Abstract

The invention discloses a feeding sealing device for a wet ball mill, a sealing system and a mounting method of the sealing system. The device axially and sequentially comprises a jetting seat, a sealing gasket, a jetting body and a labyrinth pressure flange, wherein the jetting seat is fixedly connected onto a feeding pipe; the jetting body is connected with the jetting seat through a connecting piece; an annular cavity formed between the jetting body and the jetting seat is a current collecting chamber; the sealing gasket is connected between the jetting seat and the jetting body; the labyrinth pressure flange is sheathed at the end part of the jetting body; and at least two axial O-shaped sealing rings are connected between the labyrinth pressure flange and the jetting body. According to the feeding sealing device and the sealing system disclosed by the invention, a jet type noncontact sealing scheme adopted for a slurry part can realize a better mill head sealing effect; by use of triple sealing, zero leakage of the sealing device for a wet ball mill head is effectively guaranteed, and no leakage of a feeding pipe part of the mill head is realized; meanwhile, by means of the scheme, an original system is simply reformed with relatively-low expenses; healthy operation of equipment in a factory and the requirement of safe and civilized production can be met; and the scheme is easily popularized and applied to the wet ball mill.

Description

technical field [0001] The invention relates to wet ball mill equipment, in particular to a sealing device and an installation method thereof. Background technique [0002] In order to prevent the slurry in the mill from leaking from between the feed pipe and the spiral sleeve, the wet ball mill is generally sealed with a sealing gasket, such as figure 1 Shown: This sealing device is connected between the feed pipe 14 and the screw sleeve 15, see figure 2 As shown, it includes sealing gasket 16, gasket pressure flange 18 and gasket fastening bolt 17, which belongs to axial seal. The principle of this seal is to push the gasket pressure flange 18 by tightening the The gasket 16 is firmly pressed on the spiral sleeve 15, and the compressed sealing gasket 16 is filled in the inner hole of the spiral sleeve and the gap of the feed pipe to achieve the purpose of sealing. [0003] The main characteristics of this kind of seal are: it is suitable for static sealing, if it is use...
