Description

Technical Field

[0001] The utility model relates to the technical field of material screening, in particular to a screening device. Background Art

[0002] As a key equipment in the production of battery materials, the vibrating screen can effectively control the particle size of the product and can screen out foreign matter in the material. Foreign matter and coarse particles are discharged from the slag discharge port of the upper screen frame, and normal materials are discharged from the discharge port of the lower screen frame. During operation, in order to prevent normal materials from being discharged from the slag discharge port, the slag discharge port is usually in a closed state. After running for a period of time, the slag discharge port is manually opened to clean the screened material. This is not only time-consuming and labor-intensive, but also difficult to control the time of opening the slag discharge port for cleaning. Once the running time is too long, the increase in screened material will cause wear and even damage to the screen, resulting in quality accidents. Utility Model Content

[0006] As a further improvement of the above technical solution:

[0007] The opening and closing mechanism includes a baffle and a driver. The driver is arranged on the slag discharge pipe. One end of the baffle is hinged to the inner cavity edge of the cavity, and the other end is driven by the driver to close or open the slag discharge pipe.

[0008] The driver drives the baffle to rotate around the hinge point toward the outside of the inner cavity of the cavity to the slag discharge pipe to open the slag discharge pipe, and the driver drives the baffle to rotate around the hinge point from the inside of the slag discharge pipe to fit with the inner cavity of the cavity to close the slag discharge pipe.

[0013] Compared with the prior art, the advantages of the utility model are:

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Embodiment 1:

[0023] like Figures 1 to 3As shown, the first embodiment of the screening device of the utility model comprises a frame 1 and a cavity 2 mounted on the frame 1, a feeder 3 is connected to the upper part of the cavity 2, a vibrating screen 4 is arranged in the inner cavity of the cavity 2, a slag discharge pipe 21 is arranged in the inner cavity above the vibrating screen 4, a discharge pipe 22 is arranged in the inner cavity below the vibrating screen 4, an opening and closing mechanism 5 is arranged between the discharge pipe 21 and the inner cavity, and a monitoring mechanism 6 for measuring the material on the vibrating screen 4 is arranged on the frame 1. When in use, the discharge pipe 21 is closed by the opening and closing mechanism 5 to prevent normal materials from being discharged from the discharge pipe 21, and the material on the vibrating screen 4 is measured by the monitoring mechanism 6, and the single chip microcomputer can be set to control according to the measurement result. When the measurement data reaches the set value, the feeder 3 stops feeding, and then the opening and closing mechanism 5 is controlled to open the discharge pipe 21 to discharge slag, and then the opening and closing mechanism 5 continues to close the discharge pipe 21 to perform feeding and screening work, which is simple, ingeniously designed, does not require manual intervention, and saves time and effort.

[0024] In this embodiment, the opening and closing mechanism 5 includes a baffle 51 and a driver 52. The driver 52 is arranged on the slag discharge pipe 21. One end of the baffle 51 is hinged to the inner cavity edge of the cavity 2, and the other end is driven by the driver 52 to close or open the slag discharge pipe 21. The result is simple and reliable.

[0025] In this embodiment, the driver 52 drives the baffle 51 to rotate around the hinge point toward the outside of the inner cavity of the cavity 2 to the inside of the slag discharge pipe 21 to open the slag discharge pipe 21, and the driver 52 drives the baffle 51 to rotate around the hinge point from the inside of the slag discharge pipe 21 to fit with the inner cavity of the cavity 2 to close the slag discharge pipe 21. In this structure, the baffle 51 rotates toward the outside of the inner cavity of the cavity 2 to open, so as to prevent the baffle 51 from scratching the vibrating screen 4 in the inner cavity.

[0026] In this embodiment, the driver 52 is configured as a cylinder, and its driving is stable and reliable.

[0027] In this embodiment, the monitoring mechanism 6 includes a weighing device, which is connected to the vibrating screen 4 and performs inductive weighing on the material on the vibrating screen 4.

If the feeder 3 feeds normally and the weighing weight does not increase, it means that the vibrating screen is damaged.

[0028] In this embodiment, a cone 7 for facilitating material discharge is provided in the inner cavity of the cavity 2 at the lower part of the vibrating screen 4. In this structure, the cone 7 is provided in the inner cavity to facilitate the discharge of the material and prevent the material from accumulating in the inner cavity.
