Description

Multifunctional Electric Furnace Dust Removal Waste Heat Utilization Equipment

technical field

The invention relates to an electric furnace accessory, in particular to a multifunctional electric furnace dust removal waste heat utilization device.

Background technique

The electric furnace is a metallurgical furnace that uses the electrothermal effect to supply heat. It is widely used in the melting of metals. It mainly relies on the crucible in the furnace body to melt the metal. However, most of the existing electric furnaces are open when the metal is smelted. It will cause a large amount of heat to be discharged directly with the flue gas, resulting in waste of heat, and may burn the operator at the same time, bringing safety hazards to their personal safety.

Contents of the invention

The technical problem to be solved by the present invention is to provide a multifunctional electric furnace dust removal waste heat utilization device, which can fully utilize the waste heat, has a simple structure, and is safe and reliable.

In order to solve the above technical problems, the present invention adopts the following technical solutions:

A multi-functional electric furnace dust removal waste heat utilization equipment, including a furnace body, a crucible installed in the furnace body and brackets arranged on both sides of the furnace body. A drum is arranged horizontally, both sides of the drum are connected to the bracket through a rotating shaft, a drive motor is coaxially connected to the rotating shaft on one side of the drum, and a lifting groove matching the rotating shaft is provided on the side wall of the fume hood. A heat exchange pipe is arranged in a serpentine shape above the drum, and a smoke outlet pipe is arranged on the top of the smoke hood. A fume hood is connected by screws directly above the furnace body, and a roller is installed horizontally in the fume hood, so that the fume hood can be used to effectively avoid the direct discharge of the fume, thereby avoiding harm to the operator, safe and reliable. At the same time, the material to be smelted can be loaded into the drum through the feed port on the drum, and the waste heat of the flue gas can be used to preheat the material to facilitate the next step of smelting; The lifting groove is convenient for the movement of the fume hood. When it is necessary to feed or discharge materials into the drum, the fume hood can be moved directly, and the operation is simple; the heat exchange pipes are arranged in a serpentine shape above the drum, which is convenient. Further recycling of waste heat makes the waste heat recovery and utilization more thorough.

As a preference, spiral ribs are provided on the inner wall of the drum, which facilitates the axial movement of the material in the barrel and makes the preheating more uniform.

Preferably, the shape of the fume hood is a cuboid, which facilitates the installation and operation of the drum.

Preferably, a suspension ring is arranged on the top end of the fume hood, which is convenient for moving the fume hood.

Preferably, a filter screen is arranged in the smoke outlet pipe, which is convenient for filtering large particles of impurities in the smoke.

Compared with the prior art, the beneficial effect of the multi-functional electric furnace dust removal waste heat utilization equipment of the present invention is that by setting the preheating drum and the heat exchange pipe on the furnace body, the metal to be smelted can be effectively preheated, and more The waste heat can be recovered for various purposes, so as to achieve the effect of thorough utilization of waste heat, simple structure, safety and reliability.
