Abstract

The utility model discloses a short-fiber smasher, which comprises a base and a main motor, wherein the main motor is fixed on the base; a host machine is arranged on the base, and comprises a main shaft, a rotor piece and a tooth-shaped lining plate; the rotor piece consists of a grading disk and at least two layers of smashing cutter heads; the rotor piece is fixed on the main shaft through a flat key and a bolt; the rotor piece is vertically placed; an upper bearing matched with the upper part of the rotor piece is fixed an upper bearing base; a lower bearing matched with the lower part of the rotor piece is fixed on a lower bearing base; the upper bearing base and the lower bearing base are connected with a shell through bolts; the tooth-shaped lining plate is fixed inside the shell by using a bolt, and small gaps are formed between the tooth-shaped lining plate and the smashing cutter heads; smashing blades are fixed on the smashing cutter heads through bolts; and at least twelve smashing blades are uniformly arranged on a single layer of smashing cutter head. The short-fiber smasher has high shearing efficiency specific to short fiber material smashing, low unit energy consumption and superior energy-saving and emission-reducing effects; and meanwhile, a certain drying effect is achieved by scattering a material through high-frequency vibration of air current, so that the water content of the material can be effectively lowered, and humidity is lowered.

Description

A kind of short fiber pulverizer

Technical field

The utility model relates to a kind of pulverizing machine, especially a kind of short fiber pulverizer.

Background technology

At present domestic disintegrating apparatus for pulverizing the short fiber material is take air-flow vortex micropowder grinding ACM-60 type as main, this type is installed on the abrading block on the rotating disk and reaches the purpose of pulverized fiber with the airflow collision between the tooth stator by High Rotation Speed, and is not strong for the specific aim of short fiber.Their characteristics are only to rely on to impact rubbing and grinding and material is pulverized gradually, temperature rise is higher in the production process, energy consumption is large, noise is large, granularity behind the crushing material generally is no more than 80 orders, yield poorly, can not adapt to the at present requirement to cellulose granularity and output in fields such as new material, chemical industry, medicine, food.It is also relatively backward that at present domestic existing cellulose is pulverized equipment type principle, and productivity ratio is not high.

The utility model content

The utility model is pulverized the problems such as equipment yield is low, product granularity is not up to standard, size distribution is uneven, structural principle is backward for present cellulose, purpose is to provide a kind of special design for short fiber class crushing material, not only significantly improve output, reduce energy consumption, improving product fineness, and have the function of desiccant dehumidification.

For achieving the above object, the technical solution of the utility model is: a kind of short fiber pulverizer of the utility model, comprise support, be fixed on the main motor on the support, be provided with main frame on the support, main frame comprises main shaft, rotor element and profile of tooth liner plate, rotor element is by 1 singulizing disc, pulverizing cutterhead at least 2 layers forms, the rotor element flat key, be bolted on the main shaft, rotor element is vertically placed top and is mixed bearing and be fixed on the top chock, the bottom is joined lower bearing and is fixed on the step, top chock is connected bolt to be connected with casing with step, the profile of tooth liner plate is fixed in casing inside and the gap less with the maintenance of pulverizing cutterhead with bolt, and Disintegrating knife is bolted on to be pulverized on the cutterhead, and individual layer is pulverized at least 12 Disintegrating knifes of even installation on the cutterhead.

As further setting: the quantity that forms the pulverizing cutterhead of rotor element is 3～8 layers.

As further setting: the diameter of rotor element is 400～2000mm.

As further setting: individual layer is pulverized 12～80 Disintegrating knifes evenly is installed on the cutterhead.

The beneficial effects of the utility model are: the utility model can be by regulating the blade and the fineness of the gap adjustment product between the profile of tooth interior lining panel on the cutterhead, and the quantity of classification rod controls product fineness and output on rotating speed that also can be by the adjusting rotor, the singulizing disc; It is high that the utility model has shear action efficient for the short fiber crushing material, and specific energy consumption is little, has excellent effects of energy saving and emission reduction; Possess certain drying effect because the dither of air-flow is broken up material simultaneously, can effectively reduce material moisture, reduce humidity.

Description of drawings

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

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

Among the figure: top chock 1, main shaft 2, upper bearing (metal) 3, singulizing disc 4, pulverizing cutterhead 5, profile of tooth liner plate 6, Disintegrating knife 7, main motor 8, feed space 9, lower bearing 10, step 11, support 12, rotor element 13.

The specific embodiment

Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.

As shown in the figure, a kind of short fiber pulverizer of the utility model, comprise support 12, be fixed on the main motor 8 on the support 12, be provided with main frame on the support 12, main frame comprises main shaft 2, rotor element 13 and profile of tooth liner plate 6, rotor element 13 is by 1 singulizing disc 4, pulverizing cutterhead 5 at least 2 layers forms, rotor element 13 is used flat key, be bolted on the main shaft 2, rotor element 13 vertical placement tops are mixed bearing 3 and are fixed on the top chock 1, the bottom is joined lower bearing 10 and is fixed on the step 11, top chock 1 is connected with step and is connected with casing with bolt, profile of tooth liner plate 6 usefulness bolts are fixed in casing inside and the gap less with 5 maintenances of pulverizing cutterhead, and Disintegrating knife 7 is bolted on to be pulverized on the cutterhead 5, and individual layer is pulverized at least 12 Disintegrating knifes 7 of even installation on the cutterhead 5.

As further setting: the quantity that forms the pulverizing cutterhead 5 of rotor element 13 is 3～8 layers.

As further setting: the diameter of rotor element 13 is 400～2000mm.

As further setting: individual layer is pulverized 12～80 Disintegrating knifes 7 evenly is installed on the cutterhead 5.

Operation principle of the present utility model is: after moist short fiber material is evenly sent into feed space 9 by feeder, in swirling eddy accelerates to enter the crushing chamber of profile of tooth liner plate 6 and 5 of multilayer pulverizing cutterheads, rotor high-speed rotates and forms disorderly turbulent flow, and constantly sheared by Disintegrating knife 7 and profile of tooth liner plate 6, the ultrasonic wave that forms simultaneously makes the air-flow dither, and material mutually impacts and be dry.Singulizing disc 4 screenings that crushing rear material is comprised of the classification rod, qualified fines is discharged from the main frame discharging opening, and defective coarse fodder is back to the main frame lower end, again pulverizes, until qualified.
