Description

Technical Field

[0001] The invention belongs to the technical field of battery preparation, and in particular is a high-performance battery solid electrolyte preparation device. Background Art

[0002] The high-performance battery solid electrolyte preparation device is a device specially used to manufacture solid electrolytes in high-performance batteries. It integrates a variety of advanced process technologies and functional modules, and can accurately control the raw material ratio, reaction conditions and processing flow. It aims to transform the relevant raw materials into solid electrolytes with excellent properties such as high ionic conductivity, good chemical stability and thermal stability through a series of physical or chemical operations, laying a key foundation for the research and development and production of high-performance batteries.

[0003] The preparation process of battery solid-state electrolytes involves a variety of raw materials, which may include lithium salts, polymer matrix materials and various additives. The materials need to be stirred during preparation to ensure that these raw materials are fully mixed and produce chemical reactions, which is conducive to the formation of high-quality solid-state electrolyte structures and avoids local excessive concentrations or uneven composition.

[0004] If the stirring blade is used for a long time, its surface may be worn. Especially when processing raw materials containing solid particles or high-viscosity electrolyte precursor materials, the friction between the stirring blade and the material will be more intense, which will cause damage to the surface of the stirring blade over time and affect the stirring effect. In addition, stirring blades of different shapes or materials may be required at different stages of the preparation process, so the stirring blades need to be replaced. In some existing technologies, the stirring blades are generally fixed in the stirring module by bolts. When replacing them, they need to be removed by turning the bolts one by one, and then the replaced stirring blades need to be installed by turning the bolts. This is more troublesome, time-consuming and labor-intensive. Therefore, a high-performance battery solid electrolyte preparation device is proposed to address the above problems.

[0011] Preferably, the clamping block is slidably connected to the inner wall of the connecting block, the clamping block is clamped to the clamping groove, and the handle passes through the outer wall of the rotating rod.

[0012] Preferably, the unloading mechanism comprises a fixed shaft, the outer wall of the fixed shaft is elastically connected to a baffle via a spiral spring, the outer wall of the support plate is fixedly connected to a solvent tank, and the outer wall of the rotating rod is fixedly connected to an extrusion plate.

[0013] Preferably, the fixed shaft is fixedly connected to the outer wall of the support plate, and the extrusion plate is in contact with the outer wall of the baffle.

[0014] Preferably, one end of the spiral spring is fixedly connected to the inner wall of the baffle, and the other end of the spiral spring is fixedly connected to the outer wall of the fixed shaft.

[0015] Preferably, the baffle is rotatably connected to the outer wall of the fixed shaft, and the baffle is in contact with the outer wall of the bottom end of the solvent tank.

[0016] Preferably, a ball bearing is connected to the outer wall of the stirring blade, a control rod is hinged on the outer wall of the stirring blade, and a guide groove is provided on the inner wall of the preparation tank.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention cooperates with structures such as the moving rod and the mounting block, and by moving the handle downward, the moving rod is driven to move synchronously, so that the connecting rod can be moved downward, and the hinged rod is driven to flip, so that the two groups of clamping blocks are simultaneously moved toward the middle and out of contact with the clamping slot, so that the limit of the mounting block can be released, and the mounting block and the stirring blade can be removed at the same time for replacement or maintenance.

[0019] The present invention cooperates with structures such as a baffle plate and an extrusion plate. When the motor drives the rotating rod to rotate and stirs the material in the preparation tank, the extrusion plate on the outer wall of the rotating rod will squeeze the baffle plate to rotate it to a certain angle, and open the opening below the solvent tank, so that the solvent can fall into the preparation tank. When the rotating rod continues to rotate until the extrusion plate and the baffle plate are out of contact, the baffle plate rotates in the opposite direction under the elastic force of the scroll spring, and the opening below the solvent tank is closed, so that quantitative automatic material discharge can be completed once, so that there is no need to pour too much solvent at one time before stirring. By automatically pouring the solvent quantitatively during the stirring process, the solvent and the material can be mixed more evenly, thereby avoiding the problem that too much solvent may cause the material to be uneven, thereby affecting the quality of solid electrolyte preparation.

[0020] The present invention cooperates with structures such as guide grooves and balls. During the stirring process, the balls on the outer wall of the top group of stirring blades move along the inner wall of the guide groove and swing up and down with the guide groove. The control rod can drive the remaining multiple groups of stirring blades to swing with the same amplitude, thereby increasing the mixing effect of the solid electrolyte material and the solvent, making the material and the solvent mix more evenly, thereby improving the efficiency and quality of the preparation.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 5 As shown, the present invention provides a high-performance battery solid electrolyte preparation device, including a preparation tank 1, the outer wall of the preparation tank 1 is provided with a feeding mechanism 3, the top outer wall of the preparation tank 1 is fixedly connected with a fixing plate 4, the top outer wall of the preparation tank 1 is fixedly connected with a supporting plate 5, and the inner wall of the preparation tank 1 is provided with a stirring mechanism 2; the stirring mechanism 2 includes a motor 201, the output shaft of the motor 201 is fixedly connected with a rotating rod 202, and the inner wall of the rotating rod 202 is elastically connected with a moving rod 204 through a reset spring 213, The outer wall of the movable rod 204 is fixedly connected to the handle 203, the outer wall of the rotating rod 202 is fixedly connected to the connecting block 205, the outer wall of the connecting block 205 is clamped with the mounting block 206, the inner wall of the mounting block 206 is provided with a clamping groove 207, the outer wall of the mounting block 206 is hinged with a stirring blade 208, the outer wall of the movable rod 204 is fixedly connected to the connecting rod 209, the outer wall of the connecting rod 209 is hinged with a clamping block 211 through a hinge rod 210, and the outer wall of the clamping block 211 is fixedly connected to a connecting spring 212.

[0031] The above scheme is adopted: the preparation tank 1 is the main body of the battery solid electrolyte preparation device, the material used for preparing the solid electrolyte can be placed in the preparation tank 1, and other liquids such as solvents are added, and stirred by the stirring mechanism 2 to mix them to obtain a polymer solid electrolyte with good performance; the motor 201 serves as the power source of the stirring mechanism 2, and its output shaft is fixedly connected to the rotating rod 202. When the motor 201 is started, it drives the rotating rod 202 to rotate on the inner wall of the fixed plate 4, and the stirring blade 208 is installed on the outside of the rotating rod 202 through the mounting block 206 and the connecting block 205. When the rotating rod 202 rotates, the stirring blade 208 can stir.

[0032] like Figures 1 to 5 As shown, the motor 201 is fixedly connected to the top outer wall of the support plate 5, and the rotating rod 202 is rotatably connected to the inner wall of the fixed plate 4; one end of the reset spring 213 is fixedly connected to the inner wall of the rotating rod 202, and the other end of the reset spring 213 is fixedly connected to the outer wall of the moving rod 204, and the outer wall of the moving rod 204 is slidably connected to the inner wall of the rotating rod 202; one end of the hinged rod 210 is hinged to the outer wall of the block 211, and the other end of the hinged rod 210 is hinged to the outer wall of the moving rod 204, and the moving rod 204 is slidably connected to the inner wall of the connecting block 205; the block 211 is slidably connected to the inner wall of the connecting block 205, the block 211 is clamped with the slot 207, and the handle 203 passes through the outer wall of the rotating rod 202.

[0033] The above scheme is adopted: the card slot 207 on the inner wall of the installation block 206 is engaged with the card block 211, and the card block 211 can be moved by the connecting rod 209 on the moving rod 204 through the hinge rod 210. In the case of no external force, the elastic force of the return spring 213 makes the moving rod 204 at the top, and the two groups of hinge rods 210 flip to both sides, and under the elastic force of the connecting spring 212, the two groups of card blocks 211 are located at the positions on both sides, and a part of them is located outside the connecting block 205; when the stirring blade 208 needs to be installed, the handle 203 can be pulled downward, and the handle 203 drives the moving rod 204 to slide downward on the inner wall of the rotating rod 202 and squeeze the return spring 213. At the same time The connecting rod 209 is driven to move downward synchronously, and the hinge rod 210 is driven to flip, so that the blocks 211 on both sides move toward the middle at the same time and retract into the inner wall of the connecting block 205; at this time, the installation block 206 can be docked with the connecting block 205, so that the slot 207 and the position of the block 211 correspond to each other, and the handle 203 is released. The reset spring 213 drives the moving rod 204 to move upward and reset due to the elastic force. The block 211 pops out under the action of the connecting spring 212 and engages with the slot 207, thereby achieving a firm installation of the stirring blade 208; this design facilitates the installation, disassembly and replacement of the stirring blade 208, and does not require disassembly and installation by means of bolts, etc., saving time and effort.

[0034] like Figure 7As shown, the unloading mechanism 3 includes a fixed shaft 301, the outer wall of the fixed shaft 301 is elastically connected to a baffle 303 through a volute spring 302, the outer wall of the support plate 5 is fixedly connected to a solvent tank 305, and the outer wall of the rotating rod 202 is fixedly connected to an extrusion plate 304; the fixed shaft 301 is fixedly connected to the outer wall of the support plate 5, and the extrusion plate 304 contacts the outer wall of the baffle 303; one end of the volute spring 302 is fixedly connected to the inner wall of the baffle 303, and the other end of the volute spring 302 is fixedly connected to the outer wall of the fixed shaft 301; the baffle 303 is rotatably connected to the outer wall of the fixed shaft 301, and the baffle 303 contacts the outer wall of the bottom end of the solvent tank 305;

[0035] The above scheme is adopted: the solvent tank 305 is fixed to the outer wall of the support plate 5, and is used to store the solvent required in the preparation process. The bottom outlet of the solvent tank 305 is opened and closed by the baffle 303. When the baffle 303 is not in contact with the bottom outer wall of the solvent tank 305, the solvent can fall into the preparation tank 1 from the lower opening to add the solvent for preparation; the baffle 303 can rotate around the fixed axis 301 by a certain angle. In the initial state, the volute spring 302 keeps the baffle 303 in a state of closing the outlet of the solvent tank 305. When the rotating rod 202 rotates, the squeezing plate 304 rotates with the rotating rod 202 and contacts the outer wall of the baffle 303, and the squeezing plate 304 applies an external force to the baffle 303 to overcome the volute spring 3 02's elastic force causes the baffle 303 to rotate around the fixed axis 301, thereby opening the outlet of the solvent tank 305, allowing the solvent to flow into the preparation tank 1; when the rotating rod 202 continues to rotate until the extrusion plate 304 is out of contact with the outer wall of the baffle 303, the baffle 303 rotates in the opposite direction and resets under the elastic force of the volute spring 302, closing the opening below the solvent tank 305, thereby realizing the solvent feeding control synchronized with the stirring action through the rotational movement of the rotating rod 202, and can automatically and quantitatively feed the solvent according to the stirring, thereby avoiding the problem of pouring a lot of solvent at one time before stirring and inconvenient stirring and mixing, ensuring the accurate mixing ratio of the material and the solvent during the preparation process, and improving the stability of the preparation and the product quality.

[0036] like Figures 2 to 6 As shown, the outer wall bearing of the stirring blade 208 is connected with a ball 7, the outer wall of the stirring blade 208 is hinged with a control rod 8, and the inner wall of the preparation tank 1 is provided with a guide groove 6.

[0037] The above scheme is adopted: the stirring blades 208 perform circular motion under the drive of the rotating rod 202 to stir the material in the preparation tank 1, and only the outer wall bearing of the top group of stirring blades 208 is connected with the ball 7. When the stirring blades 208 rotate, the ball 7 moves along the inner wall of the guide groove 6, so that the stirring blades 208 rotate more smoothly, and because the guide groove 6 is wavy, it can drive the top group of stirring blades 208 to swing up and down continuously during the rotation process; the two ends of the control rod 8 are respectively hinged to the outer walls of the upper and lower groups of stirring blades 208. During the stirring process, as the top group of stirring blades 208 swing up and down, the remaining multiple groups of stirring blades 208 can be driven to swing synchronously, thereby increasing the mixing effect of the materials in the horizontal and vertical directions, improving the stirring efficiency, and allowing the materials to be more fully mixed and evenly mixed, which is beneficial to the preparation reaction of the battery solid electrolyte.

[0038] The working principle and use process of the present invention:

[0039] First, the operator can place various materials required for preparing the solid electrolyte in the preparation tank 1, and store an appropriate amount of solvent in the solvent tank 305 in advance according to the process requirements, then pour part of the solvent into the preparation tank 1, start the motor 201, and the output shaft of the motor 201 drives the rotating rod 202 to rotate on the inner wall of the fixed plate 4, and the stirring blade 208 performs a circular motion driven by the rotating rod 202 to stir the materials in the preparation tank 1 and the inflowing solvent; the balls 7 on the outer wall of the top group of stirring blades 208 move along the inner wall of the guide groove 6, and because the guide groove 6 is wavy, it drives the top group of stirring blades 208 to swing up and down continuously during the rotation process, and through the control rod 8 hinged between the upper and lower groups of stirring blades 208, as the top group of stirring blades 208 swing up and down, the control rod 8 can drive the remaining multiple groups of stirring blades 208 to swing synchronously, thereby increasing the mixing effect of the materials in the horizontal and vertical directions, so that the materials and the solvent can be mixed more evenly.

[0040] When the rotating rod 202 rotates, the extrusion plate 304 on its outer wall rotates with the rotating rod 202 and contacts the outer wall of the baffle 303. The extrusion plate 304 applies an external force to the baffle 303, causing the baffle 303 to rotate around the fixed shaft 301, and the volute spring 302 is forced to shrink, and the baffle 303 is out of contact with the outer wall of the bottom end of the solvent tank 305, opening the outlet of the solvent tank 305, and the solvent in the solvent tank 305 begins to flow into the preparation tank 1, so that the solvent can be automatically discharged quantitatively. By pre-pouring a small amount of solvent into the preparation tank 1 and then continuously adding the solvent, the solvent can be better mixed with the material for preparing the solid electrolyte, and the problem of difficulty in stirring evenly due to excessive solvent being poured in at one time, resulting in problems such as reduced quality of the preparation, etc.; when the rotating rod 202 continues to rotate until the extrusion plate 304 is out of contact with the outer wall of the baffle 303, the baffle 303 is reversely rotated and reset under the elastic force of the volute spring 302, and the opening below the solvent tank 305 is closed, and the solvent discharge is stopped.

[0041] After long-term use, the stirring blade 208 may need to be disassembled for cleaning or maintenance. When the stirring blade 208 needs to be disassembled, the operator pulls the handle 203 downward, and the handle 203 drives the moving rod 204 to slide downward on the inner wall of the rotating rod 202, squeezing the reset spring 213, and at the same time drives the connecting rod 209 to move downward, and the hinge rod 210 is flipped to make the blocks 211 on both sides retract to the middle at the same time into the inner wall of the connecting block 205 and break away from the card slot 207, so that the installation block 206 and the stirring blade 208 can be removed for maintenance or replacement; when the stirring blade 208 needs to be installed, the handle 203 is also turned to Pull down the handle 203 and insert the mounting block 206 on the outside of the connecting block 205 so that the slot 207 corresponds to the position of the block 211, then release the handle 203, and the reset spring 213 drives the moving rod 204 to move upward and reset due to the elastic force, and drives the connecting rod 209 to move upward, and the two sets of hinged rods 210 flip in the opposite direction, and the block 211 pops out to both sides under the action of the connecting spring 212, and engages with the corresponding slot 207, so that the installation of the stirring blade 208 can be completed conveniently and quickly, and the disassembly and installation process does not need to be carried out by turning the bolts multiple times, which is more time-saving and labor-saving, and easy to operate.
