Description

Technical Field

[0001] This utility model relates to the field of battery material production equipment, and in particular to a precursor remelting device. Background Technology

[0002] The ternary precursor remelting tank is used to handle waste materials generated from leaks and spills in the reactor during the production process. These materials may be found in workshop ditches or on the ground. The workshop collects and stores the waste materials in the remelting tank. Because the waste materials contain impurities such as sand and iron filings, it is necessary to remove these impurities to obtain clean precursor materials. Existing remelting tanks can only filter impurities using filter bags, which cannot effectively remove small magnetic impurities such as iron filings. Summary of the Invention

[0003] The purpose of this invention is to provide a precursor remelting device that can effectively remove magnetic impurities such as small-sized iron filings.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a precursor remelting device, which includes:

[0005] A cylindrical body having a first through hole and a second through hole, wherein the position of the first through hole on the cylindrical body is higher than the position of the second through hole on the cylindrical body;

[0006] A cylinder cover is installed on the upper end face of the cylinder body and is provided with a feed valve;

[0007] A stirring rod, which is rotatably connected to the cylinder cover and at least partially located within the cylinder body;

[0008] A drive unit is mounted on the cylinder cover and is connected in a driving manner to the stirring rod;

[0009] The dust filtration unit includes a first housing having a first air inlet and a first air outlet, and a filter bag disposed inside the first housing and located between the first air inlet and the first air outlet.

[0010] The second housing has a second air outlet connected to the first air inlet on its circumferential surface and a second air inlet at its lower end;

[0011] A magnetic rod, which is magnetic and is disposed inside the second housing;

[0012] The circulation section includes a circulation pipe connected at both ends to a first air outlet and a second through hole, a circulation pump installed on the circulation pipe, and a second air inlet located inside the cylinder.

[0013] In another embodiment, the upper end of the second housing is provided with a third through hole, and the upper end of the magnetic rod is provided with a sealing cover and a handle. The sealing cover is placed on the third through hole and the magnetic rod is suspended inside the second housing. After circulating for a certain period of time and completing the removal of magnetic materials and filtering of larger particulate matter, the magnetic rod is removed from the second housing by holding the handle, and then the adsorbed magnetic materials are removed.

[0014] In another embodiment, the lower end of the second housing has a feed section that is narrower at the top and wider at the bottom, and the second air inlet is located at the lower end of the feed section. The frustum-shaped feed inlet facilitates physical entry into the second housing.

[0015] In another embodiment, a spiral guide plate is formed on the inner wall of the feed section, which causes the material to spiral upward in the second shell, lengthening the flow path of the material and allowing the magnetic material contained therein to be fully adsorbed by the magnetic rod.

[0016] In another embodiment, the dust filtration unit includes a filter bag mounting plate disposed within the first housing, a filter bag bracket mounted on the filter bag mounting plate, a limiting rod mounted on the filter bag mounting plate, and a compression spring disposed between the limiting rod and the filter bag bracket to ensure that the filter bag bracket always tends to press against the filter bag mounting plate. The filter bag is fitted onto the filter bag bracket, dividing the first housing into a filtration side located on the same side of the filter bag as the first air inlet and a clean air side located on the same side of the filter bag as the first air outlet. When the compression spring is biased, the filter bag bracket can be removed from the filter bag mounting plate to clean the impurities filtered off the outside of the filter bag. Furthermore, when the pressure on the filtration side is too high, the filter bag bracket can be lifted by air pressure to form a gap between it and the filter bag mounting plate, thereby relieving pressure and preventing excessive pressure on the filtration side.

[0017] In another embodiment, the device further includes a heating tube disposed on the inner side wall of the cylinder, which may be a water heating tube or an electric heating tube.

[0018] In another embodiment, the upper end of the stirring rod is connected to the driving part, and a stirring bar is provided on the circumferential surface of its lower end. When the stirring bar rotates with the stirring rod, it does not interfere with the heating tube, the first housing, or the second housing.

[0019] In another embodiment, the drive unit includes a fixed bracket fixed to the cylinder cover and a drive motor mounted on the fixed bracket and connected to the stirring rod.

[0020] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: After the material is added to the cylinder through the feed valve, the stirring rod and the circulation pump are started to disperse the material. The circulation pump sucks in the powdery material through the second air inlet and sends it to the second air outlet. During this process, the magnetic substances in the material are attracted by the magnetic rod. Then, the material after demagnetization enters the first air inlet from the second air outlet, and after being filtered by the filter bag, it enters the circulation pipe through the first air outlet. It is then sent into the cylinder through the second through hole by the circulation pump for further demagnetization and filtration of larger particles. After circulating for a certain period of time, the demagnetization and filtration of larger particles can be completed quickly. Attached Figure Description

[0024] like Figure 1-3 As shown, the precursor remelting device includes: a cylinder 1, a cylinder cover 2, a stirring rod 3, a drive unit 4, a dust filter unit 5, a second shell 6, a magnetic rod 7, a circulation unit 8, and a heating tube 9.

[0025] The cylinder 1 has a first through hole 10 and a second through hole 11, with the first through hole 10 positioned higher than the second through hole 11. A cylinder cover 2 is mounted on the upper end face of the cylinder 1 and has a feed valve 12. A stirring rod 3 is rotatably connected to the cylinder cover 2, with at least a portion of it located inside the cylinder 1. A drive unit 4 is mounted on the cylinder cover 2 and is connected to the stirring rod 3 via a drive mechanism. It includes a fixed bracket 14 fixed to the cylinder cover 2 and a drive motor 15 mounted on the fixed bracket 14 and connected to the stirring rod 3. A dust filter unit 5 includes a first air inlet 16 and a second air outlet 17. The first housing 18 has an air outlet 17, and a filter bag 19 is disposed inside the first housing 18 and located between the first air inlet 16 and the first air outlet 17. One end of the first housing 18 is provided with a detachable end cap. The second housing 6 has a second air outlet 20 connected to the first air inlet 16 on its circumferential surface, and a second air inlet 21 at its lower end. A magnetic rod 7 is magnetic and disposed inside the second housing 6. The circulation part 8 includes a circulation pipe 22 connected to the first air outlet 17 and the second through hole 11 at both ends, and a circulation pump 23 installed on the circulation pipe 22. The second air inlet 21 is located inside the cylinder 1.

[0026] Specifically, the upper end of the second housing 6 is provided with a third through hole 24, and the upper end of the magnetic rod 7 is provided with a sealing cover plate 25 and a handle 26. The sealing cover plate 25 covers the third through hole 24 and suspends the magnetic rod 7 inside the second housing 6. After circulating for a certain period of time and completing the removal of magnetic materials and filtering of larger particles, the magnetic rod 7 is removed from the second housing 6 by holding the handle 26, and then the adsorbed magnetic materials are removed. The lower end of the second housing 6 has a feed section 27 that is narrower at the top and wider at the bottom. The second air inlet 21 is located at the lower end of the feed section 27, and the frustoconical feed inlet facilitates physical entry into the second housing 6. The inner sidewall of the feed section 27 is formed with spiral guide vanes 28 that rise from bottom to top, causing the material to spiral upward in the second housing 6, lengthening the flow path of the material, and allowing the magnetic materials contained therein to be fully adsorbed by the magnetic rod 7. The dust filtration unit 5 includes a filter bag mounting plate 33 disposed within the first housing 18, a filter bag bracket 29 mounted on the filter bag mounting plate 33, limiting brackets mounted on the filter bag mounting plate 33 and located on both sides of the filter bag bracket 29, a limiting rod 30 mounted above the filter bag mounting plate 33, and a compression spring 31 disposed between the limiting rod 30 and the filter bag bracket 29 to ensure that the filter bag bracket 29 always tends to press against the filter bag mounting plate 33. A filter bag 19 is fitted onto the filter bag bracket 29, dividing the first housing 18 into a filter side located on the same side as the first air inlet 16 and on the same side as the first air outlet 17. On the same side of the clean air side, the limiting rod 30 is fixed to the compression spring 31. Both ends of the limiting rod 30 can be locked under the limiting frame, so that the filter bag support 29 always tends to press on the filter bag mounting plate 33. After opening the end cover and compressing the compression spring 31 and the limiting rod 30 to offset them from the limiting frame, the filter bag support 29 can be removed from the filter bag mounting plate 33. The filter bag 19 can be removed along with the filter bag support 29, so that the impurities filtered on the outside of the filter bag 19 can be cleaned. When the pressure on the filtration side is too high, the filter bag support 29 can be lifted by air pressure and form a gap with the filter bag mounting plate 33 to release pressure and prevent the pressure on the filtration side from being too high. The heating tube 9 is located on the inner wall of the cylinder 1. It can be a water heating tube or an electric heating tube. The upper end of the stirring rod 3 is connected to the drive part 4, and the lower end of the stirring rod 3 is provided with a stirring rod 32. When the stirring rod 3 rotates with the stirring rod 3, it does not interfere with the heating tube 9, the first housing 18 and the second housing 6.

[0027] The principle of this utility model is as follows: After the material is added to the cylinder 1 through the feed valve 12, the drive motor 15 drives the stirring rod 3 to rotate, and the circulation pump 23 drives the gas and material flow in the device. The stirring rod 3 disperses the material, and the circulation pump 23 sucks in the dust-like material through the second air inlet 21 and sends it to the second air outlet 20. During this process, the magnetic substances in the material are attracted by the magnetic rod 7. Then, the material after removing the magnetic substances enters the first air inlet 16 through the second air outlet 20, and after being filtered by the filter bag 19, it enters the circulation pipe 22 through the first air outlet 17. Then, it is sent into the cylinder 1 through the second through hole 11 by the circulation pump 23 for further removal of magnetic substances and filtration of larger particles. After circulating for a certain period of time, the removal of magnetic substances and filtration of larger particles are completed, and the material is taken out from the discharge valve 13 at the bottom of the cylinder.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
