Description

Technical Field

[0001] This invention belongs to the field of kilns, specifically relating to a feeding and unloading system, a kiln system, and a sealed continuous feeding and unloading method thereof. Background Technology

[0002] A kiln is a furnace that uses a vacuum environment and a protective atmosphere to heat materials for protective firing. The furnace body contains a protective gas and high temperature.

[0003] To improve thermal energy utilization, continuous firing kilns exist that can continuously fire items. During firing, material is continuously fed from one end and discharged from the other, with conveyor devices, such as roller conveyors, installed inside. However, the feeding and discharging processes inevitably connect the kiln to the external environment, leading to atmosphere and heat loss. This increases energy consumption and allows outside air to enter the kiln, causing oxidation of the items and affecting firing quality.

[0004] Therefore, there is an urgent need for a material loading and unloading structure that can achieve continuous firing of materials while preventing heat loss from the kiln and external gases from entering the kiln. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a material feeding system, a kiln system and a sealed continuous material feeding method thereof.

[0006] This invention provides a loading and unloading system, including a transition furnace body and a transition furnace loading and unloading device;

[0007] The transition furnace body has openings at both ends, one of which has a first furnace door and the other has a second furnace door for connecting and separating the transition furnace body and the kiln.

[0008] The transition furnace feeding and discharging device includes a first furnace door feeding and discharging mechanism and a second furnace door feeding and discharging mechanism;

[0009] The first furnace door feeding and discharging mechanism is used to move materials into and / or out of the transition furnace body from the opening on the side of the first furnace door when the first furnace door is open and the second furnace door is closed.

[0010] The second furnace door feeding and discharging mechanism includes a linear drive mechanism, a connecting rod disposed on the output end of the linear drive mechanism, and a material push-pull block disposed on the end of the connecting rod. The first furnace door is provided with a sliding hole, the connecting rod is slidably disposed on the sliding hole, and the material push-pull block is located inside the first furnace door. The linear drive mechanism is used to drive the material push-pull block to move in the transition furnace body when the first furnace door is closed and the second furnace door is open, so as to move the material into and / or out of the transition furnace body from the opening on the side of the second furnace door.

[0011] Furthermore, the connecting rod and the sliding hole are in a sliding sealing fit.

[0012] Furthermore, the material push-pull block is equipped with a material fitting mechanism, which is used to connect the material push-pull block with the material, thereby pulling the material into / out of the transition furnace body.

[0013] Furthermore, the material fitting mechanism includes a fitting block and a fitting block drive mechanism;

[0014] The interlocking block is movable on the material push-pull block;

[0015] The interlocking block drive mechanism includes a transmission mechanism, a drive rod, and a drive mechanism. The drive mechanism is located on the output end of the linear drive mechanism. One end of the drive rod is connected to the drive mechanism, and the other end extends into the inside of the first furnace door through a sliding hole and is connected to the transmission mechanism.

[0016] The drive mechanism drives the drive rod to move, and the drive rod drives the transmission mechanism to move the mating block.

[0017] Furthermore, the second furnace door feeding and discharging mechanism also includes a first furnace door opening and closing mechanism, with the first furnace door located at the output end of the first furnace door opening and closing mechanism;

[0018] The direction of movement of the first furnace door opening and closing mechanism is parallel to the direction of movement of the linear drive mechanism.

[0019] Furthermore, the loading and unloading system also includes a bracket and a support platform that is movable along the X direction on the bracket;

[0020] The first furnace door opening and closing mechanism and the linear drive mechanism are mounted on the support platform, and both the first furnace door opening and closing mechanism and the linear drive mechanism move along the Y direction;

[0021] The first furnace door feeding and discharging mechanism includes a material carrying platform set on a support platform and a material push-pull component that can move along the Y direction on the material carrying platform;

[0022] The Y-direction is parallel to the axis of the transition furnace body.

[0023] Furthermore, the loading and unloading system also includes a loading and unloading device located on one side of the support frame;

[0024] The loading and unloading device includes a conveying mechanism and a push-pull material mechanism. The push-pull material mechanism is used to move materials from the material carrier platform to the conveying mechanism, and / or to move materials from the conveying mechanism to the material carrier platform.

[0025] The present invention also provides a kiln system, including a kiln as described above with a loading and unloading system;

[0026] The transition furnace body in the loading and unloading system is connected to the kiln through the opening on the second furnace door side;

[0027] The second furnace door is used to connect and separate the transition furnace body and the kiln.

[0028] Furthermore, this kiln system also includes a vacuuming device and / or a gas filling device. The vacuuming device is used to evacuate the transition furnace body, and the gas filling device is used to fill the transition furnace body with protective gas.

[0029] The present invention also provides a kiln sealing continuous feeding and unloading method, using the above-mentioned kiln system, including a kiln sealing feeding mode and / or a kiln sealing unloading mode;

[0030] The sealed feeding mode of the kiln includes the following steps:

[0031] S11, controls the second furnace door to close and the first furnace door to open;

[0032] S12, the material is moved into the transition furnace body through the first furnace door feeding and discharging mechanism;

[0033] S13, control the first furnace door to close, so that the transition furnace body is sealed, and open the vacuum device and / or gas filling device to vacuum and / or fill the transition furnace body with protective gas;

[0034] S14, When the vacuum or atmosphere inside the transition furnace meets the requirements, control the second furnace door to open, so that the transition furnace body is connected to the kiln.

[0035] S15 controls the linear drive mechanism to move, driving the connecting rod and material push-pull block to move. The material push-pull block pushes the material in the transition furnace into the kiln. Then the linear drive mechanism resets and controls the second furnace door to close, completing the kiln sealing and feeding.

[0036] Repeating steps S11-S15 allows for continuous feeding of materials into a sealed kiln.

[0037] The kiln sealed feeding mode includes the following steps:

[0038] S21, control the first furnace door and the second furnace door to close, so that the furnace body of the transition furnace is in a sealed state, and open the vacuuming device and / or gas filling device to vacuum and / or fill the furnace body of the transition furnace with protective gas.

[0039] S22, When the vacuum or atmosphere inside the transition furnace meets the requirements, control the second furnace door to open, so that the transition furnace body is connected to the kiln.

[0040] S23 controls the linear drive mechanism to move, driving the connecting rod and material push-pull block to move. The material push-pull block pulls the material in the kiln into the transition furnace body, and then controls the second furnace door to close.

[0041] S24, control the opening of the first furnace door, and move the material out of the transition furnace body through the first furnace door feeding and discharging mechanism to complete the sealing and feeding of the kiln;

[0042] Repeating steps S21-S24 allows for continuous material feeding into a sealed kiln.

[0043] The beneficial effects of the present invention are as follows: The loading and unloading system provided by the present invention has the following beneficial effects:

[0044] 1. This loading and unloading system can be set up at the loading end of the kiln as a loading device or at the unloading end of the kiln as a unloading device. One set can be used as both a loading and unloading device, which greatly reduces research and development and production costs. In addition, this loading and unloading system can also switch the order of actions to adapt to the movement direction of the kiln and switch the loading and unloading direction of the kiln, thereby improving its adaptability.

[0045] Second, by setting up a transition furnace body with two furnace doors and a transition furnace feeding and discharging device, the kiln can always be in a sealed state for feeding and discharging operations, thereby avoiding the loss of vacuum or leakage of protective gas in the kiln during the feeding and discharging operations. When the kiln requires a high-temperature environment, heat loss can also be avoided, thereby reducing the energy loss of the kiln.

[0046] Third, the location of the second furnace door feeding and discharging mechanism serves several purposes. First, it facilitates the configuration, assembly, and maintenance of the mechanism. Second, the entire operation of the second furnace door feeding and discharging mechanism does not affect the transfer of materials between the transition furnace body and the kiln, nor does it affect the opening and closing of the second furnace door. Third, the linear drive mechanism of the second furnace door feeding and discharging mechanism is located outside the transition furnace body, away from the harsh environment inside the transition furnace body and the kiln. This reduces the performance requirements of the linear drive mechanism, thereby lowering costs and increasing its service life.

[0047] Fourth, the sliding engagement of the connecting rod and sliding hole in the second furnace door's feeding and discharging mechanism serves two purposes. Firstly, it allows the connecting rod to move synchronously with the opening and closing of the first furnace door, maintaining their relative positions. Secondly, the sliding hole acts as an intermediate support structure for the connecting rod, transforming its cantilevered structure into a two-point support structure. During top-loading and pulling operations, this changes to a three-point support structure: the end of the connecting rod connects to the material, the middle part slides through the sliding hole, and the other end is fixedly connected to the output end of the linear drive mechanism. This improves the structural stability of the connecting rod in all states, meaning the first furnace door not only functions as the furnace door but also as a support and guide structure for the connecting rod. Furthermore, the connecting rod supplements the sliding hole, ensuring the sealing performance of the first furnace door and enabling material pushing and pulling even when the first furnace door is closed.

[0060] As attached Figure 1 -Appendix Figure 6 As shown, the present invention provides a feeding and unloading system, including a transition furnace body 5 and a transition furnace feeding and unloading device, wherein the filter furnace body 5 is used for the transition of material 7 relative to the kiln 8 for feeding or unloading.

[0061] The transition furnace body 5 has openings at opposite ends, one of which has a first furnace door 51 and the other has a second furnace door 52 for connecting and separating the transition furnace body 5 and the kiln 8; a moving platform 53 is preferably provided inside the transition furnace body 5 for carrying the material 7 to stay and slide inside the transition furnace body 5.

[0062] The transition furnace feeding and discharging device includes a first furnace door feeding and discharging mechanism 3 and a second furnace door feeding and discharging mechanism 4. The first furnace door feeding and discharging mechanism 3 is used to complete the feeding and discharging of material 7 relative to the transition furnace body 5 on the side of the first furnace door 51. The second furnace door feeding and discharging mechanism 4 is used to complete the feeding and unloading of material 7, which is equivalent to the loading and unloading of kiln 8. In this way, this feeding and unloading system can complete the continuous feeding and unloading operation of kiln 8 in a sealed state. That is, this feeding and unloading system can be set at the feeding end of kiln 8 as a feeding device and at the unloading end of kiln 8 as a unloading device. One set can be used as both a feeding device and an unloading device, which greatly reduces the research and development and production costs. In addition, this feeding and unloading system can also switch the feeding and unloading direction of kiln 8 by switching the action sequence, thereby adapting to the movement direction of kiln 8 and switching the feeding and unloading direction of kiln 8, improving adaptability.

[0063] The first furnace door feeding and discharging mechanism 3 is used to move material 7 from the opening on the side of the first furnace door 51 into and / or out of the transition furnace body 5 when the first furnace door 51 is open and the second furnace door 52 is closed. During the process of moving material 7 from the opening on the side of the first furnace door 51 into and / or out of the transition furnace body 5, the second furnace door 52 is in a closed state, separating the transition furnace body 5 from the kiln 8, which can maintain the sealed state of the kiln 8.

[0064] The second furnace door feeding and discharging mechanism 4 includes a material pushing and pulling mechanism 42. The material pushing and pulling mechanism 42 includes a linear drive mechanism 421, a connecting rod 422 disposed on the output end of the linear drive mechanism 421, and a material pushing and pulling block 423 disposed on the end of the connecting rod 422. A sliding hole 511 is provided on the first furnace door 51. The connecting rod 422 is slidably disposed on the sliding hole 511 and the material pushing and pulling block 423 is located inside the first furnace door 51. The linear drive mechanism 421 is used to drive the material pushing and pulling block 423 to move within the transition furnace body 5 when the first furnace door 51 is closed and the second furnace door 52 is open, so as to move the material 7 from the opening on the side of the second furnace door 52 into and / or out of the transition furnace body 5. When material 7 moves into the transition furnace body 5 through the opening on the second furnace door 52, it is to transfer the material 7 inside the kiln 8 onto the transition furnace body 5, completing the feeding of the kiln 8. When material 7 moves out of the transition furnace body 5 through the opening on the second furnace door 52, it is to transfer the material 7 inside the transition furnace body 5 into the kiln 8, completing the feeding of the kiln 8. During the process of material 7 moving into and / or out of the transition furnace body 5 through the opening on the second furnace door 52, the first furnace door 51 is in a closed state, thereby ensuring that the kiln 8 is also in a sealed state, preventing external gas from flowing into the kiln 8. In addition, the second furnace door feeding and discharging mechanism 4 is located on one side of the first furnace door 51, away from the second furnace door 52 and the kiln 8. On the one hand, this facilitates the configuration, assembly and maintenance of the second furnace door feeding and discharging mechanism 4. On the other hand, the entire operation of the second furnace door feeding and discharging mechanism 4 will not affect the transfer of material 7 between the transition furnace body 5 and the kiln 8, nor will it affect the opening and closing of the second furnace door 52. Furthermore, the linear drive mechanism 421 of the second furnace door feeding and discharging mechanism 4 is located outside the transition furnace body 5, away from the harsh environment inside the transition furnace body 5 and the kiln 8. This can reduce the performance requirements of the linear drive mechanism 421, thereby reducing costs and increasing the service life of the linear drive mechanism 421.

[0065] The loading and unloading system provided by this invention has the following beneficial effects:

[0066] 1. This loading and unloading system can be set at the loading end of the kiln 8 as a loading device or at the unloading end of the kiln 8 as a unloading device. One set can be used as both a loading and unloading device, which greatly reduces research and development and production costs. In addition, this loading and unloading system can also switch the loading and unloading direction of the kiln 8 by switching the action sequence, thereby adapting to the movement direction of the kiln 8 and changing the loading and unloading direction of the kiln 8, thus improving adaptability.

[0067] Second, by setting up a transition furnace body 5 with two furnace doors and a transition furnace feeding and discharging device, the kiln 8 can always be in a sealed state for feeding and discharging operations, thereby avoiding the loss of vacuum or leakage of protective gas in the kiln 8 during the feeding and discharging operations. When the kiln 8 requires a high-temperature environment, heat loss can also be avoided, thereby reducing the energy loss of the kiln 8.

[0068] Third, the location of the second furnace door feeding and discharging mechanism 4 is advantageous in several ways. First, it facilitates the configuration, assembly, and maintenance of the second furnace door feeding and discharging mechanism 4. Second, the entire operation of the second furnace door feeding and discharging mechanism 4 will not affect the transfer of material 7 between the transition furnace body 5 and the kiln 8, nor will it affect the opening and closing of the second furnace door 52. Furthermore, the linear drive mechanism 421 of the second furnace door feeding and discharging mechanism 4 is located outside the transition furnace body 5, away from the harsh environment inside the transition furnace body 5 and the kiln 8. This reduces the performance requirements of the linear drive mechanism 421, thereby reducing costs and increasing the service life of the linear drive mechanism 421.

[0069] Fourth, in the second furnace door feeding / discharging mechanism 4, the connecting rod 422 and the sliding hole 511 are slidably engaged. On the one hand, this allows the connecting rod 422 to move synchronously with the opening and closing of the first furnace door 51, maintaining their relative positions. On the other hand, the sliding hole 511 also serves as an intermediate support structure for the connecting rod 422, transforming the originally cantilevered connecting rod 422 into a two-point support structure. During the top-loading and pulling operations, this changes to a three-point support structure where the end of the connecting rod 422 is connected to the material, the middle end is slidably connected to the sliding hole 511, and the other end is fixedly connected to the output end of the linear drive mechanism 421. This improves the structural stability of the connecting rod 422 in all states. In other words, the first furnace door 51 not only serves as the furnace door but also as a support and guide structure for the connecting rod 422. Furthermore, the connecting rod 422 can also supplement the sliding hole 511, ensuring the sealing performance of the first furnace door 51 and enabling the pushing and pulling of materials when the first furnace door 51 is closed.

[0070] In one embodiment, the connecting rod 422 and the sliding hole 511 are in sliding sealing cooperation, which can ensure the sealing effect of the first furnace door 51 on the transition furnace body 5, and ensure the sealing effect inside the transition furnace body 5 when both the first furnace door 51 and the second furnace door 52 are closed, and ensure the sealing effect of the kiln 8 when the first furnace door 51 is closed and the second furnace door 52 is open.

[0071] In one embodiment, the material push-pull block 423 is provided with a material fitting mechanism. The material fitting mechanism is used to connect the material push-pull block 423 with the material 7, thereby pulling the material 7 into / out of the transition furnace body 5. That is, the material fitting mechanism is used to complete the detachable connection between the material push-pull block 423 and the material 7, so as to facilitate the pulling of the material 7 from the kiln 8 into the transition furnace body 5.

[0072] In one embodiment, the material fitting mechanism includes a fitting block 4231 and a fitting block driving mechanism 4232;

[0073] The interlocking block 4231 is movably mounted on the material push-pull block 423, and the material 7 is correspondingly provided with a mating groove 71. The movement of the interlocking block 4231 can allow the interlocking block 4231 to be embedded into the mating groove 71, thereby completing the connection between the material push-pull block 423 and the material 7, or allow the interlocking block 4231 to be disengaged from the mating groove 71, thereby completing the separation between the material push-pull block 423 and the material 7.

[0074] The interlocking block drive mechanism 4232 includes a transmission mechanism, a drive rod 42321 and a drive mechanism 42322. The drive mechanism 42322 is set on the output end of the linear drive mechanism 421. One end of the drive rod 42321 is connected to the drive mechanism 42322, and the other end extends into the inside of the first furnace door 51 through the sliding hole 511 and is connected to the transmission mechanism.

[0075] The drive mechanism 42322 drives the drive rod 42321 to move, and the drive rod 42321 drives the transmission mechanism to move the mating block 4231. In this embodiment, the drive mechanism 42322 of the mating block drive mechanism 4232 is located on the outside of the transition furnace body 5, away from the harsh environment inside the transition furnace body 5 and the kiln 8, which can reduce the performance requirements of the drive mechanism 42322, thereby reducing costs and increasing the service life of the drive mechanism 42322.

[0076] In one specific embodiment, the material push-pull block 423 further includes an abutment plate 4233, which is directly fixed to the end of the connecting rod 422. The abutment plate 4233 can be moved by the drive of the linear drive mechanism 421, thereby pushing the material 7 to move.

[0077] The mating block 4231 is slidably mounted on the abutment plate 4233 or the connecting rod 422. The transmission mechanism preferably uses a gear 42323 and a rack 42324. The rack 42324 is fixed to the upper mating block 4231, and the gear 42323 is fixed to the drive rod 42321. The drive mechanism 42322 is a rotary drive mechanism used to drive the drive rod 42321 to rotate. The rotation of the drive rod 42321 drives the gear 42323 to rotate, which in turn drives the rack 42324 to move linearly, thereby causing the mating block 4231 to slide linearly, completing the engagement and separation with the material 7. It should be noted that the transmission mechanism can also use chain drive or worm gear transmission, etc., depending on the actual needs.

[0078] In one preferred embodiment, when the interlocking block driving mechanism 4232 drives the interlocking block 4231 to engage with the mating groove 71 of the material 7, the abutment plate 4233 abuts against the side wall of the material 7. At this time, the abutment plate 4233 and the interlocking block 4231 can clamp the material 7, thereby achieving double fixation of the material 7. When the material 7 is relatively heavy and the sliding plane of the moving platform 53 inside the transition furnace body 5 is smooth, inertial slippage during the pushing and pulling process of the material 7 can be effectively avoided, improving the pushing stability.

[0079] In one embodiment, the second furnace door feeding and discharging mechanism 4 further includes a first furnace door opening and closing mechanism 41, and the first furnace door 51 is disposed at the output end of the first furnace door opening and closing mechanism 41;

[0080] The moving direction of the first furnace door opening and closing mechanism 41 is parallel to the moving direction of the linear drive mechanism 421. In this embodiment, the opening and closing direction of the first furnace door 51 is consistent with the moving direction of the connecting rod 422. At this time, the opening and closing action of the first furnace door 51 will not affect the second furnace door feeding and discharging mechanism 4, and the action of the second furnace door feeding and discharging mechanism 4 will not affect the opening and closing of the first furnace door 51. Preferably, the moving directions of the linear drive mechanism 421 and the first furnace door opening and closing mechanism 41 are parallel to the axis of the transition furnace body 5.

[0081] In one embodiment, the loading and unloading system further includes a bracket 1 and a support platform 2 that is movable along the X direction on the bracket 1. Preferably, the movement of the support platform 2 is automatic rather than manual. Specifically, a first X-direction driving member 21 is provided on the bracket 1, and the output end of the first X-direction driving member 21 is connected to the support platform 2 to drive the support platform 2 to move along the X direction.

[0082] The first furnace door opening and closing mechanism 41 and the linear drive mechanism 421 are mounted on the support platform 2, and both the first furnace door opening and closing mechanism 41 and the linear drive mechanism 421 move along the Y direction, that is, the first furnace door opening and closing mechanism 41 and the linear drive mechanism 421 move synchronously with the support platform 2.

[0083] The first furnace door feeding and discharging mechanism 3 includes a material carrying platform 31 set on the support platform 2 and a material pusher / puller 32 that can move along the Y direction on the material carrying platform 31. The material carrying platform 31 is used to carry material 7, and the material pusher / puller 32 is used to push the material 7 located on the material carrying platform 31 into the transition furnace body 5 along the Y direction, or to pull the material 7 from the transition furnace body 5 into the material carrying platform 31, thereby completing the feeding and unloading of material 7 at the first furnace door 51 position of the transition furnace body 5.

[0084] The Y-direction is parallel to the axis of the transition furnace body 5. In this embodiment, the operation of the first furnace door feeding / discharging mechanism 3 and the opening and closing operation of the first furnace door 51 are linked through the support platform 2. That is, when the support platform 2 is moved so that the material carrying platform 31 in the first furnace door feeding / discharging mechanism 3 is aligned with the transition furnace body 51, the first furnace door 51 simultaneously leaves the opening of the transition furnace body 5 to make room for the material carrying platform 31. When the first furnace door 51 is aligned with the opening of the transition furnace body 5, the material carrying platform 31 returns to its initial position. This allows the loading and unloading of material 7, the opening and closing of the first furnace door 51, the removal of the first furnace door 51 to expose the opening of the transition furnace body 5, and the alignment of material 7 with the opening of the transition furnace body 5 to be performed simultaneously. This can improve the efficiency of feeding and discharging, and material 7 can be pushed out of the transition furnace body 5 from the opening on the other side of the transition furnace body 5 when the first furnace door 51 is closed.

[0085] In one embodiment, the loading and unloading system further includes a loading and unloading device 6 disposed on one side of the support 1. The loading and unloading device 6 is used to load and unload the first furnace door loading and unloading mechanism 3, specifically to load and unload the material carrying platform 31 in the initial position.

[0086] The loading and unloading device 6 includes a conveying mechanism 61 and a push-pull material mechanism 62. The conveying mechanism 61 is a belt conveyor, roller conveyor or plate conveyor. The conveying mechanism 61 can transport the material 7 to the next station or from the previous station to the material carrier platform 31. The push-pull material mechanism 62 is used to move the material 7 from the material carrier platform 31 to the conveying mechanism 61 and / or move the material 7 from the conveying mechanism 61 to the material carrier platform 31.

[0087] The present invention also provides a kiln system, including a kiln 8 as described above with a loading and unloading system;

[0097] S14, When the vacuum or atmosphere inside the transition furnace 5 meets the requirements, that is, when the working environment of the transition furnace 5 is consistent with the working environment inside the kiln 8, control the second furnace door 52 to open so that the transition furnace 5 and the kiln 8 are connected.

[0098] S15, control the linear drive mechanism 421 to move, drive the connecting rod 422 and the material push-pull block 423 to move, the material push-pull block 423 pushes the material 7 in the transition furnace body 5 into the kiln 8, then the linear drive mechanism 421 resets, controls the second furnace door 52 to close, and completes the kiln sealing and feeding.

[0099] Repeating steps S11-S15 allows for continuous feeding of materials into a sealed kiln.

[0100] The kiln sealed feeding mode includes the following steps:

[0101] S21, control the first furnace door 51 and the second furnace door 52 to close, so that the transition furnace body 5 is in a sealed state, and open the vacuum device and / or gas filling device to vacuum and / or fill the transition furnace body 5 with protective gas, so that the working environment of the transition furnace body 5 is consistent with the working environment inside the kiln 8.

[0102] S22, When the vacuum or atmosphere inside the transition furnace body 5 meets the requirements, control the second furnace door 52 to open, so that the transition furnace body 5 is connected to the kiln 8.

[0103] S23, control the linear drive mechanism 421 to move, drive the connecting rod 422 and the material push-pull block 423 to move, the material push-pull block 423 pulls the material 7 in the kiln 8 into the transition furnace body 5, and then control the second furnace door 52 to close, so as to avoid affecting the working environment of the kiln 8 during the material feeding process.

[0104] S24, control the opening of the first furnace door 51, and move the material 7 out of the transition furnace body 5 through the first furnace door feeding and discharging mechanism 3 to complete the kiln sealing and feeding;

[0105] Repeating steps S21-S24 allows for continuous material feeding into a sealed kiln.
