Description

Removal apparatus of a scum}

The present invention relates to a scum collection device, more specifically, a scum collection device that can automatically transport the scum collected in one transverse direction to the bucket by the scum collection device installed in the water purification plant, sewage treatment plant, etc. It is about.

In general, as residential life becomes more convenient, there is a growing interest in environmental pollution, and it is well known that people want to live in a cleaner and hygienic environment. In order to meet these demands, various efforts are being made such as the development of sewage and wastewater treatment devices to clear river water as a water source, and treatment equipment for water and sewage.

The treatment devices are purified through various processes (eg, mixing / aggregation process, chemical treatment process, precipitation process, filtration process, sterilization process), and so on, so as to provide clearer water to end users. Various studies on the water treatment technology have been made.

In general, water purification plants, sewage treatment plants, wastewater treatment plants, and lake water quality improvement methods are administered by chemical and biological treatment to make small contaminants, and then attach fine bubbles to the contaminant chunks by flotation tanks. It is made smaller and floats on the surface of the water to separate from the clean water.

In this case, the floating separation tank discharges the pressurized dissolved water at a constant pressure in the floating separation tank to generate micro bubbles, and the micro bubbles adhere to the contaminants contained in the raw water and float upwards.

The contaminants that emerge as described above are commonly referred to as 'scum' and scum removal devices are installed in water purification plants or infertility treatment plants to remove such scums.

The scum removing device is operated to transfer the scum in one direction while the skimmer moves to the left and right of the water purification plant by a motor device, and scum collected in one side in accordance with the flow of water by installing a bucket in the direction of water flow. The scum was collected naturally, or the scum was collected by manually spraying water.

However, the natural method of transporting the scum in the transverse direction according to the flow of water is not only influenced by the wind, but also takes a long time to be transported, causing the scum to stick to the wall of the water purification plant.

In addition, the method of collecting the scum in the bucket by transporting the scum in the lateral direction by manually spraying the water can give a lot of inconvenience to the worker, there was a disadvantage in reducing the work efficiency.

Therefore, there is a demand for a separate device capable of automatically transferring a scum transferred to one side of the water purification plant by a skimmer to a bucket provided on one side of the water purification plant.

The present invention was devised to solve the above problems, a skimmer installed on the water surface to remove the scum floating on the water surface of the water purification plant, and the skimmer is moved to both sides of the water purification plant by the driving force of the forward / rotary motor. As a skimmer moving means to store the scum moved to one side of the water surface of the water purification plant by the skimmer, as well as a bucket that can be lifted / lowered according to the height of the water surface, as a discharge means for discharging the scum stored in the bucket to the outside In the configured scum collection device, characterized in that it further comprises an air injection type scum transfer means for sequentially injecting air to the scum moved to one side of the water purification plant by the skimmer 12 to the bucket (30) It is done.

Here, the air injection type scum transfer means, the limit switch 41 provided on both sides of the guide rail (11) to which the skimmer 12 is moved; A blower 42 provided at one side of the water purification plant 1 to supply compressed air by the detection signal of the limit switch 41; Compressed air is filled by the blower 42 and air transfer pipes 43 are installed on both sides of the water purification plant 1 in a transverse direction; A plurality of air injection holes 44 provided at predetermined intervals in the air transfer pipe 43; A plurality of cylinder valves 45 provided to open and close the plurality of air injection holes 44; It may be preferable that the PLC control unit 40 controls to sequentially open the plurality of cylinder valves 45 by the detection signal of the limit switch 41.
