我厂过滤系统的滤液原采用浮子杠杆机构的自动排液箱排除,原设计浮子是由6毫米普通钢板卷焊成,因严重锈蚀和矿浆的强烈冲刷损坏很快。后来,改用6毫米不锈钢板卷焊成,延长了浮子的使用寿命。但浮子杠杆机构仍然是比较笨重(重量40公斤),检修调整时,工人必须将气水分离器及两个排液箱的人孔盖全部打开,人进入排液箱内检修,不仅劳动强度较大,工作也很不方便。在生产过程中,经常因气水分离器底部、浮子顶部积矿、杠杆失灵、检修调整不当等原因,出现浮子不“倒班”现象。因此,造成矿浆进入真空泵、真空泵磨损严重,不仅增加备品备件的消耗和检修工作量,给过滤系统的生产带来了一定的影响。为此,我们和工人共同研究,以四通阀式排液器代替了原来
The original filtrate of the filtration system in our factory was eliminated by the automatic draining box of the float lever mechanism. The original design float was made of 6 mm ordinary steel coil welding, which was damaged by serious corrosion and strong erosion of the pulp. Later, the switch to 6 mm stainless steel coil welded to extend the life of the float. However, the float lever mechanism is still relatively heavy (weight 40 kg), maintenance adjustments, the worker must be the gas-water separator and two manhole cover drain tank all open, people into the drain tank overhaul, not only labor-intensive Large, work is also very inconvenient. In the production process, often due to the bottom of the gas-water separator, float the top of the deposit, the lever failure, improper maintenance adjustments and other reasons, the float does not “shift” phenomenon. Therefore, resulting in pulp into the vacuum pump, vacuum pump serious wear and tear, not only to increase spare parts consumption and maintenance workload, to the filtration system has brought some impact. To this end, we and workers to study together to replace the four-way valve drain the original
