Description

Hammer crusher

The design relates to a kind of sieve set hammer tablet pulverizer that has, usually at feed, and grain, chemical industry, pharmacy is used in the industries such as plastics.

At present, known this class pulverizer kind is a lot, usually by (1) sieve sheet, and (2) hammer leaf, (3) rotor, (4) body, (5) motor waits composition.During work, drive rotor by motor, make epitrochanterian hammer leaf rotation, material is pulverized by hammer leaf, and qualified powder is discharged from sieve aperture.

Home products has SFSP, FSP, and the 9FQ type, patented product: the self-priming husk pulverizer of ZXT-type, the patent No.: ZL9323527.5, etc.The CHAMPION of CPM company is abroad arranged, the DFZC of Switzerland Burl Corp etc. is arranged.

Recently, a kind of sieve set hammer tablet pulverizer appearance that has is arranged, the number of applying for a patent again: 96116579.0, by (1) horizontal wide shape vibratory sieve, (2) hammer leaf, (3) rotor, (4) body, (5) motor, compositions such as (6) vibration source, its technical characterictic is: the horizontal wide shape vibratory sieve and the thin hammer leaf that puts the first edge on a knife or a pair of scissors.Horizontal wide shape is meant on the rotor mill sagittal plane, by sieve sheet, screen frame etc., surrounds the shape of the side of hammer leaf rotational circle, the length of its horizontal direction, be vertical direction length 1.2-4 doubly, like this, laterally hammer sieve gap is big.Vibratory sieve is at sieve nest center of gravity place, and an additional vibration source makes the relative rotor of sieve vibrate in the rotor radial direction, and material not only relies on hammer leaf to hit to stir and passes sieve aperture, but also relies on the vibration of sieve sheet self, makes material pass sieve aperture.

This class pulverizer and pulverizer without sieve, the pressure roller pulverizer, wait other pulverizer to compare, many advantages are arranged, 1, the finished product granularity is guaranteed, no matter the raw material size how, palpus is the sieve aperture by setting all, as is subjected to the raw material diameter after hammer leaf hits not arrive screen size, then continues to pulverize in crushing chamber, up to qualified, just discharge sieve aperture.2, also more convenient to varigrained selection control, as long as change the sieve sheet in different apertures, just can obtain varigrained finished product.

But this class pulverizer also comes with some shortcomings:

1, the sieve sheet often will be changed as consumable accessory.According to " forage standard compilation handbook, publisher: Commercial Information Center of the Ministry of Commerce, feed office of the Ministry of Commerce, the .4. month in 1992, the 444th page, write: " 4.11, when the sieve sheet removed mixed corn in the processing process, should be not less than 120h its service life.”。Be used to process ultra-fine powder, more obvious, sieve aperture is little, the sieve thin thickness, be used for the shrimp feed, aperture Φ 0.5-1.0mm sieves sheet, and thickness has only 0.5-1.0mm, be used for the river eel feed, aperture Φ 0.35mm sieves sheet, and thickness has only 0.3mm, and the life-span is shorter, have only tens hours, have in addition have only tens hours.Often change sieve, processing cost is increased.

2, anti-unexpected hard foreign material damage capability is poor.The preceding working procedure of pulverizer has impurity removing equipment usually, but still has some special hard foreign material, and as steel ball, copper nut etc. enter pulverizer, makes the fragmentation of sieve sheet, and finished product is sneaked into the Lou big grain of sieve, causes product quality accident.

Analyzing its reason, be because this type of pulverizer has only one deck sieve, and its function is two aspects, the one, and sizing screening, the 2nd, wear-resistant anti-broken, by prior art condition and cost situation, obviously can not both take into account.

Aspect wear-resistant anti-breaking,, require the sieve sheet thick because material directly impacts compass screen surface.

See that material centrifugal force formula is as follows: $F=M\×\frac{V^2}{R}$

F material centrifugal force

The V material is subjected to movement velocity after the hammering

The terminal moving radius of R hammer leaf

The M quality of material

By formula as seen, when the pulverizer specification is certain, V then, R are also fixed, and big grain quality of material is big, centrifugal force is big, and is also bigger to the sieve pad wear, the hard foreign material that some are special, and as steel ball, copper nut etc., centrifugal force is bigger, can directly puncture the thick sieve sheet of 3mm, and therefore, sieve sheet thickness is thick more good more.

And the sieve of common usefulness, sieve aperture is little, and the sieve sheet is also thin, (from existing system sieve technology and cost consideration, select commodity to sieve usually, and commodity mesh size and thickness has a ratio restriction.) for example: pig feed requires granularity little, adopts the commodity sieve sheet in Φ 2.5mm hole, and thickness 2.5mm, aquatic feeds require granularity littler, the sieve sheet in commodity sieve Φ 1-0.35mm hole, thickness 1-0.35mm.Therefore, can't resist contingency at all.

Therefore, newly-designed pulverizer, sieve should not be made of one deck, according to function, separates one by one, certain one deck sieve is used for primary election, and have Chinese People's Anti-Japanese Military and Political College's grain wearing and tearing and foreign matter to destroy function, another layer sieve is just specially made the sizing screening function, in this way, go to solve the problem of people for a long time wish to solve always and do not solve all the time " sieve type pulverizer sieve cracky is arranged ".Because the appearance of horizontal wide shape vibratory sieve pulverizer provides a kind of basis, makes this hope become possibility.Horizontal wide shape sieve is hammer sieve relief width laterally, makes possibility that be mounted for of multi-deck screen, and vibratory sieve makes skin sift out material and do not rely on the hammer leaf strike to stir, and finishes and rely on self to vibrate, and becomes possibility.

The design's purpose provides a kind of sieve type pulverizer that has, and under the condition that adopts the general goods sieve, makes its sieve that be arranged long service life, and the ability of the broken sieve of stronger anti-unexpected foreign matter is arranged.

The design's solution is as follows: in sieve set hammer tablet pulverizer is arranged, comprise (1) horizontal wide shape vibratory sieve, and (2) hammer leaf, (3) rotor, (4) body, (5) motor, (6) vibration sources etc. make improvements the wide shape vibratory sieve of horizontal stroke.It is characterized in that: the multi-deck screen of horizontal wide shape vibration.

The multi-deck screen of the wide shape of so-called horizontal stroke vibration is characterized in that: the number of plies of sieve is more than or equal to two-layer, (commonly used two-layer), the inner layer screen of interior one deck (near one deck of hammer leaf), the aperture is bigger, Φ 1-6mm, the sieve sheet is thicker, has 1-7mm thick, outermost one deck sieve, the aperture is less relatively, aperture Φ 0.35-3.5mm, and thickness is less relatively, thickness 0.1-3mm (also available 40-300 order, or thinner screen cloth, clamp with two film perforation Φ 5 or bigger sieve sheet, it can be vibrated).Between the layer and layer of sieve, connect inner layer screen and outer sieve, constitute the sieve interlayer bag, make it can store big grain foreign matter again by the material between two layer screen with inner layer screen material (or sieve aperture is greater than sieve sheet material of inner layer screen).During work, big grain material is at first stopped by inner layer screen, big grain material centrifugal force is big, and is strong to the effect of sieve pad wear, but the inner layer screen abrasion strength is also strong, when running into unexpected foreign matter and entering crushing chamber, inner layer screen is stood in the breach, and stops earlier for a moment, and general inner layer screen is thicker, be not easy fragmentation, just in case wear out inner layer screen, energy also weakens greatly, has been difficult to pass the skin sieve of the second layer again.The foreign matter that passes inner layer screen can enter sieve and the interlayer bag of sieving automatically, is fixed.By the material of inner layer screen, quality is less, and movement velocity weakens, centrifugal force is also less, sieve further sizing screening by skin, greater than the powder of skin sieve sieve aperture, under vibration, can be from the hole of interlayer bag between the two layer screen sheet, return internal layer again, continue to pulverize, less than the powder of skin sieve sieve aperture, under vibration, discharge sieve aperture.With being arranged, sieve type pulverizer adopt one deck sieve to compare, owing to increased large aperture, inner layer screen that thickness is thicker, weakened the abrasive action of material greatly to the skin sieve, and foreign matter is to the direct destruction of skin sieve, tens of times the prolongation in service life of feasible outer sieve, making has the big grain of sieve type pulverizer leakage accident to descend greatly.And inner layer screen broken after, still can continue repeatedly to use because the probability that twice accident squeezed into same broken hole is less, therefore, increase how many costs hardly.
