Description

Technical Field

[0001] This invention generally relates to the field of kiln equipment technology, and specifically to a high-efficiency fully automatic vanadium-nitrogen alloy double-pusher kiln. Background Technology

[0002] Vanadium-nitrogen alloys, as a novel steel additive, can replace ferrovanadium in the production of microalloyed steel, significantly improving the overall properties of steel, including strength, toughness, ductility, and resistance to thermal fatigue. They can promote the upgrading of steel products at a lower cost, enhancing the safety of buildings and their components in practical applications, reducing steel consumption, and saving construction costs. It can be said that the application of vanadium-nitrogen alloys in the steel industry is becoming increasingly widespread.

[0003] Currently, most pusher-plate kilns for producing vanadium-nitrogen alloys employ single-return single-infeed or double-return double-infeed propulsion systems. However, during drying operations, the single-return single-infeed system's external circulation uses a single-plate structure, limiting the heating area of ​​the crucibles in the auxiliary kiln and resulting in longer drying times, thus affecting product output and increasing production costs. Conversely, the double-return double-infeed system uses a double-plate structure for external circulation, which increases the heating area of ​​the crucibles in the auxiliary kiln but also increases the number of crucibles used, further raising production costs. Therefore, existing propulsion systems suffer from an imbalance between production costs, equipment usage, and product quality. To address these issues, we propose a highly efficient, fully automated double-pusher-plate kiln for producing vanadium-nitrogen alloys. Summary of the Invention

[0028] The second control unit is also used to determine whether the moisture content ratio of the sampled material meets the standard. If it does, the current drying time is used as the final drying time of the material to be processed.

[0057] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0058] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] Example 1

[0060] Please refer to Figure 1 The schematic diagram shown below illustrates the structure of a high-efficiency fully automatic vanadium-nitrogen alloy double-pusher kiln provided by the present invention, comprising:

[0061] The main kiln 100 is provided with two sets of first conveying channels 104 extending along a first direction. The first conveying channels 104 are used to convey two sets of materials to be processed in parallel.

[0062] The structure of the first conveying channel 104 is, for example, a conveyor belt track; and the main control module 208 can be electrically connected to the drive mechanism of the two sets of first conveying channels 104 to control the two sets of first conveying channels 104 to operate simultaneously so as to convey two sets of materials to be processed in parallel.

[0063] Here, the first direction is, for example, Figure 1 The horizontal direction within. Based on the main kiln 100 in Figure 1 The position of the first conveying channel 104 indicates that it conveys the material to be processed from the left to the right side of the main kiln 100.

[0064] It should be noted that the length of the main kiln 100 can be set in the range of 10-50 meters depending on the production capacity. The effective cross-sectional width of the furnace of the main kiln 100 is, for example, 720mm-1000mm, and its height is, for example, 340mm-500mm. Furthermore, the main kiln 100 has, sequentially from the side near the kiln head propulsion mechanism 125 to the side near the transmission mechanism 102, a primary reduction and drainage section, a secondary reduction nitriding and K+ / Na+ drainage section, a high-temperature firing densification section, a cooling and nitrogen fixation section, and a cooling section; each process section can perform corresponding processing operations on the materials to be processed on the first conveying channel 104.

[0065] A secondary kiln 101 is provided with two sets of fourth conveying channels 107 extending along a first direction. The fourth conveying channels 107 are used to convey two sets of materials to be processed in parallel. The direction of the fourth conveying channels 107 is opposite to that of the first conveying channel 104.

[0066] The structure of the fourth conveying channel 107 is the same as that of the first conveying channel 104, and will not be described in detail here. The difference lies in: based on the auxiliary kiln 101 in... Figure 1 The position of the fourth conveying channel 107 indicates that it conveys the material to be processed from the right side to the left side of the auxiliary kiln 101.

[0067] It should be noted that the temperature inside the auxiliary kiln 101 is generally controlled below 300℃. The length of the auxiliary kiln 101 can be set in the range of 8-10 meters depending on the production volume. The effective cross-sectional width of the furnace chamber of the auxiliary kiln 101 is, for example, 360mm-540mm, and its height is, for example, 400mm-500mm. Furthermore, the auxiliary kiln 101 is also equipped with a forced air intake device to enhance the drying and drainage effect.

[0068] like Figure 1 As shown, the kiln also includes:

[0069] The transmission mechanism 102 includes a set of second conveying channels 105 extending along a second direction. The second conveying channels 105 are used to receive the materials to be processed output from the first conveying channel 104 and convey them sequentially along the second direction. The transmission mechanism 102 also includes a third conveying channel 106 extending along a first direction. The third conveying channel 106 is used to receive the materials to be processed output from the second conveying channels 105 and convey them sequentially along the first direction. The second direction is perpendicular to the first direction.

[0070] The structure of the second conveying channel 105 is the same as that of the first conveying channel 104, and will not be described in detail here. Here, the second direction is, for example,... Figure 1 The vertical direction within. From Figure 1 It can be seen that the second conveying channel 105 conveys the material to be processed from its upper end to its lower end.

[0071] The structure of the third conveying channel 106 is the same as that of the first conveying channel 104, and will not be described in detail here. Figure 1 It can be seen that the third conveying channel 106 conveys the material to be processed from its right side to its left side.

[0072] The transfer platform 103 is used to receive the materials to be processed output from the third conveying channel 106 and to allow each set of materials to be processed to simultaneously enter the two sets of fourth conveying channels 107.

[0073] In addition, such as Figure 1 As shown, the kiln also includes: a kiln head propulsion mechanism 125, which includes a fifth conveying channel extending along the second direction, and the fifth conveying channel and the second conveying channel 105 are in opposite directions. The fifth conveying channel is used to receive the material output from the fourth conveying channel 107 and convey the material sequentially along the second direction. The kiln head propulsion mechanism 125 also includes a sixth conveying channel extending along the second direction. A propulsion platform is provided between the fifth and sixth conveying channels. The sixth conveying channel and the fifth conveying channel have the same conveying direction. The propulsion platform is used to receive the material output from the fifth conveying channel and simultaneously send two groups of materials into the sixth conveying channel. The sixth conveying channel is used to receive the material output from the propulsion platform and simultaneously convey two groups of materials to two sets of first conveying channels 104.

[0074] Specifically, the materials to be processed, conveyed by the kiln head propulsion mechanism 125 to the two sets of first conveying channels 104, are processed simultaneously in the main kiln 100 and simultaneously conveyed to the second conveying channel 105. The second conveying channel 105 then conveys the materials to be processed one by one to the third conveying channel 106. The third conveying channel 106 then conveys the materials to be processed one by one to the transfer platform 103. Finally, the transfer platform 103, with each two sets of materials to be processed as a conveying unit, simultaneously conveys two sets of materials to be processed into the two sets of fourth conveying channels 107 each time, so that the materials to be processed can be dried in the auxiliary kiln 101, and finally the finished product is obtained.

[0075] This invention uses a second conveying channel 105 and a third conveying channel 106 to receive two sets of materials to be processed from two sets of first conveying channels 104, and conveys them sequentially. Then, a transfer platform 103 receives the materials to be processed output from the third conveying channel 106, and simultaneously conveys every two sets of materials to two sets of fourth conveying channels 107. By designing the material conveying structure between the main kiln 100 and the auxiliary kiln 101 as a single conveyor and double push-in form, the drying quality and efficiency of the materials in the auxiliary kiln are increased without changing the total amount of material transported in the kiln as a whole. This achieves a balance between production costs, equipment usage, and product quality, thus realizing the goal of cost reduction and efficiency improvement.

[0076] Furthermore, such as Figure 1 As shown, the forwarding platform 103 includes:

[0077] The propulsion mechanism includes: a first driving member 108 and a transfer member 109; the transfer member 109 is used to carry the material to be processed output from the third conveying channel 106; the first driving part of the first driving member 108 is connected to the transfer member 109 and is used to drive the transfer member 109 to move along the second direction so as to carry two sets of materials to be processed each time.

[0078] The first driving member 108 is, for example, a driving cylinder, with the end of its driving shaft serving as the first driving part; the transmission member 109 is, for example, a plate structure with a certain thickness. The driving cylinder can be connected to either end of the transmission member 109.

[0079] The propulsion mechanism also includes: a pusher 110, which is adjacent to and far away from the auxiliary kiln 101 and the transfer member 109; the pusher 110 has two pusher sections that correspond one-to-one with two sets of fourth conveying channels 107, and the two pusher sections are used to push the material to be processed to the two sets of fourth conveying channels 107 at the same time.

[0080] The pusher 110 can be composed of two drive cylinders; the ends of the drive shafts of the two drive cylinders are two pusher parts.

[0081] After the transfer member 109 receives a set of materials to be processed from the third conveying channel 106, the first driving member 108 drives the transfer member 109 to move a preset distance along the second direction. Then, the transfer member 109 receives another set of materials to be processed from the third conveying channel 106. At this time, the transfer member 109 has two sets of materials to be processed. The first driving member 108 drives the transfer member 109 to move along the second direction again, so that the two sets of materials to be processed move to the positions corresponding to the two pushing parts of the pushing member 110. The pushing part 110 is activated, so that the two pushing parts simultaneously push the two sets of materials to be processed into the two sets of fourth conveying channels 107.

[0082] Here, the preset distance refers to a distance that is less than the length of the transfer member 109 and greater than the width of the carrier member 114 of the material to be processed. The size of the preset distance can be set according to actual needs.

[0083] Furthermore, the surface of the transfer component 109 is provided with a mounting groove 111; the mounting groove 111 serves as the main load-bearing component of the correction mechanism.

[0084] like Figure 2 As shown, the forwarding platform 103 also includes:

[0085] The correction mechanism is disposed in the mounting groove 111. The correction mechanism includes a second driving member 112 and an adjusting plate 113. The cross-sectional area of ​​the adjusting plate 113 is smaller than the cross-sectional area of ​​the groove opening of the mounting groove 111. The second driving part of the second driving member 112 is connected to the adjusting plate 113 and is used to drive the adjusting plate 113 to move along the second direction, thereby driving the material to be processed on the surface of the transfer member 109 to move along the second direction.

[0086] It should be noted that the cross-sectional area of ​​the adjusting plate 113 is smaller than the cross-sectional area of ​​the groove of the mounting slot 111 in order to ensure that the adjusting plate 113 is movable in the second direction; and the cross-sectional area of ​​the adjusting plate 113 is also greater than the sum of the cross-sectional areas of the bearing members 114 of the two sets of materials to be processed, so as to ensure that the adjusting plate 113 can drive the two sets of materials to be processed to move simultaneously.

[0087] Among them, such as Figure 2 As shown, the specific structure of the second driving member 112 includes: a first slide rail 1120 formed at the bottom of the mounting groove 111 and extending along a second direction; a first driving cylinder 1121 provided at one end of the first slide rail 1120; a first slider 1122 connected to the drive shaft of the first driving cylinder 1121; and the first slider 1122 capable of moving along the second direction on the first slide rail 1120; a second driving cylinder 1123 provided on the first slider 1122; a second slider 1124 provided at the bottom of the adjusting plate 113; and the drive shaft of the second driving cylinder 1123 connected to the side of the second slider 1124 away from the adjusting plate 113. The drive shaft of the second driving cylinder 1123 can drive the adjusting plate 113 to move along the height direction of the mounting groove 111. Here, the second driving part is the end of the drive shaft of the second driving cylinder 1123.

[0088] In addition, to ensure stable movement of the adjusting plate 113 and the second slider 1124 during adjustment, an auxiliary moving structure was designed; such as Figure 2As shown, the auxiliary moving structure includes: two second slide rails 1125, which are disposed on two side walls of the mounting groove 111 along the length direction of the transfer member 109, and the two second slide rails 1125 can extend along the height direction of the mounting groove 111; the auxiliary moving structure also includes: a support rod 1126, whose two ends are slidably connected to the two second slide rails 1125 respectively; and a through hole is opened on the second slider 1124, through which the support rod 1126 passes, and the second slider 1124 can slide freely along the support rod 1126.

[0089] The first control unit 200 is communicatively connected to the first drive unit 108, the pusher 110, and the second drive unit 112. The first control unit 200 is used to control the start and stop of the pusher and the second drive unit 112 according to the position of the material to be processed moved by the first drive unit 108.

[0090] It should be noted that before the correction mechanism is operated, the upper surface of the adjusting plate 113 and the upper surface of the transfer component 109 are flush.

[0091] When the positions of the two sets of materials to be processed on the transfer member 109 deviate from the set positions, the first control unit 200 activates the second drive member 112. Specifically, the second drive cylinder 1123 first drives the second slider 1124 and the adjusting plate 113 to move along the height direction of the mounting groove 111. At this time, as the adjusting plate 113 moves, the support rod 1126 moves along the second slide rail 1125, so that the upper surface of the adjusting plate 113 is higher than the upper surface of the transfer member 109, thereby lifting the two sets of materials to be processed. Then, the first drive cylinder 1121 is activated, which drives the first slider 1122, the second slider 1124, and the adjusting plate 113 to move, thereby adjusting the positions of the two sets of materials to be processed. After the positions of the two sets of materials to be processed are adjusted, the first drive cylinder 1121 and the second drive cylinder 1123 are activated in sequence to restore the adjusting plate 113 to a position flush with the upper surface of the transfer member 109.

[0092] Here, "set position" refers to the position set according to the actual situation before the kiln performs processing tasks.

[0093] Specifically, such as Figure 6 As shown, the first control unit 200 includes:

[0094] Image acquisition module 201 is positioned above the transfer member 109, with its acquisition end facing the transfer member 109, and is used to acquire the first image in real time;

[0095] Here, the image acquisition module 201 is, for example, a camera.

[0096] The first processing module 202 is used to input the first image into the first model to obtain a position result; the position result is either a position alignment or a position offset.

[0097] Here, the first processing module 202 is, for example, a Siemens PLC programmable controller 6ES7315-2EH14-0AB0.

[0098] The first model is a simulation model constructed by the first processing module 202 based on the various components and structures of the actual kiln. The simulation model has two designated positions relative to the two pushing sections. These designated positions can be marked with dashed boxes in the simulation model.

[0099] The first image is input into the first model, and the positions of the two sets of materials to be processed in the first image relative to the two pushers are identified. The actual positions of the carriers 114 of the two sets of materials to be processed are marked and marked with wireframes that are different from the set positions. These are recorded as actual wireframes.

[0100] If the actual wireframe and the dashed wireframe completely overlap, the position result output by the first processing module 202 is "position aligned"; if the actual wireframe and the dashed wireframe do not overlap, the position result output by the first processing module 202 is "position offset".

[0101] The execution module 203 is used to generate a first control signal based on the position result and send it to the first drive unit 108 to control the start and stop of the push unit and the second drive unit 112.

[0102] Specifically, when the position result is a position offset, the execution module 203 starts the second driving component 112 and shuts down the push unit; when the position result is a position alignment, the execution module 203 shuts down the second driving component 110 and starts the push unit.

[0103] Here, the type of execution module 203 is, for example, a signal transmitter.

[0104] Furthermore, the kiln also includes multiple sets of support members 114, which are used to hold materials to be processed; wherein, one set of support members 114 holds one set of materials to be processed. Here, the material of the support member 114 is, for example, graphite.

[0105] like Figure 3 As shown, the carrier 114 includes:

[0106] The base plate 115 has a first side plate 116, a second side plate 117, a third side plate 118 and a fourth side plate 119 connected in a clockwise direction.

[0107] Multiple ventilation holes 120 are provided on the second side plate 117 and the fourth side plate 119;

[0108] The base plate 115, the first side plate 116, the second side plate 117, the third side plate 118, and the fourth side plate 119 together form a receiving space for holding materials to be processed.

[0109] The ventilation channels 120 are used to increase the contact area between the materials to be processed at various locations within the receiving space and the outside. Furthermore, the diameter of the ventilation channels 120 gradually decreases from the side closest to the receiving space to the side furthest away from the receiving space. For example, when the carrier 114 is located within the auxiliary kiln 101, the ventilation channels 120 can increase the contact area between the materials to be processed within the receiving space and the drying mechanism, ensuring that the materials to be processed at various locations within each set of carriers 114 are dried to a similar or consistent degree.

[0110] In other embodiments of the present invention, at least three bearing structures extending in a direction parallel to the bottom plate 115 are provided between the first side plate 116 and the third side plate 118 for bearing the material to be processed.

[0111] like Figure 4 As shown, the load-bearing structure includes:

[0112] The main support plate 122 has an elastic support plate 123 on the edge corresponding to the first side plate 116 and the third side plate 118; a support platform 124 is provided on the side of the elastic support plate 123 away from the main support plate 122.

[0113] When the load-bearing structure is placed in the accommodating space, the elastic support plate 123 abuts against the first side plate 116 and the second side plate 117, and the support platform 124 is flipped to be parallel to the first side plate 116 or the third side plate 118.

[0114] When the carrier 114 is inside the auxiliary kiln 101, the material to be processed in the accommodating space is placed in layers by the carrier structure, which increases the contact area between the material to be processed and the drying airflow of the auxiliary kiln 101 to a certain extent. This can not only improve the drying efficiency, but also make the drying effect of the material to be processed in each layer similar or consistent.

[0115] It should be noted that when installing the support structure, the support platform 124 should be placed between adjacent ventilation channels 120 to prevent the support structure from blocking the ventilation channels 120 and affecting the final drying consistency of the materials to be processed.

[0116] Furthermore, such as Figure 5 As shown, the main kiln 100 is sealed to the exhaust system 121. This sealed connection ensures that the nitrogen environment inside the furnace of the main kiln 100 is not affected by external airflow and is more stable. Furthermore, it keeps the nitrogen content in the final product within the range of 14-20%.

[0117] Furthermore, such as Figure 6 As shown, the first control unit 200 also includes:

[0118] Collision detection module 204 is installed on the auxiliary kiln 101. When the position result is that the position is aligned, the collision detection module 204 is used to detect whether the material to be processed and the kiln opening of the auxiliary kiln 101 will collide, and send the detection information to the first processing module 202.

[0119] The first processing module 202 is also used to analyze the detection information and obtain the detection results;

[0120] The execution module 203 is also used to generate a second control signal based on the detection result and send it to the second drive unit 112 to control the start and stop of the second drive unit 112.

[0121] Specifically, there are two collision detection modules 204, located on opposite sides of the kiln opening of the auxiliary kiln 101. The detection end of the collision detection module 204 faces the carrier 114 containing the material to be processed. When the position result is that the position is aligned, if the detection end of the collision detection module 204 detects the carrier 114, it generates detection information indicating that a collision has occurred and sends it to the first processing module 202. If the detection end of the collision detection module 204 does not detect the carrier 114, it generates detection information indicating that no collision has occurred and sends it to the first processing module 202.

[0122] The collision detection module 204 detects whether the carrier 114 and the kiln opening wall of the auxiliary kiln 101 of the two sets of materials to be processed will collide. If a collision occurs, the second drive unit 112 is activated to move the two sets of materials to be processed until the carrier 114 and the kiln opening of the auxiliary kiln 101 will not collide. If no collision occurs, the second drive unit 112 is controlled to be in the closed state.

[0123] Furthermore, the collision detection module 204 and the image acquisition module 201 respectively check whether the carrier 114 and the auxiliary kiln 101 will collide and whether the positions of the two sets of carriers 114 relative to the transfer component 109 are accurate, ensuring from two dimensions that the carrier 114 can be stably and smoothly pushed onto the two sets of fourth conveying channels 107.

[0124] Furthermore, such as Figure 6 As shown, the kiln also includes:

[0125] The second control unit 205 is communicatively connected to the auxiliary kiln 101. The second control unit 205 is used to call the drying parameter database and query the drying parameter database for the drying time and sampling moisture content ratio corresponding to the material whose code and quantity are completely consistent with the material to be processed. The drying parameter database includes at least: material code and corresponding material quantity, drying time and sampling moisture content ratio.

[0126] The drying parameter database is shown in Table 1.

[0127] Table 1 Drying Parameter Database

[0128]

[0129] The second control unit 205 is also used to determine whether the moisture content ratio of the sampled material meets the standard. If it does, the current drying time is used as the final drying time of the material to be processed. If it does not meet the standard, the drying time is adjusted and the adjusted drying time is used as the final drying time of the material to be processed.

[0130] The evaluation principle for whether the moisture content ratio of the sampled product meets the standard is that if the moisture content ratio is less than or equal to 0.1%, it is considered to meet the standard, and if the moisture content ratio is greater than 0.1%, it is considered to fail to meet the standard.

[0131] If the drying time is deemed substandard, the drying time will be increased by 10% each time until the moisture content of the sampled product corresponding to the adjusted drying time meets the standard. Furthermore, the relevant parameters will be added to the drying parameter database during each adjustment process for future use.

[0132] Furthermore, such as Figure 6 As shown, the kiln also includes: a sampling inspection unit 206;

[0133] The sampling inspection unit 206 is used to randomly select at least three sets of carrier components 114 as sampling inspection objects;

[0134] The sampling unit 206 is also used to construct a sampling coordinate system for each group of sampling objects, and to select the sampling area in the sampling coordinate system using a filter box;

[0135] A sampling coordinate system is constructed with any apex of the base plate 115 of the support member 114 as the origin, the X-axis being the extension of the length of the support member 114 passing through the origin, the Y-axis being the extension of the width of the support member 114 passing through the origin, and the Z-axis being the extension of the height of the support member 114 passing through the origin. Furthermore, the filtering box is a three-dimensional wireframe.

[0136] The sampling unit 206 is also used to select at least three coordinate positions in the sampling area, and calculate the first distance between each coordinate position and the origin of the sampling coordinate system, as well as the moisture content ratio of at least three materials to be processed at each coordinate position.

[0137] The sampling unit 206 is also used to construct a sampling curve based on the moisture content ratio and the first distance;

[0138] The sampling unit 206 is also used to analyze the sampling curve to obtain the drying effect; the drying effect is uniform drying or non-uniform drying.

[0139] If the moisture content ratio corresponding to all first distances in the sampling curve is less than or equal to 0.1%, the drying effect is uniform drying; if the moisture content ratio corresponding to all first distances in the sampling curve is greater than 0.1%, the drying effect is non-uniform drying.

[0140] If the drying effect is uneven, a receiving structure can be added to increase the contact area between the material to be processed and the drying airflow.

[0141] Furthermore, such as Figure 6 As shown, the kiln also includes: a crack detection unit 207;

[0142] The crack detection unit 207 is used to acquire material images when all materials are output from the auxiliary kiln 101;

[0143] Crack detection unit 207 is also used to identify and mark crack areas on material images;

[0144] The crack detection unit 207 is also used to obtain the location of the crack area within the auxiliary kiln 101;

[0145] The crack detection unit 207 is also used to call the drying parameter database according to the degree of crack in the crack area, and adjust the drying intensity corresponding to the material whose crack area in the auxiliary kiln 101 is completely consistent with the current material in terms of position, code, quantity, duration and moisture content ratio. The drying parameter database also includes the drying position and drying intensity corresponding to the material code, material quantity, drying duration and sampled moisture content ratio.

[0146] Specifically, the contact area between the drying airflow and the uppermost layer of material to be processed in each set of bearing components 114 is the largest. If the drying intensity is relatively high, the uppermost layer of material to be processed is very prone to cracks of varying degrees. Moreover, the number of drying airflow generating devices arranged on the auxiliary kiln 101 is also fixed. Areas where drying airflows overlap at different locations within the auxiliary kiln 101 will result in a greater drying intensity for the corresponding material to be processed, causing cracks in the material. Therefore, it is necessary to check whether the drying intensity in the drying parameter database is reasonable. The crack detection unit is used to obtain material images when all materials are output from the auxiliary kiln 101. Then, the crack areas on the material images are identified and marked. Correspondingly, the location of the crack areas within the auxiliary kiln 101 is found. Based on the degree of cracking in the crack areas, the drying intensity in the drying parameter database is adjusted.

[0147] The severity of cracking can be characterized by the proportion of crack area to the total area of ​​the material being processed. If the proportion is greater than or equal to 5%, the drying intensity in the drying parameter database needs to be adjusted. If the proportion is less than 5%, the drying intensity in the drying parameter database does not need to be adjusted.
