Description

Technical Field

[0001] This utility model relates to the field of cooling tower antifreeze technology, specifically an antifreeze structure for a cooling tower used in chemical hot water cooling treatment. Background Technology

[0002] As a water-circulating cooling system, a cooling tower can be considered a large radiator. It is responsible for introducing hot water from the chemical process into the heat dissipation coils, and then cooling the heat dissipation coils through air cooling or water cooling, so that the heat inside the heat dissipation coils can be transferred to the air, thereby achieving heat transfer and keeping the operating temperature of the equipment within a reasonable range.

[0003] Existing technologies typically involve wrapping the delivery pipes on the cooling tower with an insulating sleeve to protect them from freezing. However, the space at the bottom of the cooling tower is very enclosed, making it inconvenient for workers to wrap the delivery pipes at the bottom of the cooling tower with an insulating sleeve, thus reducing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an antifreeze structure for a cooling tower used in chemical hot water cooling treatment, so as to solve the technical problems of inadequate antifreeze wrapping and low efficiency in the existing system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an antifreeze structure for a cooling tower used for chemical hot water cooling treatment, comprising a cooling tower, a heat insulation sleeve, an mounting plate, and a connecting plate. A conveying pipe is fixedly connected to the bottom of the cooling tower. Multiple mounting grooves are provided at the top of the mounting plate. Rotating rods are rotatably connected inside each mounting groove. Connecting blocks are fixedly connected to each rotating rod. Limiting rings are fixedly connected to each connecting block. Torsion springs are fixedly connected to each connecting block at the position corresponding to the rotating rod. Limiting rods are fixedly connected to the bottom of the mounting plate. Limiting grooves are provided at the top of the connecting plate. Symmetrically arranged extrusion plates are fixedly connected to the connecting plate. Extrusion grooves are provided at one end of each extrusion plate.

[0006] As a preferred embodiment of this utility model, the insulation sleeve is movably fitted onto the surface of the conveying pipe.

[0007] In a preferred embodiment of this utility model, the connecting blocks are all located inside the mounting groove.

[0008] As a preferred embodiment of this utility model, one end of the rotating rod passes through the hollow position of the torsion spring, and one end of the torsion spring is fixedly connected to the inner wall of the corresponding mounting groove.

[0009] As a preferred embodiment of this utility model, the limiting rod is T-shaped and the limiting groove is T-shaped, with one end of the limiting rod slidably connected inside the limiting groove.

[0010] Compared with the prior art, the beneficial effect of the antifreeze structure of the cooling tower for chemical hot water cooling treatment of this utility model is that the cooperation of various components can reduce the difficulty of wrapping the bottom delivery pipe of the cooling tower. There is no need for workers to crawl into the bottom of the cooling tower. They can wrap the delivery pipe with the insulation sleeve while standing next to the cooling tower, which improves the wrapping efficiency of the insulation sleeve and reduces the operation difficulty of workers.

[0020] See Figure 1-4 As shown in the figure, an antifreeze structure for a cooling tower for chemical hot water cooling treatment according to an embodiment of the present invention includes a cooling tower 1, a heat insulation sleeve 2, a mounting plate 3 and a connecting plate 4. A conveying pipe 5 is fixedly connected to the bottom end of the cooling tower 1. Multiple mounting grooves 6 are opened at the top end of the mounting plate 3. A rotating rod 7 is rotatably connected inside each mounting groove 6. A connecting block 8 is fixedly connected to each rotating rod 7. A limit ring 9 is fixedly connected to each connecting block 8. A torsion spring 10 is fixedly connected to each connecting block 8 at the position corresponding to the rotating rod 7.

[0021] The bottom end of the mounting plate 3 is fixedly connected to a limit rod 11, the top end of the connecting plate 4 is provided with a limit groove 12, and the connecting plate 4 is fixedly connected with symmetrically arranged extrusion plates 13, each of which has an extrusion groove 14 at one end.

[0022] The insulation sleeve 2 is movably fitted on the surface of the conveying pipe 5. The insulation sleeve 2 can provide antifreeze function for the conveying pipe 5. The connecting blocks 8 are all located inside the mounting groove 6. The mounting groove 6 is the space where the connecting blocks 8 can rotate. One end of the rotating rod 7 passes through the hollow position of the torsion spring 10. One end of the torsion spring 10 is fixedly connected to the corresponding inner wall of the mounting groove 6. The fixed connection between the torsion spring 10 and the inner wall of the mounting groove 6 facilitates the reset of the rotating connecting block 8. The limiting rod 11 is T-shaped. The limiting groove 12 is T-shaped. One end of the limiting rod 11 is slidably connected inside the limiting groove 12. The connection between the limiting groove 12 and the limiting rod 11 facilitates the movement guidance of the connecting plate 4.

[0023] When using this embodiment of the invention, the insulation sleeve 2 is fitted onto the conveying pipe 5, and the mounting plate 3 is placed directly below the conveying pipe 5, so that the conveying pipe 5 is located in the middle position of each limiting ring 9, as shown below. Figure 3Connect the limiting groove 12 on the connecting plate 4 to the limiting rod 11, push the connecting plate 4 towards the cooling tower 1, and the moving connecting plate 4 will drive the extrusion plate 13 to move together. When the extrusion plate 13 moves, the extrusion groove 14 on the extrusion plate 13 will extrude the corners of the limiting ring 9, so that each limiting ring 9 will rotate in the middle direction at the same time. The rotating limiting ring 9 will cause the connecting block 8 to drive the rotating rod 7 to rotate together. The rotation of the connecting block 8 will also cause the torsion spring 10 to rotate and twist. Then, move the connecting plate 4 completely to the bottom of the mounting plate 3 to complete the closure of multiple limiting rings 9. After the limiting rings 9 are closed, they will clamp and fix the insulation sleeve 2 on the conveying pipe 5. When disassembling, simply remove the connecting plate 4, and the torsion spring 10 will drive the rotating rod 7, the connecting block 8 and the limiting ring 9 back to their original positions to complete the disassembly.
