[0019] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be construed as a limitation on the protection scope of the present invention.

[0020] Referring to Figures 1-4 , an apparatus for refining dimethyl sulfoxide according to an embodiment of the present invention includes: a bottom plate 1, on the upper surface of which a mounting frame 4, a distillation chamber 10, and a reaction chamber 2 are fixedly connected. The mounting frame 4, the distillation chamber 10, and the reaction chamber 2 are distributed relatively left and right. The distillation chamber 10 and the reaction chamber 2 together form all the components required for the preparation and purification of dimethyl sulfoxide, for purifying dimethyl sulfoxide. Among them, both the distillation chamber 10 and the reaction chamber 2 are commonly used dimethyl sulfoxide preparation devices in life. On the upper surface of the distillation chamber 10, a conduit 5 is fixedly connected. At the upper end of the conduit 5, a feeding pipe 6 is fixedly connected. At the upper end and inside of the feeding pipe 6, a feeding tube 9 and a screw rod 13 are respectively arranged. The feeding tube 9 is fixedly connected to the feeding pipe 6. The conduit 5, the feeding pipe 6, and the feeding tube 9 form a material feeding mechanism, facilitating the addition of dimethyl sulfoxide materials. On the upper surface of the bottom plate 1, a support frame 3 is fixedly connected. The upper end of the support frame 3 is clamped with the feeding pipe 6. The presence of the support frame 3 reduces the load-bearing burden of the feeding pipe 6 and is used to increase the stability of the support frame 3 during use.

[0021] On the side surface of the left end of the screw rod 13, a connection shell 7 is fixedly connected. The connection shell 7 is threadedly connected to the feeding pipe 6, and the left end of the screw rod 13 penetrates through the connection shell 7. The presence of the connection shell 7 improves the convenience of installing the screw rod 13. The connection shell 7 is fixedly connected to the screw rod 13 through a ball bearing. The connection shell 7 is fixedly connected to the outer shaft of the ball bearing, and the screw rod 13 is fixedly connected to the inner shaft of the ball bearing. The connection method between the connection shell 7 and the screw rod 13 improves the stability of the connection shell 7 relative to the screw rod 13 and reduces the influence of the connection shell 7 on the rotational smoothness of the screw rod 13. Inside the feeding pipe 6, a reinforcement base 15 is fixedly connected. The reinforcement base 15 is clamped with the right end of the screw rod 13. The presence of the reinforcement base 15 improves the stability of the screw rod 13 by means of clamping. After the screw rod 13 is clamped with the reinforcement base 15, the screw rod 13 is in a rotatable state relative to the reinforcement base 15, thereby reducing the influence of the reinforcement base 15 on the rotational smoothness of the screw rod 13.

[0022] A servo motor 8 is fixedly connected to the upper surface of the mounting frame 4. A gear set 11 is arranged between the rotating end of the servo motor 8 and the left end of the screw rod 13. The servo motor 8 and the gear set 11 cooperate with each other to form a transmission mechanism, which provides sufficient rotational power for the screw rod 13. The transmission mechanism cooperates with the screw rod 13 to form a screw feeding mechanism. A cavity 14 is arranged inside the screw rod 13, and the cavity 14 provides basic conditions for adding auxiliary components. A heating rod 12 is arranged inside the cavity 14. The right end of the heating rod 12 is in close contact with the upper surface of the mounting frame 4. The heating rod 12 is used to increase the temperature of the screw rod 13, so as to preheat the material during the process of feeding the material for preparing dimethyl sulfoxide. Among them, the heating rod 12 is stationary relative to the screw rod 13, that is, the screw rod 13 cannot drive the heating rod 12 to rotate. The left end of the screw rod 13 is threadedly connected with a cover 16, and the heating rod 12 passes through the cover 16. The cover 16 improves the stability when the heating rod 12 works. The cover 16 and the screw rod 13 are of an integrated structure, and the heating rod 12 is in a rotating state relative to the cover 16 when using the precise device. A limit frame 17 is arranged on the upper surface of the mounting frame 4. The limit frame 17 is clamped with the mounting frame 4, and the left end of the heating rod 12 is located inside the limit frame 17. The limit frame 17 improves the stability of the right end of the heating rod 12.

[0023] Working principle: The operation modes of the distillation chamber 10 and the reaction chamber 2 are the same as those of the common dimethyl sulfoxide preparation equipment. When adding the dimethyl sulfoxide material, the material is added into the guide pipe 6 through the feeding pipe 9, and then the screw feeding mechanism is used to send the material into the distillation chamber 10. When feeding the material, the heating rod 12 can be turned on to increase the stability of the screw rod 13, so as to preheat the material. When maintaining the screw feeding mechanism, since the screw rod 13 is connected to the guide pipe 6 through the connecting shell 7 and the reinforcement base 15, and the connection mode between the two facilitates the disassembly and assembly of the screw rod 13. The heating rod 12 is connected to the screw rod 13 in a socket connection mode, which also improves the convenience of disassembly and assembly of the heating rod 12.
