Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily implement the present invention. The present invention can be implemented in various different ways, and is not limited to the embodiments described below.

It is noted that the drawings are exemplary and are not drawn to scale. Relative dimensions and proportions between parts shown in the drawings have been shown exaggerated or reduced in size, for the sake of clarity and convenience in the drawings, any dimensions being exemplary only and not intended to limit the invention. In addition, in order to show similar features, the same components, elements, or parts shown in two or more drawings are denoted by the same reference numerals.

The embodiments of the present invention specifically show the preferred embodiments of the present invention. As a result, various modifications can be envisioned as shown in the drawings. Thus, embodiments are not limited to the particular manner in which the regions illustrated are modified, including for example, by variations in the manner in which the fabrication occurs.

The novel catalyst raw material mixing roll 100 according to the embodiment of the present invention is described below with reference to the drawings.

Referring to fig. 1 to 4, the novel catalyst raw material mixing mill according to an embodiment of the present invention includes a housing 110, a top cover 120, a mixing barrel 130, and a sealing plate 140.

The casing 110 is cylindrical as a whole, the top cover 120 is installed at an opening at the upper end of the casing 110, the top cover 120 is provided with a feed inlet 121, the mixing barrel 130 is rotatably installed in the cavity of the casing 110, the bottom of the mixing barrel 130 is provided with a discharge outlet 134 penetrating the bottom plate of the casing 110, and a sealing plate 140 having a cylindrical structure for sealing is disposed between the mixing barrel 130 and the top cover 120.

In this embodiment, an annular slot 131 is formed on the upper end surface of the mixing barrel 130, and an inner pad 132 and an outer pad 133 are fixed on the inner and outer sidewalls of the slot 131.

Specifically, the inner pad 132 and the outer pad 133 each have a certain elasticity, and the inner pad 132 and the outer pad 133 are rubber pads, for example.

The inner pad 132 is bonded to the inner sidewall of the card slot 131, the outer pad 133 is bonded to the outer sidewall of the card slot 131, and a certain gap is formed between the inner pad 132 and the outer pad 133, which is smaller than the thickness of the sealing plate 140, for example.

In this embodiment, the inner pad 132 and the outer pad 133 have corresponding arcuate outer surfaces, i.e., the opposite sides of the inner pad 132 and the outer pad 133 are arcuate surfaces.

The sealing plate 140 is fixedly attached to the lower surface of the top cover 120, and the lower end of the sealing plate 140 extends into the catching groove 131 and is clamped between the inner pad 132 and the outer pad 133.
