Description

TECHNICAL FIELD

[0001] The present application relates to the field of catalysts, and in particular to a high hydrophobic catalyst manufacturing equipment. BACKGROUND

[0002] High hydrophobic catalyst is a catalyst with significant hydrophobicity, its surface has low water affinity, which can effectively prevent water molecules from contacting the active sites of the catalyst during the reaction, thereby improving the efficiency and stability of the catalyst.

[0003] The invention patent with the authorized publication number CN100580983C discloses a hydrophobic catalyst layer of solid polymer fuel cell and its manufacturing method, solid polymer fuel cell and its manufacturing method, including dehydration condensation polymerization reaction between Si-OH groups which can even be carried out at room temperature; but it is preferred to add the operation of heating the catalyst layer after forming the hydrophobic agent.

[0004] In the industrial production process of hydrophobic catalyst, in order to ensure the performance stability and production efficiency of the catalyst product, heating treatment of the catalyst layer is the preferred process operation means. However, the drying equipment (usually drying box) applied in the heating process in the current prior art is usually configured with stirring paddle structure to drive the catalyst layer to form a flow state, so as to realize uniform heating of the catalyst layer.

[0005] However, practice shows that the stirring structure of the above-mentioned existing drying box has the following technical defects: due to the limitation of the power transmission path and structural characteristics of the stirring paddle, the effective stirring area formed during the rotation of the stirring paddle is highly concentrated in the peripheral area of the stirring paddle shaft, and for the catalyst layer distributed along the radial direction in the drying box, especially the edge area close to the inner wall of the drying box, the stirring paddle is difficult to drive this part of the catalyst layer to form sufficient flow.

[0006] This technical defect directly leads to the following series of problems: first, the catalyst layer in the drying box shows obvious uneven drying phenomenon, which is specifically manifested as significant difference in drying degree between the center area and the edge area of the catalyst layer, which cannot meet the process requirement of hydrophobic catalyst for uniform drying; second, in order to ensure that the catalyst layer in all areas reaches the qualified drying standard, the overall heating period needs to be prolonged, which leads to the extension of the production period of the hydrophobic catalyst; third, the extension of the production period directly increases the energy consumption, labor cost and time cost of the equipment, which ultimately causes the production cost of the hydrophobic catalyst to rise significantly, which is not conducive to the improvement of the economic efficiency and market competitiveness of the industrialized production of the hydrophobic catalyst.

The elastic force of the transmission elastic element 233 drives the table legs of the positioning table 21 to slide along the inner wall of the sliding cavity 13 towards the direction close to the cam 232, and the desktop of the positioning table 21 tends to abut against the surface of the cam 232. The air fan 24 drives the air in the drying cavity 11 to be discharged through the exhaust hole 12. The air in the drying cavity 11 impacts the blades of the transmission impeller 231 and drives the transmission impeller 231 to rotate, so as to drive the cam 232 to rotate and drive the table legs of the positioning table 21 to slide back and forth along the inner wall of the sliding cavity 13. The drying box 22 is placed on the desktop of the positioning table 21, so as to drive the catalyst layer in the drying box 22 to vibrate, so that the catalyst layer in the drying box 22 is not easy to be accumulated together, the drying speed of the catalyst layer is accelerated, the drying period of the catalyst layer is shortened, the production period of the high hydrophobic catalyst is reduced, and the production cost of the high hydrophobic catalyst is reduced.

[0050] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application. Any equivalent changes made on the basis of the structure, shape, principle of the present application shall be included in the protection scope of the present application.
