[0034] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installing", "connecting", "linking", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.
[0035] The following is for reference. Figures 1 to 4 Describes a devolatilizer according to an embodiment of the present invention.
[0036] refer to Figures 1 to 4 As shown, a devolatilizer according to an embodiment of the present utility model includes a vessel body 100, a spray component 200, a drive component 300, a stirring module 400, and a heating jacket 500.
[0037] The spray component 200 is installed on the inner side of the upper end of the vessel body 100. The spray component 200 is adapted to communicate with the outside. The drive component 300 is installed on the top of the vessel body 100. The drive end of the drive component 300 extends into the interior of the vessel body 100 and extends below the spray component 200. The stirring module 400 includes a stirring shaft 410 installed on the drive end of the drive component 300. The tail end of the stirring shaft 410 is movably connected to the bottom of the vessel body 100. A spirally wound ribbon assembly 420 and a first stirring blade assembly 430 are installed on the stirring shaft 410. The first stirring blade assembly 430 is located inside the ribbon assembly 420. The rotational pushing direction of the first stirring blade assembly 430 is opposite to the rotational pushing direction of the ribbon assembly 420. The heating jacket 500 is disposed on the outer side of the vessel body 100.
[0038] Before using the devolatilizer, a certain amount of reactant is injected into the vessel 100. When it starts running, the heating jacket 500 heats the vessel 100, and the spray component 200 receives the reaction product from the outside and sprays it evenly into the interior of the vessel 100. The drive component 300 starts to rotate clockwise at the same time, driving the screw ribbon assembly 420 and the first stirring blade assembly 430 on the stirring shaft 410. The screw ribbon assembly 420 pushes the product upward to form a vortex agitation while rotating clockwise, and the first stirring blade assembly 430 pushes the product downward to form a vortex agitation while rotating clockwise, so that the product is more evenly agitated by collision.
[0039] It is understandable that the tail end of the stirring shaft 410 is often connected to the bottom of the vessel body 100 by a bearing connection, which can stabilize the stirring shaft 410 and reduce the centrifugal vibration generated by the stirring shaft 410 when it rotates.
[0040] Understandably, the vessel body 100 is also equipped with four connecting lugs 110 to facilitate the installation of the devolatilizer.
[0041] In some specific embodiments of this utility model, the spraying component 200 includes a spraying part 210 and a feeding part 220 that communicate with each other. The spraying part 210 is located inside the vessel body 100, and the feeding part 220 penetrates the outer wall of the vessel body 100. The spraying part 210 has a plurality of spraying slots 211 facing the bottom of the vessel body 100, and the feeding part 220 has a feeding port 221.
[0042] refer to Figure 1 As shown, in this embodiment, the spraying component 200 has a columnar structure and is horizontally mounted on the vessel body 100. The spraying part 210 located inside the vessel body 100 has a plurality of spraying slots 211 arranged in sequence, which allows the product input from the feed inlet 221 of the feed part 220 located outside the vessel body 100 to be evenly scattered into the interior of the vessel body 100, so that the reaction can be more complete.
[0043] In some specific embodiments of this utility model, the first stirring blade assembly 430 includes a first stirring blade 431 and a second stirring blade 432 connected to each other. The first stirring blade 431 and the second stirring blade 432 are mounted on the stirring shaft 410. The first stirring blade 431 is set at an angle to the horizontal plane, and the extension surface of the first stirring blade 431 and the extension surface of the second stirring blade 432 form a cross-shaped structure.
[0044] refer to Figure 1 , Figure 2 and Figure 3 As shown, the first stirring blade 431 and the second stirring blade 432 are connected around the stirring shaft 410. The extension surface of the first stirring blade 431 and the extension surface of the second stirring blade 432 are arranged perpendicularly. The first stirring blade 431 forms a 45° angle with the horizontal plane.
[0045] Understandably, when the first stirring blade 431 and the second stirring blade 432 rotate clockwise via the stirring shaft 410, the pushing direction of both the first stirring blade 431 and the second stirring blade 432 is downward. Understandably, the angle between the first stirring blade 431 and the horizontal plane is between 30° and 60°, with 45° being the optimal stirring effect.
[0046] In some specific embodiments of this utility model, a second stirring blade assembly 440 is further included. The second stirring blade assembly 440 is located below the first stirring blade assembly 430. The first stirring blade assembly 430 and the second stirring blade assembly 440 are arranged at an angle relative to each other on the horizontal plane. The second stirring blade assembly 440 and the first stirring blade assembly 430 have the same structure. The first stirring blade assembly 430 and the second stirring blade assembly 440 are arranged perpendicularly relative to each other on the horizontal plane.
[0047] refer to Figure 1 , Figure 2 and Figure 3 As shown, the second stirring blade assembly 440 enables the mixing of upper and lower layers, resulting in more uniform mixing. The first stirring blade assembly 430 and the second stirring blade assembly 440 are perpendicular to each other on a relatively horizontal plane, further achieving uniform mixing.
[0048] In some specific embodiments of this utility model, the bottom of the vessel body 100 is a conical structure. The spiral ribbon assembly 420 includes a first connecting shaft 421 horizontally passing through the upper end of the stirring shaft 410, and a first spiral ribbon 422 and a second spiral ribbon 423 respectively connected to the two ends of the first connecting shaft 421 and having opposite spiral directions. The first spiral ribbon 422 and the second spiral ribbon 423 spirally surround the periphery of the stirring shaft 410. The bottom of the first spiral ribbon 422 and the second spiral ribbon 423 are connected to the stirring shaft 410. The first stirring blade assembly 430 is located below the first connecting shaft 421. The first spiral ribbon 422 passes through the extension surface of the first stirring blade 431 at an angle, and the second spiral ribbon 423 passes through the extension surface of the second stirring blade 432 at an angle.
[0049] refer to Figure 1 , Figure 2 and Figure 3 As shown, the first spiral ribbon 422 and the second spiral ribbon 423 have opposite spiral directions. When the stirring shaft 410 rotates, they can generate forces in the same direction on the stirred product. The first connecting shaft 421 not only connects the first spiral ribbon 422 and the second spiral ribbon 423, but also plays a certain role in stirring. The structure of the first spiral ribbon 422 passing through the extension surface of the first stirring blade 431 at an angle allows the first spiral ribbon 422 and the first stirring blade 431 to cooperate and generate forces in the same opposite directions. Similarly, the structure of the second spiral ribbon 423 passing through the extension surface of the second stirring blade 432 at an angle allows the second spiral ribbon 423 and the second stirring blade 432 to cooperate and generate forces in the same opposite directions, making the stirring more uniform.
[0050] In some specific embodiments of this utility model, the ribbon assembly 420 further includes a second connecting shaft 424, which is located below the first connecting shaft 421. The second connecting shaft 424 is mounted on the stirring shaft 410, with one end of the second connecting shaft 424 connected to the first ribbon 422 and the other end of the second connecting shaft 424 connected to the second ribbon 423.
[0051] refer to Figure 1 and Figure 2 As shown, the second connecting shaft 424 can make the connection between the first screw ribbon 422 and the second screw ribbon 423 more secure, and the second connecting shaft 424 also has a certain stirring function. It can be understood that the screw ribbon assembly 420 can also be equipped with more connecting shafts as needed to securely connect the first screw ribbon 422 and the second screw ribbon 423.
[0052] In some specific embodiments of this utility model, the first connecting shaft 421, the first stirring blade assembly 430, the second connecting shaft 424 and the second stirring blade assembly 440 are arranged at equal intervals on the stirring shaft 410, and the blade length of the second stirring blade assembly 440 is less than the blade length of the first stirring blade assembly 430.
[0053] refer to Figure 1 and Figure 2 As shown, the first connecting shaft 421, the first stirring blade assembly 430, the second connecting shaft 424 and the second stirring blade assembly 440 are arranged evenly on the stirring shaft 410 in sequence to ensure that the stirring force received at all parts of the vessel body 100 is similar, so that the stirring is more uniform.
[0054] It is understandable that the length of the second connecting shaft 424 is the same as that of the first connecting shaft 421. The length of the second connecting shaft 424 is also affected by the shape and structure of the vessel body 100. When the lower end of the vessel body 100 is long, the length of the second connecting shaft 424 can be shorter than that of the first connecting shaft 421, so that the bottom can also be stirred and propelled.
[0055] In some specific embodiments of this utility model, a heating jacket 500 is also included. The heating jacket 500 has a cavity 510 inside. The cavity 510 has a liquid inlet 520, a liquid outlet 530, a temperature measuring port 540 and a pressure measuring port 550. The liquid inlet 520 and the temperature measuring port 540 are close to the bottom of the heating jacket 500, and the liquid outlet 530 and the pressure measuring port 550 are close to the top of the heating jacket 500.
[0056] refer to Figure 1As shown, heat transfer oil is introduced into the cavity 510 from bottom to top through the liquid inlet 520 at the lower end, which can evenly heat the vessel body 100 from the outside and discharge it from the liquid outlet 530, forming a continuous circulation to ensure the stability of the outside temperature. A temperature measuring port 540 is provided to measure the temperature in real time, and a pressure measuring port 550 is provided to test and ensure the pressure value inside the cavity 510.
[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
