One end of 54) is connected to an annular groove (56), and multiple ash inlet holes (561) are provided in the annular groove (56); a third through hole (541) is provided on the top of the ash collection box (54), and a movable plate (57) is bolted to the third through hole (541). A sealing plate (571) is embedded on the side of the movable plate (57) near the ash collection box (54), and a filter plate (58) is fixed to the inner side of the movable plate (57). An ash collection trough (59) is installed on the side of the filter plate (58) near the ash inlet pipe.

8. The synthetic resin preparation apparatus according to claim 3, characterized in that: Two sets of vibration mechanisms (6) are installed on both sides of the mixing cylinder (1).

9. The synthetic resin preparation apparatus according to claim 8, characterized in that: Each vibration mechanism (6) includes a second fixed plate (61) mounted on the outer wall of the mixing cylinder (1), a second guide rod (62) fixed to the side of the second fixed plate (61) away from the mixing cylinder (1), a second sliding sleeve (63) slidably connected to the second guide rod (62), a reciprocating vibration rod (64) fixed to the bottom of the second sliding sleeve (63), and a cam (65) eccentrically connected to the output shaft of the drive motor (31); one end of the reciprocating vibration rod (64) away from the mixing cylinder (1) abuts against the outer peripheral surface of the cam (65), and the other end can abut against the outer wall of the mixing cylinder (1); a plurality of horizontal springs (66) are fixed between the second sliding sleeve (63) and the second fixed plate (61).

10. A method for preparing a synthetic resin, based on the synthetic resin preparation apparatus according to any one of claims 1-9, characterized in that: Includes the following steps: When it is necessary to stir the raw materials, the raw materials are first fed into the mixing drum (1) through the feed pipe (12), and then the stirring motor (13) is started. At this time, the output shaft of the stirring motor (13) drives the rotating shaft (14) to rotate. The rotating shaft (14) rotates and drives the stirring plate (15) to rotate, so that the raw materials can be stirred. After the raw materials are mixed, the discharge pipe (16) is opened through the valve, and then the material is discharged through the discharge pipe (16). When the raw materials need to be stirred again and the inside of the transparent plate (18) needs to be cleaned in advance, the drive motor (31) is started first. At this time, the output shaft of the drive motor (31) drives the first bevel gear (32) to rotate. The rotation of the first bevel gear (32) drives the second bevel gear (34) to rotate. The rotation of the second bevel gear (34) drives the horizontal shaft (33) to rotate. The rotation of the horizontal shaft (33) drives the reciprocating screw (26) to rotate. The rotation of the reciprocating screw (26) drives the first sliding sleeve (27) to move back and forth. The reciprocating movement of the first sliding sleeve (27) drives the cleaning plate (21) to move back and forth. The reciprocating movement of the cleaning plate (21) drives the brush (22) to move back and forth. The reciprocating movement of the brush (22) can clean the inside of the transparent plate (18). In addition, when the cleaning plate (21) moves towards the observation port (17), the cleaning plate (21) can clean the inside of the transparent plate (18). Under the action of the inclined plane (421), the blocking plate (42) is driven to move upward. The upward movement of the blocking plate (42) drives the reset block (43) to move upward. The upward movement of the reset block (43) presses against the reset spring (45). When the blocking plate (42) retracts to the first through hole (171), the reset block (43) drives the blocking plate (42) to reset under the action of the reset spring (45), thus facilitating the blocking of the end of the first through hole (171) near the observation port (17). Furthermore, when the output shaft of the drive motor (31) drives the first bevel gear (32) to rotate, the cam (65) rotates, and then the reciprocating vibration rod (64) moves back and forth under the action of the cam (65) and the horizontal spring (66), thus facilitating the vibration of the side wall of the mixing drum (1), thereby reducing the dust adhering to the inner wall of the mixing drum (1).
