Abstract
Description
Technical Field
[0001] This invention relates to the field of disinfection equipment, specifically to a pipeline-type hydrogen peroxide disinfection and sterilization device. Background Technology
[0002] In technologies related to hydrogen peroxide solution vaporization, flash evaporation is commonly used. This technology utilizes the principle that the boiling point increases under high pressure. A high-temperature, high-pressure hydrogen peroxide solution is introduced into a flash tank, lowering its boiling point. At this point, the temperature of the hydrogen peroxide solution is higher than its boiling point under the current pressure, causing the solution to rapidly boil and vaporize in the flash tank. In the prior art, utility model patent CN213374060U discloses a hydrogen peroxide flash vaporization device. This device improves vaporization by atomizing the hydrogen peroxide solution into tiny droplets upon entering the vaporization chamber. Some droplets falling to the bottom of the flash tank are also vaporized upon contact with the high-temperature inner wall of the flash tank. While this method can improve vaporization efficiency to some extent, the atomized droplets are easily discharged with the vaporized steam, resulting in incomplete vaporization of some hydrogen peroxide and affecting the uniformity of disinfection. Summary of the Invention
[0003] This invention provides a pipeline hydrogen peroxide disinfection and sterilization device to solve the problem of uneven vaporization of hydrogen peroxide affecting the disinfection effect in existing devices.
[0004] The pipeline-type hydrogen peroxide disinfection and sterilization device of the present invention adopts the following technical solution: A pipeline-type hydrogen peroxide disinfection and sterilization device includes a casing and an evaporation mechanism. The evaporation mechanism is disposed inside the casing and includes an outer shell, drippers, and a rotating frame. The rotating frame is rotatably mounted inside the outer shell around a vertical axis, and a first plate and a second plate are alternately arranged on the rotating frame around its circumference. Both the first plate and the second plate are heating plates, with the end closer to the rotation axis of the rotating frame being the inner end and the end farther from the rotation axis being the outer end. Elastic elements are provided between the first plate and the second plate and the rotating frame, causing the inner end of the first plate to be higher than the outer end, and the outer end of the second plate to be higher than the inner end. A first track and a second track are provided at the bottom of the outer shell, and the first plate and the second plate... The outer ends abut against the first and second tracks respectively under the action of the elastic element. The first and second tracks cause the first and second plates to oscillate periodically around the horizontal axis when rotating. In each cycle, the first and second plates first tend to be horizontal, then cross the horizontal and tilt in the opposite direction before returning to the initial tilt angle. There are multiple drippers, which are grouped in pairs. The two drippers in the same group move in opposite directions along the radial direction of the rotating frame. The two drippers in the same group correspond to the adjacent first and second plates respectively. By adjusting the rotation speed of the rotating frame and the dripping speed of the drippers, the liquid droplets from the drippers fall on the inner end of the first plate and the outer end of the second plate when the tilt is at its maximum when the rotating frame rotates.
[0005] The first and second plates have the same structure, both including a flat plate portion and two hook portions located at the inner and outer ends of the flat plate portion. The concave surfaces of the two hook portions face the flat plate portion to prevent droplets from flowing away from the flat plate portion.
[0006] The rotating frame is also equipped with multiple blocks, each located between two adjacent first and second plates, to block the dripper and prevent it from dropping liquid between the first and second plates.
[0007] The lower end of the dripper is a flexible drip tip. When the flexible drip tip comes into contact with the stop block, it contracts and is blocked by the stop block.
[0008] The first track includes multiple first bands that are continuously distributed around its circumference. Each first band includes a first gradual ascent segment, a first rapid ascent segment, a first rapid descent segment, and a first gradual descent segment connected in sequence. The inclination of the first rapid ascent segment and the first rapid descent segment is greater than that of the first gradual ascent segment and the first gradual descent segment.
[0009] The second track comprises multiple second bands that are sequentially distributed around its circumference. Each second band includes a second gradual descent segment, a second sudden descent segment, a second sudden ascent segment, and a second gradual ascent segment connected in sequence. The inclination of the second sudden descent segment and the second sudden ascent segment is greater than that of the second gradual descent segment and the second gradual ascent segment.
[0010] The evaporation mechanism also includes a guide plate, which is installed inside the outer casing. The guide plate has multiple guide grooves that are radially distributed around the rotation axis of the rotating frame. Each dripper is slidably installed in one guide groove. Two adjacent drippers form a group. Two drippers in the same group are connected by a telescopic connecting rod. The connecting rod is hinged to the two drippers, and the middle part of the connecting rod is rotatably installed on the guide plate around the vertical axis, so that the two drippers in the same group can move in opposite directions along the radial direction of the rotating frame.
[0011] One of the two drippers in each group is hinged to the same lifting plate via a hinge rod. The lifting plate is slidably mounted inside the housing and is raised and lowered by a drive component mounted on the housing, thereby causing one of the drippers in each group to slide along the guide groove.
[0012] The guide disc is rotatably installed inside the housing and its rotation axis is coaxial with the rotation axis of the rotating frame; the guide disc and the rotating frame both reciprocate around the vertical axis, and the rotation direction of the guide disc is opposite to the rotation direction of the rotating frame.
[0013] The bottom of the outer casing is sealed, and the guide plate, the bottom of the outer casing, and the side wall define the steam chamber; the side wall of the outer casing has an air inlet and an air outlet that communicate with the steam chamber.
[0014] The beneficial effects of this invention are as follows: In the pipeline-type hydrogen peroxide disinfection and sterilization device of this invention, the dripping head drips liquid onto the heated first and second plates, where it evaporates and vaporizes, preventing atomized droplets from being discharged with the steam. Furthermore, the rotation of the first and second plates with the rotating frame helps to separate the evaporated steam from the falling droplets, avoiding mixing of steam and droplets and thus preventing interference with steam discharge. Simultaneously, the tilting and oscillation of the first and second plates in opposite directions both disturb the steam, accelerating its discharge.
[0015] Furthermore, by setting up a first plate and a second plate that are tilted in opposite directions and configuring droplets that move in opposite directions, the droplets can fall at different positions on the first plate and the second plate, thereby enabling different positions on the first plate and the second plate to participate in the evaporation of the droplets. This avoids uneven temperature caused by localized evaporation on the first plate and the second plate, which would affect the temperature monitoring results of the first plate and the second plate.
[0016] Furthermore, by making the first plate and the second plate oscillate back and forth, the droplets can flow on the first plate and the second plate, extending the flow path of the droplets on the first plate and the second plate, allowing the droplets to fully contact the first plate and the second plate and thus evaporate quickly, and reducing the accumulation of droplets on the first plate and the second plate.
[0017] Furthermore, due to the rotation of the rotating frame, the droplets falling on the first plate are distributed in an oblique line, so that they do not overlap when flowing towards the lower outer end of the first plate. They can all contact the first plate and be heated and evaporated. Moreover, the reciprocating rotation of the rotating frame makes the droplets falling from the dripper on the first or second plate cross paths, further increasing the effective working area of the surface of the first and second plates and avoiding the continuous reception of droplets at the same position, which would affect the evaporation efficiency.
[0018] Furthermore, the first rapid rise and the first rapid fall of the first track cause the first plate to swing rapidly to the opposite tilt angle and then return to its original position. The second rapid fall and the second rapid rise of the second track cause the second plate to swing rapidly to the opposite tilt angle and then return to its original position. This causes the droplets on the first or second plate to quickly move back and forth on the surface of the first or second plate under the action of inertia, so that the liquid accumulated at the outer end of the first plate or the inner end of the second plate can be returned in time. The rapid swinging allows the liquid to be dispersed on the surface of the first or second plate, thus achieving rapid flash evaporation. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] An embodiment of the pipeline-type hydrogen peroxide disinfection and sterilization device of the present invention, such as... Figures 1 to 9 As shown, it includes a chassis 500 and an evaporation mechanism.
[0024] The evaporation mechanism is located inside the casing 500 and includes an outer shell 100, a dripper 300, and a rotating frame 400.
[0025] The outer casing 100 is fixed inside the housing 500, and the housing 500 contains an air inlet pipe 510 and an air outlet pipe 520 that communicate with the interior of the outer casing 100. A rotating frame 400 is rotatably mounted inside the outer casing 100 around a vertical axis, and a first plate 410 and a second plate 420 are alternately arranged around its circumference. Both the first plate 410 and the second plate 420 are heating plates, with the end closer to the rotation axis of the rotating frame 400 being the inner end and the end farther from the rotation axis being the outer end. Elastic members are provided between the first plate 410 and the second plate 420 and the rotating frame 400, causing the inner end of the first plate 410 to be higher than its outer end, and the outer end of the second plate 420 to be higher than its inner end.
[0026] The bottom of the outer casing 100 is provided with a first track 110 and a second track 120. The outer ends of the first plate 410 and the second plate 420 abut against the first track 110 and the second track 120 respectively under the action of the elastic element. The first track 110 and the second track 120 respectively cause the first plate 410 and the second plate 420 to swing periodically around the horizontal axis when rotating. In each cycle, the first plate 410 and the second plate 420 first tend to be horizontal and then tilt in the opposite direction after passing the horizontal before returning to the initial tilt angle.
[0027] There are multiple drippers 300, arranged in pairs. Two drippers 300 in the same pair move in opposite directions along the radial direction of the rotating frame 400. The two drippers 300 in the same pair correspond to the adjacent first plate 410 and second plate 420, respectively. By adjusting the rotation speed of the rotating frame 400 and the dripping speed of the drippers 300, when the rotating frame 400 rotates, the drippers 300 moving closer to the axis of the rotating frame 400 drip onto the second plate 420, and the drippers 300 moving away from the axis of the rotating frame 400 drip onto the first plate 410.
[0028] When the evaporation mechanism is working, hydrogen peroxide solution drips from the dripper 300. Simultaneously, the rotating frame 400 drives the first plate 410 and the second plate 420 to rotate, and the droplets fall onto the heated first plate 410 and second plate 420 to form steam. Gas is introduced into the outer casing 100 through the inlet pipe 510, carrying the steam from the evaporated hydrogen peroxide solution, which is then discharged through the outlet pipe 520 for disinfection and sterilization of the external environment. Specifically, by adjusting the rotation speed of the rotating frame 400 and the dripping speed of the dripper 300, when the rotating frame 400 rotates, droplets from the dripper 300 moving closer to the axis of the rotating frame 400 fall onto the second plate 420, while droplets from the dripper 300 moving away from the axis of the rotating frame 400 fall onto the first plate 410. As the dropper 300 moves toward the axis of the rotating frame 400, the droplets fall sequentially from the outer end to the inner end of the second plate 420, making full use of different positions of the second plate 420 to evaporate the droplets. At the same time, the second plate 420 rotates with the rotating frame 400, first rotating to a near-horizontal position to allow the droplets to flow slowly on the second plate 420, and then tilting in the opposite direction to return to the initial tilt angle, so that the droplets flow back and forth on the second plate 420, extending the flow path of the droplets on the second plate 420, allowing the droplets to fully contact the second plate 420 and evaporate quickly, and reducing the accumulation of droplets on the second plate 420. Similarly, when the dropper 300 moves away from the axis of the rotating frame 400, the droplets fall sequentially from the inner end of the first plate 410 to the outer end of the first plate 410. At the same time, the first plate 410 rotates with the rotating frame 400, first rotating to a near-horizontal position so that the droplets flow slowly on the first plate 410, and then tilting in the opposite direction and returning to the initial angle, so that the droplets flow back and forth on the first plate 410.
[0029] By setting the first plate 410 and the second plate 420 to tilt in opposite directions and configuring the droplet 300 to move in opposite directions, droplets can fall at different positions on the first plate 410 and the second plate 420. This allows different positions on the first plate 410 and the second plate 420 to participate in the evaporation of the droplets, avoiding uneven temperature caused by localized evaporation on the first plate 410 and the second plate 420, which would affect the temperature monitoring results of the first plate 410 and the second plate 420. Furthermore, by making the first plate 410 and the second plate 420 oscillate back and forth, droplets can flow on the first plate 410 and the second plate 420, extending the flow path of the droplets on the first plate 410 and the second plate 420, allowing the droplets to fully contact the first plate 410 and the second plate 420 for rapid evaporation, and reducing the accumulation of droplets on the first plate 410 and the second plate 420. The first plate 410 and the second plate 420, which rotate with the rotating frame 400, can cause the evaporated steam and falling droplets to be staggered, avoiding mixing of steam and droplets and affecting the discharge of steam. At the same time, the first plate 410 and the second plate 420 tilt and swing in opposite directions, which can both disturb the steam and accelerate its discharge. Due to the rotation of the rotating frame 400, the droplets falling on the first plate 410 are distributed obliquely, so that they do not overlap when flowing towards the lower outer end of the first plate 410. They can all contact the first plate 410 and be heated and evaporated. Furthermore, the reciprocating rotation of the rotating frame 400 causes the droplets dripping from the dripper 300 to have intersecting paths on the first plate 410 or the second plate 420, further increasing the effective working area of the surfaces of the first plate 410 and the second plate 420 and avoiding the continuous reception of droplets at the same position, which would affect the evaporation efficiency.
[0030] In this embodiment, the first plate 410 and the second plate 420 have the same structure, both including a flat plate portion and two hook portions located at the inner and outer ends of the flat plate portion. The concave surfaces of the two hook portions face the flat plate portion to prevent droplets from flowing away from the flat plate portion. The hook portions prevent droplets from flowing away when the first plate 410 or the second plate 420 swings to a reverse tilt, and guide droplets back to the flat plate portion when the first plate 410 or the second plate 420 returns to its initial tilt angle. In some other embodiments, the first plate 410 and the second plate 420 are also provided with baffles (not shown in the figure) on both sides of the first plate 410 and the second plate 420 in the circumferential direction of the rotating frame 400 to prevent droplets on the first plate 410 and the second plate 420 from flowing away when they rotate with the rotating frame 400.
[0031] In this embodiment, the first plate 410 and the second plate 420 are hollow inside and connected to an external steam mechanism via flexible hoses for introducing high-temperature steam to heat the first plate 410 and the second plate 420. In some other embodiments, heating wires may also be provided inside the first plate 410 and the second plate 420, and the first plate 410 and the second plate 420 are heated by energizing the heating wires.
[0032] In this embodiment, the rotating frame 400 is also provided with a plurality of blocks 430, each block 430 being located between two adjacent first plates 410 and second plates 420, used to block the dripping head 300 and prevent the dripping head 300 from dropping liquid between the first plates 410 and second plates 420. The block 430 is suspended above the space between the first plates 410 and second plates 420 by a support rod, and its projection on the horizontal plane is adapted to the space between the first plates 410 and second plates 420, so that it neither affects the dropping of liquid onto the first plates 410 and second plates 420 nor prevents the dropping of liquid onto the space between the first plates 410 and second plates 420.
[0033] In this embodiment, the lower end of the dropper 300 is an elastic tip. When the elastic tip comes into contact with the stop block 430, it contracts and is blocked by the stop block 430. Specifically, the elastic tip contracts when it comes into contact with the stop block 430, reducing wear on the dropper 300.
[0034] In this embodiment, the first track 110 includes a plurality of first wavebands that are continuously distributed around its circumference. Each first waveband includes a first gradual rise segment, a first sudden rise segment, a first sudden fall segment, and a first gradual fall segment connected in sequence. The inclination of the first sudden rise segment and the first sudden fall segment is greater than that of the first gradual rise segment and the first gradual fall segment. A first push rod 411 is provided on the lower side of the first plate 410. Under the action of the elastic element between the first plate 410 and the rotating frame 400, the first push rod 411 is always in contact with the first track 110. When moving along the first waveband, the first plate 410 first slowly tends to be horizontal along the first gradual rise segment, then quickly crosses the horizontal position along the first sudden rise segment and tilts in the opposite direction, then quickly falls back to the initial tilt direction along the first sudden fall segment, and then slowly returns to the initial tilt angle along the first gradual fall segment. The first rapid rise and the first rapid fall phase cause the first plate 410 to swing rapidly to the reverse tilt angle and then return to its original position. This causes the droplets on the first plate 410 to quickly travel back and forth on the surface of the first plate 410 under the action of inertia, so that the liquid accumulated at the outer end of the first plate 410 can flow back in time. The rapid swinging also disperses the liquid on the surface of the first plate 410, thus achieving rapid flash evaporation.
[0035] In this embodiment, the second track 120 includes a plurality of second wavebands that are continuously distributed around its circumference. The second wavebands include a second gradual descent section, a second sudden descent section, a second sudden ascent section, and a second gradual ascent section connected in sequence. The inclination of the second sudden descent section and the second sudden ascent section is greater than that of the second gradual descent section and the second gradual ascent section. A second push rod 421 is provided on the lower side of the second plate 420. Under the action of the elastic element between the second plate 420 and the rotating frame 400, the second push rod 421 is always in contact with the second track 120. When moving along the second waveband, the second plate 420 first slowly tends to be horizontal along the second gradual descent section, then quickly crosses the horizontal position along the second sudden descent section and tilts in the opposite direction, then quickly falls back to the initial tilt direction along the second sudden ascent section, and then slowly returns to the initial tilt angle along the second gradual ascent section. The second descent and the second ascent phases cause the second plate 420 to swing rapidly to the opposite tilt angle and then return to its original position. This causes the droplets on the second plate 420 to rapidly travel back and forth on the surface of the second plate 420 under the action of inertia, so that the liquid accumulated at the inner end of the second plate 420 can flow back in time. The rapid swinging also disperses the liquid on the surface of the second plate 420, achieving rapid flash evaporation.
[0036] In this embodiment, the evaporation mechanism further includes a guide disk 200, which is installed inside the housing 100. The guide disk 200 has multiple guide grooves 210 radially distributed around the rotation axis of the rotating frame 400. That is, the center of the guide disk 200 is coaxial with the rotation axis of the rotating frame 400, and each guide groove 210 extends radially along the guide disk 200. Each dropper 300 is slidably mounted in a guide groove 210 and is constrained by the guide groove 210 to remain in contact with it. Two adjacent droppers 300 form a group, and two droppers 300 in the same group are connected by a telescopic connecting rod 310. The connecting rod 310 is hinged to the two droppers 300, and the middle part of the connecting rod 310 is rotatably mounted on the guide disk 200 around a vertical axis, so that the two droppers 300 in the same group move in opposite directions radially along the rotating frame 400. The two droppers 300 moving in opposite directions can simultaneously drop liquid onto adjacent first plates 410 and second plates 420.
[0037] In this embodiment, one of the two drippers 300 in each group is hinged to the same lifting plate 320 via a hinge rod 340. The lifting plate 320 is slidably mounted inside the housing 100 and is raised and lowered by a drive component 330 mounted on the housing 100, thereby causing one dripper 300 in each group to slide along the guide groove 210. The drive component 330 is a hydraulic telescopic cylinder and is fixed to the top cover 150 of the housing 100. A main pipe 130 and multiple branch pipes connected to the main pipe 130 are mounted on the top cover 150 of the housing 100. Each branch pipe is connected to one dripper 300. The main pipe 130 is used to input hydrogen peroxide solution into the dripper 300. The dripper 300 is a dripping head in the prior art, capable of intermittently dripping droplets; its specific structure will not be described in detail. In some other embodiments, the drive component 330 may also be a combination of a motor and a lead screw nut.
[0038] In this embodiment, the guide disk 200 is rotatably mounted inside the housing 100, and its rotation axis is coaxial with the rotation axis of the rotating frame 400. The guide disk 200 and the rotating frame 400 both reciprocate around a vertical axis, and the rotation direction of the guide disk 200 is opposite to that of the rotating frame 400. The rotation of the guide disk 200 in the opposite direction to the rotating frame 400 ensures relative movement between the dropper head 300 and the first plate 410 or the second plate 420, while also reducing the need for a high rotation speed of the rotating frame 400, thus preventing the droplets on the first plate 410 and the second plate 420 from being thrown out. The rotating frame 400 has a gear shaft 440 at its center, on which a central gear 441 is fixed. The guide disk 200 is hollow at its center, and a gear ring 260 is provided on its inner ring. The gear ring 260 and the central gear 441 are driven by a planetary gear 270. The planetary gear 270 meshes with both the gear ring 260 and the central gear 441, and its center is rotatably mounted on a planetary shaft, which is fixed to the top cover 150 of the outer casing 100. The rotation of the rotating frame 400 drives the central gear 441 to rotate, which in turn drives the guide disk 200 to rotate via the planetary gear 270 and the gear ring 260. By configuring the transmission ratio between the planetary gear 270 and the central gear 441 or the gear ring 260, the guide disk 200 can rotate at a suitable speed in the opposite direction to the rotating frame 400. In some other embodiments, the guide disk 200 and the rotating frame 400 can be driven by separate motors for reciprocating rotation.
[0039] In this embodiment, the bottom of the outer casing 100 is sealed by the base plate 140, and the guide plate 200, the base plate 140, and the side wall of the outer casing 100 define a steam chamber. An air inlet 101 and an air outlet 102 communicating with the steam chamber are provided on the side wall of the outer casing 100. The air inlet 101 is connected to the air inlet pipe 510, and the air outlet 102 is connected to the air outlet pipe 520. A fan 530 is also provided inside the casing 500 for supplying air to the air inlet pipe 510.
[0040] In use, the pipeline-type hydrogen peroxide disinfection and sterilization device of the present invention heats the first plate 410 and the second plate 420, introduces hydrogen peroxide solution into the dripper 300, starts the fan 530 to send air into the air inlet pipe 510, and causes the rotating frame 400 and the guide plate 200 to rotate back and forth in opposite directions.
[0041] Droplets from the dripper 300, moving along the guide groove 210 away from the center of the guide disk 200, fall sequentially onto the first plate 410 from the inside out. By adjusting the rotation speed of the rotating frame 400, the initial droplets fall at the inner end of the first plate 410 when its initial tilt is at its maximum. Because the rotating frame 400 and the guide disk 200 rotate relative to each other, the droplets falling on the first plate 410 are distributed obliquely, thus preventing them from overlapping as they flow towards the lower outer end of the first plate 410. All droplets then contact the first plate 410 and are heated and evaporated. Droplets from the dripper 300, moving along the guide groove 210 towards the center of the guide disk 200, fall sequentially onto the second plate 420 from the outside in, with the initial droplets falling at the outer end of the second plate 420 when its initial tilt is at its maximum. Because the rotating frame 400 and the guide plate 200 rotate relative to each other, the droplets falling on the second plate 420 are distributed in an oblique line. As they flow towards the lower inner end of the second plate 420, they do not come into contact with each other and can all come into contact with the second plate 420 and be heated and evaporated.
[0042] Taking the first plate 410 as an example, as the droplet falls onto the first plate 410, the first plate 410 swings under the guidance of the first track 110. The first plate 410 first slowly approaches horizontal along the first gradual rise section, then quickly crosses the horizontal position along the first sudden rise section and tilts in the opposite direction. After that, it quickly falls back to the initial tilt direction along the first sudden fall section, and then slowly returns to the initial tilt angle along the first gradual fall section. The first sudden rise section and the first sudden fall section cause the first plate 410 to swing quickly to the opposite tilt angle and then return to its original position. This allows the droplet on the first plate 410 to quickly travel back and forth on the surface of the first plate 410 under the action of inertia, so that the liquid accumulated at the outer end of the first plate 410 can flow back in time. The rapid swinging also disperses the liquid on the surface of the first plate 410, achieving rapid flash evaporation.
[0043] The first plate 410 and the second plate 420 oscillate back and forth as the rotating frame 400 rotates, disturbing the steam formed after the droplets evaporate, so that it is discharged with the air entering through the air inlet 101 and flows out through the air outlet 102 and the air outlet pipe 520, disinfecting and sterilizing specific locations outside the chassis 500.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
