Abstract

Multi-chamber air filtration unit. Optimal use of built-up space when connecting several units into larger units is achieved by a unit having a horizontal air outlet channel, through which the plane of symmetry of the filter unit passes, in which there is also an inlet channel, which consists of longitudinal louvers in the hopper space.

Description

(54) Multi-chamber air filter unit

Multi-chamber air filter unit. The optimum utilization of the built-up space when connecting several units into larger units is achieved by a unit having a horizontal air outlet channel through which the plane of symmetry of the filter unit, which also lies the inlet channel, which consists of longitudinal blinds.

FIG

0BR.2

BACKGROUND OF THE INVENTION The present invention relates to a multi-chamber air filter unit 6 by back-filter regeneration of the filter medium.

Known filter units designed to come out with a small built-in space and intended to eventually connect multiple filter units to clean any volumes of air with a single filter type have so far been built so that the interconnecting piping outside the filter unit outline is too close together and was the production and assembly pot # '.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a compact filter unit design which simplifies this connection and further reduces the built-up space and manufacturing effort.

According to the invention, this is achieved by a multi-chamber air filter unit with a regeneration of the filter substance by flushing, in which a plane of symmetry of the filter unit is guided through the horizontal air outlet channel of the cleaned air disposed between the opposite filter chambers.

This arrangement maximally utilizes the built-up space, on the one hand that at the same time one inner wall of the filter chamber forms at the same time the wall of the outlet duct of the cleaned air. or. with the input channels of each unit. The longitudinal blinds in the hopper have the function of a pre-separator, guide device and also a connecting channel.

An exemplary embodiment of the invention is shown in the accompanying drawings. Giant. 1 is a vertical cross-sectional view of the filter unit in a plane perpendicular to the symmetry plane of the unit; FIG. 2 is a sectional view of a group of three interconnected units in a plane parallel to the symmetry axis of the filter units;

FIG. 1 shows two opposing filter chambers 1 whose inner walls 2 are at the same time the vertical walls of the horizontal outlet channel J of the filter unit in each filter chamber J. The filter chamber 2 is arranged in the form of pockets, clean space, of the filter chamber J. it is detachable from the outlet duct 6 by the outlet flap 6 and the connection of the clean room to the flushing air inlet is made by the flush flap 2 · Soil hopper g results in an inlet 11 of dusty air having elongation in the longitudinal louvers 10. The interconnecting inlet duct g is parallel to the outlet duct g, the center of which is the plane of symmetry of the filter unit 1. According to FIGS. 2 and 3, the three filter units are interconnected by short connecting pieces 12 of outlet channels g and connecting pieces 13 of inlet channels g. pr In the operation of the filter, dusty air enters through the inlet H into the hopper g. a part of this air is fed through the gaps between the louvers 10 to the individual filter chambers 1 and the remaining air passes through the inlet channel 2 and the connecting piece. 13 additional filter units 1.

The cleaned air passes through the outlet flaps 6 into the interconnected outlet duct g. The flushing flaps 2 providing the flush air for regeneration of the filter member g are located on the filter chambers 1 parallel to the axis of the interconnected outlet duct g so that they are easily interconnected by a common pipe (not shown).
