Abstract
The utility model provides a carbamide packaging and dust collecting system which comprises a dust sucking opening that is connected to a main pipe through a branch pipe which is provided with a butterfly valve. The main pipe is communicated with a dust collector, a cloth bag dust collector is arranged in the dust collector and is communicated with one end of an induced duct, and the other end of the induced duct is connected with a fan motor. An air blowpipe is arranged inside the cloth bag dust collector, one end of the air blowpipe is connected with a back-blow air supply outside the cloth bag dust collector, and the back-blow air supply is connected with a pulse controller through a lead. The utility model has the advantages that the structure design is reasonable; carbamide dust is effectively prevented from flying outwards away from a packaging line so that the environment of a plant is protected; the rate of respiratory diseases suffered by the working staff in the plant is reduced; meanwhile, the corrosion of production apparatuses in the plant is relieved; the quality of finished carbamide products is not influenced during the filtration of the carbamide dust; and the filtered carbamide dust can be directly recovered.
Description
Technical field
The utility model relates to a kind of urea packaging system, specifically a kind of urea packing dust collecting system.
Background technology
The packaging process overwhelming majority in the urea production process adopts pipelining at present, and defeated material, screening and packing are all finished automatically by streamline.Though this packaging system is widely adopted, but also have a significant disadvantages: the carbamide dust that is mingled with in the urea product can fly away in course of conveying in a large number, both caused the waste of material, polluted working environment again, if long-term suction of the staff in the urea packing shop is suspended in airborne carbamide dust, the probability of suffering from breathing problem can increase greatly.Under certain condition, chemical reaction also can take place in carbamide dust, produces corrosive gas, and the equipment surface in the workshop is caused corrosion, has shortened the service life of urea production equipment.For solving the problem that carbamide dust flies away, the product that has has adopted the mode of wet dedusting, in the urea production streamline, spray equipment is set, carbamide dust is filtered, this method still can make urea product become moist with the situation of flying away that so can alleviate carbamide dust, needs just can pack after the further drying, the carbamide dust of discharging with spray liquid reclaims as if needing, and need import the granulation tower granulating and forming again.The product that has has adopted pneumatic concentration that urea product is filtered, its structure is that pneumatic separation device is installed at the material outlet place below defeated material belt, carbamide dust is sucked wherein, realize the effect of filtration, but this mode filter effect and not obvious, the vibratory sieve of urea packaging line, warehouse observation panel, and packing machine inlet etc. locate still to have carbamide dust and fly away.
Summary of the invention
The purpose of this utility model provides a kind of urea product drying that keeps, good filtration effect, and the carbamide dust that filters out can directly reclaim the urea packing dust collecting system of use.
The utility model for achieving the above object, be achieved through the following technical solutions: comprise suction port, suction port is connected to female pipe by sub-pipe, and sub-pipe is provided with butterfly valve, and female pipe communicates with dust arrester, dust arrester inside is provided with sack cleaner, sack cleaner communicates with an end of induced duct, and the other end of induced duct connects blower motor, and sack cleaner inside is provided with gas blow pipe, gas blow pipe is connected with sack cleaner blowback source of the gas outward, and the blowback source of the gas is connected with impulse controller by lead.Suction port be located at respectively the urea packaging line belt roller, feed bin observation, vibratory sieve, warehouse observation panel, and the packing machine inlet on.Sack cleaner in the dust arrester is provided with 1-8.Impulse controller is installed on the dust arrester outer wall.
Advantage of the present utility model is: reasonable in design; Can prevent effectively that carbamide dust from outwards flying away from packaging line, protect workshop condition; Reduced the probability that shop personnel suffer from breathing problem; Also alleviated simultaneously the situation that production equipment is corroded in the workshop; When being filtered, carbamide dust do not influence the quality of urea product; The carbamide dust that filters out can directly reclaim use.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model comprises suction port 1, suction port 1 is connected to female pipe 5 by child pipe 3, son pipe 3 is provided with butterfly valve 6, and the staff can set the suction air volume of suction port 1 by the aperture of regulating butterfly valve 6, and 1 urea product that sucks carbamide dust and can weight is not bigger of suction port is sucked wherein.Female pipe 5 communicates with dust arrester 8, dust arrester 8 inside are provided with sack cleaner 10, sack cleaner 10 communicates with an end of induced duct 12, the other end of induced duct 12 connects blower motor 14, sack cleaner 10 inside are provided with gas blow pipe 13, gas blow pipe 13 is connected with sack cleaner 10 blowback source of the gas 16 outward, and blowback source of the gas 16 is connected with impulse controller 15 by lead.Suction port 1 be located at respectively the urea packaging line belt roller 2, feed bin observation panel 4, vibratory sieve 7, warehouse observation panel 9, and packing machine inlet 11 on, to each place that dust flies away may take place and all filter, farthest reduce the amount of flying away of carbamide dust.Sack cleaner 10 in the dust arrester 8 is provided with 1-8, and the concrete quantity that adopts is determined according to actual conditions such as instrument size.Impulse controller 15 is installed on dust arrester 8 outer walls, is convenient for people to regulate at any time.
The utility model in use, blower motor 14 is opened, all produce negative pressure in induced duct 12, dust arrester 8, female pipe 5 and the son pipe 3, carbamide dust is sucked by suction port 1, enter dust arrester 8 along son pipe 3, female pipe 5, sack cleaner 10 in the dust arrester 8 filters carbamide dust, stays in the dust arrester 8, and the air after the filtration is discharged by blower motor 14 through induced duct 12.Blowback source of the gas 16 can regularly be blown into purge gas by gas blow pipe 13 in sack cleaner 10, sack cleaner 10 is shaken, and shakes to fall to being adsorbed on carbamide dust on sack cleaner 10 outer walls, prevents that sack cleaner 10 from being blocked by dust.The time that is blown into purge gas, the staff can regulate at any time by impulse controller 15 controls.
