Technical field
The present invention relates to a kind of indirect heating type drying device, relate in particular to a kind of rotating heat conducting sludge drying mechanism that is used to handle mud.
Background technology
The indirect heating type drying sludge is compared with direct gas flow formula drying sludge, has dry run safety, peculiar smell and is easy to advantages such as processing, thermal efficiency height, auxiliary equipment are few.At present, the indirect heating type drying sludge adopts the wedge shape paddle-dryer mostly, claim the hollow blade drying machine again, but the indirect heating type drying machine maximizes and to have following technical problem: 1, heat medium in blade, power transmission shaft, in the blade and in the shell flow velocity very low, heat transfer coefficient is not high.2, in order to make hot and cold medium separately, need usually power transmission shaft is cut open, the centre adds a dividing plate, and rigidity, the intensity of power transmission shaft reduce greatly.3, owing to the blade form complexity, blade pitch is bigger, and it is very big that the single device heat transfer area can not be done, so single device sludge-drying amount is little.
Summary of the invention
The invention provides a kind of heat transfer coefficient height, the fast rotating heat conducting sludge drying mechanism of rate of drying.
The present invention adopts following technical scheme:
A kind of rotating heat conducting sludge drying mechanism, comprise shell, power transmission shaft, be provided with charge door and exhaust outlet on the top of shell, bottom at shell is provided with discharge gate, power transmission shaft is located at the inside of shell, on power transmission shaft, be provided with the paddle sheet, power transmission shaft comprises interior pipe, outer tube, one end of outer tube is the heating agent import, the other end is heating agent outlet, and the outside of pipe in outer tube sleeve is located at is provided with second plug between the outer tube in outer tube heating agent exit and interior pipe, between interior pipe and outer tube, be provided with the thermal medium discharge pipe of paddle sheet, and on outer tube, be provided with through hole and be connected with the paddle sheet.
Compared with prior art, the present invention has the following advantages:
1, heat transfer coefficient height, the rate of drying between thermal medium of the present invention and mud is fast.Existing heat-conducting type drying machine Hollow Transmission Shafts diameter is bigger, the flowing velocity of thermal medium in axle is slower, the present invention is in order to make full use of the axle surface in larger axis footpath, power transmission shaft is designed to two concentric tube structures, reduced thermal medium actual internal area with the contacted wall of mud place, improve the flowing velocity of heating agent in axle, increased the heat transfer coefficient between heating agent and mud.
Simultaneously, owing to be provided with partition panel and deflector in the paddle sheet of the present invention, be provided with first deflector pressing close to cavity top place, and leave the gap between first deflector and the outer tube, be provided with second deflector pressing close to the outer tube place, leave the gap between second deflector and the collar, and first deflector and second deflector are spaced, the paddle sheet of this structure, organize the flow trace of thermal medium in the paddle sheet effectively, avoided the dead band, reduced aisle spare, make the flow velocity of thermal medium in paddle increase, improved the heat-transfer effect between heating agent and mud.
2, intensity height of the present invention.Because the present invention adopts two concentric transmission shaft structures, need not to cut open power transmission shaft and add dividing plate, rigidity, the intensity of power transmission shaft have been improved greatly, simultaneously, the paddle plate shape is simple, and blade pitch is little, compact conformation, the single device heat transfer area can be done greatly, therefore can improve the dry disposal ability of single device.
3, external jacket heat-transfer effect of the present invention is good.The present invention is provided with external jacket in the outside of rotating heat conducting sludge drying mechanism, also be provided with deflector in the external jacket, improved the flow velocity of thermal medium in chuck, strengthened the heat-transfer effect of chuck, deflector well is connected shell with the drying machine inwall simultaneously, has improved the withstand voltage properties of chuck.
