Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomizing nozzle technology, specifically to a detachable and washable atomizing nozzle assembly. Background Technology
[0002] As a key device for converting liquids into fine droplets, the core function of atomizing nozzles is to apply shearing, impact, or rotational forces to the fluid through a precise internal structure, thereby enabling the liquid to overcome surface tension and achieve microparticle atomization. In the paper processing field, such components are widely used in paper surface coating, sizing, humidification, and functional liquid spraying processes, and have a significant impact on the uniformity and surface properties of the finished paper. Existing atomizing nozzles used in paper processing generally suffer from several inherent problems during long-term continuous operation. Pulp fibers, coating components, or other additives tend to accumulate gradually inside the nozzle, especially under conditions of high solids content or viscous slurries. Scaling and clogging easily occur in the swirl channel and spray orifice, leading to decreased atomization and even spraying interruption. Most nozzles use an integrated or partially detachable structure, making thorough cleaning of the flow channel difficult. Maintenance requires machine shutdown and disassembly, affecting production continuity. Furthermore, common sealing designs are prone to loss of sealing performance due to wear after repeated disassembly and reassembly, causing liquid leakage. This not only affects process efficiency but may also contaminate equipment. In addition, the lack of an effective online anti-clogging mechanism makes the filter device susceptible to clogging by fibrous impurities, increasing flow resistance and reducing nozzle lifespan, thus leading to increased maintenance costs and decreased production efficiency. Therefore, we propose a detachable and washable atomizing nozzle assembly. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a detachable and washable atomizing nozzle assembly that can achieve quick disassembly and cleaning maintenance, long-term sealing and dynamic anti-clogging function, and can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a detachable and washable atomizing nozzle assembly, including a connecting pipe and a spraying assembly; Connecting pipe: The left end is fixed with an external threaded pipe, and the right end of the surface of the connecting pipe is threaded with a connecting cover. The inside of the connecting cover is a flow guiding component, and the right end of the inside of the connecting pipe is a sealing component. The left end of the flow guiding component is connected to the sealing component, and the inside of the sealing component is a filter component. The left end of the flow guiding component is a squeezing component, and the squeezing component is in contact with the filter component. The spray assembly includes a connecting plate, a spray nozzle, a conical groove, and a spiral guide groove. The right end of the connecting cover has an opening, and the connecting plate is fixed inside the opening. The middle of the connecting plate has a spray nozzle, and the left end of the connecting plate has a conical groove and a uniformly distributed spiral guide groove. By setting the spray assembly, when in use, the liquid flowing out of the uniformly distributed liquid outlet will be sprayed out sequentially through the spiral guide groove, the conical groove, and the spray nozzle, thus effectively atomizing the liquid.
[0005] Furthermore, the flow guiding assembly includes a fixing frame, a blocking plate, a connecting ring, a liquid outlet, and a conical ring. Three corresponding fixing frames are fixed inside the connecting cover, and a blocking plate is fixed between the three fixing frames. A connecting ring is fixed to the left end of the blocking plate. The connecting ring has evenly distributed liquid outlets on its circumferential surface. A conical ring is fixed to the left end of the connecting ring. The flow guiding assembly guides the liquid to be sprayed.
[0006] Furthermore, the sealing assembly includes Z-shaped plastic strips and rubber rings. A groove is provided at the right end of the connecting tube, and Z-shaped plastic strips are fixed inside the groove. Rubber rings are fitted onto the surface of all Z-shaped plastic strips. The rubber rings are in contact with the inner wall of the connecting cover, and the left end of the rubber rings is in contact with the right end of the connecting tube. The conical ring is located inside all the Z-shaped plastic strips. The sealing assembly seals the gap between the connecting tube and the connecting cover.
[0007] Furthermore, the filter assembly includes a support ring and a filter screen. The support ring is placed inside all the Z-shaped plastic strips, and the filter screen is fixed to the right end inside the support ring. The liquid entering the connecting cover and connecting pipe is filtered by setting the support ring and the filter screen.
[0008] Furthermore, the extrusion assembly includes an extrusion ring and a spring. The spring is fixed to the left end of the surface of the conical ring, and the extrusion ring is fixed to the left end of the spring. The left end of the extrusion ring is in contact with the right end of the filter screen, and the filter screen is fixed by setting the extrusion assembly.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This detachable and washable atomizing nozzle assembly has the following advantages: 1. The modular design of this detachable and washable atomizing nozzle assembly significantly simplifies the daily maintenance process; the threaded connection cover combined with the detachable flow guide and filter components allows users to quickly disassemble the internal structure and thoroughly clean areas prone to dirt accumulation, such as the spiral flow guide groove and conical groove, effectively avoiding clogging problems caused by impurity deposits. 2. The synergistic effect of the Z-shaped plastic strip and the rubber ring in the sealing assembly, combined with the dynamic pressure adjustment of the extrusion assembly, ensures the absolute sealing of fluid transportation under high pressure. Even after repeated disassembly and assembly, the elastic rubber ring can still fit tightly against the inner wall of the connecting cover, eliminating the risk of leakage.

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.
[0013] Please see Figure 1-3 This embodiment provides a technical solution: a detachable and washable atomizing nozzle assembly, including a connecting pipe 1 and a spray assembly 4; Connecting pipe 1: A threaded pipe 3 is fixed to the left end of the connecting pipe 1. A connecting cover 2 is threaded to the right end of the connecting pipe 1. A flow guiding component 5 is installed inside the connecting cover 2. A sealing component 6 is installed inside the right end of the connecting pipe 1. The left end of the flow guiding component 5 is connected to the sealing component 6. A filter component 7 is installed inside the sealing component 6. A squeezing component 8 is installed at the left end of the flow guiding component 5. The squeezing component 8 fits into the filter component 7. The flow guiding component 5 includes a fixing frame 51, a baffle plate 52, a connecting ring 53, an outlet 54, and a conical ring 55. Three corresponding fixing frames 51 are fixed inside the connecting cover 2. A baffle plate 52 is fixed between the three fixing frames 51. A connecting ring 53 is fixed to the left end of the baffle plate 52. Evenly distributed outlets 54 are opened on the circumferential surface of the connecting ring 53. A conical ring 55 is fixed to the left end of the connecting ring 53. The sealing component 6 includes a Z-shaped plastic strip 61 and a rubber ring 62. A groove is opened at the right end of the connecting pipe 1. Evenly distributed Z-shaped plastic strips 61 are fixed inside the groove. 1. All Z-shaped plastic strips 61 are fitted with rubber rings 62. The rubber rings 62 are in contact with the inner wall of the connecting cover 2. The left end of the rubber rings 62 is in contact with the right end of the connecting pipe 1. The conical ring 55 is located inside all Z-shaped plastic strips 61. The filter assembly 7 includes a support ring 71 and a filter screen 72. The support ring 71 is placed inside all Z-shaped plastic strips 61. The filter screen 72 is fixed to the right end inside the support ring 71. The extrusion assembly 8 includes an extrusion ring 81 and a spring 82. The spring 82 is fixed to the left end of the surface of the conical ring 55. The extrusion ring 81 is fixed to the left end of the spring 82. The left end of the extrusion ring 81 is in contact with the right end of the filter screen 72. The filter screen 72 is fixed by setting the extrusion assembly 8. The liquid entering the connecting cover 2 and the connecting pipe 1 is filtered by setting the support ring 71 and the filter screen 72. The gap between the connecting pipe 1 and the connecting cover 2 is sealed by setting the sealing assembly 6. The liquid to be sprayed is guided by setting the flow guiding assembly 5. The spray assembly 4 includes a connecting plate 41, a spray nozzle 42, a conical groove 43, and a spiral guide groove 44. The right end of the connecting cover 2 has an opening, and the connecting plate 41 is fixed inside the opening. The middle part of the connecting plate 41 has a spray nozzle 42, and the left end of the connecting plate 41 has a conical groove 43 and a uniformly distributed spiral guide groove 44. By setting the spray assembly 4, when in use, the liquid flowing out through the uniformly distributed liquid outlet 54 will be sprayed out sequentially through the spiral guide groove 44, the conical groove 43, and the spray nozzle 42, thus effectively atomizing the liquid.
[0014] The working principle of the detachable and washable atomizing nozzle assembly provided by this utility model is as follows: The liquid first enters the assembly through the external threaded pipe 3 at the left end of the connecting pipe 1. When flowing through the connecting pipe 1, the sealing assembly 6 ensures the sealing between the connecting pipe 1 and the connecting cover 2. Specifically, the rubber ring 62 supported by the Z-shaped plastic strip 61 tightly fits against the inner wall of the connecting cover 2 and the right end face of the connecting pipe 1 to prevent leakage. Subsequently, the liquid contacts the filter assembly 7. The filter screen 72 intercepts impurities under the fixation of the support ring 71, while the spring 82 of the squeezing assembly 8 continuously pushes the squeezing ring 81 to press the right end of the filter screen 72 tightly, ensuring the stability of the filter screen 72 and preventing displacement. The filtered liquid then enters the filter assembly 72. The flow guiding component 5 diverts the liquid through the evenly distributed outlets 54 on the circumference of the connecting ring 53. The conical ring 55 further guides the liquid flow to the spray component 4. When the liquid reaches the left end of the connecting plate 41, it is centrifuged by the swirling effect of the spiral guide groove 44, which accelerates the liquid through the conical groove 43 to form a high-speed vortex. Finally, the liquid is sprayed out from the spray nozzle 42 and fully atomized due to the sudden drop in pressure. Throughout the process, the blocking plate 52 is fixed inside the connecting cover 2 by the fixing bracket 51 to ensure the stability of the flow path. The detachable design of each component, such as the threaded connection between the connecting cover 2 and the connecting pipe 1, facilitates the disassembly and cleaning of the filter screen 72 and the internal flow channel, which significantly solves the problem of long-term blockage.
