Description

Technical Field

[0001] The invention relates to the technical field of stirring and mixing, and in particular to a high-temperature mixing device for gel electrolyte raw materials. Background Art

[0002] When preparing high-performance battery electrolytes, the gel electrolyte raw materials need to be mixed at high temperatures to ensure that the components are evenly dispersed, thereby ensuring the uniformity and electrochemical performance of the electrolyte.

[0003] At present, the heating module is usually set at the bottom of the mixing barrel, which causes the gel electrolyte raw material close to the heating module to have a faster heat conduction speed, and the gel electrolyte raw material far from the heating module to have a slower heat conduction speed. The uneven heat conduction performance leads to uneven temperature distribution of the raw materials. Local overheating can cause thermal decomposition and chemical reactions of the raw materials, generate harmful byproducts, affect the performance of the electrolyte, and ultimately reduce the battery's charge and discharge efficiency and cycle life, and reduce safety. At the same time, uneven temperature can also cause phase separation and viscosity changes of the raw materials, affecting the mixing uniformity, which may increase the internal resistance of the battery and cause inconsistent performance.

DETAILED DESCRIPTION

[0035] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Embodiment 1: A high temperature mixing device for gel electrolyte raw materials, combined with the attached Figure 1 To Attachment Fig. 9The invention comprises a base 101, a stirring barrel 102 is fixedly connected to the top of the base 101, a cover plate 103 is fixedly connected to the top of the stirring barrel 102, a circular heating plate 104 is fixedly connected to the bottom of the stirring barrel 102, a conversion cylinder 105 is fixedly connected to the bottom of the stirring barrel 102, the outer wall of the conversion cylinder 105 contacts the inner wall of the heating plate 104, the lower part of the conversion cylinder 105 is provided with through holes evenly distributed in the circumferential direction, the gel electrolyte raw material in the stirring barrel 102 enters the conversion cylinder 105 through the through holes, and the top of the conversion cylinder 105 is provided with a cylinder mouth The conversion cylinder 105 is open, and the rotating frame 106 is connected to the conversion cylinder 105 in an axially penetrating manner. The rotating frame 106 is splined with a sliding frame 107, so that the sliding frame 107 can slide up and down along the rotating frame 106, and the rotating frame 106 can drive the sliding frame 107 to rotate. The sliding frame 107 and the rotating frame 106 are both composed of a vertical portion at the bottom and a horizontal portion at the top. The horizontal portion at the top of the sliding frame 107 is provided with three circumferentially distributed spiral grooves 1071. The base 101 is fixed with a cylinder 108. The cylinder 1 The telescopic end of the rotating frame 108 is fixedly connected with a connecting ring 109, and the connecting ring 109 is rotatably connected with the sliding frame 107. The outer wall of the rotating frame 106 is fixedly connected with a spiral conveying frame 110, and the spiral conveying frame 110 is used to transfer the gel electrolyte raw material in the lower high temperature zone upward to the upper low temperature zone. The rear side of the cover plate 103 is fixedly connected with a one-way feeding pipe 113, and the gel electrolyte raw material enters the stirring barrel 102 in one direction through the one-way feeding pipe 113. The horizontal part of the upper part of the rotating frame 106 is rotatably connected with three first stirring blades 111 uniformly distributed in the circumferential direction. 4. The first stirring blade 114 corresponds to the spiral groove 1071 one by one, and the first stirring blade 114 is slidably connected to the corresponding spiral groove 1071. A temperature sensor 1041 is fixedly connected to the front side of the cover plate 103, and the temperature sensor 1041 is electrically connected to the cylinder 108 through the control module. The left and right sides of the cover plate 103 are respectively fixedly connected to the inlet pipe 111 and the outlet pipe 112. The base 101 is fixedly connected to the first motor 201, and a pulley assembly 202 is connected between the output shaft of the first motor 201 and the rotating frame 106.

[0037] First, the gel electrolyte raw materials to be mixed are poured into the stirring barrel 102 through the one-way feeding pipe 113, and then the heating plate 104 is turned on to heat the raw materials in the stirring barrel 102 at high temperature, and then the first motor 201 is started. The first motor 201 drives the rotating frame 106 to rotate through the pulley assembly 202, thereby driving the first stirring blade 114 to rotate, and then the raw materials in the stirring barrel 102 are stirred and mixed.

[0038] During the high-temperature mixing process, since the lower raw materials are close to the heating plate 104, the temperature of the raw materials in the lower part of the mixing barrel 102 is higher than that of the upper raw materials, resulting in uneven heating of the upper and lower raw materials. Specifically, uniform heating is achieved by the following operations: when the rotating frame 106 rotates, the spiral conveying frame 110 is driven to rotate synchronously, and the high-temperature raw materials in the lower part of the mixing barrel 102 penetrate into the conversion barrel 105 through the through holes evenly distributed at the lower part of the conversion barrel 105, and under the conveying action of the spiral conveying frame 110, the raw materials spirally flow upward to the barrel mouth at the top of the conversion barrel 105, and then mix into the low-temperature raw materials in the upper part of the mixing barrel 102. In the raw materials of the first stirring plate 114, the circulating flow makes the present invention, on the basis of the stirring and mixing by the first stirring plate 114, through the upward and downward flow of the raw materials, not only can the degree of uniform mixing of the raw materials be enhanced, but also the raw materials flow from the high temperature zone to the low temperature zone, so that the overall temperature of the raw materials can be synchronously increased, thereby avoiding local overheating caused by uneven heating, thereby avoiding thermal decomposition of certain raw materials or initiation of chemical reactions, generating harmful by-products, affecting the chemical stability and electrochemical properties of the electrolyte, and avoiding phase separation and inconsistent viscosity changes due to temperature differences, thereby avoiding the formation of an uneven mixture.

[0039] In the above process, when the temperature sensor 1041 detects that the temperature of the raw material is higher than the preset value, the temperature sensor 1041 controls the cylinder 108 to shorten through the control module, and the cylinder 108 pulls the sliding frame 107 downward through the connecting ring 109. The sliding frame 107 drives the first stirring blade 114 to rotate a certain angle relative to the rotating frame 106 through the spiral groove 1071 to retract, so as to reduce the contact area between the first stirring blade 114 and the raw material, so that the first stirring blade 114 rotates more gently, reduces the shear force, reduces the frictional heat, reduces the generation of local high temperature areas, and avoids the thermal decomposition or volatilization of the raw material due to local high temperature, thereby protecting the chemical stability and physical properties of the raw material.

[0040] When the temperature sensor 1041 detects that the temperature of the raw materials is lower than the preset value, the temperature sensor 1041 controls the extension of the cylinder 108 through the control module, and the cylinder 108 pushes the sliding frame 107 to move upward through the connecting ring 109. The sliding frame 107 drives the first stirring blade 114 to rotate a certain angle relative to the rotating frame 106 through the spiral groove 1071 to expand, so as to increase the contact area between the first stirring blade 114 and the raw material, increase the shear force of the first stirring blade 114, and thus mix the raw materials more quickly.

[0041] That is, the present invention dynamically adjusts the angle of the first stirring blade 114 to quickly mix the raw materials at low temperatures and protect the raw materials at excessively high temperatures, thereby better adapting to the mixing requirements of different stages and improving the efficiency and quality of the entire mixing process.

[0042] In addition, the air inlet pipe 111 is connected to the output pipe of the external nitrogen pump, and nitrogen is introduced through the air inlet pipe 111. The nitrogen squeezes out the air in the stirring barrel 102 through the air outlet pipe 112. In this way, the raw materials are protected by inert gas during the mixing process to prevent certain raw materials of the gel electrolyte from undergoing oxidation reaction with oxygen in the air or reduction reaction with reducing substances at high temperature, thereby avoiding deterioration of the raw materials and further avoiding affecting the chemical stability and electrochemical properties of the electrolyte.

[0043] Embodiment 2, on the basis of embodiment 1, combined with the attached Fig.10 , and also includes a pulling frame 301, which is rotatably connected to the top of the sliding frame 107, and the cover plate 103 is slidably connected to an opening and closing frame 302 symmetrically distributed along the pulling frame 301, and the opening and closing frames 302 symmetrically distributed on the left and right are respectively slidably connected to the air inlet pipe 111 and the air outlet pipe 112, and an inclined groove is opened on the side of the opening and closing frame 302 close to the pulling frame 301, and the opening and closing frame 302 is slidably connected to the pulling frame 301 through the inclined groove, and the pulling frame 301 can move up and down to control the opening and closing of the opening and closing frame 302 through the inclined groove.

[0044] First, the cylinder 108 is manually controlled to shorten, so that the sliding frame 107 moves downward to drive the pulling frame 301 to move downward, and the pulling frame 301 pulls the opening and closing frame 302 to move toward the middle, so that the air inlet pipe 111 and the air outlet pipe 112 are no longer closed by the opening and closing frame 302. At this time, nitrogen is introduced through the air inlet pipe 111. When the air in the mixing barrel 102 is completely squeezed out and the mixing barrel 102 is filled with nitrogen, the cylinder 108 is controlled to extend, so that the air inlet pipe 111 and the air outlet pipe 112 are closed by the opening and closing frame 302. Afterwards, when the temperature sensor 1041 detects that the temperature is higher than the preset value, the cylinder 108 is automatically controlled to shorten, so that the opening and closing frame 302 is opened, so that the cold nitrogen enters the mixing barrel 102 through the air inlet pipe 111, and the hot nitrogen is discharged through the air outlet pipe 112. In this way, the exchange operation of cold and hot nitrogen is realized, and the internal reaction heat is reduced when the temperature is too high.

[0045] Embodiment 3, on the basis of embodiment 2, combined with the attached Fig.11 , also includes a first gear 401, the first gear 401 is fixedly connected to the upper part of the conversion cylinder 105, a fixed block 402 symmetrically distributed along the upper and lower sides of the first stirring blade 114 is fixedly connected, and a second stirring blade 403 is rotatably connected between the fixed blocks 402 on the adjacent upper and lower sides, and the second stirring blade 403 is located between the first stirring blade 114 and the conversion cylinder 105, and a second gear 404 is fixedly connected to the top of the second stirring blade 403, and the second gear 404 is meshed with the first gear 401.

[0046] When the first stirring blade 114 rotates, it drives the fixed block 402 to rotate, thereby driving the second stirring blade 403 to rotate, and then driving the second gear 404 to rotate around the first gear 401. In this way, the first gear 401 drives the second stirring blade 403 to rotate, so as to stir the raw materials between the first stirring blade 114 and the gap between the conversion cylinder 105 to avoid insufficient stirring in local areas.

[0047] Embodiment 4, on the basis of embodiment 3, combined with the attached Fig.12 , also includes an air guide frame 501, the air guide frame 501 is fixedly connected to the cover plate 103, the top of the air inlet pipe 111 is connected to the copper tube 502, the copper tube 502 is located in the air guide frame 501, a second motor 503 is fixedly connected to the top right side of the air guide frame 501, the temperature sensor 1041 is electrically connected to the second motor 503 through the control module, the output shaft of the second motor 503 is fixedly connected to a heat dissipation fan 504, the heat dissipation fan 504 is located in the air guide frame 501, and the left and right sides of the air guide frame 501 are set to be open, respectively used for air outlet and air intake.

[0048] The output pipe of the external nitrogen pump is connected to the copper tube 502. When the temperature sensor 1041 detects that the temperature is higher than the preset value, the temperature sensor 1041 controls the second motor 503 to start through the control module, thereby driving the heat dissipation fan 504 to rotate. At the same time, the opening and closing frame 302 is opened, and the incoming nitrogen first transfers its own heat to the copper tube 502. The heat dissipation fan 504 blows toward the copper tube 502, so that the heat on the copper tube 502 is discharged through the outlet on the left side of the air guide frame 501. Finally, the nitrogen after cooling enters the mixing barrel 102 through the air inlet pipe 111. In this way, the present invention guides the heat of the incoming nitrogen through the copper tube 502, and then blows away the heat on the copper tube 502 through the heat dissipation fan 504, ensuring that the incoming nitrogen is low-temperature nitrogen, thereby ensuring the feasibility of the cold and hot nitrogen exchange operation.
