Abstract

PURPOSE:To automatically deliver foreign matters arrested from below to upper part by a method in which rotary foreign matters receiving and delivery plates are attached vertically multi-stepwise to a framework provided in waterway, and the plates are rotationally moved properly and alternately. CONSTITUTION:When foreign matters 16 are gathered on foreign matters receiving and deliver plates 5 whose end side is highly inclined, rotary shafts 4 positioned upwardly one shaft apart from that next to the lowest stage are clockwise turned through 90 deg. to turn the plates 5, whereby foreign matters 16 gathered on the lower adjacent plates 5 are scooped up and received. Then, the rotary shafts 4 positioned upwardly one shaft apart from that 4 of the lowest stage are turned clockwise through 45 deg. and the plates 5 are erected and stopped. Then, the rotary shafts 4 positioned upwardly one shaft apart from that 4 next to the lowest stage are clockwise turned through 45 deg. and the plates 5 are stopped at the place where the side before the water flowing side is highly inclined. These are orderly repeated and thereby foreign matters 16 are orderly discharged through a chute 14 and a conveyer 15 from the delivery plate 5 at the uppermost stage.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust remover that captures foreign matter such as dust flowing with water in sewers and discharges it to the outside of the machine.

Conventionally, as the above-mentioned dust remover, a screen is installed in waterways such as sewers, and the dust captured by this screen is removed.
A rake attached to a continuous chain that can be raised and lowered is generally used to raise and discharge the waste outside the machine.

but.

Conventional dust removers have the disadvantage that large contaminants cannot be removed with a rake, and the screen often gets clogged.

In this invention, a large number of contaminant receiving/conveying plates are fixed to rotating shafts installed in multiple stages above and below a frame body, and the contaminant receiving/conveying plates are rotated alternately as the rotating shaft rotates. The contaminants captured by these are transferred from the lower part of the contaminant receiving/conveying plate to the upper part, and then discharged outside the machine, thus solving the deficiencies of the conventional method described above. do.

It is an object of the present invention to provide a divider that can reliably remove even large foreign objects and is less likely to be clogged.

An embodiment of the present invention will be described below with reference to the drawings.

In Figures 1 and 2, 1 is a sewer waterway through which sewage flows, 2 is a nine-frame body inserted over the entire width of this waterway 1, and this frame 2 is located in the direction of the arrow in Figure 2. 1. Projecting above the water surface of the waterway 1, it slopes rearward and upward with respect to the water flow direction shown. It is fixed to a pedestal 7. Rotating shafts 4 are installed horizontally on the frame 2 in multiple stages, upper and lower, and a large number of dirt receiving/conveying plates 5 are fitted and fixed to each of these rotating shafts 4 at narrow intervals in a comb pattern. There is.

The debris receiving/conveying plate 5 is made of a hook or a hard synthetic resin plate, and has an S-shape, with the rotation axis 4 at the center.
The dirt receiving/conveying plates 5 of the vertically adjacent rotating shafts 4 are arranged so as to alternate in the axial direction of the rotating shaft 4. The driving means 6 for rotating the foreign object receiving/conveying plate 5 has left and right driving sprockets 9 to which driving force is transmitted from an electric motor 8 fixed to a pedestal 7 fixed above the waterway 1, The upper ends of left and right operating rods 12 are connected to crank arms 11 that are fitted and fixed to these sprockets 9 and shafts 10, respectively. One ψj1 part of the rotating shaft 4 is connected to the other operating rod 12 via a link 13, and the other end of the rotating shaft 4 on the upper stage side is linked to the other operating rod 12 from the next rotating shaft 4 on the lowermost stage to every other one. They are connected via 13. Behind the contaminant receiving/conveying plate 5 provided on the rotary shaft 4 of the lowest stage, there are four upper discharge chutes 14 stacked one on top of the other, and below the second chute 14 there is a conveyor for discharging contaminants. 15 are arranged.

Next, the dust removal-like operation configured as described above will be explained. As shown in FIG. 3(a), the contaminant receiving/conveying plate 5, which is positioned upwardly from every other hanging stage and tray, is tilted high in the direction of water flow, and contaminants adjacent to above these contaminants are At the position where the material-conveying board 5 is upright, each foreign material receiving and transporting board 5 stops and collects the foreign material 16 such as dust flowing with the running water into the foreign material whose front side @ 11 is tilted high. It is captured and stored on the receiving and conveying plate 5. When a certain amount of foreign matter has accumulated, the rotating shafts 4 are positioned upward every other time from the next rotating shaft at the lowest stage as shown in FIG. 3(b). Rotate 90 degrees clockwise as shown in the image below
By rotating the receiving container conveyor 5, the contaminants 16 accumulated in the contaminant receiving and conveying g5 adjacent below these are scooped up, received, and stopped. Next, as shown in FIG. 3(c), the rotating shafts 4 located above every other rotating shaft 4 in the lower reed are rotated 45° clockwise, and the 1. 'iF 5 stands up and stops. Further, as shown in FIG. 3(d), every other rotation shaft 4 is located above the next rotation shaft 4 in the lower stage.
are rotated clockwise by 45°, and the foreign matter receiving and conveying plate 5 provided thereon is stopped at a position where the front side in the direction of water flow is highly inclined. Further, from the state shown in FIG. 3(d) to the state shown in FIG. 3(a),
) by rotating the rotating shaft 4 in 2HJ divisions and repeating the above-mentioned operation, the foreign matter 16 captured by the foreign matter receiving/conveying plate 5 of each stage is sequentially transferred to the upper stage one by one. Contaminant receiving/conveying: The contaminants are delivered to f5 and conveyed, and the contaminants are dropped from the top contaminant/conveying plate 5 through the discharge shoe 14 onto the conveyor 15 for carrying out, and this conveyor 15 collects the foreign contaminants outside the dust remover. Discharge in place. The rotating shaft 4 is rotated by driving the weight 8 of the driving means 6 to rotate the moving sprocket 9, and rotate the rotating shaft 4 through the crank arm 11 and the operating rod 12 to rotate d+114 and a plurality of foreign material/carrying plates 5. The rotating shaft 4 and the container/transfer plate 5 are divided into two strings and alternately rotated intermittently by an appropriate means such as a timer (not shown). shall be taken as a thing.

In addition, in this invention, the five foreign material transport plates may be rotated continuously without being rotated intermittently, and the shape of the foreign material carrier/transfer w5 and the structure and operation of the driving means 6 are as follows. The present invention is not necessarily limited to the embodiments described above, as long as the contaminants can be sequentially delivered and conveyed from the bottom to the top by the rotation of the contaminant receiving/conveying plate accompanying the rotation of the rotary shaft.

As explained above, the dust remover of the present invention eliminates the conventional rake and uses a large number of contaminant receiving and conveying plates fixed to the rotating shaft to capture contaminants contained in sewage, etc. Since the debris is conveyed from the bottom to the top according to the word of mouth of the debris receiving/transfer plate, even large debris can be reliably discharged from the machine, and the debris receiving/transfer plate has a rotational speed of Because the screen moves, it is less prone to clogging than conventional fixed screens.
