Hot aggregate bin capable of automatically receiving and feeding materials and hot aggregate tank matched with hot aggregate bin

Abstract

The invention discloses a hot aggregate bin capable of automatically receiving and feeding materials and a hot aggregate tank matched with the hot aggregate bin. The hot aggregate bin comprises an upper upright pole, an upper tank pressure-bearing platform, a balance weight automatic bin cover mechanism, a dustproof cover, a weighing module and a bin body. The hot aggregate tank matched with the hot aggregate bin comprises an insulation type tank cover, a hot aggregate tank body, a lug shaft, a guide pole, a bottom seal inverted bell and a bottom insulation steel cone structure. Because the bottom seal inverted bell and the guide pole of the hot aggregate tank can be matched with the upper upright pole and the upper tank pressure-bearing platform of the hot aggregate bin for opening the bottom of the hot aggregate tank for realizing a feeding function; meanwhile, after the feeding action is generated, the balance weight automatic bin cover mechanism can be opened under the gravity of the fed materials for realizing the receiving function. The whole feeding and receiving action is continuous, when hot materials in the hot aggregate tank are fed completely, the hot aggregate tank isempty, and the balance weight automatic bin cover mechanism of the hot aggregate is automatically opened, so that the automatic integration of feeding and receiving actions are realized. The invention has the advantages of high production efficiency, energy saving and no dust raising.

Description

technical field [0001] The invention relates to a charging device for an electric furnace, in particular to a heating bin and a matching heating tank of a submerged heat electric furnace. Background technique [0002] The traditional electric furnace smelting feed is a cold material feeding system, which uses a long conveyor belt and a ring feeder to realize the cold material feeding process; the disadvantage of the cold material feeding into the furnace is that the 500°C hot material after sintering needs to be cooled to room temperature before Entering the furnace of an electric furnace and then heating and smelting, this process has caused a considerable waste of energy and has been gradually eliminated by the market. [0003] At present, there is another hot material feeding process: through the elevated rotary kiln to the electric furnace feeding platform, and then unload the material from the kiln mouth into the thermal insulation tank on the feeding trolley, arrange t...

[0002] The traditional electric furnace smelting feed is a cold material feeding system, which uses a long conveyor belt and a ring feeder to realize the cold material feeding process; the disadvantage of the cold material feeding into the furnace is that the 500°C hot material after sintering needs to be cooled to room temperature before Entering the furnace of an electric furnace and then heating and smelting, this process has caused a considerable waste of energy and has been gradually eliminated by the market

The disadvantages of this process method are: ①This structure needs to set the hot material interface point completely on the feeding platform in the workshop. This method will inevitably increase the height of the civil workshop by more than 10 meters or even 20 meters or even 30 meters. Increased the cost of civil engineering, and the overall supporting equipment is bloated and complicated; ②In addition, the insulation bin cover on the platform is designed to be lifted and opened manually, which makes the production operation inconvenient; ③And there is a certain gap in the material tank feeding process It will inevitably cause a lot of ash, and in order to meet the environmental protection requirements, it is necessary to match the dust removal equipment

[0005] 1. It is not suitable for the feeding work before the high-level silo of the submerged heat electric furnace;

[0006] 2. This feeding method cannot realize 500°C hot material feeding;

[0008] 4. There is no dust removal and dust prevention treatment, and there are dust spots;

[0009] 5. Does not have heat preservation function

[0010] Using the hot material hoisting and transportation process can save energy, but there is currently no hot charging equipment that can realize the automatic feeding function. Therefore, a hot material bin that can adapt to the hot material hoisting and transportation process and realize the automatic integration of feeding and feeding is invented. And the supporting hot material tank has become a technical problem to be solved urgently
