Description

Technical Field

[0001] This utility model relates to the field of industrial chemical production technology, specifically to a calcium chloride particle drying device. Background Technology

[0002] Calcium chloride is a chemical substance composed of chlorine and calcium elements. It is a common industrial chemical with the chemical formula CaCl2 and has a slightly bitter taste. It is a typical ionic halide, appearing as white, hard fragments or granules at room temperature. Common applications include desiccants, refrigerants, de-icing agents, building antifreeze agents, and lubricant additives. According to product standards, commonly used calcium chloride products are anhydrous calcium chloride (CaCl2) and calcium chloride dihydrate (CaCl2·2H2O).

[0003] Traditional hot air drying of calcium chloride relies on high-temperature air, resulting in low thermal energy utilization. A large amount of heat is lost with the exhaust gas. Some technologies require multiple heating cycles to maintain the drying temperature. Since only one side of the calcium chloride particles can be heated, the drying is uneven, reducing the drying efficiency. Furthermore, conventional technologies only perform heating treatment, resulting in a slow drying process. During the drying process, the particle surface clumps together, requiring secondary crushing, which increases costs and presents various problems. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model patent designs a calcium chloride particle drying device.

[0005] The technical solution adopted by this utility model is as follows: the drying equipment includes a drying box, a hot air generating device is provided on the upper inner side of the drying box, and a placement mesh cylinder is rotatably connected to the lower part.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the present invention will be clearly and completely described. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 , 2 As shown in Figures 3 and 4, this utility model patent designs an embodiment of a calcium chloride granule drying device. In this embodiment, the drying device includes a drying chamber 1. A hot air generator is installed on the upper inner side of the drying chamber 1, and a placement screen cylinder 4 is rotatably connected to the lower part. The placement screen cylinder 4 has a material inlet for loading and unloading calcium chloride granules. A lockable opening and closing cover 9 is provided at the material inlet. The hot air generator includes multiple fans and a heating coil 26. The multiple fans are evenly distributed on the top inner side of the drying chamber 1. The heating coil 26 is located between the fans and the placement screen cylinder 4. A layer of air distribution mesh 13 is also provided between the lower side of the heating coil 26 and the placement screen cylinder 4. An air inlet window is opened on the top of the drying chamber 1, and an air inlet filter 21 is installed at the window. A door 27 is hinged to the front, allowing it to be opened during loading and unloading. An air outlet is provided on the back, and the outlet pipe connects to an existing filtration and dust removal device.

[0021] A drive motor 2 is fixedly installed on the left side of the exterior of the drying oven 1. The output shaft of the drive motor 2 extends into the interior of the oven and is fixedly connected to a transmission shaft 3. The right end of the transmission shaft 3 is rotatably connected to the right side of the oven body via a bearing. The transmission shaft 3 passes through the axis of the mesh cylinder 4. The two ends of the mesh cylinder 4 are slidably connected to the transmission shaft 3 via sealing sleeves. A cleaning mechanism can be installed on the inner end of the sealing sleeves on both sides to prevent calcium chloride particles falling on the transmission shaft 3 from obstructing the movement of the sealing sleeves. A fixed turntable 5 is fixedly connected to the right end of the transmission shaft 3. Two guide rods 6 are symmetrically connected to the surface of the fixed turntable 5 facing the mesh cylinder 4, and the guide rods 6 are arranged along the transmission shaft axis. Correspondingly, two guide cylinders 7 are axially arranged on the right end face of the mesh cylinder 4. Two guide rods 6 are slidably inserted into the two guide cylinders 7 respectively. A first spring 8 is sleeved on the outside of the guide rod 6. The two ends of the first spring 8 abut against the end face of the fixed turntable 5 and the mesh cylinder 4 respectively. A sealing sleeve is sleeved on the outside of the guide cylinder 7 and the guide rod 6 to prevent dust from entering the guide cylinder 7 and affecting the relative movement with the guide rod 6. After the drive motor 2 starts, it drives the fixed turntable 5 to rotate synchronously through the transmission shaft 3, thereby driving the mesh cylinder 4 to rotate synchronously through the guide rods 6, realizing the turning of calcium chloride particles in the mesh cylinder.

[0022] Inside the drying oven 1, on the left side, a swashplate 10 is fixedly connected via a mounting rod 12. The swashplate 10 is coaxially mounted with the drive shaft 3, which passes through the axis of the swashplate 10 and is rotatably connected to it via a sealed bearing. A support crossbar 11 extends axially from the left end face of the placement mesh cylinder 4, and a roller at the end of the support crossbar 11 abuts against the surface of the swashplate 10. During the rotation of the placement mesh cylinder 4, the roller at the end of the support crossbar 11 moves along the surface of the swashplate 10, pushing the placement mesh cylinder 4 to slide axially under the action of the swashplate 10, and compressing the first spring 8 to deform. Thus, under the combined action of the swashplate 10 and the first spring 8, the placement mesh cylinder 4 reciprocates axially, achieving multi-directional tumbling of the calcium chloride particles inside the mesh cylinder.

[0023] A support cylinder 19 is fixedly installed on the top left side of the inner side of the drying oven 1. A movable rack 18 is slidably connected in the support cylinder 19, and a second spring 20 is installed between the bottom of the support cylinder 19 and the left end face of the movable rack 18. A roller is installed on the right end of the movable rack 18. To ensure the stability of the movable rack 18, a support mechanism is also installed on the top right side of the oven body and slidably connected to the movable rack 18. A convex turntable 17 is rotatably connected to the top right side of the inner side of the drying oven 1. The roller on the right end of the movable rack 18 abuts against the surface of the convex turntable 17. When the convex turntable 17 rotates, the roller on the movable rack 18 rolls on the turntable, thereby pushing the movable rack 18 to the left, compressing the second spring 20 to deform. Under the combined action of the convex turntable 17 and the second spring 20, the axial reciprocating motion of the movable rack 18 is realized.

[0024] The multiple fans inside the drying chamber 1 are all composed of a blower 24 and a blower blade 25. The blower 24 is fixed on the base. The upper side of the base is an arc-shaped gear part 23. Its center is rotatably connected to the support plate on the top of the chamber through a rotating shaft 22, so that the base can swing left and right with the rotating shaft 22 as the center. The gear part 23 is meshed with the moving rack 18, and the fan swings back and forth under the reciprocating movement of the moving rack 18.

[0025] A second pulley 16 is provided at the bottom of the convex turntable 17. Correspondingly, a first pulley 14 is fixedly connected to the right end of the drive shaft 3. The first pulley 14 and the second pulley 16 are connected by a drive belt 15, thereby realizing the synchronous rotation of the cam disc 17 driven by the drive shaft 3. In practical applications, a partition plate is required inside the drying chamber 1 between the first pulley 14 and the fixed turntable 5. The top of the partition plate abuts against the air distribution mesh 13, and the bottom abuts against the chamber body. A sealed bearing is installed between the partition plate and the drive shaft 3 for rotational connection, separating one side of the first pulley 14 to prevent dust generated during the drying of materials in the mesh cylinder 4 from affecting the operation of the first pulley 14.

[0026] In application of the calcium chloride granule drying equipment disclosed in this utility model patent, the door 27 and the opening / closing cover 9 are opened, and the calcium chloride granules are placed into the placement mesh cylinder 4. The opening / closing cover 9 and the door 27 are closed, and the drive motor 2 is turned on. The drive shaft 3 rotates, driving the fixed turntable 5 to rotate. The fixed turntable 5 drives the placement mesh cylinder 4 to rotate through the guide rod 6 and the guide cylinder 7, realizing the turning of the calcium chloride granules in the mesh cylinder. The fan 24 and the heating coil 26 are turned on to start blowing air and heating the placement mesh cylinder 4. During the rotation of the placement mesh cylinder 4, under the combined action of the inclined plate 10 and the first spring 8, it can move back and forth along the axial direction, realizing the multi-directional turning of the calcium chloride granules. During the rotation of the drive shaft 3, the cam plate 7 is driven to rotate synchronously through the first pulley 14, the drive belt 15 and the second pulley 16. The fan also swings back and forth under the combined action of the moving rack 18, the cam plate 7 and the second spring 20, adjusting the blowing direction, expanding the drying area and improving the drying efficiency.

[0027] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention.
