Description

Technical Field

[0001] This utility model is a dust control device for civil engineering construction sites, belonging to the technical field of dust control equipment for civil engineering. Background Technology

[0002] Civil engineering is a general term for the science and technology of constructing various land engineering facilities. It refers to the various technical work, including surveying, planning, design, construction, installation, and maintenance, of buildings, structures, and related supporting facilities for the construction, renovation, or expansion of various projects, excluding building construction, and the completed engineering entities. Civil engineering construction generates a large amount of smoke and dust, which floats in the air around the construction site. To avoid these smoke and dust affecting the normal work of workers, dust control equipment is usually used to remove them.

[0003] Most dust control equipment currently in use adopts the method of dust suction and filtration. However, while it is suctioning and filtering dust, the airflow also causes the surrounding dust to spread and flow. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dust control device for civil engineering construction sites.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A dust control device for civil engineering construction sites includes a water tank and a dust collection box. The dust collection box is located at the top center of the water tank. The dust collection box has an air chamber and a dust collection chamber inside. The dust collection chamber is located above the air chamber. A fan is installed at the bottom of the dust collection chamber. The top input end of the fan is connected to a filter box. Several filter plates are arranged sequentially from top to bottom inside the filter box. The top of the filter box is connected to an air supply pipe installed on the top of the dust collection box through a connecting pipe. An air suction nozzle is snapped onto the top of the air supply pipe. The bottom output end of the fan extends into the air chamber. Several air outlet dust suppression components are arranged on the bottom side of the dust collection box. The air suction end of the air outlet dust suppression component is connected to the air chamber, and the water suction end of the air outlet dust suppression component is connected to the water tank.

[0007] Furthermore, the exhaust dust suppression assembly includes several air passage rotary joints disposed at the bottom side of the dust collector. The fixed end of the air passage rotary joint is connected and fixed to the dust collector and extends into the air cavity. The movable end of the air passage rotary joint is connected to the exhaust pipe. An exhaust nozzle is connected to the top of the exhaust pipe. A fixing ring is fixed at the connection between the exhaust pipe and the air passage rotary joint. Several limiting holes are opened on the outer circumference of the fixing ring.

[0008] Furthermore, a sliding member is laterally slidably connected to the outer side surface of the dust collector box and above the air passage rotary joint. The end of the sliding member extends through to the outside of the dust collector box and is connected and fixed to the connecting seat. Several sets of support rods of different lengths are provided on the outer side surface of the connecting seat. A limit rod is fixed to the end of the support rod near the dust collector box. The limit rod is adapted to the limit hole.

[0009] Furthermore, the dust suppression assembly also includes an annular pipe fixedly installed on the outside of the air outlet, the annular pipe having a plurality of nozzles extending into the interior of the air outlet, a water supply hose connected to the annular pipe, the end of the water supply hose extending into the interior of the water tank and communicating with a horizontal pipe, and the horizontal pipe being connected to a water pump.

[0010] Furthermore, a door is provided on the side of the filter box, and several slots that cooperate with the filter plate are provided on the inner walls of both the filter box and the door.

[0011] Furthermore, the bottom of the air duct is provided with an air outlet that matches the top of the connecting pipe.

[0012] Furthermore, a control box is provided on one side of the water tank, and the control box is electrically connected to the fan and the water pump.

[0013] The beneficial effects of this utility model are:

[0014] Through the design of the dust suppression component, during dust removal operations, the fan draws in air under negative pressure. The air is drawn into the filter box through the suction nozzles and air ducts, drawing in dusty air. Several layers of filter plates inside the filter box filter and adsorb the dust in the air. The filtered clean air is then delivered through the air chamber to several outlet pipes. Air is transported through the outlet pipes and the nozzles on top. Simultaneously, a water pump delivers water from the tank through flexible hoses and a ring pipe to the nozzles inside the outlets. This allows the clean airflow from the outlets to carry away the airflow from the nozzles, increasing the diffusion range of the water mist and forming a water mist dust suppression layer. This achieves a dual dust suppression effect: internal negative pressure suction and external water mist dust suppression. Furthermore, the external water mist dust suppression layer isolates the internal negative pressure suction, preventing dust diffusion during negative pressure suction.

[0015] Through the design of the air outlet dust suppression component, during dust removal operations, the angles of several air outlet pipes can be adjusted according to the needs of the construction site, so that several air outlet pipes can be in a vertical output posture or a fan-shaped diffusion state, thereby achieving external water mist dust suppression at different angles and ranges. Specifically, the angle is adjusted by rotating the air outlet pipe at the end of the air circuit rotary joint. After adjustment, the connecting seat and sliding part are pushed towards the dust collection box, thereby driving the limiting rod at the end of the support rod to move laterally and insert into the limiting hole on the fixing ring at the end of the air outlet pipe, thereby realizing the angle limiting action of the fixing ring and the air outlet pipe.

[0016] By using a design with several support rods of varying lengths, one of the limiting rods on each support rod will always engage and be fixed together with the limiting hole on the fixing ring.

[0017] The design of the door allows the filter box to be opened when the filter element inside the filter plate needs to be replaced, making it convenient to replace the filter plate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution for dust control equipment at civil engineering construction sites, including a water tank 1 and a dust collection box 2. The dust collection box 2 is located at the top center of the water tank 1. The dust collection box 2 has an air chamber 3 and a dust collection chamber 4 inside. The dust collection chamber 4 is located above the air chamber 3. A fan 6 is installed at the bottom of the dust collection chamber 4. The top input end of the fan 6 is connected to a filter box 5. A plurality of filter plates 12 are arranged sequentially from top to bottom inside the filter box 5. The top of the filter box 5 is connected to the top of the dust collection box 2 via a connecting pipe 7. The air supply pipe 8 of the part is connected, and the bottom of the air supply pipe 8 is provided with an air outlet that is adapted to the top of the connecting pipe 7. The top of the air supply pipe 8 is snapped with a suction nozzle 9. The bottom output end of the fan 6 extends into the air cavity 3. Several air outlet dust suppression components are provided on the bottom side of the dust collection box 2. The suction end of the air outlet dust suppression component is connected to the air cavity 3. The water suction end of the air outlet dust suppression component is connected to the water tank 1. A control box 25 is provided on one side of the water tank 1. The control box 25 is electrically connected to the fan 6 and the water pump 18.

[0027] See Figure 1 , Figure 5The dust suppression assembly includes several air passage rotary joints located at the bottom side of the dust collector 2. The fixed end of each rotary joint is connected to the dust collector 2 and extends into the air cavity 3. The movable end of each rotary joint is connected to an air outlet pipe 13. An air outlet nozzle 14 is connected to the top of the air outlet pipe 13. A fixing ring 19 is fixed at the connection between the air outlet pipe 13 and the rotary joint. Several limiting holes 20 are formed on the outer circumference of the fixing ring 19. A sliding member 21 is laterally slidably connected to the outer side of the dust collector 2, above the rotary joint. The end of the sliding member 21 extends to the outside of the dust collector 2 and is connected to a connecting seat 22. Several sets of support rods 23 of varying lengths are provided on the outer side of the connecting seat 22. A limiting rod 24 is fixed to the end of each support rod 23 near the dust collector 2, and the limiting rod 24 is adapted to the limiting holes 20. The dust suppression assembly is constructed by air outlet... The dust removal system is designed so that during dust removal operations, the fan 6 draws in air under negative pressure through the suction nozzle 9 and the air supply pipe 8, drawing dusty air into the filter box 5. Several layers of filter plates 12 inside the filter box 5 filter and adsorb the dust in the air. The filtered clean air is then transported through the air chamber 3 to several outlet pipes 13. Air is then transported through the outlet pipes 13 and the outlet nozzles 14 at their top. Simultaneously, the water pump 18 delivers water from the water tank 1 through the water supply hose 17 and the annular pipe 16 to the nozzles 15 inside the outlet nozzles 14. This allows the clean airflow from the outlet nozzles 14 to simultaneously carry away the airflow from the nozzles 15, thereby increasing the diffusion range of the water mist and forming a water mist dust-suppressing layer. This achieves a dual dust suppression action: negative pressure dust collection on the inner side and water mist dust suppression on the outer side. Furthermore, the outer water mist dust suppression layer effectively isolates dust from the negative pressure dust collection on the inner side, preventing dust diffusion during negative pressure dust collection.

[0028] See Figure 1 , Figure 4The dust suppression assembly also includes an annular pipe 16 fixedly mounted on the outside of the air outlet 14. The annular pipe 16 has several nozzles 15 penetrating into the air outlet 14. A water supply hose 17 is connected to the annular pipe 16, with its end penetrating into the water tank 1 and communicating with a horizontal pipe. The horizontal pipe is connected to a water pump 18. Through the design of the dust suppression assembly, during dust removal operations, the angles of several air outlet pipes 13 can be adjusted according to the needs of the construction site, allowing for various adjustments to the air outlet pipes 13. It can be in a vertical output posture or a fan-shaped diffusion state, thereby achieving dust suppression of the outer layer of water mist at different angles and ranges. Specifically, by rotating the air outlet pipe 13 to adjust the angle at the end of the air circuit rotary joint, after adjustment, by pushing the connecting seat 22 and the sliding part 21 towards the dust collector 2, the limiting rod 24 at the end of the support rod 23 is moved laterally and inserted into the limiting hole 20 on the fixing ring 19 at the end of the air outlet pipe 13, thereby realizing the angle limiting action of the fixing ring 19 and the air outlet pipe 13.

[0029] See Figure 2 , Figure 3 The filter box 5 has a door 10 on its side. Both the filter box 5 and the door 10 have several slots 11 on their inner walls that cooperate with the filter plate 12. The filter plate 12 has a filter element at its center. The door 10 allows the filter box 5 to be opened when the filter element in the filter plate 12 needs to be replaced, making it convenient to replace the filter plate 12.

[0030] The circuits and electronic components, modules and controllers, or the heat dissipation holes and maintenance doors in the space of the adapted electrical equipment are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this application does not involve improvements to software and methods or heat dissipation and maintenance.

[0031] During dust removal, the fan 6 draws in air under negative pressure through the suction nozzle 9 and the air delivery pipe 8, drawing dusty air into the filter box 5. Several layers of filter plates 12 inside the filter box 5 filter and adsorb the dust in the air. The filtered clean air is then delivered through the air chamber 3 to several outlet pipes 13. Air is transported through the outlet pipes 13 and the outlet nozzles 14 at their top. Simultaneously, the water pump 18 delivers water from the water tank 1 through the water delivery hose 17 and the annular pipe 16 to the nozzles 15 inside the outlet nozzles 14. In this way, the clean airflow output from the outlet nozzles 14 carries away the airflow output from the nozzles 15, thereby increasing the diffusion range of the water mist and forming a water mist dust-suppressing layer. This achieves a dual dust suppression action: negative pressure dust collection on the inner side of the device and water mist dust suppression on the outer side. At the same time, the outer layer of water mist dust suppression can isolate the dust from the inner negative pressure dust suction, preventing the dust from spreading during negative pressure dust suction. At the same time, during dust removal work, the angle of several air outlet pipes 13 can be adjusted according to the needs of the construction site, so that several air outlet pipes 13 can be in a vertical output posture or a fan-shaped diffusion state, thereby achieving outer water mist dust suppression at different angles and ranges. Specifically, by rotating the air outlet pipe 13 at the end of the air circuit rotary joint to adjust the angle, after the adjustment is completed, by pushing the connecting seat 22 and the sliding part 21 towards the dust collection box 2, the limiting rod 24 at the end of the support rod 23 is driven to move laterally and then inserted into the limiting hole 20 on the fixing ring 19 at the end of the air outlet pipe 13, thereby realizing the angle limiting action of the fixing ring 19 and the air outlet pipe 13.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
