Description

Technical Field

[0001] This utility model belongs to the field of brick production technology, and more specifically, it relates to a brick-pulling propulsion device for a calcining furnace. Background Technology

[0002] In the production of sheet bricks, the calcining furnace plays a crucial role in the high-temperature calcination of the bricks. Since the sheet bricks need to pass through multiple process temperature zones within the furnace, including preheating, high-temperature calcination, heat preservation, and cooling, each zone corresponds to a specific temperature range and processing time. To ensure that the sheet bricks can completely undergo these necessary heat treatment stages, the calcining furnace must be long enough to accommodate these sequentially arranged temperature zones. Therefore, large calcining furnaces that meet the requirements of the complete calcination process are often designed to be quite long, some even reaching tens of meters.

[0003] In existing calcining furnace brick-pulling technology, a lifting device is typically used to first lift all the bricks off the furnace's support surface, then move them along a predetermined direction to achieve position adjustment and material conveying. However, this method faces a significant technical challenge: to ensure continuous and stable material conveying, a large number of bricks need to be arranged inside the furnace. Their own weight, combined with the material they carry, means the lifting device must withstand an enormous total gravity. Working under this immense load for extended periods causes key load-bearing components of the lifting device (such as the lifting cylinders and support beams) to easily deform and experience accelerated wear. This not only shortens the device's lifespan but also leads to problems such as inconsistent lifting heights and deviations in the brick movement trajectory, severely disrupting the stable operation of the calcination process and even posing a potential risk of equipment failure or safety accidents due to component failure. Utility Model Content

[0004] To address the problem that bricks need to be lifted during the pushing process, this invention proposes a brick-pushing device for calcining furnaces to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a brick-pulling device for a calcining furnace, including a calcining furnace. The calcining furnace is equipped with a placement component inside. The placement component has several placement ends. The bottom of the placement end is equipped with a moving component. Both ends of the calcining furnace are equipped with sealing components. One end of the calcining furnace is equipped with a pushing component. The pushing component is connected to the sealing component. The top of the calcining furnace is equipped with positioning components corresponding to the several placement ends.

[0007] The placement component is used to support the brick, and the pushing component is used to push the placement component so that the moving component drives the brick to move inside the calcining furnace through the placement component.

[0008] Furthermore, the placement assembly includes a guide frame, which is provided on both sides of the inner wall of the calcining furnace. A placement plate is movably connected inside the guide frame, and multiple placement plates are sequentially arranged inside the guide frame. A placement groove is opened on the top of the placement plate, and several support rods are fixedly connected to the inner wall of the placement groove.

[0009] Furthermore, the moving component includes support legs, multiple of which are fixedly connected to the bottom of the placement plate, and a rotating roller is rotatably connected between two corresponding support legs, the rotating roller contacting the bottom of the inner wall of the calcining furnace.

[0010] Furthermore, the sealing assembly includes a sealing door, which is rotatably connected to the calcining furnace. A handle and a fixing rod are fixedly connected to one side of the sealing door. A locking frame is movably connected to the outer surface of the fixing rod. Locking frames are fixedly connected to the top and bottom of the calcining furnace, and the locking frame is movably connected to the locking frame.

[0011] Furthermore, the pushing assembly includes a pushing hydraulic cylinder, which is fixedly installed on one side of the sealing door. The output end of the pushing hydraulic cylinder passes through the sealing door and is fixedly connected to a pushing disc. A pulling frame is fixedly connected to one side of the placement plate, and the pulling frame contacts the other side of the next placement plate.

[0012] Furthermore, the positioning component includes positioning holes, a plurality of which are provided on the top of the guide frame, the positioning holes penetrate the placement plate, and a positioning rod is movably connected inside the positioning holes.

[0013] Furthermore, a lifting plate is provided on the top of the calcining furnace, the top end of the positioning rod passes through the lifting plate and is fixedly connected to a connecting plate, a spring is fixedly connected between the bottom of the connecting plate and the top of the lifting plate, an installation frame is fixedly installed on the top of the calcining furnace, a lifting hydraulic cylinder is fixedly installed on the top of the installation frame, and the lifting end of the lifting hydraulic cylinder passes through the installation frame and is fixedly connected to the lifting plate.

[0014] This utility model has the following beneficial effects:

[0015] This invention places the pull-plate bricks on the placement assembly and moves the placement assembly into the calcining furnace using a moving assembly. At this point, all the placement assemblies inside the calcining furnace are in contact with each other. When it is necessary to push the pull-plate bricks on the placement assembly, the pushing assembly only needs to move the first placement assembly to move all the placement assemblies together. The moving assembly also makes the movement of the placement assemblies smooth. The above design effectively avoids the problem in traditional methods where the pushing assembly has to directly overcome the huge weight of all the components and materials, significantly reducing the risk of equipment overload damage.

[0016] This invention uses a hydraulic cylinder to drive a lifting plate downwards, causing the connecting plate to overcome spring tension and simultaneously lift all positioning rods until they disengage from the positioning holes. At this point, the placement plate can move freely within the guide frame. After displacement, the hydraulic cylinder resets, and the bottom of the positioning rod descends with the lifting plate until it contacts the top surface of the placement plate. Simultaneously, the spring accumulates reset potential energy through the connecting plate. When the placement plate reaches the preset position, the positioning rods automatically align with the positioning holes, and the spring immediately releases its stored energy to drive the positioning rods to precisely insert into the positioning holes, achieving instantaneous self-locking of the placement plate. This design ensures that once the placement plate reaches the predetermined position, it will not continue to move under the influence of the rotating rollers.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a brick-pulling device for a calcining furnace, including a calcining furnace 1. The calcining furnace 1 is equipped with a placement component 2 inside. The placement component 2 has several placement ends. The bottom of the placement end is equipped with a moving component 3. Both ends of the calcining furnace 1 are equipped with sealing components 4. One end of the calcining furnace 1 is equipped with a pushing component 5, which is connected to the sealing component 4. The top of the calcining furnace 1 is equipped with positioning components 6 corresponding to several placement ends.

[0030] The placement component 2 is used to support the brick, and the pushing component 5 is used to push the placement component 2 so that the moving component 3 can move the brick inside the calcining furnace 1 through the placement component 2.

[0031] By placing the calcined bricks inside the placement component 2 and moving the placement component 2 inside the calcination furnace 1, the moving component 3 can support the bricks through the placement component 2. During the pushing operation, the pushing component 5 can push the first placement component 2, so that the placement component 2 can push the next placement component 2 under the support of the moving component 3, and thus complete the pushing of all placement components 2. At the same time, the bricks on all placement components 2 have also completed the pushing operation.

[0032] By placing the pull plate bricks on the placement component 2 and moving the placement component 3 to the inside of the calcining furnace 1, all the placement components 2 inside the calcining furnace 1 are in contact end to end. When it is necessary to push the pull plate bricks on the placement component 2, the pushing component 5 only needs to move the first placement component 2 to move all the placement components 2 together. At the same time, the setting of the moving component 3 makes the movement of the placement components 2 relatively smooth. The above settings effectively avoid the problem that the pushing component 5 has to directly overcome the huge weight of all components and materials in the traditional method, and significantly reduce the risk of equipment overload damage.

[0033] In one embodiment, the placement component 2 includes a guide frame 201, which is provided on both sides of the inner wall of the calcining furnace 1. A placement plate 202 is movably connected inside the guide frame 201. Multiple placement plates 202 are sequentially arranged inside the guide frame 201. A placement groove 203 is opened on the top of the placement plate 202, and a number of support rods 204 are fixedly connected to the inner wall of the placement groove 203.

[0034] By placing the pull plate brick on top of several support rods 204, the placement plate 202 supports the pull plate brick through the support rods 204. The support rods 204 expose most of the bottom of the pull plate brick, resulting in more uniform heating of the surface of the pull plate brick during subsequent calcination. Then, the placement plate 202 is moved into the calcination furnace 1 and can be moved into the guide frame 201. At this time, the guide frame 201 can support and guide the placement plate 202, resulting in higher stability when the placement plate 202 moves the pull plate brick.

[0035] In one embodiment, the moving component 3 includes a support leg 301, a plurality of support legs 301 are fixedly connected to the bottom of the placement plate 202, and a rotating roller 302 is rotatably connected between two corresponding support legs 301, the rotating roller 302 being in contact with the bottom of the inner wall of the calcining furnace 1.

[0036] After the placement plate 202 moves into the guide frame 201, the rotating roller 302 at the bottom of the support leg 301 contacts the bottom of the inner wall of the calcining furnace 1. This arrangement allows the support leg 301 to support the placement plate 202 through the rotating roller 302. At the same time, since the rotating roller 302 can rotate at the bottom of the inner wall of the calcining furnace 1 when pushing the placement plate 202, the entire pushing process is relatively labor-saving. Meanwhile, the rotating roller 302 is connected to the support leg 301 through a high-temperature bearing, so that the rotating roller 302 can rotate normally on the support leg 301 in a high-temperature environment.

[0037] In one embodiment, the sealing assembly 4 includes a sealing door 401, which is rotatably connected to the calcining furnace 1. A handle 402 and a fixing rod 403 are fixedly connected to one side of the sealing door 401. A locking frame 404 is movably connected to the outer surface of the fixing rod 403. Locking frames 405 are fixedly connected to the top and bottom of the calcining furnace 1. The locking frame 404 is movably connected to the locking frame 405.

[0038] By pushing the locking frame 404, the locking frame 405 can move under the guidance of the fixing rod 403. After the locking frame 404 moves out from inside the locking frame 405, the sealing door 401 is rotated by the handle 402, so that the sealing door 401 no longer blocks the port of the calcining furnace 1. The locking mechanism of the sealing door 401 by the locking frame 405 and the locking frame 404 ensures that the connection between the two is relatively firm when the sealing door 401 blocks the port of the calcining furnace 1.

[0039] In one embodiment, the material pushing assembly 5 includes a material pushing hydraulic cylinder 501, which is fixedly installed on one side of the sealing door 401. The output end of the material pushing hydraulic cylinder 501 passes through the sealing door 401 and is fixedly connected to a material pushing plate 502. A pulling frame 503 is fixedly connected to one side of the placement plate 202, and the pulling frame 503 contacts the other side of the next placement plate 202.

[0040] After the placement plate 202 is moved into the calcining furnace 1, the pull frame 503 on one side of the placement plate 202 can contact the side of the previous pull frame 503. When it is necessary to push the pull plate brick on the placement plate 202, the pusher hydraulic cylinder 501 is driven. The pusher hydraulic cylinder 501 pushes the first placement plate 202 through the pusher plate 502. The first placement plate 202 then pushes the next placement plate 202 through the pull frame 503. The pull frame 503 makes it convenient to move the placement plate 202 out of the calcining furnace 1.

[0041] In one embodiment, the positioning component 6 includes a positioning hole 601. Several positioning holes 601 are provided on the top of the guide frame 201. The positioning holes 601 penetrate the placement plate 202. A positioning rod 602 is movably connected inside the positioning hole 601.

[0042] Once the placement plates 202 have been moved to their designated positions, the positioning rod 602 can move downwards and directly into the positioning hole 601 on the placement plate 202. At this time, the positioning rod 602 can position the placement plate 202 through the positioning hole 601, so that the bricks on the placement plate 202 will not move arbitrarily during the calcination process.

[0043] In one embodiment, for the calcining furnace 1 described above, a lifting plate 603 is provided on the top of the calcining furnace 1, the top end of the positioning rod 602 passes through the lifting plate 603 and is fixedly connected to a connecting plate 604, a spring 605 is fixedly connected between the bottom of the connecting plate 604 and the top of the lifting plate 603, an mounting bracket 606 is fixedly installed on the top of the calcining furnace 1, a lifting hydraulic cylinder 607 is fixedly installed on the top of the mounting bracket 606, and the lifting end of the lifting hydraulic cylinder 607 passes through the mounting bracket 606 and is fixedly connected to the lifting plate 603.

[0044] By driving the lifting hydraulic cylinder 607, the lifting plate 603 can move the positioning rods 602 upward via the spring 605 and connecting plate 604, causing all the positioning rods 602 to move out of the corresponding positioning holes 601. At this time, the placement plate 202 can move inside the guide frame 201. When the pushing hydraulic cylinder 501 starts to push the placement plate 202, the lifting hydraulic cylinder 607 can be driven. At this time, the lifting plate 603 moves downward and resets under the push of the lifting hydraulic cylinder 607, so that the bottom end of the positioning rod 602 is aligned with the top end of the placement plate 202. When the parts are in contact, the positioning rod 602 pulls the spring 605 upward through the connecting plate 604; after the pushing end of the hydraulic cylinder 501 moves to its maximum stroke, the positioning rods 602 can be aligned vertically with the corresponding positioning holes 601. At this time, since the bottom end of the positioning rod 602 is not supported, the spring 605 can pull the positioning rod 602 downward through the connecting plate 604, and the positioning rod 602 can automatically move into the interior of the positioning hole 601; the above settings enable the positioning rod 602 to automatically complete the positioning of the placement plate 202 after the placement plate 202 is moved to the predetermined position.

[0045] Through the above technical solution, 1. By placing the pull-plate bricks on the placement component 2 and moving the placement component 3 to the inside of the calcining furnace 1, all the placement components 2 inside the calcining furnace 1 are in contact end to end. When it is necessary to push the pull-plate bricks on the placement component 2, the pushing component 5 only needs to move the first placement component 2 to move all the placement components 2 together. At the same time, the setting of the moving component 3 makes the movement of the placement components 2 relatively smooth. The above setting effectively avoids the problem that the pushing component 5 has to directly overcome the huge weight of all components and materials in the traditional method, and significantly reduces the risk of equipment overload damage; 2. By driving The lifting hydraulic cylinder 607 drives the lifting plate 603 to press down, causing the connecting plate 604 to overcome the tension of the spring 605 and simultaneously lift all the positioning rods 602 until they disengage from the positioning hole 601. At this time, the placement plate 202 can move freely within the guide frame 201. After the displacement is completed, the lifting hydraulic cylinder 607 resets, and the bottom end of the positioning rod 602 descends with the lifting plate 603 until it contacts the top surface of the placement plate 202. At the same time, the spring 605 accumulates reset potential energy through the connecting plate 604. When the placement plate 202 reaches the preset position, the positioning rod 602 automatically aligns with the positioning hole 601, and the spring 605 immediately releases its stored energy to drive the positioning rod 602 to accurately insert into the positioning hole 601, achieving instantaneous self-locking of the placement plate 202. The above settings ensure that after the placement plate 202 moves to the predetermined position, it will not continue to move under the drive of the rotating roller 302.
