Embodiment Construction
[0041] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0042] like Figure 1 to Figure 12 As shown in the figure, this embodiment discloses a filtrate distribution device for a multi-disc thickener, including a central shaft 7 on which discs 2 are arranged in the axial direction. disc-shaped. A filter screen is arranged on the fan-shaped plate, and a cavity is formed in the fan-shaped plate. The filtrate distribution valve 10 is arranged on the side of the shaft extension end of the central shaft, and is installed outside the slurry tank 100 of the multi-disc thickener.
[0043] The central shaft 7 is a regular polygonal central shaft, including a conical mandrel 70, and a rotating shaft 73 fixed and penetrated by the central axis of the conical mandrel 70. The conical mandrel 70 is formed by the conical cylinder 71 and the axial direction of the conical cylinder 71. The sealing plates 72 at ...

The invention discloses a filtrate distribution device of a multi-disc thickener, comprising a central shaft, the outer circumference of the central shaft is evenly arranged with filtrate flow channels, and the filtrate distribution valve is arranged on the side of the shaft extension end of the central shaft and is installed on the side of the shaft extension end of the central shaft. Outside the slurry tank of the multi-disc thickener, the outlet of the filtrate flow channel leads to a filtrate distribution valve. The filtrate distribution valve includes a distribution valve housing, which is open on the side facing the slurry tank and is sealed and fixedly connected to the slurry tank. , so that the inner cavity of the distribution valve housing is connected with the filtrate flow channel of the central shaft; the inner cavity of the distribution valve housing is provided with a distribution sheet radially arranged along the central axis, and the radial length of the distribution sheet exceeds the filtrate flow passage on the central shaft, and the distribution The plate is connected with a distribution plate drive mechanism that drives it to rotate along the central axis; the lower part of the distribution valve shell is connected with two water legs arranged left and right, which are respectively the turbid filtrate water leg and the clear filtrate water leg, which respectively receive the water distributed by the distribution valve. Turbid filtrate and clear filtrate; the distribution plate rotates to adjust the distribution ratio of the filtrate leading to the two water legs. The present invention can improve the efficiency of filtrate distribution of the multi-disc concentrator.
Description
technical field [0001] The invention relates to the technical field of multi-disc thickeners in papermaking equipment, in particular to a filtrate distribution device of a multi-disc thickener. Background technique [0002] The multi-disc thickener is mainly used for the concentration and washing of slurry line slurry. The slurry flows into the slurry inlet box through the slurry inlet pipe, and then the slurry enters the slurry tank by overflowing. When the central shaft rotates, the fan-shaped plate on the disc (the disc is formed by the combination of fan-shaped plates and is in the shape of a disc) is immersed in the slurry under atmospheric pressure, and the separation of the slurry is realized 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 number of fine fibers and solids of the filler still exist in the filtered filtrate. The con...
