The utility model aims to provide a monitoring system which does not need manual measurement and indoor calculation, can realize automatic acquisition of multi-point settlement of a foundation, and can calculate differential settlement of associated points.

This utility model relates to a lubrication device for a down-the-hole drill hoisting system, belonging to the field of mining equipment technology in the metallurgical industry. The technical solution is as follows: the bottom sprocket (7) and the top sprocket (9) are respectively fixed on the drill frame (12), and the bottom sprocket (7) and the top sprocket (9) are connected by a hoisting chain (6). The pressure sprocket (3) cooperates with the hoisting chain (6). The lubricating oil tank (1) is located above the pressure sprocket (3). The upper end of the oil dripping pipe (15) is connected to the bottom of the lubricating oil tank (1), and the lower end of the oil dripping pipe (15) faces the pressure sprocket (3). One end of the high-pressure air pipe (5) is connected to the air compressor (17), and the other end of the high-pressure air pipe (5) faces the bottom sprocket (7). An adjusting valve (2) is installed on the oil dripping pipe (15), and an air pipe valve (8) is installed on the high-pressure air pipe (5). The beneficial effects of this utility model are: ensuring the lubrication of the hoisting chain, and using high-pressure airflow to remove mineral powder on the sprocket and chain, avoiding grease splashing.

The application provides a dry pulverized coal gasifier multi-pulverized coal line conveying automatic control method and device, which comprises the following steps: receiving various constraint conditions input on a DCS operation interface; collecting operation data of each coal preparation line and operation data of each gasifier; determining to start a single coal preparation line or two or more coal preparation lines for pulverized coal conveying according to the constraint conditions, the operation data of each coal preparation line and the operation data of each gasifier; if the single coal preparation line is started for pulverized coal conveying, a pre-set single coal preparation line conveying strategy is executed; if two or more coal preparation lines are started for pulverized coal conveying, a pre-set two or more coal preparation line conveying strategy is executed. Thus, the self-identification and selection of the coal preparation line can be realized, the pulverized coal conveying to the gasifier is fully automatically controlled, the human intervention is reduced, the timeliness and accuracy of the human judgment are avoided, and the safety of the pulverized coal conveying is significantly improved.

The application relates to an intelligent infusion device, which comprises a monitoring box, a display instrument panel, a starting switch and an adjusting knob, the display instrument panel, the starting switch and the adjusting knob are arranged on the side wall of the monitoring box, a supporting hook is arranged on the upper end surface of the monitoring box, an intelligent infusion mechanism is arranged on the lower end surface of the monitoring box, an infusion hose is arranged on the intelligent infusion mechanism, and a flow rate regulator is arranged on the infusion hose. The intelligent infusion device can avoid the problem that the existing infusion process cannot timely replace the bottle, so that the working strength of nursing staff can be reduced in the actual working process, and the time reminding function can be realized after the infusion is completed, so that the nursing staff can timely obtain the effect that the infusion is completed, and the nursing staff can timely replace the bottle, thereby avoiding the problem of medical disputes.

This utility model relates to the field of chemical production and processing technology, specifically an automatic dispersant dosing device. It includes a dispersant dosing unit, a reaction unit, and a washing unit. The dispersant dosing unit includes a dispersant hopper, with a dispersant tipping machine connected to the bottom of the hopper, and a dispersant screw conveyor connected to the bottom of the tipping machine. The reaction unit includes a sodium sulfide solution preparation tank and a dispersant solution preparation tank, with the upper part of the sodium sulfide solution preparation tank connected to the sodium sulfide solution tank via a pipeline. In this automatic dispersant dosing device, the dispersant hopper, dispersant tipping machine, and dispersant screw conveyor, in conjunction with a level gauge and a PLC automatic control system, achieve automatic and precise dispensing of the dispersant. The tipping machine shaft and rake teeth of the dispersant tipping machine effectively prevent material blockage, while the screw conveyor shaft and blades of the dispersant screw conveyor ensure stable material transport, avoiding errors and delays associated with manual dosing.
