CN2418948Y - Labyrinth style special material pulverizer - Google Patents

Abstract

The utility model relates to a labyrinth style special material pulverizer, which is used for pulverizing special materials, such as barks, bamboo scraps, fibers, dried vegetables, etc. The utility model is characterized in that a material feeding end in a machine casing is provided with double fixed rings, a rotating disk is provided with double movable rings, and a labyrinth style passage is formed between the double fixed rings and the double movable rings; the surfaces of inner and outer rings of the double fixed rings and the double movable rings are provided with diamond-shaped cone teeth. The pulverizer effectively solves the problem that the rate of cutting up long fibers us low.

Description

Labyrinth type characteristic materials crusher

The utility model relates to a kind of special material grinding machines such as bark, wood chip, bamboo bits, fiber, dry vegetalbe, rubber, plastics, feather that are used to pulverize.

Along with science and technology development, need the material crushed kind also more and more, existing similar pulverizer has toothed disc type, prism and gear type, their common weak points are that material enters that pulverizing path behind the pulverizer is short, the fibre cutting rate is low, thereby do not satisfy the granularity requirements of new industry to powder.

The purpose of this utility model is a kind of labyrinth type characteristic materials crusher that designs at the deficiency of above equipment existence, it can make fibre material or flexible material repeatedly be cut upset repeatedly by mill through the zigzag path in labyrinth, thereby effectively raise the cut-out rate of fiber, improved fineness.

The utility model is achieved in that labyrinth type characteristic materials crusher is included in bearing block 2 and casing 8 is housed on the support 1, two ends, the left and right sides and interior circle at casing 8 have charging aperture 3, discharging opening 11 and lining ring 7 respectively, rotating disk 6, internal classification wheel 9 and wind wheel 10 are housed successively at the middle part of rotating shaft 12, wherein, left end in the casing 8 is equipped with double fixed ring 4, and double movable ring 5 is housed on rotating disk 6.

The utility model can also be achieved in that the surfaces externally and internally at double fixed ring 4 and double movable ring 5 has the rhombus cone tooth.

Good effect of the present utility model is:

1, because the utility model adopts double fixed ring and double movable ring to form labyrinth channel, so material can be overturn during through labyrinth channel repeatedly, effectively avoided being difficult for cut phenomenon along the long fibre of rotor motion direction arrangement.

2, because the utility model has the rhombus cone tooth at the surfaces externally and internally of double fixed ring and double movable ring, the angle of its longitudinal edge and the direction of motion is less than 45 °, the effect that its longitudinal edge has dragsaw to cut to material, so it can pulverize flexibility or fiberous material more tiny.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the profile according to the labyrinth type characteristic materials crusher that the utility model proposes.

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

As shown in Figure 1.Bearing block 2 and casing 8 are housed on support 1 of the present utility model, at the two ends, the left and right sides of casing 8 charging aperture 3 and discharging opening 11 are arranged respectively, left end in casing 8 and interior circle are equipped with double fixed ring 4 and lining ring 7 respectively.Its right-hand member is equipped with the interior round heart of the rotating shaft 12 of belt pulley 13 through casing 8, and rotating disk 6, internal classification wheel 9 and wind wheel 10 are housed successively at the middle part of rotating shaft 12, and the double movable ring 5 that is contained on the rotating disk 6 forms labyrinth channel with double fixed ring 4.

As shown in Figure 1.The course of work of the present utility model is: motor drives rotating shaft 12 rotations by belt pulley 13, be installed in the rotating disk 6 in the rotating shaft 12, internal classification wheel 9 and wind wheel 10 be rotation thereupon also, the material that needs to pulverize enters in the casing 8 from charging aperture 3, under the attraction of negative-pressure air-flow, cut repeatedly through double fixed ring 4 and the labyrinth channel that double movable ring 5 forms, rub with the hands and grind and pulverize, powder concentrator is sent into from discharging opening 11 in the back of roughly selecting through internal classification wheel 9, after the powder concentrator sorting, fine powder enters powder collector and is collected the back pack, and meal then returns charging aperture 3 and repeats above-mentioned circulation.

Claims (2)

1, a kind of labyrinth type characteristic materials crusher, it comprises: bearing block (2) and casing (8) are housed on support (1), two ends, the left and right sides and interior circle at casing (8) have charging aperture (3), discharging opening (11) and lining ring (7) respectively, at the middle part of rotating shaft (12) rotating disk (6) is housed successively, internal classification wheel (9) and wind wheel (10), it is characterized in that: the left end in casing (8) is equipped with double fixed ring (4), double movable ring (5) is housed on rotating disk (6).

2, labyrinth type characteristic materials crusher according to claim 1 is characterized in that: there is the rhombus cone tooth on the inner and outer ring surface at double fixed ring (4) and double movable ring (5).
