Description

HUB ASSEMBLY FOR AGITATOR EASY TO DISASSEMBLE AND ASSEMBLE BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a hub assembly for a stirrer. More particularly, the present invention relates to a hub assembly for an agitator, which is easy to disassemble and attach to a stirring shaft in an agitator, and which can be engaged with any point on the agitating axis, thereby facilitating disassembly and assembly.

Due to the increasing need for environment, water quality standards are being strengthened, and recently, regulations on nitrogen and phosphorus are being strengthened. In addition, the role of public sewage treatment facilities is becoming more important if the water quality entering the sewage treatment plant is expected to deteriorate due to national trends in urbanization. There are various microorganisms in the natural water system that decompose and remove organic matter. When the sewage containing organic matter is discharged into natural waters such as rivers, the microorganisms attached to the stones degrade the organic matter in the water. Biological treatment of the sewage uses the principle of the natural action of the natural world, and mainly uses microorganisms Thereby removing organic matter, nitrogen and phosphorus in the sewage. In order to remove nitrogen, phosphorus, etc., anaerobic treatment is essential and a low-speed rotary stirrer is used to prevent the oxygen in the air from melting through stirring. If the speed of the impeller tip is too fast, appropriate impeller tip speed is needed because the sludge particles formed by the effect of turbulence and vortex can be destroyed. The flow in the reactor shows uneven flow characteristics due to factors such as short - circuit current and sagittal region, and such uneven flow has a great influence on the subsequent process.

/일 이상일 경우 총질소(T-N) 방출량은 20mg/L 이하, 총인(T-P) 방출량은 0.2 ~ 0.5 mg/L 이하로 더욱 강화된 방류수 수질 기준의 적용을 받게 됨에 따라 고도처리시설의 성능개선이 반드시 필요한 사항이다.Since January 2008, water quality standards for effluent have been strengthened, and existing facilities are being converted to advanced treatment facilities. However, due to site problems, bioreactors are being constructed with deep structure (over 10m). From January 2012, the sewage treatment capacity is 500

/ Day, it is necessary to improve the performance of the advanced treatment facility as the total nitrogen (TN) emission is less than 20 mg / L and the total phosphorus (TP) emission is less than 0.2 ~ 0.5 mg / L It is necessary.

However, if a suitable agitation facility is not applied to the bioreactor, it causes many problems such as poor mixing (failure to maintain uniform MLSS), loss of operation power, microbial death, and bulking.

In particular, according to Korean Patent Laid-Open No. 10-2003-0058882 ("Hydrofoil impeller for flocculating machine"), not only the structure of the impeller 3 but also the structure of the hub 1 are disclosed. In this publication, There is a problem that it is impossible to move (adjust the height) to any point of the stirring shaft in the future when the hub 1 is integrally formed and once mounted.

In addition, when the hub 1 coupled to the stirring shaft (not shown) fails or requires repair, disassembly of the hub 1 is difficult.

The present invention has been devised in order to solve such a problem, and the present invention has been made to solve the above problems, and it is an object of the present invention to provide an agitator which is easy to disassemble and to assemble, So as to provide a hub assembly.

According to the present invention, there is provided a hub structure, comprising: a hub body formed in a cylindrical cross-sectional shape and having a central portion in a hollow shape, the hub body being divided into two or more; And a hub flange connected to one side of the hub body and extending outwardly, wherein the hub flange is coupled to the impeller, the stirring shaft is coupled through the central portion of the hub body, The present invention provides a hub assembly for an agitator which is easy to disassemble and assemble.

The hub body includes a first body, a second body, and a third body that are separated at regular intervals along the circumference.

Meanwhile, the first body, the second body, and the third body are formed with coupling grooves penetrating the upper and lower ends to disassemble and assemble each other, and fastening means is fastened to the coupling grooves, The first body, the second body, and the third body are coupled to each other.

The hub assembly according to the present invention has an effect that it is easy to detach and attach the stirring shaft in the stirrer, so that it can be easily repaired or replaced when a failure or replacement occurs.

Also, since the hub assembly according to the present invention can be detached and attached to the stirring shaft, the hub assembly can be combined with the stirring shaft without being greatly affected by the diameter of the stirring shaft.

In addition, when one or more impellers are coupled to the stirring shaft, the hub assembly according to the present invention can be combined with any point on the stirring shaft, and the height can be adjusted.

1 to 3, a hub assembly 10 according to an embodiment of the present invention includes a hub body 100 and a hub flange 200.

The hub assembly 10 is widely used for agitating a flocculation tank for a water purification plant, a flocculation tank, an anaerobic denitrification tank, etc., such as a sewage treatment plant or a wastewater treatment plant. 4, the hub assembly 10 is coupled with the impeller 400 and the stirring shaft 300 in an agitator such as an agglomerator or a reaction tank, and is used to stir the solution in the agitator.

The hub body 100 is formed in a cylindrical cross-sectional shape, and the central portion is formed in a hollow shape, but is divided into two or more pieces. 4, the stirring shaft 300 is coupled through a central portion of the hub body 100, and the hub body 100 is configured to facilitate disassembly with the stirring shaft 300. As shown in FIG.

The hub body 100 may include a first body 110, a second body 120, and a third body 130 that are separated at regular intervals along the circumference. The first body 110, the second body 120, and the third body 130 have coupling grooves 111, 112, 121, 122, and 131 penetrating the upper and lower ends thereof for disassembly and assembly. 132, and fastening means (not shown) are coupled to the coupling grooves so that the first body 110, the second body 120, and the third body 130 are coupled to each other.

A first coupling groove 111 and a second coupling groove 112 are formed at an upper end portion and a lower end portion of the first body 110.
