[0002] According to my country's meteorological statistics, the number of rainy days in southern China is generally over 100, and in some places it exceeds 200. For example, in the Greater and Lesser Khingan Mountains and Changbai Mountain areas in Northeast China, and south of the Huaihe and Han Rivers in South China, the number of rainy days per year is between 100 and 200.

[0003] Abundant rainwater is a precious water resource. For some factories, rainwater can reduce the use of tap water or groundwater, which can save costs. Collecting rainwater can be put into production or daily use, which is a better choice for enterprises.

[0004] Traditional rainwater harvesting devices simply collect rainwater and then use it directly after simple sedimentation. Generally, factories have large buildings, and the roofs of the buildings can better collect rainwater. The amount of rainwater is huge. If rainwater is collected in a factory, the rainwater will pass through the factory building and remain. Depending on the type of factory building, the rainwater may be mixed with the following impurities: Steel structure workshop: When the roof steel plate is rusted, rainwater will carry rust with it; when the asphalt waterproof roof and rubber sealing strips are aged, rainwater will wash away fine particles; After old concrete roofs or walls weather, rainwater carries cement slurry, sand particles, etc.

[0005] In addition, they also carry some bird droppings, insects, and small bird feathers.

[0006] Some of the above impurities cannot be removed by sedimentation, resulting in incomplete filtration of rainwater and inability to be put into normal use. Summary of the Invention

One end of the auger roller extends to the interior of the fixed shell and the transparent shell, and an opening is provided above this end.

[0009] As a further technical solution of the present invention, the opening side of the auger roller is welded with two guide plates in an inclined manner, and the two guide plates are connected below by an arc shell; The edge of the scraper close to the auger roller is in close contact with the arc shell.

[0010] As a further technical solution of the present invention, a mounting hole is opened in the middle of the fixed shell, and the auger roller is inserted through the mounting hole and fixed to the transparent shell and fixedly connected by bolts.

[0011] As a further technical solution of the present invention, the diameter of the mounting hole is larger than the outer diameter of the auger roller, and a bearing is installed on the outside of the auger roller, and the outer ring of the bearing is installed in the T-shaped sleeve; the T-shaped sleeve is rotatably connected to the mounting hole.

[0012] As a further technical solution of the present invention, the turntable is welded to the T-shaped sleeve or fixedly connected by bolts; the end of the T-shaped sleeve away from the turntable extends to the outside of the fixed housing and is equipped with a gear ring; The gear ring is meshed with the gear, wherein the gear is mounted on the output shaft of the rotating motor; the rotating motor is fixed to the fixed housing via a motor base.

[0013] As a further technical solution of the present invention, a mounting base is integrally provided on the side of the fixed housing close to the factory building; the mounting base is provided with a through hole for the bolt to pass through and to be fixed to the factory building.

In the present invention, when rainwater enters between the fixed housing and the transparent housing, a scraper blade is provided with a plurality of filter mesh holes to scrape the rainwater. This allows the scraper blade to retain the rainwater and scrape away impurities. Since the scraper blade is tilted from the edge of the fixed housing toward the axis, as the scraper blade rotates continuously, impurities on the scraper blade will fall onto the auger roller, which then transfers the impurities out. An impurity transfer pipe is provided at the lower end of the auger roller, and a slag collection box is fixed to the lower end of the impurity transfer pipe. This allows the impurities to be transferred to the slag collection box, achieving solid-liquid separation and further improving the cleanliness of the rainwater. 2.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-10 In an embodiment of the present invention, a rainwater collection and reuse device includes a rainwater collection mechanism 100 installed at a drainage outlet of a factory building 200. The rainwater collection mechanism 100 for filtering rainwater is fixed to the outside of the factory building 200, and a rainwater treatment device 300 is provided below the rainwater collection mechanism 100. The rainwater collection mechanism 100 includes a delivery pipe 5 for delivering rainwater to the rainwater treatment device 300. The upper end of the delivery pipe 5 is connected to a debris removal mechanism 4. The impurity removal mechanism 4 is provided with at least two, and the impurity removal mechanism 4 includes a fixed shell 41 and a transparent shell 42 fixed to each other, wherein the transparent shell 42 has a water inlet, and the lower end of one side of the fixed shell 41 has a water outlet for connecting to the delivery pipe 5; A rotatable turntable 46 is provided inside the fixed housing 41 and the transparent housing 42. A plurality of scrapers 48 are arranged in an annular array on the outer side of the turntable 46 to filter and remove impurities in rainwater. It also includes an auger roller 43 that can filter out impurities from rainwater. One end of the auger roller 43 extends to the interior of the fixed shell 41 and the transparent shell 42, and an opening is provided above this end.

[0031] By adopting the above technical solution, during installation, the rainwater collecting mechanism 100 is installed on the outer wall of the factory building 200, and the rainwater collecting port of the rainwater collecting mechanism 100 is aligned with the pre-discharge port of the factory building 200; when rainwater enters between the fixed shell 41 and the transparent shell 42, the scraper 48 scrapes the rainwater, and a number of filter mesh holes are provided on the scraper 48; in this way, the scraper 48 can retain the rainwater and scrape up impurities; since the scraper 48 is inclined from the edge of the fixed shell 41 to the axis, when the scraper 48 rotates continuously, the impurities on the scraper 48 will fall into the auger roller 43, and the auger roller 43 can then transfer the impurities out; an impurity transmission pipe is provided at the lower end of the auger roller 43, and a slag box is fixed at the lower end of the impurity transmission pipe; in this way, the impurities can be transferred to the slag box, solid-liquid separation is achieved, and the cleanliness of the rainwater is further improved.

[0032] Please see attached picture Figure 6 and Figure 8 In this embodiment, the opening side of the auger roller 43 is welded with two guide plates 44 in an inclined manner, and the two guide plates 44 are connected below by an arc shell 45; The edge of the scraper 48 close to the auger roller 43 is in close contact with the arc-shaped shell 45 .

[0033] By adopting the above technical solution, the two guide plates 44 are arranged in a V-shape, which improves the accuracy of impurities entering the auger roller 43, thereby ensuring that the impurities can be cleaned out.

[0034] In addition, the scraper 48 is also closely connected to the arc-shaped shell 45, which can prevent impurities on the scraper 48 from falling off before reaching the guide plate 44, and ensure that the impurities can still rotate with the scraper 48 when the scraper 48 rotates.

[0035] Please see the attached Figure 7 In this embodiment, a mounting hole is opened in the middle position of the fixed shell 41. The diameter of the mounting hole is larger than the outer diameter of the auger roller 43. This is to facilitate the installation of a bearing on the outside of the auger roller 43. The outer ring of the bearing is installed in the T-shaped sleeve 47. This is to ensure that the T-shaped sleeve 47 can drive the turntable 46 to rotate. The T-shaped sleeve 47 is also rotatably connected to the mounting hole.

[0036] For this reason, the auger roller 43 is fixedly engaged with the transparent housing 42 after penetrating the mounting hole and is fixedly connected by bolts. This can achieve the fixing of the auger roller 43 and avoid the situation of swinging or instability during work.

[0037] In this embodiment, the turntable 46 is welded to the T-shaped sleeve 47 or fixedly connected by bolts; the end of the T-shaped sleeve 47 away from the turntable 46 extends to the outside of the fixed housing 41 and is equipped with a gear ring 49; The gear ring 49 is meshed with the gear 410 , wherein the gear 410 is mounted on the output shaft of the rotating motor 411 ; the rotating motor 411 is fixed to the fixed housing 41 via a motor base 412 .

[0038] By adopting the above technical solution, the rotating motor 411 drives the rotation of the T-shaped sleeve 47 through the matching connection between the gear ring 49 and the gear 410, and the T-shaped sleeve 47 rotates with the turntable 46 equipped with the scraper 48, thereby filtering and discharging impurities in the rainwater.

[0039] In this embodiment, a mounting seat 413 is integrally provided on a side of the fixed housing 41 close to the factory building 200 ; the mounting seat 413 is provided with a through hole for bolts to pass through and for fixing to the factory building 200 .

[0040] The installation of the mounting base 413 enables the fixing of the housing 41 to the factory building, thereby ensuring the stability of the equipment during operation.

[0042] By adopting the above technical solution, multiple water collecting buckets 1 are provided to facilitate the collection of rainwater discharged from the factory; the setting of the connecting pipe 2 can evenly distribute the rainwater. When a certain impurity removal mechanism 4 fails or is blocked, it flows through the connecting pipe 2 to other impurity removal mechanisms 4, thus ensuring normal treatment of the rainwater.

[0044] By adopting the above technical solution, after the impurities are removed, the rainwater enters the sedimentation tank 301 for sedimentation treatment, and the dust impurities or industrial dust it carries are precipitated. Then, it flows into the flocculation tank 302 by overflow for flocculation treatment, thereby further improving the cleanliness of the rainwater; then it is pumped into the water collection tank 304 for storage; when it is needed, it is transported to the water pool 306 through the cooperation of the pump and the water pipe 305 to meet the water needs of the enterprise.

[0045] The working principle of the present invention is as follows: the rainwater collecting mechanism 100 is installed on the outer wall of the factory building 200, and the rainwater collecting port of the rainwater collecting mechanism 100 is aligned with the pre-discharge port of the factory building 200; when rainwater enters between the fixed shell 41 and the transparent shell 42, the scraper 48 scrapes the rainwater, and a plurality of filter mesh holes are provided on the scraper 48; in this way, the scraper 48 can retain the rainwater and scrape up impurities; because the scraper 48 is inclined from the edge of the fixed shell 41 to the axis, when the scraper 48 rotates continuously, the impurities on the scraper 48 will fall into the auger roller 43, and the auger roller 43 can then transfer the impurities out; the lower end of the auger roller 43 is provided with an impurity transfer pipe, and the lower end of the impurity transfer pipe is fixed with a slag collecting box; in this way, the impurities can be transferred to the slag collecting box, thereby realizing solid-liquid separation; After the impurities are removed, the rainwater enters the sedimentation tank 301 for sedimentation treatment, and the dust impurities or industrial dust it carries are precipitated. Then it flows into the flocculation tank 302 by overflow for flocculation treatment, further improving the cleanliness of the rainwater; it is then pumped into the water collection tank 304 for storage; when it is needed, it is transported to the water pool 306 through the cooperation of the pump and the water pipe 305 to meet the water needs of the enterprise.
