[0037] The output end of the pre-treatment device is connected to the input end of the discharging device, for conveying the multiple batches of materials to be mixed to the corresponding discharging device after pre-treatment in the pre-treatment device.
[0038] Specifically, the pre-treatment device refers to the equipment for preliminary processing of the materials; the discharging device is a conveying equipment for transporting the treated materials from the pre-treatment device to the next link (batch mixing device), for ensuring the orderly flow of the materials between the devices; the multiple batches of materials refer to raw materials of different batches, types or formulas, such as iron phosphate powder of different particle size grades or additive combinations of different proportions, which need to be processed and mixed by the system as needed.
[0039] The multiple input ends of the batch mixing device are respectively connected to the output ends of the discharging devices, and the output end of the batch mixing device is connected to the input end of the post-treatment device, for conveying the batch mixed materials obtained after the batch mixing operation of all the materials in the batch mixing device to the post-treatment device.
[0040] Among them, the batch mixing device is an industrial equipment for uniformly mixing multiple materials according to the preset proportion, which usually realizes the sufficient contact and dispersion between the materials through mechanical stirring, airflow mixing or static mixer, to ensure the consistency of the final mixture. Then, the batch mixed materials obtained after the batch mixing operation are conveyed to the post-treatment device, and the post-treatment device performs a series of processing such as screening and packaging on the batch mixed materials.
[0041] Further, reference Figure 2 , Figure 2is a second system block diagram of the batch mixing system of iron phosphate provided by the embodiment of the application, wherein the specific design of the pretreatment device, the discharging device, the batch mixing device and the post-treatment device in the embodiment of the application is specifically shown, and the following will be specifically described respectively.
[0042] The pretreatment device comprises a crusher.

[0044] Specifically, the crusher is used for crushing raw material iron phosphate agglomerates or blocky materials to a target particle size, and the original materials are fed into the crusher through a conveying belt or manual feeding, and the crushed powder is pushed to a discharging temporary storage bin through pneumatic conveying or a screw conveyor.
[0045] More specifically, in the embodiment of the application, the crusher is integrated with a dust collector interface, which is directly connected with a cleaning device to adsorb the dust generated in the crushing process in real time. Referring to Figure 3 , Figure 3 is a structural schematic diagram of the batch mixing system of iron phosphate provided by the embodiment of the application. In the embodiment of the application, the crusher can be connected with a crusher trap 11 as shown in Figure 3 The trap collects the dust generated by the crusher during the crushing work process, prevents the dust from spreading into the workshop air, and according to the actual situation, the dust is recycled or used as raw material for other processes, thereby improving the utilization rate of the materials and reducing the production cost.
[0046] Further, the discharging device comprises a discharging temporary storage bin and a first negative pressure feeding machine 2.
[0047] The input end of the discharging temporary storage bin is connected with the output end of one of the crushers to receive the discharging material of the crusher.
[0048] The output end of the discharging temporary storage bin is connected with the input end of the first negative pressure feeding machine 2, and the output end of the first negative pressure feeding machine 2 is connected with one input end of the batch mixing device.
[0049] Specifically, the discharging temporary storage bin is used for temporarily storing the crushed iron phosphate powder, and buffers the capacity difference between the previous process and the subsequent process. It receives the discharging material of the crusher, and through the bottom discharge valve (such as a rotary valve), the powder is conveyed to the negative pressure feeding machine. The negative pressure feeding machine uses negative pressure airflow to convey the powder from the low-level bin (the discharging temporary storage bin) to the high-level bin (the batch mixing front temporary storage bin 3), and the powder is sucked from the discharging temporary storage bin and conveyed to the batch mixing front temporary storage bin 3 through a pipeline.

It receives the powder delivered by the negative pressure feeding machine and the auxiliary materials added manually or automatically, and then quantitatively feeds the materials to the batch mixing machine 4 through gravity or a screw conveyor. The batch mixing machine 4 is used to mix multiple batches of iron phosphate powder or additives according to a predetermined ratio, and then discharges the mixed materials through the bottom discharge port to the batch mixing post-storage bin 5.

[0057] Specifically, polyurea is a high molecular material generated by the reaction of isocyanate and amino compound. Its unique chemical structure endows the coating with multiple functions. First, the polyurea layer has strong corrosion resistance and can resist the corrosion of chemicals such as acids, bases, salts and organic solvents. In addition, the surface of the polyurea coating is smooth and hydrophobic, which can reduce the adhesion of sticky materials.

[0061] Specifically, the batch mixing temporary storage bin 5 is used for temporarily storing the mixed material, and provides a buffer for the vibrating screen 7, which can deliver the material to the vibrating screen 7 through a vibrating discharger; the vibrating screen 7 is used for screening the mixed iron phosphate material to remove clumps or oversized particles, and receives the material from the batch mixing temporary storage bin 5.
[0062] More specifically, referring to Figure 3 In the embodiment of the present application, the material processed by the batch mixer 4 is delivered to the batch mixing temporary storage bin 5, and for the purpose of uniform material distribution and delivery, the batch mixed material can be transmitted to the vibrating screen 7 through the double helix distributor 6 for processing, and the material processed by the vibrating screen 7 is delivered to the electromagnetic iron remover 9 through the second negative pressure feeder to remove ferromagnetic impurities, thereby ensuring the quality of the material output to the packaging machine 10.
[0063] More specifically, in the embodiment of the present application, the second output end of the vibrating screen 7 can also be connected to the input end of the pre-treatment device, which is used to screen the mixed batch material through the vibrating screen 7, deliver the qualified material to the packaging machine 10, and return the unqualified material to the pre-treatment device for reprocessing, thereby ensuring the utilization rate of the material.
[0064] Further, the system proposed in the embodiment of the present application also includes a cleaning device; the input end of the cleaning device is connected to the dust discharge end of the pulverizer, the first negative pressure feeder 2, the second negative pressure feeder 8, the batch mixing temporary storage bin 3, the batch mixing temporary storage bin 5 and / or the vibrating screen 7;
