Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a wet dust collector with a sludge scraping conveyor, which is mainly used in agricultural facilities such as country elevators and rice centers.

[Prior art]

Conventionally, a wet dust collector equipped with a sludge scraping conveyor is disclosed in Japanese Utility Model Publication No. 61-19781, in which the dust introduced into the dust removal chamber is moistened by a shower and dropped into a water tank, where the dust is scraped and collected by a scraper. has been done.

[Problem to be solved by the invention]

The agricultural facilities mentioned above are characterized by a very high processing air volume and a large amount of dust collected by the dust collector, and the reality is that it takes a lot of effort to treat the sludge in the wet dust collector. It is.

The above-mentioned conventional wet dust collector is a type that combines a water tank and a sedimentation tank, and the capacity of this water tank is:
They were often designed with a capacity of 10 to 20 minutes of circulating water, requiring a very large water tank. For this reason, a sludge discharge device becomes expensive, and if a sludge discharge device is not provided, heavy labor is required to clean the aquarium after the season ends.

In addition, there are many problems with draining water from the aquarium, such as having to drain a large amount of water at once, requiring the use of multiple vacuum cars, and once draining water, it takes a long time to fill the aquarium. Ta.

It is an object of the present invention to provide a new wet type dust collector that can be implemented in a water tank with a capacity of about 1 to 2 minutes of the amount of circulating water and about 1/10 of the capacity of conventional methods. It is.

[Effect]

The water is used in circulation, and before it flows into the water tank, coarse garbage such as straw waste is filtered through a drainboard, and a portion of the circulating water from the water tank (1 to 10% of the amount of circulating water) is sent to the settling tank. Sufficient residence time in the settling gutter (30 to 60
1), and the settled sludge is discharged on a sludge scraping conveyor. Therefore, according to this method,
Dust in the 20 to 50 micron class, which was previously difficult to settle, can be settled and separated, and the water tank capacity is also small.
It is possible to easily clean the aquarium during the off-season, and the installation space can be reduced compared to the conventional method.

It is characterized by having a sludge depositing area 34 that receives coarse garbage from the coarse garbage fall port 16, sludge from the first sludge fall port 21, and sludge from the second sludge fall port 25, so that the amount of circulating water is 1 to 1. This is an excellent method that can completely achieve the initial objective of providing a new wet type dust collector that can be implemented in a water tank with a capacity of about 2 minutes and about 1/10 of the capacity of the conventional method. Not only is it effective, but it also makes it possible to settle and separate dust in the 20-50 micron class, which was difficult to settle in the past.It also makes it easier to clean the aquarium during the off-season, and is more effective than conventional methods.
