Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
This example provides a method for preparing a powdered detergent, comprising the steps of:
s1 is used for configuring slurry;
s2 is a step of spray-drying the slurry;
s3 is used for the step of separating and packaging the finished powder detergent.
Further, the step S1 of configuring slurry includes:
s11, adding quantitative sodium alkyl benzene sulfonate and water into a batching tank, and heating to 40-50 ℃;
s12, adding CMC and the fluorescent brightener in sequence, and heating to 50-55 ℃;
s13, adding sodium tripolyphosphate, and controlling the temperature to be 60-65 ℃;
s14, adding potassium carbonate and sodium toluene sulfonate;
s14 adding sodium silicate and Natrii sulfas after the mixed solution is dissolved.
It will be appreciated by those skilled in the art that sodium silicate is beneficial in improving the structure of the slurry and in providing a uniform, free flowing, non-caking finished product. Sodium tripolyphosphate and sodium takotate can absorb water to generate hydrate containing crystals, so that the water content in the finished product is increased on the premise of keeping the free fluidity of the product. The sodium toluene sulfonate or sodium xylene sulfonate is favorable for adjusting the slurry year and increasing the fluidity. Mirabilite and sodium carbonate can improve the apparent density of the product. After all the components are put into the slurry, the total content of solid components in the slurry is generally 60 to 65 percent, and the viscosity is kept to be about 0.5Pa.s (70 ℃). The concentration of the slurry has the greatest influence on the subsequent drying and forming, the thin slurry has much water, excessive heat consumption during drying, and the dried product has small particles, thin particle walls and is crushed into powder. The viscosity of the slurry is proper, and the excessive viscosity affects atomization, so that the drying and forming of the product are affected. The temperature of the slurry can not be too high, if the temperature exceeds 100 ℃, the obtained finished product is easy to change into powder, and the temperature can not exceed 70 ℃. In addition, after the slurry is prepared, the slurry needs to be filtered and degassed, so that the slurry structure is compact, and the apparent density of the product is improved. The degassed slurry should be fed into an aging tank for a moment (30-40min) to allow sodium tripolyphosphate to form hydrate containing crystal water, so as to improve fluidity and pressure resistance of the dried powder.
Further, the step S2 of spray-drying the slurry includes:
s21, spraying the slurry into the tower in a mist form through a nozzle under the pressure of 5.9-11.8Mpa by using a high-pressure pump;
the slurry of S22 meets hot air of high temperature to exchange heat.
As will be appreciated by those skilled in the art, atomization of the slurry is a key link in achieving high tower spray drying efficiency. The state of the atomized droplets of the slurry depends on the original shape of the slurry. The pressure of the high-pressure pump, the position and number of the spray guns, the form, structure and size of the spray nozzles all influence the atomization. The spray tower should be of sufficient height to ensure that the droplets have sufficient time to dry sufficiently during descent and become hollow granules.
Further, the step S3 of separately packaging the finished powdered detergent includes:
s31 dropping the dried product particles to the conical bottom of the drying tower;
s32, conveying the dried finished product particles by using a wind conveying device;
s33, sending the dried finished product particles into a cyclone separator for separation and recovery;
s34, sending the dried finished product particles into a wet scrubber for treatment, thereby achieving the emission standard;
s35, emptying the dried finished particles.
Further, the preparation method of the powdery detergent provided by the embodiment further comprises an auxiliary agent adding step, and specifically comprises the following steps: for the addition of perfume, bleaching agent, softening agent and enzyme preparation.
It will be appreciated by those skilled in the art that the above auxiliaries need to be added after the cold separation of the washing powder or be incorporated by means of a specific after-dosing unit.
Further, the enzyme preparation is prepared by a granular enzyme mixing method or an enzyme direct adhesion method.
It will be appreciated by those skilled in the art that some bleaching agents such as perborates, percarbonates etc. can only be added to the finished laundry powder product by mechanical mixing after dusting.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
