Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a cylinder body of a high-temperature rotary kiln dryer. Background Art

[0002] Rotary kilns are widely used in various industries. For example, in many production industries such as building materials, metallurgy, chemical engineering, and environmental protection, rotary kilns are used to mechanically, physically, or chemically process solid materials. A rotary kiln dryer is generally used for drying solid materials. After the materials enter the interior of the cylinder body, a heat source is introduced into the jacket inside the cylinder body to dry the materials inside. A driving mechanism for driving the rotation of the cylinder body is also provided on the rotary kiln dryer, so that the materials are fully in contact with the inner wall of the cylinder body for drying.

[0003] The existing rotary kiln dryers generally only introduce a heat exchange medium into the jacket, and the items to be dried are in contact with the cylinder wall to achieve heat exchange drying. However, the contact area between the items and the cylinder wall is small, and the working efficiency is low. Summary of the Invention

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A cylinder body of a high-temperature rotary kiln dryer, including a cylinder body and a jacket fixed on the outer side wall of the cylinder body. A sealed annular cavity is formed between the jacket and the cylinder body. Feeding bins and storage bins are respectively arranged at both ends of the cylinder body. The feeding bins and storage bins are rotationally connected to the cylinder body, and both the feeding bins and storage bins are communicated with the interior of the cylinder body. Medium inlet pipes and medium outlet pipes communicated with the interior of the annular cavity are respectively arranged at the end parts of the cylinder body. A plurality of lifters are arranged on the inner side wall of the cylinder body, and the lifters are of a hollow structure and are communicated with the interior of the annular cavity.

[0006] Furthermore, first flanges and second flanges are respectively vertically bent and arranged at both ends of the cylinder body. The first flange is rotationally connected to the feeding bin, and the second flange is rotationally connected to the storage bin.

[0007] Furthermore, a plurality of first baffle plates and second baffle plates are arranged in a circumferential array inside the annular cavity between the cylinder body and the jacket. The first baffle plates and the second baffle plates are arranged at intervals and are both arranged along the axial direction parallel to the cylinder body. One end of the first baffle plate abuts against the second flange, and a gap is reserved between the other end of the first baffle plate and the first flange. One end of the second baffle plate abuts against the first flange, and a gap is reserved between the other end of the first baffle plate and the second flange.

[0010] Further, the baffle plate is a plate-like structure arranged along the radial direction of the cylinder body.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By arranging a plurality of baffle plates on the inner side wall of the cylinder body of the high-temperature rotary kiln dryer, the materials inside can be scooped up when the cylinder body rotates, avoiding the accumulation of materials at the bottom, making the drying more uniform.

[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a cylinder of a high-temperature rotary kiln dryer, including a cylinder 1 and a jacket 2 fixed on the outer side wall of the cylinder 1. First flanges 101 and second flanges 102 are respectively vertically bent at both ends of the cylinder 1. A sealed annular cavity is formed between the jacket 2 and the cylinder 1. Specifically, the jacket 2 is a cylindrical structure with both ends penetrating, and its two ends are abutted against the first flanges 101 and the second flanges 102, so as to form a sealed cavity for heat exchange inside. Refer to the attached Figure 4, a number of first baffle plates 9 and second baffle plates 10 are arranged in a circumferential array inside the annular cavity between the cylinder body 1 and the jacket 2, and the first baffle plates 9 and the second baffle plates 10 are arranged at intervals and are both arranged along the axial direction parallel to the cylinder body 1. One end of the first baffle plate 9 abuts against the second flanging 102, and there is a gap reserved between the other end of the first baffle plate 9 and the first flanging 101. One end of the second baffle plate 10 abuts against the first flanging 101, and there is a gap reserved between the other end of the first baffle plate 9 and the second flanging 102. The first baffle plates 9 and the second baffle plates 10 divide the inner part of the annular cavity into a number of cavities arranged in a circumferential array centered on the cylinder body 1. The heat exchange medium flows in an S shape inside each cavity through the gap, which can extend the path that the heat exchange medium flows through, improve the heat exchange efficiency. At the same time, the cavities are arranged along the axial direction of the cylinder body 1, making the temperatures at both axial ends of the cylinder body 1 close, and then making the drying of the materials at both ends inside the cylinder body 1 more uniform.

[0022] Feeding bins 6 and storage bins 7 are respectively arranged at both ends of the cylinder body 1. An inlet 601 is arranged at the top of the feeding bin 6, and an outlet 701 is arranged at the bottom of the storage bin 7 for feeding and discharging. Sealing covers that can be opened and closed are installed at the inlet 601 and the outlet 701. The feeding bin 6 and the storage bin 7 are rotationally connected to the cylinder body 1, and both the feeding bin 6 and the storage bin 7 are communicated with the inside of the cylinder body 1. The first flanging 101 is rotationally connected to the feeding bin 6, and the second flanging 102 is rotationally connected to the storage bin 7. During operation, a driving mechanism (not shown in the figure) for driving its rotation is arranged outside the cylinder body 1, and the feeding bin 6 and the storage bin 7 remain stationary, which is convenient for feeding and discharging.

[0023] Medium inlet pipes 3 and medium outlet pipes 4 communicating with the inside of the annular cavity are respectively arranged at both ends of the cylinder body 1. The heat exchange medium enters the inside of the annular cavity through the medium inlet pipes 3, exchanges heat with the materials, and then is discharged to the outside through the medium outlet pipes 4 to dry the materials inside the cylinder body 1. In this embodiment, rotary joints 8 are arranged at the centers of both the feeding bin 6 and the storage bin 7. The specific structure of the rotary joint 8 is prior art and will not be elaborated here. The medium inlet pipes 3 and the medium outlet pipes 4 are respectively connected to the two rotary joints 8, which is convenient for the entry and exit of the medium. Further, the number of rotary joints 8 can also be set to one according to needs, and the medium inlet pipes 3 and the medium outlet pipes 4 are arranged on the same side and connected to the same rotary joint 8 to realize the entry and exit of the medium.

[0024] A number of lifters 5 are arranged on the inner side wall of the cylinder body 1. In this embodiment, the lifters 5 are plate-like structures arranged along the radial direction of the cylinder body 1, which can lift the internal materials when the cylinder body 1 rotates, avoiding the accumulation of materials at the bottom and making the drying more uniform. Further, the lifters 5 are hollow structures, and the lifters 5 are communicated with the inside of the annular cavity. The heat exchange medium enters the inside of the lifters 5, which can increase the heat exchange area with the materials and improve the drying rate.
