Description

Technical Field

[0001] The utility model relates to the field of rainwater collection and purification, in particular to an intelligent rainwater collection and purification device. Background Art

[0002] With the growth of people's environmental awareness and the increase in water demand, people have begun to pay attention to the use of rainwater. Rainwater collection can be used to alleviate urban water pressure, reduce water waste, and make full use of recyclable resources. The existing rainwater collection device collects rainwater in a trough or a water basin, and then filters it through a filtration facility. When it rains, while collecting rainwater and filtering it, if the rain is too heavy, the filtration speed will not keep up with the rainwater access speed, which may cause full load and inability to drain in time. At the same time, it cannot remind the staff that the rainwater is currently full, and the staff cannot understand whether the full load is caused by heavy rain or blockage. For this reason, we propose an intelligent rainwater collection and purification device. Utility Model Content

[0024] Furthermore, the floating switch includes a circular tube 17, a contact switch 18 and a floating assembly. The circular tube 17 is fixedly mounted on the bottom inner wall of the water receiving box 4, the contact switch 18 is fixedly mounted on the top inner wall of the circular tube 17, and the floating assembly is arranged inside the circular tube 17.

[0025] Furthermore, the floating assembly includes a movable plate 20, a slide rod 21 and a float 22. Two side grooves 19 are provided on the circular tube 17. The movable plate 20 is movably arranged inside the circular tube 17, and a slide rod 21 is fixedly installed on the side of the movable plate 20 corresponding to the position of the side groove 19. The slide rod 21 is slidably engaged with the side groove 19. The slide rod 21 on one side extends to the outside of the circular tube 17, and a float 22 is fixedly installed at the end thereof. When there is too much rain, causing the water level inside the water receiving box 4 to rise, the float 22 will float upward. When the movable plate 20 follows the float and contacts the contact switch 18, the solenoid valve 5 is opened at this time to drain the inside of the water receiving box 4 to prevent water accumulation. In actual use, the contact switch 18 can be electrically connected to the alarm system. When the contact switch 18 is started, the alarm is activated to allow the staff to go and observe. At the same time, it can be understood whether the connecting pipe 6 or the filter box 7 is blocked, resulting in the inability to guide or filter rainwater normally.

[0026] Furthermore, an inner wall groove 1 8 and an inner wall groove 2 10 are provided on the inner wall of the filter box 7. A filter screen 9 is inserted into the interior of the inner wall groove 1 8, and a filter assembly is inserted into the interior of the inner wall groove 2 10. The filter screen 9 is a filter screen with diamond-shaped filter holes, and the filter hole diameter is one centimeter. The filter screen 9 is used to filter larger debris such as tree branches and liquids under the rainwater belt, and a pull-out filter assembly and filter screen 9 are provided to facilitate cleaning of the interior of the filter box 7, the filter screen 9 and the filter assembly.

[0027] Furthermore, the filter assembly includes a filter frame 11, a metal hollow partition 12, a gravel layer 13, an activated carbon adsorption layer 14, a zeolite adsorption layer 15 and a ceramsite adsorption layer 16. Four layers of metal hollow partitions 12 are fixedly installed inside the filter frame 11. Each layer of metal hollow partition 12 is respectively covered with a gravel layer 13, an activated carbon adsorption layer 14, a zeolite adsorption layer 15 and a ceramsite adsorption layer 16.

[0028] Furthermore, the thickness of the zeolite adsorption layer 15 is 12 cm, and the thickness of the ceramsite adsorption layer 16 is 20 to 25 cm respectively. The particle size of the ceramsite in the ceramsite adsorption layer 16 is 5 to 10 mm, and fine honeycomb-shaped micropores are formed inside it, which has a good adsorption effect on pollutants. The zeolite also has many pores, uniform tubular channels and pores with a large internal surface area, so it has unique adsorption, screening, exchange of anions and cations and catalytic properties. It can absorb ammonia nitrogen, organic matter and heavy metal ions in water.

[0029] Working principle: Place the inclined plate 1 on the top of the house. When it rains, the rainwater slides downward along the slope of the triangular groove 3 and finally falls into the inside of the water receiving box 4. Then it enters the inside of the filter box 7 along the connecting pipe 6. After the larger debris is filtered out by the filter mesh 9, it is filtered along the gravel layer 13, the activated carbon adsorption layer 14, the zeolite adsorption layer 15 and the ceramsite adsorption layer 16, and finally discharged through the pipe connected to the bottom of the filter box 7.
