Description

Technical Field

[0001] This application relates to the field of nozzle technology, and more particularly to a dry fog self-cleaning nozzle. Background Technology

[0002] Dry fog dust suppression equipment utilizes the principle of water and air combination, atomizing ultra-fine water mist through nozzles to cause dust particles to quickly adhere, increase in weight, and then naturally settle, making it the mainstream dust suppression solution.

[0003] However, existing dry fog nozzle equipment faces significant bottlenecks in practical applications: most operating environments are harsh, and some areas have water sources with high hardness, which easily leads to the precipitation of lime scale, impurities, and excessive particulate matter content, which can easily cause nozzle clogging, atomization effect reduction, or even complete failure, directly affecting the operational stability of the dust suppression system. More importantly, nozzle clogging requires manual disassembly and cleaning, which not only interrupts the normal operation process but also increases labor and time costs. Frequent maintenance leads to a decline in the overall operating efficiency of the equipment. Therefore, to solve the above problems, we provide a dry fog self-cleaning nozzle. Utility Model Content

The lower end of the cylinder assembly is fixedly connected to the upper end of the fixed rod assembly. The cleaning needle is sleeved inside the fixed rod assembly and is assembled inside the upper end of the dry fog nozzle.

[0006] Preferably, one end of the water-through-wall connector is connected to a water pipe connector, and a water pipe fitting is connected to the water pipe connector.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0016] Please see Figure 1-5 This utility model provides a technical solution for a dry fog self-cleaning nozzle: A dry fog self-cleaning nozzle includes a cylinder assembly 4, a fixing rod assembly 2, a housing assembly 17, a dry fog nozzle 1, a water-through-wall connector 7, a bellows connector 16, and a cleaning needle 3. The lower end of the cylinder assembly 4 is fixedly connected to the upper end of the fixing rod assembly 2. The cleaning needle 3 is housed inside the fixing rod assembly 2 and is mounted inside the upper end of the dry fog nozzle 1. Specifically, the cylinder assembly 4 provides a stable driving force for the movement of the cleaning needle 3. The fixing rod assembly 2 not only provides a stable mounting support for the cleaning needle 3 but also guides its movement trajectory to prevent deviation and incomplete cleaning. The cleaning needle 3 is adapted to the internal structure of the dry fog nozzle 1 and can penetrate deep into the nozzle to remove scale and impurities, solving the clogging problem. The dry fog nozzle 1 adopts a high-efficiency atomization design, improving the water-air mixing efficiency and water mist fineness, enhancing the dust suppression effect. The water-through-wall connector 7 ensures the sealing reliability of the water supply passage and prevents water leakage from affecting equipment operation.

[0017] In this embodiment, one end of the water-through-wall connector 7 is connected to a water pipe connector 5, and a water pipe fitting 6 is connected to the water pipe connector 5. The outer shell assembly 17 includes a mounting flange 18, which is fixedly installed on the outer shell assembly 17. The outer shell assembly 17 internally accommodates part of the structure of the cylinder assembly 4. A rear dust cover 19 is provided at the end of the outer shell assembly 17, and the rear dust cover 19 is detachably connected to the outer shell assembly 17. One end of the corrugated pipe connector 16 is connected to one end of the rear dust cover 19, and one end of the dry fog nozzle 1 is connected to a nozzle connector. Specifically, the water-through-wall connector 7, the water pipe connector 5, and the water pipe fitting 6 form a highly sealed water supply path, which can adapt to different water quality scenarios and reduce the probability of impurity deposition. The mounting flange 18 of the outer shell assembly 17 facilitates the quick fixing of the equipment in construction sites, mines, and other scenarios, improving the ease of installation. The outer shell assembly 17 provides protection for the key structure of the cylinder assembly 4. The detachable design of the rear dust cover 19 not only prevents dust from entering the internal components but also facilitates later inspection and maintenance.

[0018] In this embodiment, the cylinder assembly 4 includes an air pipe connector 8, an air pipe fitting 9, and an air-to-wall connector 10. The air pipe connector 8 is connected to the cylinder assembly 4, and the air pipe connector 8 is connected to the air-to-wall connector 10 through the air pipe fitting 9. The cylinder assembly 4 is also connected to a control air-opening pipe structure, which includes a control air-opening pipe connector 11, a control air-opening pipe 12, a first control air-opening wall connector 14, and a second control air-opening wall connector 15. The control air-opening pipe connector 11 is connected to the cylinder assembly 4, and the cylinder assembly 4 is also provided with a cylinder-closing pipe connector 13, which is connected to an external air pipe. Specifically, the air pipe connector 8, the air pipe fitting 9, and the air-to-wall connector 10 form a high-efficiency air circuit system, providing sufficient air pressure for dry fog atomization and powering the cylinder assembly 4. In the control air-opening pipe structure, the cylinder-closing pipe connector 13 cooperates with the external air pipe to control the cylinder assembly 4 to reset, so that the cleaning needle 3 operates continuously.

[0019] Working principle: First, the water supply system is connected through the water inlet connector 7, and forms a passage through the water pipe connector 5 and the water pipe fitting 6 to deliver water to the atomization area where the fixed rod assembly 2 and the nozzle connector are located. At the same time, the air system is started. Compressed gas enters through the air pipe connector 8 of the cylinder assembly 4, and completes the air passage through the air pipe fitting 9 and the air inlet connector 10 to provide power for atomization and subsequent cleaning actions. When the water and air are fully mixed inside the dry fog nozzle 1, they are atomized through the nozzle under the action of air pressure to form an ultra-fine water mist. The water mist combines with the dust particles in the working area, causing them to increase in weight and settle naturally, thus achieving a dust suppression effect.

[0020] When the equipment detects a decrease in atomization effect or the need for periodic cleaning, it triggers an action by controlling the air-opening pipe structure. After receiving a signal, the air-opening pipe connector 11 transmits instructions through the air-opening pipe 12, the first control opening through-wall connector 14, and the second control opening through-wall connector 15, causing the cylinder assembly 4 to drive the cleaning needle 3 to start working. During cleaning, the cylinder assembly 4 drives the cleaning needle 3 to retract upwards, and its lower end sequentially inserts into the fixed rod assembly 2 and the nozzle connector to mechanically clean the scale or impurities inside the dry fog nozzle 1, thoroughly removing the blockage. After cleaning, the external air pipe connected to the cylinder shut-off pipe connector 13 supplies air, controls the cylinder assembly 4 to reset, and the cleaning needle 3 returns to its initial position, restoring the equipment to normal atomization and dust suppression state.
