Waiting for the lifting skip to arrive, the quantitative bucket gate opens, all the coal slides straight to the lifting skip, the gate closes, and then the conveyor belt load is opened by the belt conveyor soft start device for the next loading cycle.
  • the other is the case where the conveyor belt conveyor without a fixed hopper is directly loaded into the lifting skip.
  • the working process is: a weighing device is provided at the lower part of the belt at the discharge point of the conveyor belt conveyor. After the conveyor belt conveyor is loaded with a lifting skip coal, Stop, lift the skip to the loading position, transport the belt conveyor, and then start it through the soft start device of the belt conveyor for the next loading cycle.
  • the length of the transport belt conveyor is generally 30 meters to 500 meters, and the drive motor power is 132kW to 2200kW.
  • the conveyor belt conveyor needs to be started under heavy load. Motors over 30kW are not suitable for frequent startup. It is common sense However, due to the current production process and equipment, the motor power of the conveyor belt conveyor used for coal mine production is 132kW to 2200kW. It can only be started by heavy load.
  • the starting current of the 132kW to 2200kW motor for heavy load is generally at the rated current 8-10 times, the mine voltage is generally 660V/1140V, the starting current peak value is at least 9000A-19200A, the main time of coal mine hoisting bucket is: when the belt is used to start loading, when the hoist bucket is used for lifting, each bucket is generally used in The belt motor starts about 60S and about 60s. Frequent excessive current causes the motor to continue to accumulate heat at high temperature, the insulation is reduced and burned, the grounding is broken, and the motor is burned out. The strong starting current damages the circuit switch, transformer and power grid. The serious failure occurred in about 10 days.
  • the belt motor was located at the throat of coal mine production. The motor burned down and the coal mine was shut down. Due to the harsh environment and the narrow site, frequent replacement of the motor caused a serious waste of manpower, material resources, and time. , And greatly reduced production efficiency;

  • the feeder in the first step does not have a weighing measurement device, the weight of the material cannot be weighed at the initial feeding point.
  • the weight of the material on the conveyor belt is too large .
  • Causing overload damage to the transport belt conveyor the use of large-scale, large feed volume and high-power transport belt conveyors is used on site. Because the width of the transport belt conveyor is large, it should increase the equipment investment and motor power. Excessive waste of energy consumption increases the excavation and construction costs of underground tunnels where large belt conveyors, high-power motors and large soft-start devices are placed.

Description

一种减少停机故障定量装载快速提升工艺方法及实现该方法的工艺装备 技术领域
本发明属于机械领域,具体涉及一种减少停机故障定量装载快速提升工艺方法及实现该方法的工艺装备。
背景技术
目前,定量装载提升系统主要有两种工作模式,一种是:有定量斗的情况,有定量斗、运输皮带机、皮带机软启动装置、给料机、提升箕斗、升降机等组成,其工作工艺是:运输皮带机先开动,给料机后开启,煤通过给料机给到皮带上,然后运输皮带机将煤输送到定量斗内,定量斗下部有称重传感器,到达设定重量,先停止给料机,再停止运输皮带机。等待提升箕斗到达,定量斗闸门打开,煤全部直溜到提升箕斗,闸门关闭,然后运输皮带机带载通过皮带机软启动装置开启,进行下一个装载循环。
另一种是无定量斗运输皮带机直接向提升箕斗装载的情况,其工作工艺是:在运输皮带机卸料点的皮带下部设置称重装置,运输皮带机装完一提升箕斗煤后停止,提升箕斗落到装料位置运输皮带机再行通过皮带机软启动装置开启,进行下一个装载循环。
以上装载方式的缺点是:
一、运输皮带机长度一般30米到500米,驱动电机功率在132kW到2200kW,每次停机后再行装载,都需运输皮带机重载启动,超过30kW的电机均不适于频繁启动是一般常识,然煤矿生产用的运输皮带机装载电机功率132kW到2200kW,由于受现有生产工艺及装备现状的限制,只能重载启动,重载启动的132kW到2200kW电机的启动电流一般在额定电流的8-10倍,矿用电压一般在660V/1140V,启动电流峰值至少在9000A-19200A,煤矿提升箕斗的用时主要有:皮带启动装载用时、提升箕斗提升用时,每提升一斗一般用时在60S左右,60s左右皮带电机启动一次,频繁超大的电流造成电机持续高温热量累计,绝缘降低烧坏,击穿接地,使电机短路烧毁,强大的启动电流对电路开关、变压器及电网都有损伤,该严重故障10天左右发生,该皮带电机所处位置是煤矿生产的咽喉部位,其电机烧毁造成煤矿停产,因环境恶劣,场地狭窄,频繁更换电机既造成了人力、物力、时间等的严重浪费,且大大降低了生产效率;
二、现有定量装载提升系统的给料机功率小,一般功率5.5kW-22kW,运输皮带机功率大,一般功率132kW-2200kW,而使用现场在运行中,装完一提升箕斗料后,既停止运输皮带机又停止给料机运行,造成大功率运输皮带机电机因频繁启动而经常烧毁,给料机功率虽然小于30kW,不会被很快烧坏,但因给料机装一提升箕斗料启停一次,增加了不必要的频繁启停,相 对减少了给料机的使用寿命;
三、提升箕斗到达装料位置运输皮带机开始重载启动,为了防止重载启动的运输皮带机电机很快烧毁,现都采用加装软启动装置的运输皮带机,既增加了制造成本,软启动开启速度慢,增加了装载耗时,严重降低了装载提升效率;
四、由于皮带下部设置的称重装置,受皮带频繁启动张紧力影响、侧向力影响、皮带跑偏打滑等影响,使称重装载严重不准,造成提升系统超载出故障,少装效率降低等,严重影响了安全生产及严重降低了整体效益的损失,
五、由于第一步给料的给料机无称重计量装置,在初始给料点无法称量所给物料的重量,为了防止物料洒落到运输皮带机下部,防止运输皮带机上的物料重量大,造成运输皮带机超载损坏,使用现场多选用大型号、大给料量、大功率的运输皮带机,因运输皮带机宽度大,故增加了装备不应有的过大投入,增加了电机功率过大的耗能浪费,增加了井下巷道为放置大皮带机、大功率电机及大型软启动装置的硐室开挖及建筑成本。
为了解决以上定量装载提升系统存在的问题,本发明提出了一种减少停机故障定量装载快速提升工艺方法及实现该方法的工艺装备。

本发明改变了旧式定量装载提升系统,运输皮带机先开动,给料机后开启,煤通过给料机给到皮带上,然后运输皮带机将煤输送到定量斗内,定量斗下部有称重传感器,到达设定重量,先停止给料机,再停止运输皮带机。等待提升箕斗到达,定量斗闸门打开,煤全部直溜到提升箕斗,闸门关闭,然后运输皮带机带载通过皮带机软启动装置开启,进行下一个装载 循环的工艺及装备,改变了无定量斗运输皮带机直接向提升箕斗装载的情况,在运输皮带机卸料点的皮带下部设置称重装置,运输皮带机装完一提升箕斗煤后停止,提升箕斗落到装料位置运输皮带机再行通过皮带机软启动装置开启,进行下一个装载循环的工艺及装备。
一、避免了运输皮带机的大功率驱动电机,每次停机后再行重载启动,启动电流峰值至少在9000A-19200A,频繁超大的电流造成电机持续高温,热量累计,绝缘降低烧坏,击穿接地,使电机短路烧毁,强大的启动电流对电路开关、变压器及电网都有损伤,其电机烧毁造成煤矿停产等严重损失;
二、将每60s左右皮带电机启动一次的状况改变为输送皮带机不停机连续运行,避免了因环境恶劣,场地狭窄,频繁更换电机,造成的人力、物力、时间等的严重浪费;
三、改变了装完一提升箕斗料后,既停止运输皮带机又停止给料机运行不必要的频繁启停,相对增加了给料机、运输皮带机的使用寿命;
四、免去了旧式定量装载提升系统所采用的软启动装置,既降低了制造成本,又免去了软启动增加的装载耗时,提高了装载效率;
五、改变了运输皮带机皮带下部设置称重装置的机构,避免了因受皮带频繁启动张紧力影响、侧向力影响、皮带跑偏打滑等影响,使称重装载严重不准,避免了提升系统超载出故障,少装效率降低等问题的发生,确保了安全生产及整体效益的提高,
六、改变了旧式定量装载提升系统,第一步给料的给料机无称重计量装置的结构,将称重计量装置组合在给料机上,在初始给料点称量给料,既防止了物料洒落到运输皮带机下部,又防止了运输皮带机上的物料不必要的重量过大,避免了运输皮带机超载损坏,改变了使用现场选用大型号、大给料量、大功率的运输皮带机,改变了因运输皮带机宽度大增加的装备不应有的过大投入,避免了电机功率过大的耗能浪费,避免了井下巷道为放置大皮带机、大功率电机及大型软启动装置,扩大井下硐室的开挖及建筑成本。
2.定量斗称重传感器称量左定量斗和/或右定量斗内的物料重量,并将称量数据传至称重计量给料机及控制装置,方便校核称重计量给料机的称重计量精度,使称重计量给料机给料更准确,方便控制装置在装载超载时启动安全保护措施。
3.皮带煤位传感器检测运输皮带机上的物料布置状态,避免因设备故障或各设备配合错误造成物料卸入井筒。
4.当提升箕斗装满料时箕斗料位传感器输出信号,防止物料从提升箕斗内溢出。
5.该系统使用带式旋连平除仓压全息称重计量给料机或胶链带旋连平除仓压全息称重计量给料机或链带式旋连平除仓压全息称重计量给料机,改变了将称重计量装置设置在运输皮带机卸料端的结构及称重方式,使用旋连平除仓压全息称重计量给料机,避免了胶带侧向力、 胶带跑偏打滑等对称重计量装置的干扰,确保了高质量称重给料,装载精准。

如图11和图12所示,一般称重计量给料机5和运输皮带机4的运量为每小时2000吨,提升箕斗2额定装载量为10吨,净提升用时为60秒,定量斗向提升箕斗2装料综合用时为6秒,每向上提升一提升箕斗物料的总用时为66秒,而66秒中称重计量给料机5的给料量为2000吨÷3600秒×66秒=36.7吨,故运输皮带机4的运输量是提升箕斗2的提升能力3.6倍,为使运输皮带机4和称重计量给料机5的计量运输量与提升箕斗2的提升量匹配,必须控制运输皮带机4和称重计量给料机5上的物料量,因此66秒期间称重计量给料机5的给料计量应为10吨,使运输皮带机4在66秒期间运输的物料重量为10吨额定装载量,使称重计量给料机5按一额定装载量给料后延时给料,使称重计量给料机5装一额定装载量加停止给料延时的总时间等于一提升箕斗2向上提升净时间加装料综合用时后,继续按称重计量给料机5装一额定装载量加停止给料延时的总时间等于一提升箕斗2向上提升净时间加装料综合用时工作,停止给料延时的时间大于或等于零,依序循环,具体操作工艺装备是:打开装料装置3的左溜槽8,开启运输皮带机4,开启称重计量给料机5,使运输皮带机4不停止运转,将该10吨额定装载量装入左定量斗10后即打开右溜槽9,给右定量斗11装料,同时,使左提升箕斗6到位,将左定量斗10内的10吨物料装入左提升箕斗6,左提升箕斗6提升,右定量斗11装满10吨额定装载量,打开左溜槽8,给左定量斗10装料,同时左右提升箕斗7到位,将右定量斗11内的10吨物料装入左右提升箕斗7,左右提升箕斗7提升,左定量斗10装满10吨额定装载量物料,打开右溜槽9,给右定量斗11装料,同时左提升箕斗6到位,将左定量斗10内的10吨物料装入左提升箕斗6,左提升箕斗6提升,右定量斗11装满10 吨额定装载量物料,打开左溜槽8,依序循环工作,确保运输皮带机4不停机运转,避免了运输皮带机4频繁重载启动,出现超大的电流造成电机持续高温热量累计,绝缘降低烧坏,击穿接地,使电机短路烧毁,避免了强大的启动电流对电路开关、变压器及电网都有损伤,使该严重故障10天左右发生的概率降低到一年以上都不会发生。避免了该皮带电机所处位置是煤矿生产的咽喉部位,其电机烧毁造成煤矿停产重大事故的发生,避免了因环境恶劣,场地狭窄,频繁更换电机既造成了人力、物力、时间等的严重浪费,本工艺装备的发明大大提高了生产一线的生产效率,确保了煤矿生产的安全节能。
