Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment devices, in particular to a vertical flow sedimentation structure and a treatment pool using the same. Background Art
[0002] In the field of sewage treatment technology, sewage is usually mixed with solid waste, and activated sludge is produced during the biological treatment process. In order to purify sewage, solid-liquid separation is performed, and a common separation method is sedimentation. Through sedimentation, the solid suspended matter can be gathered in the lower part of the tank body, and the upper part of the tank body is the supernatant.
[0003] For example, in a treatment tank, sewage can enter from the upper part of the treatment tank or from the lower part of the treatment tank. In order to achieve better sedimentation effect, sewage should be avoided from entering directly from the upper part of the treatment tank. If sewage enters from the upper part of the treatment tank, the solids carried by the incoming water will mix with the supernatant on the upper part of the tank body, and the supernatant is also collected at the upper part of the treatment tank. If water is not only entering from the upper part of the treatment tank, but also collected from the upper part of the treatment tank, it will also cause short-circuiting of sewage and poor sedimentation effect.
[0004] The common practice now is to let water in from the bottom of the treatment pool, and then collect the supernatant by overflow at the top of the treatment pool. However, the existing pipeline layout cannot fully utilize the space of the treatment pool. The water inlet pipeline at the bottom of the treatment pool and the collection device at the top need to be built separately, which has a high construction cost and a large load on the device for collecting the supernatant. At the same time, the method of letting water in from the bottom of the treatment pool needs to overcome the water pressure in the pool, and the sewage pump needs to consume more electricity.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0028] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0029] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0031] In the sewage treatment related technologies, sedimentation tank is an important part of the sewage treatment system. The sedimentation tank settles the suspended matter in the sewage through physical action to achieve the purpose of sewage purification. The solid suspended matter in the sewage mainly includes mud, organic matter, activated sludge produced during biological treatment, and insoluble precipitates formed by adding chemical agents. In the sewage treatment tank, mainly the sedimentation tank, the solid suspended matter is deposited at the bottom of the treatment tank through gravity sedimentation, and the supernatant can be obtained at the top of the treatment tank.
[0032] In order to improve the sedimentation efficiency, the method of water intake from the bottom of the treatment tank is generally adopted, and the supernatant is collected by overflowing the tank body at the top of the treatment tank. Water intake from the bottom and overflow from the top can extend the flow path of sewage and promote the sedimentation of suspended matter, but the layout of the water inlet pipe position is relatively complicated, and the internal space of the treatment tank cannot be fully utilized. In addition, when water is intake from the bottom of the treatment tank, the water pressure at the bottom of the treatment tank is greater, and the sewage pump of the water inlet pipe needs to consume more electricity to meet the transportation of sewage.
[0033] Reference Figure 1 As shown, a vertical flow sedimentation structure of an embodiment of the utility model comprises a guide tube 100 and a plurality of water collecting grooves 200. The guide tube 100 is arranged vertically, and a water inlet is arranged at the upper part of the guide tube 100, and a water outlet is arranged at the lower part; a plurality of water collecting grooves 200 are distributed around the guide tube 100, and the plurality of water collecting grooves 200 are interconnected and communicated, and at least one water collecting groove 200 is connected to the guide tube 100, and the water collecting grooves 200 are arranged horizontally.
[0034] At least one water collection trough 200 is connected to the guide tube 100, so the water collection trough 200 can be fixed to the treatment tank without the need for an additional support structure to fix and support the guide tube 100. The water collection trough 200 is directly used to support the guide tube 100, that is, the water collection trough 200 and the guide tube 100 are of intensive design. The water collection trough 200 and the guide tube 100 are connected, and the water collection trough 200 and the guide tube 100 can be installed at the same time, which makes the construction of the treatment tank more convenient. There are multiple water collection troughs 200, which can make full use of the internal space of the treatment tank, increase the overflow collection points of the supernatant at multiple locations, and reduce the load of a single water collection trough 200.
[0035] When in use, sewage enters from the water inlet at the top of the guide tube 100. The guide tube 100 is arranged vertically. Under the action of gravity, the sewage moves toward the bottom of the guide tube 100 and enters the bottom of the treatment tank from the water outlet. Although the sewage enters from the top of the treatment tank through the guide tube 100, it can be introduced into the bottom of the treatment tank. When water enters from the top of the guide tube 100, the sewage pump does not need to overcome the water pressure in the tank, and consumes less electric energy. It can also introduce sewage into the bottom of the treatment tank through the guide tube 100, which will not cause sewage short-flow and ensure good sedimentation effect. The sewage flows from the guide tube 100 into the bottom of the treatment tank, and then overflows into the sump 200. The sewage flows downward first and then upward, and the flow direction is reversed. The kinetic energy of the suspended matter flowing with the sewage is consumed at the reversal point. Combined with the action of gravity, the sedimentation of the suspended matter is promoted, so the sedimentation efficiency can also be improved.
[0036] It is understandable that the plurality of water collecting grooves 200 are distributed in a crisscross pattern.
[0037] The water collecting trough 200 can be a straight trough body, which is crisscrossed and connected to form a "well" structure. The crisscrossed water collecting troughs 200 can cover the surface of the treatment pool and make full use of the space of the treatment pool. The use of straight water collecting troughs 200 can realize the crisscross distribution of multiple water collecting troughs 200, without the need for additional processing of the shape of the water collecting trough 200, that is, there is no need to bend or round the water collecting trough 200, which reduces the construction steps and reduces the construction difficulty and cost.
[0038] It can be understood that at least one side wall of the water collecting trough 200 is tangent to and connected to the side wall of the guide tube 100 .
[0039] The water collecting trough 200 and the guide tube 100 can be connected in a variety of ways, one of which is that the side wall of the water collecting trough 200 is tangent to and connected to the side wall of the guide tube 100. The connection method can be bolted, and the bolts pass through the side walls of the water collecting trough 200 and the guide tube 100 at the same time, and are tightened with nuts. Another connection method is to connect the water collecting trough 200 and the guide tube 100 by welding, and the welding adopts the full welding method, which is more firm than spot welding.
[0040] Reference Figure 1 As shown, it can be understood that, in a specific embodiment, the side walls of the two water collecting grooves 200 are tangent to and connected to the side walls of the guide tube 100, and the two water collecting grooves 200 connected to the guide tube 100 are parallel to each other.
[0041] The guide tube 100 is placed between two parallel water collecting grooves 200 and connected to the two water collecting grooves 200. The support of the guide tube 100 by the water collecting grooves 200 is a symmetrical structure, which has a better supporting effect on the guide tube 100 and can prevent the guide tube 100 from being tilted by the impact of water flow.
[0042] It can be understood that at least one end of the water collecting trough 200 is connected to the side wall of the guide tube 100 .
[0043] The water collection trough 200 and the guide tube 100 can be connected in a variety of ways. Another connection method is to connect the end of the water collection trough 200 to the side wall of the guide tube 100. The end of the water collection trough 200 can also be connected to the side wall of the guide tube 100 by bolts. For example, the bolts pass through the side wall of the end of the water collection trough 200 and the side wall of the guide tube 100, and are tightened with nuts. Similarly, the end of the water collection trough 200 can also be welded to the side wall of the guide tube 100, and the welding is performed in a full weld. If the end of the water collection trough 200 and the side wall of the guide tube 100 are connected by welding, there are two ways to handle the end of the water collection trough 200. The first method is to provide a side wall at the end of the water collecting trough 200, and weld the side wall at the end of the water collecting trough 200 to the side wall of the guide tube 100; the second method is not to provide a side wall at the end of the water collecting trough 200, and make an arc treatment at the end of the water collecting trough 200 so that the end of the water collecting trough 200 can fit and weld with the arc-shaped side wall of the guide tube 100, and use the side wall of the guide tube 100 as the side wall at the end of the water collecting trough 200, which can save materials.
[0044] It is understood that, in a specific embodiment, referring to Figure 2 As shown, the ends of the four water collecting grooves 200 are connected to the side walls of the guide tube 100 , and the four connection points between the water collecting grooves 200 and the guide tube 100 are evenly distributed along the circumference of the guide tube 100 .
[0045] Among the four water collecting grooves 200, the angle between two adjacent water collecting grooves 200 can be 90°, and they are evenly distributed around the guide tube 100. There are more connection points between the four water collecting grooves 200 and the guide tube 100, and the support for the guide tube 100 is more stable, and the support force distribution is balanced.
[0046] It can be understood that the water inlet of the guide tube 100 is connected to the water inlet pipe 300 , and in the vertical direction, the water inlet pipe 300 is located above the water collecting tank 200 .
[0047] The water inlet pipe 300 is located above the water collection tank 200, so that the water inlet where the water inlet pipe 300 is connected to the guide tube 100 is also located above the water collection tank 200. When the treatment tank is working, the liquid level will be maintained at the overflow surface of the water collection tank 200 and will not submerge the water collection tank 200. Therefore, the water inlet pipe 300 is located above the water collection tank 200, which can ensure that the outlet of the water inlet pipe 300 is above the liquid level of the treatment tank, that is, there is no water pressure generated by the pool water at the outlet of the water inlet pipe 300, reducing the power consumed by the sewage pump.
[0048] It can be understood that the water outlet of the guide tube 100 is located at the lower end surface of the guide tube 100 .
[0049] With the water inlet position of the guide tube 100 unchanged, the water outlet of the guide tube 100 is set on the lower end surface, and the guide tube 100 is set vertically, which can extend the flow path from the water inlet to the water outlet of the guide tube 100 as much as possible, consume the kinetic energy of sewage and suspended matter, and improve sedimentation efficiency.
[0050] It is understandable that the upper portion of the side wall of the sump 200 is provided with a serration portion.
[0051] The serrated portion forms a serrated weir on the upper portion of the side wall of the water collection tank 200 , which can further prevent solid floating objects from entering the water collection tank 200 .
[0052] Reference Figure 3 As shown, a treatment pool according to an embodiment of the utility model includes a pool body 400 of the treatment pool and the above-mentioned vertical flow sedimentation structure, wherein the water collection tank 200 is connected to the inner wall of the pool body 400 .
[0053] At least one water collection trough 200 is connected to the guide tube 100, so the water collection trough 200 can be fixed to the treatment tank without the need to add an additional support structure to fix and support the guide tube 100. The water collection trough 200 is directly used to support the guide tube 100, that is, the water collection trough 200 and the guide tube 100 are of intensive design. The water collection trough 200 and the guide tube 100 are connected, and the water collection trough 200 and the guide tube 100 can be installed at the same time, which makes the construction of the treatment tank more convenient. There are multiple water collection troughs 200, which can make full use of the internal space of the treatment tank, increase the overflow collection points of multiple supernatants, and reduce the load of a single water collection trough 200. Through the function of the guide tube 100, although the water enters from the upper part of the treatment tank, the sewage can be introduced into the lower part of the treatment tank. Water enters the upper part of the guide tube 100, and the sewage pump does not need to overcome the water pressure in the pool, consumes less electric energy, and can also introduce sewage into the lower part of the treatment pool through the guide tube 100, which will not cause sewage short-flow, ensuring a good sedimentation effect. The sewage flows from the guide tube 100 into the lower part of the treatment pool, and then overflows into the sump 200. The sewage flows downward first and then upward, and the flow direction is reversed. The kinetic energy of the suspended matter flowing with the sewage is consumed at the reverse point, and combined with the effect of gravity, the sedimentation of the suspended matter is promoted, so the sedimentation efficiency can also be improved.
[0054] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
