Description
Technical Field
[0001] This utility model relates to the technical field of sodium sulfonate crystallization apparatus, and more particularly to a crystallization apparatus for the production of sodium isophthalic acid-5-sulfonate. Background Technology
[0002] Sodium sulfonate is a common surfactant widely used in detergents, emulsifiers, and wetting agents. Crystallization is a crucial step in its production. Crystallization equipment is used to separate and purify sodium sulfonate from solution to ensure the quality and purity of the final product.
[0003] Existing technologies, such as the utility model patent with publication number CN220257210U, disclose a recrystallization device. This patent employs a crystallization kettle, a recrystallization unit, and a tilting unit. A filter barrel is provided inside the crystallization kettle, with uniformly distributed through holes on its bottom surface. The recrystallization unit includes a vertical arm, a horizontal arm, a ring body, a rotating shaft, a stirring fan blade assembly, a motor mounting frame, and a stirring motor. The upper left and right sides of the filter barrel are fixedly connected to the bottom ends of the vertical arm, and the upper outer ends of the vertical arm are fixedly connected to both ends of the horizontal arm. A ring body is provided in the middle of the horizontal arm, and a rotating shaft is inserted inside the ring body. The bottom end of the rotating shaft is fixedly connected to the stirring fan blade assembly. Utilizing the dissolving properties, a saturated sodium benzenesulfinate solution is injected into the crystallization kettle, and the solution is heated and distilled, causing the sodium benzenesulfinate to recrystallize in the solution. Then, the sodium benzenesulfinate is obtained by lifting and tilting through the filter barrel, resulting in a significant improvement in efficiency.
[0004] The inventors discovered through daily use that crystallization in existing technologies is a process closely related to temperature and concentration, typically requiring precise temperature control. In traditional crystallization apparatus, simultaneous heating and cooling within a single process is impossible, necessitating staged processes. This increases process complexity and makes precise temperature gradient control difficult, impacting the crystallization efficiency and quality of sodium sulfonate. Sodium sulfonate crystallization usually requires lengthy heating and cooling processes. Traditional apparatus requires multiple temperature change stages to complete crystallization, which not only increases operation time but also reduces production efficiency.
[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a crystallization apparatus for the production of sodium isophthalic acid-5-sulfonate.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: It includes a base plate, an auxiliary structure, and two adjustment structures. A vertical rod is fixedly connected to the upper surface of the base plate. A tank is provided on one side of the vertical rod. The tank is connected to the vertical rod via the auxiliary structure. The auxiliary structure includes a rotating ring, which is rotatably connected to the vertical rod. A connecting frame is fixedly connected to the rotating ring's arc surface. The end of the connecting frame away from the rotating ring is fixedly connected to the tank. A servo motor is installed at the upper end of the vertical rod, and the output end of the servo motor is fixedly connected to...

The servo motor drives the turntable to rotate, the turntable moves the fixed rod, the fixed rod moves the rotating ring, the rotating ring moves the connecting frame, and the connecting frame moves the tank. The tank then moves to the heating base for heating and melting. After the raw material melts, the process continues. The servo motor is then started, and the tank is moved to the cooling base for cooling and crystallization.
[0009] Preferably, a plurality of the fan blades are evenly distributed on the drive shaft, and the fan blades are plastic blades.

[0011] Preferably, the cross-section of the fixing rod is "L" shaped, and the fixing rod is a stainless steel rod.
[0012] The effect achieved by the above components is that the stainless steel material can increase the service life of the fixing rod and prevent the fixing rod from rusting during use.
[0013] Preferably, the connecting frame is a titanium alloy frame, and the cross-section of the connecting frame is triangular.
[0014] Preferably, the base plate has adjustment structures on both sides, each adjustment structure including a connecting plate, the connecting plate being fixedly connected to the base plate, and a sleeve plate being fixedly connected to the upper surface of both the base plate and the connecting plate. A sliding plate is slidably connected to the inner wall of the sleeve plate, and two sets of sliding plates are fixedly connected to the heating seat and the cooling seat respectively. A plurality of insertion holes are opened on the inner wall of the sliding plate, and an insertion rod is slidably connected to the inner wall of the sliding plate. The insertion rod is slidably connected to the insertion hole.
[0015] The effect achieved by the above components is as follows: when it is necessary to adjust the height of the heating base and the cooling base, pull the plug rod to move it, separate the plug rod from the socket, and then pull the slide plate to move it. The slide plate moves the heating base and the cooling base. The slide plate slides on the inner wall of the sleeve plate. After moving to the appropriate position, pull the plug rod to move it, align the plug rod with the sleeve plate and the appropriate socket, and then insert the plug rod to fix it.

This increases process complexity and makes precise temperature gradient control difficult, thus affecting the crystallization efficiency and quality of sodium sulfonate. Sodium sulfonate crystallization usually requires a lengthy heating and cooling process. Traditional apparatus requires multiple temperature change stages to complete crystallization, increasing operation time and reducing production efficiency. This new apparatus allows for convenient heating and cooling of sodium sulfonate within a single process, eliminating the need to move the sodium sulfonate solution to a fixed location for cooling.
[0022] In this invention, the height of the cooling seat and the heating seat can be quickly and easily adjusted by adjusting the adjustment structure, which can meet the needs of various tank models. Attached Figure Description
