RU2142398C1 - Self-lining trough - Google Patents

Abstract

FIELD: material handling facilities; loading and unloading of loose abrasive materials. SUBSTANCE: self-lining trough has bottom with edge protection members. Protection members are installed under trough bottom for axial displacement and arrangement of protective material layer on bottom at angle of friction slope. Protection members are made in form of rods. EFFECT: increased service life of trough and improved convenience in operation. 2 dwg

Description

 The invention relates to devices for loading and unloading bulk abrasive materials and can be used in mining, construction, metallurgical and other industries.

 Known self-lining tray - "pocket" containing the bottom and the protective elements of the bottom edge, and the protective elements are made in the form of hardfacing or lining.

 A disadvantage of the known solution is the short service life of the bottom edge of the tray, which quickly wears out by the flow of abrasive material. The restoration of the bottom edge is associated with downtime of technological equipment. Wear of the edge leads to a change in the position of the material flow and inaccurate loading.

 The objective of the invention is the creation of a self-lining tray with a long service life and convenient to use.

 The task is achieved by the fact that in a self-lining tray containing a bottom with edge protective elements, the protective elements are installed under the bottom with the possibility of axial movement and placement of the protective layer of material located on the bottom at an angle of repose.

 Another difference is that the protective elements are made in the form of rods.

 In FIG. 1 shows a self-lining tray in a section; in FIG. 2 is a view A of FIG. 1.

 The self-lining tray (channel, funnel, estrus) contains a bottom 1 with an edge 2. Under the bottom 1, protective elements 3 are installed with the possibility of axial movement, which can be made in the form of rods. The protective elements 3 are located in the guides 4 and are fastened, for example, with bolts 5. On the protective elements, a protective layer of material is located at an angle of repose.

 The tray works as follows.

 The transported material is located on the bottom 1, creating a protective layer, the surface of which forms an angle of repose with the horizon. The protective rods 3 are extended in front of the edge 2 of the bottom 1, and the material also lies on them, closing the edge. The transported material moves without touching the bottom 1 and its edge 1. During operation, the ends of the rods 3 wear out, but the wear is compensated by their extension along the guides 4. If necessary, the rods can extend at different distances, changing the direction of flow, for example, when a large piece gets onto the tray transported material. The extension of the rods 3 can be carried out without stopping the loading by acting on their non-working ends.

 The invention allows to create a self-lining tray with a long service life and convenient to use.
