[0002] Rock wool board, also known as rock wool insulation decorative board, is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. When processing and producing rock wool boards, water is needed to cool and shape the rock wool boards. The water that absorbs heat is cooled by using a water circulation cooling tower and the water is recycled. Since the rock wool board will produce fine particles in the surrounding environment during processing, these dust and fine fibers in the surrounding environment will be brought into the cooling medium. When water cooling is carried out, it is easy to cause the water to be mixed with fine particles. When water is introduced into the cooling tower and sprayed out from the spray hole, long-term use will cause the spray hole to be blocked, resulting in uneven spraying. Uneven spraying will affect the heat exchange efficiency, resulting in uneven heat exchange in the tower and affecting the cooling effect. Summary of the Invention

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1: Reference Figure 1-5, a rock wool board production water circulation cooling tower, including a tower body 1, a packing layer 3 is fixedly connected inside the tower body 1, the packing layer 3 is made of polyvinyl chloride material, the lower end of the packing layer 3 is provided with a plurality of air inlet holes 4 opened on the tower body 1, the lower end of the tower body 1 is connected with a drain pipe 6, a cross 18 is fixedly connected inside the tower body 1, a spray part 5 is fixedly connected to the cross 18, a plurality of spray holes 17 are equidistantly provided on the spray part 5, the spray part 5 is connected with the water inlet pipe 2, and the water inlet pipe 2 is connected with a water pump, and the cooling water that absorbs heat is pumped into the cooling tower through the water pump. When the hot water passes through the packing layer 3 of the cooling tower, part of the moisture evaporates into water vapor, exchanges heat with the air, thereby reducing the water temperature, and the exhaust fan 7 generates airflow, and discharges the hot air from the top of the tower body into the atmosphere, promoting heat transfer, thereby cooling the hot water, and the cooled water is discharged from the drain pipe 6 to continue to cool the rock wool board and circulate the water.

[0026] The plurality of air inlet holes 4 are arranged tilted downward to prevent water from flowing out of the air inlet holes 4 .

[0027] An exhaust fan 7 is fixedly connected to the upper end of the tower body 1. The exhaust fan 7 is located above the spray part 5 and discharges hot air and water vapor out of the cooling tower.

[0028] The dredging rods 12 are arranged above the plurality of spray holes 17, and the plurality of dredging rods 12 all pass through the spray part 5. The plurality of dredging rods 12 are fixedly connected to a fixing frame 10, and the fixing frame 10 is fixedly connected to a threaded column 15. The threaded cylinder 16 is threadedly connected to the threaded column 15, and the threaded cylinder 16 is rotatably connected to the fixing plate 28 through a bearing. The fixing plate 28 is fixedly connected to the tower body 1, and the threaded cylinder 16 is driven by a fixed-axis rotating mechanism. Since water is sprayed from the spray holes 17 during use, when the spray holes 17 are blocked, affecting the uniformity of spraying, the fixed-axis rotating mechanism drives the threaded cylinder 16 to rotate, thereby adjusting the position of the threaded column 15 in the threaded cylinder 16, driving the plurality of dredging rods 12 to move, thereby dredging the blocked spray holes 17, ensuring the uniformity of spraying, thereby preventing the spray holes 17 from being blocked, causing uneven spraying to affect the heat exchange efficiency, resulting in uneven heat exchange in the tower, and affecting the cooling effect.

[0029] A rubber layer is provided on each of the plurality of dredging rods 12 . The rubber layer serves to abut against the dredging rods 12 and the spraying part 5 , thereby preventing water from flowing out of the gap between the spraying part 5 and the dredging rods 12 .

[0030] Example 2: In Example 1, when the spray hole 17 is to be unblocked, the threaded cylinder 16 is driven to rotate by a fixed-axis rotating mechanism. Generally, the fixed-axis rotating mechanism is driven by a motor. When driving, it needs to be started manually, and regular cleaning and unblocking cannot be performed. It is easy for blockage to occur and it takes a long time to unblock, thereby affecting the timeliness of spraying the spray hole 17.

[0031] Reference Figure 1-7 As another preferred embodiment of the present invention, on the basis of embodiment 1, the fixed-axis rotation mechanism includes a second gear 19, the second gear 19 is fixedly connected to the threaded cylinder 16, the second gear 19 is meshed with a rack 22, one end of the rack 22 is fixedly connected to a roller 21, and the other end is fixedly connected to a moving block 25, the moving block 25 is fixedly connected to a spring 24, the spring 24 is in a compressed state, the spring 24 is fixedly connected to a connecting ear, the connecting ear is fixedly connected to the fixed plate 28, the roller 21 abuts against a rotating disk 20, the rotating disk 20 is fixed The rotating disk 20 is provided with a groove 26, and both sides of the groove 26 are provided with inclined surfaces. The rotating disk 20 is connected with a rotating shaft 27, and the rotating shaft 27 is connected with the output shaft of the exhaust fan 7 through a meshing mechanism. When the exhaust fan 7 rotates, the incomplete gear 9 is driven to rotate. The rotation speed of the exhaust fan 7 is faster, resulting in a faster rotation speed of the incomplete gear 9. Only when the teeth of the incomplete gear 9 are meshed with the first gear 8 can the first gear 8 be driven to rotate, thereby playing a role in the first gear 8. The deceleration effect makes it take a long time for the first gear 8 to rotate one circle. When the roller 21 contacts the rotating disk 20, the spring 24 is in a compressed state. When the rotating disk 20 continues to rotate with the first gear 8, the groove 26 is aligned with the roller 21. Under the action of the restoring force of the spring 24, the roller 21 enters the groove 26, which will drive the rack 22 to move, thereby driving the second gear 19 to rotate, driving the threaded cylinder 16 to rotate, thereby driving the fixed frame 10 to move, and driving the multiple dredging rods 12 to move and dredge. When the rotating disk 20 continues to rotate, the first gear 8 is rotated, and the groove 26 is aligned with the roller 21. Under the action of the restoring force of the spring 24, the roller 21 enters the groove 26, which will drive the rack 22 to move, thereby driving the second gear 19 to rotate, driving the threaded cylinder 16 to rotate, thereby driving the fixed frame 10 to move, and driving the multiple dredging rods 12 to move and dredge. Rotation will cause the roller 21 to disengage from the groove 26, driving the roller 21 to reset, thereby resetting the rack 22 and continuing to compress the spring 24. When the rack 22 moves and resets, it will drive the threaded cylinder 16 to reverse, driving the fixing frame 10 to reset, thereby driving the dredging rod 12 to reset, so as to regularly dredge the spray hole 17, ensuring the timeliness of cleaning the spray hole 17. By controlling the number of teeth of the incomplete gear 9 and the first gear 8, the time required to rotate the first gear 8 one circle can be controlled, and the interval time for cleaning the spray hole 17 can be controlled.

[0032] The prism 23 is fixedly connected to the connecting ear, and a through slot is provided on the moving block 25. The prism 23 passes through the through slot. When the rack 22 moves, it will drive the moving block 25 to move on the prism 23. The prism 23 prevents the rack 22 from deviating so that the rack 22 can engage with the second gear 19.

[0033] The meshing mechanism includes an incomplete gear 9, which is fixedly connected to the output shaft of the exhaust fan 7. A first gear 8 is fixedly connected to the rotating shaft 27. The first gear 8 meshes with the incomplete gear 9. The number of teeth of the first gear 8 is greater than that of the incomplete gear 9. The incomplete gear 9 and the first gear 8 are used for transmission. Since the first gear 8 only drives the first gear 8 to rotate for a small part of the time when it rotates one circle, it is beneficial to reduce the load on the exhaust fan 7. Due to the high speed of the exhaust fan 7, when the incomplete gear 9 is disengaged from the first gear 8, the first gear 8 will continue to rotate due to the inertia of the first gear 8, causing the first gear 8 to offset when meshing with the incomplete gear 9, making it difficult to mesh with the first gear 8 and drive the first gear 8 to rotate. By using the restoring force of the spring 24, the roller 21 will abut against the rotating disk 20, increasing the resistance of the rotating disk 20 when it rotates, preventing the first gear 8 from rotating when the incomplete gear 9 is disengaged from the first gear 8, thereby ensuring the re-engagement of the incomplete gear 9 and the first gear 8.

[0034] When in use: the cooling water that absorbs heat is pumped into the cooling tower through the water pump and evenly sprayed through the spray part 5. When the hot water passes through the packing layer 3 of the cooling tower, part of the water evaporates into water vapor and exchanges heat with the air, thereby reducing the water temperature. The exhaust fan 7 generates airflow and discharges the hot air from the top of the tower into the atmosphere, promoting heat transfer, thereby cooling the hot water. The cooled water is discharged from the drain pipe 6. When the exhaust fan 7 rotates;

[0035] The incomplete gear 9 will be driven to rotate. Only when the teeth of the incomplete gear 9 mesh with the first gear 8 can the first gear 8 be driven to rotate. After the first gear 8 rotates for a period of time, the groove 26 on the rotating disk 20 is aligned with the roller 21. Under the action of the restoring force of the spring 24, the roller 21 enters the groove 26, which will drive the rack 22 to move, thereby driving the second gear 19 to rotate, driving the threaded cylinder 16 to rotate, adjusting the position of the threaded column 15 in the threaded cylinder 16, thereby driving the fixed frame 10 to move, driving the multiple dredging rods 12 to move, and dredging the spray holes 17. When the rotating disk 20 continues to rotate, the roller 21 will be disengaged from the groove 26, driving the roller 21 to reset, thereby resetting the rack 22, and continuing to compress the spring 24. When the rack 22 is reset, the threaded cylinder 16 will be driven to reverse, driving the fixed frame 10 to reset, thereby driving the dredging rod 12 to reset, and regularly dredging the spray holes 17.

[0036] Example 3: Reference Figure 1-5 As another preferred embodiment of the present invention, on the basis of Example 2, two connecting rods 13 are fixedly connected to the fixing frame 10, and the two connecting rods 13 both pass through the fixing plate 28. The upper ends of the two connecting rods 13 are fixedly connected with a stopper 14. During adjustment, when the threaded column 15 moves to the lowest position, the threaded connection distance between the threaded column 15 and the threaded barrel 16 will be shorter, which will easily cause the threaded connection to be damaged when supporting the fixing frame 10. By adopting the design of the stopper 14, when the threaded column 15 moves to the lowest end, the stopper 14 will abut against the fixing plate 28, thereby supporting the fixing frame 10 and preventing damage to the threaded connection.

[0037] The threaded column 15 and the threaded barrel 16 are made of stainless steel. Some other metal materials, such as the spring 24, can also be made of stainless steel.

[0038] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
