Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a rainwater purification apparatus 100 with a separated deposition function, which includes a housing 1 and a driving mechanism. The driving mechanism is arranged on the machine shell 1. The machine shell 1 is internally provided with a water receiving tank 3, a water collecting chamber 4, an atomizing and disinfecting chamber 5 and a water purifying chamber 6 from top to bottom in sequence.

The water receiving tank 3 is used for receiving rainwater. The water receiving tank 3 is provided with a water outlet hole. A first filter screen 31 is arranged at the water outlet. The first filter 31 is used for filtering water flowing through the water outlet holes. Preferably, rainwater in the water receiving tank 3 flows out from the water outlet hole under the action of self gravity.

The bottom of the water collection chamber 4 is provided with a sprinkler head 41. The water collecting chamber 4 is used for receiving water flowing out of a water outlet hole of the water receiving tank 3 and spraying the water into the atomized sterilizing chamber 5 through the spraying head 41.

The aerosol sterilisation chamber 5 comprises a drum 51 and a filter plate 52. The drum 51 is rotatable about its own axis. The axis of the drum 51 is vertically disposed. The atomized sterilizing chamber 5 receives the water sprayed from the spray head 41 through the upper end opening of the drum 51. The drum 51 is provided with a sterilizing device 511 on a side wall thereof. The sterilizing device 511 is used for sterilizing the water in the drum 51. The sterilizing device 511 includes two or more ultraviolet sterilizing devices 5112 and two or more high-temperature sterilizing devices 5111. The ultraviolet ray sterilizing devices 5112 and the high temperature sterilizing devices 5111 are equal in number and are sequentially staggered in the circumferential direction of the drum 51. The ultraviolet ray sterilizing unit 5112 may emit ultraviolet rays to sterilize rainwater in the drum 51. The high temperature sterilizing device 5111 may heat rainwater in the drum 51 to sterilize the rainwater by high temperature. Wherein, because the rain water sprayed from the spray head 41 has the atomization effect, the atomized rain water can be sufficiently dispersed in a relatively large space in the drum 51 with respect to the water flow, thereby having a large disinfection area, which is advantageous for the ultraviolet ray disinfection device 5112 and the high temperature disinfection device 5111 to disinfect.

The driving mechanism is used for driving the rotary drum 51 to rotate back and forth in a range of 0-180 degrees around the axis of the rotary drum. On one hand, the rotating drum 51 can drive the ultraviolet disinfection device 5112 and the high-temperature disinfection device 5111 thereon to rotate together, so as to fully disinfect the rainwater at different positions in the rotating drum 51 in the circumferential direction, so that the rainwater at each position in the rotating drum 51 is disinfected more uniformly, and the disinfection effect is better. On the other hand, the connecting of the conductive paths of the ultraviolet ray sterilizing device 5112 and the high temperature sterilizing device 5111 can be prevented from being affected by the excessively large rotational width of the rotary drum 51.

The aforementioned filter plate 52 is disposed below the drum 51. The filter plate 52 serves to filter the water exiting the drum 51. A plurality of vibration rods 521 are provided on one surface of the filter plate 52 adjacent to the drum 51. The vibrating rod 521 has a ball head 522 at the top and extends into the rotating drum 51. The vibration rod 521 is used for generating vibration under the impact of rainwater sprayed from the sprinkler 41 to further atomize the rainwater, so as to increase the disinfection area of the rainwater, thereby further improving the disinfection effect of the disinfection device 511 on the rainwater in the rotary drum 51.

The filter plate 52 has a first region with a circular shape. The centre line of the first area coincides with the centre line of the spray head 41. The plurality of vibration bars 521 are uniformly distributed in the first region. The vibrating rods 521 have different heights and gradually decrease outward from the center line of the circular area. Among them, the height of the vibratory rod 521 closest to the center line of the circular region is the highest, and for convenience of description, the vibratory rod 521 is taken as the first vibratory rod. The first vibrating rod vibrates the rainwater to the side when vibrating, and the rainwater can drop downwards under the action of gravity. And because the height that is located the second vibrating arm of first vibrating arm side is lower relatively first vibrating arm, the rainwater that first vibrating arm shakes and falls can just fall on the second vibrating arm, with further carrying out vibration atomizing, so analogize, the rainwater that first vibrating arm shakes and falls can transmit the vibrating arm in the outside always and carry out vibration atomizing, can further improve the atomization effect of rainwater in rotary drum 51 like this, the disinfection area of rainwater has further been improved, thereby the disinfection effect of rainwater in rotary drum 51 has further been improved to degassing unit 511.

The clean water chamber 6 is for receiving water flowing out of the filter plate 52, and a drain port is provided at the bottom of the clean water chamber 6.

In the technical scheme provided by the invention, the atomizing disinfection chamber 5 can be used for carrying out high-temperature and ultraviolet double disinfection on the atomized rainwater, and the first filter screen 31 is matched for filtering the rainwater, so that the rainwater can be fully purified by the technical scheme provided by the invention, and the purification effect is good.

In a specific example of application, as shown in fig. 2, the sterilizing devices 511 are uniformly distributed in a circle around the axis of the rotating drum 51. The rotation angle of the drum 51 is identical to the central angle a2 corresponding to two adjacent ultraviolet ray sterilizing devices 5112. For example, the number of both the ultraviolet ray sterilizing device 5112 and the high temperature sterilizing device 5111 is two, the total number of the sterilizing devices 511 is four. The four sterilizing devices 511 are evenly distributed in a circle around the axis of the rotary drum 51. Wherein, the central angle corresponding to two adjacent sterilizing devices 511 is 90 degrees. The central angles of the two adjacent ultraviolet ray disinfection devices 5112 and the two adjacent high temperature disinfection devices 5111 are all 180 degrees. The rotation angle of the drum 51 is 180 degrees. That is, the driving mechanism drives the drum 51 to rotate from the 0 degree position to the 180 degree position, and then drives the drum 51 to rotate from the 180 degree position to the 0 degree position, so that the drum 51 is rotated in a reciprocating manner.

Through the arrangement, the technical effect that the rotating drum 51 can disinfect rainwater in the rotating drum 51 in 360-degree dead angles in the minimum rotating angle range can be achieved, and interference on connecting wires of the disinfecting devices 511 is reduced.

Further, as shown in fig. 1, the aforementioned rainwater purification apparatus 100 having the separated deposition function may further include a drawer 7. The water receiving tank 3 has a first side wall 301. The bottom of the first sidewall 301 has a drawer hole 3011. The drawer 7 has an outer shape adapted to the bottom of the water receiving tank 3, for example, both are square. The drawer 7 is drawably disposed in the drawer hole 3011. The drawer 7 is hermetically engaged with the drawer hole 3011 when inserted into the drawer hole 3011, so as to prevent water in the water receiving tank 3 from flowing out of the drawer hole 3011. The lower end of the water outlet hole corresponds to the upper end of the drawer 7, so that water higher than the drawer 7 overflows from the water outlet hole.

Through foretell setting, can make the debris separation of rainwater come the deposit in drawer 7, and the rainwater then spills over from the apopore, so can reach the effect of preliminary purification to the rainwater. When the sundries in the drawer 7 are more, the drawer 7 can be pulled out to clean the sundries in the drawer.

Further, as shown in fig. 1, a stopper plate 71 may be disposed on an outer wall of the drawer 7. When the drawer 7 is inserted into the drawer hole 3011, the position-limiting plate 71 abuts against the outer wall of the housing 1, and the two are fixed by the screw 8. Thus, when the drawer 7 is not required to be pulled out, the drawer 7 can be tightly fixed in the drawer hole 3011 to prevent the drawer 7 from being pulled out of the drawer hole 3011.

As shown in fig. 1, the water receiving tank 3 further has a second side wall 302 opposite to the first side wall 301. The second sidewall 302 has an angled section 3021. The upper end of the inclined section 3021 is inclined to a side near the first sidewall 301 with respect to the lower end. The water outlet hole is disposed on the second sidewall 302.

Through the arrangement, sundries such as leaves in the water receiving tank 3 can be prevented from being attached to the first filter screen 31, so that the filtering effect of the first filter screen 31 is not affected.

Further, as shown in fig. 1, the opening at the upper end of the water receiving tank 3 may be a flared opening to increase the opening area of the water receiving tank 3 and improve the water receiving efficiency of the water receiving tank 3.

Further, as shown in fig. 1, a second filter screen 9 may be disposed at an upper opening of the water receiving tank 3 to filter rainwater flowing into the water receiving tank 3 roughly, so as to further improve a filtering effect of the rainwater.

Further, as shown in fig. 1, the bottom of the water collecting chamber 4 has a frustum-shaped section 401 with an inner diameter gradually decreasing from top to bottom, and the sprinkler 41 is connected to the lower opening of the frustum-shaped section 401, so that the rainwater in the water collecting chamber 4 can flow into the sprinkler 41 under the action of its own gravity and can be sprayed out through the sprinkler 41.

As shown in fig. 1, the water collecting chamber 4 may have an activated carbon layer 10 therein to filter the water flowing into the sprinkler head 41, so that the rainwater purifying effect may be further improved.

In order to achieve the technical effect that the rotating drum 51 can rotate around the axis thereof, the invention also provides the following technical scheme: as shown in fig. 1, the casing 1 may have a first annular support plate 11 and a second annular support plate 12 therein. The first annular support plate 11 is located above the second annular support plate 12. The aforementioned drum 51 is vertically located between the first annular support plate 11 and the second annular support plate 12. The upper end opening of the drum 51 is opposed to the inner hole of the first annular support plate 11. A plurality of first balls 501 are provided on the upper end surface of the drum 51. The plurality of first balls 501 are evenly distributed in a circle around the center line of the drum 51 on the upper end surface of the drum 51. The lower end face of the first annular supporting plate 11 is provided with a first annular groove matched with the first ball 501. The first annular groove has the technical effect of limiting the first ball 501, and can prevent the first ball 501 from being separated from the first annular groove. The lower end opening of the drum 51 is opposed to the inner hole of the second annular support plate 12. A plurality of second balls 502 are provided on the lower end surface of the drum 51. The plurality of second balls 502 are evenly distributed in a circle around the center line of the drum 51 on the lower end surface of the drum 51. A second annular groove matched with the second ball 502 is arranged on the upper end surface of the second annular supporting plate 12. The second annular groove has the technical effect of limiting the second ball 502, and can prevent the second ball 502 from being separated from the second annular groove. Specifically, the first ball 501 cooperates with the first annular groove to define the upper end of the drum 51, and the second ball 502 cooperates with the second annular groove to define the lower end of the drum 51. When the drum 51 rotates, the first balls 501 at the upper end of the drum 51 rotate around the first annular groove, and the second balls 502 at the lower end of the drum 51 rotate around the second annular groove. Wherein the centerlines of both the first and second annular grooves coincide with the centerline of the drum 51.

The first ball 501 and the second ball 502 also have the technical effect of reducing the frictional resistance during the rotation of the drum 51.

As shown in fig. 1, the aforementioned driving mechanism may include a cylinder and a rack 21 in order to drive the drum 51 to rotate. The lower end of the drum 51 has an annular flange 50. The annular flange 50 has first drive teeth on a sidewall thereof. The piston rod of the cylinder is connected to the rack 21 to drive the rack 21 to reciprocate. The rack 21 engages with a first drive tooth on the annular flange 50 to drive the drum 51 in reciprocating rotation.

Further, the housing 1 may be provided with a limiting groove, and the rack 21 may be slidably disposed in the limiting groove. The cylinder can drive the rack 21 to reciprocate along the limiting groove.

As shown in fig. 1, a third annular support plate 13 may be further disposed inside the casing 1. The third annular support plate 13 is disposed below the filter plate 52. The filter plate 52 is movably disposed on the third annular supporting plate 13 through the elastic member 131, so that when the vibrating rod 521 on the filter plate 52 is impacted by external force, the filter plate 52 also vibrates under the action of the elastic member 131, thereby further improving the atomization effect of the rainwater in the atomization and disinfection chamber 5.

The elastic member 131 may be a compression spring, a flexible rubber, or the like.

Further, as shown in fig. 1, the rainwater purification apparatus 100 having the separation and sedimentation function may further include a water pipe 16 connecting the purified water chamber 6 and the header chamber 4. The water pipe 16 is provided with a water pump 17 for pumping the water in the clean water chamber 6 to the water collecting chamber 4. Therefore, the water in the water purifying chamber 6 can be pumped into the water collecting chamber 4 for filtering and purifying again, so as to further improve the purifying effect of the rainwater.

As shown in fig. 1, a tap 14 may be provided at a water outlet of the clean water chamber 6 to discharge water in the clean water chamber 6 as required.

Further, as shown in fig. 1, a support seat 15 may be disposed at the bottom of the casing 1. The supporting base 15 is provided with a forklift insertion hole 151 so as to facilitate transportation of the rainwater purification apparatus 100 with a separation and deposition function of the present invention to a set position using a forklift.
