Description

Technical Field

[0001] The present invention relates to the technical field related to engineering construction, and in particular to a long-distance spray dust suppressor for engineering construction. Background Art

[0002] In engineering construction, dust reduction operations are indispensable. High-pressure atomization technology uses a spray dust suppressor to atomize water into tiny droplets, effectively absorbing dust particles in the air, thereby achieving efficient dust reduction. However, existing spray dust suppressors have some problems in practical applications. Most equipment relies on tap water as the water source for fog cannons, but these equipment generally lack tap water filtration functions. When larger particles of impurities in tap water enter the fog cannon, it is easy to cause the atomizing nozzle to be blocked, affecting the normal use of the equipment and causing a certain degree of inconvenience.

[0003] In order to overcome the above-mentioned defects, the prior art 1 (Announcement No. CN222765935U, Chinese Patent Announcement Date 2025.04.18) is a spray dust suppressor, which includes: a water tank and a fixed pipe, a top plate and a partition are fixedly connected inside the water tank respectively, one side of the top plate is fixedly connected to the partition, one side of the partition is provided with a mixing mechanism connected to the top plate, and a filtering mechanism is provided inside the water tank on the other side of the partition, the fixed pipe is fixedly installed to the middle of the bottom plate on one side of the water tank, the surface of the movable pipe is movably connected to the sleeve, the interior of the sleeve is connected to the movable pipe, and the surface of the fixed pipe is sleeved with an adjustment mechanism, the water tank is used to store water when the spray dust suppressor is used, and water source mixing is achieved inside the water tank, a filtering mechanism is provided to filter larger impurities in the water source, and a baffle is provided for cleaning after long-term use, and water source discharge is achieved through the cooperation of the fixed pipe and the movable pipe, the sleeve is provided to adjust the spraying angle, and the movable pipe is rotated to adjust the spraying angle. The spraying range is adjusted to improve the convenience of using the spray dust suppressor. There is a second prior art (a Chinese patent with announcement number CN219580152U and announcement date of 2023.08.25). A spray dust suppressor comprises a movable seat, a shell is fixedly connected to the top of the movable seat, a spray mechanism is fixedly connected to the top of the shell, a filtering mechanism is arranged inside the shell, a water inlet pipe is fixedly connected to the left side of the shell, and a handle is fixedly connected to the top of the movable seat. By setting the spray mechanism, during use, the flow of water is utilized to drive the rotation of the two-way sprinkler head, thereby reducing the use of the servo motor, thereby greatly reducing energy consumption, making the dust suppressor more suitable for use on construction sites, and having good practicality. The water entering the spray mechanism can be filtered through the filter net, and the debris in the water can be removed, thereby avoiding the blockage of the spray component caused by debris, and ensuring the dust reduction efficiency of the dust suppressor.

[0004] Although the existing technology filters water through a filtering mechanism, the structure of the filtering mechanism is relatively complex, which can easily lead to increased production and maintenance costs. In addition, the power to drive the nozzle to rotate through pipes or water flow is insufficient, which may lead to a reduction in the dust reduction range, thereby affecting the overall dust reduction effect.

[0005] In response to the above problems, it is urgent to carry out innovative design based on the original long-distance spray dust suppression machine for engineering construction. Therefore, we proposed that the long-distance spray dust suppression machine for engineering construction can well solve the above problems. Summary of the Invention

The specific contents are as follows:

[0017] (1) The swing of the protective tube can expand the spray coverage of the nozzle, improve the comprehensiveness of dust reduction, and reduce the problem of reduced dust reduction efficiency caused by insufficient driving force. The cooperation of the first magnetic block and the second magnetic block drives the filter plate to vibrate on the spring, thereby reducing the overall labor maintenance cost and time.

[0019] (3) When the bump continues to rotate away from the surface of the first airbag, the second torsion spring outside the rotating shaft rebounds to restore its initial position, and the gas inside the second airbag flows back into the first airbag, thereby realizing automatic reset of the nozzle rotation and improving the service life of the nozzle.

[0020] (4) The heat outside the second motor is transferred to the cavity of the friction ring, and the heat inside the friction block is transferred to the second auxiliary cylinder through the cavity, which reduces the inconvenience of rapid condensation of water mist after the nozzle is sprayed due to low ambient temperature, and ensures that the water mist can still effectively diffuse and reduce dust in a low temperature environment.

[0021] (5) Cold gas is introduced into the interior of the first auxiliary cylinder through an external pipe. The cold gas absorbs the heat generated by the rotation of the second motor through the first auxiliary cylinder and is transported to the second auxiliary cylinder through the cavity of the friction ring, thereby reducing the problem of rapid evaporation of water mist sprayed from the nozzle, which leads to reduced dust reduction efficiency.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1: In this embodiment, the first magnetic block 12 and the second magnetic block 13 cooperate to drive the filter plate 2 to vibrate on the spring 3, thereby accelerating the overall cleaning efficiency. Figure 1-Figure 3The technical solution shown in the figure includes a water tank 1, a filter plate 2 is connected to the inside of the water tank 1 through a spring 3, a first motor 4 is provided inside the water tank 1, a first output end of the first motor 4 is connected to a rotating assembly, a rotating seat 9 is connected to the rotating assembly, a protective cylinder 10 is provided on the rotating seat 9, a cleaning plate 11 is connected to the second output end of the first motor 4, the cleaning plate 11 is located on the surface of the filter plate 2, a first magnetic block 12 is provided at the bottom of the cleaning plate 11, a second magnetic block 13 is installed on the filter plate 2, the first magnetic block 12 is adapted to the second magnetic block 13, the water tank 1 is connected to a delivery pipe 14 through a water pump, the delivery pipe 14 is connected to a nozzle 18 through a transmission assembly, and the rotating assembly includes a semi-circular shaped body installed at the first output end of the first motor 4. The gear 5 and the side end of the half gear 5 are meshed and connected with the full gear 6, and the full gear 6 is connected with a rotating rod 7 inside. The outside of the rotating rod 7 is provided with a first torsion spring 8 for rebound. The end of the rotating rod 7 is connected to the bottom of the rotating seat 9 to introduce the required water source into the water tank 1. At this time, the introduced clean water passes through the filter plate 2 for filtering operation. The filter plate 2 is installed in the water tank 1 through the spring 3. When water flows through, the filter plate 2 will shake through the spring 3 under the action of the water flow, thereby improving the filtering efficiency and ensuring the clean quality of the subsequent spray water. Turn on the first motor 4, and the output end of the first motor 4 drives the half gear 5 to rotate, so that the full gear 6 at the side end of the half gear 5 rotates, which is convenient for the full gear 6 to drive the rotating rod 7 in the middle to rotate. The rotating seat 9 on the rotating rod 7 rotates, which facilitates the angle rotation of the protective tube 10 on the rotating seat 9. Since the first torsion spring 8 is provided on the outside of the rotating rod 7, when the half gear 5 continues to rotate away from the surface of the full gear 6, the rotating rod 7 rebounds through the first torsion spring 8, and the rotating rod 7 drives the upper end rotating seat 9 to restore the initial position, so that the protective tube 10 on the rotating seat 9 swings repeatedly. The swing of the protective tube 10 can expand the spray coverage of the nozzle 18, improve the comprehensiveness of dust reduction, and reduce the problem of reduced dust reduction efficiency due to insufficient driving force. Turn on the water pump inside the water tank 1, and the water pump delivers the filtered clean water to the nozzle 18 through the delivery pipe 14 for spraying. When the first motor 4 is in use, the first motor The second output end of 4 drives the cleaning plate 11 to rotate, so that the cleaning plate 11 can clean the impurities on the filter plate 2. Since the first magnetic block 12 at the bottom of the cleaning plate 11 is adapted to the second magnetic block 13 on the filter plate 2, the first magnetic block 12 and the second magnetic block 13 are matched to drive the filter plate 2 to shake on the spring 3, thereby accelerating the overall cleaning efficiency, reducing the overall labor maintenance cost and time, and ensuring the continuous and stable operation of the filtration system. The clean water is introduced into the first sleeve 15 and transported to the delivery chamber 16 through the first sleeve 15. The clean water in the delivery chamber 16 is transmitted through the second sleeve 17 and transported to the nozzle 18 through the annular delivery pipe 14 on the second sleeve 17 for spraying, thereby improving the overall dust reduction effect.

[0036] Embodiment 2: In this embodiment, the nozzle 18 rotates on the rotating shaft 25. The rotation of the nozzle 18 makes the water mist distribution more uniform and enhances the dust reduction effect. Figure 4-Figure 9 As shown, it is disclosed that: a second motor 19 is provided inside the protective tube 10, a rotating shaft 20 is connected to the output end of the second motor 19, a fan 21 is installed on the outside of the rotating shaft 20, and a transmission component includes a first sleeve 15 installed at the end of the conveying pipe 14, the first sleeve 15 is installed on the outside of the rotating shaft 20, a conveying cavity 16 is opened inside the rotating shaft 20, the inner cavity of the first sleeve 15 is connected to the conveying cavity 16, the conveying cavity 16 is connected to the inner cavity of the second sleeve 17, the second sleeve 17 is installed on the outside of the rotating shaft 20, a protrusion 22 is installed on the outside of the rotating shaft 20, a first airbag 23 is provided on the outside of the rotating shaft 20, the protrusion 22 contacts the first airbag 23 after rotation, the first airbag 23 is connected to the second airbag 24 through a pipeline, the second airbag 24 is provided on the side end of the nozzle 18, a rotating shaft 25 is provided on the side end of the nozzle 18, a second torsion spring 26 is installed on the outside of the rotating shaft 25, open the second motor 19, the second The output end of the motor 19 drives the rotating shaft 20 to rotate, which facilitates the rotation of the fan 21 outside the rotating shaft 20, thereby increasing the range of the water mist sprayed by the nozzle 18 and effectively improving the effective area of ​​dust reduction. When the rotating shaft 20 rotates, the protrusion 22 on its outside squeezes the first airbag 23, so that the gas inside the first airbag 23 is transported to the second airbag 24. The second airbag 24 squeezes the nozzle 18, so that the nozzle 18 rotates on the rotating shaft 25. Through the rotation of the nozzle 18, the water mist is distributed more evenly, and the dust reduction effect is enhanced. Since a second torsion spring 26 is provided on the outside of the rotating shaft 25, when the protrusion 22 continues to rotate away from the surface of the first airbag 23, the second torsion spring 26 on the outside of the rotating shaft 25 rebounds to restore its initial position, and the gas inside the second airbag 24 flows back to the inside of the first airbag 23, thereby realizing the automatic resetting of the rotation of the nozzle 18 and improving the service life of the nozzle 18.

[0037] Embodiment 3: In this embodiment, the heat inside the friction block 29 is transferred to the second auxiliary cylinder 32 through the cavity 30, which reduces the inconvenience of the water mist condensing quickly after the spray head 18 is sprayed due to the low ambient temperature. Figure 10 and Figure 11As shown, it is disclosed that: a screw 27 is connected through the protective cylinder 10, a friction ring 28 is provided at the end of the screw 27, a friction block 29 adapted to the friction ring 28 is provided on the outside of the rotating shaft 20, a cavity 30 is provided inside the friction ring 28, and the cavity 30 is connected to the inner cavity of the first auxiliary cylinder 31 and the second auxiliary cylinder 32 through a pipe.

A vent is provided on the surface of the second auxiliary cylinder 32, and the friction ring is fixed by the screw 27. 28 is raised and lowered. When the friction ring 28 moves to the surface of the friction block 29, the friction block 29 on the outside of the rotating shaft 20 rotates inside the friction ring 28, generating heat by friction, which facilitates the increase of the temperature of the clean water transported through the inside of the rotating shaft 20. At this time, the heat inside the friction block 29 is transported to the second auxiliary cylinder 32 through the cavity 30, reducing the inconvenience of the water mist quickly condensing after the nozzle 18 is sprayed due to the low ambient temperature, ensuring that the water mist can still effectively diffuse and reduce dust in a low temperature environment, and at this time the first auxiliary cylinder 31 is connected to the air outlet. The gas transports the heat generated when the second motor 19 rotates, facilitating the heat transfer from the outside of the second motor 19 to the cavity 30 of the friction ring 28, facilitating effective temperature transfer, making full use of the heat generated by the operation of the equipment, and realizing the rational use of energy. When the ambient temperature is high, the friction ring 28 is moved upward by the screw 27, so that the friction ring 28 leaves the surface of the friction block 29. The first auxiliary cylinder 31 provided can be connected to an external pipeline, and cold gas is introduced into the first auxiliary cylinder 31 through the external pipeline. The cold gas absorbs the heat generated when the second motor 19 rotates through the first auxiliary cylinder 31, and the gas is transported to the cavity 30 of the friction ring 28 through the second motor 19, and then transported to the second auxiliary cylinder 32 through the cavity 30 of the friction ring 28, and ejected from the vent on the surface of the second auxiliary cylinder 32, thereby reducing the problem of reduced dust reduction efficiency caused by rapid evaporation of water mist sprayed from the nozzle 18, effectively coping with different ambient temperatures, and ensuring that the device can maintain good dust reduction performance under various climatic conditions.
