BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scroll type traveling sludge collector, and more particularly to a scroll type traveling in which the efficiency of collecting and removing sludge is improved while minimizing and simplifying the size of the truck using a single driving motor when moving the truck. It is about a bulk sludge collector.

Chemical sedimentation basins adopted in most water treatment processes are usually injected with flocculants to increase the particle size and density and induce sedimentation in a short time. The function of these sedimentation basins is to reduce the load on flocs grown in the mixing / aggregation process as much as possible in subsequent processes.

There are a number of factors that affect the performance of the sedimentation basin. In particular, the biggest influence on flotation sedimentation is the hydraulic flow and design of the sludge collector.

In other words, the sludge collector has the most influence on the water treatment among the design factors of the sedimentation system.

The operation of the sludge collector also creates turbulence in the sludge in the sedimentation basin, and the sludge removal capacity of the sludge collector has a great influence on the sediment effluent water quality.

Such a phenomenon causes sludge that sinks in the lower part of the sedimentation basin to cause vortex due to the movement of the sludge collector or density flow generated in the ground, and the suspended sludge affects the sedimentation effluent quality. As such, the role of the sludge collector in the sedimentation basin is very important.

There are various types of sludge collectors currently used at home and abroad, and the sludge collectors used mainly in Korea include an underwater bogie type, a roller chain flight type, and a vacuum suction type.

Analyzing the problems for each of these facilities, first, the submersible bogie requires a lot of energy for the operation of the bogie, and when the sludge collector reaches the sedimentation basin, the amount of sludge increases and the submersible bogie moves on the running rail. It has a problem such as the sludge can not remove the sludge that can not be removed from the sludge, the roller chain flight type is a way to continuously remove the sludge while continuously circulating the orbit, it takes a lot of power costs, both sides When the roller chain of the support supporting the flight is broken, the flight rotates only on one side, and the other part is continuously separated from the driving unit, which causes fatal damage to the sludge collector device including the flight.

On the other hand, the vacuum suction type is a device in which the sludge and the water of the lower high pressure sedimentation basin is naturally suctioned to the upper part of the lower pressure using the pressure difference caused by the head difference between the upper part of the sedimentation basin and the lower part of the sedimentation basin.

This device has no energy loss because it is operated by the water head, but it can remove only the sludge with low solid concentration of sludge and treated water compared with the discharged sludge because the sludge is mixed with water and drawn out. It has the disadvantage of losing a lot. In addition, when the outside air temperature drops in winter, the water in the upper part of the sedimentation basin freezes, thus making operation impossible.

Sludge collectors should basically be inoperable, prevent damage to the system, and remove wastewater from the treatment plant by removing solids with low moisture content.

In addition, even when the sludge is generated due to poor water quality, the sludge should be capable of removing sludge efficiently without overwhelming the machine.

Looking at the progress and apparatus of the sewage treatment plant for the water treatment process as described above, as follows.

When the sewage or various wastewater is introduced into the sewage treatment plant, various floating matters floating on the water and various sediment settling under the water are removed by the screen device, and the sand contained in the water is removed from the sedimentation basin again.

As such, the wastewater after removing the impurities of relatively large particles is pumped to a position of a certain height and sent to the first sedimentation basin by a natural dropping oil method. The process of decomposing into an inorganic substance by the action is carried out.

In addition, wastewater purified to some extent from the initial settling basin is introduced into the aeration tank. In this aeration tank, oxygen is forced into the aeration and the aerobic bacteria grow and multiply in the wastewater to enter the final settling basin.

In the final sedimentation basin, the same sedimentation as in the initial sedimentation basin, sludge settled to the bottom of the sedimentation basin is sent to the concentration tank and collects and removes the bubbles floating on the surface of the water. The chlorine that is introduced into the chlorine input tank is discharged in the disinfected state.

As above, the sewage treatment plant treating sewage and various wastewaters in several stages is treated with the flowing inflow of wastewater continuously. Accordingly, in each sedimentation basin, sewage and wastewater are decomposed by the activated sludge method, so that many bubbles form on the water surface. Of course, it was necessary to remove the bubbles and sludge, as well as the sludge is settled to the bottom of the settling basin.

Therefore, conventionally, as well as collecting and removing such bubbles in each sedimentation basin, various kinds of devices for removing sludge that settle to the bottom surface have been developed and used.

That is, a typical round sludge collector, a midda sludge collector, a siphon type sludge collector, a flight sludge collector and the like have been known and used.

However, such sludge collectors have had various problems in collecting and removing the bubbles and sludges floating on the surface of the water.

In other words, when moving to collect the sludge, the sludge can be collected and removed only when moving forward, resulting in low work efficiency and inefficiency. There was a problem of deterioration.

In addition, the collected sludge was not discharged properly, and there was a need to remove it manually.

Applicant has invented an apparatus capable of efficiently collecting and removing bubbles and sludges on the surface of a sewage treatment plant in response to the above requirements.

The present invention has been made to solve the above problems, a single motor is installed to reduce the size of the sludge collector while minimizing the size of the sludge collector, the sludge collection and removal ability is excellent, and the cost of the device is configured to scroll-type running balance The purpose is to provide a sludge collector.
