Abstract
The utility model provides an acrylic acid automatic transporting and metering device in polycarboxylate superplasticizer chemical synthesis. The acrylic acid automatic transporting and metering device comprises a metering scale and an acrylic acid storage plastic bucket arranged on the metering scale; the acrylic acid storage plastic bucket is connected with a preparation tank through a first pipeline; the preparation tank is connected with a vacuum buffer tank through a second pipeline; the vacuum buffer tank is connected with a vacuum pump through a third pipeline; the preparation tank is further provided with a fourth pipeline; and an air inlet valve is mounted on the fourth pipeline. Compared with the prior art, the acrylic acid automatic transporting and metering device solves the problems that manual metering and mechanical pump pumping of acrylic acid are high in labor intensity and potential safety hazards, can meter and control addition according to different needs, achieves transport, and is simple in operation, low in labor intensity, and high in efficiency and safety performance.
Description
Technical field
The utility model relates to a kind of vinylformic acid automatic vacuum metering e Foerderanlage, relates in particular to vinylformic acid vacuum automatic transport and measuring apparatus in a kind of polycarboxylate water-reducer chemosynthesis.
Background technology
At present, polycarboxylate water-reducer stoste mainly by use contain the Soxylat A 25-7 of unsaturated double-bond, the carboxylic acid (such as vinylformic acid, methacrylic acid etc.) that contains unsaturated double-bond is waited until by chemical polymerization.Vinylformic acid is a kind of main starting material at present, and moderate cost is widely used.Vinylformic acid belongs to strong acid, is liquid under the normal temperature state, and character is active, volatile and decomposition, and the gas of volatilization has irritating smell, has strong corrodibility.Vinylformic acid is stored in the plastic barrel, during use, generally adopts dual mode to extract; A kind of mode is that artificial method is poured out a certain amount of vinylformic acid, then adds in the preparing tank, and this mode hand labor amount is large, troublesome poeration, and also vinylformic acid splashes easily, has very large potential safety hazard; Another kind is to take mechanical pump from the plastics storage drum vinylformic acid to be extracted out, then pumps in the preparing tank.Adopt this mode, vinylformic acid has very large corrosion to pump and accessory, and in course of conveying, vinylformic acid flows in the pipeline of preparing tank through pump, and higher pressure is arranged, and causes easily in the connection of pipeline and pipe fitting and damages, vinylformic acid is revealed easily, has very large potential safety hazard.
Technical scheme
Goal of the invention of the present utility model provides vinylformic acid vacuum automatic transport and measuring apparatus in a kind of polycarboxylate water-reducer chemosynthesis, and it can measure and carry the mode that the vinylformic acid in the plastic barrel sucks by vacuum.
For solving the problems of the technologies described above, the technical scheme that the utility model is dealt with problems is: vinylformic acid vacuum automatic transport and measuring apparatus in a kind of polycarboxylate water-reducer chemosynthesis, the vinylformic acid that comprises weighing balance, is placed on the weighing balance is stored plastic tank, described vinylformic acid storage plastic tank is crossed the first pipeline and is linked to each other with preparing tank, this preparing tank links to each other with vacuum buffer tank by second pipe, vacuum buffer tank links to each other with vacuum pump by the 3rd pipeline, also be provided with the 4th pipeline on the preparing tank, the air inlet valve is housed on the 4th pipeline.
As preferably, on described the first pipeline the vinylformic acid open valve is arranged.
As preferably, the first bleed air valve is arranged on the described second pipe.
As preferably, on described the 3rd pipeline the second bleed air valve is arranged.
Compared with prior art, the utility model has solved the acrylic artificial weighing, mechanical pump extracts the problem that labour intensity is large, potential safety hazard is large of carrying.It can measure, control the different add-ons that need, and finishes conveying, and simple to operate, labour intensity is low, efficient is high, safety performance is high.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model.Vinylformic acid vacuum automatic transport and measuring apparatus are mainly by weighing balance 1 in this polycarboxylate water-reducer chemosynthesis, and vinylformic acid is stored plastic tank 2, preparing tank 7 formations such as grade.
Vinylformic acid is stored plastic tank 2 and is placed on the weighing balance 1, and weighing balance 1 shows the weight of acrylplastics bucket inner propene acid.Vinylformic acid is stored 2 barrels of mistakes of plastics the first pipeline 4 and is linked to each other with preparing tank 7, on the first pipeline 4 vinylformic acid open valve 3 is housed.Preparing tank 7 links to each other with vacuum buffer tank 12 by second pipe 9, and the first bleed air valve 10 is housed on the second pipe 9.
Set the vacuum tightness that vacuum pump will reach, open the 3rd valve 14, vacuum pump moves automatically, extracts the air in the vacuum buffer tank 12 out, keeps the certain vacuum tightness that reaches in the vacuum buffer tank 12.Close the 4th valve 6, open simultaneously the second valve 10, extract the air in the preparing tank out.After opening the first valve 3, automatically vinylformic acid is sucked preparing tank 7, at this moment, can determine required add-on according to the numeral that shows on the weigher.When reaching required amount, close the first valve 3, the second valve 10, to open simultaneously the 4th valve 6 and stop vacuum pump 15, this moment, vinylformic acid no longer entered preparing tank 7.
