Technical Field

[0001] This utility model relates to the field of calcium oxide production technology, specifically to a drying device for calcium oxide production. Background Technology

[0002] Calcium oxide is an inorganic compound with the chemical formula CaO, commonly known as quicklime. Physically, it is a white powder; impure forms are grayish-white, while those containing impurities are pale yellow or gray. It is hygroscopic, and drying equipment is required during its production to evaporate any residual moisture.

[0003] According to the announcement number CN219178181U, a drying device for calcium oxide production belongs to the field of calcium oxide production technology. It includes a drying drum and a stirring mechanism. The stirring mechanism includes a drying cylinder and two drive motors. The drying cylinder is located at the center of the drying drum.

The two ends of the two rotating rollers penetrate into the drying cylinder and the L-shaped support frames, respectively. A stirring paddle and a transmission wheel are installed at the two ends of the two rotating rollers. A hot air blower is installed on one side of the drying drum, and a conveying pipe connects the hot air blower and the drying drum. This device, through the double-layer design of the drying drum and drying cylinder, prevents the dried object from contacting the calcium oxide, thus preventing over-drying.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1-4 The drying equipment for calcium oxide production shown includes a base 1 with cavities at both ends. A lifting mechanism 2 is installed in the cavity of the base 1, and a support base 3 is fixedly connected to the top of the lifting mechanism 2. A connecting shaft 4 is rotatably connected to the support base 3, and a drying drum 5 is fixedly connected to one end of the connecting shaft 4. A rotating mechanism 6 is installed on the surface of the drying drum 5, and a cleaning component 7 is installed in the inner cavity of the drying drum 5. A limiting groove 8 is opened at the center of the base 1, and a collection box 9 is placed in the limiting groove 8. By installing the lifting mechanism 2 on the base 1 and the support base 3 where the drying drum 5 is installed, the position of the drying drum 5 can be moved up and down, thereby facilitating the placement of drying drums 5 at different depths at the bottom of the drying drum 5 to collect calcium oxide. At the same time, when the drying drum 5 is drying calcium oxide, the cleaning component 7 can clean the inner wall of the drying drum 5, removing calcium oxide adhering to the inner wall of the drying drum 5, avoiding waste of calcium oxide material, and improving the heat transfer of calcium oxide by the drying drum 5.

[0023] The lifting mechanism 2 includes a movable rod 21, with an upper movable seat 22 and a lower movable seat 23 movably connected to its two ends respectively. A mounting plate 24 is fixedly connected to the top of the upper movable seat 22, and a support seat 3 is fixed on the mounting plate 24. The lower movable seat 23 is fixed in the cavity of the base 1. A fixing block 25 is fixedly connected to the movable shaft at the middle connection of the movable rod 21. An electric push rod 26 is installed on the opposite side of the fixing block 25. The electric push rod 26 provides driving force, thereby driving the movable rod 21 by mounting it on the movable shaft of the movable rod 21 through the fixing block 25. Subsequently, through the cooperation of the upper movable seat 22 and the lower movable seat 23, the positions of the two ends of the movable rod 21 can be limited. Therefore, adjusting the position of the movable rod 21 can drive the support seat 3 on the mounting plate 24 to adjust its height, thereby adjusting the position of the drying drum 5 and enhancing the flexibility of the installation of the drying drum 5.

[0024] Positioning rods 10 are fixedly connected to both ends of the mounting plate 24. A fixing frame 11 is provided on the base 1 at the position corresponding to the positioning rods 10. A sliding sleeve that works with the positioning rods 10 is embedded on the top of the fixing frame 11. By setting the positioning rods 10, fixing frame 11 and sliding sleeve together, the support seat 3 can be limited during lifting and adjustment.

[0025] Both ends of the movable shaft of the movable rod 21 are fixedly connected to connecting blocks 12. The surface of the connecting blocks 12 is equipped with balls 13 that fit against the inner wall of the cavity of the base 1. By setting the cooperation between the connecting blocks 12 and the balls 13, the position of the movable rod 21 in the moving position can be limited and slid within the cavity of the base 1.

[0026] The rotating mechanism 6 includes a stepper motor 61, which is mounted on one of the support bases 3 via a fixing plate. The output shaft of the stepper motor 61 is fixedly connected to a rotating shaft 62, one end of which is rotatably connected to another support base 3. A first driving gear 63 is fixedly connected to both ends of the rotating shaft 62, and a first driven gear 64 is fixedly connected to both ends of the drying drum 5. The first driving gear 63 and the first driven gear 64 mesh with each other. By providing driving force through the stepper motor 61, the first driving gear 63 on the rotating shaft 62 is driven to rotate. Subsequently, the first driving gear 63 meshes with the first driven gear 64, thus driving the drying drum 5 to rotate and enhancing the drying effect of the drying drum 5 on calcium oxide.

[0027] The cleaning assembly 7 includes a drive motor 71 mounted on a support base 3 via a fixing plate. The output shaft of the drive motor 71 is fixedly connected to a second drive gear 72. A second driven gear 73 meshes with the surface of the second drive gear 72. A connecting rod 74 is fixedly connected to the inner cavity of the second driven gear 73. One end of the connecting rod 74 passes through one of the connecting shafts 4 and is rotatably connected to the inside of the drying drum 5. Scrapers 75 are fixedly connected at equal intervals on the surface of the connecting rod 74. The side of the scraper 75 closest to the inner wall of the drying drum 5 is beveled and fits against the inner wall of the drying drum 5. Multiple through holes 76 are provided on the scraper 75, and the through holes 76 are arranged in an array. The drive motor 71 provides driving force, and the meshing between the second drive gear 72 and the second driven gear 73 provides power to the connecting rod 74. Subsequently, the connecting rod 74 drives the scraper 75 to rotate on the inner wall of the drying drum 5, which can clean the calcium oxide adhering to the inner wall of the drying drum 5. This not only avoids the waste of calcium oxide, but also enhances the heat transfer effect of the drying drum 5.

[0028] The drying drum 5 includes an inner cylinder 51 and an outer cylinder 52, with a gap between the inner cylinder 51 and the outer cylinder 52. A heating wire 53 is wound around the surface of the inner cylinder 51 and is located in the gap between the inner cylinder 51 and the outer cylinder 52. The inner cylinder 51 allows for easy loading of calcium oxide, and the heat generated by the heating wire 53 provides heat to the calcium oxide in the inner cylinder 51, thus drying the calcium oxide. The outer cylinder 52 provides protection for the heating wire 53 and the inner cylinder 51.

[0029] In practical use, the calcium oxide to be dried is loaded into the drying drum 5 for drying. During the drying process, the stepper motor 61 provides driving force, which drives the first drive gear 63 on the rotating shaft 62 to rotate. Subsequently, the first drive gear 63 meshes with the first driven gear 64, thus driving the drying drum 5 to rotate, enhancing the drying effect of the drying drum 5 on the calcium oxide. At the same time, the inner wall of the drying drum 5 is driven by the drive motor 71, and the second drive gear 72 meshes with the second driven gear 73, which provides power to the connecting rod 74. Subsequently, the connecting rod 74 drives the scraper 75 to rotate on the inner wall of the drying drum 5, which can clean the calcium oxide adhering to the inner wall of the drying drum 5. This avoids the waste of calcium oxide and enhances the heat transfer effect of the drying drum 5. After drying, the collection box 9 is placed below the drying drum 5. The staff can adjust the height of the drying drum 5 according to the depth of the collection box 9. The electric push rod 26 provides driving force, which is then installed on the movable shaft of the movable rod 21 through the fixing block 25, thus providing driving force to the movable rod 21. Subsequently, through the cooperation of the upper movable seat 22 and the lower movable seat 23, the positions of both ends of the movable rod 21 can be limited. Therefore, the position adjustment of the movable rod 21 can drive the support seat 3 on the mounting plate 24 to adjust the height, thereby adjusting the position of the drying drum 5 and enhancing the flexibility of the installation position of the drying drum 5.
