Description
The utility model relates to a kind of environment monitoring device.
The sewage of environment monitoring at present is sampled as manually and carries out, therefore the number of times of sampling is restricted, usually carry out the one or many sampling every day, with once or the sample of being got several times, sewage discharge situation according to assay explanation whole day, its shortcoming is that the sample of gathering has accidental life, and collected specimens and actual discharge sewage composition differ greatly, and cause result of laboratory test inaccurate.
The purpose of this utility model provide a kind of can be continuously, the round-the-clock equal proportion sewage sampling apparatus that the discharge of sewage of discharging is sampled of equal proportion automatically.
The utility model is by single-chip microcomputer, the control display panel, the sampling measuring cup, the sample storage container, sampling pump, the compound sample pump, stirring motor, draining bucket and solenoid valve are formed, be provided with single-chip microcomputer and digital display tube in the control casing on sampling apparatus top, the pipeline that links to each other with sampling pump is positioned at the top of measuring cup, the below of measuring cup is provided with the sampling solenoid valve, the sidepiece of measuring cup is provided with fluid level controller and seal cup, the bottom of device is provided with water butt, the draining bucket, the top of water butt is equipped with stirring motor and discharge solenoid valve, be provided with the compound sample pump in the water butt, the sampling pipe of compound sample pump is installed in the top of sampling cup, and sampling apparatus is arranged in the sampling casing.
The utlity model has the automaticity height, to need not the people on duty, can round-the-clock Continuous Tracking monitoring sampling, characteristics such as reduce labor intensity.
Accompanying drawing 1 is faced the inner structure synoptic diagram for the utility model.
Accompanying drawing 2 is looked the inner structure synoptic diagram for the utility model left side.
Below in conjunction with accompanying drawing the utility model is further described, sampling section of the present utility model is such, the sampling pump M in the sampling casing 13
1Link to each other with pipeline and be positioned at the top of measuring cup 3, pipeline with sewage by sampling pump M
1Sewage is collected in the measuring cup, the below of measuring cup is provided with sampling solenoid valve 4, the sidepiece of measuring cup is provided with fluid level controller 5 and seal cup 6, flow in the seal cup after the sewage that collects in the measuring cup overflows and flow in the draining bucket 8 and discharge, the photoelectricity level switch in the liquid-level controller (LLC) detects sewage sample in the measuring cup and reaches and set control sampling pump M after the liquid level
1Stop sampling, and open sampling solenoid valve 4 sample water in the measuring cup is released in the water butt 7, the top of water butt is equipped with stirring motor 9 and discharge solenoid valve, impeller on the stirring motor output shaft stirs to each water sample of gathering in the water butt, and by compound sample pump 10 and on sampling pipe 11 water sample is extracted in the sampling cup 12, be provided with single-chip microcomputer and digital display tube 2 in the control casing 1 on sampling apparatus top, but the program of setting in the single-chip microcomputer is sampled to sewage by the control motor of discharge of sewage equal proportion, and shows.
Principle of work of the present utility model is such, and equal proportion sampling is according to the discharge of sewage, with identical ratio, carries out the sewage sampling.For guaranteeing that the sample of being gathered is the equal proportion sample, this device will cooperate with sewage flowmeter, and sewage flowmeter inputs to one-chip computer with discharge of sewage signal, and one-chip computer is assigned the unitary sampling instruction according to flow to sampling apparatus.In addition, for guaranteeing equal proportion sampling, the sampling measuring cup imports sample at every turn and should be certain value, and the measure of being taked is that liquid-level controller (LLC) is set, and when the sewage in the sampling measuring cup rose to set liquid level position, controller produced signal, and sampling pump quits work.By above two links, sampling thief cooperates with sewage flowmeter realizes the sewage equal proportion sampling.
Its workflow is: guidance panel sampling ratio button, set sampling ratio and demonstration, with this signal input one-chip computer.Sewage flowmeter is the Sewage metering device, can measure sewage instantaneous delivery and integrated flow, and sewage flowmeter is delivered to one-chip computer with flow information.One-chip computer receives sampling ratio and flow information.Treatedly assign action command to sampling apparatus, sampling apparatus is pressed computer instruction work, and implementation status is fed back to computing machine, and under the control of computing machine, sampling apparatus is finished a series of actions of sampling automatically.
The equal proportion sampling implement body course of work can be divided into for three steps, and the first step is a unitary sampling, and second step was a mixed sampling.
Unitary sampling: after the start, according to the discharge of sewage, select suitable sampling ratio, the scaling signal that set this moment is sent into computing machine.Simultaneous computer receives the flow signal that sewage flowmeter is sent here continuously, and when flow reached the preset proportion value, computing machine was assigned action command to sampling apparatus, the sampling pump motor M
1The running sampling enters sampling measuring cup P through the sewer sewage sample
1The liquid level of sampling measuring cup constantly rises, and when reaching the control position, the microswitch action is sent the signal that puts in place, in view of the above to sampling pump M
1Assign halt instruction, meanwhile solenoid valve V
1Obtain open command, through 3 seconds time-delay rear electromagnetic valve V
1Conducting, sampling measuring cup P
1Sewage sample import sample storage container P
2, one time the unitary sampling process finishes.When the flowmeter flow value reached the ratio value of setting for the second time, computing machine was assigned the sampling instruction again.Repeat said process, finish unitary sampling for the second time.
Mixed sampling: by the sampling ratio that sets, the sewage sample of each unitary sampling gained all imports sample storage container P
2In, according to the sample time that sets, being generally 24h again, computing machine is assigned the sampling instruction, at first makes stirring motor M
3Running stirs compound sample.M
3Mixing pump M after the stall
2Work pumps into sampling cup P with certain compound sample
3Last compound sample pump outage, solenoid valve V
2Conducting will remain sewage and enter sewer, promptly be the equal proportion sample in the sampling cup, and the mixed sampling process finishes.
