The utility model discloses can monitor the liquid level of refrigerator cooling tower in real time, in time the alarm output signal to but remote control refrigerator cooling tower moisturizing motorised valve is in time opened or is closed, guarantees the relatively stable of cooling tower liquid level, makes operation and maintenance personal can in time know cooling tower liquid level state, thereby has stopped refrigerator cooling tower overflow or the emergence of water accident thanks to, has reliability height, remote monitoring, warning advantage such as timely.
Description
Technical field
The utility model belongs to cigarette machine electro-technical field, is specifically related to a kind of warning device carrying out observing and controlling for tobacco curing industry lithium bromide refrigerator cooling tower liquid level.
Background technology
In prior art, water is the important actuating medium of lithium bromide refrigerator cooling system, and in the lithium bromide refrigerator cooling tower course of work, some moisture vapour loss, a part is taken away by air owing to splashing.The cooling tower liquid level of the lithium bromide refrigerator of cigarette industry adopts ball-cock assembly to control, and after drip tray middle water level declines, ball-cock assembly is opened, by the timely moisturizing of filling pipe.When water level adds to desired location, ball-cock assembly is closed, and stops moisturizing.Because ball-cock assembly is short for serviceable life, caulking gum packing ring is often damaged, exist intake pressure contrary with ball float buoyancy direction, be not closed completely, water loss is serious, be difficult to shortcomings such as keeping in repair, often there is cooling tower spilling water phenomenon, cause water resource waste, and operating personnel can not actual liquid level in long-range understanding cooling tower, can not meet the demand of production and safety.
Utility model content
For the above-mentioned deficiency of prior art, the utility model will provide a kind of device for monitoring tobacco curing industry lithium bromide refrigerator cooling tower liquid level and report to the police, in order to ensure the relatively stable of cooling tower liquid level, make Operation and maintenance personnel can understand cooling tower fluid level condition in time, thus stop the generation of cryocooled tower spilling water or depletion accident, ensure that cooling tower runs well.
The technical solution of the utility model is: lithium bromide refrigerator cooling tower level monitoring warning device contains one or more cooling tower, an electric pole type level switch is set above the drip tray of each cryocooled tower, the output of level switch is connected with Programmable Logic Controller by I/O interface, Programmable Logic Controller output terminal is connected with alarm, described Programmable Logic Controller is also connected with cryocooled tower moisturizing motorized valve by I/O interface, is connected with host computer by Ethernet.This level switch arranges 5 electrode bar E1-E5 altogether, and wherein E5 is common electrode, and when the water surface reaches E2, cooling tower moisturizing motorized valve cuts out; When the water surface reaches below E3, cooling tower moisturizing motorized valve is opened; Due to some accident water surface drop to below E1 or drop to below E4 time, send full water or water Out alarm.
The utility model can be monitored the liquid level of cryocooled tower in real time, timely output alarm signal, and open in time by programmable controller Long-distance Control cryocooled tower moisturizing motorized valve or close, ensure the relatively stable of cooling tower liquid level, make Operation and maintenance personnel can understand cooling tower fluid level condition in time, thus stopped the generation of cryocooled tower spilling water or depletion accident, there is easy to operate, the advantage such as automatic water supplement, reliability are high, remote monitoring, warning are timely.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model control circuit figure.
Accompanying drawing 2 is the utility model mounting structure schematic diagram.
Accompanying drawing acceptance of the bid note is described below: 1-cryocooled tower; 2-electric pole type level switch; 3-Programmable Logic Controller; 4-alarm; 5-host computer; 6-moisturizing electric actuator, 7-drip tray.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.As shown in accompanying drawing 1 control circuit figure, lithium bromide refrigerator cooling tower level monitoring warning device contains one or more cooling tower 1, an electric pole type level switch 2 is set above the drip tray 7 of each cryocooled tower, the output of level switch is connected in order to send surveyed liquid level signal to Programmable Logic Controller by I/O interface with Programmable Logic Controller 3, one road output terminal of Programmable Logic Controller 3 is connected with alarm 4, Programmable Logic Controller is also connected with the moisturizing electric actuator 6 of cryocooled tower moisturizing motorized valve by I/O interface, Programmable Logic Controller communication port is connected with host computer by Ethernet.Electric pole type level switch set-up mode is as shown in accompanying drawing 2 mounting structure schematic diagram.This level switch arranges 5 electrode bar E1-E5 altogether, and wherein E5 is common electrode, when the water surface reaches secondary high water stage E2 place, cooling tower moisturizing motorized valve cuts out, the water surface reach time low-water level E3 sentence under time, cooling tower moisturizing motorized valve is opened, and ensures the relatively stable of cooling tower liquid level, due to some accident water surface be raised to full-water level E1 sentence down or drop to but below water level E4 time, Programmable Logic Controller 3 receives this signal, full water or water Out alarm is sent by alarm 3 after process, and the real-time status of each cooling tower liquid level of system can be controlled on dynamo-electric brain in section show with light beam form of icons, alarm 3 is audible-visual annunciator, all installation is had at operation room or scene, make Operation and maintenance personnel can understand cooling tower fluid level condition in real time and process in time, thus stop the generation of cryocooled tower spilling water or depletion accident, guarantee cooling tower runs well, improve the safe operation protection of refrigeration machine.The feature such as the utility model has that automatic water supplement, reliability are high, remote monitoring, monitoring alarm are timely.
