Abstract
The utility model discloses a rotary-blowing-in-bag type blowback dust removal mechanism which comprises a magnetic valve, a main blowback pipe, a filter bag hole cage framework, an upper balance block, a branch blowback pipe, an upper bracket, a pattern plate, a rotary connector, a filter bag, a blowback gas jet pipe, a straight gas pipe, a lower balance block, a lower bracket and a filter bag bottom cage framework. According to the blowback dust removal mechanism, a solenoid valve is used to replace an electromagnetic pulse valve, so that the impact and the noise of a system are reduced; a rotary blowing frame is simple in innovative design structure and convenient to mount; by adjusting related parameters of the solenoid valve and compressed air, the blowing dust removal effect no matter a short bag or a long bag is consistent, stable and reliable, no impact is basically caused to the filter bag, the service life of the filter bag is prolonged, and the overhauling rate of a dust remover is greatly reduced. As the bag-type dust remover is divided into a plurality of box regions, the process is carried out by boxes one by one; the rest box regions normally work when one box region is used for removing dust, so that equipment can continuously and normally run.
Description
Technical field
The utility model belongs to bag dust abatement field, relates to specifically revolution spray bleed type anti-blow cleaning dust mechanism in a kind of bag.
Background technology
When sack cleaner is normally worked, dusty gas enters ash bucket by air inlet, due to the rapid expansion of gas volume, the thicker grit of a part falls into ash bucket because of the reason such as Action of Gravity Field or inertial impaction, and all the other grits rise and enter a bag chamber with air-flow, after filter bag filters, grit is trapped in the outside of filter bag, purified gas enters upper box by filter bag inside, then enters atmosphere by valve plate hole, exhaust outlet, thereby reaches the object of dedusting.Along with constantly carrying out of filtering, dust gathers more and more thick on filter bag surface, and dust remover resistance rises thereupon, in the time that resistance reaches certain value, the air quantity of dust pelletizing system significantly declines, and efficiency of dust collection declines, now must in time the dust gathering be removed, system could normal work.Wherein, pulse backblowing wind deashing is current most widely used purge mode.
Pulse backblowing wind purge mode is that filter bag is fixed on the porous plate (card) on dust collector box body top, filter bag inner side is provided with support cages bone, above every row's filter bag, there is an injection tube, spray-hole (mouth) is offered at center facing to each filter bag in injection tube, the other end of injection tube is connected with pulse-control system and the compressed air reservoir of the composition such as pulse valve, control valve, time according to the rules or Resistance Value, carry out pulse backblowing wind deashing by automatic control program.When deashing in a flash, in the time that high velocity jet air-flow passes through filter bag top Venturi tube, can induce times over the air that sprays tolerance, oppositely blow into together filter bag inside, form air wave, make filter bag produce from top to bottom expansion and impact shock sharply, the dust that filter bag outside is gathered is shaken off, and reaches the object of deashing.
But existing above-mentioned pulse backblowing wind purge mode also has following defect: the factors the such as whether quality of deashing effect and Venturi tube structure and jet-core region line and filter bag center line be consistent are relevant, and parts machining precision and installation accuracy are had relatively high expectations; When filter bag is longer, shock strength can weaken to bag bottom, can not obtain consistent ash-removal effect uniformly from top to bottom; Pulse shock makes stretched and relaxed easy fatigue damage of filter bag, also can make filter bag and cage ostosis friction infringement, greatly reduces life of bag filter.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides revolution spray bleed type anti-blow cleaning dust mechanism in a kind of bag, can realize brand-new and reliable ash-removal effect unanimous between the higher and lower levels, simultaneously to filter bag substantially without impact.
The utility model for the technical scheme that solves its technical problem and adopt is:
Revolution spray bleed type anti-blow cleaning dust mechanism in a kind of bag, comprise cage bone at the bottom of magnetic valve, back-blowing supervisor, filter pocket mouths cage bone, upper balance weight, back-blowing arm, upper bracket, card, swivel joint, filter bag, blowback air jet pipe, straight tracheae, lower balance weight, lower carriage and filter bag
Described filter bag fixed cover is located at the bottom of described filter pocket mouths cage bone and filter bag outside the osteoplastic cage skeleton of cage, and described filter pocket mouths cage bone is fixed on described card; Described upper bracket is fixed on described filter pocket mouths cage bone, at the bottom of described lower carriage is placed in described filter bag bottom and is fixed on described filter bag on cage bone;
The top stiff end of described swivel joint is fixed on described upper bracket, and the rotatable end of the bottom of described swivel joint is fixedly connected with described upper balance weight, and the lower end of described lower balance weight is rotatably inserted on described lower carriage; Described straight tracheae and blowback air jet pipe are arranged at respectively between described upper balance weight and lower balance weight, and two mouths of pipe of this straight tracheae and blowback air jet pipe corresponding connection respectively, on described blowback air jet pipe, are provided with row's back-blowing fumarole along its axial direction;
The lower end of described back-blowing arm is connected on the top stiff end of described swivel joint, and it is upper that the upper end of described back-blowing arm is connected to described back-blowing supervisor, and described magnetic valve is located on this back-blowing supervisor.
As further improvement of the utility model, the plane of the axis place plane of described back-blowing fumarole and described blowback air jet pipe and blowback air jet pipe axis and described straight tracheae axis composition forms angle.
As further improvement of the utility model, described angle is 70～80 °.
As further improvement of the utility model, long 6～7 meters of described filter bag, external diameter 160～165mm.
As further improvement of the utility model, described blowback air jet pipe is identical with the external diameter of straight tracheae, is 20～25mm, and the centre-to-centre spacing of this blowback air jet pipe and straight tracheae is 60～70mm.
As further improvement of the utility model, described back-blowing fumarole diameter is 4～6mm, and this back-blowing fumarole number is 100～150.
As further improvement of the utility model, the lower end of described lower balance weight is rotatably inserted on described lower carriage by bearing.
The beneficial effects of the utility model are: replace electromagnetic impulse valve with magnetic valve the impact of system and noise are reduced; The innovative design of rotary blowing frame is simple in structure, easy for installation, by adjusting magnetic valve and compressed-air actuated relevant parameter, short bag or long its jetting deashing effect of bag are all by unanimous between the higher and lower levels steadily reliable, to filter bag substantially without impact, improve life of bag filter, greatly reduced deduster maintenance rate.Because sack cleaner equipment is divided into several case districts, so said process is undertaken by case, Yi Gexiang district is in the time of deashing, and all the other case districts, still in normal work, have ensured the continuous normal operation of equipment.
