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 blanking mechanism 100 of the catalyst raw material mixing roll according to the embodiment of the present invention is described below with reference to the drawings.
Referring to fig. 1 to 5, the blanking mechanism of the catalyst raw material mixing mill according to the embodiment of the present invention includes a mixing barrel 110, a plugging disc 120, and a sealing ring 130.
Various kinds of powdery raw materials are uniformly mixed inside the mixing barrel 110 by a stirring mechanism (not shown in the figure), and then discharged through a discharge port 111 provided at the bottom of the mixing barrel 110, and a plugging disc 120 is installed at the discharge port 111 for sealing the discharge port 111 during the raw material mixing process.
The cylinder 140 is installed at the bottom of the mixing barrel 110, the telescopic end of the cylinder 140 extends and retracts along the axial direction of the mixing barrel 110, one end of the support frame 150 is fixed at the telescopic end of the cylinder 140, the blocking disc 120 is fixed on the support frame 150, and the blocking disc 120 is driven by the cylinder 140 to move away from or close to the discharge port 111, so that the discharge port 111 is opened and closed.
In this embodiment, the blocking disc 120 is provided with a clamping groove 121 along the circumferential direction for clamping the sealing ring 130, for example, the depth of the clamping groove 121 is equal to the outer diameter of the narrower end of the sealing ring 130, so as to ensure that the narrower end of the sealing ring 130 is flush with the outer circumferential surface of the blocking disc 120 after the sealing ring 130 is installed in the clamping groove 121.
In addition, the outer diameter of the plugging disc 120 is equal to the diameter of the discharge port 111, so that after the plugging disc 120 is installed on the discharge port 111, effective sealing of the discharge port 111 can be realized.
In the embodiment, the sealing ring 130 is clamped in the clamping groove 121 of the blocking disc 120 and has a tapered outer connection surface 131, and the lower end of the discharge port 111 has a tapered port 112 that is in interference fit with the outer connection surface 131.
Specifically, the sealing ring 130 is made of rubber and has certain elasticity, the sealing ring 130 has a long straight through hole, the sealing ring 130 is tightly hooped in the clamping groove 121, and when the external connection surface 131 of the sealing ring 130 is in interference fit with the port 112 of the discharge port 111, the wider end of the sealing ring 130 is located outside the discharge port 111, namely, a certain margin exists, and the sealing performance of the sealing ring 130 in fit with the discharge port 111 can be further adjusted.
Compared with the prior art, according to the utility model discloses catalyst raw materials mixing roll unloading mechanism 100 establishes the sealing washer 130 of conical structure through the cover on shutoff dish 120 to make interference fit between sealing washer 130 and the port 112 of the conical structure of discharge gate 111, simultaneously, guarantee that sealing washer 130 has certain installation allowance, can improve the sealed effect of discharge gate 111, avoid the raw materials to reveal.
In the above, the embodiments of the present invention have been described with reference to the drawings, but those skilled in the art to which the present invention pertains will appreciate that the present invention may be implemented in other ways without changing the technical idea or essential features of the present invention.
