Description
Technical field
the utility model relates to a kind of accurate measurement aluminium liquid level detection system.
Background technology
for aluminium alloy casting industry, generally holding furnace or machine limit are dissolved holding furnace and die casting machine is set together, aluminium liquid is provided to die casting machine by holding furnace or machine limit dissolving holding furnace moment, by continuous production and application, aluminium liquid in holding furnace stove gradually reduces, and now needs in holding furnace stove, to join soup or throw aluminium ingot in dissolving holding furnace stove to dissolve; But when joining soup or throwing aluminium ingot, Die Casting producer is undertaken observing and judging by human eye greatly, very easily causes the situation of the excessive use of aluminium liquid when manufacturer's equipment is too much or operating personnel neglect.
meanwhile, in order to stop to join, soup is excessive and to add aluminium ingot excessive, and holding furnace on the market or machine limit are dissolved holding furnace major part and all configured fixed upper limit level detecting electrode, for reporting to the police when aluminium liquid liquid level is completely measured at present; But join soup operating personnel or throw aluminium ingot personnel and be difficult to grasp and join soup amount or add aluminium ingot amount, therefore often stop again joining soup or adding aluminium ingot after aluminium liquid liquid level detection electrode is reported to the police, at this moment aluminium liquid liquid level is excessive, but speed of production is certain, therefore aluminium liquid liquid level detection electrode head is immersed in aluminium liquid always, is easy to by the active aluminium corrosion of chemical property.
Utility model content
in order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of accurate measurement aluminium liquid level detection system, automatically can detect aluminium liquid liquid level, can also extend the probe life-span.
the purpose of this utility model realizes by the following technical solutions:
a kind of accurate measurement aluminium liquid level detection system; comprise PLC, display, protective layer, for detect aluminium liquid liquid level position probe and for driving the driving mechanism of the vertical movement of probe; the shift position of probe comprises minimum liquid level from the bottom to top, the highest liquid level and guard bit; driving mechanism is fixed on protective layer; protective layer has the passage for the protection of probe; guard bit is located in this passage; probe is threaded with the output of driving mechanism, and PLC is electrically connected display and driving mechanism respectively.
preferably, driving mechanism is the electric cylinder of cylinder, oil cylinder or band encoder.
preferably, also comprise protective cover, PLC, display, driving mechanism, probe protected cover shroud is interior.
compared to existing technology, the beneficial effects of the utility model are:
1. adopt can the electric cylinder of Precision measurement position or cylinder (band encoder or electronic ruler) for the utility model, the aluminium liquid height of any time can be detected and calculate the parameters such as the consumption of aluminium liquid in conjunction with PLC in real time, show in the display simultaneously, greatly facilitate the automation mechanized operation of production;
2. probe of the present utility model adopts and is threaded, and replacing is convenient and cheap.
probe of the present utility model adopts moveable mode to detect, probe without the need to aluminium liquid Long Term Contact, improve the life-span of probe.
Accompanying drawing explanation
fig. 1 is a kind of structural representation of accurate measurement aluminium liquid level detection system.
in figure: 1, protective cover; 2, driving mechanism; 3, cylinder holder; 4, probe; 5, conductive lever; 6, PLC; 7, display; 8, protective layer; 81, passage.
Detailed description of the invention
below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
a kind of accurate measurement aluminium liquid level detection system as shown in Figure 1, comprise PLC 6, display 7, protective layer 8, for detect aluminium liquid liquid level position probe 4 and for driving the driving mechanism 2 of the vertical movement of probe 4, the shift position of probe 4 comprises minimum liquid level from the bottom to top, the highest liquid level and guard bit, driving mechanism 2 is fixed on protective layer 8, protective layer 8 has the passage 81 for the protection of probe 4, guard bit is located in this passage 81, probe 4 is threaded with the output of driving mechanism 2, PLC 6 is electrically connected display 7 and driving mechanism 2 respectively.
as one preferred embodiment, driving mechanism 2 is the electric cylinder of cylinder, oil cylinder or band encoder.
as one preferred embodiment, also comprise protective cover 1, PLC 6, display 7, driving mechanism 2, probe 4 protected cover 1 shroud, interior, can prevent aluminium liquid from splashing and damage native system.
driving mechanism 2 i.e. electric cylinder or cylinder (band encoder or electronic ruler) are fixed on electric cylinder or cylinder holder 3, and namely cylinder is fixed on protective layer 8 by cylinder holder, and cylinder moves up and down under the control of PLC.It should be noted that the mode of PLC 6 control cylinder 2 movement or control conventional drive mechanism and carry out the method that moves linearly, be prior art, the utility model directly have employed PLC control method conventional at present.The guard bit of probe, the highest liquid level and minimum liquid level is set according to the difference of installation site; make native system can detect the highest liquid level and minimum liquid level simultaneously; and any liquid level that can detect in the highest liquid level and minimum liquid level, solve all unfavorable factor in the past leaning on eye-observation liquid level to bring.
in use procedure, the frequency of soup Speed Setting probe decline detection is on average got according to die casting machine, in use procedure, device decline at regular intervals detects, at once retract after probe 4 touches aluminium liquid liquid level, prevent the continued oxidation of probe from corroding, simultaneously by the encoder of driving mechanism 2 or the amount of moving down relatively of electronic ruler measuring probe 4, and the amount of moving down Signal transmissions is calculated to PLC 6, subsequently aluminium liquid in stove use amount and the Signal transmissions such as time that can also maintain production are carried out display to display 7 to circulate a notice of, be used to guide production.
wherein, probe is positioned at flame retardant coating and the protective layer of bell in a large amount of not duty cycles always, is protected by flame retardant coating; that is the probe face time is very short; therefore the chance contacted with aluminium liquid is little, so the probe life-span is very long, is about common fixed more than 3 times.
probe 4 can be adopted as exploring electrode, and it realizes being threaded by stainless steel conductive lever 5, nut connection, and when electric cylinder or cylinder (band encoder or electronic ruler) move, the motion of rise and fall is done by whole mechanism.Displacement is sent to PLC 6 and accepts its control by electric cylinder or cylinder (band encoder or electronic ruler) in real time, and PLC 6 is by corresponding data display on the display 7 simultaneously, for real-time prompting aluminium liquid height and prompting when join soup or add aluminium ingot.The utility model automaticity is high, and highly intelligence, makes associated production personnel can control productive temp very clearly and make corresponding warming-up exercise.
to one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
