Description

Technical Field

[0001] The utility model mainly relates to the technical field of industrial naphthalene purification, and particularly relates to an industrial naphthalene purification device. Background Art

[0002] The purification methods of naphthalene mainly include crystallization method, hydrofining method and solvent method. During the production process using the crystallization method, the separation is carried out by utilizing the difference in the crystallization points between naphthalene and impurities. The crystallization point of naphthalene is 80.3 °C, while the crystallization point of some impurities such as benzothiophene is 31.3 °C. Such a temperature difference enables naphthalene to crystallize preferentially, while the impurities remain in a liquid state. Through multiple crystallization and melting processes, a new equilibrium can be established, thereby obtaining a high-purity naphthalene product.

[0003] The existing patent (Publication No.: CN207412789U) discloses a refined naphthalene crystallization tank. The outside of the tank body is sleeved with a cooling jacket. A circular opening in the form of a through-hole is provided on the top surface of the tank body. A circular side groove is provided on the side wall of the opening. At least two sliding pulleys are evenly distributed in the side groove. The sliding pulleys are connected to the side wall of a circular lower rotating plate inside the opening. A circular rotating rod opening in the form of a through-hole is provided at the center of the lower rotating plate. A cylindrical rotating rod extends into the rotating rod opening. The upper end of the rotating rod is located above the tank body. The upper end of the rotating rod is connected to an upper rotating plate. At least two support rods are evenly distributed and connected to the lower surface of the upper rotating plate. The lower ends of the support rods are respectively provided with upper pulleys. A circular upper groove is provided on the upper surface of the lower rotating plate corresponding to the upper pulleys. The sliding pulleys are all arranged in the upper groove; the lower end of the rotating rod is connected to a transverse plate-shaped stirring paddle. At least two corrugated convex structures are evenly distributed on the side edge of the stirring paddle; it is convenient to use, and the stirring and crystallization are uniform.

[0004] During the implementation of this solution by the inventor, it was found that some crystals adhered to components such as the stirring paddle, resulting in the situation that some naphthalene crystals could not be peeled off from the structural components in the crystallization tank during the naphthalene purification operation.

[0039] Referring to the attached Figures 1-5 drawings, the present utility model provides an industrial naphthalene purification device, including the following structures:

[0040] A crystallization tank 1, a discharge pipe 11 is fixedly provided at the bottom of the crystallization tank 1, a top cover 2 is movably clamped at the top of the crystallization tank 1, a feed pipe 21 is fixedly provided at the bottom of the top cover 2, a driving motor 3 is fixedly provided at the top of the top cover 2, and a flat gear 31 is fixedly provided at the bottom output end of the driving motor 3.

[0041] A rotating shaft 4, a conductive slip ring 5 is provided at the top of the rotating shaft 4, a guide rod 6 is fixedly provided at the bottom of the rotating shaft 4, a mounting seat 7 is fixedly provided at the bottom of the guide rod 6, a limiting spring 71 is fixedly provided at the top of the mounting seat 7, and a sliding seat 8 is fixedly connected to the top of the limiting spring 71.

[0042] In this embodiment, as Figure 3 and Figure 4 shown, the top of the rotating shaft 4 is movably connected to the middle of the top cover 2, a flat tooth ring 41 is clamped on the outer side of the top of the rotating shaft 4, and the outer side of the flat tooth ring 41 is meshed with the outer side of the flat gear 31.

[0043] The driving motor 3 and the flat gear 31 cooperate to drive the flat tooth ring 41 to rotate, completing the driving process of the rotating shaft 4. Among them, the rotating shaft 4 and the guide rod 6 cooperate to drive the mounting seat 7 and the limiting spring 71 to rotate. Among them, the cooperation of the guide groove 61 and the sliding pin 81 completes the rotation of the sliding seat 8 in cooperation with the guide rod 6.

[0044] In this embodiment, as Figure 2 , Figure 3 and Figure 5 show, a guide groove 61 is fixedly arranged on the outer side of the guide rod 6, and the middle part of the limiting spring 71 is movably sleeved on the outer side of the guide rod 6.

[0045] The limiting spring 71 fits on the outer side of the guide rod 6. During the opening and closing process of the electromagnet 72, the limiting spring 71 will stretch and contract on the outer side of the guide rod 6, wiping off the naphthalene crystals adhering to the outside of the guide rod 6. At the same time, during the deformation process of the limiting spring 71, the naphthalene crystals will fall off from the outside of the limiting spring 71.

[0046] In this embodiment, as Figure 2 and Figure 3 show, electromagnets 72 are fixedly arranged at both the front and rear ends of the mounting seat 7, and the electromagnets 72 are electrically connected to the conductive slip ring 5.

[0047] The electromagnet 72 and the conductive slip ring 5 cooperate to complete the power supply during the rotation process of the rotating shaft 4, the guide rod 6 and the mounting seat 7 driving the electromagnet 72 to rotate.

[0048] In this embodiment, as Figure 3 and Figure 5 show, a sliding pin 81 is fixedly arranged in the middle of the sliding seat 8, the outer side of the sliding pin 81 extends into the guide groove 61, and ball head seats 82 are fixedly arranged at both the front and rear ends of the sliding seat 8, and a deflection groove is fixedly arranged on the outer side of the ball head seat 82.

[0049] The ball head seat 82 is provided for the assembly of the telescopic rod 9. When the sliding seat 8 and the ball head seat 82 cooperate to drive the telescopic rod 9 to rotate, at this time, with the design of the counterweight seat 91 outside the telescopic rod 9, the telescopic rod 9 deflects upward in cooperation with the deflection groove during the rotation outside the sliding seat 8, and the outer side of the counterweight seat 91 will contact the inner wall of the crystallization box 1.

[0050] In this embodiment, as Figure 2 , Figure 3 and Figure 5 show, a telescopic rod 9 is movably connected to the middle of the ball head seat 82, a counterweight seat 91 is fixedly arranged on the outer side of the telescopic rod 9, the counterweight seat 91 cooperates with the electromagnet 72, the telescopic rod 9 is composed of sleeves at the front and rear ends and a conduit in the middle, and the front and rear ends of the inner wall of the telescopic rod 9 are respectively clamped with the front and rear ends of the return spring.

[0051] The structural design of the telescopic rod 9 facilitates the contact between the counterweight seat 91 and the telescopic rod 9 with the inner wall of the crystallization box 1 during the rotation of the sliding seat 8, avoiding the adhesion of naphthalene crystals to the inner wall of the crystallization box 1. Among them, after the electromagnet 72 is turned on, the limiting spring 71 contracts, and the sliding seat 8 moves towards the mounting seat 7 outside the guide rod 6.

[0052] During the sliding process of the sliding seat 8 towards the bottom of the guide rod 6, if the driving motor 3 continues to operate, the counterweight seat 91 will maintain contact with the inner wall of the crystallization tank 1 and wipe off the naphthalene crystals adhering to the surface of the inner wall of the crystallization tank 1. If the driving motor 3 stops, the counterweight seat 91 will be adsorbed outside the electromagnet 72. During the adsorption process, when the counterweight seat 91 comes into contact with the electromagnet 72, the naphthalene crystals adhering to the outside of the counterweight seat 91 and the telescopic rod 9 will oscillate and fall off.

[0053] The above-described embodiments merely represent certain implementation manners of the present utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
