Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an effluent component and a regulating tank. Background Technology

[0002] Equalization tanks are crucial facilities in wastewater treatment. Their core function is to balance water volume and quality fluctuations by regulating the water flow, creating stable conditions for subsequent treatment processes, and achieving initial pollutant removal. The performance of the equalization tank directly affects the treatment efficiency and system stability of the subsequent wastewater treatment system. If the quality and quantity of the pretreated effluent from the equalization tank are unstable, it will affect the treatment efficiency of subsequent treatment units, and may even cause the effluent quality to fail to meet discharge standards.

[0003] Equalization tanks typically use fixed effluent pipes as their effluent outlet. By pre-burying the effluent pipe below the maximum effective depth at the tank's outlet end to create a fixed outlet point, the effluent flow rate can be controlled. Furthermore, a diagonal effluent distribution method is used to regulate the uniformity of water quality entering the tank from different batches. Currently, most equalization tanks pre-bury fixed effluent pipes diagonally below the effective water level to ensure the uniformity of effluent flow rate and quality. However, since the wastewater received by the pretreatment unit of the equalization tank is initial wastewater with high suspended solids and silt content—for example, pharmaceutical wastewater and brewing wastewater have high suspended solids concentrations, while municipal wastewater has high silt content—sedimentation tanks must be added upstream or downstream of the equalization tank.

[0004] However, this method increases the number of processing units and the difficulty of daily operation and management, making it unsuitable for treatment systems with limited space. Therefore, the current solution is to add a sludge settling zone and sludge collection system at the bottom of the equalization tank. However, this has the following drawbacks: because the diagonal effluent pipes are pre-buried in the settling area, the suspended solids and silt content in the effluent remains high, failing to achieve the expected settling effect. Utility Model Content

[0005] This utility model provides a water outlet component and a regulating tank to solve the technical problem that the diagonal water outlet pipe is pre-buried in the sedimentation area, resulting in a high content of suspended solids and silt in the water, which fails to achieve the expected sedimentation effect.

[0006] This utility model provides a water outlet assembly, the water outlet assembly comprising: Two identical guide vanes are fixedly connected at one edge of each other; and The water outlet pipe has its two sides fixed to the two guide plates respectively, and several water passage holes are provided on both sides of the water outlet pipe.

[0007] The principle of the water outlet component of this utility model is as follows: the wastewater to be treated flows from top to bottom under the action of gravity. Large particles such as mud, sand and suspended solids in the wastewater are blocked by the guide plate. After the water accumulates to a certain level, it enters the water outlet pipe through the water passage, thereby effectively removing large particles such as mud, sand and suspended solids in the wastewater and improving the sedimentation effect.

[0008] In one embodiment of the present invention, the water passage hole is located at the upper two sides of the water outlet pipe.

[0009] Unlike existing technologies that typically place water passages at the bottom of the outlet pipe, this invention places the water passages at the upper two sides of the outlet pipe, which increases the difficulty for large particles such as mud, sand, and suspended solids to enter the outlet pipe, thereby improving the removal effect of large particles such as mud, sand, and suspended solids in wastewater and further improving the sedimentation effect.

[0010] In one embodiment of the present invention, all the water passage holes are evenly distributed on both sides of the water outlet pipe.

[0011] In this utility model [1], by setting all the water passage holes to be evenly distributed on both sides of the water outlet pipe, the problem of flow fluctuation caused by uneven distribution of water passage holes can be avoided.

[0012] In one embodiment of the present invention, the water outlet pipe includes an inlet end and an outlet end, and the diameter of the water passage hole near the outlet end is larger than the diameter of the water passage hole near the inlet end.

[0013] In this invention, by setting the diameter of the water passage near the outlet end to be larger than that of the water passage near the inlet end, it is possible to increase the difficulty for large particulate impurities such as mud, sand, and suspended solids near the inlet end to enter the outlet pipe, thereby improving the removal effect of large particulate impurities such as mud, sand, and suspended solids in wastewater and further improving the sedimentation effect.

[0014] In one embodiment of the present invention, the water outlet assembly further includes a filter screen, the two side edges of which are respectively fixed to the two guide plates, and the filter screen is located below the water outlet pipe.

[0015] In this invention, by adding a filter screen and fixing the two sides of the filter screen to the two guide plates respectively, and by setting the filter screen below the water outlet pipe, large particles such as mud, sand, and suspended solids can be blocked from entering the water outlet pipe through the filter screen, thereby improving the removal effect of large particles such as mud, sand, and suspended solids in wastewater and further improving the sedimentation effect.

[0016] In one embodiment of this utility model, the two side edges of the filter screen are respectively fixed to the two guide plates by a fixed connecting element.

[0017] In one embodiment of this utility model, the included angle between the two guide plates is less than or equal to 90°.

[0018] In this invention, by setting the included angle between the two guide plates to be less than or equal to 90°, the inclined surface formed by the guide plates can improve the blocking effect on large particulate impurities such as mud, sand, and suspended solids, thereby improving the removal effect of large particulate impurities such as mud, sand, and suspended solids in wastewater, and further improving the sedimentation effect.

[0019] In one embodiment of this utility model, the guide plate is made of metal or polytetrafluoroethylene.

[0020] In one embodiment of this utility model, the water outlet pipe is made of metal or polytetrafluoroethylene.

[0021] This utility model also provides an equalization tank, which includes the water outlet component as described above. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In related technologies, suspended solids and silt in wastewater are treated by adding a sludge settling zone and a sludge collection system at the bottom of the equalization tank. The inventors discovered that this method has the following drawbacks: because the diagonal effluent pipes are pre-buried in the settling zone, the content of suspended solids and silt in the effluent remains high, failing to achieve the desired settling effect.

[0027] To address the aforementioned technical problems, one embodiment of this utility model provides a water outlet component, comprising: Two identical guide vanes 1 are fixedly connected at one edge, with the included angle between the two guide vanes less than or equal to 90°. The guide vanes 1 are made of metal or polytetrafluoroethylene. The water outlet pipe 2 has its two sides fixed to two guide plates 1 respectively. Several water passage holes 21 are provided on the upper two sides of the water outlet pipe 2. All water passage holes 21 are evenly distributed on the two sides of the water outlet pipe 2. The water outlet pipe includes an inlet end 22 and an outlet end 23. The diameter of the water passage hole 21 near the outlet end 23 is larger than the diameter of the water passage hole 21 near the inlet end 22. The water outlet pipe 2 is made of metal or polytetrafluoroethylene.

[0028] In another embodiment of the present invention, the water outlet assembly further includes a filter screen 3, the two side edges of the filter screen 3 are respectively fixed on two guide plates 3, and the filter screen 3 is located below the water outlet pipe 2. The two side edges of the filter screen 3 are respectively fixed on two guide plates 1 by a fixing connecting element 4.

[0029] Another embodiment of this utility model provides an regulating tank including the water outlet component as described above.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0033] Example 1 Please see Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 This is a schematic diagram of the water outlet assembly provided in this embodiment. The water outlet assembly includes two guide plates 1 of the same specification and a water outlet pipe 2.

[0034] like Figure 1 and Figure 2 As shown, the two guide plates are of the same specifications. Guide plate 1 is used to block large particles such as mud, sand, and suspended solids in the wastewater from entering the effluent pipe 2. The two guide plates 1 are fixedly connected at one edge, forming an umbrella-like structure. The two guide plates 1 can be integrally formed or fixedly connected by welding, riveting, or other methods. The included angle between the two guide plates is less than or equal to 90°, and the material of guide plate 1 is metal or polytetrafluoroethylene (PTFE). Examples of metals include stainless steel, galvanized steel, and copper.

[0035] In this embodiment, by setting the included angle between the two guide plates 1 to less than or equal to 90°, the inclined surface formed by the guide plates 1 can improve the blocking effect on large particulate impurities such as mud, sand, and suspended solids, thereby improving the removal effect of large particulate impurities such as mud, sand, and suspended solids in wastewater and improving the sedimentation effect.

[0036] Please continue reading. Figure 1 and Figure 2The outlet pipe 2 serves as a channel for wastewater flow. The two sides of the outlet pipe 2 are fixed to two guide plates 1, specifically, by welding, riveting, or other methods. The outlet pipe includes an inlet end 22 and an outlet end 23. Several water passage holes 21 are provided on both sides of the upper part of the outlet pipe 2, evenly distributed along the upper sides. The diameter of the water passage holes 21 near the outlet end 23 is larger than that near the inlet end 22. The outlet pipe 2 is made of metal or polytetrafluoroethylene (PTFE). Examples of metals include stainless steel, galvanized steel, and copper.

[0037] Unlike existing technologies where water passages are typically located at the bottom of the outlet pipe, this embodiment positions the water passages 21 at the upper edges of the outlet pipe 2. This increases the difficulty for large particles such as mud, sand, and suspended solids to enter the outlet pipe 2, thereby improving the removal of these particles from wastewater and enhancing sedimentation. Furthermore, by evenly distributing all water passages 21 along the edges of the outlet pipe 2, this embodiment avoids flow fluctuations caused by uneven distribution of the water passages.

[0038] The principle of the effluent component in this embodiment is as follows: the wastewater to be treated flows from top to bottom under the action of gravity. Large particles such as mud, sand and suspended solids in the wastewater are blocked by the guide plate 1. After the water accumulates to a certain level, it enters the effluent pipe 2 through the water passage 21, thereby effectively removing large particles such as mud, sand and suspended solids in the wastewater and improving the sedimentation effect.

[0039] Example 2 Please see Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 This is a schematic diagram of the water outlet component provided in this embodiment.

[0040] like Figure 3 and Figure 4 As shown, this embodiment differs from Embodiment 1 in that it also includes a filter screen 3. The two side edges of the filter screen 3 are respectively fixed to two guide plates 1. Specifically, the two side edges of the filter screen 3 are fixed to the two guide plates 1 respectively by fixing connecting elements 4, and the filter screen 3 is located below the water outlet pipe 2. The filter screen 3 is made of metal or polytetrafluoroethylene. Examples of metals include stainless steel, galvanized steel, and copper. Examples of fixing connecting elements 4 include bolts and rivets.

[0041] In this embodiment, by adding a filter screen 3 and fixing the two sides of the filter screen 3 to the two guide plates 1 respectively, and setting the filter screen 3 to be located below the water outlet pipe 2, the filter screen 3 can block large particulate impurities such as mud, sand and suspended solids from entering the water outlet pipe 2, thereby improving the removal effect of large particulate impurities such as mud, sand and suspended solids in wastewater, and further improving the sedimentation effect.

[0042] Not limited thereto, the present invention also provides an equalization tank, which includes the water outlet component as described above.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
