Description

Technical Field

[0001] The utility model belongs to the technical field of coke classification, and in particular relates to a multi-stage sorting device used for coke production. Background Art

[0002] Coke is a solid fuel that is hard, porous, high in calorific value, and is made by high-temperature dry distillation of coal. It is mostly used for ironmaking. Coke is usually divided into metallurgical coke, gasification coke, and calcium carbide coke according to its use. Cokes of different sizes are used in different places, so before using coke, it needs to be sorted in multiple levels. In the process of grading coke, coke is usually divided into four grades according to its size. The grading of coke depends on the size of the coke, which is usually divided into grades with a size greater than 40mm, 25-40mm, 10-25mm, and less than 10mm.

[0003] In the prior art, when coke is graded, the coke is usually discharged after the coke grading is completed. In this method, grading a large amount of coke at one time is likely to lead to insufficient coke grading, and small pieces of coke are easily mixed in large pieces of coke. When a small amount of coke is graded at one time, the coke can be fully graded, but this method requires workers to perform multiple operations, and the grading efficiency is low.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-3As shown, a multi-stage sorting device for coke production comprises a grading barrel 1 arranged obliquely, three screening plates 2 with different apertures are arranged in sequence above the bottom wall of the grading barrel 1, four first discharge ports 3 are arranged on the side of the grading barrel 1 opposite to the ground, the lower end surface of the lowest first discharge port 3 is flush with the bottom of the grading barrel 1, and the lower end surfaces of the three upper first discharge ports 3 are flush with the upper surfaces of the corresponding screening plates 2, a rotating shaft 4 is rotatably connected to the middle of the three screening plates 2, and a driving device for driving the rotating shaft 4 is installed on the outer side of the grading barrel 1. The rotating shaft 4 is provided with four groups of rotating parts 42 in sequence, and the four groups of rotating parts 42 are respectively located on the upper sides of the grading barrel 1 and the three screening plates 2. The outer side of the grading barrel 1 is rotatably connected with a cylinder 5, and the cylinder 5 is provided with three second discharge ports 51 in sequence. The upper and lower surfaces of the three second discharge ports 51 are flush with the upper and lower surfaces of the three first discharge ports 3 located above the grading barrel 1. The cylinder 5 is connected with a transmission assembly 52. ​​The upper outer side of the cylinder 5 is rotatably connected with a support ring 6 through a bearing ring. The lower side of the grading barrel 1 and the support ring 6 are provided with a support part 61.

[0024] With the technical solution of this embodiment, the coke enters from the entrance above the screening plate 2. Since the coke has different block diameters, when the drum 5 blocks the first discharge port 3, the coke smaller than the aperture of the screening plate 2 falls under the action of its own gravity, and the rotating shaft 4 drives the rotating member 42 to rotate the coke, so that the coke is fully screened. It should be noted that a small amount of coke is screened at a time. After the screening is completed, the drum 5 is controlled to rotate by the transmission assembly 52, so that the second discharge port 51 of the drum 5 is aligned with the first discharge port 3 of the grading barrel 1. The coke cannot pass through the screening plate 2, and the coke falls out of the second discharge port 51 under the action of gravity. Since the smallest piece of coke does not need to be screened again, the first discharge port 3 located at the bottom directly discharges the smallest piece of coke. A collecting device is provided below the second discharge port 51 to collect the sorted coke separately. The support member 61 is used to support the inclined grading barrel 1, and the support ring 6 is rotatably connected to the cylinder 5. When the cylinder 5 rotates, the support ring 6 can support the cylinder 5, and the bearing ring is used to keep the distance between the support ring 6 and the cylinder 5 unchanged.

[0025] Reference Figure 3 : The driving member 41 is a motor.

[0026] In this embodiment, the motor output shaft is transmission-connected to the rotating shaft 4 to drive the rotating shaft 4 to rotate.

[0027] Reference Figure 3 : The aperture sizes of the three screening plates 2 are 40mm, 25mm, and 10mm from top to bottom.

[0028] In this embodiment, the screening plate 2 is used to classify and screen the coke. When classifying the coke, it is usually divided into grades with block sizes greater than 40 mm, 25-40 mm, 10-25 mm and less than 10 mm.

[0029] Reference Figure 1-2 : The transmission assembly 52 includes a connecting rod 521, a connecting block 522, a rotating block 523 and a servo motor 524. The connecting block 522 is fixedly connected to the upper inner wall of the cylinder 5, the connecting rod 521 is fixedly connected between the cylinder 5 and the rotating block 523, the rotating block 523 is rotatably connected to the upper end of the rotating shaft 4, the output shaft of the servo motor 524 is transmission-connected to the rotating block 523, and a connecting piece 525 is provided between the servo motor 524 and the support ring 6.

[0030] In this embodiment, the transmission assembly 52 is used to drive the cylinder 5 to rotate. When the second discharge port 51 rotates to the same position as the first discharge port 3, the coke is discharged from the second discharge port 3, and the servo motor 523 drives the rotating block 523 to rotate. When the second discharge port 51 of the cylinder 5 is rotated to the same position as the first discharge port 3, the servo motor 3 stops rotating. The servo motor 3 rotates under program control.

[0031] Reference Figure 2-3 The rotating member 42 is composed of four rotating plates 421, and the four rotating plates 421 are arranged in a circular array on the surface of the rotating shaft 4.

[0032] It should be noted that the outer end of the rotating plate 421 is in sliding contact with the grading barrel 1. The rotating plate 421 can prevent the coke from piling up in one place and drive the coke to move. During the movement, the coke smaller than the aperture of the screening plate 2 falls under the screening plate 2.

[0033] The lower surfaces of the three upper groups of rotating plates 421 are slidably connected to the corresponding screening plates 2 , and the lower surface of the lowest group of rotating plates 421 is slidably connected to the bottom wall of the grading barrel 1 .

[0034] In this embodiment, the rotating plate 421 is used to drive the coke falling on the screening plate 2 to rotate, so that the coke can be screened during the movement.

[0035] Reference Figure 1-2 : The support member 61 includes two long support rods 611, two short support rods 612, two first support blocks 613 and two second support blocks 614. The two first support blocks 613 are fixedly connected to the two sides of the support ring 6, the long support rod 611 is fixedly connected to the first support blocks 613, the two second support blocks 614 are fixedly connected to the two sides below the grading barrel 1, and the short support rod 612 is fixedly connected to the second support blocks 614.

[0036] In this embodiment, the support member 61 is used to support the grading barrel 1 , the cylinder 5 and the components inside the barrel, and the arrangement of the long support rod 611 and the short support rod 611 is used to maintain the inclined arrangement of the grading barrel 1 .

[0037] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
