Abstract

PURPOSE:To remove a mud component of sand in good efficiency, by a method wherein collected sand precipitated onto the inclined plate of a precipitation tank is scraped up by scraper plates attached to endless chain and vibration of the plate is attenuated and fresh water is flowed out onto said inclined plate. CONSTITUTION:In a precipitation tank 1 having a bottom part of from an inclined plate 2, scraper plates 3 scraping up collected sand precipitated onto the inclined plate 2 are attached to an endless chain 5 at definite intervals as well as the chain 5 is guided by sprockets 6, 7 arranged above the tank 1. In addition, a vibrator 11 imparting attenuating vibration to the inclined plate 2 is provided to the rear surface of the inclined plate 2 as well as fresh water supply ports 12 for flowing out fresh water from the rear side are formed on the inclined plate 2 at appropriate intervals. That is, continuous rub washing is enabled to make working efficiency well as well as the removal ratio of a mud component is made well.

Description

[Detailed Description of the Invention] The present invention relates to a device used for so-called grinding ore, etc., which removes silt by scrubbing collected sand (which also eats gravel) in fresh water. , take grinding ore as an example! l
However, the explanation is not limited to this.

Conventional sand mining, etc., put gravel, sand, and water in the corner of a rotating net and wash it, or use a raking blade in a container! There is a method to do this by adding turning sand and wood pipe.The mud (silt) produced by polishing in both cases remains between the particles and acts as a lubricant, hindering the polishing process.Even if a large amount of washing water is used, the silt will not I was confused because the silt removal rate that accumulated at the bottom was over 1 good.

In view of the above, it is an object of the present invention to provide a device for massaging sand, etc., which is capable of continuous massaging, has good work efficiency, and has a good silt removal rate. In a sedimentation tank, the bottom of which is formed by an inclined plate, an endless chain with scraping plates attached at regular intervals that can scrape off the sampling tube that settles on the inclined plate is placed above the sedimentation tank. A fresh water supply means is provided which is guided by a sprocket disposed on the plate, and is provided with an impact member that causes the damped vibration to occur at an incline. There is one cleaning device for the collected sand, etc., which is stockpiled.

DESCRIPTION OF THE PREFERRED EMBODIMENTS -N of the one-time washing device of the present invention will be explained below based on the figures.

As shown in the figure, the bottom of the sedimentation tank l is formed by an inclined plate λ that is inclined upward from the input side of the collected sand to the discharge side.The upper surface of this inclined plate Jatj is made of nylon. It is made of a wear-resistant material with a small coefficient of friction (μ≦07) such as rt Himolar (trade name, manufactured by Mitsubishi Yuka Co., Ltd.). It should be noted that for Heimolar, μ=aOS.

An endless chain j, in which scraping plates 3 capable of scraping up particulate matter settling on the inclined plate λ, are attached at regular intervals is attached to a four-piece bucket 6.7 disposed above the settling tank l. Guided and equipped.

At this time, the endless chain j and the scraping plate J are connected via the adapter ja and the mounting plate 3a.

Sprocket≦ is the drive side, and one end GC of the rotating shaft t

is installed. Further, a guide 10 is provided between the sprocket nuts 6 and 7 above the water surface of the sedimentation tank to prevent the endless chain S from hanging below the water surface.

A vibrator/l, which is a source of repetitive shock, is attached to the back surface of the above-mentioned inclined plate, and fresh water supply ports 12 through which fresh water flows out onto the inclined plate λ are formed at appropriate intervals, and each supply port l
λ is connected to a water outlet (not shown) via a hose, etc. 0, 13 is a collected sand inlet, / is an over 70-chamber, /! F: i chain cover.

Next, the use of the massaging device of the above embodiment will be explained.

First, after filling fresh water to a predetermined water level, that is, to a height of over 70 chambers/1, the motor is started to drive the sprocket 6 and the endless chain 5 is run.

Next, the collected sand is continuously poured into the collected sand input port 13 and settling tank l.
When the fine sand with a high specific gravity floats on the water surface and is discharged from the over chamber to the outside of the tank, fine sand with a high specific gravity collects silt (mud). It settles and accumulates on the inclined plate in a state where it is contained. At this time, the fine sand containing silt that has settled and accumulated on the inclined plate λ is scraped up by the s11 raising plate 3 on the inclined plate 2, which is undergoing damped vibration due to repeated impacts (300 to 72000 Pm) from the back side. Moreover, fresh water flows out from fresh water supply ports/2 at appropriate intervals below the fine sand. Therefore, the fine sand is washed, that is, the muddy water in the fine sand is pushed upward by fresh water, the silt contained therein is removed, and clean fine sand is discharged from the upper end of the shaft swash plate. Incidentally, the inclined plate may have a damping loss movement, L, but the upper surface of the inclined plate -a has a low coefficient of friction less than Ql, so there is a large load on the chain drive! It is possible to efficiently lift up the settled fine sand while massaging it and transport it out of the settling tank without spraying it. In addition, muddy water is sequentially discharged from the over-puff nitrogen chamber to the outside of the tank.

Since the apparatus for massaging collected sand, etc. of the present invention has the above-described configuration, it has the following effects.

(1) An endless chain equipped with a scraping plate is installed on the inclined plate that forms the bottom of the sedimentation tank, the inclined plate is attenuated, and fresh water is drained from the inclined collection pipe. The mechanism enables continuous and efficient massaging. In addition, the massaging efficiency, that is, the silt removal rate is 1, and since the method uses clean water to push up the muddy water in the fine sand, it is better than normal massaging because there is no generation of mud due to abrasion of the fine sand. Furthermore, items with small specific gravity such as garbage, wood chips, and shellfish are removed.
