Kiln device for producing glass, basalt fiber or rock wool

Abstract

The invention discloses a kiln device for producing glass, basalt fiber or rock wool. The kiln device comprises a kiln body, the kiln body is provided with a feed port, a flue gas discharge port and amolten liquid discharge port, the top of the kiln body is provided with a stock bin, and the outlet of the stock bin is communicated with the feed port; and a pre-melting tank and a homogenizing tankare arranged in the kiln body, the pre-melting tank right faces the feed port, the pre-melting tank is connected with the homogenizing tank through a boss, a first combustion spray gun is arranged above the pre-melting tank, and a second combustion spray gun is arranged above the homogenizing tank. Blocky raw materials are preheated and melted in the pre-melting tank, get over the boss, then flowinto the homogenizing tank, and are discharged out of the kiln from the molten liquid discharge port, and high-temperature flue gas generated by combustion flows through a raw material pile and is discharged through the flue gas discharge port. The device adopts the blocky raw materials as production raw materials, the blocky raw materials are directly fed into the kiln through the stock bin, andthe high-temperature flue gas in the kiln is fully utilized for preheating the blocky raw materials, so the energy consumption is low, and the waste gas emission is small.

Description

technical field [0001] The invention relates to the technical field of kilns, in particular to a kiln device for producing glass, basalt fiber or rock wool. Background technique [0002] At present, the production raw materials of industries such as rock wool, basalt fiber or glass basically use powder batching, and the batching materials are put into the kiln for melting through the feeder, which may easily cause the powder to fly and run out. At the same time, the kiln exhaust gas will take away part of the powder, which not only causes waste of production raw materials, but also blocks the flue during long-term production, and aggravates the erosion of the refractory material in the flue. There are also enterprises that adopt the pool kiln method for production, and the production raw materials are block raw materials, which are directly put into the kiln without preheating process, and the energy consumption is high. [0003] For kilns that produce rock wool, basalt fib...

Problems solved by technology

[0004] In order to solve the phenomenon that the powder material is used in the prior art, it is easy to cause the powder material to fly and run away. At the same time, the exhaust gas will take away a part of the powder material, which will not only waste raw materials, but also block the flue during long-term production, and aggravate the erosion of refractory materials; There is no preheating process in the kiln for feeding raw materials, and the energy consumption is high; the flue gas in the high temperature section is not recycled, resulting in the technical problem of low heat recovery efficiency of the flue gas. Cotton kiln device, which uses block raw materials as raw materials for production, directly puts block raw materials into the kiln through the silo, makes full use of high-temperature flue gas in the kiln to preheat block raw materials, and improves raw material preheating efficiency and flue gas heat recovery efficiency, reducing energy consumption and reducing exhaust emissions
