Be a rectangle above the cross section of described expansion chamber and bag-type dusting room, below is back taper, is circular arc bottom back taper.The design of bottom back taper and circular arc, can utilize the Action of Gravity Field of dust self automatically to collect on the running route of auger, without the need to providing power in addition.
Described dust-filtering plate is provided with some through holes, and the dust-filtering plate used with group, on the direction of expansion chamber to bag-type dusting room, dust-filtering plate aperture reduces successively.According to the dust-filtering plate of the dustiness design different pore size in dust-containing tail gas, dust-filtering plate is made to have higher effect of settling under nonclogging prerequisite.
Described dust-filtering plate inside is provided with ultrasonic vibrator.Through long sedimentation, easy sedimentating dust on dust-filtering plate, if shut down cleaning can cause no small loss, installing ultrasonic vibrator can carry out Automatic clearance to dust-filtering plate, extends the service life of dust-filtering plate.
Electrostatic precipitation rod is installed in described expansion chamber.Dusty gas is electrically isolated through high-voltage electrostatic field, and on grit and anion Binding protein after negative electricity, trend anode surface electric discharge and depositing, has efficiency of dust collection high, dedusting particle diameter wide ranges, the simple feature of structure.
The beneficial effects of the utility model are:
(1) the utility model solves in chemical fertilizer production process, the problem that inside air Dust Capacity is serious;
(2) the utility model improves production environment, decreases the number of times of hygienic cleaning, has saved labour, alleviates the labour intensity of workman and ensure that workman's is healthy and safe;
(3) the utility model has reclaimed and can return as raw material the dust added in a large number, reduces production cost.

Detailed description of the invention:
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of chemical fertilizer production dust arrester, comprises expansion chamber 1, auger 2, bag-type dusting room 4 and air-introduced machine 5; Top on the left of expansion chamber 1 is provided with the air intake 8 be connected with dust-containing tail gas pipeline, dust-containing tail gas enters expansion chamber 1 and sedimentation occurs, dust after sedimentation falls the bottom of expansion chamber 1, expansion chamber 1 inside is communicated with bag-type dusting room 4, be eliminated by the sedimentation major part dust of expansion chamber 1, after entering bag-type dusting room 4, dust again carries out sedimentation and falls the bottom of bag-type dusting room 4.Auger 2 be positioned at expansion chamber 1 and bag-type dusting room 4 below and through expansion chamber 1 and bag-type dusting room 4, the tail end of expansion chamber 1 and bag-type dusting room 4 is respectively equipped with dedust port 3, by the rotation of auger 2, helical blade on auger 2 promotes dust and arrives dedust port 3, dedust port 3 is connected with waste recovery case, and dust falls into ash can.The outlet of bag-type dusting room 4 is connected with air-introduced machine 5 by ventilating duct 7, for dust-containing tail gas provides power.Dust-containing tail gas finally after process is discharged by exhaust duct 6.
As shown in Figure 2, expansion chamber 1 comprises the first expansion chamber 11, second expansion chamber 13, the 3rd expansion chamber 14 and dust-filtering plate 12, is divided into three grades, and is separated by dust-filtering plate 12.Expansion chamber 1 is cuboid, and inside is cavity structure, is from left to right followed successively by the first expansion chamber 11, second expansion chamber 13 and the 3rd expansion chamber 14.Two adjacent expansion chamber 1 dust-filtering plates 12 separate.With the dust-filtering plate 12 that group uses, on the direction of expansion chamber to bag-type dusting room, dust-filtering plate aperture reduces successively, after dust-containing tail gas enters expansion chamber 1, successively by first, second and third expansion chamber.Through the stop of dust-filtering plate 12, most dust is made to fall the bottom of expansion chamber 1.
As one improvement, install electrostatic precipitation rod in expansion chamber 1, the dust in dust-containing tail gas easily produces electrostatic due to rapid movement and high temperature, is not easy sedimentation, and after installation electrostatic precipitation rod, the electrical counteract of meeting and dust, accelerates the sedimentation of dust.
Improve as one, ultrasonic vibrator is installed in dust-filtering plate 12 inside, purifies in dust-containing tail gas process at dust-filtering plate 12, ultrasonic vibrator shakes, reduce the accumulation of dust on dust-filtering plate 12, increase the service life of dust-filtering plate 12, extend the life cycle of dust-filtering plate 12.
As shown in Figure 3, bag-type dusting room 4 is divided into upper and lower two parts, is respectively sack cleaner 42 and bag and sinks room 41.Dust-containing tail gas enters bag-type dusting room 4 after the filtration of expansion chamber 1, in bag sinks room 41, carry out of short duration depositing dust, enters sack cleaner 42 and carries out further dedusting.
As shown in Figure 4, be a rectangle above the cross section of expansion chamber 1 and bag-type dusting room 4, below is back taper, is circular arc bottom back taper, just coordinates with auger 2 and installs.The dust that dust-containing tail gas settles down falls the bottom of expansion chamber 1 and bag-type dusting room 4, then slips into circular arc powder groove through the bottom surface of back taper, is promoted the dedust port 3 of powder motion by the rotation of auger 2.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
