As shown in fig. 1, the rainwater recycling device 10 of the present invention includes a rainwater pipe 100, an initial drainage bucket 200 and a rainwater collecting tank 300, wherein the rainwater pipe 100 is connected to the initial drainage bucket 200 and the rainwater collecting tank 300, respectively, and the rainwater pipe 100 is used for guiding rainwater on a roof W to the initial drainage bucket 200 and the rainwater collecting tank 300.
The present invention is applicable to rainwater collection in other large-area areas such as sloping fields and squares, as well as rainwater collection in roof W, and will be described below by taking rainwater collection in roof W as an example.
The initial drainage bucket 200 provided by the invention is used for collecting rainwater collected on the roof W at the initial stage. The roof W is generally attached with a large amount of unclean substances such as dust and impurities, and has the effect of cleaning the roof W when the roof W is flushed by rainwater in an initial stage, and a large amount of dust and impurities are flushed and run away along with the rainwater. Therefore, the rainwater collected in the initial stage is not suitable for direct recycling. The invention is provided with the initial drainage barrel 200, and the rainwater collected in the initial stage is guided to the initial drainage barrel 200 through the rainwater pipe 100 to finish initial rainwater drainage, and then the rainwater which can be directly utilized is guided to the rainwater collecting tank 300 through the rainwater pipe 100, and can be directly utilized after being pumped by a booster pump.
Specifically, as shown in fig. 1 to 3, the initial flow-discarding bucket 200 includes a flow-discarding bucket body 210 and a floating disc 220, the rain pipe 100 is connected to the flow-discarding bucket body 210, the floating disc 220 is disposed in the flow-discarding bucket body 210, and the floating disc 220 has buoyancy and can always float above the water surface in the flow-discarding bucket body 210.
First, rainwater enters the drainage bucket 210 along the rainwater pipe 100, and as the water level of the drainage bucket 210 increases, the floating disc 220 also increases gradually (as shown in fig. 2), until the drainage bucket 210 is full of rainwater, the floating disc 220 closes the drainage bucket 210 (as shown in fig. 3), so that rainwater cannot enter the drainage bucket 210 any more. The rainwater then enters the rainwater collecting tank 300 along the other outlet of the rainwater pipe 100.
As shown in fig. 1, the initial drainage bucket 200 and the rainwater collecting tank 300 of the present invention are located at a lower position relative to the roof, and rainwater collected on the roof can be directly guided into the initial drainage bucket 200 or the rainwater collecting tank 300 by gravity in the rainwater pipe 100.
In detail, referring to fig. 1 and 4, the rain water pipe 100 is vertically disposed as a whole to connect the roof W and the initial drainage bucket 200 and the rain water collecting tank 300, so that the rain water can be directly guided from the roof W to the initial drainage bucket 200 or the rain water collecting tank 300 by gravity. The rain pipe 100 comprises a main pipe body 110, a drainage pipe body 120 and a collecting pipe body 130, wherein the drainage pipe body 120 and the collecting pipe body 130 are respectively connected with the main pipe body 110, the main pipe body 110 is connected with a roof W, the drainage pipe body 120 is connected with a drainage barrel body 210 of the initial drainage barrel 200, and the collecting pipe body 130 is connected with a rain water collecting tank 300.
In more detail, the main pipe body 110 and the reject pipe body 120 are vertically arranged, and at an initial stage, rainwater enters the reject pipe body 120 along the main pipe body 110, and finally fills the initial reject bucket 200. The collecting pipe body 130 includes a first collecting pipe body 131 and a second collecting pipe body 132, both ends of the first collecting pipe body 131 are connected to one ends of the main pipe body 110 and the second collecting pipe body 132, respectively, and the other end of the second collecting pipe body 132 is connected to the rainwater collecting tank 300. The first collecting pipe body 131 is vertically disposed with respect to the main pipe body 110, that is, the first collecting pipe body 131 is horizontally disposed. The second collecting pipe body 132 is parallel to the main pipe body 110, i.e., the second collecting pipe body 132 is vertically disposed.
As shown in fig. 2 and 3, the waste stream bucket 210 includes a step portion 211, and the step portion 211 corresponds to the floating disc 220. Preferably, sealing members 230 are respectively disposed between the step portion 211 of the water outlet and the water discharge barrel 210 of the water discharge pipe 120 of the rainwater pipe 100 and the floating plate 220.
In the rainwater collecting process, as the initial rainwater enters, the water level in the reject flow barrel 210 rises, the float plate 220 rises, when the water level reaches the closed state, the water outlet of the float plate 220 and the reject flow barrel 120 and the step 211 arranged on the upper wall of the reject flow barrel 210 are in a sealing state through the action of the sealing member 230, the rainwater in the rainwater pipe 100 cannot enter the initial reject flow barrel 200 through the reject flow barrel 120, the rainwater later causes the rainwater level in the pipeline of the reject flow barrel 120 positioned below to rise, and the rainwater enters the first collecting pipe 131 of the transversely arranged collecting pipe 130 and finally enters the rainwater collecting tank 300 through the second collecting pipe 132.
The sealing member 230 is made of, for example, ultraviolet aging resistant rubber, so as to form an effective seal between the water outlet of the waste pipe 120 and the float plate 220 and between the step 211 and the float plate 220, and prevent a large amount of clean rainwater from leaking through the gaps between the water outlet of the waste pipe 120 and the float plate 220 and between the step 211 and the float plate 220. In addition, the drainage pipe 240 is further disposed on the drainage bucket 210, and the drainage pipe 240 is generally disposed at a position below the drainage bucket 210.
As shown in fig. 2 and 3, in an embodiment of the present invention, the float 220 has a central water passing hole 221, and the central water passing hole 221 corresponds to a nozzle at a water outlet of the reject pipe 120 of the downspout 100. The invention sets the central water through hole 221 corresponding to the water outlet of the waste flow pipe 120 in the waste flow barrel 210 on the floating disc 220, so that when the waste flow barrel 210 is full and the floating disc 220 floats and forms a seal with the waste flow pipe 120 and the step 211, the static pressure in the waste flow pipe 120 can be effectively transferred into the waste flow barrel 210, the pressure in the waste flow barrel 210 is increased, the upper and lower pressures of the floating disc 220 are consistent, and the sealing between the floating disc 220 and the waste flow pipe 120 and the sealing between the floating disc and the step 211 are more effectively realized, so that the sealing failure caused by unstable pressure is avoided.
As shown in fig. 1 and 5, the rainwater recycling apparatus 10 of the present invention further includes a sand removal filter device 400, and the sand removal filter device 400 is connected to the main pipe body 110 of the rainwater pipe 100. In the initial stage, when rainwater is flushed from the roof W, a large amount of small impurities such as dust, bacteria and the like originally on the roof W are carried, and large impurities such as sand, leaves and the like are also carried, so that a large amount of large impurities possibly block a water flow pipeline, and the device is invalid. The sand removal and filtration device 400 is arranged to remove massive impurities such as sand, leaves and the like in the rainwater, so that the normal operation of the device is ensured.
Specifically, the desanding filter device 400 includes a desanding part 410 and a filtering part 420, the desanding part 410 and the filtering part 420 being disposed up and down, the desanding part 410 being disposed above the filtering part 420. According to the above, the main pipe body 110 is vertically arranged, and the sand removal filtering device 400 composed of the sand removal portion 410 and the filtering portion 420 is also vertically arranged, wherein the sand removal portion 410 and the main pipe body 110 have a first connection channel P1 therebetween, and the filtering portion 420 and the main pipe body 110 have a second connection channel P2 therebetween. The main pipe 110 includes a control pipe 110A between the first connection path P1 and the second connection path P2, where a valve 110B is disposed on the control pipe 110A, and rainwater can be controlled to flow downward directly on the main pipe 110 by the control valve 110B, or flow downward after sand removal and filtration by the sand removal and filtration device 400.
For example, in the initial stage, since a large amount of bulk impurities are entrained in the rainwater, the valve 110B is closed, the rainwater enters the degritting part 410 from the first connection path P1 between the main pipe body 110 and the degritting part 410 to degritting, and then is filtered by the filtering part 420 under the degritting part 410, and the degritted and filtered rainwater returns to the main pipe body 110 through the second connection path P2 between the filtering part 420 and the main pipe body 110, and finally flows to the initial reject tub 200 or the rainwater collecting tank 300. After a period of time has elapsed and the rainwater has reached the desired requirements, the valve 110B may be opened, that is, the rainwater is not forced to pass through the sand removal filter device 400, and the flow rate of the rainwater in the pipe may be increased, thereby improving the recovery efficiency.
Of course, in the present invention, the areas of the sand removing part 410 and the filtering part 420 are large enough, and the head loss is controlled within 0.1-0.2 m, so that the water passing capability is not affected.
Preferably, in an embodiment of the present invention, a slag discharging valve 430 is disposed below the sand removing and filtering device 400, that is, below the filtering portion 420, so as to conveniently discharge the large-sized impurities discharged and filtered, thereby ensuring the effective operation of the sand removing and filtering device 400.
The volume of the initial flow-discarding barrel 200 is determined according to the area of the collecting roof and the flow-discarding coefficient.
The volume of the general reject stormwater is as follows:
V 1 -volume of reject stormwater in m 3;
h 1, namely the thickness of the discarded rainwater is usually 2.5-4 mm, and is usually 4mm;
F-drainage area of a rain bucket, where a rain bucket (such as the rain bucket 500 shown in FIG. 4) is attached to the top of a rain pipe, the drainage area is usually determined according to the drainage capacity of the rain bucket, the design rainfall, and the like.
A great deal of experimental study on the drainage capacity of the rain water bucket is carried out in China, the drainage capacity of the rain water bucket is increased gradually along with the height of the rain water pipe, for example, when the height of the rain water pipe is increased from 6m to 12m, the drainage capacity of the rain water bucket is increased by about 40%, in addition, the submerged depth of the rain water bucket is also an important factor for increasing the drainage capacity of the rain water bucket, and of course, all the factors have limit values, and the value in engineering is always 50% of the experimental value so as to ensure safety. The following table 1 shows the drainage capacity of a gravity type rainwater hopper commonly used in China, and the drainage capacity of a matched rainwater pipe is shown in the following table 2. For siphon rainwater, the drainage capacity of the rainwater hopper is the maximum value of the gravity rainwater hopper, and the drainage of the rainwater pipe is calculated according to the full pipe flow. However, the collection of the rainwater recycling device is determined according to the protection area of the rainwater hopper.
Table 1 87 (79) design drainage Capacity of rain bucket
| Caliber (mm) | 75 | 100 | 150 | 200 |
| Leakage flow (L/s) | 6~8 | 12～16 | 26～36 | 40～56 |
Table 2 design drainage capacity of the downspout
| Nominal diameter (mm) | 75 | 100 | 150 | 200 | 250 | 300 |
| Drainage flow (L/s) | 10~12 | 19~25 | 42~55 | 75~90 | 135~155 | 220~240 |
For a rainwater hopper with DN100, the design drainage capacity is 15L/s, and the design storm intensity of roof rainwater is 100mm/h calculated according to a certain rainwater storm formula, then the drainage catchment area of the rainwater hopper is F1= (15 x 3600/1000)/(1 x 100/1000) =540 m 2.
According to the principle of a rainwater collection system, the rainwater collection period is 1a according to a local storm intensity formula, the rainfall duration is the rainfall capacity of 60min, h 2 is the economic and reasonable rainwater design recovery rainfall thickness, and the rainfall thickness is calculated through the storm intensity formula, for example, h 2 =35 mm in a certain place.
The rainwater pipe is connected with 3 rainwater hoppers, and the drainage area of the rainwater pipe is f=540×3=1620 m 2. The effective volume of the initial flow discarding barrel body of the rainwater recycling device corresponding to the rainwater pipe is as follows:
V1=h1F=（4/1000）x1620=6.48m3
the effective volume of the rainwater collecting tank is as follows:
V2=（（35-4）/1000）x1620=50.22m3
when the rainwater pipe is connected with only one rainwater hopper, the drainage volume of the drainage barrel body and the recovery volume of the rainwater collecting tank are respectively 2.16m 3 and 16.74m 3.
According to the above, the effective volumes of the initial drainage bucket and the rainwater collecting pool are calculated and determined according to the local rainfall statistical data, the storm intensity formula, the rainwater collecting thickness and the like, and a series of products are formed for application in different areas.
Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
