[0035] In summary: the utility model proposes a medium frequency electric furnace that is easy to remove dust, the exhaust pipe 31 is clamped and fixed between the two sets of clamping plates 27, and one end of the exhaust pipe 31 extends to the inside of the medium frequency electric furnace body 1, and the diameter of the exhaust pipe 31 is the same as the diameter of the empty slot 23; when the medium frequency electric furnace body 1 is in use, the heat generated by the metal material will cause the generation of smoke, and the smoke will be discharged from the exhaust pipe 31 of the medium frequency electric furnace body 1, and the smoke will enter the filter chamber 32 along the exhaust pipe 31, and the smoke will be filtered through the filter plate component 35, and the dust and impurities in the smoke will be removed. The particles will remain on the filter screen component 35, and the cleaned gas will be discharged to the external environment through the square exhaust pipe 33. If the exhaust component 3 is used for a long time, the exhaust pipe 31 needs to be cleaned. The operator can turn the knob 22, and the knob 22 drives the first positive and negative screw rods 25 to rotate, and then the first positive and negative screw rods 25 will drive the two sets of movable plates 28 to move away from each other, and the two sets of limit plates 29 move away from each other along the long rod 26. At the same time, the two sets of clamping plates 27 move away from each other until the two sets of clamping plates 27 move away from each other and give up clamping the exhaust pipe 31. The exhaust pipe 31 is then removed from the main body 1 of the medium frequency furnace, which is convenient for users to clean and maintain the exhaust pipe 31 and prevent the exhaust pipe 31 from being blocked. If the exhaust pipe 31 needs to be reinstalled on the side of the medium frequency furnace body 1, the exhaust pipe 31 is inserted from the side of the empty slot 23. The exhaust pipe 31 passes through the installation cavity 21 and its end extends into the interior of the medium frequency furnace body 1. At the same time, the exhaust pipe 31 is between the two sets of splints 27. By turning the knob 22, the first forward and reverse screw rods 25 rotate in the opposite direction, and then the two sets of movable plates 28 and the two sets of clamping plates 27 move closer to each other, and the two sets of clamping plates 27 move closer to each other until the outer periphery of the exhaust pipe 31 is clamped and fixed, and then the exhaust pipe 31 is re-fixed on the side of the medium frequency electric furnace body 1 through the mounting assembly 2. This arrangement facilitates the disassembly and installation between the exhaust pipe 31 and the medium frequency electric furnace body 1 through the mounting assembly 2, and thus facilitates the user to clean and maintain the exhaust pipe 31 at any time, prevents blockage at the exhaust, and improves the service life of the device;
[0036] After using the exhaust assembly 3 for a long time, dust and impurities will accumulate on the filter panel component 35. In order to prevent the filter panel component 35 from being blocked, the user can replace the filter panel component 35 by rotating the rotating column 34 to rotate the second forward and reverse screw rods 37. The rotation of the second forward and reverse screw rods 37 will drive the two sets of block components 39 to move away from each other along the second forward and reverse screw rods 37. At the same time, the two sets of limiting slides 391 move away from each other along the fixing rod 38, so that the block component 39 moves away from the slot 351, and the slot 351 is engaged and separated from the block component 39. At this time, the user holds the handle component 36 and pulls the handle component 36 away from the filter chamber 32. The handle component 36 drives the filter panel component 35 to be pulled out from the installation cavity of the filter chamber 32, and then the filter panel component 35 is removed, which is convenient for the user to clean and maintain the filter panel component 35. The filter screen component 35 is then re-engaged in the filter chamber 32 by sliding the cleaned filter screen component 35 along one side of the installation cavity of the filter chamber 32 until the filter screen component 35 is re-slidably installed in the inner cavity of the filter chamber 32. At this time, the slot 351 corresponds to the position of the block component 39, and the filter screen component 35 is between the two groups of block components 39. The rotating column 34 is rotated in the opposite direction, and the reverse rotation of the second positive and negative screw rods 37 will drive the two groups of block components 39 to move closer to each other, and the block components 39 move toward the slot 351 until the two groups of block components 39 are re-engaged and connected with the two groups of slots 351, and then the filter screen component 35 is fixed inside the filter chamber 32. This arrangement can filter and purify the gas discharged from the medium frequency electric furnace body 1 through the filter screen component 35, and at the same time it is convenient for the user to clean and replace the filter screen component 35, which is simple to operate and improves the practicality of the device.
