Description
Technical field
The utility model relates to a kind of knot screen, particularly relates to a kind of knot screen be applied on electrolytic aluminium factory hyper-dense phase conveying.
Background technology
Be aluminium oxide at the primary raw material of aluminum electrolysis industry hyper-dense phase conveying, in the aluminium oxide of discharging workshop section, be doped with a large amount of packaging bag litzendraht wires, the aluminium oxide with foreign material can result in blockage to feeding equipment, so need to remove foreign material.The equipment of the removing foreign material used on the market is at present vibratory sieves, vibratory sieve is used to there is following shortcoming: as long as collect on screen cloth due to foreign material packaging bag litzendraht wire, screen cloth will be caused to block, and the aluminium oxide cannot discharged by screen cloth can all be discharged from impurity discharging port.Therefore, on average per hourly just need shutdown to carry out labor cleaning's screen surface packaging bag litzendraht wire, also need the aluminium oxide of discharging from impurity discharging port again to collect in conveying equipment.In addition, adopt vibratory sieve manually to have high input, the airborne dust that field oxidation aluminium causes makes work under bad environment.
Summary of the invention
For above-mentioned prior art Problems existing; the utility model aims to provide a kind of aluminium oxide knot screen, and this knot screen input cost is low, dust removal rate is high, can extend the interval time of shutting down and carrying out labor cleaning's impurity; reduce labor intensity of operating staff, and improve work on the spot environment.
The utility model is achieved through the following technical solutions: a kind of aluminium oxide knot screen, it has a tubular trash extraction box, both sides, trash extraction box bottom are provided with charging aperture and discharging opening, trash extraction box bottom surrounding is provided with multiple equally distributed impurity removing hole, air supplying chamber is provided with bottom trash extraction box, boiling plate is accompanied between air supplying chamber and trash extraction box, be provided with charging aperture and the separated screen cloth of discharging opening in trash extraction box, screen cloth two ends are fixed on discharge outlet, trash extraction box top is provided with card, several exhaust filter bags uniform on card.
Be provided with deflector between described charging aperture and screen cloth, deflector height and width and screen cloth match, and deflector is fixed on charging aperture by stay pipe.
In described exhaust filter bag, support frame is installed.
Embedded access door is provided with in described trash extraction box top and screen cloth upper space.
The utility model solves aluminium oxide hyper-dense phase conveying needs frequent shutdown to carry out the problem such as labor cleaning's impurity and the bad cleaning of impurity, assorted clearly mouth can be opened every shutdown in 8 hours and carry out a labor cleaning, because clearing times reduces, the workload also corresponding minimizing of operating personnel; Under boiling plate gasification wind action, in trash extraction box, impurity is not be attached on screen cloth but loose being deposited in above boiling plate to clear up than being easier to, and reduces the labour intensity of operating personnel.
The utility model input cost is low, dust removal rate is high, can effective impurity in separation of oxygenated aluminium, and improves work on the spot environment.

Detailed description of the invention
hereinafter, with reference to the accompanying drawings of embodiment of the present utility model.
The aluminium oxide knot screen of the utility model embodiment, as Figure 1-4, this device has a tubular trash extraction box 4, both sides, trash extraction box bottom are provided with charging aperture 2 and discharging opening 3, trash extraction box bottom surrounding is provided with equally distributed six impurity removing holes 1, air supplying chamber 6 is provided with bottom trash extraction box, boiling plate 5 is accompanied between air supplying chamber and trash extraction box, screen cloth 7 is provided with in trash extraction box, charging aperture and discharging opening separate by screen cloth, screen cloth two ends are fixed on discharging opening, deflector 12 is provided with between charging aperture and screen cloth, deflector height is identical with screen cloth height, deflector width is corresponding with screen cloth diameter, deflector is fixed on charging aperture by stay pipe 11.Trash extraction box top is provided with card 8, card is uniformly distributed several exhaust filter bags 10, is provided with support frame 9, is provided with embedded access door 13 in trash extraction box top and screen cloth upper space in exhaust filter bag.
When aluminium oxide hyper-dense phase conveying, aluminium oxide knot screen is started working, aluminium oxide with foreign material such as packaging bag litzendraht wires enters from charging aperture 2, boiling plate 5 air feed to aluminium oxide to be suspended on boiling plate and to promote aluminium oxide to move to discharging opening 3 by air supplying chamber 6, the screen cloth 7 installed in trash extraction box 4 keeps apart charging aperture and discharging opening, trash extraction box charging aperture fixes deflector 12 by stay pipe 11, aluminium oxide with foreign material enters through deflector from import and is distributed in trash extraction box, by the filtration of screen cloth, foreign material are stayed in trash extraction box again, clean aluminium oxide is discharged from discharging opening by screen cloth, the exhaust filter bag 10 that trash extraction box top is arranged can meet the needs of trash extraction box exhaust.Trash extraction box surrounding is provided with 6 impurity removing holes 1, within average 8 hours, opens impurity removing hole cleaning once.Embedded access door 13 is for periodic maintenance and change the components such as screen cloth.
