Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, and more specifically, it relates to an anti-clogging dual-stage filtration fine water mist nozzle. Background Technology

[0002] As a core component in fire fighting, agricultural irrigation and industrial dust suppression, the anti-clogging performance of fine water mist nozzles directly determines the reliability and lifespan of the system. However, industry data shows that the system failure rate caused by nozzle clogging is as high as 22%. In water sources containing suspended solids or high hardness, the average maintenance cycle is shortened to 3 months, and the cost of a single cleaning accounts for more than 40% of the equipment operation and maintenance costs.

[0003] In existing technologies, traditional nozzles use a vertical single-stage filter design, which traps impurities that easily accumulate on the filter surface, causing the water flow area to decrease rapidly. This necessitates frequent shutdowns for cleaning, making it inconvenient to clean. If not cleaned in time, it can easily cause nozzle blockage. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides an anti-clogging dual-stage filtration fine water mist nozzle to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging dual-stage filtration fine water mist nozzle, comprising a nozzle body, the nozzle body including a nozzle, an atomizing plate at the bottom of the nozzle, a connecting pipe on the nozzle, a water pipe on the connecting pipe, an air mounting pipe on the nozzle, an air inlet pipe connected to one end of the air mounting pipe, a filter barrel on the connecting pipe, a first filter screen at the bottom of the filter barrel, a second filter screen on the side wall, a water passage circumferentially provided on the connecting pipe, a filter screen inclinedly provided on the water pipe, a cleaning pipe on the water pipe, and a cleaning sleeve threadedly connected to the cleaning pipe.

[0008] The present invention is further configured such that the connecting pipe is provided with a sliding groove and a sliding rod, and the two sides of the filter bucket are provided with sliding plates on the sliding rod, thereby driving the filter bucket to adjust its position within the connecting pipe.

[0009] The present invention is further provided with a sliding spring between the sliding plate and the sliding groove, which facilitates the movement and resetting of the filter barrel.

[0010] The present invention is further provided with a sealing gasket between the connecting pipe and the nozzle, and a sealing groove on the connecting pipe that cooperates with the sealing gasket, thereby improving the sealing performance of the connection between the sealing gasket and the connecting pipe.

[0011] The present invention is further configured such that the sealing gasket is provided with a sealing ring and the nozzle is provided with a sealing groove that cooperates with the sealing ring, thereby improving the connection and sealing performance between the sealing gasket and the nozzle.

[0012] The present invention is further configured such that an air chamber is provided between the connecting pipe and the nozzle, and an airflow mesh plate is provided in the air chamber to facilitate gas filtration.

[0013] The present invention is further configured such that the nozzle is provided with a variable diameter groove, which facilitates the increase of the water flow velocity in the nozzle body.

[0014] The present invention is further configured such that an air inlet channel is provided circumferentially between the air chamber and the variable diameter groove, which facilitates the injection of high-pressure gas into the nozzle body, and the water flow is atomized and sprayed out in conjunction with the water flow and the atomizing plate.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an anti-clogging dual-stage filtration fine water mist nozzle, which has the following beneficial effects:

[0017] 1. The inclined filter screen facilitates primary filtration of impurities in the water pipes. The cleaning sleeve facilitates the cleaning of the filtered impurities. The filter bucket forms a secondary filtration system, further improving the service life of the nozzle body and preventing the filter nozzle from clogging.

[0018] 2. When the filter canister is not clogged, the water is filtered through the first filter screen. When the filter canister is clogged, it moves on the sliding rod under the impact of the water flow, opening the water passage. After being filtered through the second filter screen, the water flows out through the water passage, thereby improving the anti-clogging ability of the nozzle body.

[0019] 3. High-pressure gas is introduced into the nozzle body through the air inlet pipe and the air installation pipe. The gas is filtered through the air chamber and the airflow mesh plate. The water flow through the air inlet channel is atomized by the atomizing plate to form a fine water mist. By setting the variable diameter groove, the flow velocity of the water in the nozzle body is increased, which further improves the atomization effect. Attached Figure Description

[0029] Please see Figures 1-5A clog-resistant dual-stage filtration fine water mist nozzle includes a nozzle body 1, a nozzle 2, an atomizing plate 3 at the bottom of the nozzle 2, a connecting pipe 4 on the nozzle 2, a water pipe 5 on the connecting pipe 4, an air mounting pipe 6 on the nozzle 2, an air inlet pipe 7 connected to one end of the air mounting pipe 6, a filter barrel 8 on the connecting pipe 4, a first filter screen 9 at the bottom of the filter barrel 8, a second filter screen 10 on the side wall, a water passage 11 circumferentially on the connecting pipe 4, a filter screen 12 inclinedly on the water pipe 5, a cleaning pipe 13 on the water pipe 5, a cleaning sleeve 14 threadedly connected to the cleaning pipe 13, a sliding groove 15 and a sliding rod 16 on the connecting pipe 4, sliding plates 17 sliding on the sliding rod 16 on both sides of the filter barrel 8, and a sliding spring 18 between the sliding plate 17 and the sliding groove 15.

[0030] In this embodiment, when water enters the nozzle body 1, it first undergoes primary filtration through the filter screen 12. The filter screen 12 is arranged at an angle, which facilitates the entry of impurities into the cleaning pipe 13 and cleaning sleeve 14 under the impact of the water flow. The cleaning sleeve 14 collects and processes the impurities. After primary filtration, the water enters the connecting pipe 4 and is filtered through the first filter screen 9 of the filter barrel 8. When the first filter screen 9 of the filter barrel 8 is partially blocked, under the impact of the water flow, the filter barrel 8 drives the sliding plate 17 to move downward along the sliding rod 16 and compress the sliding spring 18. When the filter barrel 8 moves downward, the second filter screen 10 is aligned with the water inlet end of the water passage 11. After the water flows through the second filter screen 10, it enters the water passage 11 and flows out, thereby improving the nozzle body 1's ability to withstand blockage. After the filter barrel 8 is maintained and cleaned, the sliding plate 17 is reset under the elastic force of the sliding spring 18, and the filter barrel 8 blocks the water inlet end of the water passage 11, allowing the water to be filtered along the first filter screen 9.

[0031] Please see Figure 3-5 As one embodiment of the nozzle body 1: a sealing gasket 19 is provided between the connecting pipe 4 and the nozzle 2, a sealing groove 20 that cooperates with the sealing gasket 19 is provided on the connecting pipe 4, a sealing ring 21 is provided on the sealing gasket 19, a sealing groove 22 that cooperates with the sealing ring 21 is provided on the nozzle 2, an air chamber 23 is provided between the connecting pipe 4 and the nozzle 2, an airflow mesh plate 24 is provided in the air chamber 23, a diameter changing groove 25 is provided on the nozzle 2, and an air inlet channel 26 is provided circumferentially between the air chamber 23 and the diameter changing groove 25.

[0032] More specifically, the sealing ring 21 and sealing groove 20, as well as the sealing ring 21 and sealing groove 22, improve the sealing performance of the connection between the connecting pipe 4 and the nozzle 2. The water flows through the dual-stage filtration and enters the variable diameter groove 25. The diameter of the variable diameter groove 25 gradually increases from large to small and then gradually increases, thereby increasing the flow velocity of the water at the variable diameter groove 25. The air pipe 6 is threadedly connected to the nozzle 2. High-pressure gas is introduced into the air pipe 6 through the air inlet pipe 7. After being filtered by the air inlet mesh plate in the air chamber 23, the gas flows into the variable diameter groove 25 through the air inlet channel 26 and is atomized and sprayed out in conjunction with the atomizing plate 3.

[0033] In summary, during use or operation of the overall equipment: when water enters the nozzle body 1, it first undergoes primary filtration through the filter screen 12. The filter screen 12 is arranged at an angle, allowing impurities to easily enter the cleaning pipe 13 and cleaning sleeve 14 under the impact of the water flow. The cleaning sleeve 14 then collects and processes the impurities. After primary filtration, the water enters the connecting pipe 4 and is filtered through the first filter screen 9 of the filter barrel 8. When the first filter screen 9 of the filter barrel 8 is partially clogged, the filter barrel 8 slides under the impact of the water flow. The plate 17 moves downward along the sliding rod 16 and compresses the sliding spring 18. When the filter barrel 8 moves downward, the second filter screen 10 is aligned with the water inlet end of the water passage 11. After the water flows through the second filter screen 10, it enters the water passage 11 and flows out, thereby improving the anti-clogging ability of the nozzle body 1. After the filter barrel 8 is maintained and cleaned, the sliding plate 17 is reset under the elastic force of the sliding spring 18, and then the water inlet end of the water passage 11 is blocked by the filter barrel 8, so that the water flows along the first filter screen 9 for filtration.

[0034] The cooperation between sealing ring 21 and sealing groove 20, as well as the cooperation between sealing ring 21 and sealing groove 22, improves the sealing performance of the connection between connecting pipe 4 and nozzle 2. Water flows through a double-stage filter and enters the variable diameter groove 25. The diameter of variable diameter groove 25 gradually increases from large to small and then gradually increases, thereby increasing the flow velocity of water at variable diameter groove 25. The installation air pipe 6 is threadedly connected to nozzle 2. High-pressure gas is introduced into the installation air pipe 6 through air inlet pipe 7. After being filtered by the air inlet mesh plate in air chamber 23, the gas flows into the variable diameter groove 25 through air inlet channel 26 and is atomized and sprayed out in cooperation with atomizing plate 3.
