Description

Technical Field

[0001] This utility model relates to wastewater treatment equipment, and more particularly to a wastewater reuse equipment. Background Technology

[0002] In the field of wastewater reuse, physical filtration is a crucial pretreatment step. Traditional wastewater filtration equipment often uses single-point or simple pipeline water distribution methods, resulting in severely uneven distribution of wastewater on the filter media surface. This easily leads to "channeling" (concentrated water flow scouring localized areas) and "short-circuiting" (insufficient water flow in some areas), causing rapid clogging of local filter media and low overall utilization, significantly reducing filtration efficiency. Furthermore, clogged filter media often requires complete replacement, resulting in high maintenance costs and cumbersome operation. In addition, traditional systems often rely on a single inlet pipe and a single pump, posing a significant risk of single-point failure. If the pump fails, the entire system collapses. Moreover, their capacity is limited when handling large volumes of wastewater, resulting in insufficient system reliability and processing capacity. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a wastewater reuse device.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is: a wastewater reuse device, including a vertical frame, a lower section for installing multiple sets of water collection tanks and an upper section for installing filter boxes.

[0005] A water system assembly is installed outside the vertical frame. The water system assembly includes a pre-stage pipe with one inlet and two outlets, and a post-stage pipe with two inlets and two outlets connected to the pre-stage pipe. A water pump is installed at each of the two connection points of the pre-stage pipe and the post-stage pipe.

[0006] The two output ends of the downstream pipeline are connected one-to-one to the diffuser plates located in the filter box for dispersing water flow; the two diffuser plates are distributed at different heights, and filter elements are laid under each diffuser plate;

[0007] The lower part of the filter box is connected to the water collection tank through a delivery pipeline.

[0008] Furthermore, the one-input, two-output pre-stage pipeline includes a first main line at the input end and two first branch lines at the output end; the two-input, two-output post-stage pipeline includes two second front branch lines at the input end, a second main line at the intermediate end, and two second post branch lines at the output end.

[0009] Furthermore, both first branches are connected to the second front branch via a water pump.

[0010] Furthermore, valves are installed on the first main road, the first branch road, and the second main road.

[0011] Furthermore, the diffuser includes a main diffuser pipe that connects laterally to the second rear branch, and several diffuser branch pipes that connect to the main diffuser pipe. The several diffuser branch pipes form a parallel, spaced toothed diffuser surface above a filter element, and each diffuser branch pipe is provided with an outlet at uniform intervals.

[0012] Furthermore, the inner diameters of several diffusion branch pipes are the same and smaller than the inner diameter of the diffusion main pipe.

[0013] Furthermore, the filter plate includes a support plate with matrix-shaped perforations, with a filter plate embedded in each perforation.

[0014] This utility model discloses a wastewater reuse device. Its clear vertical frame and modular filter plate design facilitate installation, maintenance, and replacement. The dual-pump, dual-pipeline design improves system reliability. The diffuser plate, especially the toothed branch pipes combined with the uniform outlet, and the design of a thick main pipe and thin branch pipes, are key to ensuring filtration efficiency, ensuring that wastewater evenly covers the entire filter surface and preventing channeling or dead zones.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] In this embodiment, Figure 1 and 4The wastewater reuse equipment shown includes a vertical frame 500, comprising a lower section with multiple sets of water collection tanks 600 installed within the vertical frame 500, and an upper section with filter boxes 700 installed. The vertical frame 500 is a frame structure welded from several horizontal beams, longitudinal beams, and vertical columns. The vertical columns provide support for the main frame structure. The entire frame structure defines the upper and lower sections. The lower section houses the water collection tanks 600, which are used to collect the finally treated reused water. In this embodiment, multiple separately assembled water collection tanks of uniform shape and size are used to facilitate future maintenance and improve operational mobility. The upper section houses the filter boxes, which are the areas where wastewater undergoes physical filtration. Therefore, the vertical frame 500 provides rigid support for the entire equipment, clearly delineates functional areas, and accommodates the core components.

[0022] In this embodiment, a water system assembly is installed outside the vertical frame 500, employing a combination of a "one inlet, two outlet" pre-stage pipeline and a "two inlet, two outlet" post-stage pipeline, in conjunction with a water pump, to achieve flow diversion, pressurization, and delivery. Specifically, as follows... Figure 2 As shown, the water system assembly includes a pre-stage pipe 100 with one inlet and two outlets, and a post-stage pipe 200 with two inlets and two outlets connected to the pre-stage pipe. A water pump 300 is installed at each connection point of the pre-stage and post-stage pipes. The pre-stage pipe 100 includes a first main pipe 101 at the input end and two first branch pipes 102 at the output ends. The first main pipe 101 is the inlet pipe for untreated wastewater, typically connected to the wastewater source. It can extend to a tank containing wastewater or be connected to a container containing wastewater via a flexible hose. The two first branch pipes 102 divide the inlet water into two sections. Both the main pipeline 101 and the first branch pipeline 102 are equipped with valves 400, which are used to control the total water inlet, close a single pipeline, or regulate the flow rate of a single pipeline. The water pump 300 is connected between the first branch pipeline 102 of the pre-stage pipeline 100 and the second pre-branch pipeline 201 of the post-stage pipeline 200. Therefore, there are two water pumps in this patent, which provide the power and necessary pressure for transporting wastewater, overcome pipeline resistance, and lift / pressurize the water to the diffuser plate of the filter box. The dual-pump design can be used for redundancy (if one water pump fails, the other water pump continues to work), to handle large flow rates, or to control the two pipelines separately.

[0023] In this embodiment, the two-inlet, two-outlet downstream pipeline 200 includes two second front branches 201 at the input end, one second main pipeline 202 at the middle end, and two second downstream branches 203 at the output end. The two second front branches 201 receive pressurized wastewater from two water pumps respectively. The second main pipeline 202 temporarily combines the water from the two second front branches. The two second downstream branches 203 divide the combined water into two streams for output. A valve 400 is provided on the second main pipeline 202 to control the total flow rate after combining or to shut off the entire downstream pipeline.

[0024] In this embodiment, the two output ends of the downstream pipeline are connected one-to-one to the diffuser plate 800 located inside the filter box 700 for dispersing water flow; such as Figure 3 As shown, the diffuser plate 800 includes a main diffuser pipe 801 that connects laterally to the second downstream branch, and several diffuser branch pipes 802 connected to the main diffuser pipe 801. The several diffuser branch pipes 802 form a parallel, toothed diffuser surface above a filter element 900. Each diffuser branch pipe 802 has an outlet 803 at uniform intervals. The two diffuser plates are arranged at different heights, with the filter element 900 laid beneath each diffuser plate. A filter box 700 is installed inside the filter box 700, with one high-level and one low-level filter box. This high-low arrangement is designed to create different filtration paths while increasing treatment capacity. The main diffuser pipe 801 connects to the second downstream branch pipe 203 from the downstream pipe 200. This is the main pipe entering the filter box. Diffuser branch pipes 802 are connected to the main diffuser pipe 801 in a parallel, spaced-out manner, forming a toothed diffuser surface, similar to a comb placed flat above the filter media. Each diffuser branch pipe 802 has evenly spaced perforations, which are the outlets from which wastewater finally leaves the piping system and is distributed onto the filter media. Note that the inner diameter of the diffuser branch pipes 802 is the same, but smaller than that of the main diffuser pipe 801. This helps maintain a high flow rate and reduce sedimentation within the main pipe, while achieving uniform water distribution within the branch pipes through small diameter openings and multiple outlets. The core function is to evenly and disperse the pressurized wastewater across the entire surface of the filter element 900 below. Uniform water distribution is crucial for ensuring filtration efficiency and preventing localized clogging or short circuits.

[0025] In other embodiments, the outlet can be an atomizing nozzle, a design suitable for wastewater containing no solid impurities.

[0026] In this embodiment, as Figure 3 As shown, the filter plate includes a support plate 901 with a matrix of perforated positions, with a filter plate 902 embedded in each perforation. It is laid below the diffuser plate 800 and directly receives the wastewater sprayed from the diffuser plate. Its structure includes a support plate 901 with a matrix of perforated positions (holes) and multiple independent filter plates 902, serving as independent filtration units. Each filter plate is precisely embedded in one of the perforated positions of the support plate 901. This is the core component for the physical filtration of wastewater. When wastewater passes through the filter plates 902, suspended solids and particulate matter are trapped, while relatively clean water passes through.

[0027] In other embodiments, such a design can use filter plates of different materials or precision (such as coarse filters and fine filters) combined in the same layer to achieve cascade filtration, while facilitating the replacement of clogged or damaged filter plates individually without replacing the entire large filter layer, resulting in low maintenance costs.

[0028] In this embodiment, the lower part of the filter box 700 is connected to the water collection tank 600 via a conveying pipe 1000. The filter box 700 is located in the lower section of the vertical frame. Directly below the filter box 700, the conveying pipe 1000 can be one or more pipes. Relatively clean reclaimed water filtered by the filter element 900 is collected. Gravity causes the filtered water to flow naturally into the water collection tank below for storage. The conveying pipe 1000 ensures smooth water flow into the water collection tank.

[0029] The entire system's workflow is as follows: Untreated wastewater enters the pre-pipeline through the first main channel; at the first branch channel, the wastewater is split into two streams, which are then pressurized by two separate pumps; the pressurized streams then enter the post-pipeline through the second pre-branch channel, briefly merge at the second main channel, and then split again through the second post-branch channel. The two streams then enter the high-level and low-level diffuser plates, respectively. The water first enters the main diffuser channel and then distributes to multiple diffuser branch channels; finally, it is evenly distributed through uniformly distributed outlets, spraying onto the entire surface of the filter element below, like rain. Under gravity, the wastewater permeates from top to bottom through the filter element; as it passes through the filter plates, contaminants are trapped; clean water passes through the perforations in the support plates; the filtered clean water collects at the bottom of the filter box and flows by gravity into the collection tank located in the lower zone for storage, awaiting reuse. Throughout the process, valves control the on / off state and flow rate of each water section. It should be understood that both electric and manual valves can be used.

[0030] In summary, this wastewater reuse system is a well-designed physical filtration system. It utilizes a robust frame support and employs a two-stage pipeline and dual pumps to achieve wastewater diversion, pressurization, and reliable delivery. The core innovations lie in the toothed, uniform water distribution structure of the diffuser plate and the modular matrix design of the filter elements, ensuring even distribution of wastewater across the filter media, high filtration efficiency, and convenient maintenance. Finally, the treated water is collected by gravity in the lower collection tank, completing the transformation from wastewater to reused water. The entire solution embodies the design principles of modularity, reliability, and efficient water distribution.
