Description
Technical Field
The utility model belongs to the casting field, concretely relates to side that is located intermediate frequency furnace side inhales formula activity dust absorption interface.
Background
The intermediate frequency furnace is a melting device commonly used in the casting industry, and along with the requirements of environmental protection and occupational health, a dust removal device is gradually installed on the intermediate frequency furnace for smelting molten metal. The focus of the dust removal technology is mainly focused on the selection of smelting and tapping liquid smoke trapping modes, and the size of the smoke trapping rate directly influences the working environment and physical and psychological health of steelmaking workers. The existing dust hood is generally arranged above the intermediate frequency furnace, and is in an umbrella-shaped structure, and negative pressure smoke dust suction or a rotary top suction hood is carried out from the upper side, or a dust removing mode of a one-way movable top suction hood is adopted. As the upper part of the intermediate frequency furnace belongs to the operation space for feeding or returning water, the operation space must be reserved. Therefore, the furnace needs to be moved away during the melting operation, and the furnace is rotated to the upper part of the intermediate frequency furnace after the operation is finished. The dust removal modes only solve the smoke pollution during the smelting of the intermediate frequency furnace and have no function on the dust pollution caused by the purification treatment operation or dumping of the molten steel. And the dust excluding hood that adopts among the prior art can not effectively be sucked a large amount of harmful smoke and dust that will produce in the short time, and the flue gas does not flow in the dust excluding hood in the short time, can do a group in the dust excluding hood cohesion, can not be disposed of fast, still has some dispersion in addition and causes atmosphere thermal pollution and dust pollution in the air, and the suction effect to the smoke and dust is not good.
Disclosure of Invention
For solving prior art's not enough, the utility model aims at providing an annular side suction type activity dust absorption interface of intermediate frequency furnace can realize that the intermediate frequency furnace smelts the dust removal under the prerequisite of guaranteeing the normal operation of intermediate frequency furnace, also can realize the discharge of smoke and dust when molten steel is handled or is emptyd.
The utility model aims at realizing through the following technical scheme:
the utility model provides an annular side suction type movable dust collection interface of an intermediate frequency furnace, which is characterized in that: this activity dust absorption interface includes: the air suction interface is connected with the communicating pipe through a flange; the air suction interface comprises a first guide plate, a second guide plate, an upper cover plate and a lower bottom plate, an opening is formed in one end of the first guide plate, the second guide plate, the upper cover plate and the lower bottom plate, the air suction interface is located above the side of the intermediate frequency furnace and perpendicular to a furnace platform of the intermediate frequency furnace, and the opening position of the air suction interface corresponds to the position of a furnace opening of the intermediate frequency furnace.
Furthermore, the first guide plate and the second guide plate are perpendicular to the lower bottom plate and are distributed in the radial direction, and the included angle is 60-90 degrees.
