In this process, the slurry will flow through the pipe of the iron remover, and the ferromagnetic substances adsorbed by the magnetic field will fall off the pipe as the iron remover rotates, and finally be collected.

However, the electromagnetic iron removal structure of the overall device is complex, and multiple electromagnetic rods and drive devices need to be set up, resulting in high costs for electromagnetic iron removal of slurry.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] The embodiments of the present application provide a medium conveying pipeline and a medium coating device to solve the problems in the related art that the electromagnetic iron removal structure of the device is complex, resulting in high cost of electromagnetic iron removal of slurry, and the smoothness of the slurry flow in the device is poor, which is not conducive to improving the slurry iron removal efficiency.

[0032] See also Figures 1 to 5 As shown, the first aspect of the embodiment of the present application provides a medium conveying pipeline, including:

[0033] A pipe body 1 having a channel for conveying a flowing medium, and a detachable lining member 2 is arranged on the inner wall of the pipe body 1;

[0034] The electromagnetic coil 3 is wound around the outer circumference of the tube body 1 along the length direction of the tube body 1. The electromagnetic coil 3 is used to generate a magnetic field when energized to attract magnetic substances in the flowing medium transported in the tube body 1, so as to drive the magnetic substances to adhere to the surface of the lining 2.

[0035] A detachable lining member 2 is installed on the inner wall of the pipe body 1 of the medium conveying pipeline in the embodiment of the present application, and an electromagnetic coil 3 is installed on the outer periphery of the pipe body 1 and wound along the length direction of the pipe body 1. When the electromagnetic coil 3 is energized, a magnetic field surrounding the pipe body 1 can be generated to attract magnetic substances in the flowing medium in the pipe body 1, so that the magnetic substances stay on the surface of the lining member 2 to achieve the removal of the magnetic substances.

[0036] Illustratively, when the coating slurry for battery production is transported in the tube body 1, the magnetic field generated by energizing the electromagnetic coil 3 can attract the ferromagnetic material in the slurry through the tube body 1, so that the ferromagnetic material in the slurry moves toward the tube wall of the tube body 1 and approaches the lining 2, and finally contacts and adheres to the surface of the lining 2, thereby removing the ferromagnetic material in the slurry. This has the advantages of simple structure and low slurry demagnetization cost.

[0037] In addition, the lining member 2 to which the ferromagnetic material in the attached slurry is attached can be detached from the pipe body 1, which is convenient for reuse after cleaning, thereby reducing the cost of use. The lining member 2 is arranged on the inner wall of the pipe body 1, which has little effect on the flowability of the slurry. The slurry can flow smoothly in the pipe body 1 without affecting the slurry transportation efficiency and iron removal efficiency.

[0038] Exemplarily, the lining member 2 is an inner tube matched with the inner wall of the tube body 1 and fixed in the tube body 1 by means of a snap connection or a threaded connection, or the lining member 2 is a film adhered to the inner wall of the tube body 1 and can be torn off.

[0039] In some optional embodiments, see Figure 2As shown, an embodiment of the present application provides a medium conveying pipeline, wherein the inner lining member 2 of the medium conveying pipeline is a columnar filter screen with openings at both ends, and the columnar filter screen has an inner side wall for intercepting magnetic substances.

[0040] The lining member 2 of the medium conveying pipeline in the embodiment of the present application is a columnar filter screen with openings at both ends. The outer diameter of the columnar filter screen is adapted to the inner diameter of the pipe body 1. After the columnar filter screen is installed inside the pipe body 1, the openings at both ends can allow the flowing medium conveyed by the pipe body 1 to pass through, and the inner wall of the columnar filter screen can intercept and attach magnetic substances.

[0041] For example, when the coating slurry for battery production is transported in the tube body 1, the slurry can pass through the openings at both ends of the columnar filter without affecting the flowability of the slurry. After the electromagnetic coil 3 outside the tube body 1 is energized to generate a magnetic field, the ferromagnetic material in the slurry is attracted and collides with the inner wall of the columnar filter, and is intercepted and captured by the inner wall of the columnar filter, thereby achieving effective removal of the ferromagnetic material in the slurry.

[0042] In some optional embodiments, see Figure 1 and Figure 2 As shown, an embodiment of the present application provides a medium conveying pipeline, wherein the outer side of the pipe body 1 of the medium conveying pipeline is sleeved with an outer pipe 4 coaxially arranged with the pipe body 1, and a thermal insulation interlayer 5 is filled between the inner wall of the outer pipe 4 and the outer wall of the pipe body 1.

[0043] The outer side of the pipe body 1 of the medium conveying pipeline in the embodiment of the present application is sleeved with an outer pipe 4 coaxially arranged with the pipe body 1, and the gap between the inner wall of the outer pipe 4 and the outer wall of the pipe body 1 is filled with insulation material to form an insulation interlayer 5. The insulation interlayer 5 can insulate the flowing medium transported in the pipe body 1. Specifically, when the coating slurry for battery production is transported in the pipe body 1, the insulation interlayer 5 can insulate the slurry transported in the pipe body 1 to prevent the slurry from losing temperature too quickly and causing a sudden increase in the viscosity of the slurry, thereby affecting the flow comfort of the slurry.

[0044] Exemplarily, the thermal insulation interlayer 5 is filled with polymer thermal insulation material, the outer tube 4 is made of stainless steel, and the tube body 1 is made of ceramic tube or polytetrafluoroethylene tube. The interlayer gap formed by the outer tube 4 and the tube body 1 can effectively constrain the thermal insulation interlayer 5, ensuring that the thermal insulation interlayer 5 can stably play the role of thermal insulation.

[0045] In some optional embodiments, see Figure 2 As shown, an embodiment of the present application provides a medium conveying pipeline, in which the electromagnetic coil 3 of the medium conveying pipeline is in a spiral shape and is spirally arranged in the thermal insulation interlayer 5 along the length direction of the thermal insulation interlayer 5.

[0046] The electromagnetic coil 3 of the medium conveying pipeline in the embodiment of the present application is in the shape of a spiral line. In order to ensure that the electromagnetic coil 3 can stably generate a magnetic field after being energized, in the present embodiment, the electromagnetic coil 3 is buried in the thermal insulation interlayer 5. Specifically, the electromagnetic coil 3 is spirally penetrated in the thermal insulation interlayer 5 along the length direction of the thermal insulation interlayer 5, and the two ends of the electromagnetic coil 3 respectively pass through two through holes reserved on the outer tube 4.

[0047] It should be noted that the magnetic field strength generated by the electromagnetic coil 3 when it is energized will significantly affect the efficiency of removing magnetic substances. The stronger the magnetic field strength, the faster the magnetic substances are attracted to move and adhere to the surface of the lining 2, and are more difficult to break away from the surface of the lining 2 due to the magnetic field. Exemplarily, in order to increase the strength of the magnetic field that can be generated by the electromagnetic coil 3 after it is energized, the electromagnetic coil 3 in this embodiment can use multiple wires to be wound in parallel around the outer periphery of the tube body 1 to increase the strength of the magnetic field generated by the electromagnetic coil 3 after it is energized.

[0048] In some optional embodiments, see Figure 2 As shown, an embodiment of the present application provides a medium conveying pipeline, wherein the electromagnetic coil 3 of the medium conveying pipeline is a hollow coil in the shape of a spiral wire wound by an electric heating wire.

[0049] The electromagnetic coil 3 of the medium conveying pipeline in the embodiment of the present application is a hollow coil in the shape of a spiral wire wound with an electric heating wire, which can be conveniently sleeved on the outer periphery of the pipe body 1. Since the electromagnetic coil 3 is wound with an electric heating wire, when the electromagnetic coil 3 is energized to generate a magnetic field surrounding the pipe body 1, it can convert electrical energy into thermal energy, and emit heat to insulate and heat the flowing medium transported in the pipe body 1, thereby ensuring the smooth flow of the medium.

[0050] Exemplarily, in this embodiment, the electromagnetic coil 3 wound with electric heating wire is spirally inserted into the thermal insulation interlayer 5 between the outer tube 4 and the tube body 1. When the coating slurry for battery production is transported in the tube body 1, the electromagnetic coil 3 is energized to generate a magnetic field. While the slurry in the tube body 1 is demagnetized, the heat emitted by the electromagnetic coil 3 can heat the slurry in the thermal insulation interlayer 5 and the tube body 1, thereby achieving heating and insulation of the slurry, reducing the viscosity of the slurry, and making the slurry flow more smoothly.

[0051] In some optional embodiments, see Figure 2 and Figure 4 As shown, an embodiment of the present application provides a medium conveying pipeline, in which an end portion of a lining member 2 of the medium conveying pipeline is provided with a positioning member 6 for abutting and cooperating with an end portion of a pipe body 1 .

[0052] The end of the lining member 2 of the medium conveying pipe of the embodiment of the present application is connected with a positioning member 6, and the positioning member 6 is pressed against the end of the pipe body 1 to position the lining member 2 in the pipe body 1, so as to prevent the lining member 2 from moving with the flowing medium in the pipe body 1. Exemplarily, the positioning member 6 can be a block or a clamp that cooperates with the end of the pipe body 1.

[0053] In some optional embodiments, see Figure 2 and Figure 4 As shown, an embodiment of the present application provides a medium conveying pipeline, wherein the medium conveying pipeline positioning member 6 is an L-shaped rod, the L-shaped rod having a positioning rod 61 for limiting the axial position of the lining member 2 and extending radially, and a handle 62 for limiting the radial position of the lining member 2 and extending axially.

[0054] The positioning member 6 connected to the lining member 2 in the embodiment of the present application is an L-shaped rod, which is fixed to the end of the lining member 2. The L-shaped rod includes a positioning rod 61 extending radially along the tube body 1 and a handle 62 extending axially along the tube body 1. When in use, the positioning rod 61 can abut against the ends of the tube body 1 and the outer tube 4, thereby axially positioning the lining member 2, and the handle 62 can overlap the outer wall surface of the outer tube 4, thereby radially positioning the lining member 2.

[0055] Exemplarily, in this embodiment, the lining member 2 adopts a columnar filter screen, and the ends of the columnar filter screen are fixedly connected with two symmetrically distributed L-shaped rods. The ends of the tube body 1 and the outer tube 4 are provided with grooves that engage with the positioning rod 61 on the L-shaped rod, so that the lining member 2 can be indirectly and effectively positioned by positioning the L-shaped rod.

[0056] In some optional embodiments, see Figures 1 to 5 As shown, an embodiment of the present application provides a medium conveying pipeline, wherein a sealing ring for docking and sealing a conventional pipeline 9 is provided at the end of the medium conveying pipeline body 1, and a pipe end connection is formed between the outer tube 4 and the conventional pipeline 9 through a connecting structure.

[0057] When the end of the pipe body 1 of the medium delivery pipeline of the embodiment of the present application is butted with the end of the conventional pipe 9, a sealing ring is used for extrusion sealing, and at the same time, the outer pipe 4 and the conventional pipe 9 are detachably connected through a connecting structure. Exemplarily, the connecting structure can be flanges provided on the pipe body 1 and the conventional pipe 9, and the flanges can overlap each other and be fastened with bolts. It should be noted that the conventional pipe 9 is a slurry circulation pipe used in the prior art.

[0058] In some optional embodiments, see Figures 1 to 5As shown, an embodiment of the present application provides a medium conveying pipeline, and the medium conveying pipeline connection structure includes a first mounting plate 7 fixed on an outer tube 4, and a second mounting plate 8 fixed on a conventional pipeline 9, and both the first mounting plate 7 and the second mounting plate 8 are provided with strip holes for passing bolts.

[0059] A first mounting plate 7 is fixedly connected to the outer tube 4 of the medium conveying pipeline in the embodiment of the present application via a first fixing ring, and a second mounting plate 8 is fixedly connected to the conventional pipeline 9 via a second fixing ring. Both the first mounting plate 7 and the second mounting plate 8 extend axially along the outer tube 4 or the conventional pipeline 9.

[0060] When the outer tube 4 or the conventional pipeline 9 is butt-sealed by the sealing ring, the first mounting plate 7 and the second mounting plate 8 are overlapped and fitted together, and the bolts are simultaneously passed through the strip holes on the first mounting plate 7 and the second mounting plate 8. After the outer tube 4 or the conventional pipeline 9 is butt-sealed by the sealing ring in place, the bolts are tightened to keep the outer tube 4 and the conventional pipeline 9 connected.
