Description

Technical Field

[0001] The utility model relates to the technical field of ladle casting equipment, in particular to a ladle casting dust and mist absorption device. Background Art

[0002] Casting refers to the process of pouring molten metal into a specific mold for solidification. Generally speaking, casting is divided into two types: manual casting and automatic casting. The principle is to use a mold to pour liquid metal, and after the metal solidifies, a casting with a certain shape and size can be obtained.

[0003] Steel casting includes a ladle casting machine. When this automated casting equipment is casting, the high temperature will cause some substances to vaporize, thereby generating a large amount of dust and mist. In addition, these dust and mist often contain some toxic substances. Once these dust and mist gases cannot be collected and processed in a centralized manner, they will disperse and evaporate into the surrounding air, thus having a great impact on the environment.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 The ladle casting dust and mist absorption device comprises a support frame 1, a ladle hanging frame 2 is installed at the bottom of the support frame 1, a main air duct 3 is installed at the middle of the upper surface of the support frame 1, an auxiliary air duct 5 is arranged inside the ladle hanging frame 2, and side suction dust removal boxes 4 are symmetrically installed on both sides of the bottom of the ladle hanging frame 2, and the side suction dust removal boxes 4 on both sides are connected to the auxiliary air duct 5;

[0024] A top suction dust hood 21 is provided at the upper end of the ladle hoisting frame 2, and a second through hole 25 is opened on the upper end surface of the top suction dust hood 21. The main air duct 3 is installed on the upper surface of the second through hole 25 and is connected with the second through hole 25. The upper end of the auxiliary air duct 5 is arranged below the second through hole 25.

[0025] Among them, side protection plates 22 are symmetrically arranged on both sides of the ladle hoisting frame 2, connecting frames 23 are symmetrically arranged on the inner walls on both sides of the bottom of the ladle hoisting frame 2, and a reinforcing frame 24 is arranged on the upper end of the ladle hoisting frame 2 between the side protection plates 22 on both sides. The side protection plates 22 can play a certain protective role and can limit the leakage of dust and mist to a certain extent.

[0026] In addition, a first through hole 231 is opened on the upper surface of the connecting frame 23 , and a side suction dust removal box 4 is installed at the bottom end of the connecting frame 23 , so that the connecting frame 23 is convenient for installing the side suction dust removal box 4 .

[0027] Moreover, an auxiliary air duct 5 is provided at the upper end of the side suction dust removal box 4, and a plurality of dust suction holes 41 are provided on the surface of one side of the side suction dust removal box 4, and the dust suction holes 41 of the side suction dust removal boxes 4 on both sides are all facing the direction of the side suction dust removal box 4 on the other side. The dust suction holes 41 can use the suction force of the auxiliary air duct 5 to suck the dust mist generated during casting into the side suction dust removal box 4 through the dust suction holes 41, and then discharge it to the main air duct 3 through the auxiliary air duct 5.

[0028] Moreover, a secondary air duct 5 is provided at the first through hole 231 , and the first through hole 231 provides space for the secondary air duct 5 to pass through so as to be connected with the side suction dust removal box 4 .

[0029] In addition, a connecting plate 6 is provided on the upper surface of the top suction dust hood 21 and on the outside of the second through hole 25. The connecting plate 6 is assembled and connected to the support frame 1. The connecting plate 6 is used to connect to the support frame 1 so that the ladle hanging frame 2 can be installed and fixed on the bottom of the support frame 1. The connecting plate 6 is a prior art, which is a connecting flange. Its connection method is well known to people in the field of connecting flanges, and its specific installation method and structure do not need to be elaborated.

[0030] In the present embodiment, the support frame 1 is arranged above the ladle of the ladle casting machine, the ladle hanging frame 2 is adjusted to be connected with the ladle, and the other end of the main air duct 3 away from the top suction dust hood 21 is connected to the exhaust system. Then, in the actual production process, a large amount of dust and fog will be generated during the ladle casting production. At this time, the main air duct 3 generates suction through the exhaust system. At the same time, because the main pipe body at the upper end of the auxiliary air duct 5 is located below the main air duct 3, the auxiliary air duct 5 can also generate a certain suction force due to the suction force generated by the main air duct 3, so that after the two extended and forked pipe bodies below it are connected with the side suction dust removal box 4, the side suction dust removal boxes 4 on both sides can also generate a certain suction force.

[0031] Because the side suction dust removal box 4 is located at both sides of the ladle and the dust suction holes 41 are facing the ladle, when dust mist is generated during the casting process, the side suction dust removal box 4 can absorb most of the dust mist through the dust suction holes 41, and then the dust mist is sucked into the auxiliary air duct 5, and then drawn out by the main air duct 3, and discharged for subsequent waste gas recovery treatment.

[0032] However, since the suction force of the auxiliary air duct 5 is not as good as that of the main air duct 3, some dust mist that is not sucked into the side suction dust removal box 4, or the dust mist generated on the top of the ladle during the casting process, cannot be sucked into the side suction dust removal box 4, but due to the suction force generated by the upper main air duct 3, the dust mist will be gathered in the top suction dust removal hood 21 at the upper end, and then directly drawn out by the main air duct 3 for subsequent exhaust gas recovery treatment.

[0033] In the utility model, two side suction dust removal boxes 4 are provided at the bottom of the bottom end of the ladle hanging frame 2, which cooperate with the auxiliary air duct 5 to effectively absorb most of the dust and mist, thereby effectively solving the dust and mist generated by casting in the actual production process. The dust and mist generated on the top of the ladle during the casting process will also be extracted by the top suction dust removal hood 21 in cooperation with the main air duct 3 for subsequent waste gas recovery treatment, which can effectively filter the dust and mist generated by the casting process, thereby preventing it from polluting the environment.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
