Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ore dressing process, especially to a raw ore shunting system. BACKGROUND

[0002] With the continuous expansion of the scale of phosphate mining, the raw ore from the mine usually needs to be processed through multiple stages of crushing, including coarse crushing, screening and fine crushing, to meet the particle size requirements of subsequent ore dressing or sales. This traditional process not only has high energy consumption and serious equipment wear, but also causes dust pollution to increase due to the complex crushing process, which has a negative impact on the production environment and the health of the operators. Moreover, the ore receiving capacity of the physical ore dressing workshop is very limited, and it cannot completely and directly receive all the raw ore from the mine, resulting in a large amount of ore needing to be temporarily stored, which is chaotic and inefficient. There is a lack of scientific grading management during the ore storage process, making it difficult to achieve grading storage, further restricting production efficiency and resource utilization.

[0003] In addition, after the raw ore from the mine is discharged, most of the ore needs to be transported within the field with the help of vehicles, which not only increases the cost of internal transportation and loading, but also lengthens the production process, making it complex and tedious. At the same time, due to the lack of scientific storage management, it is difficult to achieve grading management during the storage process, which seriously restricts the improvement of production efficiency and affects the product quality.

The output end of the crushing device 20 is connected to the input end of the ore dressing device 302 through the transportation device 10. The input end of the ore dressing device 302 is connected to the mine bin through the transportation device 10.

[0035] In order to facilitate understanding of the inventive idea of the present application, the raw ore in the embodiments of the present application is taken as an example of phosphate ore for illustration and description.

[0036] In some embodiments, the transport device 10 can include, but not limited to, a 0# belt conveyor (hereinafter referred to as 0# belt), a 1# belt conveyor (hereinafter referred to as 1# belt), a 2# belt conveyor 102 (hereinafter referred to as 2# belt 102), a 4# belt conveyor (hereinafter referred to as 4# belt), a 5# belt conveyor (hereinafter referred to as 5# belt), a 6# belt conveyor 103 (hereinafter referred to as 6# belt 103), a 7# belt conveyor 104 (hereinafter referred to as 7# belt 104), an 8# belt conveyor, and a mobile belt conveyor 101, the 8# belt conveyor includes an 8a belt 105 conveyor 105 (hereinafter referred to as 8a belt 105) and an 8b belt 106 conveyor 106 (hereinafter referred to as 8b belt 106). The ore bin 40 can include a plurality of raw ore bins, a plurality of buffer bins, and a powder bin 404, etc., wherein the plurality of raw ore bins can include a first raw ore bin 401, a second raw ore bin 402, a third raw ore bin 403, and a fourth raw ore bin, the buffer bins can include a first buffer bin 407 and a second buffer bin 408; the screening device 301 can include a first vibrating screen and a second vibrating screen.

[0037] In particular, with reference to Figure 2 , the phosphate ore is first transported by the 0# belt in the transport device 10 to one of the ore bins (referred to as the first raw ore bin 401) for storage. When further processing is required, the output end of the first raw ore bin 401, i.e. the discharge port, is connected to the input end of the 1# belt, and the output end of the 1# belt is connected to the input end of the first vibrating screen in the screening device 301. The raw ore is screened according to particle size by the first vibrating screen, and the raw ore with small particles is transported to the 4# belt through one of the output ends of the first vibrating screen (referred to as the first output end of the first vibrating screen), and then to the 5# belt, and then to the 8a belt 105, and finally to another ore bin (referred to as the second raw ore bin 402) for storage.

[0038] The large particle phosphate ore is transported to a mobile belt conveyor 101 through another output end (referred to as a second output end of the first vibrating screen) of the first vibrating screen, and is transported to another ore bin (referred to as a first buffer bin 407) through the mobile belt conveyor 101. Specifically, the output end of the mobile belt conveyor 101 is provided with a chute, and the phosphate ore is transmitted to the first buffer bin 407 through the chute for buffering. When further processing is required, the output end of the first buffer bin 407 is connected to a 2# belt 102, and the phosphate ore is transported to another vibrating screen (referred to as a second vibrating screen) through the 2# belt 102, and is further screened according to the particle size through the second vibrating screen. Similarly, when the phosphate ore needs to be transported from the first buffer bin 407 to the 2# belt 102, a chute is connected to the first buffer bin, and the phosphate ore is transmitted to the 2# belt 102 through the chute. Part of the phosphate ore is transported to a 7# belt 104 through one of the output ends (referred to as a first output end of the second vibrating screen) of the second vibrating screen, and is transported to an ore bin (referred to as a second buffer bin 408) for storage through the 7# belt 104. When further processing is required, the second buffer bin 408 is connected to an 8a belt 105, and the phosphate ore is transported to other ore bins (for example, a third raw ore bin 403) for storage through the 8a belt 105. After the transportation and storage are completed, another part of the phosphate ore is transported to a 6# belt 103 through another output end (referred to as a second output end of the second vibrating screen) of the second vibrating screen, and is transported to the 8a belt 105 through the 6# belt 103, and is transported to other ore bins (for example, a fourth raw ore bin) for storage through the 8a belt 105.

[0039] In some embodiments, after the vibrating screen, for the ore with large particle size but high grade, crushing is not required, and the ore can be directly transported to a designated ore bin through a belt; for the ore with neither the required particle size nor the required grade, the crushing device 20 is used for crushing, and after the crushing is completed, the ore is directly sent to a powder ore bin through an 8b belt 106, thereby avoiding energy waste caused by large-scale crushing of all ores.

[0040] In some embodiments, the system can further include a birth information terminal device connected to the raw ore bin. Specifically, the birth information terminal device is connected to the first raw ore bin 401, and when the phosphate ore needs to be further processed, the phosphate ore is identified by the birth information terminal device before being transported to the 1# belt, so as to determine which grade the phosphate ore belongs to, for example, low-grade phosphate ore (i.e., the P2O5 content of the phosphate ore is less than 18%). Different grades of phosphate ore are distinguished, and the grade information of the phosphate ore is recorded in the birth information terminal device. When the phosphate ore passes through the birth information terminal device, the phosphate ore can be distributed according to the grade information, and the high-grade phosphate ore and the low-grade phosphate ore are processed differently. It should be noted that the grade of the phosphate ore needs to be determined before the phosphate ore enters the raw ore distribution system, and each grade of phosphate ore enters the same raw ore distribution system.

[0041] In some embodiments, the system can further comprise an automatic control device connected to the transportation device 10, the crushing device 20, the physical beneficiation device 30, the ore bin 40 and the birth information terminal device, which can be remotely and accurately controlled by the automatic control device.

[0042] In an alternative embodiment, an 8b belt 106 can be added, and the raw ore can be transported into the ore bin for storage through the 8a belt 105, and can be connected to the 8b belt 106 through the 8a belt 105, and transported to the ore bin for storage through the 8b belt 106. Among them, a plurality of fixed dischargers and chutes can be added to the 8b belt 106, each of the fixed dischargers is connected to a chute, and the chute is connected to the 8b belt 106 through the fixed discharger. In the embodiment of the present application, the chute includes a first chute 501, a second chute 502 and a third chute 503, and the raw ore bin connected to the 8b belt 106 through the chute includes a raw ore 1 bin, a raw ore 2 bin and a raw ore 3 bin, each of which is connected to a chute, and each of which stores raw ore of different grades. Specifically, the 8b belt 106 is connected to the raw ore 1 bin through the first chute 501, connected to the raw ore 2 bin through the second chute 502, and connected to the raw ore 3 bin through the third chute 503. When the birth information terminal device identifies the raw ore identity, the birth information terminal device will send the raw ore identity information to the 8b belt 106, and the 8b belt 106 will store the phosphate ore in different chutes according to the raw ore identity information. For example, if the raw ore identity information is low-grade phosphate ore, it will be stored in the raw ore 1 bin through the first chute 501; if the raw ore identity information is medium-grade phosphate ore, it will be stored in the raw ore 2 bin through the second chute 502; and so on. The phosphate ore is stored according to the raw ore identity information and stored in different raw ore bins. It should be noted that each chute buffer bin needs to be made of 16 manganese 16mm or more steel plates, and a buffer plate needs to be added.

[0043] In the embodiment of the present application, the phosphate ore can be divided into five grades, i.e. the raw ore identity information of the phosphate ore identified by the birth information terminal device is five, which are P6 (grade <25.51%), P6 (grade 25.51-26.50%), P7 (grade 26.51-27.50%), P8 (grade 27.51-28.50%) and P9 (grade >28.51%).

[0044] In some embodiments, when the phosphate ore needs to be further processed or sold, the birth information terminal device can generate a corresponding birth certificate, wherein the birth certificate includes a unique birth certificate code, and the birth certificate code includes a mine room number, a grade, a sampling date and a batch, so as to realize information management of the phosphate ore.

[0045] In some embodiments, in order to avoid too much raw ore quantity causing the raw ore bin to be unable to store, multiple raw ore bins and buffer bins can be added. Referring to Figure 2 and Figure 3 , a new buffer bin (referred to as a third buffer bin 409) is connected by the 8a belt 105, and the phosphate ore is temporarily stored in the third buffer bin 409 by the 8a belt 105. The third buffer bin 409 is connected to the newly added raw ore bin through the output end of the newly added belt. For example, the newly added raw ore bin can include a newly added raw ore 1 bin 405 and a newly added raw ore 2 bin 406, which are used to store phosphate ores of different grades or phosphate ores of different sales channels, etc.

[0046] In some embodiments, the conveying device 10 can also include a photoelectric sorting belt conveyor (hereinafter referred to as a photoelectric sorting belt), and the beneficiation device 302 can include a photoelectric sorting system. After the phosphate ore passes through the second vibrating screen, it enters the photoelectric sorting system through the photoelectric sorting belt, thereby realizing direct screening, accurate shunting, and standardized stacking of the phosphate ore.

[0047] In an optional implementation, referring to Figure 3 , one end of the moving belt is connected to the buffer bin, the buffer bin is connected to one end of the 2# belt 102, and the other end of the 2# belt 102 is connected to the photoelectric sorting vibrating screen 303. The photoelectric sorting vibrating screen 303 screens the phosphate ore, and the screened material can be divided into screen-over material and screen-under material, i.e., phosphate ores of different particle sizes enter the next process through different output ends. Among them, the screen-under material port of the photoelectric sorting vibrating screen 303 is connected to one end of the 6# belt 103, and the screen-under material is transported through the 6# belt 103; the screen-over material port of the photoelectric sorting vibrating screen 303 is connected to one end of the 7# belt 104, and the screen-over material is transported through the 7# belt 104.

The 2# belt 102 can also be connected to a coarse crushing feeder in the crushing device 20, and the output end of the coarse crushing feeder is connected to the 2# belt 102, so that the phosphate ore is crushed by the coarse crushing feeder. The phosphate ore is transported to the coarse crushing feeder in the crushing device 20 by the coarse crushing feeding belt 109. The chute also includes a fourth chute 504, and the tail of the coarse crushing feeding belt 109 is connected to the fourth chute 504, so that the phosphate ore is transported to the coarse crushing feeder in the crushing device 20 through the fourth chute 504. In addition, a maintenance passage can be added at the tail of the coarse crushing feeding belt 109 and sealed, for example, a 3x2 meter platform is used and the other three sides are sealed with color steel tiles to prevent dust and debris from flying. After coarse crushing, the phosphate ore enters the photoelectric sorting vibrating screen 303 through the 2# belt 102.

[0049] In some embodiments, referring to Figure 4The chute further comprises a fifth chute 505, and the rough breaking feeding belt 109 is further provided with the fifth chute 505, and an output end of the fifth chute 505 is connected to the 2# belt 102 102, so that the phosphate ore can be directly transmitted to the 2# belt 102 102 through the fifth chute 505.

[0050] In some embodiments, the second vibrating screen can be removed, directly transported to the 6# belt 103 through the 2# belt 102, and then transported to the 8a belt 105 through the 6# belt 103, and then transported to the newly added belt through the 8a belt 105, and then transported to the raw ore warehouse through the newly added belt. Alternatively, the 8b belt 106 is transported through the 8a belt 105, and then transported to multiple ore warehouses, including the raw ore 1 warehouse, the raw ore 2 warehouse, the raw ore 3 warehouse, and the fine ore warehouse.

[0051] In some embodiments, the electric roller of the conveyor of the 5# belt can be replaced by 30KW and electrically modified, and the electric roller motor of the conveyor head of the 8a belt 105 can be replaced by 55KW and electrically modified. The 7# belt 104 is reversible, and can be provided with a discharging chute for transporting the phosphate ore to the newly added buffer warehouse. Similarly, all the chute buffer warehouses need to be made of 16 manganese 16mm or more steel plates and increase the buffer plates.
