Description

Rotary disc type heating dryer

The utility model is a kind of rotating disc type heat drying machine, belongs to the drying equipment technical field.

At present, in dye chemical industry and food-processing industry production, adopting roller drier in a large number.This drying machine has thermal efficiency height, and material heated time in dry run is short and favourable to heat sensitive material, and the product drying degree is easy to advantages such as control.But the heating surface of roller drier is the cylindrical surface of its rotatingcylindrical drum, and the size of heating surface depends primarily on diameter.Be to enlarge heating surface, just essential dilated diameter causes cylinder too huge and waste steel, cost surge in a large number.Therefore, the maximization of roller drier is subjected to certain limitation, and Chang Buneng satisfies the requirement of output.Produce needs for satisfying, often have to adopt the operation in parallel of many roller driers.

The purpose of this utility model is to overcome the above-mentioned shortcoming of conventional rollers formula drying machine and keeps its advantage, increases the heat drying area that its unit volume has, thereby realizes the maximization of drying machine and reduce cost.

Design of the present utility model is the substantially dry method that keeps cylindrical drier, but done improvement in essence textural, with original only change into mainly utilizing as the heat drying face with cylinder surface a plurality ofly be loaded on hollow rotating disk in the rotating shaft as the heat drying face, and taked to improve therewith mutually suitable structural measure, guaranteed the goal of the invention realization. For simplicity, be illustrated as an example with a kind of structural shape below.

To of the present utility model a kind of structural shape shown in Figure 6, the operation principle and the technical characterictic of rotating disc type heat drying machine can be described by Fig. 1.

Rotating disc type heat drying facility have motor that steam inlet a that upper shell 31, bleeding point 32, lower house 33, dry powder outlet 34, hollow shaft sleeve 5 and internal axle sleeve 4 form and condensation-water drain b, driving and supporting hollow shaft sleeve rotate, variable-speed motor, block bearing etc.The effect of these parts and structure and traditional roller drier are similar substantially.Technical characterictic of the present utility model is:

1, replace a cylinder as the slurry heating surface with a plurality of hollow rotating disks 18.Hollow rotating disk can be welded by symmetrical conical plate 2, normal direction ribbed 1, the reinforcement cylinder 15 that is equally spaced, outer toroid 16 and dish drum 20.The smooth outer surface of hollow rotating disk is smooth.Have logical steam hole and row's condensation water hole (see figure 6) in the middle of the dish drum.Heating steam enters hollow rotating disk 18 by steam inlet a through hollow shaft sleeve 5 and eyelet 37, thus the lip-deep slurry of heating plate, and condensed water is then discharged by eyelet 37, internal axle sleeve 4 and condensation-water drain b.

Hollow rotating disk 18 arranges equidistantly that along hollow shaft sleeve 5 its installation method is seen Fig. 6.Dish drum 20 usefulness keys are contained on the hollow shaft sleeve 5, and the rotation of hollow shaft sleeve is delivered to hollow rotating disk.Be lined with sealing gasket 36 between the two dish drums, the outermost end both sides with about revolve big nut and tighten, assurance steam can not leak.All have eyelet 37 on dish drum and the hollow shaft sleeve, eyelet communicates with steam inlet a and condensation-water drain b.

2, have and the corresponding pectination slurry vessel 7 of hollow rotating disk, its profile such as pectination contract are gone between the hollow rotating disk.When hollow dial rotation, the slip in the pectination slurry vessel is coated on the hollow rotating disk equably.In the contact position of the teeth groove of pectination slurry vessel and the conical plate of hollow rotating disk, heat-resisting silicone rubber plate 9 is housed, silicone rubber plate 9 is fixing with elasticity Ω clevis 8, and is lined with polyester flake 17 so that mounting or dismounting.The soft rubber plate 6 that exceeds silicone rubber plate 9 is equipped with in the front and back end of pectination slurry vessel, can prevent that slip from overflowing from the front and back end.When hollow dial rotation, the out-of-flatness of conical plate and the axially distortion that causes of vibration can be leaned on silicone rubber plate 9 to compensate, thereby be guaranteed that slip does not leak, and can be coated on equably on the hollow disc surfaces that has been heated by steam.

3, have with the corresponding elastic scraper assembly of hollow rotating disk 19(see Fig. 1,4,6), its shape is also gone between the hollow rotating disk as the pectination contract.The elastic scraper assembly has T shape knife rest 11, knife rest axle sleeve 3 bearing support that is welded, and bearing support one end is enclosed within on the hollow shaft sleeve 5 by knife rest axle sleeve 3, also is lined with fluoroplastics lining 21 between knife rest axle sleeve and hollow shaft sleeve.The other end is fixed on the supporting base 35 on the lower house 33.When hollow dial rotation, be fixed in the elastic scraper 12 that the multilayer stainless steel thin slice on the T shape knife rest 11 constitutes with pressing plate 10 and screw, the siccative on the hollow disc surfaces can be scraped.Elastic scraper assembly 19 can be made small axial float between hollow rotating disk, with machining deviation and the axial float that compensates hollow rotating disk.

The configuration of pectination slurry vessel and elastic scraper assembly makes hollow rotating disk turn over 330 ° approximately after the pectination slurry vessel is reinforced, and siccative is scraped by elastic scraper.The rotating speed of hollow rotating disk then can be regulated by variable-speed motor.

From top explanation as can be known, heating and drying method and cylindrical drier that the utility model adopted are basic identical, but owing to adopted many hollow rotating disks as heating surface, make heating surface (area) (HS increase by 4～5 times, thereby can realize the maximization of heat drying equipment, tangible economic benefit is received in minimizing equipment, factory building investment.The utility model can replace the slip drying operation that traditional cylindrical drier is used for various industrial processes.In addition, utilize the characteristics that the utlity model has very big heating and scraper area, also can under normal pressure or reduced pressure, use as maximization thin film evaporation inspissator.At this moment, the elastic scraper material changes heat resistant plastice into by stainless steel.
