IPC classes for russian patent Device for sealing a gap between the rotary kiln and a stationary camera (RU 2021566):
 Seal rotary kiln / 2018078
The invention relates to seals for rotary kilns and can be used in industry manufacture of building materials, ferrous and nonferrous metallurgy, cement production, limestone, lime, and other materials
 Seal rotary kiln / 2008595
The invention relates to the construction materials industry, in particular to a device for sealing a gap between the rotating and stationary parts of rotary kilns, drying drums
 Sealing device for rotating furnace / 2283996
Device comprises flexible casing whose one edge is secured to the unmovable chamber and the other edge is connected with the sealing ring. The edge of the sealing ring that faces the drum is made of two members that embrace the other contact ring from two sides. The contact ring is secured to the rotating drum. The device is provided with rollers mounted for permitting free rotation on the axles passing through the sealing ring.
 Screw for transportation of solid material with sealing structure and method for producing and utilization of reduced metal / 2299389
Drive shaft of solid substance feeding screw is extending within through openings provided within both side walls of heating furnace, and is held on liftable supporting devices positioned at both sides of furnace. Sealing structure has sealing blocks positioned outside the furnace on outer edges of through openings, said sealing blocks circumferentially surrounding said through openings, and movable shields equipped with openings for sliding of drive shaft for screw. Movable shields are brought into contact with sealing blocks through sealing members so as to be moved in vertical planes.
 Unit of sealing furnace worm shaft with granular materials / 2456521
Unit of sealing furnace worm shaft with granular materials contains screw 1, sealing bushing 2, whereby in the sealing area the shaft is equipped with sleeve 4 made of a high strength material and it has spiral grooves 6 with a polished surface and slopes 7 with angles of over 10 degrees on outer surface 5 in order to avoid self-blocking in the grooves of the granular material. The said sealing bushing 2 has grooves 10 with polished surface on internal surface 9 that are made capable of rotating in the direction opposite to the one of the shaft and slopes 11 with angles excluding a possibility of material self-blocking in the grooves whereby the shaft rotating direction ensures squirting of granular material 8 back into furnace 12.

(57) Abstract: Usage: in the technique of sealing of rotary kilns in the building materials industry. The essence of the invention: in the gap between the rotary kiln and a stationary camera placed elastic toroidal element made with a double layer winding the inner layer of the steel strip and located between the turns of the layer of metal mesh, asbestos, mint foil or other legkodeformiruemyh materials. By rotating the furnace to the toroidal element attached composite elastic shell of esestonskogo material from the group: Verado, steel. 1 C.p. f-crystals, 2 Il. The invention relates to techniques for sealing rotary kilns can be used in the building materials industry. Known seal rotary kiln, containing mounted in the gap between the rotary kiln and a stationary camera elastic toroidal element. A disadvantage of the known seals is the low efficiency of the seal due to the intake of air and low rabotosposobnosti due to rapid wear of the toroidal element. The aim of the invention is to increase the efficiency of the forward rotary kiln and a stationary camera; in Fig.2 - section a-a in Fig.1. Device for sealing a gap between the rotary kiln 1 and the stationary camera 2 has placed in the gap between the elastic toroidal element 3, which is made with two-layer winding the inner layer of the steel strip 4 and located between the turns of the layer 5 of metal mesh, asbestos, mint foil or other easily deformable material, which shape corresponds to the gap between the turns of the strip. By rotating the furnace to the toroidal element attached composite elastic shell 6 of the wear-resistant material from the group: Verado, steel. The gap between the camera 2 and the furnace 1 is determined depending on the beat of the axis of the furnace and its ovality. The diameter of the toroidal element 3 is determined from a condition of maintenance of contact with the rotary kiln 1, with a maximum possible gap between the microwave and the stationary camera 2. The thickness and width of the strip 4 is determined from the condition of winding of the toroidal element 3 and provide elastic deformation of its turns. Elastic shell 6 is integral with beveled ends to allow changes its diameter when the temperature change is institutional capacity. Device for sealing a gap between the rotary kiln and a stationary camera operates as follows. During the rotation of the furnace 1 toroidal element 3 is elastically deformed together with the strip 5, which provides a seal between the furnace 1 and toroidal element 3 band 5 or cowling 6. In the proposed design of the seal reduces the intake of cold air, which provides fuel economy. The presence of shell 6 provides increased service life, resulting in lower operating costs and reduced downtime. 1. DEVICE FOR SEALING a gap BETWEEN the ROTARY KILN AND a STATIONARY CHAMBER containing placed in the gap between the elastic toroidal element, characterized in that, with the aim of increasing effectiveness and efficiency, toroidal element is made with a double layer winding the inner layer of the steel strip and located between the turns of the layer of metal mesh, asbestos, mint foil. 2. The device under item 1, characterized in that it has attached to the toroidal element from rotating furnace and contacting the composite elastic shell of snooty the
