Description

Technical Field

[0001] This utility model relates to the field of impurity removal technology for lithium mica raw materials, and in particular to an impurity separation device for lithium mica raw materials. Background Technology

[0002] A lepidolite raw material impurity separation device is a specialized piece of equipment used to remove impurities from lepidolite raw materials. Lepidolite is a lithium-rich mineral widely used in the production of cathode materials for lithium-ion batteries. Because lepidolite may contain various impurities, such as iron, aluminum, and silicon, effective impurity separation is necessary to improve the purity of lithium.

[0003] Existing lepidolite raw material impurity separation devices use a conveyor belt to transport the lepidolite raw material to a magnetic separator for impurity removal. However, since the impurity removal effect of the magnetic separator is limited, it may not be possible to completely remove iron-containing impurities from the lepidolite raw material using only the magnetic separator. Furthermore, the lepidolite raw material may accumulate on the conveyor belt and cannot be evenly fed into the magnetic separator, which can easily affect the impurity removal effect in the magnetic separator.

[0004] Therefore, a lithium mica raw material impurity separation device has now been developed that can pre-remove impurities from lithium mica raw materials during the conveying process, while ensuring that the lithium mica raw materials are evenly fed into the magnetic separator to ensure the subsequent impurity removal effect. Utility Model Content

[0005] To overcome the shortcomings of existing lepidolite raw material impurity separation devices, which may not be able to completely remove iron-containing impurities from lepidolite raw materials using only magnetic separators, and may cause lepidolite raw materials to accumulate on the conveyor belt and not be evenly fed into the magnetic separator, thus affecting the impurity removal effect in the magnetic separator, this utility model provides a lepidolite raw material impurity separation device that can pre-remove impurities from lepidolite raw materials during the conveying process, while ensuring that the lepidolite raw materials are evenly fed into the magnetic separator, thus ensuring the subsequent impurity removal effect.

[0006] The technical solution of this utility model is: a lithium mica raw material impurity separation device, including a first support frame, a conveyor belt, a feeding frame, a feeding plate, a first motor, a circular collar, a transmission component, a magnetic plate, a scraper, separation blocks, a collection frame, and a spreading mechanism. The first support frame is equipped with a conveyor belt on its upper part, a feeding frame is connected to the upper right side of the first support frame, a feeding plate is connected to the upper left side of the first support frame, a first motor is connected to the front left side of the first support frame, a circular collar is connected to the left side of the first support frame, a magnetic plate is rotatably connected to the circular collar, a transmission component is connected between the output shaft of the first motor and the magnetic plate, a scraper is connected to the inner left side of the first support frame, the scraper is in contact with the magnetic plate, two separation blocks are connected to the lower part of the magnetic plate, both of which are made of non-magnetic material, a collection frame is placed on the lower left side of the first support frame, the collection frame is located below the magnetic plate, and a spreading mechanism is provided on the first support frame to allow the lithium mica raw material to be spread flat on the conveyor belt.

[0007] Furthermore, the transmission assembly includes a gear ring and a gear, with the gear ring connected to the outside of the magnetic plate, and a gear connected to the output shaft of the first motor, the gear meshing with the gear ring.

[0008] Furthermore, the tiling mechanism includes a guide frame, a tiling frame, a telescopic spring, a second motor, a protrusion, and a cam. The right side of the first support frame is connected to two guide frames, and the tiling frame is slidably connected between the guide frames. Each guide frame is connected to the tiling frame by a telescopic spring. The front right side of the first support frame is connected to the second motor, and the lower side of the tiling frame is connected to a protrusion. A cam is connected to the output shaft of the second motor, and the rear side of the cam is rotatably connected to the first support frame. The protrusion and the cam are in a pressing fit.

[0009] Furthermore, multiple guide plates are provided on the upper side of the flat rack.

[0010] Furthermore, it also includes an adjustment mechanism, which includes a second support frame, a lead screw, and an adjustment frame. The second support frame is connected to both the front and rear sides of the middle of the first support frame. The lead screw is rotatably connected to each of the second support frames, and the adjustment frame is threadedly connected between the lead screws. The adjustment frame is located on the upper side of the conveyor belt.

[0011] Furthermore, gripping blocks are provided on the upper side of the lead screw.

[0012] The beneficial effects are: 1. By starting the first motor, the magnetic plate is driven to rotate through the transmission component, so that the magnetic plate adsorbs and removes some of the iron-containing impurities in the lithium mica raw material, thereby playing the role of pre-removing impurities from the lithium mica raw material during the transmission process.

[0013] 2. This utility model starts the second motor, drives the cam to rotate, and causes the cam to squeeze the protrusion. Through the force of the telescopic spring, the flat frame moves up and down in the guide frame, shaking the lithium mica raw material. This allows the lithium mica raw material to fall evenly from the flat frame onto the conveyor belt, thus ensuring that the lithium mica raw material is evenly fed into the magnetic separator and ensuring the subsequent impurity removal effect.

[0014] 3. This utility model allows for the control of the thickness of the lepidolite raw material spread on the conveyor belt by rotating the screw and adjusting the distance between the adjusting frame and the conveyor belt during the transport of the lepidolite raw material on the conveyor belt, thereby ensuring the impurity removal effect of the lepidolite raw material.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] A lithium mica raw material impurity separation device, such as Figures 1-6 As shown, the assembly includes a first support frame 1, a conveyor belt 2, a feeding frame 3, a feeding plate 4, a first motor 5, a circular collar 60, a transmission assembly 6, a magnetic plate 7, a scraper 8, a separating block 9, a collection frame 10, and a flattening mechanism 11. The conveyor belt 2 is located on the upper part of the first support frame 1. The feeding frame 3 is connected to the upper right side of the first support frame 1. The feeding plate 4 is connected to the upper left side of the first support frame 1. The first motor 5 is connected to the front left side of the first support frame 1. A circular collar 60 is connected to the left side of the first support frame 1, and a magnetic plate 7 is rotatably connected to the circular collar 60. A transmission assembly 6 is connected between the output shaft of the first motor 5 and the magnetic plate 7. The transmission assembly 6 includes a gear ring and a gear. A gear ring is connected to the outer side of the magnetic plate 7. A gear is connected to the output shaft of the first motor 5. The gear meshes with the gear ring. A scraper 8 is connected to the inner left side of the first support frame 1. The scraper 8 contacts the magnetic plate 7. Two separation blocks 9 are connected to the lower part of the magnetic plate 7. The separation blocks 9 are made of non-magnetic material. A collection frame 10 is placed on the lower left side of the first support frame 1. The collection frame 10 is located below the magnetic plate 7. A flattening mechanism 11 is provided on the first support frame 1.

[0024] like Figure 1 , Figure 4 and Figure 5As shown, the tiling mechanism 11 includes a guide frame 111, a tiling frame 112, a telescopic spring 113, a second motor 114, a protrusion 115, and a cam 116. The right side of the first support frame 1 is connected to two guide frames 111, and the tiling frame 112 is slidably connected between the guide frames 111. The upper side of the tiling frame 112 is provided with eighteen guide plates to facilitate the uniform dispersion of lithium mica raw materials. The guide frames 111 are all connected to the tiling frame 112 by telescopic springs 113. The front right side of the first support frame 1 is connected to the second motor 114. The lower side of the tiling frame 112 is connected to the protrusion 115. The output shaft of the second motor 114 is connected to the cam 116. The rear side of the cam 116 is rotatably connected to the first support frame 1. The protrusion 115 and the cam 116 are in a pressing fit.

[0025] When using this utility model, firstly, the first support frame 1 is placed in the impurity separation area of ​​the lepidolite raw material. Then, the lepidolite raw material is poured into the feeding frame 3, allowing it to fall onto the conveyor belt 2. The conveyor belt 2 is then started, causing it to transport the lepidolite raw material to the left. The raw material is then fed into the magnetic separator for impurity removal via the feeding plate 4. When the conveyor belt 2 transports the lepidolite raw material to the left to the magnetic plate 7, the first motor 5 is started. Through the meshing motion of the gear ring and gear in the transmission assembly 6, the magnetic plate 7 is rotated, causing it to adsorb and remove some of the iron-containing impurities in the lepidolite raw material. This serves to pre-remove impurities from the lepidolite raw material during the conveying process. While the magnetic plate 7 is rotating, the scraper 8 scrapes the iron-containing impurities adsorbed on the magnetic plate 7 to the separation block 9, and then they fall from between the separation blocks 9 into the collection frame 10, thus cleaning the magnetic plate 7 and preventing it from affecting the subsequent impurity removal effect. After the lithium mica raw material is poured into the feeding frame 3, it falls onto the flattening frame 112. Then, the second motor 114 is started, which drives the cam 116 to rotate. The cam 116 squeezes the protrusion 115. Through the force of the telescopic spring 113, the flattening frame 112 moves up and down in the guide frame 111 to shake the lithium mica raw material. This causes the lithium mica raw material to fall evenly from the flattening frame 112 onto the conveyor belt 2, thus ensuring that the lithium mica raw material is evenly fed into the magnetic separator and ensuring the subsequent impurity removal effect.

[0026] like Figure 1 and Figure 6 As shown, it also includes an adjustment mechanism 12, which includes a second support frame 121, a lead screw 122, and an adjustment frame 123. The second support frame 121 is connected to both the front and rear sides of the middle of the first support frame 1. The lead screw 122 is rotatably connected to each of the second support frames 121. The upper side of the lead screw 122 is provided with a gripping block for easy gripping. The adjustment frame 123 is threadedly connected between the lead screws 122 and is located on the upper side of the conveyor belt 2.

[0027] Using the adjustment mechanism 12 of this device, the thickness of the lepidolite raw material spread on the conveyor belt 2 can be controlled. When the lepidolite raw material is transported on the conveyor belt 2, the screw 122 is rotated to adjust the distance between the adjustment frame 123 and the conveyor belt 2, thereby controlling the thickness of the lepidolite raw material spread on the conveyor belt 2, so as to ensure the impurity removal effect of the lepidolite raw material.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
