Abstract

A multi-layer filter bag type filter is disclosed. An upper end cover and a lower end cover are fixedly connected to the upper end and the lower end of a cylinder body respectively, and the upper endcover and the lower end cover are connected with a feeding pipe and a discharging pipe respectively; an upper annular plate and a lower annular plate are fixedly connected to the upper part and the middle part in the barrel respectively; a first filtering mechanism and a second filtering mechanism are the same in structure and are each composed of a sleeve located on the upper portion and providedwith openings in the two ends and a filtering bag connected to the lower opening end of the sleeve, the upper end of the sleeve is externally fixed and connected with a flange plate, the first filtering mechanism is arranged in the upper annular plate and is fixedly connected with the upper annular plate through the flange plate in the first filtering mechanism; the second filtering mechanism isarranged in the lower annular plate and is fixedly connected with the lower annular plate through the flange plate in the second filtering mechanism; the lower end of the filter bag in the first filter mechanism extends into the sleeve in the second filter mechanism, and a steel filter screen is fixedly connected to the middle of the sleeve in the second filter mechanism. The filter is provided with double layers of filter bags, is ideal in filtering effect, and can meet the production requirements of high-standard slurry.

Description

technical field [0001] The invention belongs to the technical field of filtration, and in particular relates to a multi-layer filter bag filter. Background technique [0002] In the production process of color paste, coal water slurry and other slurry, filter devices are often used to remove impurities and large particle pigments to ensure the production quality and precision of products. This process usually uses bag filters, bag filters It is a pressure filter device, which is mainly composed of filter cylinder, filter bag and other main components. The existing filter bag type is usually provided with only one layer of filter bags. The filter structure of this structure is simple, the filtering effect is not ideal, and it cannot meet the production requirements of high-standard slurry. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a multi-layer filter bag filter, which has double-layer filter ...
