Description

[Detailed description of the invention] [Industrial application field] The invention relates to a scum processing device.

[Conventional technology]

In a settling pond, many scums accumulate on the surface of the water, and it is necessary to remove them efficiently.

[Problems to be solved by the invention] Therefore, conventionally, a trough called a scum schema is provided, and the scum is caused to flow out by rotating the trough and guiding the scum and water through the inflow port. , If you let it flow out as it is, scum will remain as a lump and it will be difficult to process.

In view of the above circumstances, the problem to be solved by this invention is that
The aim is to make the scum smaller and make it easier to post-process.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a gutter-shaped trough whose longitudinal sides are oriented in opposite directions of side walls partitioning a sedimentation pond.
The troughs are arranged adjacent to each other, and the troughs are connected to each other by a tubular communication trough provided so as to penetrate the side wall, and an opening lower than the water surface is formed on the front side of the trough. In addition to the above-mentioned inflow port, a weir that moves up and down across the surface of the water is provided at the same inflow port. In a scum treatment device in which a seesaw type transmission arm mechanism that is movable and interlocks the weir is arranged, in the communication trough, a strip-shaped plate-like member is formed along the inner circumference of the communication trough. A crushing means having a screw shape in the direction is provided, and the crushing means is formed in a saw-tooth shape.

〔Example〕

Hereinafter, the present invention will be described with reference to the illustrated embodiment.

Before explaining the main part of the scum processing device, the whole structure shown in FIG. 1 will be described. The pond is filled with water and its surface level is 1.

In the pond, flight 3 is driven to rotate by chain 2.
Is provided. 4 is a drive sprocket. The trough 5 is fixedly installed on the water surface 1 of the pond. The trough 5 is a quadrangular cylinder whose upper side is open, and the opening on the front side is an inflow port 6 opened lower than the water surface 1.

As shown in FIG. 2, the trough 5 is formed slightly narrower than the width between the pond side walls 9 and 9, and the inflow port 6 thereof is provided.
A float 7 that can freely move up and down is provided on a support sheet 8 made of rubber or the like so as to move up and down.

On the water surface 1 of the pond, a rotary shaft 10 is installed so as to be in front of the trough 5. A first lever arm 11 and a second lever arm 12 which are transmission arm mechanisms are vertically reciprocally attached to the rotary shaft 10, and the tip of the second lever arm 12 also serves as a weight. A member 13 is attached. A manual arm 14 is provided on the second lever arm 12 in a protruding manner.

By the way, the troughs 5 are connected to each other by a connecting pipe 15. The pipe 15 is a quadrangular cylinder, and is inserted and supported by the side wall 9 to communicate with the trough 5. As shown in FIG. 3, crushing means 16 is provided on the inner peripheral surface of the connecting pipe 15 so as to be screw-shaped in the axial direction. The crushing means 16 is provided with a sawtooth-shaped crushing portion 16a at its tip. In addition, 17 can be adjusted up and down by the diaphragm.

The scum that has flown into the trough 5 together with water is sequentially crushed by the crushing portions 16a while being screwed and is removed. The scum is made finer, which makes subsequent processing very advantageous.

In particular, the weir 7 employs a non-powered scum schemer (or scum removing device) that is pushed down via the transmission arm mechanisms 11, 12, and 13 that are interlocked with the flight 3 in order to drive the weir 7. In addition, the crushing means 16 does not need any dedicated power or transmission mechanism to crush the crushing means 16 by utilizing a natural flow.

Moreover, the scum that has flowed into the trough 5 is agitated with the water that has flowed in so as to be softened by sucking the water, and then subjected to the crushing process by the crushing means 16, so that the crushing action is effectively performed. . Further, after that, it is guided to the adjacent trough 5, but also there, it is crushed by the next crushing means 16 while being softened by being agitated by the water flowing into the trough 5. In this way, by repeating softening and crushing, it becomes a fine scum naturally.

Although the following is a proposed example, as shown in FIG. 4, the crushing means may be constituted by a sharp pin 20. Also, the fifth
As shown in the figure, the thin plate 21 may be bent.

As shown in FIG. 6, a hole 27 is provided in a wall 26 on the trough 5 side of an outflow passage 25 provided at the back of the trough 5, and a through hole 28 is provided so as to correspond to the hole 27 of the trough 5, Moreover, a fixed or rotary crushing means 29 may be provided in the hole 27. As the crushing means 29, those of each of the above examples can be adopted.

Incidentally, as shown in FIGS. 7 and 8, the dam member
It is also possible to make 35 movable up and down and to equip the upper end with the float 36.

Moreover, FIG. 9 and FIG. 10 show other proposal examples. In this example, the power of a scum removing conveyor (raising net type) 41 arranged so as to scrape up the scum at the end position of the trough 40 is used, and water collected at the end is returned to the water return conveyor 42.
It may be configured to return to the pond. The scum from the scum removing conveyor 41 is put in a scum container 43 on the pond, and water is returned from the water returning conveyor 42 to the pond through a drain gutter 44. As a result, the water is separated from the scum as compared with the case where the water is removed together with the scum, so that the subsequent treatment is facilitated.

[Effect of device]

As described above, according to the present invention, the scum can be made fine to facilitate post-processing.

In particular, the scum can be swallowed and crushed effectively without requiring any dedicated weir drive source or drive source for the crushing means.
