Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and specifically to a rotating structure for atomizing nozzles in cooling towers. Background Technology

[0002] A cooling tower is a device that uses the contact between water and air flow to exchange heat and cool water, thereby reducing the water temperature. The atomizing nozzles on the cooling tower atomize water into tiny droplets through high-pressure water flow and spray them evenly into the interior of the cooling tower. When the water droplets come into contact with the air, heat exchange occurs, thereby reducing the water temperature. At the same time, the water droplets collide with the packing material during their descent, further increasing the surface area of ​​the water droplets and improving the cooling efficiency.

[0003] However, the atomizing nozzles currently in use are fixed in position and cannot be rotated, which results in the water droplets sprayed from the nozzles spraying in a fixed direction, limiting the spray range and causing poor performance. Summary of the Invention

[0004] This invention addresses the problem of difficulty in rotating atomizing nozzles on cooling towers during use by providing a rotating structure for cooling tower atomizing nozzles. This structure enables the atomizing nozzles to rotate during use, thereby increasing the spray range and improving the performance.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A rotating structure for a cooling tower atomizing nozzle includes a first connecting pipe, a second connecting pipe, and a driving component. The first connecting pipe is connected to the second connecting pipe via a rotary joint, and the free end of the second connecting pipe is connected to the nozzle body. Both the first and second connecting pipes are fitted with a sleeve, and the top plate of the sleeve is fixedly connected to the first connecting pipe. The driving component includes a cover, a rotating rod, and a worm gear. The cover is hollow inside and open at the right end. The right end opening of the cover penetrates and is fixedly connected to the left end of the circumferential wall of the connecting pipe. The rear end of the rotating rod is rotatably connected to the rear part of the circumferential wall of the sleeve, and the front end is movably connected to the front part of the circumferential wall of the sleeve through the cover. The rotating rod inside the cover has a ring array of force plates. The free end of the force plate on the right side of the rotating rod extends into the first connecting pipe. The second connecting pipe is fitted with a worm gear. The lower side of the rotating rod is provided with a worm gear meshing with the worm gear. The front and rear ends of the worm gear are rotatably connected to the front and rear parts of the circumferential wall of the sleeve, respectively. The rotating rod and the worm gear are fitted with a belt.

[0007] Furthermore, the top plate of the sleeve is provided with a round hole in the middle, and the sleeve is fixedly connected to the connecting pipe 1 through the round hole on the top plate of the sleeve. The lower end of the sleeve is open, the upper end of the nozzle body slides in contact with the lower end of the sleeve, and multiple atomizing nozzles are evenly distributed at the bottom of the nozzle body.

[0008] Furthermore, the cover is a hollow structure consisting of an arc-shaped plate with a protrusion facing left, the front and rear ends of which are sealed by a sealing plate. The arc-shaped plate on the cover is a superior arc-shaped plate, and the rotating rod and the arc-shaped plate are coaxially arranged.

[0009] Furthermore, the length of the force-bearing plate is greater than the distance from the rotating rod to the left end of the connecting pipe's circumference; the diameter of the circle containing the free ends of the plurality of force-bearing plates is smaller than the inner diameter of the ring containing the arc-shaped plate on the cover.

[0010] Furthermore, the distance between the front and rear outer surfaces of the cover is less than the outer diameter of the connecting pipe; the distance between the front and rear ends of the peripheral wall of the connecting pipe and the front and rear ends of the cover are equal.

[0011] Furthermore, the belt includes belt one and belt two. On the outer side of the front of the cover, the rotating rod peripheral wall and the worm peripheral wall are provided with annular grooves one facing each other vertically. Belt one is fitted around the two annular grooves one. On the outer side of the rear of the cover, the rotating rod peripheral wall and the worm peripheral wall are provided with annular grooves two facing each other vertically. Belt two is fitted around the two annular grooves two.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] In this invention, after the spray water enters the connecting pipe 2 through the connecting pipe 1, it is then sprayed out through the nozzle body. When the spray water passes through the connecting pipe 1, the impact plate drives the rotating rod to rotate. Through the transmission of belt 1 and belt 2, the worm rotates with the rotating rod. The worm meshes with the worm wheel to drive the connecting pipe 2 to rotate, which in turn drives the nozzle body to rotate. At the same time as the spray water is sprayed out through the atomizing nozzle on the nozzle body, it also generates rotational motion, thereby making the spray water cover a larger range and improving the use effect.

The free end of the connecting pipe 2 is connected to the nozzle body 4. A sleeve 5 is fitted over both connecting pipes 1 and 2. The top plate of the sleeve 5 is fixedly connected to the connecting pipe 1. The sleeve 5 is a cylindrical body with an inner diameter larger than the outer diameter of the connecting pipe 1 and a closed upper end. The driving component includes a cover 6, a rotating rod 7, and a worm gear 11. The cover 6 is hollow inside and open at the right end. The right end of body 6 is open and fixedly connected to the left end of the circumferential wall of connecting pipe 1. The rotating rod 7 is a round rod. The rear end of the rotating rod 7 is rotatably connected to the rear part of the circumferential wall of sleeve 5, and the front end is movably connected to the front part of the circumferential wall of sleeve 5 through body 6. There are force plates 8 arranged in a ring on the rotating rod 7 inside body 6. The force plates 8 are rectangular plates. The free end of the force plate 8 on the right side of the rotating rod 7 extends into connecting pipe 1. The connecting pipe 2 is fitted with a worm gear 9. The rotating rod 7 is provided with a worm 11 that meshes with the worm gear 9 on the lower side. The front and rear ends of the worm 11 are rotatably connected to the front and rear parts of the circumferential wall of sleeve 5, respectively. The rotating rod 7 and the worm 11 are both fitted with a belt.

[0022] The top plate of the sleeve 5 has a round hole 13 in the middle. The sleeve 5 is fixedly connected to the connecting pipe 1 through the round hole 13 on the top plate of the sleeve 5. The lower end of the sleeve 5 is open. The upper end of the nozzle body 4 slides in contact with the lower end of the sleeve 5. Multiple atomizing nozzles 14 are evenly distributed at the bottom of the nozzle body 4. The nozzle body 4 selected in this utility model is the nozzle body in the authorized publication number CN220405992 U "A Rotary Mechanism for Atomization of Cooling Tower".

[0023] The cover 6 is a hollow structure consisting of an arc-shaped plate 61 with a protrusion facing left, the front and rear ends of which are sealed by a sealing plate 62. The arc-shaped plate 61 on the cover 6 is an arc-shaped plate, and the rotating rod 7 and the arc-shaped plate 61 are coaxially arranged.

[0024] The length of the force-bearing plate 8 is greater than the distance from the rotating rod 7 to the left end of the connecting pipe 1; the diameter of the circle containing the free ends of the plurality of force-bearing plates 8 is smaller than the inner diameter of the ring containing the arc plate 61 on the cover 6.

[0025] The distance between the front and rear outer surfaces of the cover 6 is less than the outer diameter of the connecting pipe 1; the distance between the front and rear ends of the peripheral wall of the connecting pipe 1 and the front and rear ends of the cover 6 are equal.

[0026] The belt includes belt one 15 and belt two 16. On the outer side of the front of the cover 6, the rotating rod 7 and the worm gear 11 are provided with annular grooves one 17 facing each other vertically.

On the outer side of the rear of the cover 6, the rotating rod 7 and the worm gear 11 are provided with annular grooves two 18 facing each other vertically. Belt two 16 is fitted around the two annular grooves two 18.

[0027] This utility model is installed inside a cooling tower. The free end of the connecting pipe 1 is connected to a water supply pipe. In use, the water supply pipe supplies spray water into the connecting pipe 1 from top to bottom. The spray water enters the connecting pipe 2 through the rotary joint 3, and then enters the nozzle body 4 and is sprayed out through the atomizing nozzle 14. As the spray water flows downwards through the connecting pipe 1, it impacts the force-bearing plates 8 extending into the connecting pipe 1. The impact on the multiple force-bearing plates 8 causes the rotating rod 7 to rotate clockwise (the clockwise rotation of the rotating rod 7 is...). Figure 2 From the perspective of the rotating rod 7, when the rotating rod 7 rotates, the worm gear 11 is driven to rotate synchronously with the rotating rod 7 via belt 15 and belt 2 16. When the worm gear 11 rotates, it meshes with the worm wheel 9 to make the connecting pipe 2 rotate, and the nozzle body 4 rotates with the connecting pipe 2. Therefore, while the spray water is sprayed out through the atomizing nozzle 14 on the nozzle body 4, it will also generate a rotational motion, thereby making the spray water spray a larger range and improving the use effect.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
