Description

Technical Field

[0001] This application relates to the field of mold lubrication technology, and in particular to a lubrication system for a carbon block production mold. Background Technology

[0002] Carbon blocks are widely used in the aluminum electrolysis industry as cathodes in aluminum electrolysis cells due to their good electrical conductivity and corrosion resistance.

[0003] In related technologies, a paste produced by mixing and heating petroleum coke, graphite powder, and asphalt is poured into a charcoal block production mold. A vibration molding machine provides low / high amplitude vibration and creates a vacuum inside the mold to produce charcoal blocks. To prevent material from sticking to the mold cavity and causing cracks or pits on the charcoal block surface, manual oiling is applied inside the mold before the paste is poured in, before demolding.

[0004] However, manual brushing and spraying of oil is inefficient, and the oil is sprayed out in a mist under high pressure, which can be easily inhaled by workers, posing a safety hazard. Utility Model Content

[0041] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0042] Carbon blocks are widely used in the aluminum electrolysis industry as cathodes in aluminum electrolysis cells due to their good electrical conductivity and corrosion resistance.

[0043] In related technologies, a paste produced by mixing and heating petroleum coke, graphite powder, and asphalt is poured into a charcoal block production mold. A vibration molding machine provides low / high amplitude vibration and creates a vacuum inside the mold to produce charcoal blocks. To prevent material from sticking to the mold cavity and causing cracks or pits on the charcoal block surface, manual oiling is applied inside the mold before the paste is poured in, before demolding.

[0044] However, manual brushing and spraying of oil is inefficient, and the oil is sprayed out in a mist under high pressure, which can be easily inhaled by workers, posing a safety hazard.

[0045] In view of this, this application provides a lubrication system for a charcoal block production mold. The system comprises a moving component, a lubricant supply assembly, a power assembly, and at least one first nozzle. The first nozzle is connected to the lubricant supply assembly via the power assembly to form a lubricant flow path. The moving component moves the mold below the first nozzle, causing the first and second sides of the mold's extension direction to pass sequentially through the first nozzle. Thus, as the power assembly passes the first nozzle on the first and second sides respectively, the lubricant flow path is connected and disconnected accordingly. When the lubricant flow path is connected, the power assembly pushes the lubricant from the lubricant supply assembly to the first nozzle via the lubricant flow path. Therefore, before the lubricant flow path is disconnected, the first nozzle can spray lubricant onto the inner wall of the mold. Furthermore, the number and angle of the first nozzles can be adjusted as needed to ensure that the inner wall of the mold is comprehensively and evenly covered by lubricant, which can be oil. This configuration eliminates the need for manual entry into the mold to brush or spray oil, improving efficiency and reducing safety hazards.

[0046] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0047] See Figures 1 to 4The lubrication system for a charcoal block production mold provided in this application includes a lubrication device 100 and a moving part 200. The lubrication device 100 includes a lubricant supply assembly 110, a power assembly 120, and at least one first nozzle 130. The first nozzle 130 is connected to the lubricant supply assembly 110 through the power assembly 120 to form a lubricant flow path. The moving part 200 is used to drive the mold 400 to move below the first nozzle 130, so that the first side 410 and the second side 420 of the extension direction of the mold 400 pass through the first nozzle 130 in sequence. The power assembly 120 is configured to connect and disconnect the lubricant flow path when the first side 410 and the second side 420 pass through the first nozzle 130 respectively. When the lubricant flow path is connected, the power assembly 120 is also used to push the lubricant from the lubricant supply assembly 110 to the first nozzle 130 through the lubricant flow path. The first nozzle 130 is used to spray the lubricant onto the inner wall of the mold 400.

[0048] Specifically, the lubrication system for the charcoal block production mold can be installed in the charcoal block production workshop. The lubricant supply component 110 provides the mold 400 with the lubricant required for demolding. The first nozzle 130 sprays the lubricant from the lubricant supply component 110 in a mist form, allowing the lubricant to be sprayed more evenly on the inner wall of the mold 400, thus improving spraying accuracy. The inner wall of the mold 400 refers to its peripheral and bottom walls. The lubricant reduces friction between the mold 400 and the charcoal block, thereby reducing material sticking inside the mold 400 during demolding and reducing cracks or pits on the surface of the charcoal block.

[0049] To ensure that the lubricant is accurately sprayed onto the inner wall of the mold 400 through the nozzle, a power assembly 120 and a moving part 200 are provided. The first nozzle 130 is connected to the lubricant supply assembly 110 through the power assembly 120 to form a lubricant flow path. The power assembly 120 is used to connect and disconnect the lubricant flow path and push the lubricant from the lubricant supply assembly 110 to the nozzle, which can reduce the need for manual intervention. The moving part 200 is used to move the mold 400 under the first nozzle 130, so that the first side 410 and the second side 420 of the extension direction of the mold 400 pass through the first nozzle 130 in sequence. Thus, by pre-setting and adjusting the number and angle of the first nozzle 130, it is ensured that the lubricant sprayed from the first nozzle 130 can be sprayed onto the inner wall of the mold 400 as the mold 400 passes through the first nozzle 130.

[0050] The extension direction of mold 400 is the same as the direction in which the moving part 200 drives the mold 400 to move, as shown in the reference. Figure 3 and Figure 4 The X direction in the equation.

[0051] For example, the mold 400 can be a rectangular structure with a cavity. It is understood that, depending on the orientation of the mold 400 on the moving member 200, the extension direction of the mold 400 can be as follows: Figure 3 As shown in the length direction, the first side 410 and the second side 420 are the two sides of the length direction of the mold 400; the extension direction of the mold 400 can also be as follows. Figure 4 The width direction shown refers to the first side 410 and the second side 420, which are the two sides of the width direction of the mold 400. This application embodiment does not limit this aspect.

[0052] Furthermore, as the first side 410 passes the first nozzle 130, the first nozzle 130 will be in the same plane as the first side 410. By using the power component 120 to connect the lubricant circuit and push the lubricant to the first nozzle 130, as the moving component 200 continues to drive the mold 400 to move, the first nozzle 130 gradually moves closer to the second side 420 due to its deviation from the first side 410, so that the first nozzle 130 remains opposite to the inner cavity of the mold 400 during this process. Therefore, the lubricant sprayed from the first nozzle 130 can be sprayed onto the inner wall of the mold 400.

[0053] When the second side 420 passes the first nozzle 130, the first nozzle 130 will be in the same plane as the second side 420. That is to say, the first nozzle 130 is not opposite to the inner cavity of the mold 400 at this time. By using the power component 120 to disconnect the lubricant circuit, the lubricant is avoided from being sprayed outside the mold 400 and wasted.

[0054] In practice, the number and angle of the first nozzles 130 can be adaptively readjusted according to the model and size of the mold 400. This application embodiment will not elaborate on this further.

[0055] In summary, the charcoal block production mold lubrication system provided in this application embodiment utilizes a moving component 200 to move the mold 400 below the first nozzle 130, causing the first side 410 and the second side 420 of the mold 400 in the extension direction to sequentially pass through the first nozzle 130. Thus, when the power component 120 passes through the first nozzle 130 on the first side 410 and the second side 420 respectively, the lubricant flow path is connected and disconnected accordingly. Specifically, when the lubricant flow path is connected, the power component 120 pushes the lubricant from the lubricant supply component 110 through the lubricant flow path to the first nozzle 130. Therefore, before the second side 420 passes through the first nozzle 130, i.e., before the lubricant flow path is disconnected, the first nozzle 130 can spray lubricant onto the inner wall of the mold 400. Furthermore, the number and angle of the first nozzles 130 can be adjusted as needed to ensure that the inner wall of the mold 400 is comprehensively and evenly covered by lubricant, wherein the lubricant can be oil. This setup eliminates the need for manual entry into the mold 400 to brush or spray oil, improving efficiency and reducing safety hazards.

[0056] Continue reading Figure 1 In some embodiments, the power assembly 120 includes a main pipe 121 and at least one first control valve 123; a first nozzle 130 is connected to a lubricant supply assembly 110 via the main pipe 121 to form a lubricant flow path; the first control valve 123 is disposed on the main pipe 121 and is configured to open when the first side 410 passes the first nozzle 130 to connect the lubricant flow path, and to close when the second side 420 passes the first nozzle 130 to disconnect the lubricant flow path.

[0057] The main pipe 121 can guide the lubricant to flow smoothly. The lubricant flow path is controlled by the first control valve 123. When the first side 410 and the second side 420 pass through the first nozzle 130 respectively, the first control valve 123 can respond to the movement of the moving part 200 relatively quickly, and can complete the connection or disconnection of the lubricant flow path in a short time, which is beneficial to improving the stability of the lubrication process.

[0058] This application does not limit the specific type of control valve. For example, the control valve can be a manually operated valve, such as a shut-off valve, ball valve, or butterfly valve. Thus, by manually observing the movement of the moving part 200, when the first side 410 passes the first nozzle 130, the operator opens the manually operated valve to connect the lubricant flow path; when the second side 420 passes the first nozzle 130, the operator closes the manually operated valve to disconnect the lubricant flow path.

[0059] To improve user experience, please refer to Figure 1 and Figure 5In some examples, the lubrication system for the charcoal block production mold also includes a control device 300; the first control valve 123 is a first solenoid valve, and the control device 300 includes a control element 310 and a position detection element 320. The position detection element 320 and the first solenoid valve are both electrically connected to the control element 310; the position detection element 320 is used to detect whether the first side 410 passes through the first nozzle 130 and whether the second side 420 passes through the first nozzle 130.

[0060] The control element 310 is configured to open the first solenoid valve to connect the lubricant flow path when the position detection element 320 detects that the first side 410 passes the first nozzle 130, and to close the first solenoid valve to disconnect the lubricant flow path when the position detection element 320 detects that the second side 420 passes the first nozzle 130.

[0061] In this way, by utilizing the position information provided by the position detection component 320, the control component 310 can respond quickly and accurately control the opening and closing timing of the first solenoid valve to control the spraying time of the nozzle, ensuring that the lubricant can be sprayed and cover the inner wall of the mold 400 and avoid waste. The whole process does not require direct human intervention, reducing human error and lag.

[0062] The specific types of the control element 310 and the position detection element 320 are not limited in the embodiments of this application. For example, the control element 310 can be a programmable logic controller or an industrial computer; the position detection element 320 can be an encoder, a laser rangefinder or a photoelectric sensor.

[0063] To ensure that the power assembly 120 can push the lubricant from the lubricant supply assembly 110 to the first nozzle 130 via the lubricant flow path, the power assembly 120 further includes a pressure tank 124 containing compressed air; the main pipe 121 includes a first sub-pipe 1211 and a second sub-pipe 1212, the lubricant supply assembly 110 is connected to the inlet 101 of the pressure tank 124 via the first sub-pipe 1211, and the outlet 102 of the pressure tank 124 is connected to the first nozzle 130 via the second sub-pipe 1212 to form a lubricant flow path.

[0064] A first solenoid valve is provided on both the first sub-pipe 1211 and the second sub-pipe 1212; the pressure tank 124 is configured to, when connected to the lubricant flow path, push the lubricant to flow through the lubricant flow path to the first nozzle 130 by compressed air.

[0065] Thus, by using the compressed air in the pressure tank 124 to drive the flow of lubricant, it is ensured that the lubricant can reach the first nozzle 130 through the lubricant flow path at a stable pressure and speed, which helps to reduce the problem of uneven spraying caused by uneven lubricant supply. Furthermore, the pressure tank 124, the first battery valve and the main pipe 121 in the power assembly 120 are relatively simple mechanical structures, which helps to reduce maintenance difficulty and cost.

[0066] Specifically, by setting up a first sub-pipe 1211 and a second sub-pipe 1212, lubricant is guided from the lubricating oil supply assembly to the pressure tank 124, and then pushed by the pressure tank 124 to the first nozzle 130. The lubricant in the lubricant supply assembly 110 can flow to the pressure tank 124 under the guidance of gravity through the first sub-pipe 1211. The pressure tank 124, as the core component for lubricant delivery, uses internally stored compressed air to provide a stable pressure source for the lubricant, ensuring that the lubricant can flow smoothly to the first nozzle 130 under the guidance of the second sub-pipe 1212.

[0067] See Figure 1 For example, the pressure tank 124 includes a tank body 1241, a second control valve 1242, and a first air supply component 1243; an inlet 101 and an outlet 102 are provided on the tank body 1241, and the first air supply component 1243 is connected to the tank body 1241 through the second control valve 1242 to form a compressed air flow path. The first air supply component 1243 is used to provide compressed air to the tank body 1241 through the compressed air flow path.

[0068] In this way, the amount of compressed air entering the tank 1241 can be controlled by the second control valve 1242 to adjust the pressure inside the tank according to actual needs, ensuring that the lubricant is sprayed out at the required pressure and speed, which helps to improve the accuracy and uniformity of lubricant spraying.

[0069] In addition, by operating the second control valve 1242, the problem of excessive pressure caused by excessive compressed air entering the tank 1241 can be prevented, and the phenomenon of insufficient pressure caused by insufficient air supply can also be avoided, thus ensuring the stability of the lubrication system operation.

[0070] The specific type of the second control valve 1242 is not limited in this application embodiment. For example, the second control valve 1242 can be a manual regulating valve. The operator can manually rotate the handle or knob to adjust the valve opening time, that is, the connection time of the compressed air flow path, so that the first air source supply component 1243 can provide a suitable amount of compressed air to the tank 1241 through the compressed air flow path.

[0071] Alternatively, see 1 and Figure 5In a specific implementation, the second control valve 1242 is a second solenoid valve, and the control device 300 also includes a pressure detection element 330. Both the second solenoid valve and the pressure detection element 330 are electrically connected to the control element 310. The pressure detection element 330 is used to detect whether the pressure of the tank 1241 is lower than the first preset value. The control element 310 is also configured to control the second solenoid valve to open when the pressure detection element 330 detects that the pressure of the tank 1241 is lower than the first preset value, so as to connect the compressed air flow path and allow the compressed air from the first air source supply element 1243 to flow into the tank 1241 through the compressed air flow path.

[0072] In this way, the pressure inside the tank 1241 is detected by the pressure detection device 330, and the second solenoid valve is automatically opened by the control device 310 when the pressure is lower than the first preset value, so as to ensure that the tank 1241 always maintains the required working pressure, reduce the reliance on manual operation, reduce the possibility of human error, and improve the reliability and stability of the system.

[0073] It is understood that a value below the first preset value in this application embodiment indicates that the pressure inside the tank 1241 is insufficient and cannot drive the lubricant to spray out at a constant speed and pressure. The specific value of the first preset value can be set according to the actual situation, and this application embodiment does not limit it.

[0074] For example, the pressure sensing element 330 can be a piezoresistive pressure sensor, a capacitive pressure sensor, or a fiber optic pressure sensor.

[0075] See Figure 1 In some embodiments, the lubricant is waste oil, and the lubricant supply assembly 110 includes a filter element 111 and a storage unit 112 connected to the filter element 111; the storage unit 112 is connected to the first nozzle 130 via a power assembly 120, the filter element 111 is used to filter the waste oil, and the storage unit 112 is used to receive and store the filtered waste oil; or the lubricant is an emulsion and water, and the lubricant supply assembly 110 includes a stirrer 113 and a storage unit 112; the storage unit 112 is connected to the first nozzle 130 via a power assembly 120, a portion of the stirrer 113 is placed inside the storage unit 112, the storage unit 112 is used to store the emulsion and water, and the stirrer 113 is used to stir the emulsion and water evenly.

[0076] Among them, the use of filtered waste oil as a lubricant realizes the effective reuse of resources, reduces the cost of waste oil treatment and environmental pollution; the filter element 111 removes impurities from the waste oil, ensuring that the lubricant sprayed onto the inner wall of the mold 400 is pure, improving the lubrication effect and reducing pipe wear or blockage caused by impurities.

[0077] Emulsion and water are used as lubricants. The emulsion is a lubricant used for lubricating lathes and other equipment in the workshop. The emulsion may include mineral oil and anionic, cationic and nonionic surfactants. The emulsion and water are fully mixed by the stirring element 113 to ensure that the composition of the lubricant is consistent each time it is used, thereby improving the stability and consistency of the spraying effect.

[0078] In specific implementation, such as Figure 1 As shown, the storage unit 112 for lubricant that is waste oil or lubricant that is emulsion and water can be set in the same storage tank, which can reduce space occupation and make the lubrication system more compact as a whole.

[0079] Considering that mold 400, during use, applies pressure to the paste produced by heating and mixing petroleum coke, graphite fragments, and asphalt inside the cavity via a pressure plate, meaning that in addition to the inner cavity wall contacting the carbon block, the pressure plate will also contact the carbon block, please refer to [further details omitted]. Figure 1 In some examples, the lubrication device 100 further includes at least one second nozzle 140, and the power assembly 120 further includes a branch pipe 122; the moving part 200 has a first placement part 210 and a second placement part 220 arranged in sequence, the first placement part 210 is used to place the mold 400, the second nozzle 140 is disposed on the second placement part 220, and the second nozzle 140 is connected to the main pipe 121 through the branch pipe 122.

[0080] Branch pipe 122 is used to deliver a portion of the lubricant to the second nozzle 140 during the process of the power assembly 120 pushing the lubricant from the lubricant supply assembly 110 through the lubricant flow path to the first nozzle 130. The second nozzle 140 is used to spray a portion of the lubricant onto the pressure plate of the mold 400.

[0081] In this way, the friction between the mold plate and the paste can be reduced by using lubricant, preventing the paste from sticking to the plate, reducing cleaning workload and improving the yield of charcoal blocks.

[0082] Specifically, by setting up a branch pipe 122, the second nozzle 140 is connected to the main pipe 121 through the branch pipe 122. During the process of the power component 120 pushing the lubricant from the lubricant supply component 110 to the first nozzle 130 through the lubricant flow path, the lubricant will be split when it reaches the junction of the branch pipe 122 and the main pipe 121. Part of the lubricant can be guided to the second nozzle 140 through the branch pipe 122, and the rest of the lubricant can be guided to the first nozzle 130 through the main pipe 121, so that the first nozzle 130 and the second nozzle 140 spray lubricant on the inner wall of the mold 400 and the pressure plate simultaneously.

[0083] Among them, such as Figure 1 As shown, a first control valve 123 can also be installed on the branch pipe 122.

[0084] See Figure 1 and Figure 5 In a specific embodiment, the control device 300 further includes an alarm element 340 and at least one liquid level detection element 350, both of which are electrically connected to the control element 310. The liquid level detection element 350 is used to detect whether the liquid level of the lubricant in the tank 1241 is lower than a second preset value. The control element 310 is configured to control the alarm element 340 to sound an alarm when the liquid level detection element 350 detects that the liquid level of the lubricant in the tank 1241 is lower than the second preset value.

[0085] Thus, when the lubricant level in tank 1241 is lower than the second preset value by the level detection device 350, the alarm device 340 can be controlled by the control device 310 to issue an alarm in time, reminding the operator to check for any abnormalities and replenish the lubricant, which can reduce the situation where there is insufficient lubricant to supply the first nozzle 130 and the second nozzle 140.

[0086] For example, after prolonged use of the lubrication system, the pipeline of the power component 120 may be damaged or the connection between the power component 120 and the lubricant supply component 110 and the tank 1241 may become loose. This may cause the lubricant to leak during the process of flowing from the lubricant supply component 110 to the pressure tank 124 and not enter the tank 1241. The lubricant level in the tank 1241 can be detected by the level detection component 350, which can remind the operator to detect the abnormality in time.

[0087] The second preset value can be set according to actual needs, and this application embodiment does not limit it.

[0088] In a specific implementation, the number of level detection elements 350 can be set to two. One element is used to detect whether the level of lubricant in the tank 1241 is lower than a second preset value; the other element can be used to detect whether the level of lubricant in the storage container 112 is lower than a third preset value. The level detection element 350 can be an ultrasonic level sensor, a capacitive level sensor, or a pressure level sensor.

[0089] Considering that during the actual assembly of the lubrication system in the workshop, to avoid the installation positions of other equipment and devices in the workshop, the first nozzle 130 and the second nozzle 140 are relatively far from the pressure tank 124, resulting in the lubricant not being effectively flowed to the first nozzle 130 and the second nozzle 140 under the push of the compressed air provided by the first air source supply component 1243, see [reference needed]. Figure 6In some embodiments, the power assembly 120 further includes a second air supply component 150 and at least one third control valve 160; the first nozzle 130 and the second nozzle 140 are both connected to the second air supply component 150 through the third control valve 160, and the second air supply component 150 is used to provide compressed air to the first nozzle 130 and the second nozzle 140.

[0090] Thus, by providing additional compressed air pressure to the first nozzle 130 and the second nozzle 140 through the second air supply unit 150, the lubricant can still be effectively sprayed during long-distance transmission.

[0091] The third control valve 160 is used to control the flow rate of compressed air from the second air supply unit 150 to the first nozzle 130 and the second nozzle 140, so as to ensure that the pressure at the nozzle is maintained within a suitable range.

[0092] For example, the third control valve 160 can be a manual regulating valve, a solenoid valve, or a proportional valve, etc., and the embodiments of this application do not limit this.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
