DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0021] Embodiment

[0022] Refer to Figures 1 to 4 , a powder diversion device for pneumatic conveying of the present utility model includes a box 8 and a box cover plate 1 fixedly connected to the top of the box 8. A guide cover 4 is fixedly installed inside the box 8, and a guide cover lining 5 is fixedly bonded inside the guide cover 4 by ceramic glue. Both the guide cover 4 and the guide cover lining 5 are arc-shaped shell structures. A feed pipe 9 corresponding to the position of the guide cover lining 5 is fixedly installed on one side of the box 8.

[0023] The box cover 1 and the box body 8 are fixedly connected by a flange, and a cover seal ring 2 is installed between the box cover 1 and the box body 8 to prevent material leakage.

[0024] The inner wall of the box body 8 is fixedly bonded with a box body ceramic sticker 7 through ceramic glue, and a ceramic inner liner tube 10 is fixedly bonded in the feed pipe 9 through ceramic glue, so as to ensure that the material is in contact with the ceramic uniformly. This not only improves the anti-wear performance of the whole device, but also avoids the introduction of metal foreign objects. At the same time, the ends of the feed pipe 9 and the ceramic inner liner tube 10 are matched by a boss structure 11 to prevent the ceramic inner liner tube 10 from axially displacing and improve the reliability of installation.

[0025] A guide cover support 3 is fixedly connected to the bottom of the box cover 1, a guide cover 4 is fixedly connected to the guide cover support 3, and a guide cover inner liner 5 is fixedly connected to the guide cover 4. Therefore, during maintenance, when the box cover 1 is opened, the guide cover 4 and the guide cover inner liner 5 can be taken out together, which is convenient for maintenance.

[0026] The guide cover inner liner 5 is composed of an arc-shaped ceramic plate 501 and ceramic side plates 502 symmetrically fixed on both sides of the arc-shaped ceramic plate 501. The connection between the arc-shaped ceramic plate 501 and the ceramic side plates 502 is matched by a boss structure 11 to prevent the installation positions of the arc-shaped ceramic plate 501 and the ceramic side plates 502 from changing, so as to form a seamless splicing and avoid the phenomenon of material blockage at the connection position.

[0027] The ceramic side plate 502 is fixedly connected to the side plate of the guide cover 4 through a U-shaped strip 6 to further improve the connection firmness between the guide cover 4 and the guide cover inner liner 5.

[0028] Counterbores 12 are provided on the guide cover 4 and the guide cover inner liner 5. After the countersunk head screws pass through the counterbores 12, the guide cover 4 is fixedly connected to the guide cover support 3, so that the countersunk head screws are hidden in the counterbores 12 to avoid wear of the countersunk head screws under the action of air pressure.

[0029] In this embodiment, the box cover 1, the box body 8, the feed pipe 9 and the guide cover 4 are all made of 6061 series aluminum alloy materials to reduce the weight of the device; at the same time, a handle is welded on the box cover 1 to facilitate taking out the guide cover 4 and the guide cover inner liner 5 during maintenance.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. For those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and all such modifications and replacements should fall within the protection scope of the appended claims of the present invention.
