Its main components are fixed carbon, followed by ash, and it contains very little volatile matter and sulfur. It is silver-gray in color, has a metallic luster, is hard and porous. Depending on its use, it can be divided into three categories: metallurgical coke, foundry coke and chemical coke. According to its size, it can be divided into lump coke, crushed coke and coke chips. It is mainly used for smelting steel or other metals, and can also be used as raw materials for the manufacture of water gas, gasification and chemical industries.

[0003] In order to improve the quality of coke, it is necessary to screen out small particles of debris in the coke. Generally, the coke is screened by a screening device. When the coke is introduced into the screening device for screening, the position of the feed port is fixed, causing the introduced coke to pile up, thereby reducing the screening effect of the coke. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Reference Figure 1-3 An environmentally friendly dust suppression coke screening device includes a shell 1, the upper end of the shell 1 is connected to a feed hopper 2, the bottom end of the shell 1 is provided with a discharge port 3, a vibrating screen mechanism 4 is connected inside the shell 1, a dust collection mechanism 5 is connected to the upper end of the shell 1, a buffer material dividing member 6 for preventing coke accumulation is connected to the upper end of the inner part of the shell 1, an opening 7 is provided on the shell 1, a rotating door 8 is rotatably connected to the opening 7, and a handle is fixedly connected to the rotating door 8;

[0022] The buffer material dividing member 6 includes a connecting rod 61, one end of which is fixedly connected to the inner upper end of the shell 1, and the other end of the connecting rod 61 is fixedly connected to a circular arc plate 62, the convex surface of the circular arc plate 62 is set upward, and the circular arc plate 62 is located directly below the feed hopper 2.

[0023] Working process:

[0024] The coke to be screened is poured from the feed hopper 2 into the interior of the housing 1. The poured coke contacts the convex surface of the arc plate 62. Since the arc plate 62 is in an arc shape, the coke on the arc plate 62 is scattered and falls on the vibrating screen mechanism 4. The arc plate 62 prevents the coke from accumulating in the center of the vibrating screen mechanism 4 under the dispersion of the coke. At the same time, it plays a buffering role for the coke, reducing the collision intensity between the coke and the vibrating screen mechanism 4.

[0025] After the vibrating screen mechanism 4 is started, the coke is screened. The impurities at the screening area pass through the vibrating screen mechanism 4 and fall on the bottom end of the shell 1 and are released from the discharge port 3. At the same time, the dust collection mechanism 5 is started to absorb the dust gas raised by the shell 1 to prevent the dust gas from being released into the air.

[0026] After the screening is completed, the rotary door 8 is driven to rotate by the handle, and the rotary door 8 opens the opening 7 after rotation, and the coke on the vibrating screen mechanism 4 is taken out through the opening 7.

[0027] Example 2: Reference Figure 4As another preferred embodiment of the present invention, the difference from Example 1 is that the vibrating screen mechanism 4 includes a movable frame 41, the movable frame 41 is in contact with the inner wall of the shell 1, and springs 43 are fixedly connected on both sides of the bottom end of the movable frame 41, and one end of each spring 43 is fixedly connected to the shell 1, and a screen 42 is fixedly connected to the movable frame 41, and a vibration motor 44 is fixedly connected to the movable frame 41. After the vibration motor 44 is started, vibration is generated, and the vibration is transmitted to the movable frame 41. The movable frame 41 squeezes the spring 43, and the spring 43 contracts after being compressed, so that the movable frame 41 moves in the vertical direction, and the movable frame 41 drives the screen 42 to move, thereby screening the coke.

[0028] Example 3: Reference Figure 2 As another preferred embodiment of the present invention, the difference from Example 1 is that the dust suction mechanism 5 includes a support plate 51, which is fixedly connected to the shell 1, and a suction pump 52 is fixedly connected to the upper end of the support plate 51. The inlet end of the suction pump 52 is connected to a ring pipe 53 through a first connecting pipe, and the ring pipe 53 is connected to an air intake pipe 54. One end of the air intake pipe 54 is connected to the shell 1, and the air intake pipe 54 is provided with a plurality of air intake pipes 54 and distributed along the length direction of the ring pipe 53. The outlet end of the suction pump 52 is connected to a filter box 55 through a second connecting pipe. After the suction pump 52 is started, the plurality of air intake pipes 54 suck the dust gas in the shell 1, and the sucked dust gas is introduced into the ring pipe 53. The dust gas in the ring pipe 53 is introduced into the suction pump 52, and the dust gas in the suction pump 52 is introduced into the filter box 55 through the second connecting pipe. The filter box 55 filters the gas and releases it to prevent dust from entering the air.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
