Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Please see figure 1 , is a structural schematic diagram of a preferred embodiment of a smelting furnace according to the present invention. A smelting furnace includes: a furnace body 1 , a furnace roof 2 , an exhaust flue 3 , and a plurality of spray guns 4 .

[0031] Inside the furnace body 1 is a cavity 11 with an open upper end. The cavity 11 has a small diameter area 111 and a large diameter area 112 above the small diameter area 111. The small diameter area 111 and the large diameter area 112 have a circular cross section. , the inner diameter of the large diameter area 112 is larger than the inner diameter of the small diameter area 111 . Electronic waste, copper-containing mat...

Abstract

The invention provides a smelting furnace. The furnace comprises a furnace body and a plurality of spray guns, wherein a cavity with an open upper end is defined in the furnace body, the cavity is provided with a small-diameter area and a large-diameter area located above the small-diameter area, the inner diameter of the large-diameter area is larger than the inner diameter of the small-diameterarea, a discharge port and a plurality of spray gun ports are formed in the small-diameter area, and the plurality of spray gun ports are distributed at intervals along the circular cross section of the small-diameter area; and the spray guns are inserted into the spray gun ports, the plurality of spray guns deviate from the circle center of the circular cross section of the furnace body at the same angle in the same direction, the spray guns are arranged obliquely downwards relative to the horizontal direction, and the included angle between connection lines of the spray-blowing ends of the spray guns and the circle center of the circular cross section of the small-diameter area and the spray-blowing direction of the spray guns is 15 degrees. The smelting furnace has the advantages of lowenergy consumption, good smelting effect, and further being capable of reducing emission of harmful gas and avoiding environment pollution.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular to a melting furnace. Background technique [0002] Casting is a kind of metal thermal processing technology mastered by human beings earlier, with a history of about 6,000 years. China has entered the heyday of bronze castings between 1700 BC and 1000 BC, and the craftsmanship has reached a very high level. Casting is a method in which liquid metal is poured into a casting cavity adapted to the shape of the part, and after it is cooled and solidified, the part or blank is obtained. The material to be cast is mostly a metal that was originally solid but heated to a liquid state (eg copper, iron, aluminum, tin, lead, etc.), and the material of the mold can be sand, metal or even ceramics. Depending on the requirements, the methods used will vary. [0003] A relatively common problem in molten pool smelting metallurgical furnaces in the related art is that the materials f...
