When hot metal from a mixer car or other large movable hot metal container is distributed sequentially into each mold of a continuous pig iron casting machine to produce shaped pig iron, so-called "sea cucumber" one after another, the hot metal is supplied from a movable hot metal container. A hot water supply system is formed on the work floor by connecting a branching trough that guides distribution flow to each mold of the continuous pig iron casting machine to a receiving trough that receives the pig iron. When hot water supply actually starts, a large amount of dust and fume are generated and dispersed in the hot water supply system, which mainly consists of the movable hot metal container outlet, the pig iron receiving pipe, and the branch pipe, seriously damaging the surrounding environment. This significantly impairs the efficiency of operating the cast iron and associated crane operations. In order to improve this problem, a smoke collection hood described in Japanese Utility Model Publication No. 55-23727 has been proposed, but it has the following problems.

That is, as shown in FIG.
There is a gap between the movable hot metal container 1 and the movable hot metal container 1, and when the movable hot metal container 1 receives a cross wind, the soot and smoke generated from the hot water supply port 2 and the pig iron receiving gutter 6 of the movable hot metal container 1 cannot be completely collected, resulting in poor smoke collection efficiency. Furthermore, the soot and smoke generated from the hot water supply port 2 of the movable hot metal container 1 cannot be obtained with sufficient suction wind speed against the rising airflow due to the side suction method, and is scattered outside the smoke collection hood, worsening the surrounding working environment. was. In order to improve the adhesion between the side wall of the converter and the smoke collection hood,
In the lower edge of the movable hood, an iron plate brush made up of several iron plates is installed (Special Publication No. 36-3953), and in the dust collection hood of the hot metal charging ladle, there are rectangular thin plates on three sides other than the entrance path of the ladle. There are some with curtains installed (Special Publication No. 51-47415), but both have different shapes and
The structure is different, and it is difficult to apply it to a dust collector for a continuous iron casting machine, which is the object of the present invention.

The present invention is based on the prior art described above (Utility Model Publication No. 55-23727).
This is an improved dust collector for a continuous pig iron casting machine that supplies hot metal flow from the tilting of the movable hot metal container 1 to each mold 4 via the pig iron receiving gutter 6 and branch gutter 7 directly below. , the smoke collection hood 17 covers the hot water supply port 2 and the pig iron receiving trough 6 of the movable hot metal container 1 and has an exhaust port above, and the front part is opened by cutting out the hot metal melter 1 side to match the shape of the container. death,
A wire brush 13 is fixed to the notch, and a chain curtain 15 is suspended from the lower end of the smoke collecting hood 17 to form a three-sided smoke collecting hood 17, which is mounted on a gate-shaped movable trolley 8. It is an object of the present invention to provide a dust collector for a continuous pig iron casting machine, which improves the efficiency of collecting soot by bringing the soot and smoke into close contact with a movable hot metal container 1.

In order to make good use of the rising speed (approximately 5 to 8 m/s) of soot and smoke generated from the hot water supply port of the movable hot metal container and the top of the pigtail receiving gutter, an upward suction hood structure is adopted, and a movable hot metal container shape is installed on the side of the smoke collection hood. By attaching a wire brush made of the same adhesive material and making the smoke collection hood come into close contact with the movable hot metal container with the wire brush surface, the side opening area is reduced as much as possible. The interior of the hood can be seen through from the outside, and soot and smoke can be prevented from scattering due to cross winds flowing into the hood, thereby increasing dust collection efficiency.

The pigtail receiving trough 7 installed directly below is a branching trough that distributes the hot water received in the pigtail receiving trough to each mold 4. The smoke collection hood 17 of the present invention is installed so as to cover directly above the continuous pig iron casting machine 3 extending from the tap tap 2 through the pig iron receiving gutter 6 to the branching gutter 7, especially when moving the movable hot metal container 1 over the pig iron receiving equipment. It is mounted on a gate-shaped mobile cart 8 that moves forward and backward guided by rails 12 laid across the route. The smoke collection device of the present invention covers the hot water supply port 2 and the pig iron receiving trough 6 of the movable hot metal container 1, and provides an exhaust port 9 above.
In addition, the movable hot metal container 1 side is notched to match the shape of the container 1, and the front part is open. The wire brush 13 is fixed to the wire brush 13, the chain curtain 15 is hung and fixed to the end of the smoke collection hood 17, the fireproof material 16 is glued to the inner surface of the smoke collection hood 17, and the soot and smoke collected by the smoke collection hood 17 are collected. It consists of a movable exhaust duct 9 leading to the device 21 and a joint 23 connecting the movable exhaust duct 9 and the fixed exhaust duct 19. The movable hot metal container 1 is movable along its movement path, that is, the rail 24, and its hot water supply port 2 is connected to the pig iron receiving trough 6.
When attempting to start tilting by positioning the cart 8 directly above the
As shown in the figure, with the smoke collection hood 17 in close contact with the movable hot metal container 1, the movable hot metal container 1 is tilted and poured. At this time, the soot and smoke generated from the hot water supply port 2 and the pig iron receiving pipe 6 are transferred to the smoke collection hood 17 by the rising air.
After rising inside and reaching the upper exhaust port, the exhaust fan 2
The gas is sucked in by the vacuum pump 0, guided to the dust collector 21 via the movable exhaust duct 9 and the fixed exhaust duct 19, where the dust is collected, and then released into the atmosphere from the exhaust port 22 as clean gas. Pigle receiving gutter 6 and branch gutter 7 which are piglet receiving equipment
When replacing the molten metal, the pouring can be stopped, the motor 10 can be driven, and the gate-shaped mobile cart 8 can be moved to a place where it does not interfere with the operation of the crane.
