Detailed Implementation

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 4 As shown, a water treatment sedimentation device is disclosed, including a tank 1, with a fiberglass movable cover 2 on the top of the tank 1 to prevent direct sunlight from causing algae growth.

[0030] The tank 1 includes a water collection tank, an inclined pipe area, a flushing area, a sludge return area, a return area, and a water inlet area.

[0031] Water collection tank: Water collection tanks are fixedly installed on the inner walls of both sides of the tank body 1, and the water outlet of the water collection tank is set through the tank body 1. The water collection tank includes a water tank body 12, and the water tank body 12 is fixedly connected to the tank body 1. A second regulating weir plate 16 is fixedly connected to both sides of the water tank body 12. A water outlet pipe 15 is fixedly passed through one side of the bottom of the water tank body 12, and the water outlet pipe 15 is set through the tank body 1 and fixedly connected to it.

[0032] The water collection tank is used to collect sedimented water. The second regulating weir plate 16 on both sides is a sawtooth-shaped outlet weir plate, which facilitates the adjustment of the outlet water level. The weir plate is 3mm thick and made of stainless steel SUS304. The weir plate is vertically adjustable with an adjustment range of not less than 30mm.

[0033] Inclined tube area: Support frame 4 is fixedly connected to both inner walls of the box 1. Inclined tube packing 3 is placed on the top of each support frame 4 and the inclined tube packing 3 is fixed to the inner wall of the box 1.

[0034] The inclined tube section uses inclined tube packing 3 for sludge-water separation. The inclined tube material is ethylene-propylene copolymer, using hexagonal honeycomb inclined tubes with an inscribed circle diameter of 80mm and a plate thickness of 0.8mm. The inclined tube is 1m long and installed at a 60° angle. The support frame 4, located below the inclined tube, is a rigid support welded from SUS304 stainless steel. The support frame 4 maintains a certain rigidity even under the most unfavorable load conditions, i.e., the weight of the inclined tube itself and the weight of the accumulated sludge, with a deflection control value of 1 / 500 of the beam span. After the inclined tube is assembled in place, it is secured at the top with nylon ropes to prevent the packing from floating.

[0035] The water outlet trough is designed as a detachable structure, which facilitates the installation and maintenance of the inclined tube packing 3.

[0036] Flushing area: The inside of the box 1 is equipped with a packing backwash pipe fitting, which includes a first main pipe 11 and two horizontal pipes 8. The first main pipe 11 is fixedly connected to the box 1 and the first main pipe 11 is fixedly connected to the adjacent horizontal pipe 8. Four first perforated pipes 5 are fixedly connected between the two horizontal pipes 8 and are fixedly connected to the box 1 and set below the inclined tube packing 3.

[0037] During the operation of the settler, a small amount of sludge will remain in the inclined tube area. In order to maintain the functional effect of the inclined tubes during long-term operation, it is necessary to backwash the inclined tube packing 3 regularly. Therefore, an inclined plate flushing system is set up. This system can backwash the inclined tube packing 3 regularly during the normal operation of the settler system without stopping the tank. This reduces the manpower consumption caused by flushing the inclined tubes and the reduction in treatment capacity caused by stopping the tank for flushing.

[0038] The flushing system consists of a first main pipe 11, two horizontal pipes 8, a first perforated pipe 5, and a control valve installed on the first main pipe 11. The pipe material is grade UPVC, the pipe diameter is DN25, the perforation is not less than 4mm, and the water enters from the sedimentation end and is arranged in a ring to ensure uniform flushing.

[0039] Sludge return zone and return area: The interior of the box 1 is equipped with an external flushing pipe fitting, which includes a second main pipe 13 and two U-shaped pipes 9. The second main pipe 13 is fixedly connected to the box 1, and the second main pipe 13 is fixedly connected to the adjacent U-shaped pipe 9. A second perforated pipe 6 is fixedly connected between the two U-shaped pipes 9. Two sludge discharge hoppers 10 are symmetrically fixedly connected to the bottom of the box 1, and the second perforated pipe 6 is located inside the sludge discharge hopper 10.

[0040] The settler has a reflux zone that meets the solids throughput requirements and is equipped with an auxiliary reflux device. The flushing system consists of a second main pipe 13, a U-shaped pipe 9, a second perforated pipe 6, and a control valve installed on the second main pipe 13. The piping material is I-grade UPVC, the pipe diameter is DN25, the perforation is not less than 4mm, and the pipes enter from the end of the settler and are arranged in a ring vertically to the inlet channel for uniform flushing.

[0041] Water inlet area: Four water inlets 14 extending into the interior are provided on both sides of the outer wall of the tank 1, and the water inlet ends of the eight water inlets 14 are fixedly installed with the first regulating weir plate 7.

[0042] The sedimentation tank uses a uniquely designed double-sided, eight-channel system to evenly distribute water, ensuring equal flow rate and uniform water pressure at every point. Both sides of the inlet are equipped with a first regulating weir plate 7 to control the flow velocity at the inlet 14, working in conjunction with the second regulating weir plate 16 on the collection tank to achieve dynamic balance.

[0043] The water distribution system achieves uniform water distribution with minimal head loss, and there are no dead zones, drops, or gas introduction in the distribution channels.

[0044] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
