First, turn the interface of the old mesh belt on the filter press equipment to the position where it is convenient to disassemble the interface. Loosen the old mesh belt and pull out the steel wire for interface connection. Then connect the new belt with the old belt. Start the machine, pull out the old belt and bring the new belt into the equipment. When all the old belts are pulled out of the equipment, remove the old belts from the new belts. The steel buckles at both ends of the new belt are crossed and butted together, and are threaded and tensioned with stainless steel wires.
