Description

Technical Field

[0001] This invention relates to the technical field of solid-state battery manufacturing, specifically to an apparatus for preparing dual-conductive coated active materials for all-solid-state batteries. Background Technology

[0002] Solid-state batteries are a new type of battery that uses a solid electrolyte to replace the electrolyte in traditional lithium-ion batteries. The manufacturing process of solid-state batteries requires various treatments of the raw materials. The post-coating treatments, such as drying and sintering, may require a continuous production line. Therefore, the equipment may be divided into several modules: a mixing module, a first coating layer formation, a second coating layer formation, a drying module, a sintering module, and finally a collection system. When the raw materials are sintered, a large amount of flue gas is easily generated. This flue gas contains harmful substances. Since the inlet and outlet of the sintering equipment are mostly open, a large amount of flue gas will be dispersed, which will cause the surrounding air to be polluted. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a device for preparing dual-conductive coated active materials for all-solid-state batteries. This device has advantages such as being able to use a blower to discharge waste gas into a designated location for treatment, thus avoiding the spread of waste gas and environmental pollution. It also solves the problem that a large amount of flue gas is easily generated during the sintering process of raw materials. This flue gas contains harmful substances, and since the inlet and outlet of the sintering device are mostly open during sintering, a large amount of flue gas will be scattered, resulting in the pollution of the surrounding air.

[0004] To achieve the aforementioned goal of using a blower to discharge waste gas into a designated location for treatment, thus preventing the waste gas from scattering and polluting the environment, this invention provides the following technical solution: A device for preparing dual-conductive coated active materials for all-solid-state batteries, comprising a conveying device, a sintering device above the conveying device, two gas pipes fixedly connected to the sintering device, square boxes fixedly connected to each of the two gas pipes, round pipes fixedly connected to each of the two square boxes, baffles on both sides of each of the two round pipes, connecting boxes fixedly connected to each of the two round pipes, a blower fixedly installed on the connecting boxes, two vertical bars fixedly installed on both the front and rear sides of the sintering device, each of the four vertical bars having a sliding groove, lifting plates attached to both the front and rear sides of the sintering device, the two lifting plates being movably connected to the four sliding grooves respectively, square grooves being opened on the lower side of each of the two lifting plates, inclined plates fixedly installed in each of the two square grooves, fixing strips fixedly installed on both the front and rear sides of the sintering device, fixing blocks fixedly installed on each of the two fixing strips, threaded screws threaded through the two fixing blocks, the lower ends of the two screws being movably connected to the two lifting plates respectively through bearings.

[0005] Preferably, a long box is fixedly installed on the side of each of the two lifting plates that is far apart from each other, a short pipe is fixedly connected to the upper wall of each of the two long boxes, and a number of nozzles are fixedly connected to the lower wall of each of the two long boxes.

[0006] Preferably, each of the nozzles is inclined toward the sintering device, and a rotating disk is fixedly sleeved on each of the two screws.

[0007] Preferably, the two rightmost baffles of the four baffles are fixedly connected to two round tubes respectively. The left side of the two rightmost baffles of the four baffles is movably connected to a connecting column via a bearing. A rotating tube is movably sleeved on each of the two connecting columns. Several movable plates are installed on each of the two rotating tubes, and each movable plate is provided with a vent hole.

[0008] Preferably, each of the movable plates has a groove, an adsorption plate is movably connected in each groove, a number of screws are threaded onto each movable plate, and a filter plate is fixedly installed on each movable plate by the screws.

[0009] Preferably, each of the two connecting columns is provided with a transverse groove, each transverse groove is provided with a slide bar, each slide bar is connected to two rotating tubes, each rotating tube is fixedly installed with a limit block, each of the two connecting columns is provided with a limit groove, and each limit block is movably connected to each limit groove.

[0010] Preferably, each of the connecting columns has a threaded groove on its left side, and each threaded groove has a bolt threadedly connected to it. Each bolt is movably connected to the two leftmost of the four baffles via bearings. The two leftmost baffles are respectively movably and fixedly sleeved on the outer ring of the bearings on the two bolts, and the inner rings of the bearings on the two bolts are respectively fixedly sleeved on the two bolts.

[0011] Compared with the prior art, the present invention provides a device for preparing dual conductive coated active materials for all-solid-state batteries, which has the following beneficial effects:

[0012] 1. This all-solid-state battery dual-conductive coated active material preparation device can transport raw materials to a sintering device via a conveying device. The sintering device then performs sintering treatment on the raw materials, and the gas generated during sintering remains inside the sintering device. Simultaneously, a blower is started to draw gas from the sintering device, thereby removing the waste gas. At the same time, the position of the lifting plate is adjusted by rotating the screw back and forth, which in turn adjusts the position of the two inclined plates. Since the flue gas flows upward, the inclined plates can block the flue gas from flowing out of the inlet and outlet of the sintering device. Thus, the blower can use the waste gas to discharge the waste gas to a designated location for treatment, preventing the waste gas from spreading and polluting the environment.

[0013] 2. The device for preparing dual conductive coated active materials for all-solid-state batteries allows users to easily rotate the screw via a rotating disk. By connecting two short pipes to the water mechanism and the air supply mechanism respectively, water will be sprayed from the nozzle at the outlet of the sintering device to cool the raw materials after sintering. At the same time, air will be supplied to the sintering device from the inlet, which can further prevent the exhaust gas in the sintering device from escaping through the inlet and outlet.

[0014] 3. The device for preparing dual conductive coated active materials for all-solid-state batteries uses a blower to drive airflow inside the circular tube, which in turn drives each movable plate to rotate. The drawn-in waste gas then enters the circular tube and comes into full contact with the movable plates. This allows the adsorption plates to adsorb particulate matter in the waste gas before it is treated, thus pre-treating the waste gas.

[0015] 4. This all-solid-state battery dual-conductive coating active material preparation device allows the corresponding baffle to be removed after the bolts are unpacked. This allows the rotating tube to slide to the left, thereby sliding the movable plate to the left. This makes it convenient for users to disassemble and replace the adsorption plate, thus facilitating the periodic replacement and treatment of the adsorption plate. Attached Figure Description

It should be noted that the terms “front”, “rear”, “left”, “right”, “upper” and “lower”, “bottom surface” and “top surface” used in the following description refer to the directions in the drawings, and the terms “inner” and “outer” refer to the directions toward or away from the geometric center of a specific part, respectively.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-7This invention provides a technical solution: a device for preparing dual-conductive coated active materials for all-solid-state batteries, comprising a conveying device 1, a sintering device 13 disposed above the conveying device 1, two air pipes 11 fixedly connected to the sintering device 13, square boxes 37 fixedly connected to each of the two air pipes 11, round tubes 10 fixedly connected to each of the two square boxes 37, baffles 7 disposed on both sides of each of the two round tubes 10, connecting boxes 8 fixedly connected to each of the two round tubes 10, and a blower 9 fixedly installed on the connecting boxes 8, two vertical bars 15 fixedly installed on both the front and rear sides of the sintering device 13, each of the four vertical bars 15 having a sliding groove 16, lifting plates 2 attached to both the front and rear sides of the sintering device 13, the two lifting plates 2 being movably connected to the four sliding grooves 16 respectively, and the two lifting plates 2... Both sides of the sintering device 13 have square grooves 18, and inclined plates 17 are fixedly installed in both square grooves 18. Fixing strips 14 are fixedly installed on both the front and rear sides of the sintering device 13, and fixing blocks 3 are fixedly installed on both fixing strips 14. Screws 4 are threaded through both fixing blocks 3. The lower ends of the two screws 4 are movably connected to two lifting plates 2 via bearings. The raw materials can be transported into the sintering device 13 via the conveying device 1, and then the sintering device 13 will sinter the raw materials. The gas generated during sintering will remain inside the sintering device 13. Simultaneously, the blower 9 is started to draw air from the sintering device 13, thus removing the waste gas. The position of the lifting plates 2 can be adjusted by rotating the screws 4 back and forth, thereby adjusting the position of the two inclined plates 17. The position of plate 17 is adjusted so that, since the flue gas flows upward, the inclined plate 17 can block the flue gas from flowing out of the inlet and outlet of the sintering device 13. This allows the blower 9 to direct the exhaust gas to a designated location for treatment, preventing the exhaust gas from spreading and polluting the environment. Long boxes 21 are fixedly installed on the opposite sides of the two lifting plates 2. Short pipes 19 are fixedly connected to the upper walls of both long boxes 21, and several nozzles 20 are fixedly connected to the lower walls of both long boxes 21. Each nozzle 20 is inclined towards the sintering device 13. Rotary discs 12 are fixedly sleeved on both screws 4, allowing the user to easily rotate the screws 4. By connecting the two short pipes 19 to the water mechanism and the air supply mechanism respectively, water will spray from the nozzles at the outlet of the sintering device 13. After sintering, the raw materials undergo cooling treatment. Simultaneously, airflow is pumped into the sintering device 13 from its inlet, further preventing exhaust gases from escaping through the inlet and outlet. The two rightmost baffles 7 of the four baffles 7 are fixedly connected to two circular tubes 10. The left side of the two rightmost baffles 7 is movably connected to connecting columns 24 via bearings. Rotating tubes 22 are movably sleeved on both connecting columns 24. Several movable plates 23 are installed on each of the two rotating tubes 22. Each movable plate 23 has a vent hole and a groove 33. An adsorption plate 32 is movably connected to each groove 33. Several screws 31 are threaded onto each movable plate 23.Each movable plate 23 is fixedly mounted with a filter plate 30 by screws 31. The start of the blower 9 causes airflow within the circular tube 10, which in turn rotates each movable plate 23. The drawn-in exhaust gas enters the circular tube 10 and fully contacts the movable plate 23, allowing the adsorption plate 32 to adsorb particulate matter in the exhaust gas before it is treated, thus pre-treating the exhaust gas. Each of the two connecting columns 24 has a transverse groove 28, and each transverse groove 28 contains a sliding strip 29. Each sliding strip 29 connects to one of the two rotating tubes 22. Each of the two rotating tubes 22 has a limiting block 36 fixedly installed inside. Each of the two connecting columns 24 has a limiting groove 34, and each limiting block 36 connects to one of the two rotating tubes 22. Each limiting groove 34 is movably connected. Each connecting post 24 has a threaded groove 27 on its left side, and each threaded groove 27 is threaded with a bolt 5. Two bolts 5 are movably connected to the two leftmost baffles 7 of the four baffles 7 via bearings. The two leftmost baffles 7 are movably and fixedly fitted onto the outer rings of the bearings on the two bolts 5, and the inner rings of the bearings on the two bolts 5 are fixedly fitted onto the two bolts 5. By removing the bolts 5, the corresponding baffle 7 can be removed, allowing the rotating tube 22 to slide to the left, thereby sliding the movable plate 23 to the left. This facilitates the user's disassembly and replacement of the adsorption plate 32, enabling convenient periodic replacement and processing of the adsorption plate 32.

[0027] In use, the first step is to transport the raw materials to the sintering device 13 via the conveying device 1. The sintering device 13 then performs sintering on the raw materials, and the gas generated during sintering remains inside the sintering device 13. At the same time, the blower 9 is started to draw air from the sintering device 13, thereby removing the waste gas. Meanwhile, the position of the lifting plate 2 is adjusted by rotating the screw 4 back and forth, which in turn adjusts the position of the two inclined plates 17. Since the flue gas flows upward, the inclined plates 17 can block the flue gas from flowing out of the inlet and outlet of the sintering device 13. Thus, the blower 9 can be used to discharge the waste gas into a designated location for treatment, preventing the waste gas from spreading and polluting the environment.

[0028] Step 2: The rotating disk 12 allows the user to easily rotate the screw 4. By connecting the two short pipes 19 to the water mechanism and the air supply mechanism respectively, the nozzle at the outlet of the sintering device 13 will spray water to cool the sintered raw materials. At the same time, air will be pumped into the sintering device 13 from the inlet, which can further prevent the exhaust gas in the sintering device 13 from escaping through the inlet and outlet.

[0029] Step 3: Starting the blower 9 will cause the air inside the circular tube 10 to flow, which will cause each movable plate 23 to rotate. The drawn-in exhaust gas will then enter the circular tube 10 and fully contact the movable plate 23. In this way, the adsorption plate 32 can adsorb the particulate matter in the exhaust gas before treating the exhaust gas, thus pre-treating the exhaust gas.

[0030] Step 4: After removing bolt 5, the corresponding baffle 7 can be removed. Then, the rotating tube 22 can be slid to the left, and the movable plate 23 can be slid to the left. This makes it convenient for users to disassemble and replace the adsorption plate 32, and allows users to replace and process the adsorption plate 32 regularly.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
