The existing centrifugal atomizing nozzles are mostly connected to the corresponding spray pipes by threads. When it is necessary to disassemble the centrifugal atomizing nozzles, special tools are required, which is a rather cumbersome operation. Utility Model Content

A sliding groove is provided through one end of the T-shaped insert at the locking block, and auxiliary protrusions are symmetrically installed on both sides of the other end of the T-shaped insert, with the auxiliary protrusions parallel to the sliding groove.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-6 A closed-loop cooling tower with centrifugal spraying includes a closed-loop cooling tower body 1, a centrifugal atomizing spraying unit 2, a branch spray pipe 21, a plurality of spray holes are equally spaced at the bottom of the branch spray pipe 21, and an atomizing nozzle assembly 3 is provided at the bottom of the branch spray pipe 21 at the spray holes. The atomizing nozzle assembly 3 includes a fixing ring seat 31, an atomizing nozzle body 32 is inserted into the bottom of the fixing ring seat 31, and L-shaped fixing blocks 321 are symmetrically installed at both ends of the atomizing nozzle body 32. A limiting member 322 is inserted into the L-shaped fixing block 321, and the atomizing nozzle body 32 and the fixing ring seat 31 are connected by the limiting member 322.

[0023] It is also worth noting that the end of the fixed ring seat 31 away from the inlet and outlet slide is fixedly connected to the branch spray pipe 21.

[0024] It is worth noting that the specific structure, connection method and working principle of the closed cooling tower body 1 and the centrifugal atomizing spray unit 2 are all existing technologies that are currently publicly available on the market, and are not the main technical problems to be solved in this utility model. Therefore, this utility model will not elaborate on them.

[0025] Meanwhile, a fixing ring is fitted on the top of the atomizing nozzle body 32, and a sealing ring 324 is fixedly installed on the top of the fixing ring. A limiting protrusion 323 is installed on the outer wall of the fixing ring at the corresponding L-shaped fixing block 321.

[0026] Meanwhile, the bottom end of the fixing ring seat 31 is provided with a locking groove on the side of the fixing ring and the atomizing nozzle body near the fixing ring, and the bottom end of the fixing ring seat 31 is provided with an inlet / outlet slide groove 311 at the limiting protrusion 323, and the fixing ring seat 31 is provided with a locking cavity 312 outside the locking groove and at the limiting protrusion 323.

[0027] Furthermore, cavities are symmetrically opened on both sides of the bottom of the cavity 312, and magnetic blocks 313 are fixedly installed in the cavity. The limiting protrusion 323 is made of a magnetic material that attracts the magnetic blocks 313. The magnetic blocks 313 and the inlet / outlet slide 311 are in an interleaved state. It is worth noting that the magnetic blocks 313 are strong magnetic.

[0028] Furthermore, the limiting member 322 includes a T-shaped insert, a cavity is provided at the T-shaped insert, and locking blocks are symmetrically installed at both ends of the cavity on the side away from the fixed ring seat 31. A sliding groove is provided through one end of the T-shaped insert at the locking block, and auxiliary protrusions are symmetrically installed on both sides of the other end of the T-shaped insert.

[0030] In this embodiment, after the limiting protrusion 323 of the atomizing nozzle body 32 is aligned with the inlet / outlet slide groove 311 of its fixing ring seat 31 and inserted, the atomizing nozzle body 32 is rotated so that its magnetic suction block 313 is magnetically attracted to the limiting protrusion 323, and its limiting member 322 is aligned with its slot. At the same time, the atomizing nozzle and the branch spray pipe 21 are initially connected and fixed. One end of the limiting member 322 is inserted into the fixing ring seat 31. Before insertion, it is ensured that the slide groove of the limiting member 322 is aligned with its slot. After the block is inserted, the limiting member 322 is rotated until the slide groove and the locking block are in an interlocked state. During the rotation of the limiting member 322, its auxiliary protrusion rotates in the corresponding movable cavity, further ensuring the stability of the connection between the atomizing nozzle and the branch spray pipe 21. At the same time, it makes the disassembly and assembly of the atomizing nozzle and the branch spray pipe 21 quick and convenient, and the entire disassembly and assembly process is tool-free. It also facilitates the quick disassembly and maintenance of the atomizing nozzle when the closed cooling tower is being maintained.

[0031] In this utility model, after the atomizing nozzle body 32 is inserted into and rotated with the fixing ring seat 31, its magnetic block 313 and the limiting protrusion 323 are magnetically attracted. With the setting of the limiting part 322, the atomizing nozzle and the branch spray pipe 21 can be quickly and conveniently disassembled and assembled. It is also convenient to quickly disassemble and maintain the atomizing nozzle when the closed cooling tower is being maintained.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
