Description

Technical Field

[0001] This invention relates to the field of lime kiln technology, and more specifically, to a corner ring protection device and its manufacturing method. Background Technology

[0002] A lime kiln is used to calcine limestone to produce quicklime. The process of a lime kiln is as follows: limestone and fuel are loaded into the lime kiln and preheated to 850 degrees Celsius to begin decomposition. Calcination is completed at 1200 degrees Celsius. After cooling, the limestone is unloaded from the kiln, thus completing the production of quicklime.

[0003] The corner ring is one of the main components of a lime kiln that withstands high temperatures during calcination. Refractory bricks are installed on both the upper and lower parts of the working surface of the corner ring, protecting the lime kiln. However, the non-working surface of the corner ring lacks any protective structure. As a result, the corner ring is easily oxidized by the high-temperature airflow inside the lime kiln during the high-temperature calcination process, reducing its service life. Summary of the Invention

[0004] In view of this, the present invention proposes a corner ring protection device, aiming to solve the problem that the lack of a protective structure on the non-working surface of the corner ring in the prior art easily reduces its service life. The present invention also proposes a method for manufacturing the corner ring protection device.

[0005] In one aspect, the present invention provides a corner ring protection device, the device comprising: a plurality of anchors spaced apart on the non-working surface of the corner ring; a protective plate laid on the non-working surface of the corner ring to cover the non-working surface of the corner ring; and a casting component disposed on the side of the protective plate away from the corner ring, wherein each anchor is placed inside the casting component.

[0006] Furthermore, in the aforementioned corner ring protection device, the protective plate is a ceramic fiber plate, which is bonded to the non-working surface of the corner ring.

[0007] Furthermore, in the aforementioned corner ring protection device, each anchor is welded to the non-working surface of the corner ring.

[0008] Furthermore, in the aforementioned corner ring protection device, each anchor is coated with a protective layer.

[0009] Furthermore, in the aforementioned corner ring protection device, the casting component is formed by supporting a mold on one side of the protection plate and pouring casting material into the mold. After the casting material reaches a preset strength, the mold is removed. Each anchor is placed in the casting material, and the casting material is in contact with the side of the protection plate away from the corner ring.

[0010] Furthermore, in the aforementioned corner ring protection device, each anchor includes: a straight section, which is disposed on the non-working surface of the corner ring; and two inclined sections, which are connected one-to-one with the two ends of the straight section, and the two inclined sections have a preset included angle.

[0011] Furthermore, in the aforementioned corner ring protection device, each inclined segment is designed to be wavy.

[0012] Furthermore, the aforementioned corner ring protection device also includes: multiple L-shaped connectors, the first end of each connector being perpendicularly connected to the non-working surface of the corner ring, the second end of each connector being parallel to the non-working surface of the corner ring and having a preset distance; the protection plate having multiple through holes, the through holes being inserted into the connectors, and the protection plate being sandwiched between the second end of the connector and the non-working surface of the corner ring.

[0013] In this invention, multiple anchors are spaced apart on the non-working surface of the corner ring, a protective plate is laid on the non-working surface of the corner ring, and the casting material places each anchor inside it, which can provide protection for the non-working surface of the corner ring and play a role in heat insulation of the exterior of the corner ring. This prevents the corner ring from being oxidized by the high-temperature airflow in the lime kiln during the high-temperature calcination process, thus extending the service life of the corner ring and solving the problem that the non-working surface of the corner ring in the prior art is not equipped with a protective structure, which easily reduces the service life.

[0014] On the other hand, the present invention also proposes a method for manufacturing a corner ring protection device, the method comprising the following steps: a setting step, wherein multiple anchors are set at intervals on the non-working surface of the corner ring; a laying step, wherein a protective plate is laid on the non-working surface of the corner ring; a coating step, wherein a protective layer is coated on each anchor; a casting step, wherein a mold is erected on the outside of the protective plate, and casting material is poured into the mold; wherein the casting material is in contact with the protective plate, and each anchor is placed in the casting material; and a removal step, wherein the mold is removed after the casting material reaches a preset strength.

[0015] Furthermore, in the above-mentioned method for manufacturing the corner ring protection device, in the laying step, the protective plate is a ceramic fiber board; and / or, in the coating step, the protective layer is asphalt; and / or, in the casting step, the casting material is refractory castable.

[0016] In this invention, multiple anchors are spaced apart on the non-working surface of the corner ring, and a protective plate is laid on the non-working surface of the corner ring. Casting material is poured on the outside of the protective plate, which can protect the non-working surface of the corner ring and play a role in heat insulation of the exterior of the corner ring. This prevents the corner ring from being oxidized by the high-temperature airflow in the lime kiln during the high-temperature calcination process, thus extending the service life of the corner ring.

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Device Example:

[0023] See Figure 1 and Figure 2 The figure shows a preferred structure of the corner ring protection device in this embodiment. As shown, the corner ring protection device includes: multiple anchors 1, a protective plate 2, and a casting component 3. The multiple anchors 1 are spaced apart on the non-working surface 41 of the corner ring 4. Specifically, the number of anchors 1 can be determined according to actual conditions, and this embodiment does not impose any limitation on this. The multiple anchors 1 are spaced apart on the non-working surface 41 of the corner ring 4, and the anchors 1 are staggered. Preferably, each anchor 1 is welded to the non-working surface 41 of the corner ring 4.

[0024] More preferably, each anchor 1 is coated with a protective layer, which may be asphalt.

[0025] The protective plate 2 is laid on the non-working surface 41 of the corner ring 4 to cover the non-working surface 41 of the corner ring 4. Specifically, after multiple anchors 1 are installed, the protective plate 2 is laid on the parts of the non-working surface 41 of the corner ring 4 where no anchors 1 are installed.

[0026] Preferably, the protective plate 2 is a ceramic fiber board, which is bonded to the non-working surface 41 of the corner ring 4.

[0027] The casting component 3 is located on the side of the protective plate 2 away from the corner ring 4, and each anchor 1 is placed inside the casting component 3. Specifically, the casting component 3 is formed by supporting a mold on one side of the protective plate 2 and pouring casting material into the mold. After the casting material reaches a preset strength, the mold is removed. Each anchor 1 is placed in the casting material, and the casting material is in contact with the side of the protective plate 2 away from the corner ring 4.

[0028] In practice, after welding multiple anchors 1, a protective plate 2 is laid on the non-working surface 41 of the corner ring 4. Then, a mold is erected on the side of the protective plate 2 away from the corner ring 4, and each anchor 1 is placed inside the mold. Then, castable material is poured into the mold. After the castable material reaches the preset strength, the mold is removed, thus forming the cast part 3, which contacts the side of the protective plate 2 away from the corner ring 4.

[0029] As can be seen, in this embodiment, multiple anchors 1 are spaced apart on the non-working surface 41 of the corner ring 4, the protective plate 2 is laid on the non-working surface 41 of the corner ring 4, and the casting component 3 places each anchor 1 inside it, which can provide protection for the non-working surface 41 of the corner ring 4, and play the role of heat insulation for the outside of the corner ring 4. This avoids the corner ring 4 being oxidized by the high-temperature airflow in the lime kiln during the high-temperature calcination process, and extends the service life of the corner ring 4. This solves the problem that the non-working surface of the corner ring in the prior art is not equipped with a protective structure, which easily reduces the service life.

[0030] See Figure 1 and Figure 2 In the above embodiments, each anchor 1 may include a straight section 11 and two inclined sections 12. The straight section 11 is disposed on the non-working surface 41 of the corner ring 4; specifically, the straight section 11 is welded to the non-working surface 41 of the corner ring 4. The straight section 11 has a preset length, which can be determined according to actual conditions; this embodiment does not impose any limitation on this. Preferably, the preset length is 10mm to 20mm to increase the contact area between the anchor 1 and the non-working surface 41 of the corner ring 4, ensuring a stable connection between the anchor 1 and the non-working surface 41 of the corner ring 4, and preventing separation between the anchor 1 and the non-working surface 41 of the corner ring 4.

[0031] The two inclined segments 12 correspond one-to-one with the two ends of the straight segment 11, and each inclined segment 12 is connected to the corresponding end of the straight segment 11, thus forming a trapezoidal structure between the two inclined segments 12 and the straight segment 11.

[0032] The two inclined segments 12 are separated by a preset angle α, which can be determined according to the actual situation. This embodiment does not impose any restrictions on this. Preferably, the two inclined segments 12 are arranged symmetrically with respect to the center of the straight segment 11.

[0033] Preferably, each inclined segment 12 is set to a wavy shape. Figure 2 The structure shown can effectively improve the bonding force between the anchor 1 and the cast material. The structure is simple and easy to implement. Specifically, the wave shape of each inclined segment 12 has a preset bending amplitude. By setting the bending amplitude, the undulation amplitude of the wave shape is determined, which further increases the contact area between the anchor 1 and the cast material, thereby ensuring the effective bonding between the anchor 1 and the cast material.

[0034] In specific implementation, the vertical distance L between the end of each inclined segment 12 away from the straight segment 11 and the straight segment 11, the diameter φ of the inclined segment 12, and the preset included angle α between the two inclined segments 12 can all be selected according to design requirements. This embodiment does not impose any restrictions on the specific values.

[0035] As can be seen, in this embodiment, each anchor 1 has a simple structure and is easy to implement.

[0036] In the above embodiments, the corner ring 4 protection device may further include: a plurality of connectors (not shown in the figure). Each connector is L-shaped, with its first end perpendicularly connected to the non-working surface 41 of the corner ring 4, and its second end parallel to the non-working surface 41 of the corner ring 4. Furthermore, there is a preset distance between the second end of each connector and the non-working surface 41 of the corner ring 4. This preset distance can be determined according to actual conditions, and this embodiment does not impose any restrictions on it.

[0037] In practice, the number of connectors can be determined according to the actual situation, and this embodiment does not impose any restrictions on this. Each connector is spaced apart on the non-working surface 41 of the corner ring 4.

[0038] The protective plate 2 has multiple through holes that pass through the connectors. The protective plate 2 is sandwiched between the second end of the connector and the non-working surface 41 of the corner ring 4. Specifically, the protective plate 2 has through holes corresponding to each connector, so the number of through holes is the same as the number of connectors, and each through hole corresponds one-to-one with each connector. Each through hole on the protective plate 2 passes through the corresponding connector, and the protective plate 2 is laid on the non-working surface 41 of the corner ring 4, while simultaneously being sandwiched within the gap between the second end of each connector and the non-working surface 41 of the corner ring 4.

[0039] In practice, the distance between the second end of each connector and the non-working surface 41 of the corner ring 4 is equal to the thickness of the protective plate 2.

[0040] As can be seen, in this embodiment, by setting multiple connectors on the non-working surface 41 of the corner ring 4, and clamping the protective plate 2 in the gap between the second end of the connector and the non-working surface 41 of the corner ring 4, the connector positions the protective plate 2, preventing the protective plate 2 from detaching from the non-working surface 41 of the corner ring 4, thus ensuring the stable installation of the protective plate 2.

[0041] In summary, in this embodiment, multiple anchors 1 are spaced apart on the non-working surface 41 of the corner ring 4, the protective plate 2 is laid on the non-working surface 41 of the corner ring 4, and the casting component 3 places each anchor 1 inside it, which can provide protection for the non-working surface 41 of the corner ring 4, and play a role in heat insulation of the exterior of the corner ring 4. This prevents the corner ring 4 from being oxidized by the high-temperature airflow in the lime kiln during the high-temperature calcination process, extends the service life of the corner ring 4, and solves the problem that the non-working surface of the corner ring in the prior art is prone to reduced service life due to the lack of a protective structure.

[0042] Method Implementation Examples:

[0043] This embodiment also proposes a method for manufacturing a corner ring protection device, see [link to documentation]. Figure 3 The manufacturing method of this corner ring protection device includes the following steps:

[0044] In step S1, multiple anchors are installed at intervals on the non-working surface of the corner ring.

[0045] Specifically, see Figure 1 Each anchor 1 is welded to the non-working surface 41 of the corner ring 4. In specific implementation, the spacing between each anchor 1 on the non-working surface 41 of the corner ring 4 can be determined according to design requirements; this embodiment does not impose any restrictions on this. After the anchor welding is completed, the welding quality is checked one by one to ensure that each anchor is firmly welded.

[0046] In specific implementation, the structure of the anchor can be referred to the description of the above device embodiment, and will not be repeated here.

[0047] Step S2: Lay a protective plate on the non-working surface of the corner ring.

[0048] Specifically, see Figure 1 After setting multiple anchors 1, a protective plate 2 is laid on the non-working surface 41 of the corner ring 4 where no anchors 1 are set, so that the protective plate 2 covers the non-working surface 41 of the corner ring 4.

[0049] Preferably, the protective plate is a ceramic fiber board, which is bonded to the non-working surface of the corner ring.

[0050] In practice, the ceramic fiberboard should be inspected to prevent it from falling off.

[0051] In specific implementation, the structure and installation of the protective plate can be referred to the description of the above device embodiment, and will not be repeated here.

[0052] Step S3 involves applying a protective layer to each anchor.

[0053] Specifically, the protective layer is asphalt. Asphalt is applied to each anchor 1. After the asphalt is applied, each anchor 1 is checked to see if it meets the requirements. If it meets the requirements, the subsequent operation continues. If it does not meet the requirements, each anchor 1 is welded again and coated again.

[0054] In the pouring step S43, a mold is set up on the outside of the protective plate, and the pouring material is poured into the mold; wherein the pouring material is in contact with the protective plate, and each anchor is placed in the pouring material.

[0055] Specifically, after the coating is applied, a mold and scaffold are erected on the non-working surface 41 of the protective plate 2 away from the corner ring 4. After the mold is erected, a comprehensive safety inspection is carried out on the mold and scaffold to ensure that the casting mold and scaffold can withstand the weight of the casting material before finally carrying out the casting construction.

[0056] Preferably, the casting material is a refractory castable.

[0057] In practice, the ceramic fiberboard should be inspected again before pouring the refractory material to prevent individual sections of the ceramic fiberboard from falling off.

[0058] Step S5: After the poured material reaches the preset strength, remove the mold.

[0059] Specifically, the preset strength can be determined according to the actual situation, and this embodiment does not impose any restrictions on it. After the mold and scaffolding are removed, the construction of the non-working surface of the diagonal ring is completed.

[0060] Preferably, in the laying step, the protective plate is a ceramic fiber board; and / or, in the coating step, the protective layer is asphalt; and / or, in the casting step, the casting material is refractory castable.

[0061] As can be seen, in this embodiment, multiple anchors are spaced apart on the non-working surface of the corner ring, and a protective plate is laid on the non-working surface of the corner ring. Casting material is poured on the outside of the protective plate, which can provide protection for the non-working surface of the corner ring and play a role in heat insulation of the exterior of the corner ring. This prevents the corner ring from being oxidized by the high-temperature airflow in the lime kiln during the high-temperature calcination process, thus extending the service life of the corner ring.

[0062] It should be noted that the corner ring protection device and its manufacturing method in this invention are based on the same principle, and related aspects can be referred to each other.
