DETAILED DESCRIPTION

[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, in the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0041] The utility model provides a medium pressure ultraviolet sterilizer which is easy to disassemble. Figure 1 To the attached Figure 5It can be seen that a medium-pressure ultraviolet sterilizer that is easy to disassemble mainly includes the following parts or components: a disinfection box 10, a guide plate 11, an ultraviolet lamp 13, a stirring shaft 14, and a lifting assembly 30.

[0042] In the present invention, the disinfection box 10 is provided with a liquid inlet pipe 101 and a liquid outlet pipe 103. The liquid inlet pipe 101 is connected to the end of the water inlet pipe 102 through a first quick-release assembly 50, and the liquid outlet pipe 103 is connected to the end of the water outlet pipe 104 through a second quick-release assembly 50; the guide plate 11 is arranged in the disinfection box 10, and the disinfection box 10 is divided from top to bottom into a filter chamber and a disinfection chamber. The first end of the guide plate 11 is connected to the first side of the disinfection box 10, and a water outlet 111 is provided between the second end of the guide plate 11 and the second side of the disinfection box 10. The liquid outlet pipe 103 is connected to the filter chamber and the disinfection chamber. A filter assembly is arranged on the first side surface of the disinfection chamber; a plurality of groups of ultraviolet lamps 13 are fixedly arranged in parallel and at intervals in the disinfection chamber below the guide plate 11; a plurality of stirring shafts 14 are arranged in the disinfection chamber, and each stirring shaft 14 is arranged between every two groups of ultraviolet lamps 13, and a stirring blade 141 is provided on the stirring shaft 14, and the plurality of stirring shafts 14 rotate alternately forward and reverse under the drive of the driving assembly 20; the lifting assembly 30 is connected to the plurality of stirring shafts 14, driving the plurality of stirring shafts 14 to rise and fall synchronously, and the stirring shafts 14 always rotate when rising and falling.

[0043] Water enters the disinfection box 10 from the water inlet pipe 102, the first quick-release component 50, and the liquid inlet pipe 101. After being filtered by the filter component, the water flows from the guide plate 11 to the water outlet 111, and falls into the disinfection chamber from the water outlet 111. Subsequently, the driving component 20 drives the multiple stirring shafts 14 to rotate alternately forward and reverse, and the stirring blades 141 stir the filtered water. The lifting component 30 drives the stirring shaft 14 to rise and fall, thereby increasing the degree of water interaction, and the rotating water can be in more complete contact with the ultraviolet lamp 13, which can effectively enhance the sterilization effect of the ultraviolet lamp 13 on deeper water.

[0044] Specifically, the guide plate 11 is tilted, with the first end being the higher end and the second end being the lower end, so that the filtered water can flow quickly from the water outlet 111 to the disinfection chamber.

[0045] As an embodiment, Figure 2As can be seen, a base plate 12 is provided below the bottom of the disinfection chamber, forming an equipment chamber between the base plate 12 and the bottom of the disinfection chamber. The drive assembly 20 includes a first motor 21 disposed within the equipment chamber, on which a wheel disc 22 is fixedly mounted. A first rack 23 is horizontally disposed on a slide rail within the equipment chamber, and a long slot 231 fixedly disposed at the end of the first rack 23 is slidably connected to an eccentrically disposed guide shaft 221 on the wheel disc 22. A plurality of rotating sleeves 24 are rotatably disposed within the equipment chamber and correspond one-to-one with a plurality of stirring shafts 14. The rotating sleeves 24 are mounted on the lower ends of the stirring shafts 14 extending into the equipment chamber. Each rotating sleeve 24 is fixedly provided with a pulley 242, each of which is connected by a belt 243. One of the rotating sleeves 24 is fixedly provided with a first gear 241, which meshes with the first rack 23. A guide key 142 is fixedly disposed along the axial direction of the lower end of the stirring shaft 14, which is slidably connected to a guide groove provided on the inner wall of the rotating sleeve 24.

[0046] The first motor 21 drives the wheel disc 22 to rotate, and the wheel disc 22 drives the guide shaft 221 to rotate. The guide shaft 221 cooperates with the long slot hole 231, so that the first rack 23 can slide horizontally on the slide rail. The first rack 23 drives one of the rotating sleeves 24 to rotate alternately forward and reverse through the first gear 241. The rotating sleeve 24 drives the stirring shaft 14 to rotate alternately forward and reverse through the cooperation of the guide groove and the guide key 142. When one of the rotating sleeves 24 rotates alternately forward and reverse, it can drive the other rotating sleeves 24 to rotate alternately forward and reverse through the cooperation of the pulley 242 and the belt 243, so that multiple stirring shafts 14 can rotate alternately forward and reverse at the same time, which can effectively stir the water.

[0047] Preferably, the first gear 241 is mounted on the outermost rotating sleeve 24 so that the pulley 242 can better drive the other pulleys 242 to rotate through the belt 243 .

[0048] In this embodiment, in conjunction with the appendix of the specification Figure 3 As can be seen, the lifting assembly 30 includes a lifting plate 31, which is arranged horizontally within the equipment cavity and is raised and lowered by the cylinder 32. The lifting plate 31 is connected to the rotating shaft of each stirring shaft 14. The piston rod of the cylinder 32 rises and falls, driving the lifting plate 31 to rise and fall, and the lifting plate 31 drives the multiple stirring shafts 14 to rise and fall synchronously.

[0049] Specifically, two cylinders 32 may be installed at both ends of the lifting plate 31 to ensure smoother lifting.

[0050] As an embodiment, Figure 1It can be seen that the filter assembly includes a filter plate 15 which is tilted and arranged in the filter cavity, a liquid inlet pipe 101 is provided above the filter plate 15, the lower end of the filter plate 15 is hinged to a support plate (not shown in the figure) in the filter cavity, and a collection box 151 is provided between the support plate and its corresponding inner wall of the filter cavity; the vibration assembly 40 is provided below the higher end of the filter plate 15, and is used to drive the filter plate 15 to vibrate.

[0051] like Figure 4 As shown, the vibration assembly 40 includes an eccentric wheel 41 arranged below the higher end of the filter plate 15 and rotated by the drive of the second motor 42; a sliding rod 43 is arranged on a horizontal plate (not shown in the figure) below the higher end of the filter plate 15 and can slide up and down. The outer circumferential surface of the eccentric wheel 41 contacts the first roller 44 at the lower end of the sliding rod 43, and the second roller 45 at the upper end of the sliding rod 43 contacts the lower surface of the filter plate 15.

[0052] The second motor 42 drives the eccentric wheel 41 to rotate. The eccentric wheel 41 contacts the first roller 44, so that the first roller 44 drives the sliding rod 43 to move up and down. The sliding rod 43 drives the higher end of the filter plate 15 to vibrate up and down through the second roller 45. The second roller 45 rolls by itself, so when it contacts the lower surface of the filter plate 15, it is rolling friction, which can reduce the damage caused by direct impact on the filter plate 15. When the filter plate 15 vibrates, impurities on the filter plate 15 can be shaken off and collected in the collection box 151 for later processing.

[0053] Specifically, a drainage hole is provided at the bottom of the collection box 151 to reduce residual water in the collection box 151 .

[0054] As an embodiment, Figure 5 As can be seen, the quick-release assembly 50 includes a connecting pipe 51 disposed between the free end of the liquid inlet pipe 101 and the end of the water inlet pipe 102. The connecting pipe 51 has tapered ends 52 with multiple through slots 53 formed therein. Two fixing sleeves 54 are sleeved on the connecting pipe 51 and threadedly connected thereto. The inner cavities of the fixing sleeves 54 mate with the tapered ends 52. The first and second quick-release assemblies 50 have the same structure.

[0055] The free end of the liquid inlet pipe 101 and the end of the water inlet pipe 102 are respectively sent into the connecting pipe 51 from the cones 52 at both ends, and then the fixing sleeve 54 on the connecting pipe 51 is rotated. While the two fixing sleeves 54 are away from each other, the fixing sleeve 54 squeezes the cone 52 of the connecting pipe 51 until the cone 52 clamps the liquid inlet pipe 101 and the water inlet pipe 102, and the liquid inlet pipe 101 and the water inlet pipe 102 can be installed. When disassembly is required, the fixing sleeve 54 is rotated to make the two fixing sleeves 54 close to each other until the cone 52 loosens the liquid inlet pipe 101 and the water inlet pipe 102, and the disassembly of the liquid inlet pipe 101 and the water inlet pipe 102 is completed, which can effectively and conveniently disassemble or install the liquid inlet pipe 101 and the water inlet pipe 102.
