Abstract

The present invention is installed at the water inlet of drainage pumping station, water intake and sewage treatment plant, flooded roads due to heavy rains and rainy seasons, and overflowed sewers, so that many living wastes, industrial wastes and agricultural products are flooded or floated in water. It is introduced into the intake and sewage treatment plants. In general, pump stations, intake stations, and sewage treatment plants are installed by removing tanks, fine screens, and vibration dampers at the inlet of waterways to remove contaminants entering with water. Rotary type vibration dampers can be installed in each channel to remove impurities. As a vibration damper facility, the performance of each part is improved and supplemented to make it more efficient and safer to operate.

According to the present invention, the pair of left and right lower frames 13 installed inclined at the inlet of the waterway is fixed by anchor bolts at the upper part of the concrete structure so as not to move, and the main screen 14 is fixed in the lower frame 13 by bolts or welding. In addition, the lower front screen 15 is assembled by connecting pin bolts (PIN BOLT) at the same space as the flat screen of the main screen 14 at the lower front of the main screen 14.

The upper frame 10 is bolted to the lower frame 13, and installs the upper guide plate 1 (11) and the upper guide plate 2 (12) to guide the contaminants safely to the conveyor 26, in particular the upper guide plate 2 (12). Is a structure that can move as much as the distance moved by the adjustment of the SCREW of the conveying chain tension adjusting device 21, the drive shaft, drive sprocket (16) on the output shaft of the motor installed in the upper structure (DECK STRUCTURE) (27) 18) and the shear pin hub 19 are assembled, and the upper shaft 17 is assembled with the conveying sprocket 22, the conveying chain 23, the conveying chain tension adjusting device 21, and the bearing. In addition, the upper and lower frames 10 and 13 are provided with guide rails 25 to prevent sagging and detachment of the transfer chain 23.

The transfer chain 23 is provided with rakes 24 having a rake at regular intervals, while lifting by the power of the motor 16 to lift the contaminants in the upper portion and conveyed to the contaminant container by the belt conveyor 26. Allow export.

Description

DRIVE, DRIVEN CARRIER SPROCKET OF ROTARY TYPE RAKE}

Features of the present invention are flooded due to heavy rain or rainy season, flooded sewers flooded with water, and other wastes such as household waste, industrial waste, and agricultural products flow into drainage pumping stations, sewage treatment plants, and intake stations to remove them. The rotary type vibration damper installed in each channel has a conventional rotary type vibration damper

1) The shear pins are not sheared or the shear surface is not uniformly sheared by using general pins to secure the safety of the equipment.

2) The lubricating oil is injected to reduce the friction between the driving sprocket and the sewer pin hub.

3) The use of "S" teeth for driving and driven sprockets results in high wear on the teeth.

4) In particular, the toothed part of the conveying sprocket is accompanied with problems such as abnormal wear caused by the impurities.

The present invention solves the problems of the existing rotary type vibration damper as described above, there is an advantage that can be efficient and stable operation, the accompanying drawings and the conceptual features for achieving the above object of the present invention. Let's look at it together.

The basic driving principle and structure of the rotary vibration damper is described above only in the details to improve and supplement the existing rotary screen.

1. The transfer sprocket 22 is a casting type, and all the tension is transmitted from the tooth part to the "S" tooth, which causes a lot of wear on the tooth part and replaces the entire transfer sprocket 22 due to severe wear and economic loss. Considering that it takes a long time to pay

1) Changed to welding type with short production period

2) The tooth part is guided only for rotation and transfers tension by the contact with the friction plate of the side bar of the conveying chain 23 and the conveying sprocket 22, so that it can be changed to a structure capable of transmitting high tensile force.

3) Tooth part complements tooth insert (TOOTH INSERT) for replacement

4) Improved corrosion resistance by using stainless steel (STS 304) instead of cast steel in consideration of moisture but not in contact with water.

3. OILNESS BEARING on the pin hub 19 instead of the structure to prevent corrosion and rust on the inner surface of the pin pin hub 19 assembled to the drive sprocket 18 and to inject lubricating oil for smooth driving. ) It is free from the hassle of lubricating oil, the surrounding is clean, and the maintenance is convenient.

4. Improved to extend machine life by applying "C" CLASS teeth that minimize wear, instead of drive and driven sprockets (18,20) which are generally "S" teeth.

By improving and supplementing the existing rotary vibration damper as described above, it is possible to prolong the life of the device and to minimize the operation and maintenance more efficiently.
