[0024] The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention.

They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0026] The present embodiment provides a crystallization and purification device for the production of triallyl isocyanurate, which uses a centrifugal method to perform crystallization and purification treatment on triallyl isocyanurate, thereby simplifying the configuration of the equipment and effectively reducing the crystallization and purification treatment cost of triallyl isocyanurate.

[0027] Combination Figure 1 and Figure 2 As shown, the crystallization device of this embodiment includes an outer cylinder 10 and a crystallization assembly 20 located in the outer cylinder 10. The outer cylinder 10 is used to contain the treatment liquid, and the crystallization assembly 20 can perform centrifugal crystallization purification treatment on triallyl isocyanurate.

[0028] In this embodiment, a mounting bracket 11 is provided on the top of the outer cylinder 10 to seal the top of the outer cylinder 10. The outer cylinder 10 is filled with a treatment liquid. A liquid level gauge 40 is provided on the mounting bracket 11. The bottom end of the liquid level gauge 40 is located in the outer cylinder 10 to monitor the liquid level in the outer cylinder 10. When there is too much treatment liquid in the outer cylinder 10, the treatment liquid can be discharged in an appropriate amount to ensure the smooth progress of the subsequent crystallization operation. The mounting bracket 11 used in this embodiment is a channel steel bracket.

[0029] Specifically, the liquid level meter 40 used in this embodiment is a connecting rod type float liquid level meter 40 , and the top end of the liquid level meter 40 is fixed on the mounting bracket 11 .

[0030] Combination Figure 2 and Figure 3As shown, the crystallization component 20 in this embodiment includes a driver 21, an inner cylinder 22 located at the driving end of the driver 21, and a filter bag 23 located in the inner cylinder 22. The inner cylinder 22 is located in the outer cylinder 10, and a filter hole 221 is provided on the surface of the inner cylinder 22. A reflux pipe 30 is provided on the inner cylinder 22, and the reflux pipe 30 is connected to the inside of the inner cylinder 22. The filter bag 23 is open and attached to the inner wall of the inner cylinder 22. The liquid to be treated in this embodiment enters the inner cylinder 22 through the reflux pipe 30, and the inner cylinder 22 is driven by the driver 21 to rotate at a high speed. Under the centrifugal action, triallyl isocyanurate can be crystallized in the filter bag 23, so as to realize the centrifugal crystallization and purification treatment of triallyl isocyanurate. The opening of the filter bag 23 in this embodiment adopts an open structure design, which can maximize the air drying treatment of the crystallization of triallyl isocyanurate and increase the crystallization amount of triallyl isocyanurate.

[0031] Specifically, in this embodiment, the pore size of the filter hole 221 is 0.2mm-0.4mm, and the mesh size of the filter bag 23 is 500 mesh, 600 mesh or 800 mesh. The filter bags 23 of the above three mesh sizes can effectively intercept triallyl isocyanurate and increase the number of crystals of triallyl isocyanurate.

[0032] In this embodiment, a connecting port 50 is provided at the bottom of the outer cylinder 10, and the connecting port 50 is connected to an external water pump. When there is too much processing liquid in the outer cylinder 10, the processing liquid in the outer cylinder 10 is discharged through the connecting port 50, which is conducive to the smooth progress of the crystallization operation.

[0033] Furthermore, in this embodiment, the driver 21 is a driving motor, which is provided with a matching reducer. The rotation speed of the driving motor is 3000 rpm, which becomes 120 rpm after being decelerated by the reducer. The reducer provides power support for the inner cylinder 22, enabling it to perform centrifugal crystallization operation on the treated liquid at a rotation speed of 1200 per minute.

[0034] In actual use of the crystallization device of this embodiment, the liquid to be treated containing triallyl isocyanurate is introduced into the inner cylinder 22 through the reflux pipe 30, and the driver 21 drives the inner cylinder 22 to rotate at a high speed. During the high-speed rotation of the inner cylinder 22, in conjunction with the use of the filter bag 23, the triallyl isocyanurate can be centrifugally crystallized. During this process, the treated liquid will continue to enter the outer cylinder 10. When the liquid level meter 40 detects that there is too much treated liquid in the outer cylinder 10, the treated liquid in the outer cylinder 10 can be discharged through the connecting port 50, thereby cyclically treating the triallyl isocyanurate by centrifugal crystallization.
