Description

Technical Field

[0001] This utility model relates to the field of metal catalyst separation technology, and in particular to a metal catalyst separation device. Background Technology

[0002] For example, Chinese patent CN221951411U discloses a metal catalyst separation device that uses a magnetic strip to adsorb the metal catalyst. The unwanted part slides into a collection box through an inclined surface for secondary separation. After the metal catalyst is adsorbed, the magnetic strip continues to rotate to the other side, and a scraper scrapes off the magnetic strip. The material that is needed falls into the recycling box by gravity to complete the recycling, thus improving the recycling efficiency.

[0003] The aforementioned application uses the magnetic force of a magnetic strip to adsorb the metal catalyst in the falling reaction liquid, and then scrapes off the adsorbed metal catalyst on the magnetic strip for collection. The reaction liquid is first injected into the funnel, but its feed rate is limited, resulting in low separation efficiency when a large amount of reaction liquid needs to be processed. If the feed rate of the funnel is increased, the excessively fast flow rate will cause a large amount of metal catalyst to not be captured by the magnetic strip in time, which will still reduce the separation efficiency. Furthermore, scraping off the metal catalyst on the magnetic strip by the scraper will inevitably leave metal catalyst residue, which will greatly reduce the separation efficiency of the magnetic strip after long-term use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a metal catalyst separation device that solves the technical problem of low separation efficiency of metal catalysts in reaction solutions and unsuitability for large-scale reaction solution processing, thereby achieving the goal of improving the separation efficiency of metal catalysts.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a metal catalyst separation device, including a filter box installed at the bottom of a separation tank, wherein the separation tank is provided with a separation mechanism for magnetic adsorption of metal catalyst in the reaction liquid, and the filter box is provided with a filtration mechanism for filtering and separating large particles of metal catalyst remaining in the reaction liquid.

[0006] The separation mechanism includes a magnetic ring installed in an installation cavity inside the separation tank. A rotating shaft is rotatably connected to a rotating hole at the top of the separation tank, and multiple sets of stirring rods are vertically arrayed on the rotating shaft. A drive motor is installed on the separation tank to drive the rotating shaft to rotate. The stirring rods are equipped with cutting and turbulence components to cut and disperse the metal catalyst particles that form the colloidal solution.

[0007] A further improvement is that the cutting and turbulence-disrupting assembly includes a U-shaped connecting rod mounted on a stirring rod, and a rotating cylinder is sleeved on the U-shaped connecting rod, on which multiple sets of cutting blades are arrayed.

[0008] A further improvement is that an inlet hopper is installed on the top of the separation tank, and a drain pipe extending into the filter box is installed at the bottom of the separation tank, with an electric sealing valve installed on the drain pipe.

[0009] A further improvement is that the filtration mechanism includes a filter plate installed at an incline in the filter box, and the filter plate has an array of through-holes. A discharge pipe is installed on the filter box at the lowest incline of the filter plate, and a liquid discharge pipe is installed at the bottom of the back of the filter box. A vibration component is provided in the filter box below the filter plate to drive the filter plate to vibrate and avoid clogging the filter holes by metal catalyst particles.

[0010] A further improvement is that the vibration assembly includes a filter plate rotatably connected to the filter box at its left end via a rotating shaft, and a vibration motor is installed on the bottom right side of the filter plate. Vibration springs are installed at both the front and rear ends of the bottom right side of the filter plate, and a support plate is installed on the inner wall of the filter box to provide support for the vibration springs.

[0011] A further improvement is that the filter box is equipped with an observation window made of transparent tempered glass, and the separation tank is equipped with a controller to control the operation of the separation mechanism and the filter mechanism.

[0012] By employing the above technical solution, this utility model provides a metal catalyst separation device, which has at least the following beneficial effects:

[0013] 1. This utility model uses an electric current to generate magnetic adsorption force on a magnetic ring, which adsorbs metal catalyst particles in the reaction liquid in the separation tank onto the tank wall. With the help of a rotating stirring rod, the metal catalyst particles in the reaction liquid are more evenly distributed in the separation tank and are in a dynamic state, making them easier to be captured and adsorbed onto the tank wall by the magnetic ring. This enables large-scale adsorption and separation of metal catalysts in the reaction liquid.

[0014] 2. This utility model uses the rotation of the stirring rod to drive the rotating cylinder on the U-shaped connecting rod to contact the reaction liquid and be driven to rotate by the liquid flow, thereby driving the cutting blade assembly to rotate, cutting and turbulent the colloidal solution, and improving the adsorption and separation effect of the magnetic ring.

[0015] 3. This utility model uses a vibrating motor to drive the filter plate to swing up and down around the pivot point on the left side of the filter plate under the pull of the vibrating spring, thereby shaking out the metal catalyst particles in the filter holes on the filter plate and discharging them through the discharge pipe, thus avoiding the metal catalyst particles from clogging the filter holes on the filter plate.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Given the low efficiency of existing technologies for separating metal catalysts from reaction solutions, which are unsuitable for large-scale reaction solution processing, this embodiment provides a metal catalyst separation device. Please refer to... Figures 1-4 This embodiment provides a metal catalyst separation device that can improve the separation efficiency of metal catalysts. The metal catalyst separation device includes a filter box 2 installed at the bottom of a separation tank 1. The separation tank 1 is equipped with a separation mechanism 3 for magnetic adsorption of metal catalysts in the reaction solution. The filter box 2 is equipped with a filter mechanism 4 for filtering and separating large particles of metal catalyst remaining in the reaction solution. The separation mechanism 3 magnetically adsorbs the metal catalysts in the reaction solution within the separation tank 1, while larger particles that are agitated and fall off are collected by the filter mechanism 4.

[0032] Because existing technologies have low efficiency in separating metal catalysts from reaction solutions and are not suitable for large-scale reaction solution processing, this device is equipped with a separation mechanism 3. The separation mechanism 3 includes a magnetic ring 31 installed in an installation cavity inside the separation tank 1. A rotating shaft 32 is rotatably connected to a rotating hole at the top of the separation tank 1, and multiple sets of stirring rods 33 are vertically arrayed on the rotating shaft 32. A drive motor 34 is installed on the separation tank 1 to drive the rotating shaft 32 to rotate. The stirring rods 33 are equipped with a cutting and turbulence-dispersing component 35 to cut and disperse the metal catalyst particles that form a colloidal solution. When the magnetic ring 31 is energized, it generates a magnetic adsorption force, adsorbing the metal catalyst particles in the reaction solution inside the separation tank 1 onto the tank wall. At this time, the drive motor 34 is started to drive the rotating shaft 32 to rotate, which in turn drives the stirring rods 33 to rotate, so that the metal catalyst particles in the reaction solution are more evenly distributed in the separation tank and are in a dynamic state, making it easier for them to be captured and adsorbed onto the tank wall by the magnetic ring 31, thereby realizing the large-scale adsorption and separation of metal catalysts in the reaction solution.

[0033] Because some metal catalyst particles are small, they may form a stable colloidal solution during stirring, which is difficult to be effectively adsorbed by the magnetic ring 31. Therefore, the device is also equipped with a cutting and turbulence-disrupting component 35. The cutting and turbulence-disrupting component 35 includes a U-shaped connecting rod 351 installed on the stirring rod 33, and a rotating cylinder 352 is sleeved on the U-shaped connecting rod 351. Multiple sets of cutting blades 353 are arrayed on the rotating cylinder 352. When the stirring rod 33 rotates, it drives the rotating cylinder 352 on the U-shaped connecting rod 351 to contact the reaction liquid and rotate due to the liquid flow. This, in turn, drives the cutting blades 353 to rotate, cutting and turbulent the colloidal solution, thereby improving the adsorption and separation effect of the magnetic ring 31.

[0034] The top of the separator 1 is equipped with an inlet hopper 36, and the bottom of the separator 1 is equipped with a drain pipe 37 that extends into the filter box 2. An electric sealing valve 38 is installed on the drain pipe 37. The reaction liquid is injected into the separator 1 through the inlet hopper 36, and the opening of the drain pipe 37 is controlled by the electric sealing valve 38, so that the reaction liquid after preliminary separation can be introduced into the filter box 2 for secondary filtration.

[0035] The filter box 2 is equipped with an observation window 51 made of transparent tempered glass. Through the observation window 51, it is possible to observe in real time whether the filter holes on the filter plate 41 are blocked. The separation tank 1 is equipped with a controller 52 that controls the operation of the separation mechanism 3 and the filter mechanism 4. The normal operation of the device is controlled by the controller 52.

[0036] Example 2

[0037] Because larger metal catalyst particles may be torn off the wall of separator 1 during agitation, therefore, based on Example 1, as follows... Figures 1-4 As shown, the device is also equipped with a filtration mechanism 4, which includes a filter plate 41 installed at an incline in the filter box 2, and filter holes are arrayed through the filter plate 41. A discharge pipe 42 is installed on the filter box 2 at the lowest incline of the filter plate 41, and a liquid discharge pipe 43 is installed at the bottom back of the filter box 2. A vibration component 44 is installed in the filter box 2 below the filter plate 41 to drive the filter plate 41 to vibrate and prevent metal catalyst particles from clogging the filter holes. When the reaction liquid flows into the filter box 2, it passes through the filter plate 41 and filters and separates the larger metal catalyst particles in the reaction liquid through the filter holes opened on the filter plate 41, thereby realizing the secondary screening and separation of the metal catalyst.

[0038] To prevent metal catalyst particles from clogging the filter holes on the filter plate 41, the device is also equipped with a vibration assembly 44. The vibration assembly 44 includes a filter plate 41 rotatably connected to the filter box 2 at its left end via a rotating shaft. A vibration motor 441 is installed on the bottom right side of the filter plate 41. Vibration springs 442 are installed at both the front and rear ends of the bottom right side of the filter plate 41. A support plate 443 is installed on the inner wall of the filter box 2 to support the vibration springs 442. When the vibration motor 441 is started, the filter plate 41 is driven to swing up and down around the rotating shaft on the left side of the filter plate 41 under the pull of the vibration springs 442, thereby vibrating out the metal catalyst particles in the filter holes on the filter plate 41 and discharging them through the discharge pipe 42.
