Problems solved by technology

This traditional smelting process not only has a complicated process and a long production cycle, but also requires the construction of a large number of workshops and equipment in the two steps of remelting into melt in the smelting factory and remelting the metal ingot into melt in the foundry enterprise, which not only increases production input, but also consume a lot of energy, resulting in waste of energy
In short, due to the backwardness of production equipment and facilities, the traditional smelting process is not energy-saving and environmentally friendly; while the secondary melting of the traditional production mode produces secondary burning loss and energy consumption, which intensifies energy consumption, emissions and pollution
[0004] In the traditional smelting process, the crushed metal parts are directly added to the melting furnace. Due to the high temperature of the melting furnace, the normal temperature materials are added to the high temperature melting furnace, and the materials are heated from normal temperature to the melting state. A lot of heat, and the heating time is long; the temperature of the material rises instantaneously, it is easy to explode, the burning loss is large, and the quality of the melt is affected; while the combustion waste gas generated by the combustion of the melting furnace is directly discharged, the waste heat is not well utilized, and at the same time also pollute the environment
All of these have caused serious hidden dangers to product quality, energy saving and environmental protection.

Abstract

The invention provides a preheating device for non-ferrous metal smelting, which includes a support mechanism, at least one drum and a driving mechanism for driving the drum to rotate are installed on the support mechanism, both ends of the drum are closed, and a preheating chamber is formed inside the drum. One end of the drum is provided with a material inlet, and the other end is provided with a discharge port. The drum is also provided with a residual heat air inlet connected to the preheating chamber. The inner wall of the drum is obliquely provided with a plurality of scrapers. When the device drives the drum to rotate, the material to be heated in the drum moves toward the discharge port under the action of the scraper. The present invention preheats the material through the preheating device before smelting in the smelting furnace, reduces the temperature difference between the material and the smelting furnace, prevents the cooled material from exploding after entering the smelting furnace, improves the efficiency of smelting and reduces the temperature of the smelting furnace. combustion heating time.

Description

technical field [0001] The invention relates to the technical field of nonferrous metal smelting, in particular to a preheating device for nonferrous metal smelting. Background technique [0002] Casting is the process of pouring smelted metal liquid into the mold, cooling and solidifying to obtain the required shape and performance of the parts. Casting is a commonly used manufacturing method, with low manufacturing cost and high process flexibility. It can obtain complex shapes and large castings. It occupies a large proportion in mechanical manufacturing. The cast metals include: copper, iron, aluminum, tin, lead, etc. . [0003] Before the cast metal is formed into a casting, it must be smelted into a metal liquid or called a melt. At present, the production process of the metal melt obtained by the foundry industry in my country is as follows: 1. Prepare raw materials, including pure metals, recycled metals and others. Metals, etc.; 2. The smelting factory remelts raw ...
