SU702226A1 - Arrangement for sealing the space between rotary kiln and stationary chamber - Google Patents

Description

-. 1 The invention relates to the equipment of furnace productions, and in particular to devices for sealing gaps between stationary and rotating parts of brick mills, and can be applied in ferrous and nonferrous metals production and in the production of building materials and in chemical industry. The known design of the sealing device, consisting of sectors, the gaps between the elements of which are sealed with spring-loaded wedges l. The drawback of the device is the unreliability of its operation under high temperature conditions due to the presence of springs and the complexity of the design. The closest to the technical result and the achieved result to the image is a device for sealing the gap between the rotary kiln and the movable chamber containing a contact ring rigidly fixed on the furnace body, an o-ring assembled from pie the furnace body ring, the fastening elements of the sealing ring to the non-submersible chamber, and the load tension device for crimping the sealing ring in the radial direction, while the tension ring (device About Bjji is combined, performing tension on the axial direction with mud: springs, and in the radial direction with the help of a tension load device ...., .....: ....... L ... b .: A disadvantage of the known device for sealing the gap between the rotary kiln and the fixed chamber is the unreliable gap between the sectors, the sector ring and the supporting metal structure, as well as the unreliable operation of the spring elements at high temperatures. The purpose of the invention is to increase the degree of sealing and reliability. This goal is achieved by the fact that the device for sealing the gap between the rotary kiln and the non-detachable chamber, the adjacent contact ring rigidly fixed on the furnace body, the control ring assembled from the graphite blocks of the sector mounted on the hull ring of the hull of the body, the fastening elements of the sealing ring to a fixed chamber and a cargo tensioner for crimping the sealing ring in the rascal direction, equipped with a set of segmented from graphite blocks a ring mounted on the contact ring of the furnace body, a wedge ring enclosing the sealing rings, the blocks of the sealing gauge facing the wedge bevels on the outer sides 1 pointing towards the circle of a friend and forming a ring groove of a kshnovo form in which the wedge ring is installed. In addition, the device can be equipped with a hopper, filled with fine fraction processing. material in which the sealing and wedge rings are placed. The essence of the invention is shown in the drawings. FIG. 1 shows a general view of a device for sealing the gap; in fig. 2 is a section along BB in FIG. one; in fig. 3 shows a section according to FIG. 2f in FIG. 4 shows a section along BB in FIG. 1. A device for sealing the gap between the rotating furnace 1 and the fixed chamber 2 contains sealing rings 3 of graphite, blocks mounted on the contact ring 4 of the furnace body 1 between the walls 5, 6, 7 and 8 of the bunker device with the bunker 9. rings 3 covers the wedge ring 10, which is crimped by cable 11. The cavity of the bunker device is filled with the fine fraction of the material being processed 12. The dotted line shows the mounting frame 13. Freight) It is a device 14 that presses the sealing rings 3 and the V-ring radial direction, - .. ,,.,. Upon mbntazh or dismantling of the sealing jrenbHbix a and the wedge 10 rings, after fixing the wall 7 on the mounting brackets 13, the wall 8 is removed and the bunker 9 is emptied of the fine fraction 12. The assembly is carried out in reverse order. The mounting brackets 13 are removed after fixing the wall 7 to the wall 8. During the operation of the seal, as a result of the unavoidable crushing drum of the furnace 1, the blocks of rings 3 and 10 are in constant oscillatory motion, which will help fill the gaps between the blocks of rings 3 and 10 with a fine fraction of the material being processed 12. Reliability of the seal will reduce the unorganized air into the furnace 1, which makes it possible to control the technological process. x Formula purchased 1. Device for sealing the gap between the rotary kiln and the setting; a sleeving chamber containing a contact ring rigidly fixed on the furnace body, an o-ring assembled from sector graphite blocks mounted on the contact ring of the furnace body, fastening elements of the sealing ring to the fixed chamber and a loading tensioner for crimping the full ring in the radial direction, characterized in that, in order to increase the degree of sealing and reliability of operation, it is provided with an additional seal, recruited from the sector graphite blocks, mounted on a contact ring, a scaffold housing, and a wedge ring that encloses sealing rings. Moreover, the sealing ring blocks are made with a wedge and bevels on the outer sides, directed towards each other and forming a wedge ring groove in which the wedge ring is installed. 2.ycTpoflcfep according to claim 1, characterized in that it is provided with a hopper filled with a fine fraction of the material being processed, in which sealing and wedge rings are placed. Sources of information taken into account for examination 1. U.S. Patent No. 3,575,337. / 263-32, 1971. 2. Application No. 2332072 / 29-33, incl. F 27 7/24 of 1976, according to which the decision was made to issue an author's certificate (prototype).
