Description

Technical Field

[0001] The utility model belongs to the field of roller hearth kilns, and particularly relates to a steering device for a roller hearth kiln and the roller hearth kiln. Background Art

[0002] A roller hearth kiln is an industrial kiln furnace, and its main feature is the use of roller rods as transfer tools for continuous firing. The roller hearth kiln has a unique structural design and can effectively achieve the continuous transportation and firing of products under high-temperature conditions. It is widely used in industries such as ceramics, glass, and building materials, especially suitable for products that require strict control of firing temperature and time in mass production.

[0003] When products need to be fired in a protective atmosphere, replacement chambers are usually installed at both ends of the roller hearth kiln to discharge impurity gases. The main function of these replacement chambers is to discharge the impurity gases in the kiln to ensure a stable and pure atmosphere in the kiln, thereby avoiding the influence of impurities on the product quality. The replacement chambers achieve a dynamic balance of the atmosphere in the kiln by continuously introducing and discharging gases. This can not only effectively prevent oxidation reactions but also prevent the corrosion and pollution of products caused by some harmful gases.

[0004] Generally, the saggers containing powder materials enter the replacement chamber in rows and then still enter the furnace body for heating in rows, resulting in a relatively wide hatch of the replacement chamber, which is not conducive to the airtightness of the replacement chamber; if the saggers enter the replacement chamber in a single column, the hatch can be significantly narrowed, but the saggers need to enter the heating furnace body in a row in the next process, so it is necessary to realize the turning of the saggers between the replacement chamber and the heating furnace body. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a steering device for a roller hearth kiln and the roller hearth kiln, so that the material realizes the transportation turning in the turning chamber, and the row direction of the material relative to the moving direction changes, thereby realizing the turning of the material, and the material fed in a column can be sent out in a row.

[0014] Furthermore, a number of ceramic wheels coaxial with the power-free roller rods are arranged on each power-free roller rod.

[0016] Furthermore, the rotation driving mechanism includes a driving main shaft and a driving driven shaft. The driving main shaft is perpendicular to the driving driven shaft, and the driving driven shaft is driven by a helical gear, bevel gear or synchronous belt with the driving main shaft; the driving driven shaft is docked with the rotating roller rods.

[0017] Furthermore, the conveying roller assembly further includes a support seat arranged on one side of the steering bin. The support seat includes a mounting frame and a number of rotating wheels rotatably arranged on the mounting frame;

[0018] At least one end of each power-free roller rod is supported by two rotating wheels;

[0019] At least one end of each rotating roller rod is supported by two rotating wheels.

[0020] Furthermore, the pushing / pulling mechanism includes a horizontal linear driving member and a pushing / pulling rod. One end of the pushing / pulling rod is connected to the output end of the horizontal linear driving member, one end penetrates into the steering bin, and a pushing / pulling plate is vertically arranged.

[0025] The beneficial effects of the present utility model:

[0026] The steering device of the present utility model pushes or pulls the material from the side by setting a push / pull mechanism perpendicular to the conveying direction, and the material realizes the conveying steering in the steering chamber, and the row direction of the material relative to the moving direction changes, so as to realize the steering of the material.

[0027] The steering device provided by the present utility model can use the first hatch as the inlet for the material to enter the steering chamber, and the second hatch as the outlet for the material to be transported out of the steering chamber 1: The material is placed in a direction parallel to the conveying direction (in rows), enters the steering chamber from the first hatch, and continues to be conveyed in the steering chamber through the conveying roller assembly. When reaching the second hatch, the lifting mechanism jacks up the support plate, and the support plate jacks out from the gap between the roller rods and lifts the material off the roller rods. The material is separated from the roller rods and is no longer conveyed by the conveying roller assembly, and then is pushed out of the steering chamber by the push / pull mechanism from a direction perpendicular to the original conveying direction. At this time, the placement direction of the material remains unchanged, while the conveying direction becomes the push / pull direction perpendicular to the original conveying direction. Therefore, the material is placed in rows in the new conveying direction and enters the furnace in the next stage in rows, realizing the steering of the material in the roller hearth kiln.

[0028] The steering device of the present utility model can realize the material entering the steering chamber in rows from the replacement chamber, avoid the too wide hatch of the replacement chamber affecting the airtightness, and realize the steering of the sagger in the steering chamber. The material comes out of the steering chamber in rows and enters the furnace, meeting the requirement of the existing roller hearth kiln for feeding in rows.

[0029] The roller hearth kiln steering device provided by the present utility model can also use the second hatch as the inlet for the material to enter the steering chamber, and the first hatch as the outlet for the material to be transported out of the steering chamber: Initially, the lifting mechanism controls the support plate to jack out in the gap between the roller rods, so that the support plate is higher than the roller rods. Outside the second hatch, the material is placed in a direction perpendicular to the parallel opening direction of the second hatch (in rows). The push / pull mechanism pulls the material into the steering chamber from outside the second hatch, and the support plate supports the just-entered material. At this time, the placement direction of the material is the same as the conveying direction of the conveying roller assembly; then the lifting mechanism controls the support plate to descend below the roller path, and the original material on the support plate falls on the roller path. The conveying roller assembly conveys the material, and the material is placed in rows in the conveying direction. The material is sent out of the steering chamber from the first hatch and enters the next process in rows, realizing the steering of the material in the roller hearth kiln.

[0042] As shown in the attached Figure 1 - attached Figure 6 drawings, the present utility model includes a steering device for a roller kiln, which includes a steering chamber 1, a first chamber door 2, a second chamber door 3, a push / pull mechanism 4, and a material lifting assembly;

[0043] The first chamber door 2 and the second chamber door 3 are respectively arranged on adjacent side walls of the steering chamber 1, that is, the opening directions of the first chamber door 2 and the second chamber door 3 are perpendicular to each other; optionally, both the first chamber door 2 and the second chamber door 3 are provided with heat-insulating doors with good sealing performance, and are controlled to open and close by cylinders;

[0044] A conveying roller assembly is arranged in the steering chamber 1, and the conveying direction of the conveying roller assembly is the same as the opening direction of the first chamber door 2. Since the opening directions of the first chamber door 2 and the second chamber door 3 are perpendicular, the conveying direction of the conveying roller assembly is perpendicular to the opening direction of the second chamber door 3; inside the steering chamber 1, materials are transported by the rotation of the roller rods of the conveying roller assembly.

[0045] The material lifting component includes a support plate 13 disposed in the gap between the roller rods of the conveying roller assembly and a lifting mechanism 5 for driving the support plate 13 to lift and lower. The lifting mechanism 5 is disposed at the bottom of the support plate 13, and the support plate 13 is controlled by the lifting mechanism 5 to lift and lower in the gap between the roller rods. Specifically, when the lifting mechanism 5 controls the support plate 13 to lower so that the support plate 13 is lower than the roller rods, the material is supported by the roller rods at this time, and the material is normally transported under the rotation of the roller rods. When the lifting mechanism 5 controls the support plate 13 to rise so that the support plate 13 is higher than the upper ends of the roller rods, the support plate 13 lifts the material from the roller rods at this time, and the material is supported by the support plate 13, and the material is separated from the roller rods and no longer transported with the rotation of the roller rods.

[0046] The push / pull mechanism 4 is disposed on the side wall of the steering chamber 1 opposite to the second chamber door 3, and the push / pull direction of the push / pull mechanism 4 is perpendicular to the conveying direction of the conveying roller assembly, that is, the push / pull direction is the same as the opening direction of the second chamber door 3. The push / pull mechanism 4 can achieve linear driving in the horizontal direction.

[0047] Specifically, when the material is transported to align with the second chamber door 3, the lifting mechanism 5 controls the support plate 13 to rise, lifts the material from the roller rods, and then the push / pull mechanism 4 pushes / pulls the material into / out of the second chamber door 3, avoiding abrasion of the roller rods when the material moves along the axial direction of the roller rods, or damage caused by uneven axial force on the roller rods.

[0048] Preferably, the first chamber door 2 serves as the entrance for the material to enter the steering chamber 1, and the second chamber door 3 serves as the exit for the material to be transported out of the steering chamber 1. During operation: The materials are placed (in rows) in a direction parallel to the conveying direction of the conveying roller assembly, enter the steering chamber 1 from the first chamber door 2, and continue to be transported in the steering chamber 1 through the conveying roller assembly; when the material reaches the position aligned with the second chamber door 3, the lifting mechanism 5 raises the support plate 13, and the support plate 13 protrudes from the gap between the roller rods and lifts the material away from the roller rods, and the material is separated from the roller rods and is no longer transported by the conveying roller assembly; then the push / pull mechanism 4 pushes the material out of the second chamber door 3 from a direction perpendicular to the original conveying direction. At this time, since the placement direction of the material remains unchanged while the new conveying direction becomes the push / pull direction perpendicular to the original conveying direction, the placement direction of the material is perpendicular to the new conveying direction, and the materials are placed in rows in the new conveying direction and enter the processing device of the next process in rows from the second chamber door 3, realizing the steering of the materials in the roller hearth kiln, and the materials placed in rows can enter the next process in rows.

[0049] In the embodiment of the present invention, the first chamber door 2 of the steering device can be connected to the replacement chamber of the roller hearth kiln. The materials can be sent out from the replacement chamber in rows, avoiding the influence of too wide a chamber door of the replacement chamber on the airtightness. And through the steering of the saggers in the steering chamber 1, the materials come out of the steering chamber 1 in rows and enter the furnace, meeting the requirement of the existing roller hearth kiln for feeding in rows.

[0050] Optionally, the second bin door 3 serves as the inlet for materials to enter the diversion bin 1, and the first bin door 2 serves as the outlet for materials to be transported out of the diversion bin 1. During operation: Initially, the lifting mechanism 5 controls the support plate 13 to protrude from the gaps between the roller rods, making the support plate 13 higher than the roller rods; the materials outside the second bin door 3 are placed (in rows) in a direction perpendicular to the direction of the parallel opening of the second bin door 3. The pushing / pulling mechanism 4 pulls the materials from outside the second bin door 3 into the diversion bin 1, and the just-entered materials are supported by the support plate 13. At this time, the placement direction of the materials is the same as the conveying direction of the conveying roller assembly; then the lifting mechanism 5 controls the support plate 13 to descend below the roller path, and the materials originally on the support plate 13 fall onto the roller path. The conveying roller assembly conveys the materials, and the materials are placed in columns in the conveying direction. The materials are sent out of the diversion bin 1 through the first bin door 2 and enter the next process in columns.

[0051] In the diversion device of the embodiment of the present utility model, the pushing / pulling mechanism 4 perpendicular to the conveying direction of the conveying roller assembly pushes or pulls the materials from the side, so that the materials are diverted during transportation in the diversion bin, and the row direction of the materials relative to the moving direction changes, thereby realizing the diversion of the materials.

[0052] In a preferred embodiment, the support plate 13 includes a backing plate 131 and a plurality of bosses 132 provided on the backing plate 131; wherein, the bottom of the backing plate 131 is connected to the lifting mechanism 5, and the lifting mechanism 5 controls the lifting of the backing plate 131, thereby driving the simultaneous lifting of the plurality of bosses 132; each boss 132 aligns with the gap between the roller rods of the conveying roller assembly, and the width of the boss 132 is smaller than the width of the gap between the roller rods of the conveying roller assembly, ensuring that the boss 132 can lift out of the gap between the roller rods to lift the materials; optionally, the boss 132 can be a rib parallel to the installation direction of the roller rods, or a plurality of convex points can be provided along the installation direction of the roller rods in the gap between the roller rods. Preferably, a plurality of lifting mechanisms 5 are distributed at the bottom of the backing plate 131, and the plurality of lifting mechanisms 5 are synchronously lifted through the central control system, providing lifting drive at multiple places at the bottom of the backing plate 131, ensuring uniform force on each part of the backing plate 131, and avoiding uneven force on each part of the backing plate 131 under load and drive, resulting in the backing plate 131 not being able to maintain flatness, and the materials slipping or rolling on the uneven support surface, affecting transportation. Optionally, the lifting mechanism 5 is a cylinder.

[0053] In a preferred embodiment, the conveying roller assembly includes a first conveying part 11 and a second conveying part 12 arranged in sequence. The first conveying part 11 is close to the first bin door 2, and the second conveying part 11 is communicated with the first conveying part 12. The materials enter the first conveying part 11 from the first bin door 2 and then enter the second conveying part 12. The conveying directions of the first conveying part 11 and the second conveying part 12 are the same;

[0054] The first conveying part 11 is set as a non-powered roller path, including several non-powered roller rods 111 rotatably connected to the steering bin 1. The non-powered roller rods 111 are not connected to a driving mechanism. When the material enters the first conveying part 11, it moves on its own on the non-powered roller rods 111 under manual force or the inertia of the previous process. On the one hand: The roller path of the first conveying part 11 is connected to the roller path of the previous process. Setting the non-powered roller rods 111 can serve as a transition area between two driving roller paths, helping to smoothly transport the material, avoiding jams or impacts at the connection, thereby protecting the material and the equipment. And the non-powered roller rods 111 can play a buffering role, reducing the vibration and impact during the transfer of the material from one driving roller path to another, protecting the integrity of the material. The setting of the non-powered roller rods 111 can help adjust the conveying speed of the material. If the speeds are inconsistent between different driving roller paths, the non-powered roller path can serve as a speed adjustment area to ensure that the material enters the next driving roller path at an appropriate speed. On the other hand: Since the non-powered roller rods 111 do not have a complex driving system, the roller path structure design can be simplified, and potential safety hazards are also reduced. And these roller rods do not require electric drive, which can reduce energy consumption and the use of electrical equipment, lowering the overall system cost and maintenance expenses.

[0055] The second conveying part 12 is set as a driving roller path, including several rotating roller rods 121 rotatably connected to the steering bin 1 and a rotating driving mechanism 122 docked with the rotating roller rods 121. The rotating driving mechanism 122 drives the rotating roller rods 121 to rotate, driving the conveyance of the material. After the material passes through a certain length of non-powered roller path, it is buffered and speed-adjusted, and then regains drive in the second conveying part 12 to maintain the conveying state.

[0056] In a preferred embodiment, several ceramic wheels 1111 coaxial with the non-powered roller rods 111 are fixedly connected to each non-powered roller rod 111. The diameter of the ceramic wheels 1111 is larger than that of the non-powered roller rods 111 and smaller than the gap width of the non-powered roller rods 111, ensuring that each non-powered roller rod 111 can rotate normally, driving the ceramic wheels 1111 to rotate coaxially with the non-powered roller rods 111. And the diameter of the ceramic wheels 1111 is the same as that of the rotating roller rods 121, ensuring a smooth transition of the material between the first conveying part 11 and the second conveying part 12. The ceramic wheels 1111 have a low coefficient of friction, reducing the frictional force of the material on the non-powered roller rods 111, making it easier for the material to slide on the non-powered roller path, thereby improving the conveying efficiency. And the ceramic material has high hardness and wear resistance, which can significantly extend the service life of the roller rods, reducing the need for frequent replacement and maintenance. Optionally, the ceramic wheels 1111 are detachably connected to the non-powered roller rods 111, facilitating the replacement of the ceramic wheels 1111 after wear.

[0057] In an optional embodiment, in the first conveying part 11, a plurality of mounting seats 112 are provided on the side wall of the steering bin 1, and a guide sleeve 113 is provided on each mounting seat 112. The unpowered roller 111 is rotatably connected to the guide sleeve 113. After the material enters the first conveying part 11, the material moves by itself under artificial force or inertia, and the unpowered roller 111 supporting the material is driven to rotate, thereby reducing the resistance to the material's self-movement; at the same time, the guide sleeve 113 limits the unpowered roller 111 in the installation direction and the material conveying direction to prevent the roller from falling out and ensure its rotation stability.

[0058] In an optional embodiment, the rotation drive mechanism 122 includes a driving active shaft 1221 and a plurality of driving driven shafts 1222, one end of each driving driven shaft 1222 is meshed with the driving active shaft 1221, and the other end is connected to the rotating roller rod 121; the driving active shaft 1221 is perpendicular to the driving driven shaft 1222, and one end of the driving driven shaft 1222 is connected to the driving active shaft 1221 through a helical gear, a bevel gear or a synchronous belt; in this embodiment, one driving active shaft 1221 can drive all the rotating roller rods 121 to rotate synchronously, thereby reducing the number of power devices of the rotation drive mechanism 122, reducing costs, and ensuring that the rotation speeds of all the rotating roller rods 121 are synchronized. Optionally, a universal joint 1223 is also provided between the driving driven shaft 1222 and the rotating roller rod 121, so that a small angle can exist between the rotating roller rod 121 and the driving driven shaft 122, which can ensure the rotation stability of the rotating roller rod 121. Specifically, the rotation driving mechanism 122 further includes a rotation motor 1224 for driving the driving shaft 1221 to rotate.

[0059] In an optional embodiment, the conveying roller assembly further includes a support seat 14 disposed on one side of the steering bin 1, the support seat 14 includes a mounting frame 141 fixed to the side wall of the steering bin 1 and a plurality of rotating wheels 142 rotatably disposed on the mounting frame 141, and each two rotating wheels 142 form a group for supporting one end of a roller rod;

[0060] At least one end of each unpowered roller 111 is supported by two rotating wheels 142; preferably, one end of each unpowered roller 111 is rotatably arranged in the guide sleeve 113, and the other end is arranged on a set of rotating wheels 142, so that the unpowered roller 111 can be rotatably arranged in the steering bin 1; optionally, both ends of each unpowered roller 111 can be rotatably arranged on the support seat 14, so that the unpowered roller 111 can be rotatably arranged;

[0061] Each rotating roller 121 is supported by two rotating wheels 142 at at least one end. Preferably, at least the end on the same side as the second bin door 3 is supported by two rotating wheels 142. Preferably, one end of each rotating roller 121 is docked with the driving driven shaft 1222, and a driving force is applied at this end of the rotating roller 121 to cause the rotating roller 121 to rotate, and the other end is placed between the two rotating wheels 142 to cooperate in rotation. Optionally, one end of each rotating roller 121 is docked with the driving driven shaft 1222, and two rotating wheels 142 are also provided below this end for support. A driving force is applied to this section of the rotating roller 121 to cause the rotating roller 121 to rotate, and the other end is placed between the two rotating wheels 142 to cooperate in rotation.

[0062] The installation position of the rotating wheel 142 in the first conveying part 11 is slightly higher than the installation position of the rotating wheel 142 in the second conveying part 12. In cooperation with the mounting seat 112 and the guide sleeve 113 at the other end of the non-powered roller 111, the height of the ceramic wheel 1111 on the non-powered roller 111 is kept the same as the height of the rotating roller 121, so as to ensure the flatness of the roller path of the entire conveying roller assembly and enable the material to be transported smoothly.

[0063] Optionally, a fine-tuning assembly 143 is provided under each rotating wheel 142 for adjusting the height of the rotating wheel 142, thereby adjusting the levelness of the roller, so that the entire roller path is on a plane, thus ensuring the stable transportation of the material.

[0064] In this embodiment, the rotating roller 121 is directly placed on the two rotating wheels 142, and it is extremely convenient and fast to connect the other end of the rotating roller 121 to the rotation driving mechanism 122, and the rotation effect is good. Moreover, when the fine-tuning assembly 143 adjusts the levelness of the roller, the rotation driving mechanism 122 corresponding to the other end of the rotating roller 121 will also be adjusted accordingly. At this time, since the rotating roller 121 only cooperates with the two rotating wheels 142 below, when adjusting the height of the rotation driving mechanism 122, the rotating roller 121 has a large free movement space and there will be no interference or jamming, thus simplifying the difficulty of leveling the roller.

[0065] Moreover, at least the end of the rotating roller 121 on the same side as the second bin door 3 is supported by two rotating wheels 142, and there is no entity above or outside this end. Therefore, the material can be directly discharged from this end of the rotating roller 121, improving the diversity of feeding and discharging. At this time, the push / pull mechanism 4 can directly push or pull the material onto or off the rotating roller 121.

[0066] In an alternative embodiment, the push / pull mechanism 4 includes a horizontal linear drive 41 and a push / pull rod 42. One end of the push / pull rod 42 is connected to the output end of the horizontal linear drive 41, and the other end penetrates into the steering chamber 1 and is vertically provided with a push / pull plate 43, which is disposed opposite to the second chamber door 3. The horizontal linear drive 41 drives the push / pull rod 42 to move linearly in a direction perpendicular to the roller path transportation direction. The push / pull plate 43 at the end of the push / pull rod 42 pushes or pulls the material out of the second chamber door 3. By pushing or pulling perpendicular to the original transportation direction, the transportation direction of the material is changed, realizing the steering of the material. Optionally, the horizontal linear drive 41 includes a chassis 411, a linear module 412 and a connecting seat 413. The chassis 411 supports the linear module 412 to make the height of the linear module 412 match that of the conveyor roller assembly. The slide of the linear module 412 is set as the connecting seat 413. One end of the push / pull rod 42 is fixed on the connecting seat 413, so that the height of the push / pull plate 43 connected to the other end of the push / pull rod 42 matches the height of the material.
