Abstract
The utility model discloses a dosing device for pilot-scale experiments of modified starch projects. A dosing pipe in a reaction tank of the device is provided with a plurality of medicine outlets; and nozzles are arranged at the medicine outlets. The device also comprises a plurality of dosing tanks and a main pipeline connected with the dosing pipe in the reaction tank, wherein the main pipeline is connected with a plurality of branch pipelines; and several branch pipelines are connected with different dosing tanks, and the rest branch pipelines are connected with a washing water tank and a compressed air tank. The dosing device has the advantages that each medicine outlet is provided with a nozzle, so a medicine can be added in an atomization form, and the problems of nonuniform medicine addition and violate local reaction; and because the main pipeline and the branch pipelines are separately arranged and a pipeline switching purification facility for pneumatic conveying and drying and clear water washing for the main pipeline is equipped, the space occupied by the pipelines is reduced, the operation is convenient and the research and development cost is reduced.
Description
Technical field
The utility model relates to a kind of modified starch project pilot scale chemicals dosing plant.
Background technology
At present in the pilot scale proof procedure of modified starch prescription; The interpolation of chemical agent all is to adopt the mode of single pipeline single-point dosing to carry out usually; This dosing method exists following deficiency: the one, and devices needed, facility are more, also need take a large amount of spaces.The 2nd, medicine and milk of starch local reaction are violent, and W-response is inhomogeneous, have strengthened the control difficulty of reaction process.The 3rd, the local too fast interpolation of some medicine can cause the local gelatinization of starch, has influence on subsequent reactions and quality product.Because above-mentioned deficiency usually causes production operation inconvenient, the pilot experiment data that draw are inaccurate, can't instruct enlarging to produce, and can't form production formula, also increased R&D costs simultaneously.
Summary of the invention
The goal of the invention of the utility model is to provide a kind of modified starch project pilot scale chemicals dosing plant, adopts this device administration to improve the quality of products, and steady operation conditions can also reduce production costs.
The technical scheme of the utility model is: this chemicals dosing plant comprises retort, is provided with a plurality of medicine outlets on the delivery tube in retort, on each medicine outlet, all installs a nozzle additional.
This device can also comprise a plurality of grug feeding jars with one with retort in the Trunk Line that is connected of delivery tube; On Trunk Line, connect many lines; By-pass valve control all is housed on every lines; Several lines wherein connect with different grug feeding jar respectively, and all the other lines are connected with compressed air tank with the wash water jar respectively, on every and the tank connected lines of dosing, volume pump are housed all.On the lines of wash water jar water pump is housed, air compressor machine is housed on the compressed air tank.
Effective result of the utility model is: owing on each medicine outlet, all installed nozzle additional, thus medicine can be inserted with the form of atomizing, solve medicine and added inequality, the problem that local reaction is violent makes entire reaction more even, and product is more stable.Because Trunk Line and lines set up separately, and the establishing wind that has been equipped with Trunk Line send dry up, the pipeline switching purification facility of water purification flushing, reduced the pipeline occupation space, made things convenient for operation, reduced R&D costs.Make the product property of pilot scale more stable, it is more reliable to fill a prescription, and then reliable formulation guide is provided for industrialized production.

Embodiment
Example 1
As shown in Figure 1, this chemicals dosing plant comprises retort 1, is provided with a plurality of medicine outlets 3 on the delivery tube 2 in retort 1, on each medicine outlet 3, all installs a nozzle 4 additional.
This device also comprise a plurality of grug feeding jars 5 with one with retort 1 in the Trunk Line 6 that is connected of delivery tube 2; On Trunk Line 6, connect many lines 7; By-pass valve control 8 all is housed on every lines 7; Several lines 7 wherein connect with different grug feeding jar 5 respectively, and all the other lines 7 are connected with compressed air tank 10 with wash water jar 9 respectively, on every and the tank connected lines 7 of dosing, volume pump 11 are housed all.On the lines 7 of wash water jar 9 water pump 12 is housed, air compressor machine 13 is housed on the compressed air tank 10.
Example 2
To produce hydroxypropyl level starch is example, and the grug feeding jar 5 among the figure is respectively dissimilar chemical jars.Setting 1 is the acetic anhydride jar, and 2 is the propylene oxide jar, and 3 is hydrochloric acid tank.Open the volume pump power switch, control through regulating 11 pairs of medicine interpolations of volume pump speed,
Step is following:
1, the milk of starch in the retort 1 is transferred to concentration, temperature, the pH value that reaction requires.
2, open the by-pass valve control 8 of the grug feeding jar 5 that propylene oxide is housed, start volume pump 11, propylene oxide is carried out multiple spot add, the by-pass valve control 8 of other grug feeding jar 5 state that keeps shut.
3, treat that the propylene oxide interpolation finishes, and closes the by-pass valve control 8 of the grug feeding jar 5 that propylene oxide is housed; Open air compressor machine 13, open the by-pass valve control 8 of compressed air tank 10, the residual propylene oxide in the Trunk Line 6 is blown into retort 1, close the by-pass valve control 8 of air compressor machine and compressed air tank 10; Open the by-pass valve control 8 of wash water jar 9, start water pump 12, flushing line.
4, reaction finishes, and opens the by-pass valve control 8 of the grug feeding jar 5 that hydrochloric acid is housed, and starts volume pump 11, and milk of starch is neutralized, reach the requirement pH value after, close the by-pass valve control 8 and volume pump 11 of the grug feeding jar 5 that hydrochloric acid is housed; Open air compressor machine 13, open the by-pass valve control 8 of compressed air tank 10, the residual hydrochloric acid in the Trunk Line 6 is blown into retort 1, close the by-pass valve control 8 of air compressor machine 13 and compressed air tank 10; Start water pump 12, open the by-pass valve control 8 of wash water jar 9, flushing line.
5, the milk of starch after the neutralization gets product through dehydration, washing, drying, pulverizing.
