Abstract

PURPOSE:To obtain a running type precipitated sand scrape-up apparatus wherein the traversing conveyor of a conventional running type precipitated sand scrape-up machine is dispensed with and the scrape-up apparatus is placed on a precipitated sand accumulation layer and enabled in inspection at a part above water while power consumption is reduced and handling is made simple. CONSTITUTION:A saddle having wheels arranged to both ends thereof is placed on rails 15 and a girder 2 is arranged to the saddle so as to straddle a sand precipitation basin 1 while a vertical frame 9, a lift apparatus 13, a chute 18 and a casing 20 supporting a chain wheel 3 are provided to the single side of the girder 2 and sheave wheels 11 are provided to both sides of the girder 2. A transverse frame 8 is provided to the sand precipitation basin 1 under the girder 2. Then, tensioning of a chain by the rising and falling of vertical and transverse frames 9, 8 is performed by the tensioning chain wheel 4 provided to the frame 9. The chain 7 provided with buckets is mounted over the chain wheel 3, the tensioning chain wheel 4 and underwater chain wheels 5 and moved by a drive apparatus 14.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a sand hoist 1 used in a sand settling basin in a sewage treatment plant, etc.
M, a bucket collector and device for raking and raking sand in one ttc, and a packet collector device for raking sand from multiple ponds, and a traveling device for moving it to other ponds.

This invention relates to a traveling type sand-settling device with a lifting device.

A conventional traveling sand scraping device that has been put into practical use is a packet elevator that is equipped with chain wheels at both ends of a vertical frame that extends between the inside and the top of the pond. A device, a traversing device to move the device along the entire length of the pond and level the sand, a lifting device to raise and lower the vertical frame to scrape up sand from multiple ponds, and a traveling device to move the vertical frame to another pond. Fried sand-
There is one that consists of a conveyor for collecting sVc.

This traveling type sand settling and scraping device requires a baffle lifter device, a traversing device, a lifting device, a traveling device, a conveyor, and a drive device to move each machine, which requires a lot of effort.

It had the disadvantage of requiring strength.

Furthermore, since there are many machines, the control device is complicated and it is difficult to handle each machine.

One object of the present invention is to provide a traveling type sand settling and scraping device that improves the drawbacks of conventional traveling type sand scraping machines, consumes less power, and is easy to store and handle.

The present invention is characterized by the following points.

1) Contrary to the conventional traveling type sand settling and scraping machine, there is no traversing conveyor, so there is less power consumption (02) It is possible to scrape up sand from multiple ponds, using only a traversing device, a traveling device, a packet collector device, and a lifting device. I can do it.

6) Since the raking device is located above the sediment pile, there is no need to bury the sediment in the sand basin.

4) Maintenance is easy because the lifting device can be inspected above the water.

5) Self-driving is possible.

The present invention will be explained based on the drawings.

In Figs. 1 and 2, reference numeral 1 denotes a plurality of sand settling basins having desired lengths, depths and widths, and the rails 15 are laid on both ends of the sand rails, which are opposite to each other at right angles to the settling basin waterway. 1 places a saddle 16 with wheels 19 installed on both ends, and a saddle 16Vc
Two garters will be placed in the same way as a settling pond. Gata 2
On one side are the shrimp frame 9, the lifting device 13, and the chute 1B.
A casing 20 for supporting the chain wheel 5 is also provided. Note that the vertical frame 9 is supported by the casing 20 so as to be movable up and down.

Furthermore, sheave wheels 11 are provided on both sides of the gutter 2.

A horizontal frame 8 is installed in the settling basin below the cark 2, and the horizontal frame 8 can be raised and lowered to the upper position of the settling basin, and the submersible chain wheel 5? A kite rail 21 is disposed at both ends of the horizontal frame 8 so as to be rotatably supported, and a kite rail 21 is disposed between them so that a chain 6 equipped with a packet 7 to be wrapped around an underwater chain wheel 5 can be moved horizontally.

The horizontal frame 80 is rotatably connected to the vertical frame 9, and 10 lobes are attached to one end of the horizontal frame 80, which are wrapped around the sheave wheels 11 provided at both ends of the garter 2, and connected to the upper VC of the vertical frame 9. As the vertical frame 9 is mounted and moved, the horizontal frame 8 is made to be horizontal.

The vertical frame 9 has a lifting device 1! + is provided to drive the lift.

The tensioning of the cheno 6 by raising and lowering the vertical and horizontal frames 9.8 is performed by the tension chain wheel 4 provided with the vertical frame 9Vc. Incidentally, the tension chain wheel 4 is attached to the upper part of the vertical frame 9, and the underwater chain wheel 5 is attached to the lower part.

A chain wheel 7 equipped with a packet 6 is wound around the chain wheel 3, tension chain wheel 4, and underwater chain wheel 5, and these are moved by a drive device 14.

The conveyor 17 transports the packets 7 through a chute 18.

Claims (1)

[Claims] Multiple chain wheels are installed on the gutter that runs across the sand basin, and chain wheels are installed on the lifting frame that can raise and lower the part that scrapes up the sediment from the pond bottom, and these chains are simply wrapped around a chain with a packet endlessly. In a sand scraper that transports sand from the basin to an electric lift, a chain wheel is installed on the vertical frame connected by a bottle joint at one end of the lifting frame installed in the sand basin.
As the vertical frame moves, the chain is tensioned. A rope is installed at the other end of the lifting frame, and the rope is attached to the vertical frame via a gutter (provided with a sheave) and a drum. A traveling type sand raking device characterized in that it is equipped with a TV and sequentially scrapes up sediment from the upper surface of the sediment together with a plurality of settling ponds.
