Material heat-treatment device

Abstract

The invention discloses a material heat-treatment device, which comprises a fixing unit, a rotary pipe group and a material pushing unit, wherein the fixing unit comprises two bases and an outer cylinder; the two bases are provided with a material containing space and a material hole communicated with the material containing space respectively; the material containing spaces are formed in the bases; the outer cylinder is provided with a temperature control space and an input port and an output port which are communicated with the temperature control space; the temperature control space is formed in the outer cylinder; the rotary pipe group comprises an inner pipe and a first power unit; the inner pipe is connected between the two bases rotatably and passes through the outer cylinder; the first power unit is used for driving the inner pipe to rotate relative to the bases and the outer cylinder; the material pushing unit comprises a rotary shaft, at least one helical blade and a second power unit; the rotary shaft is arranged in the inner pipe rotatably; the at least one helical blade is arranged on the surface of the rotary shaft; and the second power unit is used for driving the rotary shaft to rotate.

Description

technical field [0001] The invention relates to a material heat treatment device, in particular to a material heat treatment device with high thermal efficiency. Background technique [0002] Generally speaking, existing material heat treatment devices are usually used to perform various heat treatments on a material, such as thermal desorption (Desorption), pyrolysis (Pyrolysis), torrefaction (Torrefaction) or drying (Dryer) and other heat treatments, only need to adjust Different heat treatments can be carried out under different process conditions such as temperature or pressure. For example, if the material is oily soil, the oily soil can be thermally desorbed through the existing material heat treatment device, so that the organic or inorganic substances contained in the oily soil can be desorbed to reduce the The degree of contamination of oil-bearing soil; or, if the material is organic sludge, the organic sludge may be thermally cracked by the existing material heat...

Problems solved by technology

[0008] However, because the above-mentioned existing material heat treatment device No. I265052 also has the disadvantage of uneven temperature of the tube wall of the inner cylinder located on the same radial direction, the material is heated unevenly, and the pollutant desorption effect in the soil is not good. And the disadvantage of low thermal efficiency

[0009] Moreover, the above-mentioned existing material heat treatment device only drives the helical blade to push the material through the rotation of the rotating shaft, which has the disadvantage of poor stirring and mixing effect of the material, which will also affect the heat treatment effect of the material

Moreover, the inner cylinder of the existing material heat treatment device is also fixed to the outer cylinder, so it is easy to cause the disadvantage that the material adheres to the surface of the inner cylinder and accumulates fouling
