Description

Technical Field

[0001] This utility model belongs to the field of dust suppression spraying technology, and in particular relates to a dust suppression spraying device based on a rotating mechanism. Background Technology

[0002] During industrial production, a large amount of dust is generated inside factory buildings due to material processing, loading and unloading operations. This dust not only causes wear and tear on production equipment, shortening its service life, but also harms workers' health, causing occupational diseases such as respiratory illnesses, and pollutes the surrounding environment. Therefore, installing sprinkler dust suppression devices fixed to the factory roof, which spray water mist into the factory to absorb dust, has become a common method of dust control.

[0003] Currently, existing dust suppression spraying devices are mainly fixed spraying structures, with nozzles fixedly installed at specific locations on the roof of the factory. They can only spray the area directly in front of the nozzles, resulting in a large number of blind spots for a single nozzle and a limited dust suppression coverage. Densely arranged spraying devices would increase installation and maintenance costs. Secondly, existing dust suppression spraying devices are fixed at high altitudes, requiring workers to use ladders, scaffolding, and other tools to climb and perform maintenance, which poses a risk of falling from heights. Moreover, the maintenance process is cumbersome and consumes a lot of manpower and time.

[0004] Therefore, it is essential to invent a dust suppression spray device based on a rotating mechanism. Utility Model Content

[0005] To address the above problems, this utility model proposes a dust suppression spraying device based on a rotating mechanism. The technical solution used is as follows:

[0006] A dust suppression spray device based on a rotating mechanism includes a mounting plate, a lifting mechanism, a limiting post, a connecting plate, a multi-channel rotary joint, an air inlet pipe, a liquid inlet pipe, a liquid delivery pipe, a gas delivery pipe, a two-fluid nozzle, and a limiting sleeve. The mounting plate is fixed to the top of the factory building by bolts, and the lifting mechanism is fixed to the lower side of the mounting plate by bolts. The limiting sleeve is fixed to the lower side of the lifting mechanism by bolts, and a limiting post is slidably arranged inside the limiting sleeve. The upper side of the limiting post is fixed to the output end of the lifting mechanism. The lower side of the limiting post... A connecting plate is fixed with bolts, and a multi-channel rotary joint is fixed to the lower side of the connecting plate with bolts. The input end of the multi-channel rotary joint is fixed to the air inlet pipe and the liquid inlet pipe respectively through connectors. The other end of the air inlet pipe is connected to an external air supply device, and the other end of the liquid inlet pipe is connected to an external liquid supply device. The output end of the multi-channel rotary joint is fixed to the liquid delivery pipe and the air delivery pipe respectively through connectors. The other ends of the liquid delivery pipe and the air delivery pipe are fixed to the corresponding input ends of the two-fluid nozzle, and both the liquid delivery pipe and the air delivery pipe are rigid pipes.

[0007] Furthermore, the lifting mechanism includes a housing, a rotating column, a take-up and release drum, a traction rope, a spring, and a locking mechanism. The housing is fixed to the lower side of the mounting plate by bolts, and the rotating column is rotatably mounted inside the housing via a support bearing. The take-up and release drum is fixed to the outer side of the rotating column by bolts, and the traction rope is wound around the outer side of the take-up and release drum. One end of the traction rope is fixed to the take-up and release drum, and the other end of the traction rope is fixed to the upper end of the limiting column. A limiting sleeve is fixed to the lower side of the housing by bolts. A spring is movably mounted inside the housing, with one end of the spring fixed to the rotating column and the other end fixed to the outer side of the rotating column. The inner wall of the shell is fixed; a locking mechanism is fixed to the outer shell by bolts, wherein the output end of the locking mechanism is fixed to the rotating column. With this configuration, the rotating column can be locked by the locking mechanism during normal use, so that the multi-channel rotary joint is located on the top of the building. When the multi-channel rotary joint needs to be repaired, the locking mechanism can be released from the rotating column, and the multi-channel rotary joint can be moved to the ground position by using a tool (such as a long hook). After the repair is completed, the multi-channel rotary joint can be reset by the cooperation of the spring, the winding drum and the traction rope.

[0008] Furthermore, the locking mechanism includes a rotating disk, a locking block, a sliding post, a compression spring, an adjusting rope, a first ring, an auxiliary plate, and a hook. The rotating disk is fixed to the outer side of the rotating post by bolts, and a locking block is provided on the lower side of the rotating disk, wherein the initial position of the locking block is fitted with the rotating disk. Several protrusions are evenly distributed on the outer side of the rotating disk, and a groove corresponding to the rotating disk is provided on the upper side of the locking block. Sliding posts are fixed to the lower sides of both ends of the locking block by bolts, wherein the sliding posts are slidably connected to the outer shell. A compression spring is fitted on the outer side of each sliding post. The compression springs are all located between the locking block and the outer shell. An adjusting rope is fixed to the lower side of the middle part of the locking block. The adjusting rope moves through the outer shell, and the other end of the adjusting rope is fixed to a first ring. The auxiliary plate is fixed to the lower side of the outer shell by bolts. A hook is fixed to the outer side of the auxiliary plate by bolts. The hook is located on the lower side of the first ring. This arrangement allows the rotating column to be locked during use. When needed, the first ring can be hooked onto the hook using a tool (such as a long hook) to lock the rotating column.

[0009] Furthermore, the multi-channel rotary joint includes a positioning cylinder, a rotating sleeve, a first circulation channel, a second circulation channel, a servo motor, and gears. The positioning cylinder is fixed to the lower side of the connecting plate by bolts, and the rotating sleeve is rotatably mounted on the outer side of the positioning cylinder via a sealed bearing. A first circulation channel and a second circulation channel are respectively formed between the rotating sleeve and the positioning cylinder. An air inlet pipe and a liquid inlet pipe are fixed inside the positioning cylinder, with the air inlet pipe communicating with the interior of the second circulation channel and the liquid inlet pipe communicating with the interior of the first circulation channel. Several [unclear - possibly referring to a specific type of fixture] are fixed on the outer side of the rotating sleeve. The device includes an infusion tube and several gas infusion tubes, with the infusion tubes all communicating with the interior of the first circulation channel and the gas infusion tubes all communicating with the interior of the second circulation channel. The servo motor is fixed to the connecting plate by bolts, and a gear is fixed to the output end of the servo motor. This gear meshes with the outer side of the rotating sleeve. This arrangement allows for the separate reception of liquid and gas delivered by the inlet pipe and the inlet pipe, and their separate delivery into the gas infusion tube and the infusion tube, respectively. The servo motor and the gear work together to move the two fluid nozzles accordingly, thereby uniformly spraying dust around the device.

[0010] Furthermore, the lower end of the positioning cylinder is fixed with a second ring body by bolts. This arrangement facilitates the pulling of the multi-channel rotary joint downward from the top of the building by means of a tool (such as a long hook) in cooperation with the second ring body.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The multi-channel rotary joint of this utility model has the following features: First, the circulating channel receives the liquid delivered by the inlet pipe and then transports it into the delivery pipe; second, the circulating channel receives the gas delivered by the inlet pipe and then transports it into the delivery pipe. Furthermore, during use, the servo motor and gears work together to rotate the rotating sleeve on the positioning cylinder, causing the two-fluid nozzles to move accordingly, thus uniformly spraying dust around the device. This not only effectively increases the dust suppression coverage area but also significantly reduces installation and maintenance costs compared to traditional dense nozzle arrangements.

[0013] 2. The lifting mechanism of this utility model can lock the rotating column through the locking mechanism during normal use, thereby keeping the multi-channel rotary joint at the top of the building. When maintenance is required, the locking mechanism can be released to move the multi-channel rotary joint to the ground position using a tool (such as a long hook). After maintenance is completed, the multi-channel rotary joint can be reset with the help of a spring, a winding drum, and a traction rope, effectively avoiding the risk of falling from a height and saving manpower and time costs.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Please see Figures 1 to 4 As shown, this utility model is a dust suppression spray device based on a rotating mechanism, including a mounting plate 1, a lifting mechanism 2, a limiting post 3, a connecting plate 4, a multi-channel rotary joint 5, an air inlet pipe 6, a liquid inlet pipe 7, a liquid delivery pipe 8, a gas delivery pipe 9, a two-fluid nozzle 10, and a limiting sleeve 11. The mounting plate 1 is fixed to the top of the factory building by bolts, and the lifting mechanism 2 is fixed to the lower side of the mounting plate 1 by bolts. The limiting sleeve 11 is fixed to the lower side of the lifting mechanism 2 by bolts, and the limiting post 3 is slidably arranged inside the limiting sleeve 11. The upper side of the limiting post 3 is fixed to the output end of the lifting mechanism 2. A connecting plate 4 is fixed to the lower side of the limiting post 3 by bolts, and a multi-channel rotary joint 5 is fixed to the lower side of the connecting plate 4 by bolts. The input end of the multi-channel rotary joint 5 is fixed to the air inlet pipe 6 and the liquid inlet pipe 7 by connectors respectively. The other end of the air inlet pipe 6 is connected to an external air supply device, and the other end of the liquid inlet pipe 7 is connected to an external liquid supply device. The output end of the multi-channel rotary joint 5 is fixed to the liquid delivery pipe 8 and the air delivery pipe 9 by connectors respectively. The other ends of the liquid delivery pipe 8 and the air delivery pipe 9 are fixed to the corresponding input ends of the two-fluid nozzle 10, and both the liquid delivery pipe 8 and the air delivery pipe 9 are rigid pipes.

[0024] Specifically, the lifting mechanism 2 includes a housing 21, a rotating column 22, a take-up and release drum 23, a traction rope 24, a spring 25, and a locking mechanism 26. The housing 21 is fixed to the lower side of the mounting plate 1 by bolts, and the rotating column 22 is rotatably mounted inside the housing 21 via a support bearing. The take-up and release drum 23 is fixed to the outer side of the rotating column 22 by bolts, and the traction rope 24 is wound around the outer side of the take-up and release drum 23. One end of the traction rope 24 is fixed to the take-up and release drum 23, and the other end of the traction rope 24 is fixed to the upper end of the limit post 3. A limit sleeve 11 is fixed to the lower side of the housing 21 by bolts. The spring 25 is movably arranged inside the housing 21, and one end of the spring 25 is fixed to the rotating column 22, and the other end of the spring 25 is fixed to the inner wall of the housing 21. The locking mechanism 26 is fixed to the housing 21 by bolts, and the output of the locking mechanism 26... The end is fixed to the rotating column 22. During normal use, the rotating column 22 can be locked by the locking mechanism 26. At this time, the tension of the traction rope 24 can fix the limiting column 3 inside the limiting sleeve 11. When the device needs to be repaired, the locking effect of the locking mechanism 26 on the rotating column 22 can be released. At this time, the staff can use tools (such as a long hook) to pull the multi-channel rotary joint 5 to the ground position (the winding drum 23 reduces the winding length of the traction rope 24, and the spring 25 is wound up and stores elastic potential energy). Thus, the multi-channel rotary joint 5 can be repaired without the staff having to climb up. After the repair is completed, the multi-channel rotary joint 5 can be released. At this time, the spring 25 will release the stored elastic potential energy, so that the winding drum 23 winds up the traction rope 24, thereby making the multi-channel rotary joint 5 reset.

[0025] Specifically, the locking mechanism 26 includes a rotating disk 261, a locking block 262, a sliding column 263, a compression spring 264, an adjusting rope 265, a first ring 266, an auxiliary plate 267, and a hook 268. The rotating disk 261 is fixed to the outer side of the rotating column 22 by bolts, and the locking block 262 is provided on the lower side of the rotating disk 261, wherein the initial position of the locking block 262 is fitted with the rotating disk 261. Several protrusions are evenly distributed on the outer side of the rotating disk 261, and the upper side of the locking block 262 is provided with a groove that is compatible with the rotating disk 261. The lower sides of both ends of the locking block 262 are fixed with sliding columns 263 by bolts, wherein the sliding columns 263 are slidably connected to the outer shell 21. The outer side of the sliding column 263 is fitted with a compression spring 264, wherein the compression spring 264 is disposed between the locking block 262 and the outer shell 21. An adjusting rope 265 is fixed to the lower side of the middle part of the locking block 262. The adjusting rope 265 moves through the outer shell 21, and the other end of the adjusting rope 265 is fixed to the first ring body 266. The auxiliary plate 267 is fixed to the lower side of the outer shell 21 by bolts. The outer side of the auxiliary plate 267 is fixed with a hook 268 by bolts. The hook 268 is located on the lower side of the first ring body 266. When in use, the locking block 262 can squeeze and limit the rotating disk 261 under the action of the compression spring 264, thereby preventing the rotating column 22 from rotating. Secondly, when it is necessary to release the lock on the rotating column 22, the first ring body 266 can be hung on the hook 268 by a tool (such as a long hook), and then the locking block 262 can be pulled by the adjusting rope 265, so that the locking block 262 is away from the rotating disk 261.

[0026] Specifically, the multi-channel rotary joint 5 includes a positioning cylinder 51, a rotating sleeve 52, a first circulation channel 53, a second circulation channel 54, a servo motor 55, and a gear 56. The positioning cylinder 51 is fixed to the lower side of the connecting plate 4 by bolts, and the rotating sleeve 52 is rotatably mounted on the outer side of the positioning cylinder 51 through a sealed bearing. The first circulation channel 53 and the second circulation channel 54 are respectively opened between the rotating sleeve 52 and the positioning cylinder 51. An air inlet pipe 6 and a liquid inlet pipe 7 are fixed inside the positioning cylinder 51, wherein the air inlet pipe 6 communicates with the interior of the second circulation channel 54, and the liquid inlet pipe 7 communicates with the interior of the first circulation channel 53. A plurality of liquid delivery pipes 8 and a plurality of air delivery pipes 9 are fixed on the outer side of the rotating sleeve 52, wherein all liquid delivery pipes 8 communicate with the interior of the first circulation channel 53, and all air delivery pipes 9 communicate with the interior of the second circulation channel 54. The two circulation channels 54 are internally connected; the servo motor 55 is fixed to the connecting plate 4 by bolts, and the output end of the servo motor 55 is fixed with a gear 56, which meshes with the outer side of the rotating sleeve 52; the servo motor 55 is electrically connected to an external control device through a data cable. In use, the first circulation channel 53 can receive the liquid delivered by the liquid inlet pipe 7 and then deliver it into the liquid delivery pipe 8. The second circulation channel 54 can receive the gas delivered by the air inlet pipe 6 and then deliver it into the air delivery pipe 9. Furthermore, in use, the servo motor 55 and the gear 56 can drive the rotating sleeve 52 to rotate on the positioning cylinder 51, thereby causing the two fluid nozzles 10 to move accordingly, and uniformly spray dust suppression treatment around the device.

[0027] Specifically, the lower end of the positioning cylinder 51 is fixed with a second ring 12 by bolts. This arrangement facilitates the pulling of the multi-channel rotary joint 5 from the top of the building by means of a tool (such as a long hook) in cooperation with the second ring 12.

[0028] Please see Figure 1-4 As shown, this utility model is a dust suppression spraying device based on a rotating mechanism, and its working principle is as follows:

[0029] In operation, liquid and gas can be supplied to the air inlet pipe 6 and liquid inlet pipe 7 via external air supply and liquid supply devices, respectively. The air inlet pipe 6 and liquid inlet pipe 7 then deliver the gas to the multi-channel rotary joint 5. The multi-channel rotary joint 5 then delivers the received liquid and gas to the two-fluid nozzle 10 via the liquid delivery pipe 8 and air delivery pipe 9, respectively. The two-fluid nozzle 10 mixes and sprays the liquid and gas. An external control device can activate a servo motor 55 to move the two-fluid nozzle 10 accordingly, thereby uniformly reducing dust around the device.

[0030] Secondly, when the multi-channel rotary joint 5 needs to be inspected, the working state of the lifting mechanism 2 can be adjusted, and the multi-channel rotary joint 5 can be pulled down from the top of the building by means of a tool (such as a long hook) in cooperation with the second ring body 12, so as to facilitate the inspection. After the inspection is completed, the multi-channel rotary joint 5 can be reset by means of the lifting mechanism 2.
