Abstract

The utility model relates to a dust removing and material discharging humidifying machine which comprises a machine frame, a belt wheel, a water spraying device, a barrel body, a shaft, and stirring teeth fixed on the shaft and arranged in a helical line shape at intervals. The whole machine is driven by the belt wheel to rotation through a driving motor. The utility model improves the stirring property of humidifying machines and ensures that as soon as entering the barrel body, material is stirred while the material is propelled, so that the humidifying property of humidifying machines is improved obviously. The utility model also changes straight teeth into skewed teeth and increase the treating capacity of powder dust humidification of humidifying machines.

Description

A kind of dust discharging humidifier

The utility model relates to a kind of improved dust discharging humidifier, belongs to the feedway technical field.

To the dust-like material, as in the industries such as boiler, metallurgy, kiln in the dry ash of formula dedusting handle, discharging or when carrying, fly upward in order to prevent dust, need with humidifier trickle in dry ash.Representative type single shaft spiral humidifier generally comprises frame, motor, belt, reductor, water injecting system, cylindrical shell, axle, and the feed auger and the mixing agitating auger that is fixed on back segment that are fixed on a leading portion.Motor via reducer drives the screw shaft rotation, and feed auger promotes the ash material, mixes that agitating auger then mixes in cylindrical shell, stirring, humidification, ash, mud, water is mixed stirring get.In order to improve mixing effect, Chinese patent 96209099 (name is called " a kind of improved single shaft spiral wetting stirrer ") discloses a kind of improved single shaft spiral humidifier, it stirs the continuous band spiral with the mixing of back segment and is modified into the stirrer gear of arranging by pitch, thereby material is stirred fully, improved the high speed running performance of humidifier.Yet this improvement is only established and to the mixing agitating auger of back segment, feed auger is still adopted general belt continuous helical.The discovery that is in operation because humidity of materials may be bigger, therefore easily forms bonding in operation process, be difficult for stirring, thereby influenced humidification treatment effect subsequently.

In addition, generally all be designed to square with the axis connection, also influenced the fltting speed of material owing to mix the stirrer gear of agitating auger.

The purpose of this utility model is to provide a kind of dust discharging humidifier of humidification better effects if.

The purpose of this utility model is achieved in that

A kind of dust discharging humidifier, it comprises frame 7, belt pulley 3, water injecting system 6, cylindrical shell 1, cylindrical shell 8, axle 5, whole device drives its rotation by drive motor through belt pulley, and its basic improvements are: all fixing stirrer gear 9 of pressing the pitch arrangement on the whole axle 5.

Above-mentioned dust humidifier, the bar number of described helix line is the 1-4 bar.

Above-mentioned dust humidifier, described stirrer gear 9 is column, strip shape body or other analogous shape.

Above-mentioned dust humidifier, the angle that is become between described stirrer gear 9 and axle 5 dextrad is the 75-90 degree.

Above-mentioned dust humidifier, the pitch of described helix line are 200-800MM, and the radical of stirrer gear is the 200-350 root.

Dust discharging humidifier according to the utility model making, owing to the leading portion spiral on the former humidification arbor is improved to the stirrer gear of arranging by pitch, thereby improved the whipping performance of leading portion, make material one enter cylindrical shell, promptly stir when being accompanied by propelling, owing to stir, the humidifying performance of humidifier also is significantly improved.In addition, after the stirrer gear of mixing agitating auger is modified into helical teeth, feed rate is accelerated, identical in other words feed rate can make a prompt drop low, thereby has improved the dust humidification process load of humidifier greatly.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Dust discharging humidifier described in the utility model comprises major parts such as frame 7, belt pulley 3, water injecting system 6, cylindrical shell 1, cylindrical shell 8, axle 5, and axle 5 is erected on the bearing seat 4, has fixed many stirrer gears of arranging by pitch 9 on axle 5.Whole device drives its rotation by drive motor through belt pulley 3, and particulate dust enters from inlet point 2, is advanced by stirrer gear and stirs, and water injecting system 6 makes dry ash moistening with the water spray down, then discharges from discharging opening 10.

Stirrer gear 9 can be designed as column, strip shape body or plates, or analogous shape, can select suitable profile of tooth according to equipment working condition.Axial spacing between the stirrer gear 9 is identical, and the axially spaced-apart of tooth root portion is identical in other words.The general design height of stirrer gear is identical, certainly, also can adopt not equidistant and not contour stirrer gear.The angle that is become between stirrer gear 9 and axle 5 dextrad is the 75-90 degree.

In order further to raise the efficiency, except that the structure of a helix line, also can adopt the structure of on axle 5, establishing rotation direction is identical, the space is uniform two pass, three roads or four road helix lines.

After adopting above-mentioned design, the utility model is particularly suitable for turning round under high speed, and the rotating speed of screw shaft 5 is 200-500 rev/min.

Water injecting system 6 is fixed in the position of cylindrical shell 8 left ends near inlet point 2, so that make humidity even by the abundant stirring of stirrer gear 9.If establish a plurality of nozzles, can be along cylindrical shell 8 separate configuration.

For large-scale wetting stirrer, because inlet amount and amount of water mismate, may be in cylindrical shell residual unnecessary water, bond, therefore, cylindrical shell 1 of the present utility model can be different with cylindrical shell 8 design-calculated diameters, is assembled by little cylindrical shell and large cylinder in other words conj.or perhaps, this both can make the inner end wall of joint form the obstructing surface of nature, can strengthen defeated material function again.
