Abstract

PURPOSE:To well separate and remove particles in a liquid without using a filter aid agent by allowing filter cloth along the inside of a opening formed to a liquid tank and sucking the liquid in the liquid tank through the opening. CONSTITUTION:Filter cloth 12 is allowed to run along the inside of the opening 4 formed to a liquid tank 1 and the liquid in the liquid tank 1 is sucked through the opening 4. As a result, the particles in the liquid can be well separated and removed without using a filter aid agent.

(Function) According to the present invention described above, when the liquid in the liquid tank is sucked through the opening, the i-door cloth that has just faced the frontage will not have coarse particles in the liquid attached to its surface yet. , only coarse particles larger than the mesh of the filter cloth can be captured, but as the filter cloth runs opposite to the opening, the coarse particles in the liquid are captured one after another by the filter cloth, and the coarse particles gradually become thicker on the filter cloth. A layer is formed.Then, it gradually becomes possible to capture even fine particles.
On average, the liquid drawn from the entire opening is fairly clean.

Dirty liquid is supplied and stored in the liquid tank 1 from a supply pipe (not shown). In such a situation,
Drive the drive motor 7 so that the cover cloth 12 passes through the opening 4 of the inclined bottom wall 3B after passing inside the inclined bottom wall 3A.
The filter cloth 12 is moved in the direction of the arrow, and the suction bomb 17 is driven. Then, the dirty liquid in the liquid tank 1 is sucked into the resupply pipe 16 via the vacuum box 5 so as to pass through the filter cloth 12 by the suction pump 17 .

By the way, when the dirty liquid in the liquid tank 1 passes through the cloth 12, it first passes through the cloth 1 that has just faced the opening 4.
2, since the coarse particles in the Daeye liquid have not yet adhered to the surface, only coarse particles larger than the mesh of the filter cloth 12 are captured to form a coarse particle layer on the surface of the filter cloth 12. Therefore, while the i-door cloth 12 runs opposite the opening 4, the thickness of the coarse particle layer becomes gradually thicker, and even the fine particles in the dirty liquid can be gradually captured. As a result, a particle layer in which coarse particles and fine particles are mixed is formed on the filter cloth 12.

In this way, a considerable amount of particles can be captured by the time the cloth 12 passes through the opening 4, and the liquid sucked from the opening 4 into the resupply pipe 16 by the suction bomb 17 is placed at the position where it is sucked. Although the amount of particles passed through varies depending on the amount of particles passed through, the liquid sucked from the entire opening 4 is on average fairly clean.

On the other hand, the particle layer on the cover cloth 12 is conveyed to the outside of the liquid tank 1 as the cover cloth 12 runs, is pressed by a pressure roller 13, and then scraped off from the i-cover cloth 12 by a scraper 15. Thereafter, the part of the cloth 12 from which the particle layer has been peeled passes under the liquid tank 1 and reaches the inside of the liquid tank 1 again.
Repeat the process described above. On the other hand, the clean liquid sucked into the re-supply pipe 16 is supplied to a VifU device (not shown) via the re-supply pipe 16 and is reused.
