Embodiment 1

[0040] A tumor remover is arranged on the bottom side of the rotary hearth furnace, and the tumor remover is arranged in the material distribution area and fixed on the furnace roof. The tumor remover can remove the tumor body stuck on the furnace bottom through the rotation of the helical blade, and the tumor body moves with the helical blade to the end of the helical blade, or falls off a small amount during the movement. There is a scraper on the debulking device, which can remove the material on the spiral blade. The tumor-discharging groove provided directly under the spiral blade is used to receive the tumor body falling from the spiral blade, and the tumor body is discharged from the rotary hearth furnace through the tumor-discharging port.

[0041] The height at both ends of the spiral blade is greater than that in the middle, so that the shape of the spiral blade matches the circumference of the furnace bottom. In this embodiment, the length of the rotating shaft is ...

Abstract

The invention discloses a rotary hearth furnace, which comprises a furnace body and a rotatable furnace bottom. The furnace body and the furnace bottom form an annular space, a tumor remover is provided on the side of the furnace bottom, and a tumor outlet is provided on the side wall of the furnace body; The tumor remover includes a spiral blade, a rotating shaft, a mounting frame, a scraper and a tumor removal groove; the spiral blade is located on the side of the furnace bottom; the spiral blade is fixed on the rotating shaft; the rotating shaft is rotatably installed on the mounting frame, and the mounting frame is fixed on the furnace body On the top of the furnace; one end of the scraper is fixedly connected to the installation frame, and the other end is located at the end of the spiral blade; the tumor outlet groove is located under the spiral blade; the tumor outlet groove is connected to the tumor outlet. The rotary hearth furnace of the present invention is provided with a tumor remover on the side of the furnace bottom to remove the bonded tumor on the furnace bottom to ensure the smooth progress of production.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a rotary hearth furnace capable of removing sticky lumps on the bottom of the furnace. Background technique [0002] With the application of various high-end electrical appliances, vehicles, and aerospace materials, non-ferrous metals have been developed and used in large quantities. While smelting non-ferrous metals, a large amount of non-ferrous metal slag is produced, and the non-ferrous metal slag is piled up in the storage plant to be processed. [0003] Among the various processes for treating waste slag at this stage, the most efficient and environmentally friendly treatment method is to treat waste slag in a rotary hearth furnace. Under the high temperature of the rotary hearth furnace, some molten substances often appear on the surface of the material layer. These substances have a low melting point, and when discharging from the rotary hear...
