Description

Technical Field

[0001] This utility model relates to the field of spray equipment technology, and more specifically, to an anti-drip nozzle for alkaline spraying. Background Technology

[0002] Alkali spraying technology has a wide range of applications in many fields, including industrial production and environmental protection, such as waste gas treatment and industrial cleaning. However, existing alkali spray nozzles have shortcomings in actual use and still need to be improved. During the alkali transportation process, the liquid delivery pipeline connection of existing nozzles is not stable enough and lacks effective sealing measures, which can easily lead to alkali leakage. This not only wastes resources but may also threaten the safety of operators.

[0003] Meanwhile, traditional nozzles suffer from uneven spraying and poor atomization in alkaline solution spraying. Some nozzles lack swirling and buffering devices, resulting in uneven distribution of the alkaline solution and uneven wetting of the sprayed area, affecting the treatment effect. Furthermore, the nozzles lack effective internal filtration devices, allowing impurities and particles in the alkaline solution to easily clog the nozzles, reducing their lifespan and spraying efficiency. Therefore, we have made improvements and proposed an anti-drip nozzle for alkaline solution spraying. Utility Model Content

[0004] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned purpose, this utility model provides the following technical solution: a drip-proof nozzle for alkaline spraying, comprising a nozzle mounting reinforcement plate, a nozzle mounting bracket mounted on the front plate of the nozzle mounting reinforcement plate, a fixing slot on the nozzle mounting bracket, bolt holes on the outer edge of the nozzle mounting reinforcement plate, a threaded sleeve for connecting a liquid infusion tube installed in the center of the top of the nozzle mounting bracket, a liquid infusion tube body at the top of the threaded sleeve for connecting the liquid infusion tube, a liquid infusion sleeve nested outside the liquid infusion tube body, a spray liquid input pipe embedded inside the liquid infusion tube body, a thickened drip-proof valve sleeve for the nozzle installed below the threaded sleeve for connecting the liquid infusion tube, and a nozzle at the bottom of the thickened drip-proof valve sleeve for the nozzle.

[0005] As a preferred technical solution of this utility model, a main nozzle mounting frame is provided below the nozzle mounting bracket.

[0006] As a preferred technical solution of this utility model, a protrusion is installed on the outer side of the nozzle mounting main frame, and there are six protrusions arranged in a ring shape. A main frame mounting hole is provided above the protrusion, and the nozzle mounting bracket is connected to the main frame mounting hole.

[0007] As a preferred technical solution of this utility model, the reinforcing plate has four bolt holes, which are located at the four corners of the nozzle mounting reinforcing plate, and a reinforcing plate mounting bolt is inserted into each of the reinforcing plate bolt holes.

[0008] As a preferred technical solution of this utility model, liquid channel sealing gaskets are connected to both sides of the spray liquid input pipe, and an alkaline spray liquid input connector is connected inside the top opening of the spray liquid input pipe, and the alkaline spray liquid input connector is located above the infusion pipe body.

[0009] As a preferred technical solution of this utility model, the nozzle anti-drip thickened valve sleeve is provided with a liquid channel sealing bushing inside, and an anti-drip locking ring is nested in the middle of the liquid channel sealing bushing.

[0010] As a preferred technical solution of this utility model, a vortex core tube is embedded inside the liquid channel sealing bushing, the top end of the vortex core tube is connected to the spray liquid input pipe, and a nozzle buffer chamber and an anti-drip spring are nested on the outer tube below the vortex core tube.

[0011] As a preferred technical solution of this utility model, a nozzle filter screen is installed inside the nozzle, and a diffusion cover is connected to the lower opening of the nozzle, and the diffusion cover is provided with diffusion atomization holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model features a thickened anti-drip valve sleeve for the nozzle. The anti-drip locking ring within the sleeve works in conjunction with the liquid channel sealing bushing. When the alkali solution stops flowing, the anti-drip locking ring tightly seals against the inner wall of the liquid channel sealing bushing, creating a good seal. Simultaneously, an anti-drip spring further enhances the seal, providing double protection to effectively prevent dripping of the alkali solution after spraying stops, avoiding waste and environmental pollution. The anti-drip function ensures full utilization of the alkali solution, reduces losses due to dripping, improves the efficiency of alkali solution use, and lowers operating costs.

[0013] This utility model features a threaded sleeve connecting the infusion tube to securely connect the tube body to the nozzle's anti-drip thickened valve sleeve. A liquid channel sealing gasket prevents leakage of the alkali solution during transport, ensuring the safe and smooth flow of the alkali solution from the input pipe into the nozzle device, thus guaranteeing the stability and reliability of the entire transport process. The vortex core tube creates a rotating liquid flow of the alkali solution, resulting in a more uniform distribution. The nozzle buffer chamber buffers and stabilizes the pressure of the alkali solution, the nozzle filter screen filters impurities, and the diffuser and diffusion atomizing holes disperse the alkali solution into fine droplets. These designs work together to achieve uniform spraying and excellent atomization of the alkali solution, improving spraying quality and work efficiency.

[0014] This utility model's sprinkler head mounting reinforcement plate, secured in its designated position via bolt holes at the four corners and mounting bolts, provides stable support for the entire sprinkler head assembly. This design ensures the sprinkler head remains stable in various complex working environments, preventing shaking or displacement and guaranteeing normal sprinkler operation. The sprinkler head mounting bracket is connected to the main sprinkler head mounting frame via mounting holes, and the protrusions on the main frame are distributed in a circular array. This layout not only facilitates installation but also evenly distributes stress, enhancing structural stability and extending the service life of the sprinkler head assembly.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] Example 1: A drip-proof nozzle for alkaline spraying includes a nozzle mounting reinforcement plate 1, a nozzle mounting bracket 2 mounted on the front plate of the nozzle mounting reinforcement plate 1, a fixing slot 3 on the nozzle mounting bracket 2, and reinforcement plate bolt holes 4 connected to the outer edge of the nozzle mounting reinforcement plate 1. A threaded sleeve 9 for connecting a liquid infusion tube is installed in the center of the top of the nozzle mounting bracket 2. A liquid infusion tube body 10 is located at the top of the threaded sleeve 9, and a liquid infusion tube sleeve 11 is nested inside the liquid infusion tube body 10. A spray liquid inlet pipe 12 is embedded inside the liquid infusion tube body 10. A thickened drip-proof valve sleeve 15 is installed below the threaded sleeve 9, and a nozzle 21 is located at the bottom of the thickened drip-proof valve sleeve 15. A main nozzle mounting frame 6 is located below the nozzle mounting bracket 2. The nozzle mounting main frame 6 has six protrusions 7 on its outer side, arranged in a ring shape. Above the protrusions 7 is a main frame mounting hole 8, and the nozzle mounting bracket 2 is connected to the main frame mounting hole 8.

[0020] There are four bolt holes 4 on the reinforcing plate, located at the four corners of the nozzle mounting reinforcing plate 1. Each bolt hole 4 is fitted with a reinforcing plate mounting bolt 5. Liquid channel sealing gaskets 13 are connected to both sides of the spray liquid inlet pipe 12. An alkaline spray liquid inlet connector 14 is connected to the top opening of the spray liquid inlet pipe 12, and the alkaline spray liquid inlet connector 14 is located above the inlet pipe body 10.

[0021] The nozzle anti-drip thickened valve sleeve 15 has a liquid channel sealing bushing 16 inside, and an anti-drip locking ring 17 is nested in the middle of the liquid channel sealing bushing 16. A swirl core tube 18 is embedded inside the liquid channel sealing bushing 16. The top end of the swirl core tube 18 is connected to the spray liquid input pipe 12. The nozzle buffer chamber 19 and the anti-drip spring 20 are nested on the outer tube below the swirl core tube 18. A nozzle filter screen 22 is installed inside the nozzle 21. A diffuser hood 23 is connected to the lower end of the nozzle 21. The diffuser hood 23 has diffusion atomization holes 24.

[0022] The working principle of the anti-drip nozzle for alkaline spraying: The nozzle mounting reinforcement plate 1 serves as the basic mounting component of the entire nozzle assembly. Four reinforcement plate bolt holes 4 at its four corners are used to install reinforcement plate mounting bolts 5. By inserting the reinforcement plate mounting bolts 5 into the corresponding mounting positions and tightening them, the nozzle mounting reinforcement plate 1 can be firmly fixed to the designated mounting surface, providing stable support for subsequent components.

[0023] The nozzle mounting bracket 2 is installed on the front plate of the nozzle mounting reinforcement plate 1, and its fixing slot 3 can be used to install with other components. The main nozzle mounting frame 6 is connected to the nozzle mounting bracket 2 through the main frame mounting hole 8 above the protrusion 7. This ring-shaped array of protrusions 7 helps to evenly distribute the force and ensure the stability of the connection.

[0024] The alkali solution enters the spray liquid inlet pipe 12 from the alkali solution spray liquid inlet connector 14. The inlet pipe sleeve 11 nested outside the inlet pipe body 10 serves to protect and fix it, preventing damage to the spray liquid inlet pipe 12 from external factors. Liquid channel sealing gaskets 13 are installed on both sides of the spray liquid inlet pipe 12, which can effectively prevent alkali solution leakage during transportation and ensure that the alkali solution can smoothly and safely enter the nozzle device.

[0025] The infusion tube connection threaded sleeve 9 is located inside the top center of the nozzle mounting bracket 2. On the one hand, it connects the infusion tube body 10 to the nozzle anti-drip thickened valve sleeve 15. On the other hand, the threaded connection ensures the sealing and stability of the connection, allowing the alkaline solution to flow smoothly from the spray liquid input pipe 12 into the nozzle anti-drip thickened valve sleeve 15.

[0026] The nozzle anti-drip thickened valve sleeve 15 has an anti-drip locking ring 17 nested in the middle of the liquid channel sealing bushing 16. When the alkali solution stops flowing in, the anti-drip locking ring 17 will, under its own elasticity or other forces, tightly adhere to the inner wall of the liquid channel sealing bushing 16, forming a sealing effect and preventing the alkali solution from continuing to flow downward, thereby preventing the nozzle from dripping.

[0027] The anti-drip spring 20 nested on the outer tube below the swirl core tube 18 also plays an auxiliary role in preventing dripping. When the alkali supply stops, the anti-drip spring 20 will exert a certain pressure on the internal components of the nozzle, helping the anti-drip locking ring 17 to better achieve a seal and further enhance the anti-drip effect.

[0028] After the alkali solution enters the vortex core tube 18 through the spray liquid inlet pipe 12, the alkali solution forms a rotating liquid flow under the action of the vortex core tube 18. This vortex can make the alkali solution more evenly distributed. The nozzle buffer chamber 19 plays a role in buffering and stabilizing the pressure of the alkali solution, so that the alkali solution enters the nozzle 21 with a relatively stable pressure and flow rate.

[0029] The nozzle filter 22 inside the nozzle 21 can filter out impurities and particles in the alkaline solution, preventing these impurities from clogging the nozzle or affecting the spraying effect. After the alkaline solution flows out of the nozzle 21, it enters the diffuser 23. The diffusion and atomization holes 24 on the diffuser 23 disperse the alkaline solution into fine droplets, realizing the spraying and atomization of the alkaline solution, thereby achieving the purpose of effectively spraying the target area.

[0030] The working process of the anti-drip nozzle for alkaline spraying is as follows: First, place the nozzle mounting reinforcement plate 1 on the pre-determined mounting surface. Next, insert the reinforcement plate mounting bolts 5 into the bolt holes 4 and tighten them with a tool to firmly fix the nozzle mounting reinforcement plate 1 on the mounting surface, providing stable support for subsequent components. Install the nozzle mounting bracket 2 on the front plate of the nozzle mounting reinforcement plate 1, ensuring accurate installation.

[0031] Connect the main frame 6 of the nozzle mounting bracket to the nozzle mounting bracket 2 through the main frame mounting hole 8 above its protrusion 7. Since the protrusions 7 are arranged in a ring-shaped array, a stable connection and even force distribution are ensured. Securely connect the infusion tube body 10 to the top center of the nozzle mounting bracket 2 through the infusion tube connecting threaded sleeve 9, while ensuring that the infusion tube sleeve 11 is nested outside the infusion tube body 10 for protection. Connect the alkaline spray liquid inlet connector 14 to the external alkaline supply system, ensuring a good seal.

[0032] The external alkali supply system is activated, and alkali enters the spray liquid inlet pipe 12 from the alkali spray liquid inlet connector 14. The liquid channel sealing gasket 13 prevents alkali from leaking from both sides of the spray liquid inlet pipe 12 during transportation, ensuring that the alkali flows safely and smoothly into subsequent components.

[0033] When the alkali solution is being input normally, the pressure of the alkali solution overcomes the resistance of the anti-drip locking ring 17 and the anti-drip spring 20, allowing the alkali solution to smoothly pass through the liquid channel sealing bushing 16 and enter the vortex core tube 18. At this time, the anti-drip locking ring 17 is in the open state, which does not hinder the flow of the alkali solution.

[0034] When the alkali solution stops flowing in, the anti-drip locking ring 17, under its own elasticity, tightly adheres to the inner wall of the liquid channel sealing bushing 16, forming a seal. At the same time, the anti-drip spring 20 applies a certain pressure to the internal components of the nozzle, assisting the anti-drip locking ring 17 in achieving a better sealing effect, preventing the alkali solution from continuing to flow downwards, thereby preventing dripping from the nozzle.

[0035] After the alkali solution enters the cyclone core tube 18, it forms a rotating liquid flow under the action of the cyclone core tube 18, making the alkali solution more evenly distributed.

[0036] The nozzle buffer chamber 19 buffers and stabilizes the pressure of the alkaline solution, ensuring that it enters the nozzle 21 at a stable pressure and flow rate. After entering the nozzle 21, the nozzle filter 22 filters out impurities and particles, preventing clogging or affecting the spraying effect. The filtered alkaline solution flows out of the nozzle 21 and into the diffuser hood 23. The diffusion and atomization holes 24 on the diffuser hood 23 disperse the alkaline solution into fine droplets, achieving spraying and atomization of the alkaline solution for effective spraying of the target area.

[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
