The specific embodiment

In the embodiment shown in fig. 1, the twin shaft output motor is fixed on the support that is in Venturi tube purifier trunnion position, and an axle head is installed impeller, and an other axle head is installed the utility model.Motor shaft passes the utility model center circle pore, and steady pin snaps in pipe upper end groove on the motor shaft, and the motor shaft end is fixed the utility model with round nut.During work, motor shaft drives blade and the utility model rotates together.

Rotary blade produces negative pressure, and under suction function, oil smoke enters air compartment vertically, vertically impinges upon on the horizontal high speed rotation filter plate.Because the filter plate radial dimension is big, area is big, and the soot particles quantity that bump took place in the unit interval is big.Filter plate has good thermal conductivity, and the kinergety of particulate is absorbed rapidly by filter plate, and oil smoke condenses into fine drop, and on filter plate, the realization air separates with the oil smoke material.

Motion filter plate and oil smoke form relative motion, and subparticle moves along wall with flue gas stream, produces wall attachment effect.The draught head of rotation formation impels more flue gas and filter plate friction at a high speed, contact, and more collision opportunity takes place in more particles, and the soot particles condensation number increases.

Parallel filter plate laterally rotates cutting refinement oil smoke at a high speed, and the surface contacts repeatedly with flue gas, repeated friction, has quite increased collision, contact, the condensation area of oil smoke.Because oil smoke is cut refinement, be divided into various tiny processing units, make oil smoke in each junior unit all be able to filter plate fully, contact repeatedly, the collision of soot particles, contact, condensation, adhere to settlement action and fully carry out, oil smoke condensation is deposited on the filter plate surface.

Purify bell mouth shape in the air compartment inwall, diameter little lower diameter in middle part is big, and the air-flow that is scanned driven rotary by filter plate is when rotating up motion, and its swing-around trajectory diminishes and the centrifugal force increase, hindered by inner wall shape increases, and the big mass particles of result is trapped and no longer continues row with air-flow.

Condensing droplet is thrown toward the air chamber wall under the rotating centrifugal effect, the air chamber bottom is provided with long-pending oily deflector structure, and drop flows in the annular oil collection box along oil guide plate under the gravity effect.The long-pending oil of cigarette machine, incrustation not exempt to clean.

Thoroughly solve the pollution of grease to body, parts, solve the accumulation and the blockage problem of grease, be convenient to clean, maintenance workload is little.

In the embodiment shown in fig. 3, the oil smoke filter plate is the spiral shape structure, 3 thin thickness, and the banded filter that radial dimension is big is welded on the pipe with very little lift angle dextrorotation coiling.During work, 3 filter plates are cut apart flue gas continuously, and the cutting unit is littler, more even.The very little oil smoke of cutting unit along the structure that filter plate spirals and rises, is that very thin one deck is attached to move along wall when rising.In the draught head of rotation formation at a high speed and the effect of molecular attraction, almost completely adhere on the object plane, the soot particles that adhesion is big is just easier is caught condensation by the solid object plane, and deposits with air separation, and wall attachment effect strengthens.The cutting unit is more little, even more, and the length of hurricane band is long more, and attached wall flue gas layer is just thin more, and flue gas is just abundant more with contacting of filter plate surface, the collision of soot particles, adhere to, condensation, deposition be just more thorough, clean-up effect is just good more.
