The height of the socket 19 is equal to the height of the ring body 6. A first fixing column 3 and a second fixing column 22 are respectively provided on the base 16 and located at the outer sides of the two ends of the shell 13. A pair of ring bodies 6 are rotatably connected to the first fixing column 3 through a rotating connector 4, and a pair of ring bodies 6 can be rotated to be inserted into the socket 19 and coaxial with the shell 13. The ring body 6 and the second fixing column 22 are connected by a locking assembly; the ring body 6 The inner wall is detachably provided with a screen 8, a feed port 1 is provided at the center of the cover plate 2, and the side surfaces of the ring body 6 and the bottom groove 18 are respectively provided with a graded discharge port 7; a support ring 11 is provided at the bottom of the inner wall of the ring body 6, the screen 8 is seated on the support ring 11, and is detachably connected to the support ring 11 by a screw 9; the locking assembly includes a first clamp 10, a second clamp 21 and a bolt 24, the side surface of the ring body 6 and the side corresponding to the side away from the rotating connection 4 is provided with a first clamp 10, and the second fixing column 22 is provided with a second clamp at a height position corresponding to the ring body 6 21, the ring body 6 is rotated to be inserted into the socket 19, and the first clamp 10 and the second clamp 21 are connected by a bolt 24 after abutting; a semi-cylindrical protective ring 5 is provided on the side surface of the ring body 6, and the height of the protective ring 5 is greater than the height of the ring body 6. After the ring body 6 is inserted into the socket 19, the protective ring 5 is buckled at the abutment between the ring body 6 and the cover plate 2, the limit ring 20, and the base 16; the upper ends of the first fixing column 3 and the second fixing column 22 are fixedly connected to the cover plate 2 by a fixing ring 23, and the shell 13 and the first fixing column 3 and the second fixing column 22 are fixedly connected by a fixing connector 12.

[0020] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0021] According to the instruction manual Figure 1-4It can be seen that in the present invention, the inner wall of the semi-cylindrical shell 13 on the base 16 is sequentially provided with a cover plate 2, a limit ring 20 and a bottom groove 18 from top to bottom, and a pair of ring bodies 6 are rotatably connected to the first fixed column 3 on the base 16 through a rotating connector 4, and can be inserted into the socket 19 formed between the cover plate 2 and the limit ring 20 and between the limit ring 20 and the bottom groove 18 by rotation, and connected to the second fixed column 22 through a locking assembly. Since the outer diameters of the cover plate 2, the limit ring 20, the bottom groove 18 and the ring body 6 are equal to the inner diameter of the shell 13, and the height of the socket 19 is equal to the height of the ring body 6, when the ring body 6 is rotated and is coaxial with the shell 13, the cover plate 2, the ring body 6, the limit ring 20 and the base 16 form a complete and enclosed working space, as shown in FIG. Figure 3 As shown, at this point, screening work can begin.

[0022] During operation, the feed port 1 on the cover plate 2 is fed with talc masterbatch to be screened. Due to the operation of the vibration spring 14 between the bottom plate 15 and the base 16 and the vibration motor 17 at the bottom of the base 16, the base 16 and the components on the base 16 can be driven to vibrate. The talc masterbatch entering from the feed port 11 falls on the detachable screen 8 installed on the inner wall of the ring body 6 and is vibrated and screened. The structure of the pair of ring bodies 6 is the same, and the only difference is the mesh size of the screen 8. The purpose is to achieve graded screening, which is well understood by those skilled in the art. The material filtered and screened by the screen 8 is discharged from the graded discharge port 7 on the side wall of the ring body 6 and the bottom trough 18 for collection.

[0023] When it is necessary to replace the screen 8, clean the screen 8 or perform internal maintenance, the staff opens the locking assembly and rotates the ring body 6 out of the socket 19, or out of the shell 13, as shown in FIG. Figure 1 and Figure 2 As shown, due to the increase in operating space, it is convenient for personnel to replace, clean and repair the screen 8 and the equipment. The method of rotating the ring body 6 to separate the screen 8 from the shell 13 can facilitate personnel operations, and quickly removing the screen 8 improves the efficiency of replacement or cleaning. The operation is simple and convenient, which improves work efficiency.

[0024] Among them, a support ring 11 is provided at the bottom of the inner side wall of the ring body 6, and the screen 8 is seated on the support ring 11 and is detachably connected to the support ring 11 by screws 9. The screws 9 fix the screen 8, and the installation is simple and convenient. Of course, the screen 8 here can also be detachably connected to the support ring 11 by a snap buckle, as long as the detachable connection of the screen 8 can be achieved.

[0025] The locking assembly includes a first clamp 10, a second clamp 21, and a bolt 24. The first clamp 10 is provided on the side surface of the ring body 6, away from the rotating connector 4. The second clamp 21 is provided on the second fixing post 22 at a height corresponding to the ring body 6. During operation, after the ring body 6 is rotated and inserted into the socket 19, the first clamp 10 and the second clamp 21 abut against each other, and then a detachable connection is established by the bolt 24. The structure is simple and can be operated by ordinary personnel.

[0026] Among them, a semi-cylindrical protective ring 5 is provided on the side surface of the ring body 6. The height of the protective ring 5 is greater than the height of the ring body 6, that is, it protrudes from the upper and lower edges of the ring body 6. When the ring body 6 is inserted into the socket 19, the protective ring 5 can be buckled at the junction of the ring body 6 and the cover plate 2, the limiting ring 20, and the base 16. The protective ring 5 can be connected to the end face of the shell 13 to form a sealed ring, thereby increasing the sealing and stability of the ring body 6 during operation.

[0027] Among them, the upper ends of the first fixing column 3 and the second fixing column 22 are fixedly connected to the cover plate 2 through a fixing ring 23, and the shell 13 and the first fixing column 3 and the second fixing column 22 are fixedly connected through a fixing connector 12, which increases the overall stability of the device and improves its service life.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
