Abstract
The invention discloses a sealing structure of a cover head of an inlet of a raw material grinding mill. The sealing structure of the cover head of the inlet of the raw material grinding mill comprises a raw material inlet, a raw material inlet cover, a first retainer ring, a first sealing ring, a second sealing ring, a plurality of bolts and springs, wherein the raw material inlet penetrates through the raw material inlet cover and the first sealing ring is arranged between the raw material inlet cover and the outer wall of the raw material inlet; the first retainer ring is arranged outside the raw material inlet cover and sleeves the raw material inlet; the first retainer ring is connected with the raw material inlet cover through the bolts; the second sealing ring is arranged between the first retainer ring and the raw material inlet cover; and each spring is arranged between the tip of the corresponding bolt and the first retainer ring. Through multilayered sealing, dust is prevented from entering the raw material grinding mill, meanwhile, abrasion of the sealing rings is avoided, the sealing effect is guaranteed, and equipment runs stably.
Description
Technical field
The present invention relates to raw material powder production technical field, especially raw material grinding mill entrance capouch seals structure.
Background technology
In use, its inlet shroud capouch place often occurs leaking ash phenomenon raw material grinding mill, directly influences bearing shell, causes that equipment cannot run well, frequently occur fault, adopts wool felt as sealing member at present, but wool felt easily weares and teares, it is impossible to ensure effective sealing.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is proposed to raw material grinding mill entrance capouch seals structure, by multi-layer sealed, it is to avoid the entrance of dust, more avoid the abrasion of sealing ring, it is ensured that sealing effectiveness so that equipment smooth operation simultaneously.
In order to realize foregoing invention purpose, the present invention provides techniques below scheme:
Raw material grinding mill entrance capouch seals structure, including feed(raw material)inlet, feed(raw material)inlet cover, the first back-up ring, the first sealing ring, the second sealing ring, bolt and spring,
Described feed(raw material)inlet is provided with described first sealing ring through described feed(raw material)inlet cover and described feed(raw material)inlet cover and described feed(raw material)inlet outer wall,
Described first back-up ring is arranged on the outside of described feed(raw material)inlet cover and is enclosed within outside described feed(raw material)inlet,
Described first back-up ring is connected with described feed(raw material)inlet cover by some bolts, is provided with described second sealing ring, is provided with described spring between described bolt end and described first back-up ring between described first back-up ring and described feed(raw material)inlet cover.
Further, also including the second back-up ring, described second back-up ring is arranged on cover inside, described feed(raw material)inlet and is enclosed within outside described feed(raw material)inlet, is provided with described second sealing ring between described second back-up ring and described feed(raw material)inlet cover.
Further, it is connected by described bolt between described first back-up ring with described second back-up ring, between another termination of described bolt and described second back-up ring, is provided with described spring.
Raw material grinding mill entrance capouch of the present invention seals structure, by multi-layer sealed, it is to avoid the entrance of dust, more avoids the abrasion of sealing ring, it is ensured that sealing effectiveness so that equipment smooth operation simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that raw material grinding mill entrance capouch of the present invention seals structure.
Detailed description of the invention
Describing the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, and protection scope of the present invention should not have any restriction effect.
Raw material grinding mill entrance capouch as shown in Figure 1 seals structure, including feed(raw material)inlet 8, feed(raw material)inlet cover 4, first back-up ring the 5, first sealing ring the 7, second sealing ring 3, bolt 6 and spring 1,
Feed(raw material)inlet 8 is covered 4 and is provided with the first sealing ring 7 feed(raw material)inlet cover 4 and feed(raw material)inlet 8 outer wall through feed(raw material)inlet,
First back-up ring 5 is arranged on the outside of feed(raw material)inlet cover 4 and is enclosed within outside, feed(raw material)inlet 8,
First back-up ring 5 covers 4 by some bolts 6 with feed(raw material)inlet and is connected, and covers at the first back-up ring 5 and feed(raw material)inlet and is provided with the second sealing ring 3 between 4, is provided with spring 1 between bolt end and the first back-up ring 5.
Also including the second back-up ring, the second back-up ring is arranged on feed(raw material)inlet cover 4 inside and is enclosed within outside, feed(raw material)inlet 8, covers at the second back-up ring and feed(raw material)inlet and is provided with the second sealing ring 3 between 4.
It is connected by bolt 6 between first back-up ring 5 and the second back-up ring, between another termination and the second back-up ring of bolt 6, is provided with spring 1.
Raw material grinding mill entrance capouch of the present invention seals structure, by multi-layer sealed, it is to avoid the entrance of dust, more avoids the abrasion of sealing ring, it is ensured that sealing effectiveness so that equipment smooth operation simultaneously.
