Description

Technical Field

[0001] The invention relates to the technical field of spraying dust reduction, and in particular to a novel intelligent spraying dust reduction method. Background Art

[0002] Spray dust reduction technology disperses water into fine droplets and sprays them toward the dust source to suppress and capture dust. These water mist particles can quickly absorb dust particles in the air to form an effective dust control effect. It is suitable for dust control and reduction in large open areas, such as outdoor construction sites, both sides of construction roads, indoor foundries, textile mills, and food factories.

[0003] At present, the main working mode of outdoor open-air spray dust removal is to start the spray system and then open all the nozzles to spray. Although this spray dust reduction system can ensure the dust reduction effect, when the wind speed is high in the open air, the dust will float to one side with the wind direction. Therefore, when the nozzles in four directions are all opened to spray, not only the dust reduction effect of the sprinkler heads located above the wind direction is poor, but the large amount of water will also cause unnecessary waste of water resources.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 7The present invention provides a technical solution: a new intelligent spray dust reduction method, comprising:

[0035] The spray area is set up, and the spray parts are connected in parallel through pipelines 4 according to the range of the material dust generating area, so that they surround the material dust generating area and form a central spray area, and the spray direction of the spray parts is toward the central spray area. The connection between each spray part and the pipeline 4 is provided with a solenoid valve 5 for controlling the switch of the spray part;

[0036] A wind direction and anemometer 1 and a moisture sensor 3 for collecting information. The wind direction and wind speed information of the material dust-generating area is obtained through the wind direction and anemometer 1, and the moisture sensor 3 is used to obtain the moisture content information of the material in the material dust-generating area;

[0037] The PLC controller 2 used for regulation is used to collect and capture the information obtained by the wind direction and anemometer 1 and the moisture content sensor 3, and control the liquid spraying part at the windward position upwind to close and the liquid spraying part at the windward position downwind to open according to the information collected by the wind direction and anemometer 1. At the same time, the water pressure in the liquid spraying part is controlled according to the information obtained by the moisture content sensor 3, and the water pressure is inversely proportional to the moisture content obtained by the moisture content sensor 3.

[0038] At present, when spraying dust removal is carried out in an open-air venue, since the open-air environment is affected by wind speed, the dust or powder raised in the dust-raising area of ​​the material will float with the wind direction. In this case, there is no need to fully open the nozzles on all sides, and only the nozzles on the side opposite to the wind direction need to be opened. For example, when the wind direction is northwest, the dust will float to the southeast side. At this time, under the information collection of the wind direction and anemometer 1, the PLC controller 2 will open the nozzles on the east and south sides, and then control the water pressure in the spray part according to the information obtained by the moisture content sensor 3 (the higher the moisture content, the less dust is raised by the material). When the moisture content is high, the water pressure is lowered, so that the amount of water mist sprayed by the spray parts opened on the east and south sides is less. On the contrary, the water pressure is increased to increase the amount of water mist sprayed.

[0039] In this way, the position and spray volume of the spray part can be intelligently selected according to the wind direction and the moisture content of the material. There is no need to open all the spray parts around. A better dust reduction effect can be achieved with relatively small amount of water, solving the problem of water resource waste and achieving energy-saving and environmental protection effects.

[0040] In one of the more preferred embodiments, when the wind direction and anemometer 1 detects that the wind speed exceeds a preset value, the PLC controller 2 controls the spray part at the position above the wind direction to open briefly, and adjusts the direction of the spray part at this position to spray toward the position above the wind direction, until the wind direction and anemometer 1 detects that the wind speed is lower than the preset value, the PLC controller 2 closes the spray part at the position above the wind direction again and resets the steering adjustment.

[0041] In actual use, due to the variable wind speed in an open-air environment, the water mist sprayed from the liquid spraying part needs to combine with the dust raised in the material dust-generating area to achieve the purpose of dust reduction. However, when the wind speed is high, both the raised dust area and the sprayed water mist area will move with the flow of air, which will cause the dust reduction area formed by the combination of the dust area and the water mist area to be greatly offset from the material dust-generating area. If this offset phenomenon occurs in an urban area or when there are other buildings around, the sewage beads formed by the combination of water mist and dust will fall in other areas, thereby polluting the surrounding environment.

[0042] Therefore, the best area for dust reduction is to make the combination of water mist and dust fall back to the material dust-generating area as much as possible. On the one hand, it can increase the moisture content of the material dust-generating area and reduce the amount of dust. On the other hand, it can also reduce the impact on the surrounding environment.

[0043] Therefore, when the wind direction and speed meter 1 detects that the wind speed exceeds the preset value, the PLC controller 2 will control the liquid spraying part at the position above the wind direction to open, and adjust the direction of the liquid spraying part at this position to spray toward the position above the wind direction, that is, if it is northwest wind, it can be known from the above content that the liquid spraying parts on the east and south sides are in the open state at this time, then the liquid spraying parts on the west and north sides are also opened at this time, and the direction of their spraying is to spray toward the position above the wind direction, that is, spraying against the wind, so that the sprayed water mist area will enter the material dust-generating area with the wind, so as to achieve the purpose of arranging the water mist area in advance, so that the water mist area and the dust area can complete the combination of water mist and dust in advance during the movement, so that the combination of the two can fall back into the material dust-generating area as much as possible, so as to limit the deviation of the dust reduction area, thereby achieving the effect of protecting the surrounding environment;

[0044] Moreover, since the water mist areas arranged on the northwest sides will enter the material dust-generating area in advance, the water mist areas arranged on the southeast sides can also serve as the second barrier. With the early intervention of the first water mist area, the water mist areas on the southeast sides can provide better interception of the remaining dust, further limiting the deviation of the dust reduction area.

[0045] In one of the more preferred embodiments, the liquid spraying part includes a bracket 7, a rotating column 8 is rotatably mounted on the top of the bracket 7, a swing rod 11 is rotatably mounted on the top of the rotating column 8, a water spray head 6 connected to the pipeline 4 is mounted on one end of the swing rod 11, a bearing plate 9 is fixed to the outer wall of the rotating column 8, a hole is opened on the top of the bearing plate 9, and a lifting rod 10 is vertically slidably mounted in the hole, and the top of the lifting rod 10 is rotatably connected to one end of the swing rod 11 through a slide groove slide rod structure;

[0046] It also includes a switching part, which is electrically connected to the PLC controller 2. The PLC controller 2 controls the rotation and switching of the rotating column 8 through the switching part, and when switching, the swing rod 11 rotates and drives the sprinkler head 6 to spray obliquely upward.

[0047] For details of the spraying part, please refer to Figure 2 and Figure 5 The bracket 7 can be connected to the external structure for installing the overall structure and directing the water spray head 6 toward the material dust-generating area. When adjustment is required, the switching part will control the rotation of the rotating column 8 to rotate, thereby changing the direction of the water spray head 6. At the same time, the rotation of the swing rod 11 can also make the water spray head 6 spray obliquely upward to expand its spraying range. When the wind speed is high, the height of the dust raised in the material dust-generating area will also increase. Therefore, the rotation adjustment of the water spray head 6 can make the water mist area also increase to ensure the subsequent dust reduction effect.

[0048] The slideway and slide bar structure can be found in Figure 2 The purpose is to allow the connection between the lifting rod 10 and the swing rod 11 to have sufficient offset to avoid disconnection of the connection between the two.

[0049] Embodiment 1:

[0050] Based on the above embodiment, an implementation method of a switching component is provided. For details, please refer to Figure 2-4 ;

[0051] The switching part includes a sliding plate 12 slidably mounted on the outer wall of the rotating column 8 and located below the bearing plate 9, the bottom end of the lifting rod 10 is fixed on the sliding plate 12, an inner liner 13 sleeved on the outer wall of the rotating column 8 is fixed to the bottom of the bearing plate 9, an outer sleeve 14 sleeved on the outer wall of the inner liner 13 is fixed to the top of the sliding plate 12, and the inner liner 13, the outer sleeve 14 and the outer wall of the rotating column 8 together form a sealed cavity, and a micro air pump for injecting or extracting air into the sealed cavity is installed on the outer wall of the bearing plate 9, and the micro air pump is connected to the PLC controller 2 signal;

[0052] A plug 17 sleeved on the outer wall of the rotating column 8 is fixed to the bottom of the sliding plate 12, a fixed tube 15 sleeved on the outer wall of the plug 17 is fixed to the top of the bracket 7, and a first spring 16 sleeved on the outer periphery of the plug 17 is connected between the fixed tube 15 and the sliding plate 12, a spiral groove 18 is opened on the inner wall of the fixed tube 15, and a limit contact block 19 slidably installed in the spiral groove 18 is fixed to the outer wall of the plug 17.

[0053] The inner walls of the spiral groove 18 at the ends of the notches on both sides are installed with first contact pieces 26, and the outer wall of the limit contact block 19 is installed with a first contact point 25 that can contact the power connection piece. When the first contact point 25 contacts one of the first contact pieces 26, the corresponding solenoid valve 5 is in an open state, and when the two are separated, the corresponding solenoid valve 5 is in a closed state.

[0054] When switching, the micro air pump will be controlled by the PLC controller 2 and inject air into the sealed cavity. Under the action of the internal air pressure, the outer sleeve 14 and the sliding plate 12 will slide downward, and at the same time drive the fixed tube 15 to move downward. Under the sliding cooperation between the limit contact block 19 and the spiral groove 18, the fixed tube 15 will move downward and rotate at the same time, thereby driving the sliding plate 12, the lifting rod 10, the rotating column 8 and the swing rod 11 above to rotate together, thereby achieving the purpose of rotating and adjusting the water spray head 6;

[0055] Moreover, when the sliding plate 12 moves downward together with the fixed pipe 15, it drives the lifting rod 10 to drive the swing rod 11 to swing, so that the sprinkler head 6 can be adjusted upward while being rotated;

[0056] On the contrary, during resetting, the micro air pump will control the PLC controller 2 to extract the air in the sealed cavity, and realize the resetting process under the action of the negative pressure inside it. Moreover, due to the setting of the first spring 16, the first spring 16 will accumulate a certain torsional force while the above-mentioned sliding plate 12 moves downward and rotates. The torsional force can provide auxiliary force for the resetting rotation of the sliding plate 12 during resetting, so as to make its resetting smoother, and also provide a certain support effect for the sliding plate 12 in the resetting state.

[0057] The setting of the first contact 25 in the spiral groove 18 and the first contact pieces 26 on both sides of the groove can ensure that the solenoid valve 5 can still be in a connected state after the water spray head 6 is switched to keep the solenoid valve 5 open. In further implementation, the switching of the two first contact pieces 26 can be used to control the opening degree of the solenoid valve 5. It can be seen from the above content that the switching of the water spray head 6 is under the state that the wind speed exceeds the preset value. Therefore, by setting the opening degree of the solenoid valve 5 that can be controlled by setting the two first contact pieces 26, the first contact 25 can increase the opening degree of the solenoid valve 5 when it contacts the first contact piece 26 below, thereby increasing the spray amount of the water spray head 6, that is, increasing the water pressure, thereby increasing the water mist area created by the windward spraying, thereby increasing the dust reduction intensity, and further reducing the deviation of the dust reduction area.

[0058] Embodiment 2:

[0059] Based on the above embodiment, a second implementation of the switching component is provided. Figure 5-7 ;

[0060] The switching part includes a fixing plate 20 fixed to the outer wall of the rotating column 8 and located below the bearing plate 9, a cylindrical cam 21 is fixed to the top of the bracket 7, a hole is opened on the top of the fixing plate 20, and the bottom end of the lifting rod 10 passes through the hole and contacts and abuts against the top arc surface of the cylindrical cam 21, a connecting pipe 22 sleeved on the outer periphery of the lifting rod 10 is fixed between the bearing plate 9 and the fixing plate 20, a retaining ring 23 is fixed to the outer wall of the lifting rod 10 located in the connecting pipe 22, and a second spring 24 is installed between the retaining ring 23 and the bearing plate 9;

[0061] The switching unit also includes a micro motor for driving the rotating column 8 to rotate and adjust, and the micro motor is connected to the PLC controller 2 by signal.

[0062] Two second contact pieces 28 are installed on the inner wall of the connecting pipe 22, and second contacts 27 that can contact the second contact pieces 28 are installed on the outer wall of the retaining ring 23. When the second contact 27 contacts one of the second contact pieces 28, the corresponding solenoid valve 5 is in an open state.

[0063] When switching, the PLC controller 2 controls the micro motor to drive the rotating column 8 to rotate, so that the fixed plate 20, the bearing plate 9, the lifting rod 10 and the swing rod 11 rotate together, thereby achieving the purpose of adjusting the water spray head 6;

[0064] During the rotation of the lifting rod 10, under the elastic force of the second spring 24, the lifting rod 10 will move downward, driving the swing rod 11 to swing to adjust the elevation angle of the water sprinkler 6. At the same time, the bottom end of the lifting rod 10 will slide along the top arc surface of the cylindrical cam 21, thereby completing the purpose of switching and adjusting the elevation of the water sprinkler 6.

[0065] On the contrary, when resetting, the PLC controller 2 will control the micro motor to drive the rotating column 8 to rotate in the opposite direction, the lifting rod 10 will slide back to the highest point of the cylindrical cam 21, and the swing rod 11 and the sprinkler head 6 will also complete the reset;

[0066] Furthermore, when the retaining ring 23 is lifted and lowered, the second contact point 27 will also switch between the two second contact pieces 28, thereby achieving the effect of the first embodiment, which will not be described in detail.

[0067] In one of the more preferred embodiments, the swing arm 11 is in a horizontal state in the initial state, and when the swing arm 11 rotates upward, the angle between the swing arm 11 and the horizontal line is 30-60 degrees.

[0068] In the horizontal state, the spraying range of the swing rod 11 will be relatively more uniform, and the falling time of water mist and dust will be shorter. When the swing rod 11 rotates upward, when the angle between it and the horizontal is 30-60 degrees, the spraying range is larger, and 45 degrees is preferred.

[0069] In one of the more preferred embodiments, the liquid spraying part adopts an electric spray head, and the spraying range is adjusted inversely proportional to the change of the angle between the electric spray head and the horizontal line.

[0070] The liquid spraying part can also adopt an electric nozzle, such as the electric nozzle currently available on the market. Since the higher the height, the greater the wind speed, it can be known from the previous content that the purpose of the nozzle spraying upward is to expand the range of the water mist area in an environment with a higher wind speed. However, if the spraying range of the nozzle is larger, the droplets sprayed will decrease accordingly. Therefore, there is a possibility that the sprayed water mist is directly blown away by the wind. Therefore, the spraying range is automatically adjusted by adopting an electric nozzle. Because the reduction in range means that the droplets will increase, the height at which it can be sprayed will also increase accordingly. Therefore, it can create a sufficient water mist area in an environment with a higher wind speed. In this way, the adjustment of its range is controlled by the change in the angle during the pitch adjustment. When the angle between it and the horizontal line increases, the spraying range of the electric nozzle will decrease. Conversely, when the angle between it and the horizontal line decreases, the spraying range will increase. The specific control circuit and other methods can be easily implemented by those skilled in the art, so they will not be repeated here.

[0071] In one of the more preferred embodiments, the PLC controller 2 also controls the number of liquid spraying parts opened at the corresponding position according to the information of the water content, and the water content is inversely proportional to the number of liquid spraying parts opened.

[0072] Similarly, the information on the moisture content of the material can also be used to intelligently select the number of liquid spray units to be opened, so as to achieve a better dust reduction effect with relatively less water consumption. Among them, the spray switches of the liquid spray units are distributed at intervals, which can also keep the water mist area relatively uniform.

[0073] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0074] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
