Description

Technical Field

[0001] This utility model relates to the field of dust suppression equipment technology, specifically to a sand and gravel workshop. Background Technology

[0002] Construction processes typically require large quantities of sand and gravel, often produced by crushing large stones. During processing, the crushing of sand and gravel generates significant amounts of dust. This dust flies throughout the sand and gravel workshop, obstructing visibility and posing health risks to construction workers. Current technology often employs multiple sprayers installed on the ceiling of the workshop to suppress dust. However, the water mist produced by these sprayers cannot completely eliminate the large amounts of dust generated during crushing, and dust at intervals between sprayers remains uncontrolled, resulting in poor dust suppression effectiveness. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sand and gravel workshop with better dust reduction effect.

[0004] To solve the above-mentioned technical problems, this utility model includes a workshop body, the structure of which is as follows: the workshop body includes workshop side walls, workshop ceiling, and workshop floor; multiple rotatable spray devices are installed on the workshop ceiling; the spray devices are connected to high-pressure water pipes; multiple drainage pipes are provided under the workshop floor; the workshop floor has a height difference; drain outlets are provided on the drainage pipes; and the drain outlets of the drainage pipes are located at the lowest point of the workshop floor.

[0005] With the above structure, a sprinkler system is installed on the workshop ceiling. Located above the workshop space, the sprinkler system allows dust to spread during sand and gravel placement and cutting. Water is supplied to the sprinkler system via high-pressure water pipes and sprayed downwards, adsorbing and dislodging the dust onto the workshop floor. The sprinkler system can rotate, causing the spray water to swirl and spread, increasing the coverage area. Multiple sprinkler systems are spaced apart, and the expanded coverage area covers the gaps between them, ensuring all dust falls to the ground. Medium-dust particles can also be sprayed, ensuring the effectiveness of dust suppression. The rotating spray system enhances the water volume, ensuring that even heavy dust particles fall to the ground. As water and dust fall together, the water flows towards the lowest point of the workshop floor due to gravity, driven by the floor's height difference. The drainage ditch, located below and at the lowest point of the workshop floor, carries the fallen dust into the ditch, removing both dust and water. This prevents dust from re-entraining after evaporation, further reducing dust concentration in the workshop, facilitating wastewater treatment, saving manpower, and improving efficiency.

[0006] The workshop ceiling is equipped with multiple rows of spray racks, and the spray devices are installed on the spray racks. The spray devices in adjacent rows are spaced apart. When the workshop area is large, multiple rows of spray racks are set up, and the spray devices are installed on the spray racks. The spray devices are spaced apart, which can better cover the area between adjacent spray devices, ensuring that every dust is sprayed to reduce dust and ensuring the dust reduction effect.

[0007] The spraying device includes a spray pipe connected to a high-pressure water pipe. A nozzle is rotatably connected to the lower end of the spray pipe. The nozzle is equipped with multiple nozzles. The water sprayed from the nozzles can drive the nozzle to rotate inside the spray pipe. The water in the high-pressure water pipe enters the central tube in the nozzle through the spray pipe, and then enters the spray pipe from the central tube. The opening of the spray pipe is horizontal, so when the spray pipe sprays water, it sprays water in a horizontal direction. The water pushes the nozzle to rotate at the same time as it is sprayed, so there is no need for an additional drive device to drive the nozzle to rotate. After the water sprays and drives the nozzle to rotate, the water is subjected to centrifugal force, which expands the spray range and ensures the dust suppression effect.

[0008] The nozzle includes a central tube and multiple spray pipes that are connected to the central tube. The central tube is rotatably connected to the spray pipes. All the multiple spray pipes are bent and the nozzles are all oriented horizontally. The bending direction of the multiple spray pipes is consistent, and the nozzles are oriented horizontally. When water flows through the spray pipes and is blown out from the nozzles, the water flow exerts a counterforce on the spray pipes. The direction of the force is also the direction of the radial tangent of the nozzle, which can drive the rotation of the nozzle, expand the spray range, and ensure the dust suppression effect.

[0009] The nozzle includes a central tube and a water spray pipe that passes through the central tube. The central tube is rotatably connected to the spray pipe. The water spray pipe is arranged radially, and multiple nozzles are provided at the radial outer end of the outer surface of the water spray pipe. The nozzles are oriented at an angle to the vertical direction. The reaction force of the water sprayed from the nozzles can act on the radial tangent of the water spray pipe, thus driving the nozzle to rotate inside the spray pipe. At the same time, the multiple nozzles expand the spray area and the uniformity of the spray, ensuring the dust suppression effect.

[0010] The upper end of the drainage pipe is equipped with a drain outlet, and a drainage cover is installed on the drain outlet. The drainage cover has multiple drainage holes. Dust and water are drained away through the drainage pipe, ensuring the cleanliness of the workshop floor. The drainage cover covers the surface of the drain outlet to prevent the drain outlet from being recessed and affecting construction and transportation. Wastewater enters the drainage cover through the drainage holes. The drainage holes ensure that wastewater and dust flow into the drainage pipe while preventing sand and gravel from falling into the drainage channel and causing blockage, thus ensuring smooth water flow.

[0011] The drainage pipe is equipped with multiple drain outlets, which are located at the four edges of the workshop floor. Water from all parts of the workshop can flow out through the nearest drain outlets, improving flow efficiency.

[0012] In summary, this utility model has the advantages of ensuring dust reduction effect, saving manpower, and improving dust reduction efficiency. Attached Figure Description

[0019] like Figure 1-6 As shown, a sand and gravel workshop includes workshop side walls, a workshop ceiling, and a workshop floor. The workshop ceiling is located above the workshop side walls. A rotating sprinkler device 2 is installed on the workshop ceiling. The sprinkler device 2 includes a sprinkler bracket 21, on which multiple nozzles are installed. The nozzles can spray water outwards. When there is dust in the workshop, water is sprayed outwards through the nozzles. The water falls from above, spraying the dust and causing it to fall onto the workshop floor. Multiple drainage pipes 3 are installed under the workshop floor. The top of the drainage pipes 3 has a drain outlet 31. The water falling on the ground mixes with the falling dust and flows into the drainage pipes 3 through the drain outlet 31. The workshop floor has a height difference, and the drain outlet 31 is located at the lowest point of the workshop floor. The sand and gravel workshop is used to store various types of sand and gravel with different densities and sizes. During the storage process, smaller gravel or dust will fill the air. A rotating spray device 2 is used. The centrifugal force generated by the rotation drives the water sprayed from the nozzle to spray outward, increasing the coverage area with the spray device 2 as the center.

[0020] like Figure 1-4As shown, the spray device 2 sprays downwards. The rotation speed of the spray device 2 is adjustable, which changes the centrifugal force. The higher the rotation speed, the larger the spray area, thus altering the spray area of ​​the spray device 2. A larger coverage area results in better dust suppression. Furthermore, the use of multiple spray devices 2 increases the covered area. Different numbers of spray devices 2 can be set according to the size of the workshop. By adjusting the number and location of the spray devices 2, all areas of the workshop are covered, ensuring effective dust suppression.

[0021] like Figure 1 , 4 As shown, the dashed line represents the spraying area of ​​the spray device 2. The spray device 2 is installed on the workshop ceiling with multiple rows of spray brackets 21. Each row of spray brackets 21 has multiple spray devices 2 evenly installed, with adjacent rows of spray devices 2 spaced apart. The spray devices 2 are evenly distributed on the workshop ceiling, ensuring that all dust particles in the workshop are sprayed evenly. The spraying area is circular, and the spaced arrangement better covers the circular gaps between adjacent spray devices 2, ensuring that every dust particle is sprayed to suppress dust, thus guaranteeing the dust suppression effect.

[0022] like Figure 1 , 2 As shown, in this embodiment, the spray device 2 includes a spray pipe connected to a high-pressure water pipe. A nozzle is rotatably connected to the spray pipe. The nozzle includes a central pipe 24 connected to multiple curved spray pipes 26, which are evenly arranged around the central pipe 24. The curvature of the spray pipes 26 is consistent, and a nozzle 27 is provided at the end of each spray pipe 26, from which water is sprayed. The nozzles 27 are oriented horizontally in opposite directions, meaning their orientation is tangent to the radial direction of the nozzle. When water flows through the spray pipes 26, it is sprayed from the nozzles 27. When water is sprayed from one end of the spray pipes 26, the reaction force of the water flow impacts the spray pipes 26, thereby driving the nozzle to rotate. When the water flow velocity is high, the impact force of the water flow reaction is greater, and the rotation speed is higher. At this time, the centrifugal force on the water flow increases, thus increasing the dust suppression range of the spray device 2. Therefore, the spray range and water volume of the spray device 2 can be adjusted according to the dust density, ensuring the dust suppression effect.

[0023] like Figure 1 , 3 As shown, Figure 3The diagram shows another embodiment of the spray device 2. In this embodiment, the spray device 2 includes a spray pipe connected to a high-pressure water pipe, and a nozzle is rotatably connected to the spray pipe. The nozzle includes a central pipe 24 and a water spray pipe 26 that passes through the central pipe 24. In this embodiment, there are three water spray pipes 26, all of which are radially arranged. The outer radial end of each water spray pipe 26 is provided with a nozzle pipe that can rotate along the axis of the water spray pipe, and multiple nozzles 27 are provided on the nozzle pipe. In this embodiment, there are four nozzles 27. In other embodiments, the number of nozzles 27 can be three or five, or other quantities. The nozzles 27 are oriented at an angle to the vertical direction, and the angle can be changed. When water is sprayed from the nozzles 27, the reaction force of the water impacts the radial tangential direction, causing the nozzle to rotate inside the spray pipe, thereby causing the spray device 2 to rotate, increasing the dust suppression range and ensuring the dust suppression effect.

[0024] like Figure 1 , 4 As shown in Figure 6, the workshop floor is sloped. In this embodiment, multiple drainage pipes 3 are laid under the workshop floor. Each pipe has a drain outlet 31 at its upper end, and a drain cover 32 with multiple drainage holes 33 on the drain cover 32. Dust and water are carried away through the drainage pipes 3, ensuring the workshop floor remains clean. The drain cover 32 covers the surface of the drain outlet 31, preventing its recess from affecting construction and transportation. Wastewater enters the drain cover 32 through the drainage holes 33. The drainage holes 33 ensure that wastewater and dust flow into the drainage pipes 3 while preventing sand and gravel from falling into the drainage channel and causing blockages, thus ensuring smooth water flow. Drain outlets 31 are located at the four edges of the workshop floor and connected to the drainage pipes. The drain outlets 31 are at the lowest points of the workshop floor. By setting drain outlets 31 at the four edges, the excessive height difference of the ground is avoided when there is only one drain outlet 31, thus balancing the height difference and facilitating the flow of water from all areas into the drainage pipes 3, avoiding drainage dead zones and ensuring drainage efficiency.

[0025] like Figure 1 , 5As shown, in other embodiments, multiple drainage ditches can also be installed on the workshop floor, with the drainage ditches located at the lowest point of the workshop floor. The drainage ditches include drainage channels installed underground, with drainage covers 32 installed on the drainage channels. The drainage covers 32 have multiple drainage holes 33. When the nozzles spray water onto the ground, the dust and sand in the workshop flow into the drainage channels through the drainage holes 33 of the drainage covers 32. The drainage channels then transport the wastewater to a wastewater pool outside the workshop, where the dust and water can be further recycled and treated. The sprayed water continues to impact the wastewater and dust washed onto the workshop floor, and the water flow flows to lower elevations due to the elevation difference of the workshop floor. The sand and gravel in the workshop are relatively large and are not affected by the water flow; the wastewater flows into the drainage ditches along with the elevation difference. When sewage passes through the drainage cover 32, it enters the drainage ditch through the drainage holes 33 provided on the drainage cover 32. The drainage cover 32 covers the upper surface of the drainage ditch, preventing the drainage ditch on the ground from affecting the transportation of sand and gravel and the movement of workers, thus ensuring production and work efficiency. The drainage holes 33 ensure the efficiency of sewage flow and discharge.
