Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the invention, and that for a person skilled in the art, other drawings can be derived from them without inventive effort.

In describing embodiments of the present invention, the terms "longitudinal," "lateral," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and other terms are used in an orientation or positional relationship shown in the associated drawings for convenience in describing the invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the invention.

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, which are not repeated herein, but the present invention is not limited to the following embodiments.

Referring to fig. 1, the sealing device of the present invention includes a stationary ring 1 and a movable ring 2. This device is applicable to dustproof and the leak protection of retort drum-type cold charge machine feed inlet. Wherein, the static ring 1 is connected with the feeding pipe, and the dynamic ring 2 is arranged on the sealing head of the shell of the cooling machine. Thus, the stationary ring 1 remains stationary while the rotating ring 2 rotates with the cooler drum. The traditional sealing device adopts a labyrinth structure between a static ring and a moving ring to realize sealing, but conceivably, the combination of the static ring and the moving ring inevitably causes a gap between the moving ring and the static ring, and tiny dust still leaks from the gap. Therefore, according to the concept of the present invention, the sealing member 3 and the pressing ring 4 are additionally provided to replace the sealing form of the labyrinth structure, thereby preventing the leakage and the flying ash phenomenon to the maximum extent. Specifically, the sealing element 3 surrounds the outer side of the static ring 1, and the pressing ring 4 and the movable ring 2 are positioned on two sides of the sealing element 3 to press the sealing element. Like this, sealing member 3 has blocked the hole between quiet ring 1 and the rotating ring 2 to the material leakage of retort cylinder cold charge machine and the problem of ash are blown out have been solved.

In the present embodiment, the stationary ring 1 is cylindrical with both open top and bottom, and a seal plate 5 is provided at the left end in the view of fig. 1. The sealing plate 5 is used for connecting and sealing the static ring 1 and the feeding pipe. Therefore, as shown in fig. 2, the sealing plate 5 is provided with an oval-shaped coupling hole 8. Thus, the feed pipe can be inserted into the inner cavity of the material cooling machine through the connecting hole 8. Adopt welded fastening between quiet ring 1 and the inlet pipe to realize complete sealed, also fixed quiet ring 1 on the inlet pipe simultaneously. The movable ring 2 comprises a connecting part 6 and a blocking part 7, wherein the connecting part 6 is a circular flat plate, the blocking part 7 is cylindrical, and the blocking part 7 is vertically connected to the connecting part 6. The utility model discloses in, the whole diameter of stop part 7 should be greater than the inner ring diameter of connecting portion 6. In this way, a small annular area is reserved inside the connecting portion 6 for the sealing member 3 to abut against. If not so set up, can make the whole laminating of sealing member 3 on the cold burden machine casing, big frictional resistance can be brought for the rotation of cold burden machine cylinder to big area of contact like this, is unfavorable for the smooth and easy operation of cold burden machine. As shown in fig. 1, the connection portion 6 is integrally welded to the material cooler so that the rotating ring 2 can rotate with the material cooler drum. In the mounted state, the blocking portion 7 of the rotating ring 2 is just wrapped on the outer side of the sealing element 3, so that the sealing element is blocked and is prevented from loosening.

The compression ring 4 is in the shape of a circular plate and is used for tightly pushing the sealing element 3 against the movable ring 2, so that the sealing element 3 is fixed. It is understood that the contact area between the pressing ring 4 and the seal 3 is not too large, and a large frictional force is generated. To this end, the present invention takes the measure of vertically extending the inner edge of the pressing ring 4 to form a cylindrical extension section. The end of the extension section forms a conical surface with a conical bottom facing to the right. In this way, the pressure ring 4 contacts the seal 3 only through the end of its extension, as shown in fig. 1, thereby avoiding the generation of large friction forces. It can be seen from this connection that the width of the stop 7 of the rotating ring 2 should also be greater than the width of the seal 3, so as to also provide support for the end of the extension of the pressure ring 4. The utility model discloses in, clamping ring 4 passes through the bolt fastening on cold material machine to make the extension section of clamping ring 4 tightly push up sealing member 3 on connecting portion 6 of rotating ring 2. Of course, the mounting of the pressure ring 4 may also be in other known ways, such as welding or the like. However, the extrusion force applied by the pressing ring 4 to the sealing member 3 is not too large, otherwise, a large resistance is brought to the rotation of the cold material machine; however, if the pressing force is too small, the seal member 3 may be loosened, and thus a good sealing effect may not be obtained. The utility model discloses take bolted connection's mode then can adjust the extrusion force of clamping ring 4 through the adjusting bolt pretightning force very conveniently to can guarantee that sealing member 3 can not become flexible, can make cold burden machine operation itself smooth and easy again. Specifically, the utility model discloses set up bolt 9, corresponding, set up the mounting hole 10 that is used for making bolt 9 pass in the main part of clamping ring 4. Like this, can fix clamping ring 4 on the cold material machine through the bolt. Of course, in the embodiment shown in fig. 1, the connecting portion 6 of the rotating ring 2 has a large ring width, and therefore, a through hole for passing the bolt 10 should be correspondingly formed thereon.

The utility model discloses in, sealing member 3 can be cyclic annular or rope form to the cover is established or is twined in the quiet ring 1 outside. Synthesize the above-mentioned structural feature of the utility model can know, sealing member 3 need bear the friction of rotating ring 2 and clamping ring 4 in its both sides at operating condition, consequently this embodiment selects belted steel silk wear-resisting fiber ceramic sealing rope as sealing member 3. Therefore, the sealing device not only can ensure that the sealing device has a good sealing effect, but also can ensure that the friction bearing capacity of the sealing device is higher, thereby having a longer service life. In addition, since the seal member 3 is in a compressed state during operation, the single-layer seal member 3 is likely to cause failure of the sealing function and a reduction in life due to compression deformation. Therefore, it is preferable that the sealing material 3 is provided in two or more layers, and if a rope-shaped sealing material is used, the purpose of providing a plurality of layers can be achieved by winding a plurality of sealing strings or winding a long sealing string a plurality of times.

It can be known to synthesize above-mentioned structural description, and quiet ring 1, rotating ring 2 and clamping ring 4 three should set up with one heart, and these three can not take place to interfere when can guaranteeing the cold material machine operation like this. In addition, the stationary ring 1 is connected with a feeding pipe with higher temperature besides the friction, so the material of the stationary ring should be heat-resistant and wear-resistant stainless steel. The moving ring 2 and the compression ring 4 do not need to contact with a high-temperature feeding pipe, so that the moving ring and the compression ring can be made of common steel plates, but the moving ring and the compression ring also have the wear-resisting property. The utility model discloses a sealing device wholly is circularly, and its external diameter size should be according to the size setting of the feed inlet of cold charge machine. The utility model discloses in, sealing device's whole external diameter is 325mm-450mm, and this size can be applicable to the cold material machine of present all kinds of models basically.

The above description is only one embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
