山东输送带皮带的撕裂有时候会发生,而且原因多样,当然我们都不想看到此类事故的发生,所以就需要做好预防措施,那么接下来,我们先来找找原因再根据原因做预防。
Shandong conveyor belt belt tearing sometimes occurs, and the reasons are diverse, of course, we do not want to see the occurrence of such accidents, so we need to do a good job of preventive measures, so next, we first find the cause and then according to the cause of prevention.
山东输送带皮带撕裂事故发生原因:
Shandong conveyor belt belt tearing accident causes:
输送物料中掺杂异物,如铁器、木棒等杂物,下落时对带体造成局部损伤,严重时直接穿透输送带并卡在漏斗、溜槽、机架或托辊上,输送带向前高速运转,使输送带发生纵向撕裂。
When the conveying material is mixed with foreign matter, such as iron, wood and other sundries, it will cause local damage to the belt body when falling. When it is serious, it will directly penetrate the conveyor belt and get stuck on the funnel, chute, frame or roller. The conveyor belt will run forward at high speed, causing longitudinal tearing of the conveyor belt.
物料中夹带有大块物料等,卡在漏斗挡板与缓冲托辊之间,或托辊架与回程段输送带之间,长时间划擦和卡压输送带,输送带表层一旦被刺破划伤则其伤口便会迅速加深,划透输送带,形成撕带。因而大块物料和所含异物是预防输送带撕裂的关键。
There are large materials embedded in the material, stuck between the funnel baffle and the buffer roller, or between the roller frame and the return section of the conveyor belt, scratching and clamping conveyor belt for a long time, once the surface of the conveyor belt is punctured and scratched, the wound will rapidly deepen, scratching through the conveyor belt, forming a torn belt. Therefore, removing large material and foreign matter is the key to prevent tearing of conveyor belt.
除了物料本身存在的威胁,在运送过程中,输送带本身物件脱落也是造成撕裂的一个主要原因。如振动器衬板、粉碎机锤头、落料口调节挡等脱落都有可能造成输送带撕裂。输送带直接压在支撑中间托辊的支架上,重载使输送带紧压支架,支架就像刀子一样划透输送带,造成撕裂。等等。
In addition to the threat of the material itself, in the process of transportation, the conveyor belt itself is a main reason for tearing. If the lining plate of vibrator, hammer head of crusher and adjusting block of falling mouth fall off, it may cause tearing of conveyor belt. The conveyor belt is directly pressed on the bracket supporting the middle roller. Heavy load makes the conveyor belt press the bracket tightly, and the bracket cuts through the belt like a knife, causing tears. And so on.
In order to prevent belt tearing of Shandong conveyor belt, the following measures should be taken:
从物料源头上加强控制,清理大块物料,增加除杂设备,降低异物和大块物料对输送带存在的威胁。加强检查,调高岗位巡检和点检的检查频度,做到问题及时发现、及时处理。
Strengthen control from the source of materials, clean up large materials, increase miscellaneous equipment, reduce the threat of foreign bodies and large materials to the conveyor belt. Strengthen inspection, adjust the inspection frequency of post inspection and professional spot inspection, so as to discover and deal with problems in time.
改善输送机结构,通过降低落料点落差,增加缓冲挡板,细物料先于大块物料落下等,减少冲击,降低物料速度,减少杂质插入输送带的可能性。增设撕裂检测装置,当输送带发生撕裂后,在更短的时间尽快检测出来,发出报警信号并且停机,尽量降低撕裂长度,减少损失。
Improve the structure of the conveyor, by reducing the drop point difference, increase the buffer baffle, fine materials fall before large materials, reduce the impact, reduce the material speed, reduce the possibility of impurities inserted into the conveyor belt. Add tear detection device, when the conveyor belt is torn, it will be detected as soon as possible in the shortest time, send alarm signal and stop, try to reduce tear length, reduce loss.
在输送带中加入带有闭合线圈的传感器,检测器安装在输送机的易撅裂部位,检测器连接在控制器上。输送带正常运行时,传感器经过检测器,检测器发出脉冲。当输送带撕裂,切断传感器线圈,传感器经过检测器时,检测器停止发出脉冲,控制器接受后,发出报警信号并停机。
A sensor with a closed coil is added to the conveyor belt, and the detector is installed on the easy cracking part of the conveyor, and the detector is connected to the controller. When the conveyor belt is running normally, the sensor passes through the detector, which emits pulses. When the conveyor belt is torn, the sensor coil is cut off, and the sensor passes through the detector, the detector stops sending pulses, and the controller receives the alarm signal and stops.
To prevent conveyor belt tearing accidents, in addition to taking preventive measures, it is necessary to strengthen the safety education of operation and maintenance workers, improve and perfect various management mechanisms, and make the conveyor better serve the production and improve the safety of production.
