Description

Technical Field

[0001] This utility model relates to the technical field of water spraying and dust suppression devices, specifically a water spraying and dust suppression device for the production process of sand and gravel aggregates. Background Technology

[0002] As a fundamental and widely used raw material in infrastructure construction such as buildings and roads, sand and gravel aggregates generate a large amount of dust during their production process, including crushing, screening, conveying, and stockpiling. This dust not only severely pollutes the working environment but also endangers the respiratory health of operators.

[0003] A search revealed a utility model patent with patent authorization announcement number CN216677523U, which discloses a water spraying device for dust prevention during the production of sand and gravel aggregates. The device includes a water storage tank, a movable base frame, a lower sleeve, an upper sleeve, a main pipe, and a rotating pipe. The upper end of the lower sleeve is fixedly connected to the lower end of the upper sleeve. One end of the rotating pipe extends from the lower end of the lower sleeve to the upper part of the upper sleeve. A bearing is installed between the rotating pipe and the inner wall of the sleeve. A tee is installed at the upper end of the rotating pipe, and the rotating pipe is connected to the main pipe through the tee. A branch pipe is installed on the main pipe.

[0004] Currently, sand and gravel aggregate production lines generally use water spraying to suppress dust. Traditional dust suppression devices are mostly fixed spray systems, with fixed nozzle installation positions, limited spray range and angle, and obvious dust suppression dead zones. Although some mobile water trucks have appeared on the market, their functions are often relatively simple, and the spraying mode of the nozzles is usually fixed or can only be adjusted manually. They cannot achieve automated and three-dimensional spraying, and the dust suppression effect is limited. Utility Model Content

[0005] The purpose of this utility model is to provide a water spraying dust suppression device in the production process of sand and gravel aggregates, which solves the problem of limited dust suppression effect of existing water spraying dust suppression devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water spraying and dust suppression device for sand and gravel aggregate production, comprising a vehicle platform, with universal wheels installed at the four corners of the bottom of the vehicle platform, a water tank fixedly connected to the upper center of the vehicle platform, a hollow tube installed on the top of the water tank via a bearing, the hollow tube penetrating the water tank, a polygonal prism tube slidably connected inside the hollow tube, the polygonal prism tube penetrating the hollow tube, a horizontal pipe connected to the top of the polygonal prism tube, multiple nozzles arranged below the horizontal part of the horizontal pipe, a submersible pump fixedly installed on the inner bottom of the water tank, the output end of the submersible pump connected to the hollow tube, and a push frame welded to the upper right side of the vehicle platform.

[0007] Preferably, a sliding sleeve is fixedly connected to the lower section of the polygonal tube, the sliding sleeve being slidably connected to the inside of the hollow tube, and a sealing ring is embedded in the outer wall of the sliding sleeve, the sealing ring being slidably connected to the inside of the hollow tube. The sliding sleeve and sealing ring enhance the relative sealing between the polygonal tube and the hollow tube.

[0008] Preferably, a driven gear is fixedly connected to the upper section of the hollow tube, and a drive motor is fixedly installed on the top of the water tank. A drive gear is fixedly connected to the end of the output shaft of the drive motor, and the drive gear meshes with the driven gear. The drive motor drives the drive gear to rotate, and the drive gear, in turn, drives the hollow tube to rotate through its engagement with the driven gear. The hollow tube, by engaging with the outer contour of the polygonal prism tube, drives the polygonal prism tube and the horizontally placed tube to rotate horizontally.

[0009] Preferably, a fixing plate is fixedly connected to the middle section of the polygonal tube, the fixing plate is in contact with the top of the hollow tube, and a beveled ring is fixedly connected to the bottom of the fixing plate. A top rod is fixedly connected to the top left side of the water tank, the top of the top rod has an arc surface, and the arc surface of the top rod is in contact with the beveled part of the beveled ring. As the beveled ring rotates with the fixing plate, it can periodically receive an upward reaction force from the top rod, thereby allowing the polygonal tube to move up and down axially in the hollow tube.

[0010] Preferably, a raised ring is rotatably connected to the top of the water tank. Multiple fixing rings are fixedly connected to the upper end of the raised ring and the bottom of the fixing plate. Hooks are attached to adjacent fixing rings, and an elastic band is fixedly connected between the two hooks. The combination of the hooks with elastic bands and the fixing rings assists in the axial expansion and contraction of the fixing plate and the polygonal tube within the hollow tube, thus providing a restorative function.

[0011] Preferably, a corrugated sleeve is fixedly connected to the bottom edge of the fixing plate, and the bottom of the corrugated sleeve contacts the top of the water tank. The corrugated sleeve provides dust protection for the driven gear, drive motor, and drive gear.

[0012] Preferably, a water inlet pipe is fixedly connected to the upper left side of the water tank, and the water inlet pipe penetrates the water tank. A drain pipe is connected to the lower right side of the water tank. Both the water inlet pipe and the drain pipe are equipped with valves. The water inlet pipe and the drain pipe facilitate the addition and replacement of water in the water tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves a composite motion of horizontal rotation and periodic lifting of the nozzle by cooperating with the drive motor, gear set, top rod and inclined ring. This three-dimensional spraying mode expands the coverage of water mist and effectively improves the dust suppression effect in complex sand and gravel production sites. Compared with fixed spraying, it has higher dust removal efficiency.

[0014] 2. This utility model employs a sliding fit between a polygonal prism tube and a hollow tube, and incorporates a sliding sleeve, sealing ring, and dustproof corrugated sleeve at the telescopic parts to ensure the sealing and durability of the rotary lifting mechanism in dusty environments. Simultaneously, elastic bands and hooks provide auxiliary reset, making the structure operate more smoothly. Attached Figure Description

[0018] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 A dust suppression water spraying device for sand and gravel aggregate production includes a platform 1. Universal wheels 2 are installed at the four corners of the bottom of the platform 1. A water tank 3 is fixedly connected to the upper center of the platform 1. A hollow tube 4 is mounted on the top of the water tank 3 via a bearing, and the hollow tube 4 penetrates the water tank 3. A polygonal prism tube 5 is slidably connected inside the hollow tube 4, and the polygonal prism tube 5 penetrates the hollow tube 4. A horizontal pipe 6 is connected to the top of the polygonal prism tube 5. Multiple nozzles 7 are installed below the horizontal section of the horizontal pipe 6. A submersible pump 8 is fixedly installed at the bottom inner side of the water tank 3. The output end of the submersible pump 8 is connected to the hollow tube 4. A sliding sleeve 9 is fixedly connected to the lower section of the polygonal prism tube 5, and the sliding sleeve 9 is slidably connected to the inside of the hollow tube 4. A sealing ring 10 is embedded in the outer wall of the sliding sleeve 9, and the sealing ring 10 is slidably connected to the inside of the hollow tube 4. The sliding sleeve 9 and the sealing ring 10 increase the relative sealing between the polygonal prism tube 5 and the hollow tube 4.

[0019] Please see Figure 1 , Figure 4 A pusher 22 is welded to the upper right side of the vehicle plate 1. A water inlet pipe 23 is fixedly connected to the upper left side of the water tank 3, and the water inlet pipe 23 penetrates the water tank 3. A drain pipe 24 is connected to the lower right side of the water tank 3. Valves are installed on both the water inlet pipe 23 and the drain pipe 24. The installation of the water inlet pipe 23 and the drain pipe 24 facilitates the addition and replacement of water in the water tank 3.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6A driven gear 11 is fixedly connected to the upper section of the hollow tube 4. A drive motor 12 is fixedly installed on the top of the water tank 3. A drive gear 13 is fixedly connected to the end of the output shaft of the drive motor 12, and the drive gear 13 meshes with the driven gear 11. The drive motor 12 drives the drive gear 13 to rotate, and the drive gear 13 drives the hollow tube 4 to rotate through its engagement with the driven gear 11. The hollow tube 4, by engaging with the outer contour of the polygonal tube 5, drives the polygonal tube 5 and the horizontal tube 6 to rotate horizontally. A fixing plate 14 is fixedly connected to the middle section of the polygonal tube 5, and the fixing plate 14 contacts the top of the hollow tube 4. A beveled ring 15 is fixedly connected to the bottom of the fixing plate 14. A push rod 16 is fixedly connected to the top left side of the water tank 3. The top of the push rod 16 is provided with an arc surface, and the arc surface of the push rod 16 contacts the beveled part of the beveled ring 15. As the inclined ring 15 rotates with the fixed plate 14, it is periodically subjected to the upward reaction force of the push rod 16, thereby allowing the polygonal tube 5 to move axially up and down in the hollow tube 4. A raised ring 19 is rotatably connected to the top of the water tank 3. Multiple fixed rings 18 are fixedly connected to the upper end of the raised ring 19 and the bottom of the fixed plate 14. Hooks 20 are attached to adjacent fixed rings 18, and an elastic band 21 is fixedly connected between the two hooks 20. The cooperation between the hooks 20 with elastic bands 21 and the fixed rings 18 assists in the axial extension and retraction of the fixed plate 14 and the polygonal tube 5 in the hollow tube 4. A corrugated sleeve 17 is fixedly connected to the bottom edge of the fixed plate 14, with the bottom of the corrugated sleeve 17 contacting the top of the water tank 3. The corrugated sleeve 17 provides dust protection for the driven gear 11, drive motor 12, and drive gear 13.

[0021] The specific implementation process of this utility model is as follows: During use, the operator moves the entire device to the vicinity of the dust-generating point of the sand and gravel aggregate production line by holding the push frame 22 and using the universal wheels 2 at the bottom of the vehicle platform 1. Water is added to the water tank 3 through the water inlet pipe 23, and then the valve is closed. The device is then powered on, and the submersible pump 8 and drive motor 12 are started. The submersible pump 8 pumps water from the water tank 3 into the hollow tube 4 from its output end. The water flows sequentially through the hollow tube 4, the polygonal prism tube 5 sliding inside it, and the horizontal pipe 6 connected to it, finally spraying out as a water mist from multiple nozzles 7. Simultaneously, the drive motor 12 begins to rotate, driving the drive gear 13 on its output shaft to rotate. The drive gear 13 meshes with the driven gear 11 fixed on the hollow tube 4, thereby causing the hollow tube 4 to rotate around its axis within the bearing. Furthermore, as the polygonal prism tube 5 rotates horizontally, the fixing plate 14 fixed on it also rotates. The inclined ring 15 at the bottom of the fixing plate 14... The nozzle 7 will continuously contact the arc-shaped surface at the top of the push rod 16 fixed to the top of the water tank 3. When the inclined portion of the inclined ring 15 slides past the top of the push rod 16, the push rod 16 will generate an upward thrust on the inclined ring 15. This thrust is transmitted to the polygonal tube 5 through the fixing plate 14, forcing the polygonal tube 5 to overcome the tension of the elastic band 21 and slide upward along the inner wall of the hollow tube 4, thereby raising the height of the nozzle 7. When the inclined ring 15 passes the highest point of the push rod 16, the upward thrust disappears. At this time, the elastic band 21 connecting the fixing ring 18 on the convex ring 19 and the fixing ring 18 at the bottom of the fixing plate 14 begins to contract, providing a downward pull to assist the polygonal tube 5. The nozzle 7 assembly descends and resets smoothly. This process repeats itself as the nozzle 7 rotates horizontally, while simultaneously making up-and-down reciprocating movements, thereby covering a larger space volume and greatly increasing the contact probability between water mist and suspended dust. The dust suppression effect far exceeds that of fixed spray devices.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
