example, 15 sqm / min to still drive through usual doors when all of its Components on a wheeled support frame are arranged.

The invention permits numerous embodiments. For there is a further clarification of their basic principle of shown in the drawing and will be below wrote. This shows in

Fig. 1 is a partially cut side elevation view of the inventive dust extractor,

FIG. 2 shows a rear view of the dust collector according to FIG. 1.

Fig. 1 shows a support frame 1 , which carries all parts of the dust collector and is wheeled ausgebil det by wheels 2 , 3 . A cyclone 4 with a tangential gas inlet 5 and an axial gas outlet 6 is arranged in the front region of the support frame 1 . This gas outlet 6 leads coaxially into a dust outlet funnel 7 of an Ar filter 8 . This arrangement enables the dust from the working filter 8 to fall through the dust outlet funnel 7 and the cyclone 4 into a dust collecting container 9 detachably attached to a dust outlet 18 of the cyclone 4 during the cleaning process.

The working filter 8 is arranged together with an identical safety filter 10 in a common, horizontally extending filter chamber 11 which is closed at the front by a door 12 . Since the gas flows through the working filter 8 from bottom to top, there is the clean air side above its filter medium 13 . The flow through the safety filter 10 is exactly the opposite, from top to bottom. Its filter medium 14 must therefore be aligned so that its clean air side faces down. The clean air emerging from the safety filter passes via a line 15 into a blower 16 designed as a side channel compressor and leaves the deduster through a clean air outlet channel 17 .

For the cleaning of the working filter 8 is a blow pipe 19 , which telescopically extends upon exposure to compressed air and from above the working filter 8 with compressed air, so that the dust collected in it down through the dust outlet funnel 7 and the cyclone 4 in the dust collector 9 falls.

FIG. 2 illustrates in addition the design of the dust. It can be seen that the blower 16 has approximately the width of the safety filter 10 and thus also that of the working filter 8 that cannot be seen in FIG. 2. This makes the deduster as narrow as possible in width.
