Description

Technical Field

[0001] This utility model belongs to the field of anti-caking in catalyst drying treatment, and specifically relates to an anti-caking device for drying hydrated catalysts. Background Technology

[0002] In the chemical production field, hydrated catalysts are key reaction promoters, and their drying process is crucial for ensuring catalytic activity and subsequent performance. However, during the drying process, hydrated catalysts are prone to agglomeration due to factors such as moisture adhesion between material particles, surface tension, and uneven drying rates. Agglomerated hydrated catalysts adversely affect the stability of subsequent chemical production processes and product quality.

[0003] Currently, most industrial drying and anti-caking devices use a single fixed roller structure, which uses rotating rake teeth to tumble and crush the material. This single fixed roller design means that the purchased anti-caking equipment cannot be adapted to the effective working width of the conveyor belt, resulting in ineffective crushing of materials at the edges.

[0004] Therefore, we propose an anti-caking device for drying hydrated catalysts to solve the above problems. Utility Model Content

[0005] The design of a single fixed roller body causes the purchased anti-caking equipment to be unable to be adaptively adjusted according to the effective working width of the conveyor belt, resulting in the ineffective crushing of edge materials. This utility model provides an anti-caking device for drying hydrated catalysts.

[0006] The solution adopted by this utility model to solve its technical problem is: an anti-caking device for drying hydrated catalyst, including a U-shaped frame, a drive motor, a transmission component, a rotating shaft one and a rotating shaft two, with bearing seats fitted at both ends of the rotating shaft one and the rotating shaft two, and the four bearing seats are installed in pairs at the two bottom ends of the U-shaped frame. A fixed roller is fitted in the middle section of the first rotating shaft, and two movable rollers are fitted in the left and right sections of the second rotating shaft. The movable rollers can slide laterally along the second rotating shaft. Two sets of fixing parts are provided on the second rotating shaft to fix the position of the movable rollers. Multiple rake teeth are welded and fixed to the outer surfaces of both the fixed roller and the two movable rollers; The drive motor is mounted on the top of the U-shaped frame and is connected to shaft one and shaft two via a transmission assembly to drive shaft one and shaft two to rotate.

[0007] Preferably, two L-shaped support legs are welded and fixed at the top left and right of the U-shaped frame, and at least two bolt holes are opened at the bottom of the L-shaped support legs.

[0008] Preferably, the outer surface of the second rotating shaft is provided with external threads.

[0009] Preferably, a set of the fixing components includes two nuts, which are respectively disposed at the left and right ends of the movable roller and are threadedly connected to the movable roller.

[0010] Preferably, the transmission assembly includes a transmission box and three synchronous pulleys. The transmission box is fixedly installed on the left side of the U-shaped frame. The left ends of the output shaft of the drive motor, shaft one, and shaft two extend into the transmission box. The three synchronous pulleys are respectively mounted on the output shaft of the drive motor, shaft one, and shaft two. The three synchronous pulleys are connected by the same synchronous belt.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model sets up a fixed roller and two movable rollers that can slide laterally. By rotating the nuts one by one, the distance between the two movable rollers can be flexibly adjusted according to the actual working width of the conveyor belt. The fixed roller and the two movable rollers form an interlaced crushing zone, so that the multiple rake teeth can evenly turn over and crush the hydrated catalyst in the entire area of ​​the conveyor belt when rotating, thereby solving the problem that the edge materials cannot be effectively crushed.

[0012] 2. This utility model uses two nuts to clamp and fix the movable roller, which not only ensures transmission stability but also facilitates adjustment of the position of the movable roller. It has a simple structure and is easy to use. Attached Figure Description

Two L-shaped support legs 3 are welded and fixed to the top left and right of the top of the U-shaped frame 1, respectively. At least two bolt holes 31 are opened at the bottom of the L-shaped support legs 3. By passing bolts through the bolt holes 31, the L-shaped support legs 3 can be fixed to the frame of the conveyor.

[0017] Bearing seats 2 are fitted at both ends of the first rotating shaft 51 and the second rotating shaft 53. The four bearing seats 2 are installed in pairs at the two bottom ends of the U-shaped frame 1 to ensure the stability of the first rotating shaft 51 and the second rotating shaft 53 during rotation.

[0018] A fixed roller 52 is fitted in the middle section of the first rotating shaft 51, and two movable rollers 55 are fitted in the left and right sections of the second rotating shaft 53 respectively. The movable rollers 55 can slide laterally along the second rotating shaft 53, and the distance between the two movable rollers 55 can be flexibly adjusted according to the actual working width of the conveyor belt. The fixed roller 52 and the two movable rollers 55 form an alternating crushing zone.

[0019] The outer surface of the second rotating shaft 53 is provided with an external thread 54. The second rotating shaft 53 is provided with two sets of fixing parts for fixing the position of the movable roller 55. Each set of fixing parts includes two nuts 56. The two nuts 56 are respectively located at the left and right ends of the movable roller 55 and are threadedly connected to the movable roller 55. The movable roller 55 is fixed by clamping it with the two nuts 56, which not only ensures the transmission stability but also facilitates the adjustment of the position of the movable roller 55. The structure is simple and easy to use.

[0020] Multiple rake teeth 57 are welded and fixed to the outer surfaces of the fixed roller 52 and the two movable rollers 55.

The three synchronous pulleys 43 are respectively mounted on the output shaft of the drive motor 42, the first rotating shaft 51, and the second rotating shaft 53. The three synchronous pulleys 43 are connected by the same synchronous belt 44. By starting the drive motor 42, the first rotating shaft 51 and the second rotating shaft 53 are driven to rotate synchronously under the action of the three synchronous pulleys 43 and the synchronous belt 44, so that the multiple rake teeth 57 rotate to turn over and crush the hydrated catalyst in the entire area of ​​the conveyor belt.

[0022] In practical use, the anti-caking device for drying hydrated catalyst of this utility model first fixes the L-shaped support feet 3 on both sides to the conveyor frame with bolts to ensure the stability of the device; Next, based on the actual working width of the conveyor belt, slide the two movable rollers 55 on the second sliding shaft 53 to make the distance between the two movable rollers 55 match the width of the conveyor belt. Then rotate the nuts 56 one by one so that the two nuts 56 in the same group clamp and fix one movable roller 55, ensuring that the two fixed rollers 52 are fixed and the transmission is stable. When the power is turned on, the drive motor 42 is started. Under the action of the three synchronous pulleys 43 and the synchronous belt 44, the rotating shaft 1 51, rotating shaft 2 53, fixed roller 52 and two movable rollers 55 are driven to rotate synchronously. The rake teeth 57 on the fixed roller 52 and the two movable rollers 55 form an interlaced crushing zone, which turns and crushes the hydrated catalyst on the conveyor belt.
