Description

Technical Field

[0001] The utility model relates to the technical field of vibration equipment, and more specifically, to a material feeding vibration device for lithium battery materials. Background Art

[0002] Usually, companies will install vibrators on the outer walls of silos, spirals, pipes, etc. to promote material circulation. However, existing vibrators are prone to friction with the surface of equipment after long-term use, causing equipment loss and generating metal powder. As the material is transported, these powders will enter the equipment in the form of metal foreign matter, causing material contamination. Some companies, such as the lithium battery industry, have very strict control over metal foreign matter. The presence of metal foreign matter will have a great impact on the safety performance of the battery. Larger metal particles will penetrate the diaphragm during physical extrusion and cause mechanical short circuits, or be oxidized into metal ions during charging and migrate to the negative electrode of the battery. They will be deposited on the negative electrode to form dendrites and then pierce the diaphragm to cause chemical short circuits, resulting in high battery self-discharge, capacity attenuation, battery heating, and even fire and explosion. Therefore, how to reduce the generation of metal foreign matter in the process of assisting material circulation through mechanical vibration is a technical problem to be solved in this application.

[0025] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0026] The utility model relates to a material feeding vibration device for the field of lithium battery materials, comprising a turbine vibrator, a protective pad, a gas regulating mechanism, and a muffler. The utility model has a simple structure and is easy to operate. After installing the device, it can not only ensure the smooth flow of materials and avoid the introduction of metal foreign matter, but also meet the environmental protection requirements of the workshop noise. The overall noise of a single device is reduced by more than 10dB compared with an ordinary turbine vibrator.

[0027] See also Figure 1 The utility model discloses a lithium battery material feeding vibration device, comprising a pneumatic vibrator 4, a protective pad 1, a muffler 7, a muffler layer 2, an outer cover 3, a gas regulating mechanism, a flow monitoring mechanism and a PLC.

[0028] The pneumatic vibrator 4 can be a small turbine vibrator, including a vibration output surface, which is fixed to the outer wall of the unloading device by bolts. The unloading device can be a silo, a spiral, a pipeline, etc. The pneumatic vibrator 4 can generate vibration to ensure the flow of materials.

[0029] The protective pad 1 is attached to the vibration output surface so that it is located between the outer wall of the silo, spiral, pipeline and the like and the vibration output surface after installation, so as to avoid the pneumatic vibrator 4 and the equipment surface from wearing and producing metal foreign matter, and ensure that the equipment is not cracked by the pneumatic vibrator 4, avoid the generation of metal foreign matter in the workshop, and ensure product quality. The material of the protective pad 1 is selected from non-metallic elastic materials, and the specific material can be selected from polyurethane, silicone and other materials, which can reduce the generation of metal foreign matter, and preferably open-pore polyurethane soft foam or energy-absorbing foam, which, on the premise of isolating the equipment, also has good sound absorption and shock absorption function, good anti-compression load performance and deformation recovery performance, thereby further reducing the noise problem of the pneumatic vibrator 4. Or choose silicone with the same properties, which is a highly active adsorption material, does not react with any substance except strong alkali and hydrofluoric acid, is insoluble in water and any solvent, is non-toxic and tasteless, has stable chemical properties, has good toughness and elasticity, is not easy to be permanently deformed by external force, and has high mechanical strength. Of course, you can also choose polyurethane rigid foam, which can ensure the vibration effect of the turbine vibrator on the equipment based on its high strength and excellent toughness.

[0030] The gas regulating mechanism includes an air intake pipeline 5 connected to the air intake end of the pneumatic vibrator 4 and a regulating valve 6 arranged on the air intake pipeline 5. The regulating valve 6 is used to adjust the air intake amount of the pneumatic vibrator 4 to control the vibration generated by the pneumatic vibrator 4. While ensuring the normal flow of materials in the equipment, the opening of the regulating valve 6 can be appropriately reduced to reduce the damage of the pneumatic vibrator 4 to the equipment, avoid the generation of metal foreign matter, and reduce the noise generated.

[0031] Furthermore, the regulating valve is an electrically controlled regulating valve, and the flow monitoring mechanism is arranged in the unloading device. The PLC is electrically connected to the flow monitoring mechanism and the electrically controlled regulating valve respectively. The flow monitoring mechanism feeds back the blockage condition of the material to the PLC in the form of an electrical signal. The PLC adjusts the opening of the electrically controlled regulating valve according to the signal feedback to realize automatic adjustment of the air intake volume of the pneumatic vibrator 4.

[0032] The silencer 7 is installed in the direction of the noise of the pneumatic vibrator 4 to prevent the noise from escaping to the outside and polluting the environment. The hardness of the shell material of the silencer 7 is less than the hardness of the shell material of the pneumatic vibrator, and the shell material of the silencer is a non-metallic material. Preferably, the silencer 7 is made of plastic material to reduce the generation of metal impurities; the silencer layer 2 is made of silencer cotton, which is wrapped around the pneumatic vibrator 4 and the outer periphery of the silencer 7 to absorb the noise generated by the vibration of the pneumatic vibrator 4. In addition, the wrapping of the silencer cotton needs to ensure the airflow of the silencer 7.

[0033] In order to ensure the stability of the silencing cotton and the aesthetics of the pneumatic vibrator 4, the outer surface of the silencing layer 2 is wrapped with an outer cover 3. Under the premise of ensuring airflow, exhaust holes are opened in the outer cover 3 at the exhaust port position corresponding to the muffler 7 to discharge the gas.

[0034] In summary, the lithium battery material unloading vibration device provided by the utility model comprises a pneumatic vibrator 4, a protective pad 1, a gas regulating mechanism, and a silencer. The pneumatic vibrator 4 generates vibrations to ensure the smooth flow of materials in the equipment. The protective pad 1 is installed between the pneumatic vibrator 4 and the surface of the equipment to avoid wear and tear to produce metal foreign matter and to prevent the equipment from being vibrated and cracked. The gas regulating mechanism adjusts the air intake of the pneumatic vibrator 4 by the regulating valve 6 to control the vibration generated by the pneumatic vibrator. While ensuring the normal flow of materials in the equipment, the opening of the regulating valve 6 can be appropriately reduced to reduce the damage of the turbine vibrator to the equipment and reduce the noise generated. The silencer consists of a silencer layer 2 and a silencer 7. The silencer layer 2 is installed on the surface of the pneumatic vibrator 4 to absorb the noise generated by the pneumatic vibrator. The silencer 7 is installed in the direction of the noise of the pneumatic vibrator 4 to prevent the noise from escaping to the outside and polluting the environment.
