Description

Wide width chain flight type Non-metal sludge collector

The present invention relates to a wide chain flight type non-metal sludge collector, and more particularly, is lightweight and durable, reduces overlapping component parts, and expands the limited structure of the sedimentation tank, thereby reducing installation and maintenance. The present invention relates to a wide-chain-flight nonmetal sludge collector that is easy to use, and has a low level of failure and consequent delay.

Among the main facilities of water and sewage treatment plants, wide chain flight type nonmetal sludge collectors for removing foreign substances such as sludge introduced with water or sewage play an important role as primary and physical purification means.

That is, the wide chain flight type non-metal sludge collector is to scrape sludge and other foreign matter accumulated in the bottom of the sedimentation tank, which is a civil engineering structure in the form of a square tank, to be discharged to the outside of the settling tank.

1 is a partial cutaway perspective view of a conventional chain flight type sludge collector.

The conventional chain flight type sludge collector is divided into two channels around the driving unit 10 including a driving motor, and is disposed at an appropriate location with the chain 20 which transfers driving force from the motor and is disposed at an appropriate location. An appropriate number of guide shafts 31, 32, 33, 34 to switch the direction of movement, and a return rail portion (not shown) to allow the flights 40 to the bottom of the sedimentation tank to move toward the driving unit 10 again. Not included).

More specifically, by using the rotational force from the drive motor provided above the rectangular sedimentation tank, two rows of endless endless rows of these sprockets are rotated by rotating a plurality of shafts and sprockets mounted on each shaft in the width direction in the sedimentation tank. A separate collector (hopper) (H) provided on one side of the settling tank by scraping sludge, etc. accumulated on the bottom of the settling tank by moving the chain and the flight coupled to these endless chains at regular intervals in one direction. Move to.

Sludge and the like accumulated at the bottom of the sedimentation tank, in particular, in the case of sewage treatment plants, are not limited to simply containing water, but usually contain a large amount of mucus-soil with odor.

On the other hand, the chain flight type sludge collector having the conventional structure and function has the following problems.

First of all, all the components of the chain flight type sludge collector are composed of metals, especially iron (Fe), such as flights, chains and sprockets, so the weight of the chain flight type sludge collector is inevitably increased. .

That is, the initial installation work is difficult, as well as maintenance after installation is not easy.

In addition, since the sludge, ie, the dirt, is generally corrosive, the metal components constituting the chain flight type sludge collector are easily corroded.

In other words, by causing the premature aging of the chain flight type sludge collector, the occurrence of failures and the resulting delay of work, as well as the problem of greatly overlooking the overall appearance of the facility was never overlooked.

In addition, the chain flight type sludge collector has a problem in that the width of the channel and the constitution of the material is limited. In particular, the existing chain flight type sludge collector as a material and construction structure was limited to about 6M width of the channel due to the heavy material such as metal.

The width of the waterway is about 6M because of the drawback that the drive shaft holding the flight and the sprocket is bent due to the load, and if the load of the flight is heavy during operation, due to the failure due to the overload of the flight and the driving motor. There was no choice but to limit the width of the channel.

The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a wide-chain-flight nonmetal sludge collector which is lightweight and durable.

Still another object of the present invention is to provide a wide chain flight type nonmetal sludge collector which is not limited to the structural limitation (about 6M) of the chain flight type sludge collector.

In constructing a structure that does not limit the structural limitation, a wide chain flight type non-metal composed of a drive unit connected integrally with the drive shaft and installed on the upper slab, and a drive shaft connected to the main sprocket integrally formed with the driven sprocket and the driven sprocket. To provide a sludge collector.

In addition, it is to provide a flight incorporating a buoyant material that minimizes the bending of the flight due to the structural load of the wide chain flight type non-metallic sludge collector drive shaft and the load during work.

In addition, the width of the settling tank, which was limited (6M), is distributed to the upper slab by distributing the driving shaft portion to the upper slab, rather than a structure for directly rotating the driven sprocket by the conventional driving sprocket. Through the structure of the main sprocket consisting of the collecting sprockets to be transmitted, it was possible to make a wide sedimentation tank, and to solve the problem of bending of the driving shaft and uniform driving force transmission, which were problematic.

In addition, the problem caused by the widening of the flight to remove the dirt is to insert a buoyancy material (eg Schiropol) inside the holding guide connected to the flight, so that the flight is separated from the bottom of the settling tank due to the buoyancy of the buoyant material The load caused by

In addition, it is possible to maximize the time savings at the time of cost reduction and failure replacement by the effect of reducing the parts of the conventional settling tank to one part.
