Description

Technical Field

[0001] This invention relates to the field of lithium carbonate composition detection technology, specifically to a battery-grade lithium carbonate composition detection device and method. Background Technology

[0002] Lithium carbonate is a fundamental raw material for the production of lithium compounds and metallic lithium, and is one of the most important products in the lithium industry. It is widely used in ceramics, lithium batteries, pharmaceuticals, food, and metal smelting. With its increasing application in lithium batteries, the detection of lithium carbonate is becoming increasingly important. While spectrometers are commonly used for component analysis, they can only detect a few millimeters of the sample surface. An uneven surface on the lithium carbonate block directly affects the test results. Furthermore, insufficient contact between the lithium carbonate block and the detection probe, resulting in air gaps, also affects the accuracy of the results. When testing powdered lithium carbonate, uneven compaction can also affect component analysis. Therefore, a battery-grade lithium carbonate component detection device is needed. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a battery-grade lithium carbonate component detection device and detection method.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0005] A battery-grade lithium carbonate component detection device, comprising:

[0006] The enclosure comprises a box, a detector, and a feeding mechanism. The box is a rectangular shell. The detector is located inside the box, and the feeding mechanism is located inside the box near the detection end of the detector. The detector is a spectrometer. A fixing plate is installed on the inner wall of the box. A support seat is connected to one side of the fixing plate. A support plate 1 is fixedly installed on the surface of the fixing plate. A support plate 2 is installed on the surface of the support seat. Two connecting columns 2 are horizontally installed on the surface of the support plate 1 and are arranged in parallel. A connecting sleeve 2 is installed on the surface of the support plate 2 and is fitted onto the connecting columns 2. A spring 1 is fitted on the connecting sleeve 2 and the connecting columns 2. One end of the spring 1 is connected to the surface of the support plate 1, and the other end of the spring 1 is connected to the surface of the support plate 2. The feeding mechanism is located above the support seat.

[0007] As a further improvement to this technical solution, the feeding mechanism includes a storage shell and an extrusion mechanism. The storage shell is located above the support seat. The top of the storage shell is connected to a feed hopper through a feed pipe. The feed pipe passes through the top of the box. The storage shell is a cuboid shell with an open bottom. The support seat matches the bottom opening of the storage shell. The extrusion mechanism is located on the side wall of the storage shell. The detection end of the detector is close to the support seat.

[0008] As a further improvement to this technical solution, a pushing mechanism 1 for moving the support seat is provided inside the box. A pushing component is provided at the end of the pushing mechanism 1. The pushing component is close to the support seat. The pushing component includes a pushing plate and a pushing block. The pushing plate is located at the end of the pushing mechanism 1. The pushing block is located on one side of the pushing plate. A connecting sleeve 1 is connected to the plate surface of the pushing plate. There are two connecting sleeves 1 arranged in parallel. A connecting column 1 is connected to the side wall of the pushing block. The connecting column 1 is installed inside the connecting sleeve 1. A spring 2 is fitted on the connecting sleeve 1 and the connecting column 1. One end of the spring 2 is connected to the plate surface of the pushing plate. The other end of the spring 2 is connected to the wall of the pushing block. A guide plate is provided at the bottom of the support seat. The guide plate and the plate surface of the support seat form an obtuse angle. In the initial state, the pushing block is close to the plate surface of the guide plate.

[0009] As a further improvement to this technical solution, an installation groove is provided on the side wall of the bearing seat, and a brush body is provided in the installation groove. Multiple brush bodies are provided and evenly spaced. The end of the brush body contacts the detection end of the detector. An air extraction cylinder is horizontally provided on the side wall of the storage shell. The air extraction cylinder is a cylindrical structure with one end open and the other end closed. The closed end of the air extraction cylinder is close to the support plate.

[0010] As a further improvement to this technical solution, the brush body is a hollow rubber tube, and the wall of the brush body is equipped with brushes. A piston is matched and installed inside the suction cylinder, and a connecting rod two is connected to the piston. A support plate is fixedly installed on the top of the support plate two, and the support plate is fixedly connected to the connecting rod two. The closed end of the suction cylinder is connected to the brush body through a connecting pipe. An exhaust pipe is installed at the closed end of the suction cylinder, and a one-way valve one is installed inside the exhaust pipe. The one-way flow direction of the one-way valve one is from the suction cylinder to the exhaust pipe. A one-way valve two is installed at the connection between the connecting pipe and the suction cylinder. The one-way flow direction of the one-way valve two is from the connecting pipe to the suction cylinder.

[0011] As a further improvement to this technical solution, a vertical plate is installed on the top of the push plate, and a push plate is fixedly installed on one side of the vertical plate by a connecting rod, with the push plate close to the push block.

[0012] As a further improvement to this technical solution, a limit plate is vertically installed on the top of the push block, and an avoidance hole is opened on the surface of the limit plate, through which the push plate can pass.

[0013] As a further improvement to this technical solution, a collection box is connected to the connecting pipe, and a filter plate is installed inside the collection box.

[0014] As a further improvement to this technical solution, a receiving groove is provided on the plate surface of the storage shell, and a pressing plate is matched and arranged in the receiving groove. A second pushing mechanism is provided on the wall of the storage shell, and the pressing plate is located at the end of the second pushing mechanism.

[0015] Compared with the prior art, the progress and advantages of this invention are as follows: during the use of this invention, lithium carbonate powder is inverted and placed into the storage shell through the feed hopper and feed pipe, and then the extrusion mechanism works to extrude and shape the lithium carbonate powder in the storage shell.

[0016] As the support moves away from the fixed plate, the pusher moves to the bottom of the storage shell, causing the lumpy lithium carbonate to fall onto the pusher. As the support moves away from the fixed plate, the brush cleans the detection end of the detector, and the piston moves inside the suction cylinder to draw air, which facilitates the removal of dust from the detection end of the detector and improves the accuracy of the detection.

[0017] The lithium carbonate block is moved and brought into contact with the detection end of the detector. The detector then performs component detection on the lithium carbonate block. By extruding the lithium carbonate powder, the thickness of the compacted lithium carbonate can be made uniform. The penetration depth of the detection rays when the detector detects the lithium carbonate block is consistent, thereby improving the accuracy of lithium carbonate component detection. Placing the lithium carbonate in the chamber for detection can avoid interference from natural light on the detection spectrum. Attached Figure Description

[0033] like Figures 1-7 As shown, a battery-grade lithium carbonate component detection device includes:

[0034] The enclosure 10 comprises a rectangular box, a detector 110, and a feeding mechanism 20. The detector 110 is housed inside the enclosure 10, and the feeding mechanism 20 is located inside the enclosure 10 near the detection end of the detector 110. The detector 110 is a spectrometer. A fixing plate 140 is provided on the inner wall of the enclosure 10. A support base 230 is connected to one side of the fixing plate 140. A first support plate 141 is fixedly mounted on the surface of the fixing plate 140, and a second support plate 142 is mounted on the surface of the support base 230. A connecting column 144 is horizontally arranged on the surface of the support plate 141. There are two connecting columns 144 arranged in parallel. A connecting sleeve 143 is arranged on the surface of the support plate 142. The connecting sleeve 143 is fitted onto the connecting column 144. A spring is fitted on the connecting sleeve 143 and the connecting column 144. One end of the spring is connected to the surface of the support plate 141, and the other end of the spring is connected to the surface of the support plate 142. The feeding mechanism 20 is located above the bearing seat 230.

[0035] More specifically, the feeding mechanism 20 includes a storage shell 210 and an extrusion mechanism 220. The storage shell 210 is located above the support seat 230. The top of the storage shell 210 is connected to the feed hopper 212 through the feed pipe 211. The feed pipe 211 passes through the top of the box 10. The storage shell 210 is a cuboid shell with an open bottom. The support seat 230 matches the bottom opening of the storage shell 210. The extrusion mechanism 220 is located on the side wall of the storage shell 210. The detection end of the detector 110 is close to the support seat 230. Lithium carbonate powder is poured into the storage shell 210 through the feed hopper 212 and the feed pipe 211. Then the extrusion mechanism 220 works and extrudes the lithium carbonate powder in the storage shell 210 into a block shape.

[0036] More specifically, the housing 10 is equipped with a pushing mechanism 120 (existing technology, not described in detail) for moving the support seat 230. A pushing component 130 is located at the end of the pushing mechanism 120, close to the support seat 230. The pushing component 130 includes a pushing plate 131 and a pushing block 132. The pushing plate 131 is located at the end of the pushing mechanism 120, and the pushing block 132 is located on one side of the pushing plate 131. A connecting sleeve 133 is connected to the surface of the pushing plate 131. Two connecting sleeves 133 are provided and arranged in parallel. A connecting post 134 is connected to the side wall of the pushing block 132, and the connecting post 134 is fitted inside the connecting sleeve 133. A spring 2 is fitted onto the connecting sleeve 133 and the connecting post 134, with one end of the spring 2 touching the surface of the pushing plate 131. The other end of the spring is connected to the wall of the push block 132. The bottom of the support seat 230 is provided with a guide plate 231. The guide plate 231 and the plate surface of the support seat 230 form an obtuse angle. In the initial state, the push block 132 is close to the plate surface of the guide plate 231. The pushing mechanism 120 pushes the push plate 131 and the push block 132 to move closer to the guide plate 231. Then the push block 132 abuts against the guide plate 231, thereby driving the support seat 230 to move away from the fixed plate 140. The support seat 230 separates from the bottom of the storage shell 210. The compressed lithium carbonate in block form falls through the bottom of the storage shell 210. As the support seat 230 moves away from the fixed plate 140, the push block 132 moves to the bottom of the storage shell 210, thereby causing the block lithium carbonate to fall onto the push block 132.

[0037] like Figures 3-6 As shown, a mounting groove 232 is provided on the side wall of the support 230, and a brush body 233 is provided in the mounting groove 232. Multiple brush bodies 233 are provided and evenly spaced. The end of the brush body 233 is in contact with the detection end of the detector 110. An air extraction cylinder 240 is horizontally provided on the side wall of the storage shell 210. The air extraction cylinder 240 is a cylindrical structure with one end open and the other end closed. The closed end of the air extraction cylinder 240 is close to the support plate 141.

[0038] More specifically, the brush body 233 is a hollow rubber tube, and the wall of the brush body 233 is provided with brushes. A piston 243 is matched and installed inside the suction cylinder 240. A connecting rod 242 is connected to the piston 243. A support plate 241 is fixedly installed on the top of the support plate 142. The support plate 241 is fixedly connected to the connecting rod 242. The closed end of the suction cylinder 240 is connected to the brush body 233 through a connecting pipe 244. An exhaust pipe 246 is provided at the closed end of the suction cylinder 240, and a one-way valve is installed inside the exhaust pipe 246. First, the one-way flow direction of the one-way valve is from the air pump 240 to the exhaust pipe 246. A one-way valve is provided at the connection between the connecting pipe 244 and the air pump 240. The one-way flow direction of the one-way valve is from the connecting pipe 244 to the air pump 240. As the support seat 230 moves away from the fixed plate 140, the brush body 233 cleans the detection end of the detector 110. Moreover, the piston 243 moves inside the air pump 240 to perform air extraction, which facilitates the suction of the cleaning dust from the detection end of the detector 110.

[0039] like Figure 7 As shown, a vertical plate 137 is vertically installed on the top of the push plate 131, and a push plate 139 is fixedly installed on one side of the vertical plate 137 by a connecting rod 138. The push plate 139 is close to the push block 132.

[0040] More specifically, a limiting plate 135 is vertically installed on the top of the pusher block 132. A clearance hole 136 is opened on the surface of the limiting plate 135. The pusher plate 139 can pass through the clearance hole 136. When the block of lithium carbonate falls onto the pusher block 132, the lithium carbonate block is between the limiting plate 135 and the detection end of the detector 110. Then, the pushing mechanism 120 continues to push the pusher plate 131 to move closer to the pusher block 132. The pusher plate 139 passes through the clearance hole 136, thereby pushing the lithium carbonate block and contacting it with the detection end of the detector 110. Then, the detector 110 performs component detection on the lithium carbonate block. By extruding and molding the lithium carbonate powder, the thickness of the compacted lithium carbonate can be made uniform. The penetration depth of the detection rays when the detector 110 detects the lithium carbonate block is consistent, thereby improving the accuracy of lithium carbonate component detection.

[0041] like Figure 6 As shown, a collection box 245 is connected to the connecting pipe 244, and a filter plate is installed inside the collection box 245.

[0042] like Figure 5 As shown, a receiving groove is provided on the plate surface of the storage shell 210, and an extrusion plate 222 is matched and arranged in the receiving groove. A second pushing mechanism 221 (which is prior art and has not been described in detail) is provided on the wall of the storage shell 210. The extrusion plate 222 is located at the end of the second pushing mechanism 221. The second pushing mechanism 221 can push the extrusion plate 222 to extrude and shape the lithium carbonate powder in the storage shell 210.

[0043] Working principle:

[0044] In use, lithium carbonate powder is fed into the storage shell 210 via the feed hopper 212 and feed pipe 211. Then, the extrusion mechanism 220 extrudes the lithium carbonate powder in the storage shell 210, forming it into blocks. The pushing mechanism 120 pushes the pusher plate 131 and pusher block 132 towards the guide plate 231. The pusher block 132 then contacts the guide plate 231, causing the support seat 230 to move away from the fixed plate 140. The support seat 230 separates from the bottom of the storage shell 210, and the extruded lithium carbonate blocks fall through the bottom of the storage shell 210. As the support seat 230 moves away from the fixed plate 140, the pusher block 132 moves below the storage shell 210, causing the lithium carbonate blocks to fall onto the pusher block 132. As the support seat 230 moves away from the fixed plate 140... The brush body 233 cleans the detection end of the detector 110, and the piston 243 moves inside the vacuum cylinder 240 to perform air extraction, which facilitates the removal of cleaning dust from the detection end of the detector 110. When the block of lithium carbonate falls onto the push block 132, the lithium carbonate block is between the limiting plate 135 and the detection end of the detector 110. Then, the pushing mechanism 120 continues to push the push plate 131 towards the push block 132. The push plate 139 passes through the clearance hole 136, thereby pushing the lithium carbonate block and contacting it with the detection end of the detector 110. Then, the detector 110 performs component detection on the lithium carbonate block. By extruding and molding the lithium carbonate powder, the thickness of the compacted lithium carbonate can be made uniform. The penetration depth of the detection rays when the detector 110 detects the lithium carbonate block is consistent, thereby improving the accuracy of lithium carbonate component detection.

[0045] It should be stated that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to the present invention. However, such variations, as long as they do not depart from the spirit of the present invention, should be within the scope of protection of the present invention. Furthermore, some terminology used in this specification and claims is not limiting, but merely for ease of description.
