[0034] The tank body 11 may be a cylinder, and a visual window 1111 is provided on the side of the tank body 11, through which the graphite electrode impregnation condition and the height of the impregnation liquid can be observed, so as to facilitate adding liquid at any time. Figure 1 As shown, the impregnation tank 1 also includes a support mechanism 19, which includes a base 191 and two or more support legs 192. The tank body 11 is mounted on the base 191, and the support legs 192 are mounted on the bottom of the base 191. The support legs 192 can improve the stability of the graphite electrode production impregnation treatment device 100 during operation. Among them, the rotating motor 141 is installed in the base 191, the lower end of the elastic telescopic component 142 extends into the base 191 and is connected to the output end of the rotating motor 141, and the upper end of the elastic telescopic component 142 extends into the tank body 11 and is connected to the bottom of the rotating plate 13.

[0035] The sealing cover 21 is sealed and connected to the tank body 11 through the tank body opening. Specifically, the tank body 11 is provided with a sealing ring on the inner side of the tank body opening, and the sealing cover 21 and the tank body 11 are sealed and connected through the sealing ring. Alternatively, an external thread is provided on the outside of the sealing cover 21, and an internal thread is provided at the tank body opening, and the sealing cover 21 and the tank body 11 are sealed and connected through the thread. Among them, the height of the liquid outlet of the liquid inlet pipe 121 along the first direction Z is higher than the height of the clamping plate 227 along the first direction Z.

When the clamping assembly 22 is actually used, the graphite electrode is first placed between the two clamping plates 227, and then the clamping motor 222 is started to rotate forward. The clamping motor 222 can rotate forward or reverse, and the output end of the clamping motor 222 drives the clamping screw 223 to rotate. The clamping screw 223 drives the clamping thread block 224 to slide upward along the first direction Z through the threaded connection relationship, thereby driving the corresponding clamping plates 227 to rotate around the clamping limit rod 226 through the clamping connecting rods 225 on both sides, until the clamping plates 227 on both sides clamp the graphite electrode and the clamping motor 222 can be turned off. When the graphite electrode is impregnated, the clamping motor 222 is started to reverse, and the output end of the clamping motor 222 drives the clamping screw 223 to rotate.

[0036] When the reciprocating component 143 is actually used, the fixed rod 1432 limits the inclined plate 1431 and repeatedly drives the elastic telescopic component 142 to perform reciprocating motion by pushing the bottom of the inclined plate 1431, thereby driving the rotating plate 13 and the graphite electrode on its top to perform reciprocating motion, that is, the graphite electrode can be driven to perform reciprocating motion during continuous rotation, and the clamping mounting block 221 can follow the graphite electrode to reciprocate inside the sealing cover 21. At the same time, the protrusion 211 can limit the clamping mounting block 221 from sliding out when it reciprocates along the first direction Z.

[0037] The technical solution of the present application clamps the graphite electrode on the sealing cover 21 through the clamping assembly 22 provided by the sealing mechanism 2, and then puts the sealing cover 21 clamping the graphite electrode into the tank body 11 to complete the impregnation, avoiding hand contamination caused by manual direct picking up of the graphite electrode, and during the impregnation process, the graphite electrode can be driven to rotate by the elastic telescopic assembly 142, and at the same time, the cooperation of the inclined plate 1431 and the fixed rod 1432 drives the graphite electrode to reciprocate and fluctuate along the first direction Z during the rotation process, which can achieve more uniform impregnation while increasing the contact area between the impregnation liquid and the graphite electrode, thereby improving the impregnation efficiency.

[0038] like Figure 3 As shown, the impregnation treatment device 100 for graphite electrode production also includes a sensing mechanism 3, which includes a first clamping sensor 31. The first clamping sensor 31 is installed at the bottom of the clamping mounting block 221 and is located between the two clamping plates 227. The first clamping sensor 31 is used to detect the state of the two clamping plates 227 clamping the graphite electrode.

[0039] The first clamping sensor 31 is an existing conventional sensor. In actual use, when the two clamping plates 227 clamp the graphite electrode, the graphite electrode is considered to be clamped when it contacts the first clamping sensor 31 or is set to reach the detection range of the first clamping sensor 31. Otherwise, an alarm can be issued and re-clamped. In some embodiments, the first clamping sensor 31 is also connected to the clamping motor 222 through a controller. When the first clamping sensor 31 detects that the graphite electrode is in place, the controller controls the clamping motor 222 to work, and the two clamping plates 227 clamp the graphite electrode. Preferably, the clamping plate 227 is arc-shaped, just fitting the shape of the graphite electrode, and an anti-skid pad can be set on the inner wall of the clamping plate 227 to enhance friction through the anti-skid pad to better clamp the graphite electrode. In addition, the clamping end of the clamping plate 227 extends a certain length so that the clamping plate 227 can clamp at least one-third of the graphite electrode.

[0040] In this way, the graphite electrode can be clamped better by providing the first clamping sensor 31 .

[0041] like Figure 2 As shown, the impregnation tank 1 also includes a graphite limit plate 15, which is mounted on the rotating plate 13, and the graphite limit plate 15 is used to limit and stabilize the bottom of the graphite electrode; the sensing mechanism 3 also includes a second position sensor 32, which is mounted on the rotating plate 13 and located in the graphite limit plate 15, and the second position sensor 32 is used to detect the state of the bottom of the graphite electrode placed in the graphite limit plate 15.

[0042] The graphite limiting plate 15 has a certain height along the first direction Z, and its inner diameter is larger than the graphite electrode. In actual use, the graphite electrode is placed in place only when the second position sensor 32 contacts or detects the graphite electrode within a certain range.

[0043] In this way, the second position sensor 32 is provided to detect whether the graphite electrode is placed in place, thereby ensuring the subsequent impregnation effect.

[0045] The side plate 111, the bottom plate 112 and the top plate 113 form a hollow space inside the tank body 11. The side plate 111 is provided with a visual window 1111, and the top plate 113 is provided with a tank body opening. A heating wire 16 is provided inside the side plate 111, and the heating wire 16 is spirally coiled. In some embodiments, a shell is provided outside the side plate 111, and a spiral heating wire 16 is provided between the side plate 111 and the shell.

[0046] A temperature sensor 33 may be provided at the upper end, the middle part and the lower end of the tank body 11, respectively. A stable average value of multiple temperature sensors 33 may be taken to make the temperature detection in the tank body 11 more accurate. Optionally, the temperature sensor 33 is connected to the heating wire 16 through a controller, and the controller controls the heating wire 16 to heat or stop heating according to the temperature detected by the temperature sensor 33, so that the temperature in the tank body 11 reaches a suitable temperature, so that the effect of impregnating the graphite electrode with the impregnation liquid in the tank body 11 is better.

[0047] In this way, by arranging the temperature sensor 33 in cooperation with the heating wire 16 , the impregnation liquid in the tank body 11 can better impregnate the graphite electrode.

The liquid outlet pump 129 cooperates with the liquid outlet valve 124. When the liquid outlet valve 124 is opened, the liquid outlet pump 129 works to allow the impregnation liquid in the tank body 11 to flow back to the external impregnation liquid tank 126.

[0050] In actual use, it is necessary to first add the impregnation liquid into the tank body 11. At this time, the control inlet pump 127 is started, and the outlet valve 124 is closed, so that the impregnation liquid in the external impregnation liquid tank 126 enters the tank body 11 through the liquid pipeline 125. At the same time, the filter 128 can filter the impurities in the impregnation liquid. When the impregnation liquid in the tank body 11 reaches the specified height, the control inlet pump 127 is stopped. After the impregnation liquid in the tank body 11 is used for a period of time or several graphite electrodes are impregnated, the outlet valve 124 is controlled to open, so that the impregnation liquid in the tank body 11 flows back to the external impregnation liquid tank 126, and the flow back can be accelerated by the outlet pump 129. Since the impregnation liquid that flows back will have residues of impregnated graphite electrodes, when the impregnation liquid in the external impregnation liquid tank 126 enters the tank body 11 again, the filter 128 can filter the impurities in the impregnation liquid to avoid the residues of the impregnation liquid in the tank body 11. The filter screen 128 can be detachably installed in the liquid inlet pipe 121 to facilitate subsequent cleaning.

[0051] By setting the liquid level sensor 34 to communicate with the liquid inlet pump 127, the liquid inlet pump 127 can be automatically started or shut down according to the height of the impregnation liquid in the tank body 11 detected by the liquid level sensor 34. In some embodiments, the liquid level sensor 34 is communicated with the liquid inlet pump 127 through a controller and is uniformly controlled by the controller. The controller can also be communicated with the liquid outlet valve 124 and the liquid outlet pump 129 for quick control.

[0052] By providing the liquid inlet mechanism 12, the impregnation liquid can be recycled and not wasted. In addition, the liquid level sensor 34 is connected to the liquid inlet pump 127 for communication, and the liquid inlet pump 127 can be automatically controlled to start or shut down, which is more intelligent.

[0053] like Figure 5 and Figure 6 As shown, the elastic telescopic component 142 includes a sliding column 1421, a rotating rod 1422, a mounting plate 1423 and an elastic member 1424. An inclined plate 1431 is fixedly installed outside the sliding column 1421, and a rotating plate 13 is fixedly installed on the top of the sliding column 1421. The interior of the sliding column 1421 is hollow, and limiting slide grooves 1426 extending along the first direction Z are provided on both sides of the inner wall of the sliding column 1421. The rotating rod 1422 is connected to the output end of the rotating motor 141, and sliders 1425 are provided on both sides of the rotating rod 1422. The sliders 1425 are slidably connected to the limiting slide grooves 1426. The limiting slide grooves 1426 are used to limit the rotation of the rotating rod 1422 relative to the sliding column 1421. A mounting plate 1423 is fixedly installed outside the rotating rod 1422, and an elastic member 1424 is installed between the mounting plate 1423 and the sliding column 1421.

[0054] The limiting slide groove 1426 can be C-shaped or U-shaped to limit the rotation of the rotating rod 1422 relative to the sliding column 1421, so that the sliding column 1421 can rotate together with the rotating rod 1422. An elastic member 1424 is installed between the mounting plate 1423 and the sliding column 1421, and has elasticity. Among them, the elastic member 1424 is elastic, can elastically shrink when subjected to pressure, and can restore its original shape when the pressure disappears. The elastic member 1424 can be made of metal elastic materials such as metal springs, or can be made of non-metal elastic materials such as rubber and silicone. Optionally, the elastic telescopic component 142 can also be an existing elastic telescopic rod.

[0055] When the reciprocating assembly 143 is actually used, the fixed rod 1432 limits the inclined plate 1431 and repeatedly drives the sliding column 1421 to perform reciprocating and undulating motion outside the rotating rod 1422 by pushing the bottom of the inclined plate 1431, thereby driving the rotating plate 13 and the graphite electrode on its top to perform reciprocating and undulating motion, that is, the graphite electrode can be driven to perform reciprocating and undulating motion during continuous rotation, and the clamping mounting block 221 can follow the graphite electrode to reciprocate inside the sealing cover 21. At the same time, the protrusion 211 can limit the clamping mounting block 221 from sliding out when it reciprocates along the first direction Z.

[0056] In this way, the telescopic function of the elastic telescopic assembly 142 is achieved through the cooperation of the sliding column 1421 , the rotating rod 1422 and the elastic member 1424 .

[0057] like Figure 2 , Figure 4 and Figure 5 As shown, the impregnation tank 1 also includes a stirring mechanism 17, which includes a main gear 171, a ring gear 172, two slave gears 173, two stirring connecting plates 174, two stirring rods 175 and more than two spoilers 176; the main gear 171 is fixedly mounted outside the rotating rod 1422 and is located below the mounting plate 1423, the ring gear 172 is sleeved outside the main gear 171, and the inner side of the ring gear 172 is meshed and connected with the main gear 171 through two slave gears 173, and a stirring connecting plate 174 is fixedly mounted on both sides of the outer side of the ring gear 172, and the stirring connecting plate 174 extends along the third direction X, and a stirring rod 175 is fixedly mounted on the stirring connecting plate 174, and spoilers 176 are evenly installed on the inner side of the stirring rod 175; wherein the first direction Z, the second direction Y and the third direction X are perpendicular to each other.

[0058] Optionally, in order to prevent the main gear 171, the ring gear 172, the two slave gears 173 and the rotating mechanism 14 from being affected by the dipping liquid in the dipping tank 1, a protective cover is provided between the rotating plate 13 and the bottom of the tank body 11, and the protective cover can rotate with the rotating mechanism 14. In some embodiments, since it is mainly the gears that are affected by the dipping liquid in the dipping tank 1, the protective cover can also be only provided outside the main gear 171, the ring gear 172, and the two slave gears 173 and rotate with them.

[0059] Among them, four spoilers 176 can be evenly arranged on the inner side of a stirring rod 175, and a temperature sensor 33 can be arranged between the spoilers 176 arranged adjacent to each other. In actual use, the rotating rod 1422 rotates under the drive of the rotating motor 141, and the rotating rod 1422 drives the main gear 171 fixedly installed on the outside to rotate, and the main gear 171 drives the two outer slave gears 173 to rotate through the meshing relationship, and the two slave gears 173 drive the gear ring 172 and the rotating rod 1422 to rotate in opposite directions through the meshing relationship, thereby driving the corresponding stirring rod 175 and the graphite electrode to rotate in opposite directions through the stirring connecting plates 174 fixed on both sides of the gear ring 172. As a result, the spoiler 176 rotates in opposite directions to the graphite electrode, so that the spoiler 176 pushes the impregnation liquid and the graphite electrode to flow in opposite directions, which can further increase the impregnation depth, thereby improving the impregnation efficiency.

[0060] like Figure 7 As shown, the immersion tank 1 also includes two cleaning brushes 18, one cleaning brush 18 is correspondingly installed on the outside of a stirring rod 175, the height of the cleaning brush 18 along the first direction Z is greater than or equal to the height of the stirring rod 175 along the first direction Z, the bristles of the cleaning brush 18 are in contact with the inner wall of the tank body 11, and the cleaning brush 18 is used to clean the inner wall of the tank body 11.

[0061] In this way, by providing the cleaning brush 18, the inner wall of the tank body 11 can be cleaned 360 degrees along with the rotation of the stirring rod 175, and the graphite electrode residue attached to the inner wall of the tank body 11 can be cleaned to prevent the graphite electrode residue from affecting the impregnation efficiency.

[0062] like Figures 1 to 3 As shown, the sealing mechanism 2 further includes a handle 23 , which is mounted on the top of the sealing cover 21 .

[0063] The graphite electrode can be inserted into the tank body 11 or taken out from the tank body 11 through the handle 23, thereby avoiding hand contamination caused by manual handling of the graphite electrode.

[0064] According to some embodiments of the present application, the present invention further provides an impregnation treatment method for graphite electrode production, including an impregnation treatment device 100 for graphite electrode production, and further including the following steps:

[0065] S101: injecting impregnation liquid into the interior of the tank body 11 through the liquid inlet pipe 121;

[0066] S102: Control the two clamping plates 227 to open relative to each other through the clamping motor 222, and then place the graphite electrode between the two clamping plates 227. After that, control the two clamping plates 227 to close relative to each other through the clamping motor 222 to clamp the graphite electrode.

[0067] S103: inserting the sealing cover 21 holding the graphite electrode into the tank body 11 through the tank body opening, placing the bottom of the tank body 11 on the rotating plate 13, and immersing the graphite electrode in the impregnation liquid;

[0068] S104: The rotating plate 13 is driven to rotate by the rotating motor 141, and the graphite electrode rotates accordingly. At the same time, the elastic telescopic component 142 rotates, the inclined plate 1431 rotates with the elastic telescopic component 142, and the fixed rod 1432 makes the rotating plate 13 reciprocate along the first direction Z, and the graphite electrode reciprocates accordingly.

[0069] In S103, it is important to explain that a main gear 171 is fixedly installed outside the elastic telescopic component 142, and the main gear 171, the slave gear 173 and the ring gear 172 cooperate to drive the stirring rod 175 and the spoiler 176 to rotate in the opposite direction to the graphite electrode, so that the spoiler 176 pushes the impregnation liquid and the graphite electrode to flow in the opposite direction, which can further increase the impregnation depth, thereby improving the impregnation efficiency.

[0070] After step S104, step S105 is also included: when the graphite electrode is completely immersed in the tank body 11, the clamping motor 222 is started to reverse, and the output end of the clamping motor 222 drives the clamping screw 223 to rotate, and the clamping screw 223 drives the clamping thread block 224 to slide downward along the first direction Z through the threaded connection relationship, thereby driving the corresponding clamping plate 227 to rotate around the clamping limit rod 226 through the clamping connecting rod 225 on both sides, until the clamping plates 227 on both sides release the graphite electrode, and then the clamping motor 222 can be turned off. After that, the graphite electrode can be taken out of the tank body 11 by the handle 23 to avoid manual contamination of the hand caused by manual direct taking of the graphite electrode.
