Description

Technical Field

[0001] This utility model relates to the field of sedimentation technology, and in particular to a combined fiberglass vertical flow sedimentation device. Background Technology

[0002] Vertical flow sedimentation tanks, as a key solid-liquid separation device, are widely used in the treatment of municipal sewage and industrial wastewater. Their basic working principle is to utilize gravity sedimentation to separate suspended solids from the water, thereby achieving water purification.

[0003] During operation, suspended solids in the wastewater settle by gravity and accumulate as sludge at the conical bottom of the sedimentation tank. To ensure continuous operation of the equipment, this accumulated sludge needs to be discharged periodically through the sludge discharge pipe at the bottom.

[0004] However, as sludge accumulates, especially in the narrow area near the discharge port, the gravity of the upper sludge and water continuously compacts the bottom sludge. Prolonged compaction leads to a decrease in sludge moisture content, causing the particles to adhere more tightly, eventually resulting in dewatering and hardening, forming a solid sludge blockage near the discharge port.

[0005] Once sludge blockage forms, conventional sludge removal operations cannot proceed smoothly. This not only causes blockage in the sludge discharge pipe but also severely affects the continuous and stable operation of the settler, sometimes requiring shutdown for manual cleaning, greatly increasing maintenance difficulty and operating costs. The existing settler structural design has significant shortcomings in actively preventing sludge caking. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a combined fiberglass vertical flow sedimentation tank, which aims to improve the problem of bottom sludge compaction and caking due to compaction, which leads to blockage of the sludge discharge port and difficulty in sludge discharge. This utility model aims to provide a combined fiberglass vertical flow sedimentation tank with an improved structure that can effectively solve the above problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a combined fiberglass vertical flow sedimentation tank, comprising: a tower, an inlet pipe fixedly connected to the outer wall of the tower, an outlet pipe fixedly connected to the upper part of the tower, a central pipe coaxially disposed inside the tower, and a sludge pipe fixedly connected to the bottom of the tower; and an anti-clogging mechanism disposed at the bottom of the tower.

[0008] The anti-clogging mechanism includes a gently sloping cone fixed to the bottom of the tower and a steeply sloping cone fixed to the lower end of the gently sloping cone; an aeration ring is fixed on the inner wall of the steeply sloping cone, the aeration ring is arranged around the inlet of the sludge pipe, and multiple aeration holes are opened on the ring body of the aeration ring.

[0009] Preferably, an overflow weir is fixed to the upper inner wall of the tower, and a filtration mechanism is provided between the outer periphery of the central tube and the overflow weir.

[0010] Preferably, the filtration mechanism includes a limiting ring fixed to the inner wall of the tower, and a filter plate detachably placed on the limiting ring; a filter screen is fixed on the upper surface of the filter plate, and a handle for lifting is also fixedly connected to the filter plate.

[0011] Preferably, the anti-clogging mechanism further includes an aeration pipe, one end of which passes through the wall of the tower and is sealed and connected to the aeration ring.

[0012] Preferably, the slope of the steep slope cone is greater than that of the gentle slope cone, and the lower outlet of the steep slope cone is connected to the sludge pipe flange.

[0013] Preferably, a reflector plate for uniformly distributing water flow is fixed at the lower outlet of the central tube.

[0014] Preferably, a ladder for personnel to climb is fixed on the outer wall of the tower.

[0015] Preferably, a protective cover is hinged to the top opening of the tower.

[0016] Preferably, the bottom of the tower is also fixedly connected to a base for support.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting an anti-clogging mechanism consisting of a gently steep double cone and an aeration ring at the bottom of the tower, the problem of easy sludge caking and blockage at the bottom of the existing sedimentation tank and the difficulty of sludge discharge is solved, and the technical effects of actively loosening sludge, ensuring smooth sludge discharge, and improving the stability of equipment operation are achieved.

[0022] Please refer to Figures 1 to 5 This utility model provides a combined fiberglass vertical flow sedimentation tank, which aims to solve the problems of easy sludge caking and blockage at the bottom of existing vertical flow sedimentation tanks and poor removal of floating matter in the upper layer.

[0023] like Figure 1 and Figure 2As shown, the combined fiberglass vertical flow sedimentation tank includes a tower 1, a base 5 fixedly connected to the bottom of the tower 1, a ladder 4 fixedly connected to the outer wall of the tower 1, a protective cover 8 hinged to the top opening of the tower 1, an inlet pipe 2 fixedly connected to the outer wall of the tower 1, an outlet pipe 3 fixedly connected to the upper part of the tower 1, a central pipe 10 coaxially arranged inside the tower 1, and a sludge pipe 6 fixedly connected to the bottom of the tower 1. The combined fiberglass vertical flow sedimentation tank also includes an anti-clogging mechanism 7 located at the bottom of the tower 1, which includes a gently sloping cone 7 fixedly connected to the bottom of the tower 1. 04, and a steep slope cone 705 fixed to the lower end of the gentle slope cone 704. The slope of the steep slope cone 705 is greater than that of the gentle slope cone 704. The lower outlet of the steep slope cone 705 is connected to the flange of the sludge pipe 6. An aeration ring 702 is fixed on the inner wall of the steep slope cone 705. The aeration ring 702 is arranged around the inlet of the sludge pipe 6. Multiple aeration holes 703 are opened on the ring body of the aeration ring 702. The anti-clogging mechanism 7 also includes an aeration pipe 701. One end of the aeration pipe 701 passes through the cylinder wall of the tower 1 and is sealed and connected to the aeration ring 702.

[0024] The filtration mechanism 9 includes a limiting ring 904 fixed to the inner wall of the tower 1, and a filter plate 902 detachably placed on the limiting ring 904. A filter screen 903 is fixed on the upper surface of the filter plate 902, and a handle 901 for lifting is also fixedly connected to the filter plate 902. This detachable placement of the limiting ring 904 and the filter plate 902, combined with the handle 901, ensures the installation stability of the filter plate 902 and the convenience of disassembly and maintenance. At the same time, in order to ensure a stable water flow, a reflector plate 12 for uniformly distributing the water flow is fixed at the lower outlet of the central pipe 10.

[0025] In one preferred embodiment, in order to stably deliver gas to the aeration ring 702, the anti-clogging mechanism 7 also includes an aeration pipe 701, one end of which passes through the cylinder wall of the tower 1 and is sealed and connected to the aeration ring 702; in another preferred embodiment, in order to optimize the sludge sliding and collection efficiency, the cone slope of the steep slope cone 705 is greater than that of the gentle slope cone 704, and the lower outlet of the steep slope cone 705 is detachably and sealed to the sludge pipe 6 through a flange.

[0026] As another preferred embodiment, in order to prevent the incoming water flow from directly impacting the bottom sludge and to achieve uniform water distribution, a reflector plate 12 is fixed at the lower end outlet of the central pipe 10. The reflector plate 12 is an upwardly convex conical plate.

[0027] As another preferred embodiment, in order to facilitate personnel to reach the top of the equipment for inspection and maintenance, a ladder 4 is welded and fixed to the outer wall of the tower 1.

[0028] As another preferred embodiment, in order to prevent external debris from falling into the tower 1 and to ensure personnel safety, a protective cover 8 is rotatably connected to the top opening of the tower 1 via a hinge.

[0029] As another preferred embodiment, in order to provide stable installation support for the entire tower 1, a base 5 is also fixedly connected to the bottom of the tower 1. The base 5 is an annular frame structure with anchor bolt holes.

[0030] Working principle: The wastewater to be treated enters the interior of the central pipe 10 through the inlet pipe 2 and flows downward. After reaching the reflector plate 12 at the lower end of the central pipe 10, the water flow is blocked and evenly distributed by the reflector plate 12, and then gently deflects and enters the wide settling zone of the tower 1. Due to the increase in the cross-sectional area of ​​the water flow, the water flow velocity is significantly reduced, and the suspended solids in the water begin to settle under the action of gravity. The settled suspended matter gathers into sludge, which slides down the inner walls of the gentle slope cone 704 and the steep slope cone 705 to the inlet of the sludge pipe 6. When sludge needs to be discharged or signs of caking appear, compressed gas is sent into the aeration ring 702 through the aeration pipe 701 and sprayed out from the multiple aeration holes 703 on the aeration ring 702. The bubbles formed violently agitate and loosen the sludge accumulated at the bottom, restoring its fluidity, so that it can be smoothly discharged through the sludge pipe 6. Meanwhile, the clear water that has settled in the upper layer continues to rise. As it flows toward the overflow weir 11, it passes through the filter screen 903. Lightweight floating objects or small suspended particles that have not settled are effectively intercepted by the filter screen 903 on the filter plate 902. The clear water, after further purification, eventually overflows the overflow weir 11, collects, and flows out from the outlet pipe 3.
