十分な付着物の除去を行うことができなかった。<Conventional technology> Conventionally, for example, in a steelworks, an inclined plane screen is used in the pre-process of a blast furnace to sieve fine grains and powdery raw materials in the raw material fed to the blast furnace, so that particles with a constant particle size are fed into the blast furnace. The above raw materials are charged, but during the sieving process, fine grains and powdery raw materials in the raw materials may get stuck in the sieve holes on the screen surface as if they were wedged into the sieve holes. The fine powder in the raw materials grew and adhered to the screen surface, blocking the sieve holes and significantly reducing the efficiency.For this reason, after sieving, these deposits were removed by hand by washing with water, but since this was done manually, it was time-consuming. Since the frequency of work is limited,
It was not possible to remove the deposits sufficiently.

There have been proposed devices that move the top of the screen, and devices that move a plurality of swinging nozzles on a trolley as shown in Japanese Patent Laid-Open No. 59-142813.

ど防止される。When the high-pressure water supplied from the water supply pipe 3a enters the rotating nozzle 2, the flowing energy of the high-pressure water and the reaction force of the high-pressure water jetting from the tip of the rotating nozzle 2 cause the rotating nozzle 2 to The cleaning water rotates dimensionally and spouts high-pressure water around it, and within the time it takes, the cleaning water collides with the screen surface 1a while drawing a trajectory as shown by the continuous curve from point A to point B in Figure 2, and the screen surface 1a. Clean the deposits in 1a. If the rotation range of the rotating nozzle 2, the dimensions of the screen surface 1a, and the distance from the screen surface 1a to the rotating nozzle 2 are appropriately selected, the jet flow from the rotating nozzle 2 can cover the screen surface 1a within a certain period of time. Can be washed without collision. In addition, the water supply pressure to the rotating nozzle 2 (discharge pressure of the pump 6)
and the mounting position of the autorotating nozzle 2 (the plane position facing the screen surface 1a and the distance from the screen surface 1a),
If the number of autorotating nozzles 2 to be installed is selected appropriately, that is, if it is selected so as to have a sufficient cleaning effect on a part of the corner of the screen surface 1a that is farthest from the autorotating nozzles 2, the screen surface 1
The entire surface of a can be effectively cleaned. Also, the splashing of washing water outside the screen surface 1a is
Most of the dust is prevented because it is blocked by the inner wall surface of the frame 17 erected in the enclosure and the inner wall surface of the dust prevention cover 13 provided above.

定自在な構造としてもよい。In the embodiment shown in FIG. 1, the upper end of the water supply conduit 3a to the three-dimensionally rotating autorotating nozzle 2 is directly connected and fixed to the tip of the water supply pipe 5b, but in this embodiment, the water supply conduit 3a and the water supply pipe 5b are A hose 3b is interposed between the nozzle 2 and the screen surface 1a, so that the distance between the rotating nozzle 2 and the screen surface 1a can be adjusted freely, and a part of the water supply pipe 3a can be slid up and down by a water pipe clamp device 18. It is clamped. The clamp device 18 has a slide arm 19 extending in the horizontal direction.
A part of the other end of the slide arm 19 is fitted into a slide arm holding vibe 21 and fixed at an appropriate position with a slide arm fixing fitting 20. The other end of the slide arm holding pipe 21 is fixed by a post 22 erected on a non-vibrating pedestal 23 around the screen 1. Note that the boss 22 may have a structure that can be rotated and fixed.

な位置になるように取付ければよい。Further, in the embodiment shown in FIG. 3, the cleaning liquid (water) is wasted by scattering or colliding with the surroundings other than the screen surface 1a.
A scattering prevention cover 1 is installed on the top of the rotating nozzle 2 in order to increase the cleaning effect by allowing the liquid to flow down within the range of the screen surface 1a.
The scattering prevention cover 14 consists of a side wall and a ceiling depending on the shape of the screen surface 1a (square, rectangle, or circle), and the lower end of the side wall is the outermost periphery of the jet stream from the rotating nozzle 2. It should be installed so that the part (broken line in FIG. 3) collides with the outside of the outer periphery of the screen surface 1a (i.e., the lower part of the frame 17) and blocks a part of the jet stream from the rotating nozzle 2.

It hits the side wall of 4 and the inner wall of the ceiling and flows downward, so 13
High-pressure water of about 0 kg/C1i does not scatter to the surroundings through the gap between the screen surface 1a and the dust prevention cover 14.
Since the water flowing down to the lower part contributes to cleaning the screen surface 1a, the cleaning time can be shortened.
