Description

[Detailed explanation of the idea] The present invention relates to a rotary dehydrator.

The outline of the granulated water production equipment will be explained based on FIG. 1.

1 is a slag gutter for discharging slag generated in a blast furnace, etc.; 2 is a fresh water injection device for injecting clean water onto the slag discharged from the line gutter 1 to form granulated slurry; and 3 is a water fracking gutter 3a. a distribution tank for receiving and storing granulated slurry; 4;
is a rotary dehydrator, which includes a water tank 4a for receiving the granulated slurry discharged from the supply port 3b of the tank 3;
It consists of a rotary body 4b that dehydrates the granulated slurry disposed in the a.

Reference numeral 5 denotes a dewatering tank/storage tank which receives the granulated water dewatered by the rotating body 4b via the belt conveyor 6 and the bifurcated chute 1.

Further, 8 is a sedimentation tank that temporarily stores water overflowed from the water tank 4a.

In the above configuration, since the granulated slag has hydraulic properties, it hardens and adheres to the bottom of the water tank 4a, particularly to the corners.

As a result, it becomes impossible to scrape off the granulated slag in areas other than the part where the rotating body 4b rotates.

Cleaning inside the aquarium 4a again! ti, in order to drain the water in the water tank 4a while rotating the rotating body 4b, the worker
It is dangerous to go inside and remove the granulated slag.

Therefore, the present invention proposes a rotary dehydrator that can prevent granulated slag from hardening and adhering to the inner bottom of the water tank.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

This embodiment relates to an apparatus for dewatering granulated slurry, and a water tank 4a is composed of left and right inclined side walls 10A, 10B, post-treatment inclined side walls IOC, 10D, and a bottom plate 10E.

A water collection gutter 12 is fixed to the outer peripheral edge of the upper end of the water tank 10B to form an overflow part 11, and a water collection gutter 12 is attached to the spanning plate 13 from the water collection gutter 12 at a position 1 near the center of the water tank 4a. A pair of left and right baffle plates 14 are vertically installed along the side surfaces of the rotating body 4b.

In the rotating body 4b, a partition wall 17 is disposed from the lower end of each partition plate 15 near the support shaft 16 1, and a long and narrow passage opening is connected to each fracking receiving part 1.

The partition wall 17 has a small circle A centered around the support shaft 16.
In the tangential direction (although there are many problems even if it is not tangential).

).

Therefore, even when the filter 18 rotates at a certain angle from the water surface, the lower end of the passage opening of the filter 1B does not come out above the water surface.

19 is a drive motor that rotates the support shaft 16; 20 is a bearing; these are electrically connected to the span plate 13;

Reference numeral 21 indicates a chute that receives the granulated water S from the rotating body 4b and delivers it to the belt conveyor 6.

Reference numeral 22 denotes a fluid ejecting device provided below the water level in the aquarium 4a, and is configured to eject fluid (water, air, etc.) toward the inner bottom of the aquarium 4a.

That is, the fluid ejecting device 22 has an inclined sidewall IOA, 10B.
, multiple nozzles attached to I OC10D,
The jetting directions of these nozzles are directed toward the bottom plate 10E.

Although the number and position thereof are not limited, consideration is given so that the injection fluid pressure acts on the corner formed by each of the inclined side walls 10A, IOB, 10C, 10D and the bottom plate 10E.

Note that a supply pipe 24 having a valve 23 is connected to each fluid injection device 22 .

According to the above configuration, when the granulated water slurry is supplied into the water tank 4a from the supply port 3b, the granulated water S settles and accumulates at the bottom of the water tank 4a, and the partition plate 15 sequentially scrapes this, so that the granulated water S is He was accepted into the Breaking Club and became popular.

When the granulated water receivers A that have received the granulated water S rotate upward from the water surface, the water in the granulated water S in each of the granulated water receivers A flows out of the filter 18 and into the passage opening. and is returned to the water tank 4a.

In this case, the inner end of the passageway moves above the water level later than the outer end, so the inside of the passageway becomes under negative pressure, and the water remaining inside the fracked water in the fracked receiver part A is vacuumed up. It will be forcibly removed by suction.

In addition, the water in the water tank 4a passes under the baffle plate 14, passes through the overflow part 11, and flows into the water collection gutter 12, and the water contained in this water has a relatively light specific gravity. Fine water fracture is evil, its progress is blocked by the board 14 and the water collection gutter 1
The fine water particles that hardly flow into the baffle plates 14 and accumulate between the two baffle plates 14 sink due to their own weight.

It is discharged by the rotating body 4b.

While the granulated slurry is being supplied or stopped, fluid is injected from each fluid injection device 22, thereby causing the granulated granules S that are about to reach outside the rotational trajectory of the rotating body 4b to be displaced from the rotational trajectory. The granulated water S is taken into the granulated water receiving part A as described above.

As described above, according to the present invention, the water particles in the aquarium can be actively moved within the rotation trajectory of the rotating body by the fluid injection pressure from the fluid injection device, which causes the water particles to harden and adhere to the bottom of the aquarium. This can be prevented.

This allows the inside of the water tank to be cleaned without removing water particles, and can be carried out safely even while rotating the rotating body.
