Description

Technical Field

[0001] This invention relates to the field of water treatment equipment, and in particular to a wastewater container structure for an air flotation device. Background Technology

[0002] Air flotation devices are commonly used to remove proteins, hydrophobic organic matter, microorganisms, and other suspended impurities from water. They are frequently used in wastewater treatment, aquaculture, ornamental fish farming, and microbial concentration and collection. However, existing air flotation devices are prone to bursting when the water level rises rapidly, resulting in the discharge of large amounts of water and overflowing the wastewater container. If the overflowed wastewater returns to the main water body, it will lead to water quality deterioration; if the overflow does not return to the main water body, it will result in significant water loss. There is room for improvement. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a wastewater container structure for an air flotation device.

[0004] A wastewater container structure for an air flotation device has the following advantages:

[0005] Includes a first cavity (R1), a second cavity (R2), and a reflux suppression channel (F);

[0006] The first cavity (R1) is located above the second cavity (R2), and the two are connected by a backflow suppression channel (F);

[0007] The backflow suppression channel (F) makes the resistance of liquid flowing from the first cavity (R1) to the second cavity (R2) less than the resistance of liquid flowing from the second cavity (R2) to the first cavity (R1);

[0008] The first cavity (R1) has an inlet and an overflow channel (C1);

[0009] The second cavity (R2) has a sewage discharge channel (C2);

[0010] The point where the overflow channel (C1) connects to the first cavity (R1) is higher than the backflow suppression channel (F);

[0011] The highest point of the sewage discharge channel (C2) is higher than that of the overflow channel (C1) and also higher than that of the backflow suppression channel (F).

[0012] Furthermore: the backflow suppression channel (F) has a check valve or a float valve.

[0013] Further: backflow suppression channel (F) with a Tesla valve, a one-way resistance structure, or a curved pipe.

[0014] Furthermore: the backflow suppression channel (F) can be a vertical channel, an oblique channel, a siphon channel, or a curved channel.

[0015] Furthermore: The sewage discharge channel (C2) is connected to a manual pump (NQ). When the second chamber (R2) needs to be cleaned, the manual pump (NQ) is operated manually to discharge the sewage.

[0016] Furthermore: the sewage discharge channel (C2) is a siphon pipe. When the manual pump (NQ) is started, it enters the siphon mode and quickly discharges sewage. When the sewage in the second chamber (R2) is discharged, the atmosphere enters the sewage discharge channel (C2) through the first chamber (R1), the backflow suppression channel (F), and the second chamber (R2) to interrupt the siphon.

[0017] Furthermore: An alarm is added to the overflow channel (C1) to sound an alarm when concentrated wastewater or gushing water overflows through the overflow channel (C1).

[0018] Furthermore, the cross-sectional area of ​​the sewage channel (C2) is larger than the cross-sectional area of ​​the first cavity (R1).

[0019] Furthermore, the first cavity (R1) and the second cavity (R2) are separate structures, consisting of multiple solid cavities.

[0020] Furthermore, the first cavity (R1) and the second cavity (R2) are an integral structure, consisting of cavities of the same solid body.

[0021] Furthermore: the reflux suppression channel (F) shares part or all of the structure with the second cavity (R2).

[0022] The principle of this invention is as follows: During normal operation, the concentrated wastewater discharged from the flotation device enters the second chamber (R2) through the first chamber (R1) and the backflow suppression channel (F) and is stored there. When a burst occurs, the burst water first fills the second chamber (R2) and then overflows from the overflow port C1 of the first chamber (R1) back into the main water body. This can reduce or prevent the wastewater in the second chamber (R2) from entering the main water body during a burst, thereby reducing or avoiding pollution of the main water body. Beneficial effects

[0023] 1. It provides a new technical approach to reduce or prevent pollution of the main water body caused by gushing.

[0024] 2. It has a simple structure, low cost, and is easy to manufacture. Attached Figure Description

[0031] Example 1, such as Figure 1 As shown, a wastewater container structure for an air flotation device has the following advantages:

[0032] Includes a first cavity (R1), a second cavity (R2), and a reflux suppression channel (F);

[0033] The first cavity (R1) is located above the second cavity (R2), and the two are connected by a backflow suppression channel (F);

[0034] The backflow suppression channel (F) makes the resistance of liquid flowing from the first cavity (R1) to the second cavity (R2) less than the resistance of liquid flowing from the second cavity (R2) to the first cavity (R1), thus reducing backflow;

[0035] The first cavity (R1) has an inlet and an overflow channel (C1);

[0036] The second chamber (R2) has a sewage discharge channel (C2) for discharging sewage outside both the equipment and the main water body;

[0037] The overflow channel (C1) is higher than the backflow suppression channel (F) at the point where it connects with the first cavity (R1) to ensure that liquid preferentially flows into the second cavity (R2).

[0038] The overflow channel (C1) is connected to the first cavity (R1) at a point lower than the inlet of the first cavity (R1);

[0039] The highest point of the sewage discharge channel (C2) is higher than that of the overflow channel (C1) and also higher than that of the backflow suppression channel (F).

[0040] The backflow suppression channel (F) has a check valve with very low forward opening resistance and infinite reverse blockage resistance.

[0041] Example 2, as follows Figure 2As shown, unlike Example 1, the backflow suppression channel (F) has a float valve. When the second cavity (R2) is not full, the round float falls and the backflow suppression channel (F) opens, allowing liquid to flow from the first cavity (R1) to the second cavity (R2). When the second cavity (R2) is full, the round float rises and blocks the backflow suppression channel (F) to prevent backflow.

[0042] Example 3, such as Figure 3 As shown, the difference from Example 2 is:

[0043] The sewage discharge channel (C2) is connected to a manual pump (NQ). When the second chamber (R2) needs to be cleaned, the manual pump (NQ) is operated manually to discharge sewage.

[0044] The sewage discharge channel (C2) is a siphon pipe. When the manual pump (NQ) is started, it enters the siphon mode and quickly discharges sewage.

[0045] Example 4, such as Figure 4 As shown, unlike Example 2, the backflow suppression channel (F) and the second cavity (R2) share a common structure. The lower end of the backflow suppression channel (F) is conical, and the circular float can move freely at the lower end of the backflow suppression channel (F) in the second cavity (R2). When the second cavity (R2) is full, the float rises and enters the conical shape, blocking the backflow suppression channel (F). When there is no liquid in the second cavity (R2), the float falls back into the second cavity (R2) under the action of gravity. The lower end of the sewage discharge channel (C2) has a barrier net to prevent the float from blocking the sewage discharge channel (C2).

[0046] Example 5, as Figure 5 As shown, unlike Example 2, the backflow suppression channel (F) is a siphon channel with a siphon function; the overflow channel (C1) is connected to the first cavity (R1) at a point higher than the highest point of the backflow suppression channel (F).

[0047] Example 6 differs from Example 1 in that the backflow suppression channel (F) has a Tesla valve or a one-way resistance structure or a curved pipe.

[0048] Note: When commercializing this invention, readers should be aware that the specific height of the connection between the overflow channel (C1) and the first cavity (R1) and the upper end of the backflow suppression channel (F) should be determined according to the opening pressure parameters of the selected check valve to ensure that the check valve opens before the liquid level in the first cavity (R1) reaches the overflow channel (C1).

[0049] Other points: Although this invention is simple, its design is ingenious; achieving good and beneficial effects with a simple design is precisely the embodiment of the ingenuity of this invention. Readers should judge the inventiveness of this invention from multiple perspectives, such as whether the technical problem has been raised, whether the technical solution has appeared, and whether the technical effect has been produced, rather than relying on hindsight to deny the inventiveness of this invention on the grounds that it is simple. It should be noted that simplicity does not mean easy to think of. The technical inspiration must closely follow the content of the prior art and be analyzed in conjunction with the limitations of patent law on the ability of a person skilled in the art.
