[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the invention according to claim 1 is a tank-type scum / water separator for separating scum from sewage containing scum by a floating action and discharging it to the outside of the device. Insert the scum water introduction pipe so that the scum water discharge port at one end faces downward and faces the inside of the same tank, and inside the main body tank, a buffering device is arranged opposite to the outlet of the scum water discharge port. The separated water can be discharged to the outside through the lower part of the main body tank. According to the second aspect of the present invention, the drive shaft is passed through the scum water introducing pipe, and at the lower end of the drive shaft, scum removing means such as a brush for removing scum on the surface of the buffer means is attached. In addition, around the outer periphery of the scum water introduction pipe, there is provided a blade that rotates the scum accumulated in the main body tank in conjunction with the drive shaft and sends the scum to the discharge port of the main body tank. According to the third aspect of the invention, the vanes are mounted around the drive shaft so that the flow of scum water serves as the rotational force of the drive shaft. According to a fourth aspect of the invention, the buffer means is made of a sponge-like material. According to a fifth aspect of the present invention, the lower portion of the main body tank is downwardly constricted, and the water separated from the lower portion is discharged. The invention according to claim 6 is a tank-type scum / water separator that separates scum from sewage containing scum by a floating action and discharges it out of the device. It is inserted to face the inside of the tank with the scum water discharge port at one end facing downward, and inside the main body tank, a buffer means is arranged opposite to the outlet of the scum water discharge port and separated. The water is configured to be discharged to the outside through the lower part of the main body tank, and a weir is provided in the main body tank for collecting the floating scum into the trough by the floating and sinking operation.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. 1 and 2 show an embodiment of the present invention. Reference numeral 1 is a main body tank, and the main body tank 1 is a cylindrical body with its center oriented vertically, and the top and bottom are sealed by a top lid 2 and a bottom lid 3. A pedestal 4 made of a channel material is provided on the bottom of the bottom cover 3.

Reference numeral 7 denotes an L-shaped scum water introducing pipe, in which scum water is guided through a horizontal portion outside the pipe 7, and a vertical portion of the pipe 7 is passed through the upper lid 2 to a main body tank. The center of 1 is provided downward. The scum water introducing pipe 7 has a trumpet shape at the lower end to serve as a scum water discharge port 8. The discharge port 8 is located in the middle of the upper and lower sides of the main body tank 1, and the scum water flows downward through the discharge port 8. It is supposed to be released vigorously toward.

A drive shaft 10 is rotatably attached from the upper end of the scum water introduction pipe 7 to the discharge port 8, and a biasing blade 11 is attached to the outer periphery of the drive shaft 10 in a screw shape. ing. The blade 11 rotationally drives the drive shaft 10.

Reference numeral 12 denotes a brush, which is horizontally attached to the lower end of the drive shaft 10, and blades 14 and 14 for scum suction are attached to the upper end of a stay 13 extending upward from the brush 12. As shown in FIG. 2, the blade 14 has a shape that is curved in one direction when viewed from above.

Immediately below the scum water discharge port 8, a pedestal 16 is horizontally provided by a support member 15, and a sponge (buffer means) 17 is horizontally provided on the pedestal 16. The sponge 17 has an uneven upper surface, and functions to absorb the falling energy of the falling scum water and to flow it in the outer diameter direction.

The surface of the sponge 17 is rubbed by the brush 12 to scrape and collect the scum. 20 is a discharge port for discharging the floating scum 21. A discharge mechanism 23 having a screw 22 communicates with the discharge port 20, and communicates with a chute 24.

A sponge diaphragm 25 is attached to the inner peripheral surface of the intermediate height of the main body tank 1, and at a lower level, only the scum is adsorbed and removed from the water containing the floating scum. In order to do so, many scum adsorbents 26 ... Are hanging down.

A water outlet 29 is opened at the bottom corner of the main body tank 1 through a mesh 28, and water from the outlet 29 is guided to a drain 30 through an inverted U-shaped route. It has become so. The weir 31 is a weir that can be adjusted up and down, and the height of the skim can be controlled by the adjustment. Further, the drive shaft 10 may be driven by a motor.

FIG. 3 shows another embodiment. In this embodiment, the main body tank 35 has a constricted lower portion, a scum removing net 36 is arranged in a transverse shape inside the main body tank 35, and a drain pipe 37 is connected to the lower end of the main body tank 35 to communicate with the outside through a valve 38. I am allowed. The scum removing net 36 may be configured so that it can be backwashed as indicated by an arrow so that the scum can be removed periodically.

FIG. 4 shows another embodiment. In this embodiment, a part of the brush mounting member 40 is extended in the outer diameter direction to form a cam 41, and the scum recovery device 42 is driven by the cam 41. The scum recovery device 42 is provided with a horizontal rotation shaft 43 at the front part of the trough 44, and the rotation shaft 43 allows the weir 45 having an oval shape and a hollow cross section to vertically rock.

The weir 45 can be returned upward by a spring 46, and the weir 45 is pulled down like an imaginary line when the cam 41 hits the roller 48 of the arm 47. The weir 45 descends below the surface of the water so that the scum can enter. When the cam 41 passes by, the weir 45 returns upward by the spring 46. This return is also made by the hollow buoyancy of the weir 45. The scum is discharged to the outside through the scum pipe 49.

In FIG. 1, scum water from the scum water introduction pipe 7 is discharged from the discharge port 8 while rotating the blade 11. Here, the scum water is decelerated by being buffered by the sponge 17, and the sponge and water are effectively separated. The scum 21 floats, is scraped up to the discharge port 20 by the blades 14, and is discharged to the outside by the screw 22.

On the other hand, the separated water flows downward, but scum may also be mixed in it. These scums are adsorbed by the scum adsorbent 26 and float up. The water is further separated from the water by the mesh 28 and then discharged from the water outlet 29. The sponge may be replaced by a large number of upward protrusions.
