Description

Technical Field

[0001] This utility model relates to the field of induction furnace technology, specifically to a dust removal device for induction furnaces. Background Technology

[0002] An induction furnace is a furnace that uses electric current to generate heat to heat and melt iron. In a coreless induction furnace, the iron in the crucible generates an induced current under the action of an alternating magnetic field, which in turn generates heat, melting the iron itself and causing it to overheat. Over time, dust will accumulate on the induction circuit of the induction furnace, affecting its operation. Therefore, an induction furnace dust removal device is needed to clean the dust off the induction furnace.

[0003] Chinese utility model patent CN203758290U discloses a dust removal device for induction furnaces, relating to the technical field of induction furnaces. The device includes a suction pipe, an intermediate pipe, a base, a dust removal fan, and a filter. One end of the suction pipe has a suction port, and the other end is fixedly connected to the intermediate pipe and communicates with its inner cavity. The intermediate pipe, mounted on the base, is rotatably connected to the base with a vertical straight line as its rotation center. The inner cavity of the intermediate pipe is connected to the filter via a pipe. The dust removal fan is connected to both the inner cavity of the intermediate pipe and the filter via pipes. This dust removal device effectively removes most of the smoke and dust generated during the induction furnace smelting process and filters it out, reducing workshop smoke and dust, minimizing harm to human health, and reducing environmental pollution, thus contributing to environmental protection.

[0026] Example 1: Please refer to Figures 1-6The existing dust removal devices for induction furnaces are inconvenient to disassemble and assemble when maintenance is required. In order to solve this technical problem, this embodiment discloses the following technical contents;

[0027] A semi-ring plate 2 is fixedly connected to the upper rear side of the connecting pipe 1, and a stabilizing bolt 3 is connected through the upper left and right ends of the semi-ring plate 2. A dust removal device housing 4 is attached to the rear side of the connecting pipe 1, and a mounting ring plate 5 is fixedly connected to the outer rear side of the dust removal device housing 4. Several mounting holes 6 are opened at equal angles on the mounting ring plate 5. A semi-ring plate 2 is fixedly connected to the top front side of the dust removal device housing 4, and the dust removal device housing 4 and the semi-ring plate 2 on the connecting pipe 1 are fixed by the stabilizing bolt 3.

[0028] The dust removal device for induction furnace is divided into two parts: a connecting pipe 1 and a dust removal device. The rear top of the connecting pipe 1 and the front top of the dust removal device housing 4 are attached to the semi-ring plate 2. The two semi-ring plates 2 are fixed together by a stabilizing bolt 3, which fixes the connecting pipe 1 and the dust removal device housing 4 together. The dust removal device housing 4 is fixed to the plane by bolts passing through the mounting holes 6 on the rear mounting ring plate 5. The dust removal device housing 4 can be disassembled and assembled.

[0029] Example 2: Existing dust removal devices for induction furnaces easily accumulate dust, making cleaning difficult. Therefore, this example addresses this issue through the following technical solution: Figure 2 , Figure 4 and Figure 5 As shown;

[0030] A mesh plate 7 is fixedly connected to the rear end of the dust removal device housing 4, and a cross 8 is fixedly connected to the middle of the inner side of the dust removal device housing 4. The dust removal device body 9 is fixedly connected to the middle of the cross 8. The dust removal device body 9 is composed of a motor 901, a fan blade 902, a connecting rod 903, and a scraper 904. The motor 901 is fixedly connected to the middle of the rear side of the cross 8, and the output shaft of the motor 901 passes through the middle of the cross 8. The output shaft of the motor 901 is fixedly connected to the fan blade 902. The middle of the front side of the fan blade 902 is fixedly connected to the connecting rod 903, and the outer end of the front side of the connecting rod 903 is fixedly connected to the scraper 904. The rear side of the scraper 904 is in contact with the front side of the dustproof net 10. The dustproof net 10 is fixedly connected to the front side of the inner side of the dust removal device housing 4.

[0031] The output shaft of motor 901 drives fan blade 902 to rotate, and fan blade 902 drives scraper 904 to rotate, so that the dust removal device body 9 sucks dust into dust screen 10. The scraper 904 rotates to scrape off the dust adsorbed on the front side of dust screen 10, preventing dust from clogging dust screen 10.
