Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1-2 As shown, a ceramic regenerator ball screening device for an aluminum scrap melting furnace includes a sieve hopper 10 for accommodating the ceramic regenerator balls. A screen 11 is provided at the bottom of the sieve hopper 10, and the screen 11 is densely covered with sieve holes 12 corresponding to the size of the ceramic regenerator balls. The diameter of the sieve holes 12 is smaller than the diameter of the ceramic regenerator balls, allowing pulverized or broken ceramic regenerator balls to pass through the sieve holes 12, while intact ceramic regenerator balls are retained on the screen 11 for recycling, thus achieving the screening of the ceramic regenerator balls. Springs 13 are connected to the four corners of the bottom of the sieve hopper 10, allowing the sieve hopper 10 to be elastically connected to a base plate 14. A power device 20 is provided corresponding to the sieve hopper 10, which can drive the sieve hopper 10 to produce a reciprocating oscillating motion to improve the screening efficiency of the sieve hopper 10.

[0021] In a preferred embodiment, the power unit 20 includes a motor 21, which is fixedly connected to the base plate 14. A drive disk 22 is fixedly connected to the output shaft of the motor 21, and an eccentric shaft 23 is eccentrically fixed on the drive disk 22. A connecting shaft 24 is provided on the edge of the screen hopper 10, and a connecting rod 25 is hinged to the connecting shaft 24. The other end of the connecting rod 25 is rotatably connected to the eccentric shaft 23. During screening, the output end of the motor 21 drives the drive disk 22 to rotate, and the eccentric shaft 23 on the drive disk 22 moves circumferentially with the drive disk 22, driving the connecting rod 25 to form a reciprocating pushing and pulling action on the connecting shaft 24 of the screen hopper 10. This drives the screen hopper 10 to produce a reciprocating oscillating motion, causing the ceramic heat storage balls inside the screen hopper 10 to move irregularly, which facilitates the efficient screening of the ceramic heat storage balls. Meanwhile, the spring 13, which is elastically connected between the screen hopper 10 and the bottom plate 14, will undergo a certain elastic deformation under the pushing and pulling action of the connecting rod 25, resulting in the vibration and shaking of the screen hopper 10, which further intensifies the movement of the ceramic heat storage balls inside the screen hopper 10 and improves the screening efficiency.

Specifically, the screen 11 is provided with connecting holes 15 at four corners, the screen box 10 is provided with fixing positions corresponding to the connecting holes 15 at the bottom, and fastening bolts are passed through the connecting holes 15 and fastened on the fixing positions to realize the connection and fixation of the screen 11 and the screen box 10. When screening ceramic heat storage balls of different diameters, the screen 11 can be quickly detached and replaced by rotating the fastening bolts, and the screening operation of ceramic heat storage balls of different sizes can be completed by using the screen 11 with a corresponding aperture, thereby improving the applicability of the screening device.

[0023] Preferably, the screen box 10 is provided with a buffer layer 16 on the inner side, the buffer layer 16 is a strip-shaped structure made of flexible material and is fixedly arranged on the inner wall of the screen box 10, and is used to buffer the impact of the ceramic heat storage balls on the inner wall of the screen box 10, so as to reduce the breakage of the ceramic heat storage balls caused by the strong impact of the ceramic heat storage balls on the inner wall of the screen box 10 during shaking and vibration of the screen box 10, thereby reducing the loss of the ceramic heat storage balls and saving the production cost. The buffer layer 16 can be made of flexible materials such as sponge and polyurethane.

[0024] Preferably, the bottom plate 14 is provided with a material receiving disc 30 corresponding to the bottom of the screen box 10, which is used to collect the waste materials screened out by the screen 11, so as to facilitate the collection of the waste materials.

[0025] Preferably, the screening device further comprises a transfer trolley, which is used to freely move the screening device and facilitate the movement of the screening device to a designated place for screening operation.
