SU1592050A1 - Drum for centrifugal separator - Google Patents

Description

The invention relates to a technique of centrifugal separation and can. be used in dairy, food, chemical and other industries. The goal is to increase productivity by increasing the duration

in-place operation and ease of sludge removal. The centrifugal separator drum includes a cover 1, a base with a cylindrical side wall 3, a plate holder 4 with a set of plates 5 mounted on it, forming a slurry space 6 with the side wall 3 of the base, and channels for supplying 7 raw materials and discharging 8 separated fractions. The drum is provided with an insert 9 installed in the slurry space 6. The latter consists of annular disks 10 arranged one above the other with a gap 11 along the side wall 3 of the base and vertical guides 12 attached to them. The inner surface of the annular disks 10 forms the outer surface of the package plates 5, the gap 13 for the passage of the fluid flow. 4 il.

The purpose of the invention is to increase productivity by increasing the duration of non-dismounting operation and simplifying the removal of sediment.

Fig. 1 shows schematically the proposed separator drum, a longitudinal section; figure 2 - node I in figure 1; on fig.Z insert, longitudinal section; figure 4 is the same, top view.

The centrifugal separator drum contains a cover 1, a base 2 with a cylindrical side wall 3, a plate holder 4 with a tray of plates 5 mounted on it, forming a slurry b with the side wall 3 of base 2, and channels 7 20 and 8 for supplying the initial product and supplying the separated fractions, respectively. The drum is provided with an insert 9 installed in the slurry space 6. The latter consists of annular disks 10, placed one above the other with a gap 11 along the side wall 3 of the base 2, and vertical guides 12 attached to them. At the same time, the inner surface of the annular disks 10 forms with the outer surface of the stack of plates 5, the gap 13 for. passage of fluid flow.

The drum centrifugal separator works as follows.

The initial product via channels 7 enters under the plate holder 4 and further into the package of plates 5, where it is separated. The separated fractions are discharged through channels 8. The sediment settles in the slurry space 6 in the gaps 11 between the inserts 9.

The gap 13 creates an additional hydraulic resistance to flow, which contributes to uniform loading of the stack of plates 5 in height. This, in turn, contributes to a more uniform filling of the sludge space 6 with sediment and thus increases the duration of non-selective work, which leads to an increase in the performance of the separator.

Due to the fact that there are gaps 11 between the annular discs 10, after removing the insert 9 from the drum with shaking, the precipitate falls out of the gaps 11, which simplifies its removal and shortens the time for inter-service maintenance.

Claims (1)
