Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology in construction engineering, and in particular to a dust suppression device for construction projects. Background Technology

[0002] Construction projects involve civil engineering work, which generates a lot of dust at the construction site. In dry weather or regions, fine soil on the ground splashes when it collides with objects, causing fine soil and dust to fly into the air. This is especially noticeable when vehicles pass by, with a large amount of fine soil and dust floating in the air. In severe cases, this can even affect visibility and seriously affect the health of workers. Therefore, dust suppression devices are usually used at construction sites to quickly bring dust to the ground, thereby reducing the amount of fine soil and dust in the air.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Existing dust suppression devices lack a water source filtration device. During use, impurities carried in the raw water will enter the atomizing nozzle with the water flow. When these impurities are sprayed out through the nozzle, they can easily cause blockage of the internal channels of the nozzle. This blockage not only directly affects the atomization effect of the nozzle, but in severe cases, it can even completely block the water flow, thereby significantly reducing or even completely losing the dust suppression function, seriously affecting the normal operation and use effect of the device. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing dust suppression devices lack a water filtration device. Therefore, we propose a construction dust suppression device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a construction dust suppression device, comprising a mobile cart: a water tank is installed at one end of the top of the mobile cart, and a spray dust suppression device is installed at the other end of the top of the mobile cart. A filter box is provided at the bottom of the spray dust suppression device, the bottom of the filter box is fixed to the top of the mobile cart, a cover is installed on the top of the filter box, three mounting slots are fixed on both sides inside the filter box, a connecting plate is provided at the top of the filter box, three mounting frames are fixed at the bottom of the connecting plate, the three mounting frames are slidably connected to the mounting slots, filter plates are installed inside the three mounting frames, a handle is fixed on the top of the cover, and fixing components are installed at both ends of the top of the cover.

[0011] Preferably, a third soft pad is installed on the top of the sealing strip.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, the mounting frame is aligned with the mounting groove and installed into the interior of the filter box, thereby installing the filter plate inside the filter box. The pores of the filter plate are largest on the side closer to the water tank and smallest on the side farther from the water tank.

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figures 1-5As shown, this utility model provides a technical solution: a construction dust suppression device, including a mobile cart 1; a water tank 2 is installed at one end of the top of the mobile cart 1, and a spray dust suppression device 3 is installed at the other end of the top of the mobile cart 1; a filter box 4 is provided at the bottom of the spray dust suppression device 3; the bottom of the filter box 4 is fixed to the top of the mobile cart 1; a cover 5 is installed on the top of the filter box 4; three mounting slots 6 are fixed on both sides inside the filter box 4; a connecting plate 7 is provided at the top inside the filter box 4; three mounting frames 8 are fixed at the bottom of the connecting plate 7; the three mounting frames 8 are slidably connected to the mounting slots 6; and the three mounting frames 8... Each filter box 4 is internally equipped with a filter plate 9. A handle 18 is fixed to the top of the cover 5. Fixing components are installed at both ends of the top of the cover 5. Each fixing component includes a housing 10 fixed to both ends of the top of the cover 5. A guide groove 11 is provided on one side of the housing 10. A fixing block 12 is slidably connected inside the guide groove 11. A control block 13 is fixed to the top of the fixing block 12. A travel groove 14 that cooperates with the control block 13 is provided on the top of the housing 10. Protrusions 15 are fixed to both ends of the filter box 4. A fixing groove 16 that cooperates with the fixing block 12 is provided at the top of the protrusion 15. A spring 17 is fixed inside the guide groove 11. The other end of the spring 17... The end is fixed to the fixing block 12. The mounting frame 8 is aligned with the mounting groove 6 and installed into the interior of the filter box 4, allowing the filter plate 9 to be installed inside the filter box 4. Through the multi-layer design of the filter plate 9, a multi-stage filtration effect is achieved. The pore size of the filter plate 9 is largest on the side closest to the water tank 2 and smallest on the side furthest from the water tank 2. This multi-stage filtration method ensures filtration effectiveness while improving overall service life, reducing replacement frequency, and preventing particles of various sizes from being intercepted before reaching a single filter plate 9. After the filter plate 9 is installed inside the filter box 4, the box cover 5 is installed on top of the filter box 4. The control block 13 is then used to control the filter plate 9. The movable fixing block 12 moves and inserts into the fixing groove 16, which limits the position of the cover 5, fixing the cover 5 to the top of the filter box 4, thus ensuring the limiting of the mounting frame 8. After the fixing block 12 is inserted into the fixing groove 16, the pushing force generated by the spring 17 on the fixing block 12 can limit the fixing block 12, preventing the fixing block 12 from easily detaching from the inside of the fixing groove 16. At the same time, through the cooperation of the control block 13 and the stroke groove 14, the movement of the control block 13 can be limited, which indirectly limits the fixing block 12, preventing the fixing block 12 from detaching from the inside of the guide groove 11.

[0017] Reference Figures 2-4As shown in this embodiment: an embedded block 19 is fixed to the bottom of the cover 5, and a first soft pad 20 is fixed to the bottom of the embedded block 19; a second soft pad 21 is installed on the bottom of each mounting frame 8; a sealing strip 22 is fixed to the top of the filter box 4; a sealing groove 24 for cooperating with the sealing strip 22 is opened at the bottom of the cover 5; a third soft pad 23 is installed on the top of the sealing strip 22. When the cover 5 is installed on the top of the filter box 4, the embedded block 19 enters the top of the filter box 4, and at the same time, the first soft pad 20 presses the connecting plate 7 downward, reducing the impact of the connecting plate 7 on the mounting frame 4. When the mounting frame 8 shakes significantly, the first soft pad 20 presses down on the connecting plate 7, causing the bottom of the mounting frame 8 to come close to the bottom of the filter box 4. The second soft pad 21 at the bottom of the mounting frame 8 fills the gap between the mounting frame 8 and the bottom of the filter box 4, thus ensuring a seal and allowing water to flow through the filter plate 9. The sealing strip 22, together with the third soft pad 23 and the sealing groove 24, seals the filter box 4 and the cover 5, preventing water from flowing out through the gap between the filter box 4 and the cover 5.

[0018] Working Principle: The mounting frame 8 is aligned with the mounting groove 6 and installed into the filter box 4, allowing the filter plate 9 to be installed inside. The multi-layer design of the filter plate 9 creates a multi-stage filtration effect. The pore size of the filter plate 9 is largest on the side closest to the water tank 2 and smallest on the side furthest from the water tank 2. This multi-stage filtration method ensures filtration effectiveness while extending the overall lifespan, reducing replacement frequency, and preventing particles of various sizes from being intercepted by a single filter plate 9. After the filter plate 9 is installed into the filter box 4, the box cover 5 is installed on top of the filter box 4. The control block 13 moves the fixing block 12 and inserts it into the fixing groove 16, limiting the position of the box cover 5 and fixing it to the top of the filter box 4. This ensures the limiting of the mounting frame 8. After the fixing block 12 is inserted into the fixing groove 16, the pushing force generated by the spring 17 on the fixing block 12 further limits its position, preventing it from easily dislodging from the fixing groove 16. The internal separation, combined with the cooperation of the control block 13 and the stroke groove 14, can limit the movement of the control block 13, indirectly limiting the fixed block 12 and preventing the fixed block 12 from separating from the inside of the guide groove 11. When the cover 5 is installed on the top of the filter box 4, the embedded block 19 enters the top of the filter box 4. At the same time, the first soft pad 20 presses the connecting plate 7 downward, reducing the large-scale shaking of the mounting frame 8 caused by the connecting plate 7. The downward pressure of the first soft pad 20 on the connecting plate 7 makes the bottom of the mounting frame 8 close to the bottom of the filter box 4. The second soft pad 21 at the bottom of the mounting frame 8 can fill the gap between the mounting frame 8 and the bottom of the filter box 4, thereby ensuring the seal and allowing water to flow through the filter plate 9. The cooperation of the sealing strip 22, the third soft pad 23 and the sealing groove 24 can seal the filter box 4 and the cover 5, preventing water from flowing out through the gap between the filter box 4 and the cover 5.

[0019] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
