Description

Technical Field

[0001] This invention relates to the field of building demolition technology, specifically to a dust suppression machine for building demolition construction. Background Technology

[0002] During the demolition of buildings or other structures, a large amount of dust is generated, which can gradually spread over a wide area. To reduce dust and minimize its spread, dust suppression machines are used during demolition work. These machines suppress dust by spraying water mist. For example, a dust suppression device for building demolition operations, with announcement number CN222092870U, includes a dust suppression machine body, a cleaning mechanism, and a disassembly mechanism. The dust suppression machine body has a dust suppression cannon on top, a filter screen behind the cannon, a cleaning mechanism on one side of the filter screen, and the disassembly mechanism inside the cannon. The cleaning mechanism includes a motor, an output rod, a rotating rod, and a cleaning plate. The motor is installed inside the cannon and located on one side of the filter screen. This solution addresses the problem of existing dust suppression equipment where the filter screen gradually accumulates a large amount of dust, particulate matter, and other impurities, leading to filter clogging. Clogged filters affect the normal air intake and water mist spraying of the mist cannon, reducing the equipment's efficiency. Furthermore, replacing or cleaning the filter screen is cumbersome for workers, increasing operating costs and wasting unnecessary manpower.

[0003] For example, a dust suppression device for building demolition, with announcement number CN214635024U, belongs to the technical field of dust suppression devices. It includes a water tank, a water pump, nozzles, and a suction pipe. The water pump is placed on the upper surface of the water tank, with one end fixedly connected to the suction pipe. The end of the suction pipe away from the water pump is located at the bottom of the water tank. Two nozzles are provided, and two support pillars are rotatably connected to the upper surface of the water tank. The two nozzles are hinged to the tops of the two support pillars. A moving mechanism is provided on the circumferential sidewalls of the support pillars to drive the nozzles to rotate around their own rotation axis. Rotating gears are fixedly installed at the bottom ends of the two support pillars, and a driving mechanism for driving the two rotating gears is provided on the upper surface of the water tank. A three-way pipe is fixedly connected to the other end of the water pump, with one end connected to the water pump outlet and the other two ends fixedly connected to flexible hoses. Two flexible hoses penetrate the upper surface of the water tank and are connected to the nozzles. This device increases the dust suppression area. However, the above-mentioned dust suppression equipment still has the following drawbacks in actual use:

[0004] 1. Traditional dust suppressors have a limited spraying range during use. Due to the limited rotation angle of the spray structure, simply changing the spraying angle and adjusting the horizontal position will still limit the spraying range. Changing the spraying angle and adjusting the horizontal position to expand the spraying range is a common method used by existing dust suppressors.

[0005] 2. Furthermore, traditional dust suppression machines have limited spraying distance, making it inconvenient to adjust the spray distance according to construction needs. At the same time, during the spraying process, a large amount of liquid will drip from the area near the dust suppression machine, which not only makes the ground wet but also wastes water resources.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing dust suppression machines. Summary of the Invention

[0007] The purpose of this invention is to provide a dust suppression machine for building demolition construction, in order to solve the problems mentioned in the background art. Traditional dust suppression machines only use the method of changing the spray angle and adjusting the horizontal position, which still limits the spray range. In addition, traditional dust suppression machines are not convenient to adjust the spray distance according to construction needs. At the same time, during the spraying process, a large amount of liquid drips from the area near the dust suppression machine.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a dust suppression machine for building demolition, comprising a water storage base, a water pump installed inside the water storage base, the water pump being connected to one end of a water supply pipe, the other end of the water supply pipe being connected to one end of a dust suppression cylinder, and a motor installed inside the other end of the dust suppression cylinder, with fan blades installed on the output shaft of the motor, the fan blades being used to increase the spray distance; further comprising: a first annular pipe fixed to the inner wall of the dust suppression cylinder near the water supply pipe, the first annular pipe being interconnected with the water supply pipe, and first nozzles being installed at equal angles on the first annular pipe; a support frame fixed to the upper surface of the water storage base, the dust suppression cylinder being rotatably mounted on the inner side of the support frame, the angle of the dust suppression cylinder being adjustable by a telescopic rod, and an expansion mechanism being provided in the middle position of the dust suppression cylinder, the expansion mechanism being used to expand the spray range.

[0009] Preferably, the expansion mechanism includes an outer ring sleeved outside the dust collection cylinder, and the outer ring and the dust collection cylinder are rotatably connected. A second nozzle is provided at an equal angle on the outer side of the outer ring, and the outer ring is hollow. The spray range can be expanded through the second nozzle outside the outer ring.

[0010] Preferably, the outer ring has a liquid inlet hole at an equal angle on the side near the dust settling cylinder, and the outer ring is interconnected with the interior of the second ring tube through the liquid inlet hole, the connecting hole and the liquid outlet hole. The connecting hole is set at an equal angle on the outer wall of the dust settling cylinder, and the liquid outlet hole is set at an equal angle on the side of the second ring tube that is in contact with the dust settling cylinder. When the outer ring rotates, the liquid is connected.

[0011] Preferably, the second ring tube is fixed to the inner wall of the dust collection cylinder, and the second ring tube is connected to the first ring tube through a connecting tube. The side of the outer ring near the dust collection cylinder is fixedly connected to one end of the connecting rod, and a movable groove is provided on the dust collection cylinder outside the connecting rod. The connecting rod and the dust collection cylinder form a sliding structure through the movable groove. When the outer ring rotates, the inner ring can be driven to rotate synchronously through the connecting rod.

[0012] Preferably, the other end of the connecting rod is fixed with an inner ring, which is fitted and rotates against the inner wall of the dust collection cylinder. The inner ring is hollow, and a through fixing hole is opened at an equal angle on the upper part of the inner ring. The fixing hole is connected to the connecting cover through a through hole. The rotation angle of both the inner ring and the outer ring is less than 30°, and the gas can be connected when the inner ring rotates.

[0013] Preferably, the through hole is opened at an angle on the surface of the dust collection cylinder, and the connecting cover is fixed at an angle to the surface of the dust collection cylinder. A jet pipe connected to the connecting cover is fixed on the side of the connecting cover. At the same time, the end of the jet pipe near the second nozzle is inclined so that when the gas is discharged from the jet pipe, it can blow towards the position of the second nozzle to diffuse the water mist.

[0014] Preferably, the dust collection cylinder is provided with a distance adjustment mechanism at one end near the fan blades. The distance adjustment mechanism is used to adjust the spraying distance and includes a fixing plate fixed to the inner wall of the dust collection cylinder. The surface of the fixing plate is evenly provided with holes. The spraying distance can be adjusted by the cooperation of the fixing plate and the movable plate.

[0015] Preferably, a movable plate is attached to the side of the fixed plate, and both the fixed plate and the movable plate are fan-shaped structures with equal angles. The interior of the movable plate is fixedly connected to the worm wheel shaft of the worm gear mechanism. At the same time, an adjusting rod is fixed on the worm wheel shaft of the worm gear mechanism. The adjusting rod rotates through the dust collection cylinder. When the adjusting rod is rotated, the movable plate can be driven to rotate through the meshing transmission of the worm gear mechanism.

[0016] Preferably, the side of the water storage base is provided with a recycling mechanism, which is used to recycle the liquid dripping during spraying. The recycling mechanism includes a sleeve plate fixed to the water storage base, and a connecting plate passes through the end of the sleeve plate away from the water storage base. Liquid dripping near the dust suppressor can fall onto the sleeve plate and the connecting plate.

[0017] Preferably, the connecting plate and the sleeve plate are slidably connected, and both have arc-shaped cross-sections. The bottom edge of the sleeve plate is flush with the lowest point of the return channel. At the same time, the sleeve plate is connected to the interior of the water storage base through the return channel, and the recovered liquid flows into the interior of the water storage base through the return channel.

[0018] Compared with the prior art, the beneficial effects of this invention are: the dust suppression machine for building demolition construction increases the spraying range by adding nozzles to the outside of the dust suppression cylinder. Compared with the traditional method of changing the spraying angle and adjusting the horizontal position, it can further expand the spraying range, and the spraying distance can be adjusted. It can also recover the liquid dripping near the dust suppression machine, reducing the waste of water resources. The specific details are as follows:

[0019] 1. Rotating the outer ring makes the inlet hole, connecting hole and outlet hole coincide, so that part of the liquid in the first ring tube can be transferred to the second ring tube through the connecting pipe, and then transferred to the cavity of the outer ring, and finally discharged from the second nozzle, which can expand the spray range;

[0020] Furthermore, when the outer ring rotates, it drives the inner ring to rotate synchronously through the connecting rod. After the inner ring rotates, the fixing hole and the through hole are connected, so that the wind force generated by the fan blade rotation can enter the connecting cover and finally enter the jet pipe and be sprayed out, so that the water mist sprayed from the second nozzle can be distributed more widely.

[0021] 2. By changing the overlap range of the movable plate and the fixed plate, the air volume blown towards the nozzle can be adjusted. When the movable plate and the fixed plate are completely intersected, the air volume is the smallest, and when the movable plate and the fixed plate are completely overlapped, the air volume is the largest. The spray distance can be adjusted according to the air volume.

[0022] 3. Pull out the connecting plate inside the sleeve. This way, the dripping liquid can fall onto the connecting plate and the sleeve, and then flow along its slope through the return channel into the water storage base 1, thus recovering some of the water resources and reducing waste.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-10 The present invention provides the following technical solution:

[0036] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a dust suppression machine for building demolition, comprising a water storage base 1, a water pump installed inside the water storage base 1, and the water pump connected to one end of a water supply pipe 2. The other end of the water supply pipe 2 is connected to one end of a dust suppression cylinder 3, and a motor is installed inside the other end of the dust suppression cylinder 3. A fan blade 14 is mounted on the output shaft of the motor, and the fan blade 14 is used to increase the spray distance. It also includes a first annular pipe 5, fixed to the inner wall of the dust suppression cylinder 3 near the water supply pipe 2, the first annular pipe 5 and the water supply pipe 2 being interconnected. The device is connected to the first ring pipe 5, and the first nozzle 6 is installed at an equal angle on the first ring pipe 5. The support frame 4 is fixed to the upper end face of the water storage base 1. The dust suppression cylinder 3 is rotatably installed on the inner side of the support frame 4. The angle of the dust suppression cylinder 3 is adjusted by the telescopic rod. An expansion mechanism is set in the middle position of the dust suppression cylinder 3. The expansion mechanism is used to expand the spray range. First, the device is pushed to the designated position. Then, the water pump in the water storage base 1 is operated to transmit the liquid through the water pipe 2 to the first ring pipe 5. Finally, it is sprayed out from the first nozzle 6 to spray dust. During the spraying process, the wind force generated by the rotation of the fan blade 14 makes the spraying distance farther.

[0037] Existing dust suppression machines have a limited spray range during operation. Due to the limited rotation angle of the spray structure, simply changing the spray angle and adjusting the horizontal position still limits the spray range. Therefore, changing the spray angle and adjusting the horizontal position to expand the spray range is a common method used in current dust suppression machines. Figures 1-2 and Figures 5-9As shown, the extension mechanism includes an outer ring 9 sleeved around the outside of the dust settling cylinder 3, with the outer ring 9 and the dust settling cylinder 3 rotatably connected. A second nozzle 92 is provided at equal angles on the outer side of the outer ring 9, and the outer ring 9 is hollow. An inlet hole 91 is pre-reserved at equal angles on the side of the outer ring 9 near the dust settling cylinder 3. The outer ring 9 communicates with the interior of the second ring tube 8 through the inlet hole 91, connecting hole 31, and outlet hole 81. The connecting hole 31 is provided at equal angles on the outer wall of the dust settling cylinder 3, and the outlet hole 81 is provided at equal angles on the side of the second ring tube 8 that is in contact with the dust settling cylinder 3. The second ring tube 8 is fixed to the inner wall of the dust settling cylinder 3 and communicates with the first ring tube 5 through a connecting pipe 7. The outer ring 9 near the dust settling cylinder 3... One end of the connecting rod 10 is fixedly connected to the side of the connecting rod 10, and a movable groove 32 is provided on the dust collection cylinder 3 on the outer side of the connecting rod 10. The connecting rod 10 and the dust collection cylinder 3 form a sliding structure through the movable groove 32. The other end of the connecting rod 10 is fixed with an inner ring 11, which fits and rotates against the inner wall of the dust collection cylinder 3. The inner ring 11 is hollow, and a through fixing hole 111 is provided at equal angles on the upper part of the inner ring 11. The fixing hole 111 is connected to the connecting cover 12 through a through hole 33. The rotation angles of the inner ring 11 and the outer ring 9 are both less than 30°. The through hole 33 is provided at equal angles on the surface of the dust collection cylinder 3, and the connecting cover 12 is fixed at equal angles on the surface of the dust collection cylinder 3. The side of the connecting cover 12 is fixed with a... The outer ring 9 is connected to the jet pipe 13, and the end of the jet pipe 13 near the second nozzle 92 is inclined. When a larger spray area is required, the outer ring 9 is rotated so that the inlet hole 91, the connecting hole 31, and the outlet hole 81 coincide. In this way, part of the liquid in the first ring pipe 5 can be transferred to the second ring pipe 8 through the connecting pipe 7, and then transferred to the cavity of the outer ring 9 through the outlet hole 81, the connecting hole 31, and the inlet hole 91, and finally discharged from the second nozzle 92. Since the second nozzle 92 is inclined on the outer ring 9, the spray range can be expanded. When the outer ring 9 rotates, the inner ring 11 can be rotated synchronously through the connecting rod 10. When the connecting rod 10 rotates, it can slide in the movable groove 32. After rotation, the fixed hole 111 and the through hole 33 are connected. In this way, the wind force generated by the rotation of the fan blade 14 can be transmitted to the connecting cover 12 through the fixed hole 111 and the through hole 33, and finally enter the jet pipe 13 and be sprayed out. The sprayed gas blows directly onto the spray sprayed by the second nozzle 92, so that the water mist sprayed from the second nozzle 92 can be distributed more widely. Therefore, based on the change of the spray angle of the dust suppression cylinder 3, a large-scale dust suppression is further achieved. When a large-scale dust suppression is not needed, the outer ring 9 is rotated in the opposite direction to drive the inner ring 11 to rotate, so that the liquid inlet hole 91 and the connecting hole 31 are staggered, and the fixed hole 111 and the through hole 33 are staggered. In this way, the liquid and gas can only be discharged from the end of the dust suppression cylinder 3, achieving a small-scale dust suppression.

[0038] Example 2: Existing dust suppression machines have limited spraying distance, making it inconvenient to adjust the spray distance according to construction needs. Therefore, this example uses the following technical solution, such as... Figures 2-3 As shown, a distance adjustment mechanism is provided at one end of the dust collection cylinder 3 near the fan blade 14. The distance adjustment mechanism is used to adjust the spray distance and includes a fixed plate 15 fixed to the inner wall of the dust collection cylinder 3. The surface of the fixed plate 15 is evenly provided with holes. A movable plate 16 is attached to the side of the fixed plate 15. Both the fixed plate 15 and the movable plate 16 are fan-shaped structures with equal angles. The interior of the movable plate 16 is fixedly connected to the worm gear shaft of the worm gear mechanism 17. The worm gear shaft of the worm gear mechanism 17 is also fixedly connected to the fixed plate 16. An adjusting rod 18 is fixed and rotates through the dust collection cylinder 3. When the adjusting rod 18 is rotated, the movable plate 16 is driven to rotate through the meshing transmission of the worm gear mechanism 17. By changing the overlap range between the movable plate 16 and the fixed plate 15, the air volume blown towards the nozzle is adjusted. When the movable plate 16 and the fixed plate 15 are completely intersected, the gas is discharged from the holes on the fixed plate 15, and the air volume is the smallest at this time. When the movable plate 16 and the fixed plate 15 are completely overlapped, the air volume is the largest. The spray distance can be adjusted according to the air volume.

[0039] Example 3: During the spraying process of existing dust suppression machines, a large amount of liquid drips near the machine, causing not only ground dampness but also wasting water resources. Therefore, this example addresses this issue by implementing the following technical solution: Figure 4 and Figure 10 As shown, a recycling mechanism is provided on the side of the water storage base 1. The recycling mechanism is used to collect the liquid dripping during spraying. The recycling mechanism includes a sleeve plate 19 fixed to the water storage base 1. A connecting plate 20 passes through the end of the sleeve plate 19 away from the water storage base 1. The connecting plate 20 and the sleeve plate 19 are slidably connected, and both have arc-shaped cross-sections. The bottom edge of the sleeve plate 19 is flush with the lowest point of the return channel 21. The sleeve plate 19 is connected to the interior of the water storage base 1 through the return channel 21. During spraying, liquid drips near the water storage base 1. The connecting plate 20, which is stored in the sleeve plate 19, is pulled out. In this way, the dripping liquid can fall on the connecting plate 20 and the sleeve plate 19, and then flow along their slopes through the return channel 21 into the interior of the water storage base 1, thus recycling some water resources and reducing resource waste.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
