[0034] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] A sanitary filtration adsorption unit for ships according to a preferred embodiment of the present invention will be described in detail below.

[0036] like Figure 1-Figure 10 As shown, a sanitary filtering and adsorption unit for ships comprises a hollow filter seat 1, a front connecting pipe 11 and a rear connecting pipe 12 are fixedly connected to the front and rear ends of the filter seat 1 respectively, a collecting box 13 is slidably inserted at the bottom of the filter seat 1, a leakage groove 14 connected to the collecting box 13 is opened on the lower wall of the inner cavity of the filter seat 1, an annular tooth segment 15 is arranged on the front side of the inner wall of the filter seat 1, a filter ring 2 and an activated carbon ring 3 are fixedly connected to the rear side of the inner wall of the filter seat 1 in sequence, and an annular tooth segment 2 21 is fixedly connected to the front wall of the filter ring 2;

[0037] The front end of the filter ring 2 is rotatably connected to a rotating cover 4, and a strip cover 41 is fixedly connected to the lower wall of the rotating cover 4. Two hollow cleaning tooth rollers 42 extending into the rotating cover 4 are rotatably connected in the strip cover 41, and the tops of the two cleaning tooth rollers 42 are meshed and connected. The side walls of the cleaning tooth rollers 42 are provided with multiple rows of spray holes 43, and a one-way valve is provided in the spray hole 43. A sponge sleeve 44 is fixedly sleeved on the outside of the cleaning tooth roller 42, and the sponge sleeves 44 and the sponge sleeves 44 and the inner wall of the strip cover 41 are movably abutted. A storage tank is provided on the front side of the inner cavity of the strip cover 41, a liquid pump 53 is provided in the middle of the filter ring 2, and a cleaning liquid cylinder 55 is fixedly connected to the rear side of the filter seat 1;

[0038] An inner worm gear 63 meshing with an annular tooth segment 15 is provided on the right side of the rotating cover 4, and an energy storage gear 7 meshing with an annular tooth segment 21 is rotatably connected to the upper wall of the inner cavity of the rotating cover 4, and a ratchet gear 71 is rotatably connected to the lower end of the energy storage gear 7, and a volute spring 72 is provided between the ratchet gear 71 and the energy storage gear 7, and a slide rod 74 is movably inserted in the middle of the ratchet gear 71, and a push plate 75 is fixedly connected to the lower end of the slide rod 74, and the push plate 75 is movably clamped on the top of the storage tank, and the push plate 75 is adapted to the storage tank. A curved groove 76 is provided on the periphery of the slide rod 74, and a pin protrusion 73 movably clamped with the curved groove 76 is fixedly connected to the inner wall of the ratchet gear 71, and a limiting component is provided on the rear side of the inner cavity of the rotating cover 4, and the limiting component is used to store energy and limit the ratchet gear 71.

[0039] The storage tank extends to the lower wall of the strip cover 41 , the lower wall of the strip cover 41 is rotatably connected to the inner wall of the filter seat 1 , and the lower port of the storage tank is connected to the drain groove 14 .

[0040] Furthermore, the curved groove 76 is opened around the outer wall of the sliding rod 74 in a curved ring shape and is connected end to end.

[0041] When the device is in use, it is installed in the ventilation duct, with air intake through the front connecting pipe 11 and exhaust through the rear connecting pipe 12. The filter ring 2 can filter dust in the air. After filtering, germs, odors, etc. in the air are adsorbed by the activated carbon ring 3. When the filter ring 2 needs to be cleaned, the cleaning liquid in the cleaning liquid cylinder 55 is extracted and pressed into the two cleaning tooth rollers 42 by controlling the operation of the liquid pump 53. The two cleaning tooth rollers 42 quickly discharge the cleaning liquid through the multiple columns of spray holes 43 to wet the sponge cover 44. The use of the one-way valve in the spray hole 43 can avoid subsequent stopping of cleaning. The cleaning liquid in the cleaning tooth roller 42 automatically flows out, controlling the two cleaning tooth rollers 42 to rotate toward one side of the filter ring 2, and the two wet sponge sleeves 44 automatically sweep the dust on the front wall of the filter ring 2 and absorb it into the storage tank, and when the sponge sleeve 44 continues to rotate, the inner wall of the storage tank automatically scrapes the dust on the surface of the sponge sleeve 44 and retains it in the storage tank. During this period, the inner worm gear 63 meshes with the annular tooth segment 15 to drive the rotating cover 4 and the strip cover 41 to rotate at a low speed to ensure that the two cleaning tooth rollers 42 have enough time to deeply clean the filter ring 2. When the two cleaning tooth rollers 42 have made one revolution, the filter ring 2 can be cleaned thoroughly. The filter ring 2 is fully cleaned. Since the cleaned dust is gathered in a relatively closed storage tank, dust leakage caused by airflow is avoided, and the online cleaning of the filter ring 2 is realized. When the rotating cover 4 rotates, the rotating cover 4 drives the energy storage gear 7 to mesh and rotate on the annular tooth segment 21, and the limit component automatically limits the rotation of the ratchet gear 71, and the volute spring 72 automatically compresses and accumulates elastic potential energy. When the rotating cover 4 rotates one circle and drives the strip cover 41 to make the lower port of the storage tank dock with the leakage tank 14 again, the limit component releases the restriction on the ratchet gear 71, and the ratchet gear 71 is rotated on the volute spring 72. The cam 73 is used to squeeze the inner wall of the curved groove 76 to force the curved groove 76 to drive the slide bar 74 to move back and forth. The slide bar 74 drives the push plate 75 to push the dust in the storage tank out and drop it into the collection box 13 through the leakage groove 14, so as to clean the storage tank and avoid excessive accumulation of dust in the storage tank, which is not conducive to the subsequent cleaning tooth roller 42 driving the sponge sleeve 44 to continue to feed the dust. In addition, since the cleaning part of this design is relatively located on both sides of the filter ring 2 and is located in the filter seat 1, the external space occupied is relatively small, which is convenient for overall field layout and use.

[0042] In this embodiment, there is a gap between the strip cover 41 and the front wall of the filter ring 2 , and the sponge cover 44 is movably in contact with the front wall of the filter ring 2 .

[0043] When cleaning the filter ring 2, the rotating cover 4 drives the strip cover 41 to rotate along the axis of the filter ring 2. The gap between the strip cover 41 and the front wall of the filter ring 2 prevents the strip cover 41 from scraping dust before the sponge cover 44, ensuring that the wet sponge cover 44 that is movably in contact with the front wall of the filter ring 2 can reliably clean the dust.

[0044] In this embodiment, a transmission bevel gear 45 is rotatably connected to the lower wall of the inner cavity of the rotating cover 4, a transmission belt 46 is movably sleeved between the transmission bevel gear 45 and the left cleaning tooth roller 42, a limiting roller 47 movably abutting against the transmission belt 46 is rotatably connected to the lower wall of the inner cavity of the rotating cover 4, a driving bevel gear 48 meshing with the transmission bevel gear 45 is rotatably connected to the front wall of the inner cavity of the rotating cover 4, and a driving motor for driving the driving bevel gear 48 is provided at the front end of the rotating cover 4.

[0045] The driving bevel gear 48 is driven by the driving motor to rotate the transmission bevel gear 45, and the transmission bevel gear 45 then drives the cleaning tooth roller 42 on the left to rotate through the transmission belt 1 46, so that the cleaning tooth roller 42 on the right automatically meshes with the cleaning tooth roller 42 on the left to rotate, and the cleaning tooth rollers 42 on both sides rotate in opposite directions. When the cleaning tooth rollers 42 on both sides rotate toward one side of the filter ring 2 by controlling the steering direction of the driving bevel gear 48, it is convenient to perform a centered closed cleaning of the dust on the front wall of the filter ring 2;

[0046] The limiting roller 47 is used to deform the transmission belt 46 so as to facilitate the slide bar 74 to avoid the movement interference between the transmission belt 46 and the slide bar 74.

[0047] In this embodiment, the front connecting pipe 11 is trumpet-shaped, and a blocking column portion is provided in the middle of the front connecting pipe 11 . The front end of the blocking column portion is conical, and the rear end is movably sleeved on the rotating cover 4 .

[0048] When air enters through the front connecting pipe 11, the trumpet-shaped design is convenient for expanding the flow range of the airflow, so as to make full use of the filter ring 2 to filter the airflow, and when the airflow hits the conical front end of the baffle part, it is dispersed quickly and the energy is weakened less, thus avoiding direct impact on the drive motor at the front end of the rotating cover 4, causing greater energy weakening and reducing the flow rate, while avoiding dust intrusion into the drive motor to affect its heat dissipation.

[0049] In this embodiment, a transition bin 5 is fixedly connected to the inner wall of the filter ring 2, a sealing turntable 51 is rotatably connected to the front end of the transition bin 5, two sealing joints 52 are fixedly connected to the front end of the sealing turntable 51, and the two sealing joints 52 are respectively rotatably connected to the top ends of the corresponding cleaning tooth rollers 42. A liquid pump 53 is fixedly connected to the rear end of the transition bin 5, and the output end of the liquid pump 53 is connected to the transition bin 5. A conduit 54 is fixedly connected to the input end of the liquid pump 53, and the conduit 54 is connected to a cleaning liquid cylinder 55. Alcohol disinfectant is provided in the cleaning liquid cylinder 55.

[0050] When cleaning the filter ring 2, the liquid pump 53 draws the alcohol disinfectant in the cleaning liquid cylinder 55 into the transition bin 5 through the conduit 54, and presses the alcohol disinfectant in the transition bin 5 into the cleaning tooth roller 42 through the sealing joint 52. The design of the sealing joint 52 being rotatably connected to the top of the cleaning tooth roller 42 and the sealing turntable 51 being rotatably connected to the transition bin 5 facilitates the stable replenishment of the alcohol disinfectant when the cleaning tooth roller 42 rotates and revolves. In addition, the design of using alcohol disinfectant as the cleaning liquid is not only convenient for disinfecting bacteria on the filter ring 2, but also convenient for rapid volatilization to avoid affecting the humidity of the ventilation airflow.

[0051] In this embodiment, a hollow connecting strip 6 is fixedly connected to the right wall of the rotating cover 4, a sealing ring 61 is fixedly connected to the right end of the connecting strip 6, the sealing ring 61 is rotatably connected to the inner wall of the filter seat 1, an inner worm gear 63 is rotatably connected to the right wall of the sealing ring 61, a transmission belt 2 64 is movably sleeved between the inner worm gear 63 and the transmission bevel gear 45, the transmission belt 2 64 is in the inner cavity of the connecting strip 6, an annular tooth segment 15 is in the inner cavity of the sealing ring 61, and an edge 62 rotatably connected to the inner wall of the filter seat 1 is provided on the lower wall of the sealing ring 61, and the edge 62 movably seals the leakage groove 14.

[0052] When cleaning the filter ring 2, the driving motor drives the driving bevel gear 48 to rotate the transmission bevel gear 45, and the transmission bevel gear 45 synchronously drives the inner worm gear 63 to rotate through the transmission belt 2 64. The inner worm gear 63 engages with the annular tooth segment 15 to drive the rotating cover 4 and the strip cover 41 to rotate counterclockwise at a low speed. The two cleaning tooth rollers 42 can thus revolve at a low speed to perform a deep and comprehensive cleaning of the filter ring 2. During cleaning, the annular tooth segment 15 is relatively sealed and protected by the sealing ring 61, so that the annular tooth segment 15 is prevented from being contaminated by dust and affecting the stability of the engagement with the inner worm gear 63. At the same time, the edge 62 movably seals the leakage groove 14, so that the dust in the collection box 13 is prevented from being sucked out by the airflow in the filter seat 1.

[0053] In this embodiment, a protection tube 77 is fixedly connected to the upper wall of the rotating cover 4 , the protection tube 77 is rotatably abutted against the inner wall of the filter seat 1 , and the top end of the slide rod 74 is slidably engaged with the inner wall of the protection tube 77 .

[0054] The use of the protective tube 77 prevents the dust on the filter ring 2 from invading the curved groove 76. At the same time, since the top of the slide rod 74 is slidably engaged with the inner wall of the protective tube 77, the linear movement stability of the push plate 75 driven by the slide rod 74 in the storage tank is enhanced, and the slide rod 74 can more reliably drive the push plate 75 to push out the dust in the storage tank, thereby cleaning the storage tank.

[0055] In this embodiment, the transmission ratio between the energy storage gear 7 and the annular tooth segment 21 is greater than 1 and is an integer.

[0056] When the rotating cover 4 rotates one circle, the energy storage gear 7 meshes with the annular tooth segment 21 for at least two circles, so the ratchet gear 71 is energized by the spiral spring 72, and the ratchet gear 71 can also rotate at least two circles, thereby ensuring that the ratchet gear 71 uses the pin protrusion 73 to squeeze the inner wall of the curved groove 76, forcing the curved groove 76 to drive the slide bar 74 to move back and forth at least two complete rounds, thereby avoiding the slide bar 74 failing to drive the push plate 75 to be at the top of the storage tank during subsequent cleaning and resetting, affecting the cleaning effect.

[0057] In this embodiment, the limiting assembly includes a support rod 49 fixedly connected to the inner wall of the rotating cover 4, and a pillar 8 is slidably engaged with the middle part of the support rod 49. The pillar 8 is located on the rear side of the ratchet gear 71. The front end of the pillar 8 is rotatably connected to a torsion wedge 81. A torsion spring is provided between the torsion wedge 81 and the pillar 8. The torsion wedge 81 can be movably engaged with the ratchet gear 71. A guide rod 82 is fixedly connected to the upper wall of the pillar 8. A guide groove 22 movably engaged with the guide rod 82 is provided on the inner wall of the filter ring 2. The guide groove 22 is annular as a whole and the top is bent backward.

[0058] In the initial state, the strip cover 41 is vertically downward and the storage tank is docked with the leakage tank 14. The pillar 8 drives the guide rod 82 to flexibly engage with the top curved part of the guide groove 22. When the inner worm gear 63 engages with the annular tooth segment 15 to drive the rotating cover 4 and the strip cover 41 to rotate counterclockwise at a low speed, the pillar 8 also follows the rotating cover 4 to rotate counterclockwise, and the pillar 8 drives the guide rod 82 to move away from the top curved part of the guide groove 22. The pillar 8 is automatically moved forward under the drive of the guide rod 82 to drive the torsion wedge 81 to flexibly engage with the ratchet gear 71. During this period, the energy storage gear 7 is driven by the rotating cover 4 to engage with the annular tooth segment 21 to rotate. Due to the engagement restriction of the torsion wedge 81 on the ratchet gear 71, the ratchet gear 71 cannot rotate, and the volute spring 72 is thus 7 continuously stores energy under the rotation. When the rotating cover 4 rotates one circle, that is, the cleaning tooth roller 42 revolves one circle to fully clean the front wall of the filter ring 2, the rotating cover 4 drives the strip cover 41 to return to the initial position again, the storage tank is docked with the leakage groove 14 again, and the corresponding guide rod 82 is movably engaged with the curved part at the top of the guide groove 22 again. The pillar 8 drives the torsion wedge block 81 to move backward to cancel the engagement restriction on the ratchet gear 71, and the volute spring 72 automatically releases energy. The ratchet gear 71 automatically rotates under the elastic force of the volute spring 72, and the pin convex 73 is used to squeeze the inner wall of the curved groove 76 to force the curved groove 76 to drive the slide bar 74 to move back and forth. The slide bar 74 thereby drives the push plate 75 to push the dust in the storage tank into the collection box 13, thereby realizing the cleaning of the storage tank.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
