Abstract
The utility model relates to a high-speed crusher, which applies to fine chemical industry, in particular to crushing amino moulding plastics. By means of the technological transformation of a traditional hammer crusher, a traditional hammer is changed to a current hammer and the differences between the traditional hammer and the current hammer are that two ends of the traditional hammer are provided with four operating angles and single end of a current hammer is provided with two operational angles, and double shaft holes of the traditional hammer are changed to a single shaft hole. Simultaneously, one end of the hammer without the operating angles is made to an arc shape so as to avoid adhesion of particles of materials. In addition, by varying the installation method of the hammers, the hammers are installed on sleeves so that the problems that the materials fall to the middle of the sleeves and a hammer pin, and black pots appear on the amino moulding plastic particles after being smeary in the process of crushing are avoided. The non-defective rate of the particles of the amino moulding plastics is effectively increased by adopting the technology comprehensively.
Description
Technical field
The utility model relates to a kind of disintegrating machine that has the rotation hammer element, relates in particular to a kind of high speed disintegrator that is applied to the amino film plastics industry.
Background technology
In the amino film plastics industry, the pulverizing of plastics is very important links in the processing.The size of pulverizing raw material granularity all has very important influence to complexity and end product quality as subsequent handlings such as granulations; In addition, the size of grinding particle size directly affects production cost, and grinding particle size is more little, 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 by various technological means, improve the productivity ratio of pulverizer, is the direction that the technical staff constantly pursues.
The beater grinder crushing mechanism: material enters the pulverizing chamber that is made 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 at this particle speed, and make circular motion with hammer leaf near hammer leaf.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 to sieve plate with very high speed with material, the material that meets granularity requirements is finished crushing process by 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 be subjected to very strong hammer force, and mainly born task that friction pulverize by sieve aperture this moment.But because the resultant radial force that is subjected to of material in the circulation layer tangentially makes a concerted effort much smaller than it, 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.
In the amino film plastics preparation process, material itself is relatively more responsive to temperature, and temperature of charge thickener occurs after raising easily, stain occurs, causes the product quality deterioration.Material also can be attached on the structural members such as sieve plate, hammer frame plate, axle sleeve, hammer leaf, hammer bearing pin, rotor, stops up disintegrating machine.If this adds heat sink specially, then further increased the complexity of pulverizer, raise the cost.
In the prior art, be the arrangement of " axle sleeve-hammer leaf-axle sleeve-hammer leaf " on the hammer bearing pin.In the amino film plastics shattering process, hammer leaf serves as that axle rotates with the hammer bearing pin also when carrying out circular motion around rotor.This rotation meeting mixes the lubricating oil that the amino film plastics fine particle is involved in axle sleeve and the axle sleeve, drops behind the formation dirt, causes flaws such as stain in the amino film plastics finished product, has a strong impact on product quality.
The tradition hammer crusher, respectively there are two operating angles at each hammer leaf two ends, and two axis holes are arranged on each hammer leaf.During hammer crusher work, hammer leaf is installed on the hammer bearing pin by the axis hole away from the working end.After the hammer leaf wearing and tearing at one end, the hammer leaf of turning round uses the work of the hammer leaf other end.That is, when traditional hammer crusher was worked, two operating angles that hammer leaf does not participate in pulverizing were in idle state.Because amino film plastics can raise to feel like jelly and become sticky with temperature, and temperature of charge can raise inevitably in the crushing process, and is more obvious under summer high temperature environment.When the hammer leaf operating angle is shown in Figure 4 when having sawtooth, the amino film plastics particulate will be attached on and form little agglomerate on two operating angles that do not participate in pulverizing.This little agglomerate drops to sieve and sneaks in the amino film plastics particle, will form fault in the amino film plastics finished product.
