Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: with reference to fig. 1-4, a horizontal blendor bearing seal structure, including end plate 1 and axle 3, end plate 1 is located the blendor, be provided with transversal circular shape concave station 11 of personally submitting on end plate 1, concave station 11 middle part is provided with the shaft hole that holds axle 3 and pass through, still includes buckle closure 2, buckle closure 2 is located concave station 11, be provided with packing 4 in the buckle closure 2, packing 4 is the graphite packing, still includes gland 5 that can compress tightly packing 4 in the buckle closure 2, packing 4 is compressed tightly by gland 5 back and axle 3 in close contact with and then play the axial seal effect, gland 5 is connected with end plate 1 detachable. The snap cap 2 is compressed between the gland 5 and the recess 11.

The cross section of the buckle cover 2 is circular, a first cylinder wall 21 and a second cylinder wall 22 are arranged in the buckle cover 2, the inner diameter of the second cylinder wall 22 is larger than that of the first cylinder wall 21, the second cylinder wall and the first cylinder wall are connected through a conical surface 23, the conical surface 23 plays a transition role, and an annular plate 25 is arranged on one side, away from the second cylinder wall 22, of the first cylinder wall 21.

A first cylinder 52 and a second cylinder 54 are arranged on the gland 5, a groove 53 with a circular ring-shaped cross section is formed between the first cylinder 52 and the second cylinder 54, and the buckle cover 2 is positioned in the groove 53; the packing 4 is located at the first barrel wall 21 and two sides of the packing are respectively contacted with the end faces of the annular plate 25 and the second barrel 54.

The outer circumferential surface of the buckle cover 2 is provided with a guide strip 24, the inner side of the second cylinder 54 is provided with a guide groove 55, and the guide strip 24 is positioned in the guide groove 55, so that the structure can prevent the buckle cover 2 from rotating.

The gland 5 is provided with a first threaded hole 56 at the location of the recess 53.

The gland 5 is provided with a plurality of through holes 51, the end plate 1 is provided with a plurality of second threaded holes, and the first bolt 6 penetrates through the through holes 51 to be in threaded connection with the second threaded holes so as to fix the two together.

The working principle is as follows: when the packing 4 is damaged and the axial seal fails, the first bolt 6 is loosened, as shown in fig. 1, and then the gland 5 is pulled out to the left, so that the snap cap 2 is taken out together with the gland 5 with a high possibility, and when the snap cap 2 is difficult to be removed from the gland 5, the first threaded hole 56 is screwed by the bolt, so that the snap cap 2 is ejected. Then take off damaged packing 4, put new packing 4 in second section of thick bamboo wall 22 department (the external diameter of packing 4 equals the internal diameter of second section of thick bamboo wall 22 department, be provided with incision 41 on packing 4 so that overlap it in the outside of axle 3), then push buckle closure 2 right into concave station 11, later fix gland 5 on end plate 1 with first bolt 6, second drum 54 is pressed packing 4 in first section of thick bamboo wall 21 department in this process, because the internal diameter of first section of thick bamboo wall 21 is less than the internal diameter of second section of thick bamboo wall 22, packing 4 is inwards compressed, and with axle 3 in close contact with and then play the axial seal effect. Moreover, the second cylinder 54 is of a suitable length, and the distance between the end surface thereof and the annular plate 25 is smaller than the thickness of the packing 4, so that the packing 4 can be compressed in the thickness direction, and the axial sealing effect is further enhanced.
