Problems solved by technology
The following problems exist in the use of intermediate frequency electric furnaces: Nowadays, high temperatures are generated during the use of intermediate frequency electric furnaces. The body of the electric furnace will be damaged by the high temperature after long-term use. In severe cases, it will cause harm to the user. The use effect of the device is poor, and it cannot continuously cool down the electric furnace at a certain time interval
The invention with the patent number CN211120614U proposes an IGBT intermediate frequency electric furnace diversion device, which drives the fixed plate to move downward through the hydraulic cylinder at a certain interval, and the sliding plate is moved downwards under the action of the support wheel on the inner wall of the mounting frame during the movement of the fixed plate. The inner side moves, and then the sliding plate compresses the support spring, so that the openings of the first fitting port and the second fitting port are aligned, thereby starting the diversion effect. However, this invention can only conduct diversion cooling to the bottom of the intermediate frequency electric furnace, and cannot The outer side of the intermediate frequency electric furnace is effectively diverted to cool down, the cooling effect is obvious and the effect is poor, and the spring is used as the reset part. After the spring is used for a long time, the elastic force changes significantly, and the aging will affect the normal use of the device. lower sex

The invention discloses a diversion device for an IGBT intermediate frequency electric furnace, which includes a gear box, a diversion box and an electric furnace, the inner side of the diversion box is provided with a articulated rib, and a hanger is articulated on the articulated rib. The electric furnace is arranged on the top of the hanger, and the middle position of the top of the gear box is provided with an upper guide port, and the upper guide port communicates with the inside of the guide box, and the inside of the gear box is provided with an upper guide port. Interconnected upper draft tubes. By setting the diversion box, when in use, the electric furnace is placed on the hanger inside the diversion box. At this time, the electric furnace is in the middle of the inner side of the diversion box, and the outer side of the electric furnace is connected with the inner side of the diversion box. Compared with the traditional diversion device, the diversion range is more comprehensive, and the diversion cooling effect is effectively improved.
Description
technical field [0001] The invention relates to the technical field of electric furnace equipment, in particular to an IGBT intermediate frequency electric furnace diversion device. Background technique [0002] The intermediate frequency electric furnace is a power supply device that converts the power frequency 50HZ alternating current into the intermediate frequency (above 300HZ to 1000HZ). The intermediate frequency electric furnace heating device has the advantages of small size, light weight, high efficiency, excellent thermal processing quality and favorable environment. Coal furnaces, gas furnaces, oil furnaces and ordinary resistance furnaces are a new generation of metal heating equipment. There are the following problems in the use of intermediate frequency electric furnaces: Nowadays, high temperature will be generated during the use of intermediate frequency electric furnaces. If the electric furnace body is used for a long time, it will cause damage to the elec...
