Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rain and sewage separation, in particular to a rain and sewage mixed flow intelligent separation device. BACKGROUND

[0002] With the development of urbanization, small cities have gradually developed into medium and large cities, and the communities built many years ago have become old communities. Due to the constraints of the times, the old communities have the problem of backward supporting facilities, such as no gas supply, mixed and random sewage drainage, etc.

[0003] With the advancement of old community renovation projects, many old communities have realized gas supply, but sewage renovation is still a problem. Generally, the balcony drainage pipe and the roof rainwater drainage pipe of the old community usually share the same pipe, which drains rainwater and balcony domestic sewage to the ground of the community, causing rain and sewage mixing.

[0004] During the renovation process, due to the aging of the old community buildings, adding pipes by slotting the building structure will cause damage to the building structure, and the terrain of the public area of the old community is narrow, so it is difficult to add pipes on a large scale for each residential building. If the rain and sewage mixed flow pipe is directly connected to the surface sewer of the community, it will cause water pollution of the surface water system connected directly to the sewer, and even cause eutrophication or odor of the urban river water body. If the rain and sewage mixed flow pipe is directly connected to the municipal sewage pipe, rainwater will be discharged into the sewage pipe, especially in southern cities, the rainy season is long, and such treatment method will cause serious pressure on the urban sewage drainage system and sewage treatment system, and in serious cases, rain and sewage mixed flow pipe sewage will backflow, affecting the life of residents.

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0033] Embodiment 1

[0034] Referring to Figure 1 as shown:

[0035] The present application provides a rain and sewage mixed flow intelligent diversion device, comprising a rain and sewage mixed flow pipe 10 and a rain and sewage diversion bin buried underground.

[0036] One end of the rain and sewage mixed flow pipe 10 is connected with a drainage port of a roof, and the other end of the rain and sewage mixed flow pipe 10 is in communication with the rain and sewage diversion bin.

[0037] A half partition 75 and a full partition 62 are arranged inside the rain and sewage diversion bin, and the inside of the rain and sewage diversion bin is sequentially divided into a first rainwater diversion chamber 70, a sewage diversion chamber 50 and a second diversion chamber 60 from left to right, so that the first rainwater diversion chamber 70 and the second diversion chamber 60 are respectively located on the two sides of the sewage diversion chamber 50. The sewage diversion chamber 50, the first rainwater diversion chamber 70 and the second diversion chamber 60 are respectively in communication with the rain and sewage mixed flow pipe 10.

[0038] The rain and sewage shunting assembly is installed in the rain and sewage mixed flow pipe 10, the sewage shunting chamber 50, the first rainwater shunting chamber 70 and the second shunting chamber 60, and the rain and sewage flowing through the rain and sewage mixed flow pipe 10 are respectively introduced into the sewage shunting chamber 50, the first rainwater shunting chamber 70 and the second shunting chamber 60. Meanwhile, the sewage shunting chamber 50 is communicated with the municipal sewage pipe, and the first rainwater shunting chamber 70 and the second shunting chamber 60 are communicated with the urban surface drainage channel, so that the classified discharge of rainwater and sewage is realized, the environment of the old community is improved, and the pressure of the urban sewage treatment system is reduced.

[0039] The rain and sewage shunting assembly is composed of a controller, a vertical opening and closing plate 72, and a water flow sensor 11, a first electric valve 12, a third electric valve 21, a second electric valve 41, a sewage liquid level detector 52, an electric telescopic rod 71 and a first rainwater liquid level detector 74 which are electrically connected with the controller.

[0040] The water flow sensor 11 is installed at the connection between the rain and sewage mixed flow pipe 10 and the roof drainage port. When the rain falls on the roof of the old community, the rainwater flows to the roof drainage port and can be detected by the water flow sensor 11, so that the rainwater entering the rain and sewage mixed flow pipe 10 is determined.

[0041] A tee joint is arranged at the water outlet end of the rain and sewage mixed flow pipe 10, the tee joint is arranged in the vertical direction, and two through holes of the tee joint constitute a drainage channel in the vertical direction. The water outlet end of the rain and sewage mixed flow pipe 10 is connected with the through hole at the top of the tee joint. A first rainwater collecting pipe 30 is arranged at the top of the first rainwater shunting chamber 70, the first rainwater collecting pipe 30 is arranged in the vertical direction, the top of the first rainwater collecting pipe 30 is connected with the through hole at the bottom of the tee joint, and the bottom of the first rainwater collecting pipe 30 is communicated with the working cavity of the first rainwater shunting chamber 70. The first electric valve 12 is installed at the connection between the first rainwater collecting pipe 30 and the tee joint. In actual work, when the controller receives the rainwater entering the rain and sewage mixed flow pipe 10 detected by the water flow sensor 11, the controller controls the first electric valve 12 to open, so that the rainwater of the rain and sewage mixed flow pipe 10 can directly enter the working cavity of the first rainwater shunting chamber 70.

[0042] Due to the semi-partition 75 for separating the first rainwater diversion chamber 70 and the sewage diversion chamber 50 is arranged in the rainwater and sewage diversion warehouse, and the height of the semi-partition 75 is lower than the height of the first rainwater diversion chamber 70, generally, the height of the semi-partition 75 is set to be half of the working cavity height of the first rainwater diversion chamber 70. The vertical opening and closing plate 72 is vertically installed in the first rainwater diversion chamber 70, and the top end of the vertical opening and closing plate 72 is hinged to the top of the working cavity of the first rainwater diversion chamber 70. The electric telescopic rod 71 is also installed at the top of the working cavity of the first rainwater diversion chamber 70, and the telescopic rod of the electric telescopic rod 71 is connected with one side of the vertical opening and closing plate 72, and the other side of the vertical opening and closing plate 72 abuts against one side of the semi-partition 75.

[0043] Through such arrangement, the telescopic rod of the electric telescopic rod 71 and the top of the working cavity of the first rainwater diversion chamber 70, and the connection side of the vertical opening and closing plate 72 form a triangular structure, which has stability, and when the first rainwater diversion chamber 70 is full of rainwater, the extrusion force of the rainwater on the vertical opening and closing plate 72 also makes the vertical opening and closing plate 72 abut against the semi-partition 75 more closely, so as to avoid the rainwater entering the sewage diversion chamber 50, and improve the diversion effect of the equipment on rainwater and sewage. In addition, in order to ensure the working effect of the electric telescopic rod 71, the inside of the electric telescopic rod 71 is waterproof treated, so as to ensure the stability of the working.

[0044] Before the controller sends the telescopic instruction to the electric telescopic rod 71, the telescopic rod of the electric telescopic rod 71 is in the retracted state, at this time, the vertical opening and closing plate 72 and the semi-partition 75 are in the separated state, so that the first rainwater diversion chamber 70 and the sewage diversion chamber 50 are in the connected state. At the same time, the first rainwater drainage port 73 is arranged in the first rainwater diversion chamber 70, the position of the first rainwater drainage port 73 in the vertical direction is higher than the height of the top of the semi-partition 75, and the first rainwater drainage port 73 is connected with the urban surface drainage channel. The bottom of the working cavity of the sewage diversion chamber 50 is lower than the bottom of the working cavity of the first rainwater diversion chamber 70, that is, the sewage diversion chamber 50 is deeper than the first rainwater diversion chamber 70, and the sewage drainage port 51 is arranged in the sewage diversion chamber 50, the position of the sewage drainage port 51 is flush with the bottom of the working cavity of the first rainwater diversion chamber 70, and the sewage drainage port 51 is connected with the municipal sewage drainage pipeline.

[0045] Through such a setting, when the rainwater enters the first rainwater diversion chamber 70 along the rain sewage mixed flow pipe 10, the rainwater will first be stored in the first rainwater diversion chamber 70, and then when the rainwater overflows the top of the half partition 75, it will enter the sewage diversion chamber 50. This makes it clear that when there is intermittent light rain, the amount of rainwater is not enough to cause the water level in the sewage diversion chamber 50 to rise above the half partition 75, indicating that the amount of rainwater is not large at this time, and the discharge pressure of the working cavity of the sewage diversion chamber 50 is also not large. In the case of small amount of rainwater, the rainwater will bring the dust and debris on the roof into the first rainwater diversion chamber 70 or the sewage diversion chamber 50, and at this time the rainwater does not need to be discharged to the urban surface drainage pipeline, and it is more appropriate to be discharged to the municipal sewage pipeline by the sewage diversion chamber 50, and the appropriate amount of rainwater entering the municipal sewage pipeline can achieve the effect of cleaning the municipal sewage pipeline.

[0046] The full partition 62 is used to separate the sewage diversion chamber 50 and the second diversion chamber 60, and after separation, the sewage diversion chamber 50 and the second diversion chamber 60 are in two completely independent cavities. The sewage liquid level detector 52 is installed on the full partition 62, and the position of the sewage liquid level detector 52 on the full partition 62 is flush with the top of the half partition 75. The top of the second diversion chamber 60 is provided with a second rainwater collecting pipe 20 in communication therewith, and the middle through hole of the three-way pipe joint is in communication with the second rainwater collecting pipe 20. A sewage inlet pipe 40 is provided at the top of the sewage diversion chamber 50 and is in communication therewith, and the sewage inlet pipe 40 is in communication with the middle of the second rainwater collecting pipe 20. The second electric valve 41 is installed at the communication between the sewage inlet pipe 40 and the sewage diversion chamber 50, and the third electric valve 21 is installed at the communication between the second rainwater collecting pipe 20 and the second diversion chamber 60.

[0047] Through such a setting, when the sewage liquid level detector 52 detects the sewage in the sewage diversion chamber 50, it indicates that the water level height of the sewage in the sewage diversion chamber 50 will soon exceed the half partition 75 and enter the first rainwater diversion chamber 70. It indicates that at this time, not only rainwater enters the first rainwater diversion chamber 70 from the first rainwater collecting pipe 30, but also rainwater enters the sewage diversion chamber 50 from the sewage inlet pipe 40, representing that the amount of rainwater on the roof is large. At this time, the controller issues an extension command to the electric telescopic rod 71, and the extension rod of the electric telescopic rod 71 pushes the vertical opening and closing plate 72 against the half partition 75, completely separating the first rainwater diversion chamber 70 and the sewage diversion chamber 50. At the same time, according to the information provided by the water flow sensor 11 and the sewage liquid level detector 52, the controller starts to control the second electric valve 41 to close, so that the rainwater completely enters the urban surface drainage channel from the first rainwater diversion chamber 70 and is discharged to the urban water system.

[0048] In actual application, the volume of the area from the bottom of the working chamber of the sewage diversion chamber 50 to the sewage liquid level detector 52, and the speed of the sewage diversion chamber 50 for external drainage are in a certain ratio with the maximum discharge amount of the building balcony sewage. In order to ensure the rationality of the ratio, when setting the capacity of the sewage diversion chamber 50, the time of the balcony sewage of the users in the community is investigated in advance, which is generally the laundry and mopping sewage of the balcony. According to the investigation results, the simultaneous drainage amount of the 8 kg washing machine of 3 to 4 households of the building where the rainwater and sewage mixed flow pipe 10 is located is selected as the capacity reference value of the sewage diversion chamber 50, and the speed of the sewage diversion chamber 50 for external drainage is 2 to 3 times of the sewage entering the sewage diversion chamber 50.

[0049] This ensures the accuracy of the sewage liquid level detector 52, that is, in general, only when the sewage enters the sewage diversion chamber 50, the water level of the sewage will not rise to the position of the sewage liquid level detector 52, so as to ensure that the sewage liquid level detector 52 will not transmit signals to the controller. In addition, in the controller, a control program is set, when the controller does not receive the information of the water flow sensor 11, but receives the information of the sewage liquid level detector 52, the controller will not control the second electric valve 41 to close, but only control the electric telescopic rod 71 to push the vertical opening and closing plate 72 to abut against the half partition plate 75, so as to completely separate the first rainwater diversion chamber 70 and the sewage diversion chamber 50, and remind the background personnel to timely dredge the sewage diversion chamber 50, so as to ensure the accurate sewage discharge of the sewage diversion chamber 50, and improve the effect of the equipment on the rainwater and sewage classification discharge.

[0050] The third electric valve 21 is installed on the second rainwater collecting pipe 20 and located at the communication between the second diversion chamber 60 and the second rainwater collecting pipe 20. The bottom of the working chamber of the first rainwater diversion chamber 70 is flush with the bottom of the working chamber of the second diversion chamber 60. The first rainwater liquid level detector 74 is installed at the first rainwater drainage port 73 in the first rainwater diversion chamber 70. The second rainwater drainage port 61 is arranged in the second diversion chamber 60 and communicates with the urban surface drainage channel. The first rainwater drainage port 73, the second rainwater drainage port 61 and the sewage drainage port 51 are sequentially distributed from top to bottom along the vertical direction.

[0051] Through such a setting, when the first rainwater liquid level detector 74 detects rainwater, it indicates that the water level in the first rainwater diversion chamber 70 will soon overflow the first rainwater drainage port 73, which indicates that the amount of rainwater is large at this time. In order to ensure the rainwater drainage effect, the controller opens the third electric valve 21, and when the rainwater fills the first rainwater diversion chamber 70, the second electric valve 41 has been closed at this time, and the excess water can enter the second diversion chamber 60 and then enter the urban surface drainage channel through the second diversion chamber 60, thereby improving the effect of the equipment on rainwater diversion.

[0052] Further comprising a first silt discharge pipe 76 and a second silt discharge pipe 63; the bottom of the working cavity of the first rainwater diversion chamber 70 is communicated with one end of the first silt discharge pipe 76, the other end of the first silt discharge pipe 76 is communicated with the bottom of the working cavity of the sewage diversion chamber 50, and the first silt discharge pipe 76 is provided with a first silt discharge valve 761. The bottom of the working cavity of the second diversion chamber 60 is communicated with one end of the second silt discharge pipe 63, the other end of the second silt discharge pipe 63 is communicated with the bottom of the working cavity of the sewage diversion chamber 50, and the second silt discharge pipe 63 is provided with a second silt discharge valve 631.

[0053] Through such an arrangement, during daily maintenance, the precipitates in the first rainwater diversion chamber 70 and the second diversion chamber 60 can be flushed into the sewage diversion chamber 50 by opening the valves on the first silt discharge pipe 76 and the second silt discharge pipe 63, so that the first rainwater diversion chamber 70 and the second diversion chamber 60 are more convenient to clean, the convenience of daily maintenance of the equipment is improved, and the effect of rainwater diversion of the equipment is always consistent.

[0054] Further comprising a first silt discharge pipe 76 and a second silt discharge pipe 63; the bottom of the working cavity of the first rainwater diversion chamber 70 is communicated with one end of the first silt discharge pipe 76, the other end of the first silt discharge pipe 76 is communicated with the bottom of the working cavity of the sewage diversion chamber 50, and the first silt discharge pipe 76 is provided with a first silt discharge valve 761. The bottom of the working cavity of the second diversion chamber 60 is communicated with one end of the second silt discharge pipe 63, the other end of the second silt discharge pipe 63 is communicated with the bottom of the working cavity of the sewage diversion chamber 50, and the second silt discharge pipe 63 is provided with a second silt discharge valve 631.

[0055] The above merely describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
