Description
Technical Field
The utility model belongs to the technical field of the fan, specifically an axial fan for drying-machine.
Background
The fan has wide application, including a centrifugal fan and an axial flow fan, and only needs to ensure the air quantity on a dryer because the requirement on the air pressure is not high, and the common fan is the axial flow fan.
The existing dryer is commonly used for drying grains and the like, the dryer sucks air through the axial flow fan to increase the air flow speed to rapidly dry articles in the dryer, and the grains in the dryer have impurities, so that the impurities in the grains can be continuously sucked into the air during drying, and the quality of external air is poor. And the impurities continuously strike the blades of the fan, so that the blades are quickly abraded, and the service life is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is not enough to prior art, provide an axial fan for drying-machine, this axial fan can detach the impurity in the grain, effectively reduces the impurity in the grain and pervades in the air, effectively improves the outside air quality of drying-machine during operation to extension axial fan's life.
In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the utility model provides an axial fan for drying-machine, includes the cylindric casing, be provided with first motor and first fan in the casing, casing one side is provided with the aviation baffle, the casing opposite side is provided with spiral channel, spiral channel external diameter side is connected with the dust removal passageway, the dust removal passageway is connected with the passageway that induced drafts, be equipped with second motor and second fan in the passageway that induced drafts, the passageway exit that induced drafts is provided with the impurity filter-tank that is used for storing impurity, be provided with the filter screen that is used for filtering impurity in the impurity filter-tank. This axial fan passes through the gaseous follow spiral channel of suction in the drying-machine when induced drafting, impurity in the gaseous through spiral channel can remove along the outer wall of spiral channel's external diameter side because of the effect of centrifugal force, impurity is by the passageway suction of induced drafting when removing induced draft passageway department, stay in the impurity filter-tank after impurity in the gaseous that comes out from the passageway of induced drafting is filtered by the filter screen, thereby impurity in the reduction grain is diffused in the air, effectively improve the outside air quality of drying-machine during operation, and extension axial fan's life.
In the above technical scheme, preferably, the impurity filter tank is internally provided with liquid for adhering impurities, and the outlet of the air suction channel extends into the liquid level of the liquid. Impurities in the gas can be adhered to the liquid in the filter tank, and small particle impurities are prevented from passing through the filter screen.
Among the above-mentioned technical scheme, preferably, the dust removal passageway with the junction of the passageway that induced drafts is provided with the dust board, the dust board is followed the passageway that induced drafts to the dust removal passageway extends, be provided with a plurality of ventilation holes on the dust board. The dust blocking plate is arranged to guide and block impurities, so that the impurities can smoothly enter the air suction channel.
Among the above-mentioned technical scheme, preferably, the impurity filter tank with the casing passes through the bolt and can dismantle the connection, adopts this structure to make the dismouting that the reservoir can be convenient.
Compared with the prior art, the utility model, following beneficial effect has: this axial fan passes through the gaseous follow spiral channel of suction in the drying-machine when induced drafting, impurity in the gaseous through spiral channel can remove along the outer wall of spiral channel's external diameter side because of the effect of centrifugal force, impurity is by the passageway suction of induced drafting when removing induced draft passageway department, stay in the impurity filter-tank after impurity in the gaseous that comes out from the passageway of induced drafting is filtered by the filter screen, thereby impurity in the reduction grain is diffused in the air, effectively improve the outside air quality of drying-machine during operation, and extension axial fan's life.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1, an axial fan for drying-machine, including cylindric casing 1, be provided with first motor 2 and first fan 3 in the casing 1, casing 1 one side is provided with aviation baffle 4, casing 1 opposite side is provided with spiral channel 5, spiral channel 5 can be through the welding of spiral shape board in cylindric casing 1, cut apart into spiral channel with cylindric casing 1, also can directly make the pipeline spiral and then install in cylindric casing 1, spiral channel 5 external diameter side is connected with dust removal channel 6, dust removal channel 6 is connected with induced draft channel 7, be equipped with second motor 8 and second fan 9 in the induced draft channel 7, induced draft channel 7 exit is provided with the impurity filter tank 10 that is used for storing impurity. In this embodiment, impurity filter tank 10 passes through the bolt and can dismantle the connection on cylindric casing 1, and the both sides of impurity filter tank 10 are equipped with the gas outlet, are equipped with filter screen 11 in the impurity filter tank 10 that is located the gas outlet below, and the passageway 7 that induced drafts passes filter screen 11 and the exit is located the below of filter screen 11, is provided with the liquid that is used for the adhesion impurity in the impurity filter tank 10, and the liquid level of liquid is stretched into in the passageway 7 export that induced drafts.
This axial fan passes through the gaseous follow spiral duct 5 of suction in the drying-machine when induced drafting, impurity in the gaseous of spiral duct 5 can remove along the outer wall of spiral duct 5's external diameter side because of the effect of centrifugal force, impurity is by induced draft 7 suction when removing induced draft 7 department, stay in impurity filter-tank 10 after impurity in the gaseous of following induced draft 7 out is filtered by filter screen 11 and liquid, thereby it is in the air to reduce the impurity diffusion in the grain, effectively improve the outside air quality of drying-machine during operation, and extension axial fan's life.
In order to obtain better impurity removal effect, the junction of the dust removal channel 6 and the air suction channel 7 is provided with a dust baffle plate 12, the dust baffle plate 12 extends from the air suction channel 7 to the dust removal channel 6, and a plurality of uniformly distributed ventilation holes are formed in the dust baffle plate 12.
