Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and more specifically, it relates to a dust control device for engineering construction. Background Technology

[0002] In engineering construction scenarios, the large amount of dust generated during construction not only pollutes the surrounding environment but may also threaten the health of construction workers. Therefore, dust control measures have become a necessary means on construction sites. In existing technologies, water mist is usually sprayed into the air to reduce dust. The sprayed water mist can adsorb dust particles in the air and cause them to settle, thereby playing a role in dust reduction.

[0003] During construction, the required water flow rate for spraying varies at different stages and in different scenarios. For example, when there is less dust, the water flow rate can be reduced to save water resources, while areas with higher dust concentrations require a larger water flow rate to ensure dust suppression. However, existing spraying devices usually cannot achieve precise control of water flow rate, resulting in water waste or poor dust suppression effect. To solve these problems, there is an urgent need for a device that can flexibly adjust the spraying range, direction, and water flow rate to adapt to various construction environments and dust suppression needs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a dust control device for engineering construction, which solves the technical problem mentioned in the background art that the existing spray devices usually cannot achieve precise control of water flow, resulting in water waste or poor dust reduction effect.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for engineering construction, comprising a mobile vehicle, on which a dust suppression mechanism is installed. The dust suppression mechanism includes a water tank, a water pump, a bend pipe, a diverter pipe, a delivery pipe, and nozzles. The water tank and the water pump are mounted on the mobile vehicle. The bend pipe is installed at both ends of the water pump and connected to the water tank. The diverter pipe is installed on the bend pipe. The delivery pipe is installed at the top of the connecting pipe. The nozzles are installed at the top of two sets of delivery pipes. Adjustment mechanisms are provided at both ends of the diverter pipe. The segmentation mechanism includes an installation sleeve, a rotating sleeve, a connecting sleeve, an arc-shaped block, a central rod, a spiral groove, a connecting disc, an adjusting sleeve, a flow passage hole, and a sealing ring. The installation sleeve is installed at the bottom end of the delivery pipe. The rotating sleeve rotatably connects the installation sleeve and the diversion pipe. The connecting sleeve is installed on the inner wall of the rotating sleeve. The arc-shaped block is installed on the inner wall of the connecting sleeve. The central rod is installed inside the connecting sleeve. The spiral groove is located on the outer wall of the central rod. The connecting disc is installed at the top end of the central rod. The adjusting sleeve is installed on the bottom surface of the connecting sleeve. The flow passage hole is located on the outer wall of the adjusting sleeve. The sealing ring is installed on the inner wall of the installation sleeve.

[0008] The present invention is further configured such that a water injection pipe is provided at the top of the water tank. The water injection pipe facilitates the replenishment of water into the water tank, enabling rapid replenishment of water resources inside the water tank, ensuring that dust suppression operations can continue, and preventing the device from stopping operation due to insufficient water supply.

[0009] The present invention is further provided that a cap is installed at the top of the water injection pipe, and the cap and the water injection pipe are connected by a thread. The cap can effectively prevent external dust or debris from entering the water tank, thereby protecting the cleanliness of the water source. At the same time, the threaded connection facilitates the disassembly and installation of the cap, ensuring the convenience of water injection operation and sealing performance.

[0010] The present invention is further configured such that the two sets of the bend pipes are respectively installed at the inlet and outlet of the water pump. The bend pipes can effectively guide the direction of water flow. The setting at the inlet of the water pump ensures that the water in the water tank can smoothly enter the water pump, and the setting at the outlet ensures that the pressurized water can be efficiently delivered to the diversion pipe, so as to realize the smooth flow and reasonable distribution of water resources in the entire dust suppression device.

[0011] The present invention is further configured such that both sets of nozzles are atomizing nozzles. The atomizing nozzles can disperse water into fine water mist particles, thereby significantly increasing the contact area and adsorption efficiency between water and dust particles in the air, achieving the purpose of efficient dust reduction. At the same time, the atomized water flow can also avoid the problem of water accumulation caused by large water flow spraying, thus improving the practicality and environmental performance of the device.

[0012] The present invention is further configured such that two sets of arc-shaped blocks are installed on the inner wall of the connecting sleeve, and two sets of spiral grooves are distributed on the outer wall of the central rod and slidably connected with the two sets of arc-shaped blocks. The combined use of the arc-shaped blocks and spiral grooves enables the central rod to move longitudinally through rotation, thereby driving the adjusting sleeve to change the opening and closing state of the flow hole, and realizing precise adjustment of water flow. At the same time, the design of the two sets of arc-shaped blocks and spiral grooves improves the stability of the structure and the adjustment accuracy.

[0013] The present invention is further configured such that the inner walls of the adjusting sleeve and the sealing sleeve are both polygonal and slidably connected. The polygonal design of the adjusting sleeve and the inner walls of the sealing sleeve can effectively prevent the adjusting sleeve from rotating during the sliding process, ensuring that the adjusting sleeve only slides longitudinally, thereby ensuring the accuracy and reliability of water flow adjustment. At the same time, the sliding connection reduces friction and improves the operation performance and durability of the device.

[0014] The present invention is further configured such that multiple sets of flow holes are distributed on the outer wall of the regulating sleeve. The design of multiple sets of flow holes improves the uniformity and flexibility of water flow through the regulating sleeve. By adjusting the number of flow holes that are open and closed, the water flow rate can be precisely controlled, thereby meeting the spraying water volume requirements of different dust suppression environments. At the same time, the flow holes distributed on the outer wall of the regulating sleeve have a simple structure, are easy to process and maintain, and effectively reduce manufacturing costs and usage difficulty.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a dust control device for engineering construction, which has the following beneficial effects:

[0017] 1. The spraying system has the function of spraying water mist into the air through atomizing nozzles, which can effectively adsorb dust particles in the air and achieve the purpose of rapid dust suppression. At the same time, the water tank is used as a water storage container, and the water is drawn and pressurized by the water pump to smoothly deliver water to the nozzles, realizing the efficient use of water resources. In addition, through the combined use of bend pipes and diversion pipes, the water flow can be flexibly distributed to different delivery pipes, thereby achieving simultaneous dust suppression in multiple areas and meeting the multi-faceted dust suppression needs of the construction site.

[0018] 2. The adjustment mechanism rotates the rotating sleeve, which drives the connecting sleeve and the arc block to rotate. Furthermore, through the cooperation of the spiral groove and the arc block, the central rod moves longitudinally, thereby pushing the adjustment sleeve to slide along the sealing ring. Ultimately, this changes the opening area and number of the flow holes. This design can flexibly adjust the water flow rate, avoiding the problem of uncontrollable water flow in traditional devices. It not only effectively improves the dust suppression effect but also saves water resources and adapts to the precise water flow requirements of different scenarios.

[0019] 3. The combined use of the arc-shaped block and the spiral groove, through their threaded engagement, allows the central rod to move smoothly along the longitudinal direction. By cooperating with the adjusting sleeve and the flow passage, the size of the water flow can be flexibly changed. This structural design is simple and reliable. It can not only achieve precise adjustment, but also effectively avoid mechanical failure problems caused by complex structures, thereby improving the service life and maintenance convenience of the device.

[0030] Water tank 2 is equipped with a water injection pipe 18 at the top.

[0031] A cap 19 is installed at the top of the water injection pipe 18, and the cap 19 and the water injection pipe 18 are connected by threads.

[0032] Two sets of bends 4 are installed at the inlet and outlet of the water pump 3, respectively.

[0033] Both sets of nozzles 7 are set as atomizing nozzles.

[0034] Two sets of arc-shaped blocks 11 are installed on the inner wall of the connecting sleeve 10, and two sets of spiral grooves 13 are distributed on the outer wall of the central rod 12 and are slidably connected to the two sets of arc-shaped blocks 11.

[0035] The adjusting sleeve 15 and the inner wall of the cover are both polygonal and slidably connected.

[0036] Multiple sets of flow holes 16 are distributed on the outer wall of the regulating sleeve 15.

[0037] In this embodiment, the water tank 2 is the water storage container of the device, storing water and providing a stable water supply for dust suppression. Water is injected into the water tank 2 through the water injection pipe 18. The water pump 3 is installed next to the water tank 2 to draw water from the water tank 2 and pressurize it, ensuring that the water can be smoothly delivered to the nozzle 7. There are two sets of bend pipes 4, which are connected to the inlet and outlet ends of the water pump 3, respectively. The bend pipe 4 at the inlet end draws water from the water tank 2, and the bend pipe 4 at the outlet end is connected to the diversion pipe 5 to facilitate water delivery. 5 is connected to the bend pipe 4, which divides the water from the water pump 3 into different flow directions and provides it to multiple sets of delivery pipes 6.

The rotating sleeve 9 movably connects the mounting sleeve 8 to the diversion pipe 5 and has a rotation function, which can adjust the direction of the nozzles 7.

[0038] More specifically, when the water flow needs to be adjusted, rotating the rotating sleeve 9 drives the connecting sleeve 10 to rotate. The rotation of the connecting sleeve 10 drives the two sets of arc-shaped blocks 11 on the inner side to rotate. The two sets of arc-shaped blocks 11 form a threaded engagement with the spiral groove 13 on the outer wall of the central rod 12, thereby driving the central rod 12 to move longitudinally along the connecting sleeve 10. The central rod 12 drives the adjusting sleeve 15 to move. The adjusting sleeve 15 slides along the sealing ring 17, thereby changing the number of multiple sets of flow holes 16 on the outer wall of the adjusting sleeve 15 blocked by the sealing ring 17, changing the flow space of the water flow. By adjusting the number of flow holes 16 on the adjusting sleeve 15, the water flow of each nozzle 7 is controlled.

[0039] In summary, during the use or operation of the overall equipment: Water tank 2 serves as the water storage container for the device, storing water and providing a stable water supply for dust suppression. Water is injected into water tank 2 through water injection pipe 18. Water pump 3 is installed next to water tank 2 to draw water from the water tank 2 and pressurize it, ensuring that the water can be smoothly delivered to nozzle 7. There are two sets of bend pipes 4, connected to the inlet and outlet ends of water pump 3 respectively. The bend pipe 4 at the inlet end draws water from water tank 2, and the bend pipe 4 at the outlet end connects to the diversion pipe 5 to facilitate water delivery. The diversion pipe 5 is connected to the bend pipe 4, which divides the water from the water pump 3 into different flow directions and provides it to multiple sets of delivery pipes 6. The delivery pipes 6 are used to further deliver the water from the diversion pipe 5 to the nozzles 7. Two sets of nozzles 7 are installed at the top. The nozzles 7 are atomizing nozzles, which are responsible for spraying water into the air through atomization to form water mist, which can effectively adsorb dust particles in the air and achieve dust reduction. The rotating sleeve 9 movably connects the mounting sleeve 8 to the diversion pipe 5 and has a rotation function, which can adjust the direction of the nozzles 7.

[0040] When the water flow needs to be adjusted, rotating the rotating sleeve 9 drives the connecting sleeve 10 to rotate. The rotation of the connecting sleeve 10 drives the two sets of arc-shaped blocks 11 on the inner side to rotate. The two sets of arc-shaped blocks 11 form a threaded engagement with the spiral groove 13 on the outer wall of the central rod 12, thereby driving the central rod 12 to move longitudinally along the connecting sleeve 10. The central rod 12 drives the adjusting sleeve 15 to move. The adjusting sleeve 15 slides along the sealing ring 17, thereby changing the number of multiple sets of flow holes 16 on the outer wall of the adjusting sleeve 15 blocked by the sealing ring 17, changing the flow space of the water. By adjusting the number of flow holes 16 on the adjusting sleeve 15, the water flow of each nozzle 7 is controlled.
