Abstract

The utility model discloses an energy-saving heating drum for drying, which comprises an external drum of which the inner wall is provided with material raising plates; an internal drum with end openings sealed is fixedly connected inside the external drum; a high-temperature drying cavity is formed between the internal drum and the external drum; retainer plates are arranged on the outer wall of the internal drum inside the drying cavity; the heat inside the heating drum is concentrated in the drying cavity to form a high-temperature environment; when material is dried, the material enters the drying cavity between the internal drum and the external drum; along with the rotation of the internal drum and the external drum, the material inside the drying cavity is raised by the material raising plates of the external drum, when the material reaches the top point, the material falls back to material holding grooves formed between the retainer plates on the outer wall of the internal drum due to the force of gravity; through the repeated raising and falling back, the retention time of the material inside the high-temperature zone of the drying cavity is prolonged and the drying efficiency is higher; as the drying process is performed inside the drying cavity, heat loss is prevented, production efficiency is improved and energy is saved by more than 20%.

Description

The energy saving baking heated roller

Technical field

The utility model relates to a kind of drying, drying plant, relates in particular to the oven dry heated roller that a kind of drying materials is used.

Background technology

In the prior art, material drying machine mainly is made of frame, hot-blast stove, loader, drier, air draft mechanism and driving mechanism etc., hot-blast stove is that the hot blast input is connected by warm-air pipe with an end of drier, the suction opeing of air draft mechanism is that air outlet is connected with the other end of drier, hot blast enters from input, through the inner chamber of drier, to discharge from air outlet, the charging aperture of drier and hot blast input are positioned at same end.Drier then mainly is made of a cylinder, is distributed with scraping wings on the inwall of cylinder.Cylinder rotates under the driving of driving mechanism, after material enters into cylinder from charging aperture, rotates with cylinder on the one hand and disperses, and on the other hand under the effect of scraping wings, is moved to the discharging opening direction by the charging aperture of cylinder, and moving direction is consistent with the hot blast direction.This drying mode is the following current oven dry, because the material and the hot blast of at this moment being dried are to move on same direction, physics principle according to thermal evaporation, under certain temperature condition, the speed of hot blast is fast more, the efficient of oven dry is high more, and still, wind speed is big more, the movement velocity of material is fast more, therefore the material in the cylinder is very fast is blown away by hot blast, thereby the material memory space in the cylinder is reduced, and the space availability ratio of drum cavity is low, a large amount of hot blasts can not fully contact with material, and wasted, increased production cost, reduced operating efficiency; And, because material movement speed is too fast, can not be fully dry.

The utility model content

Technical problem to be solved in the utility model provides a kind of energy saving baking heated roller that can make the abundant drying of material and the drying drum utilization rate is improved.

For solving the problems of the technologies described above, the technical solution of the utility model is: the energy saving baking heated roller, comprise outer cylinder, the inwall of described outer cylinder is provided with lifting blade, be fixedly connected with the interior cylinder of port closed in the described outer cylinder, form the hyperthermia drying chamber in described between cylinder and the described outer cylinder, the interior cylinder outer wall in the described drying cavity is provided with retainer plate.
