TECHNICAL FIELD
[0001] The present application relates to the technical field of building construction, in particular to a building construction dust falling device. BACKGROUND
[0002] When constructing underground shopping malls, subway station halls / platforms, underground laboratories and other places, ordinary ceramic tiles have been difficult to meet the dual demands of durability and aesthetics. These areas have large traffic and high use frequency, and the ceramic tiles are prone to wear and tear, cracking, and insufficient stain resistance, resulting in high cleaning and maintenance costs. At this time, stone materials such as granite have become the preferred choice due to their significant advantages: their high wear resistance can withstand high-frequency traffic and vehicle friction, their stain resistance is better after sealing treatment, and stains are easy to clean; natural texture and high-quality materials can improve the space level and are often used for floor parquet to improve aesthetics. At the same time, granite has strong adaptability and can be cut on site to meet special modeling needs, and is widely used in such places.
[0003] A large amount of dust is generated during stone cutting, which can seriously affect the construction environment and personnel health if not handled in time. Water mist is usually sprayed by using mist cannons, spray heads and other equipment to wrap dust particles in the air with water mist to make them settle to achieve the purpose of dust falling. However, when constructing underground shopping malls, subway station halls and other underground places, due to the fact that such underground spaces are usually relatively closed and have limited ventilation conditions, the water vapor is difficult to quickly disperse after water mist is sprayed, which can cause a sudden increase in environmental humidity and cause problems such as concrete structure moisture return and steel corrosion that affect the quality of the project. At the same time, underground places are often densely packed with electrical pipelines and other electrical equipment, and water mist may seep into the equipment and cause short circuits, posing a great safety hazard. In addition, the humid environment can also cause the cut stone surface to absorb water vapor, affecting the adhesion effect of the adhesive during subsequent paving, and easily causing phenomena such as hollowing and falling. Therefore, when cutting stone in underground places, other more suitable dust falling means need to be used. SUMMARY

DETAILED DESCRIPTION
[0031] In order to make the technical personnel in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.
[0032] As Figures 1 to 9 shown, the building construction dust falling device provided by the embodiment of the present application comprises a base 1 and an upper shell 11 mounted thereon, the front side of the upper shell 11 is provided with an air inlet 12, the rear side in the upper shell 11 is fixedly connected with a fan 13, and the device further comprises:
[0033] The base 1 contains water, the mesh cylinder 2 is rotatably installed in the base 1, and the two ends of the mesh cylinder 2 are fixedly connected with connecting frames 21, and the mesh cylinder 2 is partially immersed in the water;
[0034] The transmission mechanism 3 comprises a main shaft 31 rotatably installed in the base 1, the outer shell 32 is rotatably installed on the main shaft 31, the outer shell 32 is fixedly sleeved in the connecting frame 21, the fixed frame 33 is rotatably installed in the inner part of the outer shell 32, the fixed frame 33 is fixedly connected to the side of the base 1, the main shaft 31 penetrates through the fixed frame 33 and makes the outer shell 32 rotate at a lower speed than the main shaft 31 through a gear set;
[0035] The beating device 5 is sleeved on the main shaft 31 to beat the water body when the main shaft 31 rotates;
[0036] The cleaning frame 4 is fixedly connected between the two symmetrical fixed frames 33, a plurality of cleaning brushes 41 are slidably connected on the cleaning frame 4, and the cleaning brushes 41 move along the axial direction of the mesh cylinder 2.
[0037] In the embodiment, the driving motor 8 is a speed reducer, the main shaft 31 rotates at a lower speed to avoid the fins 52 from quickly entering and leaving the water body, thereby reducing the service life of the fins 52, and since the mesh cylinder 2 rotates at a lower speed, the water on the surface of the mesh cylinder 2 will not be separated due to rapid rotation, so that the stone paste attached to the mesh cylinder 2 can be quickly cleaned when the external dust is attached to the mesh cylinder 2.
[0038] In the present application, by using the net cylinder 2 which is constantly rotating in the water body, the holes on the net cylinder 2 form a water film after leaving the water body, which adsorbs the dust in the air entering the device, while the net cylinder 2 rotates to adsorb the dust, the fins 52 in the beating device 5 in the net cylinder 2 are pushed by the spring 54 to rotate quickly during the process of leaving the water body, so as to beat the water body close to the fan 13, at this time, the vibration of this part will form an impact on the holes on the adjacent net cylinder 2, so as to break the water film wrapped with dust, and the water wave will flush these holes, so that the water wrapped with dust will separate from the net cylinder 2 and enter the water body, so that these holes can continue to capture dust using the water film in the inside after leaving the water body again.
[0039] When the net cylinder 2 rotates, the residual stone paste on the outer surface of the net cylinder 2 can be cleaned by the cleaning tools such as scrapers, brushes and the like fixed in the base 1, but the stone paste attached in the inside of the net cylinder 2 is prone to cause the cleaning effect to decrease due to the viscous nature of the stone paste when using the fixed scrapers, brushes and the like to clean, therefore, by setting the cleaning brush 41, when the beating device 5 rotates with the main shaft 31, the repulsive force generated by the second magnet 55 on the fin 52 to the first magnet 42 will push the cleaning brush 41 to move along the axis direction of the net cylinder 2, so as to avoid the bristles of the cleaning brush 41 staying in the same place to cause the stone paste to adhere on the bristles over time, and ensure that the cleaning brush 41 can be used continuously, and using the repulsive force of the magnet to push the cleaning brush 41 can also prevent the fin 52 from colliding with the cleaning brush 41 during the rotation process to cause the fin 52 to bend and damage.
[0040] In an embodiment of the present application, the inner part of the upper shell 11 is fixedly connected with the partition plate 14, which prevents the suction force of the fan 13 from directly acting on the net cylinder 2.
[0041] As shown in Figure 5 As shown in the drawings, a plurality of partition plates 14 are arranged in the upper shell 11, at this time, after the fan 13 sucks the dust-containing air outside through the air inlet 12, the dust-containing air will enter the inside of the net cylinder 2 along the air inlet 12, so as to be adsorbed by the water film in the holes on the net cylinder 2, avoiding the dust entering the fan 13 to cause damage to the fan 13, and preventing the water film in the holes close to the fan 13 after the water outlet of the net cylinder 2 from being broken by the air flow to cause the water quantity to decrease and unable to capture the dust in the air, and the output pipeline of the filter 7 can be arranged above the partition plate 14, so as to make the clean water flow flush the partition plate 14 when the filtered water is fed back into the base 1.
[0042] In one embodiment of the present application, the gear set comprises a sun gear 34, a plurality of planet gears 35 and a ring gear 36, the gear set is located in the housing 32, the sun gear 34 is fixedly sleeved on the main shaft 31, the plurality of planet gears 35 are rotatably installed in the interior of the fixed frame 33, the ring gear 36 is fixedly sleeved in the housing 32, the sun gear 34 and the ring gear 36 are drivingly connected through the planet gears 35, and the gear set enables the meshing tube 2 to rotate at a speed lower than that of the main shaft 31.
[0043] When the main shaft 31 starts to rotate, the sun gear 34 on the main shaft 31 starts to rotate, thereby enabling the ring gear 36 to start to rotate in the opposite direction through the planet gears 35, and when the main shaft 31 rotates counterclockwise, the fins 52 enter the water body from the direction close to the air inlet 12 and leave the water body from the direction close to the fan 13, and since the rotation direction of the meshing tube 2 is opposite at this time, the holes capturing the dust move along with the meshing tube 2 rotating clockwise, thereby enabling the dust in the subsequent air sucked in to be captured by the water film in the holes on the meshing tube 2 leaving the water body immediately, avoiding the water film from being broken in the process of the rotation of the meshing tube 2 and failing to effectively capture the dust, ensuring that the device can use the meshing tube 2 to continuously capture the dust, thereby ensuring the dust-settling effect of the device.
[0044] In one embodiment of the present application, the beating device 5 comprises a mounting ring 51 fixedly sleeved on the main shaft 31, a plurality of fins 52 centrally symmetrically sleeved on the mounting ring 51, a plurality of limiting frames 53 centrally symmetrically fixedly connected to the mounting ring 51, a guide ring fixedly connected in the limiting frame 53, the fins 52 being penetrated by the guide ring, and springs 54 elastically connected between the fins 52 and the limiting frame 53.
[0045] As shown in Figs. Figure 6 and Figure 9 When the main shaft 31 drives the beating device 5 to rotate, the fins 52 start to enter the water surface, the fins 52 are blocked by the water body, the springs 54 are compressed, the fins 52 are about to leave the water body along with the continuous rotation of the main shaft 31, the water body cannot exert enough pressure on the fins 52 to compress the springs 54, the springs 54 push the fins 52 to rotate, the fins 52 impact the water surface at this time, the holes on the meshing tube 2 close to the impact point are splashed by the water, thereby flushing away the stone slurry blocking the holes on the meshing tube 2, ensuring that the holes can accumulate water to form a water film for capturing the dust in the subsequent dust-containing air.
[0046] Meanwhile, a part of the water splashed by the beating of the fins 52 is thrown to the inner wall of the meshing tube 2, and the part of the water splashed when contacting the meshing tube 2, thereby increasing the humidity in the base 1, ensuring the dust-settling effect.
[0047] In one embodiment of the present application, the fin 52 is embedded with a second magnet 55 at one end away from the mounting ring 51, and the inside of the cleaning brush 41 is embedded with two symmetrical first magnets 42, and the second magnet 55 repels the first magnet 42 when it is close to the first magnet 42 and pushes the cleaning brush 41 to move away from the second magnet 55.
[0048] With the rotation of the main shaft 31 driving the beating device 5, when the fin 52 enters the water, the second magnet 55 gradually approaches the first magnet 42 with the rotation of the fin 52. At this time, when the cleaning brush 41 is in the advancing direction of the fin 52, the first magnet 42 drives the cleaning brush 41 to slide away from the fin 52 due to the repulsion between the first magnet 42 and the second magnet 55. At this time, the bristles at the bottom of the cleaning brush 41 will clean the inner wall and the hole of the mesh cylinder 2, thereby avoiding the formation of viscous substances due to the accumulation of stone powder on the hole and the inner wall of the mesh cylinder 2, and ensuring that the air outside can smoothly pass through the hole of the mesh cylinder 2 after being sucked into the base 1, thereby ensuring the suction effect of the device on the dust-containing air outside.
[0049] In the present application, the mesh cylinder 2 can be made of a plastic mesh bent into a cylindrical shape, which not only avoids the magnetic force of the magnet acting on the mesh cylinder 2, but also reduces the weight of the mesh cylinder 2, and the plastic material is also more corrosion-resistant.
[0050] In one embodiment of the present application, the base 1 is fixedly connected with a filter 7 on one side, and the filter 7 is in communication with the inside of the base 1, and the filter 7 filters the impurities in the water in the base 1.
[0051] The filter 7 is provided to circulate and treat the water in the base 1, ensuring that the content of stone powder in the water in the base 1 is within a suitable range, avoiding excessive stone powder content, which increases the resistance of the water body and blocks the mesh of the mesh cylinder 2, thereby ensuring the suction and filtration effect of the device on the dust-containing air outside.
[0052] In one embodiment of the present application, the filter 7 is fixedly connected with a driving motor 8 on the top surface, and the output shaft of the driving motor 8 is drivingly connected with the main shaft 31 through a shaft coupling.
[0053] Working principle:
[0054] In use of the present application, first, the device is set near the stone cutting device, with the air inlet 12 aligned with the dust outlet of the stone cutting device, then the driving motor 8 is started to drive the main shaft 31 to rotate, at this time, under the action of the transmission mechanism 3, the meshing cylinder 2 starts to rotate, and the holes opened on the meshing cylinder 2 will remain water, so as to capture and wrap the dust to form stone slurry after contacting with the dust (due to less water in the holes, the viscosity of the stone slurry is very small), at this time, as the meshing cylinder 2 continues to rotate, the water in the holes will flow to the inside of the meshing cylinder 2 under the action of gravity, and when the stone slurry is near the horizontal plane with the meshing cylinder 2, the water body is scoured by the flapping of the fins 52 rotating with the main shaft 31, so that the stone slurry is separated from the holes and enters the water body, and finally separated by the filter 7 arranged.
[0055] When the stone slurry adheres to the inner surface of the meshing cylinder 2 during the flow process, the flapping impact of the fins 52 on the water cannot make the stone slurry separate, and this part of the stone slurry will be rubbed by the cleaning brush 41 located on the inside of the meshing cylinder 2 after entering the position of the cleaning frame 4, so that the stone slurry is separated from the meshing cylinder 2.
[0056] During the rotation of the fins 52, as the second magnet 55 approaches the first magnet 42, the cleaning brush 41 is pushed away from the fins 52 by the repulsion between the two magnets, at this time, the bristles of the cleaning brush 41 appear transverse swing, so that the stone slurry adhered in the bristles is exposed in the water body and separated from the cleaning brush 41 with the movement of the cleaning brush 41, so as to ensure the cleaning effect of the cleaning brush 41.
[0057] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above figures and description are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
