Description

  The present invention relates to a water purification device that purifies water by aggregating and collecting suspended substances by rotating water to be treated.

  When water is rotated in the container, the suspension collects in the center. Suspensions heavier than the specific gravity of water collect at the bottom and light suspensions collect at the top.

  For example, Patent Document 1 discloses a water quality purification method for lakes and marshes using water flow. The system of Patent Document 1 generates a water flow in a lake and eliminates oxygen deficiency at the bottom of the lake, and levitates and collects sludge.

It was set as the water purification apparatus structure described in 1.

  In the present invention, by rotating the water to be treated in a circular pool, the aggregates can be collected at the top and bottom of the pool center, and the aggregates can be easily recovered. Further, by using wind power as an auxiliary, the water purification device can be operated at low cost. Furthermore, by generating power with surplus energy and using the power, further low-cost operation becomes possible. In addition, since it is movable, there are no restrictions on movement and installation location.

It is a partial perspective side view of the water purification apparatus which is the present invention. It is a top view of the water purification apparatus which is this invention. FIG. 1A is a cross-sectional view taken along a broken line.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  As shown in FIGS. 1 and 2, the water purification apparatus 1 according to the present invention rotates to a circular pool 2, a water supply pipe 3 for injecting water to be treated into the circular pool 2, and a column 4 b erected in the circular pool 2. A rotating blade 4 that can be attached and rotated by jetting of the water to be treated, a first conveyor 7 that discharges floating substances aggregated at the center of the water surface 13 of the water to be treated in the circular pool 2, and a target in the circular pool 2 The discharge pipe 9 discharges the treated water from the middle layer of the treated water, and the pressure feed pipe 10 discharges the sediment from the bottom of the circular pool 2.

  And the to-be-processed water rotates with rotation of the rotary blade 4 to collect the suspended substance after agglomeration.

  The circular pool 2 is a container that holds rotating water to be treated, is held by legs 2b, and is installed on land or on a ship. The bottom of the circular pool 2 can efficiently aggregate agglomerates having a specific gravity higher than that of water at the center of the bottom by forming the bowl portion 2a.

  The water supply pipe 3 injects the water to be treated into a jet water flow 3a by a pump (not shown) and injects the water to be treated toward the rotary blades 4 in the circular pool, thereby causing the water to be treated to move circularly. As water to be treated, any water such as rivers, lakes, and seawater can be used. The jet water stream 3a is ejected intermittently. The injection control is performed by a timer or the like with a separate control device.

  The rotary blade 4 is erected from the base 4c, is fitted rotatably with the cylindrical portion 4a fitted on the top of the pillar 4b inserted into the circular pool 2, and is partially buried in the water to be treated. As shown in FIG. 2, a plurality of rotating blades 4 are provided radially from the cylindrical portion 4a. Then, the jet water stream 3a is rotated by water pressure. In order to make the rotation of the rotary blade 4 smooth, it is preferable to provide means for suppressing the frictional resistance between the inside of the cylindrical portion 4a and the column 4b. For example, bearings and tops are listed.

  The water to be treated in the circular pool 2 rotates based on the rotation of the buried rotary blade 4. Even if the jet water flow 3a stops, the rotational motion of the water to be treated continues to rotate due to inertia. Meanwhile, aggregates lighter than the specific gravity of water gather at the center of the water surface 13, and aggregates heavier than the specific gravity of water gather at the bottom of the circular pool 2.

  At this time, the aggregation effect is enhanced by adding a flocculant. Examples of the flocculant include known aluminum sulfate, ferric chloride, diaphragm, shell fossil powder and the like according to the hydrogen ion concentration of the water to be treated.

  As shown in FIG. 3, the portion of the rotary blade 4 located on the upper surface of the water surface 13 is a wind receiver 4 d bent in the counter-rotating direction. With such a structure, the rotation of the rotary blade 4 is assisted by the wind in the rotation direction (arrow on the right in the figure). On the other hand, the wind in the counter-rotating direction (the arrow on the left in the figure) is received and the reduction in the rotational force of the rotary blade 4 is minimized.

  The first conveyor 7 has a tip positioned in the vicinity of the water surface 13 in the circular pool 2, scrapes up the aggregate floating at the center of the water surface 13, and discharges it outside the circular pool. Furthermore, the 2nd conveyor 8 is provided and the aggregate collect | recovered with the 1st conveyor 7 is carried in to a processing facility, a vehicle, etc. (not shown).

  The discharge pipe 9 is a pipe that draws and discharges water (treated water) purified from the middle layer of the treated water in the circular pool 2 by flowing down or using a pump (not shown).

  The pressure-feed pipe 10 is a pipe that discharges aggregates precipitated at the bottom of the circular pool 2 to the outside of the circular pool by a pump (not shown).

  A drainage groove 12 that receives water overflowing from the circular pool 2 (overflow water) may be provided over the entire circumference of the circular pool 2. The overflow water in the drainage groove 12 is connected to a pump (not shown) that is pumped down or returned to the sampling site of the water to be treated. By providing the drainage groove 12, it is possible to prevent environmental pollution due to leakage to the vicinity of the place where the water purification apparatus 1 is installed even if the water to be treated contains toxic substances or the like.

  Further, the water purification device 1 can include a large gear 5 that is fixed to the rotary blade 4 via the connecting portion 4 e and rotates together with the rotary blade 4, and a generator 6 that generates electric power by the rotation of the large gear 5. The large gear 5 is heavy and exhibits a function as a flywheel.

  The transmission of the rotational motion to the generator 6 may be through the small gear 6a and the bevel gear 6b, instead of directly connecting the gear of the generator 6 and the large gear 5. The transmission direction is appropriately changed using various gears depending on the installation position of the generator. A plurality of generators 6 may be provided and used for braking force.

  The surplus rotational energy of the water to be treated and the power generated by the generator 6d using wind energy are the driving power of the pumps provided in the water supply pipe 3, the discharge pipe 9, and the pressure feed pipe 10, the first and second conveyors 7, By using the drive power of 8, the running cost of the water purification device 1 can be kept low, which is economical.

  In order to position the first conveyor 7 on the water surface 13 in the large gear 5, a hole 5b is formed at the center as shown in FIG. Although the rotational force is transmitted from the outer peripheral portion of the large gear 5 to the generator 6, it is also possible to transmit the rotational force to the generator 6 by providing teeth in the holes 5 b.

  In the case where the water purification apparatus 1 includes the large gear 5, the roller 5a depending from the large gear 5 to support the large gear 5, the travel path 11 on which the roller 5a travels around the outer periphery of the circular pool 2, and the left and right of the roller 5a In addition, it is desirable to provide a guide 11 a erected on the traveling path 11. The guide prevents the roller 5a from dropping, that is, vibration of the large gear 5.

  The roller 5a is preferably made of a material that does not reduce the rotation of the large gear 5, that is, the rotational force of the rotary blade 4 and the water to be treated. For example, a rubber tire has excellent contact pressure. Furthermore, exchange is also easy.
