DETAILED DESCRIPTION
[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0020] Example:
[0021] Reference Figures 1 to 3 The utility model discloses a catalyst drying device, comprising a drying box 1 and a hot air furnace 2 located on one side of the drying box 1, a blower 3 is fixedly connected to the side wall of the hot air furnace 2, an input end of the blower 3 is connected to an air outlet of the hot air furnace 2, and an output end of the blower 3 is connected to the lower half of the drying box 1.
[0022] A driving part 4 is provided in the drying box 1, and two discharge parts 5 are provided in the drying box 1 in a mirror image about the center line of the drying box 1. A guide frame 6 is fixedly sleeved on the lower half of the outer peripheral side of the drying box 1, and a collecting box 7 is placed on the lower half of one side of the drying box 1. The side wall of the guide frame 6 is opened directly above the collecting box 7, and the guide frame 6 is gradually lowered from the side away from the collecting box 7 to the side close to the collecting box 7.
[0023] In this embodiment, an exhaust port is provided at the top of the drying box 1. When the blower 3 is working, the hot air generated by the hot air furnace 2 is transported into the drying box 1. The hot air moves from bottom to top in the drying box 1 to dry the catalyst, and then is discharged from the drying box 1 through the exhaust port on the top.
[0024] Guide frame 6 Figure 1 As shown, the catalysts that fall onto the top of the guide frame 6 can slide into the collection box 7 under the action of gravity, thereby completing the collection of the catalysts.
[0025] In a further preferred embodiment of the present invention, Figure 2 As shown, the driving part 4 includes a bracket fixedly connected to the bottom of the drying box 1, a motor 41 is fixedly connected to the top of the bracket, and a driving rod 42 is transmission-connected to the output end of the motor 41. The driving rod 42 rotates through the bottom wall of the drying box 1 and is rotationally connected to the top wall of the drying box 1.
[0026] In this embodiment, the motor 41 drives the driving rod 42 to rotate, thereby driving the discharging part 5 to operate.
[0027] In a further preferred embodiment of the present invention, Figure 2 As shown, the discharge part 5 includes two screws 51 that are horizontally rotated and penetrate the side wall of the drying box 1, and the screws 51 are transmission-connected to the driving rod 42 through the transmission part 52. The top wall and the bottom wall of the drying box 1 are fixedly connected with support frames 53, and the screws 51 rotate through the corresponding support frames 53, and a placement part 54 is provided between the two corresponding screws 51.
[0028] In this embodiment, the driving rod 42 drives the lead screw 51 to rotate through the transmission part 52. The support frame 53 supports and limits the lead screw 51 to prevent the lead screw 51 from tilting.
[0029] In a further preferred embodiment of the present invention, Figure 2 As shown, the transmission part 52 includes two driving bevel gears fixedly sleeved on the outer circumference of the driving rod 42, and one end of the lead screw 51 close to the driving rod 42 is fixedly connected to a driven bevel gear, and the corresponding driven bevel gear is meshed with the corresponding driving bevel gear.
[0030] In this embodiment, the driving rod 42 rotates to drive the driving bevel gear to rotate, and the driving bevel gear drives the driven bevel gear to rotate, thereby driving the lead screw 51 to rotate.
[0031] In a further preferred embodiment of the present invention, Figure 1 As shown, the placement portion 54 includes a screw plate 541, which is threadedly connected to the outer circumference of the corresponding two screws 51, and a plurality of placement plates 542 are hinged on one side of the screw plate 541. The bottom surface of the placement plate 542 is hollowed out, and the catalyst is placed on the top of the placement plate 542.
[0032] A discharge portion 543 is provided below the placement plate 542. A side opening 544 is provided on the side wall of the drying box 1 corresponding to the placement plate 542. A baffle 545 is threadedly connected to the outer circumference of the two lead screws 51 located outside the drying box 1. The baffle 545 is attached to the outer circumference of the drying box 1 and shields the corresponding side openings 544.
[0033] In this embodiment, when the lead screw 51 rotates, it drives the screw plate 541 to move toward the side opening 544, and the screw plate 541 drives the placement plate 542, the discharge part 543 and the catalyst to move. When the lead screw 51 rotates, it drives the baffle 545 to move away from the drying box 1, so that the side opening 544 is exposed.
[0034] In a further preferred embodiment of the present invention, Figure 3As shown, the unloading part 543 includes a rotating plate 5431 hinged to one side of the screw plate 541, and the rotating plate 5431 is located below the corresponding placement plate 542. A spring 5432 is fixedly connected between the rotating plate 5431 and the corresponding screw plate 541, and a connecting rod 5433 is hinged at the top of the rotating plate 5431, and the top of the connecting rod 5433 is hinged to the bottom of the corresponding placement plate 542.
[0035] In this embodiment, when the rotating plate 5431 is not in contact with the inner wall of the drying box 1, supported by the restoring force of the spring 5432, the side of the placement plate 542 away from the screw plate 541 will not tilt downward, so the catalyst on the placement plate 542 will not slide off.
[0036] When the screw plate 541 moves, it drives the placement plate 542 to pass through the side opening 544, so that the catalyst moves to the outside of the drying box 1. Then the screw plate 541 continues to move, driving the rotating plate 5431 to contact the inner wall of the drying box 1, and the rotating plate 5431 rotates, driving the connecting rod 5433 to move, and the connecting rod 5433 drives the placement plate 542 to rotate downward, so that the catalyst on the top of the placement plate 542 slides into the guide frame 6 under the action of gravity.
[0037] The implementation principle of the above embodiment is:
[0038] When the blower 3 is working, the hot air generated by the hot air furnace 2 is transported to the drying box 1. The hot air moves from bottom to top in the drying box 1 to dry the catalyst.
[0039] When the catalyst is dried, the motor 41 drives the driving rod 42 to rotate, and the driving rod 42 drives each screw 51 to rotate through the transmission part 52. The rotation of the screw 51 drives the baffle 545 to move away from the drying box 1, so that the side opening 544 is exposed; at the same time, the screw 51 drives the screw plate 541 to move toward the side opening 544, and the screw plate 541 drives the placement plate 542 to move, and the placement plate 542 passes through the side opening 544, so that the catalyst moves to the outside of the drying box 1.
[0040] Then the motor 41 continues to work, the screw plate 541 drives the rotating plate 5431 to contact the inner wall of the drying box 1, the rotating plate 5431 rotates, driving the connecting rod 5433 to move, and the connecting rod 5433 drives the placement plate 542 to rotate downward, so that the catalyst on the top of the placement plate 542 slides into the guide frame 6 under the action of gravity, and the catalyst that falls on the top of the guide frame 6 can slide into the collection box 7 under the action of gravity to complete the collection of the catalyst.
[0041] Then the motor 41 rotates in the opposite direction, and when the rotating plate 5431 just stops contacting the inner wall of the drying box 1, the operator can re-place the catalyst on the top of the placement plate 542, and then the motor 41 continues to work, driving the placement plate 542 and the catalyst into the drying box 1, and the baffle 545 fits against the outer wall of the drying box 1 again to cover the side opening 544.
[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
