Abstract
The utility model discloses a liquid ammonia filling system. The liquid ammonia filling system comprises a filling hose and a liquid-filling clamp. The liquid ammonia filling system also comprises an electronic scale, a hanging balance device and a control part, wherein the hanging balance device is connected with the liquid-filling clamp in a hoisting mode; and a real-time weight signal of the electronic scale is received by the control part to automatically fill the liquid by controlling opening/closing of a liquid-filling valve. By adopting the special hanging balance device, the liquid-filling clamp is freely adjusted at a certain height, so that dynamic variation of a weight system is eliminated because of different heights to guarantee the accuracy of the weight of the liquid which is filled. The real-time weight signal of the electronic scale is received by a computer, and the opening/closing of the liquid-filling valve is controlled, so that the problem of liquid-filling automation is solved. The liquid ammonia filling system is convenient to operate, safe and stable; and in addition, the working efficiency is improved, the labor intensity of workers is lightened, the influence of personal factors is reduced, and the problems that the liquid ammonia at home is manually filled, the accuracy is low, the liquid ammonia is unsafely filled and the like are effectively solved.
Description
Technical field
The utility model relates to a kind of liquefied ammonia charging system, especially relates to a kind of liquefied ammonia automatic liquid feeding system.
Background technique
Liquefied ammonia is a kind of important chemical product, in refrigeration system, chemical fertilizer and other commercial production, purposes is widely arranged.This medium is at 10～15kg/cm
2Pressure under be in liquid state, have character such as burn into is explosive, that liquid ammonia steel bottle commonly used carries out is canned, transportation and using.Present on-the-spot liquid ammonia steel bottle fills and still adopts mechanical scale metering, manually opened valve topping up, the behindhand type of Spiral Steel Pipe resilient hanger anchor clamps; Operation inconvenience, automaticity is low, and precision is low; Dangerous, the bagging weight error is big, especially in summer; Because of liquefied ammonia is canned overweight, be prone to set off an explosion in transportation with in using.For this reason, being badly in need of advanced automatic canned system substitutes.
The model utility content
The utility model technical problem to be solved is the automation that liquefied ammonia fills, and the topping up anchor clamps are in the altitude range of regulation, and the position can be adjusted arbitrarily, eliminates topping up anchor clamps etc. automatically and is attached to the weight on the liquid ammonia steel bottle, guarantees to fill precision and topping up automation.
For solving the problems of the technologies described above; The utility model provides a kind of liquefied ammonia charging system, comprises filling flexible pipe, topping up anchor clamps, it is characterized in that: also comprise electronic scale, hanging balance device and control section; The hanging balance device lifting connects the topping up anchor clamps; Control section is used to receive the real-time weight signal of electronic scale, through the keying of control liquid-filling valve, realizes automatic liquid feeding.
Hanging balance device comprises column, crossbeam, counterweight, pulley and chain, and column is connected fixing with crossbeam, and pulley is located at the crossbeam two ends, and chain is walked around pulley one end and connected the topping up anchor clamps, and the other end connects counterweight.
Control section comprises central processing unit (CPU), program storage, data storage, liquid-filling valve, sound light alarming circuit, electronic scale interface circuit composition, and the weight signal that electronic scale takes by weighing steel cylinder inputs to central processing unit (CPU), is presented at weight signal on the display device in real time through extended chip; The weight signal that the keyboard input will fill also inputs to central processing unit (CPU), and output signal after program storage and data storage processing arrives output interface through extended chip; Opening of control liquid-filling valve, when topping up was accomplished, central processing unit (CPU) sent signal; Through extended chip, pass to output interface, control closing automatically of liquid-filling valve; Send acoustooptic alarm simultaneously; And central processing unit (CPU) output signal through level transferring chip, drives printer.
The utility model adopts special hanging balance device, realizes the freely adjustment of topping up anchor clamps on certain altitude, eliminates the dynamic variable quantity because of different its weight systems of anchor clamps height, to guarantee the accuracy of topping up weight.Utilize computer to receive the real-time weight signal of electronic scale, and control the keying of liquid-filling valve, solve the topping up automation issues.Easy to operate, safety and steady have improved working efficiency, have reduced working strength of workers and artificial factor, have solved present domestic liquefied ammonia effectively and have filled manually, hang down precision, uneasy congruent problem.
