[0034] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] In order to solve the technical problems in the prior art of using a large amount of pure water to rinse the electromagnetic rod, resulting in large pure water loss and high treatment cost, the utility model provides a magnetic foreign matter cleaning system for an electromagnetic iron remover for a lithium iron phosphate slurry, which can minimize water consumption while ensuring the cleanliness of the conveying channel, and can significantly reduce the content of magnetic foreign matter in the discharged sewage, while saving the subsequent sewage treatment costs and eliminating the risk of environmental pollution.

[0036] See also Figure 1 , Figure 1 It is a structural schematic diagram of a magnetic foreign matter cleaning system of a lithium iron phosphate slurry electromagnetic iron remover in one embodiment of the utility model.

[0037] The utility model provides a lithium iron phosphate slurry electromagnetic iron remover magnetic foreign matter cleaning system, comprising an iron remover 1, a feed pipe 2, a discharge pipe 3, a purge assembly 4 and a slag discharge pipe 5, wherein the iron remover 1 is provided with a conveying channel 11, and the circumference of the conveying channel 11 is provided with an excitation system 12, and the excitation system 12 is used to generate magnetic force to adsorb magnetic foreign matter to the inner wall of the conveying channel 11; the feed pipe 2 is connected to one end of the conveying channel 11; the discharge pipe 3 is connected to the other end of the conveying channel 11; the purge assembly 4 is connected to one end of the conveying channel 11, and is used to blow air into the conveying channel 11; the slag discharge pipe 5 is arranged opposite to the purge assembly 4, and the slag discharge pipe 5 is connected to the other end of the conveying channel 11, and is used to discharge the iron slag in the conveying channel 11.

[0038] In this embodiment, a conveying channel 11 is provided inside the iron remover 1, and an excitation system 12 is provided on the circumference of the conveying channel 11; the feed pipe 2 and the discharge pipe 3 are respectively connected to the two ends of the conveying channel 11; the purge component 4 is connected to one end of the conveying channel 11, and the slag discharge pipe 5 is arranged opposite to the purge component 4, and the slag discharge pipe 5 is connected to the other end of the conveying channel 11. When in use, when the excitation system 12 is working, the conveying channel 11 will generate magnetism. When the slurry enters the conveying channel 11 from the feed pipe 2, under the action of the magnetic force, the iron material in the slurry will be adsorbed on the side wall of the conveying channel 11, so as to achieve the purpose of impurity removal. The slurry after impurity removal is discharged from the discharge pipe 3. The conveying channel 11 is discharged to enter the next process. When a certain amount of impurities are accumulated in the conveying channel 11, the conveying of the slurry can be stopped, the feed pipe 2 and the discharge pipe 3 are closed, the slag discharge pipe 5 is opened, and then the purge component 4 is started to blow high-pressure air into the conveying channel 11, and the excitation system 12 is closed. Under the action of the high-pressure airflow, the impurities are discharged from the slag discharge pipe 5, thereby achieving the purpose of cleaning the conveying channel 11. The purpose of cleaning the conveying channel 11 is achieved by blowing high-pressure airflow. Under the premise of ensuring the cleanliness of the conveying channel 11, the water consumption is reduced to the greatest extent, and the content of magnetic foreign matter in the discharged sewage can be greatly reduced. At the same time, the cost of later sewage treatment is saved and the risk of environmental pollution is eliminated.

[0039] In some embodiments, the conveying channel 11 is extended in a vertical direction, the purge assembly 4 is disposed at an upper end of the conveying channel 11 , and the slag discharge pipe 5 is disposed at a lower end of the conveying channel 11 .

[0040] In the present embodiment, the lithium iron phosphate slurry electromagnetic iron remover magnetic foreign matter cleaning system also includes a bracket, the iron remover 1 is installed on the upper side of the bracket, the conveying channel 11 is located in the middle of the iron remover 1 and extends in the vertical direction, the purge assembly 4 is located on the upper side of the iron remover 1, and the purge assembly 4 is connected to the upper end of the conveying channel 11, the purge assembly 4 is used to blow high-pressure air from top to bottom, and the slag discharge pipe 5 is located on the lower side of the iron remover 1 and is connected to the lower end of the conveying channel 11. With such an arrangement, when the excitation system 12 is turned off, most of the impurities can fall into the slag discharge pipe 5 under the action of their own gravity, reducing the difficulty of cleaning impurities by the purge assembly 4.

[0041] In some embodiments, the purge assembly 4 includes a fan 41 and an air inlet duct, the air inlet duct is installed at the upper end of the conveying channel 11 along the vertical direction, and the fan 41 is connected to the upper end of the air inlet duct.

[0042] In this embodiment, the air inlet duct is vertically arranged to reduce air flow loss, and a one-way valve or a valve is also provided on the air inlet duct to prevent slurry from entering the fan 41.

[0043] In some embodiments, the fan 41 is a hot air blower.

[0044] In this embodiment, the fan 41 is configured as a hot air blower, which can deliver high-pressure hot air into the conveying channel 11, dry the conveying channel 11, prevent impurities from adhering to the side walls of the conveying channel 11, and improve the cleaning effect.

[0045] In some embodiments, the discharge pipe 3 is disposed at the upper end of the conveying channel 11 , and the feed pipe 2 is disposed at the lower end of the conveying channel 11 .

[0046] In this embodiment, the feed pipe 2 and the discharge pipe 3 are located at opposite ends of the conveying channel 11, and the feed pipe 2 is arranged at the lower end of the conveying channel 11, and the discharge pipe 3 is arranged at the upper end of the conveying channel 11. The slurry flows from bottom to top. Such an arrangement can reduce the flow rate of the slurry. Since the iron remover 1 is used for treatment and the discharge pipe 3 is arranged on the same side as the fan 41, impurities can be avoided from being blown into the discharge pipe 3.

[0047] In some embodiments, the lithium iron phosphate slurry electromagnetic iron remover magnetic foreign matter cleaning system also includes a return pipe 6, which is connected to the conveying channel 11 and is arranged on the same side as the feed pipe 2, and the return pipe 6 is provided with a return valve 61.

[0048] In this embodiment, since the feed pipe 2 is arranged at the lower end of the conveying channel 11 and the discharge pipe 3 is arranged at the upper end of the conveying channel 11, when the conveying of slurry is stopped, part of the slurry will still accumulate in the conveying channel 11, which is not conducive to the cleaning of impurities. Therefore, a return pipe 6 is also provided at the lower end of the conveying channel 11. During specific use, after the feed pipe 2 and the discharge pipe 3 are closed, the return valve 61 is opened, and then the purge assembly 4 is started. Under the action of the airflow and the dead weight of the slurry, the slurry accumulated in the conveying channel 11 enters the return pipe 6, thereby emptying the conveying channel 11. Due to the action of the excitation system 12, even if air is introduced at this time, the impurities on the side wall of the conveying channel 11 will not be taken away.

[0049] In some embodiments, the lithium iron phosphate slurry electromagnetic iron remover magnetic foreign matter cleaning system further includes a flushing component 7 , which is connected to one end of the conveying channel 11 and is used to inject pure water into the conveying channel 11 .

[0050] In this embodiment, in order to further improve the cleaning effect, a flushing component 7 is also provided at the upper end of the conveying channel 11. After the purge component 4 has completed its work, the flushing component 7 is started to perform a short-term high-pressure water flushing and cleaning operation on the conveying channel 11 to thoroughly clean the impurities.

[0051] In some embodiments, the flushing component 7 includes a water supply pipe 71, a water pump 72 and a drainage pipe 73. One end of the water supply pipe 71 is connected to one end of the delivery channel 11, and the other end of the water supply pipe 71 is connected to the water outlet of the water pump 72. The water inlet of the water pump 72 is used to be connected to a pure water source, and the drainage pipe 73 is arranged at the other end of the delivery channel 11.

[0052] In this embodiment, the water supply pipe 71 is connected to the upper end of the delivery channel 11, and the drainage pipe 73 is connected to the lower end of the delivery channel 11, and pure water flushes the delivery channel 11 from top to bottom.

[0053] In some embodiments, the feed pipe 2 is provided with a feed valve 21 , the discharge pipe 3 is provided with a discharge valve 31 , the slag discharge pipe 5 is provided with a slag discharge valve 51 , the water supply pipe 71 is provided with a water supply valve 711 , and the drainage pipe 73 is provided with a sewage valve 731 .

[0054] In this embodiment, when removing impurities, the feed pipe 2 and the discharge pipe 3 need to be opened for conveying the slurry, and the water supply pipe 71 and the slag discharge pipe 5 need to be closed, and when cleaning the conveying channel 11, the feed pipe 2 and the discharge pipe 3 need to be closed, and the water supply pipe 71 and the slag discharge pipe 5 need to be opened. Therefore, valves are provided on the feed pipe 2, the discharge pipe 3, the water supply pipe 71 and the slag discharge pipe 5, and the opening and closing of each pipe are controlled by the above-mentioned valves.

[0055] In some embodiments, the lithium iron phosphate slurry electromagnetic iron remover magnetic foreign matter cleaning system further includes a cooling component 8 , wherein the cooling component 8 is connected to the iron remover 1 for cooling the iron remover 1 .

[0056] In order to better understand the present invention, the following Figure 1 The technical solution of the utility model is described in detail:

[0057] When in use, the return valve 61, the water supply valve 711, the slag discharge valve 51 and the drain valve are all in a closed state. At this time, the feed valve 21 and the discharge valve 31 are opened, and the excitation system 12 is opened to remove impurities from the slurry. After a single impurity removal is completed, the feed valve 21 and the discharge valve 31 are closed, and the return valve 61 and the fan 41 are opened to discharge the remaining slurry from the return pipe 6. Then the return valve 61 is closed, the slag discharge valve 51 is opened, and high-pressure hot air is continued to be introduced into the conveying channel 11 to dry the conveying channel 11. After drying is completed, the magnetic system is closed, impurities are discharged from the slag discharge pipe 5, the slag discharge valve 51 is closed, the drain valve is opened, the water pump 72 is started, and pure water is injected into the conveying channel 11 for flushing. After thorough cleaning is completed, the drain valve is closed.

[0058] In the present application, the device uses different valves to automatically control the direction of the internal slurry and slag. First, the feed valve 21 is opened to allow the slurry to enter the conveying channel 11 through the feed pipe 2 under the conveying action of the pneumatic diaphragm pump, and then the excitation system 12 with a maximum magnetic field strength exceeding 14000Gs inside the electromagnetic iron remover 1 is used to adsorb the magnetic foreign matter in the slurry to the inner wall of the conveying channel 11 to achieve the purpose of demagnetizing the slurry. During this period, the cooling component 8 completes the overall cooling of the iron remover 1.

[0059] In the present application, after completing a single slurry demagnetization, in order to effectively reduce the slurry loss during the demagnetization process, the system will close the feed valve 21, and then open the return valve 61 and the fan 41. The fan 41 will blow the slurry remaining on the inner wall and bottom of the conveying channel 11 to the return pipe 6 and return it to the slurry tank.

[0060] In the present application, the existing device mainly uses high-pressure water to clean the magnetic foreign matter inside the conveying channel 11 for slag discharge. In actual production, the slag frequency of the iron remover 1 is usually 1h / time, and a single slag discharge takes 40s. The slag discharge of the iron remover 1 mostly relies on pure water flushing, and the water consumption for a single slag discharge is as high as 0.2t. There are disadvantages such as large pure water loss and high treatment cost. In addition, the generated slag discharge wastewater has a certain environmental pollution risk. In view of the above situation, the present application adopts a dry, purging and collection method for wet slag to reduce the water consumption for cleaning magnetic foreign matter, that is, after the slurry recovery work is completed, the return valve 61 is automatically closed, and the fan 41 and the slag discharge valve 51 are opened successively, and the fan 41 and compressed hot air are used to dry the magnetic foreign matter adsorbed on the inner wall of the conveying channel 11. After that, the power supply of the excitation system 12 is cut off, and the fan 41 is used again to fully clean the inside of the conveying channel 11, so that the magnetic foreign matter passes through the slag discharge pipe 5 and is collected in the slag barrel;

[0061] In the present application, in order to thoroughly clean the magnetic foreign matter and avoid the risk of introducing magnetic foreign matter, the water supply valve 711 can be opened and pure water can be used to perform a short-term high-pressure water flushing and cleaning work on the inside of the conveying channel 11. The sewage generated is discharged through the sewage valve 731. The discharged sewage can be collected in the precision filtration tank for filtration, and then the main pollution indicators of the wastewater are treated under the sedimentation effect of the inclined tube sedimentation tank. The treated reclaimed water can be reused in other processes in the workshop. This link reduces water consumption to the greatest extent while ensuring the cleanliness of the conveying cylinder, and can greatly reduce the content of magnetic foreign matter and lithium iron phosphate slurry in the discharged sewage, while saving the cost of later sewage treatment and eliminating the risk of environmental pollution.

[0062] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
