[0018] Example 1

[0019] like Figures 1 to 4 As shown, the utility model proposes a calcined coke screening and grading processing equipment, including a screening box 1, a screening assembly and a driving assembly; a feed pipe 103 is provided at the top of the screening box 1, a box door 101 is hinged at the front end of the screening box 1, and a heat dissipation port 102 is provided on the side wall of the screening box 1, and the heat dissipation port 102 can be connected to an external dust suction mechanism to absorb the dust generated by screening to avoid pollution; the screening assembly is movably arranged at the top of the inside of the screening box 1, and the screening assembly is used to screen the calcined coke material step by step, and the discharge end of the feed pipe 103 extends to the inside of the screening box 1 and corresponds to the screening assembly; the driving assembly is arranged on the side wall of the screening box 1, and the output end of the driving assembly extends to the inside of the screening box 1 and is connected to the screening assembly, and the screening assembly is driven by the driving assembly to reciprocate horizontally along the top of the inside of the screening box 1.

[0020] Furthermore, the screening assembly includes a mounting rod 3 and a screening frame; the mounting rod 3, the top end of which is slidably connected to the top end of the inner part of the screening box 1, and the bottom end of the mounting rod 3 is connected to the driving assembly; there are multiple groups of screening frames, and the multiple groups of screening frames are detachably connected to the mounting rod 3, and the sieve holes on the multiple groups of screening frames on the outer peripheral surface of the mounting rod 3 decrease from top to bottom. A discharge door 504 is provided on the side wall of the screening frame and close to the box door 101, and multiple groups of support seats 301 are evenly arranged on the outer peripheral surface of the mounting rod 3, and the support seats 301 are abutted against the bottom end of the screening frame for supporting the screening frame.

[0021] Furthermore, a limit seat 2 is installed at the top end of the screening box 1, and a sliding channel 202 is provided at the bottom end of the limit seat 2. A slider 201 is connected to the limit seat 2 in a horizontal sliding direction. The slider 201 is slidably connected to the sliding channel 202. The bottom end of the slider 201 extends to the outside of the bottom end of the limit seat 2 and is connected to the screening box 1, so as to keep the mounting rod 3 always sliding in a stable horizontal direction along the limit seat 2 to avoid falling off.

[0022] Furthermore, the projected areas of the multiple groups of screening frames on the outer peripheral surface of the screening box 1 increase from top to bottom, ensuring that the calcined coke material in the upper screening frame is successfully screened into the lower screening frame to avoid missing screening.

[0023] Furthermore, the driving assembly includes a turntable 4 and a slide rod 402; the turntable 4 is driven to rotate by a motor arranged on the outer wall of the screening box 1, and the top edge of the turntable 4 is rotatably connected to the driving rod 401; the slide rod 402 is slidably connected to the screening box 1 and is arranged through the screening box 1, one end of the slide rod 402 is rotatably connected to the driving rod 401, and the other end of the slide rod 402 is connected to the bottom end of the support seat 301.

[0024] In this embodiment, the calcined coke material is poured into the screening box 1 along the feed pipe 103 and finally falls onto a group of screening frames located at the top of the mounting rod 3. The motor drives the turntable 4 to rotate, thereby driving one end of the driving rod 401 to rotate accordingly, and the slide bar 402 is slidably connected to the screening box 1. Then, when the turntable 4 rotates, the driving rod 401 can drive the slide bar 402 to slide back and forth along the horizontal direction of the screening box 1, thereby driving the slider 201 at the top of the mounting rod 3 to reciprocate horizontally along the limit seat 2, thereby driving multiple groups of screening frames to move left and right. The calcined coke material is screened by the reciprocating motion. Since the sieve holes of the multiple groups of screening frames decrease from top to bottom, the calcined coke material can be screened in multiple stages to obtain calcined coke material of different qualities. The material screened by the lowest group of screening frames is discharged along the discharge port at the bottom end of the screening box 1. The box door 101 is opened, and then the discharge door 504 on each group of screening frames is opened to take out the screened material. The screening mechanism vibrates and screens inside the screening box 1 to avoid interfering with the screening box 1, thereby reducing vibration damage to the entire screening box 1 and extending its service life.

[0026] like Figure 4 As shown, the utility model proposes a calcined coke screening and grading processing equipment. Compared with the first embodiment, the screening frame consists of two groups of screening parts 5, and the two groups of screening parts 5 are equipped with connecting seats 501. The two groups of connecting seats 501 can form an annular seat. The two groups of connecting seats 501 are connected to the mounting rod 3 by bolts. The mounting rod 3 is provided with a mounting groove adapted to the bolts. One group of screening parts 5 is rotatably connected to the left and right side walls of each group, and an L-shaped seat 503 is installed on the left and right side walls of the other group of screening parts 5. The other end of the connecting plate 502 is movably connected to the L-shaped seat 503, and the connection between the connecting plate 502 and the L-shaped seat 503 is connected by bolts. A discharge door 504 is provided on the group of screening parts 5 arranged near the box door 101.

[0027] In this embodiment, after using for a period of time, open the box door 101, remove the bolts between the connecting plate 502 and the L-shaped seat 503 on the screening frame, rotate the connecting plate 502 away from the L-shaped seat 503, and then the two groups of screening parts 5 in the screening frame are no longer connected. Then remove the bolts between the connecting seat 501 and the mounting rod 3, and separate the two groups of screening parts 5 from the mounting rod 3 in turn. The screening frame can be disassembled for inspection and maintenance, which provides convenience for use.
