Problems solved by technology

[0008] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a water-cooled movable hood for a horizontal side-blown converter (hereinafter referred to as a water-cooled movable hood), which solves the problem that the movable hood in the prior art is easy to protrude from the furnace mouth. The collision accident of metal adhesives on the shell of the converter, and in order to prevent the melt in the furnace from splashing on the adhesives on the movable fume hood from damaging the related equipment, the movable fume hood needs to be opened, so that the sudden increase of high concentration The problem of serious environmental pollution caused by SO2 flue gas escaping from the inner fixed hood

Embodiment 1

[0085] The water-cooled movable hood 4 in this embodiment is a front-side structure. details as follows:

[0086] Such as Figure 5 , Figure 6 , Figure 9 As shown, the water-cooled movable smoke hood 4 further includes: a water inlet pipe 430 , a water outlet pipe 431 , and a hose guard 434 are arranged on the smoke shield body 40 . Both the inlet pipe mouth of the water inlet pipe 430 and the water outlet pipe mouth of the water outlet pipe 431 are provided with nozzle flanges, and the two nozzle flanges are respectively arranged on the left and right sides of the cooling chamber, and are respectively used for communication flow. A first hose 432 for cooling water and a second hose 433 for cooling water out. In this embodiment, both the water inlet pipe 430 and the water outlet pipe 431 are steel pipes. The water inlet pipe 430 and the water outlet pipe 431 are respectively welded and fixed to the edge sealing plates 403 on the left and right sides of the smoke shield ...

Embodiment 2

[0094] The water-cooled movable hood 4 in this embodiment is a rear-side structure. The specific structure is as follows:

[0095] Such as Figure 13-Figure 16 As shown, in the specific structure of the present embodiment, the whole set of devices of the water-cooled movable fume hood 4 mainly includes:

[0096] The smoke hood body 40, the roller 41, the connecting ear 42 of the driving end, the water inlet steel pipe 430, and the water outlet steel pipe 431 of the rear side setting type are the same as those of the front side setting type, and the front and rear side setting types are the same. The circulation and cooling methods of cooling water in the water-cooled movable hood are also the same; in addition, the structure of the windshield assembly 44 of the water-cooled movable hood of the rear-side setting type and the front-side setting type is the same, and its structure refers to the first embodiment.

[0097] The difference between the rear side type and the front s...

Abstract

The invention discloses a water-cooling movable smoke hood of a horizontal side-blown converter. The water-cooling movable smoke hood comprises a smoke blocking hood body, a cooling chamber and a wind shielding assembly,and rollers are arranged on the left side and the right side of the smoke blocking hood body; the cooling chamber is arranged in the smoke blocking hood body, and the cooling chamber communicates with a first hose used for allowing cooling water to flow in and a second hose used for allowing the cooling water to flow out; a clearance channel is arranged on the side, facing the feeding port, of the smoke blocking hood body, a clearance opening is formed in the lower side face of the clearance channel, and when the feeding port is closed, the clearance channel surrounds the outer side of the feeding port; and the wind shielding assembly is arranged at the clearance opening of the smoke shielding hood body and is used for opening or closing the clearance opening. The water-cooling movable smoke hood disclosed by the invention is prevented from colliding with a metal bonding object which protrudes out of a converter shell at a converter mouth when the converter is rocked, so that the problem that the environment is seriously polluted due to the fact that high-concentration SO2 smoke which is suddenly increased escapes from an inner-layer fixed smoke hood as the movable smoke hood needs to be pulled open is solved.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, in particular to a water-cooled movable fume hood of a horizontal side-blown converter. Background technique [0002] Horizontal side-blown converter (also known as PS converter, hereinafter referred to as converter) is the main equipment for processing matte to obtain blister copper and low-nickel matte to obtain high-nickel matte in copper-nickel smelting. The converter process is mature and reliable, and the equipment and operation are simple. Stability, outstanding impurity removal ability, low investment and production costs, and strong ability to process cold material or scrap copper. At present, the converter is still the mainstream equipment used by copper-nickel smelters at home and abroad. However, when the converter is shaking (the furnace mouth is rotating between the blowing position and the feeding position during production), it is difficult to solve the environmental protect...
