[0017] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0018] The utility model provides an anti-accumulation dehumidification dryer which is applied in the production and processing of TPU diaphragms.

[0019] Please refer to Figure 1 to Figure 2 As shown, an anti-deposition dehumidification dryer of the utility model comprises:

[0020] The dehumidifier barrel 1 has a feed inlet 11 and a discharge outlet 12 at the top and bottom respectively, and a first heating component 13 is provided inside the side wall;

[0021] The rotating shaft 2 passes through the top of the dehumidifier barrel 1. A second heating component 21 is provided inside the rotating shaft 2. A stirring blade group 22 is provided on the surface of the rotating shaft 2 extending into the inner cavity of the dehumidifier barrel 1. The angle between the stirring blade group 22 and the radial section of the rotating shaft 2 is an acute angle.

[0022] From the above description, it can be seen that the beneficial effect of the utility model is: an anti-accumulation dehumidification dryer, the first heating component 13 inside the side wall of the dehumidifier barrel 1 always heats the TPU diaphragm in the barrel from the outside, and at the same time, the TPU diaphragm is heated from the inside through the rotating shaft 2 in the inner cavity of the dehumidifier barrel 1, and the stirring blade group 22 on the rotating shaft 2 continuously turns up the TPU diaphragm to avoid accumulation and agglomeration of the TPU diaphragm, resulting in uneven heating, which affects the uniformity of dehumidification and drying of the TPU diaphragm.

[0023] In an optional embodiment, the first heating component 13 and the second heating component 21 are both electric heating tubes.

[0024] In an optional embodiment, the stirring blade group 22 includes more than two stages of stirring blades arranged at intervals along the axial direction of the rotating shaft 2 , and each stage of the stirring blades includes more than two blades arranged at intervals along the circumferential direction of the rotating shaft 2 .

[0025] In an optional embodiment, the blades of the stirring blades in two adjacent stages are staggered.

[0026] From the above description, it can be seen that since the TPU diaphragm has a large mass after accumulation, the inclination angle of the stirring blade should be between 7° and 15°. The TPU diaphragm is continuously and evenly stirred by the multi-stage stirring blades alternately arranged in the circumferential direction to avoid uneven heating of the TPU diaphragm at the bottom, which reduces the dehumidification and drying effect.

[0027] In an optional embodiment, the inner wall of the dehumidifier barrel 1 is provided with raised portions arranged in an array.

[0028] In an optional embodiment, the surface of the protrusion is a spherical surface.

[0029] From the above description, it can be seen that the design of the spherical raised portion can reduce the probability of the TPU diaphragm adhering to the inner wall of the barrel.

[0030] Please refer to Figure 1 to Figure 2 As shown, the first embodiment of the utility model is: an anti-deposition dehumidification dryer, comprising:

[0031] The dehumidifier barrel 1 has a feed inlet 11 and a discharge port 12 at the top and bottom respectively, both of which are provided with valves, and a first heating component 13 is provided inside the side wall;

[0032] The rotating shaft 2 passes through the top of the dehumidifier barrel 1. A second heating component 21 is provided inside the rotating shaft 2. A stirring blade group 22 is provided on the surface of the rotating shaft 2 extending into the inner cavity of the dehumidifier barrel 1. The angle between the stirring blade group 22 and the radial section of the rotating shaft 2 is an acute angle.

[0033] The first heating component 13 and the second heating component 21 are both electric heating tubes. The stirring blade group 22 includes more than two stages of stirring blades arranged axially and spaced apart along the rotating shaft 2, and each stage of the stirring blades includes more than two blades arranged circumferentially and spaced apart along the rotating shaft 2. The blades of the stirring blades of two adjacent stages are staggered. The inner wall of the dehumidifier barrel 1 is provided with raised portions arranged in an array. The surface of the raised portion is a spherical surface.

[0034] In summary, the first heating component inside the side wall of the dehumidifier barrel of the anti-accumulation dehumidification dryer of the utility model always heats the TPU diaphragm in the barrel from the outside. At the same time, the TPU diaphragm is heated from the inside through the rotating shaft in the inner cavity of the dehumidifier barrel. The stirring blade group on the rotating shaft continuously turns up the TPU diaphragm to avoid accumulation and agglomeration of the TPU diaphragm, resulting in uneven heating and affecting the uniformity of dehumidification and drying of the TPU diaphragm.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
