Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a raw material stirring device for battery separator production. Background Art

[0002] A battery separator is a layer of separator material between the positive and negative electrodes of a battery, which provides the main protection measures for the safety of the battery. At the same time, the battery separator can prevent electrons inside the battery from passing freely, while ions in the battery can pass freely. When in use, isolating the positive and negative electrodes can limit the increase in current in the case of overcharging or temperature rise of the battery.

[0003] For example, a raw material mixing device for battery separator production with the publication number CN215233480U can avoid the internal raw materials splashing on the ground and polluting the environment during material receiving through the provided material receiving device. At the same time, the provided spray head can clean the inside of the main box after stirring ends.

[0004] When the materials of the above device are dissolved and mixed with liquid hydrocarbons, since the stirring roller installed inside the main box rotates along the center of the main box through a turntable driven by a motor and the stirring roller itself does not rotate, it causes the solid materials to easily accumulate towards the center under the drive of the liquid hydrocarbons during the mixing and dissolving process. The solid materials at the center move less, and at the same time, other solid materials continue to accumulate towards the center during the entire stirring process, resulting in insufficient contact between these solid materials and the liquid hydrocarbons and unable to be fully mixed. At the same time, the mixed raw materials are not effectively separated between solid and liquid, resulting in part of the undissolved solids being taken out together with the discharged liquid when finally taking out the mixed liquid, so that the staff needs to perform secondary separation to put the pure liquid raw materials into use. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the existing technology, the utility model provides a raw material stirring device for battery separator production, which has the functions of fully mixing the solid materials and liquid placed inside, and separating the dissolved liquid materials from the solid materials at the same time, ensuring that the raw materials finally taken out from the stirring cylinder are relatively pure.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figures 1 to 3 , which is the first embodiment of the present utility model, and provides a technical solution: a raw material mixing device for battery separator production, including a mixing drum 1, a mixing assembly 2 is arranged inside the mixing drum 1, and the mixing assembly 2 is used to fully mix and stir the put raw materials. A support plate 3 is arranged outside the mixing drum 1, and a liquid storage tank 4 is arranged on the support plate 3. The liquid storage tank 4 is used to store the liquid hydrocarbon for mixing and stirring the raw materials. A liquid delivery pipe 41 is arranged on the side of the liquid storage tank 4 away from the support plate 3;

[0026] The stirring assembly 2 includes a sealing plate 21 movably arranged inside the stirring cylinder 1. The sealing plate 21 fits with the stirring cylinder 1 to divide the internal space of the stirring cylinder 1. A stirring roller 22 is arranged on one side of the sealing plate 21. There is a cavity inside the stirring roller 22, which facilitates the air pump 55 to transport air through the stirring roller 22 to the discharging assembly 5 at the sealing plate 21 to form extrusion to open the discharging assembly 5. The stirring roller 22 is used to rotate and mix the put solid raw materials, so that the solid raw materials can be dissolved and mixed under the action of liquid hydrocarbon. A motor 23 is arranged at one end of the stirring roller 22 away from the sealing plate 21. The motor 23 is used to drive the stirring roller 22 to rotate. A bearing 24 is arranged on the stirring roller 22, and fixing plates 25 are symmetrically arranged on the bearing 24. A matching roller 251 is arranged at one end of the fixing plate 25 away from the bearing 24. The matching roller 251 is used to cooperate with the stirring roller 22 to mix the put raw materials.

[0027] A turbulence ring 26 is arranged on the sealing plate 21. The turbulence ring 26 is used to rotate synchronously under the rotation of the sealing plate 21 to mix the liquid hydrocarbon and solid materials existing inside the stirring cylinder 1. At the same time, it can ensure that the liquid hydrocarbon can flow irregularly when rotating inside the stirring cylinder 1. The sealing plate 21 is provided with liquid outlet holes 211 in an array. The liquid outlet holes 211 are used to cooperate with the elastic piston 53 to isolate the raw materials above the stirring cylinder 1. A discharging assembly 5 is arranged on one side of the sealing plate 21 away from the turbulence ring 26. The discharging assembly 5 is used to take out the liquid materials after mixing is completed, and can also isolate the solids during the taking-out process to avoid solid raw materials remaining in the liquid.

[0028] A sealing cover plate 6 is arranged on the stirring cylinder 1, and the sealing cover plate 6 is rotatably connected with the stirring roller 22. A feeding port 61 is penetrated through the sealing cover plate 6.

[0029] During the use process, first put the solid raw materials inside the stirring cylinder 1, and then add the liquid hydrocarbon required for raw material mixing to the inside of the stirring cylinder 1 through the liquid delivery pipe 41 on the liquid storage bin 4. Driven by the motor 23, the sealing plate 21 and the stirring roller 22 rotate synchronously. During the rotation process, due to the rotation connection between the matching roller 251 fixedly connected to the sealing cover plate 6 and the stirring roller 22 through the bearing 24 on the fixing plate 25, the matching roller 251 can cooperate with the stirring blades on the stirring roller 22 to stir the raw materials. During the stirring process, the raw materials and the liquid hydrocarbon are fully mixed. During the mixing process, the turbulence ring 26 can prevent the liquid hydrocarbon from driving the solids to converge towards the center of the stirring cylinder 1 when rotating inside the stirring cylinder 1, resulting in slower overall stirring efficiency. After mixing is completed, the discharging assembly 5 can be opened to discharge the mixed raw materials, and at the same time, it can prevent the solids that have not been fully dissolved from entering the discharging area of the stirring cylinder 1.

[0030] Embodiment 2

[0031] Please refer to Figures 1 to 4 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is as follows:

[0032] The discharging assembly 5 includes a telescopic ring 51 arranged on one side of the closed plate 21. The telescopic ring 51 can be telescopic and forms a closed space between the closed plate 21 and the closed circular plate 52. The closed circular plate 52 is arranged on the side of the telescopic ring 51 away from the closed plate 21. The elastic pistons 53 are arranged in an array on one side of the closed circular plate 52. The elastic pistons 53 are conical and are used to cooperate with the liquid outlet holes 211 to isolate the raw materials above the closed plate 21. The air inlet pipe 54 penetrates through the stirring roller 22. The air pump 55 is arranged at one end of the air inlet pipe 54 away from the stirring roller 22. The air pump 55 is used to send air into the closed space formed inside the telescopic ring 51 through the air inlet pipe 54 to make the telescopic ring 51 extend.

[0033] A protection cylinder 56 is arranged in an array on the side of the closed circular plate 52 close to the elastic piston 53. A spring 57 is arranged inside the protection cylinder 56, and both ends of the spring 57 are fixedly connected between the closed circular plate 52 and the closed plate 21 respectively. The spring 57 is used to pull the closed circular plate 52 so that the elastic piston 53 on the closed circular plate 52 can block the liquid outlet holes 211. At the same time, several installed springs 57 can carry the materials on the closed plate 21 so that the whole will not become loose. A check valve 541 is arranged on the air inlet pipe 54.

[0034] An observation port 11 is arranged on one side of the mixing cylinder 1. The observation port 11 is used to observe the mixing condition inside the mixing cylinder 1. And a discharging valve 12 is arranged on the side of the mixing cylinder 1 away from the cover plate 6.

[0035] During the use process, when the mixed raw materials need to be taken out, the air pump 55 conveys air into the inner cavity of the stirring roller 22 to form high pressure, thereby forcing the telescopic ring 51 on the closed plate 21 fixedly connected to the other end of the stirring roller 22 to open. When the telescopic ring 51 opens, the elastic pistons 53 installed on the closed circular plate 52 move synchronously, opening the liquid outlet holes 211 of the closed plate 21, so that the mixed raw materials can flow out along the liquid outlet holes 211. The size of the liquid outlet holes 211 is small and cannot allow the undissolved solid raw materials to pass through, separating the solid and liquid of the raw materials inside the mixing cylinder 1. At the same time, the work between the stirring roller 22 and the turbulence ring 26 arranged can move the solids at the liquid outlet holes 211 and will not cause blockage to the liquid outlet holes 211.

[0036] The remaining structures are the same as those in Embodiment 1.

[0037] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
