Abstract

PURPOSE:To provide a novel dehydrator capable of sucking out and dropping water by capillarity and siphoning. CONSTITUTION:This dehydrator is provided with a conveyor to send a slurry in the thinly spread state, a protrusion on the edge of the conveyor, a material of towel cloth, etc., having capillarity and laid over the conveyor at the site on which the slurry is placed and a trickling part formed by extending the outer edge of the material higher than the protrusion and hanging the protrusion down outside the protrusion.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dewatering device for removing water from water-containing materials such as mud (referred to as slurry materials in this text).

0002

BACKGROUND OF THE INVENTION Conventionally, dehydration has been carried out by heating, centrifugal force, applying pressure to a mouth cloth, etc.

0003

Problems to be Solved by the Invention The methods described in the above-mentioned prior art are undesirable because the apparatus becomes complicated and the consumption of electric power, thermal power, etc. becomes too large.

[0004] An object of the present invention is to provide a new dehydration device that does not rely on electric power or thermal power and has a simple configuration.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a conveyor for conveying a slurry-like material in a thinly spread state, a high place provided on the edge of the conveyor, and a conveyor for transporting the slurry-like material on the conveyor. A material with capillary action, such as terry cloth, laid on the area where the water will fall, and a water droplet fall area created by extending the outer edge of this material longer than the height of the above-mentioned high place and letting the extended part hang outside of the high place. It has the following.

[0006]

[Embodiment] A first embodiment shown in FIGS. 1 and 2 comprises a belt conveyor 4 having an inclined bottom 1 which is high in the center and low on both sides, and banks 2 and 3 are provided on both sides of the bottom. On the bottom surface and the inner surface of the banks 2 and 3, a terry cloth 6 with a canvas 5 that has an anti-expansion function and a reinforcing function fixed to the back side is laid in advance, and both side edges of the terry cloth 6 are extended longer than the width of the banks 2 and 3. Water droplet falling parts 7 and 8 are provided by hanging the extension parts on the outside of the banks 2 and 3.

The second embodiment shown in FIG. 3 has a trough 16 with banks 14 and 15 along both sides of a sloped bottom 1 that is high in the center and low on both sides, and a very low speed (approximately 1
A belt conveyor 18 is constituted by a belt 17 that moves at a speed of 1.5 m/min), and a towel cloth 19 is glued and laid on the upper surface of the belt 17, and the both edges of this towel cloth 19 are run over banks 14 and 15. Water droplet falling portions 20 and 21 are provided by hanging the water droplets so that they are lower than the bottom portions of the banks 14 and 15.

In the figure, reference numeral 10 indicates a rubber string inserted to prevent the water droplets from rolling up, 11 indicates a driving wheel, 12 indicates a driven wheel, 13 indicates a slurry-like material, and 23 indicates a tube for receiving water droplets.

[0009] In the present invention, a material such as felt or non-woven fabric which exhibits a remarkable capillary action can be used instead of towel cloth, and a material such as cloth or synthetic resin material can be used instead of canvas 5. The process can be carried out without the towel cloth 6 or the like in the section a shown in the figure. A squeezing device such as a roller for squeezing the towel cloth or the like can be provided at appropriate locations. Also,
It is also possible to use a heater such as a heater or a hot water heating device in combination to accelerate dehydration and drying.

0010

[Operation] Moisture absorbed by a material with capillary action such as terry cloth laid on the area where the slurry-like material is placed is guided to the water droplet falling part by capillary action and the principle of siphon, and drained from the lower edge of the part.

[0011]

[Effects of the Invention] Since the present invention has the above configuration,
It sucks out moisture using the principles of capillary action and siphoning, and dehydrates slurry-like materials without relying on electricity or firepower, and is effective enough to achieve the intended purpose.
