A distributed drying device for easy cleaning and recovery of diaphragm

Abstract

A distributed drying device for easy cleaning and recovery of the diaphragm, including a first-level drying box and a second-level drying box, the first-level drying box and the second-level drying box are installed at intervals in the production workshop, and the first-level drying box and the second-level drying box Leave room for cleaning personnel to enter and exit these drying boxes. Both the first-level drying box and the second-level drying box are vertical boxes. There are several drying rollers in the first-level drying box and the second-level drying box. The rollers are fixedly installed in the drying box along the radial direction of these drying boxes. Each drying roller is arranged in an array, and a slight negative pressure is formed in the secondary drying box, so that a small amount of external air can enter the secondary drying box to prevent secondary drying. The dichloromethane gas in the box overflows to the outside of the secondary drying box. The invention prevents dichloromethane gas from leaking into the production workshop, and cleaning personnel can clean all the drying rollers in the drying box at the same time, avoiding the drying rollers or certain parts that cannot be cleaned.

Description

technical field [0001] The invention relates to the technical field of diaphragm processing devices, in particular to a distributed drying device for diaphragms that is convenient for cleaning and recycling. Background technique [0002] Diaphragm is an important part of lithium battery or other batteries, which plays an important role in the normal use and performance maintenance of lithium battery. In the process of producing the diaphragm, the diaphragm needs to be dried on the drying device. During the transmission process of the diaphragm on the drying roller of the drying device, some white precipitates will be deposited on the surface of the drying roller. Therefore, the drying roller needs to be cleaned regularly to avoid damage. Diaphragm quality impact. Existing drying devices for diaphragms are generally of an integrated horizontal structure, that is, all drying rollers are connected side by side and sequentially connected together and installed horizontally in t...
