Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scum removing device. [0002] In equipment for purifying water, for example, in the first or final settling basin, a large amount of scum stays in a floating state on the water surface, but these scums are unnecessary. The scum is removed from the pond by a scum remover. In the past, scum was removed manually or electrically by a rotary trough, but this operation was difficult, costly, and scum could be effectively eliminated. could not. The Applicant has developed an automated device that performs this removal in relation to the movement of the flight in the pond. this
The device consists of trough, weir, transmission mechanism with cam, etc.
Is done. The trough is partially fixed and installed in the treatment pond so that the opening is lower than the water surface of the treatment pond. The weir is a hollow float, and is provided at a front position on the opening side of the trough so as to be able to protrude and descend at the water surface.
The transmission mechanism consists of a swing arm with a cam at the tip and a swing arm.
It is composed of a mechanism for causing the weir to respond to the dam. cam
Is to follow the flight circulating in the treatment pond
It is kicked up more and the swing arm receives it directly and swings
Then, this movement is transmitted to the mechanism for responding and pushes the weir.
I try to lower it. When the weir sinks below the surface of the water,
The scum flows into the trough with the water
Is removed outside the pond through the trough . The swing arm is lowered when the flight passes over the position of the cam, in this
Then, the weir floats and returns to the surface of the water, and the scum is stopped. [0003] By the way, this scum
The following problems have been encountered with the removing device. That is, before

It is characterized in that it also serves as a support for the moving means . Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. 1 to 3
1 shows an embodiment of the present invention. In this embodiment, the sedimentation basin (treatment pond) has a rectangular shape whose plane shape is long in one direction, and is generally called a rectangular sedimentation basin. The sedimentation basin is located in the first-floor tank 1, in which a scum removing device A is installed. A water surface 3 is set in the first floor tank 1, and a chain 5 having a plurality of flights 4 # arranged below the water surface 3 is provided so as to be driven in the direction of the arrow. One or two (and more if necessary) of the flights 4 are provided with a roller type attacker 7 via a roller bracket 6 so as to protrude upward. This attacker 7
Are located closer to the inside of the guide rail 8. Numeral 9 is a trough-shaped trough, which is formed by a part of a cylinder as shown in FIG. 3 and is fixedly installed over the entire width of the pond. The upper portion of both ends in the circumferential direction of the trough 9 is an inlet. Both ends of the trough 9 in the longitudinal direction are the side walls 1 of the pond.
The scum attracted into the trough 9 is connected to pipes fixedly penetrating through the pipes 1 and 11, respectively, and is guided to the outside through these pipes. 10,10
Is a belt-shaped guide member formed of a rubber plate attached to the upstream side and the downstream side of the trough 9. Both ends of the guide 10 have troughs provided at both ends of the trough 9 at right angles to the trough 9 at right angles. 9 are sealed by side seal rubbers 12, 12 protruding from 9. The side seal rubber 12 includes a portion formed in a curved plate shape when viewed from above, and the portion is a flexible portion. The guide 10 is attached to the front and rear edges of the trough 9 with one side as a base, and the other side is protruded forward and upward from the trough 9 as a tip. The angle is about 35 degrees with respect to the water surface. The weir 13 is positioned forward through the tip of the guide 10.
Is attached. The weir 13 is made of stainless steel having a hollow shape and an upper part having a mountain-shaped cross section. The front part of the upper part is inclined forward and downward, but the rear part of the upper part is also inclined backward and continuous with the surface of the guide 10. Inclined surface (approximately 35
Degree). 14 is a cable end connection pipe,
It is attached to weirs 13,13. On the other hand, a swing arm 15 is attached to the side wall 11 of the first floor tank 1 so as to be upstream of the trough 9 and above and below the chain 5. A cam mounting arm portion 15a, which is one end of the swing arm 15, extends toward the upstream side, and a pressing arm portion 15b, which is the other arm, extends toward the downstream side.
The cam mounting arm 15a is located closer to the inside of the pond than the side wall 11, and the pressing arm 15b is located closer to the side wall 11 than the cam mounting arm 15a. The arms 15a and 15b are eccentrically arranged. . A cam 19 is mounted on the cam mounting arm 15a via a long hole 18 # with a bolt so as to be vertically adjustable. Further, as shown in FIG. 2, the cam mounting arm portion 15a
A cam mounting portion h on which the cam 19 is mounted and a skewed portion s which rises obliquely upward from the portion h toward the base boss 32. A support bracket 16 protrudes from one side wall 11, and a rotating cylinder 17 is fixed on the bracket 16 in parallel with the longitudinal direction of the weir 13, and an inner end of an arm shaft 33 passed through the rotating cylinder 17. The boss 32 is attached to the portion, and the pressing arm 15b is attached to the end on the side wall 11 side.
Here, the support bracket 16 is set to be sufficiently higher than the height at which the attacker 7 passes, and the skewed portion s is determined from the height.
A cam mounting portion h is provided horizontally at the end of the cam mounting portion h. Therefore, if the entire cam mounting arm portion 15a is a single horizontal one, the bracket 16 must be lowered, and if so, the bracket 16 comes to the height of the attacker 7 and will collide. Therefore, the collision is eliminated by forming the skewing portion s. Normally, the bolt is located at an intermediate height of the long hole 18 °, but is adjusted up and down as necessary. The cam 19 has a first cam 19a and a second cam 19c protruding downward on the lower surface thereof, and has a horizontal recess 19b therebetween. When the attacker 7 hits the first cam 19a, one end 15a of the swing arm 15 is lifted, and the other end 15b is lowered,
The lifting rod 20 is lowered. Thereby, the cable 2
The weir 13 descends greatly through 1 and even large scum is attracted into the trough 9. When the attacker 7 corresponds to the dent 19b, the weir 13 slightly floats but still slightly sinks. Since the dimension between the water surface 3 and the upper end of the trough 9 is reduced, the flow velocity of the water surface 3 is increased, and the water surface 3 is attracted to the scum far from the trough 9 and is attracted to the trough 9. Then, when the attacker 7 hits the second cam 19c, the weir 13 comes down again greatly, whereby the sucked scum is
You will be attracted into the trough 9 regardless of the size. Thus, scum is smoothly and reliably removed regardless of the size. In addition, in this embodiment, both ends of the weir 13 and the guide 10 are connected to the trough 9.
Is sealed by a side seal rubber 12 protruding from the trough 9 perpendicular to the longitudinal direction of the trough 9 so as to maintain a watertight state, and the side seal rubber 12 includes a portion formed in a curved plate shape when viewed from above. Is a flexible portion. The direction in which the flexible portion protrudes in a curved plate shape is the direction facing the side wall 11 of the treatment pond. Various methods are considered as means for linking the weir 13 from the swing arm 15. 1 and 2 are configured by combining a lifting rod 20 and a cable 21. That is, the rod guide 22 is provided on the side wall 11, and the elevating rod 20 that vertically moves up and down is provided on the rod guide 22. The lifting rod 20 is configured to always return upward by the return spring 23.
The cable 21 is composed of an outer cable guide and an inner cable core. The cable guide is attached by cable supports 24 and 25. One end of the cable core passes through the guide to the upper end of the lifting rod 20, and the other end. Are attached to the cable end connection pipe 14. Therefore, when the lifting rod 20 moves up and down, the front and rear weirs 13 are similarly moved up and down by the cable 21. The cam 19 is arranged below the chain, but may be arranged so as to face upward. By the way, the cable
