Description

Technical Field

[0001] This utility model relates to the field of water tanks, and in particular to a multi-layer sedimentation water tank. Background Technology

[0002] In industries such as waste-to-energy incineration, metallurgy, and mining, the residue (slag) from high-temperature furnace incineration typically contains recyclable sand and gravel particles (such as coarse sand and fine sand) and non-ferrous metals (such as iron, aluminum, copper, and stainless steel). After crushing, sorting, and screening, these slags can be recycled to recover high-value metal resources, while the separated sand and gravel particles can be used to produce building materials such as environmentally friendly bricks and landscape bricks, realizing the resource utilization of solid waste and reducing environmental pollution.

[0003] Currently, wet sorting processes are commonly used in slag treatment, employing methods such as hydraulic washing and sedimentation to separate sand and metal particles of different sizes from the mixed slurry. The settling tank is a key solid-liquid separation device, its function being to allow solid particles (sand, metal) in the wastewater to settle to the bottom via gravity sedimentation, while the clear water overflows or is recycled. To improve sedimentation efficiency, multi-layer settling tanks are widely used. These tanks employ multiple sets of settling plates, allowing wastewater to settle layer by layer, thereby increasing the chances of particle settling and improving separation efficiency.

[0004] However, the size of the settling holes on existing settling plates is usually fixed. This means that the same equipment cannot efficiently treat wastewater with a wide range of solid particle sizes or large variations in particle size. When the particle size is significantly larger than the settling hole size, blockage is very likely to occur, requiring frequent shutdowns for cleaning; when the particle size is much smaller than the settling hole size, the settling efficiency will be greatly reduced, and small particles cannot be effectively retained, resulting in substandard effluent quality.

[0005] Users typically need to prepare and replace settling plates with different aperture sizes for particles of a specific size. This is not only cumbersome and time-consuming, increasing maintenance costs, but also reduces the versatility and flexibility of the equipment. Furthermore, in multi-layer settling structures, particles settled from the lower settling plates can easily "flip over" or "reflow" back into the upper settling space through the holes in the lower settling plates under the influence of continuous sewage flow or water flow disturbance. This backflow greatly reduces the actual settling efficiency and increases the settling time required. Utility Model Content

[0008] The water tank body has a box-like structure with an open top;

[0037] 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.

[0038] This utility model provides, for example Figure 1-6 The multi-layered settling tank shown includes: a tank body 1, which has a box-like structure with an open top; adjustable settling devices 2, multiple adjustable settling devices 2 are horizontally and parallelly installed inside the tank body 1, and adjacent adjustable settling devices 2 are staggered; an adjusting linear adjustment device 3 is installed at the bottom of the adjustable settling devices 2, and is used to adjust the size of the holes on the adjustable settling devices 2; and a sliding limit device 4 is installed at the bottom of both sides of the adjustable settling devices 2, which facilitates the adjustment of the sliding limit device 2 by adjusting the linear adjustment device 3. The position of plate 22 relative to the fixed single-sided settling mechanism 21 is adjusted so as to adaptively adjust the size of the settling hole at the overlap of the inner cavity of the first through hole 2121 and the second through hole 221, so as to adapt the settling according to the size of the sand and gravel particles, making the settling more flexible. Since the settling holes between adjacent adjustable settling devices 2 are staggered, it is easy to prevent the settled sand and gravel from turning over and flowing back to the upper adjustable settling device 2. Both sides of the water tank body 1 are equipped with discharge pipes 5, and the discharge pipes 5 are located above the adjusting linear adjustment device 3, so as to facilitate the discharge of the sand and gravel settled on the adjustable settling device 2.

[0039] Furthermore, the adjustable settling device 2 includes: a fixed single-sided settling mechanism 21, which is fixedly installed inside the water tank body 1; and a sliding adjustment plate 22, which is slidably disposed on the lower surface of the fixed single-sided settling mechanism 21. The fixed single-sided settling mechanism 21 includes: a fixed plate 211, which is fixedly installed inside the water tank body 1; and a settling plate 212, which is fixedly connected to one side of the fixed plate 211 and is fixedly installed inside the water tank body 1. The settling plate 212 has multiple first through holes 2121 evenly spaced, and the sliding adjustment plate 22 has multiple second through holes 221 evenly spaced. The area where the inner cavities of the first through holes 2121 and the second through holes 221 overlap is the settling hole. By moving the sliding adjustment plate 22 relative to the settling plate 212, the solid part of the sliding adjustment plate 22 can block the inner cavity of the first through holes 2121, allowing particles to settle through the settling hole where the inner cavities of the first through holes 2121 and the second through holes 221 overlap. The settling holes of adjacent adjustable settling devices 2 adopt a staggered layout design. This structure mainly achieves the effect of preventing backflow of settled particles through the principle of physical blocking. Specifically, when there is a certain offset between the hole position of the lower adjustable settling device 2 and the hole position of the upper adjustable settling device 2 on the vertical projection plane, the solid part of the lower adjustable settling device 2 can effectively block the upper hole. When wastewater carrying solid particles flows through the sedimentation system, larger particles fall to the lower layer under gravity through the upper sedimentation holes. If, under conditions of water flow disturbance or equipment vibration, the settled particles in the lower layer tend to float, these particles will be mechanically blocked by the physical components of the adjustable sedimentation device 2 in the lower layer, preventing them from directly forming a backflow channel through the upper holes. This staggered hole arrangement essentially constitutes a multi-level physical barrier system, forcing the floating particles to repeatedly settle between the adjustable sedimentation devices 2 in each layer, ultimately being effectively trapped in the bottom collection area. Compared to the traditional aligned hole design, this structure significantly reduces the probability of particles returning to the upper layer, achieving a simultaneous improvement in sedimentation efficiency and backflow prevention performance.

[0040] The linear adjustment device 3 includes: a lead screw 31, which is rotatably connected to the water tank body 1, and a nut seat is threaded onto the lead screw 31; a movable plate 32, on which the nut seat is fixedly installed, and the movable plate 32 is fixedly connected to the sliding adjustment plate 22; and a fixed frame 33, which is fixedly installed on the inner side of the water tank body 1, and a fixed block is fixedly installed on the fixed frame 33. The lead screw 31 is rotatably connected to the fixed block, and the lead screw 31 is rotatably connected to the water tank body 1 through a waterproof bearing. The threaded engagement between the lead screw 31 and the nut seat facilitates the linear movement of the movable plate 32 by rotating the lead screw 31, enabling the movable plate 32 to drive the sliding adjustment plate 22 to move linearly. The installation of the fixed frame 33 and the fixed block makes the rotation of the lead screw 31 more stable.

[0041] The sliding limiting device 4 includes: a sliding guide rail 41, which is fixedly installed on the lower surface of the fixed single-sided settling mechanism 21 and is L-shaped; and ball bearings 42, which are rolled and embedded in the bottom of the sliding guide rail 41. The symmetrically arranged sliding guide rails 41 facilitate the limiting of the linear sliding of the sliding adjustment plate 22, making the linear sliding of the sliding adjustment plate 22 more stable. The rolling support of the ball bearings 42 on the sliding adjustment plate 22 makes the sliding of the sliding adjustment plate 22 smoother.

[0042] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
