Description

Technical Field

[0001] The utility model relates to the technical field of catalyst recovery, in particular to a catalyst recovery device. Background Art

[0002] Mercaptopropyltrimethoxysilane is a chemical with a mercapto functional group and can be used as a catalyst. Mercaptopropyltrimethoxysilane usually needs to be recovered after the catalysis is completed.

[0003] For example, a catalyst recovery device with patent number CN219849599U includes a device body, the device body is provided with one or more solvent separation structures, and the solvent separation structure separates the solvent from the treated catalyst; the solvent separation structure includes a lifting mechanism, a hose system and a pipeline; one end of the pipeline is connected to the top or side wall of the device body, and the pipeline is connected to the inside of the device body. The above document still has shortcomings. When in use, the hose system is driven to move along the pipeline by the lifting of the lifting mechanism. Under the drive of the liquid pump, the solvent at different heights in the device body is sucked out, so that the separation between the solvent and the treated catalyst is achieved. The hose system is lifted up and down, so the solvent can be directly sucked after the solid-liquid separation of the catalyst and the solvent. However, in the above document, the solid matter is filtered through the filter holes in the filter mechanism to prevent the solid matter from passing through, but the filter holes are easily blocked by solid matter during the filtering process, thereby affecting the passage of the liquid. At the same time, after the solvent and catalyst in the tank body are extracted, the inside of the tank body is prone to solid matter residue or adherence to the structure inside the tank body, which is not convenient for discharging the solid matter remaining in the tank body.

At this time, the spring drives the sliding bar to slide in the opposite direction under the action of elasticity, and the sliding bar drives the ball to move, and the ball knocks the filter mechanism. The elasticity causes the ball to continuously knock the filter mechanism under the action of elasticity, so that the filter mechanism itself is vibrated, so that the solid matter blocked in the filter hole is separated from the filter hole. During the filtration process, the filter hole will not be blocked by the solid matter, and thus will not affect the passage of the liquid.

[0024] The anti-blocking mechanism 3 includes a cross bar 301, a slide bar 302, a disc 303, a first spring 304 and a ball 305. The cross bar 301 is fixedly connected to the inside of the filter structure 7. The cross bar 301 is slidably connected to the outer wall of the slide bar 302. The slide bar 302 slides inside the cross bar 301. The upper end of the slide bar 302 is fixedly connected to the disc 303. The disc 303 drives the slide bar 302 to move.

The slide bar 302 drives the ball 305 to move. The outer wall of the ball 305 fits the filter structure 7.

[0025] When the liquid enters the interior of the filter mechanism 7 through the filter hole 8 and then enters the interior of the hose 6, it impacts the disc 303 and drives the disc 303 to move upward.

The electric push rod 401 drives the support plate 402 to move. The two support plates 402 are fixedly connected to the outer wall of the bottom cover 403. The two support plates 402 drive the bottom cover 403 to move. The upper surface of the bottom cover 403 is fixedly connected to the second disc 404. The outer wall of the second disc 404 is in clearance with the tank body 2. The second disc 404 and the bottom cover 403 are fixedly connected to the outer wall of the rubber ring 405. The rubber ring 405 increases the sealing performance of the connection between the bottom cover 403, the second disc 404 and the tank body 2.

[0027] The electric push rod 401 drives the support plate 402 to move, and the two support plates 402 drive the bottom cover 403 to move downward, and the bottom cover 403 drives the disc 2 404 and the rubber ring 405 to move, and the rubber ring 405 is separated from the tank body 2 to discharge the solid matter inside the tank body 2.

The filter mechanism 7 is first placed in the solvent to extract the solvent. The solvent enters the interior of the hose 6 through the filter hole 6. A container is used to receive the output end of the liquid extraction pump 13. Another container is used to contact the solvent and the mercaptopropyltrimethoxysilane catalyst at the layering point. The lifting mechanism 5 controls the filter mechanism 7 to descend in the mercaptopropyltrimethoxysilane catalyst, extract the mercaptopropyltrimethoxysilane catalyst, and use another container to contact the mercaptopropyltrimethoxysilane catalyst to complete the recovery of the catalyst. The filter hole 8 prevents solid matter from passing through.

The liquid pump 13 needs to be suspended when extracting the solvent, the mercaptopropyltrimethoxysilane catalyst and the stratification of the two. At this time, the spring 304 drives the slide bar 302 to slide in the opposite direction under the elastic action, and the slide bar 302 drives the ball 305 to move, and the ball 305 knocks the filter mechanism 7. The elastic 304 causes the ball 305 to continuously knock the filter mechanism 7 under the elastic action, so that the filter mechanism 7 itself vibrates, so that the solid matter blocked in the filter hole 8 is separated from the filter hole 8. During the filtering process, the filter hole will not be blocked by the solid matter, and thus will not affect the passage of the liquid;

The two support plates 402 drive the bottom cover 403 to move downward, and the bottom cover 403 drives the second disc 404 and the rubber ring 405 to move. The rubber ring 405 is separated from the tank body 2 to discharge the solid matter in the tank body 2. The rotating rod 10 prevents the solid matter from sticking to the inside of the tank body 2 when rotating. After the bottom of the tank body 2 is opened, the internal structure of the tank body 2 is flushed to prevent the solid matter from sticking to the structure inside the tank body 2. When in use, it is convenient to discharge the solid matter remaining in the tank body 2, and the electric push rod 402 is started in the reverse direction. The bottom cover 403 is fitted with the lower end of the tank body 2, and the second disc 404 is inserted into the inside of the tank body 2.
