Description

Technical Field

[0001] This utility model relates to the field of water mist dust suppression technology, and in particular to a dust suppression device for highway construction. Background Technology

[0002] Water mist dust suppression devices for construction sites are environmental protection equipment specifically designed for construction sites. Their main function is to adsorb dust particles in the air by generating fine water mist particles, thereby reducing dust pollution at the construction site. They typically consist of a water supply system, atomization system, control system, and installation structure, and have advantages such as high efficiency in dust suppression, water conservation, convenient operation, and strong adaptability.

[0003] The applicant found through a search that a Chinese patent discloses "a water mist dust suppression device" with publication (announcement) number "CN219073505U". This patent mainly uses a funnel to screen fine stone particles and dust into the dust collection chamber, and then wets them through an atomizer to achieve dust removal while collecting and processing fine stone particles and dust. However, it does not have the function of rotating and spraying water mist, and cannot make the water mist more evenly distributed to achieve a better dust removal effect. Therefore, we propose a dust suppression device for highway construction. Utility Model Content

[0004] The purpose of this utility model is to provide a dust suppression device for highway construction, so as to solve the problem mentioned in the background art that the water mist cannot be distributed more evenly to achieve a better dust removal effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for highway construction, comprising a first base and a rotating mechanism. The rotating mechanism includes a limiting member, the lower surface of which is fixedly connected to the first base, and a rotating shell is rotatably connected to its inner wall. A water inlet is provided on the right side of the rotating shell, and a water outlet is fixedly connected to its left side. A first partition, a second partition, a third partition, and a rotating rod are fixedly connected to its inner wall from right to left. A connecting sleeve is rotatably connected to the water inlet, and an atomizing gun is fixedly connected to the outer wall of the water outlet. A pressure relief inlet is provided near the center of the first partition.

[0006] As a preferred embodiment, a base plate is fixedly connected to the lower surface of the first base, and a second base is fixedly connected to the upper surface of the base plate near the right end, and a fixing block is fixedly connected to the upper surface of the base plate near the left end, with a reserved interface in the center of the fixing block.

[0007] As a preferred embodiment, the outer wall of the outlet pipe away from the rotating shell is inserted into the inner wall of the reserved interface. A power storage block is fixedly connected at the bottom between the first and second partitions, and a pressure relief ring is fixedly connected at its center. Power storage channels are passed through the first partition, the power storage block, and the second partition. A pressure relief groove is fixedly connected to the upper half of the inner wall of the pressure relief ring. A spring is fixedly connected to the left inner wall of the pressure relief groove. A pressure relief component is fixedly connected to the end of the spring away from the second partition. A pressure relief outlet is opened near the center of the second partition. The pressure relief outlet and the lower hollow part of the pressure relief ring are in the same position.

[0008] As a preferred embodiment, a rotating shaft is rotatably connected to the center of the side of the second partition away from the first partition, and a flow rectifier is fixedly connected to its bottom. A collar is sleeved on the outer wall of the rotating shaft and inserted into the inner wall of the third partition. Fan blades are fixedly connected to both ends of the collar. A fixed shaft is fixedly connected to the upper part of the side of the third partition away from the second partition, and a water outlet is opened at the same position as the pressure relief outlet. A reduction gear set is provided on the outer wall of the rotating shaft and the fixed shaft, on the left side of the third partition. A rotating rod is fixedly connected to the reduction end of the reduction gear set.

[0009] As a preferred embodiment, an anti-dry-rotation filtration mechanism is provided on the right side of the rotating mechanism. The anti-dry-rotation filtration mechanism includes a water tank and a filter cylinder. A water inlet is fixedly connected to the center of the top surface of the water tank, a water level gauge is fixedly connected to its front, and a water inlet pipe is fixedly connected to its left side near the bottom.

[0010] As a preferred embodiment, a valve is fixedly installed on the outer wall of the water inlet pipe near the water tank, and a water pump is threadedly connected to the bottom horizontal section of the water inlet pipe. The end of the water pump away from the water tank is inserted into the inner wall of the connecting sleeve. Both the upper and lower ends of the filter cylinder are threadedly connected to the water inlet pipe, and a primary filter screen is provided near the upper end of the filter cylinder, and a secondary filter screen is provided near the lower end of the filter cylinder.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the set rotating mechanism, the kinetic energy of water can be used to drive the fan blades to rotate rapidly by means of the energy storage channel and the rectifier, which in turn drives the reduction gear set to rotate. Through the reduction gear set, the rotating rod fixed at its end and the rotating shell fixedly connected to the rotating rod can rotate at a uniform and appropriate speed, thereby realizing uniform rotation of the water outlet pipe and the atomizing gun on it to spray dust. When the water pressure between the first partition and the second partition is too high, it will squeeze the pressure relief component and the spring, causing the pressure relief component to slide into the pressure relief groove. At this time, water can flow out through the pressure relief inlet, the lower cavity of the pressure relief ring and the pressure relief outlet to achieve the purpose of reducing and stabilizing the water pressure.

[0013] 2. With the anti-dry-running filtration mechanism and water level gauge, the remaining water level in the tank can be monitored at any time. This allows for timely opening of the water inlet to inject sufficient water for dust removal, preventing the water pump from running dry due to insufficient water in the tank and affecting its service life. The water valve controls the opening and closing of the water flow in the tank. The filter cartridge and its primary and secondary filters can filter impurities in the water, preventing damage to the water pump or clogging of the atomizing gun nozzle.

Detailed Implementation

[0023] 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.

[0024] Example 1:

[0025] Please see the appendix Figure 1 - Appendix Figure 7A dust suppression device for highway construction includes a first base 1 and a rotating mechanism 6. The rotating mechanism 6 includes a limiting member 601, the lower surface of which is fixedly connected to the first base 1, and a rotating shell 602 is rotatably connected to its inner wall. A water inlet 603 is provided on the right side of the rotating shell 602, and a water outlet pipe 624 is fixedly connected to its left side. From right to left, a first partition 605, a second partition 606, a third partition 607, and a rotating rod 608 are sequentially fixedly connected to the inner wall of the rotating shell 602. A connecting sleeve 604 is rotatably connected to the water inlet 603, and an atomizing gun 6 is fixedly connected to the outer wall of the water outlet pipe 624. 25. A pressure relief inlet 610 is provided near the center of the first partition 605. A base plate 2 is fixedly connected to the lower surface of the first base 1. A second base 3 is fixedly connected to the upper surface of the base plate 2 near the right end, and a fixing block 4 is fixedly connected to the upper surface of the base 3 near the left end. A reserved interface 5 is provided in the center of the fixing block 4. The outer wall of the end of the water outlet pipe 624 away from the rotating shell 602 is inserted into the inner wall of the reserved interface 5. A pressure storage block 611 is fixedly connected at the bottom between the first partition 605 and the second partition 606, and a pressure relief ring 612 is fixedly connected to its center. The first partition 605, the pressure storage block 611, and the pressure storage block 611 are all connected to the bottom of the first partition 605 and the second partition 606. A pressure storage channel 609 is passed through the block 611 and the second partition 606. A pressure relief groove 613 is fixedly connected to the upper half of the inner wall of the pressure relief ring 612. A spring 614 is fixedly connected to the left inner wall of the pressure relief groove 613. A pressure relief component 615 is fixedly connected to the end of the spring 614 away from the second partition 606. A pressure relief outlet 620 is opened near the center of the second partition 606. The pressure relief outlet 620 and the lower hollow part of the pressure relief ring 612 are in the same position. A rotating shaft 616 is rotatably connected to the center of the side of the second partition 606 away from the first partition 605, and its bottom... A rectifier 619 is fixedly connected to the rotating shaft 616. A collar 617 is sleeved on the outer wall of the rotating shaft 616 and inserted into the inner wall of the third partition 607. Fan blades 618 are fixedly connected to both ends of the collar 617. A fixed shaft 621 is fixedly connected to the upper part of the third partition 607 away from the second partition 606, and a water outlet 623 is opened at the same position as the pressure relief outlet 620. A reduction gear set 622 is provided on the outer wall of the rotating shaft 616 and the fixed shaft 621 and on the left side of the third partition 607. A rotating rod 608 is fixedly connected to the reduction end of the reduction gear set 622.

[0026] The fixing block 4 can provide support for the water outlet pipe 624 through the reserved interface 5. The outer wall of the rotating shell 602 is provided with a protruding ring in the middle, and the inner wall of the limiting member 601 is provided with a groove in the middle. The two can be fitted together, so that the rotating shell 602 can rotate within the limiting member 601, but cannot move horizontally. The fan blade 618, the reduction gear set 622 and the spring 614 are all made of plastic to adapt to the long-term immersion environment. The setting of the power storage channel 609 can increase the impact force of the water flow on the fan blade 618.

[0027] Specifically, the kinetic energy of water can be used to drive the fan blade 618 to rotate rapidly through the energy storage channel 609 and the rectifier 619, which in turn drives the reduction gear set 622 to rotate. The reduction gear set 622 causes the rotating rod 608 fixed at its end and the rotating shell 602 fixedly connected to the rotating rod 608 to rotate at a uniform and appropriate speed, so as to realize the uniform rotation of the water outlet pipe 624 and the atomizing gun 625 on it to spray dust. When the water pressure between the first partition 605 and the second partition 606 is too high, the pressure relief component 615 is slid into the pressure relief groove 613 by squeezing the pressure relief component 615 and the spring 614. At this time, water can flow out through the pressure relief inlet 610, the lower cavity 612 of the pressure relief ring and the pressure relief outlet 620 to reduce and stabilize the water pressure.

[0028] Example 2:

[0029] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 8 Furthermore, based on Embodiment 1, a dry-rotation-prevention filtration mechanism 7 is provided on the right side of the rotating mechanism 6. The dry-rotation-prevention filtration mechanism 7 includes a water tank 701 and a filter cylinder 706. A water inlet 702 is fixedly connected to the center of the top surface of the water tank 701, and a water level gauge 703 is fixedly connected to its front. An inlet pipe 704 is fixedly connected to its left side near the bottom. A valve 705 is fixedly installed on the outer wall of the inlet pipe 704 near the water tank 701. A water pump 709 is threadedly connected to the bottom horizontal section of the inlet pipe 704, and the end of the pump 709 away from the water tank 701 is inserted into the inner wall of the connecting sleeve 604. Both the upper and lower ends of the filter cylinder 706 are threadedly connected to the inlet pipe 704. A primary filter screen 707 is provided near its upper end, and a secondary filter screen 708 is provided near its lower end.

[0030] The vertical installation of the filter cartridge 706 allows for even distribution of water flow within the filter material, improving filtration efficiency. Both ends of the filter cartridge 706 are threadedly connected to the inlet pipe 704, facilitating filter cartridge replacement and aiding in the removal of sediment and impurities. The primary filter screen 707 uses a coarse mesh to filter larger particles, while the secondary filter screen 708 uses a fine mesh or filter cotton for fine filtration, enhancing filtration efficiency while minimizing impact on the water pump 709's water intake. Small holes are provided on the top surface of the water tank 701 and the top of the water level gauge 703, creating a communicating vessel to ensure identical water levels. The water level gauge 703 is made of transparent material and features graduations for easy monitoring of the remaining water in the water tank 701.

[0031] Specifically, the water level gauge 703 allows for real-time monitoring of the remaining water level in the water tank 701. Sufficient water for dust removal can be injected into the water tank 701 by opening the water inlet 702, preventing the water pump 709 from running dry and affecting its lifespan. The valve 705 controls the opening and closing of the water flow in the water tank 701. Impurities in the water are filtered through the filter cartridge 706 and its primary filter 707 and secondary filter 708, preventing damage to the water pump 709 or clogging of the nozzle of the atomizing gun 625.

[0032] Working principle of this utility model: This utility model is a dust suppression device for highway construction. When using this device for dust suppression, firstly, observe the remaining water level in the water tank 701 through the water level gauge 703. If it is insufficient, open the water inlet 702 to inject sufficient water. Then, assemble the water inlet pipe 704, filter cylinder 706, water pump 709, and rotating shell 602. Open the valve 705 and the water pump 709 to transport the filtered water through the water inlet pipe 704 to the inside of the rotating shell 602, located between the first partition 605 and the right side of the rotating shell 602. When the water pressure is low, the water enters between the second partition 606 and the third partition 607 through the energy storage channel 609. The rectifier 619 drives the fan blade 618 to rotate, thereby driving the reduction gear set 622 to work. This causes the rotating rod 608 fixed to the end of the reduction gear set 622 to drive the rotating shell 602 fixed thereto. 2. The device rotates at a uniform and appropriate speed, which eventually drives the water outlet pipe 624 fixed at the left end of the rotating shell 602 and the atomizing gun 625 on it to rotate at a uniform and appropriate speed, so that the water mist sprayed is more evenly distributed and the dust removal effect is more fully achieved. When the device is running, the water pressure in the space between the first partition 605 and the right side of the rotating shell 602 will continuously increase. When it reaches the predetermined value, it will squeeze the pressure relief component 615 to slide along the pressure relief groove 613 towards the second partition 606. At this time, the water flow can quickly flow out through the pressure relief inlet 610, the lower cavity 612 of the pressure relief ring and the pressure relief outlet 620 to reduce the water pressure and keep the water pressure stable. After use, close the valve 705 and wait for the water in the water inlet pipe 704 to be drained. Then turn off the water pump 709, remove the water inlet pipe 704, water pump 709, filter cartridge 706 and other components and transport them to the storage room for the next use.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
