Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in mining, specifically to an intelligent controllable rotary nozzle for dust suppression spraying, which is particularly suitable for efficient and adaptive dust removal operations in harsh working environments such as mines. Background Technology

[0002] Dust pollution is a critical issue seriously affecting safe production and occupational health during mining, transportation, and other operations. Currently, widely used traditional spray dust suppression devices generally suffer from the following technical defects: First, their spray patterns are relatively simple, making it difficult to adapt to dynamic changes in dust particle size, concentration, and environmental conditions in different work areas. This results in a single nozzle failing to achieve ideal atomization coverage and dust collection effects under various working conditions, often requiring frequent nozzle type changes depending on the scenario. This not only increases equipment maintenance costs but also leads to operational interruptions, impacting overall production efficiency. Second, existing spray devices rely heavily on manual operation for adjustment, lacking intelligent functions for automatic adjustment based on real-time environmental parameters (such as dust concentration and air humidity). This results in low dust suppression efficiency, water waste, and unstable dust suppression effects.

[0003] Therefore, there is an urgent need to develop a spray nozzle with multi-mode switching and intelligent control functions to improve the adaptability and overall operating efficiency of the dust removal system. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an intelligent controllable rotary nozzle for dust suppression spraying, aiming to solve the technical problems of existing nozzles having a single atomization mode, low level of intelligence, and poor adaptability, and to achieve a highly efficient dust removal function with "one-click switching and intelligent adaptation".

[0005] The technical solution of this utility model is as follows: This utility model discloses an intelligent controllable rotary nozzle for dust suppression spraying, which mainly includes a nozzle body, a rotary valve core, a sensor controller, an air inlet pipe, a vortex guide chamber, an intelligent control module, a detachable atomizing nozzle, and connected external sensors. The nozzle body, as the core load-bearing structure, is cylindrical in shape, with a precisely machined cylindrical cavity inside. This cavity is used to install the rotary valve core, providing a stable installation space and ensuring its rotational accuracy. One end of the nozzle body has a circular spray outlet for connecting the detachable atomizing nozzle, facilitating subsequent maintenance and replacement. The other end has a liquid inlet for connecting to an external water supply pipeline via fittings, achieving a stable water supply.

[0006] The rotary valve core is rotatably mounted within the receiving cavity of the nozzle body. Four media inlets are arranged in an array around its axis on its end face near the nozzle body. Each inlet precisely corresponds to one of four preset atomizing channels within the rotary valve core. The outlets of the four atomizing channels are located at one end of the detachable atomizing nozzle and are coaxial with the inlets, ensuring smooth media flow. Through a set rotation angle and control action, the rotary valve core can drive any one of the four media inlets to align with the liquid inlet of the nozzle body, while simultaneously aligning the outlet of the corresponding atomizing channel with the detachable atomizing nozzle, achieving precise switching between different atomization modes.

[0007] The sensor controller is integrated inside the rotary valve core and is connected to it via a built-in gear transmission mechanism. It drives the valve core to rotate around its axis, ensuring smooth and reliable rotation. The sensor controller uses a waterproof stepper motor or servo motor to achieve precise control of the rotation angle. Every 90° rotation of the rotary valve core aligns a specific medium inlet with the liquid inlet of the nozzle body, thereby opening the corresponding atomization channel and simultaneously closing other channels. This enables rapid and accurate switching between different atomization modes, meeting the rapid response requirements under various operating conditions.

[0008] Four atomizing channels are integrated inside the rotary valve core, including a standard atomization channel, a fan-shaped atomization channel, a cone-shaped atomization channel, and a high-pressure air-assisted atomization channel. This diverse channel design adapts to various dust removal scenarios. The standard atomization channel is a straight cylindrical passage that forms basic spherical atomization as water flows through, suitable for general dust suppression scenarios and ensuring basic dust removal effectiveness. The fan-shaped atomization channel is designed with a flat, narrow slit-like outlet, producing a wide, uniform fan-shaped water curtain, suitable for suppressing large-area open dust and improving large-area dust removal efficiency.

[0009] The conical atomization mode integrates a vortex guide chamber within its flow channel. This chamber is a cylindrical cavity with helical guide vanes fixed inside. When water flows through, it forms a high-speed rotating flow guided by the helical structure. Due to centrifugal force, it exits from the outlet, forming a hollow conical mist field. The atomization cone angle can be finely adjusted by regulating the water supply pressure, exhibiting excellent penetration and envelopment characteristics, enhancing adaptability to complex dusty environments. The high-pressure air-assisted atomization mode also features a straight cylindrical flow channel, but a gas flow channel is integrated within its middle section. This gas flow channel is connected to an external high-pressure air source via an air inlet pipe. When switching to this mode, high-pressure gas is injected through the air inlet pipe, intensely mixing and colliding with the water flow within the channel. The kinetic energy of the gas tears the water flow into numerous fine droplets, significantly improving the collection efficiency of inhalable fine dust. A threaded quick-connect fitting is fitted to the end of the air inlet pipe extending to the outside of the nozzle body, facilitating a quick and sealed connection to an external air compressor pipeline, improving the ease of equipment installation and maintenance.

[0010] The intelligent control module is encapsulated in a waterproof and explosion-proof sealed box and integrated inside or on the side of the nozzle body, adapting to the harsh working environment of mines. Internally, the module contains core components such as a microprocessor, memory chip, and wireless communication module. The intelligent control module is electrically connected to the sensor controller via a bus to ensure stable transmission of control commands. Simultaneously, its input interface can connect to external sensors located in dust removal areas (such as tunneling faces and conveyor belt transfer points), including laser dust concentration sensors and air humidity sensors, to achieve comprehensive collection of environmental parameters. The intelligent control module pre-stores atomization mode decision algorithms based on environmental parameters (such as dust concentration thresholds and humidity thresholds), providing algorithmic support for intelligent control.

[0011] The beneficial effects of this utility model are: This invention, through a rotary valve core and multi-channel integrated design, achieves rapid and reliable switching between four modes: ordinary atomization, high-pressure air-assisted atomization, fan-shaped spray, and cone atomization. It can flexibly adapt to the dust removal needs of different dust characteristics and diffusion conditions in complex operating environments such as mines, effectively expanding the operating range of a single device. The closed-loop control system, composed of an integrated intelligent control module and external sensors, can automatically select and switch to the optimal atomization mode based on real-time collected dust concentration and humidity data using a built-in algorithm. This significantly reduces the frequency of manual intervention, improves the intelligence level and response speed of dust removal operations, and helps save water resources and energy, thereby improving overall dust suppression efficiency. Furthermore, the detachable atomizing nozzle and quick-connect structure design make equipment maintenance and component replacement more convenient, further reducing long-term operating costs and enhancing continuous operation capability and reliability in harsh environments.

Detailed Implementation

[0014] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0015] Example This utility model relates to an intelligent adjustable rotary nozzle for dust suppression spraying. (See also:) Figure 1 The system mainly consists of a nozzle body 1, a rotary valve core 2, a sensor controller 4, an air inlet pipe 5, a vortex guide chamber 6, an intelligent control module 7, a detachable atomizing nozzle, and connected external sensors 8. The nozzle body 1, as the core load-bearing structure, is cylindrical in shape and has a precisely machined cylindrical cavity inside for mounting the rotary valve core 2. One end of the nozzle body 1 has a circular spray outlet for connecting the detachable atomizing nozzle, and the other end has a liquid inlet for connecting to an external water supply line via fittings. The rotary valve core 2 is rotatably mounted within the cavity of the nozzle body 1. Four media inlets 3 are arranged in an array around its axis on its end face near the nozzle body 1. Each inlet precisely corresponds to one of the four pre-set atomizing channels inside the rotary valve core 2. Figure 1 and Figure 6 The outlets of the four atomizing channels are located at one end of the detachable atomizing nozzle and are coaxial with the inlet. The rotary valve core 2 can drive any one of the four medium inlets 3 to align with the liquid inlet of the nozzle body 1 by setting the rotation angle and control action, and at the same time, the outlet of the corresponding atomizing channel is aligned with the detachable atomizing nozzle.

[0016] See Figure 1 and Figure 2 The sensor controller 4 is integrated inside the rotary valve core 2. It is connected to the rotary valve core 2 through a built-in gear transmission mechanism and is used to drive the valve core to rotate around its axis. The sensor controller 4 can use a waterproof stepper motor or a servo motor to achieve precise control of the rotation angle. Every 90° rotation of the rotary valve core 2 aligns a specific medium inlet 3 with the liquid inlet of the nozzle body 1, thereby opening the corresponding atomization channel and closing other channels, realizing rapid and accurate switching between different atomization modes.

[0017] The four atomization channels are integrated inside the rotary valve core 2. These include a normal atomization mode channel, a fan-shaped atomization mode channel, a cone-shaped atomization mode channel, and a high-pressure gas-assisted atomization mode channel.

[0018] The standard atomization mode channel is a straight cylindrical channel that forms basic spherical atomization as water flows through it, suitable for routine dust suppression. The fan-shaped atomization mode channel is designed with a flat, narrow slit-like outlet, producing a wide, uniform fan-shaped water curtain, suitable for suppressing large-area open dust. The conical atomization mode channel integrates a vortex guide chamber 6, see [link to relevant documentation]. Figure 4 The guide chamber is a cylindrical cavity with helical guide vanes fixed inside. When water flows through, it forms a high-speed rotating flow guided by the helical structure. Due to centrifugal force, it is ejected from the outlet, forming a hollow conical mist field. The atomization cone angle can be finely adjusted by regulating the water supply pressure, exhibiting excellent penetration and envelopment characteristics. The high-pressure gas-assisted atomization mode also uses a straight cylindrical channel, but a gas channel is integrated within its middle section. (See...) Figure 3 The gas flow channel is connected to an external high-pressure gas source via the air inlet pipe 5. When switching to this mode, high-pressure gas is injected through the air inlet pipe 5, where it mixes and collides intensely with the water flow in the channel. The kinetic energy of the gas tears the water flow into a large number of fine droplets, significantly improving the collection efficiency of inhalable fine dust. The end of the air inlet pipe 5 extending to the outside of the nozzle body 1 is equipped with a threaded quick connector, facilitating a quick and sealed connection with the external air compressor pipeline.

[0019] The intelligent control module 7 is encapsulated in a waterproof and explosion-proof sealed box and integrated inside or on the side of the nozzle body 1. See Figure 5. This module contains a microprocessor, a memory chip, and a wireless communication module. The intelligent control module 7 is electrically connected to the sensor controller 4 via a bus, and its input interface can connect to external sensors 8 located in the dust removal area (such as the tunneling face or conveyor belt transfer point), including laser dust concentration sensors and air humidity sensors. The intelligent control module 7 has a pre-stored atomization mode decision algorithm based on environmental parameters (such as dust concentration thresholds and humidity thresholds).

[0020] During the operation of the dust removal system, external sensors 8 continuously collect real-time data on dust concentration and air humidity in the work area and transmit it to the intelligent control module 7 via wired or wireless means. The microprocessor within the module analyzes and processes the received signals and calls a preset decision algorithm to determine the optimal atomization mode required under the current environmental conditions. Subsequently, the intelligent control module 7 generates corresponding control commands and sends them to the sensor controller 4. The sensor controller 4 drives the rotary valve core 2 to rotate to a predetermined angle according to the commands, aligning the corresponding medium inlet with the water supply passage and the outlet with the detachable atomizing nozzle, thereby activating the flow channel corresponding to the selected atomization mode and completing the automatic mode switching. The entire control process forms a closed loop, realizing adaptive adjustment according to environmental changes. At the same time, the intelligent control module 7 can also record operating data, maintenance cycles, and other information, and upload the data to a remote monitoring center via wireless communication, facilitating equipment management and status monitoring, and further improving the intelligence and management level of the dust removal system.
