Description

Technical Field

[0001] The utility model belongs to the technical field of lithium ion batteries, and in particular relates to a mixing, conveying and dispersing device for high-viscosity liquid materials. Background Art

[0002] As a key process in the production of lithium batteries, the preparation of battery slurry plays a decisive role in the performance of lithium batteries. Liquid materials include solvents, additives, etc., which are weighed according to the formula ratio and added to the slurry making equipment to mix, stir and disperse with the powder materials to obtain a uniform and stable slurry. Various liquid additives need to be dissolved and dispersed with solvents to prepare the required concentration before being used in the production of slurry.

[0003] At present, the incoming materials are mostly in a crystalline state or a highly viscous state in their initial state. The existing production adopts a diaphragm pump extraction and pumping method. For materials that are in a crystalline state at low temperatures, they must be heated and melted and then manually poured into a dispersion device for dissolution and dispersion. After the material is absorbed, the pumping method has no power for pumping, and the material will remain in the pipeline. During the loading and transportation process, it will cause poor flow and residue in the pipeline, making it difficult to clean the subsequent pipeline and wasting materials; manual pouring into the dispersion device causes a large workload for operators and inconvenient operation. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-viscosity liquid material mixing, conveying and dispersing device, comprising a dissolving and stirring tank, a heating tank, a disperser, a solvent tank and a high-viscosity material tank;

[0006] Wherein, the dissolving and stirring tank is provided with a vacuum interface for evacuating the interior of the dissolving and stirring tank;

[0007] The dissolving and stirring tank is connected to one end of the disperser through a pipeline, and the other end of the disperser is connected to the solvent tank and the high-viscosity material tank respectively through a suction gun;

[0008] The solvent tank and the high-viscosity material tank are respectively placed in the heating tank.

[0009] Preferably, the disperser is installed in a dispersion tank.

[0010] Preferably, a cleaning tank is also provided in the heating tank.

[0011] Preferably, a valve is provided on the suction gun.

[0012] Preferably, a weighing module is provided on the dissolving and stirring tank.

[0013] Preferably, the vacuum interface is installed on the top of the dissolution stirring tank.

[0014] Preferably, a dispersion motor is provided in the middle of the upper part of the dissolving and stirring tank, and a stirring shaft is provided at the lower part of the dispersion motor, and the stirring shaft extends deep into the interior of the dissolving and stirring tank.

[0015] Preferably, a valve is provided on the pipeline.

[0016] Preferably, universal wheels are installed at the bottom of the dissolving and stirring tank.

[0017] Preferably, a manual valve or a solenoid valve is provided on the vacuum interface.

[0018] The beneficial effects of the utility model are as follows: compared with the prior art, the device reduces the viscosity of the material by preheating the incoming material, making the material have better fluidity, and further reduces the viscosity by effectively mixing with the solvent through the dispersion device when the material is transported at the beginning through vacuum as the power. The material is better transported and the dissolution and dispersion time is shortened in the dissolution tank. The whole process can make the pipeline free of high-viscosity material residue and re-crystallization. The waste caused by the residue of the material in the pipeline and the labor intensity of manually cleaning the pipeline are reduced. The problem of pipeline blockage in the next batch of use is solved. BRIEF DESCRIPTION OF THE DRAWINGS

A vacuum suction method is adopted through the vacuum interface 12, and the pipeline from the suction gun to the dissolving and stirring tank is in a negative pressure state during the suction process, thereby preventing the residual material in the pipeline.

[0023] The solvent tank and the high-viscosity material tank are respectively placed in the heating tank. The materials fed into the heating tank are preheated in advance to reduce the viscosity of the materials and increase their fluidity.

[0024] Specifically, the disperser is installed in the dispersion tank 10. The pipeline disperser 9 is used to dissolve and disperse the high-viscosity material and the solvent before transportation, so as to prevent the transportation of a single high-viscosity material in the pipeline.

[0025] Specifically, the heating tank is further provided with a cleaning tank 7. The cleaning tank is also filled with a solvent for cleaning the second suction gun 5. After the high-viscosity material is sucked, the suction gun B is placed in the solvent 7 to suck the solvent, and the high-viscosity suction pipeline is flushed to prevent residue.

[0026] In order to control the opening and closing of the suction gun, a valve 8 is provided on the suction gun.

[0027] In order to weigh the mixed raw materials in the dissolving and stirring tank, a weighing module 11 is provided on the dissolving and stirring tank.

[0028] Specifically, the vacuum interface is installed on the top of the dissolving and stirring tank, or can be installed on the side of the dissolving and stirring tank.

[0029] Specifically, the specific structure of the dissolving and stirring tank is as follows: a dispersion motor 13 is provided in the middle of the upper part of the dissolving and stirring tank, and a stirring shaft is provided at the lower part of the dispersion motor, and the stirring shaft goes deep into the dissolving and stirring tank. A universal wheel is installed at the bottom of the dissolving and stirring tank. A manual valve or a solenoid valve is provided on the vacuum interface.

[0030] The working principle of this device is as follows: First, according to the required concentration after dissolution and stirring, the high-viscosity material and the solvent are weighed in advance, the solvent is divided into two parts of equal weight, and the weighed high-viscosity material and solvent are placed in the corresponding high-viscosity material tank and solvent tank respectively. Then preheat according to the set temperature, and after the high-viscosity material and the solvent reach the set temperature, open the vacuum interface 12 valve to pump the dissolving and stirring tank 1 into negative pressure. Then put the first suction gun 3 and the second suction gun 5 into the high-viscosity material tank and the solvent tank, open the valve 8 according to the required flow rate, and the material is dispersed and diluted through the disperser 9, and sucked into the dissolving and stirring tank 1 under the action of negative pressure. Finally, after the high-viscosity material is sucked, the second suction gun 5 is placed in the cleaning tank, and the pipeline is cleaned with a single solvent to prevent the high-viscosity material from adhering to the pipe wall.

[0031] It should be pointed out that the device can be used to transport semi-finished lithium batteries, provide vacuum or inert gas according to requirements, and select different accessories for combination to make full use of space and improve work efficiency. For ordinary technicians in this technical field, without departing from the principle of the utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the scope of protection of the utility model.
