Description

The helical incision type pulverizer

Technical field

The utility model relates to a kind of pulverizer that rotates cutting plate that has.

Background technology

At present, in the production process that material is pulverized,, as pulverize, often must make material have the granularity requirements of certain limit, so that carry out the processing again of next procedure to raw material or finished product.Its grinding mode is generally distinguished by the effect of practical operation, mainly is divided into following four class modes: one, squash type is pulverized, and for example, formula pulverizer etc. is pricked in dental lamina jaw crusher, two rolling; Two, impacting type pulverizer, for example, beater grinder etc.; Three, abrading type is pulverized, for example, and ball mill etc.; Four, splitting formula is pulverized, and for example arranges tooth twin-roll pulverizer or the like.The method of above-mentioned several basic pulverizing, except that abrading type is pulverized, other several grinding modes, be no restriction material is pushed or splitting is ground into different shape and the same material.In the crushing operation process, often in order to guarantee the requirement of raw meal particle size after coarse crushing, need the coarse crushing material is sieved, and then thick material turned back in the Roughpulverizer pulverize once more, just can reach the desired raw meal particle size of technology.Therefore, the pulverizer of above-mentioned several forms energy consumption in operating process is big, powder is many, noise is big.Especially need satisfy the big sheet material of crushing quantity under vacuum condition, and raw meal particle size is required evenly, and the technological requirement that can carry out next procedure rapidly, the operation easier of its technology is very obvious.Several pulverizers that provide in the market are generally two rolling cut axles, or more, use stent support respectively, each rolling cut axle is respectively by separately driven by motor, or by a high-power driven by motor, this cutting type pulverizer is big with energy consumption, installs complicated; Also having a kind of is exactly to have only a rolling cut axle, and the stationary knife blade is housed on its two side, has filled blade on this rolling cut axle, and the benefit of this cutting mill is that single pulverizing speed is fast.But rolling cut axle construction complexity, noise is big, and power consumption is big, granularity inequality, and bad continuous material feeding.

Summary of the invention

For overcoming the shortcoming of above-mentioned pulverizer, it is a kind of low in energy consumption that the utility model provides, epigranular, and helical incision type pulverizer that can continuous feeding.

To achieve the above object of the invention, the utility model is achieved in that a kind of helical incision type pulverizer, by feed well, about two frames, two decide cutting plate, the rolling cut axle, motor and discharge port constitute, described two decide cutting plate be separately fixed at about on two frames, two frames top about described feed well places, described discharge port places two frame lower, described motor is fixed in an end of frame, and motor shaft links to each other with the rolling cut axle, it is characterized in that: described rolling cut axle is positioned at two to be decided in the middle of the cutting plate, describedly decides to be fixed with on the cutting plate YIPAISHU dentation stationary knife blade, and spacing is 19mm～21mm between each stationary knife blade; Spirality is provided with the moving knife blade on the described rolling cut axle, and spacing is 19mm～21mm between the moving knife blade, is 7 degree～8 degree angles between described each moving knife blade and distributes, and described moving knife blade intersects mutually with the stationary knife blade.

Above-mentionedly describedly decide on the cutting plate that spacing is 20mm between each stationary knife blade; On the described rolling cut axle between the moving knife blade spacing be 20mm; Being 7.5 degree angles between the described moving knife blade distributes.

Above-mentionedly describedly decide cutting plate and be fixed on the frame by wide " C " shape plate supporting frame of 40mm.

Above-mentioned described stationary knife blade and moving knife blade are the stainless steel blade of 120 * 40 * 10mm.

Above-mentioned described motor is a variable-frequency motor.

Above-mentioned described about the outer surface of two frames be with heating jacket.

Invention effect of the present invention is: utilizing technique scheme, is single because the rolling cut axle adopts, can impetus be arranged to the material thing during moving knife blade charging of helical pattern, thereby reduce the work energy consumption of motor; On the other hand, because stationary knife blade and moving knife blade be evenly distributed, and the relative angle unanimity of moving knife blade, therefore the raw meal particle size of generation is even when cutting; Because of machine exterior is with heating jacket, therefore avoid material to make moist.Make processing technology perfect more.

Fig. 1 is a rolling cut axle schematic diagram of the present utility model;

Fig. 2 for rolling cut axle of the present utility model with decide the schematic diagram that cutting plate matches;

Fig. 3 is a side view of the present utility model.

Specific embodiment

Below in conjunction with accompanying drawing, the utility model will be further described.

Referring to Fig. 3, the utility model feed well 1, about two frames 2, decide cutting plate 3, rolling cut axle 4, axle sleeve 5, moving knife blade 6, motor 7 and discharge port 8 constitutes, described frame 2 is divided into left frame 21 and right frame 22, and casing 23; Describedly decide cutting plate 3 and be divided into again that cutting plate 31 decide on a left side and cutting plate 32 is decided on the right side; A described left side is decided the holder of wide " C " shape of cutting plate 31 usefulness 40mm and is pulled on the left inwall that frame is fixed on casing 23, the described right side is decided cutting plate 32 and is fixed on the right inwall of casing 23 with wide " C " shape plate supporting frame of 40mm equally, deciding to be fixed with respectively on the cutting plate YIPAISHU dentation stationary knife blade space about described is 20mm, the described every corrosion resistant plate that the stationary knife blade is 120 * 40 * 10mm; Described feed well 1 places two frames top, and described discharge port 8 places the below of two frames, and described motor 7 is fixed in an end of frame 2, and motor 7 can connect reductor, and the arbor of its motor shaft or deceleration and rolling cut axle 4 join;

Described rolling cut axle 4 is fixed in two by support decides cutting plate 3 centres, on the described rolling cut axle 4 axle sleeve 5 is housed, and spirality is provided with moving knife blade 6 on axle sleeve, and spacing is 20mm between the moving knife blade 6; Described each moving knife blade 6 order are 7.5 degree angle spirality and are welded on the axle sleeve 5, and above-mentioned described every moving knife blade 6 is the corrosion resistant plate of 120 * 40 * 10mm; Described moving knife blade 6 cooperatively interacts with the stationary knife blade and intersects.

For processing materials is not made moist, keep dry, therefore in such scheme, can on the surface of outer frame, put heating jacket 9, make entire machine maintain the temperature at 15 ℃, avoid producing dew point from face.

Open motor, in material enters into feed well, driven by motor rolling cut axle rotates, because the moving knife blades aligned on the rolling cut axle sleeve is shape in the shape of a spiral, therefore, when the first rotates the moving knife blade and the stationary knife blade intersects, when cutting off material, moving knife blade thereafter promotes its material when rotating forward and advances, when second moving knife blade and two stationary knife blades intersect, other moving knife blade does not contact with the stationary knife blade, just play the effect that promotes material, so rotation is worked continuously thereby formed, owing to have only a moving knife blade and two stationary knife blades to intersect, at every turn so its noise is little, powder is few, the kinetic energy that consumes is little.
