Description
Technical field
The utility model relates to a kind of pulverizer that has the rotation hammer element, relates in particular to a kind of hammer crusher that is applied to feed processing.
Background technology
The pulverizing of feedstuff is a very important link in the feed processing, through pulverizing the total surface area that can increase the unit mass feed particles, increases the solubility of feed nutrient in animal digestion liquid, improves the digestibility of animal; And the size of pulverizing raw material granularity all has very important influence to complexity and end product quality like subsequent handlings such as granulations; In addition, the size of grinding particle size directly affects production cost, and grinding particle size is more little, helps animal digestion more and absorbs, also help more granulating, but the corresponding increase of power consumption meeting simultaneously, vice versa.How finding optimal balance point between granularity and the power consumption through various technological means, improve the productivity ratio of pulverizer, reduce ton material power consumption, is the direction that the technical staff constantly pursues.
The hammer crusher crushing mechanism: material gets into the pulverizing chamber that is made up of rotor, sieve plate, tooth plate, door and body etc. from the pulverizer charging aperture; Be that hammer leaf end more than the 80m/s contacts with linear velocity immediately; Violent bump after taking place with hammer leaf at a high speed in the material of low speed first; Drawn in accelerating region by hammer leaf, can be enhanced terminal linear velocity in a short period of time, and make circular motion with hammer leaf near hammer leaf at this particle speed.And forming the material circulation layer gradually in the district at full speed, material is also further pulverized simultaneously.After this, because hammer leaf hits material to sieve plate with very high speed, the material that meets granularity requirements is accomplished crushing process through sieve aperture.
It is a very complicated process that material is pulverized, and the factor that influences crushing effect is a lot, and for example, the individual behavior of various particles under high-speed motion state is extremely difficult in the multiphase flow observes or theoretical modeling; A lot of links are also very unclear in the detailed crushing mechanism of the actual generation of material or the crushing process.Shattering more accurate or quantification is also more rare.But generally acknowledge that a key factor that influences beater disintegrating machine energy consumption and efficient is the material circulation layer.After it is generally acknowledged that circulation layer produces, the fine powder part of internal layer is because with changeing phenomenon, no longer receive very strong hammer force, and mainly born task that friction pulverize by sieve aperture this moment.But because the resultant radial force that receives of material in the circulation layer makes a concerted effort much smaller than its tangential, radial velocity is also much smaller than tangential velocity, thereby when making material particles tangentially direction being streaked sieve aperture, because its radial velocity is not enough, can't pass through sieve aperture.Circulation layer has caused less than the material that minces of sieve aperture and can not in time discharge, and causes separative efficiency to reduce, material is excessively pulverized, ineffective power consumption increases, pulverizer production efficiency reduces and temperature of charge raises.The too high heat-sensitive ingredients that can destroy in the material of temperature of charge when temperature is too high even cause incidents of spontaneous combustion, is added the complexity that heat sink has further increased pulverizer for this reason specially, has improved cost.In order to destroy circulation layer, people have used negative pressure air intake device, non-circular sieve plate, have changed ways such as crushing chamber shape, rotor center biasing.Though pulverizer production efficiency is increased, does not fundamentally solve the material screening problem yet.
On the other hand, along with hammer crusher to large scale development, the pulverizing chamber volume is increasing, the parcel pulverizing chamber sieve plate also increasing.The sieve plate of hammer crusher is processed by sheet metal or iron sheet punching usually, and the hole diameter of sieve (perforated) plate that is used to produce the fishes and shrimps aquatic feeds is usually less than 1mm, and its thickness is usually also below 1mm.This type of rigidity of material is lower, when being configured as the bigger shape of radius of curvature, and can be because the not enough depression that produces of material tension rigidity.Sieve plate depression position very easily with the hammer leaf collision of high speed rotating, make sieve plate wearing and tearing occur or punctured by foreign matter.If the sieve plate impaired area is little, the method reparation of available riveting benefit or soldering; If large tracts of land is damaged, then need more renew sieve plate.Not only improve maintenance cost, shortened the mean time between failures, and wasted a large amount of materials.
