Description

Description: TECHNICAL FIELD The present invention relates to a fountain device in a sewage treatment tank, a fish pond, or the like.

(Prior Art) Conventionally, a fountain device is used to dissolve oxygen in a treatment tank of a sewage treatment device using microorganisms, a fish pond, and the like, and a strainer is provided so as not to suck dust and fish.

(Problems to be solved by the invention) In a fountain device used in a sewage treatment tank, a fish pond, or the like, a plate member is provided with a large number of holes so as not to suck dust and fish, and a large number of rod members are installed. Strainer was installed, but it was expensive and expensive to manufacture.

(Means for Solving Problems) A frame body is formed by vertically connecting a plurality of column members such as pipes to the outer periphery of a vertically oriented water flow generator with a connecting member, and an upper portion of the frame body. A float was attached to the outside, a spring-like body was inserted from the lower side between the frame and the water flow generator at a substantially middle portion of the inside of the frame, and a bottom plate was attached to form a strainer.

(Operation) Since it is made as described above, it can be easily manufactured by simply welding the column materials such as pipes and attaching the spring-like body, which is inexpensive, and the spring-like body can easily be separated depending on the size of dust or fish. The spacing can be adjusted.

(Examples) Examples of the drawings will be described below. Reference numeral 1 is a water flow generator that rotates a blade 2 to generate a water flow, and a frame body 4 having a float 3
It is fixed so as to generate upward water flow through the draft ring 5. Numerals 6 and 7 are fittings for attaching the water flow generator 1 to the draft ring 5.

The draft ring 5 is fixed to the frame body 4 so as to face upward inside the float 3 so as to surround the blade 2.

In the frame body 4, pillars 8 such as pipes are arranged on a circumference slightly larger than that of the water flow generator 1 and are connected by an upper connecting member 9 and a middle connecting member 10. The fixed portions 11 and 11 are fixed to the outer substantially central portion of the.

The float 3 has a donut shape, and an upper plate 12 attached to the upper portion of the frame body 4 and a lower member attached to the fixing portions 11 and 11 of the frame body 4.
Hold it with 13, and attach the upper plate 12 with the attaching part 12a and the lower plate 13 with the attaching part 13a.
The connecting member 14 is attached to the. 15 for the connecting material 14
15 is stuck.

The intermediate wall 16 is a conical portion 16a whose upper side is open upward and a lower portion is a cylindrical portion 16a.
Upper and lower communication holes 16c are provided at the boundary between 6a and the cylindrical portion 16b, and are supported from the draft ring 5 by a plurality of support members 17.

Reference numeral 18 is an extension shaft of the rotary shaft 19 of the blade 2 and is connected to the rotary shaft 19 by screwing it. The upper body 19 having a conical upper and lower surface and a blade body 19a fixed to the outer side is attached to the upper portion thereof. Yes,
A narrow gap is provided between the intermediate wall body 16.

A lower wall 20 is a conical portion 20a on the upper side, a lower portion is a cylindrical portion 20b that slides inwardly on the outer periphery of the draft ring 5, and a lower half of the cylindrical portion 20b is a cutout portion 20c. Notch
Fastening ears 20e having bolt holes 20d are secured to both sides of 20c.

Reference numeral 21 denotes a band, and tightening ears 21b having bolt holes 21a are provided at both ends of an arc-shaped band which is slightly shorter than the arc length of the notch 20c. The lower wall body 20 is attached to the upper part of the draft ring 5 by sandwiching the draft ring 5 with the band 21 and tightening with bolts.

Reference numeral 22 denotes a horizontal pressing plate, which is a circular plate having a concentric hole formed therein for sliding inwardly on the outer periphery of the upper portion of the intermediate wall body 8. The circular arc-shaped 22b is fixed to the upper half of the concentric hole 22a so as to be flush with the concentric hole 22a. Has a bolt hole 22c
The tightening ear portion 22d having the above is provided.

Reference numeral 23 is a band, and tightening ears 23b having bolt holes 23a are provided at both ends of an arc-shaped band slightly shorter than the arc length of the arc portion of the concentric hole 22a to which the arc member 22b is not fixed.

The horizontal holding plate 22 is attached to the outer periphery of the upper portion of the intermediate wall body 16 to form a band.
The upper part of the intermediate wall body 16 is sandwiched between 23 and 23, and the intermediate wall body 16 is fastened with bolts and attached.

Reference numeral 24 is a spring-like body which is inserted from below between the frame body 4 and the water flow generator 1, and the bottom plate 25 is fitted and fixed in the recess 8a of the column member 8 such as a pipe. A communication hole 25a is formed in the bottom plate 25. The spring-like body 24 and the bottom plate 25 form a strainer 26.

The spring-like body 24 is manufactured in the form of a long coil, and is cut to an appropriate length and compressed at the time of use, and the strainer 26 is used with its eyes changed depending on the size of dust and fish.

27 is a power supply cable of the water flow generator 1 and is connected to a power supply on the ground not shown. P is a fish pond and 28 is a mooring rope.

Then, the present invention is moored at a predetermined position in a fish tank or the like by the floating mooring rope 28 so as not to move. When power is supplied from the power supply cable 27, the blades 2 of the water flow generator rotate and the water around the frame 4 flows in through the gap between the wire rods of the spring-like body 24 of the strainer 26 and the communication hole 25a of the bottom plate 25, and the draft ring 5 is introduced.
Is sucked in and water flows upward. The bottom plate 25 of the spring-like member 24 prevents fish and dust from flowing into the water flow generator 1, so that dust and foreign matter are not clogged and the fish in the fish tank is not damaged. When the fish in the fish tank is small or the dust in the processing tank is small, use the spring 24 with a small pitch, and the communication hole of the bottom plate 25.
It can be appropriately adjusted according to the size of the fish or dust such as using a small one of 25a.

Most of the upward water flow generated in the draft ring 5 passes between the draft ring 5 and the intermediate wall body 16 between the lower wall body 20 and rises, and is held down by the horizontal holding plate 22. The water flow radiates horizontally in a horizontal direction to form a lower fountain D, which drops over the float 3 to the surrounding water surface, splashes water droplets on the water surface, and entrains air bubbles into the water for aeration.

In addition, a part of the upward water flow in the draft ring 5 is an intermediate wall body.
It passes through the communication holes 16c of 16 and flows out to the upper side of the intermediate wall body 16,
The blade body 19a sprays water higher than the gap between the upper body 19 and the intermediate wall body 16 to improve the appearance as the upper-stage fountain U.

(Effect of the invention) As described above, the present invention forms a frame body by vertically connecting a plurality of column members such as pipes to the outer periphery of a vertically oriented water flow generator with a connecting member, and While attaching the float to the outside of the upper part, support the water flow generator at the inner middle part of the frame,
Since the strainer is formed by inserting the spring-like body from the lower side between the frame body and the water flow generator and attaching the bottom plate, it is easy to weld the column materials such as pipes and attach the spring-like body. It can be manufactured and is inexpensive, and the gap of the spring-like body can be easily adjusted depending on the size of dust and fish, and can be easily adapted to the usage environment.
