Abstract

The utility model provides a self-cleaning rotary cylinder drying machine, comprising a barrel and the rotating device. A flight is equipped on the inner wall side of the barrel. The Contacted bottom of the flight and the barrel wall, and the flight top are both of a circular arc shape. The flight top is provided with a soft tension element. The utility model fully cleans the materials adhered on the barrel wall and the flight by adopting the arc flight with the tension element. The utility model avoids the fire phenomenon caused by long-term adhesive materials on the device, and is safe in use. The materials are fully agitated; the contact area with hot blast is enlarged; the heat changing efficiency is improved, and the drying effect is favorable.

Description

The self-cleaning revolving drum drier

(1) technical field

The utility model relates to revolving drum drier, belongs to the drying machine technical field.

(2) background technology

Revolving drum drier is a big class of traditional drying equipment, is widely used in fields such as mine, metallurgy, chemical industry, building materials.The version of the revolving drum drier that present domestic employing is more is to be provided with the flight raising material unit on the internal face of revolving drum, when revolving drum rotates under its tumbler drives, the flight device of its wall also rotates with revolving drum, and the material to be dried in the drying machine is lifted.Along with the further rotation of revolving drum, material to be dried drops down onto the bottom of revolving drum under disengaging flight device is thrown under the gravity effect of self.Afterwards, along with the rotation of revolving drum, be picked up once more, promote, throw down, in dropping process repeatedly, material to be dried directly contacts with the hot blast that enters drying machine, carries out the caloic exchange, reaches the purpose that dehydrates.The revolving drum drier of this structure is at the granular bulk material of xeraphium, and when requiring dried product and initial material difference is little on granularity, obvious drying effect.But during the material (as Choline Chloride) that this drying machine is big in dry viscosity and moisture is bigger, there is following shortcoming in the drying machine of this kind structure: because material at high temperature is bonded on the barrel of revolving drum easily, overlong time, material catches fire easily, causes the consequence of danger close.For avoiding catching fire, often the hot blast temperature with system reduces, and causes the waste of the equipment and the energy like this, and production cost is improved.

(3) summary of the invention

The utility model is at the deficiency that prior art exists, provide a kind of when handling the organic materials of viscosity is big, moisture is bigger particle or powdery safety and the self-cleaning revolving drum drier of better drying effect is arranged.

The utility model adopts following solution:

The self-cleaning revolving drum drier is made up of cylindrical shell and tumbler thereof, and the cylinder inboard wall face is provided with flight, and bottom that flight contacts with barrel and flight top are circular-arc, and the flight top is provided with soft flexible element.

Flexible element adopts reinforced standard hoisting chain.

The length of flexible element is two space arc length between the flight.

The utility model is removed the material that is bonded on barrel and the flight get off by adopting the arc flight of band flexible element fully, has avoided material long-term bonding and the phenomenon of catching fire is safe in utilization on equipment; And material is stirred fully, and the contact area increasing with hot blast has improved the efficient of heat exchange, and drying effect is good.

(5) specific embodiment

Fig. 1 has provided structural representation of the present utility model.The same the utility model with existing revolving drum drier is made up of cylindrical shell 2 and tumbler thereof, and tumbler is made up of buncher 1 and transmission mechanism, also is provided with flight on cylindrical shell 2 internal faces.Difference be flights (referring to Fig. 3, Fig. 4) everywhere such as side plate 3, header board 5 and back plate 6 adopted the rounding off form and in the flight welded top reinforced standard hoisting chain 4 (referring to Fig. 2, Fig. 4).Each flight is according to existing flight arrangement mode in the arrangement of inner barrel, and arc form is all adopted to the top of flight in the bottom that each flight contacts with cylinder inboard wall 7, and the mode with cylindrical shell 2 rounding ofves is adopted in the bottom.So just guaranteed that material is taken up at flight, in the elevate a turnable ladder, the process that falls, on flight, do not had the angle of buildup, allowed material can be reinforced type standard hoisting chain 4 and clean out at an easy rate.

The thickness degree of reinforced standard hoisting chain 4 is according to decisions such as the situation of material and output, its length is that two space curves between the flight are long, and promptly reinforced standard hoisting chain 4 will be cleared up back plate 6, the barrel 7 between two flights and the header board 5 of self flight of front flight.Reinforced standard hoisting chain 4 is welded on the top of the header board 5 of flight, on a flight, have the reinforced standard hoisting chain 4 of three to six rows, gyration along with cylindrical shell 2, flight is in the process of elevate a turnable ladder, reinforced standard hoisting chain 4 was scraped the bottom of barrel 7 and flight under the effect of gravity, allow the material that is bonded on cylindrical shell and the flight drop under the effect of reinforced standard hoisting chain 4, participated in the caloic exchange.

In whole cylindrical shell, the flight of band chain bar 4 only accounts for half of cylindrical shell, and in the part of back, the moisture of material reduces, and viscosity descends, and can adopt the arc flight of band chain bar 4 not or adopt common flight.

Claims
