Description
Technical field
The utility model belongs to dust catcher parts, particularly relates to a kind of cyclone body dirt cup with wind-guiding spiral plate.
Background technology
Dirt cup is the dust collect plant of dust catcher, screen pack is provided with in conventional dust cup of dust collector, dust-contained airflow is to enter in dirt cup towards the direction of dirt cup sidewalls, rotate in dirt cup and form eddy airstream, the grit in air-flow is made to be thrown on the sidewall of dirt cup under the influence of centrifugal force, and then fall the bottom of dirt cup, reach the effect of cyclone dust removal; The filter core flow through again in dirt cup through the air-flow of cyclone dust removal is filtered again, and then discharges from air outlet.But owing to containing the trickle dust of particle in dust-contained airflow, with air motion, the bottom of dirt cup not easily can be fallen into by deadweight; Sometimes the dust fallen into bottom dirt cup also can hike up under the blowing compared with air blast, directly affects dust removing effects.
Summary of the invention
The purpose of this utility model is the technical scheme proposing a kind of cyclone body dirt cup with wind-guiding spiral plate, makes the dust in dirt cup stably be collected the bottom of dirt cup.
To achieve these goals, the technical solution of the utility model is: a kind of cyclone body dirt cup with wind-guiding spiral plate, described dirt cup is arranged on dust catcher, comprise dirt cup, dirt cup upper cover, filtration core, described dirt cup is provided with air inlet, the air intake direction of described air inlet towards dirt cup sidewall, the air-flow entering dirt cup is rotated in dirt cup, described dirt cup is covered with air outlet, described filtration core is arranged in dirt cup, the upper end of filtration core connects dust-accepting cup upper cover, the air outlet on the inner space filtration core of filtration core; Be provided with wind-guiding spiral plate in the lower end of filtration core, the hand of spiral of described wind-guiding spiral plate makes the air-flow in dirt cup move to the bottom of dirt cup in rotary course.
Further, described wind-guiding spiral plate is single-screw plate or double helix plate.
Further, the lead angle of described wind-guiding spiral plate is 10 ° ~ 20 °.
Further, described wind-guiding spiral plate outer is diametrically 0.6 times ~ 0.7 times of dirt cup internal diameter.
Further, the spiral number of turns of described wind-guiding spiral plate is no less than 1.2 circles.
The beneficial effects of the utility model are: make bottom the air flow direction dirt cup in dirt cup, and the wind speed reduced bottom dirt cup, dust in air-flow is guided to bottom dirt cup and moves, and is stably kept at bottom dirt cup, obviously can improve the dust removing effects of dust catcher.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart, is provided with single wind-guiding spiral plate;
Fig. 2 is the utility model shape assumption diagram;
Fig. 3 is the utility model structure chart being provided with two wind-guiding spiral plate.
Detailed description of the invention
As shown in Figure 1, Figure 2, a kind of cyclone body dirt cup with wind-guiding spiral plate, described dirt cup is arranged on dust catcher, comprise dirt cup 10, dirt cup upper cover 20, filtration core 30, described dirt cup is provided with air inlet 11, the air intake direction of described air inlet towards dirt cup sidewall, the air-flow entering dirt cup is rotated in dirt cup, described dirt cup is covered with air outlet 21, described filtration core is arranged in dirt cup, the upper end of filtration core connects dust-accepting cup upper cover, the air outlet on the inner space filtration core of filtration core; Be provided with wind-guiding spiral plate 40 in the lower end of filtration core, the hand of spiral of described wind-guiding spiral plate makes the air-flow in dirt cup move to the bottom of dirt cup in rotary course.
Described wind-guiding spiral plate is single-screw plate or double helix plate.
The lead angle α of wind-guiding spiral plate is 10 ° ~ 20 °.
The outer diameter d of wind-guiding spiral plate is 0.6 times ~ 0.7 times of dirt cup internal diameter.
The spiral number of turns of wind-guiding spiral plate is no less than 1.2 circles.
Embodiment one:
As Fig. 1, Fig. 2, a kind of cyclone body dirt cup with wind-guiding spiral plate, described dirt cup is arranged on dust catcher, comprise dirt cup 10, dirt cup upper cover 20, filtration core 30, the internal diameter of described dirt cup is 147mm, described dirt cup is provided with air inlet 11, the air intake direction of described air inlet is towards the sidewall of dirt cup, the air-flow 50 entering dirt cup is rotated clockwise (observing downwards from dirt cup upper cover direction) in dirt cup, described dirt cup is covered with air outlet 21, described filtration core is arranged in dirt cup, the upper end of filtration core connects dust-accepting cup upper cover, air outlet on the inner space filtration core of filtration core.
Be provided with wind-guiding spiral plate 40 in the lower end of filtration core, the hand of spiral of described wind-guiding spiral plate is dextrorotation, and wind-guiding spiral plate makes the air-flow in dirt cup move to the bottom of dirt cup in rotary course.
In the present embodiment, wind-guiding spiral plate is single-screw plate.
Lead angle α=15 ° of wind-guiding spiral plate.
Outer diameter d=the 87mm of wind-guiding spiral plate is 0.67 times of dirt cup internal diameter.
The spiral number of turns of wind-guiding spiral plate is 1.25 circles.
When dust catcher works, the air-flow 50 containing dust enters in dirt cup from the air inlet dirt cup, because the air intake direction of air inlet is towards the sidewall of dirt cup, the air-flow entering dirt cup is rotated clockwise in dirt cup, forms eddy airstream.Grit in air-flow is thrown on the sidewall of dirt cup under the influence of centrifugal force, and then falls the bottom of dirt cup, thus reaches the effect of cyclone dust removal.The filtration core flow through again in dirt cup through the air-flow of cyclone dust removal is filtered again, and then discharges from the air outlet being arranged on dirt cup upper cover.Wind-guiding spiral plate can make the swirling eddy of dirt cup bottom move bottom dirt cup, dust in the process rotated by the guide effect of gravity and spiral, can fast rotational to bottom, and can not up to run; Meanwhile, wind-guiding spiral plate can also weaken the flowing velocity of dirt cup lower stream of airflow, is conducive to ash fall and prevents dust from being blown afloat by air-flow, thus producing dust removing effects well.
Embodiment two:
As Fig. 3, a kind of cyclone body dirt cup with wind-guiding spiral plate, the present embodiment is that the one of embodiment one is improved.
In the present embodiment, described wind-guiding spiral plate is double helix plate.
In the dust catcher that power is larger, because the air-flow in dirt cup is comparatively strong, adopt the wind-guiding spiral plate of double helix plate can obtain better dust removing effects.
