The present invention relates to a moss removal device for a sewage treatment plant, and more particularly, when the supernatant water is sucked and sprayed through an underwater pump to automatically remove moss inhabiting the sedimentation tank, the injection pressure is concentrated and increased to remove moss. The present invention relates to a moss removal device for a sewage treatment plant having the best efficiency.

Generally, sewage treatment plants are installed in various sewage treatment plants to remove excess sludge contained in sewage using gravity. Such a sedimentation tank is usually constructed in a circular shape having a predetermined height and a diameter and a depth of several tens of meters, and an inner wall is formed at the edge of the outer wall to form a donut-shaped channel in which only the upper part is opened between the outer wall and the inner wall. Part of the channel is provided with a separate transfer line is configured to discharge the supernatant flowing along the channel. In addition, a bridge is installed in the upper part of the settling tank so that the operator can pass through the center, and a sludge remover is installed at the bottom of the settling tank to sweep and remove the sludge while rotating about the center of the settling tank.

However, in such a precipitation tank, moss (algae microorganisms, pathogenic microorganisms, etc.) inhabit the wall or the bottom of the water channel, which causes a problem of contaminated effluent. In other words, if the moss inhabiting the waterway is not removed within a short period of time, it increases exponentially, causing odors as well as adversely affecting the water quality and causing discomfort in appearance.

Conventionally, in order to remove such moss, a method of cleaning by a manpower, using a high pressure washer or various detergents, or painting a paint containing heavy metals to remove moss or reducing growth is used. None of the methods could be a fundamental solution. In particular, the cleaning method by the manpower is the most commonly used method, which has a labor cost burden, accidents can occur when cleaning, there was a problem that the cleaning worker is always exposed to skin diseases by microorganisms.

The electrical current collector 182 is grounded to the outer circumferential surface of the compact bar 184 and is configured to flow a current while moving along the outer circumferential surface of the compact bar.

Now, the operation and operational effects of the present invention thus constructed will be described.

In the present invention, the submerged algae inhaled in the water channel 12 of the sedimentation tank 10 by water pressure by injecting the supernatant while the submersible pump 110 is operated and sprayed through the first spray nozzle 130 and the second spray nozzle 140. Will be removed.

In particular, the present invention, while the first spray nozzle 130 and the second spray nozzle 140 is rotated along the water channel 12 while moving along the sludge remover 20, each injection nozzle is approximately orthogonal to the water channel. Since the reciprocating movement is performed at a predetermined angle in the direction of the pressure, the water channel 12 is cleaned as a whole.

4A and 4B, the operation of the spray nozzle, which is a feature of the present invention, will be described in more detail. The driving motor 150 is operated to rotate the worm wheel 154 and is connected to the worm wheel 154. The first swivel 160 and the second swivel 170 are rotated. Then, the first spray nozzle 130 receives the power of the first swivel 160 to the left and right reciprocating movement toward the wall surface and the bottom surface of the water channel 12, and receives the power of the second swivel 170 The second spray nozzle 140 reciprocates left and right toward the upper surface of the inner wall 12b of the water channel 12.

That is, when the first swivel 160 rotates, the rack support 162 reciprocates inclined upward and downward, and when the rack gear 164 provided in the rack support 162 performs up and down operation, the rack gear ( The pinion gear 166 meshed with the 164 rotates, and the pinion gear 166 rotates the first spray nozzle 130 cold while repeating the forward rotation or the reverse rotation.

Next, when the second rotary table 170 rotates, the connecting table 172 is reciprocated in the left and right directions to be inclined at a predetermined angle, and the link 178 connected to the connecting table 172 is also inclined at a predetermined angle and reciprocating in the left and right directions. As a result, the support bracket 176 reciprocates the second spray nozzle 140 in the lateral direction while reciprocating the left and right together with the link 178.

At this time, the rotation angle of the first injection nozzle 130 and the second injection nozzle 140 is set by controlling the rotational force of the drive motor 150.

On the other hand, according to the present invention, the auxiliary horizontal bar 106 is installed at the lower portion of the main horizontal bar 104 along the waterway 12 so as to be movable in the front and rear directions, and the spraying nozzle is installed on the auxiliary horizontal bar. When the wheel 108a of the) moves along the waterway, even if there is a gradient part, the auxiliary horizontal bar moves in the front and rear direction to help the up and down flow of the injection nozzle, thereby helping to maintain a constant distance from the bottom of the waterway.

As described above, the present invention not only moves the first injection nozzle and the second injection nozzle along the channel, but also each jet nozzle reciprocates at a predetermined angle around the flexible pipe along the wall and bottom of the channel. The water is sprayed as a whole, so that the channel can be cleaned thoroughly. In particular, the present invention is not sprayed by the sprayed supernatant through a plurality of injection nozzles, the injection pressure of the supernatant water by one injection nozzle installed in the channel and another injection nozzle installed on the inner surface of the channel Since it is concentrated and sprayed, there is an advantage that can remove the moss reliably. In other words, the concentrated spray method has the advantage of removing the moss reliably through a large amount of water spray and high water pressure. In particular, when the water is injected through the nozzle in the water flowing in the water channel, the present invention has the advantage of removing the moss completely while causing a vortex because the injection amount is high and the water pressure is high.

In addition, the present invention can control the drive motor to adjust the angle of the injection nozzle by the desired angle by adjusting the rotation range of the worm wheel, and thus has the advantage of intensively cleaning the necessary portion.

In addition, the present invention has the advantage that the wire is not twisted because the current is supplied by using the current collector and the compact bar.

In addition, the present invention is an automatic cleaning of the waterway by continuous unmanned operation using the discharge water, there is no waste of manpower, safety accidents do not occur, there is an advantage of excellent cleaning efficiency.

As described above, according to the present invention, the first spray nozzle and the second spray nozzle move along the waterway, and each spray nozzle cleans the waterway as a whole by reciprocating and transporting around the flexible pipe along the wall and bottom of the waterway. In addition to cleaning, since the water supplied through the transfer pipe is concentrated by one or two injection nozzles, there is an effect of more reliably removing moss.

While the invention has been shown and described in connection with specific embodiments as described above, it is well known in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone who owns it can easily find out.
