Embodiment Construction

[0035] The present invention will be further described below according to the accompanying drawings.

[0036] A novel drying process method for preparing superabsorbent resin, the specific drying process steps are as follows:

[0037] S1: Put heat transfer oil into the heat transfer oil pipe of the oil bath drying device, and set the temperature of the heat transfer oil to 100~170°C;

[0038] S2: Pour vegetable oil into the oil bath drying device, and set the temperature of the vegetable oil to 90~120°C;

[0039] S3: Put the prepared superabsorbent resin into the oil bath separation box, and put the oil bath separation box into the vegetable oil of the oil bath drying device;

[0040] S4: Turn on the stirring paddle of the oil bath drying device, and set the speed of the stirring paddle to 10~15r / min;

[0041] S5: After drying for 1 hour, take out the oil bath separation box;

[0042] S6: subjecting the superabsorbent resin in the oil bath separation box to a centrifugal de...

Abstract

The invention relates to the technical field of supper absorbent resin drying, in particular to a novel drying technical method for preparing supper absorbent resin. The novel drying technical methodfor preparing the supper absorbent resin specifically comprises the following drying technical steps: S1, filling a heat transferring oil pipe of an oil bath drying device with heat transferring oil,and setting the temperature of the heat transferring oil at 100-170DEG C; S2, pouring plant oil into the oil bath drying device, and setting the temperature of the plant oil at 90-120DEG C; S3, putting the prepared supper absorbent resin in an oil bath separating tank, and putting the oil bath separating tank in the plant oil of the oil bath drying device; S4, starting a mixing paddle of the oil bath drying device and setting the speed of the mixing paddle at 10-15r / min; S5, after carrying out drying for 1 hour, taking out the oil bath separating tank; S6, processing the supper absorbent resinin the oil bath separating tank by a centrifugal de-oiling technology; S7, processing the de-oiled supper absorbent resin by a washing technology; and S8, sieving the washed supper absorbent resin.

Description

technical field [0001] The invention relates to the technical field of superabsorbent resin drying, in particular to a novel drying process for preparing superabsorbent resin. Background technique [0002] Spherical water-absorbent resin is a kind of super-absorbent resin with excellent water-absorbing and water-retaining properties, and is mainly used in daily necessities, toys, medical care, and agriculture and forestry. Spherical water-absorbing resin is a polymerization production process. During the production process, there is more water and viscosity in the polymer, and the water needs to be dried to facilitate the use of various functions. The existing drying methods for spherical resins are static drying oven drying, boiling drying oven and belt drying method, but each has its own disadvantages. [0003] Static drying oven, the drying time is long, and the drying is uneven, and it takes a lot of manpower to turn it from time to time, which cannot guarantee the cons...
