Description

[Detailed description of the invention] This invention is mainly used in wet-type dust collectors that are used to collect dust generated during operation in agricultural facilities, either entirely or locally, and perform dust removal processing. This is related to a new dust collection water tank, and in a wet type dust collector that uses a shower to add moisture to the dust introduced into the dust removal chamber and collects the dust after it falls into the water tank, the inside of the drain port is A large number of scrapers are attached to the belt-like driving body of the catalyst pillar and move in contact with the stretched filter plate, the surface of the filter plate, the inner surface of the bottom wall of the water tank, and the inner surface of the guide wall to the sludge discharge port. The main feature is that the scraper is moved along the water surface with the tip of the scraper protruding above the water surface.

In the illustrated embodiment, a dust removal chamber 4, which has no ceiling or floor wall, is placed on top of a water tank 3 in which the front end wall 1 is tilted upward toward the front and the other panels are upright, and the dust removal chamber 4 is placed toward the rear. The edge 5 of this dust removal chamber 4 is slightly sunk below the water surface 6 to make it open, and the front of the top surface of the water tank 3 is an open water surface 7, and a net mist catcher 9 is installed on the open ceiling of the dust removal chamber 4. In addition, a pipe water shower 10 is installed below the mist catcher 9 in the dust removal chamber 4, and a shower 1 is installed inside the same.
At the same time, a regulation radar 11 with a large diameter in the peripheral part and a small diameter in the center is installed below the dust removal chamber 4 to distribute water through the water surface 6. An introduction header 12 is installed to discharge water diagonally toward the water tank 3, and the water from the water tank 3 is connected to the shower 10 through the drain port 13 of the water tank 3.
In addition, a filter plate 16 made of punched metal is placed rearward inside the rear end wall 2 of the water tank 3 so as to circulate the water through a circulation pump 14 and a filter device 15 connected to the water tank 3. Furthermore, a pair of overhanging plates 18, 18 are provided at the front end of the aquarium 3 to project forward, and between the overhanging plates 18, 18, the front end wall 1 of the aquarium 3 is extended. Reversing shafts 19 and 20 are provided inside the lower end of the filter plate 16, inside the lower end of the filter plate 16, and inside the upper end of the filter plate 16 in a direction perpendicular to the front-rear direction.
A belt-like body 21 of a catalyst pillar is wrapped around all of the belt-like bodies 9 and 20, and a large number of scrapers 22 are fixed to the outer peripheral surface of the belt-like body 21 at equal intervals parallel to the free rotation axis 19. One end of a specific free rotation shaft 19 provided across the shaft 18 is protruded outward, and a required drive machine (not shown) is connected to the protruding end,
With this specific idle shaft 19 as a drive shaft, the belt-like body 21 is circulated in an advancing direction with its lower side 23 moving from the rear to the front, and with this circulation, each scraper 22 is moved to the water surface of the water tank 3. Stir the part to submerge the dust floating on the water surface,
The sludge accumulated on the surface of the filter plate 16, the bottom wall 24 of the water tank 3, and the inner surface of the front end 1 (this acts as a sludge guide wall) is conveyed while scraping it off. The sludge is discharged from the sludge discharge port 25 through the chute 25 into the sludge box 26.

The present invention uses a filter installed inside the drain port in a wet type dust collector that uses a shower to add moisture to the dust introduced into the dust removal chamber and collects the dust after it falls into a water tank. A plate and a large number of scraping scrapers attached to a belt-like driving body of a catalyst pillar and moving in contact with the surface of the filter plate, the inner surface of the bottom wall of the water tank, and the inner surface of the guide wall to the sludge discharge port. Therefore, it goes without saying that the scraper attached to a single belt-like member is highly effective in efficiently and effectively preventing clogging of the filter plate and discharging sludge. Since the tip is moved along the water surface with the tip protruding above the water surface, it is possible to actively absorb water while transporting the dust floating on the water surface while keeping it floating. It is capable of actively settling and sinking by stirring, and has the excellent effect of efficiently collecting and eliminating in a short period of time.
