    1434235 Cleaning rotary drum treatment apparatus BASF AG 9 July 1973 [10 July 1972] 32509/73 Heading F2N [Also in Divisions F4B and B1-B2] For removing or preventing the build up of incrustation adjacent an end wall 2 of a rotary cylindrical processing chamber 1 (e.g. a kiln, furnace, mixer or mill), a scraper 4-9, mounted on a freely rotatable hollow shaft 3, is located adjacent the wall 2 and eccentrically of the axis of cylindrical chamber 1. Product to be processed is introduced into the chamber by a feed pipe (not shown) inserted through the shaft 3. In use, frictional forces between the chamber walls and the scraper and/or between the product and the scraper cause the scraper to rotate at a lower speed than that of the chamber. The scraper may be cruciform, stellate, discshaped, serrated or annular, may be heated or cooled, and may scrape a region of the cylindrical wall of the chamber adjacent wall 2 as well as wall 2 itself.

    专利说明:

    The invention relates to the processing of products "which in the initial or intermediate state of a chemical or physical process are sticky or fusible even before transitioning to a solid final state, and can be used in the chemical industry in the processing and processing of melts, solutions, pastes or powders, which after Passing through the device becomes solid. By processing and processing it is to be understood in particular characteristic operations, for example, mixing, homogenizing, grinding, stirring, dispersing, dissolving, heating, cooling, drying, and the like. It is possible to carry out reactions, for example, between melts and gases, between melts and liquids, etc.
    A device for the continuous processing and processing of solid and / or liquid metal, containing a drum mounted for rotation and equipped with a loading or unloading device, and a scraper installed inside the bar 5 of the ban and interacting with its end wall 11].
    This device is used for processing concrete mixtures. Material is supplied through a screw auger, the tail of which is star-shaped. The screw auger is rigidly connected to the drum. The scrapers are mounted inside the drum on a spring-loaded pipe extending along almost the entire length of the drum. The scrapers do not rotate, but only press against the inner wall of the drum, freeing the wall from the accumulating 20 on it under the action of centrifugal forces of the material. The device is intended for the preparation of concrete, which during processing is not subjected to drying, i.e. material used
    927100 4 does not go from a liquid or pasty 1 state to a solid state. In this case, no sticking of products is observed, causing blocking of the drum mixer. Due to problems, this device cannot be used for this purpose.
    The purpose of the invention is the prevention of deposits on the end wall and in the space between the end and side walls.
    This goal is achieved by the fact that in the device containing the drum with a scraper interacting with its end wall, the Scraper is made star-shaped or disk-shaped and mounted eccentrically with respect to the longitudinal axis of the drum with the possibility of free rotation.
    In FIG. 1 shows a device for the continuous processing and processing of solid and / or liquid metal, 'in FIG. 2 - 25 hydrochloric scraper star-shaped axonometry.
    The device comprises a drum 1 of a cylindrical shape, at one end of which an end flange 2 is fixed. The hollow shaft 3 is mounted in the flange 3 {} using radial 4 and axial 5 bearings and is equipped with a scraper 6 located inside the drum. The scraper is made of star or disc-shaped, consisting of welded together of steel sheets, and installed ekstsen- en- 35 with respect to the longitudinal axis of the drum to be freely rotatable. Bearings 4 and 5 are sealed by Zimmer rings 7 and on the drum side by additional disk seals 8. The spline nut 9 provides axial tightening of the bearings. In addition, disc seals 10 prevent product from entering the annular gap 45 between the stationary loading device (not shown) and the hollow shaft
    3. The cylindrical drum 1 is driven by a sprocket 11 through a bearing housing 50 12 and an end flange 2.
    Devices "for continuous processing and processing of solid and / or liquid material works as follows. 55
    The drum is driven into rotation. The product is fed through a hollow shaft 3 .. In this case, the scraper is immersed in a drum filled with grinding media and product. Since in the proposed device the body of rotation can only move along a small part of the chamber, it is possible to protect the end wall of the loading device and the space between the end and side walls of the drum from sticking products, since the accumulating material does not find any support. In addition, the scraper operates on the end surface almost exclusively in the zone of the liquid phase with predominant liquid friction, as a result of which possible maximum dry friction loads can be avoided. Due to the fact that according to the invention, the scraper is mounted for rotation, it is introduced into the friction joint with the end flange through the introduced products, which causes various angular velocities of the moving parts. In this way, products accumulating in this place can be continuously removed without destruction and with the least power consumption.

    392 does not transfer from a liquid or paste-like state to a solid state. No sticking of the products is observed, causing blocking of the drum mixer. Due to problems, this device cannot be used for this purpose. The purpose of the invention is to prevent deposits on the end wall and in the space between the topside and side walls. I The goal is achieved by the fact that in a device containing a drum with a scraper interacting with its end wall, the scraper is star-shaped or disc-shaped and is set eccentrically with respect to the longitudinal axis of the drum with the possibility of free rotation. FIG. 1 shows a device for continuous processing and processing of solid and / or liquid metal, FIG. 2, a star-shaped scraper, axonometrics. The device contains a drum 1 of cylindrical shape, at one end of which an end flange 2 is fastened. A hollow shaft 3 is installed in the flange using a radial C and 5 axial bearings and is equipped with a scraper 6 placed inside the drum. The scraper is made of a star or disc-shaped, consisting of welded steel sheets, and is mounted eccentrically with respect to the longitudinal axis of the drum with the possibility of free rotation. Bearings 4 and 5 are sealed with Zimmer rings 7 and from the drum side with additional disk seals 8. The spline nut 9 provides axial tightening of the bearings. In addition, the disk seals 10 prevent the product from penetrating into the annular gap between the stationary loading device (not shown) and the hollow shaft 3. The cylindrical drum 1 drives with the sprocket 11 through the bearing housing 12 and the end flange

    3. At the same time, the scraper is immersed in a drum filled with grinding bodies and the product. Since in the proposed device the body of rotation can move only along a small part of the chamber, it is possible to protect the end wall of the loading device and the space between the end and side walls of the drum from sticking to the products, since the accumulating material does not find any support. In addition, the scraper works on the end surface practically only in the liquid phase zone with predominant liquid friction, as a result of which possible maximum loads of dry friction can be avoided. Due to the fact that the scraper is installed rotatably, it is in friction connection through the introduced products with an end flange that causes different angular speeds of moving parts. In this way, it is possible to continuously remove products accumulating in this place without destruction and with the least power consumption. Apparatus of the Invention A device for continuous processing and processing of solid and / or liquid material, comprising a drum mounted rotatably and provided with a loading or unloading device, and a scraper mounted inside the drum and interacting with its end wall, in order to prevent deposits on the end wall and in the space between the end and side walls, the scraper is made of a star or disc-shaped and set eccentrically with respect to the longitudinal axis of the baraba on with the possibility of free rotation.
