[0036] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0037] See Figures 1 to 3 As shown;

[0038] This embodiment discloses an automatic screening device for metallurgical coke, which includes:

[0039] Equipment body 1;

[0040] The rotary screen 2 is located inside the main body 1. The upper part of the main body 1 has a feed inlet 102, and the feed inlet 102 is connected to the screen 201 of the rotary screen 2 to transport the material to be processed into the rotary screen 2.

[0041] The crushing mechanism is located at one end of the main body 1 of the equipment relative to the feed inlet 102, and the crushing mechanism is connected to the screen 201 through the large particle material pipe 4.

[0042] The lower part of the main body 1 is a hopper 301, which receives the material screened by the rotary screen 2 and conveys it to the material pool 304 below the main body 1 through the first fine material outlet 302.

[0043] The crushing mechanism has a second fine material discharge port 303, through which the material processed by the crushing mechanism is conveyed to the material pool 304.

[0044] Specifically, this embodiment discloses a screening and crushing device suitable for screening and crushing prebaked anode filler metallurgical coke to obtain filler with particle size that meets process requirements. It has a high degree of automation and solves various problems of manual material handling. The device in this embodiment includes a main body 1, a rotary screen 2 located inside the main body 1, and a crushing mechanism located at one end of the main body 1. The rotary screen 2 is used to receive the material conveyed by the feed inlet 102, namely the metallurgical coke in this embodiment. According to the process requirements, a screen with a suitable aperture is selected as the screen cylinder of the rotary screen 2 (hereinafter, the screen refers to the screen cylinder of this device only). Then, under the action of the rotary screen 2, small particles and large particles can be screened. Subsequently, the large particles enter the crushing mechanism through the large particle material pipe 4 for further crushing. After crushing, they enter the material pool 304, while the material screened by the rotary screen 2 directly enters the material pool 304.

[0045] Preferably, in this embodiment, the main body 1 of the device is supported by a fixed bracket 101;

[0046] The drum shaft 202 of the rotary screen 2 is rotatably connected to both ends of the main body 1 through bearings in the bearing housing 203;

[0047] A roller shaft motor 204 for driving the roller shaft 202 to rotate is provided at one end of the main body 1 of the equipment;

[0048] The hopper 301 at the bottom of the main body 1 is configured as a cone structure with the size gradually decreasing from top to bottom, and the first fine material outlet 302 is located at the center of the hopper 301.

[0049] First, this embodiment further defines the structure of the main body 1 of the equipment, which is supported by a fixed bracket 101. Since the internal screen 201 needs to rotate, the aforementioned roller shaft 202 is rotatably connected to the main body 1 of the equipment via a bearing seat 203 and a bearing. The roller shaft 202 is driven to rotate by a roller shaft motor 204. Meanwhile, to further improve the entry of qualified material after screening into the material pool 304, the hopper 301 below the main body 1 of this embodiment is designed in a bucket shape, that is, it is formed with a structure whose size gradually decreases from top to bottom, to facilitate the flow of material. This further guides the screened metallurgical coke to the first fine material outlet 302, and finally collects it in the material pool 304.

[0050] Preferably, in this embodiment, the screen 201 of the rotary screen 2 is configured as a conical structure with an outer diameter that gradually increases from the end near the drum shaft motor 204 to the end near the crushing mechanism;

[0051] The feed inlet 102 is connected to the end of the screen 201 near the roller shaft motor 204, and the inner wall of the feed inlet 102 is formed as a feed slope, through which the material enters the rotary screen 2;

[0052] The large particle material pipeline 4 is connected to the end of the screen 201 near the crushing mechanism.

[0053] Preferably, in this embodiment, a dust collection pipe 103 is provided at the upper end of the main body 1 of the device; the dust collection pipe 103 is connected to an external dust collection device through a pipeline to guide the dust generated by screening. The dust collection device in this embodiment can be any device with a diversion function, such as an exhaust fan.

[0054] Preferably, the crushing mechanism in this embodiment includes a crusher 501 and a crusher motor 502 for driving the internal crushing rollers of the crusher 501 to rotate; the large particle material pipeline 4 is connected to the crusher feed port of the crusher 501. The crusher 501 can be a conventional equipment in the prior art. According to the size requirements of metallurgical coke particles, a crushing roller of appropriate specification is selected for crushing. The principle will not be described in detail here.

[0055] In order to guide the large particles of material that have been screened out and allow them to smoothly enter the large particle material pipeline 4, the screen 201 in this embodiment has a tapered structure forming a screen inclined surface 205 on its inner wall. The large particles of material are guided to the large particle material pipeline 4 through the screen inclined surface 205.

[0056] In this embodiment, the rotary screen 2 adjusts its rotation speed and screen aperture size according to process requirements to ensure screening accuracy and provide stable raw materials for prebaked anode production.

[0057] In actual operation, the overhead crane operator conveys the metallurgical coke into the feed inlet 102 of the equipment. The operator only needs to collect and inspect the crushed metallurgical coke. By reasonably adjusting the motor frequency and screen aperture, the particle size of the metallurgical coke is ensured to meet the production requirements. This satisfies the design requirements of automation, greatly improves work efficiency, and reduces labor costs.

[0058] The automatic screening equipment for metallurgical coke provided by this utility model, as described above, has the following beneficial effects:

[0059] The equipment of this utility model is mainly used for screening and crushing large particles of filler material in the prebaked anode production process, which can significantly reduce production costs and greatly reduce the waste of human resources. Compared with traditional manual selection, this equipment is simple and easy to operate and has a high degree of automation.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
