Abstract
The utility model discloses a metering sampling device of an online automatic water quality COD (Chemical Oxygen Demand) monitor. The metering sampling device comprises a constant-flow air pump, a foreword/backward peristaltic pump, an inlet mouthpiece, an outlet mouthpiece, an overflow ventilation mouthpiece, a metering cup, a three-way electromagnetic valve and metering standard tubes, wherein the constant-flow air pump is connected with the normally closed end of the three-way electromagnetic valve; the common end of the three-way electromagnetic valve is connected with the overflow ventilation mouthpiece; the overflow ventilation mouthpiece is arranged on the metering cup; the inlet mouthpiece and the outlet mouthpiece both are arranged at the upper end of the metering cup and communicated with the inside and the outside of the metering cup; two metering standard tubes are arranged in the metering cup, and further connected with the inner ends of the inlet mouthpiece and the outlet mouthpiece, respectively; the metering standard tube connected with the outlet mouthpiece is shorter than the metering standard tube connected with the inlet mouthpiece; and the outlet mouthpiece is connected with the foreword/backward peristaltic pump. Compared with the prior art, the metering sampling device of the online automatic water quality COD monitor is capable of automatically performing accurate quantification on water applied without complex manual operations; and the workload is reduced and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of water quality detecting device, relates in particular to a kind of water-quality COD online automatic monitor metering sample feeding device.
Background technology
Water is Source of life, and the mankind be unable to do without water in life and activity in production, and quality and the human health of Drinking Water water quality are closely related.Along with the raising of socio-economic development, scientific progress and living standards of the people, people improve constantly the water quality requirement of Drinking Water, and water quality standard for drinking water is development and perfect correspondingly also.Because the many factors such as the formulation of Drinking Water water quality standard and people's habits and customs, culture, economic condition, scientific technological advance level, water resource and water quality present situation thereof are relevant, not only between various countries, and between the different regions of same country, the requirement of drinking water quality is all existed to difference.And in water-quality COD online automatic monitor in the prior art, sample water is measured when detecting, conventionally adopt the measurer containers such as measuring cup, graduated cylinder, yet operating process is loaded down with trivial details, inefficiency.
Utility model content
The purpose of this utility model provides a kind of water-quality COD online automatic monitor metering sample feeding device with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises constant flow gas pump, rotating peristaltic pump, import connects mouth, outlet connects mouth, overflow ventilation connects mouth, jigger, three-way solenoid valve and metering mark pipe, described constant flow gas pump is connected with the normal-closed end of described three-way solenoid valve, the common port of described three-way solenoid valve connects mouth with described overflow ventilation and is connected, described overflow ventilation connects mouth and is arranged on described jigger, described import connect mouth and described outlet connect mouth be all arranged at described jigger upper end and with described jigger in be interlinked to the outside, described metering mark pipe is two, two described metering mark Guan Jun are placed in described jigger and connect mouth with described import respectively and are connected with the inner that described outlet connects mouth, connect described metering mark pipe that mouth is connected than to connect the described metering mark pipe that mouth is connected short with described import with described outlet, described outlet connects mouth and is connected with described rotating peristaltic pump.
The beneficial effects of the utility model are:

Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-constant flow gas pump, 2-rotating peristaltic pump, 3-import connect that mouth, 4-outlet connects mouth, 5-overflow ventilation connects mouth, 6-jigger, 7-three-way solenoid valve, 8-metering mark pipe.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises constant flow gas pump 1, rotating peristaltic pump 2, import connects mouth 3, outlet connects mouth 4, overflow ventilation connects mouth 5, jigger 6, three-way solenoid valve 7 and metering mark pipe 8, constant flow gas pump 1 is connected with the normal-closed end of three-way solenoid valve 7, the common port of three-way solenoid valve 7 connects mouth 5 with overflow ventilation and is connected, overflow ventilation connects mouth 5 and is arranged on jigger 6, import connect mouth 3 and outlet connect mouth 4 be all arranged at jigger 6 upper end and with jigger 6 in be interlinked to the outside, metering mark pipe 8 is two, two metering mark pipes 8 are all placed in jigger 6 and connect mouth 3 with import respectively and are connected with the inner that outlet connects mouth 4, connect metering mark pipe 8 that mouth 4 is connected than to connect the metering mark pipe 8 that mouth 3 is connected short with import with outlet, outlet connects mouth 4 and is connected with rotating peristaltic pump 2.
As shown in Figure 1: rotating peristaltic pump 2 forwards surpass the high-end of metering mark pipe 8 by the quantitative reagent pump of needs to 6 li of jiggers reagent liquid level; 2 reversions of rotating peristaltic pump, pump the reagent of 6 li of jiggers, until reagent liquid level arrives the high-end of metering mark pipe 8; Three-way solenoid valve 7 energisings are opened normal-closed end and are closed Chang Kaiduan, constant flow gas pump 1 energising, air-flow is flowed to jigger 6 and is produced normal pressure by three-way solenoid valve 7 normal-closed ends, and normal pressure connects the whole sample introductions of realizing reagent that extrude of mouth 4 by the reagent between metering mark pipe 8 high low sides in jigger 6 inner chambers by outlet; The metering volume that regulates the poor realization of metering mark pipe 8 high low side to need.
