The adhesive circulating tank with dual filtering function includes mixing tank, glue return filter, glue outlet filter, rubber discharge pipe. The glue inlet of glue return filter is connected with separator, and the glue outlet of glue return filter is connected with mixing tank. The glue outlet filter is set between mixing tanks of circulating pump, and the circulating pump is connected with glue outlet filter through glue outlet pipe, A glue outlet filter is added between the circulating pump and the mixing tank, which can effectively filter the recovered glue flowing into the separator and prevent glass fiber from flowing into the mixing tank with the glue. A glue outlet filter is added between the circulating pump and the mixing tank, which can ensure that the glue supplied to the overflow plate does not contain glass fiber, so as to ensure the quality of glass fiber felt. In the actual use process, The normal production can be ensured as long as the return filter and outlet filter are disassembled and cleaned regularly.
