Description

[0001] The present invention relates to a rotary type dust removing machine,

The present invention relates to a water treatment system that is installed in an open channel of a low-lying drainage pumping station, a water supply water intake pipe, a related water supply channel, a sewage treatment plant and a dam, And more particularly to a rotary damper device having a cleaning means capable of removing contaminants circulating between rakes without being discharged to the outside.

Recently, water intake and drainage capacities have been increasing due to the enlargement of various water intake and drainage pumping stations, and sewage and stormwater pumping stations have been installed in many places depending on the progress of sewerage supply. In these water treatment plants, If there is contamination of dirt and garbage, so-called various impurities, the pump will be broken or the pumping function will be considerably weakened, and these trash will block the water channel, It involves several problems.

For this reason, the flow of the water flow is made smooth by arranging the dust collector on the water line so that the impurities which flow into the drainage channel together with the water flow can not flow to the pump side.

As shown in Fig. 1, there is a "front elevating type rotary damper" disclosed in Korean Utility Model Registration No. 325084, which is installed in the middle of a drainage passage to automatically filter out contaminants and discharge the damages to the outside. The operation relationship is as follows.

The rotary damper according to the present invention includes a screen 200 and a disposable screen 201 integrally mounted on the upper surface of the main body 100 so as to be inclined with respect to the upper surface of the main body 100 and a rake 300 are mounted on a chain 401 and a driving unit 400 for driving the chain 401 is installed on the main body 100. The main body 100 is provided with a cover 401, A rotary shaft 600 is rotatably mounted on a support 601 for rotating the main body 100 and a wire rope 701 connected to the main body 100 is connected to a motor 702 So that the main body 100 is lifted up.

When the motor 300 is driven, the rake 300 rises along the chain 401, and the obstacles filtered by the screens 200 and 201 are lifted up. The rake 300 is turned at the top of the rake 300 and is rotated and dropped down to be discharged. At this time, the discharged contaminants are conveyed to the outside by the conveying conveyor C to be removed.

The reason why the wire rope 701 is pulled up by driving the motor 702 through the above-described invention to raise the damper main body 100 is that when the damper is installed in the water channel and is not in operation, If there is a problem, the lower part of the damper can easily be corroded by water. Also, when there is a problem that the screen and the chain are clogged with the damper, it is necessary to close the water of the channel and replace the damper The damper main body 100 can be exposed to the outside of the water for the purpose of avoiding the problem.

However, all conventional arrangements, including the above-mentioned damper device, have shown that when the rake 300 lifts up the contaminants during the ascending movement, the chain 401 is moved to the upper sprocket wheel (the upper sprocket wheel is located at 401 in FIG. 1) When the rake 300 is turned upside down due to the change of the moving direction, the scraped contaminants fall down freely and fall on the conveyance conveyor C, and the dropped contaminants are moved to the collecting place on the conveyance conveyer C, It is designed to be disposed of, and the scum removed from the waterway contains grass, rope or various vinyls that have been washed away from the mountains or the like. In case of these vinyls or grasses, when the lake 300 is turned, And is caught in the clearance with the screen member while running while sticking to the rake 300, thereby inducing an overload to the motor, If the damper is damaged, the damper device is stopped or the wedge action is interposed between the frictional contact members to cause the device to be horizontally balanced, thereby stopping the operation of the device, causing flooding due to loss of the drainage function during the flood season, There has been a problem that frequent occurrence of cost and time for maintenance work has occurred.
