[0038] According to a first aspect of the present application, a material and line sending device is provided, which comprises a sending module.
[0039] Hereinafter, the specific structure of the above-mentioned components of the material and line sending device according to the present embodiment will be described.
[0040] In the present embodiment, as shown in Figure 1 The sending module is provided in N groups, N being a positive integer greater than or equal to 1, such as 2, 3, 4, and the like, so that the sintered material can be distributed to different demand bins 12 via the N groups of sending modules for synchronous crushing, ensuring that the total crushing capacity matches the sintering capacity, achieving full production of sintering and saving energy consumption, improving the production efficiency of the material, reducing the labor burden without manual intervention, and reducing costs.
[0041] Specifically, in the present embodiment, as shown in Figure 1As shown, each group of sending modules includes a sending warehouse 11, a demand warehouse 12 and a sending pipeline 13. The sending warehouse 11 is used to store materials, and the demand warehouse 12 is used to receive materials. The sending pipeline 13 is respectively adapted to be connected with the sending warehouse 11 and the demand warehouse 12. The sending warehouse 11 and the demand warehouse 12 can be respectively connected to the two side ports of the sending pipeline 13 in the extension direction. Among them, the sending pipeline 13 in the first group of sending modules is provided with N-1 distribution pipelines 131, and the N-1 distribution pipelines 131 are respectively adapted to be connected with the demand warehouse 12 in the second to N groups of sending modules. Switching valves 14 are respectively provided on the N-1 distribution pipelines 131. In this way, the distribution mode or direct sending mode can be selected for the material by selecting the opening and closing of the switching valve 14, thereby providing two sending methods for the material, which is convenient for deployment and meets different production needs. It should be noted that, when the number N is 2, there is one distribution pipeline 131 on the first group of sending modules and it is connected to the demand bin 12 in the second group of sending modules; for example, when the number N is 3, there are two distribution pipelines 131 on the first group of sending modules and these two distribution pipelines 131 are respectively connected to the demand bins 12 in the second and third groups of sending modules.
[0042] More specifically, when the switching valves 14 on the N-1 distribution pipelines 131 are closed, it is the material direct delivery mode. In the material direct delivery mode, the material is only sent to the corresponding demand bin 12 through the sending pipeline 13 in each sending module, that is, the sending bin 11 in the Nth group of sending modules sends materials to the demand bin 12 in the Nth group of sending modules via the sending pipeline 13 connected thereto; when the preset material level requirements of the 2nd to Nth demand bins 12 are met in sequence, and the material is sent in parallel by adapting the opening and closing switching valves 14, the material distribution mode is selected. The distribution mode is that the 1st group of sending modules sends materials to at least one demand bin 12 in the 2nd to Nth groups of sending modules. It should be noted that the preset material level requirement of the demand bin 12 is to make the material in the demand bin 12 reach the capacity or height that meets the processing requirements of the processing equipment (such as the crushing device described below).
[0043] The switching valve 14 is used to control the connectivity or closure of the distribution pipeline 131. When materials need to be sent through the distribution pipeline 131 in the 2nd to Nth groups of sending modules, the corresponding switching valve 14 is opened so that the materials in the sending bin 11 in the 1st group of sending modules can be transported to the corresponding demand bin 12 in the 2nd to Nth groups of sending modules through the distribution pipeline 131.
[0044] The following is based on Figure 1 The structure shown in the figure illustrates the working principle of the material parallel transmission device. The figure shows four groups of transmission modules, that is, N=4. Figure 1From the perspective of , they are marked as 1# sending module, 2# sending module, 3# sending module and 4# sending module from left to right, among which 2# sending module is the 1st group of sending modules as described above; 1# sending module, 3# sending module and 4# sending module form the 2nd to 4th groups of sending modules as described above, and 3 distribution pipelines 131 are provided on the sending pipeline 13 of 2# sending module and are respectively connected to the demand bins 12 in 1# sending module, 3# sending module and 4# sending module, by controlling the opening or closing of the three switching valves 14, so that 2# sending module can selectively send materials to the four demand bins 12, and the sending order of 2# sending module can be the demand bin 12 of 2# sending module, the demand bin 12 of 1# sending module, the demand bin 12 of 3# sending module and the demand bin 12 of 4# sending module.
[0045] In a preferred embodiment, Figure 2 As shown, the material parallel sending device also includes a switch 15 arranged on the material receiving port 121 of the demand bin 12. The switch 15 can be a ball valve, wherein the switch 15 arranged on the 2nd to Nth group sending modules is used to adjust the connection between the material receiving port 121 and the sending pipeline 13 or the distribution pipeline 131, so that the materials transported in the 2nd to Nth group demand bins 12 enter the material receiving port 121 through the sending pipeline 13 or the distribution pipeline 131, thereby avoiding the occurrence of air flow reversal.
[0046] In this embodiment, if Figure 1 As shown, the material parallel sending device also includes a crushing device, which can be an air flow mill. The air flow mill is a device that uses the high-speed movement of air flow to generate strong impact collision and friction shear between material particles and between particles and the wall of the device to achieve material crushing. The demand bin 12 is set in the crushing device, and the crushing device and the sending module are set in a one-to-one correspondence. In this way, the sending pipeline 13 can transport the material to the demand bin 12 for temporary storage to prepare for subsequent crushing work.
[0047] In this embodiment, a sintering device is used to roast materials, and a crushing device is provided downstream of the sintering device, so that the crushing device can receive and crush the materials roasted by the sintering device. The sintering device can be a kiln. The sintering device is a device known in the prior art, and its working principle and structure are not further described here. In this embodiment, there is one sintering device provided, and the roasted materials are single crystal high-nickel products. The sending chamber 11 of each sending module is connected to the sintering device, so that the materials produced by the sintering device can enter the sending chamber 11.
[0048] In this embodiment, if Figure 2 As shown, each crushing device and the sending module connected thereto are arranged up and down, thus reducing the floor space occupied by the multiple crushing devices.
[0049] In the embodiment, the sending module further comprises a sending member arranged on the sending pipeline 13, which is used to provide power for the material to flow from the sending bin 11 to the demand bin 12 through the sending pipeline 13.
[0050] In the preferred embodiment, as shown in the figure, the sending bin 11 is arranged below the demand bin 12, and the sending member is a positive pressure sending device, such as a fan or other positive pressure equipment, that is, the delivery in the sending pipeline 13 is realized by using positive pressure, so as to meet the space layout and improve the feeding efficiency. Figure 2
[0051] In the preferred embodiment, the number of sending modules is not less than three, that is, preferably N≥3, and the number of crushing devices is also set to three and is connected one by one with the three sending modules, so as to ensure the reliability of the total capacity of the crushing devices matching the full production of the sintering device. It should be noted that the number of crushing devices is not limited to this, and should be set according to the actual capacity of the sintering device and the crushing device, and preferably to ensure that the total capacity of the multiple crushing devices per day is close to the capacity of the sintering device per day and reduces the cost.
[0052] In the embodiment, as shown in the figure, Figure 1 and Figure 2 The sending pipeline 13 is a stainless steel member, so it has good corrosion resistance, meets the application requirements of the production environment, and prolongs the service life of the sending pipeline 13.
[0053] Further, in the preferred embodiment, the inner wall of the sending pipeline 13 is provided with a ceramic layer, which can be formed by spraying and other processes, so as to further improve the corrosion resistance of the sending pipeline 13, and effectively resist the wear of the inner wall by the material, prolong the service life of the sending pipeline 13, and the smooth ceramic surface helps to reduce the fluid resistance, thereby improving the conveying efficiency of the material. In addition, the ceramic has high high-temperature resistance and is suitable for conveying in high-temperature environment.
[0054] According to the material parallel line sending device, the material of sintering production can be distributed to different demand bins through the N group of sending modules to be crushed synchronously, the multiple crushing production capacity and the sintering production capacity are matched, the sintering full production and energy consumption saving are realized, the production efficiency of the material is improved, the artificial intervention is not needed, the artificial burden is reduced, and the cost is reduced.
