Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of this utility model preferred embodiment.
Detailed description of the invention
The utility model will be further described below in conjunction with the accompanying drawings.
With reference to the accompanying drawings shown in 1, chemical industry dosing self-measuring device of the present utility model, it includes that reservoir 1, infusion pump 2, measuring tank 3, work tank 4, reservoir 1, infusion pump 2, measuring tank 3, work tank 4 are sequentially connected with by pipeline.Wherein, described measuring tank 3 is provided with the overflow regulation pipe group of adjustable metered liquid capacity, and overflow regulation Guan Zuyu reservoir 1 connects, and described overflow regulation pipe group is provided with the overflow sensor 5 that can control infusion pump 2 folding.
When chemical industry dosing, infusion pump 2 is run, and by pipeline, the liquid of reservoir 1 can be delivered to measuring tank 3.When the work liquid level of measuring tank 3 reaches set volume, unnecessary liquid level will produce overflow, and flow through overflow regulation pipe group, overflow sensor 5 sends overflow induced signal to infusion pump 2, thus control infusion pump 2 and quit work, the dosing having more is back to reservoir 1 through overfall 61 again, completes a dosing metering process with this.
With reference to shown in Fig. 1, refining further, described overflow regulation pipe group includes movable overflow pipe 6, fixed weir pipe 7.The mouth of pipe 71 that enters of fixed weir pipe 7 is in measuring tank 3, and the outlet spout of fixed weir pipe 7 is in reservoir 1 admittedly.Overflow sensor 5 is installed on fixed weir pipe 7 and is connected with infusion pump 2 signal.And movable overflow pipe 6 is on measuring tank 3 and can move up and down along the outer rim of fixed weir pipe 7.It is consequently formed adjustable metering overfall 61, the height of metering overfall 61 and the area of measuring tank 3, it is simply that dosing metered volume.
That is, movable overflow pipe 6, the respective outer side edges of fixed weir pipe 7 is utilized to realize overflow metering.Being embodied in, the size of measuring tank 3 is drawn by volume calculations formula (area × height).By the setting area of measuring tank 3, the preset height of overfall 61 can be calculated by dosing volume.As, overfall 61 moves to when entering at the mouth of pipe 71 of fixative flow tube along with movable overflow pipe 6, fixative flow tube enter the mouth of pipe 71 height, it is simply that the minimum dosing volume height of measuring tank 3；When overfall 61 be in movable overflow pipe 6 be connected maximum height with fixative flow tube time, here it is the maximum dosing volume height of measuring tank 3.
In a preferred approach, 1.5 times of design measuring tanks 3 of dosing volume are advisable.Therefore, measuring tank 3 can be designed to circular or square.And, can apply according to reality, configure the measuring tank 3 of correspondence for implementing material dosing the most of the same race, it is possible to achieve different material dosing mutually isolated, the suitability is strong, and practicality is high.
It addition, in practical operation, the design area of measuring tank 3, the height ratio of contact dosing volume, round numerical value and do scribe mark, to facilitate observation control.In the case of space allows, it is smaller that measuring tank 3 takes area, higher, and scribe mark, by larger, is so more beneficial for observing control.
With reference to shown in Fig. 1, refining further, the bottom land 31 of described measuring tank 3 has the port of export, the pipeline being connected between the port of export of measuring tank 3 with work tank 4 to be provided with electromagnetic valve 8.Electromagnetic valve 8 can be Non-follow control electromagnetic valve 8, or electromagnetic valve 8 forms automatic control system with cyclelog.
That is, after completing dosing metering, opens solenoid valve 8, measuring tank 3 turns on work tank 4, makes the dosing of measuring tank 3 be delivered on work tank 4.
Wherein, the tapered setting of bottom land 31 of described measuring tank 3, it is ensured that the dosing noresidue of measuring tank 3 every time, to avoid error in dipping；In practical operation, the actual metered volume of measuring tank 3 to count the pipe section before conical bottom part and electromagnetic valve 8, it is ensured that measuring accuracy.
Additionally, described measuring tank 3, movable overflow pipe 6, the fixed weir pipe 7 anticorrosion measuring tank that respectively employing acid and alkali-resistance material is made, anticorrosion movable overflow pipe, anticorrosion fixed weir pipe, adapting to the corrosion dosing of strong acid and strong base, such suitability is strong, safe and reliable.And overflow sensor 5 is set to photoelectric sensor, or it is ultrasonic sensor, or is liquid level sensor, to improve Automated condtrol.
