Description

Technical Field

[0001] This invention relates to the fields of energy conservation, environmental protection, and dust suppression technology, specifically to an environmentally friendly micron-level dust suppression fog cannon. Background Technology

[0002] Fog cannons (also known as mist cannons or dust suppression fog cannons) are environmentally friendly dust suppression devices widely used in construction sites, mines, coal yards, and other locations. They effectively suppress dust dispersion by atomizing water through a high-pressure spray system. With rapid urbanization and increasingly stringent environmental regulations, dust suppression has become a key task in construction site management. However, existing fog cannon technologies still have the following drawbacks: Specifically, dust suppression at construction sites primarily relies on spraying, which increases air humidity through high-pressure spraying equipment (such as fog cannons) to inhibit dust dispersion. However, spraying and wet methods rely heavily on water resources, resulting in significant water waste for continuous dust suppression operations. Furthermore, this approach is unsustainable in water-scarce areas and greatly increases construction costs, leading to low cost-effectiveness. Furthermore, spray evaporates rapidly in high temperatures or strong winds, drastically reducing its dust suppression effectiveness over large areas. Repeated spraying to achieve the same dust reduction standards wastes both water and electricity, resulting in poor performance. Therefore, how to efficiently and rationally utilize sustainable, renewable, and "zero-fee" water resources for intelligent dust suppression is a pressing issue. Further analysis reveals that traditional dust suppression methods have low efficiency in capturing PM2.5 and other fine particulate matter, and corresponding monitoring and mitigation measures are inadequate, posing a significant challenge to dust control at construction sites. While micron-level spray dust suppression can effectively address the settling or elimination of PM2.5 and other fine particulate matter, micron-level atomizing nozzles often use threaded connections. Although this technology is mature, the high pressure of the water flow leads to high leakage risks, high maintenance costs, and a high dependence on skilled workers. Achieving convenient installation while ensuring zero leakage, extremely high safety, and real-time monitoring of sealing surface pressure and media leakage to meet the requirements of effective dust suppression is also a crucial issue that urgently needs to be addressed.

[0012] To achieve convenient installation of the atomizing nozzle while ensuring zero leakage, extremely high safety, and real-time monitoring of sealing surface pressure and media leakage, and to meet the requirements of effective dust suppression and reduction measures that extend service life, this invention adopts a further preferred technical solution: the adjustment structure includes a connecting part, a piezoelectric sensor, and an LED display screen; the connecting part is a hollow structure, located at the input end of the atomizing nozzle, and the two are integrally formed; the piezoelectric sensor is located on the end face of the connecting part; the atomizing nozzle is located at the center of the second electromagnet, and the two are connected by a thread; the LED display screen is located on the outer wall of the housing and is connected to the piezoelectric sensor; in the initial state of connection between the first and second electromagnets, the piezoelectric sensor monitors a parameter value of 0; when the atomizing nozzle continues to rotate downwards for enhanced pressing, the piezoelectric sensor monitors a parameter value ranging from 1 to 10.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] It should be noted that, in specific embodiments of the present invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any actual relationship or order between these entities or operations. Furthermore, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0020] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "equipped" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] Example: Figures 1 to 9 As shown: An environmentally friendly micron-level dust suppression fog cannon includes a housing 1 and a fog cannon 2 mounted on the housing 1. To ensure that the fog cannon 2 can rotate at a preset angle to adapt to precise and efficient dust suppression at different dust diffusion points, this invention adopts a preferred technical solution: as follows... Figure 1 and Figure 2 As shown: A base 101 is provided above the housing 1, and the two can be fixed together by welding. A rotating structure 102 is also provided between the base 101 and the fog cannon 2. The rotating structure 102 includes a rotating disk 103, a rotating shaft 104, a fixed column 105, and a rotating motor 106. The rotating disk 103 is set on the base 101, and the two are allowed to rotate relative to each other but cannot move relative to each other; this can be achieved by keyway cooperation, which is existing technology and will not be described in detail. The fixed column 105 extends vertically on the rotating disk 103 and is connected to the fog cannon 2 through a U-shaped frame; the fixed column and the U-shaped frame are an integral structure, forming a Y shape. The bottom end of the fixed column and the rotating disk can be fixed together by welding. In addition, to enhance stability, a reinforcing rib can be provided between the rotating disk and the fixed column. The rotating shaft 104 extends vertically downward on the base 101, and its top end is fixed to the rotating disk by welding. The rotating motor 106 is set inside the base 101 and connected to the rotating shaft 104. With this setup, the rotating motor is a servo-controlled motor, which facilitates stable control of the rotation speed and angle. It can also be connected to a reducer for speed reduction. When the rotating motor starts, it drives the rotating shaft to rotate synchronously, which in turn drives the rotating disk and the fixed column to deflect synchronously. Ultimately, this causes the fog cannon to deflect at an overall angle, completing the dust suppression operation within the designated area.

[0022] like Figure 1 As shown: In order to further enhance the spraying distance and dust suppression effect of the fog cannon, the present invention adopts a further preferred technical solution: a telescopic device 107 is provided between the rotating disk 103 and the fog cannon 2, and the telescopic device 107 adopts a hydraulic telescopic rod.

[0023] like Figure 1As shown: In this embodiment, the box 1 has a square structure and is equipped with multiple evenly distributed liquid collection tanks 3. The structure of the box is large enough, and the dimensions of the box and the liquid collection tanks are specifically designed according to the needs of the construction site, with the aim of ensuring sufficient convenience and a sufficient amount of "free" water. Figure 2 As shown: The liquid collection tank 3 completes the contraction and expansion movements through the drive component 4. In the initial state, multiple liquid collection tanks 3 contract, and the outer surface of the liquid collection tank 3 is flush with the box body 1; in the liquid collection state, multiple liquid collection tanks 3 expand outward synchronously to the preset position. In order to achieve the overall storage effect of the fog cannon in the non-collecting rainwater state, ensuring the integrity of the whole; and to achieve the purpose of freely switching between two modes of the fog cannon collecting rainwater as a sustainable, zero-cost water source for environmentally friendly dust suppression and dust reduction, and to improve convenience and automation, the present invention adopts a preferred technical solution: as follows Figure 6 As shown: The driving component 4 includes a drive motor 401, a drive shaft 402, a driving wheel 403, a driven wheel 404, and a transmission rod 405. The drive motor 401 is fixedly installed at the center of the housing 1 via a bracket, and the drive motor is also a servo-controlled motor. The drive shaft 402 is vertically connected to the drive motor 401; the driving wheel 403 is sleeved on the drive shaft 402, and the driven wheel 404 is located at the end of the transmission rod 405, and the two are fixedly welded together. The transmission rod 405 is a threaded rod structure and is rotatably connected to the collection tank 3; a "screw and nut" structure is formed between the collection tank and the transmission rod. The driving wheel 403 and the driven wheel 404 are matched and installed; and both the driving wheel 403 and the driven wheel 404 adopt a helical gear structure. In a preferred embodiment, the driving wheel and the driven wheel mesh and transmit power, and a protective cover is provided above them. The bottom end of the protective cover is connected to the bracket of the drive motor by bolts. This also ensures that the driven wheel always maintains meshing and transmission with the driving wheel, while the driven wheel itself remains stationary, only driving the transmission rod to rotate.

[0024] To further ensure the smooth movement of the collection tank 3, and while ensuring sufficient stability in rainwater collection, to maximize the amount and efficiency of rainwater collection, this invention adopts a further preferred technical solution: such as... Figure 5 As shown: The liquid collection tank 3 has a top-opening structure, and a guide structure 9 is also provided between the bottom end and the tank body 1. The guide structure 9 includes a guide post 901 and a guide groove 902; see details below. Figure 9The structure is shown. The guide post 901 is disposed on the collection tank 3, and the guide groove 902 is opened on one side of the tank body 1. The guide post 901 and the guide groove 902 are matched and installed. An infrared sensor 903 is also provided on one side of the collection tank 3, and the infrared sensor 903 maintains a signal connection with the drive motor 401, so that in the liquid collection state, the open area of ​​the collection tank 3 is 0.5-0.8 of the total area. To enhance the rainwater collection effect and optimize the design of the equipment assembly foundation, the present invention further preferably provides the following technical solution: Figure 2 As shown: The collection tank 3, driven wheel 404, and transmission rod 405 are four sets of matched and symmetrically distributed components. With this configuration, when rainwater collection is needed, the drive motor starts rotating forward, which in turn drives the driving wheel to rotate synchronously. The driving wheel meshes with the driven wheel, which in turn drives the transmission rod to rotate synchronously. The transmission rod and the collection tank are connected by a screw-nut structure; therefore, under the cooperation of the guide groove and guide post, the transmission rod will cause the collection tank to move outward, that is, extend outward. Figure 5 As shown: An infrared sensor, or alternatively an infrared displacement sensor, is installed on one side of the collection tank to monitor its movement in real time. Specifically, the initial movement distance parameters of the infrared sensor are set, and the signal is controlled by connecting a PLC controller to the drive motor. When the infrared sensor detects that the collection tank has moved to the preset position, it sends a shut-off signal to the drive motor, causing the drive motor to stop rotating forward. When rainwater collection is complete and reset is required (i.e., in non-rainy weather), the drive motor reverses, which in turn drives the collection tank to complete the reset process, ultimately achieving rainwater collection and storage and preventing losses due to water evaporation.

[0025] like Figure 2 and Figure 4As shown: In this embodiment, the collection tank 3 is further divided into a storage chamber 302 and a purified water chamber 303 by a partition 301. The volume ratio of the storage chamber to the purified water chamber is 2:1 to ensure sufficient rainwater collection, allowing for intermittent purification during dust suppression spraying. The storage chamber 302 contains a first filter screen 303, specifically located at the top of the storage chamber, secured with a clamp structure for easy disassembly, cleaning, and replacement. A purification channel 304 is formed within the partition 301, which is welded to the collection tank. The purification channel 304, from top to bottom, includes a purification filter element 305, a first liquid pump 306, and an electromagnetic switch valve 307. The first liquid pump provides strong suction, ensuring that rainwater in the storage chamber passes smoothly through the intermediate purification filter element for purification before entering the purified water chamber. The rainwater collected in the collection tank contains many impurities and may include leaf debris. To further filter and purify the collected rainwater mixture, thereby achieving a high level of cleanliness for domestic water and efficient, sustainable use of the atomizing nozzle 5, this invention adopts a preferred technical solution: a second filter screen 310 is provided at the bottom of the purification channel 304 and below the installation of the purification filter element 305; the second filter screen mainly serves to support the purification filter element, and can be fixed to the inner wall of the purification channel by welding. The mesh diameter of the second filter screen 310 is smaller than that of the first filter screen 303.

[0026] like Figure 4As shown: In a preferred embodiment, the upper part of the purification channel 304 is further provided with a retaining member 311, which includes a protrusion 312, a connecting rod 313, and a compression spring 314. The cross-section of the protrusion is a right-angled triangle, and the upper side of the protrusion 312 is a sloping structure. A retaining groove 315 is provided on one side of the purification channel 304, and the retaining groove 315 is matched and installed with the protrusion 312. A sliding groove 316 is also provided deep in the retaining groove 315. One end of the connecting rod 313 is connected to the protrusion 312, and the other end is movably disposed in the sliding groove 316. The compression spring 314 is sleeved and installed on the connecting rod 313, so that when the purification filter element 305 is installed, the protrusion 312 completes the clamping operation of the purification filter element 305. In the initial state, the protrusion is completely located in the purification channel. When the purification filter element needs to be installed, the purification filter element as a whole squeezes the protrusion, and the protrusion begins to move inward along the retaining groove. The movement of the connecting rod in the sliding groove compresses the compression spring to store energy. When the filter cartridge is pressed into place, the top of the filter cartridge misaligns with the protrusion, and the protrusion, no longer acting as an obstruction, resets under the release of the spring, thus preventing it from obstructing the filter cartridge. After a certain period of use, the operator presses the protrusion inward to remove it, thus unlocking the filter cartridge and allowing for easy removal and replacement. This method saves time and effort, avoiding the cumbersome bolt-fixing process of traditional methods. In a preferred embodiment, a disinfectant addition tube and a flocculant addition tube can be connected to the outer wall of the liquid storage chamber for appropriate disinfection or sedimentation operations.

[0027] In a preferred embodiment, to avoid excessive accumulation of impurities and silt that could affect the efficient purification operation of the purification channel, this embodiment plans to install a cleaning structure at the bottom of the liquid storage chamber. The cleaning structure includes an electric push rod and a push plate. One end of the electric push rod is fixedly installed on the side wall of the liquid storage chamber. The push plate is adapted to the width of the liquid storage chamber, and one end is connected and fixed to the electric push rod. The bottom surface of the push plate contacts the bottom surface of the liquid storage chamber. The purpose is to clean and move the mixture of impurities and silt accumulated at the bottom to one side, avoiding excessive silt near the input end of the purification channel.

[0028] like Figure 7As shown: To further enhance the rainwater filtration and purification effect, and improve the convenience of overall replacement and installation of the purification filter element 305, achieving the goal of saving time and effort and improving the rainwater purification effect, the present invention adopts a further preferred technical solution: The purification filter element 305 includes a sleeve 317, non-woven fabric 318, HEPA air filter cotton 319, sand particles 320, activated carbon particles 321, and an ultrafiltration membrane 322. The sleeve 317 has a hollow columnar structure, preferably made of 304 stainless steel, and an upgraded version can use a zirconium dioxide porous ceramic body to improve the filtration and purification effect. The ultrafiltration membrane 322 is located at the bottom of the sleeve 317, and the ultrafiltration membrane 322 has a 0.1-micron-level filter membrane structure; the bottom of the sleeve has a mesh structure, and the non-woven fabric 318 and HEPA air filter cotton 319 are arranged sequentially from top to bottom inside the sleeve 317, with the space above the non-woven fabric 318 filled with sand particles 320, wherein the particle size of the sand particles 320 is 50 microns. Activated carbon particles 321 are filled between the non-woven fabric 318 and the HEPA air filter cotton 319; 20-micron-sized sand particles 320 are filled between the HEPA air filter cotton 319 and the ultrafiltration membrane 322. With this setup, under the strong suction of the first liquid pump, the electromagnetic switch valve opens, and rainwater in the storage chamber enters the purification channel. Then, the liquid flow completes filtration through multiple filtration processes and the adsorption of impurities. By setting up the ultrafiltration membrane structure, the purpose is to improve the cleanliness of the water entering the purification chamber, thereby avoiding the problem of clogging of the atomizing nozzles due to tiny impurities. Clogging of the atomizing nozzles, coupled with continuous high pressure, can easily cause breakage at the nozzle connection, leading to safety accidents and affecting the progress of dust removal and suppression operations.

[0029] like Figure 2As shown: In this embodiment, a second liquid pump 308 is also provided in the water purification chamber 303. The second liquid pump is fixedly installed in the water purification chamber by a bracket. A liquid level sensor is also provided in the water purification chamber, and an alarm is set on the outside of the collection tank. The alarm is connected to the liquid level sensor to provide an alarm when the liquid level sensor detects a small amount of liquid in the water purification chamber. At the same time, in order to avoid drought during the non-rainy season, the liquid storage chamber can be connected to construction wastewater for recycling, or the water purification chamber can be temporarily replenished by connecting to external tap water through a replenishment pipe. The output end of the second liquid pump 308 is connected to a micron-level atomizing nozzle 5 through a delivery pipe 309. The atomizing nozzle 5 is set inside the mist cannon 2. In other words, the connection between the delivery pipe and the mist cannon is locked by a fixing clamp, thereby ensuring that the length of the delivery pipe inside the mist cannon remains unchanged. Due to the mobility of the collection tank, this invention optimizes the structural design by placing the infusion pipe at the center of the tank. The infusion pipe inside the tank (hereinafter referred to as the lower pipe) is fixedly connected to the top wall of the tank via clamps. The lower pipe is made of stainless steel and has a five-way connector at its lower end. The five-way connector consists of an upper output connector and four annularly distributed lower input connectors. The lower input connectors are connected to the second liquid pump via flexible hoses. The hoses are sufficiently long and located in the gap between the collection tank and the tank body without interference. The infusion pipe located outside the tank body between it and the fog cannon (hereinafter referred to as the upper pipe) is also made of flexible hose and is connected to the lower pipe via flange connectors. The upper pipe is also sufficiently long.

[0030] This invention optimizes the spatial structure by setting up a liquid collection tank, a liquid pump, and a purification filter element to collect rainwater or construction wastewater for dust suppression, reducing freshwater consumption and achieving the goal of saving freshwater resources. At the same time, it improves the purification and filtration effect of rainwater, avoids clogging of micron-level atomizing nozzles due to impurities, and ensures the cleanliness of the water source for wet dust suppression spraying operations. This improves the binding ability of atomized water droplets with dust, further enhancing the dust suppression effect in dusty environments such as construction sites and mines.

[0031] like Figure 2 and Figure 3 As shown: In this embodiment, a high-pressure blower 6 is also provided at the end of the mist cannon 2 furthest from the spray nozzle; a filter screen is provided on the outside of the high-pressure blower to filter impurities. The spray end of the mist cannon 2 has a conical structure; specifically, the inclination taper is 0-15 degrees. The purpose of this setting is to ensure and improve the travel distance and radiation area of ​​the mist cannon spray for dust suppression. A connecting pipe 7 is also provided between the atomizing nozzle 5 and the output end of the liquid delivery pipe 309, such as... Figure 8As shown: the connecting pipe 7 has a semi-circular structure, and multiple evenly distributed branch pipes 701 are provided on the connecting pipe 7. The branch pipes 701 are connected to the atomizing nozzles 5 through fasteners 8. A main pipe 702 is provided on one side of the connecting pipe 7, and the main pipe 702 is connected to the infusion pipe 309 through a flange seal. The purpose of this arrangement is that the pipe diameters are the same and the pressure is generally low, so the flange seal can ensure sufficient sealing effect and connection strength. In order to further ensure the efficient and sustainable operation of the atomizing nozzles 5, the atomizing nozzles 5 can be connected in parallel and used individually or in combination. Even if one atomizing nozzle 5 malfunctions, it will not cause the operation of the fog cannon to stop. It achieves the effect of having a main and a secondary nozzle, and the main and secondary nozzles can be used together. The present invention adopts a preferred technical solution: the branch pipes 701 and the atomizing nozzles 5 are three sets that are matched and evenly distributed. Furthermore, by setting up multiple atomizing nozzles with a split design and cooperating with electromagnets, along with the effective design of the connecting part, piezoelectric sensor and LED display, this fog cannon achieves the goal of zero leakage and extremely high safety while making the micron-level atomizing nozzles easy to install and monitoring the sealing surface pressure and media leakage in real time. The atomization connection of the dust suppression fog cannon of this invention is upgraded from passive response to intelligent monitoring, which effectively ensures the stability of the nozzle connection and the sealing effect.

[0032] like Figure 3 As shown: In this embodiment, the fastening component 8 includes a first electromagnet 801, a second electromagnet 802, and an adjustment structure 803. The first electromagnet 801 is located at the output end of the branch pipe 701, and the second electromagnet 802 is located at the atomizing nozzle 5. The first electromagnet 801 and the second electromagnet 802 are matched and installed, and a sealing rubber ring is provided between them to enhance the sealing effect of the connection. When the electromagnet is energized, the branch pipe and the atomizing nozzle achieve a first-level connection. The power supply of the fog cannon of this invention is specifically connected to an external power source via a wire. A PLC controller or industrial computer can be installed in the base to realize automated signal control of the motor and other structures. The circuit and control principle in this part are existing technologies and will not be described in detail. The adjustment structure 803 is used to enhance the sealing connection and monitor the pressure on the sealing surface in real time.

[0033] like Figure 3 and Figure 8As shown: To achieve the goals of convenient installation, zero leakage, extremely high safety, real-time monitoring of sealing surface pressure and media leakage for the atomizing nozzle 5, and to effectively reduce dust and suppress dust while extending its service life, this invention adopts a further preferred technical solution: The adjustment structure 803 includes a connecting part 804, a piezoelectric sensor 805, and an LED display screen 806; the connecting part 804 is a hollow structure, located at the input end of the atomizing nozzle 5, and the two are integrally formed. The piezoelectric sensor 805 is located on the end face of the connecting part 804; during rotation and downward movement, it gradually squeezes the end face of the branch pipe. The atomizing nozzle 5 is located at the center of the second electromagnet 802, and the two are connected by a thread; specifically, the connecting part of the atomizing nozzle passes through the center of the second electromagnet. The LED display screen 806 is located on the outer wall of the housing 1 and maintains a signal connection with the piezoelectric sensor 805; specifically, signal control can be achieved through a PLC controller. The connection and installation principle of the atomizing nozzle: In the initial state of connection between the first electromagnet 801 and the second electromagnet 802, the piezoelectric sensor 805 monitors a parameter value of 0. At this time, the piezoelectric sensor on the end face of the connection part is in contact with the end face of the branch pipe, without compression, so the parameter is defined as 0. However, due to the atomization effect, the pressure per unit area at the connection point of the atomizing nozzle is very high, therefore, a better and safer connection is required here. When the atomizing nozzle 5 continues to rotate downwards, under enhanced pressing conditions, the parameter value monitored by the piezoelectric sensor 805 ranges from 1 to 10. The specific design and selection can be based on a comprehensive consideration of the use of different specifications and models of atomizing nozzles and the pressure of the water flow.

[0034] like Figure 2 As shown: To improve the mobility of the fog cannon while ensuring stable operation, this invention adopts a further preferred technical solution: a base 108 is provided below the housing 1, and a caster wheel 109 and a telescopic leg 110 are provided below the base 108; the caster wheel 109 is connected to the base 108 via a bracket. The telescopic leg 110 uses a hydraulic cylinder, and one end is fixed to the base 108 by bolts.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
