It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: a pressing device for a cyclone classifier, including a screening box 1. Two screening cavities 2 are provided on the surface of the screening box 1. Support frames 3 are fixedly installed on the inner walls of the two screening cavities 2. A fine screen 7 and a coarse screen 6 are respectively placed on the surface of the support frame 3. The fine screen 7 and the coarse screen 6 are both inclined.
[0024] Next, specifically describe the specific settings and functions of its auxiliary device 4 and extension device 5.
[0025] In this embodiment: Auxiliary devices 4 are provided on both side surfaces of the screening box 1. The auxiliary device 4 includes four U-shaped plates 41. Every two of the four U-shaped plates 41 are fixedly installed on both side surfaces of the screening box 1. A threaded rod 42 is rotatably connected between the inner walls at both ends of the U-shaped plate 41. A motor 43 is fixedly installed on the top surface of the U-shaped plate 41. The output end of the motor 43 is fixedly connected to the threaded rod 42.
[0026] In this embodiment: The setting of the motor 43 plays an effect of driving the threaded rod 42 to rotate.
[0027] Specifically, a vertical groove 44 is provided on the inner wall surface of the vertical end of the U-shaped plate 41. A long strip plate 45 is threadedly connected to the surface of the threaded rod 42.
[0028] In this embodiment: The setting of the threaded rod 42 plays an effect of driving the long strip plate 45 to move inside the vertical groove 44.
[0029] Specifically, a support rod 46 is fixedly installed on the bottom surface of the long strip plate 45. One end of the support rod 46 away from the long strip plate 45 is fixedly installed with a pressing plate 47. The setting of the pressing plate 47 plays an effect of pressing and fixing the coarse screen 6 and the fine screen 7 on the surface of the support frame 3.
[0030] In this embodiment: An extension device 5 is provided on the top surface of the screening box 1. The extension device 5 includes a chute 501 which is opened on the top surface of the screening box 1. Two sliders 502 are slidably connected inside the chute 501. Two support plates 503 are fixedly installed on the top surface of the screening box 1. Electric telescopic rods 504 are fixedly installed on the surfaces of the two support plates 503. The output ends of the electric telescopic rods 504 are fixedly connected to the sliders 502. When it is necessary to extend the time for the raw material to stay on the surface of the fine screen 7, first start the two electric telescopic rods 504 simultaneously. The two electric telescopic rods 504 start to drive the two sliders 502 to move away from each other inside the chute 501. The movement of the two sliders 502 away from each other inside the chute 501 drives the hinge plate 505 to move. The movement of the hinge plate 505 pulls the strip plate 506 to move downward. The downward movement of the strip plate 506 drives the round rod 507 to move downward. The downward movement of the round rod 507 drives the first extension plate 508 to move downward. The downward movement of the first extension plate 508 drives the connecting rod 509 and the second extension plate 510 to move downward. When the positions of the first extension plate 508 and the second extension plate 510 moving downward fit on the surface of the fine screen 7, just turn off the electric telescopic rods 504. Then the staff starts the classifier. The classifier causes the screening box 1 to vibrate. The raw material falls from the hopper onto the fine screen 7. The raw material passes through the fine screen 7 and the coarse screen 6 in sequence through vibration, realizing the screening of different specifications. At the same time, the first extension plate 508 and the second extension plate 510 can be used to increase the movement path of the raw material and extend the time for the raw material to be screened. Through the cooperation of the above structures, the time for the raw material to stay on the fine screen 7 is increased, thereby increasing the screening effect of the device.
[0031] Specifically, one end surface of the slider 502 away from the chute 501 is hinged with a hinge plate 505, and one end of the hinge plate 505 away from the slider 502 is hinged with a strip plate 506.
[0032] In this embodiment: The setting of the hinge plate 505 plays an effect of driving the strip plate 506 to move.
[0033] Specifically, a round rod 507 is fixedly installed on the bottom surface of the strip plate 506. One end of the round rod 507 away from the strip plate 506 is fixedly installed with a first extension plate 508. A connecting rod 509 is fixedly installed on the side surface of the first extension plate 508. One end of the connecting rod 509 away from the first extension plate 508 is fixedly installed with a second extension plate 510.
[0034] In this embodiment: The settings of the first extension plate 508 and the second extension plate 510 play an effect of increasing the staying time of the raw material on the surface of the fine screen 7.
[0035] Working principle: By setting the auxiliary device 4, when it is necessary to press and fix the fine screen 7 and the coarse screen 6 on the surface of the support frame 3, first place the fine screen 7 and the coarse screen 6 on the surface of the support frame 3, and then start the motor 43. The start of the motor 43 drives the threaded rod 42 to rotate. The rotation of the threaded rod 42 drives the long strip plate 45 to move downward inside the vertical groove 44. The downward movement of the long strip plate 45 inside the vertical groove 44 drives the support rod 46 to move downward. The downward movement of the support rod 46 drives the pressing plate 47 to move downward. When the position of the pressing plate 47 moving downward fits the surface of the coarse screen 6 or the fine screen 7, turn off the motor 43. Through the cooperation of the above structure, the pressing plate 47 can press and fix the coarse screen 6 or the fine screen 7 on the surface of the support frame 3, enabling the staff to quickly replace different specifications of screens at any time. When it is necessary to extend the residence time of the raw material on the surface of the fine screen 7, first start two electric telescopic rods 504 simultaneously. The start of the two electric telescopic rods 504 drives the two sliders 502 to move away from each other inside the chute 501. The movement of the two sliders 502 away from each other inside the chute 501 drives the hinge plate 505 to move. The movement of the hinge plate 505 pulls the strip plate 506 to move downward. The downward movement of the strip plate 506 drives the round rod 507 to move downward. The downward movement of the round rod 507 drives the first extension plate 508 to move downward. The downward movement of the first extension plate 508 drives the connecting rod 509 and the second extension plate 510 to move downward. When the positions of the first extension plate 508 and the second extension plate 510 moving downward fit the surface of the fine screen 7, turn off the electric telescopic rod 504. Then the staff starts the classifier. The classifier causes the screening box 1 to vibrate. The raw material falls from the hopper onto the fine screen 7. The raw material passes through the fine screen 7 and the coarse screen 6 in sequence through vibration, realizing the screening of different specifications. At the same time, the first extension plate 508 and the second extension plate 510 can be used to increase the movement path of the raw material, extending the screening time of the raw material. Through the cooperation of the above structure, the residence time of the raw material on the fine screen 7 is increased, thereby enhancing the screening effect of the device.
