Description

Technical Field

[0001] This utility model relates to the field of industrial dust treatment technology, and more specifically to a dust removal device for medium-frequency induction furnace casting. Background Technology

[0002] A medium-frequency induction furnace is a device that rectifies three-phase AC power into DC power, then converts the DC power into an adjustable current, which is supplied to the alternating current flowing through the capacitor and induction coil. This generates high-density magnetic lines of force in the induction coil, which cut through the metal material placed inside the coil, generating large eddy currents in the metal material. These eddy currents also have some properties of medium-frequency current, namely, the free electrons in the metal itself flowing in the resistive metal body generate heat. The medium-frequency induction furnace achieves metal heating through the principle of electromagnetic induction.

[0003] The shortcomings of existing technology are as follows: When medium-frequency induction furnaces are smelting metals, a large amount of smoke and dust will be generated due to oil, dust and impurities in the scrap metal. The smoke and dust are particularly serious during the spheroidization of cast iron. If no dust removal structure is set up, these smoke and dust will be directly emitted into the air. The particulate matter or harmful gases in the smoke and dust may pollute the surrounding environment and aggravate air pollution. At the same time, the inhalation of smoke and dust can cause irreversible damage to the human body and may cause respiratory diseases and other problems, reducing the practicality of the equipment and making it unfavorable for actual application and operation.

[0055] All sealing rings 67 are installed at the bottom of the cylinder 65, so that the sealing rings 67 are in contact with the top of the medium frequency induction furnace 2.

[0056] In practical application, the drive component 5 drives the lead screw 62 to rotate, and in conjunction with the slide rod 63, drives the cylinder 65 between the two sliders 64 to slide downward, so that the two sealing rings 67 at the bottom of the cylinder 65 come into contact with the top of the support plate 1, preventing dust from drifting out from the gap between the support plate 1 and the cylinder 65. Then, the filter plate 69 is inserted into the U-shaped groove 68 on the cylinder 65 to filter and purify the dust inside the cylinder 65, achieving the dust removal effect.
