[0053] Specifically, when the driving shaft 201 rotates, it drives the driving gear 202 to rotate in the mounting frame 3. The driving gear 202 cooperates with the fixed gear ring 301 to drive the movable gear 302 to move in the mounting frame 3, so that the tank body 4 rotates around the central axis of the driving shaft 201. When the movable gear 302 moves, it drives the reciprocating screw rod 503 on the rotating ring 303 to rotate, and the sleeve 501 moves axially along the reciprocating screw rod 503.

An L-shaped plate (8) is movably connected between the end of the stirring rod (7) and the first bevel gear (6), and a second bevel gear (801) meshing with the first bevel gear (6) is provided at the end of the stirring rod (7).

4. A methyl methoxyacetate removal device for preparing methoxyacetic acid according to claim 3, characterized in that: The stirring rod (7) comprises a main rod body (701) connected to the second bevel gear (801) and a sleeve (702) sleeved on the outside of the main rod body (701) and connected to the tank body (4); a guide bar (7011) is fixedly provided on the outside of the main rod body (701); a guide groove (7021) for the guide bar (7011) to slide is provided on the inner wall of the sleeve (702); a connecting shaft (703) connected to the stirring blade (704) is provided on the main rod body (701); a concave hole (705) for the connecting shaft (703) to move is provided on the sleeve (702); a driven gear (7031) is provided on the connecting shaft (703); and a rack plate (7051) meshing with the driven gear (7031) is provided on the inner wall of the concave hole (705).

5. A method for using the device for removing methyl methoxyacetate for preparing methoxyacetic acid according to claim 4, characterized in that: The following steps are involved: S1: firstly, the electric heating element in the heating chamber (401) is operated to heat the material in the tank body (4) through the heating chamber (401), and then the vacuum pump (4051) is controlled to operate, and the vacuum pump (4051) draws the tank body (4) into a vacuum state through the conduit (405); S2: Then, the driving motor (2) is controlled to operate, and the output shaft of the driving motor (2) drives the driving shaft (201) to rotate. When the driving gear (202) rotates, the outer abutting rod (10) presses against the inclined surface of the force bearing block (9) through the ball (1001), so that the mounting frame (3) swings relative to the driving shaft (201), thereby causing each end of the tank body (4) arranged on the upper side of the mounting frame (3) to be intermittently raised and lowered, so that the material in the tank body (4) flows from one end to the other end; S3: When the driving shaft (201) rotates, the driving gear (202) can be driven to rotate in the mounting frame (3) through the third elastic telescopic rod (13); the driving gear (202) cooperates with the fixed gear ring (301) to drive the movable gear (302) to move in the mounting frame (3), so that the tank body (4) rotates around the central axis of the driving shaft (201); when the movable gear (302) moves, the reciprocating screw (503) on the rotating ring (303) is driven to rotate, and the sleeve (501) moves along the axial direction of the reciprocating screw (503); S4: When the sleeve (501) moves upward along the reciprocating screw rod (503), the sleeve (501) drives the tank body (4) to move upward through the connecting piece (502) and the transverse movement assembly. When the sleeve (501) moves downward along the reciprocating screw rod (503), the sleeve (501) drives the tank body (4) to move downward through the connecting piece (502) and the transverse movement assembly, so that the material in the tank body (4) can be subjected to disturbance forces in multiple directions. S5: When the reciprocating screw (503) rotates, the first bevel gear (6) is driven to rotate via the first elastic telescopic rod (504). When the first bevel gear (6) rotates, the tank body (4) is pushed to swing back and forth between the two transverse moving components via the fixed rod (601) and the transverse moving rod (602). When the first bevel gear (6) rotates, it meshes with the second bevel gear (801), so that the stirring rod (7) drives the stirring blade (704) to rotate in the tank body (4). In conjunction with the reciprocating shaking of the tank body (4), the stirring blade (704) can stir and mix materials at different positions in the tank body (4), thereby accelerating the uniform heating of the materials in the tank body (4), thereby allowing the products to be fractionated out quickly.
