  木屑颗粒机为什么要控制电流?我们都知道我们需要控制木屑颗粒机的电流,那么为什么我们需要控制电流呢?相信大家可能不全明白,今天由木屑颗粒机批发厂家帮大家解释一下原因。
  Why do we need to control the current of the chip granulator? We all know that we need to control the current of the chip granulator, so why do we need to control the current? I believe you may not fully understand. Today, the wholesale manufacturer of the chip granulator will help you explain the reason.
  木屑颗粒机在生产过程中,通常将分布在压榨间的粉层分为三个不同的区域:供料区、压紧压和挤压区。
  In the production process of wood chip granulator, the powder layer distributed in the pressing room is usually divided into three different areas: feeding area, pressing area and pressing area.
  在挤压区,随着压力的增加,材料的挤出压力层超过模孔的摩擦阻力,和粒子逐渐挤进模孔形成理想的生物质颗粒燃料,然后切成所需长度的粒子刀。压缩区,形成的环模辊工作楔角小于临界角的摩擦材料层,材料层与滚筒的旋转驱动和同步运动,挤压区域,随着压缩区任意横截面面积和减少运动,材料层逐渐压力,密度增加,但其内部压力每一点并不足以克服模孔的摩擦阻力,所以床是不断被压缩的,但不会死。
  In the extrusion zone, with the increase of the pressure, the extrusion pressure layer of the material exceeds the friction resistance of the die hole, and the particles gradually squeeze into the die hole to form an ideal biomass particle fuel, and then cut into the particle knife of the required length. In the compression area, the friction material layer formed with the working wedge angle of the ring die roller less than the critical angle is driven by the rotation and synchronous movement of the material layer and the roller. In the extrusion area, with the reduction of any cross-sectional area of the compression area and the movement of the material layer, the pressure and density of the material layer gradually increase, but each point of the internal pressure is not enough to overcome the friction resistance of the die hole, so the bed is continuously compressed, but will not die.
  2. 此外,在补给区,因为形成的楔角环模和压辊大于材料的临界摩擦角层,材料层不是捕获并向前发展,但堆积在环模和压辊之间。随着前压区材料层的向前运动,逐渐填满了环模和压辊旋转时不断形成的新压区空间。
  2. In addition, in the replenishment area, because the wedge angle ring die and pressing roll formed are larger than the critical friction angle layer of the material, the material layer does not catch and develop forward, but piles up between the ring die and pressing roll. With the forward movement of the material layer in the front pressing zone, the new pressing zone space formed continuously during the rotation of the ring die and the pressing roller is gradually filled.
  除非木屑颗粒机处于空转状态,只要有一定量的物料进料,这三个区域将同时存在,但前提是任何特定的可变因素暂时假定不变,对于每个特定的工况。理论上,挤压区和压缩区都有一个特定的值。当饲料的能力很小,投喂区材料层厚度小于理论压实面积的起点,挤压区域,压实区域是一个变量,间隔长度的变化将改变进给速率的大小的变化,如果饲料能力小于允许的,在这一点上,压缩压缩终点起点。

  Unless the chip granulator is idling, as long as there is a certain amount of material feeding, these three areas will exist at the same time, provided that any specific variable factors are temporarily assumed to be unchanged for each specific working condition. Theoretically, there is a specific maximum value in both the compression region and the compression region. When the feed capacity is very small, the thickness of the material layer in the feeding area is less than the starting point of the theoretical maximum compaction area. The extrusion area and the compaction area are variables. The change of the interval length will change the change of the feed rate. If the feed capacity is less than the maximum allowable, at this point, the starting point of the compression end point.
  挤压区域的端点是恒定的,即环模轴与压辊轴之间的连接延伸至压辊外圆处。作为起点挤压压力区,材料原始压力(因为循环死设置参数都是一样的),理论不会缩短压缩带的长度,相反会延长(移动,压缩区年底到挤压区域在同一个区间长度,狭小的空间)的数量的减少,因此更终的结果是挤压的间隔长度减少,从而导致挤出量的减少。
  The end point of the extrusion area is constant, that is, the connection between the ring die shaft and the roller shaft extends to the outer circle of the roller. As the starting point of the extrusion pressure zone, the original pressure of the material (because the cyclic dead set parameters are the same), the theory will not shorten the length of the compression band, on the contrary, it will lengthen the number of (moving, the length from the end of the compression zone to the extrusion zone in the same interval, narrow space) reduction, so the final result is the reduction of the extrusion interval length, resulting in the reduction of the extrusion amount.
  无论材料的厚度或厚度层补给区,它不能被压缩,也就是说,它的存在并不消耗的能量制粒机(之间的相对滑动摩擦能量消耗粉和环模和压辊被忽略);
  No matter the thickness of the material or the thickness layer supply area, it can not be compressed, that is to say, its existence does not consume the energy of the granulator (the relative sliding friction energy consumption between the powder and the ring mold and the pressing roller are ignored);
  当温度、湿度、压比等诸多相关因素不变时,对于每个特定的球团环境,根据这三个区域,一旦确定压缩区和挤压区理论上有效的工作范围就不会改变。事实上,随着材料层厚度在个区域(进料区域)的调整,只要不超过压缩区域的起始点,前两个区域就会随着材料量的变化而在零点和值区间内变化;
  When the temperature, humidity, pressure ratio and other related factors remain unchanged, for each specific pellet environment, according to these three areas, once the theoretical effective maximum working range of compression area and extrusion area is determined, it will not change. In fact, with the adjustment of the thickness of the material layer in the first region (feeding region), as long as the maximum starting point of the compression region is not exceeded, the first two regions will change in the zero and maximum range with the change of the material quantity;
  在木屑颗粒机的工作中,环模和压辊以匀速旋转,各瞬间的工作状态基本相同。在不改变进给量的情况下,能量消耗应该相对稳定,电流反映在电机上时相对稳定。
  In the operation of the chip granulator, the ring die and the pressing roller rotate at a uniform speed, and the working state of each instant is basically the same. Without changing the feed rate, the energy consumption should be relatively stable, and the current reflected on the motor should be relatively stable.
  木屑颗粒机制粮食,我们调整饲料的材料面积的大小,只要是厚度小于压力区起点,将直接影响压实区,挤压区域的有效工作长度,并导致电流的变化波动和输出,和饲养区如果材料厚度大于压力区的起点,除增加料带厚度外,在单位时间内对成品率和能耗没有任何影响,也不会引起电流和产量的变化。由于进料区厚度超过了压缩区的起始点,压缩区与挤压区之间的间隔是恒定的,没有任何变化。这样,随着进料量的增加,进料口和出料口的平衡被打破,进料口大于出料口。进料区域的材料层会越积越厚,直到填满所有的缝隙和块到进料口,使得木屑颗粒机无法正常工作。这就会引起焖烧现象。
  For the grain made of sawdust particles, we adjust the material area of feed. As long as the thickness is less than the starting point of the maximum pressure area, it will directly affect the compaction area, the effective working length of the extrusion area, and lead to the fluctuation and output of the current. And if the material thickness in the feeding area is greater than the starting point of the maximum pressure area, In addition to increasing the thickness of the strip, there is no impact on the yield and energy consumption in unit time, nor will it cause changes in current and output. Since the thickness of the feed zone exceeds the maximum starting point of the compression zone, the interval between the compression zone and the extrusion zone is constant without any change. In this way, with the increase of the feed quantity, the balance between the feed port and the discharge port is broken, and the feed port is larger than the discharge port. The material layer in the feeding area will accumulate and thicken until all the gaps and blocks are filled into the feeding port, so that the chip granulator cannot work normally. This will cause the phenomenon of braising.
  在木屑颗粒机的实际工作中,随着进给量的变化,主电机的瞬时输出和电流也发生相应的变化。此外,当进料厚度不超过压缩区起始点时,进料区材料层数越来越多的现象不会因为我们进料粉量的增加而产生。如前所述,能够引起瞬时输出和能量消耗变化的区域应该是与材料层相关的两个区域——压缩区域和挤压区域。因此,我们认为上述第三个领域——物质领域的合理存在是在一定条件下的。实际工作,也就是说,木屑颗粒机喂料层分布在压缩区,挤压面积和总厚度不超过压缩区ShiRu点补给区,木屑颗粒机可以正常工作在允许的权力,一旦喂养容量太大,超过厚度的压实面积的起点,材料层会堆积起来,然后逐渐增加,冠机颗粒机不能正常工作。但在正常和异常情况下,都存在上述三个区域的划分理论。
  In the actual work of the chip granulator, with the change of the feed rate, the instantaneous output and current of the main motor also change correspondingly. In addition, when the feeding thickness does not exceed the maximum starting point of the compression zone, the phenomenon of more and more layers of material in the feeding zone will not be caused by the increase of our feeding powder. As mentioned before, the area that can cause the change of instantaneous output and energy consumption should be two areas related to the material layer compression area and extrusion area. Therefore, we believe that the reasonable existence of the third field, the material field, is under certain conditions. The actual work, that is to say, the feeding layer of the sawdust granulator is distributed in the compression area, the extrusion area and the total thickness are not more than the Shiru point supply area of the maximum compression area, the sawdust granulator can work normally in the allowed power, once the feeding capacity is too large, the starting point of the largest compaction area exceeding the thickness, the material layer will pile up, and then gradually increase, the crown granulator can not work normally. However, under normal and abnormal conditions, there are three regional division theories mentioned above.
