Embodiment Construction

[0046] Such as figure 1 The shown first embodiment of the sieve cleaner 1 ′ includes rocking feet which are not visible here. The rocking foot extends along the main axis A' of the sieve cleaner 1', which at the same time also forms the axis of the center of gravity. it is in accordance with Figure 5 to Figure 9 The swing foot 5 in the fourth embodiment of the present invention is formed in the same way.

[0047] Extending from the central region 10 ′ of the sieve cleaner 1 ′ are three cleaning elements designed as cleaning arms 6 ′, which are distributed uniformly around the center of gravity axis A′ in the circumferential direction. Each of said cleaning arms 6' comprises a respective cleaning zone 7'. Each of said cleaning zones 7' has a plurality of rectangular cleaning surfaces 8', which extend perpendicularly to the axis A' of the center of gravity and are respectively configured to surface-contact a screen surface not shown here (see for this Figure 10 , which sho...

Abstract

The invention relates to sieve cleaners (1) for cleaning a sieve surface (2) of a sieve box (3), which sieve box contains the sieve surface (2) and a sieve bottom (4). The sieve cleaners (1) contain a wobble foot (5), which extends along a main axis (A) of the sieve cleaner (1) and is designed in such a way that the wobble foot can be placed onto the sieve bottom (4) and that the sieve cleaner (1) can be tipped around the wobble foot (5); at least one cleaning element (6) having a cleaning region (7), wherein the or each cleaning region (7) has a plurality of cleaning surfaces (8) for cleaning the sieve surface (2). The cleaning surfaces (8) are each designed for at least linear contact with the sieve surface (2) and are separated from each other by slots (9) formed in the cleaning region (7). The invention further relates to sieve units and to methods for upgrading or converting a sieve box (3).

Description

technical field [0001] The invention relates to a screen cleaner for cleaning the screen surface of a screen box, the screen box comprising a screen surface and a screen bottom. In particular, such a sieve cleaner can be designed for cleaning the screen surface of the flat screen box. Furthermore, the invention relates to a screen unit and a method for improving or retrofitting a screen box. Background technique [0002] Movable sieve cleaners which can be placed on the screen bottom of the screen box and used to clean the screen surface of the screen box are known per se. Such sieves can be stacked and can be arranged, for example, in sieve stacks in flat sieves in order to separate or sieve granular to pulverulent products according to different fractions and masses. The sieve cleaner now receives the oscillating movement of the sieve and the sieve box and thus moves randomly around on the sieve floor, wherein they always bounce back on the sieve frame. [0003] A gener...
