Abstract

The utility model discloses a preliminary filter for air cleaner of gas engines, which comprises two sets of air inlet device and cover cap and a dust-removal fan. Wherein, the dust-removal fan is composed of blades and a blade holder. These blades are evenly arranged on an external circumference of the blade holder. An external end of the blade is straight and an internal end of the blade is bevel. A gap is positioned between the straight end and the bevel end of the blade. A pin shaft is arranged at an internal bottom of the cover cap. The blade holder is arranged on the pin shaft, thus rotating on the pin shaft. The utility model is capable of filtering air containing considerable sand and has a simple structure.

Description

A kind of first filter device of empty filter
Affiliated technical field
The utility model relates to a kind of annex of explosive motor, specifically a kind of first filter device of empty filter.
Background technique
The empty filter of explosive motor is one of its main accessories.Its effect is the grit in the filtered air, makes clean air enter the cylinder of motor, and the guarantee motor is normally transported biography.A kind of empty filter is arranged in the market, and it is made of first filter device and filtrating equipment.The main effect of filter device just is that dust in air is carried out just separating, and makes the bigger dust of particle be pulled out away from out this device because of centrifugal force.Just filter device is made up of two cover air-intakers and cover cap.Two cover air-intakers contain two interior cover and overcoats that diameter is different, and interior cover is positioned at overcoat central authorities, evenly are provided with in the same direction the polylith guide plate that tilts between two covers, retention gap between guide plate and the guide plate.Cover cap is the bowl shaped structure shape, is provided with the dust-discharging mouth on its side face.Cover cap is sleeved on two cover air-intakers.Just the working principle of filter device is: when explosive motor during in aspirating stroke, dust laden air enters in it the gap between guide plate, because in guide plate is obliquely installed between two covers, dust laden air rushes at the inwall of cover cap along the guide plate direction, inwall along cover cap moves then, and dust is dished out from the dust-discharging mouth of cover cap side face because of centrifugal force and inertial force, filters at the beginning of when dust laden air is obtained, just the air after the filter is inhaled in the minor diameter cover of two cover air-intakers, enters in the filtrating equipment then.In the bigger area of dust storm, airborne sand content is big, the big air of sand content is during through above-mentioned filter device just, because of the grains of sand heavier, thereby be difficult to the grains of sand to be dished out from the dust-discharging mouth of cover cap, so the grains of sand are difficult for separating from air, make to contain husky air and be drawn in the filtrating equipment by centrifugal force and inertial force, cause the air inlet turbidity test of motor poor, initial failures such as scuffing of cylinder bore can appear in motor.
The model utility content
The technical problems to be solved in the utility model provides a kind of first filter device of empty filter.This device not only can the big air of filtering sand content, and simple in structure.
In order to solve the problems of the technologies described above, the first filter device of a kind of empty filter of the utility model, it contains two cover air-intakers and cover cap, also contain the dedusting fan, this fan is made of blade, blade seat, and blade is distributed on the outer circumferential face of blade seat, the outer end of blade is that straight sheet, inner end are oblique sheet, be provided with breach between the straight sheet of blade and the oblique sheet, the interior central authorities of described cover cap are provided with bearing pin, and the blade seat of dedusting fan is arranged on this bearing pin and can rotates on this bearing pin.
The blade that is provided with on the described dedusting flabellum bar side face is three to six.
The oblique sheet of described dedusting fan leaf becomes 15 ° to 45 ° with the blade seat axis.
The tip portion of described dedusting fan leaf is provided with stiffening rib.
Blade, blade seat and the stiffening rib of described dedusting fan are injected into a whole.
Owing in cover cap, be provided with the dedusting fan; when explosive motor during in aspirating stroke; contain and suck in it the gap of husky air between guide plate; thereby containing in suction to rotate under the drive of husky air, the oblique sheet of dedusting fan leaf makes the rotation of dedusting fan; containing husky air is rushing at along the guide plate direction in the inwall process of cover cap; the straight leaf of rotation blade clashes into the airborne grains of sand; the enough energy of grains of sand acquisition are moved along the inwall of cover cap; under centrifugal force and inertial force effect, dish out, make to contain the husky airborne grains of sand and obtain filtering from the dust-discharging mouth of cover cap.Because a dedusting fan simple in structure only is set in cover cap, and its rotation relies on inhaled air to drive, and need not power, so this apparatus structure is simple.

Fig. 4 is the left view of figure.
1. cover caps among the figure, 2. dust-discharging mouth, 3. straight sheet, 4. breach, 5. blade, 6. oblique sheet, 7. blade seat, 8. guide plate, 9. in cover, 10. stiffening rib, 11. bearing pins, 12. overcoats.
Embodiment
Among Fig. 1, the first filter device of empty filter contains cover cap 1 and two cover air-intaker.Two cover air-intakers contain two interior cover 9 and overcoats 12 that diameter is different, and interior cover 9 is positioned at the central authorities of overcoat 12, evenly are provided with in the same direction the polylith guide plate 8 that tilts between two covers, retention gap between the guide plate.Cover cap 1 is the bowl shaped structure shape, is provided with dust-discharging mouth 2 on its side face, as depicted in figs. 1 and 2.The dedusting fan is made of blade 5 and blade seat 7, and blade 5 is distributed on the outer circumferential face of blade seat 7, and the outer end of blade 5 is that straight sheet 3, inner end are oblique sheet 6, is provided with breach 4 between the straight sheet 3 of blade 5 and the oblique sheet 6, as shown in Figure 3 and Figure 4.The interior central authorities of cover cap 1 are provided with bearing pin 11, and the blade seat 7 of dedusting fan is arranged on this bearing pin 11 and can rotates on this bearing pin 11, as shown in Figure 1.Cover cap 1 is sleeved on the overcoat 12 of two cover air-intakers, and makes them fixing together by bolt.For obtaining the effect of removing sand preferably, the blade 5 that is provided with on dedusting flabellum bar 7 side faces can be three to six.The oblique sheet 6 of dedusting fan leaf 5 becomes 15 ° to 45 ° with the axis of blade seat 7.For improving the intensity of blade 5, can be provided with stiffening rib 10 in the tip portion of blade 5.For reducing production costs, blade 5, blade seat 7 and the stiffening rib 10 of dedusting fan can be sent out and be injected into a whole.During work; contain the gap of husky air between polylith guide plate 8 and suck; thereby the oblique sheet 6 of dedusting fan leaf 5 rotates under the drive that sucks air and makes the rotation of dedusting fan; containing husky air is rushing at along guide plate 8 directions in the inwall process of cover cap 1; the airborne grains of sand of straight leaf 3 bumps of rotation; making the grains of sand obtain enough energy and move along the inwall of cover cap 1, dishes out in the dust-discharging mouth 2 from cover cap 1 under centrifugal force and inertial force effect, makes to contain the husky airborne grains of sand and obtain filtering.
