The specific embodiment

Dust exhaust apparatus shown in Figure 1 is mainly cleaned by air exhauster 12 inhaled airs jointly by twice cascade, porous aggregate district and spray.Inhaled air is discharged atmosphere pass the cleaning of overflowing second cascade 19, the porous aggregate district 9 of formation after first cascade 18, second tank, the 8 dress water that overflow formation after first tank, 7 dress water are expired are expired and spraying in a direction indicated by the arrow successively in ventilation cavity 6 after.

Construction cavity 2 is arranged in the casing 1, workbench 3 is arranged in construction cavity 2, construction cavity 2 rear walls have screen 4 and wind scoop 5, the front end of ventilation cavity 6 is communicated with wind scoop 5, be arranged in ventilation cavity 6 first tank 7 and second tank 8 are arranged, overflow after first tank, 7 dress water are full and form first cascade 18, the contraction mouth 20 of wind scoop 5 is pressed close to first cascade 18, second tank 8 is arranged in water that first tank, 7 belows and first cascade 18 fall and takes in the airflow direction that second tank, 8, the second tanks, 8 dress water overflow second cascade, the 19 crosscut ventilation cavities 6 of formation after full.

Also be provided with porous aggregate district 9 in the ventilation cavity 6, there is spray nozzle 10 9 tops, porous aggregate district, water fender 11 is arranged on the spray nozzle 10, and the air exhauster 12 of ventilation cavity 6 ends makes the power that air-flow formation is advanced in the ventilation cavity 6, and makes the air of purification discharge atmosphere.

Porous aggregate district 9 can adopt article such as rough sand, crooked plastic straw, glass fiber as filler, allow air-flow from small duct, upwards flow, water reverse flow downwards from the duct in porous aggregate district 9 from spray nozzle 10 ejections makes air-flow and water fully cut and clean.The filler in porous aggregate district 9 is preferably used the plastic straw of bending and tube wall fold.

The mechanism of screen 4 as shown in Figure 3 and Figure 4, the stripe board 21 that is taken the shape of the letter U by some cross sections joins together and forms, form slit 22 between the adjacent bar plate and allow the air communication mistake, like this, at first sedimentation behind the wall of the dust collision stripe board 21 that the part granularity is bigger.More meaningfully, when this equipment was used for glaze spraying, the glaze raw material of sedimentation can directly be recycled.

Water fender 11 is preferably arranged on spray nozzle 10, allow air-flow flow out, can reduce the water smoke that is discharged in the atmosphere thus from the slit of 11 of ventilation cavity 6 and water fenders.

The low level portion that is positioned at ventilation cavity 6 is provided with funnel 13, and there is the cyclic water tank 14 of suitable volume funnel 13 belows, and screen pack 15 is arranged on the cyclic water tank 14.The water that first cascade 18, second cascade 19 and spray nozzle 10 fall flows back to cyclic water tank 14 after flowing to low level portion after funnel 13 filters through filter screen 15, supplied water to first tank 8 and spray nozzle 10 once more by pipeline and water pump.After the several times circulation, sludge concentration is higher in the recirculated water, material in recirculated water and the screen pack 15 can be derived, and dries the back and recycles.

In the ceramic industry, fragmentation, grinding, screening, dry body repaired biscuit, glaze spraying or loading of kiln dedusting in early stage are common technology, to be positioned on the workbench 3 by workpiece in the production and process, supply water to first tank 6 and spray nozzle 10, first tank 8 enters second tank 9, after waiting for that water in second tank 9 overflows, start air exhauster 12 and just can begin to produce.The dust that flies upward that produces in the operation enters ventilation cavity 6 from wind scoop 5, rushing at the cascade that first tank forms from the contraction mouth 20 of wind scoop 5 is cleaned for the first time, second cascade that second tank of flowing through again forms is cleaned once more, porous aggregate district 9 flows through, the water of top spray nozzle 10 ejection makes the porous aggregate district that enough flowing water be arranged, in the air hydrophilic dust porous aggregate district 9 be absorbed in the water after water fully contacts.

As depicted in figs. 1 and 2, air exhauster 12 rear portions connect a backflow ventilation shaft 16, the end of this backflow ventilation duct 16 is positioned at the front upper place of construction cavity 2, and be communicated with a horizontal pipeline 17, this horizontal pipeline 17 has the downward air vent of embarking on journey, make the air shunting of backflow and form air curtain in construction cavity 2 the place aheads, the air of barrier strip dust is diffused into outside the casing 1.

Fig. 4 illustrates another embodiment of the utility model, supply water with each the free feed pipe of two catch basins of the main distinction and the water pump of the embodiment of Fig. 1, form the cascade of the airflow direction of former and later two crosscut ventilation cavities, inhaled air is fully cleaned.
