Description

Back-blowing cleaning filter

Technical Field

The application relates to the technical field of dust treatment, in particular to a back-blowing cleaning filter.

Background

Lithium batteries are batteries using a nonaqueous electrolyte solution, in which lithium metal or a lithium alloy is used as a positive electrode material and a negative electrode material. Lithium batteries are widely used in energy storage power systems of hydraulic power, fire power, wind power, solar power stations and the like. Lithium batteries can be roughly classified into lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain lithium in the metallic state and can be charged. Because the positive electrode raw material of the lithium battery is manganese dioxide, in the production process of the lithium battery, the manganese dioxide needs to be mixed according to a certain proportion, and a bowl filling machine needs to be used for adding the raw material.

At present, in order to ensure the balance of the pressure difference between the inside and the outside of a bin of a bowl filling machine and ensure that manganese dioxide can smoothly fall into the bowl filling machine, the bin of the bowl filling machine is generally provided with an air pressure balance port. However, when fine powder with high metering accuracy is added into and discharged from the bin of the bowl filler, the raised fine powder leaks out of the bin through the air pressure balancing port, so that the environment of a factory building is affected. In order to prevent this, a filter device is generally installed in the air pressure equalizing port.

In view of the above-mentioned related technologies, the inventor believes that in the currently-used filtering device, when filtering, clean air is discharged from the bin, and fine dust adheres to the filter cartridge of the filtering device under the action of pressure difference, thereby affecting the metering accuracy of ingredients.
