Abstract

The utility model relates to a double-side suction-tube type dust filter; wherein, one side of a box body frame of the dust filter is equipped with a plurality of concentric circle annular filter cylinders, and two surfaces of each concentric circle annular filter cylinder are equipped with filter nets and filter cloths; a rotary main shaft is arranged at the center of the frame, and one end of the main shaft is equipped with a suction arm communicated with a dust exhaust hose; a plurality of suction pipes are extended from the suction arm, the front end of each suction pipe is provided with an up and down bent suction mouth, and the front part of each pipe is correspondingly arranged between two adjacent filter cylinders. When the air with dust enters the filter cylinder, the dust is withheld on the filter cloth, and then the rotary main shaft drives the suction mouth by the suction arm to make a circumference and reciprocating motion in order that the dust withheld on the filter cloth is sucked continuously, thereby finally achieving the objects of the dust collection and filter regeneration.

Description

Two-sided suction tube formula dirt catcher

The utility model content belongs to the environmental protection equipment technical field, relate to a kind of air filter, particularly a kind of can be used for, carry out secondary filter with the dryness dust, separate and the dust filtration device of removing fibre dust, and its product can be widely used in industries such as tobacco, weaving, papermaking and electric power.

Present particularly dust filtration equipment corresponding some defectives that all have on structural behaviour of textile enterprise of all kinds of manufacturing enterprises that are used for well known in the art, as domestic imitative Luwa that produces by introducing technology in recent years and LTG product all is two-stage filter dirt, one-level is removed the fibroid trifle in the world, cascade filtration is removed dust, and its equipment volume is big, maintenance difficult, space availability ratio are low; Though the imitative Luwa plate-type dedusting device and the honeycomb duster volume of Yin Jining is little afterwards, structure is motion structure complexity, Installation and Debugging difficulty, poor reliability especially; Although and other cartridge type dirt catcher structure is simple relatively, to filter owing to be single face, space availability ratio is low.

The purpose of this utility model is to overcome the defective that known technology exists, so provide a kind of simple in structure, volume is little, filter area is big, efficient is high, reliable operation and the two-sided easily suction tube formula of installation and maintenance dirt catcher.

The technical solution that adopts is so for achieving the above object: the two-sided suction tube formula dirt catcher that is provided has a hollow box body frame, on a side inwall of rack cabinet, the concentric ring-shaped filter cylinder that the multi-turn path length differs is housed, the said filter cylinder that respectively encloses constitutes by the filter screen frame that the two sides is provided with filter screen, is coated with filter cloth on filtering net surface; The main shaft tube of dress rotating spindle in the center position of frame is provided with, the suction arm of one pair and dust discharge flexible pipe UNICOM is housed away from an end of chassis wall at main shaft, inhale on the arm along horizontal UNICOM stretch set out many by one is long and the other is short configured in parallel and front end have the suction pipe that bends towards suction nozzle up and down, the front portion of every suction pipe is all corresponding stretches between the screen frame face that is located at two adjacent filter cylinders.In the course of work, after dust laden air entered filter cylinder, dust was trapped within on the filter cloth, and rotating spindle is done circumference and reciprocating motion by inhaling arm drive suction nozzle along filter cloth under motor-driven, the dust that is trapped on the filter cloth constantly is sucked away, finally reaches the purpose of dust collection filter cloth regeneration.

Below with reference to accompanying drawing the utility model content is described further.

Fig. 1 is the axial cutaway view of a specific embodiment structure of the utility model.

Fig. 2 is that the A of Fig. 1 is to view.

The schematic diagram of Fig. 3 cartridge unit structure.

Fig. 4 is that the B-B of Fig. 3 is to schematic diagram.

Referring to accompanying drawing, two-sided suction tube formula dirt catcher described in the utility model includes casing 6, frame 1, filter cylinder 2, suction pipe 3, inhales arm 4, dust discharge flexible pipe 5 and transmission mechanism.Transmission mechanism comprises reductor 14, belt pulley 15, main shaft tube 7, rotating spindle 8 and slide block axle 9, and main shaft tube 7 is fixed on frame 1 medium position, and main shaft 8 is positioned at main shaft tube 7, has left and right sides bipitch and slide block axle 9 to match on the main shaft 7.Filter cylinder 2 comprises filtration screen frame 11, filter cloth 12, filter cylinder support 13 and ring cowling 10, every circle filter cylinder 2 in the present embodiment structure is that filter element constitutes by 1/8th circular-arc filtration screen frames 11 that outside in eight is coated with filter cloth 12, and each filters screen frame 11 and is contained on frame 1 inwall by filter cylinder support 13 respectively and sealing is connected to the different integral circular shape tube of path length one by one.It is vertical and be contained in the end of main shaft 8 away from chassis wall to inhale arm 4 and main shaft 8, it communicates with dust discharge flexible pipe 5 by swivel joint, inhale on the arm 4 along horizontal UNICOM stretch set out many by one is long and the other is short configured in parallel and front end have the suction pipe 3 that bends towards suction nozzle up and down, the front portion of every suction pipe 3 is all corresponding stretches between the screen frame face that is located at two adjacent filter cylinders 2, the suction nozzle face that respectively bends towards on the suction pipe 3 is all parallel with filter cloth 12, makes the inside and outside filtering surface of each filter cylinder 2 that one is long and the other is short two suction nozzles in parallel are all arranged like this.

Compared with prior art, the utlity model has following advantage:

1, adopt two-sided cartridge type dust cage as filter element, compact conformation can make filter area obtain greatly Improve, also greatly increased the processing air quantity simultaneously, thereby reached the order of conserve space and raising filter efficiency ;

2, filter cylinder is combined into by eight identical filtration screen frames, filtrate can be seamed into the circular arc pocket and be enclosed within screen pack On the frame, make the replacing filter cloth convenient;

3, it is online that filtrate is coated on filtrate, and the pressure that filtrate bears bears by filtering screen frame, and filtrate can not be stretched because of the effect of air-flow and heave, and suction nozzle can be attached to filter material surface all the time, and pick-up performance is good.
