Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic washing apparatus for a motor pump,

The present invention relates to a filtering device for automatically cleaning a filtering element of a motor pump for pumping water. More particularly, the present invention relates to a filtering device for filtering a foreign substance contained in a fluid sucked by a motor pump, And more particularly, to a filter cleaning apparatus for cleaning a filter of a motor pump capable of increasing the efficiency of pumping efficiency and maintenance.

2. Description of the Related Art [0002] In general, an underwater motor pump is a device installed in water for forcedly sucking and flowing a fluid such as waste water or drainage. Such a motor pump directly connects an electric motor that provides a driving force to one side of a pump performing a pumping action, A centrifugal pump, a multi-stage turbine pump, an axial flow pump, a sewage pump, a bladeless pump, etc. are used as the structure of the pump. Since the rotating part is in water, there is no noise and vibration, It is easy to handle and is widely used in sewage, sewerage, water supply and domestic wells.

In addition, the electric motor has a structure of an appendage type, a watertight type, and the like for water resistance, and the shaft bearing of the pump is also water-lubricated, so it is not necessary to supply oil.

That is, the submersible motor pump is strongly resistant to corrosion due to the nature of being installed in water and is manufactured with good airtightness. In general, the submersible motor pump is provided with a motor installed at one side in the longitudinal direction to provide a rotational force, Which is a pumping element for pumping in the direction of the motor, and a suction flow path for sucking water is formed between the motor and the impeller. A pipe or the like for supplying water to the impeller is connected to the impeller side end of the underwater motor pump.

Here, since the underwater motor pump sucks water with a strong suction force for high heading, foreign matter such as sand, leaves and vinyl can be introduced together when water flows through the suction channel. In the wastewater treatment facility, various solid matters and sludge Etc. may be introduced. If foreign substances are introduced through the suction flow path, foreign substances may be caught by the impeller and the operation of the underwater pump may be stopped, or the water discharged from the discharge port of the underwater pump may become turbid and eventually the inside of the water tank may be entirely turbid.

In order to solve such a problem, a strainer as a filtering element is installed on the suction flow passage side so that foreign matter does not flow into the suction flow passage, so that only the water from which the foreign matter is removed can be introduced through the suction flow passage.

On the other hand, the strainer as the filtration element has a cylindrical net body integrally provided on the side of the suction passage of the underwater pump and ring-shaped fastening rings (caps) at both ends of the net in the axial direction, So that they can be fixed to the motor side and the impeller side, respectively. Then, after a certain period of time, foreign substances trapped by the protection filter were removed or the protection filter was replaced. That is, since the conventional protection filter has a cylindrical shape, it is fitted in the axial direction of the submerged pump during tightening and then fastened to the outside of the submerged pump by fastening the bolt through the fastening ring. In releasing the bolt, So that it can be separated.

However, when a protective filter or a strainer is mounted on the suction flow path of the motor pump, foreign matter introduced into the pump is reduced to stably maintain the operation efficiency of the pump and reduce the occurrence of faults due to foreign matter. However, The efficiency of pumping is lowered due to the phenomenon that the foreign matter is adsorbed or fixed to the outer surface of the protection filter or the strainer and the water supply rate is drastically decreased. In addition, there is a problem that the motor pump is fixed when such a state is left for a long time.

In order to solve this problem, conventionally, the protective filter or the strainer has to be replaced or cleaned periodically. In order to solve this problem, the pump must be disassembled and assembled while the operation of the pump is stopped. The protection filter and the strainer have to be replaced and cleaned, so that there is a problem in that maintenance and maintenance are less convenient.

Foreign matter having a predetermined size or more contained in the fluid flowing into the filtration filter 51 is filtered by the filtration filter 51 and adsorbed on the outer surface of the filtration filter 51.

At the same time, as the electric motor 13 rotates, the speed reducer 31 connected to the driving rotation axis s1 of the electric motor 13 rotates, and the speed reducer 31 decelerates the number of revolutions of the electric motor 13 The rotation force of the electric motor 13 is transmitted to the blade 63 via the rotation bracket 41. [

The blade 63 is rotated along the outer surface of the filter 51 by the rotational force of the electric motor 13 and scraped off the foreign matter caught on the outer surface of the filter 51 to be separated from the outer surface of the filter 51 .

On the other hand, a high-pressure cleaning fluid is supplied to the cleaning fluid injection pipe 67 to jet a high-pressure cleaning fluid onto the outer surface of the filtration filter 51 through the nozzle 69 to remove foreign matter adsorbed on the filtration filter 51 .
