[0007] 4. In the patent document JP7130909B2, it mainly considers how to control the ratio of the flue gas flow rates from the shunt dust removal pipe and the dust removal pipe through the flue gas regulating device to obtain the required flue gas mixture temperature, without considering the poor convenience of disassembly and assembly of the scanning module and the cumbersome maintenance problem during the process of smelting metal in the existing electric arc furnace.

[0021] Preferably, the usage method of this intelligent electric arc furnace is as follows:

[0022] S1. Before using this intelligent electric arc furnace, first fix the placement plate one on the furnace cover through the fitting of the plug rod and the jack one. Then start the electric push rod four on one of the support plates one. Then, driven by the connecting plate three, the baffle plate connected thereto moves upward, so that the baffle plate no longer blocks the material port. Then send the metal to be smelted into the interior of the electric arc furnace body through the material port.

[0023] S2. After sending the metal into the interior of the electric arc furnace body, start the servo motor in the support block to drive the reciprocating lead screw to rotate, so that the sliding sleeve moves up and down along the surface of the reciprocating lead screw. Then, driven by the placement plate two, the electric arc assembly can be inserted into the placement hole.

[0024] S3. During the process of smelting the metal, start the hydraulic push rod on the support plate two, and then push the connecting plate to drive the connecting rod to move, so that the placement plate three can rotate in the placement groove under the action of the plug block. Then drive the infrared scanner to scan the electric arc furnace body at different angles through the placement plate three to observe the metal smelting situation in the electric arc furnace body.

[0025] S4. After the smelting is completed, start the electric push rod four on the other support plate one. Then, driven by the connecting plate three, the baffle plate connected thereto moves upward, so that the baffle plate no longer blocks the liquid outlet. Then start the electric push rod five. Then, under the action of the shaft member, the arc-shaped rack one is pushed to move on the rack two through the bearing plate, so that the electric arc furnace body tilts to one side. Then pour out the liquid in the electric arc furnace body through the liquid outlet frame to improve the convenience of liquid discharge.

[0026] Preferably, in step S1, the following steps are further included:

[0027] S11. Then align the plug block on the placement plate three with the card slot, and move the placement plate three until the plug block moves into the jack two. Then release the placement plate three, so that it can drive the lower plug block to insert into the jack two under the action of gravity, so that the placement plate three can be limited in the placement groove.

[0028] In step S2, the following steps are further included:

[0029] S21. Then, start the first electric push rod and the second electric push rod in the first storage plate, drive the limiting plate to insert into the inside of the slot until the limiting plate can block the gap between the arc assembly and the storage hole, and then start the smelting operation, so that the arc assembly can continue to move downward under the action of the moving module until it contacts an object to generate an arc, and then retracts upward by a certain distance and remains stationary.

[0030] In step S3, the following steps are further included:

[0031] S31. When it is detected that the height of the metal accumulation far from the arc assembly in the arc furnace main body is much larger than the height of the melted metal around the arc assembly, drive the arc assembly to move upward through the moving module, then start the third electric push rod, pull out the blocking plug from the slot hole through the second connecting plate, and then the feeding device can be inserted into the inside of the arc furnace main body through the slot hole until the metal heights are consistent, and then drive the arc assembly to move downward again until the arc is successfully generated again.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. The present invention is provided with an arc furnace main body, a first jack, a plug rod, a first storage plate, a slot, a first electric push rod, a limiting plate and a second electric push rod. Before using the arc furnace main body, first fix the first storage plate on the furnace cover by the engagement of the plug rod and the first jack. Then, after pouring the raw materials into the arc furnace, drive the arc assembly to insert into the storage hole through the moving module. Then, start the first electric push rod and the second electric push rod in the first storage plate, push the opposite limiting plates to approach each other and move into the slot, so that the limiting plate can block the gap between the arc assembly and the storage hole, thereby reducing the probability of sparks splashing out during smelting to a certain extent.

[0034] 2. The present invention is provided with a slot hole, a blocking plug, a second connecting plate and a third electric push rod. During the process of smelting metal, start the third electric push rod on the outer surface of the arc furnace main body as needed. Then, the blocking plug can be driven to move under the action of the second connecting plate, so that the blocking plug is no longer engaged with the slot hole. Then, the feeding device can be inserted into the arc furnace main body from the slot hole as needed to push the metal with a relatively high accumulation, thereby improving the efficiency of metal smelting to a certain extent.

[0035] 3. In the process of smelting, the present invention is equipped with a second support plate, a hydraulic push rod, a connecting plate, a connecting rod, and an infrared scanner. According to the need, the hydraulic push rod on the second support plate is activated to push the connecting plate to move, so that the connecting rod can drive the third placement plate to rotate around the insertion block in the placement groove, and then the infrared scanner on the third placement plate can be driven to scan the arc furnace body at different angles, facilitating the smelting personnel to observe the smelting progress and improving the practicability and convenience of use of the intelligent arc furnace.

[0036] 4. Before using the arc furnace body, the present invention is equipped with a placement groove, a card slot, a third placement plate, an insertion block, and a second jack. First, align the insertion block on the third placement plate with the card slot and move the third placement plate so that it can move in the placement groove. When the insertion block moves into the upper second jack, release the third placement plate. Then, under the action of gravity, the lower insertion block of the third placement plate will also fall into the inside of the second jack, and then the third placement plate can be limited in the placement groove, thus improving the convenience of disassembly and assembly of the scanning module.

[0058] Further, the usage method of this intelligent electric arc furnace is as follows:

[0059] S1. Before using the intelligent electric arc furnace, first fix the first placing plate 14 on the furnace cover 11 by fitting the insertion rod 13 into the first jack 12. Then start the fourth electric push rod 26 on one set of the first support plates 25. Next, drive the baffle 28 connected thereto by the third connecting plate 27 to move upward, so that the baffle 28 no longer blocks the material inlet. Then send the metal to be smelted into the interior of the electric arc furnace main body 10 through the material inlet;

Then the infrared scanner 44 can be used to scan the arc furnace body 10 at different angles to observe the metal smelting situation in the arc furnace body 10. When it is detected that the height of the metal accumulation far from the arc assembly 8 in the arc furnace body 10 is much larger than the height of the metal melted around the arc assembly 8, start the third electric push rod 24, pull out the plug 22 from the slot hole 21 through the connecting plate two 23.
