【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. 1, 2 and 3 show an embodiment of the present invention. In this embodiment, 1 is a sedimentation basin in which the traveling siphon-type sludge removing device has been already removed and only the concrete structure remains. This structure is divided into two or more water channels on the left and right by partition walls 2 .... Two of them are shown in FIG. 1, and one of them is shown in FIG.

Explaining one channel, as shown in FIG. 3, a separation band 3 having a mountain-shaped cross section is integrally formed in the center of the width of the channel along the longitudinal direction of the channel. V-shaped grooves 4 and 4 are formed on both left and right sides of the same separation zone 3. As shown in FIG. 2, a V-shaped pit 5 is formed at one end of each of the grooves 4 and 4.

Brackets 6 are newly arranged on both sides of the upper part of the chevron-shaped separating band 3 at intervals along the longitudinal direction, and guide rails 7 extending along the longitudinal direction are provided via these brackets 6. Are paired left and right. The guide rails 7 are arranged in a U-shaped channel material with their backs facing each other. Although only a part is shown in FIG. 1, they are actually provided along the entire length of the separation zone 3.

Reference numeral 10 denotes a traveling body, which is also referred to as a carrier. The traveling body 10 extends in the front-rear direction and has a pair of left and right plate members and a main body 11 that is orthogonally coupled to the upper side of the plate material. And a roller 12 capable of rolling on the guide rail 7. The roller 12 is provided with a flange so as not to come off from the guide rail 7.

A pair of left and right bearings 13 are mounted on the main body 11, and a single rotary shaft 15 is mounted on the bearings 13 via a support shaft 14. As shown in FIG. 3, a support frame 16 that can be tuned and rotated is vertically provided on both left and right sides of the rotary shaft 15, and a scraping member 17 is attached to a lower end of the support frame 16. The scraping member 17 is adapted to fit substantially in the groove 4.

On the other hand, a lever 18 is attached to the upper end of the rotary shaft 15, and a wire rope 19 is connected to the lever 18. As shown in FIG. 2, this wire rope 19 is hung on a pair of sheaves 20 on the left and right sides and a sheave 20 on the pond, and is driven by a drive source on the pond in the leftward direction in FIG. 2 for pulling sludge. Or do a reciprocating motion to the right at a slow speed. The arrow X in FIG. 2 indicates the inflow direction of sewage.

As shown in FIG. 1, this exercise is independently performed for each water channel. Then, the lower end of the sludge discharge pipe 21 faces the pit 5, and the pipe 21 is provided for each water channel. These pipes 21 are upwardly arranged so as to be orthogonal to the longitudinal direction of the water channel. Facing the inside of the distributed gutter 22, sludge is caused to flow with water into the sludge drainage direction indicated by the arrow. The gutter 22 extends vertically above and below the water surface 23.

The operation of the sludge removing device will be described here. When the wire rope 19 is pulled leftward in FIG. 2, the scraping member 17 becomes vertical via the lever 18. This vertical position is defined by the stopper. Then, the scraping member 17 is driven from the left end of FIG. 2 in the conforming posture of FIG. 3 to scrape up the sludge. When the scraping member 17 reaches the stopping member 24 made of packing, it stops at that position. This stop position can be set further forward.

From the time when the sludge is scraped up or from the sludge discharge pipe (pump) 21 that is constantly driven, the sludge is sucked up by water pressure and guided into the sludge ditch through the gutter 22.

On the other hand, when the wire rope 19 is pulled in the opposite direction (to the right in FIG. 2), the approaching member 17 is raised backward via the lever 18 and starts the returning motion. After returning, they move in the opposite direction.

FIG. 4 shows a structure in which the amount of sludge discharged from the sludge discharge pipe 21 protruding into the gutter 22 is controlled so as to increase as the sludge removing device approaches as the sludge removing device moves. is there. That is, below the surface of the water in the pond, a cam shaft 26 is horizontally provided so as to be substantially aligned with the scraping end of the scraping device. The cam shaft 26 is provided with a swing arm 27, and the tip end thereof projects downward. The cam 28 is attached.

One end of a wire rope 29 is connected to the rear end of the swing arm 27, and the wire rope 29 is connected to a control cylinder 31 in the gutter 22 via a sheave 30. The control cylinder 31 has holes 31a ... Which are divided into upper and lower parts, and the upper part of the hole 31a of the control cylinder 31 before the roller 33 at the tip of the column 32 standing upright from the scraping device hits the cam 28. Although the mud is discharged through the roller, when the scraper approaches and the roller 33 pushes up the cam 28 and pulls up the control cylinder 31, the mud is discharged through the upper and lower holes 31a of the cylinder 31.

As a result, the amount of sludge discharged from the sludge discharge pipe 21 due to the water pressure increases, so that the sludge can be discharged with good timing. The scraping device is set to stop when the roller 33 hits the protruding portion of the cam 28.

In FIG. 5, a portion of the long gutter 22 corresponding to each water channel is cut out in a front notch shape to open below the water surface, and horizontal long rotation shafts 35 are arranged in the opening, respectively. A swingable hollow weir 36 is attached above and below. The weir 36 is submerged against its buoyancy, and for driving the weir 36, it comprises a swing arm 27, a cam 28, a roller 33, and a wire rope 29 as a transmission means.

When the approaching device approaches, the roller 33 pushes up the cam 28 and pushes down the weir 36 via the wire rope 29. As a result, the scum on the water surface is attracted into the gutter 22. When the roller 33 comes to the protruding portion of the cam 28, the roller 33 makes a reverse motion, so that the weir 36 floats by the buoyancy of the weir 36 and the restoring force of the cam 28. This will stop attracting scum.

The scum should be moved as close to the weir 36 side as possible. Therefore, not only the roller 33 but a scum plate may be provided. This embodiment is shown in FIG. That is, 38 is a scum plate, which is attached to the upper end of a column 39 standing upright from the traveling body 10 and reciprocates together with the scratching device. In addition, you may comprise the brush 41 which uses the support | pillar 39 and cleans the side surface of the overflow weir 40, and the side wall of a pond.

FIG. 6 and FIG. 7 show another sludge discharge system, in which the sludge discharge pipe 43 is installed transversely in the bottom wall 45 of the pond, and holes are formed in the portions of the pipe 43 corresponding to the respective grooves 4. In addition to being formed, rotary joints 44 for opening and closing the holes are respectively provided. When viewed from the side, the rotary joint 44 is a substantially J-shaped half cylinder, and is normally provided with a protruding portion 44a protruding upward and an opening 44b into which sludge enters.

When the scraping member 17 of the sludge removing device advances in the scraping direction, the projecting portion 44a is tilted and the scraped sludge is sucked into the sludge discharge pipe 43 through the opening 44b. The remaining sludge is discharged through the sludge pipe 21. A sludge discharge pipe 43 may be arranged at the end of the scraping.

As shown in FIG. 6 and FIG. 7, the sludge that corresponds to the end channel of the sludge removing device, sucks the sludge in the groove 4 and guides it upward, and removes it in the sludge groove 47. The pipe 48 may be erected so as to be capable of reciprocating together with the traveling body 10.

In FIG. 9, an auxiliary lever 51 extending upward is attached to the lever 50 of the traveling body 10, and when necessary, the auxiliary lever 51 is extended so that the sludge removing device is lifted above the water surface. May be.

In FIG. 10, the returning end side of the guide rail 53 is a warped rising portion 53a, and the traveling member 10 rides on the warped rising portion 53a, whereby the scraping member 54 removes sludge near the end inclined surface. It is also designed to scratch.
