Abstract
The utility model discloses an ammonia nitrogen titration bottle which comprises a cylindrical bottle body, an air vent arranged on an upper portion of the bottle body, a lower micro funneled opening, a short pipe extending into a bottle cavity and a long pipe with four ammonia outlets at a lower end. When the ammonia nitrogen titration bottle is used, a pH electrode is fixed onto the upper air vent for indicating titration end points, and two gradually contracting ammonia outlets perform a function of stirring during reaction, so that ammonia is fully absorbed and measuring results are accurate. In addition, the ammonia nitrogen titration bottle has the advantages of simple structure, low cost, safety in use, good cleaning effect and the like.
Description
Technical field
The utility model relates to a kind of water analysis and uses titration bottle, particularly relates to a kind of titration bottle of ammonia nitrogen automatic analytical instrument.
Background technology
At present, existing ammonia nitrogen titration method mainly contains colourimetry and electrode method, and corresponding titration apparatus is arranged respectively, and the feeding mode of ammonia has two kinds.A kind of is to feed ammonia from the top of titration vessel, and it is insufficient that the shortcoming of this method is that ammonia absorbs, and measuring error is bigger; Another kind is to feed from the bottom.Just be to use second method in disclosed in the patent 200910303619.9 " absorption cuvette and on-line monitoring titration method for ammonia nitrogen "; Yet also there are some defectives; If ventilation speed is too fast; It is insufficient that ammonia is absorbed, and the titration vessel are obturator, sets off an explosion easily if top pressure is excessive; Same gateway is used in the feeding of ammonia and the discharge of waste liquid, ammonia on maybe be before getting into the titration vessel by tube wall residual Liquid Absorption some, thereby the measuring error of causing; Vessel need be made with the good quartz glass of transparency, the shape more complicated of while bottle, and manufacture difficulty is big, so cost is higher.
The utility model content
Existing ammonia nitrogen titration vessel complex structure, cost are high in order to overcome, measuring error is big, ammonia absorbs deficiencies such as insufficient, the utility model provide a kind of simple in structure, cost is low, measurements is accurate, can stir, ammonia absorbs ammonia nitrogen titration bottle abundant, that cleaning is effective, safe in utilization.
The utility model solves the technical scheme that its technical matters adopted: a kind of ammonia nitrogen titration bottle; The cylindrical bottle that comprises both ends open; And stretch into a short tube and the long tube in bottle chamber, it is characterized in that: at the bottom of said long tube reaches bottle, and be two curved pipes to two reverse direction bifurcateds; The end of said curved pipe is diminishing opening, and the middle part has an aperture that Open Side Down respectively.
The point of crossing of short tube that said bottle top is passed and long tube and bottle wall is at sustained height, and two pipes form 120 ° of angles.
Said bottle open upper end is cylindrical, and lower ending opening is little infundibulate.
There is an aperture said bottle open upper end below.
The beneficial effect of the utility model is: titration bottle simple in structure, and cost of manufacture is low; A long tube is specifically designed to the feeding ammonia; And four outlets are arranged endways; Wherein two openings that shrink have gradually utilized the principle of shrink nozzle, and promptly air-flow can constantly quicken in the diminishing pipeline of sectional area, thereby gas reaches the purpose of stirring with bigger speed ejection; Ammonia is absorbed fully, and measurement result is accurate; The aperture on bottle top makes titration bottle become an open system, can not explode because internal pressure is big, has ensured operating personnel's safety; Lower ending opening is little infundibulate, and liquid circles round when feeding cleaning fluid, thereby cleaning performance is better.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of the utility model;
Fig. 3 is the fundamental diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As depicted in figs. 1 and 2, the ammonia nitrogen titration bottle of the utility model, its bottle 1 is cylindrical; The bottle upper end has cylinder open 3, lower end that little funnel-shaped opening 4 is arranged, and an aperture 5 is arranged near the upper shed 3; Bottle 1 top is passed a short tube 6 and a long tube 7 side by side and is put in the inner chamber 2; Long tube 7 reaches bottle body bottom and bifurcated is two curved pipes 8,9, and curved pipe 8,9 ends are the opening 10,11 that shrinks gradually, and the middle part has downward aperture 12,13 respectively.
The course of work of the ammonia nitrogen titration bottle of the utility model is: open upper end 3 is put into a pH electrode 14, injects absorption reagent from lower ending opening 4, and the ammonia in the cucurbit (not shown) is through long tube 7; And through abundant absorption of outlet 10,11,12,13 entering titration bottles quilts; Then from short tube 6 with vs, with pH electrode 14 indication titration end-points, reaction finishes the back from lower ending opening 4 effluent discharges; Inject distilled water from same opening again and clean titration bottle, prepare for measure next time.
Above embodiment is merely the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
Claims (4)
1. ammonia nitrogen titration bottle; The cylindrical bottle that comprises both ends open; And stretch into a short tube and the long tube in bottle chamber, it is characterized in that: at the bottom of said long tube reaches bottle, and be two curved pipes to two reverse direction bifurcateds; The end of said curved pipe is diminishing opening, and the middle part has an aperture that Open Side Down respectively.
