Description

Technical Field

[0001] The utility model relates to the field of clarifiers, in particular to a high-efficiency mechanical stirring clarifier. Background Art

[0002] A mechanically agitated clarifier is a water purification structure that integrates coagulation, reaction, and sedimentation. It is mainly used for solid-liquid separation in the water treatment process. It uses mechanical agitation to cause solid impurities in the raw water to contact and flocculate with the formed sludge, and achieves solid-liquid separation in the separation chamber. Due to its high treatment efficiency and stable effluent quality, the mechanically agitated clarifier is widely used in industrial wastewater treatment, municipal sewage treatment, drinking water treatment and other fields.

[0003] In the existing technology, the clarifier mainly uses mechanical stirring to make the suspended particles in the raw water fully react with the added reagents to form flocs, and realize solid-liquid separation in the separation area. However, during stirring, there is usually only one stirring rod for stirring, causing the water to flow in only one direction, which makes it difficult for the sludge in the water to smoothly fuse with the flocculant to react into flocs. Utility Model Content

[0004] In order to make up for the shortcomings of the existing technology, there is only one stirring rod for stirring, which causes the water to flow in only one direction, making it difficult for the sludge in the water to smoothly fuse with the flocculant to react into flocs. The utility model proposes a high-efficiency mechanical stirring clarifier.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a high-efficiency mechanical stirring clarifier, comprising a clarifier, a top plate is fixedly connected to the top of the clarifier, and a stirring mechanism is provided in the inner cavity of the clarifier;

[0006] The stirring mechanism includes a motor, the bottom of the motor is fixedly connected to the top of the top plate, the output shaft surface of the motor passes through the bottom of the top plate, the output shaft surface of the motor is fixedly connected to the first stirring rod, the bottom of the top plate is rotatably connected to the second stirring rod, the surface of the first stirring rod is sleeved with a first belt, the bottom of the top plate is rotatably connected to the first rotating block, the inner cavity of the first belt is sleeved on the surface of the first rotating block, the surface of the first rotating block is fixedly connected to the first gear, the surface of the second stirring rod is fixedly connected to the second gear, and the teeth of the second gear are meshed with the teeth of the first gear.

[0007] Preferably, the bottom of the top plate is rotatably connected to a second rotating block, the surface of the second rotating block is sleeved with a second belt, the inner cavity of the second belt is sleeved on the surface of the first stirring rod, the surface of the second rotating block is fixedly connected to a third gear, the inner cavity of the clarification tank is rotatably connected to an inner ring gear, the teeth of the inner ring gear are meshed with the teeth of the third gear, and the bottom of the inner ring gear is fixedly connected to a scraper rod.

[0008] Preferably, a first hollow groove is formed on the surface of the inner gear ring, a fixed ring block is provided in the inner cavity of the first hollow groove, and the surface of the fixed ring block is fixedly connected to the inner cavity of the clarifier tank.

[0009] Preferably, a second hollow groove is opened on the surface of the top plate, the inner cavity of the second hollow groove is rotatably connected to a limiting block, and the bottom of the limiting block is fixedly connected to the top of the second rotating block.

[0010] Preferably, a third hollow groove is provided on the surface of the second stirring rod, a support rod is provided in the inner cavity of the third hollow groove, and the bottom of the support rod is fixedly connected to the inner cavity of the clarification tank.

[0011] Preferably, a connecting block is provided at the bottom of the second belt, and the top of the connecting block is fixedly connected to the bottom of the second rotating block.

[0013] The utility model is beneficial in that:

[0014] The utility model drives the first stirring rod to rotate by the motor, and the first stirring rod drives the first rotating block to rotate through the first belt, and the first rotating block drives the first gear to rotate together, and at the same time the first gear drives the second stirring rod to rotate in the opposite direction through the second gear. At this time, the first stirring rod and the second stirring rod rotate in the opposite direction to stir the water inside the clarifier, so that the sludge in the raw water can be mixed with the flocculant to form floccules, thereby realizing solid-liquid separation. Moreover, since the second stirring rod and the first stirring rod rotate in the opposite direction, the raw water inside the clarifier can form water flows in two directions, and the sludge in the raw water will not only move along the water flow in one direction, but can be affected by the reverse water flow, so that it can be better mixed with the flocculant in the water, thereby achieving the effect that the sludge can be better mixed with the flocculant in the water, and solves the problem that there is only one first stirring rod for stirring, which causes the water flow to flow in only one direction, making it difficult for the sludge in the water to smoothly fuse with the flocculant to react into floccules.

[0025] The motor 301 can be used to drive the first stirring rod 302 to rotate, so that the first stirring rod 302 can stir the raw water inside the clarifier 1, so that the sludge in the raw water can be mixed with the flocculant to form flocs, thereby achieving solid-liquid separation.
