Abstract

The utility model discloses an improved VAS (vessel analysis system) air classifier comprising a box body (1), an upper induced draft pipeline (2), a lower induced draft pipeline (3), wind power adjusting plates (4) and a net cage (5), wherein a material inlet (6) is arranged on the side wall of the middle-upper part of the box body (1), the induced draft pipeline (2) is arranged at the top of the box body, two wind power adjusting plates (4) are oppositely arranged on the bottom of the box body (1) by a screw rod, a blanking port (7) is formed by the two wind power adjusting plates (4), the net cage (5) is arranged below the box (1), and the lower induced draft pipeline (3) is arranged at the bottom of the net cage (5). In the improved VAS air classifier, smashed tobacco shreds are separated from stems by the gravity wind principle, heavier stems drop down and are sucked into dust removal chamber, the lighter tobacco shreds are sucked upwards, return to and are mixed into the tobacco shreds, so that the air classifier plays the roles of lowering cost, improving efficiency, and guaranteeing the cleanness of production fields.

Description

Modified VAS air classifier

Technical field

The utility model relates to cigarette machine, is specifically related to the modified VAS air classifier in the dry exit of leaf silk.

Background technology

Known, after the VAS screening, eliminate a large amount of stalks and sign and broken pipe tobacco, in line with the principle of cost efficiency and the neat and tidy of assurance production scene, it must be moved to the elsewhere and deal with in addition.Method in the past is manually will sieve thing to shed carry out postsearch screening on groove is shaken in screening, selecting some more complete pipe tobaccos returns and mixes, but large-scale industrial production is not satisfied in so artificial separation, exists consuming time, consumption simultaneously and manually and easily produces problem such as environmental pollution.

Summary of the invention

The purpose of this utility model is: a kind of modified VAS air classifier is provided, and simple in structure, with low cost, easy to operate, safeguard easily the dust removal rate height.

Technical solution of the present utility model is: this air classifier comprises casing, last air-suction duct, following air-suction duct, wind-force adjustable plate and net cage, establish charging aperture on the middle and upper part sidewall of casing, air-suction duct is installed at the top of casing, two wind-force adjustable plates are installed through screw mandrel in the bottom of casing, form blanking port by two wind-force adjustable plates, net cage is installed below casing, and air-suction duct is down installed in the bottom of net cage.

Wherein, wherein on the sidewall observation window is installed at casing.

During work, the mixture that pipe tobacco and stalk are signed falls in the casing from the charging aperture of casing, adjusts two wind-force adjustable plates by screw mandrel, and the pressure differential of controlling casing and net cage changes; When wind-force adjustable plate distance diminishes, casing the first half negative pressure value increases, and when the wind-force value surpassed the gravity of stalk label own, stalk was signed and also is sucked away thereupon; When the wind-force adjustable plate apart from becoming big, the wind-force value is during less than the gravity of pipe tobacco own, pipe tobacco and stalk are signed and are fallen together; Force value when the casing top and the bottom tends to balance, and pipe tobacco upwards is inhaled into air-suction duct and returns and mix, simultaneously stalk sign fall through net cage, air-suction duct sucks the dedusting room down.

The utlity model has following advantage: 1, utilize drainage wind branch principle that broken pipe tobacco and stalk label are separated, heavier stalk is signed to fall and is inhaled into the dedusting room, lighter pipe tobacco is then sucted back to be mixed to pipe tobacco, plays the effect of cost efficiency and assurance production scene neat and tidy; 2, the pressure differential of controlling top and the bottom in the casing by two wind-force adjustable plates by screw mandrel changes, and simple in structure, easy to operate, energy consumption is low, rejects the efficient height, reduces hand labor intensity, improves dry posterior lobe yarn quality, saves the production time;

3, guard one is to realize the inside and outside air exchange, be convenient to regulate, and the 2nd, prevent the production on-site environment pollution.

Description of drawings

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

Among the figure: 1 casing, air-suction duct on 2,3 times air-suction ducts, 4 wind-force adjustable plates, 5 net cages, 6 charging apertures, 7 blanking ports, 8 observation windows.

The specific embodiment

As shown in Figure 1, this air classifier comprises casing 1, last air-suction duct 2, following air-suction duct 3, wind-force adjustable plate 4 and net cage 5, establish charging aperture 6 on the middle and upper part sidewall of casing 1, air-suction duct 2 is installed at the top of casing, two wind-force adjustable plates 4 are installed relatively through screw mandrel in the bottom of casing 1, form blanking port 7 by two wind-force adjustable plates 4, net cage 5 is installed below casing 1, air-suction duct 3 is down installed in the bottom of net cage 5.

Wherein, observation window 8 is installed on a wherein sidewall of casing 1.

During work, the mixture that pipe tobacco and stalk are signed falls in the casing 1 from the charging aperture 6 at casing family, adjusts two wind-force adjustable plates 4 by screw mandrel, and the pressure differential of controlling casing 1 and net cage 5 changes; When wind-force adjustable plate distance diminishes, casing the first half negative pressure value increases, and when the wind-force value surpassed the gravity of stalk label own, stalk was signed and also is sucked away thereupon; When the wind-force adjustable plate apart from becoming big, the wind-force value is during less than the gravity of pipe tobacco own, pipe tobacco and stalk are signed and are fallen together; Force value when the casing top and the bottom tends to balance, and pipe tobacco upwards is inhaled into air-suction duct and mixes for 2 times, and stalk is signed to fall through net cage 5, following aspiration channel 3 roads and sucked the dedusting room simultaneously.

Claims

1. modified VAS air classifier, it is characterized in that: this air classifier comprises casing (1), last air-suction duct (2), following air-suction duct (3), wind-force adjustable plate (4) and net cage (5), establish charging aperture (6) on the middle and upper part sidewall of casing (1), air-suction duct (2) is installed at the top of casing, two wind-force adjustable plates (4) are installed relatively through screw mandrel in the bottom of casing (1), form blanking port (7) by two wind-force adjustable plates (4), net cage (5) is installed in below at casing (1), and air-suction duct (3) is down installed in the bottom of net cage (5).
