Description

The gum rosin production unit

Technical field

The utility model relates to technical field of chemical, relates in particular to a kind of equipment that is used to produce gum rosin.

Background technology

Rosin is as the internal sizing agent of the papermaking history of existing nearly two a century so far, because rosin belongs to renewable resources, so rosin still holds out broad prospects as sizing agent.Along with science and technology development, production technology, the performance of gum rosin all are greatly improved, develop into the free dispersion type rosin size of height of today from initial full saponification gum rosin, it no matter is consumption from glue, still from sizing efficiency, dispersion type rosin size will thoroughly replace the saponification gum rosin.The method of production dispersion type rosin size has multiple, the minimum methods of investment such as the most common, equipment are the normal pressure phase conversion methods, the principle of phase conversion method glue is that heating makes the rosin fusing under normal pressure, to reduce the intermolecular bonding force of rosin, reduce the alternate interfacial tension of rosin and water two by adding emulsifying agent (being tensio-active agent) again, form the w/o type emulsion, add phase inversion water at last under high-speed stirring, making phase reversal of emulsion is the O/W type.But the Measuring Precision of known equipment is low, and temperature fluctuation range is big, and product quality is difficult to be guaranteed, and that adds in the production process to be added materials is various in style, often causes the pause of production, is difficult to carry out serialization production.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of gum rosin production unit is provided, and this equipment not only can carry out serialization production, and has improved the quality of product.

For solving the problems of the technologies described above, the technical solution of the utility model is: the gum rosin production unit, comprise and be used to melt solid rosiny first reactor, be used for emulsifying agent is carried out pretreated the 3rd reactor, be used for the rosin after melting is mixed second reactor that generates gum rosin with pretreated emulsifying agent, be used to store the 4th reactor of gum rosin finished product, described first reactor, second reactor and the 3rd reactor are respectively equipped with fluid heater, between the corresponding reactor and the 3rd reactor with all be connected between the Raw material pail accordingly by pipeline, connecting pipeline between first reactor and second reactor is provided with first transferpump, connecting pipeline between the 3rd reactor and second reactor is provided with second transferpump, and the connecting pipeline between the 3rd reactor and the corresponding Raw material pail is provided with the 3rd transferpump; Be provided with first electronic scales between described second reactor and its support, be between described second reactor and the corresponding connecting pipeline and be flexible coupling; Be provided with second electronic scales between described the 3rd reactor and its support, be between described the 3rd reactor and the corresponding connecting pipeline and be flexible coupling; It also comprises the display unit that is used to show first electronic scales and the second electronic scales weighing data.

As a kind of improvement, first sequence controller that starts/close according to the corresponding transferpump of weighing Numerical Control of described these electronic scaless.

As further improvement, the junction of described each fluid heater and extraneous thermal source is equipped with flowrate control valve, described first reactor, second reactor and the 3rd reactor are respectively equipped with and are used to measure its temperature-detecting device of temperature of charge separately, control second sequence controller of corresponding flow control opening of valves size according to the detected temperature value of temperature-detecting device.

After having adopted technique scheme, the beneficial effects of the utility model are: since between the corresponding reactor and the 3rd reactor with all be connected between the Raw material pail accordingly by pipeline, the transfer of material is in sealed state in the production process thereby make, and can reach heat insulation effect on connecting pipeline by thermal insulation layer is set.Because the connecting pipeline between first reactor and second reactor is provided with first transferpump, connecting pipeline between the 3rd reactor and second reactor is provided with second transferpump, connecting pipeline between the 3rd reactor and the corresponding Raw material pail is provided with the 3rd transferpump, thereby material is shifted continuously, change traditional high potential difference method, reduced the space hold area of equipment.First and second electronic scaless can at high temperature carry out automatic accurate measurement to adding materials, operator control corresponding transferpump and start/close according to the display unit data presented, have improved product quality and production efficiency, have reduced working strength of workers.

Because it also comprises first sequence controller that starts/close according to the corresponding transferpump of weighing Numerical Control of described these electronic scaless, thereby has improved the level of automation of whole process of production.

Because the junction of described each fluid heater and extraneous thermal source is equipped with flowrate control valve, described first reactor, second reactor and the 3rd reactor are respectively equipped with and are used to measure its temperature-detecting device of temperature of charge separately, control second sequence controller of corresponding flow control opening of valves size according to the detected temperature value of temperature-detecting device, pass through flowrate control valve, the temperature-detecting device and second sequence controller can accurately be controlled the temperature of each reactor, further improve product quality and production efficiency, reduced working strength of workers.
