Fig. 2 is a scheme of installation of giving drain pump automatically.
Embodiment
To combine accompanying drawing and specific embodiment that the utility model is done further explanation below.
The discolour silica gel drying agent is a blue particle, very easily absorbs moisture and graduates into pink, utilizes the characteristic of change color after its moisture absorption, uses as humidity indicator.And the degree size of making moist also can reflect basically, very intuitively very showyly just can differentiate.The silica-gel desiccant principal ingredient is SiO
2, outward appearance is that solid circles is spherical, through SiO
2Unique multi-cellular structure forms capillary and absorbs with coagulation and come the powerful moisture that absorbs, after the moisture absorption not deliquescence with product; Clean characteristics, it is widely used in the protection against the tide of various products such as electronics, electrical equipment, five metals, physical construction, food, medicine and light textile leather, also is the adsorbent of the unique contact of present FDA simultaneously.After using silica-gel desiccant replacement molecular sieve, before experiment, just can open-and-shutly know the state of instrument.
Its concrete connected mode a kind of drain pump of giving automatically as shown in Figure 2; Comprise solvent bottle 4, waste liquid bottle 6, agitated reactor 3 and control system; It is characterized in that said control system is connected through the flexible pipe 1 that is provided with elbow drying tube 5 with said solvent bottle 4; Said solvent bottle 4 is connected through flexible pipe 1 with said agitated reactor 3; Said agitated reactor 3 is connected through flexible pipe 1 with waste liquid bottle 6, and said waste liquid bottle 6 is connected through the flexible pipe 1 that is provided with elbow drying tube 5 with said control system, and said agitated reactor 3 is provided with straight drying tube 2; Be provided with blue diatom drying agent in said elbow drying tube 5 and the said straight drying tube 1.
Contrast experiment when making drying agent through the experimental data more than three batches and molecular sieve, sill is consistent as a result for both, conforms to quality requirements.Concrete data are following:
The full-automatic Ka Shi micro-water analyzer of table one: ZDJ-2S is measured head and is embraced gram oxime sheet midbody particle moisture report (using the discolour silica gel drying agent)
The full-automatic Ka Shi micro-water analyzer of table two: ZDJ-2S is measured head and is embraced gram oxime sheet midbody particle moisture report (use molecular sieve desiccant)
Can divide from the result of above-mentioned two groups of tables and to find out, measure basically identical as a result, all the conformance with standard regulation.Again from the experimental analysis Technology Need, the result precision that detects when using discolour silica gel, with a high credibility as drying agent.Though and the use molecular sieve is done the credible result of drying agent water content detection; But when external environment humidity alters a great deal; The non-water balance state that it can not effectively reflect instrument intuitively how; After in case humidity was invaded the molecular sieve drying layer, just can and connect flexible pipe 1 to expense Ti Shi test solution, methanol reagent, agitated reactor 3, waste liquid bottle 6 at once and cause non-isorrheic destruction, totally unfavorable to the experimental implementation of bottom.And the maintaining of giving instrument in the course of time increases a lot of troubles; Even can waste more expense Ti Shi test solution, methanol reagent; Increase unnecessary cost; The discolour silica gel drying agent graduates into pink for very easily absorbing moisture, when it during in straight formula drying tube 2,5 work of curved formula drying tube, utilize the pink characteristic of face after its moisture absorption; Pulverize is red or the part pulverize is red or be still blue particle to use the laboratory technician therefrom can naked eyes to tell the discolour silica gel drying agent as humidity indicator, thus correct the carrying out of decision experimental implementation.By shown in Figure 1, connect a kind of cassette micro-moisture tester during use, at first we are at Ka Shi liquid bottle; The methyl alcohol bottle, waste liquid bottle 6, the blue silica gel drying agent of dried is more finished changing in setting in the straight formula drying tube 2 on agitated reactor 3 tops, the curved formula drying tube 5; Pad one deck must be filled out with the medicinal cotton of dried in two of pipe, after installing according to existing method, and the interior environment weighing apparatus of operation total system earlier; Carry out the F value of the preparatory titration of moisture, drift value, blank moisture sample then successively; The test of testing sample, waste liquid and residual particles in the back cleaning reaction still that finishes are poured out the waste liquid in the waste liquid bottle; Soak the two platinum electrodes of maintenance with absolute methanol at last, cleaning experiment table top.Such experiment promptly finishes.Equipment after the improvement is handled easily both, and data are reliable, helps the maintaining of instrument, and saves cost.
