[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] like Figure 1 , Figure 2 The refined cotton drying device shown in the figure comprises an outer cylinder 1, an inner cylinder 2 and a rotating driving member 3. The outer cylinder 1 is a cylindrical shell, and the outer cylinder 1 is placed horizontally through two bases 11. The left end of the outer cylinder 1 is sealed, and the right end of the outer cylinder 1 is open. The opening is hinged with an end cover 12 through a hinge, and the end cover 12 can achieve the sealing of the outer cylinder 1.

[0027] like Figure 1-3 As shown, an air inlet chamber 13 communicating with the interior of the outer tube 1 is fixed on the lower side of the outer tube 1, and the air inlet chamber 13 is connected to a hot air mechanism (not shown) through a pipeline, and is used to send high-temperature hot air into the outer tube 1. An exhaust chamber 14 communicating with the interior of the outer tube 1 is fixed on the upper side of the outer tube 1, and the exhaust chamber 14 is connected to an exhaust fan (not shown) through a pipeline, and is used to discharge the humid air in the outer tube 1.

[0028] The outer tube 1 is coated with a heat-insulating layer to reduce heat loss. The connection between the air inlet chamber 13 and the outer tube 1 and the connection between the air outlet chamber 14 and the outer tube 1 are fixedly installed with mesh plates 15. The mesh plates 15 at the air inlet chamber 13 are used to improve the uniformity of hot air entering the inner part of the outer tube 1. The baffle plates 15 at the air outlet chamber 14 can prevent refined cotton wool from clogging the exhaust fan, thereby ensuring the safe and stable operation of the equipment.

[0029] like Figure 1 , Figure 4-6 As shown, the inner cylinder 2 is a cylindrical shell with one end open, and the inner cylinder 2 is coaxially installed in the outer cylinder 1, so that the opening of the inner cylinder 2 faces the opening of the outer cylinder 1. A plurality of ventilation holes 21 are arranged in an array on the cylinder wall of the inner cylinder 2, so that hot air can enter the inner cylinder 2 and moisture can be discharged from the inner cylinder 2.

[0030] like Figure 4 , Figure 5 As shown, two fixing rings 22 are fixed on the outer wall of the inner cylinder 2, and the two fixing rings 22 are respectively located at the two ends of the inner cylinder 2. A plurality of guide wheels 23 are installed on the side of each fixing ring 22, and the plurality of guide wheels 23 are evenly distributed on the circumference of the fixing ring 22. The outer edge of the guide wheel 23 extends out of the outer surface of the fixing ring 22 and abuts against the inner wall of the outer cylinder 1, so that the inner cylinder 2 can rotate in the outer cylinder 1.

[0031] like Figure 2 , Figure 6 As shown, a connecting flange is welded and fixed at the center of the bottom of the inner cylinder 2, and a rotating shaft 24 is fixed on the connecting flange. The rotating drive member 3 is fixed at the left end of the outer cylinder 1, and the rotating shaft 24 passes through the outer cylinder 1 and is connected to the output shaft of the rotating drive member 3. The rotating drive member 3 rotates, and the inner cylinder 2 is driven to rotate through the rotating shaft 24. Among them, the rotating drive member 3 is a worm gear reduction motor. By installing a rotatable inner cylinder 2 in the outer cylinder 1, the refined cotton is constantly turned over during drying, which improves the uniformity of the refined cotton being heated, ensures the quality of the refined cotton, and improves the drying efficiency. At the same time, hot air enters from the lower side of the outer cylinder 1, and humid air is discharged from the upper side of the outer cylinder 1, which further improves the drying efficiency.

[0032] As a preferred embodiment of the present application, four spiral blades 4 are fixed to the inner wall of the inner barrel 2, and the spiral blades 4 run through the axial length of the inner barrel 2. By installing the spiral blades 4 in the inner barrel 2, on the one hand, the turning effect of the refined cotton can be increased, the uniformity of drying can be ensured, and the drying efficiency can be improved. On the other hand, by adjusting the forward and reverse rotation of the inner barrel 2, the spiral blades 4 can be used to realize automatic feeding and unloading of the refined cotton. Preferably, the spiral blades 4 and the barrel wall of the inner barrel 2 are smoothly transitioned through an arc surface to prevent the refined cotton from being entangled on the spiral blades 4.

[0033] As a preferred embodiment of the present application, a temperature sensor (not shown) is installed on the inner side of the cover plate 12, and the temperature sensor is fixed on an extension rod (not shown), so that the temperature sensor can extend into the inner drum 2 to achieve accurate monitoring of the drying temperature.

[0034] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings.
