一、目的范围:用振动成型方法将糊料制成生阳极块。主要由成型给料系统、成型机、冷却输送系统组成。
二、成型采用三工位振动成型机,成型后经悬链进入冷却水池,出块时,检查表面质量,不合格的不进入下一道工序。
三、技术条件
1.成型温度:160±5℃。
2.振动时间:50~90秒。
3. 振动幅度:2~3mm。
4. 正常生产时偏心块偏心角90°、105°、135°,转速1800转/分。
5.生块体积密度:1.60g/cm 以上。
6. 炭块尺寸:1520×790×550±15mm、重量:1030Kg。
7. 产能:15~25块/小时。
四 、 操作前检查
1.设备启动前应清除转换档板、振动给料机、称量漏斗、压头上附着的料。
2. 检查液压油箱油位是否达到规定要求,油箱内严禁杂物混入,液压系统严禁漏油,打开液压油箱的冷却阀门。
3. 检查悬链各部件是否正常运行,润滑是否正常。
4.成型机各注油部位都要注设计维护规程要求使用的对号润滑油。
5.控制室内设定好称量漏斗称料量,设定好振动时间。
6.检查炭块冷却水池内水的液位,打开冷却水补充阀门。
7.设备运行前,对模具、重锤进行预热。
五、生产操作
1.成型机的操作在成型控制室内进行,分为自动和手动两种控制,在检修试车时,一定采用手动操作,正常生产时采用自动操作。
2.悬链系统可在现场操作箱上进行单体操作,也可以自控运行。
3.在开始生产时,糊料可能不合格,应将不合格料排出,不进入振型机内,糊料经检查合格后进入成型机成型。
4.成型操作应与混捏中控经常取得联系,注意沥青用量,混捏温度。
5.在生产操作中,应严密注视设备各部位运转情况及模拟板上的指示灯,注意电压、电流、液压温度、压缩空气、冷却水流量及压力等是否正常。
6.液压油应保持在30~40℃,不得超过50℃。
7. 棒孔内的冷却水应清理干净。
1. Scope of purpose: The paste is made into green anode block by vibration forming method. It is mainly composed of a molding feeding system, a molding machine, and a cooling conveying system.
2. The molding adopts a three-station vibration molding machine. After molding, it enters the cooling pool through the catenary. When the block is produced, the surface quality is checked, and the unqualified product will not enter the next process.
3. Technical conditions
1. Molding temperature: 160±5℃.
2. Vibration time: 50 to 90 seconds.
3. Vibration amplitude: 2~3mm.
4. In normal production, the eccentric angle of the eccentric block is 90°, 105°, 135°, and the rotation speed is 1800 rpm.
5. Bulk density of green block: above 1.60g/cm.
6. Carbon block size: 1520×790×550±15mm, weight: 1030Kg.
7. Capacity: 15-25 blocks/hour.
Four, check before operation
1. Before starting the equipment, the materials attached to the conversion baffle, vibrating feeder, weighing funnel, and indenter should be removed.
2. Check whether the oil level of the hydraulic oil tank meets the specified requirements. It is strictly forbidden to mix in the oil tank, and the hydraulic system is strictly forbidden to leak oil. Open the cooling valve of the hydraulic oil tank.
3. Check whether the various parts of the catenary are operating normally and whether the lubrication is normal.
4. Each oil injection part of the molding machine must be filled with the corresponding lubricants required by the design and maintenance regulations.
5. Set the weighing funnel weighing volume in the control room, and set the vibration time.
6. Check the water level in the carbon block cooling pool and open the cooling water replenishment valve.
7. Before operation of the equipment, preheat the mold and the heavy hammer.
Five, production operation
1. The operation of the molding machine is carried out in the molding control room, which is divided into automatic and manual control. Manual operation must be used during maintenance and test run, and automatic operation during normal production.
2. The catenary system can be operated individually on the on-site operation box, or it can be operated automatically.
3. At the beginning of production, the paste may be unqualified. The unqualified material should be discharged and not enter the vibrating machine. The paste will enter the molding machine after passing the inspection.
4. The molding operation should always contact the mixing and kneading control, pay attention to the amount of asphalt and the mixing temperature.
5. In the production operation, you should closely watch the operating conditions of each part of the equipment and the indicator lights on the analog board, and pay attention to whether the voltage, current, hydraulic temperature, compressed air, cooling water flow and pressure are normal.
6. The hydraulic oil should be kept at 30-40°C, not more than 50°C.
7. The cooling water in the rod hole should be cleaned up.
