Description

Technical Field

[0001] This utility model relates to the field of chemical raw material drying technology, specifically to a chemical raw material drying device. Background Technology

[0002] Chemical raw materials are raw materials produced using chemical methods. They include inorganic chemical products other than fertilizers, inorganic pesticides, and inorganic pigments, as well as various products mainly made from polymer materials in the organic synthesis industry. They are important raw materials for various industrial sectors. In addition to being widely used in the chemical industry, they are also needed in mining, metallurgy, machinery, light industry and other industries. In the actual production and manufacturing of chemical raw materials, chemical raw material drying equipment is required to complete the drying process.

[0003] Currently, in actual use, most chemical raw material drying equipment dries from the outside in gradually. During the drying process, most of the water vapor emitted from the raw material rises from the bottom to the top with the air and is then discharged from the exhaust pipe at the top. This drying method is inefficient and the drying effect is not good enough. Utility Model Content

[0027] This utility model provides, for example Figures 1 to 6 The chemical raw material drying equipment shown includes:

[0028] Drying oven 1, with a support frame 22 fixedly installed on the outside of the bottom end of the drying oven 1, and a heating plate 2 inside the drying oven 1, with multiple heating rods 3 integrally connected to the inner end of the heating plate 2;

[0029] Rotating tube 4 is located in the middle of the heating plate 2 and the drying chamber 1. The top end of rotating tube 4 passes through the top end of drying chamber 1 and is rotatably connected to the top end of drying chamber 1 through a bearing. A power component is connected to the top end of rotating tube 4. Multiple stirring tubes 5 are fixedly provided at the outer end of rotating tube 4 and are connected to its interior. Multiple stirring rods 6 are fixedly provided at the top and bottom ends of stirring tubes 5. Multiple stirring tubes 5 and stirring rods 6 connected to them are distributed at intervals with multiple heating rods 3. Multiple air inlets 7 are opened on the side of stirring tube 5 opposite to its rotation direction. A filter screen plate 8 is fixedly provided on the inner wall of air inlet 7.

[0030] The power assembly includes a motor 10 fixedly mounted on the top of the drying chamber 1. The output shaft of the motor 10 is fixedly connected to a rotating shaft 11. The bottom end of the rotating shaft 11 is rotatably connected to the top of the drying chamber 1. A first gear 12 is fixedly mounted on the outer end of the rotating shaft 11. A second gear 13 is fixedly mounted on the top of the rotating tube 4. The first gear 12 and the second gear 13 mesh with each other.

[0031] A filter box 14 is fixedly installed at the rear top of the drying box 1. An air outlet pipe 9 is fixedly installed at the front end of the filter box 14 and communicates with its interior. One end of the air outlet pipe 9 passes through the top of the rotating tube 4 and communicates with the interior of the rotating tube 4. One end of the air outlet pipe 9 is rotatably connected to the top of the rotating tube 4 through a sealed bearing. A fan 15 is fixedly installed at the rear end of the filter box 14. The air inlet of the fan 15 is located inside the filter box 14. Two insertion slots 16 are opened on the inner wall of the filter box 14. A dehumidifying cotton plate 17 and an activated carbon filter plate 18 are respectively inserted into the two insertion slots 16. A door 19 is hinged to one side of the filter box 14.

[0032] A feeding pipe 20 connected to the interior of the drying chamber 1 is fixedly installed at the top of the drying chamber 1. A first valve is fixedly installed on the feeding pipe 20. A discharge pipe 21 connected to the interior of the drying chamber 1 is fixedly installed at the bottom of the drying chamber 1. A second valve is fixedly installed on the discharge pipe 21.

[0033] The chemical raw material to be dried is added into the drying chamber 1 and heating plate 2 through the feeding pipe 20. The heating plate 2 and multiple heating rods 3 heat and dry the chemical raw material. The motor 10 is started, and its output shaft drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the first gear 12 to rotate, which in turn drives the second gear 13. The second gear 13 drives the rotating tube 4 to rotate, which in turn drives multiple stirring tubes 5 to rotate. The stirring tubes 5 and stirring rods 6 rotate, thus stirring the raw material. This ensures uniform drying of the raw material and improves its quality. To improve drying efficiency, during the heating and drying process, the fan 15 is started, and the hot air inside the drying chamber 1 enters the interior of multiple stirring tubes 5 through multiple air inlets 7, and then enters the interior of the filter chamber 14 through the rotating tube 4 and the air outlet 9. The water vapor generated during drying is absorbed by the dehumidifying cotton plate 17, while the toxic substances in the raw materials are filtered and absorbed by the activated carbon filter plate 18. The hot air is discharged quickly, and the gases generated during the drying process are filtered by the dehumidifying cotton plate 17 and the activated carbon filter plate 18, which can filter out the moisture and toxic substances, effectively protecting the environment.

[0034] This invention uses a heating plate 2 and multiple heating rods 3 to heat and dry the raw materials, and then uses multiple stirring tubes 5 and stirring rods 6 to stir the raw materials. This can quickly dry the moisture in the raw materials. Then, the hot air mixed with moisture is discharged from the drying chamber 1 from multiple directions through multiple air inlets 7, which effectively improves the drying efficiency of chemical raw materials and achieves a good drying effect. This embodiment specifically solves the problem that in the actual use of existing chemical raw material drying equipment, most of them dry from the outside to the inside, and most of the moisture emitted from the raw materials during the drying process rises from the bottom to the top with the air and is then discharged from the exhaust pipe at the top. This drying method is inefficient and the drying effect is not good enough.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
