FIG. 2 is a schematic side sectional view of the present invention;
fig. 3 is an enlarged schematic view of a portion a in fig. 2.
In the figure, 1-end cover, 2-sealing seat, 3-fan bearing, 4-groove and 5-sealing gasket.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1-3, a special sealing device for a carbon black fan comprises an end cover 1, a sealing seat 2 and a fan bearing 3; an end cover 1 and a sealing seat 2 are sequentially arranged on the fan bearing 3 from left to right, and the end cover 1 and the sealing seat 2 are detachably and fixedly connected through bolts; a plurality of grooves 4 are formed in the inner annular wall of the sealing seat 2 along the axial direction of the sealing seat 2; and a sealing gasket 5 is clamped in the groove 4. When the gasket is installed in the groove 4, a small amount of adhesive can be coated inside the groove 4, so that the gasket 5 is clamped in the groove 4 more firmly.
Further, in order to further improve the sealing effect, a felt strip may be annularly arranged on the inner annular wall of the sealing gasket 5; in particular, the felt strip may be fixedly connected to the sealing gasket 5 in advance by means of adhesion.
Further, the sealing gasket 5 is a silica gel gasket. The silica gel gasket has good flexibility, so that the silica gel gasket can be better attached to the groove 4, and a better sealing effect is obtained.
Further, the sealing gasket 5 is a polytetrafluoroethylene gasket. The polytetrafluoroethylene gasket has better acid resistance, alkali resistance and high temperature resistance. The silica gel gasket and the polytetrafluoroethylene gasket both have good weather resistance.
Further, in order to further improve the sealing effect, a plurality of grooves 4 are arranged at equal intervals.
During the use, will install seal gasket 5's seal receptacle 2 and end cover 1 cover on fan bearing 3 in recess 4, later with the bolt with end cover 1 and seal receptacle 2 fixed can.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
