Abstract

PURPOSE:To collect a scraped-up substance with low water content, by a method wherein a scraping-up rotor is arranged on an upper spiral and a dehydrator apparatus equipped with a dehydrating tank and a vibrator is provided to said rotor. CONSTITUTION:A stock material such as sand containing mud thrown into a spiral classifier is classified into a scraped-up substance 13 such as sand with high water content and mud by a lower spiral on a shaft 2 and the scraped-up substance 13 is scraped up upwardly on an inclined tank. On the other hand, mud is mixed with water and precipitated to the bottom part of the tank. Sand scraped up by the lower spiral 3 is automatically sent into a dehydrating tank 8 with a vibrator 7 and water between particles of the scraped-up substance 13 is separated. The scraped-up substance 13 from which water is separated and which is densely pressed to the bottom part of the dehydrating tank 8 is scraped up by the partition plate of a rotor 10 and sent to a discharge port 16 through an upper spiral 4.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spiral classifier equipped with a dehydrating device for reducing the moisture content of fried oysters classified by the spiral classifier.

Conventional methods for dehydrating scraped materials include reducing the number of spiral revolutions and increasing the angle of inclination of the tank, but in the former case, the scraping capacity of the classifier decreases and is extremely unproductive. Met. In the latter case, the pool area and volume required for classification are small, which causes a deterioration in classification efficiency.

This invention solves the above-mentioned drawbacks, and by disposing a scraping funnel on the upper spiral and providing a dewatering device equipped with a dehydrating tank and a vibrator on the scraping funnel, the lower spiral of the spiral classifier is The scraped food with a high moisture content is mechanically dehydrated to collect the scraped food with a low water content.

The detailed description of this invention is as follows: Spiral classifier 1
A lower spiral 3 and an upper spiral 4 are attached to the spiral shaft 2.

The spiral shaft 2 is driven by a spiral drive device 5. 6 is an inclined tank with a built-in lower spiral, 7 is a vibrator, 8 is a dehydration tank, 9 is a casing of the upper spiral 4, 10 is a rotor that rotates on the outer circumference of the casing 9, and 11 is for rotating the rotor 10. This is a rotor drive device. 12 is the above-mentioned vibrator 7, dehydration tank 8,
The device constituted by the rotor 10 and the rotor drive device 11 is provided with a dewatering outlet 14 for discharging the water separated from the scraped food 13. 15 is fried oysters 13
16 is a scraped food discharge port for discharging the fried food 13.

Therefore, when a raw material such as sand containing mud is inputted into the spiral classifier 1 by an appropriate method, the raw material is transferred to the lower spiral 3 on the spiral shaft 2 driven by the spiral drive device 5, and the raw material has a high moisture content, e.g. The scraped materials 13 are classified into sand and other scraped materials 13 and mud and the like, and the scraped materials 13 are scraped upward on the inclined tank 6 by the lower spiral 3, while the mud and the like are mixed with water, and then the mud is deposited at the bottom of the tank 6. Precipitate. The scraped material 13 with a high moisture content scraped up by the lower spiral 3 is automatically sent to a dehydration tank 8 with a vibrator 7. The scraped food 13 fed into the dehydration tank 8 is first compacted at the bottom of the dehydration tank 8 by the vibration of the vibrator 7, and the water present between the particles of the scraped food 13 is separated. The separated water is discharged to the outside of the multi-tank through the dehydration outlet 14 of the dehydration tank 8.

Further, the compacted scraped material 13 is scraped up by the partition plate 15 of the rotor 10 shown in FIG. In the lowered state, the fried oysters 13 are discharged through the oysters outlet 16 and collected.

In this invention, after classification with a spiral classifier, the scraped food with a high moisture content can be dehydrated with a dehydrator and the scraped food with a moisture content of 1 can be collected, so when the scraped food is transported by a dump truck etc., water etc. can be poured onto the road. There is no risk of it spreading.

Furthermore, by using the device of the present invention, it is possible to increase the scraping rate and classification efficiency.
Since only a dehydrating device and the like are required, cost reduction can be expected.
