Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0036] See also Figure 1 The main idea of ​​this scheme is: when multiple electric furnaces (1#~M#) need to use materials at the same time, one or more sections of scrap steel conveying equipment 1 and material dividing and transferring devices 11 are used to evenly divide the scrap steel or convey it to the respective electric furnace inlets according to their respective demand ratios, so that the scrap steel from the same source can be directly delivered to the multiple electric furnace inlets to meet the material needs of multiple electric furnaces operating at the same time.

[0037] The scrap steel materials of multiple electric furnaces are stored in the scrap steel yard. The relative positions of the scrap steel yard and the electric furnace workshop are not fixed. The scrap steel demand of each electric furnace (each scrap steel in proportion) can be transported to the corresponding electric furnace feeding port through one or more scrap steel conveying equipment 1, scrap steel receiving device 10, connecting conveying equipment 4, vibration device, scraping device 12, dividing device 9, transfer device 11, weighing device, dust removal device 13, noise reduction facilities and other facilities, so as to realize the direct delivery of scrap steel from the same source to multiple electric furnace feeding ports, thereby meeting the material needs of multiple electric furnaces operating at the same time.

[0038] This scheme mainly includes front-end scrap steel conveying equipment 1 (section 0), scrap steel receiving device 10, vibration device, scraping device 12, material dividing device 9, transfer device 11, weighing device, receiving device 10, rear-end conveying equipment 2 (section 1 to section N), automobile receiving trough 5, scrap steel processing equipment 6, crane 7, steel grabber 8, dust removal device 13, noise reduction facilities, etc. In this embodiment, according to the scrap steel demand of the electric furnace workshop, the above devices are coordinated and operated, and the feeding rhythm of various types of scrap steel in the material yard is planned in an overall manner, so as to finally achieve the purpose of conveying scrap steel to multiple electric furnaces with high efficiency, low noise and low dust.

[0039] The qualified scrap steel is directly delivered to the feeding port of the 1# electric furnace through the 0-stage scrap steel conveying equipment 1, the receiving device 10, the dividing and transferring device 11 and other equipment, and then delivered to the feeding port of the 2#~M# electric furnaces in the same manner as above through the rear-stage conveying equipment 2 (1#~N#). The dividing device 9 located at the front end of each electric furnace (1#~M#) can automatically separate the amount of scrap steel required for each electric furnace. When the scrap steel is transported on the 0-stage scrap steel conveying equipment 1, the scrap steel on the 0-stage scrap steel conveying equipment 1 can be divided into the transferring device 11 according to the scrap steel required by each electric furnace through adjusting the angle of the dividing device 9, and then transferred to the electric furnace feeding conveyor 3 through the transferring device 11, and finally transported to the electric furnace (such as Figure 2 ).

[0040] Among them, the amount of scrap steel separated from the 1# electric furnace is The amount of scrap steel separated from the 2# electric furnace is The amount of scrap steel separated from the i# electric furnace is (Note: The structure and installation position of the material distribution device are determined by the value in []. i (i=1~M) represents the scrap steel demand per unit time of each electric furnace, and Q is the scrap steel conveying capacity per unit time of section 0 scrap steel conveying equipment).

[0041] The scraper device 12 is located in front of each material distribution device 9, and can scrape the scrap steel on the conveying equipment before entering the material distribution device 9 to a uniform distribution state, which is convenient for accurate material distribution. The vibration device and the scraper device 12 can be installed as a whole, or in other installation methods, and the two can work together to facilitate material distribution. In various areas where dust is easily generated, dust can be effectively suppressed by installing a dust removal device 13 to improve the working environment. In various areas where noise is easily generated, noise pollution can be effectively suppressed by installing noise reduction facilities.

[0042] This solution does not limit the method of transferring the scrap steel to the scrap steel conveying device 1, and the method includes:

[0043] 1) The scrap steel is hoisted to the receiving device 10 by a crane, and the receiving device 10 is transferred to the scrap steel conveying equipment 1 of section 0.

[0044] 2) The scrap steel is grabbed by the steel grabber 8 and brought to the receiving device 10, and the receiving device 10 is transferred to the scrap steel conveying equipment 1 of stage 0.

[0045] 3) The scrap steel products transported by the automobile are received through the automobile receiving trough 5 and connected to the scale plate (chain plate) conveyor, and transferred to the 0-stage scrap steel conveying equipment 1.

[0046] 4) The discharge port of the processing equipment is connected to the conveying equipment 4 to transfer the processed finished scrap steel to the 0-stage scrap steel conveying equipment 1.

[0047] The relative position of the scrap steel yard and the main plant of the electric furnace is relatively flexible. The scrap steel yard can directly transport scrap steel to the main plant of the electric furnace from all directions, and the utilization rate per unit area of ​​the site is high. After the scrap steel to be processed is processed by the scrap steel processing equipment 6, the processed finished scrap steel can be directly transferred to the 0th stage scrap steel conveying equipment through the connecting conveying equipment 4 set at the discharge port, and then transported to each electric furnace. Qualified scrap steel stored in the yard can be directly grabbed by a steel grabber 8 or a crane (with an electromagnetic suction cup) 7 to the receiving device 10, and the scrap steel is transferred to the 0th stage scrap steel conveying equipment through the receiving device, and then transported to each electric furnace (such as Figure 3 The scrap steel is transported to the receiving tank by car, and then directly unloaded into the receiving tank 5, and then transported to the 0th stage scrap steel conveying equipment through the connecting conveying equipment 4, and then transported to each electric furnace through the electric furnace feeding conveyor 3 (such as Figure 4 ).

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
