Background
In the production process of drying materials which are heat-sensitive, easy to decompose and easy to oxidize and need to recover solvents, a dryer is required to work in a vacuum state to heat and stir production raw materials, so that the production raw materials fully react and complete the drying process, and simultaneously, after the solvents are completely recovered, the vacuum is closed, the normal pressure state is recovered, so that the materials can be discharged, and the requirements of the next production process are met. In the process of drying the raw materials, the existing vacuum drying machine mainly adopts a vacuum rake type drying machine which takes saturated steam as a heat medium.
However, such dryers have a small heat transfer area and low throughput: because the rake shaft of the vacuum rake dryer is solid, the heating medium cannot be introduced into the interior of the rake shaft, and the heat transfer interface of the dryer is only the inner wall of the cylinder. The maximum filling amount of the materials in the inner volume of the dryer can only reach 70%, so the heat transfer area of the dryer is small, the drying time is long, and the yield is low.
SUMMERY OF THE UTILITY MODEL

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a double-blade vacuum rake dryer, which comprises a cylinder body, wherein a feed inlet is arranged at the top end of the cylinder body, a discharge outlet is arranged at the bottom of the cylinder body, two identical blade shafts are arranged in the cylinder body in parallel along the axis of the cylinder body, two ends of each blade shaft extend out of the cylinder body, two ends of each blade shaft are respectively provided with a sealing component, the sealing components are fixed on the cylinder body, and one end of each blade shaft, which is close to the feed inlet, is provided with a power device for driving the blade shafts to rotate; the paddle shaft comprises a main shaft, a plurality of paddle components are uniformly arranged on the outer wall of the main shaft at intervals, each paddle component comprises two identical fan-shaped paddles, and the two fan-shaped paddles are arranged on two sides of the main shaft in a staggered mode. The heat transfer effect of two identical blade shafts is increased to two times compared with that of a single blade shaft; the two fan-shaped blades included by each blade assembly are arranged in a staggered mode, so that the contact area of the materials during heating is increased.
Further, the outer wall of fan-shaped paddle is provided with rather than the vertically scraper blade, be equipped with in the fan-shaped paddle with the steam of main shaft intercommunication advances the pipe, fan-shaped paddle with the position department that the main shaft is connected is provided with the comdenstion water exit tube, the comdenstion water exit tube with the main shaft intercommunication. Heating media can be introduced into the main shaft and the fan-shaped blades, the heating media enter the fan-shaped blades through the steam inlet pipe after entering the main shaft, and condensed water in the fan-shaped blades is collected to the main shaft and is discharged from the condensed water outlet pipe. In the process, the materials are heated by the heat transferred by the fan-shaped blades and the cylinder body at the same time, are stirred under the rotation of the fan-shaped blades and the scrapers, and are finally discharged from the discharge port.
The utility model has the advantages that: the utility model provides a pair of double-blade vacuum rake dryer through setting up the double-blade axle, area of contact when increasing the material heating shortens drying time, and increase of production improves work efficiency, and it is little to have solved current vacuum rake dryer heat transfer area, problem that output is low.
