Example Embodiment

[0036] Example 1

[0037] Such as figure 1 , This embodiment provides a dryer, including

[0038] The furnace body 1 is arranged in a horizontal direction, and has a cavity, a feed port 11 and a discharge port 12 for feeding and taking out materials;

[0039] The rotating shaft 2 passes through the cavity of the furnace body 1;

[0040] The stirring assembly is arranged on the rotating shaft 2 and is used to stir and crush materials in both the axial and radial directions of the rotating shaft 2; and

[0041] The heating device is used to heat the wall surface of the furnace body 1 and / or the rotating shaft 2; or to introduce external hot gas into the furnace body 1 to exchange heat with the material.

[0042] In the above-mentioned dryer, in the process of drying the materials, the materials are added into the cavity of the furnace body 1, and the high-temperature air flow is added into the cavity of the furnace body 1, or the walls of the furnace body 1, the rotating shaft 2 are heated...

Abstract

The invention discloses a drying machine. The drying machine comprises a furnace body, rotating shafts, and stirring components, wherein the furnace body is arranged in the horizontal direction; the furnace body is provided with a feed opening through which materials are added and a discharge opening through which the materials are taken out; the rotating shafts are arranged in the cavity of the furnace body in a penetrating manner; the stirring components are arranged on the rotating shafts; the stirring components are used for stirring and crushing the materials in the axial directions of the rotating shafts and in the radial directions of the rotating shafts. According to the drying machine disclosed by the invention, when the materials are dried, under the driving of the rotating shafts, the stirring components can stir the materials in the axial directions of the rotating shafts and in the radial directions of the rotating shafts, so that the materials can be rolled in the furnace body in the axial directions of the rotating shafts and in the radial directions of the rotating shafts; besides, when the materials are stirred, the materials can also be crushed to form the materials with smaller particles, so that the area of heat convection between the materials and external environment is increased, the drying efficiency of the materials is improved, and the drying effect of the materials is improved.

Description

technical field [0001] The invention relates to the technical field of heating and drying in the environmental protection industry, in particular to a dryer. Background technique [0002] Sludge is the product of the sewage treatment process, which contains a large amount of organic matter, heavy metals and molds, etc. If no follow-up treatment is added, it will cause serious pollution to the environment. Therefore, it is often necessary to concentrate and dehydrate the sludge, but after this treatment The moisture content of the final sludge is usually above 70%, and the sludge needs to be further dried. [0003] Most of the drying furnaces used for sludge drying in the prior art are structured as the drying furnace disclosed in Chinese patent document CN201058838Y, including a furnace body, a transmission shaft arranged in the furnace body, and a radially extending shaft arranged on the outer wall of the transmission shaft. A number of hollow paddles are heated by passing...
