Abstract
The utility model discloses a combined drying system for gel materials, and belongs to the technical field of manufacture for high-polymer materials. The combined drying system comprises a gel material conveyor belt. A microwave dryer and a hot-air dryer are sequentially arranged on the conveyor belt, and temperature and humidity sensors are arranged on the conveyor belt and are positioned between the microwave dryer and the hot-air dryer. The combined drying system has the advantages that wet gel with the water content of about 45% is quickly dehydrated and dried by the microwave dryer at first, the water content of the gel is quickly reduced and is about 10%, at the moment, particles of the gel are rarely adhered with one another, the flowability of the gel is good, and then the gel can be dried by the hot-air dryer at a follow-up stage, so that an integral drying procedure can be completed, and the combined drying system is high in processing speed and good in drying effect.
Description
Technical field
The utility model relates to a kind of gel material composite drying system, belongs to the preparing technical field of macromolecular material.
Background technology
Because superabsorbent gels moisture after polymerisation is higher, generally, in 45% left and right, material fluidity is poor, and between particle, degree of adhesion is large, and porosity is low, and thermal conductivity factor is poor, therefore in process of production, all needs to use heater to carry out drying to gel.In industry, generally adopt the heated-air drying method to be heated at present, but heating effect is inhomogeneous, heat is difficult to be delivered to gel inside, and extremely difficult dry, heat utilization efficiency is low.
Summary of the invention
For addressing the above problem, the utility model provides a kind of working (machining) efficiency fast, the gel material composite drying system that drying effect is good.
The utility model is that the technical scheme that its problem of solution adopts is:
Gel material composite drying system, comprise conveyer belt, on conveyer belt, from feedstock direction, is disposed with microwave dryer and hot-air drier, is provided with the humiture inductor on conveyer belt between microwave dryer and hot-air drier.
Preferably, described conveyer belt is provided with the material scraper plate.
The beneficial effects of the utility model are: adopt microwave dryer can be in a short period of time moisture in gel to be down to 10% left and right from 45%, greatly shortened drying time.Although it is fast that microwave dryer has rate of drying, high yield saves time, easy to operate, the characteristics such as occupation area of equipment is few, but want the moisture in the finish-drying gel rubber material, can cause destruction in various degree to gel structure, so to the low moisture gel, the gel that for example moisture content is less than 10%, should not adopt the method for microwave drying.Therefore, the mode that the utility model has adopted microwave dryer to combine with hot-air drier, at first adopt microwave dryer to carry out quick dewatering drying the wet gel of moisture 45% left and right, rapidly gel moisture is down to 10% left and right, at this moment between gel particle, adhesion is few, and material fluidity is good, now can adopt hot-air drier to carry out follow-up drying, and then completing whole dry run, fast, drying effect is good in processing.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Gel material composite drying system as shown in Figure 1, comprise the conveyer belt 1 for transporting the gel material, be disposed with microwave dryer 2 and hot-air drier 3 from feedstock direction on conveyer belt 1, be provided with humiture inductor 4 on conveyer belt 1 between microwave dryer 2 and hot-air drier 3, humiture by 4 inductions of humiture inductor from the gel rubber material of microwave dryer 2 outputs, humiture inductor 4 is sent to control system by information again, and control system can change according to the information intelligent detected the heating mode of hot-air drier 3.Further, described conveyer belt 1 is provided with material scraper plate 5, and material scraper plate 5 can the free adjustment height, higher than the material of material scraper plate 5, is scraped backward, prevents that material stacks is too thick.
Operation principle of the present utility model is, adopts microwave dryer 2 can be in a short period of time moisture in gel to be down to 10% left and right from 45%, greatly shortened drying time.Although it is fast that microwave dryer has rate of drying, high yield saves time, easy to operate, the characteristics such as occupation area of equipment is few, but want finish-drying moisture wherein, can form destruction in various degree to gel structure, so to the low moisture gel, the gel that for example moisture content is less than 10%, should not adopt the method for microwave drying.Therefore, the method that the utility model has adopted microwave dryer 2 to combine with hot-air drier 3, at first adopt microwave dryer 2 to carry out quick dewatering drying the wet gel of moisture 45% left and right, rapidly gel moisture is down to 10% left and right, at this moment between gel particle, adhesion is few, material fluidity is good, now can adopt with hot-air drier 3 and carry out follow-up drying, and then complete whole dry run.
Above specification is described, is only principle of the present utility model and embodiment, everyly according to essence of the present utility model, carries out any simple modification and variation, within all belonging to the desired protection domain of the utility model.
