[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a magnetic recyclable DBM catalyst preparation device, including a stirring tank 1 and a separating tank 2. The stirring tank 1 is equipped with a multi-axis paddle stirring mechanism 3, which is used to stir the reaction solution and scrape off the reactants adhering to the inner wall. The separating tank 2 is equipped with a magnetic separation box mechanism 4, which is used to separate the magnetic catalyst. The top of the outer wall of the stirring tank 1 is equipped with a snap-fit ​​fixing mechanism 5, the left side of the outer wall of the stirring tank 1 is equipped with a pH monitoring mechanism 6, and the inner wall of the stirring tank 1 is equipped with a heating mechanism 7.

[0034] The multi-shaft paddle stirring mechanism 3 includes a box cover 31, the bottom of which is located at the top of the mixing box 1. An engine 32 is fixedly connected to the top of the box cover 31. A rotating rod 33 is fixedly connected to the output end of the engine 32. Two crossbars 34 are fixedly connected to the top of the outer wall of the rotating rod 33. Multiple scrapers 35 are fixedly connected to the left and right ends of the two crossbars 34 and the bottom end of the rotating rod 33. A stirring fan blade assembly 36 is provided on the outer wall of the rotating rod 33. A solution transport pipe assembly 37 is provided on the outer walls of both the mixing box 1 and the separating tank 2.

[0035] Specifically, during equipment operation, the raw materials required for the reaction are injected into the mixing tank 1. The tank cover 31 is fixed to the top of the mixing tank 1 by the snap-locking mechanism 5 to ensure that the reaction space is sealed. The engine 32 is started, and its output end drives the rotating rod 33 to rotate. The stirring fan blade assembly 36 on the outer wall of the rotating rod 33 rotates with it to stir the reaction solution in the mixing tank 1, so that the raw materials can fully contact and react. While the rotating rod 33 rotates, the two horizontal bars 34 on the top of its outer wall rotate synchronously. The left and right ends of the horizontal bars 34 and the multiple scrapers 35 at the bottom of the rotating rod 33 move accordingly. The scrapers 35 are in contact with the inner wall of the mixing tank 1 to scrape off the reactants adhering to the inner wall, avoiding the waste caused by raw material residue, and ensuring the uniform concentration of the reaction system.

[0036] During the reaction, the heating mechanism 7 heats the inside of the mixing tank 1 to maintain the required reaction temperature; the pH monitoring mechanism 6 monitors the acidity and alkalinity of the reaction solution in real time, so that the operator can make timely adjustments. After the reaction is completed, the solution transport pipe assembly 37 transports the mixed solution in the mixing tank 1 to the separatory tank 2. The magnetic separation box mechanism 4 is activated and processes the mixed solution in the separatory tank 2 through its own magnetic field, adsorbing and separating the magnetic catalyst in it, thereby achieving the separation of the catalyst from the reaction solution. Through the stirring and scraping action of the multi-shaft paddle stirring mechanism 3 and the separation action of the magnetic separation box mechanism 4, the preparation process of the magnetic recyclable DBM catalyst is completed.

[0037] Reference Figure 1 , Figure 2 and Figure 5 The magnetic separation box mechanism 4 includes a second engine 41. The rear side of the second engine 41 is fixedly connected to the front side of the outer wall of the liquid separator 2. A magnetic roller 42 is fixedly connected to the output end of the second engine 41. A slag discharge platform 43 is fixedly connected to the bottom of the inner wall of the liquid separator 2. A discharge channel 44 runs through the left side of the outer wall of the liquid separator 2. A rubber pressure roller assembly 45 is provided at the front and rear ends of the top of the inner wall of the liquid separator 2.

[0038] Specifically, after the mixed solution is transported to the dispensing tank 2 through the solution transport pipe assembly 37, the engine 41 is started, and its output end drives the magnetic roller 42 to rotate. During the rotation of the magnetic roller 42, the magnetic catalyst in the mixed solution is adsorbed, so that the magnetic catalyst is attached to the surface of the magnetic roller 42. As the magnetic roller 42 rotates, the part with the adsorbed magnetic catalyst leaves the mixed solution area. The rubber pressure roller assembly 45 set at the front and rear ends of the top of the inner wall of the dispensing tank 2 comes into contact with the surface of the magnetic roller 42.

[0039] When the magnetic roller 42 rotates, its surface is squeezed, and the magnetic catalyst is peeled off from the surface of the magnetic roller 42. The peeled magnetic catalyst falls onto the slag discharge platform 43. Guided by the slag discharge platform 43, the magnetic catalyst moves towards the discharge channel 44 and is finally discharged from the liquid separator 2 through the discharge channel 44. The separation and collection of the magnetic catalyst in the mixed solution are achieved by the adsorption effect generated by the rotation of the magnetic roller 42 driven by the engine 41, the squeezing and peeling effect of the rubber pressure roller assembly 45, and the guiding effect of the slag discharge platform 43.

[0040] Reference Figure 1 , Figure 3 and Figure 5 The stirring fan blade assembly 36 includes multiple rotating shafts 361, the inner walls of which are fixedly connected to the outer wall of the rotating rod 33, and multiple blades 362 are fixedly connected to the outer walls of the multiple rotating shafts 361. The solution transport pipe assembly 37 includes two feed pipes 371, the bottoms of which are both through the top of the box cover 31. The bottom left side of the outer wall of the stirring box 1 is through the transport pipe 372, the left side of the transport pipe 372 is through the right side of the outer wall of the liquid separator 2, and the bottom front side of the outer wall of the liquid separator 2 is through the waste pipe 373. The rubber pressure roller assembly 45 includes a rotating roller 451, the front and rear ends of which are rotatably connected to the front and rear sides of the inner wall of the liquid separator 2, and a rubber roller 452 is fixedly connected to the outer wall of the rotating roller 451.

[0041] Specifically, when the engine 32 drives the rotating rod 33 to rotate, multiple rotating shafts 361 on the outer wall of the rotating rod 33 rotate synchronously, driving multiple blades 362 on the outer wall of each rotating shaft 361 to make circular motion around the axis of the rotating rod 33. During the rotation, the blades 362 apply shear force and thrust to the reaction solution, causing the solution to form a vortex in the mixing tank 1. Through the distributed arrangement of multiple rotating shafts 361 and the circular motion of the blades 362, the multi-dimensional mixing of the reaction solution is achieved. The reaction raw materials are transported to the mixing tank 1 through two feed pipes 371. The bottom of the feed pipes 371 penetrates the tank cover 31 to ensure that the raw materials are directly injected into the reaction area.

[0042] After the reaction is completed, the solution is transported from the mixing tank 1 to the separating tank 2 through the conveying pipe 372. The two ends of the conveying pipe 372 pass through the bottom left side of the mixing tank 1 and the right side of the separating tank 2, respectively. The solution is directed to flow by means of liquid level difference and pressure difference. The waste separated in the separating tank 2 is discharged through the waste pipe 373. The waste pipe 373 passes through the bottom front side of the separating tank 2 to facilitate the gravity discharge of the waste.

[0043] During the magnetic separation process, after the magnetic roller 42 rotates and adsorbs the magnetic catalyst, the rotating roller 451 rotates freely under the support of the front and rear sides of the inner wall of the separating tank 2. The rubber roller 452 on its outer wall contacts the surface of the magnetic roller 42. When the magnetic roller 42 carrying the magnetic catalyst rotates to the contact area with the rubber roller 452, the rubber roller 452 applies pressure to the surface of the magnetic roller 42. Through the rotation of the rotating roller 451 and the squeezing of the rubber roller 452, the magnetic catalyst is peeled off from the surface of the magnetic roller 42. The peeled catalyst falls to the slag discharge platform 43 and is discharged through the discharge channel 44, thus realizing the separation of the magnetic catalyst from the solution.

[0044] Reference Figure 1 , Figure 2 and Figure 4 The buckle fixing mechanism 5 includes multiple movable buckles 51, which are fixedly connected to the top of the outer wall of the mixing tank 1. Multiple ring clips 52 are fixedly connected to the outer wall of the tank cover 31. The pH monitoring mechanism 6 includes a pH monitor 61, which is fixedly connected to the left side of the outer wall of the mixing tank 1 on the right side. An electrode tube 62 is fixedly connected to the right side of the pH monitor 61, and the right side of the electrode tube 62 passes through the left side of the outer wall of the mixing tank 1. The heating mechanism 7 includes a heat transfer wall 71, which is fixedly connected to the top of the inner wall of the mixing tank 1 on the top of the outer wall. Multiple heating tubes 72 are fixedly connected to the outer wall of the heat transfer wall 71.

[0045] Specifically, when the lid 31 is placed on top of the mixing tank 1, multiple movable buckles 51 are combined with corresponding ring clips 52. One end of the movable buckle 51 is fixed to the top of the outer wall of the mixing tank 1. By rotating it, it is made to engage with the ring clip 52 on the outer wall of the lid 31. Through the synchronous engagement of multiple movable buckles 51 and ring clips 52, the lid 31 and the mixing tank 1 are sealed together. During the reaction, the pH monitor 61 monitors the reaction solution in the mixing tank 1 in real time through the electrode tube 62. One end of the electrode tube 62 is connected to the pH monitor 61, and the other end penetrates the left side wall of the mixing tank 1 and is immersed in the solution. The pH of the solution is converted into an electrical signal and transmitted to the pH monitor 61. Through the electrochemical induction of the electrode tube 62 and the data processing of the pH monitor 61, the pH of the reaction solution is monitored in real time.

[0046] The heat transfer wall 71 of the heating mechanism 7 covers the top of the inner wall of the mixing tank 1, and multiple heating tubes 72 are evenly distributed on the outer wall of the heat transfer wall 71. When the heating tubes 72 are energized, the heat generated is conducted to the inside of the mixing tank 1 through the heat transfer wall 71, causing the reaction solution to heat up. Through the even distribution of multiple heating tubes 72 and the heat conduction effect of the heat transfer wall 71, the reaction solution is evenly heated. When the pH monitor 61 detects that the acidity or alkalinity of the solution deviates from the preset range, the operator can adjust the reaction conditions through external adjustment. When it is necessary to terminate the reaction or perform cleaning, the engagement of the movable buckle 51 and the ring clamp 52 can be loosened to separate the tank cover 31 from the mixing tank 1. Through the mechanical fixation of the movable buckle 51 and the ring clamp 52, the electrochemical monitoring of the electrode tube 62 and the pH monitor 61, and the heat conduction of the heating tubes 72 and the heat transfer wall 71, the sealing of the reaction environment, parameter monitoring and temperature control are achieved.

[0047] Working principle: Before the equipment is started, the lid 31 is placed on top of the mixing tank 1. At this time, the buckle fixing mechanism 5 starts to operate. Multiple movable buckles 51 are fixedly connected to each other on the top of the outer wall of the mixing tank 1. Multiple ring clips 52 are fixedly connected to the outer wall of the lid 31. By rotating, the movable buckles 51 are engaged with the corresponding ring clips 52. Through the synchronous engagement of multiple movable buckles 51 and ring clips 52, the lid 31 and the mixing tank 1 are sealed, providing a sealed space for subsequent reactions.

[0048] Subsequently, the raw materials required for the reaction are injected into the mixing tank 1 through the two feed pipes 371 of the solution transport pipe assembly 37. The bottoms of both feed pipes 371 extend through the top of the tank cover 31, ensuring that the raw materials are directly injected into the reaction area of ​​the mixing tank 1. After the raw materials are injected, the engine 32 of the multi-shaft paddle stirring mechanism 3 is started. A rotating rod 33 is fixedly connected to the output end of the engine 32. When the engine 32 runs, it drives the rotating rod 33 to rotate. Two crossbars 34 are fixedly connected to the top of the outer wall of the rotating rod 33. Multiple scrapers 35 are fixedly connected to the left and right ends of the two crossbars 34 and the bottom end of the rotating rod 33. When the rotating rod 33 rotates, the crossbars 34 rotate synchronously with it, thereby driving the scrapers 35 to move. The scrapers 35 adhere to the inner wall of the mixing tank 1, removing the sticky material. The reactants attached to the inner wall are scraped off. At the same time, a stirring blade assembly 36 is fixedly connected to the outer wall of the rotating rod 33. The stirring blade assembly 36 includes multiple rotating shafts 361. The inner walls of the multiple rotating shafts 361 are fixedly connected to the outer wall of the rotating rod 33. Multiple blades 362 are fixedly connected to the outer walls of the multiple rotating shafts 361. The rotation of the rotating rod 33 drives the rotating shafts 361 to rotate, thereby causing the blades 362 to make circular motion around the axis of the rotating rod 33. During the rotation, the blades 362 apply shear force and thrust to the reaction solution, causing the solution to form a vortex in the stirring tank 1. Through the distributed arrangement of multiple rotating shafts 361 and the circular motion of the blades 362, combined with the scraping action of the scraper 35, the reaction raw materials are uniformly mixed, ensuring that each raw material is fully contacted and reacts.

[0049] During the reaction, a heating mechanism 7 is installed on the inner wall of the stirring tank 1. The heating mechanism 7 includes a heat transfer wall 71, the top of which is fixedly connected to the top of the inner wall of the stirring tank 1. Multiple heating tubes 72 are fixedly connected to the outer wall of the heat transfer wall 71. When the heating tubes 72 are energized, they generate heat, which is conducted to the interior of the stirring tank 1 through the heat transfer wall 71, providing suitable temperature conditions for the reaction. Through the uniform distribution of the multiple heating tubes 72 and the heat conduction effect of the heat transfer wall 71, uniform heating of the reaction solution is achieved. Simultaneously, a pH monitoring mechanism 6 is installed on the left side of the outer wall of the stirring tank 1. The pH monitoring mechanism 6 includes... A pH monitor 61 is fixedly connected to the left side of the outer wall of the mixing tank 1 on its right side. An electrode tube 62 is fixedly connected to the right side of the pH monitor 61. The right side of the electrode tube 62 penetrates the left side of the outer wall of the mixing tank 1 and is immersed in the reaction solution. The electrode tube 62 converts the acidity and alkalinity of the solution into an electrical signal and transmits it to the pH monitor 61. Through the electrochemical induction of the electrode tube 62 and the data processing of the pH monitor 61, the acidity and alkalinity of the reaction solution can be monitored in real time. This allows the operator to adjust the reaction conditions in a timely manner through external adjustment when the pH monitor 61 detects that the acidity and alkalinity of the solution deviates from the preset range.

[0050] After the reaction is completed, the solution transport pipe assembly 37 starts to work. The bottom left side of the outer wall of the mixing tank 1 is connected to the transport pipe 372. The left side of the transport pipe 372 is connected to the right side of the outer wall of the separator 2. The mixed solution is transported from the mixing tank 1 to the separator 2 through the transport pipe 372. The directional flow of the solution is achieved by using the liquid level difference and pressure difference.

[0051] After the mixed solution enters the separatory tank 2, the magnetic separation tank mechanism 4 is activated. The magnetic separation tank mechanism 4 includes a second engine 41, the rear of which is fixedly connected to the front of the outer wall of the separatory tank 2. A magnetic roller 42 is fixedly connected to the output end of the second engine 41. When the second engine 41 is activated, its output end drives the magnetic roller 42 to rotate. During the rotation of the magnetic roller 42, the magnetic catalyst in the mixed solution is adsorbed, causing the magnetic catalyst to adhere to the surface of the magnetic roller 42. As the magnetic roller 42 rotates, the part with the adsorbed magnetic catalyst leaves the mixed solution area. A rubber pressure roller assembly 45 is provided on the inner wall of the separatory tank 2. The rubber pressure roller assembly 45 includes a rotating roller 451, the front and rear ends of which are rotatably connected. A rubber roller 452 is fixedly connected to the outer wall of the rotating roller 451 on the front and rear sides of the inner wall of the separator 2. The rubber roller 452 is in contact with the surface of the magnetic roller 42. When the magnetic roller 42 carrying the magnetic catalyst rotates to the contact area with the rubber roller 452, the rubber roller 452 applies pressure to the surface of the magnetic roller 42. Through the rotation of the rotating roller 451 and the squeezing of the rubber roller 452, the magnetic catalyst is peeled off from the surface of the magnetic roller 42. The peeled magnetic catalyst falls onto the slag discharge platform 43 fixedly connected to the bottom of the inner wall of the separator 2. Through the guiding action of the slag discharge platform 43, the magnetic catalyst moves to the discharge channel 44 penetrating the left side of the outer wall of the separator 2 and is finally discharged from the separator 2 through the discharge channel 44, thus realizing the collection of the magnetic catalyst.

[0052] The waste material separated in the separatory tank 2 is discharged through the waste pipe 373 of the solution transport pipe assembly 37. The waste pipe 373 penetrates the bottom of the front side of the outer wall of the separatory tank 2 and uses gravity to discharge the waste material.

[0053] When it is necessary to terminate the reaction or perform cleaning, loosen the engagement of the movable buckle 51 and the ring clamp 52 to separate the cover 31 from the mixing tank 1 for cleaning and maintenance of the equipment interior.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
