[0002] Nylon 12, as a high-performance engineering plastic, is widely used in automobiles, electronics, medical devices and other fields. In its production process, hydrogenation reaction is a key process to improve product performance. The recovery and recycling of hydrogenation catalysts (such as Raney nickel, palladium on carbon catalysts, etc.) directly affect production costs and environmental benefits. Catalyst separation devices achieve the separation of catalysts and reaction products through processes such as filtration and separation.

[0003] The existing technology has the following problems: In existing equipment, the filtered product is discharged from the feed pipe. Most of the equipment lacks a clearing mechanism during the feeding process, which makes the feed pipe prone to blockage, requiring shutdown for maintenance and reducing separation efficiency. Utility Model Content

[0004] The main purpose of this invention is to provide a catalyst separation device for nylon 12 hydrogenation catalyst, which can effectively solve the problem that the feed pipe is easily blocked, requiring shutdown for maintenance and reducing separation efficiency.

[0017] The cleaning mechanism 12 includes a mounting shell 120, which is fixedly connected to the outside of the hopper 2. A lead screw 121 is rotatably connected inside the mounting shell 120. A threaded block 122 is threadedly connected to the outer circumference of the lead screw 121. A mounting plate 123 is fixedly connected to the outside of the threaded block 122.

[0029] like Figure 2 As shown, the brush 126 and the filter plate 6 abut against each other, and a handle 1210 is fixedly connected to one end of the screw 121.

[0030] It should be noted that the brush 126 and the filter plate 6 are in contact, the brush 126 can clean the filter plate 6, and the handle 1210 makes it convenient for the operator to turn the screw 121.

[0031] Working principle: The mixture after hydrogenation of nylon 12 is fed into silo 2. Motor 1 3 is started, and cam 4 pushes filter plate 6 to vibrate up and down. The catalyst is trapped above filter plate 6, and the filtered product is discharged through feed pipe 10. Motor 2 111 is started, and motor 2 111 drives turntable 112 to rotate. Turntable 112 drives eccentric shaft 113 to rotate. Eccentric shaft 113 drives moving frame 114 to move back and forth inside shell 110. Moving frame 114 drives rubber block 116 to repeatedly strike feed pipe 10 through connecting rod 115 to prevent blockage. When the plug is turned, the handle 1210 is rotated, which drives the lead screw 121 to rotate. The lead screw 121 drives the threaded block 122 to slide inside the mounting shell 120. The threaded block 122 drives the mounting plate 123 and the slider 129 to move along the guide rod 128. The mounting plate 123 drives the shell 124 to move. The shell 124 drives the brush 126 to clean the filter plate 6. The spring 125 ensures that the brush 126 is in contact with the filter plate 6.
