[0030] This embodiment provides a bleaching powder dosing device to solve the problem that a large amount of bleaching powder dust generated during the disinfection and application of bleaching powder in filter sand can cause toxicity to the human body through the upper respiratory tract and skin mucous membranes.

[0031] Specifically, such as Figures 1 to 2 As shown, a bleaching powder dosing device includes a positioning and fastening structure 1 and a spraying structure 2. The positioning and fastening structure 1 is used to fix the bleaching powder tank 10. The spraying structure 2 includes a high-pressure pump (not shown in the figure), a dispensing pipe 21, a water dispensing pipe 22, and a nozzle 23. The inlet of the high-pressure pump is used to connect to a water supply source, and the outlet of the high-pressure pump is connected to one end of the water dispensing pipe 22. The other end of the water dispensing pipe 22 is connected to the nozzle 23. The nozzle 23 is located at one end of the dispensing pipe 21, and the other end of the dispensing pipe 21 is connected to the bleaching powder tank 10. One end of the dispensing pipe 21 is used to add bleaching powder. Bleaching powder flows out through the outlet pipe 21, and a nozzle 23 is installed at the end of the outlet pipe 21 where the bleaching powder flows out. The nozzle 23 sprays water sucked up by the high-pressure pump in the form of a mist. The mist of high-pressure water presses down and mixes with the bleaching powder to dissolve the bleaching powder dust, thereby preventing the bleaching powder dust from flying everywhere and avoiding the problem of bleaching powder dust causing harm to the human body through the upper respiratory tract and skin mucous membranes.

[0032] Optionally, the number of nozzles 23 is at least two, and the at least two nozzles 23 are evenly distributed around the circumference of the dispensing pipe 21. At least two nozzles 23 are evenly distributed around the circumference of the dispensing pipe 21 at the end where the bleaching powder is sprayed, so that the mist of water sprayed from the nozzles 23 can evenly cover the bleaching powder sprayed from the dispensing pipe 21, allowing the mist of water to fully mix and dissolve the bleaching powder dust, thereby further preventing the bleaching powder dust from flying everywhere. In this embodiment, the number of nozzles 23 is four; in other embodiments, the number of nozzles 23 can be two, three, or six, etc.

[0033] Optionally, the bleaching powder dosing device also includes a transfer vehicle 3, which includes a frame 31 and a positioning and fastening structure 1 mounted on the frame 31. The positioning and fastening structure 1 fixes the bleaching powder bucket 10, meaning that the bleaching powder bucket 10 is placed on the frame 31, and the movement of the transfer vehicle 3 causes the bleaching powder bucket 10 to move, making the rotation of the bleaching powder bucket 10 more convenient.

[0034] Furthermore, the transfer vehicle 3 also includes wheels 32 and a transfer drive component (not shown in the figure). The fixed end of the transfer drive component is fixedly connected to the frame 31, and the driving end of the transfer drive component is driven to the wheels 32. The transfer drive component drives the wheels 32 to roll, thereby moving the transfer drive component and the frame 31, thus realizing the forward or backward movement of the transfer vehicle 3.

[0035] Optionally, the transfer vehicle 3 is also equipped with a transfer control switch, which is used to control the power supply 33 to provide power to the transfer drive component.

[0036] Optionally, the bleaching powder bucket 10 dispensing device further includes a rotating structure 4, which includes a rotating drive component 41. The positioning and fastening structure 1 includes a bleaching powder bucket fixing frame 11, in which the bleaching powder bucket 10 can be fixed. The rotating drive component 41 is drivenly connected to the bleaching powder bucket fixing frame 11. The rotating drive component 41 drives the bleaching powder bucket fixing frame 11 to rotate about a first axis, which is parallel to the bottom of the bleaching powder bucket 10. The rotation of the bleaching powder bucket fixing frame 11 around the first axis drives the bleaching powder bucket 10 to rotate, thereby realizing the rotation of the bleaching powder bucket 10. This causes the opening of the bleaching powder bucket 10 to rotate downwards, thus achieving smooth outflow of bleaching powder. In this embodiment, the rotating drive component 41 is a forward and reverse speed-regulating motor. In other embodiments, the rotating drive component 41 can also be a forward and reverse constant speed motor or a servo motor, etc.

[0037] Furthermore, the rotating structure 4 also includes a geared motor 42. The input end of the geared motor 42 is connected to the drive end of the rotating drive component 41, and the output end of the geared motor 42 is connected to the bleaching powder bucket fixing frame 11. The geared motor 42 is used to reduce the driving force of the rotating drive component 41, so that the rotation angle and rotation speed of the bleaching powder bucket fixing frame 11 are kept within a controllable range. This prevents the bleaching powder bucket fixing frame 11 from rotating too fast or at too large an angle, which would be detrimental to the outflow of bleaching powder.

[0038] Optionally, the rotation structure 4 further includes a rotation control switch and a rotation controller. The rotation control switch is signal-connected to the rotation controller. The rotation control switch is used to control the power supply 33 to provide power to the rotation controller, and the rotation controller is used to control the rotation angle of the bleaching powder bucket fixing frame 11 and the bleaching powder bucket 10. It should be noted that the specific control methods of the rotation control switch and the rotation controller are existing technologies in the art and will not be described in detail here. Further, the bleaching powder dosing device also includes a lifting structure. The lifting structure 5 includes a positioning and fastening bracket 52 and a lifting transmission assembly 54. The output end of the lifting transmission assembly 54 is drivenly connected to the fixed end of the positioning and fastening bracket 52. The lifting transmission assembly 54 can drive the rotation drive component 41 and the bleaching powder bucket fixing frame 11 to move back and forth in the vertical direction, realizing the lifting and lowering of the bleaching powder bucket fixing frame 11 and the bleaching powder bucket 10, avoiding the bleaching powder bucket fixing frame 11 being too close to the frame 31, which would cause the frame 31 to interfere with and affect the rotation of the bleaching powder bucket 10. In this embodiment, the lifting drive component 54 is a hydraulic motor. In other embodiments, the lifting drive component 54 can be a hydraulic cylinder.

[0039] Furthermore, the lifting structure 5 also includes a lifting drive component 51 and a lifting bracket 53. The lifting transmission assembly 54 includes a lifting chain 542. The fixed end of the rotating drive component 41 is mounted on the positioning and fastening bracket 52. The lifting bracket 53 is fixedly connected to the frame 31. One end of the positioning and fastening bracket 52 and the lifting bracket 53 are fixedly connected. The other end of the lifting bracket 53 is connected to the output end of the lifting drive component 51 through the lifting chain 542. The positioning and fastening bracket 52 is provided with a fixing pin, and the lifting bracket 53 is provided with a fixing hole. The fixing pin is inserted into the fixing hole. The lifting chain 542 drives the lifting bracket 53 to extend vertically through the telescopic movement of the lifting drive component 51, thereby realizing the reciprocating movement of the bleaching powder bucket fixing frame 11 and the bleaching powder bucket 10 in the vertical direction. In other embodiments, the positioning and fastening bracket 52 may be provided with a fixing hole, and the lifting bracket 53 may be provided with a fixing pin.

[0040] Optionally, the lifting transmission assembly 54 also includes a lifting shaft 541, a gear 543, and a hydraulic rod (not shown in the figure). The lifting shaft 541 is welded to the end of the lifting bracket 53 facing away from the frame 31 in the vertical direction, and the axis of the lifting shaft 541 is parallel to the horizontal plane. The gear 543 is sleeved and rotatably connected to the lifting shaft 541. The gear 543 is meshed with the lifting chain 542. The first end of the lifting chain 542 is fastened to the positioning fastening bracket 52 by bolts. The second end of the lifting chain 542 is connected to the telescopic end of the hydraulic rod. The lifting transmission assembly 54 is extended and retracted by the lifting and lowering of the hydraulic rod. The hydraulic rod drives the second end of the lifting chain 542 to move back and forth in the vertical direction, so that the first end of the lifting chain 542 moves back and forth in the vertical direction, and the movement directions of the first end and the second end are opposite. This realizes that the hydraulic rod drives the positioning fastening bracket 52 to move back and forth in the vertical direction, thereby realizing the reciprocating movement of the bleaching powder bucket fixing frame 11 and the bleaching powder bucket 10 in the vertical direction. During the reciprocating movement of the positioning and fastening bracket 52 in the vertical direction, the gear 543, which meshes with the lifting chain 542, rotates on the lifting shaft 541, thus supporting the lifting chain 542.

[0041] Optionally, the lifting structure 5 also includes a lifting control switch and a lifting controller. The lifting control switch is signal-connected to the lifting controller. The lifting control switch controls the power supply 33 to provide power to the lifting controller, and the lifting controller controls the lifting height of the lifting structure 5, thereby controlling the lifting height of the bleaching powder bucket fixing frame 11 and the bleaching powder bucket 10. It should be noted that the specific control methods of the lifting control switch and the lifting controller are existing technologies in the field and will not be described in detail here.

[0042] Optionally, the transfer vehicle 3 is also equipped with a 220V / 50Hz mobile power supply 33, which provides power to the transfer drive, lifting drive 51 and rotation drive 41.

[0043] Optionally, the positioning and fastening structure 1 also includes a fixed seat 14, a positioning steel plate 12, and a connecting shaft 13. The fixed bearing seat 14 is connected to the positioning and fastening bracket 52. The positioning steel plate 12 is welded to the opposite sides of the bleaching powder bucket fixing frame 11. One end of the connecting shaft 13 is welded and fixed to the positioning steel plate 12. The rotating structure 4 includes a rotating drive component 41 and a reduction motor 42. The output shaft of the reduction motor 42 is connected to the inner ring of the rotating drive component 41, and the output shaft of the rotating drive component 41 is connected to the other end of the connecting shaft 13. The output shaft of the rotating drive component 41 drives the connecting shaft 13 to rotate, thereby realizing the stable rotation of the bleaching powder bucket fixing frame 11 and the bleaching powder bucket 10 driven by the connecting shaft 13. It should be noted that the reducer and the reduction motor 42 are commonly used mechanisms for changing the direction of the rotation axis in the prior art, and will not be described in detail here.

[0044] Optionally, the bleaching powder bucket fixing frame 11 includes side frames 111 and a door frame 112. Multiple side frames 111 are connected end-to-end to form a fixing area. The fixing area has an opening, and the door frame 112 is rotatably connected to the side frames 111 located at the opening to open or close the opening. The bleaching powder bucket 10 is placed within the fixing area, and the bleaching powder bucket 10 can be placed or removed by opening and closing the door frame 112. In this embodiment, there are three side frames 111. In other embodiments, the number of side frames 111 can be four, six, or seven, etc.

[0045] Furthermore, the bleaching powder bucket fixing frame 11 also includes a fixing ring 113, which is connected to the side frame 111. The fixing ring 113 has a notch that extends from the outer wall to the inner wall. The bleaching powder bucket 10 can be detachably engaged in the fixing ring 113 through the notch, thereby achieving positioning of the bleaching powder bucket 10 when it is flipped, and preventing the bleaching powder bucket 10 from shaking or even sliding out of the fixing frame when the bleaching powder bucket fixing frame 11 is rotated.

[0046] Optionally, such as Figure 3 As shown, the bleaching powder dosing device also includes a connecting structure 6, which includes a connecting pipe 61 and a control valve 62. The other end of the discharge pipe 21 is connected to the bleaching powder tank 10 through the connecting pipe 61. The inlet of the control valve 62 is connected to the bleaching powder tank 10, and the outlet of the control valve 62 is connected to the connecting pipe 61. The amount of bleaching powder dispensed is controlled by the control valve 62, thereby reducing the generation of bleaching powder dust and making the bleaching powder dissolve more fully in the mist water.

[0047] Furthermore, the connecting pipe 61 is configured as a telescopic hose, and the change in the length and angle of the telescopic hose makes it convenient for operators to adjust the dosing position of the bleaching powder.

[0048] Optionally, the connecting structure 6 also includes a first flange (not shown in the figure), a second flange 64, and a short pipe 63. The opening of the bleaching powder tank 10 is covered with a bleaching powder tank sealing cover 65, which has a through hole. One end of the bleaching powder tank sealing cover 65 and the short pipe 63 are both connected to the first flange, so that the through hole communicates with the short pipe 63 through the first flange. The other end of the short pipe 63 is connected to one end of the connecting pipe 61, and the other end of the connecting pipe 61 is connected to the other end of the dispensing pipe 21 through the second flange 64. This ensures that the entire process of adding bleaching powder is in a fully sealed state. Combined with the pressure water mist layer generated by the nozzle 23 at the end of the dispensing pipe 21 where the bleaching powder flows out, the bleaching powder dust is suppressed and dissolved, thereby solving the occupational health hazard problem of bleaching powder dust. This makes the bleaching powder adding device provided in this embodiment fully comply with the teaching, reform, water, sealing, protection, management, and inspection policy for dust prevention and maintenance.

[0049] The design and successful application of the bleaching powder dosing device in water treatment processes have saved manpower and resources for enterprise operators, solved the hazards of adding disinfectants to workers, and addressed occupational health protection issues. It has achieved the goal of occupational health protection, making the working environment suitable for workers and promoting and protecting their physical and mental health during occupational activities.
