Description

Technical Field

[0001] This utility model relates to the technical field of atomizing dust suppression devices, and more specifically to an anti-clogging atomizing dust suppression device. Background Technology

[0002] Because construction sites generate a lot of dust, sprinkler systems are often installed on the site fences to suppress dust with water mist. A sprinkler system consists of a main unit, water tank, multi-stage pump, spray pipes, and nozzles. The principle is that tap water enters the system, is filtered through a micron-level precision water filter, and then sent to the built-in automatic water supply tank. It is then output through high-pressure pipes to high-pressure nozzles, spraying micron-sized fine water mist particles that cover the area around the fence, adhering to the dust and causing it to settle due to weight, thus achieving dust suppression. The principle is based on the fact that the microparticles produced by the spray, due to their extremely small size and essentially zero surface tension, can quickly adsorb dust particles of various sizes in the air, effectively controlling dust, especially in large, open areas.

[0003] According to announcement number CN217490279U, announcement date: September 27, 2022, a dust suppression device for fencing mist spraying is disclosed, including a main unit, a spray pipe, multiple nozzle bodies, nozzles, and two heat dissipation windows. The spray pipe is located on one side of the main unit, and the multiple nozzle bodies are equidistantly arranged on the spray pipe. The nozzles are located on the top of the nozzle bodies, and the two heat dissipation windows are symmetrically arranged on both sides of the main unit. A fixing ring is fixed to the surface of the nozzle, and an annular groove is formed on the surface of the fixing ring. Through the design of the fixing ring, annular groove, fixing block, first metal rod, arc block, sliding hole, second metal rod, and first limiting groove, the stability of the connection between the nozzle body and the nozzle can be improved, and the nozzle can be prevented from rotating due to impact from external objects, which would cause the connection between the two to loosen and affect the use effect of the device. Moreover, this structure is simple to operate and convenient to use.

[0004] In the prior art, including the aforementioned patent, a mist spray is used to achieve the effect of dust removal. However, because the nozzle orifice is small, after a long period of use, the nozzle orifice is easily blocked by the accumulation and adhesion of scale or dust. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging atomizing dust suppression device to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging atomizing dust suppression device, comprising a mounting base and an injection pipe disposed thereon, nozzles symmetrically arranged on the mounting base, a movable base coaxially arranged on the mounting base, a flexible nozzle and a sealing flap disposed on the movable base, the injection pipe being connected to the nozzles through the mounting base and the flexible nozzles, a cleaning spray channel being opened on the movable base with its end facing the nozzle's spray hole, and the sealing flap being used to separate the flexible nozzle and the cleaning spray channel.

[0007] Preferably, the movable seat is vertically slidably arranged on the mounting base, and the movable seat is provided with a receiving cavity. The movable seat is slid to a low position so that the nozzle is located in the receiving cavity.

[0008] Preferably, a rotating seat is rotatably provided inside the mounting base, and flexible protrusions are arranged in a circumferential array on the rotating seat. Overlapping grooves are provided on the flexible protrusions. An extension hook is provided on the nozzle. The movable seat slides from a high position to a low position to make the flexible nozzle push the rotating seat to rotate. Several flexible protrusions are successively overlapped with the extension hook through the overlap grooves and then deformed and detached.

[0009] Preferably, the movable seat is provided with a movable plate, the movable plate is slidably disposed in the movable cavity of the mounting seat, and the movable seat is provided with a flow valve that separates the sealing flap and the flexible nozzle from the movable cavity. The movable seat slides from a high position to a low position to reduce the volume of the internal chamber of the movable cavity.

[0010] Preferably, the mounting base is provided with a drive gear and a drive motor, and the movable base is symmetrically arranged with sliding parts. The drive gear is fixedly connected to the output end of the drive motor, and the drive gear is coupled with the straight tooth groove opened on the sliding part.

[0011] Preferably, the movable seat is provided with a scraping ring, and the movable seat is driven to slide from a high position to a low position so that the scraping ring moves to scrape the nozzle surface of the nozzle.

[0012] In the above technical solution, the anti-clogging atomizing dust suppression device provided by this utility model has the following beneficial effects: Utilizing the movable seat and sealing flap, when the nozzle orifice is gradually blocked by scale or dust accumulation, the water pressure inside the movable seat gradually increases due to the blockage, which in turn causes the sealing flap to deform and open. At this time, the water inside the movable seat is sprayed along the cleaning spray channel to the surface of the nozzle orifice for impact, thereby cleaning and unblocking the blocked nozzle by reverse impact, avoiding the problem of poor spraying effect caused by scale or dust accumulation in the nozzle, and improving the use effect of the nozzle.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0021] like Figure 1-4 As shown, an anti-clogging atomizing dust suppression device includes a mounting base 1 and an injection pipe 9 disposed thereon. Spray heads 2 are symmetrically arranged on the mounting base 1, and a movable base 3 is coaxially arranged on the mounting base 1. A flexible spray head 31 and a sealing flap 81 are disposed on the movable base 3. The injection pipe 9 is connected to the spray head 2 through the mounting base 1 and the flexible spray head 31. A cleaning spray channel 32 is opened on the movable base 3 with its end facing the spray hole of the spray head 2. The sealing flap 81 is used to separate the flexible spray head 31 and the cleaning spray channel 32.

[0022] Specifically, such as Figure 2 As shown, the injection pipe 9 is connected to the flexible nozzle 31 through the interior of the mounting base 1 and the movable base 3. The flexible nozzle 31 is in contact with the contact groove 21 of the nozzle 2 to communicate with each other. When spraying is required, water is sprayed out along the mounting base 1, the movable base 3, the flexible nozzle 31 and the nozzle 2 to perform mist spraying. If the nozzle orifice of the nozzle 2 is gradually blocked by scale or dust, the water pressure inside the movable base 3 will gradually increase due to the blockage. This water pressure will cause the sealing flap 81 to deform and open. At this time, the water in the movable base 3 will spray out along the cleaning spray channel 32 to the surface of the nozzle orifice of the nozzle 2 to impact it, thereby cleaning and unblocking the blocked nozzle 2 by reverse impact. This avoids the problem of poor spraying effect caused by scale or dust accumulation in the nozzle 2, and improves the use effect of the nozzle 2.

[0023] In the above technical solution, by utilizing the movable seat 3 and the sealing flap 81, when the nozzle of the spray head 2 is gradually blocked by scale or dust, the water pressure inside the movable seat 3 gradually increases due to the blockage. This water pressure causes the sealing flap 81 to deform and open. At this time, the water inside the movable seat 3 is sprayed along the cleaning spray channel 32 onto the surface of the nozzle of the spray head 2 to impact it, thereby cleaning and unblocking the blocked nozzle 2 by reverse impact. This avoids the problem of poor spraying effect caused by scale or dust accumulation in the nozzle 2, and improves the performance of the nozzle 2.

[0024] As a further embodiment provided by this utility model, the movable seat 3 is vertically slidably arranged on the mounting base 1, and the movable seat 3 is provided with a receiving cavity 33. The movable seat 3 is slid to a low position so that the nozzle 2 is located in the receiving cavity 33.

[0025] Specifically, such as Figure 2 As shown, the movable seat 3 is vertically slidably arranged on the mounting base 1. At this time, the movable seat 3 is in a high position so that it does not cover the nozzle 2, allowing the nozzle 2 to perform normal spraying operations. When spraying is not required, the movable seat 3 can be driven to slide vertically from the high position to the low position. In this case, the movable seat 3 slides to place the nozzle 2 within the receiving cavity 33, providing protection and further enhancing the protection of the nozzle 2, preventing dust from clogging it when not in use. When the movable seat 3 slides to the low position, the flexible nozzle 31 can also deform and move away from the contact groove 21 of the nozzle 2.

[0026] As a further embodiment of this utility model, a rotating seat 4 is rotatably provided inside the mounting base 1. Flexible protrusions 5 are arranged in a circular array on the rotating seat 4. Overlapping grooves 51 are provided on the flexible protrusions 5. An extension hook 22 is provided on the nozzle 2. The movable seat 3 slides from a high position to a low position so that the flexible nozzle 31 pushes the rotating seat 4 to rotate. Several flexible protrusions 5 are successively overlapped on the extension hook 22 through the overlap grooves 51 and then deformed and detached.

[0027] Specifically, such as Figure 4 As shown, a contact groove 41 is provided on the rotating seat 4. After the nozzle 2 completes the spraying operation, it can drive the movable seat 3 to slide from the high position to the low position to cover and protect the nozzle 2. At the same time, the flexible nozzle 31 slides down vertically. The flexible nozzle 31 abuts against the contact groove 41 and pushes the rotating seat 4 to rotate. Moreover, several flexible protrusions 5 are successively connected to the extension hook 22 through the overlapping groove 51 and then deformed and detached. This causes the extension hook 22 on the nozzle 2 to vibrate due to the contact deformation and detachment of the flexible protrusions 5, thereby shaking off the droplets in the nozzle 2's spray hole. This prevents the droplets from drying in the nozzle 2's spray hole and forming scale blockage, thus improving the service life of the nozzle 2.

[0028] As a further embodiment of this utility model, the movable seat 3 is provided with a movable plate 34, the movable plate 34 is piston-slidably disposed in the movable cavity 11 of the mounting seat 1, and the movable seat 3 is provided with a flow valve 82 that separates the sealing flap 81 and the flexible nozzle 31 from the movable cavity 11. The movable seat 3 slides from the high position to the low position to reduce the internal chamber volume of the movable cavity 11.

[0029] Specifically, such as Figure 2 As shown, the movable plate 34 is piston-slidably disposed in the movable cavity 11 of the mounting base 1. After the spraying operation of the nozzle 2 is completed, the flow valve 82 is closed, which allows the movable base 3 to slide from the high position to the low position to cover the nozzle 2 in the receiving cavity 33. At this time, the piston of the movable plate 34 slides to reduce the internal chamber volume of the movable cavity 11. At this time, the liquid pressure in the movable base 3 increases due to the decrease in the internal chamber volume of the movable cavity 11. Then, the flow valve 82 can be opened and then quickly closed. The high pressure liquid in the movable base 3 can push the sealing flap 81 to deform and open. Then, the liquid is sprayed along the cleaning spray channel 32 to the peripheral side of the mounting base 1 for cleaning, thereby washing off the dust or debris adhering to the peripheral side of the mounting base 1, and cleaning the surface of the mounting base 1.

[0030] As a further embodiment of this utility model, the mounting base 1 is provided with a drive gear 71 and a drive motor 72, and the movable base 3 is symmetrically arranged with sliding parts 35. The drive gear 71 is fixedly connected to the output end of the drive motor 72, and the drive gear 71 is coupled with the straight tooth groove opened on the sliding part 35.

[0031] Specifically, such as Figure 3As shown, the movable seat 3 is vertically slidably arranged on the mounting base 1 by means of symmetrically arranged sliding parts 35 to improve the sliding stability of the movable seat 3. The drive gear 71 is rotatably disposed in the mounting base 1, and the drive motor 72 can drive the movable seat 3 to slide vertically through the drive gear 71, thereby further improving the sliding stability of the movable seat 3.

[0032] As a further embodiment of this utility model, a scraping ring 6 is provided on the movable seat 3. The movable seat 3 is driven to slide from a high position to a low position so that the scraping ring 6 moves to scrape the surface of the nozzle 2.

[0033] Specifically, such as Figure 2 As shown, the movable seat 3 is provided with a scraping ring 6. When the movable seat 3 is driven to slide from a high position to a low position, the scraping ring 6 moves to scrape the surface of the nozzle 2. Thus, the scraping ring 6 directly scrapes the surface of the nozzle 2 to scrape and clean hard debris on the nozzle, thereby further improving the cleaning effect of the nozzle 2 and reducing the clogging problem of the nozzle 2.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
