Description

Technical Field

[0001] The utility model relates to the technical field of power supply equipment, and more specifically, to a furnace tail trolley. Background Art

[0002] In the prior art, each graphitization furnace is still built by a separately constructed method. Conductive electrodes need to be provided at both the furnace head and the furnace tail of each graphitization furnace. Power supply is carried out by making the conductive electrodes at the furnace head and the furnace tail in a single furnace body conduct through a loop mode. The traditional mode of graphitization production is an intermittent single-furnace power transmission method. Its principle is that a rectifier transformer supplies power to a graphitization furnace. When a power transmission cycle ends, it returns to another graphitization furnace to conduct power again, and so on in a cycle. This cyclic production method has low output.

[0036] A first guide rail 111 is provided on one side of the furnace body 110 of the internal series graphitization furnace, that is, the first guide rail 111 is provided on the side close to the furnace head 111, and a second guide rail 112 is provided on the other side of the furnace body 110, that is, the second guide rail 112 is provided on the side close to the furnace tail 112, and the first guide rail 111 and the second guide rail 112 are arranged in parallel.

[0037] In this embodiment, a power supply device 200 is arranged on the first guide rail 111 on the side of the furnace head 111. The power supply device 200 is used to supply power to two independent internal series graphitization furnaces 100 at the same time. Among them, the two independent internal series graphitization furnaces 100 are respectively defined as a first graphitization furnace 101 and a second graphitization furnace 102. The first graphitization furnace 101 and the second graphitization furnace 102 are two adjacent internal series graphitization furnaces 100, or can also be two non-adjacent internal series graphitization furnaces 100, subject to actual application, which will not be elaborated here; the power supply device 200 itself does not involve the inventive points of the present utility model, and existing technical solutions can be adopted, such as the "graphitization dual-furnace power transmission system based on a large-current switch" disclosed in Chinese Patent CN201521043966.X, the "series-connected graphitization furnace mobile rectifier trolley" disclosed in Chinese Patent CN201120459310.1, etc.

[0038] An embodiment of the present utility model discloses a furnace tail trolley, which includes a moving vehicle body 300, a first pushing device 400 and a second pushing device 500 arranged on the moving vehicle body 300. A first pushing plate 410 is arranged at the first end of the first pushing device 400, and a second pushing plate 510 is arranged at the first end of the second pushing device 500. The first pushing plate 410 is used to connect the conductive electrode 120 of the furnace tail 112 of the first graphitization furnace 101, and the second pushing plate 510 is used to connect the conductive electrode 120 of the furnace tail 112 of the second graphitization furnace 102. The first pushing plate 410 and the second pushing plate 510 are connected through a connecting busbar 600. When the first pushing plate 410 is connected to the conductive electrode 120 of the furnace tail 112 of the first graphitization furnace 101 and the second pushing plate 510 is connected to the conductive electrode 120 of the furnace tail 112 of the second graphitization furnace 102, in cooperation with the power supply device 200 being connected to the conductive electrode 120 of the furnace head 111 of the first graphitization furnace 101 and the conductive electrode 120 of the furnace head 111 of the second graphitization furnace 102, power is supplied to the first graphitization furnace 101 and the second graphitization furnace 102 at the same time, so that the first graphitization furnace 101 and the second graphitization furnace 102 are connected in series. The length of the overall furnace core is greatly increased compared with the furnace core length of the traditional single graphitization furnace structure, the heat generation efficiency of the two graphitization furnace structures connected in series is improved, and thus the production efficiency of the graphitization furnace is effectively improved. In this embodiment, the moving vehicle body 300 itself is equipped with a driving device, and the driving force provided by the driving device drives the moving vehicle body 300 to be transported along the second guide rail 112. This is a known technology and will not be elaborated here.

[0039] In one embodiment, a first connection portion 411 is arranged on the first pushing plate 410, and a second connection portion 511 is arranged on the second pushing plate 510. Both ends of the connecting busbar 600 are respectively connected to the first connection portion 411 and the second connection portion 511. In this embodiment, the connecting busbar 600 is made of an aluminum bar or a copper bar or the like.

[0040] Furthermore, the connecting busbar 600 is composed of a plurality of soft connection rows 610 arranged vertically. One end of the soft connection row 610 is arranged on the first pushing plate 410, and the other end of the soft connection row 610 is arranged on the second pushing plate 510, thereby enhancing the stability of the connection between the first pushing plate 410 and the second pushing plate 510.

[0041] In this embodiment, the number of the connecting busbars 600 is two. One ends of the two connecting busbars 600 are respectively arranged on the front and back sides of the first pushing plate 410, and the other ends of the two connecting busbars 600 are respectively arranged on the front and back sides of the second pushing plate 510, further improving the stability of the connection between the first pushing plate 410 and the second pushing plate 510.

[0042] In one embodiment, the second end of the first pushing device 400 is used to connect to the external reaction wall 700, and the second end of the second pushing device 500 is used to connect to the external reaction wall 700. Thus, by utilizing the reaction force of the reaction wall 700, both the first end of the first pushing device 400 and the first end of the second pushing device 500 can apply forces to the corresponding conductive electrodes 120 better, ensuring the connection of the conductive electrodes 120 at the furnace tail 112 of the first graphitization furnace 101 and the conductive electrodes 120 at the furnace tail 112 of the second graphitization furnace 102. Then, in cooperation with the external power supply device 200 connecting to the conductive electrodes 120 at the furnace head 111 of the first graphitization furnace 101 and the conductive electrodes 120 at the furnace head 111 of the second graphitization furnace 102, the effect of simultaneously supplying power to the first graphitization furnace 101 and the second graphitization furnace 102 can be achieved, without the need to supply power to the first graphitization furnace 101 and the second graphitization furnace 102 respectively by an intermittent single-furnace power transmission method. Furthermore, the graphitization efficiency of the electrode columns to be graphitized in the first graphitization furnace 101 and the second graphitization furnace 102 is improved; in this embodiment, the reaction wall 700 is arranged on one side of the second guide rail 112.

[0043] In one embodiment, the first pushing device 400 further includes a first pushing mechanism 420, the first pushing mechanism 420 is connected to the first pushing plate 410, and the first pushing mechanism 420 is used to push the first pushing plate 410 to the conductive electrode 120 at the furnace tail 112 of the first graphitization furnace 101; the second pushing device 500 further includes a second pushing mechanism 520, the second pushing mechanism 520 is connected to the second pushing plate 510, and the second pushing mechanism 520 is used to push the second pushing plate 510 to the conductive electrode 120 at the furnace tail 112 of the second graphitization furnace 102.

[0044] Specifically, the first pushing mechanism 420 includes a first fixing frame 421 and at least one first pushing oil cylinder 422 fixedly arranged on the first fixing frame 421. The first fixing frame 421 is fixed on the moving vehicle body 300. A first push rod 4221 is arranged at the first end of the first pushing oil cylinder 422, and a first abutting rod 4222 is arranged at the second end of the first pushing oil cylinder 422. The first push rod 4221 is fixedly connected to the first pushing plate 410. The first pushing oil cylinder 422 drives the first push rod 4221 to reciprocate back and forth, and then drives the first pushing plate 410 to reciprocate with the movement of the first push rod 4221, so as to realize the contact or separation operation between the first pushing plate 410 and the conductive electrode 120 at the furnace tail 112 of the first graphitization furnace 101; Similarly, the first abutting rod 4222 is used to abut against the external reaction wall 700. The first pushing oil cylinder 422 drives the first abutting rod 4222 to reciprocate back and forth, and then drives the first abutting rod 4222 to move towards the reaction wall 700 to contact the reaction wall 700 or drives the first abutting rod 4222 to move away from the reaction wall 700 to separate from the reaction wall 700. When the first pushing oil cylinder 422 drives the first abutting rod 4222 to contact the reaction wall 700, the reaction wall 700 provides a reaction force to the first pushing mechanism 420, so that the first pushing mechanism 420 can more stably abut the first pushing plate 410 against the conductive electrode 120 at the furnace tail 112 of the first graphitization furnace 101.

[0045] The second pushing mechanism 520 includes a second fixing frame 521 and at least one second pushing oil cylinder 522 fixedly arranged on the second fixing frame 521. The second fixing frame 521 is fixed on the moving vehicle body 300. A second push rod 5221 is arranged at the first end of the second pushing oil cylinder 522, and a second abutting rod 5222 is arranged at the second end of the second pushing oil cylinder 522. The second push rod 5221 is fixedly connected with the second pushing plate 510. The second pushing oil cylinder 522 drives the second push rod 5221 to reciprocate back and forth, and then drives the second pushing plate 510 to reciprocate with the movement of the second push rod 5221, so as to realize the contact or separation operation between the second pushing plate 510 and the conductive electrode 120 at the furnace tail 112 of the second graphitization furnace 102; Similarly, the second abutting rod 5222 is used to abut against the external reaction wall 700. The second pushing oil cylinder 522 drives the second abutting rod 5222 to reciprocate back and forth, and then drives the second abutting rod 5222 to move towards the reaction wall 700 to contact the reaction wall 700 or drives the second abutting rod 5222 to move away from the reaction wall 700 to separate from the reaction wall 700. When the second pushing oil cylinder 522 drives the second abutting rod 5222 to contact the reaction wall 700, the reaction wall 700 provides a reaction force to the second pushing mechanism 520, so that the second pushing mechanism 520 can more stably abut the second pushing plate 510 against the conductive electrode 120 at the furnace tail 112 of the second graphitization furnace 102; When the first pushing oil cylinder 422 drives the first abutting rod 4222 to separate from the reaction wall 700 and the second pushing oil cylinder 522 drives the second abutting rod 5222 to separate from the reaction wall 700, it is convenient for the moving vehicle body 300 to drive the first pushing device 400 and the second pushing device 500 to move along the second guide rail 112 together, so as to facilitate the connection operation for the conductive electrodes 120 at the furnace tails 112 of the next group of adjacent two inner series graphitization furnaces 100; In this embodiment, both the first pushing oil cylinder 422 and the second pushing oil cylinder 522 are of hydraulic cylinder structure.

[0046] In one embodiment, abutting blocks 401 are arranged at one ends of the first abutting rod 4222 and the second abutting rod 5222. The abutting blocks 401 are threadedly connected with one ends of the first abutting rod 4222 and the second abutting rod 5222 respectively. The cross-sectional areas of the abutting blocks 401 are larger than the cross-sectional areas of the first abutting rod 4222 and the second abutting rod 5222. By arranging the abutting blocks 401, the contact area between the first pushing mechanism 420 or the second pushing mechanism 520 and the reaction wall 700 can be increased, and thus the service lives of the reaction wall 700, the first abutting rod 4222 and the second abutting rod 5222 can be prolonged.

[0047] Furthermore, the abutting block 401 is of cylindrical structure, and a rotating handle 402 is arranged to extend outward on the circumferential side of the abutting block 401. Manually rotating the rotating handle 402 can more conveniently fix the abutting block on the first abutting rod 4222 and the second abutting rod 5222.

[0048] In this embodiment, the number of the first pushing oil cylinders 422 and the second pushing oil cylinders 522 is designed to be 4. The 4 first push rods 4221 can be respectively connected to the four corners of the first pushing plate 410, and the 4 second push rods 5221 can be respectively connected to the four corners of the second pushing plate 510, so that the first pushing plate 410 and the second pushing plate 510 can contact the conductive electrode 120 more smoothly; and the 4 first abutting rods 4222 can be respectively in contact with the external reaction wall 700, and the 4 second abutting rods 5222 can be respectively in contact with the external reaction wall 700, so as to disperse the acting forces exerted by the first pushing device 400 and the second pushing device 500 on the reaction wall 700 and improve the service life of the reaction wall 700.

[0049] In one embodiment, cooling plates 800 are arranged between the first push rod 4221 and the first pushing plate 410, and between the second push rod 5221 and the second pushing plate 510. The first connecting portion 411 and the second connecting portion 511 both protrude out of the cooling plate 800, so as to facilitate the fixed connection of the first connecting portion 411 and the second connecting portion 511 to both ends of the connecting busbar 600 respectively, and improve the connection stability of the connecting busbar 600 to the first pushing plate 410 and the second pushing plate 510 respectively; the cooling plate 800 is hollow, and the cooling plate 800 is used to communicate with an external cooling tank. The cooling tank is used to supply cooling water to the cooling plate 800. The two cooling plates 800 are respectively used to cool the first pushing plate 410 and the second pushing plate 510. When the external power supply device 200 supplies power to the first graphitization furnace 101 and the second graphitization furnace 102, the first pushing plate 410 and the second pushing plate 510 will also generate heat. By arranging the cooling plate 800, the first pushing plate 410 and the second pushing plate 510 can be effectively cooled, and thus the service life of the first pushing plate 410 and the second pushing plate 510 is improved.

[0050] Specifically, a butt joint ring column 810 is arranged in the cooling plate 800. Through holes 811 are arranged at intervals on the butt joint ring column 810. The two cooling plates 800 are respectively connected to the first pushing plate 410 and the second pushing plate 510 through locking pieces 820. The locking pieces 820 pass through the through holes 811 and are respectively fixed in the first pushing plate 410 and the second pushing plate 510, so as to realize the fixed connection of the cooling plate 800 to the first pushing plate 410 and the second pushing plate 510; in this embodiment, the locking piece 820 is a screw structure.

[0051] Furthermore, one end of the docking ring column 810 is connected with a first docking plate 830 through a locking member 820. Second docking plates 403 are provided at one end of the first push rod 4221 and one end of the second push rod 5221. The first docking plate 830 is fixedly connected with the second docking plate 403, so as to achieve the effect that both the first push rod 4221 and the second push rod 5221 are fixedly connected with the cooling plate 800. Further, when the first push rod 4221 moves back and forth, the cooling plate 800 will also drive the first pushing plate 410 to move back and forth, so as to realize the operation of contacting or separating the first pushing plate 410 from the conductive electrode 120 at the furnace tail 112 of the first graphitization furnace 101. And when the second push rod 5221 moves back and forth, the cooling plate 800 will also drive the second pushing plate 510 to move back and forth, so as to realize the operation of contacting or separating the second pushing plate 510 from the conductive electrode 120 at the furnace tail 112 of the second graphitization furnace 102. In addition, by providing the first docking plate 830 at one end of the docking ring column 810 and cooperating with the second docking plates 403 provided at one end of the first push rod 4221 and one end of the second push rod 5221, the contact surface between the first push rod 4221 and the docking ring column 810 becomes larger, and the contact surface between the second push rod 5221 and the docking ring column 810 becomes larger, thereby preventing the situation that the local pressure of the cooling plate 800 becomes too large and causes damage when the first pushing plate 410 contacts the conductive electrode 120 at the furnace tail 112 of the first graphitization furnace 101 and when the second pushing plate 510 contacts the conductive electrode 120 at the furnace tail 112 of the second graphitization furnace 102.

[0052] Furthermore, a first insulating plate 840 is provided between the first docking plate 830 and the second docking plate 403. The first insulating plate 840 separates the first docking plate 830 from the second docking plate 403, thereby avoiding the situation that the electricity on the first pushing plate 410 is transmitted to the first push rod 4221 through the cooling plate 800 and the electricity on the second pushing plate 510 is transmitted to the second push rod 5221 through the cooling plate 800, and further improving the service life of the first push cylinder 422 and the second push cylinder 522.

[0053] In one embodiment, sliding mechanisms 900 are provided below the first pushing plate 410 and below the second pushing plate 510. The sliding mechanisms 900 are placed on the moving vehicle body 300. On the one hand, the sliding mechanisms 900 are used to support the first pushing plate 410 and the second pushing plate 510, and on the other hand, they are used to operate back and forth on the moving vehicle body 300. Specifically, the sliding mechanism 900 includes a second insulating plate 910 provided below the cooling plate 800 and / or on the moving vehicle body 300 and a pulley 920 connected to the second insulating plate 910. The second insulating plate 910 is used to insulate the first pushing plate 410 and the second pushing plate 510 from the moving vehicle body 300, preventing the electricity on the first pushing plate 410 and the second pushing plate 510 from being transmitted to the moving vehicle body 300 and causing safety accidents. For example, the moving vehicle body 300 transmits electricity to the second guide rail 112, resulting in the second guide rail 112 being charged. In this embodiment, taking the second insulating plate 910 being provided below the cooling plate 800 as an example, the second insulating plate 910 is arranged between the cooling plate 800 and the pulley 920. The pulley 920 is placed on the moving vehicle body 300. On the one hand, the sliding is used to support the first pushing plate 410 and the second pushing plate 510 connected to the cooling plate 800, and on the other hand, when the first push rod 4221 and the second push rod 5221 move back and forth, the pulley 920 will also move back and forth on the moving vehicle body 300 along with the first push rod 4221 and the second push rod 5221.

[0054] When the furnace tail trolley of the present utility model works specifically, the moving vehicle body 300 drives the first pushing device 400 and the second pushing device 500 to move to one side of two in-series graphitization furnaces 100 to be electrified. The first pushing device 400 and the second pushing device 500 are started. The first pushing oil cylinder 422 drives the first push rod 4221 and the first abutting rod 4222 to extend, and the second pushing oil cylinder 522 drives the second push rod 5221 and the second abutting rod 5222 to extend, so that the first pushing plate 410 contacts the conductive electrode 120 of the furnace tail 112 of the first graphitization furnace 101, the second pushing plate 510 contacts the conductive electrode 120 of the furnace tail 112 of the second graphitization furnace 102, and the abutting block 401 contacts the reaction wall 700. Cooperating with the connection of the first pushing plate 410 and the second pushing plate 510 through the connecting bus bar 600, the conductive electrodes 120 of the furnace tails 112 of the two in-series graphitization furnaces 100 are thus connected, so that the electrode columns to be graphitized in the two in-series graphitization furnaces 100 are connected together, causing the first graphitization furnace 101 and the second graphitization furnace 102 to be connected in series. The length of the overall furnace core is almost doubled, which is greatly increased compared to the furnace core length of the traditional single graphitization furnace structure, resulting in a significant increase in the ohmic resistance of the overall furnace core of the two connected graphitization furnaces and improving the heat generation efficiency of the structure of the two graphitization furnaces connected in series. That is to say, this power transmission method is equivalent to the furnace tail trolley being able to supply power to multiple graphitization furnaces at one time, effectively improving the production efficiency of the graphitization furnace.

[0055] In summary, for a furnace tail trolley of the present utility model, by arranging a first pushing device 400 and a second pushing device 500 on a moving vehicle body 300, and using a first pushing plate 410 of the first pushing device 400 and a second pushing plate 510 of the second pushing device 500 to respectively abut against conductive electrodes 120 at the furnace tails 112 of two inner series-type graphitization furnaces 100, the electrode columns to be graphitized in the two inner series-type graphitization furnaces 100 are connected together, so that the first graphitization furnace 101 and the second graphitization furnace 102 are connected in series. The length of the overall furnace core is greatly increased compared with the furnace core length of the traditional single graphitization furnace structure, the heat generation efficiency of the two graphitization furnaces connected in series is improved, and thus the production efficiency of the graphitization furnace is effectively improved.
