Description

Technical Field

[0001] The present invention relates to the field of anode carbon block detection equipment, and in particular to a grading detection equipment and a detection method for carbon block mixtures based on a viscosity effect. Background Art

[0002] Anode carbon block is a very common product used in electrolytic cells, as shown in the attached figure of the specification. Figure 8 The figure shows the structure of the anode carbon block, the main raw materials of which are a mixture of calcined petroleum coke and asphalt, in which asphalt is used as a binder and calcined petroleum coke is used as the main material of the anode carbon block. After the mixture of asphalt and calcined petroleum coke is mixed, it is extruded to obtain the anode carbon block, and the anode carbon block is roasted to obtain the finished anode carbon block, so that it can be used as the anode end of the electrolytic cell.

[0003] After the anode carbon block is roasted, it is necessary to mix the calcined petroleum coke and the asphalt material, and then the mixture can be formed after the two are evenly mixed. However, between the steps of mixing the asphalt material and the calcined petroleum coke, the calcined petroleum coke needs to be crushed, that is, the whole piece of calcined petroleum coke is crushed and sieved to obtain anode carbon blocks of different sizes, and the calcined petroleum coke particles of different sizes are stored in separate warehouses. When using it, it is necessary to mix the calcined petroleum coke particles of different sizes with the asphalt material in different proportions to ensure the prepared anode carbon block (because the prepared anode carbon block needs to be used as the anode end of the electrolytic cell, but the conductive properties and resistivity of the calcined petroleum coke particles of different sizes are different, so when preparing the mixture before the anode carbon block is formed, it is necessary to mix the calcined petroleum coke particles of different sizes and proportions), and the following problems will arise with respect to the mixing method of the calcined petroleum coke particles and the asphalt material:

[0004] 1. The existing proportioning methods all use weighing to select calcined petroleum coke particles, and in order to ensure the viscosity of the asphalt material, the petroleum coke particles need to be mixed and transported in a high-temperature environment. Only after the anode carbon block is prepared can its internal combination be tested. This method requires waiting for the anode carbon block to be formed before testing, and the production and molding of the anode carbon block needs to be carried out in a high-temperature environment without stopping the machine, which will result in the test results not being known in the first time. Before it is found that the internal mixture ratio of the molded anode carbon block does not meet the production standard, a batch of anode carbon blocks that do not meet the molding standard will be prepared and molded, resulting in a waste of raw materials.

[0005] 2. Because different calcined petroleum coke particles need to be processed in different bins, when the size mixing ratio of the calcined petroleum coke particles inside the anode carbon block is detected to be incorrect, it is necessary to adjust the storage bins of multiple calcined petroleum coke particles, that is, to change the overall ratio of the calcined petroleum coke mixture. However, this method will put a burden on the mixing equipment, and once the mixing adjustment ratio of the calcined petroleum coke is still incorrect, the entire production line of the anode carbon block needs to be shut down, the mixing equipment needs to be cleaned, and the ratio needs to be re-adjusted, making the mixing adjustment process of the anode carbon block extremely complicated.

[0006] Based on the above problems, it is necessary to develop grading detection equipment and methods for carbon block mixtures based on the viscosity effect, which can make judgments based on the viscosity of different anode carbon block mixtures, so as to detect whether the amount of additives in the anode carbon block mixture at different stages meets the addition standards, so that the proportion of calcined petroleum coke particles of different sizes in the mixture meets the anode carbon block production requirements, thereby ensuring that the produced anode carbon blocks meet the preparation standards. Summary of the invention

[0007] The purpose of the present invention is to provide a grading detection device and a detection method for carbon block mixtures based on the viscosity effect, which can detect the viscosity state of the anode carbon block mixture to determine whether the proportion of the anode carbon block mixture at a certain stage meets the addition requirements, and perform viscosity judgment on the anode carbon block mixtures at different stages, so as to ensure that the prepared anode carbon blocks meet their production requirements.

[0008] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0009] The grading detection equipment for carbon block mixture based on viscosity effect includes a mixture conveying mechanism and a mixture detection mechanism.

[0010] Mixture conveying mechanism: connected with the anode carbon block mixture stirring device, including a conveying shell and a high-voltage power source, wherein the high-voltage power source is connected with the conveying shell, and when the high-voltage power source conveys fluid toward the conveying shell, the carbon block mixture in the anode carbon block mixture stirring device is sucked into the conveying shell;

The tip intake port is arranged inside the intake outer pipe, and a suction port is arranged on the intake outer pipe. The ejection pipe includes a docking end and an ejection end. When the intake pipe is connected to the ejection pipe, the tip intake port and the docking end are arranged non-contactingly.

[0013] The butt end of the ejection pipe is a smoothly inclined surface, and the tip suction port is located deep in the smooth inclined surface after being matched with the butt end; after passing through the smooth inclined surface of the butt end inside the ejection pipe, the inner wall of the ejection pipe gradually expands and extends to the ejection end position of the ejection pipe.

[0014] The ejection end of the ejection pipe is provided with an ejection port.

[0015] The high-pressure power source is a high-pressure air pump, which is connected to a flow control component and is communicated with the outer end of the tip suction port; the volume of gas delivered by the high-pressure air pump toward the tip suction port per unit time is controlled by the flow control component.

[0016] The pressure sensing assembly includes a pressure sensor, a plurality of the pressure sensors are closely arranged, and the arrangement direction of the plurality of pressure sensors is arranged toward the outlet position of the conveying shell; each of the pressure sensors is individually connected to the control system.

[0017] A film structure is provided on the outer side of the pressure sensor component and is covered thereon, and the film structure is a soft non-elastic deformable material.

[0018] The high-voltage power source is connected to a cleaning pipeline, and the connection between the high-voltage power source and the cleaning fluid is controlled by a switch member, so that the cleaning fluid is transported toward the transport housing through the high-voltage power source.

[0019] A weighing device is arranged in the stirring chamber connected to the conveying shell, and the dosage of the mixed material entering the conveying shell from the stirring chamber is weighed by the weighing device.

[0020] The detection method of the grading detection device of the carbon block mixture based on the viscosity effect comprises the following steps:

[0021] S1, the high-pressure power source is started, and the specified flow rate of fluid is delivered to the tip of the delivery shell and drawn into the interior of the port within a unit time, so that the initial kinetic energy of the fluid is ; E here is the total kinetic energy delivered by the high-pressure power source, m represents the mass of the fluid delivered per unit time, and v represents the velocity of the fluid; at the same time, the weighing device weighs the amount of the mixture entering the conveying shell from the mixing chamber to obtain the mass of the mixture entering the conveying shell;

[0022] S2, when the fluid is ejected from the tip suction port, the carbon block mixture enters the suction outer tube from the suction port due to fluid mechanics, and follows the fluid injection into the butt end of the ejection tube, and then enters the ejection tube;

[0023] S3, the fluid and the mixed material entering the ejection pipe adhere to the inner wall of the ejection pipe, thereby consuming the initial kinetic energy, and ejecting outward at the ejection end of the ejection pipe;

[0024] S4, the kinetic energy of the fluid and the mixture when they are ejected from the ejection end of the ejection pipe. ; Indicates the energy consumed by the fluid and mixture in the discharge pipe due to wear. It indicates the kinetic energy of the fluid and the mixture when it is ejected from the ejection end of the ejection pipe. It indicates the total mass of the fluid and the mixture when they are ejected from the ejection end of the ejection pipe. It represents the square of the jet velocity at the ejection end;

[0025] S5, the ejected fluid and mixture collide with the pressure sensing component. The specific value of the pressure on the pressure sensing component can be obtained, thereby measuring the final fluid and mixture speed information and bringing it into In the equation, we can get the loss due to viscosity. The energy size can be used to determine the viscosity of the carbon block mixture;

[0026] S6, after the detection is completed, the mixing ratio of different coke particles in the carbon block mixture is adjusted according to the obtained carbon block mixture viscosity information to complete the detection operation.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] When the device is set up, the viscosity detection operation of the carbon block mixture is realized by setting the mixture conveying mechanism and the mixture detection mechanism.

[0029] 1. When setting up the mixed material conveying mechanism, select the conveying shell and the high-pressure power source for setting, and convey the carbon block mixture to the conveying shell position through the high-pressure power source. And when setting up the conveying shell, select the ejector conveying assembly as the conveying shell for setting, so that the carbon block mixture with high viscosity can be easily sucked into the ejector conveying assembly, and at the same time, it can cooperate with the power provided by the high-pressure power source to spray toward the mixed material detection equipment, so as to ensure that the carbon block mixture with high viscosity will not adhere much in the conveying shell, and can easily achieve the detection function.

[0030] 2. The device also sets up a mixture detection device, and the mixture detection device selects a pressure sensing component for setting. When the mixture conveying mechanism conveys the carbon block mixture and applies a specified force to the carbon block mixture, the forces exerted on the pressure sensing component by carbon block mixtures of different viscosities are different. Therefore, the force information detected on the pressure sensing component is used to determine whether the viscosity of the carbon block mixture meets the mixing requirements.

[0041] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0042] Because the premise of preparing anode carbon blocks is to mix calcined petroleum coke particles of different sizes with asphalt in proportion, and then transport them to the molding mold for extrusion molding, and then roast the extruded anode carbon blocks to prepare anode carbon blocks that meet production standards. If the mixing ratio of the carbon block mixture before molding is inconsistent, or the mixture is unevenly mixed, it will directly affect the quality of the prepared anode carbon blocks; and the problems existing in the existing mixing equipment and mixing conditions are also mentioned above, as follows:

[0043] 1. The existing proportioning methods all use weighing to select calcined petroleum coke particles, and in order to ensure the viscosity of the asphalt material, the petroleum coke particles need to be mixed and transported in a high-temperature environment. Only after the anode carbon block is prepared can its internal combination be tested. This method requires waiting for the anode carbon block to be formed before testing, and the production and molding of the anode carbon block needs to be carried out in a high-temperature environment without stopping the machine, which will result in the test results not being known in the first time. Before it is found that the internal mixture ratio of the molded anode carbon block does not meet the production standard, a batch of anode carbon blocks that do not meet the molding standard will be prepared and molded, resulting in a waste of raw materials.

[0044] 2. Because different calcined petroleum coke particles need to be processed in different bins, when the size mixing ratio of the calcined petroleum coke particles inside the anode carbon block is detected to be incorrect, it is necessary to adjust the storage bins of multiple calcined petroleum coke particles, that is, to change the overall ratio of the calcined petroleum coke mixture. However, this method will put a burden on the mixing equipment, and once the mixing adjustment ratio of the calcined petroleum coke is still incorrect, the entire production line of the anode carbon block needs to be shut down, the mixing equipment needs to be cleaned, and the ratio needs to be re-adjusted, making the mixing adjustment process of the anode carbon block extremely complicated.

[0045] Therefore, effective testing of the carbon block mixture is required to ensure that the anode carbon blocks produced meet the production standards and meet the production requirements specified by the manufacturer. Because for the carbon block mixture, under a specified temperature environment, the viscosity of the carbon block mixture obtained by mixing different proportions of calcined petroleum coke particles is inconsistent; for example, if the proportion of small-sized coke particles is large and the proportion of large-sized coke particles is small, the mixed carbon block mixture will be more viscous than the standard carbon block mixture. Therefore, by testing the viscosity of the carbon block mixture, it is possible to determine whether the mixing ratio of the carbon block mixture is correct, and then adjust the proportion of coke particles in the carbon block mixture based on the viscosity information of the carbon block mixture detected.

[0046] Therefore, the following structure is set up:

[0047] The grading and detection equipment for carbon block mixtures based on the viscosity effect includes a mixture conveying mechanism 1 and a mixture detection mechanism 2. When setting up here, the mixture conveying mechanism 1 and the mixture detection mechanism 2 are set up to meet the needs of conveying and detecting the carbon block mixture. Because for the carbon block mixture, even if the mixture viscosity is low due to inconsistent mixing ratios, the viscosity of the carbon block mixture is still relatively large, so the mixture conveying mechanism 1 that needs to be set up can effectively convey the carbon block mixture and avoid the problem of large-area mixture adhesion; so it is necessary to ensure that the set mixture conveying mechanism 1 can convey the carbon block mixture to the mixture detection equipment in a state of less adhesion. The mixture detection device is used to detect the force of the carbon block mixture ejected from the conveying shell 3. For the carbon block mixture of standard viscosity, after being conveyed to the conveying shell 3 with a specified force and overcoming the force between the carbon block mixture and the inner wall of the conveying shell 3, the force acting on the mixture detection device after being ejected from the outer end of the conveying shell 3 is within a certain range. Therefore, when the viscosity of the carbon block mixture changes, the force between the carbon block mixture and the inner wall of the conveying shell 3 will change, thereby changing the force of the carbon block mixture acting on the mixture detection device to determine the specific change in the viscosity of the mixture. Therefore, the following specific structural settings are required for the above principle:

[0048] Mixture conveying mechanism 1: connected with the anode carbon block mixture stirring equipment, including a conveying shell 3 and a high-pressure power source, the high-pressure power source is connected to the conveying shell 3, when the high-pressure power source conveys fluid toward the conveying shell 3, the carbon block mixture in the anode carbon block mixture stirring equipment is sucked and brought into the conveying shell 3; the conveying shell 3 is an ejector conveying assembly 5, the ejector conveying assembly 5 includes an intake pipe 6 and an ejection pipe 7, the intake pipe 6 includes a tip intake port 8 and an intake outer pipe 9, the tip intake port 8 is arranged inside the intake outer pipe 9, and a suction port 10 is arranged on the intake outer pipe 9; the ejection pipe 7 includes a butt end 11 and an ejection end 12, when the intake pipe 6 is connected to the ejection pipe 7, the tip intake port 8 and the butt end 11 are arranged non-contactingly. During the setting, the high-pressure power source is connected to the conveying shell 3, and the fluid with a specified flow rate is conveyed toward the inside of the conveying shell 3 through the high-pressure power source; and when the high-pressure power source conveys the fluid at a high speed toward the conveying shell 3, the mixture in the stirring chamber connected to the conveying shell 3 is sucked into the conveying shell 3 because the greater the flow rate, the smaller the pressure, thereby realizing the material taking and conveying operation of the carbon block mixture. Here, when setting up, the ejector conveying assembly 5 is selected as the conveying shell 3 for setting up. In the setting connection, the high-pressure power source is connected to the feed port end position of the tip suction port 8, which is used to convey the fluid to the inside of the tip suction port 8; and the channel connected to the stirring chamber is connected to the suction port 10 of the suction outer tube 9; when the high-pressure power source conveys the high-speed fluid to the inside of the tip suction port 8, it is ejected from the inside position of the tip suction port 8. At this time, the fluid flow rate at the ejection position of the tip suction port 8 is large and the pressure is small, while the pressure at the suction inlet position of the suction outer tube 9 is large, so that the air at the suction port 10 position is sucked and flows toward the tip suction port 8, and then the carbon block mixture in the stirring chamber is sucked into the inside of the suction outer tube 9, and moves along with the fluid sucked by the tip suction port 8. The fluid ejected from the tip suction port 8 and the carbon block mixture sucked into the suction pipe 6 are sprayed to the butt end 11 of the ejection pipe 7 and ejected outward from the ejection end 12 of the ejection pipe 7 .

[0049] Mixture detection equipment: It is arranged in conjunction with the mixture conveying mechanism 1, and includes a pressure sensing component 4. The pressure sensing component 4 is arranged in conjunction with the outlet end position of the conveying shell 3. When the high-pressure power source conveys the carbon block mixture through the conveying shell 3, a force is generated on the pressure sensing component 4. The pressure sensing component 4 includes a pressure sensor, and a plurality of the pressure sensors are closely arranged, and the arrangement direction of the plurality of pressure sensors is arranged toward the outlet position of the conveying shell 3; each of the pressure sensors is individually connected to the control system. Here, by setting the pressure sensing component 4, it is ensured that the impact force of the fluid and the carbon block mixture is detected, and the plurality of pressure sensing components 4 are individually connected to the control system, and the pressure information is sensed by different pressure sensing components 4, and the pressure information is transmitted to the control system, so that the control system processes the pressure information, thereby judging the specific force conditions of the fluid and the carbon block mixture acting on the pressure sensing component 4, and analyzing the viscosity of the carbon block mixture.

[0050] The principle of the above structural setting is explained as follows:

[0051] When the high-pressure power source delivers a specified flow of fluid into the delivery housing 3 per unit time, the kinetic energy possessed by the fluid is fixed;

[0052] Right now, ; E here is the total kinetic energy delivered by the high-pressure power source, m represents the mass of the delivered fluid per unit time, and v represents the velocity of the fluid; it should be understood here that the above formula represents the total kinetic energy of the fluid entering the tip suction port 8, and the energy consumed by the friction inside the tip suction port 8 is negligible (because this part of the energy can be easily obtained by controlling the control variable method, so whether it is calculated or not does not affect the final measurement result);

[0053] Because for mixtures of different viscosities, the greater the viscosity, the greater the interaction force between the contacting object, and thus the dosage obtained during the suction process is also different. Therefore, when the fluid enters the inner part of the suction outer tube 9 from the suction port 10, due to the different viscosity of the mixture, it will be sucked into the inner part of the suction outer tube 9 in different dosages. Most importantly, according to the dosage of the mixture sucked into the inner part of the suction outer tube 9, it can be preliminarily judged whether the viscosity of the mixture meets the mixing requirements;

[0054] When the fluid carrying the mixture enters the inside of the ejection pipe 7, due to the viscosity of the mixture, an adhesion effect is generated between the fluid and the inner wall of the ejection pipe 7, thereby preventing the fluid carrying the mixture from being ejected outward from the ejection end 12 of the ejection pipe 7, thereby affecting the kinetic energy of the fluid and the mixture ejected at the ejection end 12 of the ejection pipe 7;

[0055] Right now, ;

[0056] For the above formula, Indicates the energy consumed by the fluid and the mixture in the ejection pipe 7 due to wear, represents the kinetic energy of the fluid and the mixed material when being ejected from the ejection end 12 of the ejection pipe 7, and It represents the total mass of the fluid and the mixed material when they are ejected from the ejection end 12 of the ejection pipe 7. It represents the square of the jet velocity at the ejection end 12;

[0057] According to the above formula, the greater the viscosity of the mixture, The larger the output kinetic energy The smaller it is, that is, the smaller the kinetic energy of the fluid and the mixture at the ejection end 12 of the ejection pipe 7 becomes, and the smaller the force acting on the pressure sensor component 4 becomes. It should be noted here that in the process of sucking the carbon block mixture during fluid transportation, the mass of the sucked mixture is uncertain due to viscosity, that is, the greater the viscosity, the less the mass of the sucked mixture, and the smaller the viscosity, the more the amount of the sucked mixture. Therefore, for the amount of the sucked mixture, a weighing device is provided in the stirring chamber connected to the conveying shell 3. The weighing device is used to weigh the amount of the mixture entering the conveying shell 3 from the stirring chamber, thereby solving the problem of one of the unknown variables and easily calculating the final output speed;

[0058] When the fluid and the mixture exert force on the pressure sensing component 4, according to the impulse calculation formula:

[0059] ;

[0060] The specific value of the pressure on the pressure sensor assembly 4 can be obtained, thereby measuring the final fluid and mixture speed information and bringing it into In the equation, we can get the loss due to viscosity. The energy size can be used to determine the viscosity of the carbon block mixture.

[0061] The above theory and structure settings are optimized as follows:

[0062] 1. As for the structural setting of the ejection pipe 7, because it is necessary to ensure that the ejection pipe 7 can smoothly spray the fluid and the mixture, and it is also necessary to ensure that the fluid and the mixture can effectively enter the inside of the ejection pipe 7, so when setting it here, the butt end 11 of the ejection pipe 7 is a smooth inclined surface, and the tip suction port 8 is located at the deep position of the smooth inclined surface after matching with the butt end 11; to ensure that the fluid and the mixture can effectively enter the inside of the ejection pipe 7, and avoid the problem of fluid and mixture transportation. After passing through the smooth inclined surface of the butt end 11 inside the ejection pipe 7, the inner wall of the ejection pipe 7 gradually expands and extends to the ejection end 12 position of the ejection pipe 7; it is also to ensure that the fluid and the mixture can be effectively ejected from the ejection end 12 position of the ejection pipe 7. In addition, the ejection end 12 position of the ejection pipe 7 is matched with an injection port 13, so that the fluid and the mixture can be accurately ejected outward from the ejection end 12 position of the ejection pipe 7.

[0063] 2. As for the high-pressure power source, the high-pressure power source is a high-pressure air pump, which is connected to a flow control component, and the high-pressure air pump is connected to the outer end position of the tip suction port 8; the flow control component is used to control the volume of gas delivered by the high-pressure air pump toward the tip suction port 8 per unit time, thereby achieving the purpose of accurately controlling the flow rate and flow velocity of the delivered fluid.

[0064] 3. A thin film structure is provided on the outer side of the pressure sensing component 4, and the thin film structure is a soft non-elastic deformable material. Since the carbon block mixture has a high viscosity, after the carbon block mixture hits the pressure sensing component 4, it will directly adhere to the pressure sensing component 4. Therefore, a thin film structure is provided on the outer side of the pressure sensing component 4. The thin film structure can be replaced after one detection test, so as to facilitate the subsequent viscosity detection of the carbon block mixture.

[0065] 4. A cleaning pipeline is connected to the high-voltage power source, and the connection between the high-voltage power source and the cleaning liquid is controlled by a switch, so that the cleaning liquid is transported toward the conveying shell 3 through the high-voltage power source. The purpose is to continue cleaning the inside of the conveying shell 3 to facilitate the subsequent detection operation of the carbon block mixture.

[0066] The detection method of the grading detection device of the carbon block mixture based on the viscosity effect comprises the following steps:

[0067] S1, the high-pressure power source is started, and the specified flow rate of fluid is delivered to the tip of the delivery shell 3 into the inside of the suction port 8 within a unit time, so that the initial kinetic energy of the fluid is ; Here, E is the total kinetic energy delivered by the high-pressure power source, m represents the mass of the fluid delivered per unit time, and v represents the velocity of the fluid; at the same time, the weighing device weighs the amount of the mixture entering the conveying shell 3 from the mixing chamber to obtain the mass of the mixture entering the conveying shell 3;

[0068] S2, when the fluid is ejected from the tip suction port 8, the carbon block mixture enters the suction outer tube 9 from the suction port 10 due to fluid mechanics, and follows the fluid injection into the butt end 11 of the ejection tube 7, and then enters the ejection tube 7;

[0069] S3, the fluid and the mixed material entering the ejection pipe 7 adhere to the inner wall of the ejection pipe 7, thereby consuming the initial kinetic energy, and are ejected outward at the ejection end 12 of the ejection pipe 7;

[0070] S4, when the fluid and the mixed material are ejected outward from the ejection end 12 of the ejection pipe 7, the kinetic energy ; Indicates the energy consumed by the fluid and the mixture in the ejection pipe 7 due to wear, represents the kinetic energy of the fluid and the mixed material when being ejected from the ejection end 12 of the ejection pipe 7, and It represents the total mass of the fluid and the mixed material when they are ejected from the ejection end 12 of the ejection pipe 7. It represents the square of the jet velocity at the ejection end 12;

[0071] S5, the ejected fluid and the mixed material collide with the pressure sensing component 4, according to The specific value of the pressure on the pressure sensor assembly 4 can be obtained, thereby measuring the final fluid and mixture speed information and bringing it into In the equation, we can get the loss due to viscosity. The energy size can be used to determine the viscosity of the carbon block mixture;

[0072] S6, after the detection is completed, the mixing ratio of different coke particles in the carbon block mixture is adjusted according to the obtained carbon block mixture viscosity information to complete the detection operation.

[0073] Therefore, the grading detection equipment and detection method for carbon block mixtures based on the viscosity effect can make judgments based on the viscosity of different anode carbon block mixtures, so as to detect whether the amount of additives in the anode carbon block mixtures at different stages meets the addition standards, so that the proportion of calcined petroleum coke particles of different sizes in the mixture meets the anode carbon block production requirements, thereby ensuring that the produced anode carbon blocks meet the preparation standards.
