Description

The dust arrester of dust catcher

Technical field

The utility model relates to a kind of dust arrester of dust catcher.

Background technology

In the prior art, horizontal dust collector adopts simple cyclonic separation to carry out the filtration of dust in the dirt cup because volume ratio is less, structure is compact, and dust after filtering directly is collected in the bottom of dirt cup, but, do not carry out effective isolation between dust and the filter, therefore, in use these dusts can pollute filter again, cause filter shorter service life, and blocked by dust easily and lose filter effect.

Summary of the invention

The purpose of this utility model is: the dust arrester that a kind of dust catcher is provided, this device has the whirlwind air inlet in the leading section design of dirt cup, make between filter and the dirt cup and form cyclone chamber, and dust storage chamber is isolated in the periphery of dirt cup, design has the dust mouth on the dirt cup sidewall, thereby cyclone chamber and dust storage chamber are separated effectively, has not only improved separative efficiency and dust removing effects, and prolonged service life of filter, also can avoid the secondary pollution of air-out.

The technical solution of the utility model is: a kind of dust arrester of dust catcher, comprise the dirt cup and be installed in the interior filter of dirt cup, described dirt cup is provided with the whirlwind air inlet, form cyclone chamber between filter and the dirt cup, the periphery of dirt cup is provided with dust storage chamber, and the sidewall of dirt cup is provided with the dust mouth corresponding to dust storage chamber.

The further technical scheme of the utility model is: a kind of dust arrester of dust catcher, comprise the dirt cup and be installed in the interior filter of dirt cup, described dirt cup is provided with the whirlwind air inlet, form cyclone chamber between filter and the dirt cup, the periphery of dirt cup is provided with dust storage chamber, and the sidewall of dirt cup is provided with the dust mouth corresponding to dust storage chamber; Described whirlwind air inlet is arranged on the leading section of dirt cup; Described whirlwind air inlet is included in the whirlwind conduit that forms on the front end face of dirt cup, and the whirlwind conduit is provided with the whirlwind cover plate, and the whirlwind cover plate is provided with the jack that is connected with sweep-up pipe.

The more detailed technical scheme of the utility model is: a kind of dust arrester of dust catcher, comprise the dirt cup and be installed in the interior filter of dirt cup, described dirt cup is provided with the whirlwind air inlet, form cyclone chamber between filter and the dirt cup, the periphery of dirt cup is provided with dust storage chamber, and the sidewall of dirt cup is provided with the dust mouth corresponding to dust storage chamber; Described whirlwind air inlet is arranged on the leading section of dirt cup; Described whirlwind air inlet is included in the whirlwind conduit that forms on the front end face of dirt cup, and the whirlwind conduit is provided with the whirlwind cover plate, and the whirlwind cover plate is provided with the jack that is connected with sweep-up pipe; Described dust storage chamber is positioned at the middle part of dirt cup with upper/lower positions; One end of described filtering screen is adjacent with the whirlwind air inlet; The other end of described filtering screen is fixed in the rearward end of dirt cup.

In the technique scheme, described filter comprises the filtering screen on the air outlet of the rearward end that covers on the dirt cup, tubular sea handkerchief is installed in the filtering screen, or square extra large handkerchief is installed in the air-out passage at air outlet rear portion.

The utility model has the advantages that:

1. the utility model has the whirlwind air inlet in the leading section design of dirt cup, make between filter and the dirt cup and form cyclone chamber, and dust storage chamber is isolated in the periphery of dirt cup, design has the dust mouth on the dirt cup sidewall, thereby cyclone chamber and dust storage chamber are separated effectively, not only improve separative efficiency and dust removing effects, and prolonged the service life of filter, also can avoid the secondary pollution of air-out.

2. the characteristics that the utility model is less according to the horizontal dust collector volume ratio, structure is compact design cyclone chamber, have kept existing structure, have reduced production cost.
