Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This utility model claims priority to Chinese Patent Application No. 202410474785.X, entitled “Water outlet device for enameled assembled tank biochemical reactor,” filed on April 19, 2024. The entire contents of the aforementioned application are incorporated herein by reference. Technical Field

[0003] The utility model relates to the technical field of sewage treatment, in particular to a water outlet device for an enamel assembled tank type biochemical reactor. Background Art

[0004] In the field of sewage treatment, with the expansion of urban scale and the improvement of people's living standards, the amount of urban sewage has increased dramatically. A large number of urban sewage treatment plants across the country are experiencing sewage overflow or seasonal sewage overflow problems, and the demand for emergency sewage treatment facilities has increased dramatically. Compared with conventional reinforced concrete tanks and carbon steel welded tanks, prefabricated sewage treatment plants have the advantages of low investment, simple construction, short construction period, and less climatic constraints, which can save capital and time costs. In this environment, enameled assembled tank technology has gradually entered the field of vision of environmental protection professionals.

[0005] Enamel assembled tanks use special high-strength enameled steel as the base material. Professional enameling technology is used to combine a highly inert anti-corrosion glaze layer with the surface of the base material to form a standardized steel plate module. After the module is transported to the project site, it is assembled quickly and with low consumption to complete the tank body forming process.

[0006] In the existing technology, the water outlet method of the enameled tank biochemical reactor is usually to directly install the water outlet pipe on the side wall. However, with the sharp increase in the amount of overflow sewage and the tight land occupation of new water plants, the treatment scale of enameled assembled tank sewage treatment plants is constantly expanding, and the concentration of total nitrogen pollution indicators in sewage water quality is also constantly rising, and the volume of enameled assembled tank sewage treatment equipment is constantly increasing.

[0007] Generally speaking, for larger treatment projects, the outlet pipe diameter is between 800mm and 12000mm. In this way, the liquid level will fluctuate with the fluctuation of the inlet flow. When the water volume is small, the liquid level may be in the lower half of the outlet pipe. When the water volume is large, the liquid level is at the highest point of the pipe. When the water volume is small, the volume of the height difference is wasted, which often causes the liquid level in the enameled tank biochemical reactor to fluctuate with the fluctuation of the inlet water volume, and the actual treatment residence time does not meet the design requirements. In addition, due to the special cylindrical structure of the enameled tank bioreactor, the single-point water inlet and single-point water outlet will cause a large number of hydraulic dead corners in the reaction, making it impossible to fully utilize the tank volume, resulting in a significant reduction in the treatment effect and failure to meet the process design requirements.

[0008] In addition, the size of the enamel assembled tank is usually large, and the corresponding separate water outlet device is not easy to process and transport. Utility Model Content

[0041] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0043] The following combination Figures 1 to 6 The utility model describes a water outlet device for an enamel assembled tank type biochemical reactor.

[0044] like Figure 1 As shown, an embodiment of the present invention provides a water outlet device for an enameled assembled tank biochemical reactor. The device comprises multiple water outlet structures, with adjacent water outlet structures detachably connected. Each water outlet structure comprises a base plate 1 and a pair of side plates 2. The base plate 1 is positioned along the inner wall of the enameled assembled tank biochemical reactor near the top. The base plate 1 primarily serves as the foundation of the water outlet device, carrying and guiding liquid toward the outlet. The shape and dimensions of the base plate 1 may need to be designed based on the specific shape and size of the reactor to ensure effective collection and drainage of liquid. A pair of side plates 2 are positioned perpendicularly on either side of the base plate 1, forming a U-shaped structure with an open top. One of the water outlet structures has a water outlet 3 at its bottom. This design allows liquid to enter the water outlet device through the top opening of the U-shaped structure and flow toward the outlet 3 under the guidance of the base plate 1. The height and thickness of the side plates are also determined based on actual needs to ensure the stability and durability of the water outlet device. The outlet 3 serves to drain liquid from the water outlet device. The design and location of the water outlet 3 need to take into account the flow rate and flow rate of the liquid to ensure that the liquid can be discharged smoothly without causing blockage or leakage.

[0045] The water outlet device provided by the utility model for the enameled assembled tank type biochemical reactor provides a linear water collection method, which is arranged along the inner wall of the enameled assembled tank type biochemical reactor near the top. When the liquid level in the enameled assembled tank type biochemical reactor reaches the height of the side plate 2, the liquid will flow into the water outlet structure and be discharged through the water outlet 3, thereby achieving liquid level stability, so that the actual treatment residence time of the liquid can meet the design requirements, solving the problem of insufficient treatment effect caused by unstable liquid level and inability to fully utilize the tank volume, and ensuring the operational stability of the water outlet device.

[0046] In a feasible embodiment of the present invention, the water outlet device may be an annular structure. When it is annular, the side plates are arranged along the inner wall of the enamel assembled tank type biochemical reactor to form a closed loop.

[0047] The water outlet device can also be an arc-shaped structure, and both ends of the arc-shaped water outlet device are blocked. The arc length of the arc-shaped water outlet device can be set according to actual needs. Specifically, both ends of the arc-shaped water outlet device can be blocked by steel plates.

[0048] It should be noted that the side panels can be fixedly connected to the inner wall of the enameled assembled tank biochemical reactor. The annular or curved design can provide more uniform and stable support, helping to enhance the overall stability of the water outlet structure and reduce deformation caused by liquid flow or external pressure. The annular or curved water outlet structure can better guide liquid flow, reduce the formation of dead angles and vortices, and improve water outlet efficiency.

[0049] In another embodiment, the multiple water outlet structures can also be surrounded by a regular polygon, and there is a gap between each water outlet structure and the inner wall of the enameled assembled tank biochemical reactor, which can allow a larger error than the circular ring structure and is convenient for processing and installation.

[0050] like Figure 2 、 Figure 3 and Figure 4 As shown, in a feasible embodiment of the present invention, a pair of adjustable water outlet weirs 4 are further included, which are detachably connected to the side panels 2 respectively, and the liquid level of the water outlet device is adjusted by the height of the adjustable water outlet weir 4. The main function of the adjustable water outlet weir 4 is to allow the user to adjust the water outlet flow rate of the water outlet device according to needs. By changing the height or position of the water outlet weir, the rate and amount of water flow can be controlled to meet different process requirements. In an enameled assembled tank biochemical reactor, uniform water flow distribution is crucial to the stability and efficiency of the reaction process. The adjustable water outlet weir 4 can help achieve a more uniform water flow distribution and reduce the phenomenon of local water flow being too large or too small.

[0051] See again Figure 1As shown, in a feasible embodiment of the present invention, the adjustable water outlet weir 4 and the side plate 2 are both provided with a first elongated bolt hole and a second elongated bolt hole, wherein the first elongated bolt hole and the second elongated bolt hole extend perpendicularly to each other, allowing the adjustable water outlet weir 4 to have a certain range of movement in both the horizontal and vertical directions. This means that the position of the adjustable water outlet weir 4 can be fine-tuned as needed to achieve the optimal water outlet effect. The design of the elongated bolt holes makes the installation and adjustment process relatively simple. The staff only needs to pass the bolts through the corresponding bolt holes and then fix them in the appropriate position. This design reduces the difficulty and time of installation and adjustment. The adjustable water outlet weir 4 can be a triangular weir, a submerged rectangular weir, or a non-submerged rectangular weir. By adjusting the position of the adjustable water outlet weir 4 in the elongated bolt holes, it can be adapted to side plates 2 of different sizes, making the adjustable water outlet weir 4 suitable for various reactors.

[0052] See again Figure 1 As shown, adjacent water outlet structures can be connected by customized flanges 10 and quick-assembly fasteners. When the water outlet device is annular, each water outlet structure is connected end to end by customized flanges and quick-assembly fasteners to form a complete water outlet device. When the water outlet device is an arc-shaped structure, the ends of the water outlet structures installed at the head and tail are sealed with steel plates, and the customized flanges are eliminated at the ends. From a construction perspective, the external dimensions of each part are controlled during the equipment production stage, and special connecting components such as customized flanges 10 are designed. On-site, they can be quickly connected into a complete device by bolts, which not only reduces on-site welding work, saves a lot of construction time, avoids the hoisting construction of large equipment, reduces construction difficulty, but also avoids damage to the anti-corrosion layer caused by welding.

[0053] like Figure 3 As shown, the customized flange 10 can be made of two angle steels, one side of the angle steel is firmly welded along the edge of the side panel 2, and the other end is perpendicular to the side panel 2. Several bolt holes are drilled on the angle steel surface perpendicular to the side panel 2, and fasteners are quickly assembled through the bolt holes to form a stable connection.

[0054] like Figure 4As shown, in a feasible embodiment of the present invention, a reinforcing structure 5 is further included, which is arranged on the inner wall of the water outlet structure, or can be arranged on the outer wall of the water outlet structure. Regardless of whether it is arranged on the inner wall or the outer wall of the water outlet structure, the reinforcing structure can provide additional support and reinforcement for the water outlet structure, enhancing its ability to withstand external pressure and internal water flow impact, thereby improving the stability of the entire water outlet structure. When used for a long time or subjected to large external forces, the water outlet structure may experience problems such as deformation or cracking. The provision of the reinforcing structure 5 can effectively prevent the occurrence of these problems and extend the service life of the water outlet structure. The reinforcing structure 5 can optimize the stress distribution inside the water outlet structure and reduce the risk of damage caused by stress concentration. This helps to ensure that the water outlet structure can maintain stable performance under various working conditions. The outer wall reinforcement structure is mainly reinforced against external pressure and impact. It can enhance the overall rigidity and stability of the water outlet structure and prevent deformation and damage caused by external factors.

[0055] See again Figure 1 As shown, in a feasible embodiment of the present invention, the reinforcing structure 5 includes an in-channel tie bar 6 and a reinforcing rib 7. The two ends of the in-channel tie bar 6 are respectively connected to the side panel 2 to form a transverse support structure. This structural design can effectively prevent the side panel 2 from being deformed or displaced due to external pressure or internal water flow impact, thereby enhancing the stability of the side panel 2. The presence of the in-channel tie bar 6 changes the stress distribution inside the water outlet structure, so that the stress can be more evenly distributed throughout the structure. This helps to reduce the risk of damage caused by stress concentration and improves the overall strength of the water outlet structure. There can be multiple in-channel tie bars 6, and multiple in-channel tie bars 6 are arranged along the extension direction of the water outlet device and can be arranged alternately up and down, which can ensure that the water outlet device has sufficient support and stability in the length direction. It is suitable for longer water outlet devices and can effectively prevent structural instability caused by excessive length.

[0056] The reinforcing ribs 7 are provided on the bottom and / or side walls of the bottom plate 1 to provide additional support and reinforcement for the bottom plate 1. This helps prevent the bottom plate 1 from bending or cracking when subjected to water flow impact or gravity load, thereby improving the robustness of the bottom plate 1. After prolonged use or under high flow conditions, the bottom plate 1 may deform due to fatigue. The provision of the reinforcing ribs 7 can effectively prevent such deformation from occurring, maintaining the patency and stability of the water outlet device. The reinforcing ribs 7 not only enhance the robustness of the bottom plate 1, but also enhance the rigidity of the entire water outlet structure. This enables the water outlet structure to maintain better shape stability and reduce vibration and noise when subjected to external disturbances. The reinforcing ribs 7 may include vertical reinforcing ribs and horizontal reinforcing ribs. The height of the vertical reinforcing ribs shall not be less than two-thirds of the height of the side plate 2. The horizontal reinforcing ribs are provided at the bottom of the bottom plate 1 to ensure that the water outlet structure does not deform after water enters.

[0057] In a feasible embodiment of the present invention, a plurality of anti-floating holes 8 are provided on the bottom plate 1. In an enameled assembled tank-type biochemical reactor, when the water outlet device is filled with liquid, the bottom plate will be subjected to an upward buoyancy. If the buoyancy is greater than the deadweight of the bottom plate 1 and the structural support force, the bottom plate may float up, resulting in structural instability. The provision of the anti-floating holes 8 can effectively balance this buoyancy and reduce the risk of floating. By providing the anti-floating holes 8, the contact area between the bottom plate 1 and the liquid is reduced, thereby reducing the overall effect of the buoyancy on the bottom plate 1.

[0058] Distributing the anti-float holes 8 along the bottom plate's midline ensures a more even distribution of buoyancy across the bottom plate 1. This prevents excessive buoyancy in certain areas due to concentrated buoyancy, improving the stability of the entire bottom plate 1. The midline is typically the axis of symmetry for the bottom plate 1, and placing the anti-float holes 8 there better maintains the symmetry and aesthetics of the bottom plate 1. This layout also helps optimize the overall structural performance of the water outlet device.

[0059] In a feasible embodiment of the present invention, it also includes a plurality of support devices 9, which are arranged at the bottom of the base plate 1. The support devices 9 are directly installed at the bottom of the base plate 1 to provide additional support force for the base plate. This helps to disperse the weight and load borne by the base plate 1 and prevent deformation or sinking due to gravity or external pressure. By installing multiple support devices 9, the overall stability of the water outlet device is enhanced. These support devices 9 can jointly withstand forces and moments from different directions to maintain the shape and structural stability of the water outlet device. In an environment filled with liquid, the base plate 1 may be subjected to an upward buoyancy. The presence of the support devices 9 can effectively counteract this buoyancy and prevent the base plate 1 from floating up, thereby maintaining the normal use of the water outlet device.

[0060] In one possible embodiment of the present invention, the support device 9 comprises a triangular support assembly. The triangle has inherent stability, a common stable shape in architectural and structural design. The triangular support assembly leverages this characteristic to provide strong support for the base plate, effectively preventing deformation or sinking of the base plate 1. The triangular support assembly's structural design disperses the load from the base plate, evenly distributing it across the support points, thereby reducing stress on individual support points and improving the durability of the overall structure.

[0061] The support device 9 can also be a vertical support assembly. This assembly primarily bears vertical loads, providing strong support for the baseplate. The vertical support assembly is relatively compact, taking up little space and is suitable for installations with limited space. A steel plate is welded to the top of the assembly, which is welded to the water outlet. Reinforcement ribs are welded to the bottom of the assembly.

[0062] In summary, the water outlet device for the enameled assembled tank biochemical reactor provided by the utility model is installed along the side wall of the enameled assembled tank biochemical reactor. From a process perspective, the liquid level of the reactor can be adjusted so that the liquid level does not change due to the amount of water, thereby ensuring the uniformity of the water outlet and sufficient process time. From a construction perspective, rapid assembly and molding are adopted, which not only reduces on-site welding work and saves a lot of construction time, but also avoids damage to the anti-corrosion layer caused by welding. In addition, the utility model adopts multi-part assembly, which can control the external dimensions through the production stage, avoids the lifting and construction of large equipment, and reduces the difficulty of construction.
