A steam pipe rotary dryer belongs to a dividing wall heat transfer drying device and is formed by additionally arranging a steam heat exchange pipe on the basis of a traditional direct heat transfer rotary dryer. The wet material enters from one end of the device under a certain inclination of the cylinder body along with the rotation of the rotary cylinder, and is discharged from the other end of the device under the heating of the tube nest. At present, the dryer is widely applied to industries such as feed, grease, fertilizer, coal slime and the like.

The material dried by the steam pipe rotary dryer is provided with a material level control device at the discharge end and is uniformly arranged on the circumferential side of the cylinder. The material level controller is inserted into a gap in the heating pipe bundle, the dried material moves to the position of the discharge port, and is discharged from the opening of the material level controller after being stacked to the height of the material level control port. The material level controller effectively keeps the whole filling material level of the dryer, fully exerts the efficiency of the heating pipe, improves the drying capacity of the dryer and is an important component on the steam pipe rotary dryer. However, the discharging apertures and the arrangement number of the material level controllers are influenced by the arrangement density and the type of the heating tube bundles in the dryer, so that the phenomenon of unsmooth material arrangement can occur, and therefore, the ideal pipe arrangement effect can not be achieved when the design is considered.

With the wide use of large steam pipe rotary dryers, the types of materials to be dried are more and more, and therefore strict requirements are placed on the design types of the discharge ports. The material level outlet needs to be redesigned to achieve the purpose by controlling the material level of the dryer and freely arranging the heating tube bundles according to materials with different specifications to ensure the quality and capacity requirements of the dried product.

Preferably, the shape of the end socket is circular arc.

Preferably, the diameter of the end socket is smaller than the maximum pipe distribution diameter of the innermost heating pipe of the steam pipe rotary dryer.

Preferably, the end socket is located in the area formed by the innermost heating tube.

Preferably, the number of the discharge pipes is 8, and one ends of the discharge pipes are uniformly distributed on the end sockets.

Preferably, the steam collecting chamber is oval-sphere-shaped.

Preferably, the discharge holes are uniformly distributed on the outer wall of the steam collecting chamber.

Preferably, the discharging direction of the discharging port is vertical to the horizontal line.

Preferably, the center of the end enclosure is positioned on the central axis of the cross section of the cylinder body of the steam pipe rotary dryer.

The utility model has the advantages that:

(1) the discharge gate of steam pipe rotary dryer is located barrel circumference side, the utility model discloses the position of adjustment discharge gate sets up it on the collection steam chamber, sets up the head on the collection steam chamber, and the ejection of compact direction is equal to the axial ejection of compact. The material is moved and is piled up in head department under the desiccator drives, gets into the discharging pipe from the head, flows from the discharge gate, and the effect of control material level has both been played in the ejection of compact of head department, has avoided touching of discharge gate department and heating pipe again, and the discharging pipe receives the distance restriction scheduling problem between the heating pipe.

(2) The utility model discloses a discharging device is applicable to the drying material of different graininess, can freely adjust ejection of compact bore and quantity, is difficult to be blockked up by the material. The setting of the material level controller is not influenced by the arrangement of the heating tube bundles of the dryer, so that the drying efficiency of the dryer is greatly improved, the production capacity of the dryer is improved, the parts of the equipment are simplified, the manufacturing cost of the equipment is reduced, and the service life of the equipment is prolonged.
