The present invention relates to the important component part of water quality online automatic detection analytical instrument, belong to the environment monitoring technical field, particularly is a kind of water quality online analyzer device reagent constant-current device.
(2) background technology
Existing water quality online automatic detection analytical instrument mainly comprises chemical oxygen consumption (COC) (COD) on-line automatic analyzer, ammonia nitrogen on-line determination instrument, total nitrogen on-line determination instrument and total phosphorus on-line determination instrument etc.All these water quality online analyzer devices all will be gathered various liquid reagents in the course of the work at regular time and quantity.The all ingredients jar generally all places the bottom of online analytical instrument.Method in common is the special-purpose small-sized peristaltic pump of every kind of reagent, and the reagent in each jar is promoted at regular time and quantity, is transported to the various jiggers at analytical instrument top.Major defect is: the failure rate of peristaltic pump is higher, accounts for 60%～70% of analytical instrument total failare rate; Pumping reagent enters jigger with the pulsatile impact state, the control of flow rate difficulty or ease, and general excess is overflowed more, causes reagent to waste in a large number; The peristaltic pump cost is higher, is generally imported product, and every more than 10,000 yuan.By retrieval, the water quality online analyzer device adopts the patent documentation of pumping reagent more, and wherein representative several pieces are: the method for on-line detector for COD (90102524), continuously detecting chemical total oxygen demand and device (94112025), chemical oxygen consumption (COC) in-line analyzer (97221292), online chemical oxygen demand (COD) analyser (98247842) and chemical oxygen consumption (COC) (COD) online automatic monitor (01204164).So far do not see that unpowered reagent is gathered patent documentation and technology is reported data.
(3) summary of the invention
In view of there is above-mentioned shortcoming in prior art, purpose of the present invention just is to provide a kind of water quality online analyzer device reagent constant-current device, solves two technical problem underlying.The first is no longer used pumping reagent, realizes unpowered automatic collection reagent; It two is that the reagent automatic constant current enters jigger, prevents from that reagent is excessive to overflow, and cuts the waste.Thereby overcome more above-mentioned shortcoming and defect parts of prior art.
Above-mentioned purpose is realized by following technical proposals:
Water quality online analyzer device reagent constant-current device comprises reagent pot, distilled water tank, underframe, liquid in-out flexible pipe and dividing plate.It is characterized in that this device is installed on the dividing plate in reagent storehouse of water quality online analyzer device upper top.Reagent pot wherein is placed on the underframe, and underframe is fixed on dividing plate right-hand part upper surface.Distilled water tank is installed in dividing plate left side upper surface.The liquid outlet of reagent pot and distilled water tank bottom all passes through the fluid flexible pipe, connects with the solenoid valve import of jigger under dividing plate top.Right-hand part is vertically installed process control plate below the dividing plate, on the process control plate from top to bottom, four solenoid valves, four jiggers, four solenoid valves are installed successively, are cleared up cup, well heater, solenoid valve, light inspection box and solenoid valve, and connect successively with the liquid in-out flexible pipe.Solenoid valve of rightmost connects with the water sample pump by the feed liquor flexible pipe in four solenoid valves in the top.
Reagent pot in the above-mentioned water quality online analyzer device reagent constant-current device is a round tube shape, glassware, horizontal laying.There is an inlet at rear portion above it, and there is a liquid outlet front portion below it.Insert a breather plug in its top inlet.
Breather plug on the mentioned reagent jar is that glassware comprises three sections.Its hypomere is elongated, and its stage casing is conical, matches with the inlet frosted of reagent pot, and its epimere be an oblateness.There is an air hole at its center.
After technique scheme enforcement, this constant-current device makes water quality online analyzer device inner structure layout more reasonable.Especially the reagent pot of this constant-current device and distilled water tank all place the upper top of analytical instrument, general knowledge according to " Water seeks its own level ", gravity by reagent and distilled water self, can flow into the jigger of its below automatically, so saved original many peristaltic pumps, significantly reduce the operation troubles rate, and reduced the instrument manufacturing cost.Also the inlet owing to reagent pot is not directly logical atmosphere, but inserts the breather plug of an above-mentioned special shape.When reagent when the jar lower liquid outlet flows out, outside air is not directly to enter the jar from inlet, but enters the bottom of jar interior reagent by the air hole on the breather plug, make a jar external and internal pressure equilibrium, stable, reagent keeps constant current, and metering easy to control can avoid a large amount of reagent to overflow waste.
