Abstract
Description
Technical Field
[0001] This utility model relates to a calcium hydroxide drying device, specifically a calcium hydroxide drying device, belonging to the field of calcium hydroxide drying technology. Background Technology
[0002] Calcium hydroxide, as a basic inorganic compound, is widely used in construction, environmental protection, chemical industry, agriculture and other fields due to its alkalinity, hygroscopicity and chemical reactivity. Drying calcium hydroxide is a key step in its production, storage and application. The main purpose is to remove moisture to prevent deliquescence, maintain chemical stability and improve performance.
[0003] A drying apparatus for processing calcium hydroxide is disclosed in Chinese patent application publication CN218034162U. The apparatus introduces material into the cylinder through a feed pipe. After the hot air blower is powered on and started, it draws in external air, which is then filtered and dehumidified by the air filter before being heated. The hot air moves upward and the evaporated water vapor is discharged through the exhaust pipe. However, some of the calcium hydroxide material that is trapped is difficult to escape due to the obstruction of the dust filter.
[0004] However, during the implementation of the above-mentioned patented technical solution, the damp calcium hydroxide will clump together, making it difficult for hot air to dry the inside of the clump. When the calcium hydroxide is in a damp state, the particles stick together, making it very easy for the calcium hydroxide to clump together or even harden. When drying the clump of calcium hydroxide, it is difficult for hot air to reach the inside of the clump, making the drying time of the clump longer.
[0005] Therefore, a calcium hydroxide drying device is proposed here. Utility Model Content

[0013] Preferably, the drying oven is provided with a drying mechanism on the outside. The drying mechanism includes a hot air blower fixed on the outer surface of the drying oven and two filter screens fixed on the inner wall of the drying oven. Both filter screens are adapted to the hot air blower.

[0014] This utility model provides a calcium hydroxide drying device, which has the following beneficial effects:
[0015] This calcium hydroxide drying device, through the setting of a grinding and dispersing mechanism, can grind and disperse clumps of calcium hydroxide, making it easier for hot air to dry the calcium hydroxide. Compared with directly drying clumps of calcium hydroxide, it can save more time and avoid the difficulty of drying the inside of clumps of calcium hydroxide with hot air, thereby improving drying efficiency.
[0016] This calcium hydroxide drying device, through the setting of a conveying mechanism and a drying mechanism, dries the calcium hydroxide with hot air blown by a hot air blower during the process of the calcium hydroxide falling after grinding.

Dispersing plates 25 are fixed on the outer surfaces of the two rotating rods 24. A connecting frame 26 is fixed to the end of the rotating rod 24 closest to the pinion 22. A cylindrical block 27 is fixed to the outer surface of the pinion 22. The cylindrical block 27 is slidably connected to the inner wall of the connecting frame 26. When the pinion 22 rotates, it pushes the connecting frame 26 to swing back and forth through the cylindrical block 27.
[0029] Please refer to this carefully. Figure 3 One of the two rotating rods 24, the one furthest from the pinion 22, has a connecting rod 28 fixed at the end closest to the pinion 22. A hinge rod 29 is hinged to the outer surface of the connecting rod 28. The end of the hinge rod 29 furthest from the connecting rod 28 is hinged to the outer surface of the connecting frame 26. Under the connecting action of the hinge rod 29, when the connecting frame 26 swings back and forth, it drives the connecting rod 28 to swing back and forth. The connecting frame 26 and the connecting rod 28 drive the two dispersing plates 25 to swing back and forth. The dispersing plates 25 can disperse the ground calcium hydroxide powder.
[0030] Please refer to this carefully. Figure 2 The grinding and dispersing mechanism 2 also includes a first motor 210 fixed on the outer surface of the drying chamber 1. The output shaft end of the first motor 210 is fixed on the outer surface of the large gear 23, and the first motor 210 provides power for the rotation of the large gear 23.
[0031] Please refer to this carefully. Figure 1 and Figure 4 The drying box 1 is provided with a conveying mechanism 3 on the outside. The conveying mechanism 3 includes a conveying box 31. The inner wall of the conveying box 31 is rotatably connected to a rotating shaft 34. The outer surface of the rotating shaft 34 is fixed with a spiral conveying blade 35. Calcium hydroxide in the conveying box 31 can be conveyed upward by the spiral conveying blade 35, or it can be discharged at the bottom of the conveying box 31.
[0032] Please refer to this carefully. Figure 4A second motor 36 is fixed on the upper surface of the conveyor box 31. The output shaft of the second motor 36 is fixed to the top of the rotating shaft 34. The second motor 36 provides power for the rotation of the rotating shaft 34.
[0033] Please refer to this carefully. Figure 4 An inclined connecting bucket 32 is fixed to the outer surface of the conveying box 31. The inclined connecting bucket 32 is fixed to the outer surface of the drying box 1. An inclined connecting pipe 33 is fixed to the outer surface of the conveying box 31. The inclined connecting pipe 33 is fixed to the outer surface of the drying box 1. Calcium hydroxide powder in the drying box 1 can enter the conveying box 31 through the inclined connecting bucket 32. After being conveyed upward by the spiral conveying blades 35, the calcium hydroxide powder in the conveying box 31 can be conveyed back into the drying box 1 through the inclined connecting pipe 33.
[0034] Please refer to this carefully. Figure 1 and Figure 2 The drying chamber 1 is equipped with a drying mechanism 4 on its exterior. The drying mechanism 4 includes a hot air blower 41 fixed on the outer surface of the drying chamber 1 and two filter screens 42 fixed on the inner wall of the drying chamber 1.

[0035] In use, calcium hydroxide is added to the drying chamber 1, and the first motor 210 is controlled to operate. Under the meshing action of the small gear 22 and the large gear 23, the two grinding rollers 21 rotate at different speeds, grinding the calcium hydroxide material. After grinding, the material falls, and under the pushing action of the cylindrical block 27, the connecting frame 26 swings back and forth, driving the connecting rod 28 to swing back and forth via the hinge rod 29. Simultaneously, the two dispersing plates 25 swing back and forth, dispersing the ground material, which continues to fall. At the same time, the hot air blower 41 directs air towards the drying chamber. Hot air is blown into chamber 1 to dry the material. The material enters the conveyor box 31 through the inclined connecting hopper 32, is conveyed upward by the spiral conveyor blades 35, and enters the drying chamber 1 again through the inclined connecting pipe 33, so that the material is ground, broken up and dried again. After the material is completely dried, the second motor 36 is controlled to reverse, so that the spiral conveyor blades 35 reverse, and the material is discharged from the bottom of the conveyor box 31. This device can grind and break up clumps of calcium hydroxide, which is convenient for hot air to dry calcium hydroxide. Compared with directly drying clumps of calcium hydroxide, it can save more time.
