Abstract

The utility model discloses a hammer-piece type grinder applied in alcohol industry comprising a machine shell, a rotor, a sieve plate, and an operational gate. The machine shell is composed of a feeding mouth, a discharging mouth, and a wallboard; the rotor is composed of a main shaft, a rotor disk, a hammer piece, and a hammer piece pin; the hammer piece is arranged on the hammer piece pin; a positioning pin is arranged on the rotor disk; a positioning piece and a positioning sleeve are arranged on the positioning pin; the axial displacement restricting of neighbouring hammer piece is done by the positioning piece. The hammer piece of the utility model swings smoothly without deadlocking and can be replaced conveniently.

Description

Beater disintegrating machine

Technical field

The utility model belongs to the raw material pulverizing machine of alcohol industry, also can be used for grain or feedstuff industry.

Background technology

Known alcohol raw material beater disintegrating machine, its structure is that the hammer leaf bearing pin is housed on the rotor disk, hammer leaf and hammer leaf spacer are housed on the hammer leaf bearing pin, and for example Chinese patent CN2060691 discloses a kind of like this structure, in this structure, because hammer leaf comes axial limiting by the hammer leaf spacer, and in hammer leaf when work, require that swing is arranged, so have the gap between hammer leaf and the hammer leaf spacer, and the material powder pierces in this gap and the spacer easily during work, make hammer leaf stuck gradually, influence the crushing effect of hammer leaf; Owing to be drilled with the material powder in the spacer, make spacer and hammer leaf bearing pin stuck simultaneously, be difficult to dismounting, replacing makes troubles to hammer leaf; Because hammer leaf is to arrange according to certain rules on rotor, so require the length of hammer leaf spacer incomplete same, this will learn off the position of hammer leaf spacer when just making the hammer leaf of changing consumable accessory again, and this brings bigger trouble for comparatively frequent replacing hammer leaf work.

Summary of the invention

The purpose of this utility model is to provide a kind of hammer leaf to swing freely and certain axial displacement can be arranged, and changes beater disintegrating machine easily again.

In order to achieve the above object, the utility model is by the following technical solutions: a kind of beater disintegrating machine, comprise casing, rotor, sieve plate and actuating doors, casing has charging aperture, discharging opening and wallboard, rotor has main shaft, rotor disk, hammer leaf and hammer leaf bearing pin, hammer leaf is contained on the hammer leaf bearing pin, and alignment pin also is housed on the rotor disk, and spacer and positioning sleeve are housed on the alignment pin; By spacer adjacent hammer leaf is carried out axial limiting.

After adopting said structure, because alignment pin also is housed on rotor disk, spacer and positioning sleeve are housed on the alignment pin, by spacer adjacent hammer leaf is carried out axial limiting, cancelled the hammer leaf spacer, thereby hammer leaf can swing freely on the hammer leaf bearing pin, can not be stuck, and can on the hammer leaf bearing pin, have certain axial displacement thereby good crushing effect; Again owing to cancelled the incomplete same hammer leaf spacer of length in original technology, thereby do not spend the position of remembeing the hammer leaf spacer when changing hammer leaf as consumable accessory, only need with new hammer leaf be through be placed between the spacer on the hammer leaf bearing pin or spacer and rotor disk between get final product, feasible more change jobs convenient, fast; In addition, because hammer leaf axially can have certain displacement on the hammer leaf bearing pin, thereby during work, the pulverizing of hammer leaf is wider, has improved the ability of sieving, and crushing effect is also better.

Fig. 2 is the structural representation of the utility model rotor.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

As shown in Figure 1, 2, beater disintegrating machine of the present utility model, comprise casing 1, rotor 5, sieve plate 4 and actuating doors 6, casing 1 has charging aperture 2, discharging opening 11 and wallboard 3, rotor 5 has main shaft 12, rotor disk 10, hammer leaf 9 and hammer leaf bearing pin 8, hammer leaf 9 is contained on the hammer leaf bearing pin 8, and alignment pin 14 also is housed on the rotor disk 10, and spacer 7 and positioning sleeve 13 are housed on the alignment pin 14; Carrying out axial limiting by 7 pairs of hammer leaves of spacer 9, also is that hammer leaf 9 is by two adjacent spacer 7 axial limitings, or by adjacent spacer 7 and rotor disk 10 axial limitings.Hammer leaf bearing pin 8 is contained near rotor disk 10 peripheries, and rotor disk 10 is separated by main shaft distance bushing 18 and is fixed on the main shaft 12 with locknut 15.

As shown in Figure 2, for large diameter rotor disk, also can be equipped with on rotor disk 10 and strengthen bearing pin 17, strengthen on the bearing pin 17 spacer 16 being housed, setting up the purpose of strengthening bearing pin 17 is that the rigidity of rotor disk 10 is strengthened; Strengthen bearing pin 17 but also can not adopt.Spacer 7 is a disc, and the center is porose, is sleeved on the alignment pin 14.Spacer 7 also can be a center square structure with holes.Spacer 7 thickness are generally at 2～20mm, and diameter is less than the radius of rotor mill dish.

When the utility model used, as shown in Figure 1, 2, rotor 5 rotated under the drive of motor or other driving mechanism, and hammer leaf 9 keeps consistent with rotor 5 radial directions under centrifugal action, reach overhanging to greatest extent.Adjust the spacing between the spacer 7, can make hammer leaf 9 that certain axial displacement is arranged on hammer leaf bearing pin 8, the ability of sieving is increased, improve crushing effect.When changing the hammer leaf of consumable accessory, need not move spacer 7, only need to extract out hammer leaf bearing pin 8 to change old hammer leaf 9, because spacer 7 positions are to be in to determine state, thereby as long as hammer leaf bearing pin 8 is penetrated hammer leaf 9, the arrangement position of hammer leaf 9 is promptly fixed, changes very for convenient.
