Specific embodiment

The utility model is furtherd elucidate with reference to specific attached drawing, present embodiment is with the utility model technology Implemented under premised on scheme, it should be understood that these modes are merely to illustrate the utility model rather than limitation the utility model Range.

As shown in Figures 1 to 4, the utility model embodiment provides a kind of drum type drying apparatus, which includes two Bearing 1 opens up mounting groove on two bearings 1 respectively, and multiple carrying rollers 2 are separately installed in mounting groove, and the upside of bearing is equipped with roller 3, the outside of roller 3 is set there are two rolling ring 4, and rolling ring 4 can be integrally formed with roller 3, also can after separately manufacturing by welding or Other modes are fixed on the outside of roller 3, and two rolling rings 4 are separately positioned on 2 upside of carrying roller of two bearings 1 so that carrying roller 2 and rolling Cylinder 3 rolls connection.3 outside of roller is equipped at least one gear ring 5, and gear ring 5 is preferably provided at the outside of rolling ring 4, can also set It puts between two bearings 1.Gear ring 5 is more demanding to material, therefore is preferably then arranged fixation with 3 separately manufacturing of roller In the outside of roller 3.Gear ring 5 is connect with the output gear 7 of gear-box 6, and output gear 7 is fixed on the output shaft 8 of gear-box 6 On.Gear-box 6 is connect with driving motor 9, and driving motor 9 is connect with control unit, and driving motor 9 is used for 6 turns of sliding tooth roller box Dynamic, control unit is used to control the rotating speed of driving motor 9, and then roller 3 is made to be rolled on carrying roller 2.3 outside of roller is equipped with outer cover 10, the upside of outer cover 10 is equipped with heating unit 12, and multiple tracks parietal suture 11 is opened up on roller 3, and the size of parietal suture 11 is less than the ruler of material It is very little.The inside of roller is equipped with and broadcasts plate 13, broadcasts plate 13 and is spirally being distributed in roller 3.Material can be made in roller 3 by broadcasting plate 13 It inside stirs, and generates axial movement.

As shown in figure 5, the carrying roller 2 of the utility model embodiment includes support roller sleeve 21, pacify respectively on the inside of 21 both ends of support roller sleeve It fills there are one bearing 22,22 inside of bearing to be equipped with roller carrier shaft 23, and roller carrier shaft 23 is mounted on bearing 1, and the outside of bearing 22 is set There is gland 24, gland 24 is bolted with support roller sleeve 21, and bearing 22 is fixed in support roller sleeve by gland 24.

As shown in figure 5, the support roller sleeve 21 of the utility model embodiment is in " T " type shapes, the rolling face on the outside of support roller sleeve includes the One rolling face 211, the second rolling face 212 and the third rolling face 213 being arranged between the 211 and second rolling face 212 of the first rolling face, the Three rolling faces 213 are arc surface, and rolling ring 4 opens up globoidal structure 41 with third rolling 213 corresponding position of face, and globoidal structure 41 is rolled with third 213 radian of face is identical.Carrying roller 2 on two bearings 1 is oppositely arranged so that the third rolling face 213 of two groups of carrying rollers 2 can be by roller 3 position restriction.Third rolls face 213 with globoidal structure 41 in cooperation, and the resistance and reduction that can reduce the rotation of roller 3 rub Rubbing noise.

As shown in fig. 6, also support roller sleeve 21 can be arranged to " I " shapes, the structure on the right side of " I " shape support roller sleeve 21 with " T " type support The structure in roller set left side is identical, i.e., including two cambered surfaces, globoidal structure is opened up in the both sides of rolling ring 4." I " shapes support roller sleeve 21 limits Position is better.Other existing limiting devices can also be used to limit roller 3.

Roller 3 can generate axial float in rotation process, make the lateral forces that it is generated on rod is turned, to make bearing 22 can run well under the action of the lateral force, and the bearing 22 of the utility model embodiment preferably uses taper roller axis It holds.As shown in figure 5,22 inside of bearing is additionally provided with oil sealing 25.

Material overturns in heating process in roller and is stuck in parietal suture 11 in order to prevent, as shown in fig. 6, it is preferred that parietal suture is set It is set to horn-like.Its upside is the inside of roller 3, and downside is the outside of roller 3, i.e. the width at 11 any point of parietal suture is equal Less than the width of any position on the outside of it.

In order to make increase drying effect, as shown in Fig. 2 or 6, multiple wind deflectors 14, wind-guiding are additionally provided in the outside of roller 3 Plate 14 is arranged on parietal suture 11 and meets side to direction of rotation.Wind deflector 14 generates the air-flow of rotation in 3 rotation process of roller, So as to make the temperature around roller 3 uniform, the heat that heating unit 12 generates can also be introduced into roller 3 by wind deflector 14 It is interior, and then the temperature in roller 3 is increased, the material of rolling coordinates, and then substantially shorten drying time with the air-flow of rotation.

In order to increase drying effect, as shown in fig. 7, the center line direction inclination that 14 preferred outer end of wind deflector is close to parietal suture is set It puts so that the high-temperature gas in 3 outside of roller is increased by the flow of parietal suture.

Preferably using steam pipe coil, other heating units can also be used in the heating unit 12 of the utility model embodiment.It adopts It can prevent material from fire occurring in drying course with steam pipe coil.Steam pipe coil can also be connect with motor-driven valve, in outer cover Side is also equipped with temperature sensor, and motor-driven valve is connect with temperature sensor with control unit.Control unit can set drying Temperature, and pass through the signal for receiving temperature sensor, to control the aperture of motor-driven valve.When temperature is less than setting value, control electricity The aperture of dynamic valve increases, make by quantity of steam increase, and then increase the temperature of drying.When temperature is higher than setting value, control The aperture of motor-driven valve reduces, make by quantity of steam reduce, and then reduce drying temperature, operated so as to fulfill constant temperature drying.

The utility model can be used cooperatively with conveyer belt or other feeding devices, as shown in Figure 1, material is defeated from left side It send to the inside drying of the utility model embodiment, in drying course, material is overturn in the lower inside of roller 3, and with broadcasting plate 13 to gradually moving right, and is gradually discharged from the right side of roller 3.Drying time can be adjusted by regulation motor rotating speed.

In conclusion the utility model by set it is spiral helicine broadcast plate, material is made to be overturn in drying course, and pass through Parietal suture coordinates with wind deflector, increases the mobility of air in roller, and then drying efficiency is high.Material broadcasts the work of plate in helical form It is made gradually to be discharged in drying course under, convenient to be used cooperatively with production line without other discharge devices, excellent.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, under the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
