Description
Technical Field
The utility model relates to a weighing alarm and recovery device for leakage of a carrier roller bearing lubrication pipeline of a sintering circular cooler, and belongs to the technical field of sintering circular coolers.
Background
Some large steel factories generally have sintering circular cooling lines, a plurality of groups of supporting roller devices are arranged on the production lines, each roller is heavy in dead weight and needs to bear a large load during working, and therefore bearings at the supporting rotating parts of the roller devices need to be filled with lubricating grease in a timing and quantitative mode to ensure reliable operation. At present, the traditional grease filling mode is finished by means of a set of time-controlled automatic oil supply system, and the system consists of an oil storage tank, an oil supply pump, a motor, a pipeline, an electromagnetic reversing valve, a pressure sensor and the like. The pump motor rotates normally when the system is in normal operation, and the pump motor is stopped unless the pressure sensor at the tail end of the main pipe detects the overpressure of the system. Each group of carrier roller devices is generally provided with five lubrication points, and one production line is generally provided with five groups of carrier roller devices, so that each group of carrier roller devices is provided with a valve box, and five two-position two-way (normally closed) electromagnetic reversing valves are arranged in the valve box to control the lubrication of each lubrication point. All electromagnetic reversing valves of each valve box of the whole set of lubricating system are powered on at the same time every one hour, and grease is shunted from a main pipeline to each branch pipe and finally enters each lubricating point. The time for filling grease generally lasts five minutes, and after the time is up, the solenoid valves of the valve boxes are controlled by the time relay to be simultaneously powered off so as to cut off the oil supply. The traditional lubrication oil supply system often has leakage phenomenon at the joint part of the pipeline which is branched off by the main pipe and enters the branch pipe of each valve box after long-time operation, and the leakage phenomenon frequently occurs after a period of time although equipment maintenance personnel fasten or replace the joint at the joint part. Because the time of oil leakage is not fixed, the position is also not fixed, and the workshop needs to input a large amount of manpower and frequently patrol and examine the state of each easy leakage point, once leakage occurs at the night that workshop production is busy or unmanned on duty, oil can pile up subaerial near the leakage point in a large number, causes site pollution, oil waste, induces the potential safety hazard that personnel slided.
Meanwhile, once leakage occurs, the oil pressure at all lubrication points in the pipeline can be reduced, and grease at the lubrication points cannot enter a lubrication area, so that serious abnormal sound and clamping stagnation phenomenon occur when the carrier roller rotates, and further the production efficiency and the progress of the production line are affected. The reason for the situation is that the medium used in the original lubrication system is grease such as lithium grease, the viscosity of the medium is high, if the pipeline is long and each lubrication point needs to be fully lubricated, high system pressure needs to be provided, the pressure pulsation and impact phenomenon are serious at the position of the main pipe to the branch pipe joint position due to the change of the pipe diameter, and the frequent switching of the lubrication point reversing valve, meanwhile, vibration during the running of the annular cooler can be transmitted to the pipeline at the position, and the joint position at the position is easy to loosen due to the comprehensive effect of all internal and external factors, so that the grease is leaked.
