Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steelmaking equipment, and particularly relates to a new device for monitoring oil leakage of a toothed roll thin oil station. Background Art
[0002] The toothed roll is the main equipment for shaft furnace production, mainly responsible for breaking and bearing the weight of pellet ore. The operation of the toothed roll is mainly completed by the action of the hydraulic cylinder. If there is serious oil leakage in the thin oil station, it will lead to insufficient oil volume in the hydraulic station, slow action of the hydraulic cylinder, and even more seriously, it will lead to inaction, pellet agglomeration in the shaft furnace, and cause production stoppage. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art, and provide a new device for monitoring oil leakage of a toothed roll thin oil station, which can monitor the oil volume in the thin oil station.
[0004] To solve the problems in the background art, the utility model adopts the following technical scheme: it includes a thin oil station, a liquid level sensor and a PLC control cabinet. The top of the thin oil station is provided with an opening for the liquid level sensor. A floating ball bucket is arranged inside the thin oil station. A number of through holes are opened on the outer wall of the floating ball bucket. The top of the floating ball bucket is connected to the inner wall of the top of the thin oil station, and the bottom of the floating ball bucket is connected to a contactor. A floating ball is arranged inside the floating ball bucket; the liquid level sensor is connected to the PLC control cabinet through a wire; the contactor is connected to an alarm through a wire, and the alarm is connected to the PLC control cabinet through a wire.
[0005] A oil pump is arranged at the top of the thin oil station. The oil pump is connected to an oil outlet pipe, and the oil outlet pipe is connected to the hydraulic cylinder of the hydraulic station. The hydraulic cylinder drives the toothed roll of the shaft furnace.
[0006] The beneficial effects of the utility model are as follows:
[0007] 1) Install a liquid level sensor to monitor the liquid level in the thin oil station in real time;
[0008] 2) Guide the monitoring signal to the monitoring screen of the PLC control cabinet, and at the same time add an alarm. When the oil level is lower than the lower limit, the alarm is activated;
[0009] 3) Monitor the data in real time, which is convenient for the on-site personnel to observe;
[0010] 4) Install an alarm bell, so that the on-site personnel can discover it in time, and cooperate with the maintenance personnel to handle it in time, reducing the failure time. Description of the Drawings
[0011] Figure 1 It is a schematic structural diagram of the utility model;
[0012] Figure 2 It is a schematic structural diagram of the floating ball bucket of the utility model. Detailed implementation mode
[0013] Referring to the figures, the specific implementation mode of the present utility model is as follows: It includes an oil thinning station 1, a liquid level sensor 4, and a PLC control cabinet 8. The top of the oil thinning station 1 is open and provided with a liquid level sensor 4. A floating ball bucket 7 is arranged inside the oil thinning station 1. A number of through holes 9 are opened on the outer wall of the floating ball bucket 7. The top of the floating ball bucket 7 is connected to the inner wall of the top of the oil thinning station 1, and the bottom of the floating ball bucket 7 is connected to a contactor 2. A floating ball 5 is arranged inside the floating ball bucket 7; the liquid level sensor 4 is connected to the PLC control cabinet 8 through a wire; the contactor 2 is connected to an alarm 6 through a wire, and the alarm 6 is connected to the PLC control cabinet 8 through a wire. An oil pump 3 is arranged at the top of the oil thinning station 1. The oil pump 3 is connected to an oil outlet pipe, and the oil outlet pipe is connected to a hydraulic cylinder of a hydraulic station. The hydraulic cylinder drives the gear roller of the shaft furnace.
[0014] When this new device for monitoring oil leakage in the gear roller oil thinning station is in use, an opening is made at the upper part of the oil thinning station 1 for the gear roller, and a liquid level sensor 4 is installed; cables are laid to the main control room of the shaft furnace (i.e., the PLC control cabinet 8) and the charging chamber, and an alarm 6 and a contactor 2 are installed. Power is led to the liquid level sensor 4 for power supply, and the feedback signal is detected and sent to the PLC control cabinet 8, and then enters the computer for programming. Combining the actual requirements of production and equipment, the lower limit alarm point is set. When serious oil leakage occurs in the oil thinning station 1, the liquid level sensor 4 detects the signal and feeds it back to the PLC control cabinet 8. When the oil level reaches the lower limit alarm point, the floating ball 5 moves downward and the contactor 2 acts to close, and the alarm 6 gives an alarm, completing the whole process from detection to signal feedback to alarm.
[0015] The floating ball 5 adopted is limited inside the floating ball bucket 7. The floating ball 5 can only move up and down inside the floating ball bucket 7. A number of through holes 9 are opened on the barrel wall of the floating ball bucket 7. Due to the fluidity of the oil, it will enter the floating ball bucket 7 to ensure that the liquid levels inside and outside the floating ball bucket 7 are the same. The floating ball 5 will rise as the oil level rises and fall as the oil level falls. When it drops to the warning point of the oil level, the floating ball 5 acts to close with the contactor 2 and alarms.
[0016] In summary, for this new device for monitoring oil leakage in the gear roller oil thinning station, a liquid level sensor is installed to monitor the liquid level in the oil thinning station in real time; the monitoring signal is guided to the monitoring screen of the PLC control cabinet, and at the same time, an alarm is added. When the oil level is lower than the lower limit, the alarm is activated; the real-time monitoring data is convenient for the post personnel to observe; an alarm bell is installed, and the post personnel can discover it in time and, in combination with the maintenance personnel, deal with it in time to reduce the fault time.
