Description

The invention relates to metallurgy, in particular to sintering production, and can be used for storing sinter or other material (lime, fluxes, etc.), which decompose under the action of atmospheric moisture or long-term. storage.

A device for cooling agglomerate and pellets is known, which contains a tank with a flat bottom and a peripheral seal, a stationary vacuum chamber connected to the gas suction system 1.

However, this device does not allow long-term storage of material and is not suitable for replacement during operation.

Closest to the proposed software of the technical nature and the achieved result is a device for storing metallurgical raw materials containing a container with fins and a discharge hatch. All this is permanently combined with the trolley 2.

The disadvantage of such a device is the inability to preserve the quality of the material in it and the impossibility of its replacement during operation. This is so.

that storage and supply of such materials; agglomerate, agglomerate, lime, fluxes for welding and others in open containers does not exclude saturation of air with their moisture and, as a result, decomposition, the freezing of the raw material is not excluded in winter. The capacity in which they are stored and supplied to the consumer is inseparable from the trolley, which complicates the operation.

The purpose of the invention is to preserve the quality of the material, improve the operating conditions and create a replaceable device during its operation.

This goal is achieved by the fact that in the device containing a tank with ribs and a discharge hatch, the tank is made in the form of a closed bunker, with the outer and inner walls forming air cavities between themselves, and the discharge hatch is equipped with an adjustable gate.

Hermetically closed container with

25 walls of two coatings, between which there are air cavities, excludes contact of the raw material with air moisture I, condensation of moisture on the walls with which the material comes in contact, which preserves the quality of the latter. The location of the container on the supports and the elements for transferring it and installing it on the starting point greatly improves the operating conditions. FIG. 1 and 2 schematically depict a device in two projections with a notch along the wall; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one; in fig. 5 is a diagram of a possible device load; | In FIG. 6 - the position of the device during unloading. A device for storing metallurgical raw materials consists of a tank 1 with ribs 2. The tank is made in the form of a closed bunker equipped with hooks 3. The outer walls 4 and the inner walls 5 of the bunker are spaced from each other, forming a cavity 6 over the entire surface. a loading hatch 7 with a clamp 8. At the bottom of the tank there is a discharge hatch 9 with an adjustable gate 10 and its drive 11. The hatch is designed to mount a sleeve 12 on it. The capacitance is located on the base 13 to which the ladders are fixed and 14. On the walls of the device hooks 15 are installed. The device operates as follows. The device is fed to the place of production of sinter, lime, flux or other metallurgical raw materials. Opening hatch 7 (Fig. 4), the material is loaded into container 1. Then the hatch is closed and the device is mounted on the vehicle to be sent to the consumer. If several devices are installed simultaneously, they are fastened together with the help of hooks 15. For unloading at the consumer, the device is removed with the help of hooks 3 and mounted on a ramp (Fig. 5). With help from J 7. If flf / J 9 K

fat. 2 yes 11 open the gate 10 and through the pre-dressed on the hatch 9 sleeve 12 the raw material is unloaded. The technical and economic efficiency of the invention is achieved due to the double wall construction of the device. Raw materials (agglomerate, lime and fluxes) do not decompose under the action of moisture, do not freeze over in winter, do not lose their properties after its production. When using the proposed device, the quality of the material during long-term storage is preserved, the operating conditions are improved, since the raw materials are not only securely stored, but also conveniently delivered to the place of discharge. The design of the device ensures its operation in the conditions of metallurgical workshops without the payment of aglo-choppers. Claims of the device for storing metallurgical raw materials, containing a tank with ribs and a discharge hatch, characterized in that, in order to preserve the quality of the material, improve the operating conditions and the possibility of replacing the device during operation, the tank is made in the form of a closed hopper form between themselves air cavities, and the discharge hatch is equipped with adjustable. gated gate.
