Description

The drum-type combined dust remover

The utility model is a kind of air filter unit, is that a kind of spinning and weaving workshop that is used for carries out the drum-type combined dust remover that fibre dust filters, separates, collects, removes specifically.

At present, though the air filter unit kind that China textile enterprise uses is many, backward in technique, in the last few years, some textile mills introduce foreign products one after another, and to meet the needs of production, introducing maximum is the internal-suction type deduster of German LTG company and the plate-type dedusting device of Switzerland Luo Wa company.These two kinds of equipment all are two-stage filter dirt, the airborne fibroid trifle in the world of the main elimination of the first order, the airborne dust of the main elimination in the second level.The internal-suction type deduster first order dirt catcher of Germany LTG company is made up of inlet box, mixed bellows, disk filter screen, rotation suction nozzle by the disk filtering net surface siphons away the fibroid trifle in the world, second level dirt catcher is a great circle cylindricality dust cage, is furnished with the filtrate of Chalk-dust filtering on the face of cylinder.Two suction nozzles are housed in the dust cage, and suction nozzle is close to dust cage filtrate inwall, under transmission mechanism drives, can move back and forth vertically, and can turn round around axis simultaneously.Enter the dust cage inner chamber through the air that still contains dust after the one-level filtration, under the suction of blower fan, air is taken out outside cage outside dust cage, and dust then adheres to cage filtrate inwall, suction nozzle siphons away dust in moving back and forth and turning round, and is sent to outer dust arrester of cage or cyclone separator and separates removing.This deduster because suction nozzle and transmission mechanism all are contained in the dust cage inner chamber, have not only occupied big quantity space in the dust cage, and has made entire equipment bulky, complex structure, and the maintenance difficulty, filter area is restricted; The plate-type dedusting device first order dirt catcher and the LGTG internal-suction type structure of Switzerland Luo Wa company are basic identical, second level dirt catcher is a kind of plank frame, it is equipped with by one, and machinery is inhaled the casing of arm and the vertical Baltimore groove lattice of a plurality of thin-and-longs are formed, groove lattice two wall cloths have filtering material, under transmission mechanism drives, can inhale arm as the belt-type machinery that vertical and horizontal move, it is a long box of narrow shape, the belt that has suction inlet turns round in box, the width that this machinery is inhaled arm is slightly less than the groove lattice, and when the suction arm entered the groove lattice successively, the belt that has suction inlet was just in time in the face of groove lattice filtrate inwall, belt is in revolution, and the dust that will be sticked on the filtrate inwall by suction inlet siphons away.Though this deduster volume is less, belt-type machinery is inhaled the arm configuration complexity, and machining accuracy and installation accuracy require very high, enters also easy jam behind the groove lattice, and belt part is easily extended, skids, is out of shape and leaks out, and influences the air draught ability.

The purpose of this utility model is to provide that a kind of volume is little, filter area is big, simple in structure, maintenance capacity is few, the drum-type combined dust remover of reliable operation.

The technical solution of the utility model is: this deduster is by inlet box, shell, the one-level dirt catcher, the secondary dirt catcher, sealing ring, two suction nozzles and transmission mechanism are formed, one-level dirt catcher and secondary dirt catcher are cylindrical, connect into an all-in-one-piece cylinder by bolt, this cylinder by a plurality of carrying roller rollers with the cylinder rest on rolling stand, making cylinder not produce warp-wise moves, the one-level dirt catcher of drum front end places in the inlet box, be provided with anti-thrust bearing at the cylinder tail end, prevent to make moving axially of cylinder generation because of the blower fan draft, the circumferential surface of one-level dirt catcher is provided with dirt filtrating screen, be fixed with dust absorption nozzle in inlet box one side, this suction nozzle mouth is near the dirt filtrating screen face, be provided with multilayer concentric annular dust cage in the secondary dirt catcher, be equipped with a dust absorption nozzle that is fixed on the support in each dust cage, two kinds of suction nozzles all are access to outside the machine with pipeline, collect respectively, remove.Be provided with continuous drum gear on the periphery of secondary dirt catcher tail end, be provided with motor and decelerator at outer casing bottom, the power of this motor drives rolling bearing through decelerator by meshing gear, drives whole cylinder slow rotation.Be attached to the online fiber trifle in the world of dirt on the one-level dirt catcher with fixed attention and siphoned away the dust that sticks on the multilayer concentric annular dust cage dirt catcher filtrate inwall by a fixing suction nozzle continuously and siphoned away continuously, reach the purpose that purifies air by another fixing suction nozzle.

The utility model compared with prior art has following advantage:

1, the whole cylinder that has adopted cylindrical one-level dirt catcher and multilayer concentric annular dust cage secondary dirt catcher to be combined into has made full use of the space, has shortened the length of dust cage, has guaranteed filter area, makes whole deduster volume-diminished.Its volume less than LTG company internal-suction type deduster half, Luo Wa company plate-type dedusting device 2/3rds.And its dust removal and filtration ability big by 50% than above-mentioned company, and under the equal volume situation, can increase filter area by the number of plies that increases annular dust cage, do not need to enlarge the appearance and size of complete machine.2, adopted cylinder rotation, the fixing mode of not moving of suction nozzle, moved back and forth simultaneously and the suction nozzle transmission mechanism of gyration thereby cancelled, whole deduster simplified the structure, maintenance capacity is few.Be provided with complicated moving link and electric equipment in the dust laden air in drum cavity, the transmission mechanism of cylinder is all in the work of clean place, and the performance of therefore anti-fire alarm, antiseize is good, safe and reliable to operation.

Fig. 1 is that the A-A cross-sectional view of Fig. 2 is a front view,

Fig. 2 is that the B-B cross-sectional view of Fig. 1 is a vertical view,
