Description

RAKE TEETH AND SUPPORT ANGLE WITH GUIDE PLATE OF CARRIER CHAIN CHAIN FOR ROTARY TYPE RAKE}

Features of the present invention are flooded due to heavy rain or rainy season, sewage flooded with waste water, industrial wastes, industrial wastes and agricultural products, etc. are introduced into the drainage pumping station, sewage treatment plant and water intake to remove them. The present invention relates to a rotary damper installed at each waterway entrance.

Conventional Rotary Vibrators

1) Since the horizontal support beam of the BRACKET or the main screen 14 for supporting the main screen 14 is anchored to both sides of the concrete with anchor bolts, it is very difficult to install according to the height work.

2) a problem that the lower frame 13 is vulnerable due to a hole for penetrating the horizontal support beam of the main screen 14 in the lower frame 13

3) Since the main screen 14 and the lower frame 13, which are large structures, are installed in the field, respectively, the equipment performance cannot be 100% due to the accumulation of installation tolerances or the local wear is accelerated to shorten the life of the equipment.

4) Contaminants pass between the lower frame 13 and the concrete surface, and contaminants are caught in the sidebar of the transfer chain 23 and abnormal wear of the transfer sprocket 22 and separation of the chain are caused.

5) Thin impurities such as vinyl remain on the upper guide plates 1 and 2 (11 and 12).

6) In particular, the fact that the guide rails installed on the lower and upper frames 10 and 13 cannot be replaced in case of local welding deformation and wear caused by welding after machining.

There is a problem such as.

The present invention has the advantage of operating the equipment efficiently and reliably by solving the problems of the existing rotary type vibration damper as described above, and 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, and only the details to improve and supplement the existing rotary screen are described.

1. The problem caused by fastening the horizontal support beam (HORI.SUPPORT BEAM) of the main screen 14 with the bracket plate fixed with anchor bolts to the concrete on the side of the channel, that is, the verticality and parallelism of the concrete surface are not constant. Since the length of the horizontal support beam of the main screen 14 is fixed with the lower frame 13 and bolts so that there is no work to modify in the field, all work is performed in the factory to improve the precision of the product, and to carry and install very The lower frame 13 itself improves to a more robust structure since the structure is simpler and also eliminates large holes for penetration of the horizontal support beam of the main screen 14 in the lower frame 13.

2. A rubber plate in front of the lower frame 13 in order to fundamentally block the passage of the contaminants between the lower frame 13 and the concrete on the side of the water channel and to prevent the trapped material from being caught in the side bar of the transfer chain 23. Improved to prevent influx of impurities by installing (RUBBER SHEET)

3. Instead of welding the conveying chain 23 guide rails installed on the lower and upper frames 10 and 13, the servo angle (SUPPORT ANGLE) and the guide plate (GUIDE PLATE) 25 are attached to the upper and lower frames 10, Changed to bolt-tightening structure in 13) to prevent local welding deformation caused by welding of guide rail after machining and improve replacement.

4. When the rake 24 passes through the upper guide plate 1 (11) and the upper guide plate 2 (12), the rake 24 to prevent thin impurities such as vinyl from remaining in the upper guide plates 1,2 (11, 12). ) RUBBER SHEET is assembled at the rear end to lift the upper guide plates 1,2 (11,12) and rubber plate in contact with each other to prevent debris from remaining. Replaceable and improved to reduce costs

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.
