Filter device

Abstract

The invention relates to a filter device (104, 204, 304) for filtering granules, in particular moist and / or dry granules, comprising a filter housing (108, 208, 308) having a base (119, 219, 319), a cover (106, 206, 306) and a side wall (107, 207, 307), an inlet for the granulate arranged on the filter housing, an outlet (110, 210, 310) for the sieved granulate arranged on the filter housing (108,208, 308), a sieve (111, 211, 311) arranged in the sieve housing (108, 208, 308) and an inlet (116, 216, 316) for transfer air, wherein the outlet (110, 210, 310) for the sieved granulate, which is arranged on the sieve housing (108, 208, 308) is arranged on the side wall (107, 207, 307) of the sieve housing (108, 208, 308).

Description

technical field [0001] The invention relates to a screening device (Siebvorrichtung) for screening granular material (Granulat), especially wet and / or dry granular material (Siebvorrichtung), which comprises a screening housing with a bottom, a top cover and side walls; input opening (Eintrittsöffnung) for the granulate at the screening body; output opening (Austrittsöffnung) for the sieved granulate arranged at the screen housing; Opening (Einlassöffnung). Background technique [0002] Screening devices for pellets have long been state of the art, especially for screening processes in fluidized trains which follow wet granulation or drying processes. The known screening device is filled via an input opening for the pellets arranged at the top cover of the screening device, and after the screening process is filled via an output opening arranged in the bottom of the screening device behind a suction shoe (Saugschuh). emptying. In this case, the conveying of the pellets fr...

AI Technical Summary

Problems solved by technology

[0003] For such screening devices known from the prior art for pellets in which, for example, wet pellets are to be transferred to a dryer, it is disadvantageous that these screening devices have or require a large construction height, and It is therefore also necessary to provide a spatially feasible solution for implementing the method-technical installations equipped with known screening devices

Furthermore, it is disadvantageous in the known screening devices that due to the at least partially conical shape of the suction shoe of the screening housing of the known screening device, due to the conical formation of the particles adhering or depositing on the screening housing The product transfer of the screened pellets is clearly restricted in the area (suction boot)
