Description

Technical Field

[0001] This utility model relates to the field of solvent removal technology, and in particular to a continuous multi-stage condensation device. Background Technology

[0002] In the chemical industry, solvent removal refers to the process by which a new phase (solid solution, pure component, or chemical substance) precipitates from a supersaturated solution or solid solution, reducing the supersaturation of the parent compound. In a supersaturated solid solution, the phenomenon of solute atoms segregating and precipitating a new phase is called solvent removal.

[0003] During solvent removal processing, a solvent removal vessel is required. In conventional reaction vessel solvent removal, the solvent is condensed and collected in a receiving tank. However, this type of device is not suitable for products that are prone to sublimation. As a result, the product will be evaporated during the solvent removal process, and the product will precipitate out when passing through the condenser, clogging the equipment.

[0004] To ensure effective desolvation in the easy-to-sublimate project, improvements to the existing structure are necessary. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of poor desolvation effect in the prior art and provides a continuous multi-stage condensation device with good desolvation effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a continuous multi-stage condensation device, comprising: a solvent extraction vessel, a transfer vessel, and a vacuum vessel, wherein the solvent extraction vessel, the transfer vessel, and the vacuum vessel are connected sequentially through pipelines;

[0007] The desolventizing vessel is connected to a feed pipe for feeding materials, and a horizontally retractable stirring rod is installed inside the desolventizing vessel.

[0008] The transfer vessel is equipped with a condenser rack.

[0009] The vacuum vessel is connected to an external vacuum pump.

[0010] This condensation device includes a solvent removal vessel, a transfer vessel, and a vacuum vessel, which are connected sequentially by pipelines, with the ends of the pipelines leading to the transfer vessel and vacuum vessel near the bottom. The solvent removal vessel has a feed pipe connected to its upper end, allowing the raw material to be removed to be added. Inside the solvent removal vessel is a stirring rod that agitates the raw material, improving the removal efficiency. The stirring rod is also horizontally extendable, increasing the agitation area and further enhancing the removal effect. A condenser rack is installed inside the transfer vessel to facilitate the condensation of any product mixed with the solvent, thus improving the removal efficiency. The vacuum vessel reduces the internal pressure of the condensation device, lowering the boiling point of the solvent, accelerating evaporation and removal, and further improving the removal effect.

[0011] Preferably, the desolventizing vessel, the transfer vessel, and the vacuum vessel are all fitted with desolventizing jackets. The desolventizing jacket of the desolventizing vessel is filled with a heating medium, and the desolventizing jackets of the transfer vessel and the vacuum vessel are filled with a cooling medium. The desolventizing vessel, transfer vessel, and vacuum vessel are all fitted with desolventizing jackets on their outer sides. A heating medium is added to the desolventizing jacket installed on the outside of the desolventizing vessel via a circulating filling machine, ensuring a constant temperature within the desolventizing vessel and thus improving the desolventizing effect. Simultaneously, a cooling medium is added to the desolventizing jackets installed on the outside of the transfer vessel and vacuum vessel via a circulating filling machine. The desolventizing jacket outside the transfer vessel lowers the temperature of the transfer vessel, allowing the solvent to mix with the product, condense, and be collected in the transfer vessel, improving the desolventizing effect. Simultaneously, the desolventizing jacket outside the vacuum vessel lowers the temperature of the vacuum vessel, reducing the internal pressure of the transfer vessel and desolventizing vessel, thereby lowering the boiling point of the solvent, increasing evaporation efficiency, and improving the desolventizing effect.

[0012] Preferably, a rotary motor is installed on the top of the desolvation vessel, and a connecting rod is installed inside the vessel. The connecting rod is connected to the rotary motor, and its lower end is connected to a stirring rod. Specifically, the rotary motor is installed on the top of the desolvation vessel, with its rotating end installed inside. The connecting rod inside the vessel is connected to the rotating end of the motor, and its lower end is connected to the stirring rod. The rotation of the rotary motor drives the stirring rod to rotate, thus stirring the solution to be desolvated, thereby improving evaporation efficiency and desolvation effect.

[0013] Preferably, the stirring rod is provided with a horizontal rod, which is connected to the lower end of the connecting rod. A sleeve is provided at the end of the connecting rod, and the sleeve is slidably fitted onto the connecting rod. Several stirring blades are provided on the outer wall of the sleeve. Specifically, the stirring rod includes a horizontal rod connected to the lower end of the connecting rod, and a sleeve is provided at the end of the connecting rod, which is fitted onto the connecting rod, allowing relative sliding between the sleeve and the connecting rod. Several stirring blades are evenly spaced on the outer wall of the sleeve. Rotation of the connecting rod drives the stirring blades to rotate, thereby stirring the solution, improving evaporation efficiency, and enhancing the solvent removal effect.

[0014] Preferably, a limiting piece is provided at the end of the horizontal rod, and a stop is provided at the open end of the sleeve, with the limiting piece cooperating with the stop. Specifically, the limiting piece at the end of the horizontal rod and the stop at the open end of the sleeve restrict the movement of the sleeve by blocking the stop. The rotation of the connecting rod allows the sleeve fitted onto the horizontal rod to move outward under centrifugal force. Furthermore, the rotating motor is a speed-controllable motor; different speeds control the extension length of the sleeve, thereby enabling the stirring plate to stir the solution at different locations, improving evaporation efficiency and thus enhancing the solvent removal effect.

[0015] Preferably, a guide rod is provided inside the sleeve, and a guide groove is provided on the end face of the horizontal rod, with the guide rod inserted into the guide groove. This structure, with the guide rod inside the sleeve and the guide groove on the end face of the horizontal rod, provides guidance, ensuring stable horizontal movement of the sleeve, preventing shaking, improving stirring effect, and consequently improving evaporation and solvent removal efficiency.

[0016] Preferably, the guide rod is fitted with a spring, one end of which is connected to the bottom surface of the sleeve, and the other end is connected to the end face of the horizontal rod. This structure allows the sleeve to be pulled back after moving outwards along the horizontal rod, and the position of the sleeve can be changed by varying the rotation speed of the motor. This allows for adjustments to the stirring effect, improves evaporation, and further enhances the solvent removal effect.

[0017] Preferably, the condenser rack includes an upright post and several condensing plates mounted on the upright post. The condensing plates are arranged at an angle downwards, and a vibrator is installed at the bottom of the upright post. The upright post is installed inside the condenser rack, and several condensing plates are mounted on the upright post. The condensing plates are used to condense the product mixed in the solvent during desolventizing upon contact with the condensing plates, collecting it in a transfer vessel and improving the desolventizing effect. The vibrator installed at the bottom of the upright post vibrates to cause the condensed product to fall from the condensing plates, facilitating collection and recovery.

[0018] The beneficial effects of this utility model are as follows: The rear end of the desolventizing kettle is connected to a transfer kettle and a vacuum kettle via pipelines. The transfer kettle can condense and collect the product mixed in the desolventizing solvent. At the same time, the vacuum kettle reduces the internal pressure of the condensation device, thereby lowering the boiling point of the solvent, accelerating evaporation and desolventizing, and thus improving the desolventizing effect. By rotating the motor at different speeds, the sleeve can be moved outward by centrifugal force. With the help of springs, the sleeve can achieve reciprocating motion, which can improve the stirring effect and simultaneously improve the evaporation and desolventizing effects.

[0025] Example 1, such as Figure 1-2 As shown, a continuous multi-stage condensation device includes: a desolvation vessel 1, a transfer vessel 2, and a vacuum vessel 3, which are connected sequentially by pipelines; the desolvation vessel 1 is connected to a feed pipe 4 for feeding materials, and a horizontally retractable stirring rod 5 is installed inside the desolvation vessel 1; a condenser rack 6 is installed inside the transfer vessel 2; and a vacuum pump is connected to the vacuum vessel 3.

[0026] The outer sides of the desolventizing vessel 1, the transfer vessel 2, and the vacuum vessel 3 are all fitted with desolventizing jackets 8. The desolventizing jacket 8 of the desolventizing vessel 1 is filled with a heating medium 9, and the desolventizing jackets 8 of the transfer vessel 2 and the vacuum vessel 3 are filled with a cooling medium 10 for condensation.

[0027] A rotating motor 11 is installed on the top of the desolventizing vessel 1. A connecting rod 12 is installed inside the desolventizing vessel 1. The connecting rod 12 is connected to the rotating motor 11. The lower end of the connecting rod 12 is connected to the stirring rod 5.

[0028] The stirring rod 5 is provided with a horizontal rod 50, which is connected to the lower end of the connecting rod 12. The end of the connecting rod 12 is provided with a sleeve 51, which is slidably sleeved with the connecting rod 12. A plurality of stirring blades 52 are provided on the outer wall of the sleeve 51.

[0029] The end of the horizontal bar 50 is provided with a limiting piece 53, and the open end of the sleeve 51 is provided with a stop block 54. The limiting piece 53 and the stop block 54 cooperate with each other.

[0030] The sleeve 51 is provided with a guide rod 55, and the end face of the horizontal rod 50 is provided with a guide groove 56, and the guide rod 55 is inserted into the guide groove 56.

[0031] A spring 57 is sleeved on the guide rod 55. One end of the spring 57 is connected to the bottom surface of the sleeve 51, and the other end is connected to the end face of the horizontal rod 50.

[0032] The condenser rack 6 includes a pole 60 and a plurality of condenser plates 61 mounted on the pole 60. The condenser plates 61 are arranged at an angle downwards, and a vibrator 62 is installed at the bottom of the pole 60.

[0033] The working principle of this utility model is as follows: Figure 1-2As shown, this condensation device includes a solvent stripping vessel 1, a transfer vessel 2, and a vacuum vessel 3. These three vessels are connected sequentially by pipelines, with the ends of the pipelines leading to the transfer vessel 2 and the vacuum vessel 3 located near the bottom. A feed pipe 4 is connected to the upper end of the solvent stripping vessel 1, allowing the raw material to be stripped to be added into it. A stirring rod 5 is installed inside the solvent stripping vessel 1. The rotation of the stirring rod 5 agitates the raw material, improving the stripping effect. The stirring rod 5 can also extend and retract horizontally, increasing the agitation area and further enhancing the stripping effect. A condenser rack 6 is installed inside the transfer vessel 2. This rack improves the condensation of the product mixed in the solvent within the transfer vessel 2, thus improving the stripping effect. The vacuum vessel 3 reduces the internal pressure of the condensation device, lowering the boiling point of the solvent, accelerating evaporation and stripping, and further improving the stripping effect.

[0034] The desolventizing vessel 1, the transfer vessel 2, and the vacuum vessel 3 are all fitted with desolventizing jackets 8 on their outer sides. A heating medium 9 is added to the desolventizing jacket 8 installed on the outside of the desolventizing vessel 1 via a circulating filling machine, ensuring a constant temperature within the desolventizing vessel 1 and thus improving the desolventizing effect. Simultaneously, a cooling medium 10 is added to the desolventizing jackets 8 installed on the outside of the transfer vessel 2 and the vacuum vessel 3 via a circulating filling machine. The desolventizing jacket 8 on the outside of the transfer vessel 2 lowers the temperature of the transfer vessel 2, allowing the product to mix into the solvent, condense, and be collected in the transfer vessel 2, improving the desolventizing effect. Simultaneously, the desolventizing jacket 8 on the outside of the vacuum vessel 3 lowers the temperature of the vacuum vessel 3, reducing the internal pressure of the transfer vessel 2 and the desolventizing vessel 1, thereby lowering the boiling point of the solvent, increasing evaporation efficiency, and improving the desolventizing effect.

[0035] A rotary motor 11 is installed on the top of the desolvation vessel 1. The rotating end of the rotary motor 11 is installed inside the desolvation vessel 1. A connecting rod 12 inside the desolvation vessel 1 is connected to the rotating end of the rotary motor 11. The lower end of the connecting rod 12 is connected to the stirring rod 5. The rotation of the rotary motor 11 can drive the stirring rod 5 to rotate, thereby stirring the solution to be desolvated, which can improve the evaporation efficiency and the desolvation effect.

[0036] The stirring rod 5 includes a horizontal rod 50 connected to the lower end of the connecting rod 12. A sleeve 51 is fitted onto the end of the connecting rod 12, allowing relative sliding between the sleeve 51 and the connecting rod 12. Several stirring blades 52 are evenly spaced on the outer wall of the sleeve 51. Rotation of the connecting rod 12 drives the stirring blades 52 to rotate, thus stirring the solution, improving evaporation efficiency, and enhancing the solvent removal effect.

[0037] A limiting piece 53 is provided at the end of the horizontal rod 50, and a stop block 54 is provided at the open end of the sleeve 51. The limiting piece 53 can block the stop block 54, thereby restricting the movement of the sleeve 51. The rotation of the connecting rod 12 allows the sleeve 51 sleeved on the horizontal rod 50 to move outward under the action of centrifugal force. At the same time, the rotating motor 11 is a motor with controllable speed. By changing the speed, the extension length of the sleeve 51 can be controlled, thereby enabling the stirring plate 52 to stir the solution at different positions, improving the evaporation efficiency and thus improving the desolvation effect.

[0038] The sleeve 51 is equipped with a guide rod 55 inside and a guide groove 56 is provided on the end face of the horizontal rod 50. The guide rod 55 is inserted into the guide groove 56. This structure can achieve a guiding function, so that the horizontal movement of the sleeve 51 is stable, avoiding shaking, improving the stirring effect, and thus improving the evaporation effect and the desolvation effect.

[0039] A spring 57 is fitted onto the guide rod 55. One end of the spring 57 is connected to the bottom surface of the sleeve 51, and the other end is connected to the horizontal rod 50. This structure ensures that when the sleeve 51 moves along the horizontal rod 50, the spring 57 can pull the sleeve 51 back after it moves outward. In conjunction with the change in the rotation speed of the rotating motor 11, the position of the sleeve 51 can be changed, thereby adjusting the stirring effect and improving the evaporation effect, further enhancing the desolvation effect.

[0040] The condenser rack 6 has an internal support rod 60 with several condensing plates 61 mounted on it. The condensing plates 61 are used to condense the product mixed in the solvent during desolventizing, and collect it in the transfer vessel 2, thereby improving the desolventizing effect. The vibrator 62 installed at the bottom of the support rod 60 can vibrate to make the condensed product fall off the condensing plates 61 for easy collection and recycling.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
