Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically a novel closed-loop cooling tower. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. Its cooling mechanism utilizes the heat exchange between water and air to generate steam. The steam evaporates and carries away the heat, achieving heat dissipation through evaporation, convection, and radiation. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems, thereby lowering the water temperature and ensuring the normal operation of the system. The device is generally cylindrical, hence the name cooling tower.

[0003] Currently, to prevent dust from the environment from entering the cooling tower and to ensure proper airflow, existing technologies typically involve installing a ring-shaped filter structure at the bottom of the cooling tower shell to filter the air. While this initially provides noticeable results, the ring-shaped filter structure becomes increasingly clogged over time. If not addressed promptly, this can reduce the overall operating efficiency of the cooling tower. However, prolonged downtime for cleaning can disrupt the operation of other related equipment. Therefore, to address the aforementioned problems with existing technologies, the applicant proposes a novel closed-loop cooling tower solution. Utility Model Content

[0017] 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.

[0018] Please see Figure 1 and Figure 6A novel closed-loop cooling tower includes a cooling tower body 1 and an annular filter plate 2 fitted around the bottom of the cooling tower body 1. The front end of the annular filter plate 2 has a maintenance groove, and an adjusting plate 3 that can cover and seal the maintenance groove is slidably installed outside the maintenance groove. A first support ring plate 4, a second support ring plate 5, and a gear ring 6 are provided on the inner wall of the shell at the bottom of the cooling tower body 1. An extension sleeve 7 that communicates with its own space is installed at the front end of the shell at the bottom of the cooling tower body 1. The top of the first support ring plate 4 is fixed to the inner wall of the shell at the bottom of the cooling tower body 1. The second support ring plate 5 is fitted around the outside of the first support ring plate 4 through a bearing. The gear ring 6 is fitted around the top outside of the second support ring plate 5. A brush plate 16 is installed on one side of the bottom of the second support ring plate 5. A meshing assembly that can drive the gear ring 6 is fitted inside the extension sleeve 7. Under the meshing drive of the meshing assembly, the brush plate 16 can clean the annular filter plate 2 to prevent clogging. The brush plate 16 consists of a connecting rod and several brush strips arranged on one side of the connecting rod to ensure a thorough cleaning effect. One end of the connecting rod is fixed to the surface of the bottom side of the second support ring plate 5. The meshing assembly includes a first drive shaft 8 and a first gear 9. The middle part of the first drive shaft 8 is fitted onto the inner side of the middle part of the extension sleeve plate 7 through a bearing. The first gear 9 is fitted onto the middle surface of the first drive shaft 8 and meshes with the side of the gear ring 6. A square through hole is provided on the inner side of the middle part of the first drive shaft 8 to provide convenient assembly conditions for applying force with a wrench set later.

[0019] When in use, when the annular filter plate 2 is used for a certain period of time and slight surface blockage occurs, the existing square wrench is fitted into the square through hole and turned. This drives the first gear 9 to rotate synchronously through the first drive shaft 8. The rotated first gear 9 will synchronously mesh with the transmission gear ring 6, causing the gear ring 6 to drive the second support ring plate 5 and the brush plate 16 to rotate back and forth in the space near the outer ring structure at the bottom of the cooling tower body 1 with the support of the first support ring plate 4. Then, the brush plate 16 is used to clean and deblock the annular filter plate 2, ensuring the continuous and efficient operation of the cooling tower body 1.

[0020] Please see Figure 3 and Figure 6 One end of the first drive shaft 8 extends to the top outer side of the extension sleeve 7 and is fitted with a limiting component. The limiting component includes an external threaded sleeve 10, an internal threaded sleeve 11, and a limiting ring. The limiting ring and the internal threaded sleeve 11 are respectively fixedly fitted on the surface of one end of the first drive shaft 8 and movably fitted on the outside of one end of the first drive shaft 8. The bottom of the external threaded sleeve 10 is fixed to the top of the extension sleeve 7, and the internal threaded sleeve 11 can lock and limit the assembly formed by the first drive shaft 8 and the limiting ring by being threadedly connected to the external threaded sleeve 10.

[0021] When in use, considering the stability of the brush plate 16 and other structures inside the cooling tower body 1 when not in use, after the brush plate 16 and other structures are used up, the internal threaded sleeve 11 is screwed until the internal threaded sleeve 11 is threadedly connected to the external threaded sleeve 10 until its maximum spiral stroke. In this way, the assembly formed by the first drive shaft 8 and the limiting ring is locked and limited by the threaded connection with the external threaded sleeve 10, ensuring that the brush plate 16 and other structures have stable conditions for use inside the cooling tower body 1.

[0022] Please see Figure 2 and Figure 6 The inner walls of the top and bottom of the adjusting plate 3 are both fitted with slide rails 17, which are fixedly sleeved on the surface of the annular filter plate 2. The other end of the first drive shaft 8 extends to the bottom outer side of the extension sleeve 7 and is fitted with a linkage structure. The linkage structure can rotate and adjust the adjusting plate 3, providing a strong condition for further expansion of the use of the overall device. The linkage structure includes a support frame plate 13, the top of which is fixed to the bottom of the extension sleeve plate 7. A gear shaft 14 is mounted on the bottom of the support frame plate 13 via a bearing. An arc-shaped toothed plate 12 fixed on the surface of the adjusting plate 3 meshes with the outer side of the bottom of the gear shaft 14. A T-shaped screw 15 is threadedly connected to the bottom of the support frame plate 13. A positioning hole is provided at the bottom of the gear shaft 14, and the T-shaped screw 15 can be engaged and limited with the gear shaft 14 under the helical support of the support frame plate 13.

[0023] Working principle: During use, considering the stable opening and closing requirements of the adjustment plate 3 on the maintenance groove inside the annular filter plate 2, the adjustment plate 3 is assisted in adjustment using the gear shaft 14 and other structures supported by the extension sleeve 7, as follows: When the maintenance slot needs to be opened, pause the cooling tower body 1, turn the T-screw 15 until one end of the T-screw 15 is disengaged from the positioning hole, then push the adjusting plate 3 so that the adjusting plate 3 rotates and moves along the surface of the annular filter plate 2 under the guidance of the two slide rails 17, making room for the maintenance slot. After the maintenance tank is finished, reset the adjustment plate 3 to its initial position. During the reset process, the gear shaft 14 meshes with the arc-shaped toothed plate 12, which, together with the two slide rails 17, further enhances the connection strength between the adjustment plate 3 and the annular filter plate 2, and also further enhances the self-locking effect of the adjustment plate 3 relative to the annular filter plate 2. Then, reset and install the T-screw 15 so that one end of the T-screw 15 is re-engaged with the positioning hole.
