Embodiment Construction
[0069] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0070] Such as Figure 1 to Figure 33 As shown, this embodiment discloses a multi-disk thickener, including a pulp tank 100 and an upper cover 1 covering the pulp tank 100. A pulp inlet box connected to the overflow of the pulp tank 100 is provided on one side of the pulp tank 100. There is a central shaft 7 passing through the groove, on which the disks 2 are arranged axially, the disks are formed by combining fan-shaped plates and are disc-shaped, the fan-shaped plates are provided with filter screens, and the fan-shaped plates are formed The cavity is provided with a filtrate distribution valve 10 on the side of the shaft extension end of the central shaft 7, and the filtrate distribution valve 10 is installed outside the slurry tank 100 of the multi-disc thickener, and the outer circumference of the central shaft 7 is unifor...

The invention discloses a multi-disc thickener. The multi-disc thickener comprises a pulp tank body and an upper cover covering the pulp tank. A pulp feeding tank in overflow connection with the pulptank is arranged on one side of the pulp tank; a central shaft is arranged in the pulp tank in a penetrating manner; disks are arranged on the central shaft in the axial direction; and the disks are formed by combining fan-shaped plates and are in a disc shape. A filter screen is arranged on the fan-shaped plates; cavity channels are formed in the fan-shaped plates. A filtrate distribution valve is arranged on one side of the shaft extension end of the central shaft; the filtrate distribution valve is arranged outside the pulp tank of the multi-disc thickener. The upper cover is provided witha pulp stripping water pipe for stripping a pulp layer on the discs, and a continuous swing cleaning device used for cleaning the discs after pulp stripping. A discharging tank is arranged beside thediscs, filtrate flow channels are evenly distributed on the outer circumference of the center shaft, the filtrate flow channels are communicated with the fan-shaped plate cavity channels in the corresponding discs respectively, and outlets of the filtrate flow channels in the center shaft are guided to the filtrate distribution valve. According to the invention, the pulp concentration effect of the multi-disc thickener is comprehensively improved, and the working efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a multi-disk thickener. Background technique [0002] The multi-disc thickener is mainly used for thickening and washing the slurry of the pulp line. The slurry flows into the pulp box through the pulp inlet pipe, and then the pulp enters the pulp tank by overflowing. When the central shaft rotates, the fan-shaped plate on the disk (the disk is formed by combining fan-shaped plates and is disc-shaped) is immersed in the slurry under atmospheric pressure, and the slurry is separated by the filter medium, and a vacuum is gradually formed inside the water leg At this time, the slurry layer adsorbed on the surface of the fan-shaped plate is relatively thin, and a large amount of fine fibers and filler solids still exist in the filtered filtrate. The concentration of this part of the filtrate is relatively high, which is called turbid filtrate. As the fan-shaped plate c...
