Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a wastewater filtration tank that is easy to clean. Background Technology

[0002] Wastewater filtration tanks, as an indispensable component of water treatment systems, play a crucial role in interception, protection, purification, and regulation during the water treatment process. However, as wastewater treatment time increases, solid particles such as silt, rust, and algae gradually accumulate on the surface and pores of the filter screen, causing the pore size to decrease or even become clogged. Therefore, regular cleaning of the filter screen is necessary. However, in existing wastewater filtration tank structures, the filter screen is fixed in the tank with bolts. When the filter screen needs cleaning or replacement, multiple bolts must be disassembled to remove it for manual cleaning, which is cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0003] The main purpose of this utility model is to provide a sewage filtration tank that facilitates filter screen cleaning, thereby effectively improving the ease of cleaning the filter screen.

[0004] Therefore, the present invention provides a wastewater filtration tank for easy cleaning of filter screens, comprising a filtration tank, wherein multiple filter screens are arranged in the filtration tank along the water flow direction, and slots are symmetrically installed on opposite side walls of the filtration tank, with both ends of the filter screens respectively inserted into the slots. A filter screen cleaning tank is provided on one side of the filtration tank, and a lifting assembly is provided at the top of the filtration tank for lifting the filter screens out of the filtration tank and moving them to the filter screen cleaning tank. The lifting assembly includes a frame, a slide rail provided at the top of the frame, a slider slidably arranged on the slide rail, a drive component for driving the slider to move, and a winch fixedly installed on the slider. A hook is provided on the hoisting rope of the winch, and a hanging point that cooperates with the hook is provided at the top of the filter screen.

[0005] Specifically, the driving component is a lead screw mechanism driven by a motor.

[0006] Specifically, the aperture of the multiple filter screens decreases sequentially along the water flow direction.

[0007] Specifically, a sedimentation tank is provided on the other side of the filtration tank, and the wastewater filtered by the filter screen flows into the sedimentation tank through the overflow port.

[0008] Compared with the prior art, this utility model has the following advantages: The filter screen is installed in the filter tank by plugging it in. When the filter screen needs to be cleaned, a winch is used to lift the filter screen out of the filter tank. Then, a drive unit is used to move the slider along with the lifted filter screen to the top of the cleaning tank. After that, the winch lowers the filter screen into the cleaning tank and moves the filter screen up and down in the cleaning tank to clean it. After the filter screen is cleaned, it is lifted out of the cleaning tank and moved back to the top of the filter tank. The filter screen is then aligned with the slot and lowered down, and can be reinserted into the slot. The cleaning and installation of the filter screen is convenient and quick.

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.

[0015] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] See Figure 1 and Figure 2 A wastewater filtration tank for easy cleaning of filter screens includes a filtration tank 1, in which multiple filter screens 2 are arranged along the water flow direction. Grooves 3 are symmetrically installed on opposite side walls of the filtration tank 1, with the two ends of the filter screens 2 respectively matched and inserted into the grooves 3. A filter screen cleaning tank 4 is provided on one side of the filtration tank 1. A lifting assembly 5 is provided at the top of the filtration tank 1 for lifting the filter screens 2 out of the filtration tank 1 and moving them to the filter screen cleaning tank 4. The lifting assembly 5 includes a frame 501, a slide rail 502 set at the top of the frame 501, a slider 503 slidably set on the slide rail 502, a drive component 504 for driving the slider 503 to move, and a winch 505 fixedly installed on the slider 503. A hook 6 is provided on the hoisting rope of the winch 505, and a hanging point 7 that cooperates with the hook 6 is provided at the top of the filter screens 2. The arrows in the figure indicate the water flow direction. An inlet is provided on the upstream side of the filtration tank 1, and an outlet is provided on the downstream side.

[0018] When the filter screen 2 needs to be cleaned, move the winch 505 directly above the corresponding filter screen 2, connect the hook of the hoisting rope to the hanging point 7, start the winch 505, and use the winch 505 to lift the filter screen 2 from the top of the filter tank 1. Then, use the drive component 504 to drive the slider 503, along with the lifted filter screen 2, to move directly above the cleaning tank. After that, the winch 505 lowers the filter screen 2 into the cleaning tank and moves the filter screen 2 up and down in the cleaning tank to clean the filter screen 2 with the cleaning fluid. After the filter screen 2 is cleaned, lift the filter screen 2 out of the cleaning tank and move it back above the filter tank 1. Align the filter screen 2 with the slot 3, lower the filter screen 2, and reinsert the filter screen 2 into the slot 3 to complete the installation of the filter screen 2. The cleaning and installation process of the filter screen 2 is convenient and quick.

[0019] Understandably, the drive component 504 can be a screw mechanism driven by a motor, with the slider 503 threadedly connected to the screw of the screw mechanism. The motor is fixedly mounted on the frame 501, and the motor shaft is fixedly connected to the screw via a coupling. Of course, the drive component 504 can also be a linear motor.

[0020] In some embodiments, the aperture of multiple filter screens 2 decreases sequentially along the water flow direction. By adopting graded filtration, impurities can be removed step by step, improving filtration accuracy and extending the service life of the filter screens 2.

[0021] See Figure 1 and Figure 2 On the other side of the filter tank 1, there is a sedimentation tank 8. Wastewater filtered by the filter screen 2 flows into the sedimentation tank 8 through the overflow outlet. In the sedimentation tank 8, suspended solid particles in the water are removed by gravity settling, achieving solid-liquid separation and purifying the water. The wastewater that has undergone sedimentation treatment can then enter the next stage of water treatment device for further treatment.
