Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a conventional mixing tank apparatus.

As shown in fig. 1, the conventional mixing tank apparatus includes a mixing tank 1, a pump 2, an elevated tank 4, and a synthesis tank 3. The mixing kettle 1 is communicated with the elevated tank 4 through a pipeline 5, the pump 2 is arranged on the pipeline 5, the pipeline 5 is also provided with a first valve 6 and a second valve 7, and the pump 2 is positioned between the first valve 6 and the second valve 7 and is arranged close to the first valve 6.

When the existing mixing kettle equipment is used, the mixed liquid which is prepared quantitatively is uniformly mixed through the mixing kettle 1, then the first valve 6 and the second valve 7 are opened in sequence, the mixed liquid which is uniformly mixed is pumped to the elevated tank 4 through the pipeline 5 by the pump 2, and the mixed liquid enters the synthetic product of the synthesis kettle 3 from the elevated tank 4.

It can be easily found from the above description that when the existing mixing kettle equipment is used, a certain amount of mixed liquid is easy to remain in the pipeline 5 leading to the elevated tank 4, and thus, when the existing mixing kettle equipment is used, data errors are easy to cause, and the quality of the synthesized product is unstable. Therefore, the embodiment of the utility model provides a mixing kettle equipment of accurate measurement.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a mixing tank device with accurate metering according to an embodiment of the present invention.

As shown in fig. 2, the mixing tank apparatus with accurate metering comprises all the structures of the prior mixing tank apparatus, a water pipe 8 is connected to the position of the pipeline 5 between the first valve 6 and the pump 2, the end of the water pipe 8 far away from the pipeline 5 is connected to a water source, a flow meter 9 and a third valve 10 are arranged on the water pipe 8, and the third valve 10 is arranged between the flow meter 9 and the pipeline 5 and close to the pipeline 5.

The pump 2 and the first valve 6 are in a low position relative to the second valve 7, so that the newly added water line 8, the flow meter 9 and the third valve 10 are also in a low position relative to the second valve 7. The pump 2 is a gear pump. The flow meter 9 is a mass flow meter. The first valve 6, the second valve 7 and the third valve 10 are all electronic valves, and when the electronic valves are used in cooperation with a controller, automation is easy to realize.

The utility model provides an accurate measurement mixing kettle equipment when using, the mixed liquid that the ration was joined in marriage mixes the back evenly in mixing kettle 1, make mixing kettle 1 stop the stirring, then open first valve 6 and second valve 7 in proper order, the starting pump 2 pumps the mixed liquid of misce bene to elevated tank 4 through pipeline 5 for subsequent use, there will be not few mixed liquid in the pipeline 5 at this moment, the total amount that causes to drop into in mixing kettle 1 and the total amount of squeezing into elevated tank 4 differ by several hundred kilograms, calculate the dispersion of difference according to pipeline 5 length and sectional area, then close first valve 6 and open third valve 10, pump clear water to pipeline 5 under the effect of pump 2, the clear water flows through flowmeter 9 on water pipe 8, the quality of clear water that gets into in pipeline 5 through flowmeter 9 measurement, close second valve 7 and third valve 8 in proper order after the quality of clear water that makes the pump send is unanimous with the dispersion of calculation, therefore, the mixed liquid remaining in the pipeline 5 completely enters the elevated tank 4, and the mixed liquid in the elevated tank 4 is then put into the synthesis kettle 3, so that the error of the mixed liquid entering the synthesis kettle 3 is reduced, and the quality stability of the synthesized product in the synthesis kettle 3 is improved.

When new mixed liquid is prepared again, in order to prevent the clean water remaining in the pipeline 5 from causing error influence on the new mixed liquid, in this embodiment, a water drain 11 is further disposed at a low position of the pipeline 5, a water valve 12 is disposed at the water drain 11, the water drain 11 and the water valve 12 are both disposed between the pump 2 and the second valve 7, and the water drain 11 and the water valve 12 are both at a low position relative to the second valve 7. When the mixed liquid in the elevated tank 4 completely enters the synthesis kettle 3, the water valve 12 is opened to release the clean water reserved in the pipeline 5 from the water drain 11, and the water valve 12 is closed after the release of the clean water is finished, so that the influence of the clean water reserved in the pipeline 5 on the mixed liquid can be reduced to the minimum when the new mixed liquid passes through the pipeline 5.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
