Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air collection device for deodorizing and exhausting smoke from a pouring line in a foundry.

Cast steel is often poured using a stopper-type ladle, and in order to collect the smoke generated at this time, it is necessary to collect the smoke throughout the entire pouring line, and the processing air volume is targeted at a certain degree of diffusion. This results in a huge amount of air.

Conventionally, in the pouring line using a return ladle, which is often used for cast iron, it is relatively common to install a hood a in the pouring line as shown in Figure 1 to increase the smoke collection efficiency (although this practice is common in casting steel In many cases, a ladle with a set of stoppers is used, and the ladle is moved by a crane, making it impossible to install a hood over the pouring line.

The present invention was made in view of the above circumstances, and its purpose is to provide an air collection device for a pouring line in a foundry that can greatly improve the efficiency of smoke collection and deodorization with a small amount of exhaust air. It's about doing.

Hereinafter, the present invention will be explained with reference to the drawings.

1 in the drawing is a casting line for cast steel, and this casting line 1
The line is roughly divided into a parallel line shown in FIG. 2 and an endless line shown in FIG. 3, but both types are equipped with a pouring zone 2.

An air collection hood 3 is provided in this pouring zone 2.

This air collection hood 3 is of a so-called accordion type, which is arch-shaped and expands and contracts in the axial direction.

A plurality of wheels 4 are provided at both lower ends of the air collection hood 3, and the wheels 4 rest on rails 5 laid in the pouring zone 2.

Further, a skirt 13 is attached to the lower end of the air collection hood 3, and the skirt 13 is grounded to ensure airtightness.

The skirt 13 is made of an elastic material such as rubber.

One of the wheels 4 is a drive wheel 6.

That is, the drive wheels 6 are connected to the prime mover 8 via the speed reduction mechanism 7.

A discharge protrusion 9 is provided at the center or rear end of the air collection hood 3, and the discharge protrusion 9 communicates with a dust collection and deodorization device (not shown).

In the drawing, 10 is a transport vehicle, 11 is a mold, and 12 is a ladle.

The mold 11 into which the metal has been poured from the ladle 12 moves in the direction of the arrow in the pouring zone 2. At this time, the drive wheels 6 are driven and the air collection hood 3 travels together with the mold 11. Shrink.

Then, smoke and odor generated after pouring are sucked in by driving the exhaust fan and flowed through the exhaust stack 9 to the dust collecting and deodorizing device.

As described in detail above, the present invention provides a plurality of wheels 4 at both lower ends of an arch-shaped air collection hood 30 that expands and contracts in the axial direction,
The wheels 4 are placed on the rails 5 that are softly cast into the pouring zone 2, and the skirts 1 are grounded to the lower ends of both sides of the air collection hood 30 to maintain airtightness.
3, one of the wheels 4 is a drive wheel 6 driven by a prime mover 8, and the air collection hood 3 is provided with an odor exhaust 9 leading to a dust collection and deodorization device. This is an air collection device for the hot water line.

Therefore, when the mold into which metal is poured from the ladle moves in the direction of the arrow in the pouring zone 2, the drive wheel 6 is driven and the air collection hood 3 travels and contracts with the mold, causing the dust collection and deodorizing device to move. Smoke and odor generated after pouring hot water by suction are eliminated9
Since more air is collected, the exhaust air volume can be reduced and the efficiency of smoke collection and deodorization can be greatly improved.

[Brief explanation of the drawing]

Fig. 1 is an explanatory diagram of the conventional air collection method in a pouring line, Fig. 2 is an explanatory diagram of a parallel type casting line equipped with an air collection device according to the present invention, and Fig. 3 is an explanatory diagram of the same endless type casting line. 4 is a side view of the air collection device according to the method of the present invention, and FIG. 5 is a sectional view taken along the line V--V in FIG. 4. 1 is the casting line, 2 is the pouring zone, and 3 is the air collection hood.

Claims (1)

[Claims] 1 A plurality of wheels 4 are provided at both lower ends of an arch-shaped air collection hood 30 that expands and contracts in the axial direction, and the wheels 4 are placed on rails 5 laid out in the pouring zone 2. A skirt 13 is installed to maintain airtightness when grounded, one of the wheels 4 is replaced by a drive wheel 6 driven by a prime mover 8, and an exhaust 9 is provided in the air collection hood 3 leading to a dust collection and deodorizing device.
