Description

Moving screen device {Apparatus for moving screens}

The present invention is equipped with various pump stations, such as intake, drainage, relay pumping station, and various screens such as sewage, sewage, and wastewater treatment plants, and separates the various floats and contaminants contained in the influent flowing into the treatment plant by the flow rate when the inflow passes. Moving screen device for removing by moving to the upper part of the box, particularly in the chain link plate of the continuously-tracking hoisting-type lifting chain each of the box-type screen is attached to the screen by the flow rate when the inflow In addition, the present invention relates to a moving screen device which continuously removes the contaminants to the upper portion of the channel by driving a driving motor connected to the lifting chain to filter the contaminants filtered by the screen.

In general, as the industry develops, various inflows of impurities, impurities, suspended solids, and contaminants of different sizes and types are introduced into the influent of various pumping stations and various treatment plants. In particular, during heavy rains and floods, various contaminants floated with rainwater flow into the intakes of the intake pumping stations and the reservoirs of the drainage pumping stations. In this way, if the contaminants mixed with the inflow water are not removed quickly, the water channel is flooded, causing various problems such as clogging of the pump at various pump stations. Therefore, in the past, it was common to provide a grid-like screen in order to reliably separate such contaminants from the influent. After the screen is installed and the impurities are separated from the influent, the separated impurities are quickly removed from the screen so that the efficiency of the screen can be expected. However, if the debris separated by the screen is not left for a long time or is not quickly removed, the filtered debris may stick to the screen and cause the screen to be clogged, which may disturb the flow of water in the channel and cause the channel to overflow. In order to prevent this, a person removes or uses a tool. Manual man-powered removal, which removes man directly from the screen, checks the amount of contaminants caught on the screen from time to time, while eliminating manpower when the channel is wide and deep. In addition, the use of tools to remove debris is usually a method of picking up a debris on the screen with a rake. This can be done by breaking the screen or removing the device during rake removal if the material is heavy or heavy. It damages the driving motor and various driving parts used in the system. In other words, light debris hangs on the top of the screen, making it easy to remove, but heavy debris hangs on the bottom of the screen, requiring underwater work, which is very difficult to remove.

Conventionally, in order to separate such contaminants from the influent, the driven driven sprocket 12 mounted on the rotating shaft of the driving motor 10 generating power as shown in FIG. 1 is driven driven mounted on the lifting spindle 62. The drive chain 14 is hooked to the sprocket 63 to transfer power to the lifting driven sprocket 64 inside the body. This lifting main shaft 62 is provided with the take-up member 80 for adjusting the length of a chain. The lifting driven sprocket 64 and the lifting driven sprocket 66 mounted in plural to the lifting driven shaft 68 rotate by lifting the lifting chain 60 in parallel to both sides. Between the parallel lifting chains 60, a rake 50 that rotates in one round is removed at predetermined intervals in order to remove impurities. In addition, a plurality of fixed screen bars 40 formed at predetermined intervals are installed between both sidewalls of the contaminant removal device through which the inflow water passes, and the rake 50 is fixed between the plurality of fixed screen bars 40 while passing through them. It is to remove the clutter caught in the screen bar 40. Removed impurities are stored in the contaminant box 70 provided on the rear side of the contaminant removal device and then removed.

Such a debris removal device is equipped with a plurality of fixed screen bar 40 formed at a predetermined interval between the both side walls of the inlet flows into the inlet, the rake 50 mounted between the lifting chain 60 is fixed screen While passing between the bars 40, and removes the impurities caught in the fixed screen bar 40 continuously.

Therefore, the conventional contaminant removal device removes the contaminants caught in the fixed screen bar 40 by transferring the rake 50, so the size of the contaminants can only be determined by the distance between the rake 50 and the fixed screen bar 40. Since it is impossible to remove large contaminants, the rake 50 and the fixed screen bar 40, the trouble caused by the trouble frequently. Therefore, such large contaminants were inconvenient to be removed by manpower, and because of the use of people, not only the risk of safety accidents, but also the waste of manpower and maintenance were very difficult. In addition, since it is difficult to adjust the size, shape, and spacing of the screen bar according to the size of the contaminants, it is almost impossible to remove small contaminants, resulting in water pollution.

The present invention for solving the above problems is equipped with a box-type bar screen for each of the links of the lifting chain to rotate around to remove the contaminants contained in the intake water flowing into the intake pumping station, drainage pumping station and various wastewater treatment plants, Contaminants contained in the air are caught on the surface of the screen by the flow rate, and the screen is transported out of the surface, and the caught impurities are removed by spraying the washing water from the rear part of the screen when the screen is rotated / moved into the shape inverted by the main shaft. , In front of the brush to remove. Therefore, in the present invention, compared to a device that removes contaminants by operating a separate removal device such as a rake to remove the contaminants caught on the fixed screen of the prior art, the screen is removed without a separate rake device to remove the contaminants. It is not limited in size, it is difficult to remove contaminants, and the work process that has been removed by manpower can be automated and unmanned to simplify the work process and increase efficiency. In addition, by adjusting the size, shape and spacing of the screen bar according to the size of the contaminants, even small contaminants can be removed, which has the advantage of preventing water pollution.
