Abstract
The utility model discloses a liquid level monitoring and controlling device of a boiler condensate water recycling tank, and belongs to the technical field of cigarette electrical machines. The liquid level monitoring and controlling device comprises one or more condensate systems which are connected with the boiler condensate water recycling tank. The boiler condensate water recycling tank is connected with a pumping pipeline of a condensate water recycling water pump. The liquid level monitoring and controlling device is characterized in that a magnetic float level meter is vertically arranged on the side face of the boiler condensate water recycling tank and is electrically connected with a signal input end of a programmable logic controller, one output end of the programmable logic controller is electrically connected with a control end of the condensate water recycling water pump, and the programmable logic controller is further connected with a computer through a network. The liquid level monitoring and controlling device is reasonable in design, simple in structure, easy to implement and convenient to operate, and no blind area exists in the whole process of measuring. The liquid level monitoring and controlling device has the advantages of being clear in displaying, high in measuring precision and reliability, easy to observe, capable of analyzing the tendency of historical liquid level and the like.
Description
Technical field
The utility model belongs to the cigarette machine electro-technical field, is specifically related to a kind of for boiler being coagulated the device that water recovery tank carries out automatic measuring and controlling.
Background technology
In the prior art; the boiler of cigarette industry coagulates the water recovery tank tank level control system and adopts differential pressure transmitter to measure liquid level; it is big that reclaim the water yield, the variations in temperature of coagulating water summer; a jar interior temperature and pressure is changed greatly; actual condition in jar exceeds the measurement category of differential pressure transmitter, and the liquid level recovery control system is out of control, can not normally reclaim water with fixed attention; and the operative employee can't know a jar interior actual liquid level, can not satisfy and produce and safe demand.
The utility model content
Above-mentioned deficiency at prior art, the technical problems to be solved in the utility model provides a kind of boiler and coagulates the device that water recovery tank carries out automatic measuring and controlling, it can coagulate the water recovery tank liquid level to boiler in real time and monitor, in time export liquid level signal, and in time start by the programmable controller controls water pump, thereby realize that boiler coagulates the monitoring of water recovery tank liquid level.
The technical solution of the utility model is: a kind of boiler coagulates water recovery tank level monitoring control device, contain 1 and coagulate water to a plurality of steam generator systems, 1 coagulates water to a plurality of steam generator systems all coagulates water recovery tank with boiler and links to each other, boiler coagulates water recovery tank and is connected with the drinking-water pipe pipeline that coagulates water recovery water pump, and its special feature is: the lateral vertical that described boiler coagulates water recovery tank arranges a magnetic float liquid level gauge; Described magnetic float liquid level gauge is electrically connected with the signal input part of Programmable Logic Controller, and an output of described Programmable Logic Controller is electrically connected with the described control end that coagulates water recovery water pump, and described Programmable Logic Controller also links to each other with computer by network.
The utility model is reasonable in design, and is simple in structure, implements easily, and easy to operate, overall process is measured non-blind area, has clear display, certainty of measurement height, reliability height, observes easily, can advantage such as analyze to historical liquid level trend.
Description of drawings
Accompanying drawing acceptance of the bid keep the score state as follows: water coagulates in 1-system; 2-boiler coagulates water recovery tank; 3-magnetic float liquid level gauge; 4-Programmable Logic Controller; 5-coagulate water to reclaim water pump; 6-computer.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.As shown in Figure 1, native system arranges a magnetic float liquid level gauge 3 in the lateral vertical that boiler coagulates water recovery tank 2, magnetic float liquid level gauge 3 shows a jar interior actual liquid level in real time by magnetic float, liquid level teletransmission on the magnetic float liquid level gauge 3 simultaneously becomes send device output direct current signal (4-20) mA, link to each other with Programmable Logic Controller 4 by the I/O interface, Programmable Logic Controller 4 outputs with coagulate water and reclaim water pump 5 and link to each other, coagulate water when liquid level reaches the water level upper limit set value in boiler coagulates water recovery tank 2 and reclaim water pump 5 startup realization water recovery with fixed attention, water pump was out of service when liquid level was reduced to the water level lower limit set value in boiler coagulates water recovery tank 2.Described Programmable Logic Controller 4 also links to each other with computer 6 by the control net.Real-time and the historical trend of system's liquid level can show with diagrammatic form on computers, has improved the safe operation protection of boiler condensed water recovering system.The utlity model has characteristics such as simple in structure, easy for installation, that reliability is high, monitoring is timely.
