Description

Technical Field

[0001] This invention relates to the field of dust suppression devices, and more particularly to an adjustable dust suppression device for urban and rural planning. Background Technology

[0002] Dustfall, also known as "falling dust," refers to airborne particulate matter that naturally falls to the ground. Its particle size is mostly 10 micrometers or larger, and the unit of measurement is the amount of material deposited on a unit area of ​​the ground surface within a certain time period. Monitoring the natural deposition of atmospheric dust is one of the earliest routine monitoring projects for air pollutants.

[0003] In existing technologies, atomized water is usually sprayed into the air to accelerate dust suppression. At this time, atmospheric dust falls to the ground along with the atomized water. If the dust that has fallen to the ground is not cleaned up in time, it will lead to a large accumulation of dust on the ground. Moreover, after the ground water vapor evaporates into the atmosphere over a long period of time, the air currents can easily cause the dust that has fallen to the ground to return to the atmosphere, resulting in a decline in the quality of dust suppression work. Summary of the Invention

[0009] Furthermore, it also includes scraper blades; several scraper blades are fixed to the telescopic support frame, and all scraper blades are in contact with the inner surface of the collection platform, and the scraper blades are symmetrically distributed about the center of the spray cannon.

[0010] Furthermore, the scraper is set at an angle.

[0011] Furthermore, the connecting cylinder is rotatably connected to the collecting platform, and the collecting platform is fixedly connected to the spray cannon; the inner cylinder is rotatably connected to the spray cannon.

[0012] Furthermore, it also includes an annular plate; the annular plate is fixedly connected to the middle of the spray cannon, and the annular plate is set in an inclined downward state.

[0016] Beneficial effects: The technical solution provided by this invention:

[0017] This invention uses a collection platform to intercept the mist sprayed into the atmosphere and the dust that comes into contact with it, preventing it from falling directly to the ground and causing a large accumulation of dust on the ground. Furthermore, it prevents the dust from being easily returned to the atmosphere by the wind after the ground water vapor evaporates over a long period of time, leading to serious re-polluting of the atmosphere. At the same time, it also prevents the atomized water from increasing the humidity in the dust-collecting area, thus avoiding the problem of increased humidity in the dust-collecting area.

[0018] This invention uses a fixed plate to move the collection platform connected to it, causing the collection platform to be stretched. The stretched part of the collection platform is then subjected to the rebound force due to its own elastic material and the return force of the spring. In this way, dust and mist that are difficult to scrape off from the inner surface of the collection platform are bounced towards the center of the collection platform, thereby achieving faster and more complete collection of mist and dust intercepted on the inner surface of the collection platform and improving work efficiency.

[0019] This invention, by setting the cross-section of the second channel to be inclined upward, when the airflow formed inside the spray cannon passes through, the inclined upward cross-section and the upward airflow form a guiding relationship, blocking the mist water that has absorbed dust from the atmosphere from falling on its surface. This avoids the mist water and dust during dust suppression from falling on the folded and stretchable parts of the flexible part surface, reducing the stains generated and facilitating subsequent manual cleaning. At the same time, it reduces the problem of dampness and easy corrosion caused by mist water accumulation over a long period of time.

[0020] This invention, by designing the cross-section of the second channel to be inclined downwards, prevents the upward airflow generated inside the spray cannon from flowing out of the second channel due to the downward-sloping cross-section creating a counterforce. This causes the atmospheric pressure airflow near the outside of the second channel to converge towards it, generating an adsorption force at the second channel that draws airflow from inside the spray cannon towards the outside. This adsorption force attracts falling mist and dust from the nearby atmosphere towards the second channel. Simultaneously, the attracted mist and dust accumulate on the surface of the annular plate and are then flung out, landing back on the inner surface of the collection platform for interception. This enhances the interception efficiency of mist and dust in the atmosphere, better enabling the reuse of mist and avoiding the problem of some mist and dust failing to be intercepted by the collection platform due to airflow interference.

Detailed Implementation

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0030] Example 1

[0031] An adjustable dust suppression device for urban and rural planning, such as Figures 1-7 As shown, the system includes a mobile water tank 1, a telescopic support frame 2, a spray cannon 3, a collection platform 4, a connecting cylinder 5, and an inner cylinder 6. The mobile water tank 1 is located below the telescopic support frame 2 and has an inlet for connecting an external water pump. The bottom of the mobile water tank 1 is equipped with four electric pulleys. The mobile water tank 1 and the telescopic support frame 2 are jointly connected to a connecting cylinder 5. The connecting cylinder 5 is equipped with a collection platform 4. The inner cylinder 6 is fixedly connected inside the connecting cylinder 5. The inner cylinder 6 is equipped with a spray cannon 3, and the spray cannon 3, the connecting cylinder 5, and the inner cylinder 6 are interconnected. The spray cannon 3 is located in the middle of the collection platform 4. There is an annular space 3d between the connecting cylinder 5 and the inner cylinder 6, and the annular space 3d is connected to the collection platform 4. A filter screen 3c is installed in the annular space 3d.

[0032] It also includes a first connecting plate 101, a motor 102, a connector 103, and a flexible component 104; the telescopic support 2 is fixedly connected to the upper part of the symmetrically distributed first connecting plates 101; each first connecting plate 101 is equipped with a motor 102; each motor 102 output shaft is fixedly connected to a connector 103; all connectors 103 are fixedly connected to a flexible component 104, and the flexible component 104 is rotatably connected to the spray cannon 3, and the flexible component 104 is made of rubber, and the bottom of the spray cannon 3 is made of rubber and is telescopically folded.

[0033] The specific workings of this invention are as follows:

[0034] Connect the water inlet on the mobile water tank 1 to the external water pump;

[0035] First, the telescopic outrigger 2 is manually retracted and secured. An external water pump is then turned on to deliver water to the mobile water tank 1. The pump inside the mobile water tank 1 delivers the water along the inner cylinder 6 to the spray cannon 3. The atomizer inside the spray cannon 3 atomizes the delivered water and sprays it out within a 1-2 meter radius of the spray cannon 3. This atomized water is then sprayed into the atmosphere, coming into contact with dust particles and accelerating dust settling. Simultaneously, the collection platform 4 intercepts the sprayed water mist and the dust particles that come into contact with it, preventing them from falling directly to the ground and accumulating large amounts of dust. Furthermore, after prolonged evaporation of ground moisture into the atmosphere, wind currents can easily cause the dust particles to return to the atmosphere, leading to severe re-polluting of the atmosphere. This also prevents the atomized water from increasing humidity in the dust-affected area.

[0036] While the spray cannon 3 continuously sprays water into the atmosphere, the collection platform 4 continuously intercepts the mist and dust falling within the spray range centered on the spray cannon 3. At the same time, the intercepted water and dust will gradually accumulate on the inner surface of the collection platform 4, and then enter the annular space 3d from the inner surface of the collection platform 4. Meanwhile, the filter screen 3c set in the annular space 3d filters the entering dust, allowing the intercepted mist to pass through the filter screen 3c to the mobile water tank 1. In this way, the mist is collected and reused to reduce the waste of water resources. At the same time, the dust falling in the air is collected to facilitate subsequent manual centralized cleaning.

[0037] At the same time, the motor 102 drives the connector 103 and the flexible part 104 to rotate clockwise and counterclockwise repeatedly to adjust the spray cannon 3 to rotate and adjust the direction of the atomized water spray.

[0038] It should be noted that the filter screen 3c is located on the outside of the inner cylinder 6. This allows the dust in the inner cylinder 6 to be filtered before the mist enters the bottom opening, thus preventing dust from entering the spray cannon 3 from the inner cylinder 6 and contaminating the spray cannon 3.

[0039] It should be noted that by using the electric pulleys installed on the mobile water tank 1 to move the whole unit at a slow speed, automated dust suppression can be achieved within the area, thus improving work efficiency.

[0040] Example 2

[0041] Based on Example 1, such as Figure 3-4 As shown, it also includes a second connecting plate 211, a fixing plate 212 and a power assembly; the telescopic support 2 is provided with a power assembly; the power assembly is provided with two second connecting plates 211; each of the two second connecting plates 211 is fixedly connected to a fixing plate 212, and each fixing plate 212 and the second connecting plate 211 are provided with a spring for the fixing plate 212 to reset.

[0042] The power assembly includes a slide rail 201 and a slider 202; the slide rail 201 is installed on the upper part of the telescopic support 2; the slide rail 201 is equipped with two sliders 202, and each slider 202 is fixedly connected to a second connecting plate 211; the slide rail 201 controls the slider 202 to drive the second connecting plate 211 to move.

[0043] It also includes a limiting wave plate 213, a spring plate 214, an impact plate 212a, and a hammer needle 214a; four limiting wave plates 213 are fixedly connected to the upper part of the telescopic support 2; each second connecting plate 211 is fixedly connected to a spring plate 214, and the spring plate 214 is slidably connected to the fixed plate 212, and a hammer needle 214a is installed on the spring plate 214, and the height of the hammer needle 214a is higher than that of the limiting wave plate 213; each fixed plate 212 is fixedly connected to the bottom of a impact plate 212a, and the tip of the hammer needle 214a is in contact with the impact plate 212a.

[0044] It also includes scraper blades 111; the telescopic support 2 is fixed with two scraper blades 111, and both scraper blades 111 are in contact with the inner surface of the collection platform 4, and the two scraper blades 111 are symmetrically distributed about the center of the spray cannon 3.

[0045] The scraper 111 is set at an angle. When the power component drives the second connecting plate 211, the fixing plate 212 and the collection platform 4 to rotate, the scraper 111 is set at an angle so that the dust and mist scraped off in contact with the collection platform 4 can be gathered towards the center of the collection platform 4.

[0046] The connecting cylinder 5 is rotatably connected to the collecting platform 4, and the collecting platform 4 is fixedly connected to the spray cannon 3; the inner cylinder 6 is rotatably connected to the spray cannon 3; when the power component drives the second connecting plate 211 and the fixed plate 212 to move, it also drives the collecting platform 4 and the spray cannon 3 to rotate, thus increasing the direction in which the spray cannon 3 can spray atomized water and improving the applicability of the equipment.

[0047] The specific workings of this invention are as follows:

[0048] As the spray cannon 3 continuously sprays water into the atmosphere and the collection platform 4 continuously intercepts the falling mist and dust within a 1-2 meter spray range centered on the spray cannon 3, more and more dust and mist accumulate on the inner surface of the collection platform 4. At this point, relying solely on gravity to allow the accumulated mist and dust to enter the mobile water tank 1 is ineffective and cannot collect them completely. Therefore, the power component drives the second connecting plate 211, the fixed plate 212, the spring plate 214, the collection platform 4, and the spray cannon 3 to move, causing the collection platform 4 and the spray cannon 3 to move in a certain direction. In a clockwise rotation state, the collecting platform 4, which is also rotating clockwise, continuously contacts the scraper 111. This allows the scraper 111 to collect the mist and dust on the inner surface of the collecting platform 4 to one side during the continuous contact. At the same time, because the scraper 111 is angled, the dust and mist scraped off by contact with the collecting platform 4 can be concentrated towards the center of the collecting platform 4, thereby accelerating the collection efficiency of mist and dust. Meanwhile, the clockwise rotation of the spray cannon 3 further increases the direction of atomized water spray, improving the applicability of the equipment.

[0049] Meanwhile, because the scraper 111 has limited effect on removing mist and dust from the inner surface of the collection platform 4, some mist and stubborn dust will remain on the inner surface of the collection platform 4. Therefore, as the spring plate 214 is driven, it continuously contacts the surface of the limiting wave plate 213. Under the action of the limiting wave plate 213, the tapping needle 214a on the spring plate 214 is repeatedly pushed away from the center of the collection platform 4. Then, due to the spring rebound force on the spring plate 214, it is reset. During this process, the tapping needle 214a repeatedly taps the impact plate 212a. After the impact plate 212a is tapped, the fixed plate 212 and the collection platform 4 vibrate. In this way, as the collection platform 4 is rotating, it is repeatedly tapped and vibrates, which vibrates the dust and mist that are difficult to scrape off from the inner surface of the collection platform 4 towards the center of the collection platform 4. This achieves faster and more complete collection of mist and dust intercepted on the inner surface of the collection platform 4, improving work efficiency.

[0050] Example 3

[0051] Based on Example 2, such as Figure 5-7As shown, it also includes an annular plate 301; the annular plate 301 is fixedly connected to the middle of the spray cannon 3, and the annular plate 301 is set in an inclined downward state.

[0052] A second through groove 3b is provided in the middle of the spray cannon 3, and the second through groove 3b is located on the upper part of the annular plate 301. The cross-section of the second through groove 3b is inclined downward. When the atomized water inside the spray cannon 3 is sprayed upward, the airflow formed in the spray cannon 3 is prevented from flowing out smoothly from the second through groove 3b because the cross-section of the second through groove 3b is inclined downward.

[0053] The upper part of the spray cannon 3 is provided with a first through groove 3a, and the cross-section of the first through groove 3a is inclined upward, and the first through groove 3a is located above the flexible member 104; when the atomized water inside the spray cannon 3 is sprayed upward, the airflow formed in the spray cannon 3, at this time the cross-section of the second through groove 3b is inclined upward so that the airflow can flow out smoothly from the second through groove 3b.

[0054] It also includes a breathable membrane 302; the breathable membrane 302 is provided in the middle of the spray cannon 3, and the breathable membrane 302 is located on the side of the second through groove 3b near the outer wall of the spray cannon 3.

[0055] The specific workings of this invention are as follows:

[0056] As the spray cannon 3 continuously sprays water into the atmosphere, the sprayed water mist constantly absorbs dust from the atmosphere and falls rapidly. At this time, the surface of the flexible component 104 needs to adapt to the compression deformation caused by the rotation of the spray cannon 3, so the surface of the flexible component 104 is folded and expandable. When the water mist that has absorbed dust from the atmosphere falls onto it, dust and water will accumulate at the folded and expandable points on the surface of the flexible component 104, making the equipment difficult to clean subsequently. Furthermore, the accumulated dust and water can easily accelerate corrosion and damage to the surface of the flexible component 104 after a long period of accumulation. Therefore, the cross-section of the first through groove 3a is inclined upwards, and simultaneously during the spray... When the upward airflow formed inside the barrel 3 passes through, the upward-sloping cross-section forms a guiding relationship with the upward airflow, allowing the airflow to flow smoothly out from the second channel 3b. At the same time, the first channel 3a is located above the flexible member 104, and the airflow blown out from the second channel 3b forms an air curtain above the flexible member 104 to block the mist that has absorbed dust from the atmosphere from falling on its surface. This prevents the mist and dust from falling on the folded and retractable parts of the flexible member 104 during dust settling, reducing the stains generated and facilitating subsequent manual cleaning. It also reduces the problem of moisture and long-term corrosion caused by the accumulation of mist.

[0057] Meanwhile, because the spray particles produced by the spray cannon 3 are extremely small and lightweight, they are easily affected by airflow after adsorbing dust particles of various sizes in the air, causing their landing trajectory to deviate. This results in a large amount of mist and dust falling onto the outer ring of the collection platform 4, thus reducing the collection efficiency of the collection platform 4. Furthermore, when the collection platform 4 and the spray cannon 3 rotate clockwise, windflow will be generated around the collection platform 4 and the spray cannon 3, interfering with the mist and dust falling into the atmosphere and preventing them from being collected by the collection platform 4. Therefore, by setting the cross-section of the second channel 3b to be inclined downwards, and simultaneously, when the upward airflow generated inside the spray cannon 3 passes through, the inclined downward cross-section creates a counterforce against the upward airflow, preventing the airflow from flowing out of the second channel 3b. Consequently, when the airflow generated inside the spray cannon 3 passes through the second channel 3b near the inside of the spray cannon 3, the localized wind pressure generated by the airflow not flowing out of the second channel 3b results in a decrease in pressure inside the spray cannon 3 near the second channel 3b. This causes the atmospheric pressure airflow near the outside of the second channel 3b to converge towards the second channel 3b, creating an adsorption force at the second channel 3b that draws airflow from inside the spray cannon 3 to the outside. This adsorption force can attract the mist and dust falling in the atmosphere near the second channel 3b, making it easier for the mist and dust to accumulate in the central area of ​​the collection platform 4. This avoids a large amount of mist and dust being intercepted near the outer edge of the collection platform 4, which would reduce collection efficiency. At the same time, the breathable membrane 302 further facilitates the collection of mist and dust. The system intercepts mist and dust in one step, preventing them from entering the spray cannon 3 and causing pollution inside. The intercepted mist and dust accumulate on the surface of the annular plate 301. The annular plate 301, which is rotated by the spray cannon 3, generates centrifugal force on the mist and dust on its surface, throwing them away from the spray cannon 3. The thrown-out mist and dust then fall back onto the inner surface of the collection platform 4, thus enhancing the interception efficiency of mist and dust in the atmosphere and better achieving the reuse of mist.

[0058] It also includes a breathable membrane 302; the breathable membrane 302 is provided in the middle of the spray cannon 3, and the breathable membrane 302 is located on the side of the second through groove 3b near the outer wall of the spray cannon 3.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
