Description

Technical Field

[0001] The invention relates to the technical field of kiln structures, and in particular to a kiln top hanging structure. Background Art

[0002] The traditional hanging structure kiln roof is mainly composed of hangers, furnace bricks, etc., among which the hangers are used to hang the furnace bricks on the furnace roof structure. At present, these hanging structures generally use the following methods to achieve the connection between furnace bricks and hangers:

[0003] 1. Welding connection: weld the hanger directly to the furnace brick. Although this method has a high connection strength, it requires cutting when replacing or repairing the furnace brick, which is cumbersome and inefficient. At the same time, thermal stress damage may be caused to the furnace brick during the welding process.

[0004] 2. Bolt fixing: Pre-embed bolt holes on the furnace bricks, and then use bolts to connect the hanger to the furnace bricks. Although this connection method is easy to disassemble, the threads may be difficult to disassemble due to high temperature corrosion after long-term use, and the presence of bolt holes may also cause the strength of the furnace brick structure to decrease.

[0005] 3. Hook connection: Process hook grooves on the furnace bricks, and then connect the sling to the furnace bricks through hooks. This method can achieve fast loading and unloading, but the manufacturing cost is increased because the hook grooves need to be processed on the furnace bricks, and the hooks are prone to wear or breakage after long-term use, affecting the safety and reliability of the hanging structure.

[0006] The above existing hanging structures are not only inconvenient to operate during installation and disassembly, but also have certain safety hazards in long-term use. For example, the connection methods of welding and bolt fixing are prone to fatigue, corrosion and other problems in high temperature environments; although the hook form solves the problem of loading and unloading, its structural design complicates the processing technology and increases the production cost. Therefore, in order to solve the above problems, it is necessary to develop a new hanging structure to improve the stability and safety of the kiln furnace top hanging structure, while simplifying the installation and maintenance process and reducing production costs.

[0050] In this embodiment, the furnace brick 1 is made of refractory material, and a through hole 101 is opened in the middle thereof. The through hole 101 is divided into two parts: a first hole section 102 and a second hole section 103. The first hole section 102 has a smaller diameter, and the second hole section 103 has a larger diameter, and a diameter-changing step 104 is formed between the two. Such a design enables the hanging column 2 to smoothly pass through the first hole section 102 and extend into the second hole section 103, and the diameter-changing step 104 plays a positioning role. The hanging column 2 can be made of a high-temperature resistant metal material, and when installed, it passes through the first hole section 102 and extends into the second hole section 103.

[0051] There are multiple suspension members 3, which are arranged on the circumferential side of the suspension column 2 along the radial direction of the suspension column 2 and can move relative to the suspension column 2. After moving, the suspension members 3 can abut against the diameter-changing step 104 and provide sufficient suspension force for the suspension bricks, thereby ensuring that the furnace bricks 1 are firmly suspended on the suspension column 2. Due to the design of movable suspension members 3, the installation and disassembly process becomes simpler and faster. The close contact between the suspension members 3 and the furnace bricks 1 provides a good support effect for the furnace bricks 1, reducing the risk of falling off. There is no need to additionally process a complex hook and groove structure on the furnace bricks 1, simplifying the production process and reducing costs.

[0052] Furthermore, the hanging column 2 is rotatably arranged relative to the furnace brick 1, and has an abutment portion 201, the abutment portion 201 is located below the suspension member 3, the abutment portion 201 has a first guide groove 202, the first guide groove 202 is arc-shaped, and also includes: a guide plate 4, the guide plate 4 is rotatably arranged on the hanging column 2 relative to the hanging column 2, and is located above the suspension member 3, the guide plate 4 has a second guide groove 401, the suspension member 3 has a first guide portion 301 and a second guide portion 302, the first guide portion 301 and the second guide portion 302 are respectively slidably arranged in the first guide groove 202 and the second guide groove 401.

[0053] In this embodiment, an abutment portion 201 is provided at the lower end of the suspension column 2, and the abutment portion 201 is located below the suspension member 3 and has a plurality of arc-shaped first guide grooves 202. The guide plate 4 is located above the suspension member 3 and is rotatably arranged relative to the suspension column 2, that is, when the suspension column 2 rotates, the abutment portion 201 of the suspension column 2 follows the rotation, while the guide plate 4 does not follow the rotation. A second guide groove 401 is provided on the guide plate 4, which cooperates with the first guide groove 202 on the suspension column 2. The suspension member 3 has a first guide portion 301 and a second guide portion 302, and the two guide portions are respectively slidably arranged in the first guide groove 202 and the second guide groove 401 to facilitate the sliding of the suspension member 3.

[0054] Through the cooperation between the guide plate 4 and the first guide groove 202 and the second guide groove 401 on the suspension column 2, the position of the suspension member 3 can be accurately adjusted, thereby improving the stability and safety of the hanging structure. The design of the guide plate 4 enables the operator to easily adjust the position of the suspension member 3, and installation and disassembly can be completed without complicated tools. The coordinated structure of the guide plate 4 and the suspension column 2 is compact, does not occupy additional space, and is conducive to improving the space utilization inside the kiln.

[0055] Furthermore, it also includes: a hanging tube 5, which is lifted and lowered on the hanging column 2, and the hanging tube 5 has a spiral guide groove 501, which is arranged on the inner wall of the hanging tube 5 along the height direction of the hanging tube 5; the hanging column 2 has a guide block 203, and the guide block 203 is slidably set in the spiral guide groove 501; a thermal insulation fiber 6, which is set at an end of the second hole section 103 away from the first hole section 102, and is used to block part of the second hole section 103, and the unblocked second hole section 103 above the thermal insulation fiber 6 is a hanging support space 7, and the abutment portion 201 is located in the hanging support space 7, and is used to abut against the upper part of the thermal insulation fiber 6.

[0056] In this embodiment, a spiral guide groove 501 is provided on the inner wall of the hanging tube 5, and the spiral guide groove 501 is arranged along the height direction of the hanging tube 5. A guide block 203 is provided on the hanging column 2, and the guide block 203 is slidably arranged in the spiral guide groove 501 of the hanging tube 5, so as to realize the lifting and lowering movement of the hanging tube 5 relative to the hanging column 2. The heat insulation fiber 6 is arranged at one end of the second hole section 103 away from the first hole section 102, and is used to block part of the second hole section 103. The unblocked second hole section 103 located above the heat insulation fiber 6 is called the hanging support space 7. The abutment portion 201 is located in the hanging support space 7, and is used to abut against the upper part of the heat insulation fiber 6 to prevent the high temperature from damaging the hanging column 2.

[0057] Furthermore, the guide plate 4 has an insertion rod 402, the hanging tube 5 has a socket 502, the insertion rod 402 is inserted into the socket 502, the length of the socket 502 is greater than the length of the insertion rod 402, and the hanging tube 5 is moved closer to or away from the guide plate 4 after being raised or lowered; and further comprising:

[0058] The outer cylinder 8 is arranged on the guide plate 4 and is located above the guide plate 4 . The diameter of the outer cylinder 8 is the same as the diameter of the guide plate 4 . The hanging cylinder 5 is located inside the outer cylinder 8 .

[0059] In this embodiment, at least one insertion rod 402 is provided on the guide plate 4. Preferably, two or more insertion rods 402 can be provided. The main function of the insertion rod 402 is to connect the hanging tube 5. A hole 502 is provided on the hanging tube 5. The length of the hole 502 is greater than the length of the insertion rod 402 on the guide plate 4, allowing the hanging tube 5 to move up and down relative to the guide plate 4. The guide plate 4 is stably fixed by the hanging tube 5 and will not rotate with the rotation of the hanging column 2, thereby improving the stability of the suspension member 3 during movement.

[0060] Furthermore, the suspension member 3 has a suspension portion 303 and a support portion 304. The support portion 304 is arc-shaped and has a plurality of strip grooves 305. The plurality of strip grooves 305 are arranged on the outside of the support portion 304 parallel to the height direction of the support portion 304, and are used to abut against the arc-shaped radial inner wall of the suspension space 7. The suspension portion 303 is located on one side of the support portion 304, and is used to abut against the axial inner wall of the suspension space 7; the abutting portion 201 has an arc-shaped protrusion, and the arc-shaped protrusion is used to abut against the upper part of the thermal insulation fiber 6.

[0061] In this embodiment, the suspension member 3 has two parts: a suspension part 303 and a support part 304. The support part 304 is an arc-shaped structure, and a plurality of strip grooves 305 are provided on its outer side, and these strip grooves 305 are arranged parallel to the height direction of the support part 304. The arc-shaped design of the support part 304 matches the arc-shaped radial inner wall of the suspension space 7. The design of the strip grooves 305 increases the contact friction between the support part 304 and the inner wall of the suspension space 7, and improves the stability. The suspension part 303 is located on one side of the support part 304, and is used to abut against the axial inner wall of the suspension space 7, further enhancing the stability of the suspension member 3. The abutment part 201 is located at the lower end of the suspension column 2, and has an arc-shaped protrusion. The arc-shaped protrusion is used to abut against the upper part of the thermal insulation fiber 6, providing a positioning function for the suspension member 3. During the specific installation, one end of the abutting portion 201 can be inserted into the second hole section 103 until it abuts against the upper part of the thermal insulation fiber 6. At this time, the suspension tube 5 is further moved, and the rotation of the suspension rod can be achieved by lifting and lowering the suspension tube 5. The arc-shaped protrusion not only provides a positioning effect, but also reduces the resistance to rotation, so that the rotation process is carried out more smoothly, and further makes the opening and contraction process of several suspension members 3 more stable.

[0062] Furthermore, the first hole section 102 is conical, the diameter of the outer cylinder 8 is smaller than the diameter of the narrow end of the first hole section 102, and an accommodating space 9 is formed between the outer cylinder 8, the guide plate 4 and the side wall of the first hole section 102, and also includes: a thermal insulation member 10, which is arranged in the accommodating space 9.

[0063] In this embodiment, the first hole section 102 is now designed to be conical, with its narrow end facing the second hole section 103 and its wide end facing the outer cylinder 8. The thermal insulation member 10 is arranged in the accommodating space 9 formed between the outer cylinder 8, the guide plate 4 and the side wall of the first hole section 102, so as to improve the thermal insulation performance of the overall structure.

[0064] Furthermore, the furnace bricks 1 are provided in plurality, and the plurality of furnace bricks 1 are arranged in an alternating pattern. One side of the furnace brick 1 has an arc-shaped connecting portion 105 , and the other side has an arc-shaped connecting groove 106 . Insulating fibers 6 are also provided between the arc-shaped connecting portion 105 and the arc-shaped connecting groove 106 .

[0065] In this embodiment, a plurality of furnace bricks 1 are arranged at intervals. Each furnace brick 1 has an arc-shaped connecting portion 105 on one side and an arc-shaped connecting groove 106 on the other side. Insulating fibers 6 are also arranged between the arc-shaped connecting portions 105 and the arc-shaped connecting grooves 106 of adjacent furnace bricks 1 to further improve the thermal insulation performance of the overall structure. The arc-shaped connection method enhances the connection stability between the furnace bricks 1, and by arranging additional insulating fibers 6 at the connection between adjacent furnace bricks 1, heat transfer can be effectively reduced, further protecting the suspension column 2 and the suspension support 3 from high temperature damage, and extending the service life.

[0066] Furthermore, it also includes: a track 11, which is arranged above the hanging tube 5, and the track 11 has a hanging hole 1101, and the hanging holes 1101 are arranged along the length direction of the track 11; a hanging member 12, the hanging member 12 is rotatably sleeved on the upper part of the hanging column 2, and the hanging member 12 has a bearing part 1201, and the bearing part 1201 is slidably abutted with the track 11 on both sides of the hanging hole 1101; a connecting member 13, the connecting member 13 has a plurality of connecting holes 1301, each connecting hole 1301 is provided with a hanging tube 5, and adjacent hanging tubes 5 are connected by the connecting member 13; a frame 14, and the connecting member 13 is lifted and lowered on the frame 14.

[0067] In this embodiment, the track 11 is arranged above the hanging tube 5, and the track 11 has a hanging hole 1101, and the hanging hole 1101 is arranged along the length direction of the track 11; the hanging member 12 is rotatably sleeved on the upper part of the hanging column 2, and the hanging member 12 has a bearing part 1201, and the bearing part 1201 is slidably abutted with the upper part of the track 11 on both sides of the hanging hole 1101, and the connecting member 13 has a plurality of connecting holes 1301, and a hanging tube 5 is arranged in each connecting hole 1301, and adjacent hanging tubes 5 are connected by the connecting member 13. The connecting member 13 is lifted and lowered on the frame 14, and the frame 14 is used to support the entire hanging system, and realize the lifting and lowering of the connecting member 13 through an appropriate driving device.

[0068] Working principle: Taking a single installation as an example, first install the guide plate 4 on the side of the suspension column 2 close to the abutment portion 201, and install a plurality of suspension supports 3 between the guide plate 4 and the abutment portion 201 (the first guide portion 301 and the second guide portion 302 are respectively slidably arranged in the first guide groove 202 and the second guide groove 401). Preferably, the distance from the lower end of the abutment portion 201 to the lower end of the guide plate 4 is equal to the height of the suspension space 7, so that when the abutment portion 201 is fully abutted against the upper part of the thermal insulation fiber 6, the guide plate 4 is located at one end of the narrow part of the first hole section 102, so that the space of the accommodating space 9 is more flat, making it more convenient and efficient to place the thermal insulation member 10.

[0069] The hanging tube 5 is installed on the outside of the hanging column 2, so that the guide block 203 on the hanging column 2 is slidably set in the spiral guide groove 501 of the hanging tube 5, and the outer tube 8 is sleeved on the outside of the hanging tube 5 and installed above the guide plate 4. The main function of the outer tube 8 is to make the space of the accommodating space 9 more flat. If the outer tube 8 is not set, a large number of gaps will be generated at the connection between the guide plate 4 and the hanging tube 5. The interval between the guide plate 4 and the hanging tube 5 is not fixed, and is located in the first hole section 102 during installation. Therefore, it is not convenient to add the thermal insulation part 10 after installation, and the operation is difficult, so the outer tube 8 is set.

[0070] Then, the installed suspension column 2 assembly of other structures is passed through the first hole section 102 of the furnace brick 1, so that the abutment portion 201 extends into the suspension support space 7 and abuts against the upper part of the thermal insulation fiber 6, driving the suspension cylinder 5 to descend. There can be multiple driving methods. For example, during a single installation, the suspension cylinder 5 can be lifted and lowered by workers, tool carts or driving devices.

[0071] During the descent of the hanging tube 5, it is necessary to keep the hanging tube 5 itself from rotating. During the descent of the hanging tube 5, the abutting portion 201 will be driven to further abut against the upper part of the thermal insulation fiber 6 to ensure stable abutment. At this time, the hanging column 2 no longer moves in the height direction. With the sliding cooperation of the spiral guide groove 501 of the hanging tube 5 and the guide block 203 of the hanging column 2, the hanging column 2 rotates relative to the hanging tube 5, that is, the abutting portion 201 and the guide plate 4 rotate relative to each other. Driven by the relative rotation, several suspension members 3 move and unfold along the radial direction of the suspension column 2. After unfolding, the hanging portion 303 of the suspension member 3 abuts against the axial inner wall of the suspension space 7, and the supporting portion 304 abuts against the arc-shaped radial inner wall of the suspension space 7.

[0072] It is worth noting that the prerequisite step for placing the thermal insulation member 10 in the accommodating space 9 is to first move and expand a plurality of support members 3 so that they can abut against the arc-shaped radial inner wall of the support space 7. The advantage brought by the stable abutment of the support members 3 is that the centering of the suspension column 2 is achieved - that is, a plurality of circularly arranged support members 3 are moved to abut against the arc-shaped inner wall, so that the suspension column 2 can be located at the center position of the first hole section 102, which has a centering effect and effectively avoids the problem of uneven placement of the thermal insulation member 10 on the peripheral side of the outer cylinder 8 due to the skewed placement of the suspension column 2, thereby affecting the normal thermal insulation effect.

[0073] Furthermore, the hanging member 12 is installed on the upper end of the hanging column 2, and the hanging column 2 can rotate freely relative to the hanging member 12. After the hanging member 12 passes through the hanging hole 1101, the hanging member 12 is rotated so that the hanging member 12 is perpendicular to the hanging hole 1101. The bearing part 1201 is pressed on the track 11 on both sides of the hanging hole 1101, and can slide along the track 11 to adjust the position of the furnace brick 1 on the top of the kiln. The hanging member 12 and the track 11 can be fixed by fasteners, such as pins, bolts, etc.

[0074] The above is a single installation process. In order to further improve the efficiency of assembly and disassembly, a connector 13 is designed. The connector 13 can connect multiple hanging tubes 5 in a column or a row. Through the connector 13, not only can the positions of multiple hanging tubes 5 be adjusted synchronously, but also the lifting and lowering of the hanging tubes 5 can be driven synchronously, so as to realize the synchronous removal of a row or a column, thereby improving the efficiency of assembly and disassembly. The frame 14 can be provided with an installation position according to the actual use of the kiln, and a driving device can be installed to drive the lifting and lowering of the connector 13. When the space and temperature are such that the driving device cannot be used, a conventional fixing method can be adopted, such as providing multiple fixing grooves, and the staff can use fasteners to fasten. At the same time, by Figure 1 It can be seen that the furnace brick 1 used in this embodiment is divided into two parts, the upper part and the lower part. The size of the lower part is larger than that of the upper part. In the above scheme, it is known that the lower part is filled with thermal insulation fibers, and the larger gap in the upper part also needs to be placed with thermal insulation components, such as precast blocks of casting materials, to improve the thermal insulation effect. In order to more clearly show the structure in this embodiment, the precast blocks of casting materials are not reflected in the figure, so they are explained here.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
