DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, in FIG. 1, reference numeral 1 denotes a body. This body 1 comprises a relatively thick vertical pipe 2 and an inflow pipe 3 and an outflow pipe 4 which are arranged in a straight line with the vertical pipe 2 interposed therebetween. It is formed in a cross shape. Reference numeral 6 denotes a cover body for closing the upper end of the vertical pipe 2 of the body 1, and an element body 6 is inserted into the vertical pipe 2. Note that FIG. 7 shows a fluid passage of the fluid.

FIGS. 2, 3, and 4 are a vertical sectional view, a front view, and a plan view showing the details of the element body 6, and a pair of disk bodies 8 for closing the upper and lower ends of the vertical pipe 2. , 9 and a pair of spring-plate-shaped side plates 11, which connect these disc bodies 8, 9, and which are elastically slidably contacting opposed inner walls 10 of the vertical pipe 2.
12 and a porous element 13 interposed between the side plates 11 and 12 and traversing the fluid passage 7, and from the disks 8 and 9, a pair of upper handles 14 and 15, a pair of lower rings 16,
17 are protruded.

FIGS. 5 and 6 are a vertical sectional view and a plan view showing details of the cover 5, in which the upper handles 14 and 15 are clamped to prevent the element body 6 from rotating. Are mounted.

In the embodiment having the structure shown in each of the above-mentioned drawings, the details will be described mainly with reference to FIG. 1. The side plate 1 of the element body 6 is attached to the inner wall 10 of the vertical pipe 2 of the body 1.
1 and 12 are combined with body 1 so that a spring effect is obtained.
The lower rings 16 and 17 are inserted from above the vertical pipe 2, and the lower rings 16 and 17 are inserted from above the vertical pipe 2.
7 is fixed so as to contact the upper surface of the bottom plate 20 of the vertical pipe 2. In this case, the insertion direction of the element main body 6 is set so that the surface of the serrated element 13 faces the inflow pipe 3 at right angles.

Next, the flange portion 21 above the vertical pipe 2
Place the O-ring 23 in the O-ring groove 22 of the
Put 5 on it. In this case, as shown in FIGS. 5 and 6, the upper handles 14, 15 are inserted so as to be clamped by the detent frames 18, 19 of the element body 6 while the flange portion 24 of the cover 5 is inserted. And the flange portion 21 are overlapped, and are appropriately connected with bolts, nuts, or the like.

Next, the element body 6 shown in FIGS. 2, 3 and 4 will be described. The porous element 13 includes:
In the embodiment shown in the figure, the staggered porous body (punched plate) of φ5 × P8 × 60 ° is formed, and therefore, impurities such as dust, foreign matter, and foreign matter in a fluid (hereinafter referred to as water). Is captured by the porous element 13.

The reason why the porous element 13 is formed in a sawtooth shape is to increase the effective passage area of the water flow, and to increase the effective passage area several times as compared with the flat plate element. The pressure loss value of the flowing water stream can be reduced. That is, the pressure loss of the water flow due to the strainer is a large subject in hydrodynamics,
In that respect, it has a great effect.

In addition to the illustrated embodiment, the porous element may be a woven mesh or a wedge wire screen. That is, the most suitable type is selected according to the size of the impurities to be captured by the porous element 13 and its properties. Therefore, if necessary, a plate-shaped one instead of a saw-tooth-shaped one can be used.

Next, the side plates 11, 12 on both sides of the above-described porous element 13 will be described. This is because, as described above, the element body 13 is attached to the inner wall 10 of the vertical pipe 2 during assembly.
The side plates 11, 12 are inserted from above with a spring effect, and the spring effect allows the water flow when the water flow passes through the strainer of the present invention. Has the effect of preventing lateral vibration and lateral vibration of the element body 6 due to the above. That is, by this, the element main body 6 is free from lateral vibration and lateral vibration,
It can be fixed.

As described above, the lower rings 16 and 17 are assembled so as to contact the upper surface of the bottom plate 20 at the bottom of the vertical tube 2, and as an effect, the lower rings 16 and 17 are formed by forming flat plates into a ring shape. Therefore, the ring is pressed in such a manner that it is slightly deformed into an elliptical shape, and a spring effect is generated by the slight deformation.

Similarly, the upper handles 14, 15 are pressed against the curved upper inner wall of the cover 5 as shown in FIG. 1 which is an assembly drawing of the strainer / rectifier of the present invention. Therefore, as in the case of the lower rings 16 and 17 described above, the spring effect is generated by the pressure contact so as to be slightly deformed.

As described above, due to the spring effect of both rings of the upper rings 14 and 15, which are also ring-shaped, like the lower rings 16 and 17, when the water flow passes through the strainer / rectifier of the present invention, the element due to the water flow. This has an effect of preventing vertical vibration and vertical vibration of the main body 6. That is, by this, the element body 6 can be stably set without any vertical vibration or vertical vibration.

The upper handles 14, 15 are used for assembling the element body 6 by inserting it into the vertical pipe 2,
When cleaning is necessary, for example, when the porous element 13 is clogged due to use, it acts as a handle for inserting and pulling out the element.

Further, as described above, the upper handles 14, 15 are used for assembling the strainer rectifier of the present invention.
Since the element body 6 is held between the inflow pipes 19, the element body 6 does not rotate due to the water flow and does not face the inflow pipe 3 at right angles. That is, there is an effect of preventing the rotation of the element body 6.

The vertical pipe 2, the inflow pipe 3 and the outflow pipe 4 constituting the body 1 can be integrated by welding.
It is also possible to perform integral casting, and the strainer / rectifier of the present invention can be used not only for water but also for other fluids.

[0022]

According to the present invention, there is provided a storage having the above structure.
By using the rectifying device, the turbulent water flow from the upstream side of the strainer rectifying device and flowing from the inflow pipe is converted into a rectified water flow by passing through the element body. Since it flows out of the outflow pipe, it is possible to prevent the inflow of impurities into the downstream working equipment due to the dust removing action, and to ensure the stable operation of these working equipment.
