挖沙船输送带的设计细节

      挖沙船是一种水上采沙设备,经过挖沙船上洗砂设备的清洗可以得到高质量的河沙。经过挖沙船水洗后的河沙需要经过传送带的运输才能够输送到岸上。因此挖沙船的输送带是非常重要的部件,在输送带的设计方面,一定要注意一些细节。
     首先是挖沙船的输送带所输送的物料,在一般情况下,挖沙船需要考虑物料的一般特性、密度、最大粒度、有无油或化学药品等方面,以及挖沙船输送带的最大承载量或所需的最大输送能力、带宽以及带速等。其次对于挖沙船的输送机线路布置,要明确挖沙船沿输送机走向头、尾滚筒之间的距离。

挖沙船
      挖沙船输送机的驱动装置可分为单滚筒和双滚筒驱动,挖沙船如果为双滚筒驱动,则要注意电动机的总功率在第一和第二传动滚筒上的分配。另外还有输送带在传动滚筒上的包角,驱动装置位置,采用的起动形式等等。挖沙船输送机的滚筒直径需要根据输送带的实际要求来在确定。
      挖沙船输送机的托辊托辊形式,托辊直径,槽角;托辊间距,包括头部和尾部的过渡段长度。挖沙船输送机的给料装置形式,溜槽的个数,导料槽长度,缓冲托辊或缓冲架有无冲风吹草动,加料与带间的夹角。同时还需考虑拉紧装置的挖沙船形式、位置以及拉紧行程。

   Dredging sand is a kind of water-gathering equipment, washing sand washing equipment after dredging vessels can get high quality river sand. The river Sands washed by the dredging vessels need transport through the conveyor belts to be transported ashore. Therefore, dredging the conveyor belt is a very important part, in the conveyor belt design, must pay attention to some details.

挖沙船

   The first is the material transported by the conveyer belt of the dredging vessel, in general, dredging vessels need to take into account the general characteristics of the material, density, maximum granularity, oil-free or chemical, and the maximum carrying capacity of the dredging vessel, or the maximum transmission, bandwidth, and speed of the belt. Second, for the dredging of the conveyor line layout, to clear the dredging of the sand conveyor along the head, the distance between the tail drum.
   The driving device of dredging barge conveyor can be divided into single drum and double drum drive, and if it is a double drum drive, the total power of the motor is allocated on the first and second drive rollers. In addition, there are conveyor belts on the transmission drum, the driving device location, the starting form, and so on. The drum diameter of the dredging barge conveyor needs to be determined according to the actual requirements of the conveyor belt.
   The form of roller idlers of dredging barge conveyor, roller diameter, slot angle, idler spacing, including the length of the transition section of the head and tail. The feeding device of the dredging barge conveyor form, the number of chute, the length of the guide groove, the cushion roller or the buffer frame there is no rush, feeding and the angle between the belt. At the same time, we need to consider the type of dredging vessel, the position and the tension stroke.
