Abstract
Description
Technical Field
[0001] The invention relates to the field of water treatment equipment, in particular to a sewage container structure for an air flotation device. Background Art
[0002] Air flotation devices are usually used to remove proteins, hydrophobic organic matter, microorganisms and other suspended impurities in water, and are often used in sewage treatment, aquaculture, ornamental fish farming, microbial concentration collection and other fields. Existing air flotation devices are prone to bursting when the water level rises sharply, and are prone to discharge a large amount of water, causing the sewage container to overflow after it is filled; if the overflow sewage returns to the main water body, it will cause water quality to deteriorate; if the overflow does not return to the main water body, it will cause a large amount of water loss; there is room for improvement. Summary of the invention
[0003] In order to solve the above problems, the present invention provides a sewage container structure for an air flotation device.
[0004] A sewage container structure for an air flotation device has the advantages that: It comprises a first chamber (R1), a second chamber (R2), and a backflow suppression channel (F); The first chamber (R1) is located above the second chamber (R2), and the two chambers are connected via a backflow suppression channel (F); A backflow suppression channel (F) is configured such that the resistance of the liquid flowing from the first chamber (R1) to the second chamber (R2) is smaller than the resistance of the liquid flowing from the second chamber (R2) to the first chamber (R1); The first chamber (R1) has a water inlet and an overflow channel (C1); The second chamber (R2) has a sewage discharge channel (C2); The point where the overflow channel (C1) communicates with the first chamber (R1) is higher than the backflow suppression channel (F); The highest point of the drain channel (C2) is higher than the overflow channel (C1) and higher than the backflow suppression channel (F).
[0005] Further: a backflow suppression channel (F) having a one-way valve or a float valve.
[0006] Further: Backflow suppression channel (F) with Tesla valve, one-way resistance structure or curved pipe.
[0007] Further: the backflow suppression channel (F) is a vertical channel, an inclined channel, a siphon channel or a curved channel.
[0008] Furthermore: the sewage discharge channel (C2) is connected to a manual pump (NQ), and when the second chamber (R2) needs to be cleaned, the manual pump (NQ) is manually operated to discharge sewage.
[0009] Furthermore: the sewage discharge channel (C2) is a siphon tube. When the manual pump (NQ) is started, it enters the siphon mode and quickly discharges the sewage. When the sewage in the second chamber (R2) is completely 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.
[0010] Further: an alarm is added to the overflow channel (C1), and an alarm is sounded when concentrated sewage or burst water overflows through the overflow channel (C1).
[0011] Furthermore: the cross-sectional area of the sewage discharge channel (C2) is greater than the cross-sectional area of the first cavity (R1).
[0012] Furthermore: the first cavity (R1) and the second cavity (R2) are split structures, consisting of a plurality of solid cavities.
[0013] Furthermore, the first cavity (R1) and the second cavity (R2) are an integrated structure, and are formed by cavities of the same entity.
[0014] Furthermore, the backflow suppression channel (F) shares part or all of the structure with the second chamber (R2).
[0015] The principle of the present invention is as follows: during normal operation, the concentrated sewage discharged by the flotation device enters the second chamber (R2) through the first chamber (R1) and the backflow suppression channel (F) and is stored; 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 to the main water body, thereby reducing or preventing the sewage in the second chamber (R2) from entering the main water body during a burst, thereby reducing or avoiding the pollution of the main water body. Beneficial Effects
[0016] 1. Provides a new technical approach to reduce or prevent main water pollution caused by bursting.
[0017] 2. Simple structure, low cost and easy to manufacture. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiment 1, as Figure 1 As shown, a sewage container structure for an air flotation device has the advantages that: It comprises a first chamber (R1), a second chamber (R2), and a backflow suppression channel (F); The first chamber (R1) is located above the second chamber (R2), and the two chambers are connected via a backflow suppression channel (F); The backflow suppression channel (F) makes the resistance of the liquid flowing from the first chamber (R1) to the second chamber (R2) smaller than the resistance of the liquid flowing from the second chamber (R2) to the first chamber (R1), thereby reducing the backflow; The first chamber (R1) has a water inlet and an overflow channel (C1); The second chamber (R2) has a sewage discharge channel (C2) for discharging sewage to both the equipment and the main water body; The point where the overflow channel (C1) communicates with the first chamber (R1) is higher than the backflow suppression channel (F) to ensure that the liquid flows preferentially into the second chamber (R2); The point where the overflow channel (C1) communicates with the first chamber (R1) is lower than the water inlet of the first chamber (R1); The highest point of the drain channel (C2) is higher than the overflow channel (C1) and higher than the backflow suppression channel (F).
[0025] The backflow suppression channel (F) has a one-way valve, the forward opening resistance of the one-way valve is very low, and the reverse blocking can be regarded as infinite reverse resistance.
[0026] Embodiment 2, as Figure 2 As shown, the difference from Example 1 is that the backflow suppression channel (F) has a float valve, and when the second chamber (R2) is not full, the float falls, the backflow suppression channel (F) is open, and the liquid flows from the first chamber (R1) to the second chamber (R2); when the second chamber (R2) is full, the float floats up to block the backflow suppression channel (F) to prevent backflow.
[0027] Embodiment 3, as Figure 3 As shown, the difference from Example 2 is that: 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 manually operated to discharge sewage.
[0028] The sewage channel (C2) is a siphon tube. When the manual pump (NQ) is started, it enters the siphon mode and quickly discharges sewage.
[0029] Embodiment 4, as Figure 4 As shown, the difference from Example 2 is that: the backflow suppression channel (F) and the second chamber (R2) partially share the structure, the lower end of the backflow suppression channel (F) is conical, and the float can move freely at the lower end of the backflow suppression channel (F) in the second chamber (R2). When the second chamber (R2) is full, the float floats up into the cone to block the backflow suppression channel (F). When there is no liquid in the second chamber (R2), the float falls back into the second chamber (R2) under the action of gravity; the lower end of the sewage channel (C2) is provided with a blocking net to prevent the float from blocking the sewage channel (C2).
[0030] Embodiment 5, as Figure 5 As shown, the difference from Example 2 is that the backflow suppression channel (F) is a siphon channel with a siphon function; the point where the overflow channel (C1) is connected to the first chamber (R1) is higher than the highest point of the backflow suppression channel (F).
[0031] Embodiment 6 is different from Embodiment 1 in that the backflow suppression channel (F) has a Tesla valve or a one-way resistance structure or a curved pipeline.
[0032] Note: When the reader commercializes the present invention, he should note that the specific height of the connection point between the overflow channel (C1) and the first chamber (R1) and the upper end of the reflux suppression channel (F) should be determined according to the opening pressure parameter of the selected one-way valve to ensure that the one-way valve opens before the liquid level in the first chamber (R1) reaches the overflow channel (C1).
[0033] Others: Although the present invention is concise, it is cleverly designed; achieving good beneficial effects with a simple design is precisely the embodiment of the exquisite design of the present invention; readers should judge the creativity of the present invention from multiple perspectives, including 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 thinking and denying the creativity of the present invention on the grounds that the present invention is simple; it should be noted that simplicity does not mean easy to think of, and technical inspiration must be closely linked to the content disclosed by the prior art and analyzed in combination with the ability limitations of the virtual person of the technical personnel in the relevant field under the patent law.
