[0001] This utility model relates to the field of diphenylamine production technology, and in particular to an automatic impurity separation device for chemical reaction filtration. Background Technology

[0002] In the chemical production field, diphenylamine, as an important organic chemical, is widely used in dyes, explosives, pharmaceuticals, and many other industries. Its production process involves complex chemical reactions and material transformations. During diphenylamine production, various impurities that need to be separated are generated due to factors such as the reactants, reaction mechanisms, and subsequent processing techniques. Chinese utility model patent, authorized publication number "CN222427977U", discloses a device for continuous diphenylamine production, including a heat-insulating tank. A stirring tank is fixedly connected to the upper surface of the heat-insulating tank. A cover plate is sealed to the upper surface of the stirring tank. A rotating shaft is rotatably connected to the lower surface of the cover plate. A stirring rod is fixedly connected to the surface of the rotating shaft. A first feeding pipe and a second feeding pipe are sealed to the upper surface of the cover plate. A heating sleeve is fixedly connected inside the heat-insulating tank, and a heating wire is fixedly connected inside the heating sleeve.

[0003] The above technical solution controls the rate at which the mixed raw materials flow into the insulated tank through a second solenoid valve. Simultaneously, the heating wire can be activated to heat the raw materials, and the operator can adjust the heating temperature. During heating, the raw materials can be filtered through a filter screen to remove impurities and reduce the impurity content. However, the above technical solution still has certain drawbacks. Since the mixing tank is fixed inside the insulated tank, it is not convenient to clean the impurities on the surface of the filter screen when filtering diphenylamine during production, which can easily cause filter screen blockage. Frequent shutdowns are required to clean the filter screen, which seriously affects production efficiency. Therefore, this utility model proposes a new solution. Utility Model Content

This device can solve the problem that, since the mixing tank is fixed inside the insulated tank, it is not convenient to clean the impurities on the surface of the filter screen when filtering diphenylamine during production, which easily causes the filter screen to become clogged and requires frequent shutdowns to clean the filter screen, seriously affecting production efficiency.

[0028] Please see Figure 1-6 This utility model provides a technical solution: an automatic impurity separation device for chemical reaction filtration, including a filter tank 1 and a filter assembly. The filter assembly is mounted on the filter tank 1 and includes a fixed bracket 2, which is fixedly connected to the upper end of the filter tank 1. A hydraulic rod 5 is fixedly connected inside the fixed bracket 2, and a mounting plate 6 is fixedly connected to the output end of the hydraulic rod 5. Two guide rods 7 are fixedly connected to the upper end of the mounting plate 6, and both guide rods 7 are slidably connected to the fixed bracket 2. A first connecting shaft 10 is rotatably connected to the lower end of the mounting plate 6, and a drive motor 8 is fixedly connected to the lower end of the mounting plate 6. The output end of the drive motor 8 is fixedly connected to... A gear 9 is connected to the filter. A gear ring 11 is fixedly connected to the surface of the first connecting shaft 10. The filter tank 1 is sleeved on the surface of the first connecting shaft 10. A filter cylinder frame 12 is fixedly connected inside the filter tank 1. A filter cylinder 13 is rotatably connected to the upper end of the filter cylinder frame 12. A movable disk 15 is slidably connected inside the filter cylinder 13. The movable disk 15 is fixedly connected to the first connecting shaft 10. Multiple sliding grooves 16 are opened on the side of the movable disk 15. Multiple first connecting strips 17 are fixedly connected to the inner wall of the filter cylinder 13. The multiple first connecting strips 17 are slidably connected to the corresponding sliding grooves 16. Multiple first guide vanes 14 are fixedly connected to the outer surface of the filter cylinder 13.

[0029] Multiple limiting plates 20 are fixedly connected to the upper end of the filter cylinder 13, and the multiple limiting plates 20 are respectively set on the upper end of the corresponding first connecting strip 17.

[0030] The upper end of the movable plate 15 is conical, and multiple second connecting strips 21 are fixedly connected to the upper surface of the movable plate 15.

[0031] The lower end of the filter cylinder 13 is fixedly connected to a second connecting shaft 18, and a second guide vane 19 is fixedly connected to the surface of the second connecting shaft 18. The second guide vane 19 is in a spiral shape with a larger upper part and a smaller lower part.

[0032] The upper end of the filter tank 1 is fixedly connected to the feed pipe 3, which extends into the interior of the filter tank 1. The lower end of the feed pipe 3 is arc-shaped.

[0033] The lower end of the filter tank 1 is conical, and a discharge pipe 4 is fixedly connected to the lower end of the filter tank 1.

[0034] When using this device, the diphenylamine reaction liquid to be filtered (containing solid impurities, such as by-product crystals, catalyst residues, etc.) enters the filter tank 1 through the feed pipe 3. The lower end of the feed pipe 3 has an arc-shaped structure, which can guide the reaction liquid to flow in the tangential direction along the inner wall of the filter tank 1, avoiding direct impact on the filter components. At the same time, when the liquid flows in, it comes into contact with the first guide vane 14 on the outside of the filter cylinder 13, forming a spiral circulation in the filter tank 1. The centrifugal force is used to initially achieve solid-liquid pre-separation - the liquid flows to the outside, and the solid impurities gather towards the center of the filter cylinder 13 due to gravity and centrifugal force, laying the foundation for subsequent filtration.

[0035] The reaction liquid flows to the filter cylinder 13 under the action of circulation; the liquid components permeate to the outside through the filter holes of the filter cylinder 13 and enter the cavity between the filter tank 1 and the filter cylinder 13. Then, they converge along the conical inner wall at the lower end of the filter tank 1 and are finally discharged through the discharge pipe 4, which is the filtered clean diphenylamine solution. Solid impurities are trapped inside the filter cylinder 13 and gradually accumulate on the cylinder wall as the reaction liquid continues to flow in.

[0036] To prevent impurities from clogging the filter holes, the device drives the filter cylinder 13 to rotate via the drive motor 8: the output end of the drive motor 8 drives the gear 9 to rotate, the gear 9 meshes with the gear ring 11 on the surface of the first connecting shaft 10, thereby driving the first connecting shaft 10 to rotate; the first connecting shaft 10 and the filter cylinder 13 are linked through the sliding groove 16 of the movable disk 15 and the first connecting strip 17 on the inner wall of the filter cylinder 13, ultimately driving the filter cylinder 13 to rotate around its own axis.

[0037] When the filter cartridge 13 rotates, the first guide vane 14 on the outside enhances the liquid circulation intensity inside the tank and improves the filtration efficiency; at the same time, the centrifugal force generated by the rotation makes the internal impurities evenly distributed on the cylinder wall, avoiding local accumulation that could cause filter pore blockage.

[0038] When impurities accumulate to a certain extent on the inner wall of the filter cartridge 13, the movable disc 15 is automatically cleaned by the hydraulic rod 5.

[0039] The hydraulic rod 5 pushes the mounting plate 6 to move up and down along the guide rod 7 (the guide rod 7 ensures the stability of the movement), which drives the first connecting shaft 10 and the movable plate 15 fixedly connected to it to move up and down synchronously.

[0040] The sliding groove 16 on the side of the movable disc 15 slides in conjunction with the first connecting strip 17 on the inner wall of the filter cylinder 13, ensuring that the movable disc 15 can move axially while rotating synchronously with the filter cylinder 13.

[0041] During the up-and-down movement of the movable disc 15, the side of the movable disc 15 contacts the inner wall of the filter cylinder 13, scraping away impurities on the cylinder wall.

[0042] Since the upper end of the movable disc 15 is conical, and with the use of the second connecting strip 21, it is easy to drive the impurities on the surface of the movable disc 15 to rotate synchronously with the movable disc 15. Under the centrifugal force, it is easy to move the impurities on the surface of the movable disc 15 to the edge of the movable disc 15. When the movable disc moves to the upper end of the filter cylinder 13, it throws the impurities to the inner wall of the filter tank 1, and scrapes them with the first guide vane 14, conveying the impurities to the bottom of the filter tank 1, and finally discharges them from the discharge pipe 4.

[0043] The limiting plate 20 at the upper end of the filter cylinder 13 can limit the upward movement of the movable disc 15 and prevent it from detaching from the filter cylinder 13.

[0044] Furthermore, by driving the movable disc 15 up and down through the hydraulic rod 5, and cooperating with the contact and scraping between the side of the movable disc 15 and the inner wall of the filter cylinder 13, the impurities accumulated on the inner wall of the filter cylinder 13 can be directly removed without stopping the machine; then the impurities are transported to the bottom through the first guide vane 14 and finally discharged through the discharge pipe 4; this solves the drawback of traditional filter screens requiring machine shutdown for cleaning, improves the continuous operation capability of diphenylamine production, and improves the filtration efficiency of diphenylamine.

[0045] The drive motor 8 drives the gear 9 to rotate, which is linked to the first connecting shaft 10 via the gear ring 11, driving the filter cylinder 13 to rotate. On the one hand, the first guide vane 14 on the outside of the filter cylinder 13 enhances the spiral circulation inside the tank and accelerates the liquid permeation speed. On the other hand, the centrifugal force generated by the rotation of the filter cylinder 13 makes the impurities evenly distributed on the inner wall of the filter cylinder 13, avoiding local accumulation and clogging of the filter holes. Under the dual effect, the filtration efficiency and stability of the diphenylamine reaction solution are greatly improved.
