[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] In order to solve the technical problem that the changes in the composition of different batches of laterite nickel ore raw materials affect the stability of subsequent processing technology, the present application provides a laterite nickel ore blending equipment, which can control the feed ratio by controlling the flow of different belt lines, and designs an automatic control system to realize automatic and remote control of the flow.

[0020] It should be noted that the laterite-nickel ore blending equipment described in the present application is used for but not limited to the blending of laterite-nickel ore. For the convenience of explanation, in the present application, only the laterite-nickel ore blending equipment is used for the blending of laterite-nickel ore as an example for explanation. The principle of applying the laterite-nickel ore blending equipment to the blending of other ores is essentially the same as that applied to laterite-nickel ore, and will not be described in detail here.

[0021] See also Figure 1 , Figure 1 This is a structural schematic diagram of a laterite nickel ore blending equipment in an embodiment of the present application. The laterite nickel ore blending equipment includes multiple belt conveyor lines 1, a feed mixing module 2, a flow control device 3, a central control system 4 and a data input module 5. The multiple belt conveyor lines 1 are used to convey different batches of laterite nickel ore; the feed mixing module 2 is arranged at the end of the belt conveyor line 1, and is used to mix different batches of laterite nickel ore; the flow control device 3 is arranged on each of the belt conveyor lines 1, and is used to adjust the belt speed to control the flow of different batches of laterite nickel ore; the central control system 4 is used to receive the component detection data of each batch of laterite nickel ore collected by the data input module 5 and calculate the flow ratio according to the component detection data, and then control the action of the flow control device 3 according to the flow ratio; the data input module 5 is used to input the component detection data of each batch of laterite nickel ore into the central control system 4. When each batch of laterite nickel ore arrives, its component content is manually tested, and the batch and component content can be directly input into the central control system 4 through the data input module 5 in the laboratory. A flow control device 3 is correspondingly provided at the feeding end of the belt conveyor line 1. When the batch of laterite nickel ore raw material pile 7 is replaced, the central control system 4 calls the laterite nickel ore component content of the batch and the laterite nickel ore component content being transported by other several belt lines according to the data results received from the data input module 5, automatically calculates the flow of several belt lines and controls the automatic regulation of the belt conveyor to ensure that the feeding requirements are met.

[0022] In one embodiment, see Figure 1In order to control the flow rate of the ore conveying on the belt conveyor line 1, the flow control device 3 includes a flow sensor 31 and a frequency converter 32. The frequency converter 32 is electrically connected to the drive motor of the belt conveyor line 1 and is used to adjust the speed of the drive motor of the belt conveyor line 1. The flow sensor 31 is installed on the belt conveyor line 1 to detect the flow rate of laterite nickel ore. The flow sensor detects the ore flow rate and the frequency converter controls the belt conveying speed, which are common technical applications in industrial automation. These two technical means are used to monitor and adjust the material conveying amount, respectively, to ensure that the material supply in the production process is stable and controllable. Among them, the flow sensor can use a sensor that can detect the flow rate, such as a weight sensor, a photoelectric sensor or an ultrasonic sensor, wherein the weight sensor calculates the flow rate by measuring the weight of the ore on the conveyor belt; the photoelectric sensor estimates the flow rate by emitting and receiving light beams and detecting the situation of blocking light when the material passes; the ultrasonic sensor estimates the flow rate by emitting and receiving ultrasonic signals and measuring the change in the material stacking height. There is no unique limitation on the type of sensor, and one or more combinations can be used for detection to obtain a more accurate detection data. In addition, the frequency converter is a device used to adjust the speed of the motor. By changing the frequency of the motor power supply, the motor speed can be adjusted steplessly. In the mineral conveying system, the frequency converter is usually used to control the speed of the belt conveyor to meet different production needs.

[0023] In one embodiment, see Figure 2 The central control system 4 includes a data receiving unit 41, a calculation unit 42 and a control unit 43. The data receiving unit 41 is electrically connected to the data input module 5 for receiving component detection data from the laboratory; the calculation unit 42 is electrically connected to the data receiving unit 41 for calculating the flow ratio according to the component detection data; the control unit 43 is electrically connected to the calculation unit 42 and the flow control device 3 for sending a control signal to the flow control device 3 to adjust the belt speed according to the flow ratio calculated by the calculation unit 42.

[0024] For further information, see Figure 1 The laterite nickel ore blending equipment also includes a remote monitoring module 6, which is communicated with the central control system 4 and is used to monitor the operating status and flow of the belt conveyor line 1 in real time. The remote monitoring module 6 communicates data with the central control system 4 to allow the user to remotely control the equipment, such as adjusting parameters, starting or stopping the equipment, etc.

[0025] In one embodiment, see Figure 3 and Figure 4In order to mix the mineral materials uniformly when multiple belt conveyor lines 1 convey multiple batches of mineral materials, the feeding mixing module 2 includes a primary mixing platform 21, a secondary mixing platform 22 and a tertiary mixing platform 23. The primary mixing platform 21, the secondary mixing platform 22 and the tertiary mixing platform 23 are connected in sequence from top to bottom. The primary mixing platform 21 is used to divide the multiple belt conveyor lines 1 into multiple groups, and mix the materials conveyed by each group respectively. The secondary mixing platform 22 is used to receive the materials mixed by the primary mixing platform 21 and stir and mix them in one direction. The tertiary mixing platform 23 is used to receive the materials mixed by the secondary mixing platform 22 and stir and mix them in the opposite direction. Multiple batches of mineral materials are mixed in detail by grouping, first mixed in a single group, and then mixed in multiple groups. Moreover, the existing stirring is carried out by stirring in two directions to improve the uniformity of mixing, so as to avoid the situation where the materials are mixed unevenly under the feeding of multiple batches and multiple lines.

[0026] Preferably, the number of a group of belt conveyor lines 1 is two, and the multiple groups of belt conveyor lines 1 are distributed in a circle with the primary mixing platform 21 as the center, and cut into the secondary mixing platform 22 in a smooth arc tangent.

[0027] Furthermore, the primary mixing platform 21 is in the shape of a circular bucket. When the mineral material enters, it can slide toward the center along the conical wall of the circular bucket. A plurality of groups of arc-shaped guide channels 2101 are arranged on the primary mixing platform 21. The number of the arc-shaped guide channels 2101 in each group is multiple, and each corresponds to one of the belt conveyor lines 1. The arc-shaped guide channels 2101 in a group are all inclined downward and converge at the bottom. Through the arc-shaped diversion, the mineral material has a certain acceleration, and a collision occurs at the confluence, forming a certain mixing effect.

[0028] Furthermore, a first stirring mechanism 2102 is provided at the bottom junction of each group of the arc-shaped flow guide channels 2101 to improve the mixing degree of the mineral materials at the junction.

[0029] Furthermore, the secondary mixing platform 22 is arranged at the bottom of the primary mixing platform 21, and a second stirring mechanism 2201 is arranged therein. The secondary mixing platform 22 is also in a round bucket shape, and its slope is smaller than the slope of the primary mixing platform 21. By lowering the slope, the speed at which the mineral material is fed downward is slowed down, and the second stirring mechanism 2201 is cooperated for stirring to improve the degree of mixing.

[0030] Furthermore, the three-stage mixing platform 23 includes a cylindrical portion 231 and a round bucket bottom 232 connected to the bottom of the cylindrical portion 231. The cylindrical portion 231 is arranged at the bottom of the second mixing platform. A third stirring mechanism 2301 is arranged on the inner side of the cylindrical portion 231 for stirring the materials on the cylindrical portion 231 and the round bucket bottom 232. The stirring direction is opposite to the stirring direction of the second stirring mechanism 2201, forming a comprehensive stirring effect, so that the homogenization effect is better.

[0031] Furthermore, the feed mixing module 2 also includes a crushing channel 24, which is arranged at the bottom of the three-stage mixing platform 23. The crushing channel 24 is used to receive the materials mixed by the three-stage mixing platform 23 and crush large particles. In order to avoid the presence of larger particles in the mixed mineral materials, the mineral materials are crushed by the crushing mechanism built into the crushing channel 24. The crushing action also has a certain stirring effect on the mineral materials, which can improve the uniformity of the mineral materials and the uniformity of the particles.

[0032] It is understandable that if there are many large particles in the ore, the crushing channel 24 can be set up at the end of each belt conveyor line 1, and each batch of ore can be crushed separately and then mixed.

[0033] In order to better understand this application, the following Figures 1 to 4 The technical solution of this application is described in detail: The staff first analyzes the composition of each batch of laterite nickel ore arriving in the laboratory, including parameters such as metal content, particle size distribution, and moisture, and then imports it into the central control system 4 through the data input module 5; at the same time, multiple belt conveyor lines 1 start working, each line is responsible for conveying different batches of laterite nickel ore, and a flow sensor 31 is installed on the belt conveyor line 1 to monitor the conveying volume in real time. The central control system 4 controls the frequency converter 32 to adjust the belt speed according to the composition data of each batch, so as to control the flow ratio of different batches of raw materials, so that the composition of each element in the multiple batches of ore is relatively stable in the ore blending, avoiding the impact on the subsequent process; finally, the multiple batches of ore are mixed in multiple stages through the first-level mixing platform 21, the second-level mixing platform 22 and the third-level mixing platform 23, and the crushing channel 24 is provided to crush large particles to improve the particle uniformity and mixing uniformity of the ore.

[0034] The specific implementation methods of the present application described above do not constitute a limitation on the protection scope of the present application. Any other corresponding changes and modifications made according to the technical concept of the present application should be included in the protection scope of the claims of the present application.
