Abstract
The invention relates to a grinder, in particular to a hammer slice for a hammer slice type grinder. The hammer slice comprises a hammer slice body (1), wherein, a hammer slice mounting hole (1-1) is formed on the hammer slice body (1); the hammer slice body (1) comprises a left side surface (1-2), a right side surface (1-3) and a bottom end surface (1-4); a wear-resistant layer (2) which comprises side surface wear-resistant layers (2-1) and a bottom end wear-resistant layer (2-2) is arranged on the hammer slice body (1); the side surface wear-resistant layers (2-1) are arranged at the lower part of the left side surface (1-2) and the lower part of the right side surface (1-3); the bottom end wear-resistant layer (2-2) is arranged on the bottom end surface (1-4); the cross section of each side surface wear-resistant layer (2-1) is triangle-shaped; and the cross section of the bottom end wear-resistant layer (2-2) is rectangle-shaped. The hammer slice has the advantages of simple structure, high wear resistance, long service life, low use cost and steady product quality, and is convenient and easy to manufacture.
Description
Technical field
The present invention relates to a kind of pulverizer, particularly a kind of hammer slice for hammer slice type grinder.The invention belongs to plant equipment manufacturing technology field.
Background technology
At present, beater disintegrating machine is widely used in the industries such as feed, grain, food, medicine, chemical industry.Beater disintegrating machine is a kind of common plant equipment that material is pulverized.Beater disintegrating machine is comprised of pulverizing chamber, conveying device etc., during work, processed material enters in the pulverizing chamber, is subject to repeated stock, friction and the collision on tooth plate of the hammer leaf of High Rotation Speed, is leaked down by sieve aperture thereby progressively be crushed to the granularity that needs again.Hammer leaf is the main working parts of beater disintegrating machine, and hammer leaf very easily weares and teares, so hammer leaf is the quality that consumable accessory needs often to change the guarantee hammer leaf, to guarantee the splendid crushing effect of material.The defective that existing hammer slice for hammer slice type grinder exists is: (1) hammer leaf wears no resistance, and needs often to change hammer leaf, this so that use cost greatly increase; Need to shut down when (2) changing hammer leaf and carry out, affect on the one hand production efficiency, production efficiency descends; Often change on the other hand that hammer leaf also makes troubles to the user and inconvenience, do not affect the crushing material quality but do not change, affect the stability of product quality, can cause the generation of substandard product.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, provide a kind of simple in structure, easy to make, wearability is good, long service life, hammer slice for hammer slice type grinder that use cost is low.
The technical scheme that realizes above-mentioned purpose is: a kind of hammer slice for hammer slice type grinder, comprise the hammer leaf body, have the hammer leaf installing hole on the hammer leaf body, the hammer leaf body includes left surface, right flank and bottom face, be provided with wearing layer on the described hammer leaf body, wearing layer is comprised of side wearing layer and bottom wearing layer, the side wearing layer is arranged on the bottom of left surface and the bottom of right flank, the bottom wearing layer is arranged on the bottom face, the shape of cross section of side wearing layer is triangle, and bottom wearing layer shape of cross section is rectangle.
Further, the hardness of described wearing layer is HRC70.
Further, the making material of described wearing layer is carbide alloy.
After adopting technique scheme, have a lot of benefits: (1) the present invention is provided with wearing layer at the hammer leaf body, and wearing layer is arranged on the bottom and bottom face of bottom, right flank of left surface.This structure of the present invention is very simple, and is easy to make easy; And because wearing layer is arranged on the bottom and bottom face of bottom, right flank of hammer leaf when work left surface easy to wear, this is so that the present invention is in the hammer leaf position the most easy to wear of workspace is wrapped up by wearing layer, therefore wearability of the present invention increases greatly, wearability is good, long service life, use cost is low, and the replacement cycle is long, production efficiency is high, brings convenience to the user; The shape of cross section of side of the present invention wearing layer is triangle in addition, and bottom wearing layer shape of cross section is rectangle, makes position the most easy to wear thicker, and this is also so that wearability of the present invention is good, long service life.(2) but because the hammer leaf long period of the present invention maintains good duty, so crushing material is effective, constant product quality, product percent of pass is high.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1, hammer leaf body, 1-1 hammer leaf installing hole, 1-2, left surface, 1-3 right flank, 1-4 bottom face, 2 wearing layers, 2-1 side wearing layer, 2-2 bottom wearing layer.
The specific embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples.
Embodiment
As depicted in figs. 1 and 2, a kind of hammer slice for hammer slice type grinder comprises hammer leaf body 1, has hammer leaf installing hole 1-1 on the hammer leaf body 1, and hammer leaf body 1 includes left surface 1-2, right flank 1-3 and bottom face 1-4.Be provided with wearing layer 2 on the described hammer leaf body 1, wearing layer 2 is comprised of side wearing layer 2-1 and bottom wearing layer 2-2.Side wearing layer 2-1 is arranged on the bottom of left surface 1-2 and the bottom of right flank 1-3, and bottom wearing layer 2-2 is arranged on the bottom face 1-4.The shape of cross section of side wearing layer 2-1 is top little following large triangle, and namely the upper part of side wearing layer 2-1 is thin, lower part is thick, and wearing layer 2-1 thickeies gradually from top to bottom.Bottom wearing layer 2-2 shape of cross section is rectangle.The hardness of described wearing layer 2 is HRC70, and the making material of wearing layer 2 is carbide alloy.
The making material carbide alloy of wearing layer 2 of the present invention has a series of premium properties such as hardness height, wear-resisting, intensity and toughness is better, heat-resisting, corrosion-resistant, particularly its high rigidity and wearability are very outstanding, even under 500 ℃ temperature, also substantially remain unchanged, in the time of 1000 ℃, still have very high hardness, carbide alloy is widely used as cutter material, such as lathe tool, milling cutter, planing tool, drill bit, boring cutter etc.The sclerosis of the making material carbide alloy of wearing layer 2 of the present invention is tungsten carbide, titanium carbide or ramet etc. mutually, and the Binder Phase of the making material carbide alloy of wearing layer 2 is the iron group metals such as cobalt or nickel.
The thickness of side wearing layer 2-1 of the present invention is advisable with 2～5mm, and the base thickness of bottom wearing layer 2-2 is advisable with 5～10 mm, is advisable with 50～70 ° in the inclination angle of bottom wearing layer 2-2.The hardness of carbide alloy is that HRC70 is advisable, and can reach instructions for use of the present invention, and cost performance is high again.Certainly carbide alloy also can adopt higher hardness, but cost can be relatively high.
Embodiments of the invention also have a lot, can't be exhaustive, all employings and the present invention be equal to or equivalent technical scheme all within the scope of protection of the invention.
