Description
Technical Field
[0001] The utility model belongs to the technical field of battery raw material processing, in particular to a lithium iron phosphate raw material batching sand grinding system. Background Art
[0002] Lithium iron phosphate is an important positive electrode material for lithium-ion batteries. It has the advantages of high energy density, long life, and high safety. It is widely used in energy storage equipment, power tools, light electric vehicles and other fields. The preparation methods of lithium iron phosphate mainly include solid phase method and liquid phase method. The solid phase method is to mix lithium source, iron source and phosphorus source in a certain proportion, and obtain lithium iron phosphate through high temperature calcination. The liquid phase method is to react in the solution and obtain lithium iron phosphate through precipitation, evaporation and other steps. Whether it is solid phase or liquid phase production, the obtained lithium iron phosphate needs to be sand milled to obtain raw materials with suitable mesh size. When the turbine sand mill is working, the delivery pump pumps the pre-diluted and stirred liquid-solid mixed raw materials into the cylinder, and the main shaft drives the dispersion turbine to rotate at high speed, and stirs the grinding media (glass balls, porcelain balls, zirconium oxide beads, aluminum oxide beads, etc.) in the cylinder to produce swirl and radial-axial movement, thereby forcibly grinding and dispersing the product to achieve the specified fineness and color saturation. However, it still has the following disadvantages in actual use:
[0003] When the lithium iron phosphate raw material sand mill is working, the raw material is usually sealed in it and then continuously sanded for a certain period of time so that most of the raw materials reach the appropriate mesh size. During the work, some of the raw materials will not be ground in place, affecting the uniformity of the sand milling;
[0004] When the lithium iron phosphate raw material sand mill is working, the material is directly transported to the sand mill for grinding. However, during the operation, the premixed material is easy to settle in the pipeline during the transfer and transportation, causing the pipeline transportation to be blocked and affecting the smoothness of the sand milling process. Utility Model Content
[0005] The purpose of the utility model is to provide a lithium iron phosphate raw material batching sand grinding system, which solves the problem that the lithium iron phosphate raw material sand grinding device is prone to insufficient sand grinding, and the premixed raw materials are prone to remain in the pipeline, causing pipeline transportation blockage, by arranging a grinding bin, a feed bin and an output pipe.
[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] The utility model discloses a lithium iron phosphate raw material batching sand milling system, comprising a grinding bin, a feeding bin and an output pipe, wherein a driving motor is fixed at the center of the top of the grinding bin, a mixing pipe is fixedly connected to the top of the grinding bin on one side of the driving motor, a feeding bin is fixedly connected to the top of the mixing pipe, a feeding bin is fixedly connected to the top of the feeding bin, a feeding pipe is symmetrically fixedly connected to the top of the feeding bin, a collecting bucket is fixedly connected to the bottom of the grinding bin, an output pipe is fixedly connected to the bottom of the collecting bucket, a sieve plate is fixedly provided on the upper part of the inner wall of the output pipe, a discharge pipe is fixedly provided on the lower part of the peripheral side of the collecting bucket, when working, materials are contained in the grinding bin for grinding, and various materials are transferred and transported when the feeding bin is working, and the materials ground in the grinding bin are discharged after being screened by the sieve plate through the output pipe.
[0008] Furthermore, a rotating shaft 1 is fixed to the output end of the driving motor 1, and the rotating shaft 1 passes through the top of the grinding bin. A spiral blade is fixed to the lower part of the peripheral side of the rotating shaft 1, and the spiral blade is movably connected to the lower part of the grinding bin and the focusing bucket. The driving motor drives the rotating shaft 1 to drive the spiral blade to rotate, thereby driving the grinding balls in the grinding bin to continuously roll and grind the materials.
[0009] Furthermore, a ball pipe is fixedly connected to the lower part of the peripheral side of the grinding chamber, and the ball pipe is arranged above the spiral blade. An electric control valve is fixed on the peripheral sides of the discharge pipe and the ball pipe. When the grinding chamber is working, the grinding balls are transported into it through the ball pipe, and the discharge pipe and the ball pipe are both transported on and off by the electric control valve.
[0010] Furthermore, a second driving motor is fixed at the center of the top of the feed bin, a second rotating shaft is fixed at the output end of the second driving motor, the second rotating shaft passes through the top of the feed bin and the bottom end is arranged in the upper part of the mixing tube, when the feed bin is working, the second driving motor drives the second rotating shaft to rotate, thereby driving the rotating block to rotate.
[0011] Furthermore, rotating blocks are fixed in a circular array at the lower part of the second circumferential side of the rotating shaft, and the rotating blocks are arranged in the upper part of the mixing tube. An electric control valve 2 is fixed in the middle part of the circumferential side of the mixing tube. The rotation of the second rotating shaft drives the rotating blocks to rotate, so as to fully mix the materials in the feed bin.
[0012] Furthermore, the bottom end of the rotating shaft 1 is inserted through the sieve plate, and an electric control valve 3 is fixed to the middle of the peripheral side of the output pipe, and the output pipe controls the on-off of the delivery through the electric control valve 3.
[0013] The utility model has the following beneficial effects:
[0014] The utility model solves the problem that the lithium iron phosphate raw material sand mill device is prone to insufficient sand grinding by arranging a grinding bin and an output pipe. When working, a driving motor drives a rotating shaft to rotate, driving the spiral blade to rotate. When the spiral blade rotates, the grinding balls in the grinding bin are driven to continuously rise, but the grinding balls are rolled downward under the action of gravity, so that the material in the grinding bin is continuously ground and is screened by the sieve plate on the output pipe and then transported to the output pipe. After the electric control valve is opened, the material is discharged, so that the raw material output by the sand mill in the lithium iron phosphate raw material sand mill device is more fully sanded.
[0015] The utility model solves the problem that the premixed raw materials are easily retained in the pipeline, causing the pipeline transportation to be blocked by arranging the grinding bin and the feeding bin. When working, the driving motor 2 is started, and the driving motor 2 drives the rotating shaft 2 to rotate. When the rotating shaft 2 rotates, the rotating block is driven to rotate. When the rotating block rotates, the material in the feeding bin is fully mixed. When the electric control valve 2 is opened, the material is smoothly transported to the grinding bin, so that the premixed raw materials can be transported more smoothly when working.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1
[0025] See also Figure 1-5 The utility model is a lithium iron phosphate raw material batching sand milling system, comprising a grinding bin 1, a feed bin 2 and an output pipe 3. A driving motor 101 is fixed at the center of the top of the grinding bin 1. The materials to be ground are contained in the grinding bin 1 to cooperate with the grinding operation. The driving motor 101 drives the rotating shaft 102 to rotate. The top of the grinding bin 1 on one side of the driving motor 101 is fixedly connected with a mixing pipe 205. When the mixing pipe 205 is working, the materials in the feed bin 2 are mixed and transported to the grinding bin 1. The top of the mixing pipe 205 is fixedly connected with the feed bin 2. The materials to be ground are transferred and transported through the feed bin 2. The top of the feed bin 2 is symmetrically fixedly connected with the feed pipe 2 02. When the feed pipe 202 is working, the material to be ground is transported to the feed bin 2. The bottom end of the grinding bin 1 is fixedly connected to a collecting bucket 103. The material being ground in the grinding bin 1 is collected to the bottom end through the collecting bucket 103 and transported to the output pipe 3. The bottom end of the collecting bucket 103 is fixedly connected to the output pipe 3. The upper part of the inner wall of the output pipe 3 is fixed with a sieve plate 301. When the output pipe 3 is working, unqualified raw materials are retained in the collecting bucket 103 through the sieve plate 301 to prevent the unqualified raw materials from being directly discharged. The lower part of the peripheral side of the collecting bucket 103 is fixedly connected to a discharge pipe 105. After the grinding balls in the grinding bin 1 have been used for a period of time, the grinding balls in the grinding bin 1 can be discharged through the discharge pipe 105.
[0026] Specifically, a rotating shaft 102 is fixed to the output end of a driving motor 101, and the rotating shaft 102 passes through the top of the grinding bin 1. A spiral blade 104 is fixed to the lower part of the peripheral side of the rotating shaft 102. The spiral blade 104 is movably connected to the lower part of the grinding bin 1 and the collecting bucket 103. The driving motor 101 drives the rotating shaft 102 to rotate, thereby driving the spiral blade 104 to rotate. When the spiral blade 104 rotates, the grinding balls in the grinding bin 1 are driven to continuously rise, but the grinding balls are rolled downward under the action of gravity, so that the materials in the grinding bin 1 are continuously ground.
[0027] Furthermore, the lower part of the peripheral side of the grinding chamber 1 is fixedly connected to a ball pipe 106, which is arranged above the spiral blade 104, and the peripheral sides of the discharge pipe 105 and the ball pipe 106 are fixed with an electric control valve 107. When the grinding chamber 1 is working, the grinding balls are transported into it through the ball pipe 106, and the discharge pipe 105 and the ball pipe 106 are both controlled by the electric control valve 107 to control the on and off of the transportation.
[0028] The operation process of this embodiment is as follows: when working, first open the electric control valve 107 on the ball pipe 106, and keep the electric control valve 107 on the discharge pipe 105 closed, and start the driving motor 101 at the same time to drive the spiral blade 104 to rotate, so that an appropriate amount of grinding balls can be transported to the grinding bin 1 through the ball pipe 106. After the transportation of the grinding balls is completed, close the electric control valve 107, and then the grinding balls can be transported to the grinding bin 1 through the mixing pipe 205. At this time, the driving motor 101 drives the rotating shaft 102 to rotate, driving the spiral blade 104 to rotate. When the spiral blade 104 rotates, the grinding balls in the grinding bin 1 are driven to rise continuously, but the grinding balls are rolled downward under the action of gravity, so that the materials in the grinding bin 1 are continuously ground, and after being screened by the sieve plate 301 on the output pipe 3, they are transported to the output pipe 3, and after the electric control valve 3 302 is opened, the materials are discharged.

When the feed bin 2 is working, the rotating shaft 203 is driven to rotate by the driving motor 201, and when the rotating shaft 203 rotates, the rotating block 204 is driven to rotate.
[0030] Specifically, a rotating block 204 is fixed in a circular array at the lower part of the peripheral side of the rotating shaft 203, and the rotating block 204 is arranged in the upper part of the mixing tube 205. An electric control valve 206 is fixed in the middle part of the peripheral side of the mixing tube 205. When the rotating shaft 203 rotates, the rotating block 204 is driven to rotate. When the rotating block 204 rotates, the material in the feed bin 2 is fully mixed. When the electric control valve 206 is opened, the material is transported to the grinding bin 1.
[0031] Furthermore, the bottom end of the rotating shaft 102 is inserted into the sieve plate 301 , and an electric control valve 3 302 is fixed to the middle of the peripheral side of the output pipe 3 , and the delivery on and off of the output pipe 3 is controlled by the electric control valve 2 206 .
