[0020] In order to clearly illustrate the design concept of the present invention, the present invention is described below with reference to examples.

[0021] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution of the utility model is clearly and completely described below in conjunction with the drawings in the examples of the utility model. Obviously, the described examples are only part of the examples of the utility model, not all of them. Based on the examples of the utility model, all other implementation methods obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the utility model.

[0022] In the description of this embodiment, the orientations or positional relationships indicated by terms are based on the orientations or positional relationships shown in the accompanying drawings and are merely for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as a limitation on the present invention.

[0023] like Figure 1-2 As shown, the drying equipment for sodium carboxymethyl cellulose production includes the following features: including a feed port 13, a discharge port 14, a conveying component 10, an air suction component and a heating box 1, wherein a support rod 11 is arranged inside the heating box, a heating wire 2 is wound around the support rod 11, and both ends of the heating wire 2 are connected to an external power supply through lead wires, a connecting rod 16 is arranged on the top of the heating box 1, and the heating wire 2 is arranged inside the heating box 1 to prevent dust in the external environment from falling on the heating wire 2, which is difficult to clean, and the heating wire 2 is a plurality of heating wires 2, which are connected end to end and wound on the support rod 11. A connecting piece is provided at the connection of the plurality of heating wires 2. The connecting piece is an annular clamp, and a groove for the heating wire 2 to pass through is provided on the inner side of the annular clamp. In order to prevent the heating wires 2 from contacting each other during winding and affecting the heating uniformity, a spacer for spacing the heating wires is provided on the support rod 11. The spacer can be a bolt, which is connected to the support rod 11 through a threaded hole 9. A countersunk hole 8 is also provided on the threaded hole 9 to facilitate the installation of the spacer. The connecting rod 16 is connected to the frame 7. The bottom of the heating box 1 is provided with a plurality of through holes 15. A fan 3 is provided below the heating box 1. The fan 3 is connected to an external power supply. The conveying assembly 10 is provided in the middle of the drying equipment. The conveying assembly 10 is connected to the frame 7. Specifically, it can be a belt conveying assembly.
