A cooling tower embedded packing bracket

Abstract

This utility model belongs to the technical field of cooling equipment structure and discloses a cooling tower embedded packing bracket, including a cooling tower shell, an installation column connected to the center of the bottom of the inner wall of the cooling tower shell, and a servo motor connected to the bottom of the cooling tower shell. A rotating shaft is rotatably connected to the inner wall of the installation column. Compared with the existing fixed bracket structure, this solution introduces a servo motor drive mechanism into the packing bracket structure to realize the bracket's reciprocating rotation within a certain angle range at the outer end of the installation column. This causes the packing to generate inertial vibration during operation, thereby effectively shaking off impurities, reducing scaling, and preventing blockage. At the same time, it forms dynamic turbulence, improving heat exchange efficiency. Combined with the limiting structure and the double-sided buffer spring mechanism, it not only ensures precise and controllable rotation but also significantly reduces the impact force generated when the motor starts, stops, or reverses, effectively protecting the bracket and its connecting parts from mechanical damage. The overall structure is more stable and has a longer service life.

Description

Technical Field

[0001] This utility model relates to the field of cooling equipment structure technology, and in particular to a cooling tower embedded packing bracket. Background Technology

[0002] A cooling tower is a heat exchange device commonly used in industrial circulating water systems. It mainly achieves the purpose of lowering water temperature through heat exchange between water and air. Inside the cooling tower, the packing is the core component of heat exchange, used to expand the contact area between water and air and improve cooling efficiency. To ensure the stability and structural integrity of the packing, a packing support is usually installed inside the tower body to support, fix and fix the packing layer, and maintain its relative position in the tower body.

[0003] In existing technologies, packing supports are generally fixed structures, usually made of metal or engineering plastic materials, and are erected on the cooling tower shell or internal skeleton in the form of mesh, ribs or frames. Although these fixed supports have a certain load-bearing capacity, during long-term operation, impurities, algae and scale contained in the cooling water are prone to accumulate on the surface of the packing, leading to packing blockage, obstructed ventilation, and further reduction in heat exchange efficiency. Especially in high hardness water quality or dusty environments, the problem of packing scaling is particularly prominent, making cleaning difficult and maintenance frequent, which seriously affects the operational stability and energy-saving effect of the cooling tower. Utility Model Content

[0004] This utility model aims to provide an embedded packing bracket for cooling towers to solve the problems mentioned in the background art. Compared with the existing fixed bracket structure, this solution introduces a servo motor drive mechanism into the packing bracket structure to realize the bracket's reciprocating rotation within a certain angle range at the outer end of the mounting column. This causes the packing to generate inertial vibration during operation, thereby effectively shaking off impurities, reducing scaling, and preventing blockage. At the same time, it forms dynamic turbulence, improving heat exchange efficiency. Combined with the limiting structure and the double-sided buffer spring mechanism, it not only ensures precise and controllable rotation but also significantly reduces the impact force generated when the motor starts, stops, or reverses, effectively protecting the bracket and its connecting parts from mechanical damage. The overall structure is more stable and has a longer service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cooling tower embedded packing bracket includes a cooling tower shell. A mounting column is connected to the center of the bottom of the inner wall of the cooling tower shell, and a servo motor is connected to the bottom of the cooling tower shell. A rotating shaft is rotatably connected to the inner wall of the mounting column. The rotating shaft is coaxially arranged with the inner cavity of the mounting column, and a rotating block is connected to the outer end of the rotating shaft. A mounting ring is rotatably connected to the outer end of the mounting column. A bracket is connected to the outer end of the mounting ring, and a driving block is connected to the inner wall of the mounting ring. A limiting hole is opened at the outer end of the mounting column. The driving block passes through the limiting hole and extends into the inner cavity of the mounting column. A driving groove matching the driving block is opened on the rotating block, and the driving block is located in the inner cavity of the limiting hole.

[0007] Preferably, the outer end of the mounting column is connected to an annular slide rail, the annular slide rail is disposed on the lower side of the bracket, and the bottom end of the bracket is connected to a baffle, the baffle being located on one side of the annular slide rail.

[0008] Preferably, the outer end of the annular slide rail is connected to a pair of oppositely arranged bases, and the baffle is located in the middle of the pair of bases.

[0009] Preferably, a pair of movable blocks are slidably connected on the annular slide rail, the pair of movable blocks are respectively located on both sides of the baffle, and a spring connects the movable blocks and the base.

[0010] Preferably, the outer ends of both the baffle and the movable block are covered with rubber pads.

[0011] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0012] Compared to existing fixed bracket structures, this solution introduces a servo motor drive mechanism into the packing bracket structure, enabling the bracket to reciprocate within a certain angle range at the outer end of the mounting column. This causes inertial vibration in the packing during operation, effectively shaking off impurities, reducing scaling, and preventing blockage. Simultaneously, it creates dynamic turbulence, improving heat exchange efficiency. Combined with a limiting structure and a double-sided buffer spring mechanism, it not only ensures precise and controllable rotation but also significantly reduces the impact force generated when the motor starts, stops, or reverses, effectively protecting the bracket and its connecting components from mechanical damage. The overall structure is more stable and has a longer service life. Attached Figure Description

[0019] A cooling tower is a heat exchange device commonly used in industrial circulating water systems. It mainly achieves the purpose of lowering water temperature through heat exchange between water and air. Inside the cooling tower, the packing is the core component of heat exchange, used to expand the contact area between water and air and improve cooling efficiency. To ensure the stability and structural integrity of the packing, a packing support is usually installed inside the tower body to support, fix and fix the packing layer, and maintain its relative position in the tower body.

[0020] In existing technologies, packing supports are generally fixed structures, usually made of metal or engineering plastic materials, and are erected on the cooling tower shell or internal skeleton in the form of mesh, ribs or frames. Although these fixed supports have a certain load-bearing capacity, during long-term operation, impurities, algae and scale contained in the cooling water are prone to accumulate on the surface of the packing, leading to packing blockage, obstructed ventilation, and further reduction in heat exchange efficiency. Especially in high hardness water quality or dusty environments, the problem of packing scaling is particularly prominent, making cleaning difficult and maintenance frequent, which seriously affects the operational stability and energy-saving effect of the cooling tower.

[0021] Therefore, this utility model provides a cooling tower packing support structure with active disturbance capability, which can improve the heat exchange conditions of the packing and reduce the risk of scaling and blockage, so as to further improve the operating efficiency and system stability of the cooling tower.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0023] like Figure 1-3The cooling tower embedded packing bracket shown includes a cooling tower shell 1. A mounting column 2 is connected to the center of the bottom of the inner wall of the cooling tower shell 1, and a servo motor 3 is connected to the bottom of the cooling tower shell 1. A rotating shaft 8 is rotatably connected to the inner wall of the mounting column 2. The rotating shaft 8 is coaxially arranged with the inner cavity of the mounting column 2, and a rotating block 9 is connected to the outer end of the rotating shaft 8. A mounting ring 5 is rotatably connected to the outer end of the mounting column 2. A bracket 4 is connected to the outer end of the mounting ring 5, and a driving block 6 is connected to the inner wall of the mounting ring 5. A limiting hole 11 is opened at the outer end of the mounting column 2. The driving block 6 passes through the limiting hole 11 and extends into the inner cavity of the mounting column 2. A driving groove 10 matching the driving block 6 is opened on the rotating block 9. The driving block 6 is located in the inner cavity of the limiting hole 11.

[0024] In this embodiment, the packing is placed at the top of the bracket 4, surrounding the mounting column 2, and filling the inner cavity of the cooling tower shell 1 in the horizontal direction. During the operation of the cooling tower, the user can start the servo motor 3 to drive the rotating shaft 8 to rotate, which in turn drives the rotating block 9 to rotate, which in turn drives the drive block 6 to move. This forces the mounting ring 5 and the bracket 4 to rotate at the outer end of the mounting column 2, thereby moving the packing. The servo motor 3 rotates in a reciprocating manner at a certain angle, ensuring that the range of motion of the drive block 6 is limited within the limiting hole 11. Through this reciprocating rotation, the packing generates inertial vibration during each rotation, thereby effectively shaking off attached impurities and preventing scale deposition. It also continuously disturbs the airflow and water flow path during operation, achieving the purpose of preventing the packing from scaling and clogging and improving cooling efficiency.

[0025] like Figure 3-5 As shown, the outer end of the mounting column 2 is connected to an annular slide rail 12, which is located on the lower side of the bracket 4. The bottom end of the bracket 4 is connected to a baffle 7, which is located on one side of the annular slide rail 12. The outer end of the annular slide rail 12 is connected to a pair of oppositely arranged bases 13, with the baffle 7 located in the middle of the pair of bases 13. A pair of movable blocks 15 are slidably connected on the annular slide rail 12, with the pair of movable blocks 15 located on both sides of the baffle 7. A spring 14 is connected between the movable blocks 15 and the bases 13. The outer ends of both the baffle 7 and the movable blocks 15 are covered with rubber pads.

[0026] In this embodiment, the bracket 4 rotates and drives the baffle 7 to move. When the baffle 7 moves to either side, it will contact the corresponding movable block 15 and push the movable block 15 to slide on the annular slide rail 12, thereby compressing the spring 14. The spring 14 can buffer the rotating bracket 4 and the mounting ring 5 to absorb the impact force generated by the motor during start-up, stop or reversal, thereby effectively reducing the damage of mechanical impact to the mounting ring 5 and various connecting structures, improving the stability and service life of the overall structure. The rubber pad is set to reduce the impact force generated between the baffle 7 and the movable block 15 each time, and to prevent its surface from wearing out too quickly.

[0027] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
