Description

Technical Field

[0001] This utility model relates to the field of air preheater technology, specifically to an installation structure for sealing an air preheater. Background Technology

[0002] The installation structure for air preheater sealing belongs to the field of air preheater sealing technology. It mainly involves the installation and adjustment of air preheater sealing devices, aiming to achieve effective sealing of air preheaters through a specific structure.

[0003] In existing technologies, the sealing installation structure of air preheaters often suffers from operational inconvenience. Some structures require complex operating procedures to achieve the sealing block's fit, increasing the difficulty of the sealing operation. Furthermore, some structures lack effective limiting designs for adjusting components. After the sealing block is fitted to the air preheater, the turntable can easily rotate unexpectedly, causing the sealing block to detach from the fitted state, making it difficult to maintain the stability of the sealing effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an installation structure for sealing air preheaters. This solves the problem that some of the aforementioned structures require complex operating steps to complete the sealing block bonding, increasing the difficulty of the sealing operation. At the same time, some structures lack effective limiting designs for adjustment components. After the sealing block is bonded to the air preheater, the turntable is prone to accidental rotation, causing the sealing block to detach from the bonded state, making it difficult to maintain the stability of the sealing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an installation structure for sealing an air preheater, comprising: an assembly plate and a hollow plate, wherein the hollow plate is disposed in the inner cavity of the assembly plate, and the assembly plate can be sleeved on the outside of the air preheater during use to provide a stable installation base for subsequent sealing operations; a sealing mechanism is provided on the outside of the assembly plate, wherein the sealing mechanism includes a turntable.

[0006] The turntable is uniformly connected to a connecting rod inside, and a push plate is rotatably connected to the other end of the connecting rod. A sealing block is connected to the outside of the push plate. The outside of the push plate is slidably connected to the inner cavity of the hollow disc. When the turntable is rotated, the push plate can be driven to slide in a straight line in the inner cavity of the hollow disc through the transmission action of the connecting rod, thereby synchronously driving the sealing block to move towards the air preheater, and finally making the sealing block tightly fit against the outer wall of the air preheater to achieve the sealing function.

[0007] The turntable has locking arms inserted on both sides of its exterior, and the assembly plate has slots on its exterior that fit the locking arms. Pulling the locking arms disengages them from the slots, releasing the rotation constraint on the turntable. After the sealing block is in contact with the air preheater, the locking arms are returned to their original position and inserted into the slots. The locking action between the locking arms and the slots restricts the position of the turntable, preventing accidental rotation of the turntable from causing the sealing block to detach from its contact state. An elastic element is provided between the locking arms and the turntable. This elastic element provides elastic restoring force during the retraction of the locking arms, ensuring that the locking arms can be stably inserted into the slots and improving the reliability of the locking structure.

[0008] Preferably, the inner cavity of the assembly plate is provided with a sealing sleeve, and the inner cavity of the sealing sleeve is embedded with a rubber gasket. The sealing sleeve can initially fit against the outside of the air preheater. With the elastic deformation characteristics of the rubber gasket, it can fill the tiny gap between the assembly plate and the air preheater, further enhancing the overall sealing performance and reducing airflow leakage.

[0009] Preferably, the upper end of the assembly tray is provided with a reinforcing surface, which can improve the structural strength of the upper end of the assembly tray and prevent the assembly tray from deforming due to external forces during installation, disassembly or long-term use. The outer surface of the assembly tray is provided with anti-slip texture, which can increase the friction between the operator's hand and the assembly tray, making it easier for the operator to hold the assembly tray stably for fitting, adjustment and other operations, and reducing the probability of operation errors.

[0010] Preferably, the turntable is uniformly provided with horizontal arms on its outer side, and the horizontal arms are connected to levers. The operator can rotate the horizontal arms synchronously by holding the levers and applying force, thereby driving the turntable to rotate more effortlessly and reducing the labor intensity and difficulty of the turntable rotation operation.

[0011] Preferably, the inner cavity of the hollow disc is slidably connected to a track block via a track groove, and the outside of the track block is connected to the push plate. The sliding cooperation between the track groove and the track block can accurately guide and limit the movement direction of the push plate, ensuring that the push plate always slides along the preset trajectory under the drive of the connecting rod, and avoiding the push plate from deviating, which would cause the sealing block to fail to accurately fit the air preheater.

[0012] Preferably, the inner cavity of the turntable is provided with a bearing, which is located outside the assembly plate. The bearing can effectively reduce the rotational friction between the turntable and the assembly plate, making the rotation operation of the turntable smoother, while reducing wear between the two and extending the service life of the structure. The outer surface of the assembly plate is uniformly provided with square grooves, which are slidably connected to the connecting rod. The square grooves can limit the range of motion of the connecting rod, preventing the connecting rod from deviating or shaking when rotating with the turntable, ensuring that the connecting rod can stably transmit power and ensuring the movement stability of the push plate and the sealing block.

[0013] Compared with the prior art, the present invention provides an installation structure for sealing an air preheater, which has the following advantages:

[0014] This air preheater sealing installation structure allows for convenient and effective sealing by rotating the turntable. A push plate slides linearly within the hollow disc's cavity via a connecting rod drive, simultaneously propelling the sealing block towards the air preheater and ensuring a tight seal against its outer wall. This eliminates the need for complex operating procedures, reducing the difficulty of the sealing operation. The engagement of the locking arms on both sides of the turntable with the slots on the assembly plate restricts the turntable's position after the sealing block is in contact with the air preheater. This prevents the sealing block from detaching due to accidental rotation of the turntable, maintaining the stability of the seal. Furthermore, the elastic element between the locking arms and the turntable provides a restoring force when the locking arms return to their original position, ensuring stable insertion into the slots and reducing the risk of loosening or failure of the locking structure. This further enhances the reliability of the overall sealing installation structure and guarantees the continuous stability of the air preheater's sealing state. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a technical solution; please refer to [link / reference]. Figure 1 and Figure 2An installation structure for sealing an air preheater includes: an assembly plate 1 and a hollow plate 2. The hollow plate 2 is disposed in the inner cavity of the assembly plate 1. When in use, the assembly plate 1 can be sleeved on the outside of the air preheater to provide a stable installation base for subsequent sealing operations. A sealing mechanism 3 is provided on the outside of the assembly plate 1. The sealing mechanism 3 includes a turntable 31.

[0022] The turntable 31 is uniformly connected to a connecting rod 33, and the other end of the connecting rod 33 is rotatably connected to a push plate 34. The outside of the push plate 34 is connected to a sealing block 35. The outside of the push plate 34 is slidably connected to the inner cavity of the hollow disk 2. When the turntable 31 is rotated, the push plate 34 can be driven to slide in a straight line in the inner cavity of the hollow disk 2 through the transmission action of the connecting rod 33, thereby synchronously driving the sealing block 35 to move towards the air preheater, and finally making the sealing block 35 tightly fit with the outer wall of the air preheater to achieve the sealing function.

[0023] Please see Figure 3 and Figure 4 The turntable 31 has locking arms 4 inserted on both sides of its exterior. The assembly plate 1 has a slot on its exterior that matches the locking arms 4. Pulling the locking arms 4 can disengage them from the slots, releasing the rotation constraint on the turntable 31. After the sealing block 35 is in contact with the air preheater, the locking arms 4 are returned to their original position and inserted into the slots. The locking action of the locking arms 4 and the slots restricts the position of the turntable 31, preventing the turntable 31 from rotating accidentally and causing the sealing block 35 to disengage. An elastic element 41 is provided between the locking arms 4 and the turntable 31. The elastic element 41 can provide elastic restoring force during the return of the locking arms 4, ensuring that the locking arms 4 can be stably inserted into the slots and improving the reliability of the locking structure.

[0024] The inner cavity of the assembly plate 1 is provided with a sealing sleeve 11, and the inner cavity of the sealing sleeve 11 is embedded with a rubber gasket. The sealing sleeve 11 can initially fit with the outside of the air preheater. With the elastic deformation characteristics of the rubber gasket, it can fill the tiny gap between the assembly plate 1 and the air preheater, further enhancing the overall sealing performance and reducing airflow leakage.

[0025] The upper end of the assembly tray 1 is provided with a reinforcing surface, which can improve the structural strength of the upper end of the assembly tray 1 and prevent the assembly tray 1 from deforming due to external forces during installation, disassembly or long-term use. The outside of the assembly tray 1 is provided with anti-slip texture, which can increase the friction between the operator's hand and the assembly tray 1, making it easier for the operator to hold the assembly tray 1 stably for fitting, adjustment and other operations, and reducing the probability of operation errors.

[0026] The turntable 31 is evenly provided with horizontal arms 36, and the horizontal arms 36 are connected to levers 37. The operator can hold the levers 37 and apply force to drive the horizontal arms 36 to rotate synchronously, thereby driving the turntable 31 to rotate more effortlessly and reducing the labor intensity and difficulty of rotating the turntable 31.

[0027] The inner cavity of the hollow disc 2 is slidably connected to a track block through a track groove. The outside of the track block is connected to the push plate 34. The sliding cooperation between the track groove and the track block can accurately guide and limit the movement direction of the push plate 34, ensuring that the push plate 34 always slides along the preset trajectory under the drive of the connecting rod 33, and avoiding the push plate 34 from deviating, which would cause the sealing block 35 to fail to accurately fit the air preheater.

[0028] The inner cavity of the turntable 31 is provided with a bearing 32, which is located on the outside of the assembly plate 1. The bearing 32 can effectively reduce the rotational friction between the turntable 31 and the assembly plate 1, making the rotation operation of the turntable 31 smoother, while reducing wear between the two and extending the service life of the structure. The outer surface of the assembly plate 1 is uniformly provided with square grooves, which are slidably connected to the connecting rod 33. The square grooves can limit the range of motion of the connecting rod 33, preventing the connecting rod 33 from deviating or shaking when it rotates with the turntable 31, ensuring that the connecting rod 33 can stably transmit power and ensuring the movement stability of the push plate 34 and the sealing block 35.

[0029] When using this solution, the assembly plate 1 is placed on the outside of the air preheater, the clamping arm 4 is pulled out of the clamping slot, and then the turntable 31 is rotated. The push plate 34 is driven to move through the connecting rod 33, which in turn drives the sealing block 35 to fit with the air preheater. Finally, the clamping arm 4 is returned to its original position and inserted into the inside of the clamping slot to restrict the position of the turntable 31.
