Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of benzene hydrogenation catalysts, in particular to a regeneration mixing and separation system for benzene hydrogenation catalysts. Background Art
[0002] There are two production methods for benzene hydrogenation catalysts: NCG type: nickel metal is treated with nickel and added to aluminum-containing solution for co-precipitation, and the finished product is obtained through washing, filter pressing, calcination, tableting and pre-reduction. Pt catalyst: aluminum salt is neutralized and precipitated, and then washed, filter pressed, dried and formed. The formed carrier is impregnated with platinum, and then dried and calcined to obtain the finished product.
[0003] During the regeneration and mixing separation of the benzene hydrogenation catalyst, there is a filter press process. However, after multiple filtrations, some solids generated by the catalyst will remain on the filter plate, causing the filter to become clogged, reducing the fluidity of the liquid and slowing down the solid-liquid separation process.
[0004] To this end, we propose a hybrid separation system for benzene hydrogenation catalyst regeneration. Utility Model Content

[0024] like Figure 1-Figure 2 As shown, the threaded rod 8 extends to the outside of the device body 1 and is fixedly connected to the driving device 4, and a guide rod 9 is fixedly installed below the threaded rod 8. The guide rod 9 passes through the moving block 12, and both ends of the guide rod 9 are fixedly connected to the inner wall of the device body 1. The output end of the driving device 4 is fixedly connected to the threaded rod 8. When the staff turns on the driving device 4, the threaded rod 8 rotates, thereby driving the cleaning scraper 13 to move horizontally. By arranging the guide rod 9 below the threaded rod 8 and the guide rod 9 passing through the moving block 12, the moving block 12 moves in a straight line and does not have a large position offset.

By providing the feed pipe 2 and extending the feed pipe 2 into the inside of the device body 1, it is convenient for the staff to filter the catalyst product that needs to be filtered. By providing the discharge pipe 3 and extending the discharge pipe 3 into the inside of the device body 1, after the solid and liquid are separated after the filter pressing is completed, the liquid flows out from the discharge pipe 3, which is convenient for the staff to collect.

An electric telescopic rod 5 is fixedly installed on the upper surface of the device body 1, and a pressing plate 6 is fixedly installed on the lower surface of the electric telescopic rod 5.

When the threaded rod 8 rotates, the moving block 12 moves horizontally. A cleaning scraper 13 is fixedly installed on the lower surface of the moving block 12. When the moving block 12 moves horizontally, the cleaning scraper 13 is driven to move, so that the cleaning scraper 13 can clean the solid debris on the filter screen 10, thereby avoiding clogging of the filter screen 10 and slowing down the liquid circulation speed. At the same time, the staff turns on the external power supply so that The electric telescopic rod 5 moves vertically, thereby driving the pressing plate 6 to move vertically. When the pressing plate 6 moves downward, it squeezes the objects on the filter plate 7, so that the catalyst product is fully filtered, so that the solids remain on the filter plate 7, which is convenient for the staff to collect. The filter holes on the filter plate 7 are larger than the filter holes on the filter screen 10, so that the remaining liquid mixed with solids continues to flow downward. When the cleaning scraper 13 slides, it also drives the solid debris on the filter screen 10 to move, so that the debris on the filter screen 10 falls into the collection box 11, and the collection box 11 can be slid out by the pulley 14, which is convenient for the staff to collect the remaining solid debris.
