[0025] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments. The present utility model provides the following embodiments.

[0027] Such as Figures 1 to 6 , a reaction kettle for preparing cross-linked polystyrene includes: a reaction kettle main body 1, a bracket 2, a cleaning mechanism 3 and a stirring mechanism 4. Four brackets 2 are symmetrically and fixedly connected to the surface of the reaction kettle main body 1. A cleaning mechanism 3 and a stirring mechanism 4 are installed inside the reaction kettle main body 1. The cleaning mechanism 3 includes a toothed ring 31, a first gear 32 and a cleaning plate 33. The toothed ring 31 is arranged at the upper end inside the reaction kettle main body 1. The surface of the toothed ring 31 is equidistantly and fixedly connected with teeth. The teeth surface of the toothed ring 31 is meshed with a first gear 32. The bottom of the toothed ring 31 is fixedly connected with a cleaning plate 33, and the surface of the cleaning plate 33 is attached to the inner side wall of the reaction kettle main body 1. The stirring mechanism 4 includes a stirring installation shell 41, a second gear 42, a third gear 43 and an auger rod 44. The stirring installation shell 41 is fixedly installed on the upper inner wall of the reaction kettle main body 1. Cylindrical grooves are symmetrically opened inside the stirring installation shell 41. A second gear 42 and a third gear 43 are symmetrically rotatably connected inside the stirring installation shell 41, and the second gear 42 and the third gear 43 are meshed with each other. The bottom of the second gear 42 and the third gear 43 is fixedly connected with an auger rod 44, and the auger rod 44 rotates inside the cylindrical groove of the stirring installation shell 41.

[0028] In this embodiment, rotate the first gear 32. The teeth of the first gear 32 contact the teeth of the toothed ring 31, driving the toothed ring 31 to rotate. The cleaning plate 33 moves closely along the inner wall of the reactor main body 1. The second gear 42 inside the stirring mounting shell 41 rotates. The teeth of the second gear 42 contact the teeth of the third gear 43, driving the third gear 43 to rotate inside the stirring mounting shell 41. The second gear 42 and the third gear 43 control the relative rotation of the auger rod 44 inside the cylindrical groove of the stirring mounting shell 41, feeding the material for preparing crosslinked polystyrene into the inside of the reactor main body 1. The auger rod 44 sucks the material from the bottom end of the cylindrical groove of the stirring mounting shell 41, conveys it upward along the inside of the cylindrical groove of the stirring mounting shell 41, and discharges it from the top end of the cylindrical groove of the stirring mounting shell 41, stirring the material reciprocally to ensure the uniformity of stirring. During the process of reciprocal stirring, a small amount of material will adhere to the side inner wall of the reactor main body 1. The toothed ring 31 drives the cleaning plate 33 to rotate and move, and the cleaning plate 33 is used to remove the material adhering to the side inner wall of the reactor main body 1, preventing the material from adhering to the side inner wall of the reactor main body 1 and affecting the preparation efficiency of crosslinked polystyrene.

[0029] As shown in the Figure 3 attached figure, the cleaning mechanism 3 further includes an annular groove 34 and an annular block 35. An annular groove 34 is formed on the surface of the toothed ring 31, and an annular block 35 is slidably connected inside the annular groove 34, and the surface of the annular block 35 is fixedly connected to the side inner wall of the reactor main body 1.

[0030] In this embodiment, when the toothed ring 31 rotates, the annular groove 34 slides along the surface of the annular block 35, slidably connecting the toothed ring 31 with the side inner wall of the reactor main body 1 to ensure the stability of the rotation of the toothed ring 31.

[0031] As shown in the Figure 3 attached figure, the cleaning mechanism 3 further includes a first motor 36. The first motor 36 is fixedly installed on the surface of the motor bracket at the top of the reactor main body 1, and the output shaft of the first motor 36 passes through the inside of the reactor main body 1 and is fixedly connected to the first gear 32.

[0032] In this embodiment, start the first motor 36. The output shaft of the first motor 36 drives the first gear 32 to rotate, providing drive for the rotation of the first gear 32.

[0033] As shown in the Figure 4 attached figure, the stirring mechanism 4 further includes a second motor 45. The second motor 45 is fixedly installed on the surface of the motor bracket at the top of the reactor main body 1, and the output shaft of the second motor 45 passes through the inside of the stirring mounting shell 41 and is fixedly connected to the second gear 42.

[0034] In this embodiment, start the second motor 45. The output shaft of the second motor 45 drives the second gear 42 to rotate, providing drive for the rotation of the second gear 42.

[0035] As shown in the appendix Figure 5 As shown, the stirring mechanism 4 further includes a bearing 46. The bottom end of the auger rod 44 is fixedly connected to the bearing 46, and the outer ring of the bearing 46 is fixedly connected to the inner wall of the cylindrical groove of the stirring mounting shell 41.

[0036] In this embodiment, when the auger rod 44 rotates, the inner ring of the bearing 46 rotates and the outer ring of the bearing 46 remains stationary, which increases the rotational stability of the auger rod 44 and prevents the auger rod 44 from shaking when conveying materials, thus affecting the mixing and stirring of the materials.

[0037] As shown in the appendix Figure 6 As shown, the surface of the reactor main body 1 is symmetrically and slidably penetrated with a sealing mechanism 5. The sealing mechanism 5 includes a sealing plate 51 and an electric push rod 52. The sealing plate 51 is slidably mounted on the surface of the reactor main body 1 and passes through the inside of the reactor main body 1. The surface of the sealing plate 51 away from the reactor main body 1 is fixedly connected to the electric push rod 52, and the end of the electric push rod 52 away from the sealing plate 51 is fixedly connected to the surface of the bracket 2.

[0038] In this embodiment, when the electric push rod 52 extends, it drives the sealing plate 51 to approach the reactor main body 1. The sealing plate 51 enters the inside of the reactor main body 1 through the groove on the surface of the reactor main body 1. The two sealing plates 51 approach each other and are tightly attached. When the electric push rod 52 contracts, the two sealing plates 51 move away from each other. When the stirring mechanism 4 reciprocally stirs the materials, the tightly attached sealing plates 51 prevent the stirred materials from entering the bottom of the reactor main body 1, resulting in a phenomenon where stirring cannot be carried out. After stirring is completed, the separated sealing plates 51 facilitate the stirred materials to enter the bottom discharge port of the reactor main body 1.

[0039] The above content further elaborates on the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as falling within the protection scope determined by the claims submitted for the present utility model.
