[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4A rotary kiln dryer with good heat preservation comprises a cylinder 1 and two protective plates 2, a controller 7 is fixedly arranged on the outer wall of the protective plate 2, a docking plate 3 is arranged at both ends of the protective plate 2, and the two docking plates 3 are fixed by screws, a plurality of heating tubes 9 electrically connected to the controller 7 are arranged on the inner wall of the protective plate 2, a heat preservation plate 8 is arranged on the inner side of the protective plate 2, a plurality of placement grooves 10 are arranged on the outer wall of the heat preservation plate 8, the heating tubes 9 cooperate with the placement grooves 10, the heat preservation plate 8 contacts the outer wall of the cylinder 1, and when the protective plate 2 and the heat preservation plate 8 are installed, the heating tubes 9 are located inside the placement grooves 10, so that the heat preservation The plate 8 contacts the protective plate 2 and the cylinder 1. The protective plate 2 can provide a protective effect for the cylinder 1, so that the cylinder 1 is not easily damaged after being subjected to external force. The heat preservation plate 8 can provide a good heat preservation effect for the cylinder 1. When the outside temperature is low, the controller 7 is started to energize the heating tube 9 and generate heat energy (the heating tube 9 can be an electric heating tube, and an independent power supply can be set inside the controller 7 to provide electric energy to the heating tube 9. Since electric heating tubes are very common in life, there is no need to make too much description about them here). When the temperature is low, the drying efficiency of the rotary kiln dryer can be further improved.

[0022] When the insulation board 8 is damaged, the protective plate 2 is removed from the outer wall of the cylinder 1, and then the insulation board 8 is removed from the inner wall of the protective plate 2. The insulation board 8 is bonded to the inner wall of the protective plate 2, and the bonding method allows the insulation board 8 to be easily replaced.

[0023] The docking plate 3 lacks a positioning structure on the outer wall of the cylinder 1, which makes it inconvenient to install the protective plate 2 on the outer wall of the cylinder 1. A positioning groove 5 is provided inside the docking plate 3, and a clamping groove 6 is provided on the top of the positioning groove 5. Two positioning seats 11 are symmetrically arranged on the outer wall of the cylinder 1, and a cavity 12 is provided inside the positioning seat 11. A spring is provided inside the cavity 12, and a clamping block 13 cooperating with the clamping groove 6 is provided on the top of the spring. The spring can provide an elastic force to the clamping block 13. Through the cooperation between the clamping block 13 and the clamping groove 6, a positioning structure can be provided for the docking plate 3 on the outer wall of the cylinder 1, so that the protective plate 2 can be conveniently installed on the outer wall of the cylinder 1.

[0024] Furthermore, the block 13 and the slot 6 are both arc-shaped structures. When the pulling force provided to the docking plate 3 is greater than the elastic force of the spring, the block 13 can compress the spring, so that the protective plate 2 can be disassembled. The structure is simple and the operation is convenient.

[0025] In this structure, the positioning seat 11 is fixed to the outer wall of the cylinder 1 by bolts 4 . The positioning seat 11 is provided with a plurality of grooves. The bolts 4 are located inside the grooves, so that the positioning seat 11 can be easily assembled on the outer wall of the cylinder 1 .
