Description

(54) LINE FOR PREPARATION OF BULK MATERIALS. The invention relates to the metallurgical industry and can be used to prepare and supply bulk materials to the metal containers, including insulants. Devices for loading bulk materials are known, which contain hoppers, conveyors, feeders, and flj funnels. However, these devices do not allow thorough mixing of materials, unpacking, etc. The closest in technical essence and the achieved effect to the proposed is a device for introducing additives into the bucket. The device contains installed along the process of the bunker, feeders, closures, chutes, mixer, funnels located above the collector, vehicles 2. The drawbacks of the device are the lack of complex mechanization of the process and the poor quality of the preparation of materials. This is due to the fact that when the tare components arrive, their preparation is not mechanized and difficult to do in mass production, which reduces productivity. In this case, it is required to manually open the container, empty it, etc. For example, a homogeneous mixture (junkerite) containing% is necessary for filling powders into molds. coke 25, fireclay 30, bauxite H, ferrosilicon 3, powdered aluminum 28, supplied in a special container (metal cans). The purpose of the invention is the complex mechanization of labor and the improvement of the quality of material preparation. The goal is achieved by the fact that the known line includes bins, feeders, closures, chutes, mixer, funnels located above the collector, vehicles, sn (b) disintegrator and power components, transport elements of which through an additional bunker are combined with a common funnel connected to the loading chamber of the mixer, and the discharge chamber of the mixer is connected by conveyors to the bunkers of ready-made materials als, which estrus zakregteny over collector in contact with the distribution mechanism Figure 1 is a diagram offering emoy line; FIG. 2 is a view A of FIG. 1; in Fig, 3 section bb in Fig.2 (side); in fig. The k-node T in Fig. 1 Line for the preparation of bulk materials consists of bunkers 1 for storing components, at the base of which are mounted feeders 2 with crowns 3 located above collector k, made in the form of a closed skracovogo conveyor. The collection is connected to a common funnel 5. To unload the mechanical container (cans) with aluminum powder, a dispenser 6 is installed, consisting of a press 7 with knives 8. Under the press there are rails 9, on which trolley 10 and cassette I are installed, in which slots placed 12 banks with aluminum powder. The distance between the banks is equal to the distance between the knives of the press. In the line there is also an extractor 13 of tare components, made in the form of a power tilting device 1 with a cradle attached to it for placement in the last cassette with banks. A trolley with a shelter 15 and a lifting device 16 is located above the tilter. The bunker 17 and the closed conveyor 18 placed on them are located under the tilter. 22, an unloading chamber 23, which is connected by conveyors 2k to bunkers 25 of finished materials. Valves 26 and chutes 27 fixed above collector 28, made in the form of a closed conveyor, which funnels 29 are arranged for feeding materials, are installed under these bunkers. Pickups 30 of distribution trolley 31 located above the composition with molds 32 Self-unloading buckets 33 enter the line equipment complex. Lini works as follows. Using self-unloading buckets 33, materials (coke, fireclay, bauxite, etc.) are loaded into hoppers 1, Feeders 2 through funnels 3 and a collection of k bulk materials in the required proportions are fed into a common funnel 5 and through it into the loading chamber 21 of the mixer 22 Aluminum powder enters hermetically sealed cans 12, With the help of a lifting device 16, the banks are installed in the slots of the cassette 11 mounted on the trolley 10, the Cart moving along the rails 9 delivers the cans under the dispenser 6 "By turning on the press 7 using knives 8 sun ryvayuts lid cans 12. Thereafter the trolley is removed from the rastarivatel, the cassette with the banks using the lifting device 16 is removed and placed in the cradle tilting device 1, remover 13. Then the trolley 15 with the shelter: remover runs into and fixed thereon. By turning on the rotary actuator H, the cassette with cans is rotated 180 °. At the same time, aluminum powder from the cans is poured into the bunker 17, after which all devices are returned to their original position. Powder via conveyor 18 enters accumulative bunker 19 and from feeder 20 through the common funnel 5 into the feed chamber 21 of mixer 22. All components at The rotation of the drum blender 22 is thoroughly mixed and simultaneously transported to its unloading chamber 23, from which 3 bins 25 of finished materials for storage are fed by conveyors 2. As required, opening the gates 26, the finished material through chutes 27, collector 28, is loaded into the collecting tanks 30 of the distribution trolley 31 through the funnels 29. technological system for the preparation, preparation and backfilling of lyuikerite or other materials on the net, eliminates the use of manual labor, provides high-quality preparation of materials, the economic effect of introducing this invented per year in the order of 300 thousand rubles. Line's invention for the preparation of bulk materials for steel processing, containing hoppers, feeders, gates, chutes, mixer, funnels, vehicles located above the collection, characterized in that, for the purpose of comprehensive mechanization of labor and improving the quality of material preparation, unloading and extractor of tare components, the transport elements of which through an additional bunker are combined with a common funnel connected to the loading chamber of the mixer, and the discharge chamber of the mixer, inena conveyor with hopper 1 and finished materials, which are fixed on the heat collector by contacting .yuschim with distribution mehanyzmom.
