Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anode carbon block forming, in particular to an oil injection device and an anode carbon block forming system. Background Art
[0002] During the production process of anode carbon blocks, it is necessary to add a paste to an extrusion mold for extrusion to form anode carbon blocks. Since the paste itself is a raw material formed by mixing asphalt and calcined petroleum coke, after it is added to the mold, it has a certain viscosity. After the anode carbon block is extruded and formed, the adhesion between the anode carbon block and the inner wall of the mold cavity will be greater due to the influence of the extrusion force. In order to facilitate demolding of the anode carbon block after molding, when adding the paste to the mold, it is necessary to first apply or spray lubricating oil to the inner wall of the mold cavity to avoid large adhesion between the anode carbon block and the mold during molding.
[0003] In the prior art, in the process of mass production of anode carbon blocks, the anode carbon block extrusion molding die generally needs to be used in conjunction with a silo. The basic process of anode carbon block production is: the silo receives the material from the material conveying system and moves to between the upper and lower dies of the molding die, and then the material is lowered into the lower die. After that, the silo returns to receive the material again. During the process of the silo returning to receive the material again, the upper and lower dies are closed to realize the extrusion molding of the anode carbon block, and this process is repeated. It is conceivable that whether the lubricant is applied manually or sprayed with a tool, the anode carbon block production process usually needs to be suspended. The anode carbon block production process can only be resumed after the lubricant is applied or sprayed, resulting in low production efficiency. Utility Model Content

[0007] The oil spray device can be installed at the hopper of the anode carbon block forming system through a mounting frame and move with the movement of the hopper, so that the nozzle of the oil spray device can move with the hopper to between the upper mold and the lower mold to realize the oil spraying operation before unloading. For example, the oil spray device can move with the hopper while spraying oil to complete the oil spraying operation before the hopper moves into place and unloads. In addition, external lubricating oil can be fed into the nozzle through the pipeline assembly of the oil spray device to be sprayed out from the nozzle. Since the oil spray device includes a first nozzle and a second nozzle, and the nozzle of the first nozzle is set upward and the nozzle of the second nozzle is set downward, the cavity of the upper mold can be sprayed with oil through the first nozzle, and the cavity of the lower mold can be sprayed with oil through the second nozzle, thereby ensuring that the spraying operation can be completed quickly and effectively. In summary, in the process flow of batch production of anode carbon blocks, each link does not need to be paused or delayed, and the oil spraying operation can be carried out during the movement of the hopper without adding additional time for oil spraying, thereby improving the efficiency of batch production of anode carbon blocks and saving costs.

[0028] It should also be noted that the aforementioned X-axis, Y-axis, and Z-axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.
[0029] In the prior art, Figure 3-4As shown, in the mass production of anode carbon blocks, the anode carbon block extrusion molding die generally includes an upper die 61 (only the lower side is open), a lower die 62 (both the upper and lower sides are open), a bottom die 65, a hopper 63, and a bracket assembly 64. The upper die 61 and the lower die 62 are respectively used to move vertically along the bracket assembly 64. The hopper 63 is used to move along the bracket assembly 64, and the movement direction of the hopper 63 is perpendicular to the movement direction of the upper die 61. For example, the movement direction of the hopper 63 is the front-to-back direction (the X-axis direction in the figure). Among them, the downward-opening cavity of the upper die 61, the circumferential inner wall of the lower die 62, and the upward-facing cavity of the bottom die 65 together constitute the mold cavity.
[0030] In the prior art, when carrying out batch production of anode carbon blocks, the entire process generally includes the following steps: Step S1, moving the lower mold 62 to a position abutting the bottom mold 65, and moving the upper mold 61 upward to separate from the lower mold 62; Step S2, the hopper 63 moves backward to the material conveying system and receives the material (each time, it receives a piece of raw material required for forming the anode carbon block); Step S3, the hopper 63 moves forward until it moves between the upper mold 61 and the lower mold 62, and then the hopper 63 unloads the material to unload the raw material into the lower mold 62; Step S4, Step S4: The hopper 63 moves backward again to the material conveying system and receives the material. When the hopper 63 moves backward to the point where it does not interfere with the downward movement of the upper mold 61, the upper mold 61 will move downward to close the mold with the lower mold 62, thereby extruding to form the anode carbon block. The upper mold 61 is then reset upward, and the lower mold 62 also moves upward, so that the formed anode carbon block remains on the bottom mold 65. The anode carbon block on the bottom mold 65 is then pushed to the cooling system (the bottom mold does not affect the lateral movement of the anode carbon block). Step S5: Repeat the aforementioned steps S1-S4.
[0031] In the above step S4, after the anode carbon block is formed, due to its stickiness, in order to ensure that the upper mold 61 and the lower mold 62 can be smoothly separated from the anode carbon block and demolded, and also to ensure that the anode carbon block can be pushed away from the bottom mold 65, in the prior art, lubricating oil is generally applied manually to the inner wall of the mold cavity or sprayed with a tool. If the lubricating oil is applied manually, the application efficiency is slow, which will delay the original production process and reduce production efficiency. In addition, it may be necessary to pause a certain process to provide sufficient time for manual lubricating oil application. For example, after completing the above step S2, it is necessary to pause step S3 first. Step S3 can only be performed when the manual application is completed or nearly completed, resulting in low production efficiency and a waste of manpower. In addition, manual application also has certain safety hazards. Even if there is a method of spraying lubricating oil with a tool in the prior art, it is relatively limited in terms of improving production efficiency.
[0032] The utility model is to improve the production efficiency and labor cost of anode carbon blocks. Figure 1 、 Figure 3-4An oil injection device according to an embodiment of the present invention includes a mounting frame 1, a nozzle 2 and a pipeline assembly. The mounting frame 1 is used to be mounted on the silo 63 of the anode carbon block extrusion molding die and can move with the silo 63. The nozzle 2 and the pipeline assembly are respectively arranged on the mounting frame 1, and the pipeline assembly is connected to the inlet of the nozzle 2; wherein, the nozzle 2 includes at least a first nozzle 21 with a nozzle 204 facing upward and a second nozzle 22 with a nozzle 204 facing downward.
[0033] In this embodiment, the oil spraying device can be installed on the hopper 63 of the anode carbon block forming system through the mounting frame 1, and move with the movement of the hopper 63, so that the nozzle of the oil spraying device can move with the hopper 63 to between the upper mold and the lower mold to realize the oil spraying operation before unloading. For example, the oil spraying device can move with the hopper 63 while spraying oil to complete the oil spraying operation before the hopper moves into place and unloads. In addition, the external lubricating oil can be fed into the nozzle 2 through the pipeline assembly of the oil spraying device to be sprayed out from the nozzle 2. Since the oil spraying device includes a first nozzle 21 and a second nozzle 22, and the nozzles 204 of the two nozzles are arranged back to back, specifically, the nozzle 204 of the first nozzle 21 is arranged upward, and the nozzle 204 of the second nozzle 22 is arranged downward, the cavity of the upper mold 61 can be sprayed with oil through the first nozzle 21, and the cavity of the lower mold 62 can be sprayed with oil through the second nozzle 22, thereby ensuring that the spraying operation can be completed quickly and effectively. In summary, in the process flow of batch production of anode carbon blocks, each process link does not need to be paused or delayed, and the oil injection operation can be carried out during the movement of the hopper 63, without adding additional time for oil injection, thereby improving the efficiency of batch production of anode carbon blocks and saving costs.
[0034] The nozzle 204 of the first nozzle 21 is upwardly disposed, which may mean that the nozzle 204 is directed directly upward, or may be directed upward at a certain angle, that is, generally directed upward. Similarly, the nozzle 204 of the second nozzle 22 is downwardly disposed, which may mean that the nozzle 204 is directed directly downward, or may be directed downward at a certain angle, that is, generally directed downward.
[0035] Optionally, the mounting bracket 1 is used to be mounted at the front end of the silo 63 in the direction of feeding. Figure 3-4As shown, the oil spraying device is specifically arranged on the front side wall of the hopper 63 (the side wall at the positive end of the X-axis). Corresponding to the above-mentioned production process of the prior art, in step S3, the hopper 63 moves forward until the oil spraying device (specifically the nozzle 2) enters the cavity of the upper mold 61 and the rear end of the upper opening of the lower mold 62 (that is, the rear inner wall of the lower mold 62). At this time, the oil spraying device can be turned on to spray oil, so that the first nozzle 21 sprays oil to the cavity of the upper mold 61, and the second nozzle 22 sprays oil to the circumferential inner wall and bottom of the lower mold 62. The cavity of the mold 65 is sprayed with oil; when the oil spraying device (specifically the nozzle 2) continues to move forward with the hopper 63 until it reaches the front end of the cavity of the upper mold 61 and the upper opening of the lower mold 62 (i.e., the front side wall of the lower mold 62), the oil spraying can be stopped. At this time, the hopper 63 also moves into place and unloads the raw material into the lower mold 62; finally, the oil spraying device can spray oil as the hopper 63 moves, and stop spraying oil before the hopper 63 moves into place and the raw material is unloaded, which can save manpower and cost and improve production efficiency.
[0036] It should be noted that the oil injection device can be applied to any anode carbon block forming system having a movable hopper 63, and there is no restriction on whether the anode carbon block extrusion forming die in the anode carbon block forming system includes a bottom die 65 and other structures.
[0037] Optionally, the first nozzle 21 and the second nozzle 22 are spaced apart vertically, with the first nozzle 21 positioned near the upper end of the hopper 63 and the second nozzle 22 positioned near the lower end of the hopper 63. In this manner, the first nozzle 21, which sprays upward, can smoothly spray the lubricating oil onto the cavity of the upper mold 61, while the second nozzle 22, which sprays downward, can also smoothly spray the lubricating oil onto the circumferential inner wall of the lower mold 62 and the cavity of the bottom mold 65. This ensures that after the lubricating oil is sprayed from the nozzle 2, the lubricating oil can adhere to the inner wall of the mold cavity after a relatively short ejection stroke. Furthermore, the first nozzle 21 is relatively close to the upper mold 61 after it has been reset upward, ensuring that the lubricating oil can be sprayed onto the upper mold 61, while the second nozzle 22 is relatively close to the lower mold 62 after it has been reset downward, ensuring that the lubricating oil can be sprayed onto the lower mold 62 and the bottom mold 65.
[0038] See also Figure 1 Optionally, a plurality of first nozzles 21 are sequentially arranged along a direction perpendicular to the movement direction of the silo 63; and / or a plurality of second nozzles 22 are sequentially arranged along a direction perpendicular to the movement direction of the silo 63.
[0039] In this embodiment, for example, multiple first nozzles 21 are sequentially arranged along the left-right direction (lateral direction). Thus, the multiple first nozzles 21 can correspond to different lateral positions of the cavity of the upper mold 61. As these nozzles 2 move forward with the hopper 63, they can spray the cavity of the upper mold 61 comprehensively and evenly. Similarly, multiple second nozzles 22 are also sequentially arranged along the left-right direction (lateral direction). Thus, the multiple second nozzles 22 can correspond to different lateral positions of the lower mold 62 and the bottom mold 65. As these nozzles 2 move forward with the hopper 63, they can spray the lower mold 62 and the bottom mold 65 comprehensively and evenly.
[0040] Optionally, the inlet of the nozzle 2 includes an oil inlet 201 and an air inlet 202, and the pipeline assembly includes an oil supply pipeline 3 and an air supply pipeline 4, the oil supply pipeline 3 is connected to the oil inlet 201 of the nozzle 2, and the air supply pipeline 4 is connected to the air inlet 202 of the nozzle 2.
[0041] In this embodiment, external lubricating oil can be delivered to the oil inlet 201 of the nozzle 2 via the oil supply line 3, and compressed air can be delivered to the air inlet 202 of the nozzle 2 via the air supply line 4. Thus, with the air supply line 4 connected to the air inlet 202 of the nozzle 2 and the oil supply line 3 connected to the oil inlet 201 of the nozzle 2, when both oil and air are supplied simultaneously, the pressure and flow of the compressed air atomize the liquid oil, causing it to be sprayed out in the form of fine droplets, thereby forming atomized oil. The spraying of atomized oil widens the spraying range and the coating area, ensuring effective spraying of the mold cavity while also saving on lubricating oil usage.
[0042] Alternatively, see Figure 1 The oil supply pipeline 3 includes an oil supply main pipe 31 and two oil branch pipe assemblies 32, wherein one oil branch pipe assembly 32 is respectively connected to the oil supply main pipe 31 and the oil inlet 201 of the first nozzle 21, and the other oil branch pipe assembly 32 is respectively connected to the oil supply main pipe 31 and the oil inlet 201 of the second nozzle 22.
[0043] In this embodiment, the oil supply pipeline 3 specifically comprises an oil supply main pipe 31 and two oil branch pipe assemblies 32. The end of the oil supply pipeline 3 away from the oil branch pipe assemblies 32 can be connected to an external storage device. The two oil branch pipe assemblies 32 are respectively used to supply oil to the first nozzle 21 and the second nozzle 22. Specifically, one end of the two oil branch pipe assemblies 32 is respectively connected to the oil supply main pipe 31. For example, one end of the two oil branch pipe assemblies 32 and the oil supply main pipe 31 can be connected via a three-way valve, so that the oil supply main pipe 31 can simultaneously supply oil to both oil branch pipe assemblies 32. The other end of one set of oil branch pipe assemblies 32 is connected to the oil inlet 201 of the first nozzle 21, and the other end of the other set of oil branch pipe assemblies 32 is connected to the oil inlet 201 of the second nozzle 22.
[0044] Specifically, if Figure 1 As shown, the oil supply main pipe 31 is located between the first nozzle 21 and the second nozzle 22 , that is, the oil supply main pipe 31 is lower than the first nozzle 21 and higher than the second nozzle 22 , so as to improve the integration of the entire oil injection device.
[0045] See also Figure 1-2 Optionally, the oil branch pipe assembly 32 includes a primary oil branch pipe 321, a secondary circulation oil inlet branch pipe 322 and a secondary circulation oil return branch pipe 323, and the nozzle 2 further includes an oil return port 203;
[0046] One end of the secondary circulation oil inlet branch pipe 322 and one end of the secondary circulation oil return branch pipe 323 are both connected to the oil supply main pipe 31 through the primary oil branch pipe 321, the other end of the secondary circulation oil inlet branch pipe 322 is connected to the oil inlet port 201 of the nozzle 2, and the other end of the secondary circulation oil return branch pipe 323 is connected to the oil return port 203 of the nozzle 2, an oil inlet check valve 51 is provided at the secondary circulation oil inlet branch pipe 322, and an oil return check valve 52 is provided at the secondary circulation oil return branch pipe 323.
[0047] In this embodiment, each oil branch pipe assembly 32 includes a primary oil branch pipe 321, a secondary circulating oil inlet branch pipe 322, and a secondary circulating oil return branch pipe 323. Figure 2 As shown, taking the first nozzle 21 as an example, one end of the secondary circulation oil inlet branch pipe 322 is connected to the oil inlet 201 of the first nozzle 21, one end of the secondary circulation oil return branch pipe 323 is connected to the oil return port 203 of the first nozzle 21, one end of the primary oil branch pipe 321 is connected to the oil supply main pipe 31, and the other end of the primary oil branch pipe 321, the other end of the secondary circulation oil inlet branch pipe 322, and the other end of the secondary circulation oil return branch pipe 323 are connected. On this basis, an oil inlet check valve 51 is provided at the secondary circulation oil inlet branch pipe 322, and an oil return check valve 52 is provided at the secondary circulation oil return branch pipe 323. It can be understood that the oil inlet check valve 51 is configured to only allow oil to enter the oil inlet 201 of the first nozzle 21 from the secondary circulation oil inlet branch pipe 322, and the oil return check valve 52 is configured to only allow oil to flow back from the oil return port 203 of the first nozzle 21 to the secondary circulation oil return branch pipe 323.
[0048] Thus, when the oil supply pipe 31 supplies oil, the flow direction of the lubricating oil is as follows: Figure 2As shown by the direction of the solid arrow in the middle pipeline, the lubricating oil enters the oil inlet 201 of the first nozzle 21 from the first oil branch pipe 321 through the secondary circulation oil inlet branch pipe 322, and then enters the secondary circulation oil inlet branch pipe 322 again from the oil return port 203 of the first nozzle 21 through the secondary circulation return oil branch pipe 323, forming a circulation of the lubricating oil (the secondary circulation oil inlet branch pipe 322, the oil inlet 201 of the nozzle 2, the oil return port 203 and the secondary circulation return oil branch pipe 323 constitute a circulation pipeline); during the circulation of the lubricating oil, after the air supply pipeline 4 supplies compressed air to the air inlet 202 of the first nozzle 21, the compressed air flow sprays part of the lubricating oil from the nozzle 204 in the form of atomization. By circulating the lubricating oil at the nozzle 2, it is ensured that only the oil supply main pipe 31 needs to be connected to an external oil storage device during oil supply, so that the lubricating oil can be sprayed stably; and due to the design of the return oil one-way valve 52, the oil in the nozzle 2 can flow back to the secondary circulation return oil branch pipe 323 and the secondary circulation oil inlet branch pipe 322, preventing the oil from accumulating in the nozzle 2 and ensuring the normal operation of the nozzle 2.
[0049] Furthermore, for the first nozzle 21, since the nozzle 204 is positioned upward, that is, the nozzle 204 of the first nozzle 21 is higher than the oil inlet 201 and the oil return port 203, when the air and oil supply is stopped, the gas pressure and oil pressure in the first nozzle 21 disappear. Therefore, the oil that entered the first nozzle 21 from the secondary circulation oil inlet branch 322 at the last moment of oil pressure can flow back from the oil return port 203 to the secondary circulation oil return branch 323. In other words, the configuration of the circulation pipeline can prevent oil accumulation in the nozzle 2.
[0050] For the second nozzle 22, although the nozzle 204 of the second nozzle 22 is set downward, when the air supply and oil supply are stopped, in order to prevent the oil from leaking from the downward nozzle 204 of the second nozzle 22, a one-way valve can be provided at the nozzle 204, and the one-way valve is opened when the air supply is supplied and closed when the air supply is stopped to ensure that the oil will not leak from the nozzle 204 of the second nozzle 22.
[0051] Alternatively, see Figure 2 The air inlet 202 of the nozzle 2 is arranged opposite to the nozzle outlet 204 of the nozzle 2, the oil inlet 201 of the nozzle 2 is arranged opposite to the oil return outlet 203 of the nozzle 2, and the air inlet 202 and the nozzle outlet 204 of the nozzle 2 are respectively located on both sides of the line connecting the center of the oil inlet 201 to the center of the oil return outlet 203.
[0052] In this embodiment, not only are the oil inlet 201 and the oil return port 203 positioned opposite each other, but the air inlet 202 and the nozzle 204 are also positioned opposite each other. Furthermore, the air inlet 202 and nozzle 204 of the nozzle 2 are located on either side of a line connecting the center of the oil inlet 201 to the center of the oil return port 203. For example, for the first nozzle 21, the nozzle 204 is located above the line, while the air inlet 202 is located below it. The reverse is true for the first nozzle 21. Thus, as the oil flows from the oil inlet 201 to the oil return port 203, it is blown toward the nozzle 204 by the compressed gas, and is then sprayed out of the nozzle 204 in the form of an atomized mist.
[0053] Alternatively, see Figure 1 The air supply pipeline 4 includes an air supply main pipe 41 and two air branch pipe assemblies 42, wherein one end of one air branch pipe assembly 42 is respectively connected to the air supply main pipe 41 and the air inlet 202 of the first nozzle 21, and the other air branch pipe assembly 42 is respectively connected to the air supply main pipe 41 and the air inlet 202 of the second nozzle 22.
[0054] In this embodiment, one end of the two gas supply branch pipe assemblies 42 can be connected to the gas supply main pipe 41 through a three-way valve, that is, the gas supply main pipe 41 can simultaneously supply compressed gas to the two gas supply branch pipe assemblies 42, and the other end of one gas branch pipe assembly 42 is connected to the gas inlet 202 of the first nozzle 21 ( Figure 2 The direction of the hollow arrow is the direction in which the compressed air enters the first nozzle); the other end of the other air branch pipe assembly 42 is connected to the air inlet 202 of the second nozzle 22, thereby providing compressed gas to the first nozzle 21 and the second nozzle 22 at the same time.
[0055] Among them, Figure 1 As shown, the air supply pipeline 4 is located between the first nozzle 21 and the second nozzle 22, that is, the air supply pipeline 4 is lower than the first nozzle 21 and higher than the second nozzle 22, so as to improve the integration of the entire fuel injection device.
[0056] In this embodiment, when there are multiple second nozzles 22 and multiple first nozzles 21, each group of air branch pipe assemblies 42 includes a primary air branch pipe and multiple secondary air branch pipes, one end of the primary air branch pipe is connected to the gas supply main 41, one end of the multiple secondary air branch pipes is simultaneously connected to the primary air branch pipe, and the other ends of the multiple secondary air branch pipes are respectively connected to the air inlet 202 of the corresponding nozzle 2.
[0057] See also Figure 3-4Another embodiment of the present invention provides an anode carbon block forming system, including an anode carbon block extrusion forming mold, a silo 63 and the oil injection device as described above, the anode carbon block extrusion forming mold includes an upper mold 61, a lower mold 62 and a bracket assembly 64, the upper mold 61 is used to move along the bracket assembly 64 to close or separate the mold with the lower mold 62, the silo 63 is used to move along the bracket assembly 64 to enter or leave between the upper mold 61 and the lower mold 62, and the mounting frame 1 of the oil injection device is installed at the silo 63.
[0058] The difference between the anode carbon block extrusion forming die and the prior art is that the aforementioned oil spraying device is installed at the hopper 63, and the oil spraying device can move with the movement of the incoming hopper 63, and the external lubricating oil can be fed into the nozzle 2 through the pipeline assembly to be sprayed from the nozzle 2, so that the oil spraying device can move with the hopper 63 while spraying oil; in addition, the nozzle 204 of the first nozzle 21 is set upward, and the nozzle 204 of the second nozzle 22 is set downward, so that the first nozzle 21 can be used to spray oil into the cavity of the upper mold 61, and the second nozzle 22 can be used to spray oil into the cavity of the lower mold 62. In the process flow of batch production of anode carbon blocks, each link does not need to be paused or delayed, and the oil spraying operation can be carried out during the movement of the hopper 63 without adding additional time for oil spraying, thereby improving the efficiency of batch production of anode carbon blocks and saving costs. Optionally, the anode carbon block extrusion forming die can also include the aforementioned bottom mold 65.
[0059] Alternatively, see Figure 3-4 A first sensing device 66 and a second sensing device 67 are provided on the bracket assembly 64. When the oil spray device moves to a first position along the moving feeding direction of the silo 63, the first sensing device 66 is triggered; when the oil spray device moves to a second position along the moving feeding direction of the silo 63, the second sensing device 67 is triggered.
[0060] In this embodiment, when the oil spray device moves to the first position along with the moving feed bin 63, it indicates that the first nozzle 21 has just moved to a position where its oil spray range corresponds to one side (e.g., the rear side) of the cavity of the upper mold 61, and the second nozzle 22 has just moved to a position where its oil spray range corresponds to one side (e.g., the rear side) of the cavity of the lower mold 62. At this time, the first sensing device 66 corresponds to the oil spray device and senses that the oil spray device has moved to the first position. That is, the first sensing device 66 is triggered, and oil spraying can be started. When the oil spray device continues to move to the second position along with the moving feed bin 63, it indicates that the first nozzle 21 has moved to a position where its oil spray range corresponds to the other side (e.g., the front side) of the cavity of the upper mold 61, and the second nozzle 22 has just moved to a position where its oil spray range corresponds to the other side (e.g., the rear side) of the cavity of the lower mold 62. At this time, the second sensing device 67 corresponds to the oil spray device and senses that the oil spray device has moved to the second position. That is, the second sensing device 67 is triggered, and oil spraying can be terminated. It is understandable that when the oil injection device moves to the second position, the hopper 63 is exactly in the middle of the upper mold 61 and the lower mold 62, that is, the hopper 63 is in the unloading position and can be unloaded immediately after the oil injection is completed.
[0061] The first sensing device 66 and the second sensing device 67 may be infrared sensors, ultrasonic sensors, laser sensors, photoelectric sensors, etc.
[0062] Optionally, the anode carbon block forming system provided by the present invention may further include a material conveying system, and the material bin 63 of the anode carbon block extrusion forming die is used to move along the bracket assembly 64 to the material conveying system for receiving materials.
