Abstract

The utility model discloses an online water hardness tester, which comprises a peristaltic pump 14, an electric double three-way valve 20, a degassing three-way 19, mixing three-ways 15, 18, a colorimeter 16, a computer 17, etc., wherein, the computer 17 controls the electric double three-way valve 20 for locating a position, and causes the peristaltic pump 14 to rotate to pump sampling water, complex agent, color display agent and standard sample liquid to the mixing three-ways 15, 18 for mixing; the mixed liquids enter the colorimeter 16 for lighting intensity detection after degassed by the degassing three-way 9. The utility model can carry out one-way and two-way self test, water sample over proof standard alarm display, automatic printing of the test result for the sampling water, test result is exact, and operation is simple.

Description

A kind of water quality and hardness measuring instrument

The utility model relates to test instrumentation, relates in particular to the water quality and hardness measuring instrument.

Water hardness is to weigh the overall target that underwater gold belongs to ion concentration, and water hardness is big, easily makes gyp, influences the safe operation of boiler, generally all will soften processing to boiler feed water.So being carried out water quality and hardness measuring, the water after softening just seems extremely important, current, for the test of water hardness substantially all is that the laboratory is brought back in sampling in the water route after softening, adopt the electrode detection device to test or test with artificial titrimetry, the big operation of this detection error is cumbersome, can not carry out on-the-spot online check and analysis.

The purpose of this utility model provides a kind of being connected and directly detects water sample and hardness on the softening water route and exceed standard and report to the police automatically, detects data and handles automatically, the online water quality and hardness measuring instrument that testing result shows and prints.

In order to achieve the above object, the utility model adopts following structure, peristaltic pump is set in cabinet, the peristaltic pump entrance pipe is communicated with electric T-shaped valve, electronic pair of T-valve of electric T-shaped valve pipeline connection, electronic pair of T-valve pipeline is communicated with the standard sample jar, two sample water inlets are set on electronic two three road valves, the peristaltic pump inlet is gone back pipeline connection complexing agent jar and developer jar, the peristaltic pump export pipeline is communicated with the one-level mixing tee, one-level mixing tee pipeline connection secondary mixing tee, secondary mixing tee pipe kind are communicated with degassing threeway, and degassing triplate line is communicated with tintmeter, the COMPUTER CALCULATION machine also is set in cabinet, circuit connects peristaltic pump, electric T-shaped valve, the electronic pair of T-valve and tintmeter, and circuit connects printer, long-distance alarm apparatus and be arranged on digital display tube on the cabinet front.

During instrumentation, electronic pair of T-valve automatic localization of computer control turns to connects one road sample water inlet, and peristaltic pump is rotated, make tintmeter work simultaneously, after peristaltic pump rotates with sample water, standard specimen liquid, blank water, developer and comprehensive agent, mix by electronic pair of T-valve and electric T-shaped valve suction to mixing tee, mixed liquid is through after outgasing, enter tintmeter and carry out light intensity mensuration, measurement result shows by charactron, after finishing sampling determination, computing machine control once more peristaltic pump by electronic pair of T-valve seek the position turn to another road to take water inlet, carry out double sampling and measure demonstration, twice display result relatively, defective as water sample, computing machine will control warning lamp flicker and long-distance alarm apparatus toot cry to report to the police to measure and finish the back computer control and close peristaltic pump and tintmeter, and printing mensuration result of calculation and minute date.

Because the utility model has adopted aforementioned calculation machine control peristaltic pump to extract the blank water of sample water by electronic pair of T-valve, developer, complexing agent is after mixing tee mixes, through the tintmeter light intensity measure water hardness and as calculated machine handle the structure of measurement result automatically, make the utility model collection test chemical technology, the liquid tranmission techniques, the ray machine power technology is an one, the online single and double line that can realize water hardness detects monitoring automatically, testing result is accurate, water sample exceeds standard and reports to the police automatically, and the data presentation measurement result is printed automatically, and the utility model is simple to operate, adaptability is extensive, and is practical.

Below in conjunction with accompanying drawing in detail the utility model is described in detail

Fig. 1 looks cross-sectional schematic for the utility model structure master

Fig. 2 is the cross-sectional schematic of overlooking of Fig. 1

Fig. 3 is the utility model structure connection diagram

From Fig. 1 and Fig. 2, can find out, the utility model comprises cabinet 1, peristaltic pump 14, blank water pot 10, standard sample jar 9, chelating agent jar 11, developer jar 12, electronic pair of T-valve 20, electronic single T-valve 13, single card microcomputer 17, printer 2, charactron 3, tintmeter 16, Fig. 3 has then shown the connection schematic relationships of above-mentioned parts, when Push switch 8, after the instrument energized, charactron 3 shows the current time, printer 2 self checks, by reset key 5, printer 2 is got current time-division date and alarm parameters, proofreaies and correct alarm parameters by dial (of a telephone) 7, and instrument enters armed state, pressing start key 6 or instrument starts after 45 minutes automatically, instrument begins to detect, and single trigger electronic pair of T-valve 20 of 17 controls and electric T-shaped valve 13 are sought the position and turned to one road sample water inlet 15, after single trigger 17 control peristaltic pumps 14 rotate, sample water with one tunnel, standard sample liquid in the standard sample jar 9 and go into blank water in the blank water pot 10 by pipeline after electronic pair of T-valve 20 and electric T-shaped valve 13 are sucked into one-level mixing tee 15 and mix, enters secondary mixing tee 18, peristaltic pump 14 sucks secondary mixing tee 18 with developer and complexing agent simultaneously from developer jar 11 and complexing agent jar 12, warp is once mixing tee! 5 and the mixed mixed liquors of secondary mixing tee 18 through degassing threeways 19 degassings after, enter tintmeter 16 and carry out light intensity mensuration, and the bubble in the mixed liquor is discharged by evacuated tube, the mixed liquor that enters tintmeter 16 is measured the water hardness of sample water through tintmeter 16 light intensity, measurement result shows by charactron 3, after finishing one road sample water mensuration, single trigger electronic pair of T-valve 20 of 17 controls and electric T-shaped valve 13 are sought the position and are diverted to the mensuration demonstration that two road sample waters inlet 16 repeats double sampling water, twice test result single trigger 17 compares automatically, defective as water quality, single card microcomputer 17 will be controlled the long-distance alarm apparatus jingle bell and report to the police, and warning lamp 4 flickers on the cabinet show, after all mensuration is finished, single trigger 17 is closed peristaltic pump 14, tintmeter 16 is also controlled printer 2 and is printed mensuration result of calculation, and detection time, and the utility model also can detect the water hardness of wherein arbitrary road sample water separately by the program of adjusting single trigger 17.
