Description

[Detailed description of the invention] In this invention, a rotary frame is rotatably provided on a fixed frame, a rotatable nozzle and a turbine are attached to the rotary frame, the nozzle is reciprocated by the rotation of the turbine, and the liquid jet force from the nozzle is This invention relates to a liquid ejecting device that rotates a rotary frame to clean a hollow frame or stir the liquid inside.

As is well known, various liquid injection devices are known for cleaning the inner surfaces of large-scale hollow frames such as oil tanks and water tanks, and for stirring the liquid inside.

However, conventional injection devices are large and impractical.

Furthermore, since the direction of liquid jetting is continuously changed using a motor or other driving source, extra driving force is required.

The present invention has been devised in view of the above, and is extremely compact, and is capable of efficiently cleaning the inner surface of the hollow frame and stirring the liquid inside.

The present invention will be explained below with reference to the illustrated embodiment. The liquid ejecting device 1 of the present invention comprises a fixed frame 2 and a rotary frame 3 rotatably attached to the fixed frame 2.

The fixed frame 2 has a vertical cylindrical shape, and has a flange 4 at its lower end that is fixed to, for example, a frame installed inside the hollow frame, and has a liquid flow path 5 that is open at the lower end.

On the other hand, the rotating frame 3 has an inverted main channel 8 consisting of a vertical channel 6 and a horizontal channel 7, and a mounting tube 9 is provided on the lower outer periphery of the vertical channel 6.

Then, the lower end of the vertical channel 6 is attached to the inner surface of the channel 5 watertightly and rotatably, and the outer surface of the channel 5 and the mounting tube 9
A rotary support member 10 such as a bearing washer is interposed between the rotary frame 3 and the inner surface of the fixed frame 2 to rotatably support the rotary frame 3.

Further, the horizontally facing base end 12 of the nozzle 11 is watertightly and rotatably attached to the opening tip of the horizontal flow path 7.
A rotary support frame 13 such as a bearing washer is interposed between the outer periphery of the nozzle 2 and the rotary frame 3 to support the nozzle 11 rotatably around the horizontal flow path 7.

Since the nozzle 11 has a downwardly directed liquid jet port 14, the flow path 5 is connected to the jet port 14 in an inverted U-shape by a vertical flow path 6 and a horizontal flow path 7.

A mechanism chamber 15 is installed above the main flow path 8, and the mechanism chamber 15
A casing 16 is provided on one side of the.

This casing 16 has openings 17 on each of the upper, lower, left, and right sides.
... and houses the turbine 18 inside.

This turbine 18 is attached to the tip of a turbine shaft 19 provided so as to cross the mechanism chamber 15. A crankshaft 20 and a turbine shaft 19 are provided inside the mechanism chamber 15 so as to be orthogonal to the turbine shaft 19.
are connected by a rotation transmission mechanism 23 consisting of, for example, a worm 21 and a worm wheel 22.

Therefore, when the turbine 18 rotates, the crankshaft 20 also rotates from the turbine shaft 19 via the rotation transmission mechanism 23.

A thin sub-channel 24 is opened at the bent portion of the vertical channel 6 and the horizontal channel 7 of the main channel 8 described above, and the tip of the sub-channel 24 is opened inside the casing 16, so that the water flows through the main channel 8. A portion of the liquid is guided to the sub-flow path 24 and jetted into the casing 16, and the turbine 18 is rotated by the force of the jetted liquid.

One end of the above-mentioned crankshaft 20 projects outward from the mechanism chamber 15, and the proximal end of the link par 25 is fixed to the projecting end.

One end 27 of a link lever 26 is pivoted to the tip of the link par 25, and the other end 28 of the link lever 26 is pivoted to the base end 12 of the nozzle 11 described above.

Due to the link mechanism consisting of the link par 25 and the link lever 26, when the link shaft 20 rotates, the link par 25 also rotates, and the link lever 26 reciprocates.
The reciprocating rotation of the link lever 26 causes the nozzle 11 to reciprocate around the horizontal flow path 7.

The present invention is constructed as described above, and in actual use, the fixed frame 2 is installed on the top surface of the mount provided inside the hollow frame body, and the liquid supply pipe is connected to the flow path 5 from below. .

When liquid is supplied from this supply pipe to the flow path 5 at high pressure, the liquid passes through the vertical flow path 6, the horizontal flow path 7, and the inside of the nozzle 11, and is ejected from the spout 14.

On the other hand, a part of this liquid is transmitted through the sub-flow path 24 and rotates the turbine 18 .

When the turbine 18 rotates, the crankshaft 25 continuously rotates due to the rotation of the turbine shaft 19 and the crankshaft 20 as described above, and the nozzle 11 reciprocates within a certain angle range by the crank lever 26.

When the nozzle 11 is reciprocated by the crank mechanism, a rotational force is applied to the rotating frame 3 when the nozzle 11 faces in a direction other than the vertical direction directly below due to high-pressure ejection of liquid.

For example, if the nozzle 11 reciprocates through the angle shown in FIG. 1, a horizontal rotational force due to the liquid jet force is applied to the rotating frame 3 except when the nozzle is facing downward as shown by the solid line. It turns out.

Therefore, the rotating frame 3 always rotates in the horizontal direction about the fixed frame 2, and together with the reciprocating rotation of the nozzle 11 described above, the liquid from the spout 14 is evenly sprayed onto the inner surface of the hollow frame. It is.

In addition, the liquid ejected from the sub-flow path 24 rotates the turbine 18, and is scattered from each opening 17 of the casing 16 by the rotational force of the turbine, so that it contributes to cleaning the inner surface of the hollow frame and stirring the liquid inside. become.

In particular, the liquid ejected from the sub-flow path 24 is highly effective in cleaning blind areas other than the area cleaned by the nozzle 11.

As is clear from the above, according to the present invention, a part of the liquid ejected from the nozzle is guided to the turbine to rotate the turbine, and the rotation of the turbine causes the nozzle to reciprocate in the vertical direction, and the ejection pressure of the liquid ejected from the nozzle The rotary frame is rotated in the horizontal direction.

Therefore, when cleaning the inner surface of the hollow frame, the inner surface of the hollow frame can be cleaned evenly by simply installing a fixed frame inside and pumping the cleaning liquid into the flow path of the fixed frame.

In addition, when stirring the liquid inside the hollow frame, the proposed device is installed inside the frame and submerged in the liquid, and the same liquid as the liquid inside the frame is pumped into the flow path of the fixed frame. be.

As a result, the liquid ejected from the nozzle due to the reciprocating rotation of the nozzle and the rotation of the rotating frame sufficiently agitates the liquid inside the frame.

Therefore, according to the present invention, cleaning and agitation of the hollow frame are efficiently performed.

Furthermore, the angle of the nozzle's reciprocating swivel range and the position of the swivel range can be freely adjusted by changing the length of the crank lever or by operating the crank par or the nozzle's pivot position on the outer surface of the rotating frame. Can be used for multi-purpose cleaning,
Since stirring can be performed, it can be used for hollow frames of all sizes.

In particular, when the hollow frame is large-scale, several nozzles may be installed inside and the liquid ejection direction of each nozzle may be freely determined.

In addition, if a liquid flow rate adjustment mechanism (e.g. a valve) is provided in the sub-channel 24, or a direction-variable nozzle is provided at the tip,
Since the injection pressure and direction of the liquid ejected from the sub-flow path can be freely adjusted, the rotating speed of the nozzle 11 can be adjusted by changing the rotation speed of the turbine 18.

Furthermore, since the liquid ejected from the sub-flow path is ejected in a direction other than the direction of the liquid ejected from the nozzle while rotating the turbine, it is possible to reliably clean the blind spot of the liquid ejected from the nozzle.

Further, since the rotary frame rotates around the fixed frame due to the jetting force of the liquid jetted from the nozzle, rotation is easy, and the structure is simple and can be made compact.

In addition, in the present invention, the turbine is not located in the main flow path of the rotating frame, but is located outside and is rotated by the liquid ejected from the sub flow path, so there is no pressure loss in the liquid guided from the main flow path to the nozzle. , the pressure of the liquid jetted from the nozzle becomes high, and a sufficient cleaning effect can be expected.
