Abstract

The utility model discloses an intermediate frequency furnace accident disposal pit. Paving gravel at the bottom of the accident treatment pit, designing a water collecting pit at the lowest point of the pit bottom, connecting the water collecting pit with an underground drainage system through a water outlet, and placing a filter screen at the connecting part of the water outlet and the water collecting pit; and a slag hopper is placed in the accident treatment pit, the slag hopper covers the accident treatment pit opening, a rib plate is welded on the outer surface of the slag hopper, and lifting lugs are symmetrically welded on two sides of the slag hopper. The utility model discloses simple structure does not have ponding, does not have molten steel explosion potential danger, and workman intensity of labour is little, and is on-the-spot clean and tidy.

Description

Accident treatment pit of intermediate frequency furnace

Technical Field

The utility model discloses be applied to the casting field, concretely relates to intermediate frequency furnace incident treatment hole.

Background

Accident treatment pits are designed in front of the intermediate frequency furnace, and in the process of melting the intermediate frequency furnace, if a sudden furnace leakage accident happens, molten steel in the furnace needs to be poured into the accident treatment pits immediately, so that the accident is prevented from being enlarged. Because the accident disposal pit is lower than the ground, a large amount of sundries and accumulated water often exist in the accident disposal pit. When the molten steel is poured under the condition that accumulated water exists in the accident treatment pit, secondary damage caused by explosion can occur, and the life safety of workers is threatened.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem be: the accident treatment pit of the intermediate frequency furnace is provided, molten steel can be poured conveniently and safely, and secondary accidents of molten steel explosion are avoided.

The utility model adopts the technical proposal that: paving gravel at the bottom of the accident treatment pit, designing a water collecting pit at the lowest point of the pit bottom, connecting the water collecting pit with an underground drainage system through a water outlet, and placing a filter screen at the connecting part of the water outlet and the water collecting pit; and a slag hopper is placed in the accident treatment pit, the slag hopper covers the accident treatment pit opening, a rib plate is welded on the outer surface of the slag hopper, and lifting lugs are symmetrically welded on two sides of the slag hopper.

The utility model has the advantages that: the utility model discloses simple structure does not have ponding, does not have molten steel explosion potential danger, and workman intensity of labour is little, and is on-the-spot clean and tidy.

Drawings

FIG. 1 is a schematic structural view of the present invention;

wherein: 1-slag bucket, 2-water outlet, 3-filter screen, 4-sump, 5-gravel, 6-rib plate and 7-lifting lug.

Detailed Description

Figure 1 bit the utility model discloses intermediate frequency furnace incident treatment hole structure schematic diagram paves gravel 5 in incident treatment hole bottom, and the minimum design has sump pit 4, and sump pit 4 passes through delivery port 2 and connects secret drainage system, has placed filter screen 3 at delivery port 2 and sump pit 4's the position of being connected, one prevents the loss of incident treatment hole bottom gravel 5, and two prevent that secret drainage system from blockking up. The slag bucket 1 is placed in the accident treatment pit, the slag bucket 1 covers the accident treatment pit opening completely, in order to reduce the weight of the slag bucket 1, the slag bucket 1 is formed by welding thin steel plates, and a plurality of thin steel plate rib plates 6 are welded outside the slag bucket 1 to increase the strength of the slag bucket and prevent deformation. Two lifting lugs 7 are symmetrically welded on two sides of the slag bucket 1, so that the slag bucket 1 can be conveniently lifted.

Under the general condition, ponding in the incident treatment hole comes from intermediate frequency furnace induction coil and leaks or ground clean water, the utility model discloses in the bottommost design sump pit 4 in the incident treatment hole, the induction coil leaks or ground clean water can infiltrate in gravel 5 flows into sump pit 4, and underground drainage system is discharged to water accessible delivery port 2 in the sump pit 4, like this, does not have ponding in the incident treatment hole, can not have the molten steel and promptly empty the explosion danger when going out of the stove.

The slag bucket 1 is not placed in an accident treatment pit under normal conditions, and is convenient for garbage cleaning, the slag bucket is placed in the accident treatment pit only when molten steel is treated through furnace disassembly, furnace beating and steel tapping, waste furnace lining materials and slag conglomeration agents fall into the slag bucket 1, and after work is completed, the slag bucket is lifted, garbage is poured into a vehicle and is transported out of a workshop. If a furnace leakage accident occurs before tapping, the molten steel needs to be poured, and the molten steel can also be directly poured into a slag hopper.

The utility model discloses simple structure, the management of being convenient for, workman intensity of labour is little, and is on-the-spot clean and tidy, no molten steel explosion potential danger.

Claims
