Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an inclined tube sedimentation tank structure. Background Technology

[0002] In wastewater treatment plants, sedimentation tanks are used for wastewater sedimentation. After influent wastewater undergoes filtration and biological reactions in the biological treatment tank, it enters the sedimentation tank for further sedimentation. Sedimentation tanks with inclined tubes in the sedimentation zone are called inclined tube sedimentation tanks. These tanks, in the case of horizontal or vertical flow sedimentation tanks, utilize inclined parallel tubes or pipes (sometimes honeycomb packing) to divide the sedimentation zone into a series of shallow sedimentation layers. During treatment, wastewater enters the sedimentation tank from the lower end of the inclined tubes and overflows from the overflow hole at the top. This allows the sediment in the wastewater to be better retained within the sedimentation tank by the action of the inclined tubes, thus improving the sedimentation effect.

[0003] However, when sedimentation tanks treat wastewater, the substances to be settled in the wastewater are constantly changing (for example, the substances to be settled vary with the season, and the types and quantities of these substances also differ). Existing technologies often employ multiple sedimentation tanks, which increases the required area and space, and raises operating costs. In existing patents, Chinese patent application (CN101002993) discloses a multi-layered variable-angle inclined plate or inclined tube sedimentation tank. This tank consists of multiple inclined tubes with different inclination angles stacked in layers within the tank. This creates mutual obstruction between the opposing openings of the inclined tubes, resulting in insufficient flow and low sedimentation efficiency. Furthermore, the angle of the inclined tubes cannot be adjusted, making it unsuitable for the sedimentation of different types of wastewater.

[0004] Therefore, how to design an inclined tube sedimentation tank structure that allows for easier adjustment of the inclination angle of the inclined tubes within the tank, resulting in higher sedimentation quality, higher efficiency, and greater adaptability has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to design an inclined tube sedimentation tank structure that can more easily adjust the inclination angle of the inclined tubes in the tank, resulting in higher sedimentation quality, higher efficiency, and stronger adaptability.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an inclined tube sedimentation tank structure, comprising a rectangular tank body on a horizontal plane, a first fixing member and a second fixing member horizontally arranged inside the tank body, and the first fixing member and the second fixing member are spaced apart along the depth direction of the tank body; a plurality of first inclined tubes and a plurality of second inclined tubes are densely distributed on the first fixing member and the second fixing member, such that the upper ends of the first inclined tubes and the second inclined tubes are inclined in opposite directions; the characteristic is that the ends of the first fixing member and the second fixing member on the same side are each hinged to the side wall of the tank body through a hinge structure that allows vertical rotation; a tension mechanism is provided on the tank body at the other end corresponding to the first fixing member and the second fixing member, the tension mechanism having a tension application end connected to the ends of the first fixing member and the second fixing member, and capable of driving the first fixing member and the second fixing member to rotate vertically, so that the angle of the first inclined tubes and the second inclined tubes relative to the horizontal direction changes.

[0007] In this way, during use, the aforementioned inclined tube sedimentation tank structure allows the first and second fixed components to rotate vertically via a tension mechanism. This rotation also causes the first and second inclined tubes on these components to change their inclination angles. This allows the inclined tube sedimentation tank to better adapt to wastewater sedimentation in different seasons. When the substances to be precipitated in the wastewater change, the angles of the first and second inclined tubes can be adjusted to better suit the sedimentation process. Furthermore, when the amount of precipitated substances changes, the inclination angles of the first and second inclined tubes can be adjusted as needed. Therefore, this structure allows for easier adjustment of the inclination angles of the inclined tubes within the tank, thereby improving sedimentation quality, efficiency, and adaptability to different sedimentation treatment requirements.

[0008] As an optimization, both the first fixing member and the second fixing member are designed as flat box structures; the first inclined tube and the second inclined tube are respectively disposed inside the first fixing member and the second fixing member, and the upper and lower end faces of the first inclined tube and the second inclined tube are respectively coplanar with the upper and lower surfaces of the first fixing member and the second fixing member.

[0009] In this way, the structure of the first and second fixing components is simpler and the design is more reasonable; and it is easier to clean the first and second inclined tubes.

[0010] As an optimization, the hinge structure includes a hinge protrusion that is horizontally protruding outward at the ends of the first and second fixing members, and hinge seats are provided on the side wall of the pool corresponding to the two ends of the hinge protrusion, and the hinge protrusion and the two hinge seats are hinged together by a rotating shaft.

[0011] This makes the hinged structure simpler and easier to install and set up.

[0012] As an optimization, the tension structure includes two longitudinally spaced drum mechanisms at the upper end of the pool body. The working ends of the drum mechanisms are connected to pull ropes, and the distal ends of the pull ropes are disposed downwards within the pool body and connected to the ends of the first and second fixing components.

[0013] This arrangement of the tension structure is more reasonable, making the vertical rotation of the first and second fixed components more stable and easier to operate.

[0014] As an optimization, a fixed pulley is rotatably installed on the upper end of the side wall of the pool via a bracket, and the upper end of the pull rope passes around the fixed pulley and is connected to the drum mechanism.

[0015] By setting a fixed pulley, the rope can be prevented from contacting the upper part of the pool side wall, thus avoiding damage to the rope and the pool, making the design more reasonable.

[0016] As an optimization, the drum mechanism includes a support frame fixedly installed at the upper end of the pool body, and a drum that can be vertically rotated on the support frame. The upper end of the pull rope is wound around and fixed to the outer peripheral wall of the drum.

[0017] This makes the structure simpler, the design more reasonable, and the installation easier.

[0018] As an optimization, a first connecting hole and a second connecting hole are vertically opposite each other at the ends of the first fixing member and the second fixing member. A pull rod is provided in the second connecting hole, and the lower end of the pull rod is provided with a pull rod head and is supported against the lower side of the second fixing member. The upper end of the pull rod passes upward through the second connecting hole and is connected to the lower end of the pull rope. A vertical limiting cylinder is sleeved on the pull rod. The limiting cylinder is located between the first fixing member and the second fixing member, and the upper and lower ends of the limiting cylinder are respectively supported against the first fixing member and the second fixing member.

[0019] In this way, the lower end of the pull rope is designed with a pull rod and a limiting cylinder, which makes it easier for the pull rope to be connected to the first fixed component and the second fixed component.

[0020] As an optimization, the first connecting hole is a stepped hole structure with a larger diameter at the lower end and a smaller diameter at the upper end, and the upper end of the limiting cylinder can pass through the lower end of the first connecting hole and abut against the limiting step surface formed by the upper and lower ends of the first connecting hole; and the outer peripheral wall of the limiting cylinder is provided with external threads, and an adjusting nut is provided on the limiting cylinder with threaded engagement, and the upper end face of the adjusting nut can abut against the lower surface of the first fixed component.

[0021] This makes it easier to adjust the initial tilt angle of the first fixing component by adjusting the nut, so that the first fixing component can have different tilt angles and can better adapt to sedimentation treatment under different conditions.

[0022] As an optimization, the adjusting nuts are two that are stacked vertically.

[0023] This design is more reasonable and provides more reliable support for the first fixed component.

[0024] As an optimization, the vertical dimension of the first inclined tube is larger than the vertical dimension of the second inclined tube.

[0025] This allows for better fulfillment of sedimentation requirements under different circumstances.

[0026] In summary, the above-mentioned inclined tube sedimentation tank structure has the advantages of more convenient adjustment of the inclination angle of the inclined tubes in the tank, higher sedimentation quality, higher efficiency, and stronger adaptability. Attached Figure Description

[0036] This makes the hinged structure simpler and easier to install and set up.

The working end of the roller mechanism is connected to a pull rope 9, and the far end of the pull rope is disposed downward in the pool body and the lower end is connected to the end of the first fixing member and the second fixing member.

[0038] This arrangement of the tension structure is more reasonable, making the vertical rotation of the first and second fixed components more stable and easier to operate.
